their work load increased if they chose to use an assessment method that evaluates students holistically. Adoption and removal Australia In the early 1990s, all states and territories in Australia developed intended curriculum documents largely based on OBE for their primary and secondary schools. Criticism arose shortly after implementation. Critics argued that no evidence existed that OBE could be implemented successfully on a large scale, in either the United States or Australia. An evaluation of Australian schools found that implementing OBE was difficult. Teachers felt overwhelmed by the amount of expected achievement outcomes. Educators believed that the curriculum outcomes did not attend to the needs of the students or teachers. Critics felt that too many expected outcomes left students with shallow understanding of the material. Many of Australia’s current education policies have moved away from OBE and towards a focus on fully understanding the essential content, rather than learning more content with less understanding. Western Australia Officially, an agenda to implement Outcomes Based Education took place between 1992 and 2008 in Western Australia. Dissatisfaction with OBE escalated from 2004 when the government proposed the implementation of an alternative assessment system using OBE 'levels' for years 11 and 12. With government school teachers not permitted to publicly express dissatisfaction with the new system, a community lobby group called PLATO as formed in June 2004 by high school science teacher Marko Vojkavi. Teachers anonymously expressed their views through the website and online forums, with the website quickly became one of the most widely read educational websites in Australia with more 180,000 hits per month and contained an archive of more than 10,000 articles on the subject of OBE implementation. In 2008 it was officially abandoned by the state government with Minister for Education Mark McGowan remarking that the 1990s fad "to dispense with syllabus" was over. European Union In December 2012, the European Commission presented a new strategy to decrease youth unemployment rate, which at the time was close to 23% across the European Union . The European Qualifications Framework calls for a shift towards learning outcomes in primary and secondary schools throughout the EU. Students are expected to learn skills that they will need when they complete their education. It also calls for lessons to have a stronger link to employment through work-based learning (WBL). Work-based learning for students should also lead to recognition of vocational training for these students. The program also sets goals for learning foreign languages, and for teachers continued education. It also highlights the importance of using technology, especially the internet, in learning to make it relevant to students. Hong Kong Hong Kong’s University Grants Committee adopted an outcomes-based approach to teaching and learning in 2005. No specific approach was created leaving universities to design the approach themselves. Universities were also left with a goal of ensuring an education for their students that will contribute to social and economic development, as defined by the community in which the university resides. With little to no direction or feedback from the outside universities will have to determine if their approach is achieving its goals on their own. Malaysia OBE has been practiced in Malaysia since the 1950s; however, as of 2008, OBE is being implemented at all levels of education, especially tertiary education. This change is a result of the belief that the education system used prior to OBE inadequately prepared graduates for life outside of school. The Ministry of Higher Education has pushed for this change because of the number of unemployed graduates. Findings in 2006 state that nearly 70% of graduates from public universities were considered unemployed. A further study of those graduates found that they felt they lacked, job experience, communication skills, and qualifications relevant to the current job market. The Malaysian Qualifications Agency (MQA) was created to oversee quality of education and to ensure outcomes were being reached. The MQA created a framework that includes eight levels of qualification within higher education, covering three sectors; skills, vocational and technical, and academic. Along with meeting the standards set by the MQA, universities set and monitor their own outcome expectations for students South Africa OBE was introduced to South Africa in the late 1990s by the post-apartheid government as part of its Curriculum 2005 program. , Initial support for the program derived from anti-apartheid education policies. The policy also gained support | into instructor, trainer, facilitator, and/or mentor based on the outcomes targeted. Outcome-based methods have been adopted in education systems around the world, at multiple levels. Australia and South Africa adopted OBE policies from the 1990s to the mid 2000s, but were abandoned in the face of substantial community opposition. The United States has had an OBE program in place since 1994 that has been adapted over the years. In 2005, Hong Kong adopted an outcome-based approach for its universities. Malaysia implemented OBE in all of their public schools systems in 2008. The European Union has proposed an education shift to focus on outcomes, across the EU. In an international effort to accept OBE, The Washington Accord was created in 1989; it is an agreement to accept undergraduate engineering degrees that were obtained using OBE methods. As of 2017, the full signatories are Australia, Canada, Taiwan, Hong Kong, India, Ireland, Japan, Korea, Malaysia, New Zealand, Russia, Singapore, South Africa, Sri Lanka, Turkey, the United Kingdom, Pakistan, China and the United States. Differences from traditional education methods OBE can primarily be distinguished from traditional education method by the way it incorporates three elements: theory of education, a systematic structure for education, and a specific approach to instructional practice. It organizes the entire educational system towards what are considered essential for the learners to successfully do at the end of their learning experiences. In this model, the term "outcome" is the core concept and sometimes used interchangeably with the terms "competency, "standards, "benchmarks", and "attainment targets". OBE also uses the same methodology formally and informally adopted in actual workplace to achieve outcomes. It focuses on the following skills when developing curricula and outcomes: Life skills; Basic skills; Professional and vocational skills; Intellectual skills; Interpersonal and personal skills. In a regional/local/foundational/electrical education system, students are given grades and rankings compared to each other. Content and performance expectations are based primarily on what was taught in the past to students of a given age of 12-18. The goal of this education was to present the knowledge and skills of an older generation to the new generation of students, and to provide students with an environment in which to learn. The process paid little attention (beyond the classroom teacher) to whether or not students learn any of the material. Benefits of OBE Clarity The focus on outcomes creates a clear expectation of what needs to be accomplished by the end of the course. Students will understand what is expected of them and teachers will know what they need to teach during the course. Clarity is important over years of schooling and when team teaching is involved. Each team member, or year in school, will have a clear understanding of what needs to be accomplished in each class, or at each level, allowing students to progress. Those designing and planning the curriculum are expected to work backwards once an outcome has been decided upon; they must determine what knowledge and skills will be required to reach the outcome. Flexibility With a clear sense of what needs to be accomplished, instructors will be able to structure their lessons around the student’s needs. OBE does not specify a specific method of instruction, leaving instructors free to teach their students using any method. Instructors will also be able to recognize diversity among students by using various teaching and assessment techniques during their class. OBE is meant to be a student-centered learning model. Teachers are meant to guide and help the students understand the material in any way necessary, study guides, and group work are some of the methods instructors can use to facilitate students learning. Comparison OBE can be compared across different institutions. On an individual level, institutions can look at what outcomes a student has achieved to decide what level the student would be at within a new institution. On an institutional level, institutions can compare themselves, by checking to see what outcomes they have in common, and find places where they may need improvement, based on the achievement of outcomes at other institutions. The ability to compare easily across institutions allows students to move between institutions with relative ease. The institutions can compare outcomes to determine what credits to award the student. The clearly articulated outcomes should allow institutions to assess the student’s achievements rapidly, leading to increased movement of students. These outcomes also work for school to work transitions. A potential employer can look at records of the potential employee to determine what outcomes they have achieved. They can then determine if the potential employee has the skills necessary for the job. Involvement Student involvement in the classroom is a key part of OBE. Students are expected to do their own learning, so that they gain a full understanding of the material. Increased student involvement allows students to feel responsible for their own learning, and they should learn more through this individual learning. Other aspects of involvement are parental and community, through developing curriculum, or making changes to it. OBE outcomes are meant to be decided upon within a school system, or at a local level. Parents and community members are asked to give input in order to uphold the standards of education within a community and to ensure that students will be prepared for life after school. Drawbacks of OBE Definition The definitions of the outcomes decided upon are subject to interpretation by those implementing them. Across different programs or even different instructors outcomes could be interpreted differently, leading to a difference in education, even though the same outcomes were said to be achieved. By outlining specific outcomes, a holistic approach to learning is lost. Learning can find itself reduced to something that is specific, measurable, and observable. As a result, outcomes are not yet widely recognized as a valid way of conceptualizing what learning is about. Assessment problems When determining if an outcome has been achieved, assessments may become too mechanical, looking only to see if the student has acquired the knowledge. The ability to use and apply the knowledge in different ways may not be the focus of the assessment. The focus on determining if the outcome has been achieved leads to a loss of understanding and learning for students, who may never be shown how to use the knowledge they have gained. Instructors are faced with a challenge: they must learn to manage an environment that can become fundamentally different from what they are accustomed to. In regards to giving assessments, they must be willing to put in the time required to create a valid, reliable assessment that ideally would allow students to |
to return empty-handed." According to Russian historian Vladimir Petrukhin, Olga invited the Roman rite bishops because she wanted to motivate Byzantine priests to catechize the Rus' people more enthusiastically, by introducing competition. Death According to the Primary Chronicle, Olga died from illness in 969, soon after the Pechenegs' siege of the city. When Sviatoslav announced plans to move his throne to the Danube region, the ailing Olga convinced him to stay with her during her final days. Only three days later, she passed away and her family and all of Kievan Rus’ wept:Sviatoslav announced to his mother and his boyars, "I do not care to remain in Kiev, but should prefer to live in Peryaslavets on the Danube, since that is the centre of my realm, where all riches are concentrated; gold, silks, wine, and various fruits from Greece, silver and horses from Hungary and Bohemia, and from Rus' furs, wax, honey, and slaves." But Olga made reply, "You behold me in my weakness. Why do you desire to depart from me?" For she was already in precarious health. She thus remonstrated with him and begged him first to bury her and then to go wheresoever he would. Three days later Olga died. Her son wept for her with great mourning, as did likewise her grandsons and all the people. They thus carried her out, and buried her in her tomb. Olga had given command not to hold a funeral feast for her, for she had a priest who performed the last rites over the sainted Princess.Although he disapproved of his mother's Christian tradition, Sviatoslav heeded Olga's request that her priest, Gregory, conduct a Christian funeral without the ritual pagan burial feast. Her tomb remained in Kiev for over two centuries, but was destroyed by the Mongolian-Tatar armies of Batu Khan in 1240. Legacy Sainthood At the time of her death, it seemed that Olga's attempt to make Kievan Rus' a Christian territory had been a failure. Nonetheless, Olga's Christianizing mission would be brought to fruition by her grandson, Vladimir, who officially adopted Christianity in 988. The Primary Chronicle highlights Olga's holiness in contrast to the pagans around her during her life as well as the significance of her decision to convert to Christianity:Olga was the precursor of the Christian land, even as the day-spring precedes the sun and as the dawn precedes the day. For she shone like the moon by night, and she was radiant among the infidels like a pearl in the mire, since the people were soiled, and not yet purified of their sin by holy baptism. But she herself was cleansed by this sacred purification…. She was the first from Rus' to enter the kingdom of God, and the sons of Rus' thus praise her as their leader, for since her death she has interceded with God in their behalf.In 1547, nearly 600 years after her 969 death, the Russian Orthodox Church named Olga a saint. Because of her proselytizing influence, the Eastern Orthodox Church, the Ruthenian Greek Catholic Church, and the Ukrainian Greek Catholic Church call Olga by the honorific Isapóstolos, "Equal to the Apostles". She is also a saint in the Roman Catholic Church. Olga's feast day is July 11, the date of her death. In keeping with her own biography, she is the patron of widows and converts. Olga is venerated as saint in East Slavic-speaking countries where churches uses the Byzantine Rite: Eastern Orthodox Church (especially in Russian Orthodox Church), Greek Catholic Church (especially in the Ukrainian Greek Catholic Church), in churches with Byzantine Rite Lutheranism, and in the Roman Catholic Church in Russia (Latin rite).

Modern publications, on the other hand, reflect a broader interest in Olga beyond her role in expanding Christendom. Detailing her story, a 2018 article claimed she showed her countrymen how "a woman could rule with strength and decision." The Russian Primary Chronicle's claim that Olga was of Viking descent also received attention for its possible contribution to her "warrior spirit". Thomas Craughwell has commented, "If any saint [was] bad to the bone, it was Olga, princess of Kiev ... [She] took viciousness to a new level." Russian historian Boris Akunin argues though she certainly reconquered the Drevlians, only her killing of their first envoy is plausible, since Iskorosten was just two days' ride from Kiev, making it difficult to conceal the first public murder. Arts and literature In 1981 a new ballet based on Olga's life was composed to commemorate the 1500th anniversary of the city of Kyiv.

He taught her the doctrine of the church, and instructed her in prayer and fasting, in almsgiving, and in the maintenance of chastity. She bowed her head, and like a sponge absorbing water, she eagerly drank in his teachings. The Princess bowed before the Patriarch, saying, "Through thy prayers, Holy Father, may I be preserved from the crafts and assaults of the devil!" At her baptism she was christened Helena, after the ancient Empress, mother of Constantine the Great. The Patriarch then blessed her and dismissed her.While the Primary Chronicle notes that Olga was christened with the name "Helena" after the ancient Saint Helena (the mother of Constantine the Great), Jonathan Shepard argues that Olga's baptismal name comes from the contemporary emperor's wife, Helena. The observation that Olga was "worthy to reign with him in his city" suggests that the emperor was interested in marrying her. While the Chronicle explains Constantine's desire to take Olga as his wife as stemming from the fact that she was "fair of countenance and wise as well," marrying Olga could certainly have helped him gain power over Rus'. The Chronicle recounts that Olga asked the emperor to baptize her knowing that his baptismal sponsorship, by the rules of spiritual kinship, would make marriage between them a kind of spiritual incest. Though her desire to become Christian may have been genuine, this request was also a way for her to maintain political independence. After the baptism, when Constantine repeated his marriage proposal, Olga answered that she could not marry him since church law forbade a goddaughter to marry her godfather:After her baptism, the Emperor summoned Olga and made known to her that he wished her to become his wife. But she replied, "How can you marry me, after yourself baptizing me and calling me your daughter? For among Christians that is unlawful, as you yourself must know." Then the Emperor said, "Olga, you have outwitted me." He gave her many gifts of gold, silver, silks, and various vases, and dismissed her, still calling her his daughter.Francis Butler argues that the story of the proposal was a literary embellishment, describing an event that is highly unlikely to have ever actually occurred. In fact, at the time of her baptism, Constantine already had an empress. In addition to uncertainty over the truth of the Chronicle telling of events in Constantinople, there is controversy over the details of her conversion to Christianity. According to Russian sources, she was baptized in Constantinople in 957. Byzantine sources, however, indicate that she was a Christian prior to her 957 visit. It seems likely that she was baptized in Kiev around 955 and, following a second christening in Constantinople, took the Christian name Helen. Olga was not the first person from Rus' to convert from her pagan ways-- there were Christians in Igor's court who had taken oaths at the St. Elias Church in Kiev for the Rus'–Byzantine Treaty in 945--but she was the most powerful Rus' individual to undergo baptism during her life. Efforts to Christianize Kievan Rus' The Primary Chronicle reports that Olga received the Patriarch's blessing for her journey home, and that once she arrived, she unsuccessfully attempted to convert her son to Christianity:Now Olga dwelt with her son Sviatoslav, and she urged him to be baptized, but he would not listen to her suggestion, though when any man wished to be baptized, he was not hindered, but only mocked. For to the infidels, the Christian faith is foolishness. They do not comprehend it, because they walk in darkness and do not see the glory of God. Their hearts are hardened, and they can neither hear with their ears nor see with their eyes. For Solomon has said, "The deeds of the unrighteous are far from wisdom. Inasmuch as I have called you, and ye heard me not, I sharpened my words, and ye understood not. But ye have set at nought all my counsel, and would have none of my reproach. For they have hated knowledge, and the fear of Jehovah they have not chosen. They would none of my counsel, but despised all my reproof."This passage highlights the hostility towards Christianity in Kievan Rus' in the tenth century. In the Chronicle, Sviatoslav declares that his followers would "laugh" if he were to accept Christianity. While Olga tried to convince her son that his followers would follow his example if he converted, her efforts were in vain. However, her son agreed not to persecute those in his kingdom who did convert, which marked a crucial turning point for Christianity in the area. Despite the resistance of her people to Christianity, Olga built churches in Kiev, Pskov, and elsewhere. Relations with the Holy Roman Emperor Seven Latin sources document Olga's embassy to Holy Roman Emperor Otto I in 959. The continuation of Regino of Prüm mentions that the envoys requested the emperor to appoint a bishop and priests for their nation. The chronicler accuses the envoys of lies, commenting that their trick was not exposed until later. Thietmar of Merseburg says that the first archbishop of Magdeburg, Adalbert of Magdeburg, before being promoted to this high rank, was sent by Emperor Otto to the country of the Rus' (Rusciae) as a simple bishop but was expelled by pagan allies of Sviatoslav I. The same data is repeated in the annals of Quedlinburg and Hildesheim. In 2018, Russian historian and writer Boris Akunin pointed out the importance of a 2-year gap between invitation and arrival of bishops: "The failure of Olga's Byzantine trip has inflicted a severe blow to her party. The Grand Knyaginya made a second attempt to find a Christian patron, now in the West. But it seems, in the period between the sending of the embassy to Emperor Otto in 959 and the arrival of Adalbert in Kiev in 961, a bloodless coup took place. Pagan party prevailed, the young Sviatoslav pushed his mother into the background, and that's why the German bishops had to return empty-handed." According to Russian historian Vladimir Petrukhin, Olga invited the Roman rite bishops because she wanted to motivate Byzantine priests to catechize the Rus' people more enthusiastically, by introducing competition. Death According to the Primary Chronicle, Olga died from illness in 969, soon after the Pechenegs' siege of the city.

In addition, the magma chambers are thought to be much larger and deeper than the ones found on Earth. The flanks of Olympus Mons are made up of innumerable lava flows and channels. Many of the flows have levees along their margins (pictured). The cooler, outer margins of the flow solidify, leaving a central trough of molten, flowing lava. Partially collapsed lava tubes are visible as chains of pit craters, and broad lava fans formed by lava emerging from intact, subsurface tubes are also common. In places along the volcano's base, solidified lava flows can be seen spilling out into the surrounding plains, forming broad aprons, and burying the basal escarpment. Crater counts from high-resolution images taken by the Mars Express orbiter in 2004 indicate that lava flows on the northwestern flank of Olympus Mons range in age from 115 million years old (Mya) to only 2 Mya. These ages are very recent in geological terms, suggesting that the mountain may still be volcanically active, though in a very quiescent and episodic fashion. The caldera complex at the peak of the volcano is made of at least six overlapping calderas and caldera segments (pictured). Calderas are formed by roof collapse following depletion and withdrawal of the subsurface magma chamber after an eruption. Each caldera thus represents a separate pulse of volcanic activity on the mountain. The largest and oldest caldera segment appears to have formed as a single, large lava lake. Using geometric relationships of caldera dimensions from laboratory models, scientists have estimated that the magma chamber associated with the largest caldera on Olympus Mons lies at a depth of about below the caldera floor. Crater size-frequency distributions on the caldera floors indicate the calderas range in age from 350 Mya to about 150 Mya. All probably formed within 100 million years of each other. Olympus Mons is asymmetrical structurally as well as topographically. The longer, more shallow northwestern flank displays extensional features, such as large slumps and normal faults. In contrast, the volcano's steeper southeastern side has features indicating compression, including step-like terraces in the volcano's mid-flank region (interpreted as thrust faults) and a number of wrinkle ridges located at the basal escarpment. Why opposite sides of the mountain should show different styles of deformation may lie in how large shield volcanoes grow laterally and in how variations within the volcanic substrate have affected the mountain's final shape. Large shield volcanoes grow not only by adding material to their flanks as erupted lava, but also by spreading laterally at their bases. As a volcano grows in size, the stress field underneath the volcano changes from compressional to extensional. A subterranean rift may develop at the base of the volcano, causing the underlying crust to spread apart. If the volcano rests on sediments containing mechanically weak layers (e.g., beds of water-saturated clay), detachment zones (décollements) may develop in the weak layers. The extensional stresses in the detachment zones can produce giant landslides and normal faults on the volcano's flanks, leading to the formation of a basal escarpment. Further from the volcano, these detachment zones can express themselves as a succession of overlapping, gravity driven thrust faults. This mechanism has long been cited as an explanation of the Olympus Mons aureole deposits (discussed below). Olympus Mons lies at the edge of the Tharsis bulge, an ancient vast volcanic plateau likely formed by the end of the Noachian Period. During the Hesperian, when Olympus Mons began to form, the volcano was located on a shallow slope that descended from the high in Tharsis into the northern lowland basins. Over time, these basins received large volumes of sediment eroded from Tharsis and the southern highlands. The sediments likely contained abundant Noachian-aged phyllosilicates (clays) formed during an early period on Mars when surface water was abundant, and were thickest in the northwest where basin depth was greatest. As the volcano grew through lateral spreading, low-friction detachment zones preferentially developed in the thicker sediment layers to the northwest, creating the basal escarpment and widespread lobes of aureole material (Lycus Sulci). Spreading also occurred to the southeast; however, it was more constrained in that direction by the Tharsis rise, which presented a higher-friction zone at the volcano's base. Friction was higher in that direction because the sediments were thinner and probably consisted of coarser grained material resistant to sliding. The competent and rugged basement rocks of Tharsis acted as an additional source of friction. This inhibition of southeasterly basal spreading in Olympus Mons could account for the structural and topographic asymmetry of the mountain. Numerical models of particle dynamics involving lateral differences in friction along the base of Olympus Mons have been shown to reproduce the volcano's present shape and asymmetry fairly well. It has been speculated that the detachment along the weak layers was aided by the presence of high-pressure water in the sediment pore spaces, which would have interesting astrobiological implications. If water-saturated zones still exist in sediments under the volcano, they would likely have been kept warm by a high geothermal gradient and residual heat from the volcano's magma chamber. Potential springs or seeps around the volcano would offer exciting possibilities for detecting microbial life. Early observations and naming Olympus Mons and a few other volcanoes in the Tharsis region stand high enough to reach above the frequent Martian dust-storms recorded by telescopic observers as early as the 19th century. The astronomer Patrick Moore pointed out that Schiaparelli (1835–1910) "had found that his Nodus Gordis and Olympic Snow [Nix Olympica] were almost the only features to be seen" during dust storms, and "guessed correctly that they must be high". The Mariner 9 spacecraft arrived in orbit around Mars in 1971 during a global dust-storm. The first objects to become visible as the dust began to settle, the tops of the Tharsis volcanoes, demonstrated that the altitude of these features greatly exceeded that of any mountain found on Earth, as astronomers expected. Observations of the planet from Mariner 9 confirmed that Nix Olympica was a volcano. Ultimately, astronomers adopted the name Olympus Mons for the albedo | Tharsis quadrangle (MC-9). Two impact craters on Olympus Mons have been assigned provisional names by the International Astronomical Union. They are the Karzok crater () and the Pangboche crater (). The craters are notable for being two of several suspected source areas for shergottites, the most abundant class of Martian meteorites. Description As a shield volcano, Olympus Mons resembles the shape of the large volcanoes making up the Hawaiian Islands. The edifice is about wide. Because the mountain is so large, with complex structure at its edges, allocating a height to it is difficult. Olympus Mons stands above the Mars global datum, and its local relief, from the foot of the cliffs which form its northwest margin to its peak, is over (a little over twice the height of Mauna Kea as measured from its base on the ocean floor). The total elevation change from the plains of Amazonis Planitia, over to the northwest, to the summit approaches . The summit of the mountain has six nested calderas (collapsed craters) forming an irregular depression × across and up to deep. The volcano's outer edge consists of an escarpment, or cliff, up to tall (although obscured by lava flows in places), a feature unique among the shield volcanoes of Mars, which may have been created by enormous flank landslides. Olympus Mons covers an area of about , which is approximately the size of Italy or the Philippines, and it is supported by a thick lithosphere. The extraordinary size of Olympus Mons is likely because Mars lacks mobile tectonic plates. Unlike on Earth, the crust of Mars remains fixed over a stationary hotspot, and a volcano can continue to discharge lava until it reaches an enormous height. Being a shield volcano, Olympus Mons has a very gently sloping profile. The average slope on the volcano's flanks is only 5%. Slopes are steepest near the middle part of the flanks and grow shallower toward the base, giving the flanks a concave upward profile. Its flanks are shallower and extend farther from the summit in the northwestern direction than they do to the southeast. The volcano's shape and profile have been likened to a "circus tent" held up by a single pole that is shifted off center. Due to the size and shallow slopes of Olympus Mons, an observer standing on the Martian surface would be unable to view the entire profile of the volcano, even from a great distance. The curvature of the planet and the volcano itself would obscure such a synoptic view. Similarly, an observer near the summit would be unaware of standing on a very high mountain, as the slope of the volcano would extend far beyond the horizon, a mere 3 kilometers away. The typical atmospheric pressure at the top of Olympus Mons is 72 pascals, about 12% of the average Martian surface pressure of 600 pascals. Both are exceedingly low by terrestrial standards; by comparison, the atmospheric pressure at the summit of Mount Everest is 32,000 pascals, or about 32% of Earth's sea level pressure. Even so, high-altitude orographic clouds frequently drift over the Olympus Mons summit, and airborne Martian dust is still present. Although the average Martian surface atmospheric pressure is less than one percent of Earth's, the much lower gravity of Mars increases the atmosphere's scale height; in other words, Mars's atmosphere is expansive and does not drop off in density with height as sharply as Earth's.

OODBMS and the programming language will use the same model of representation. Relational DBMS projects, by way of contrast, maintain a clearer division between the database model and the application. As the usage of web-based technology increases with the implementation of Intranets and extranets, companies have a vested interest in OODBMSs to display their complex data. Using a DBMS that has been specifically designed to store data as objects gives an advantage to those companies that are geared towards multimedia presentation or organizations that utilize computer-aided design (CAD). Some object-oriented databases are designed to work well with object-oriented programming languages such as Delphi, Ruby, Python, JavaScript, Perl, Java, C#, Visual Basic .NET, C++, Objective-C and Smalltalk; others such as JADE have their own programming languages. OODBMSs use exactly the same model as object-oriented programming languages. History Object database management systems grew out of research during the early to mid-1970s into having intrinsic database management support for graph-structured objects. The term "object-oriented database system" first appeared around 1985. Notable research projects included Encore-Ob/Server (Brown University), EXODUS (University of Wisconsin–Madison), IRIS (Hewlett-Packard), ODE (Bell Labs), ORION (Microelectronics and Computer Technology Corporation or MCC), Vodak (GMD-IPSI), and Zeitgeist (Texas Instruments). The ORION project had more published papers than any of the other efforts. Won Kim of MCC compiled the best of those papers in a book published by The MIT Press. Early commercial products included Gemstone (Servio Logic, name changed to GemStone Systems), Gbase (Graphael), and Vbase (Ontologic). Additional commercial products entered the market in the late 1980s through the mid 1990s. These included ITASCA (Itasca Systems), Jasmine (Fujitsu, marketed by Computer Associates), Matisse (Matisse Software), Objectivity/DB (Objectivity, Inc.), ObjectStore (Progress Software, acquired from eXcelon which was originally Object Design, Incorporated), ONTOS (Ontos, Inc., name changed from Ontologic), O2 (O2 Technology, merged with several companies, acquired by Informix, which was in turn acquired by IBM), POET (now FastObjects from Versant which acquired Poet Software), Versant Object Database (Versant Corporation), VOSS (Logic Arts) and JADE (Jade Software Corporation). Some of these products remain on the market and have been joined by new open source and commercial products such as InterSystems Caché. Object database management systems added the concept of persistence to object programming languages. The early commercial products were integrated with various languages: GemStone (Smalltalk), Gbase (LISP), Vbase (COP) and VOSS (Virtual Object Storage System for Smalltalk). For much of the 1990s, C++ dominated the commercial object database management market. Vendors added Java in the late 1990s and more recently, C#. Starting in 2004, object databases have seen a second growth period when open source object databases emerged that were widely affordable and easy to use, because they are entirely written in OOP languages like Smalltalk, Java, or C#, such as Versant's db4o (db4objects), DTS/S1 from Obsidian Dynamics and Perst (McObject), available under dual open source and commercial licensing.'''

Multimedia applications are facilitated because the class methods associated with the data are responsible for its correct interpretation. Many object databases, for example Gemstone or VOSS, offer support for versioning. An object can be viewed as the set of all its versions. Also, object versions can be treated as objects in their own right. Some object databases also provide systematic support for triggers and constraints which are the basis of active databases. The efficiency of such a database is also greatly improved in areas which demand massive amounts of data about one item. For example, a banking institution could get the user's account information and provide them efficiently with extensive information such as transactions, account information entries etc. Standards The Object Data Management Group was a consortium of object database and object–relational mapping vendors, members of the academic community, and interested parties. Its goal was to create a set of specifications that would allow for portable applications that store objects in database management systems. It published several versions of its specification. The last release was ODMG 3.0. By 2001, most of the major object database and object–relational mapping vendors claimed conformance to the ODMG Java Language Binding. Compliance to the other components of the specification was mixed. In 2001, the ODMG Java Language Binding was submitted to the Java Community Process as a basis for the Java Data Objects specification. The ODMG member companies then decided to concentrate their efforts on the Java Data Objects specification. As a result, the ODMG disbanded in 2001. Many object database ideas were also absorbed into SQL:1999 and have been implemented in varying degrees in object–relational database products. In 2005 Cook, Rai, and Rosenberger proposed to drop all standardization efforts to introduce additional object-oriented query APIs but rather use the OO programming language itself, i.e., Java and .NET, to express queries. As a result, Native Queries emerged. Similarly, Microsoft |
slave wears a tunic and is chained to a wall. Following her torture session, the Slave Girl breaks free and becomes the fifth dancer of the night. Later, the Black Ghoul exhibits a fascination with Shirley and scratches a mark on her. She draws a knife and seems about to kill Shirley, when the Emperor decides it is not yet time for the intruders to properly join them. The female ghoul reluctantly obeys. The Emperor is puzzled when a human skull appears instead of the next dancer. The Black Ghoul explains it is the symbol of the sixth dancer, who loved bullfighting and matadors. She used to dance over their demise, and now it is time to dance over her own. The dancer of apparent Spanish/Mexican heritage (Stephanie Jones) appears to perform. The Emperor and Ghoul briefly discuss the past of the dancer, who came to them on the Day of the Dead. The seventh dancer appears dressed in Polynesian garments. The Black Ghoul describes her as a worshiper of snakes, smoke, and flames. A rattlesnake is depicted along with her dance. The camera shifts to the mummy and the werewolf. The mummy voices his dislike of snakes and recalls the death of Cleopatra. He informs his companion that ancient Egypt had many snakes and they were the stuff of nightmares. The Emperor next expresses his boredom and demands "unusual" entertainment, while the Black Ghoul notes that the night is almost over. She reminds her superior that they will be gone at the first sight of the morning sun. They proceed to argue over the fate of Shirley. The argument ends with the introduction of the eighth dancer, a woman who murdered her husband on their wedding night. She dances with the skeleton of her spouse. The argument over Shirley then resumes, as the Ghoul claims her for her own. The Emperor feels the need to assert his own authority over the Black Ghoul. The ninth dancer was a zombie in life and remains zombie-like in death. The tenth and final dancer is introduced as one who died for feathers, fur, and fluff. She starts her dance in clothing matching this style. When the final dance ends, the Emperor finally offers Shirley to the Ghoul. The Ghoul briefly dances herself as she prepares to claim her prize, but dawn arrives and with it, sunlight. The Emperor and all his undead are reduced to bones.

patented it in 1902. The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production. Historically and practically, the Ostwald process is closely associated with the Haber process, which provides the requisite raw material, ammonia (NH3). Description Stage 1 Ammonia is converted to nitric acid in 2 stages. It is oxidized by heating with oxygen in the presence of a catalyst such as platinum with 10% rhodium, platinum metal on fused silica wool, copper or nickel, to form nitric oxide (nitrogen(II) oxide) and water (as steam). This reaction is strongly exothermic, making it a useful heat source once initiated: 4 NH3 (g) + 5 O2 (g) -> 4 NO (g) + 6 H2O (g) (ΔH = −905.2 kJ/mol) Stage 2 Stage two encompasses two reactions and is carried out in an absorption apparatus containing water. Initially nitric oxide is oxidized again to yield nitrogen dioxide (nitrogen(IV) oxide). This gas is then readily absorbed by the water, yielding the desired product (nitric acid, albeit in a dilute form), while reducing a portion of it back to nitric oxide: 2 NO (g) + O2 (g) -> 2 NO2 (g) (ΔH = −114 kJ/mol) 3 NO2 (g) + H2O (l) -> 2 HNO3 (aq) + NO (g) (ΔH = −117 kJ/mol) The NO is recycled, and the acid is concentrated to the | into consideration is a side-reaction in the first step that reverts the nitric oxide back to nitrogen: 4 NH3 + 6 NO -> 5 N2 + 6 H2O This is a secondary reaction that is minimised by reducing the time the gas mixtures are in contact with the catalyst. Overall reaction The overall reaction is the sum of the first equation, 3 times the second equation, and 2 times the last equation; all divided by 2: 2 NH3 (g) + 4 O2 (g) + H2O (l) -> 3 H2O (g) + 2 HNO3 (aq) (ΔH = −740.6 kJ/mol) Alternatively, if the last step is carried out in air, the overall reaction is the sum of equation 1, 2 times the equation 2, and equation 4; all divided by 2.

July 2014, academics at Newcastle University, UK and the Newcastle Electromagnetics Interest Group founded the Heaviside Memorial Project in a bid to fully restore the monument through public subscription. The restored memorial was ceremonially unveiled on 30 August 2014 by Alan Heather, a distant relative of Heaviside. The unveiling was attended by the Mayor of Torbay, the Member of Parliament (MP) for Torbay, an ex-curator of the Science Museum (representing the Institution of Engineering and Technology), the Chairman of the Torbay Civic Society, and delegates from Newcastle University. The Heaviside Collection 1872–1923 A collection of Heaviside's notebooks, papers, correspondence, notes and annotated pamphlets on telegraphy is held at the Institution of Engineering and Technology (IET) Archive Centre. Innovations and discoveries Heaviside did much to develop and advocate vector methods and vector calculus. Maxwell's formulation of electromagnetism consisted of 20 equations in 20 variables. Heaviside employed the curl and divergence operators of the vector calculus to reformulate 12 of these 20 equations into four equations in four variables (), the form by which they have been known ever since (see Maxwell's equations). Less well known is that Heaviside's equations and Maxwell's are not exactly the same, and in fact it is easier to modify the former to make them compatible with quantum physics. The possibility of gravitational waves was also discussed by Heaviside using the analogy between the inverse-square law in gravitation and electricity. With quaternion multiplication, the square of a vector is a negative quantity, much to Heaviside's displeasure. As he advocated abolishing this negativity, he has been credited by C. J. Joly with developing hyperbolic quaternions, though in fact that mathematical structure was largely the work of Alexander Macfarlane. He invented the Heaviside step function, using it to calculate the current when an electric circuit is switched on. He was the first to use the unit impulse function now usually known as the Dirac delta function. He invented his operational calculus method for solving linear differential equations. This resembles the currently used Laplace transform method based on the "Bromwich integral" named after Bromwich who devised a rigorous mathematical justification for Heaviside's operator method using contour integration. Heaviside was familiar with the Laplace transform method but considered his own method more direct. Heaviside developed the transmission line theory (also known as the "telegrapher's equations"), which had the effect of increasing the transmission rate over transatlantic cables by a factor of ten. It originally took ten minutes to transmit each character, and this immediately improved to one character per minute. Closely related to this was his discovery that telephone transmission could be greatly improved by placing electrical inductance in series with the cable. Heaviside also independently discovered the Poynting vector. Heaviside advanced the idea that the Earth's uppermost atmosphere contained an ionized layer known as the ionosphere; in this regard, he predicted the existence of what later was dubbed the Kennelly–Heaviside layer. In 1947 Edward Victor Appleton received the Nobel Prize in Physics for proving that this layer really existed. Electromagnetic terms Heaviside coined the following terms of art in electromagnetic theory: admittance (reciprocal of impedance) (December 1887); elastance (reciprocal of permittance, reciprocal of capacitance) (1886); conductance (real part of admittance, reciprocal of resistance) (September 1885); electret for the electric analogue of a permanent magnet, or, in other words, any substance that exhibits a quasi-permanent electric polarization (e.g. ferroelectric); impedance (July 1886); inductance (February 1886); permeability (September 1885); permittance (now called capacitance) and permittivity (June 1887); reluctance (May 1888); Heaviside is sometimes also credited with coining susceptance (the imaginary part of admittance, reciprocal of reactance), but this is actually due to Charles Proteus Steinmetz.

He famously said, "Mathematics is an experimental science, and definitions do not come first, but later on. They make themselves, when the nature of the subject has developed itself." On another occasion he asked somewhat more defensively, "Shall I refuse my dinner because I do not fully understand the process of digestion?" In 1887, Heaviside worked with his brother Arthur on a paper entitled "The Bridge System of Telephony". However the paper was blocked by Arthur's superior, William Henry Preece of the Post Office, because part of the proposal was that loading coils (inductors) should be added to telephone and telegraph lines to increase their self-induction and correct the distortion which they suffered. Preece had recently declared self-inductance to be the great enemy of clear transmission. Heaviside was also convinced that Preece was behind the sacking of the editor of The Electrician which brought his long-running series of articles to a halt (until 1891). There was a long history of animosity between Preece and Heaviside. Heaviside considered Preece to be mathematically incompetent, an assessment supported by the biographer Paul J. Nahin: "Preece was a powerful government official, enormously ambitious, and in some remarkable ways, an utter blockhead." Preece's motivations in suppressing Heaviside's work were more to do with protecting Preece's own reputation and avoiding having to admit error than any perceived faults in Heaviside's work. The importance of Heaviside's work remained undiscovered for some time after publication in The Electrician, and so its rights lay in the public domain. In 1897, AT&T employed one of its own scientists, George A. Campbell, and an external investigator Michael I. Pupin to find some respect in which Heaviside's work was incomplete or incorrect. Campbell and Pupin extended Heaviside's work, and AT&T filed for patents covering not only their research, but also the technical method of constructing the coils previously invented by Heaviside. AT&T later offered Heaviside money in exchange for his rights; it is possible that the Bell engineers' respect for Heaviside influenced this offer. However, Heaviside refused the offer, declining to accept any money unless the company were to give him full recognition. Heaviside was chronically poor, making his refusal of the offer even more striking. But this setback had the effect of turning Heaviside's attention towards electromagnetic radiation, and in two papers of 1888 and 1889, he calculated the deformations of electric and magnetic fields surrounding a moving charge, as well as the effects of it entering a denser medium. This included a prediction of what is now known as Cherenkov radiation, and inspired his friend George FitzGerald to suggest what now is known as the Lorentz–FitzGerald contraction. In 1889, Heaviside first published a correct derivation of the magnetic force on a moving charged particle, which is the magnetic component of what is now called the Lorentz force. In the late 1880s and early 1890s, Heaviside worked on the concept of electromagnetic mass. Heaviside treated this as material mass, capable of producing the same effects. Wilhelm Wien later verified Heaviside's expression (for low velocities). In 1891 the British Royal Society recognized Heaviside's contributions to the mathematical description of electromagnetic phenomena by naming him a Fellow of the Royal Society, and the following year devoting more than fifty pages of the Philosophical Transactions of the Society to his vector methods and electromagnetic theory. In 1905 Heaviside was given an honorary doctorate by the University of Göttingen. Later years and views In 1896, FitzGerald and John Perry obtained a civil list pension of £120 per year for Heaviside, who was now living in Devon, and persuaded him to accept it, after he had rejected other charitable offers from the Royal Society. In 1902, Heaviside proposed the existence of what is now known as the Kennelly–Heaviside layer of the ionosphere. Heaviside's proposal included means by which radio signals are transmitted around the Earth's curvature. The existence of the ionosphere was confirmed in 1923. The predictions by Heaviside, combined with Planck's radiation theory, probably discouraged further attempts to detect radio waves from the Sun and other astronomical objects. For whatever reason, there seem to have been no attempts for 30 years, until Jansky's development of radio astronomy in 1932. Heaviside was an opponent of Albert Einstein's theory of relativity. Mathematician Howard Eves has commented that Heaviside "was the only first-rate physicist at the time to impugn Einstein, and his invectives against relativity theory often bordered on the absurd". In later years his behavior became quite eccentric. According to associate B.A. Behrend, he became a recluse who was so averse to meeting people that he delivered the manuscripts of his Electrician papers to a grocery store, where the editors picked them up. Though he had been an active cyclist in his youth, his health seriously declined in his sixth decade. During this time Heaviside would sign letters with the initials "W.O.R.M." after his name. Heaviside also reportedly started painting his fingernails pink and had granite blocks moved into his house for furniture. In 1922, he became the first recipient of the Faraday Medal, which was established that year. On Heaviside's religious views, he was a Unitarian, but not religious. He was even said to have made fun of people who put their faith in a supreme being. Heaviside died on 3 February 1925, at Torquay in Devon after falling from a ladder, and is buried near the eastern corner of Paignton cemetery. He is buried with his father, Thomas Heaviside (1813–1896), and his mother, Rachel Elizabeth Heaviside. The gravestone was cleaned thanks to an anonymous donor sometime in 2005. He was always held in high regard by most electrical engineers, particularly after his correction to Kelvin's transmission line analysis was vindicated, but most of his wider recognition was gained posthumously. Heaviside Memorial Project In July 2014, academics at Newcastle University, UK and the Newcastle Electromagnetics Interest Group founded the Heaviside Memorial Project in a bid to fully restore the monument through public subscription. The restored memorial was ceremonially unveiled on 30 August 2014 by Alan Heather, a distant relative of Heaviside. The unveiling was attended by the Mayor of Torbay, the Member of Parliament |
to a new place. At the end of their journey they discover the Mulekite people whose ancestors had also come from Jerusalem, but after it was attacked by the Babylonians. These people, however, did not bring religious or historical records with them which had two results—they had lost their religion, and they were unable to preserve their language from generation to generation. These people are known as the people of Zarahemla (the name of their then current king and also the name given to the land). Mosiah arranges for the people of Zarahemla to be taught the Nephite language, and Zarahemla is able to recount to him their oral history. The two groups of people united themselves with Mosiah as their king, and they are all known as Nephites. The first mention of the Jaredites is found here as well. A large stone is found with writing on it. Mosiah is able to "interpret the engravings by the gift and power of God." It tells of a man named Coriantumr and the downfall of his people. Their history is recounted more fully in the Book of Ether. Mosiah, the king dies and his son, Benjamin, becomes king. There is a war between the Nephites led by Benjamin and the Lamanites, which by this time is nothing new. It is apparent that many of the Nephites were reluctant to leave their long-time homeland.

At the time Amaleki stops writing, he has not received word of them, including his brother who is among them. Amaleki closes with some words about Christ, asserting that his words are true and that it is his intent to help others come unto Christ.

the International Day for the Preservation of the Ozone Layer. Venus also has a thin ozone layer at an altitude of 100 kilometers above the planet's surface. Sources The photochemical mechanisms that give rise to the ozone layer were discovered by the British physicist Sydney Chapman in 1930. Ozone in the Earth's stratosphere is created by ultraviolet light striking ordinary oxygen molecules containing two oxygen atoms (O2), splitting them into individual oxygen atoms (atomic oxygen); the atomic oxygen then combines with unbroken O2 to create ozone, O3. The ozone molecule is unstable (although, in the stratosphere, long-lived) and when ultraviolet light hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle. Chemically, this can be described as: O2{} + \mathit{h}\nu_{uv} -> 2O O + O2 <-> O3 About 90 percent of the ozone in the atmosphere is contained in the stratosphere. Ozone concentrations are greatest between about , where they range from about 2 to 8 parts per million. If all of the ozone were compressed to the pressure of the air at sea level, it would be only thick. Ultraviolet light Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation coming from the Sun. Extremely short or vacuum UV (10–100 nm) is screened out by nitrogen. UV radiation capable of penetrating nitrogen is divided into three categories, based on its wavelength; these are referred to as UV-A (400–315 nm), UV-B (315–280 nm), and UV-C (280–100 nm). UV-C, which is very harmful to all living things, is entirely screened out by a combination of dioxygen (< 200 nm) and ozone (> about 200 nm) by around altitude. UV-B radiation can be harmful to the skin and is the main cause of sunburn; excessive exposure can also cause cataracts, immune system suppression, and genetic damage, resulting in problems such as skin cancer. The ozone layer (which absorbs from about 200 nm to 310 nm with a maximal absorption at about 250 nm) is very effective at screening out UV-B; for radiation with a wavelength of 290 nm, the intensity at the top of the atmosphere is 350 million times stronger than at the Earth's surface. Nevertheless, some UV-B, particularly at its longest wavelengths, reaches the surface, and is important for the skin's production of vitamin D. Ozone is transparent to most UV-A, so most of this longer-wavelength UV radiation reaches the surface, and it constitutes most of the UV reaching the Earth. This type of UV radiation is significantly less harmful to DNA, although it may still potentially cause physical damage, premature aging of the skin, indirect genetic damage, and skin cancer. Distribution in the stratosphere The thickness of the ozone layer varies worldwide and is generally thinner near the equator and thicker near the poles. Thickness refers to how much ozone is in a column over a given area and varies from season to season. The reasons for these variations are due to atmospheric circulation patterns and solar intensity. The majority of ozone is produced over the tropics and is transported towards the poles by stratospheric wind patterns. In the northern hemisphere these patterns, known as the Brewer-Dobson circulation, make the ozone layer thickest in the spring and thinnest in the fall. When ozone is produced by solar UV radiation in the tropics, it is done so by circulation lifting ozone-poor air out of the troposphere and into the stratosphere where the sun photolyzes oxygen molecules and turns them into ozone. Then, the ozone-rich air is carried to higher latitudes and drops into lower layers of the atmosphere. Research has found that the ozone levels in the United States are highest in the spring months of April and May and lowest in October. While the total amount of ozone increases moving from the tropics to higher latitudes, the concentrations are greater in high northern latitudes than in high southern latitudes, with spring ozone columns in high northern latitudes occasionally exceeding 600 DU and averaging 450 DU whereas 400 DU constituted a usual maximum in the Antarctic before anthropogenic ozone depletion. This difference occurred naturally because of the weaker polar vortex and stronger Brewer-Dobson circulation in the northern hemisphere owing to that hemisphere’s large mountain ranges and greater contrasts between land and ocean temperatures. The difference between high northern and southern latitudes has increased since the 1970s due to the ozone hole phenomenon. The highest amounts of ozone are found over the Arctic during the spring months of March and April, but the Antarctic has the lowest amounts of ozone during the summer months of September and October, Depletion The ozone layer can be depleted by free radical catalysts, including nitric oxide (NO), nitrous oxide (N2O), hydroxyl (OH), atomic chlorine (Cl), and atomic bromine (Br). While there are natural sources for all of these species, the concentrations of chlorine and bromine increased markedly in recent decades because of the release of large quantities of man-made organohalogen compounds, especially chlorofluorocarbons (CFCs) and bromofluorocarbons. These highly stable compounds are capable of surviving the rise to the stratosphere, where Cl and Br radicals are liberated by the action of ultraviolet light. Each radical is then free to initiate and catalyze a chain reaction capable of breaking down over 100,000 ozone molecules. By 2009, nitrous oxide was the largest ozone-depleting substance (ODS) emitted through human activities. The breakdown of ozone in the stratosphere results in reduced absorption of ultraviolet radiation. Consequently, unabsorbed and dangerous ultraviolet radiation is able to reach the Earth's surface at a higher intensity. Ozone levels have dropped by a worldwide average of about 4 percent since the late 1970s. For approximately 5 percent of the Earth's surface, around the north and south poles, much larger seasonal declines have been seen, and are described as "ozone holes". The discovery of the annual depletion of ozone above the Antarctic was first announced | hits ozone it splits into a molecule of O2 and an individual atom of oxygen, a continuing process called the ozone-oxygen cycle.

staffer Bill Stephney following the Howard Beach racial incident, Bernhard Goetz, and the death of Michael Stewart: "The Black man is definitely the public enemy." Public Enemy started out as opening act for the Beastie Boys during the latter's Licensed to Ill popularity, and in 1987 released their debut album Yo! Bum Rush the Show. 1987–1993: Mainstream success The group's debut album, Yo! Bum Rush the Show, was released in 1987 to critical acclaim. In October 1987, music critic Simon Reynolds dubbed Public Enemy "a superlative rock band". They released their second album, It Takes a Nation of Millions to Hold Us Back, in 1988, which performed better in the charts than their previous release, and included the hit single "Don't Believe the Hype" in addition to "Bring the Noise". It was the first hip hop album to be voted album of the year in The Village Voices influential Pazz & Jop critics' poll. In 1989, the group returned to the studio to record their third album, Fear of a Black Planet, which continued their politically charged themes. The album was supposed to be released in late 1989, but was pushed back to April 1990. It was the most successful of any of their albums and, in 2005, was selected for preservation in the National Recording Registry. It included the singles "Welcome to the Terrordome", written after the band was criticized by Jews for Professor Griff's anti-semitic comments, "911 Is a Joke", which criticized emergency response units for taking longer to arrive at emergencies in the black community than those in the white community, and "Fight the Power". "Fight the Power" is regarded as one of the most popular and influential songs in hip hop history. It was the theme song of Spike Lee's Do the Right Thing. The group's fourth album, Apocalypse 91... The Enemy Strikes Black, continued this trend, with songs like "Can't Truss It", which addressed the history of slavery and how the black community can fight back against oppression; "I Don't Wanna be Called Yo Nigga", a track that takes issue with the use of the word nigga outside of its original derogatory context. The album also included the controversial song and video "By the Time I Get to Arizona", which chronicled the black community's frustration that some US states did not recognize Martin Luther King Jr.'s birthday as a national holiday. The video featured members of Public Enemy taking out their frustrations on politicians in the states not recognizing the holiday. In 1992, the group was one of the first rap acts to perform at the Reading Festival in the UK, headlining the second day of the three-day festival. 1994–2019: Later years and member changes After a 1994 motorcycle accident shattered his left leg and kept him in the hospital for a full month, Terminator X relocated to his 15-acre farm in Vance County, North Carolina. By 1998, he was ready to retire from the group and focus full-time on raising African black ostriches on his farm. In late 1998, the group started looking for Terminator X's permanent replacement. Following several months of searching for a DJ, Professor Griff saw DJ Lord at a Vestax Battle and approached him about becoming the DJ for Public Enemy. DJ Lord joined as the group's full-time DJ just in time for Public Enemy's 40th World Tour. Since 1999, he has been the official DJ for Public Enemy on albums and world tours while winning numerous turntablist competitions, including multiple DMC finals. In 2007, the group released an album entitled How You Sell Soul to a Soulless People Who Sold Their Soul?. Public Enemy's single from the album was "Harder Than You Think". Four years after How You Sell Soul ... , in January 2011, Public Enemy released the album Beats and Places, a compilation of remixes and "lost" tracks. On July 13, 2012, Most of My Heroes Still Don't Appear on No Stamp was released and was exclusively available on iTunes. In July 2012, on UK television an advert for the London 2012 Summer Paralympics featured a short remix of the song "Harder Than You Think". The advert caused the song to reach No. 4 in the UK Singles Chart on September 2, 2012. On July 30, 2012, Public Enemy performed a free concert with Salt-N-Pepa and Kid 'n Play at Wingate Park in Brooklyn, New York as part of the Martin Luther King Jr. Concert Series. On August 26, 2012, Public Enemy performed at South West Four music festival in Clapham Common in London. On October 1, 2012 The Evil Empire of Everything was released. On June 29, 2013, they performed at Glastonbury Festival 2013. On September 14, 2013, they performed at Riot Fest & Carnival 2013 in Chicago, Illinois. On September 20, 2013, they performed at Riot Fest & Side Show in Byers, Colorado. In 2014, Chuck D launched PE 2.0 with Oakland rapper Jahi as a spiritual successor and "next generation" of Public Enemy. Jahi met Chuck D backstage during a soundcheck at the 1999 Rock & Roll Hall of Fame and later appeared as a support act on Public Enemy's 20th Anniversary Tour in 2007. PE 2.0's task is twofold, Jahi says, to "take select songs from the PE catalog and cover or revisit them" as well as new material with members of the original Public Enemy including DJ Lord, Davy DMX, Professor Griff and Chuck D. PE 2.0's first album People Get Ready was released on October 7, 2014. InsPirEd PE 2.0's second album and part two of a proposed trilogy was released a year later on October 11, 2015. Man Plans God Laughs, Public Enemy's thirteenth album, was released in July 2015. On June 29, 2017, Public Enemy released their fourteenth album, Nothing Is Quick in the Desert. The album was available for free download through Bandcamp until July 4, 2017. 2020–present: Controversy, Public Enemy Radio, and return to Def Jam In late February 2020, it was announced that Public Enemy (billed as Public Enemy Radio) would perform at a campaign rally in Los Angeles on March 1, 2020, for Bernie Sanders, who was campaigning to be the nominee of the Democratic Party in the 2020 presidential election. Days following the announcement, Flavor Flav's lawyer Matthew Friedman issued a cease-and desist letter asking the campaign to not use the group's name or logo, stating: "While Chuck is certainly free to express his political views as he sees fit — his voice alone does not speak for Public Enemy". Chuck D responded to the statement by saying: "Flavor chooses to dance for his money and not do benevolent work like this. He has a year to get his act together and get himself straight or he's out". A lawyer for Chuck D added: "Chuck could perform as Public Enemy if he ever wanted to; he is the sole owner of the Public Enemy trademark. He originally drew the logo himself in the mid-80s, is also the creative visionary and the group's primary songwriter, having written Flavor's most memorable lines". On March 1, 2020, prior to the group's performance at the Sanders rally, Chuck D, DJ Lord, Jahi, James Bomb and Pop Diesel issued a joint statement announcing that Flavor Flav had been fired from the group, stating: "Public Enemy and Public Enemy Radio will be moving forward without Flavor Flav. We thank him for his years of service and wish him well". The statement also claimed: "Flavor Flav has been on suspension since 2016 when he was MIA from the Harry Belafonte benefit in Atlanta, Georgia. That was the last straw for the group. He had previously missed numerous live gigs from Glastonbury to Canada, album recording sessions and photo shoots. He always chose to party over work". On March 2, 2020, it was announced that Public Enemy Radio would be releasing the album Loud Is Not Enough which was due for release in April 2020. The album was to feature the lineup of Chuck D, DJ Lord, Jahi and the S1Ws and according to a statement from the group it will be "taking it back to hip hop’s original DJ-and-turntablist foundation". On April 1, 2020, it was revealed Flavor Flav's firing was a publicity stunt to gain attention and provide a commentary on disinformation, with Reuters claiming that Chuck D and Flavor Flav "concocted a fake split to grab attention and highlight media bias towards reporting bad news about hip hop". In an interview with rapper Talib Kweli, Chuck D stated that the stunt was inspired by Orson Welles' 1938 radio drama "The War of the Worlds". In response, Flavor Flav tweeted: "I am not a part of your hoax" and: "There are more serious things in the world right now than April Fool's jokes and dropping records. The world needs better than this,,,you say we are leaders so act like one". On June 19, 2020, Public Enemy (with Flavor Flav), released the single and music video for their anti-Donald Trump song, "State of the Union (STFU)". Chuck D stated, "Our collective voices keep getting louder. The rest of the planet is on our side. But it's not enough to talk about change. You have to show up and demand change. Folks gotta vote like their lives depend on it, cause it does". In 2020, the group returned to Def Jam and released their thirteenth studio album, What You Gonna Do When the Grid Goes Down?, on September 25, 2020. Legacy Public Enemy made contributions to the hip-hop world with sonic experimentation as well as political and cultural consciousness, which infused itself into skilled and poetic rhymes. Critic Stephen Thomas Erlewine wrote that "PE brought in elements of free jazz, hard funk, even musique concrète, via [its] producing team the Bomb Squad, creating a dense, ferocious sound unlike anything that came before." Public Enemy held a strong, pro-black, political stance. Before PE, politically motivated hip-hop was defined by a few tracks by Ice-T, Grandmaster Flash and the Furious Five, Kurtis Blow and Boogie Down Productions. Other politically motivated opinions were shared by prototypical artists Gil Scott-Heron and the Last Poets. PE was a revolutionary hip-hop act whose entire image rested on a specified political stance. With the successes of Public Enemy, many hip-hop artists began to celebrate Afrocentric themes, such as Kool Moe Dee, Gang Starr, X Clan, Eric B. & Rakim, Queen Latifah, the Jungle Brothers, and A Tribe Called Quest. Public Enemy was one of the first hip-hop groups to do well internationally. PE changed the Internet's music distribution capability by being one of the first groups to release MP3-only albums, a format virtually unknown at the time. Public Enemy helped to create and define "rap metal" by collaborating with Living Colour in 1988 ("Funny Vibe"), with Sonic Youth on the 1990 song "Kool Thing", and with New York thrash metal outfit Anthrax in 1991. The single "Bring the Noise" was a mix of semi-militant black power lyrics, grinding guitars, and sporadic humor. The two bands, cemented by a mutual respect and the personal friendship between Chuck D and Anthrax's Scott Ian, introduced a hitherto alien genre to rock fans, and the two seemingly disparate groups toured together. Flavor Flav's pronouncement on stage that "They said this tour would never happen" (as heard on Anthrax's Live: The Island Years CD) has become a legendary comment in both rock and hip-hop circles. Metal guitarist Vernon Reid (of Living Colour) contributed to Public Enemy's recordings, and PE sampled Slayer's "Angel of Death" half-time riff on "She Watch Channel Zero?!" Members of the Bomb Squad produced or remixed works for other acts, like Bell Biv DeVoe, Ice Cube, Vanessa Williams, Sinéad O'Connor, Blue Magic, Peter Gabriel, L.L. Cool J, Paula Abdul, Jasmine Guy, Jody Watley, Eric B & Rakim, Third Bass, Big Daddy Kane, EPMD, and Chaka Khan. According to Chuck D, "We had tight dealings with MCA Records and were talking about taking three guys that were left over from New Edition and coming up with an album for them. The three happened to be Ricky Bell, Michael Bivins, and Ronnie DeVoe, later to become Bell Biv DeVoe. Ralph Tresvant had been slated to do a solo album for years, Bobby Brown had left New Edition and experienced some solo success beginning in 1988, and Johnny Gill had just been recruited to come in, but [he] had | Strikes Black, continued this trend, with songs like "Can't Truss It", which addressed the history of slavery and how the black community can fight back against oppression; "I Don't Wanna be Called Yo Nigga", a track that takes issue with the use of the word nigga outside of its original derogatory context.

Legacy Public Enemy made contributions to the hip-hop world with sonic experimentation as well as political and cultural consciousness, which infused itself into skilled and poetic rhymes. Critic Stephen Thomas Erlewine wrote that "PE brought in elements of free jazz, hard funk, even musique concrète, via [its] producing team the Bomb Squad, creating a dense, ferocious sound unlike anything that came before." Public Enemy held a strong, pro-black, political stance. Before PE, politically motivated hip-hop was defined by a few tracks by Ice-T, Grandmaster Flash and the Furious Five, Kurtis Blow and Boogie Down Productions. Other politically motivated opinions were shared by prototypical artists Gil Scott-Heron and the Last Poets. PE was a revolutionary hip-hop act whose entire image rested on a specified political stance. With the successes of Public Enemy, many hip-hop artists began to celebrate Afrocentric themes, such as Kool Moe Dee, Gang Starr, X Clan, Eric B. & Rakim, Queen Latifah, the Jungle Brothers, and A Tribe Called Quest.

to drift from possibly as far as from their present locations to positions only from their current location. South America became linked to North America through the Isthmus of Panama, bringing a nearly complete end to South America's distinctive marsupial fauna. The formation of the isthmus had major consequences on global temperatures, because warm equatorial ocean currents were cut off, and the cold Arctic and Antarctic waters lowered temperatures in the now-isolated Atlantic Ocean. Most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas. Africa's collision with Asia created the Mediterranean, cutting off the remnants of the Tethys Ocean. During the Pleistocene, the modern continents were essentially at their present positions; the tectonic plates on which they sit have probably moved at most from each other since the beginning of the period. Climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. Ice sheets grew on Antarctica. The formation of an Arctic ice cap around 3 million years ago is signaled by an abrupt shift in oxygen isotope ratios and ice-rafted cobbles in the North Atlantic and North Pacific Ocean beds. Mid-latitude glaciation probably began before the end of the epoch. The global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas. The Pleistocene climate was characterized by repeated glacial cycles during which continental glaciers pushed to the 40th parallel in some places. Four major glacial events have been identified, as well as many minor intervening events. A major event is a general glacial excursion, termed a "glacial". Glacials are separated by "interglacials". During a glacial, the glacier experiences minor advances and retreats. The minor excursion is a "stadial"; times between stadials are "interstadials". Each glacial advance tied up huge volumes of water in continental ice sheets deep, resulting in temporary sea level drops of or more over the entire surface of the Earth. During interglacial times, such as at present, drowned coastlines were common, mitigated by isostatic or other emergent motion of some regions. The effects of glaciation were global. Antarctica was ice-bound throughout the Pleistocene and the preceding Pliocene. The Andes were covered in the south by the Patagonian ice cap. There were glaciers in New Zealand and Tasmania. The now decaying glaciers of Mount Kenya, Mount Kilimanjaro, and the Ruwenzori Range in east and central Africa were larger. Glaciers existed in the mountains of Ethiopia and to the west in the Atlas mountains. In the northern hemisphere, many glaciers fused into one. The Cordilleran Ice Sheet covered the North American northwest; the Laurentide covered the east. The Fenno-Scandian ice sheet covered northern Europe, including Great Britain; the Alpine ice sheet covered the Alps. Scattered domes stretched across Siberia and the Arctic shelf. The northern seas were frozen. During the late Upper Paleolithic (Latest Pleistocene) BP, the Beringia land bridge between Asia and North America was blocked by ice, which may have prevented early Paleo-Indians such as the Clovis culture from directly crossing Beringia to reach the Americas. According to Mark Lynas (through collected data), the Pleistocene's overall climate could be characterized as a continuous El Niño with trade winds in the south Pacific weakening or heading east, warm air rising near Peru, warm water spreading from the west Pacific and the Indian Ocean to the east Pacific, and other El Niño markers. The Paleolithic is often held to finish at the end of the ice age (the end of the Pleistocene epoch), and Earth's climate became warmer. This may have caused or contributed to the extinction of the Pleistocene megafauna, although it is also possible that the late Pleistocene extinctions were (at least in part) caused by other factors such as disease and overhunting by humans. New research suggests that the extinction of the woolly mammoth may have been caused by the combined effect of climatic change and human hunting. Scientists suggest that climate change during the end of the Pleistocene caused the mammoths' habitat to shrink in size, resulting in a drop in population. The small populations were then hunted out by Paleolithic humans. The global warming that occurred during the end of the Pleistocene and the beginning of the Holocene may have made it easier for humans to reach mammoth habitats that were previously frozen and inaccessible. Small populations of woolly mammoths survived on isolated Arctic islands, Saint Paul Island and Wrangel Island, until BP and BP respectively. The Wrangel Island population became extinct around the same time the island was settled by prehistoric humans. There is no evidence of prehistoric human presence on Saint Paul island (though early human settlements dating as far back as 6500 BP were found on the nearby Aleutian Islands). Human way of life Nearly all of our knowledge of Paleolithic human culture and way of life comes from archaeology and ethnographic comparisons to modern hunter-gatherer cultures such as the !Kung San who live similarly to their Paleolithic predecessors. The economy of a typical Paleolithic society was a hunter-gatherer economy. Humans hunted wild animals for meat and gathered food, firewood, and materials for their tools, clothes, or shelters. Human population density was very low, around only . This was most likely due to low body fat, infanticide, women regularly engaging in intense endurance exercise, late weaning of infants, and a nomadic lifestyle. Like contemporary hunter-gatherers, Paleolithic humans enjoyed an abundance of leisure time unparalleled in both Neolithic farming societies and modern industrial societies. At the end of the Paleolithic, specifically the Middle or Upper Paleolithic, humans began to produce works of art such as cave paintings, rock art and jewellery and began to engage in religious behavior such as burials and rituals. Distribution At the beginning of the Paleolithic, hominins were found primarily in eastern Africa, east of the Great Rift Valley. Most known hominin fossils dating earlier than one million years before present are found in this area, particularly in Kenya, Tanzania, and Ethiopia. By BP, groups of hominins began leaving Africa and settling southern Europe and Asia. Southern Caucasus was occupied by BP, and northern China was reached by BP. By the end of the Lower Paleolithic, members of the hominin family were living in what is now China, western Indonesia, and, in Europe, around the Mediterranean and as far north as England, France, southern Germany, and Bulgaria. Their further northward expansion may have been limited by the lack of control of fire: studies of cave settlements in Europe indicate no regular use of fire prior to BP. East Asian fossils from this period are typically placed in the genus Homo erectus. Very little fossil evidence is available at known Lower Paleolithic sites in Europe, but it is believed that hominins who inhabited these sites were likewise Homo erectus. There is no evidence of hominins in America, Australia, or almost anywhere in Oceania during this time period. Fates of these early colonists, and their relationships to modern humans, are still subject to debate. According to current archaeological and genetic models, there were at least two notable expansion events subsequent to peopling of Eurasia BP. Around 500,000 BP a group of early humans, frequently called Homo heidelbergensis, came to Europe from Africa and eventually evolved into Homo neanderthalensis (Neanderthals). In the Middle Paleolithic, Neanderthals were present in the region now occupied by Poland. Both Homo erectus and Homo neanderthalensis became extinct by the end of the Paleolithic. Descended from Homo sapiens, the anatomically modern Homo sapiens sapiens emerged in eastern Africa BP, left Africa around 50,000 BP, and expanded throughout the planet. Multiple hominid groups coexisted for some time in certain locations. Homo neanderthalensis were still found in parts of Eurasia BP years, and engaged in an unknown degree of interbreeding with Homo sapiens sapiens. DNA studies also suggest an unknown degree of interbreeding between Homo sapiens sapiens and Homo sapiens denisova. Hominin fossils not belonging either to Homo neanderthalensis or to Homo sapiens species, found in the Altai Mountains and Indonesia, were radiocarbon dated to BP and BP respectively. For the duration of the Paleolithic, human populations remained low, especially outside the equatorial region. The entire population of Europe between 16,000 and 11,000 BP likely averaged some 30,000 individuals, and between 40,000 and 16,000 BP, it was even lower at 4,000–6,000 individuals. However, remains of thousands of butchered animals and tools made by Palaeolithic humans were found in Lapa do Picareiro (pt), a cave in Portugal, dating back between 41,000 and 38,000 years ago. Technology Tools Paleolithic humans made tools of stone, bone (primarily deer), and wood. The early paleolithic hominins, Australopithecus, were the first users of stone tools. Excavations in Gona, Ethiopia have produced thousands of artifacts, and through radioisotopic dating and magnetostratigraphy, the sites can be firmly dated to 2.6 million years ago. Evidence shows these early hominins intentionally selected raw stone with good flaking qualities and chose appropriate sized stones for their needs to produce sharp-edged tools for cutting. The earliest Paleolithic stone tool industry, the Oldowan, began around 2.6 million years ago. It produced tools such as choppers, burins, and stitching awls. It was completely replaced around 250,000 years ago by the more complex Acheulean industry, which was first conceived by Homo ergaster around 1.8–1.65 million years ago. The Acheulean implements completely vanish from the archaeological record around 100,000 years ago and were replaced by more complex Middle Paleolithic tool kits such as the Mousterian and the Aterian industries. Lower Paleolithic humans used a variety of stone tools, including hand axes and choppers. Although they appear to have used hand axes often, there is disagreement about their use. Interpretations range from cutting and chopping tools, to digging implements, to flaking cores, to the use in traps, and as a purely ritual significance, perhaps in courting behavior. William H. Calvin has suggested that some hand axes could have served as "killer Frisbees" meant to be thrown at a herd of animals at a waterhole so as to stun one of them. There are no indications of hafting, and some artifacts are far too large for that. Thus, a thrown hand axe would not usually have penetrated deeply enough to cause very serious injuries. Nevertheless, it could have been an effective weapon for defense against predators. Choppers and scrapers were likely used for skinning and butchering scavenged animals and sharp-ended sticks were often obtained for digging up edible roots. Presumably, early humans used wooden spears as early as 5 million years ago to hunt small animals, much as their relatives, chimpanzees, have been observed to do in Senegal, Africa. Lower Paleolithic humans constructed shelters, such as the possible wood hut at Terra Amata. Fire use Fire was used by the Lower Paleolithic hominins Homo erectus and Homo ergaster as early as 300,000 to 1.5 million years ago and possibly even earlier by the early Lower Paleolithic (Oldowan) hominin Homo habilis or by robust Australopithecines such as Paranthropus. However, the use of fire only became common in the societies of the following Middle Stone Age and Middle Paleolithic. Use of fire reduced mortality rates and provided protection against predators. Early hominins may have begun to cook their food as early as the Lower Paleolithic ( million years ago) or at the latest in the early Middle Paleolithic ( years ago). Some scientists have hypothesized that hominins began cooking food to defrost frozen meat, which would help ensure their survival in cold regions. Archaeologists cite morphological shifts in cranial anatomy as evidence for emergence of cooking and food processing technologies. These morphological changes include decreases in molar and jaw size, thinner tooth enamel, and decrease in gut volume During much of the Pleistocene epoch, our ancestors relied on simple food processing techniques such as roasting The Upper Palaeolithic saw the emergence of boiling, an advance in food processing technology which rendered plant foods more digestible, decreased their toxicity, and maximised their nutritional value Thermally altered rock (heated stones) are easily identifiable in the archaeological record. Stone-boiling and pit-baking were common techniques which involved heating large pebbles then transferring the hot stones into a perishable container to heat the water This technology is typified in the Middle Palaeolithic example of the Abri Pataud hearths Raft The Lower Paleolithic Homo erectus possibly invented rafts ( BP) to travel over large bodies of water, which may have allowed a group of Homo erectus to reach the island of Flores and evolve into the small hominin Homo floresiensis. However, this hypothesis is disputed within the anthropological community. The possible use of rafts during the Lower Paleolithic may indicate that Lower Paleolithic hominins such as Homo erectus were more advanced than previously believed, and may have even spoken an early form of modern language. Supplementary evidence from Neanderthal and modern human sites located around the Mediterranean Sea, such as Coa de sa Multa ( BP), has also indicated that both Middle and Upper Paleolithic humans used rafts to travel over large bodies of water (i.e. the Mediterranean Sea) for the purpose of colonizing other bodies of land. Advanced tools By around 200,000 BP, Middle Paleolithic stone tool manufacturing spawned a tool making technique known as the prepared-core technique, that was more elaborate than previous Acheulean techniques. This technique increased efficiency by allowing the creation of more controlled and consistent flakes. It allowed Middle Paleolithic humans to create stone tipped spears, which were the earliest composite tools, by hafting sharp, pointy stone flakes onto wooden shafts. In addition to improving tool making methods, the Middle Paleolithic also saw an improvement of the tools themselves that allowed access to a wider variety and amount of food sources. For example, microliths or small stone tools or points were invented around 70,000–65,000 BP and were essential to the invention of bows and spear throwers in the following Upper Paleolithic. Harpoons were invented and used for the first time during the late Middle Paleolithic ( BP); the invention of these devices brought fish into the human diets, which provided a hedge against starvation and a more abundant food supply. Thanks to their technology and their advanced social structures, Paleolithic groups such as the Neanderthals—who had a Middle Paleolithic level of technology—appear to have hunted large game just as well as Upper Paleolithic modern humans. and the Neanderthals in particular may have likewise hunted with projectile weapons. Nonetheless, Neanderthal use of projectile weapons in hunting occurred very rarely (or perhaps never) and the Neanderthals hunted large game animals mostly by ambushing them and attacking them with mêlée weapons such as thrusting spears rather than attacking them from a distance with projectile weapons. Other inventions During the Upper Paleolithic, further inventions were made, such as the net ( or BP) bolas, the spear thrower ( BP), the bow and arrow ( or BP) and the oldest example of ceramic art, the Venus of Dolní Věstonice ( BP). Kilu Cave at Buku island, Solomon Islands, demonstrates navigation of some 60 km of open ocean at 30,000 BCcal. Early dogs were domesticated sometime between 30,000 and 14,000 BP, presumably to aid in hunting. However, the earliest instances of successful domestication of dogs may be much more ancient than this. Evidence from canine DNA collected by Robert K. Wayne suggests that dogs may have been first domesticated in the late Middle Paleolithic around 100,000 BP or perhaps even earlier. Archaeological evidence from the Dordogne region of France demonstrates that members of the European early Upper Paleolithic culture known as the Aurignacian used calendars ( BP). This was a lunar calendar that was used to document the phases of the moon. Genuine solar calendars did not appear until the Neolithic. Upper Paleolithic cultures were probably able to time the migration of game animals such as wild horses and deer. This ability allowed humans to become efficient hunters and to exploit a wide variety of game animals. Recent research indicates that the Neanderthals | variety of lower-quality art and figurines, and he identifies a wide range of skill and ages among the artists. He also points out that the main themes in the paintings and other artifacts (powerful beasts, risky hunting scenes and the over-sexual representation of women) are to be expected in the fantasies of adolescent males during the Upper Paleolithic. The "Venus" figurines have been theorized, not universally, as representing a mother goddess; the abundance of such female imagery has inspired the theory that religion and society in Paleolithic (and later Neolithic) cultures were primarily interested in, and may have been directed by, women. Adherents of the theory include archaeologist Marija Gimbutas and feminist scholar Merlin Stone, the author of the 1976 book When God Was a Woman. Other explanations for the purpose of the figurines have been proposed, such as Catherine McCoid and LeRoy McDermott's hypothesis that they were self-portraits of woman artists and R.Dale Gutrie's hypothesis that served as "stone age pornography". Music The origins of music during the Paleolithic are unknown. The earliest forms of music probably did not use musical instruments other than the human voice or natural objects such as rocks. This early music would not have left an archaeological footprint. Music may have developed from rhythmic sounds produced by daily chores, for example, cracking open nuts with stones. Maintaining a rhythm while working may have helped people to become more efficient at daily activities. An alternative theory originally proposed by Charles Darwin explains that music may have begun as a hominin mating strategy. Bird and other animal species produce music such as calls to attract mates. This hypothesis is generally less accepted than the previous hypothesis, but nonetheless provides a possible alternative. Upper Paleolithic (and possibly Middle Paleolithic) humans used flute-like bone pipes as musical instruments, and music may have played a large role in the religious lives of Upper Paleolithic hunter-gatherers. As with modern hunter-gatherer societies, music may have been used in ritual or to help induce trances. In particular, it appears that animal skin drums may have been used in religious events by Upper Paleolithic shamans, as shown by the remains of drum-like instruments from some Upper Paleolithic graves of shamans and the ethnographic record of contemporary hunter-gatherer shamanic and ritual practices. Religion and beliefs According to James B. Harrod humankind first developed religious and spiritual beliefs during the Middle Paleolithic or Upper Paleolithic. Controversial scholars of prehistoric religion and anthropology, James Harrod and Vincent W. Fallio, have recently proposed that religion and spirituality (and art) may have first arisen in Pre-Paleolithic chimpanzees or Early Lower Paleolithic (Oldowan) societies. According to Fallio, the common ancestor of chimpanzees and humans experienced altered states of consciousness and partook in ritual, and ritual was used in their societies to strengthen social bonding and group cohesion. Middle Paleolithic humans' use of burials at sites such as Krapina, Croatia ( BP) and Qafzeh, Israel ( BP) have led some anthropologists and archaeologists, such as Philip Lieberman, to believe that Middle Paleolithic humans may have possessed a belief in an afterlife and a "concern for the dead that transcends daily life". Cut marks on Neanderthal bones from various sites, such as Combe-Grenal and Abri Moula in France, suggest that the Neanderthals—like some contemporary human cultures—may have practiced ritual defleshing for (presumably) religious reasons. According to recent archaeological findings from Homo heidelbergensis sites in Atapuerca, humans may have begun burying their dead much earlier, during the late Lower Paleolithic; but this theory is widely questioned in the scientific community. Likewise, some scientists have proposed that Middle Paleolithic societies such as Neanderthal societies may also have practiced the earliest form of totemism or animal worship, in addition to their (presumably religious) burial of the dead. In particular, Emil Bächler suggested (based on archaeological evidence from Middle Paleolithic caves) that a bear cult was widespread among Middle Paleolithic Neanderthals. A claim that evidence was found for Middle Paleolithic animal worship BCE originates from the Tsodilo Hills in the African Kalahari desert has been denied by the original investigators of the site. Animal cults in the Upper Paleolithic, such as the bear cult, may have had their origins in these hypothetical Middle Paleolithic animal cults. Animal worship during the Upper Paleolithic was intertwined with hunting rites. For instance, archaeological evidence from art and bear remains reveals that the bear cult apparently involved a type of sacrificial bear ceremonialism, in which a bear was shot with arrows, finished off by a shot or thrust in the lungs, and ritually worshipped near a clay bear statue covered by a bear fur with the skull and the body of the bear buried separately. Barbara Ehrenreich controversially theorizes that the sacrificial hunting rites of the Upper Paleolithic (and by extension Paleolithic cooperative big-game hunting) gave rise to war or warlike raiding during the following Epipaleolithic and Mesolithic or late Upper Paleolithic. The existence of anthropomorphic images and half-human, half-animal images in the Upper Paleolithic may further indicate that Upper Paleolithic humans were the first people to believe in a pantheon of gods or supernatural beings, though such images may instead indicate shamanistic practices similar to those of contemporary tribal societies. The earliest known undisputed burial of a shaman (and by extension the earliest undisputed evidence of shamans and shamanic practices) dates back to the early Upper Paleolithic era ( BP) in what is now the Czech Republic. However, during the early Upper Paleolithic it was probably more common for all members of the band to participate equally and fully in religious ceremonies, in contrast to the religious traditions of later periods when religious authorities and part-time ritual specialists such as shamans, priests and medicine men were relatively common and integral to religious life. Religion was possibly apotropaic; specifically, it may have involved sympathetic magic. The Venus figurines, which are abundant in the Upper Paleolithic archaeological record, provide an example of possible Paleolithic sympathetic magic, as they may have been used for ensuring success in hunting and to bring about fertility of the land and women. The Upper Paleolithic Venus figurines have sometimes been explained as depictions of an earth goddess similar to Gaia, or as representations of a goddess who is the ruler or mother of the animals. James Harrod has described them as representative of female (and male) shamanistic spiritual transformation processes. Diet and nutrition Paleolithic hunting and gathering people ate varying proportions of vegetables (including tubers and roots), fruit, seeds (including nuts and wild grass seeds) and insects, meat, fish, and shellfish. However, there is little direct evidence of the relative proportions of plant and animal foods. Although the term "paleolithic diet", without references to a specific timeframe or locale, is sometimes used with an implication that most humans shared a certain diet during the entire era, that is not entirely accurate. The Paleolithic was an extended period of time, during which multiple technological advances were made, many of which had impact on human dietary structure. For example, humans probably did not possess the control of fire until the Middle Paleolithic, or tools necessary to engage in extensive fishing. On the other hand, both these technologies are generally agreed to have been widely available to humans by the end of the Paleolithic (consequently, allowing humans in some regions of the planet to rely heavily on fishing and hunting). In addition, the Paleolithic involved a substantial geographical expansion of human populations. During the Lower Paleolithic, ancestors of modern humans are thought to have been constrained to Africa east of the Great Rift Valley. During the Middle and Upper Paleolithic, humans greatly expanded their area of settlement, reaching ecosystems as diverse as New Guinea and Alaska, and adapting their diets to whatever local resources were available. Another view is that until the Upper Paleolithic, humans were frugivores (fruit eaters) who supplemented their meals with carrion, eggs, and small prey such as baby birds and mussels, and only on rare occasions managed to kill and consume big game such as antelopes. This view is supported by studies of higher apes, particularly chimpanzees. Chimpanzees are the closest to humans genetically, sharing more than 96% of their DNA code with humans, and their digestive tract is functionally very similar to that of humans. Chimpanzees are primarily frugivores, but they could and would consume and digest animal flesh, given the opportunity. In general, their actual diet in the wild is about 95% plant-based, with the remaining 5% filled with insects, eggs, and baby animals. In some ecosystems, however, chimpanzees are predatory, forming parties to hunt monkeys. Some comparative studies of human and higher primate digestive tracts do suggest that humans have evolved to obtain greater amounts of calories from sources such as animal foods, allowing them to shrink the size of the gastrointestinal tract relative to body mass and to increase the brain mass instead. Anthropologists have diverse opinions about the proportions of plant and animal foods consumed. Just as with still existing hunters and gatherers, there were many varied "diets" in different groups, and also varying through this vast amount of time. Some paleolithic hunter-gatherers consumed a significant amount of meat and possibly obtained most of their food from hunting, while others were believed to have a primarily plant-based diet. Most, if not all, are believed to have been opportunistic omnivores. One hypothesis is that carbohydrate tubers (plant underground storage organs) may have been eaten in high amounts by pre-agricultural humans. It is thought that the Paleolithic diet included as much as per day of fruit and vegetables. The relative proportions of plant and animal foods in the diets of Paleolithic people often varied between regions, with more meat being necessary in colder regions (which weren't populated by anatomically modern humans until BP). It is generally agreed that many modern hunting and fishing tools, such as fish hooks, nets, bows, and poisons, weren't introduced until the Upper Paleolithic and possibly even Neolithic. The only hunting tools widely available to humans during any significant part of the Paleolithic were hand-held spears and harpoons. There's evidence of Paleolithic people killing and eating seals and elands as far as BP. On the other hand, buffalo bones found in African caves from the same period are typically of very young or very old individuals, and there's no evidence that pigs, elephants, or rhinos were hunted by humans at the time. Paleolithic peoples suffered less famine and malnutrition than the Neolithic farming tribes that followed them. This was partly because Paleolithic hunter-gatherers accessed a wider variety of natural foods, which allowed them a more nutritious diet and a decreased risk of famine. Many of the famines experienced by Neolithic (and some modern) farmers were caused or amplified by their dependence on a small number of crops. It is thought that wild foods can have a significantly different nutritional profile than cultivated foods. The greater amount of meat obtained by hunting big game animals in Paleolithic diets than Neolithic diets may have also allowed Paleolithic hunter-gatherers to enjoy a more nutritious diet than Neolithic agriculturalists. It has been argued that the shift from hunting and gathering to agriculture resulted in an increasing focus on a limited variety of foods, with meat likely taking a back seat to plants. It is also unlikely that Paleolithic hunter-gatherers were affected by modern diseases of affluence such as type 2 diabetes, coronary heart disease, and cerebrovascular disease, because they ate mostly lean meats and plants and frequently engaged in intense physical activity, and because the average lifespan was shorter than the age of common onset of these conditions. Large-seeded legumes were part of the human diet long before the Neolithic Revolution, as evident from archaeobotanical finds from the Mousterian layers of Kebara Cave, in Israel. There is evidence suggesting that Paleolithic societies were gathering wild cereals for food use at least as early as 30,000 years ago. However, seeds—such as grains and beans—were rarely eaten and never in large quantities on a daily basis. Recent archaeological evidence also indicates that winemaking may have originated in the Paleolithic, when early humans drank the juice of naturally fermented wild grapes from animal-skin pouches. Paleolithic humans consumed animal organ meats, including the livers, kidneys, and brains. Upper Paleolithic cultures appear to have had significant knowledge about plants and herbs and may have, albeit very rarely, practiced rudimentary forms of horticulture. In particular, bananas and tubers may have been cultivated as early as 25,000 BP in southeast Asia. Late Upper Paleolithic societies also appear to have occasionally practiced pastoralism and animal husbandry, presumably for dietary reasons. For instance, some European late Upper Paleolithic cultures domesticated and raised reindeer, presumably for their meat or milk, as early as 14,000 BP. Humans also probably consumed hallucinogenic plants during the Paleolithic. The Aboriginal Australians have been consuming a variety of native animal and plant foods, called bushfood, for an estimated 60,000 years, since the Middle Paleolithic. In February 2019, scientists reported evidence, based on isotope studies, that at least some Neanderthals may have eaten meat. People during the Middle Paleolithic, such as the Neanderthals and Middle Paleolithic Homo sapiens in Africa, began to catch shellfish for food as revealed by shellfish cooking in Neanderthal sites in Italy about 110,000 years ago and in Middle Paleolithic Homo sapiens sites at Pinnacle Point, South Africa around 164,000 BP. Although fishing only became common during the Upper Paleolithic, fish have been part of human diets long before the dawn of the Upper Paleolithic and have certainly been consumed by humans since at least the Middle Paleolithic. For example, the Middle Paleolithic Homo sapiens in the region now occupied by the Democratic Republic of the Congo hunted large -long catfish with specialized barbed fishing points as early as 90,000 years ago. The invention of fishing allowed some Upper Paleolithic and later hunter-gatherer societies to become sedentary or semi-nomadic, which altered their social structures. Example societies are the Lepenski Vir as well as some contemporary hunter-gatherers, such as the Tlingit. In some instances (at least the Tlingit), they developed social stratification, slavery, and complex social structures such as chiefdoms. Anthropologists such as Tim White suggest that cannibalism was common in human societies prior to the beginning of the Upper Paleolithic, based on the large amount of “butchered human" bones found |

When the medal with Distinction is awarded, the star may be presented descending from a neck ribbon and can be identified by its larger size than the standard medal (illustrated). Both medals may also be worn in miniature form on a ribbon on the left chest, with a silver North American bald eagle with spread wings on the ribbon, |
of sticky collision) dust particles in the disk steadily accumulate mass to form ever-larger bodies. Local concentrations of mass known as planetesimals form, and these accelerate the accretion process by drawing in additional material by their gravitational attraction. These concentrations become ever denser until they collapse inward under gravity to form protoplanets. After a planet reaches a mass somewhat larger than Mars' mass, it begins to accumulate an extended atmosphere, greatly increasing the capture rate of the planetesimals by means of atmospheric drag. Depending on the accretion history of solids and gas, a giant planet, an ice giant, or a terrestrial planet may result. It is thought that the regular satellites of Jupiter, Saturn, and Uranus formed in a similar way; however, Triton was likely captured by Neptune, and Earth's Moon and Pluto's Charon might have formed in collisions. When the protostar has grown such that it ignites to form a star, the surviving disk is removed from the inside outward by photoevaporation, the solar wind, Poynting–Robertson drag and other effects. Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a single larger planet or release material for other larger protoplanets or planets to absorb. Those objects that have become massive enough will capture most matter in their orbital neighbourhoods to become planets. Protoplanets that have avoided collisions may become natural satellites of planets through a process of gravitational capture, or remain in belts of other objects to become either dwarf planets or small bodies. The energetic impacts of the smaller planetesimals (as well as radioactive decay) will heat up the growing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by mass, developing a denser core. Smaller terrestrial planets lose most of their atmospheres because of this accretion, but the lost gases can be replaced by outgassing from the mantle and from the subsequent impact of comets. (Smaller planets will lose any atmosphere they gain through various escape mechanisms.) With the discovery and observation of planetary systems around stars other than the Sun, it is becoming possible to elaborate, revise or even replace this account. The level of metallicity—an astronomical term describing the abundance of chemical elements with an atomic number greater than 2 (helium)—is now thought to determine the likelihood that a star will have planets. Hence, it is thought that a metal-rich population I star will likely have a more substantial planetary system than a metal-poor, population II star. Solar System According to the IAU definition, there are eight planets in the Solar System, which are in increasing distance from the Sun: ☿ Mercury ♀ Venus 🜨 Earth ♂ Mars ♃ Jupiter ♄ Saturn ⛢ Uranus ♆ Neptune Jupiter is the largest, at 318 Earth masses, whereas Mercury is the smallest, at 0.055 Earth masses. The planets of the Solar System can be divided into categories based on their composition: Terrestrials: Planets that are similar to Earth, with bodies largely composed of rock and metal: Mercury, Venus, Earth, and Mars. At 0.055 Earth masses, Mercury is the smallest terrestrial planet (and smallest planet) in the Solar System. Earth is the largest terrestrial planet. Giant planets (Jovians): Massive planets significantly more massive than the terrestrials: Jupiter, Saturn, Uranus, and Neptune. Gas giants: Jupiter and Saturn, are giant planets primarily composed of hydrogen and helium and are the most massive planets in the Solar System. Jupiter, at 318 Earth masses, is the largest planet in the Solar System. Saturn is one third as massive, at 95 Earth masses. Ice giants: Uranus and Neptune, are primarily composed of low-boiling-point materials such as water, methane, and ammonia, with thick atmospheres of hydrogen and helium. They have a significantly lower mass than the gas giants (only 14 and 17 Earth masses). The number of geophysical planets in the Solar System is unknown - previously considered to be potentially in the hundreds, but now only estimated at only the low double digits. These include the eight classical planets, as well as two more populations. Nine objects are generally agreed to be dwarf planets, with some others being disputed candidates. Dwarf planets are gravitationally rounded, but do not clear their orbits. In increasing order of average distance from the Sun, they are: Ceres is the largest object in the asteroid belt, between the orbits of Mars and Jupiter. The other eight all orbit beyond Neptune. Orcus, Pluto, Haumea, Quaoar, and Makemake orbit in the Kuiper belt, which is a second asteroid belt beyond the orbit of Neptune. Gonggong and Eris orbit in the scattered disc, which is somewhat further out and, unlike the Kuiper belt, is unstable towards interactions with Neptune. Sedna is the largest known detached object, a population that never comes close enough to the Sun to interact with any of the classical planets: the origins of their orbits are still being debated. All nine of these would be considered icy planets: they are similar to terrestrial planets in having a solid surface, but they are made of ice and rock, rather than rock and metal. All of them are smaller than Mercury, with Pluto being the largest known dwarf planet, and Eris being the most massive known. There are also at least nineteen planetary-mass moons or satellite planets, i.e. moons large enough to take on ellipsoidal shapes. The nineteen generally agreed are: One satellite of Earth – the Moon Four satellites of Jupiter – Io, Europa, Ganymede, and Callisto Seven satellites of Saturn – Mimas, Enceladus, Tethys, Dione, Rhea, Titan, and Iapetus Five satellites of Uranus – Miranda, Ariel, Umbriel, Titania, and Oberon One satellite of Neptune – Triton One satellite of Pluto – Charon The Moon, Io, and Europa have compositions similar to the terrestrial planets; the others are made of ice and rock like the dwarf planets, with Tethys being made of almost pure ice. (Europa is often considered an icy planet, though, because its surface ice layer makes it difficult to study its interior.) Ganymede and Titan are larger than Mercury by radius, and Callisto almost equals it, but all three are much less massive. Mimas is the smallest object generally agreed to be a geophysical planet, at about six millionths of Earth's mass, though there are many larger bodies that may not be geophysical planets. Planetary attributes Exoplanets An exoplanet (extrasolar planet) is a planet outside the Solar System. In early 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. This discovery was confirmed, and is generally considered to be the first definitive detection of exoplanets. These pulsar planets are believed to have formed from the unusual remnants of the supernova that produced the pulsar, in a second round of planet formation, or else to be the remaining rocky cores of giant planets that survived the supernova and then decayed into their current orbits. The first confirmed discovery of an extrasolar planet orbiting an ordinary main-sequence star occurred on 6 October 1995, when Michel Mayor and Didier Queloz of the University of Geneva announced the detection of an exoplanet around 51 Pegasi. From then until the Kepler mission most known extrasolar planets were gas giants comparable in mass to Jupiter or larger as they were more easily detected. The catalog of Kepler candidate planets consists mostly of planets the size of Neptune and smaller, down to smaller than Mercury. There are types of planets that do not exist in the Solar System: super-Earths and mini-Neptunes, which could be rocky like Earth or a mixture of volatiles and gas like Neptune—the dividing line between the two is currently thought to occur at about twice the mass of Earth. There are hot Jupiters that orbit very close to their star and may evaporate to become chthonian planets, which are the leftover cores. Another possible type of planet is carbon planets, which form in systems with a higher proportion of carbon than in the Solar System. A 2012 study, analyzing gravitational microlensing data, estimates an average of at least 1.6 bound planets for every star in the Milky Way. On 20 December 2011, the Kepler Space Telescope team reported the discovery of the first Earth-size exoplanets, Kepler-20e and Kepler-20f, orbiting a Sun-like star, Kepler-20. Around 1 in 5 Sun-like stars have an "Earth-sized" planet in the habitable zone, so the nearest would be expected to be within 12 light-years distance from Earth. The frequency of occurrence of such terrestrial planets is one of the variables in the Drake equation, which estimates the number of intelligent, communicating civilizations that exist in the Milky Way. There are exoplanets that are much closer to their parent star than any planet in the Solar System is to the Sun, and there are also exoplanets that are much farther from their star. Mercury, the closest planet to the Sun at 0.4 AU, takes 88 days for an orbit, but the shortest known orbits for exoplanets take only a few hours, see Ultra-short period planet. The Kepler-11 system has five of its planets in shorter orbits than Mercury's, all of them much more massive than Mercury. Neptune is 30 AU from the Sun and takes 165 years to orbit, but there are exoplanets that are hundreds of AU from their star and take more than a thousand years to orbit, e.g. 1RXS1609 b. Attributes Although each planet has unique physical characteristics, a number of broad commonalities do exist among them. Some of these characteristics, such as rings or natural satellites, have only as yet been observed in planets in the Solar System, whereas others are also commonly observed in extrasolar planets. Dynamic characteristics Orbit In the Solar System, all the planets orbit the Sun in the same direction as the Sun rotates (counter-clockwise as seen from above the Sun's north pole). At least one extrasolar planet, WASP-17b, has been found to orbit in the opposite direction to its star's rotation. The period of one revolution of a planet's orbit is known as its sidereal period or year. A planet's year depends on its distance from its star; the farther a planet is from its star, not only the longer the distance it must travel, but also the slower its speed, because it is less affected by its star's gravity. No planet's orbit is perfectly circular, and hence the distance of each varies over the course of its year. The closest approach to its star is called its periastron (perihelion in the Solar System), whereas its farthest separation from the star is called its apastron (aphelion). As a planet approaches periastron, its speed increases as it trades gravitational potential energy for kinetic energy, just as a falling object on Earth accelerates as it falls; as the planet reaches apastron, its speed decreases, just as an object thrown upwards on Earth slows down as it reaches the apex of its trajectory. Each planet's orbit is delineated by a set of elements: The eccentricity of an orbit describes how elongated a planet's orbit is. Planets with low eccentricities have more circular orbits, whereas planets with high eccentricities have more elliptical orbits. The planets in the Solar System have very low eccentricities, and thus nearly circular orbits. Comets and Kuiper belt objects (as well as several extrasolar planets) have very high eccentricities, and thus exceedingly elliptical orbits. The semi-major axis is the distance from a planet to the half-way point along the longest diameter of its elliptical orbit (see image). This distance is not the same as its apastron, because no planet's orbit has its star at its exact centre. The inclination of a planet tells how far above or below an established reference plane its orbit lies. In the Solar System, the reference plane is the plane of Earth's orbit, called the ecliptic. For extrasolar planets, the plane, known as the sky plane or plane of the sky, is the plane perpendicular to the observer's line of sight from Earth. The eight planets of the Solar System all lie very close to the ecliptic; comets and Kuiper belt objects like Pluto are at far more extreme angles to it. The points at which a planet crosses above and below its reference plane are called its ascending and descending nodes. The longitude of the ascending node is the angle between the reference plane's 0 longitude and the planet's ascending node. The argument of periapsis (or perihelion in the Solar System) is the angle between a planet's ascending node and its closest approach to its star. Axial tilt Planets also have varying degrees of axial tilt; they lie at an angle to the plane of their stars' equators. This causes the amount of light received by each hemisphere to vary over the course of its year; when the northern hemisphere points away from its star, the southern hemisphere points towards it, and vice versa. Each planet therefore has seasons, changes to the climate over the course of its year. The time at which each hemisphere points farthest or nearest from its star is known as its solstice. Each planet has two in the course of its orbit; when one hemisphere has its summer solstice, when its day is longest, the other has its winter solstice, when its day is shortest. The varying amount of light and heat received by each hemisphere creates annual changes in weather patterns for each half of the planet. Jupiter's axial tilt is very small, so its seasonal variation is minimal; Uranus, on the other hand, has an axial tilt so extreme it is virtually on its side, which means that its hemispheres are either perpetually in sunlight or perpetually in darkness around the time of its solstices. Among extrasolar planets, axial tilts are not known for certain, though most hot Jupiters are believed to have negligible to no axial tilt as a result of their proximity to their stars. Rotation The planets rotate around invisible axes through their centres. A planet's rotation period is known as a stellar day. Most of the planets in the Solar System rotate in the same direction as they orbit the Sun, which is counter-clockwise as seen from above the Sun's north pole, the exceptions being Venus and Uranus, which rotate clockwise, though Uranus's extreme axial tilt means there are differing conventions on which of its poles is "north", and therefore whether it is rotating clockwise or anti-clockwise. Regardless of which convention is used, Uranus has a retrograde rotation relative to its orbit. The rotation of a planet can be induced by several factors during formation. A net angular momentum can be induced by the individual angular momentum contributions of accreted objects. The accretion of gas by the giant planets can also contribute to the angular momentum. Finally, during the last stages of planet building, a stochastic process of protoplanetary accretion can randomly alter the spin axis of the planet. There is great variation in the length of day between the planets, with Venus taking 243 days to rotate, and the giant planets only a few hours. The rotational periods of extrasolar planets are not known. However, for "hot" Jupiters, their proximity | too many concordances between Greek and Babylonian naming conventions for them to have arisen separately. The translation was not perfect. For instance, the Babylonian Nergal was a god of war, and thus the Greeks identified him with Ares. Unlike Ares, Nergal was also god of pestilence and the underworld. Today, most people in the western world know the planets by names derived from the Olympian pantheon of gods. Although modern Greeks still use their ancient names for the planets, other European languages, because of the influence of the Roman Empire and, later, the Catholic Church, use the Roman (Latin) names rather than the Greek ones. The Romans, who, like the Greeks, were Indo-Europeans, shared with them a common pantheon under different names but lacked the rich narrative traditions that Greek poetic culture had given their gods. During the later period of the Roman Republic, Roman writers borrowed much of the Greek narratives and applied them to their own pantheon, to the point where they became virtually indistinguishable. When the Romans studied Greek astronomy, they gave the planets their own gods' names: Mercurius (for Hermes), Venus (Aphrodite), Mars (Ares), Iuppiter (Zeus) and Saturnus (Cronus). When subsequent planets were discovered in the 18th and 19th centuries, the naming practice was retained with Neptūnus (Poseidon). Uranus is unique in that it is named for a Greek deity rather than his Roman counterpart. Ceres, Orcus, Pluto, and Eris continued the Roman and Greek scheme; however, the other consensus dwarf planets are named after gods and goddesses from other cultures (e.g. Quaoar is named after a Tongva god). Objects beyond Neptune follow various naming conventions depending on their orbits: those in the 2:3 resonance with Neptune (the plutinos) are given names from underworld myths, while others are given names from creation myths. The moons (including the planetary-mass ones) are generally given names with some association with their parent planet. The planetary-mass moons of Jupiter are named after four of Zeus' lovers (or other sexual partners); those of Saturn are named after Cronus' brothers and sisters, the Titans; those of Uranus are named after characters from Shakespeare and Pope (originally specifically from fairy mythology, befitting Uranus as god of the sky and air, but that ended with the naming of Miranda). Neptune's planetary-mass moon Triton is named after the god's son; Pluto's planetary-mass moon Charon is named after the ferryman of the dead, who carries the souls of the newly deceased to the underworld (Pluto's domain). Some Romans, following a belief possibly originating in Mesopotamia but developed in Hellenistic Egypt, believed that the seven gods after whom the planets were named took hourly shifts in looking after affairs on Earth. The order of shifts went Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon (from the farthest to the closest planet). Therefore, the first day was started by Saturn (1st hour), second day by Sun (25th hour), followed by Moon (49th hour), Mars, Mercury, Jupiter and Venus. Because each day was named by the god that started it, this is also the order of the days of the week in the Roman calendar after the Nundinal cycle was rejected – and still preserved in many modern languages. In English, Saturday, Sunday, and Monday are straightforward translations of these Roman names. The other days were renamed after Tīw (Tuesday), Wōden (Wednesday), Þunor (Thursday), and Frīġ (Friday), the Anglo-Saxon gods considered similar or equivalent to Mars, Mercury, Jupiter, and Venus, respectively. Earth is the only planet whose name in English is not derived from Greco-Roman mythology. Because it was only generally accepted as a planet in the 17th century, there is no tradition of naming it after a god. (The same is true, in English at least, of the Sun and the Moon, though they are no longer generally considered planets.) The name originates from the Old English word eorþe, which was the word for "ground" and "dirt" as well as the Earth itself. As with its equivalents in the other Germanic languages, it derives ultimately from the Proto-Germanic word erþō, as can be seen in the English earth, the German Erde, the Dutch aarde, and the Scandinavian jord. Many of the Romance languages retain the old Roman word terra (or some variation of it) that was used with the meaning of "dry land" as opposed to "sea". The non-Romance languages use their own native words. The Greeks retain their original name, Γή (Ge). Non-European cultures use other planetary-naming systems. India uses a system based on the Navagraha, which incorporates the seven traditional planets (Surya for the Sun, Chandra for the Moon, Budha for Mercury, Shukra for Venus, Mangala for Mars, for Jupiter, and Shani for Saturn) and the ascending and descending lunar nodes Rahu and Ketu. China and the countries of eastern Asia historically subject to Chinese cultural influence (such as Japan, Korea and Vietnam) use a naming system based on the five Chinese elements: water (Mercury), metal (Venus), fire (Mars), wood (Jupiter) and earth (Saturn). In traditional Hebrew astronomy, the seven traditional planets have (for the most part) descriptive names – the Sun is חמה Ḥammah or "the hot one," the Moon is לבנה Levanah or "the white one," Venus is כוכב נוגה Kokhav Nogah or "the bright planet," Mercury is כוכב Kokhav or "the planet" (given its lack of distinguishing features), Mars is מאדים Ma'adim or "the red one," and Saturn is שבתאי Shabbatai or "the resting one" (in reference to its slow movement compared to the other visible planets). The odd one out is Jupiter, called צדק Tzedeq or "justice". Steiglitz suggests that this may be a euphemism for the original name of כוכב בעל Kokhav Ba'al or "Baal's planet", seen as idolatrous and euphemized in a similar manner to Ishbosheth from II Samuel. In Arabic, Mercury is عُطَارِد (ʿUṭārid, cognate with Ishtar / Astarte), Venus is الزهرة (az-Zuhara, "the bright one", an epithet of the goddess Al-'Uzzá), Earth is الأرض (al-ʾArḍ, from the same root as eretz), Mars is اَلْمِرِّيخ (al-Mirrīkh, meaning "featherless arrow" due to its retrograde motion), Jupiter is المشتري (al-Muštarī, "the reliable one", from Akkadian) and Saturn is زُحَل (Zuḥal, "withdrawer"). Formation It is not known with certainty how planets are formed. The prevailing theory is that they are formed during the collapse of a nebula into a thin disk of gas and dust. A protostar forms at the core, surrounded by a rotating protoplanetary disk. Through accretion (a process of sticky collision) dust particles in the disk steadily accumulate mass to form ever-larger bodies. Local concentrations of mass known as planetesimals form, and these accelerate the accretion process by drawing in additional material by their gravitational attraction. These concentrations become ever denser until they collapse inward under gravity to form protoplanets. After a planet reaches a mass somewhat larger than Mars' mass, it begins to accumulate an extended atmosphere, greatly increasing the capture rate of the planetesimals by means of atmospheric drag. Depending on the accretion history of solids and gas, a giant planet, an ice giant, or a terrestrial planet may result. It is thought that the regular satellites of Jupiter, Saturn, and Uranus formed in a similar way; however, Triton was likely captured by Neptune, and Earth's Moon and Pluto's Charon might have formed in collisions. When the protostar has grown such that it ignites to form a star, the surviving disk is removed from the inside outward by photoevaporation, the solar wind, Poynting–Robertson drag and other effects. Thereafter there still may be many protoplanets orbiting the star or each other, but over time many will collide, either to form a single larger planet or release material for other larger protoplanets or planets to absorb. Those objects that have become massive enough will capture most matter in their orbital neighbourhoods to become planets. Protoplanets that have avoided collisions may become natural satellites of planets through a process of gravitational capture, or remain in belts of other objects to become either dwarf planets or small bodies. The energetic impacts of the smaller planetesimals (as well as radioactive decay) will heat up the growing planet, causing it to at least partially melt. The interior of the planet begins to differentiate by mass, developing a denser core. Smaller terrestrial planets lose most of their atmospheres because of this accretion, but the lost gases can be replaced by outgassing from the mantle and from the subsequent impact of comets. (Smaller planets will lose any atmosphere they gain through various escape mechanisms.) With the discovery and observation of planetary systems around stars other than the Sun, it is becoming possible to elaborate, revise or even replace this account. The level of metallicity—an astronomical term describing the abundance of chemical elements with an atomic number greater than 2 (helium)—is now thought to determine the likelihood that a star will have planets. Hence, it is thought that a metal-rich population I star will likely have a more substantial planetary system than a metal-poor, population II star. Solar System According to the IAU definition, there are eight planets in the Solar System, which are in increasing distance from the Sun: ☿ Mercury ♀ Venus 🜨 Earth ♂ Mars ♃ Jupiter ♄ Saturn ⛢ Uranus ♆ Neptune Jupiter is the largest, at 318 Earth masses, whereas Mercury is the smallest, at 0.055 Earth masses. The planets of the Solar System can be divided into categories based on their composition: Terrestrials: Planets that are similar to Earth, with bodies largely composed of rock and metal: Mercury, Venus, Earth, and Mars. At 0.055 Earth masses, Mercury is the smallest terrestrial planet (and smallest planet) in the Solar System. Earth is the largest terrestrial planet. Giant planets (Jovians): Massive planets significantly more massive than the terrestrials: Jupiter, Saturn, Uranus, and Neptune. Gas giants: Jupiter and Saturn, are giant planets primarily composed of hydrogen and helium and are the most massive planets in the Solar System. Jupiter, at 318 Earth masses, is the largest planet in the Solar System. Saturn is one third as massive, at 95 Earth masses. Ice giants: Uranus and Neptune, are primarily composed of low-boiling-point materials such as water, methane, and ammonia, with thick atmospheres of hydrogen and helium. They have a significantly lower mass than the gas giants (only 14 and 17 Earth masses). The number of geophysical planets in the Solar System is unknown - previously considered to be potentially in the hundreds, but now only estimated at only the low double digits. These include the eight classical planets, as well as two more populations. Nine objects are generally agreed to be dwarf planets, with some others being disputed candidates.

In increasing order of average distance from the Sun, they are: Ceres is the largest object in the asteroid belt, between the orbits of Mars and Jupiter. The other eight all orbit beyond Neptune.

Gonggong and Eris orbit in the scattered disc, which is somewhat further out and, unlike the Kuiper belt, is unstable towards interactions with Neptune. Sedna is the largest known detached object, a population that never comes close enough to the Sun to interact with any of the classical planets: the origins of their orbits are still being debated.

All of them are smaller than Mercury, with Pluto being the largest known dwarf planet, and Eris being the most massive known. There are also at least nineteen planetary-mass moons or satellite planets, i.e. moons large enough to take on ellipsoidal shapes. The nineteen generally agreed are: One satellite of Earth – the Moon Four satellites of Jupiter – Io, Europa, Ganymede, and Callisto Seven satellites of Saturn – Mimas, Enceladus, Tethys, Dione, Rhea, Titan, and Iapetus Five satellites of Uranus – Miranda, Ariel, Umbriel, Titania, and Oberon One satellite of Neptune – Triton One satellite of Pluto – Charon The Moon, Io, and Europa have compositions similar to the terrestrial planets; the others are made of ice and rock like the dwarf planets, with Tethys being made of almost pure ice. (Europa is often considered an icy planet, though, because its surface ice layer makes it difficult to study its interior.) Ganymede and Titan are larger than Mercury by radius, and Callisto almost equals it, but all three are much less massive. Mimas is the smallest object generally agreed to be a geophysical planet, at about six millionths of Earth's mass, though there are many larger bodies that may not be geophysical planets. Planetary attributes Exoplanets An exoplanet (extrasolar planet) is a planet outside the Solar System. In early 1992, radio astronomers Aleksander Wolszczan and Dale Frail announced the discovery of two planets orbiting the pulsar PSR 1257+12. This discovery was confirmed, and is generally considered to be the first definitive detection of exoplanets. These pulsar planets are believed to have formed from the unusual remnants of the supernova that produced the pulsar, in a second round of planet formation, or else to be the remaining rocky cores of giant planets that survived the supernova and then decayed into their current orbits. The first confirmed discovery of an extrasolar planet orbiting an ordinary main-sequence star occurred on 6 October 1995, when Michel Mayor and Didier Queloz of the University of Geneva announced the detection of an exoplanet around 51 Pegasi.

screens, ran two production studios (in Astoria, New York, now the Kaufman Astoria Studios, and Hollywood, California), and became an early investor in radio, acquiring for the corporation a 50% interest in the new Columbia Broadcasting System in 1928 (selling it within a few years; this would not be the last time Paramount and CBS crossed paths). By acquiring the successful Balaban & Katz chain in 1926, Zukor gained the services of Barney Balaban (who would eventually become Paramount's president in 1936), his brother A. J. Balaban (who would eventually supervise all stage production nationwide and produce talkie shorts), and their partner Sam Katz (who would run the Paramount-Publix theatre chain in New York City from the thirty-five-story Paramount Theatre Building on Times Square). Balaban and Katz had developed the Wonder Theater concept, first publicized around 1918 in Chicago. The Chicago Theater was created as a very ornate theater and advertised as a "wonder theater". When Publix acquired Balaban, they embarked on a project to expand the wonder theaters, and starting building in New York City in 1927. While Balaban and Public were dominant in Chicago, Loew's was the big player in New York City, and did not want the Publix theaters to overshadow theirs. The two companies brokered a non-competition deal for New York City and Chicago, and Loew's took over the New York City area projects, developing five wonder theaters. Publix continued Balaban's wonder theater development in its home area. On April 24, 1930, Paramount-Famous Lasky Corporation became the Paramount Publix Corporation. 1920s and 1931–40: Receivership and reorganization Eventually, Zukor shed most of his early partners; the Frohman brothers, Hodkinson and Goldwyn were out by 1917 while Lasky hung on until 1932, when, blamed for the near-collapse of Paramount in the Great Depression years, he too was tossed out. In 1931, to solve the financial problems of the company Zukor hired John D. Hertz as chairman of the finance committee in order to assist vice-president and treasurer Ralph A. Kohn. However, on January 6, 1933 Hertz resigned from his position when it become evident that his measures to lift the company had failed. The over-expansion and use of overvalued Paramount stock for purchases created a $21 million debt which led the company into receivership on January 26, 1933 and later filing bankruptcy on March 14, 1933. On April 17, 1933, bankruptcy trustees were appointed and Zukor lost control of the company. The company was under the control of trustees for more than a year in order to restructure the debt and pursue a reorganization plan. On December 3, 1934, the reorganization plan was formally proposed. After prolonged hearings in court, final confirmation was obtained on April 25, 1935, when Federal Judge Alfred C. Coxe Jr. approved the reorganization of the Paramount-Publix Corporation under Section 77-B of the Bankruptcy Act. On June 4, 1935 John E. Otterson became president of the re-emerged and newly renamed Paramount Pictures Inc. Zukor returned and was named production chief but after Barney Balaban was appointed president on July 2, 1936, he was soon replaced by Y. Frank Freeman and symbolically named chairman of the board. On August 28, 1935, Paramount Pictures was re-listed on the New York Stock Exchange and when Balaban leaded the company, he was able to successfully relaunch the studio. As always, Paramount films continued to emphasize stars; in the 1920s there were Gloria Swanson, Wallace Reid, Rudolph Valentino, Florence Vidor, Thomas Meighan, Pola Negri, Bebe Daniels, Antonio Moreno, Richard Dix, Esther Ralston, Emil Jannings, George Bancroft, Betty Compson, Clara Bow, Adolphe Menjou, and Charles Buddy Rogers. By the late 1920s and the early 1930s, talkies brought in a range of powerful draws: Richard Arlen, Nancy Carroll, Maurice Chevalier, Gary Cooper, Marlene Dietrich, Charles Ruggles, Ruth Chatterton, William Powell, Mae West, Sylvia Sidney, Bing Crosby, Claudette Colbert, the Marx Brothers, W.C. Fields, Fredric March, Jack Oakie, Jeanette MacDonald (whose first two films were shot at Paramount's Astoria, New York, studio), Carole Lombard, George Raft, Miriam Hopkins, Cary Grant and Stuart Erwin, among them. In this period Paramount can truly be described as a movie factory, turning out sixty to seventy pictures a year. Such were the benefits of having a huge theater chain to fill, and of block booking to persuade other chains to go along. In 1933, Mae West would also add greatly to Paramount's success with her suggestive movies She Done Him Wrong and I'm No Angel. However, the sex appeal West gave in these movies would also lead to the enforcement of the Production Code, as the newly formed organization the Catholic Legion of Decency threatened a boycott if it was not enforced. Paramount cartoons produced by Fleischer Studios continued to be successful, with characters such as Betty Boop and Popeye the Sailor becoming widely successful. One Fleischer series, Screen Songs, featured live-action music stars under contract to Paramount hosting sing-alongs of popular songs. The animation studio would rebound with Popeye, and in 1935, polls showed that Popeye was even more popular than Mickey Mouse. After an unsuccessful expansion into feature films, as well as the fact that Max and Dave Fleischer were no longer speaking to one another, Fleischer Studios was acquired by Paramount, which renamed the operation Famous Studios. That incarnation of the animation studio continued cartoon production until 1967, but has been historically dismissed as having largely failed to maintain the artistic acclaim the Fleischer brothers achieved under their management. 1941–50: United States v. Paramount Pictures, Inc. In 1940, Paramount agreed to a government-instituted consent decree: block booking and "pre-selling" (the practice of collecting up-front money for films not yet in production) would end. Immediately, Paramount cut back on production, from 71 films to a more modest 19 annually in the war years. Still, with more new stars like Bob Hope, Alan Ladd, Veronica Lake, Paulette Goddard, and Betty Hutton, and with war-time attendance at astronomical numbers, Paramount and the other integrated studio-theatre combines made more money than ever. At this, the Federal Trade Commission and the Justice Department decided to reopen their case against the five integrated studios. Paramount also had a monopoly over Detroit movie theaters through subsidiary company United Detroit Theaters. This led to the Supreme Court decision United States v. Paramount Pictures, Inc. (1948) holding that movie studios could not also own movie theater chains. This decision broke up Adolph Zukor's creation, with the theater chain being split into a new company, United Paramount Theaters, and effectively brought an end to the classic Hollywood studio system. 1951–66: Split and after With the separation of production and exhibition forced by the U.S. Supreme Court, Paramount Pictures Inc. was split in two. Paramount Pictures Corporation was formed to be the production distribution company, with the 1,500-screen theater chain handed to the new United Paramount Theaters on December 31, 1949. Leonard Goldenson, who had headed the chain since 1938, remained as the new company's president. The Balaban and Katz theatre division was spun off with UPT; its trademark eventually became the property of the Balaban and Katz Historical Foundation. The Foundation has recently acquired ownership of the Famous Players Trademark. Cash-rich and controlling prime downtown real estate, Goldenson began looking for investments. Barred from film-making by prior antitrust rulings, he acquired the struggling ABC television network in February 1953, leading it first to financial health, and eventually, in the mid-1970s, to first place in the national Nielsen ratings, before selling out to Capital Cities in 1985 (Capital Cities would eventually sell out, in turn, to The Walt Disney Company in 1996). United Paramount Theaters was renamed ABC Theaters in 1965 and was sold to businessman Henry Plitt in 1977. The movie theater chain was renamed Plitt Theaters. In 1985, Cineplex Odeon Corporation merged with Plitt. In later years, Paramount's TV division would develop a strong relationship with ABC, providing many hit series to the network. The DuMont Network Paramount Pictures had been an early backer of television, launching experimental stations in 1939 in Los Angeles and Chicago. The Los Angeles station eventually became KTLA, the first commercial station on the West Coast. The Chicago station got a commercial license as WBKB in 1943, but was sold to UPT along with Balaban & Katz in 1948 and was eventually resold to CBS as WBBM-TV. In 1938, Paramount bought a stake in television manufacturer DuMont Laboratories. Through this stake, it became a minority owner of the DuMont Television Network. Also Paramount launched its own network, Paramount Television Network, in 1948 through its television unit, Television Productions, Inc. Paramount management planned to acquire additional owned-and-operated stations ("O&Os"); the company applied to the FCC for additional stations in San Francisco, Detroit, and Boston. The FCC, however, denied Paramount's applications. A few years earlier, the federal regulator had placed a five-station cap on all television networks: no network was allowed to own more than five VHF television stations. Paramount was hampered by its minority stake in the DuMont Television Network. Although both DuMont and Paramount executives stated that the companies were separate, the FCC ruled that Paramount's partial ownership of DuMont meant that DuMont and Paramount were in theory branches of the same company. Since DuMont owned three television stations and Paramount owned two, the federal agency ruled neither network could acquire additional television stations. The FCC requested that Paramount relinquish its stake in DuMont, but Paramount refused. According to television historian William Boddy, "Paramount's checkered antitrust history" helped convince the FCC that Paramount controlled DuMont. Both DuMont and Paramount Television Network suffered as a result, with neither company able to acquire five O&Os. Meanwhile, CBS, ABC, and NBC had each acquired the maximum of five stations by the mid-1950s. When ABC accepted a merger offer from UPT in 1953, DuMont quickly realized that ABC now had more resources than it could possibly hope to match. It quickly reached an agreement in principle to merge with ABC. However, Paramount vetoed the offer due to antitrust concerns. For all intents and purposes, this was the end of DuMont, though it lingered on until 1956. In 1951, Paramount bought a stake in International Telemeter, an experimental pay TV service which operated with a coin inserted into a box. The service began operating in Palm Springs, California on November 27, 1953, but due to pressure from the FCC, the service ended on May 15, 1954. With the loss of the theater chain, Paramount Pictures went into a decline, cutting studio-backed production, releasing its contract players, and making production deals with independents. By the mid-1950s, all the great names were gone; only Cecil B. DeMille, associated with Paramount since 1913, kept making pictures in the grand old style. Despite Paramount's losses, DeMille would, however, give the studio some relief and create his most successful film at Paramount, a 1956 remake of his 1923 film The Ten Commandments. DeMille died in 1959. Like some other studios, Paramount saw little value in its film library, and sold 764 of its pre-1950 films to MCA Inc./EMKA, Ltd. (known today as Universal Television) in February 1958. 1966–70: Early Gulf+Western era By the early 1960s, Paramount's future was doubtful. The high-risk movie business was wobbly; the theater chain was long gone; investments in DuMont and in early pay-television came to nothing; and the Golden Age of Hollywood had just ended, even the flagship Paramount Building in Times Square was sold to raise cash, as was KTLA (sold to Gene Autry in 1964 for a then-phenomenal $12.5 million). Their only remaining successful property at that point was Dot Records, which Paramount had acquired in 1957, and even its profits started declining by the middle of the 1960s. Founding father Adolph Zukor (born in 1873) was still chairman emeritus; he referred to chairman Barney Balaban (born 1888) as "the boy". Such aged leadership was incapable of keeping up with the changing times, and in 1966, a sinking Paramount was sold to Charles Bluhdorn's industrial conglomerate, Gulf + Western Industries Corporation. Bluhdorn immediately put his stamp on the studio, installing a virtually unknown producer named Robert Evans as head of production. Despite some rough times, Evans held the job for eight years, restoring Paramount's reputation for commercial success with The Odd Couple, Rosemary's Baby, Love Story, The Godfather, Chinatown, and 3 Days of the Condor. Gulf + Western Industries also bought the neighboring Desilu television studio (once the lot of RKO Pictures) from Lucille Ball in 1967. Using some of Desilu's established shows such as Star Trek, Mission: Impossible, and Mannix as a foot in the door at the networks, the newly reincorporated Paramount Television eventually became known as a specialist in half-hour situation comedies. In 1968, Paramount formed Films Distributing Corp to distribute sensitive film product, including Sin With a Stranger, which was one of the first films to receive an X rating in the United States when the MPAA introduced their new rating system. 1971–80: CIC formation and high-concept era In 1970, Paramount teamed with Universal Studios to form Cinema International Corporation, a new company that would distribute films by the two studios outside the United States. Metro-Goldwyn-Mayer would become a partner in the mid-1970s. Both Paramount and CIC entered the video market with Paramount Home Video (now Paramount Home Entertainment) and CIC Video, respectively. Robert Evans abandoned his position as head of production in 1974; his successor, Richard Sylbert, proved to be too literary and too tasteful for Gulf + Western's Bluhdorn. By 1976, a new, television-trained team was in place headed by Barry Diller and his "Killer-Dillers", as they were called by admirers or "Dillettes" as they were called by detractors. These associates, made up of Michael Eisner, Jeffrey Katzenberg, Dawn Steel and Don Simpson would each go on and head up major movie studios of their own later in their careers. The Paramount specialty was now simpler. "high concept" pictures such as Saturday Night Fever and Grease hit big, hit hard and hit fast all over the world, and Diller's television background led him to propose one of his longest-standing ideas to the board: Paramount Television Service, a fourth commercial network. Paramount Pictures purchased the Hughes Television Network (HTN) including its satellite time in planning for PTVS in 1976. Paramount sold HTN to Madison Square Garden in 1979. But Diller believed strongly in the concept, and so took his fourth-network idea with him when he moved to 20th Century Fox in 1984, where Fox's then freshly installed proprietor, Rupert Murdoch was a more interested listener. However, the television division would be playing catch-up for over a decade after Diller's departure in 1984 before launching its own television network – UPN – in 1995. Lasting eleven years before being merged with The WB network to become The CW in 2006, UPN would feature many of the shows it originally produced for other networks, and would take numerous gambles on series such as Star Trek: Voyager and Star Trek: Enterprise that would have otherwise either gone direct-to-cable or become first-run syndication to independent stations across the country (as Star Trek: Deep Space Nine and Star Trek: The Next Generation were). Paramount Pictures was not connected to either Paramount Records (1910s–1935) or ABC-Paramount Records (1955–66) until it purchased the rights to use the name (but not the latter's catalog) in the late 1960s. The Paramount name was used for soundtrack albums and some pop re-issues from the Dot Records catalog which Paramount had acquired in 1957. By 1970, Dot had become an all-country label and in 1974, Paramount sold all of its record holdings to ABC Records, which in turn was sold to MCA (now Universal Music Group) in 1979. 1980–94: Continual success Paramount's successful run of pictures extended into the 1980s and 1990s, generating hits like Airplane!, American Gigolo, Ordinary People, An Officer and a Gentleman, Flashdance, Terms of Endearment, Footloose, Pretty in Pink, Top Gun, Crocodile Dundee, Fatal Attraction, Ghost, the Friday the 13th slasher series, as well as teaming up with Lucasfilm to create the Indiana Jones franchise. Other examples are the Star Trek film series and a string of films starring comedian Eddie Murphy like Trading Places, Coming to America and Beverly Hills Cop and its sequels. While the emphasis was decidedly on the commercial, there were occasional less commercial but more artistic and intellectual efforts like I'm Dancing as Fast as I Can, Atlantic City, Reds, Witness, Children of a Lesser God and The Accused. During this period, responsibility for running the studio passed from Eisner and Katzenberg to Frank Mancuso, Sr. (1984) and Ned Tanen (1984) to Stanley R. Jaffe (1991) and Sherry Lansing (1992). More so than most, Paramount's slate of films included many remakes and television spin-offs; while sometimes commercially successful, there have been few compelling films of the kind that once made Paramount the industry leader. On August 25, 1983, Paramount Studios caught fire. Two or three sound stages and four outdoor sets were destroyed. When Charles Bluhdorn died unexpectedly, his successor Martin Davis dumped all of G+W's industrial, mining, and sugar-growing subsidiaries and refocused the company, renaming it Paramount Communications in 1989. With the influx of cash from the sale of G+W's industrial properties in the mid-1980s, Paramount | nickelodeons, saw that movies appealed mainly to working-class immigrants. With partners Daniel Frohman and Charles Frohman he planned to offer feature-length films that would appeal to the middle class by featuring the leading theatrical players of the time (leading to the slogan "Famous Players in Famous Plays"). By mid-1913, Famous Players had completed five films, and Zukor was on his way to success. Its first film was Les Amours de la reine Élisabeth, which starred Sarah Bernhardt. That same year, another aspiring producer, Jesse L. Lasky, opened his Lasky Feature Play Company with money borrowed from his brother-in-law, Samuel Goldfish, later known as Samuel Goldwyn. The Lasky company hired as their first employee a stage director with virtually no film experience, Cecil B. DeMille, who would find a suitable site in Hollywood. This place was a rented old horse barn converted into a production facility with an enlarged open-air stage located between Vine Street, Selma Avenue, Argyle Avenue and Sunset Boulevard. It was later known as the Lasky-DeMille Barn. In 1914, their first feature film, The Squaw Man was released. On May 8, 1914, Paramount Pictures Corporation (previously known as Progressive Pictures) was founded by a Utah theatre owner, W. W. Hodkinson, who had bought and merged five smaller firms. On May 15, 1914, Hodkinson signed a five-year contract with the Famous Players Film Company, the Lasky Company and Bosworth, Inc. to distribute their films. Actor, director and producer Hobart Bosworth had started production of a series of Jack London movies. Paramount was the first successful nationwide distributor; until this time, films were sold on a statewide or regional basis which had proved costly to film producers. Also, Famous Players and Lasky were privately owned while Paramount was a corporation. Famous Players-Lasky In 1916, Zukor engineered a three-way merger of his Famous Players, the Lasky Company, and Paramount. Zukor and Lasky bought Hodkinson out of Paramount, and merged the three companies into one. The new company Lasky and Zukor founded on June 28, Famous Players-Lasky Corporation, although it continued to use the name "Paramount" as well. As a result, it became he largest film company at the time with a value of $12.5 million. The corporation was able to grow quickly, with Lasky and his partners Goldwyn and DeMille running the production side, Hiram Abrams in charge of distribution, and Zukor making great plans. With only the exhibitor-owned First National as a rival, Famous Players-Lasky and its "Paramount Pictures" soon dominated the business. The fusion was finalized on November 7, 1916. Because Zukor believed in stars, he signed and developed many of the leading early stars, including Mary Pickford, Marguerite Clark, Pauline Frederick, Douglas Fairbanks, Gloria Swanson, Rudolph Valentino, and Wallace Reid. With so many important players, Paramount was able to introduce "block booking", which meant that an exhibitor who wanted a particular star's films had to buy a year's worth of other Paramount productions. It was this system that gave Paramount a leading position in the 1920s and 1930s, but which led the government to pursue it on antitrust grounds for more than twenty years. By the mid-1920s, the old Lasky-DeMille barn property was not big enough to handle all of the studios' West Coast productions. In January 5, 1926 Lasky reached an agreement to buy the Robert Brunton Studios, a 26-acre facility owned by United Pictures and located at 5451 Marathon Street, for US$1 million. On March 29, the company began an eight-month building program to renovate the existing facilities and erect new ones. On May 8, Lasky finally moved operations from the Sunset and Vine lot to the new building. At present, those facilities are still part of the Paramount Pictures headquarters. Zukor hired independent producer B. P. Schulberg, an unerring eye for new talent, to run the new West Coast operations. On April 1, 1927, the company name was changed to Paramount Famous Lasky Corporation. In September 1927, the Paramount Famous Lasky Corporation studio in Astoria (New York City) was temporarily closed with the objective of equipping it with the technology for the production of sound films. In the same year, Paramount began releasing Inkwell Imps, animated cartoons produced by Max and Dave Fleischer's Fleischer Studios in New York City. The Fleischers, veterans in the animation industry, were among the few animation producers capable of challenging the prominence of Walt Disney. The Paramount newsreel series Paramount News ran from 1927 to 1957. Paramount was also one of the first Hollywood studios to release what were known at that time as "talkies", and in 1929, released their first musical, Innocents of Paris. Richard A. Whiting and Leo Robin composed the score for the film; Maurice Chevalier starred and sung the most famous song from the film, "Louise". Publix, Balaban and Katz, Loew's competition and wonder theaters The driving force behind Paramount's rise was Zukor. He built a chain of nearly 2,000 screens, ran two production studios (in Astoria, New York, now the Kaufman Astoria Studios, and Hollywood, California), and became an early investor in radio, acquiring for the corporation a 50% interest in the new Columbia Broadcasting System in 1928 (selling it within a few years; this would not be the last time Paramount and CBS crossed paths). By acquiring the successful Balaban & Katz chain in 1926, Zukor gained the services of Barney Balaban (who would eventually become Paramount's president in 1936), his brother A. J. Balaban (who would eventually supervise all stage production nationwide and produce talkie shorts), and their partner Sam Katz (who would run the Paramount-Publix theatre chain in New York City from the thirty-five-story Paramount Theatre Building on Times Square). Balaban and Katz had developed the Wonder Theater concept, first publicized around 1918 in Chicago. The Chicago Theater was created as a very ornate theater and advertised as a "wonder theater". When Publix acquired Balaban, they embarked on a project to expand the wonder theaters, and starting building in New York City in 1927. While Balaban and Public were dominant in Chicago, Loew's was the big player in New York City, and did not want the Publix theaters to overshadow theirs. The two companies brokered a non-competition deal for New York City and Chicago, and Loew's took over the New York City area projects, developing five wonder theaters. Publix continued Balaban's wonder theater development in its home area. On April 24, 1930, Paramount-Famous Lasky Corporation became the Paramount Publix Corporation. 1920s and 1931–40: Receivership and reorganization Eventually, Zukor shed most of his early partners; the Frohman brothers, Hodkinson and Goldwyn were out by 1917 while Lasky hung on until 1932, when, blamed for the near-collapse of Paramount in the Great Depression years, he too was tossed out. In 1931, to solve the financial problems of the company Zukor hired John D. Hertz as chairman of the finance committee in order to assist vice-president and treasurer Ralph A. Kohn. However, on January 6, 1933 Hertz resigned from his position when it become evident that his measures to lift the company had failed. The over-expansion and use of overvalued Paramount stock for purchases created a $21 million debt which led the company into receivership on January 26, 1933 and later filing bankruptcy on March 14, 1933. On April 17, 1933, bankruptcy trustees were appointed and Zukor lost control of the company. The company was under the control of trustees for more than a year in order to restructure the debt and pursue a reorganization plan. On December 3, 1934, the reorganization plan was formally proposed. After prolonged hearings in court, final confirmation was obtained on April 25, 1935, when Federal Judge Alfred C. Coxe Jr. approved the reorganization of the Paramount-Publix Corporation under Section 77-B of the Bankruptcy Act. On June 4, 1935 John E. Otterson became president of the re-emerged and newly renamed Paramount Pictures Inc. Zukor returned and was named production chief but after Barney Balaban was appointed president on July 2, 1936, he was soon replaced by Y. Frank Freeman and symbolically named chairman of the board. On August 28, 1935, Paramount Pictures was re-listed on the New York Stock Exchange and when Balaban leaded the company, he was able to successfully relaunch the studio. As always, Paramount films continued to emphasize stars; in the 1920s there were Gloria Swanson, Wallace Reid, Rudolph Valentino, Florence Vidor, Thomas Meighan, Pola Negri, Bebe Daniels, Antonio Moreno, Richard Dix, Esther Ralston, Emil Jannings, George Bancroft, Betty Compson, Clara Bow, Adolphe Menjou, and Charles Buddy Rogers. By the late 1920s and the early 1930s, talkies brought in a range of powerful draws: Richard Arlen, Nancy Carroll, Maurice Chevalier, Gary Cooper, Marlene Dietrich, Charles Ruggles, Ruth Chatterton, William Powell, Mae West, Sylvia Sidney, Bing Crosby, Claudette Colbert, the Marx Brothers, W.C. Fields, Fredric March, Jack Oakie, Jeanette MacDonald (whose first two films were shot at Paramount's Astoria, New York, studio), Carole Lombard, George Raft, Miriam Hopkins, Cary Grant and Stuart Erwin, among them. In this period Paramount can truly be described as a movie factory, turning out sixty to seventy pictures a year. Such were the benefits of having a huge theater chain to fill, and of block booking to persuade other chains to go along. In 1933, Mae West would also add greatly to Paramount's success with her suggestive movies She Done Him Wrong and I'm No Angel. However, the sex appeal West gave in these movies would also lead to the enforcement of the Production Code, as the newly formed organization the Catholic Legion of Decency threatened a boycott if it was not enforced. Paramount cartoons produced by Fleischer Studios continued to be successful, with characters such as Betty Boop and Popeye the Sailor becoming widely successful. One Fleischer series, Screen Songs, featured live-action music stars under contract to Paramount hosting sing-alongs of popular songs. The animation studio would rebound with Popeye, and in 1935, polls showed that Popeye was even more popular than Mickey Mouse. After an unsuccessful expansion into feature films, as well as the fact that Max and Dave Fleischer were no longer speaking to one another, Fleischer Studios was acquired by Paramount, which renamed the operation Famous Studios. That incarnation of the animation studio continued cartoon production until 1967, but has been historically dismissed as having largely failed to maintain the artistic acclaim the Fleischer brothers achieved under their management. 1941–50: United States v. Paramount Pictures, Inc. In 1940, Paramount agreed to a government-instituted consent decree: block booking and "pre-selling" (the practice of collecting up-front money for films not yet in production) would end.

By 1970, Dot had become an all-country label and in 1974, Paramount sold all of its record holdings to ABC Records, which in turn was sold to MCA (now Universal Music Group) in 1979. 1980–94: Continual success Paramount's successful run of pictures extended into the 1980s and 1990s, generating hits like Airplane!, American Gigolo, Ordinary People, An Officer and a Gentleman, Flashdance, Terms of Endearment, Footloose, Pretty in Pink, Top Gun, Crocodile Dundee, Fatal Attraction, Ghost, the Friday the 13th slasher series, as well as teaming up with Lucasfilm to create the Indiana Jones franchise. Other examples are the Star Trek film series and a string of films starring comedian Eddie Murphy like Trading Places, Coming to America and Beverly Hills Cop and its sequels. While the emphasis was decidedly on the commercial, there were occasional less commercial but more artistic and intellectual efforts like I'm Dancing as Fast as I Can, Atlantic City, Reds, Witness, Children of a Lesser God and The Accused. During this period, responsibility for running the studio passed from Eisner and Katzenberg to Frank Mancuso, Sr. (1984) and Ned Tanen (1984) to Stanley R. Jaffe (1991) and Sherry Lansing (1992). More so than most, Paramount's slate of films included many remakes and television spin-offs; while sometimes commercially successful, there have been few compelling films of the kind that once made Paramount the industry leader. On August 25, 1983, Paramount Studios caught fire. Two or three sound stages and four outdoor sets were destroyed. When Charles Bluhdorn died unexpectedly, his successor Martin Davis dumped all of G+W's industrial, mining, and sugar-growing subsidiaries and refocused the company, renaming it Paramount Communications in 1989. With the influx of cash from the sale of G+W's industrial properties in the mid-1980s, Paramount bought a string of television stations and KECO Entertainment's theme park operations, renaming them Paramount Parks. These parks included Paramount's Great America, Paramount Canada's Wonderland, Paramount's Carowinds, Paramount's Kings Dominion, and Paramount's Kings Island. In May 1985, Paramount decided to start its own talent department, establishing which its feature directors could draw, which the studio decided to shut down on July 30, 1986, by then-studio president Dawn Steel. In 1993, Sumner Redstone's entertainment conglomerate Viacom made a bid for a merger with Paramount Communications; this quickly escalated into a bidding war with Barry Diller's QVC. But Viacom prevailed, ultimately paying $10 billion for the Paramount holdings. Viacom and Paramount had planned to merge as early as 1989. Paramount is the last major film studio located in Hollywood proper. When Paramount moved to its present home in 1927, it was in the heart of the film community. Since then, former next-door neighbor RKO closed up shop in 1957 (Paramount ultimately absorbed their former lot); Warner Bros. (whose old Sunset Boulevard studio was sold to Paramount in 1949 as a home for KTLA) moved to Burbank in 1930; Columbia joined Warners in Burbank in 1973 then moved again to Culver City in 1989; and the Pickford-Fairbanks-Goldwyn-United Artists lot, after a lively history, has been turned into a post-production and music-scoring facility for Warners, known simply as "The Lot". For a time the semi-industrial neighborhood around Paramount was in decline, but has now come back. The recently refurbished studio has come to symbolize Hollywood for many visitors, and its studio tour is a popular attraction. 1989–94: Paramount Communications In 1983, Gulf and Western began a restructuring process that would transform the corporation from a bloated conglomerate consisting of subsidiaries from unrelated industries to a more focused entertainment and publishing company. The idea was to aid financial markets in measuring the company's success, which, in turn, would help place better value on its shares. Though its Paramount division did very well in recent years, Gulf and Western's success as a whole was translating poorly with investors. This process eventually led Davis to divest many of the company's subsidiaries. Its sugar plantations in Florida and the Dominican Republic were sold in 1985; the consumer and industrial products branch was sold off that same year. In 1989, Davis renamed the company Paramount Communications Incorporated after its primary asset, Paramount Pictures. In addition to the Paramount film, television, home video, and music publishing divisions, the company continued to own the Madison Square Garden properties (which also included MSG Network), a 50% stake in USA Networks (the other 50% was owned by MCA/Universal Studios) and Simon & Schuster, Prentice Hall, Pocket Books, Allyn & Bacon, Cineamerica (a joint venture with Warner Communications), and Canadian cinema chain Famous Players Theatres. That same year, the company launched a $12.2 billion hostile bid to acquire Time Inc. in an attempt to end a stock-swap merger deal between Time and Warner Communications. This caused Time to raise its bid for Warner to $14.9 billion in cash and stock. Gulf and Western responded by filing a lawsuit |
Psychologists in 1959. Several associations including the Association of Black Psychologists and the Asian American Psychological Association have arisen to promote the inclusion of non-European racial groups in the profession. The International Union of Psychological Science (IUPsyS) is the world federation of national psychological societies. The IUPsyS was founded in 1951 under the auspices of the United Nations Educational, Cultural and Scientific Organization (UNESCO). Psychology departments have since proliferated around the world, based primarily on the Euro-American model. Since 1966, the Union has published the International Journal of Psychology. IAAP and IUPsyS agreed in 1976 each to hold a congress every four years, on a staggered basis. IUPsyS recognizes 66 national psychology associations and at least 15 others exist. The American Psychological Association is the oldest and largest. Its membership has increased from 5,000 in 1945 to 100,000 in the present day. The APA includes 54 divisions, which since 1960 have steadily proliferated to include more specialties. Some of these divisions, such as the Society for the Psychological Study of Social Issues and the American Psychology–Law Society, began as autonomous groups. The Interamerican Psychological Society, founded in 1951, aspires to promote psychology across the Western Hemisphere. It holds the Interamerican Congress of Psychology and ha had 1,000 members in year 2000. The European Federation of Professional Psychology Associations, founded in 1981, represents 30 national associations with a total of 100,000 individual members. At least 30 other international organizations represent psychologists in different regions. In some places, governments legally regulate who can provide psychological services or represent themselves as a "psychologist." The APA defines a psychologist as someone with a doctoral degree in psychology. Boundaries Early practitioners of experimental psychology distinguished themselves from parapsychology, which in the late nineteenth century enjoyed popularity (including the interest of scholars such as William James). Some people considered parapsychology to be part of "psychology." Parapsychology, hypnotism, and psychism were major topics at the early International Congresses. But students of these fields were eventually ostracized, and more or less banished from the Congress in 1900–1905. Parapsychology persisted for a time at Imperial University in Japan, with publications such as Clairvoyance and Thoughtography by Tomokichi Fukurai, but it was mostly shunned by 1913. As a discipline, psychology has long sought to fend off accusations that it is a "soft" science. Philosopher of science Thomas Kuhn's 1962 critique implied psychology overall was in a pre-paradigm state, lacking agreement on the type of overarching theory found in mature sciences such as chemistry and physics. Because some areas of psychology rely on research methods such as surveys and questionnaires, critics asserted that psychology is not an objective science. Skeptics have suggested that personality, thinking, and emotion cannot be directly measured and are often inferred from subjective self-reports, which may be problematic. Experimental psychologists have devised a variety of ways to indirectly measure these elusive phenomenological entities. Divisions still exist within the field, with some psychologists more oriented towards the unique experiences of individual humans, which cannot be understood only as data points within a larger population. Critics inside and outside the field have argued that mainstream psychology has become increasingly dominated by a "cult of empiricism," which limits the scope of research because investigators restrict themselves to methods derived from the physical sciences. Feminist critiques have argued that claims to scientific objectivity obscure the values and agenda of (historically) mostly male researchers. Jean Grimshaw, for example, argues that mainstream psychological research has advanced a patriarchal agenda through its efforts to control behavior. Major schools of thought Biological Psychologists generally consider biology the substrate of thought and feeling, and therefore an important area of study. Behaviorial neuroscience, also known as biological psychology, involves the application of biological principles to the study of physiological and genetic mechanisms underlying behavior in humans and other animals. The allied field of comparative psychology is the scientific study of the behavior and mental processes of non-human animals. A leading question in behavioral neuroscience has been whether and how mental functions are localized in the brain. From Phineas Gage to H.M. and Clive Wearing, individual people with mental deficits traceable to physical brain damage have inspired new discoveries in this area. Modern behavioral neuroscience could be said to originate in the 1870s, when in France Paul Broca traced production of speech to the left frontal gyrus, thereby also demonstrating hemispheric lateralization of brain function. Soon after, Carl Wernicke identified a related area necessary for the understanding of speech. The contemporary field of behavioral neuroscience focuses on the physical basis of behavior. Behaviorial neuroscientists use animal models, often relying on rats, to study the neural, genetic, and cellular mechanisms that underlie behaviors involved in learning, memory, and fear responses. Cognitive neuroscientists, by using neural imaging tools, investigate the neural correlates of psychological processes in humans. Neuropsychologists conduct psychological assessments to determine how an individual's behavior and cognition are related to the brain. The biopsychosocial model is a cross-disciplinary, holistic model that concerns the ways in which interrelationships of biological, psychological, and socio-environmental factors affect health and behavior. Evolutionary psychology approaches thought and behavior from a modern evolutionary perspective. This perspective suggests that psychological adaptations evolved to solve recurrent problems in human ancestral environments. Evolutionary psychologists attempt to find out how human psychological traits are evolved adaptations, the results of natural selection or sexual selection over the course of human evolution. The history of the biological foundations of psychology includes evidence of racism. The idea of white supremacy and indeed the modern concept of race itself arose during the process of world conquest by Europeans. Carl von Linnaeus's four-fold classification of humans classifies Europeans as intelligent and severe, Americans as contented and free, Asians as ritualistic, and Africans as lazy and capricious. Race was also used to justify the construction of socially specific mental disorders such as drapetomania and dysaesthesia aethiopica—the behavior of uncooperative African slaves. After the creation of experimental psychology, "ethnical psychology" emerged as a subdiscipline, based on the assumption that studying primitive races would provide an important link between animal behavior and the psychology of more evolved humans. Behavioral A tenet of behavioral research is that a large part of both human and lower-animal behavior is learned. A principle associated with behavioral research is that the mechanisms involved in learning apply to humans and non-human animals. Behavioral researchers have developed a treatment known as behavior modification, which is used to help individuals replace undesirable behaviors with desirable ones. Early behavioral researchers studied stimulus–response pairings, now known as classical conditioning. They demonstrated that when a biologically potent stimulus (e.g., food that elicits salivation) is paired with a previously neutral stimulus (e.g., a bell) over several learning trials, the neutral stimulus by itself can come to elicit the response the biologically potent stimulus elicits. Ivan Pavlov—known best for inducing dogs to salivate in the presence of a stimulus previously linked with food—became a leading figure in the Soviet Union and inspired followers to use his methods on humans. In the United States, Edward Lee Thorndike initiated "connectionist" studies by trapping animals in "puzzle boxes" and rewarding them for escaping. Thorndike wrote in 1911, "There can be no moral warrant for studying man's nature unless the study will enable us to control his acts." From 1910 to 1913 the American Psychological Association went through a sea change of opinion, away from mentalism and towards "behavioralism." In 1913, John B. Watson coined the term behaviorism for this school of thought. Watson's famous Little Albert experiment in 1920 was at first thought to demonstrate that repeated use of upsetting loud noises could instill phobias (aversions to other stimuli) in an infant human, although such a conclusion was likely an exaggeration. Karl Lashley, a close collaborator with Watson, examined biological manifestations of learning in the brain. Clark L. Hull, Edwin Guthrie, and others did much to help behaviorism become a widely used paradigm. A new method of "instrumental" or "operant" conditioning added the concepts of reinforcement and punishment to the model of behavior change. Radical behaviorists avoided discussing the inner workings of the mind, especially the unconscious mind, which they considered impossible to assess scientifically. Operant conditioning was first described by Miller and Kanorski and popularized in the U.S. by B.F. Skinner, who emerged as a leading intellectual of the behaviorist movement. Noam Chomsky published an influential critique of radical behaviorism on the grounds that behaviorist principles could not adequately explain the complex mental process of language acquisition and language use. The review, which was scathing, did much to reduce the status of behaviorism within psychology. Martin Seligman and his colleagues discovered that they could condition "learned helplessness" in dogs, a state that was not predicted by the behaviorist approach to psychology. Edward C. Tolman advanced a hybrid "cognitive behavioral" model, most notably with his 1948 publication discussing the cognitive maps used by rats to guess at the location of food at the end of a maze. Skinner's behaviorism did not die, in part because it generated successful practical applications. The Association for Behavior Analysis International was founded in 1974 and by 2003 had members from 42 countries. The field has gained a foothold in Latin America and Japan. Applied behavior analysis is the term used for the application of the principles of operant conditioning to change socially significant behavior (it supersedes the term behavior modification). Cognitive Green Red BluePurple Blue Purple Blue Purple RedGreen Purple Green The Stroop effect is the fact that naming the color of the first set of words is easier and quicker than the second. Cognitive psychology involves the study of mental processes, including perception, attention, language comprehension and production, memory, and problem solving. Researchers in the field of cognitive psychology are sometimes called cognitivists. They rely on an information processing model of mental functioning. Cognitivist research is informed by functionalism and experimental psychology. Starting in the 1950s, the experimental techniques developed by Wundt, James, Ebbinghaus, and others re-emerged as experimental psychology became increasingly cognitivist and, eventually, constituted a part of the wider, interdisciplinary cognitive science. Some called this development the cognitive revolution because it rejected the anti-mentalist dogma of behaviorism as well as the strictures of psychoanalysis. Albert Bandura helped along the transition in psychology from behaviorism to cognitive psychology. Bandura and other social learning theorists advanced the idea of vicarious learning. In other words, they advanced the view that a child can learn by observing his or her social environment and not necessarily from having been reinforced for enacting a behavior, although they did not rule out the influence of reinforcement on learning a behavior. Technological advances also renewed interest in mental states and mental representations. English neuroscientist Charles Sherrington and Canadian psychologist Donald O. Hebb used experimental methods to link psychological phenomena to the structure and function of the brain. The rise of computer science, cybernetics, and artificial intelligence underlined the value of comparing information processing in humans and machines. A popular and representative topic in this area is cognitive bias, or irrational thought. Psychologists (and economists) have classified and described a sizeable catalogue of biases which recur frequently in human thought. The availability heuristic, for example, is the tendency to overestimate the importance of something which happens to come readily to mind. Elements of behaviorism and cognitive psychology were synthesized to form cognitive behavioral therapy, a form of psychotherapy modified from techniques developed by American psychologist Albert Ellis and American psychiatrist Aaron T. Beck. On a broader level, cognitive science is an interdisciplinary enterprise involving cognitive psychologists, cognitive neuroscientists, linguists, and researchers in artificial intelligence, human–computer interaction, and computational neuroscience. The discipline of cognitive science covers cognitive psychology as well as philosophy of mind, computer science, and neuroscience. Computer simulations are sometimes used to model phenomena of interest. Social Social psychology is concerned with how behaviors, thoughts, feelings, and the social environment influence human interactions. Social psychologists study such topics as the influence of others on an individual's behavior (e.g. conformity, persuasion) and the formation of beliefs, attitudes, and stereotypes about other people. Social cognition fuses elements of social and cognitive psychology for the purpose of understanding how people process, remember, or distort social information. The study of group dynamics involves research on the nature of leadership, organizational communication, and related phenomena. In recent years, social psychologists have become interested in implicit measures, mediational models, and the interaction of person and social factors in accounting for behavior. Some concepts that sociologists have applied to the study of psychiatric disorders, concepts such as the social role, sick role, social class, life events, culture, migration, and total institution, have influenced social psychologists. Psychoanalytic Psychoanalysis refers to the theories and therapeutic techniques applied to the unconscious mind and its impact on everyday life. These theories and techniques inform treatments for mental disorders. Psychoanalysis originated in the 1890s, most prominently with the work of Sigmund Freud. Freud's psychoanalytic theory was largely based on interpretive methods, introspection, and clinical observation. It became very well known, largely because it tackled subjects such as sexuality, repression, and the unconscious. Freud pioneered the methods of free association and dream interpretation. Psychoanalytic theory is not monolithic. Other well known psychoanalytic thinkers who diverged with Freud include Alfred Adler, Carl Jung, Erik Erikson, Melanie Klein, D.W. Winnicott, Karen Horney, Erich Fromm, John Bowlby, Freud's daughter Anna Freud, and Harry Stack Sullivan. These individuals ensured that psychoanalysis would evolve into diverse schools of thought. Among these schools are ego psychology, object relations, and interpersonal, Lacanian, and relational psychoanalysis. Psychologists such as Hans Eysenck and philosophers including Karl Popper sharply criticized psychoanalysis. Popper argued that psychoanalysis had been misrepresented as a scientific discipline, whereas Eysenck advanced the view that psychoanalytic tenets had been contradicted by experimental data. By the end of the 20th century, psychology departments in American universities mostly marginalized Freudian theory, dismissing it as a "desiccated and dead" historical artifact. Researchers such as António Damásio, Oliver Sacks, and Joseph LeDoux, and individuals in the emerging field of neuro-psychoanalysis, have defended some of Freud's ideas on scientific grounds. Existential-humanistic theories Humanistic psychology, which has been influenced by existentialism and phenomenology, stresses free will and self-actualization. It emerged in the 1950s as a movement within academic psychology, in reaction to both behaviorism and psychoanalysis. The humanistic approach seeks to view the whole person, not just fragmented parts of the personality or isolated cognitions. Humanistic psychology also focuses on personal growth, self-identity, death, aloneness, and freedom. It emphasizes subjective meaning, the rejection of determinism, and concern for positive growth rather than pathology. Some founders of the humanistic school of thought were American psychologists Abraham Maslow, who formulated a hierarchy of human needs, and Carl Rogers, who created and developed client-centered therapy. Later, positive psychology opened up humanistic themes to scientific study. Positive psychology is the study of factors which contribute to human happiness and well-being, focusing more on people who are currently healthy. In 2010, Clinical Psychological Review published a special issue devoted to positive psychological interventions, such as gratitude journaling and the physical expression of gratitude. It is, however, far from clear that positive psychology is effective in making people happier. Positive psychological interventions have been limited in scope, but their effects are thought to be somewhat better than placebo effects. The evidence, however, is far from clear that interventions based on positive psychology increase human happiness or resilience. The American Association for Humanistic Psychology, formed in 1963, declared: Existential psychology emphasizes the need to understand a client's total orientation towards the world. Existential psychology is opposed to reductionism, behaviorism, and other methods that objectify the individual. In the 1950s and 1960s, influenced by philosophers Søren Kierkegaard and Martin Heidegger, psychoanalytically trained American psychologist Rollo May helped to develop existential psychology. Existential psychotherapy, which follows from existential psychology, is a therapeutic approach that is based on the idea that a person's inner conflict arises from that individual's confrontation with the givens of existence. Swiss psychoanalyst Ludwig Binswanger and American psychologist George Kelly may also be said to belong to the existential school. Existential psychologists tend to differ from more "humanistic" psychologists in the former's relatively neutral view of human nature and relatively positive assessment of anxiety. Existential psychologists emphasized the humanistic themes of death, free will, and meaning, suggesting that meaning can be shaped by myths and narratives; meaning can be deepened by the acceptance of free will, which is requisite to living an authentic life, albeit often with anxiety with regard to death. Austrian existential psychiatrist and Holocaust survivor Viktor Frankl drew evidence of meaning's therapeutic power from reflections upon his own internment. He created a variation of existential psychotherapy called logotherapy, a type of existentialist analysis that focuses on a will to meaning (in one's life), as opposed to Adler's Nietzschean doctrine of will to power or Freud's will to pleasure. Themes Personality Personality psychology is concerned with enduring patterns of behavior, thought, and emotion. Theories of personality vary across different psychological schools of thought. Each theory carries different assumptions about such features as the role of the unconscious and the importance of childhood experience. According to Freud, personality is based on the dynamic interactions of the id, ego, and super-ego. By contrast, trait theorists have developed taxonomies of personality constructs in describing personality in terms of key traits. Trait theorists have often employed statistical data-reduction methods, such as factor analysis. Although the number of proposed traits has varied widely, Hans Eysenck's early biologically-based model suggests at least three major trait constructs are necessary to describe human personality, extraversion–introversion, neuroticism-stability, and psychoticism-normality. Raymond Cattell empirically derived a theory of 16 personality factors at the primary-factor level and up to eight broader second-stratum factors. Since the 1980s, the Big Five (openness to experience, conscientiousness, extraversion, agreeableness, and neuroticism) emerged as an important trait theory of personality. Dimensional models of personality are receiving increasing support, and a version of dimensional assessment has been included in the DSM-V. However, despite a plethora of research into the various versions of the "Big Five" personality dimensions, it appears necessary to move on from static conceptualizations of personality structure to a more dynamic orientation, acknowledging that personality constructs are subject to learning and change over the lifespan. An early example of personality assessment was the Woodworth Personal Data Sheet, constructed during World War I. The popular, although psychometrically inadequate, Myers–Briggs Type Indicator was developed to assess individuals' "personality types" according to the personality theories of Carl Jung. The Minnesota Multiphasic Personality Inventory (MMPI), despite its name, is more a dimensional measure of psychopathology than a personality measure. California Psychological Inventory contains 20 personality scales (e.g., independence, tolerance). The International Personality Item Pool, which is in the public domain, has become a source of scales that can be used personality assessment. Unconscious mind Study of the unconscious mind, a part of the psyche outside the individual's awareness but that is believed to influence conscious thought and behavior, was a hallmark of early psychology. In one of the first psychology experiments conducted in the United States, C.S. Peirce and Joseph Jastrow found in 1884 that research subjects could choose the minutely heavier of two weights even if consciously uncertain of the difference. Freud popularized the concept of the unconscious mind, particularly when he referred to an uncensored intrusion of unconscious thought into one's speech (a Freudian slip) or to his efforts to interpret dreams. His 1901 book The Psychopathology of Everyday Life catalogues hundreds of everyday events that Freud explains in terms of unconscious influence. Pierre Janet advanced the idea of a subconscious mind, which could contain autonomous mental elements unavailable to the direct scrutiny of the subject. The concept of unconscious processes has remained important in psychology. Cognitive psychologists have used a "filter" model of attention. According to the model, much information processing takes place below the threshold of consciousness, and only certain stimuli, limited by their nature and number, make their way through the filter. Much research has shown that subconscious priming of certain ideas can covertly influence thoughts and behavior. Because of the unreliability of self-reporting, a major hurdle in this type of research involves demonstrating that a subject's conscious mind has not perceived a target stimulus. For this reason, some psychologists prefer to distinguish between implicit and explicit memory. In another approach, one can also describe a subliminal stimulus as meeting an objective but not a subjective threshold. The automaticity model of John Bargh and others involves the ideas of automaticity and unconscious processing in our understanding of social behavior, although there has been dispute with regard to replication. Some experimental data suggest that the brain begins to consider taking actions before the mind becomes aware of them. The influence of unconscious forces on people's choices bears on the philosophical question of free will. John Bargh, Daniel Wegner, and Ellen Langer describe free will as an illusion. Motivation Some psychologists study motivation or the subject of why people or lower animals initiate a behavior at a particular time. It also involves the study of why humans and lower animals continue or terminate a behavior. Psychologists such as William James initially used the term motivation to refer to intention, in a sense similar to the concept of will in European philosophy. With the steady rise of Darwinian and Freudian thinking, instinct also came to be seen as a primary source of motivation. According to drive theory, the forces of instinct combine into a single source of energy which exerts a constant influence. Psychoanalysis, like biology, regarded these forces as demands originating in the nervous system. Psychoanalysts believed that these forces, especially the sexual instincts, could become entangled and transmuted within the psyche. Classical psychoanalysis conceives of a struggle between the pleasure principle and the reality principle, roughly corresponding to id and ego. Later, in Beyond the Pleasure Principle, Freud introduced the concept of the death drive, a compulsion towards aggression, destruction, and psychic repetition of traumatic events. Meanwhile, behaviorist researchers used simple dichotomous models (pleasure/pain, reward/punishment) and well-established principles such as the idea that a thirsty creature will take pleasure in drinking. Clark Hull formalized the latter idea with his drive reduction model. Hunger, thirst, fear, sexual desire, and thermoregulation constitute fundamental motivations in animals. Humans seem to exhibit a more complex set of motivations—though theoretically these could be explained as resulting from desires for belonging, positive self-image, self-consistency, truth, love, and control. Motivation can be modulated or manipulated in many different ways. Researchers have found that eating, for example, depends not only on the organism's fundamental need for homeostasis—an important factor causing the experience of hunger—but also on circadian rhythms, food availability, food palatability, and cost. Abstract motivations are also malleable, as evidenced by such phenomena as goal contagion: the adoption of goals, sometimes unconsciously, based on inferences about the goals of others. Vohs and Baumeister suggest that contrary to the need-desire-fulfilment cycle of animal instincts, human motivations sometimes obey a "getting begets wanting" rule: the more you get a reward such as self-esteem, love, drugs, or money, the more you want it. They suggest that this principle can even apply to food, drink, sex, and sleep. Development psychology Developmental psychology refers to the scientific study of how and why the thought processes, emotions, and behaviors of humans change over the course of their lives. Some credit Charles Darwin with conducting the first systematic study within the rubric of developmental psychology, having published in 1877 a short paper detailing the development of innate forms of communication based on his observations of his infant son. The main origins of the discipline, however, are found in the work of Jean Piaget. Like Piaget, developmental psychologists originally focused primarily on the development of cognition from infancy to adolescence. Later, developmental psychology extended itself to the study cognition over the life span. In addition to studying cognition, developmental psychologists have also come to focus on affective, behavioral, moral, social, and neural development. Developmental psychologists who study children use a number of research methods. For example, they make observations of children in natural settings such as preschools and engage them in experimental tasks. Such tasks often resemble specially designed games and activities that are both enjoyable for the child and scientifically useful. Developmental researchers have even devised clever methods to study the mental processes of infants. In addition to studying children, developmental psychologists also study aging and processes throughout the life span, including old age. These psychologists draw on the full range of psychological theories to inform their research. Genes and environment All researched psychological traits are influenced by both genes and environment, to varying degrees. These two sources of influence are often confounded in observational research of individuals and families. An example of this confounding can be shown in the transmission of depression | clinic in the United States typically goes to Lightner Witmer, who established his practice in Philadelphia in 1896. Another modern psychotherapist was Morton Prince, an early advocate for the establishment of psychology as a clinical and academic discipline. In the first part of the twentieth century, most mental health care in the United States was performed by psychiatrists, who are medical doctors. Psychology entered the field with its refinements of mental testing, which promised to improve the diagnosis of mental problems. For their part, some psychiatrists became interested in using psychoanalysis and other forms of psychodynamic psychotherapy to understand and treat the mentally ill. Psychotherapy as conducted by psychiatrists blurred the distinction between psychiatry and psychology, and this trend continued with the rise of community mental health facilities. Some in the clinical psychology community adopted behavioral therapy, a thoroughly non-psychodynamic model that used behaviorist learning theory to change the actions of patients. A key aspect of behavior therapy is empirical evaluation of the treatment's effectiveness. In the 1970s, cognitive-behavior therapy emerged with the work of Albert Ellis and Aaron Beck. Although there are similarities between behavior therapy and cognitive-behavior therapy, cognitive-behavior therapy required the application of cognitive constructs. Since the 1970s, the popularity of cognitive-behavior therapy among clinical psychologists increased. A key practice in behavioral and cognitive-behavioral therapy is exposing patients to things they fear, based on the premise that their responses (fear, panic, anxiety) can be deconditioned. Mental health care today involves psychologists and social workers in increasing numbers. In 1977, National Institute of Mental Health director Bertram Brown described this shift as a source of "intense competition and role confusion." Graduate programs issuing doctorates in clinical psychology emerged in the 1950s and underwent rapid increase through the 1980s. The PhD degree is intended to train practitioners who could also conduct scientific research. The PsyD degree is more exclusively designed to train practitioners. Some clinical psychologists focus on the clinical management of patients with brain injury. This subspecialty is known as clinical neuropsychology. In many countries, clinical psychology is a regulated mental health profession. The emerging field of disaster psychology (see crisis intervention) involves professionals who respond to large-scale traumatic events. The work performed by clinical psychologists tends to be influenced by various therapeutic approaches, all of which involve a formal relationship between professional and client (usually an individual, couple, family, or small group). Typically, these approaches encourage new ways of thinking, feeling, or behaving. Four major theoretical perspectives are psychodynamic, cognitive behavioral, existential–humanistic, and systems or family therapy. There has been a growing movement to integrate the various therapeutic approaches, especially with an increased understanding of issues regarding culture, gender, spirituality, and sexual orientation. With the advent of more robust research findings regarding psychotherapy, there is evidence that most of the major therapies have equal effectiveness, with the key common element being a strong therapeutic alliance. Because of this, more training programs and psychologists are now adopting an eclectic therapeutic orientation. Diagnosis in clinical psychology usually follows the Diagnostic and Statistical Manual of Mental Disorders (DSM). The study of mental illnesses is called abnormal psychology. Education Educational psychology is the study of how humans learn in educational settings, the effectiveness of educational interventions, the psychology of teaching, and the social psychology of schools as organizations. Educational psychologists can be found in preschools, schools of all levels including post secondary institutions, community organizations and learning centers, Government or private research firms, and independent or private consultant [[Madisonodell5/sandbox]]. The work of developmental psychologists such as Lev Vygotsky, Jean Piaget, and Jerome Bruner has been influential in creating teaching methods and educational practices. Educational psychology is often included in teacher education programs in places such as North America, Australia, and New Zealand. School psychology combines principles from educational psychology and clinical psychology to understand and treat students with learning disabilities; to foster the intellectual growth of gifted students; to facilitate prosocial behaviors in adolescents; and otherwise to promote safe, supportive, and effective learning environments. School psychologists are trained in educational and behavioral assessment, intervention, prevention, and consultation, and many have extensive training in research. Work Industrial and organizational (I/O) psychology involves research and practices that apply psychological theories and principles to organizations and individuals' work-lives. In the field's beginnings, industrialists brought the nascent field of psychology to bear on the study of scientific management techniques for improving workplace efficiency. The field was at first called economic psychology or business psychology; later, industrial psychology, employment psychology, or psychotechnology. An influential early study examined workers at Western Electric's Hawthorne plant in Cicero, Illinois from 1924 to 1932. Western Electric experimented on factory workers to assess their responses to changes in illumination, breaks, food, and wages. The researchers came to focus on workers' responses to observation itself, and the term Hawthorne effect is now used to describe the fact that people work harder when they think they're being watched. Although the Hawthorne research can be found in psychology textbooks, the research and its findings, however, were weak at best. The name industrial and organizational psychology emerged in the 1960s. In 1973, it became enshrined in the name of the Society for Industrial and Organizational Psychology, Division 14 of the American Psychological Association. One goal of the discipline is to optimize human potential in the workplace. Personnel psychology is a subfield of I/O psychology. Personnel psychologists apply the methods and principles of psychology in selecting and evaluating workers. Another subfield, organizational psychology, examines the effects of work environments and management styles on worker motivation, job satisfaction, and productivity. Most I/O psychologists work outside of academia, for private and public organizations and as consultants. A psychology consultant working in business today might expect to provide executives with information and ideas about their industry, their target markets, and the organization of their company. Organizational behavior (OB) is an allied field involved in the study of human behavior within organizations. One way to differentiate I/O psychology from OB is to note that I/O psychologists train in university psychology departments and OB specialists, in business schools. Military and intelligence One role for psychologists in the military has been to evaluate and counsel soldiers and other personnel. In the U.S., this function began during World War I, when Robert Yerkes established the School of Military Psychology at Fort Oglethorpe in Georgia. The school provided psychological training for military staff. Today, U.S. Army psychologists perform psychological screening, clinical psychotherapy, suicide prevention, and treatment for post-traumatic stress, as well as provide prevention-related services, for example, smoking cessation. The United States Army's Mental Health Advisory Teams implement psychological interventions to help combat troops experiencing mental problems. Psychologists may also work on a diverse set of campaigns known broadly as psychological warfare. Psychological warfare chiefly involves the use of propaganda to influence enemy soldiers and civilians. This so-called black propaganda is designed to seem as if it originates from a source other than the Army. The CIA's MKULTRA program involved more individualized efforts at mind control, involving techniques such as hypnosis, torture, and covert involuntary administration of LSD. The U.S. military used the name Psychological Operations (PSYOP) until 2010, when these activities were reclassified as Military Information Support Operations (MISO), part of Information Operations (IO). Psychologists have sometimes been involved in assisting the interrogation and torture of suspects, staining the records of the psychologists involved. Health, well-being, and social change Social change An example of the contribution of psychologists to social change involves the research of Kenneth and Mamie Clark. These two African American psychologists studied segregation's adverse psychological impact on Black children. Their research findings played a role in the desegregation case Brown v. Board of Education (1954). The impact of psychology on social change includes the discipline's broad influence on teaching and learning. Research has shown that compared to the "whole word" or "whole language" approach, the phonics approach to reading instruction is more efficacious. Medical applications Medical facilities increasingly employ psychologists to perform various roles. One aspect of health psychology is the psychoeducation of patients: instructing them in how to follow a medical regimen. Health psychologists can also educate doctors and conduct research on patient compliance. Psychologists in the field of public health use a wide variety of interventions to influence human behavior. These range from public relations campaigns and outreach to governmental laws and policies. Psychologists study the composite influence of all these different tools in an effort to influence whole populations of people. Worker health, safety and wellbeing Psychologists work with organizations to apply findings from psychological research to improve the health and well-being of employees. Some work as external consultants hired by organizations to solve specific problems, whereas others are full-time employees of the organization. Applications include conducting surveys to identify issues and designing interventions to make work healthier. Some of the specific health areas include: Accidents and injuries: A major contribution is the concept of safety climate, which is employee shared perceptions of the behaviors that are encouraged (e.g., wearing safety gear) and discouraged (not following safety rules) at work. Organizations with strong safety climates have fewer work accidents and injuries. Cardiovascular disease: Cardiovascular disease has been related to lack of job control. Mental health: Exposure to occupational stress is associated with mental health disorder. Musculoskeletal disorder: These are injuries in bones, nerves and tendons due to overexertion and repetitive strain. They have been linked to job satisfaction and workplace stress. Physical health symptoms: Occupational stress has been linked to physical symptoms such as digestive distress and headache. Workplace violence: Violence prevention climate is related to being physically assaulted and psychologically mistreated at work. Interventions that improve climates are a way to address accidents and violence. Interventions that reduce stress at work or provide employees with tools to better manage it can help in areas where stress is an important component. Industrial psychology became interested in worker fatigue during World War I, when government ministers in Britain were concerned about the impact of fatigue on workers in munitions factories but not other types of factories. In the U. K. some interest in worker well-being emerged with the efforts of Charles Samuel Myers and his National Institute of Industrial Psychology (NIIP) during the inter-War years. In the U. S. during the mid-twentieth century industrial psychologist Arthur Kornhauser pioneered the study of occupational mental health, linking industrial working conditions to mental health as well as the spillover of an unsatisfying job into a worker's personal life. Zickar accumulated evidence to show that "no other industrial psychologist of his era was as devoted to advocating management and labor practices that would improve the lives of working people." Occupational health psychology As interest in the worker health expanded toward the end of the twentieth century, the field of occupational health psychology (OHP) emerged. OHP is a branch of psychology that is interdisciplinary. OHP is concerned with the health and safety of workers. OHP addresses topic areas such as the impact of occupational stressors on physical and mental health, mistreatment of workers (e.g., bullying and violence), work-family balance, the impact of involuntary unemployment on physical and mental health, the influence of psychosocial factors on safety and accidents, and interventions designed to improve/protect worker health. OHP grew out of health psychology, industrial and organizational psychology, and occupational medicine. OHP has also been informed by disciplines outside psychology, including industrial engineering, sociology, and economics. Research methods Quantitative psychological research lends itself to the statistical testing of hypotheses. Although the field makes abundant use of randomized and controlled experiments in laboratory settings, such research can only assess a limited range of short-term phenomena. Some psychologists rely on less rigorously controlled, but more ecologically valid, field experiments as well. Other research psychologists rely on statistical methods to glean knowledge from population data. The statistical methods research psychologists employ include the Pearson product–moment correlation coefficient, the analysis of variance, multiple linear regression, logistic regression, structural equation modeling, and hierarchical linear modeling. The measurement and operationalization of important constructs is an essential part of these research designs. Although this type of psychological research is much less abundant than quantitative research, some psychologists conduct qualitative research. This type of research can involve interviews, questionnaires, and first-hand observation. While hypothesis testing is rare, virtually impossible, in qualitative research, qualitative studies can be helpful in theory and hypothesis generation, interpreting seemingly contradictory quantitative findings, and understanding why some interventions fail and others succeed. Controlled experiments A true experiment with random assignment of research participants (sometimes called subjects) to rival conditions allows researchers to make strong inferences about causal relationships. When there are large numbers of research participants, the random assignment (also called random allocation) of those participants to rival conditions ensures that the individuals in those conditions will, on average, be similar on most characteristics, including characteristics that went unmeasured. In an experiment, the researcher alters one or more variables of influence, called independent variables, and measures resulting changes in the factors of interest, called dependent variables. Prototypical experimental research is conducted in a laboratory with a carefully controlled environment. A quasi-experiment refers to a situation in which there are rival conditions under study but random assignment to the different conditions is not possible. Investigators must work with preexisting groups of people. Researchers can use common sense to consider how much the nonrandom assignment threatens the study's validity. For example, in research on the best way to affect reading achievement in the first three grades of school, school administrators may not permit educational psychologists to randomly assign children to phonics and whole language classrooms, in which case the psychologists must work with preexisting classroom assignments. Psychologists will compare the achievement of children attending phonics and whole language classes and, perhaps, statistically adjust for any initial differences in reading level. Experimental researchers typically use a statistical hypothesis testing model which involves making predictions before conducting the experiment, then assessing how well the data collected are consistent with the predictions. These predictions are likely to originate from one or more abstract scientific hypotheses about how the phenomenon under study actually works. Other types of studies Surveys are used in psychology for the purpose of measuring attitudes and traits, monitoring changes in mood, and checking the validity of experimental manipulations (checking research participants' perception of the condition they were assigned to). Psychologists have commonly used paper-and-pencil surveys. However, surveys are also conducted over the phone or through e-mail. Web-based surveys are increasingly used to conveniently reach many subjects. Observational studies are commonly conducted in psychology. In cross-sectional observational studies, psychologists collect data at a single point in time. The goal of many cross-sectional studies is the assess the extent factors are correlated with each other. By contrast, in longitudinal studies psychologists collect data on the same sample at two or more points in time. Sometimes the purpose of longitudinal research is to study trends across time such as the stability of traits or age-related changes in behavior. Because some studies involve endpoints that psychologists cannot ethically study from an experimental standpoint, such as identifying the causes of depression, they conduct longitudinal studies a large group of depression-free people, periodically assessing what is happening in the individuals' lives. In this way psychologists have an opportunity to test causal hypotheses regarding conditions that commonly arise in people's lives that put them at risk for depression. Problems that affect longitudinal studies include selective attrition, the type of problem in which bias is introduced when a certain type of research participant disproportionately leaves a study. Exploratory data analysis refers to a variety of practices that researchers use to reduce a great many variables to a small number overarching factors. In Peirce's three modes of inference, exploratory data analysis corresponds to abduction. Meta-analysis is the technique research psychologists use to integrate results from many studies of the same variables and arriving at a grand average of the findings. Direct brain observation/manipulaiton A classic and popular tool used to relate mental and neural activity is the electroencephalogram (EEG), a technique using amplified electrodes on a person's scalp to measure voltage changes in different parts of the brain. Hans Berger, the first researcher to use EEG on an unopened skull, quickly found that brains exhibit signature "brain waves": electric oscillations which correspond to different states of consciousness. Researchers subsequently refined statistical methods for synthesizing the electrode data, and identified unique brain wave patterns such as the delta wave observed during non-REM sleep. Newer functional neuroimaging techniques include functional magnetic resonance imaging and positron emission tomography, both of which track the flow of blood through the brain. These technologies provide more localized information about activity in the brain and create representations of the brain with widespread appeal. They also provide insight which avoids the classic problems of subjective self-reporting. It remains challenging to draw hard conclusions about where in the brain specific thoughts originate—or even how usefully such localization corresponds with reality. However, neuroimaging has delivered unmistakable results showing the existence of correlations between mind and brain. Some of these draw on a systemic neural network model rather than a localized function model. Psychiatric interventions such as transcranial magnetic stimulation and drugs also provide information about brain–mind interactions. Psychopharmacology is the study of drug-induced mental effects. Computer simulation Computational modeling is a tool used in mathematical psychology and cognitive psychology to simulate behavior. This method has several advantages. Since modern computers process information quickly, simulations can be run in a short time, allowing for high statistical power. Modeling also allows psychologists to visualize hypotheses about the functional organization of mental events that couldn't be directly observed in a human. Computational neuroscience uses mathematical models to simulate the brain. Another method is symbolic modeling, which represents many mental objects using variables and rules. Other types of modeling include dynamic systems and stochastic modeling. Animal studies Animal experiments aid in investigating many aspects of human psychology, including perception, emotion, learning, memory, and thought, to name a few. In the 1890s, Russian physiologist Ivan Pavlov famously used dogs to demonstrate classical conditioning. Non-human primates, cats, dogs, pigeons, and rats and other rodents are often used in psychological experiments. Ideally, controlled experiments introduce only one independent variable at a time, in order to ascertain its unique effects upon dependent variables. These conditions are approximated best in laboratory settings. In contrast, human environments and genetic backgrounds vary so widely, and depend upon so many factors, that it is difficult to control important variables for human subjects. There are pitfalls, however, in generalizing findings from animal studies to humans through animal models. Comparative psychology refers to the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior. Research in this area explores the behavior of many species, from insects to primates. It is closely related to other disciplines that study animal behavior such as ethology. Research in comparative psychology sometimes appears to shed light on human behavior, but some attempts to connect the two have been quite controversial, for example the Sociobiology of E.O. Wilson. Animal models are often used to study neural processes related to human behavior, e.g. in cognitive neuroscience. Qualitative research Qualitative research is often designed to answer questions about the thoughts, feelings, and behaviors of individuals. Qualitative research involving first-hand observation can help describe events as they occur, with the goal of capturing the richness of everyday behavior and with the hope of discovering and understanding phenomena that might have been missed if only more cursory examinations are made. Qualitative psychological research methods include interviews, first-hand observation, and participant observation. Creswell (2003) identified five main possibilities for qualitative research, including narrative, phenomenology, ethnography, case study, and grounded theory. Qualitative researchers sometimes aim to enrich our understanding of symbols, subjective experiences, or social structures. Sometimes hermeneutic and critical aims can give rise to quantitative research, as in Erich Fromm's application of psychological and sociological theories, in his book Escape from Freedom, to understanding why many ordinary Germans supported Hitler. Just as Jane Goodall studied chimpanzee social and family life by careful observation of chimpanzee behavior in the field, psychologists conduct naturalistic observation of ongoing human social, professional, and family life. Sometimes the participants are aware they are being observed, and other times the participants do not know they are being observed. Strict ethical guidelines must be followed when covert observation is being carried out. Program evaluation Program evaluation involves the systematic collection, analysis, and application of information to answer questions about projects, policies and programs, particularly about their effectiveness. In both the public and private sectors, stakeholders often want to know the extent which the programs they are funding, implementing, voting for, receiving, or objecting to are producing the intended effects. While program evaluation first focuses on effectiveness, important considerations often include how much the program costs per participant, how the program could be improved, whether the program is worthwhile, whether there are better alternatives, if there are unintended outcomes, and whether the program goals are appropriate and useful. Contemporary issues in methodology and practice Metascience Metascience involves the application of scientific methodology to study science itself. The field of metascience has revealed problems in psychological research. Some psychological research has suffered from bias, problematic reproducibility, and misuse of statistics. These findings have led to calls for reform from within and from outside the scientific community. Confirmation bias In 1959, statistician Theodore Sterling examined the results of psychological studies and discovered that |

character as archaic. Rhyme consists of identical ("hard-rhyme") or similar ("soft-rhyme") sounds placed at the ends of lines or at predictable locations within lines ("internal rhyme"). Languages vary in the richness of their rhyming structures; Italian, for example, has a rich rhyming structure permitting maintenance of a limited set of rhymes throughout a lengthy poem. The richness results from word endings that follow regular forms. English, with its irregular word endings adopted from other languages, is less rich in rhyme. The degree of richness of a language's rhyming structures plays a substantial role in determining what poetic forms are commonly used in that language. Alliteration is the repetition of letters or letter-sounds at the beginning of two or more words immediately succeeding each other, or at short intervals; or the recurrence of the same letter in accented parts of words. Alliteration and assonance played a key role in structuring early Germanic, Norse and Old English forms of poetry. The alliterative patterns of early Germanic poetry interweave meter and alliteration as a key part of their structure, so that the metrical pattern determines when the listener expects instances of alliteration to occur. This can be compared to an ornamental use of alliteration in most Modern European poetry, where alliterative patterns are not formal or carried through full stanzas. Alliteration is particularly useful in languages with less rich rhyming structures. Assonance, where the use of similar vowel sounds within a word rather than similar sounds at the beginning or end of a word, was widely used in skaldic poetry but goes back to the Homeric epic. Because verbs carry much of the pitch in the English language, assonance can loosely evoke the tonal elements of Chinese poetry and so is useful in translating Chinese poetry. Consonance occurs where a consonant sound is repeated throughout a sentence without putting the sound only at the front of a word. Consonance provokes a more subtle effect than alliteration and so is less useful as a structural element. Rhyming schemes In many languages, including modern European languages and Arabic, poets use rhyme in set patterns as a structural element for specific poetic forms, such as ballads, sonnets and rhyming couplets. However, the use of structural rhyme is not universal even within the European tradition. Much modern poetry avoids traditional rhyme schemes. Classical Greek and Latin poetry did not use rhyme. Rhyme entered European poetry in the High Middle Ages, in part under the influence of the Arabic language in Al Andalus (modern Spain). Arabic language poets used rhyme extensively from the first development of literary Arabic in the sixth century, as in their long, rhyming qasidas. Some rhyming schemes have become associated with a specific language, culture or period, while other rhyming schemes have achieved use across languages, cultures or time periods. Some forms of poetry carry a consistent and well-defined rhyming scheme, such as the chant royal or the rubaiyat, while other poetic forms have variable rhyme schemes. Most rhyme schemes are described using letters that correspond to sets of rhymes, so if the first, second and fourth lines of a quatrain rhyme with each other and the third line do not rhyme, the quatrain is said to have an "aa-ba" rhyme scheme. This rhyme scheme is the one used, for example, in the rubaiyat form. Similarly, an "a-bb-a" quatrain (what is known as "enclosed rhyme") is used in such forms as the Petrarchan sonnet. Some types of more complicated rhyming schemes have developed names of their own, separate from the "a-bc" convention, such as the ottava rima and terza rima. The types and use of differing rhyming schemes are discussed further in the main article. Form in poetry Poetic form is more flexible in modernist and post-modernist poetry and continues to be less structured than in previous literary eras. Many modern poets eschew recognizable structures or forms and write in free verse. Free verse is, however, not "formless" but composed of a series of more subtle, more flexible prosodic elements. Thus poetry remains, in all its styles, distinguished from prose by form; some regard for basic formal structures of poetry will be found in all varieties of free verse, however much such structures may appear to have been ignored. Similarly, in the best poetry written in classic styles there will be departures from strict form for emphasis or effect. Among major structural elements used in poetry are the line, the stanza or verse paragraph, and larger combinations of stanzas or lines such as cantos. Also sometimes used are broader visual presentations of words and calligraphy. These basic units of poetic form are often combined into larger structures, called poetic forms or poetic modes (see the following section), as in the sonnet. Lines and stanzas Poetry is often separated into lines on a page, in a process known as lineation. These lines may be based on the number of metrical feet or may emphasize a rhyming pattern at the ends of lines. Lines may serve other functions, particularly where the poem is not written in a formal metrical pattern. Lines can separate, compare or contrast thoughts expressed in different units, or can highlight a change in tone. See the article on line breaks for information about the division between lines. Lines of poems are often organized into stanzas, which are denominated by the number of lines included. Thus a collection of two lines is a couplet (or distich), three lines a triplet (or tercet), four lines a quatrain, and so on. These lines may or may not relate to each other by rhyme or rhythm. For example, a couplet may be two lines with identical meters which rhyme or two lines held together by a common meter alone. Other poems may be organized into verse paragraphs, in which regular rhymes with established rhythms are not used, but the poetic tone is instead established by a collection of rhythms, alliterations, and rhymes established in paragraph form. Many medieval poems were written in verse paragraphs, even where regular rhymes and rhythms were used. In many forms of poetry, stanzas are interlocking, so that the rhyming scheme or other structural elements of one stanza determine those of succeeding stanzas. Examples of such interlocking stanzas include, for example, the ghazal and the villanelle, where a refrain (or, in the case of the villanelle, refrains) is established in the first stanza which then repeats in subsequent stanzas. Related to the use of interlocking stanzas is their use to separate thematic parts of a poem. For example, the strophe, antistrophe and epode of the ode form are often separated into one or more stanzas. In some cases, particularly lengthier formal poetry such as some forms of epic poetry, stanzas themselves are constructed according to strict rules and then combined. In skaldic poetry, the dróttkvætt stanza had eight lines, each having three "lifts" produced with alliteration or assonance. In addition to two or three alliterations, the odd-numbered lines had partial rhyme of consonants with dissimilar vowels, not necessarily at the beginning of the word; the even lines contained internal rhyme in set syllables (not necessarily at the end of the word). Each half-line had exactly six syllables, and each line ended in a trochee. The arrangement of dróttkvætts followed far less rigid rules than the construction of the individual dróttkvætts. Visual presentation Even before the advent of printing, the visual appearance of poetry often added meaning or depth. Acrostic poems conveyed meanings in the initial letters of lines or in letters at other specific places in a poem. In Arabic, Hebrew and Chinese poetry, the visual presentation of finely calligraphed poems has played an important part in the overall effect of many poems. With the advent of printing, poets gained greater control over the mass-produced visual presentations of their work. Visual elements have become an important part of the poet's toolbox, and many poets have sought to use visual presentation for a wide range of purposes. Some Modernist poets have made the placement of individual lines or groups of lines on the page an integral part of the poem's composition. At times, this complements the poem's rhythm through visual caesuras of various lengths, or creates juxtapositions so as to accentuate meaning, ambiguity or irony, or simply to create an aesthetically pleasing form. In its most extreme form, this can lead to concrete poetry or asemic writing. Diction Poetic diction treats the manner in which language is used, and refers not only to the sound but also to the underlying meaning and its interaction with sound and form. Many languages and poetic forms have very specific poetic dictions, to the point where distinct grammars and dialects are used specifically for poetry. Registers in poetry can range from strict employment of ordinary speech patterns, as favoured in much late-20th-century prosody, through to highly ornate uses of language, as in medieval and Renaissance poetry. Poetic diction can include rhetorical devices such as simile and metaphor, as well as tones of voice, such as irony. Aristotle wrote in the Poetics that "the greatest thing by far is to be a master of metaphor." Since the rise of Modernism, some poets have opted for a poetic diction that de-emphasizes rhetorical devices, attempting instead the direct presentation of things and experiences and the exploration of tone. On the other hand, Surrealists have pushed rhetorical devices to their limits, making frequent use of catachresis. Allegorical stories are central to the poetic diction of many cultures, and were prominent in the West during classical times, the late Middle Ages and the Renaissance. Aesop's Fables, repeatedly rendered in both verse and prose since first being recorded about 500 BCE, are perhaps the richest single source of allegorical poetry through the ages. Other notables examples include the Roman de la Rose, a 13th-century French poem, William Langland's Piers Ploughman in the 14th century, and Jean de la Fontaine's Fables (influenced by Aesop's) in the 17th century. Rather than being fully allegorical, however, a poem may contain symbols or allusions that deepen the meaning or effect of its words without constructing a full allegory. Another element of poetic diction can be the use of vivid imagery for effect. The juxtaposition of unexpected or impossible images is, for example, a particularly strong element in surrealist poetry and haiku. Vivid images are often endowed with symbolism or metaphor. Many poetic dictions use repetitive phrases for effect, either a short phrase (such as Homer's "rosy-fingered dawn" or "the wine-dark sea") or a longer refrain. Such repetition can add a somber tone to a poem, or can be laced with irony as the context of the words changes. Forms Specific poetic forms have been developed by many cultures. In more developed, closed or "received" poetic forms, the rhyming scheme, meter and other elements of a poem are based on sets of rules, ranging from the relatively loose rules that govern the construction of an elegy to the highly formalized structure of the ghazal or villanelle. Described below are some common forms of poetry widely used across a number of languages. Additional forms of poetry may be found in the discussions of the poetry of particular cultures or periods and in the glossary. Sonnet Among the most common forms of poetry, popular from the Late Middle Ages on, is the sonnet, which by the 13th century had become standardized as fourteen lines following a set rhyme scheme and logical structure. By the 14th century and the Italian Renaissance, the form had further crystallized under the pen of Petrarch, whose sonnets were translated in the 16th century by Sir Thomas Wyatt, who is credited with introducing the sonnet form into English literature. A traditional Italian or Petrarchan sonnet follows the rhyme scheme ABBA, ABBA, CDECDE, though some variation, perhaps the most common being CDCDCD, especially within the final six lines (or sestet), is common. The English (or Shakespearean) sonnet follows the rhyme scheme ABAB, CDCD, EFEF, GG, introducing a third quatrain (grouping of four lines), a final couplet, and a greater amount of variety with regard to rhyme than is usually found in its Italian predecessors. By convention, sonnets in English typically use iambic pentameter, while in the Romance languages, the hendecasyllable and Alexandrine are the most widely used meters. Sonnets of all types often make use of a volta, or "turn," a point in the poem at which an idea is turned on its head, a question is answered (or introduced), or the subject matter is further complicated. This volta can often take the form of a "but" statement contradicting or complicating the content of the earlier lines. In the Petrarchan sonnet, the turn tends to fall around the division between the first two quatrains and the sestet, while English sonnets usually place it at or near the beginning of the closing couplet. Sonnets are particularly associated with high poetic diction, vivid imagery, and romantic love, largely due to the influence of Petrarch as well as of early English practitioners such as Edmund Spenser (who gave his name to the Spenserian sonnet), Michael Drayton, and Shakespeare, whose sonnets are among the most famous in English poetry, with twenty being included in the Oxford Book of English Verse. However, the twists and turns associated with the volta allow for a logical flexibility applicable to many subjects. Poets from the earliest centuries of the sonnet to the present have utilized the form to address topics related to politics (John Milton, Percy Bysshe Shelley, Claude McKay), theology (John Donne, Gerard Manley Hopkins), war (Wilfred Owen, e.e. cummings), and gender and sexuality (Carol Ann Duffy). Further, postmodern authors such as Ted Berrigan and John Berryman have challenged the traditional definitions of the sonnet form, rendering entire sequences of "sonnets" that often lack rhyme, a clear logical progression, or even a consistent count of fourteen lines. Shi Shi () Is the main type of Classical Chinese poetry. Within this form of poetry the most important variations are "folk song" styled verse (yuefu), "old style" verse (gushi), "modern style" verse (jintishi). In all cases, rhyming is obligatory. The Yuefu is a folk ballad or a poem written in the folk ballad style, and the number of lines and the length of the lines could be irregular. For the other variations of shi poetry, generally either a four line (quatrain, or jueju) or else an eight-line poem is normal; either way with the even numbered lines rhyming. The line length is scanned by an according number of characters (according to the convention that one character equals one syllable), and are predominantly either five or seven characters long, with a caesura before the final three syllables. The lines are generally end-stopped, considered as a series of couplets, and exhibit verbal parallelism as a key poetic device. The "old style" verse (Gushi) is less formally strict than the jintishi, or regulated verse, which, despite the name "new style" verse actually had its theoretical basis laid as far back as Shen Yue (441–513 CE), although not considered to have reached its full development until the time of Chen Zi'ang (661–702 CE). A good example of a poet known for his Gushi poems is Li Bai (701–762 CE). Among its other rules, the jintishi rules regulate the tonal variations within a poem, including the use of set patterns of the four tones of Middle Chinese. The basic form of jintishi (sushi) has eight lines in four couplets, with parallelism between the lines in the second and third couplets. The couplets with parallel lines contain contrasting content but an identical grammatical relationship between words. Jintishi often have a rich poetic diction, full of allusion, and can have a wide range of subject, including history and politics. One of the masters of the form was Du Fu (712–770 CE), who wrote during the Tang Dynasty (8th century). Villanelle The villanelle is a nineteen-line poem made up of five triplets with a closing quatrain; the poem is characterized by having two refrains, initially used in the first and third lines of the first stanza, and then alternately used at the close of each subsequent stanza until the final quatrain, which is concluded by the two refrains. The remaining lines of the poem have an a-b alternating rhyme. The villanelle has been used regularly in the English language since the late 19th century by such poets as Dylan Thomas, W. H. Auden, and Elizabeth Bishop. Limerick A limerick is a poem that consists of five lines and is often humorous. Rhythm is very important in limericks for the first, second and fifth lines must have seven to ten syllables. However, the third and fourth lines only need five to seven. All of the lines must rhyme and have the same rhythm. Practitioners of the limerick included Edward Lear, Lord Alfred Tennyson, Rudyard Kipling, Robert Louis Stevenson. Tanka Tanka is a form of unrhymed Japanese poetry, with five sections totalling 31 on (phonological units identical to morae), structured in a 5-7-5-7-7 pattern. There is generally a shift in tone and subject matter between the upper 5-7-5 phrase and the lower 7-7 phrase. Tanka were written as early as the Asuka period by such poets as Kakinomoto no Hitomaro (fl. late 7th century), at a time when Japan was emerging from a period where much of its poetry followed Chinese form. Tanka was originally the shorter form of Japanese formal poetry (which was generally referred to as "waka"), and was used more heavily to explore personal rather than public themes. By the tenth century, tanka had become the dominant form of Japanese poetry, to the point where the originally general term waka ("Japanese poetry") came to be used exclusively for tanka. Tanka are still widely written today. Haiku Haiku is a popular form of unrhymed Japanese poetry, which evolved in the 17th century from the hokku, or opening verse of a renku. Generally written in a single vertical line, the haiku contains three sections totalling 17 on (morae), structured in a 5-7-5 pattern. Traditionally, haiku contain a kireji, or cutting word, usually placed at the end of one of the poem's three sections, and a kigo, or season-word. The most famous exponent of the haiku was Matsuo Bashō (1644–1694). An example of his writing: fuji no kaze ya oogi ni nosete Edo miyage the wind of Mt. Fuji I've brought on my fan! a gift from Edo Khlong The khlong (, ) is among the oldest Thai poetic forms. This is reflected in its requirements on the tone markings of certain syllables, which must be marked with mai ek (, , ) or mai tho (, , ). This was likely derived from when the Thai language had three tones (as opposed to today's five, a split which occurred during the Ayutthaya Kingdom period), two of which corresponded directly to the aforementioned marks. It is usually regarded as an advanced and sophisticated poetic form. In khlong, a stanza (bot, , ) has a number of lines (bat, , , from Pali and Sanskrit pāda), depending on the type. The bat are subdivided into two wak (, , from Sanskrit varga). The first wak has five syllables, the second has a variable number, also depending on the type, and may be optional. The type of khlong is named by the number of bat in a stanza; it may also be divided into two main types: khlong suphap (, ) and khlong dan (, ). The two differ in the number of syllables in the second wak of the final bat and inter-stanza rhyming rules. Khlong si suphap The khlong si suphap (, ) is the most common form still currently employed. It has four bat per stanza (si translates as four). The first wak of each bat has five syllables. The second wak has two or four syllables in the first and third bat, two syllables in the second, and four syllables in the fourth. Mai ek is required for seven syllables and Mai tho is required for four, as shown below. "Dead word" syllables are allowed in place of syllables which require mai ek, and changing the spelling of words to satisfy the criteria is usually acceptable. Ode Odes were first developed by poets writing in ancient Greek, such as Pindar, and Latin, such as Horace. Forms of odes appear in many of the cultures that were influenced by the Greeks and Latins. The ode generally has three parts: a strophe, an antistrophe, and an epode. The strophe and the antistrophe of the ode possess similar metrical structures and, depending on the tradition, similar rhyme structures. In contrast, the epode is written with a different scheme and structure. Odes have a formal poetic diction and generally deal with a serious subject. The strophe and antistrophe look at the subject from different, often conflicting, perspectives, with the epode moving to a higher level to either view or resolve the underlying issues. Odes are often intended to be recited or sung by two choruses (or individuals), with the first reciting the strophe, the second the antistrophe, and both together the epode. Over time, differing forms for odes have developed with considerable variations in form and structure, but generally showing the original influence of the Pindaric or Horatian ode. One non-Western form which resembles the ode is the qasida in Persian poetry. Ghazal The (also , , , or ) is a form of poetry common in Arabic, Bengali, Persian and Urdu. In classic form, the has from five to fifteen rhyming couplets that share a refrain at the end of the second line. This refrain may be of one or several syllables and is preceded by a rhyme. Each line has an identical meter. The often reflects on a theme of unattainable love or divinity. As with other forms with a long history in many languages, many variations have been developed, including forms with a quasi-musical poetic diction in Urdu. Ghazals have a classical affinity with Sufism, and a number of major Sufi religious works are written in ghazal form. The relatively steady meter and the use of the refrain produce | (such as Homer's "rosy-fingered dawn" or "the wine-dark sea") or a longer refrain. Such repetition can add a somber tone to a poem, or can be laced with irony as the context of the words changes. Forms Specific poetic forms have been developed by many cultures. In more developed, closed or "received" poetic forms, the rhyming scheme, meter and other elements of a poem are based on sets of rules, ranging from the relatively loose rules that govern the construction of an elegy to the highly formalized structure of the ghazal or villanelle. Described below are some common forms of poetry widely used across a number of languages. Additional forms of poetry may be found in the discussions of the poetry of particular cultures or periods and in the glossary. Sonnet Among the most common forms of poetry, popular from the Late Middle Ages on, is the sonnet, which by the 13th century had become standardized as fourteen lines following a set rhyme scheme and logical structure. By the 14th century and the Italian Renaissance, the form had further crystallized under the pen of Petrarch, whose sonnets were translated in the 16th century by Sir Thomas Wyatt, who is credited with introducing the sonnet form into English literature. A traditional Italian or Petrarchan sonnet follows the rhyme scheme ABBA, ABBA, CDECDE, though some variation, perhaps the most common being CDCDCD, especially within the final six lines (or sestet), is common. The English (or Shakespearean) sonnet follows the rhyme scheme ABAB, CDCD, EFEF, GG, introducing a third quatrain (grouping of four lines), a final couplet, and a greater amount of variety with regard to rhyme than is usually found in its Italian predecessors. By convention, sonnets in English typically use iambic pentameter, while in the Romance languages, the hendecasyllable and Alexandrine are the most widely used meters. Sonnets of all types often make use of a volta, or "turn," a point in the poem at which an idea is turned on its head, a question is answered (or introduced), or the subject matter is further complicated. This volta can often take the form of a "but" statement contradicting or complicating the content of the earlier lines. In the Petrarchan sonnet, the turn tends to fall around the division between the first two quatrains and the sestet, while English sonnets usually place it at or near the beginning of the closing couplet. Sonnets are particularly associated with high poetic diction, vivid imagery, and romantic love, largely due to the influence of Petrarch as well as of early English practitioners such as Edmund Spenser (who gave his name to the Spenserian sonnet), Michael Drayton, and Shakespeare, whose sonnets are among the most famous in English poetry, with twenty being included in the Oxford Book of English Verse. However, the twists and turns associated with the volta allow for a logical flexibility applicable to many subjects. Poets from the earliest centuries of the sonnet to the present have utilized the form to address topics related to politics (John Milton, Percy Bysshe Shelley, Claude McKay), theology (John Donne, Gerard Manley Hopkins), war (Wilfred Owen, e.e. cummings), and gender and sexuality (Carol Ann Duffy). Further, postmodern authors such as Ted Berrigan and John Berryman have challenged the traditional definitions of the sonnet form, rendering entire sequences of "sonnets" that often lack rhyme, a clear logical progression, or even a consistent count of fourteen lines. Shi Shi () Is the main type of Classical Chinese poetry. Within this form of poetry the most important variations are "folk song" styled verse (yuefu), "old style" verse (gushi), "modern style" verse (jintishi). In all cases, rhyming is obligatory. The Yuefu is a folk ballad or a poem written in the folk ballad style, and the number of lines and the length of the lines could be irregular. For the other variations of shi poetry, generally either a four line (quatrain, or jueju) or else an eight-line poem is normal; either way with the even numbered lines rhyming. The line length is scanned by an according number of characters (according to the convention that one character equals one syllable), and are predominantly either five or seven characters long, with a caesura before the final three syllables. The lines are generally end-stopped, considered as a series of couplets, and exhibit verbal parallelism as a key poetic device. The "old style" verse (Gushi) is less formally strict than the jintishi, or regulated verse, which, despite the name "new style" verse actually had its theoretical basis laid as far back as Shen Yue (441–513 CE), although not considered to have reached its full development until the time of Chen Zi'ang (661–702 CE). A good example of a poet known for his Gushi poems is Li Bai (701–762 CE). Among its other rules, the jintishi rules regulate the tonal variations within a poem, including the use of set patterns of the four tones of Middle Chinese. The basic form of jintishi (sushi) has eight lines in four couplets, with parallelism between the lines in the second and third couplets. The couplets with parallel lines contain contrasting content but an identical grammatical relationship between words. Jintishi often have a rich poetic diction, full of allusion, and can have a wide range of subject, including history and politics. One of the masters of the form was Du Fu (712–770 CE), who wrote during the Tang Dynasty (8th century). Villanelle The villanelle is a nineteen-line poem made up of five triplets with a closing quatrain; the poem is characterized by having two refrains, initially used in the first and third lines of the first stanza, and then alternately used at the close of each subsequent stanza until the final quatrain, which is concluded by the two refrains. The remaining lines of the poem have an a-b alternating rhyme. The villanelle has been used regularly in the English language since the late 19th century by such poets as Dylan Thomas, W. H. Auden, and Elizabeth Bishop. Limerick A limerick is a poem that consists of five lines and is often humorous. Rhythm is very important in limericks for the first, second and fifth lines must have seven to ten syllables. However, the third and fourth lines only need five to seven. All of the lines must rhyme and have the same rhythm. Practitioners of the limerick included Edward Lear, Lord Alfred Tennyson, Rudyard Kipling, Robert Louis Stevenson. Tanka Tanka is a form of unrhymed Japanese poetry, with five sections totalling 31 on (phonological units identical to morae), structured in a 5-7-5-7-7 pattern. There is generally a shift in tone and subject matter between the upper 5-7-5 phrase and the lower 7-7 phrase. Tanka were written as early as the Asuka period by such poets as Kakinomoto no Hitomaro (fl. late 7th century), at a time when Japan was emerging from a period where much of its poetry followed Chinese form. Tanka was originally the shorter form of Japanese formal poetry (which was generally referred to as "waka"), and was used more heavily to explore personal rather than public themes. By the tenth century, tanka had become the dominant form of Japanese poetry, to the point where the originally general term waka ("Japanese poetry") came to be used exclusively for tanka. Tanka are still widely written today. Haiku Haiku is a popular form of unrhymed Japanese poetry, which evolved in the 17th century from the hokku, or opening verse of a renku. Generally written in a single vertical line, the haiku contains three sections totalling 17 on (morae), structured in a 5-7-5 pattern. Traditionally, haiku contain a kireji, or cutting word, usually placed at the end of one of the poem's three sections, and a kigo, or season-word. The most famous exponent of the haiku was Matsuo Bashō (1644–1694). An example of his writing: fuji no kaze ya oogi ni nosete Edo miyage the wind of Mt. Fuji I've brought on my fan! a gift from Edo Khlong The khlong (, ) is among the oldest Thai poetic forms. This is reflected in its requirements on the tone markings of certain syllables, which must be marked with mai ek (, , ) or mai tho (, , ). This was likely derived from when the Thai language had three tones (as opposed to today's five, a split which occurred during the Ayutthaya Kingdom period), two of which corresponded directly to the aforementioned marks. It is usually regarded as an advanced and sophisticated poetic form. In khlong, a stanza (bot, , ) has a number of lines (bat, , , from Pali and Sanskrit pāda), depending on the type. The bat are subdivided into two wak (, , from Sanskrit varga). The first wak has five syllables, the second has a variable number, also depending on the type, and may be optional. The type of khlong is named by the number of bat in a stanza; it may also be divided into two main types: khlong suphap (, ) and khlong dan (, ). The two differ in the number of syllables in the second wak of the final bat and inter-stanza rhyming rules. Khlong si suphap The khlong si suphap (, ) is the most common form still currently employed. It has four bat per stanza (si translates as four). The first wak of each bat has five syllables. The second wak has two or four syllables in the first and third bat, two syllables in the second, and four syllables in the fourth. Mai ek is required for seven syllables and Mai tho is required for four, as shown below. "Dead word" syllables are allowed in place of syllables which require mai ek, and changing the spelling of words to satisfy the criteria is usually acceptable. Ode Odes were first developed by poets writing in ancient Greek, such as Pindar, and Latin, such as Horace. Forms of odes appear in many of the cultures that were influenced by the Greeks and Latins. The ode generally has three parts: a strophe, an antistrophe, and an epode. The strophe and the antistrophe of the ode possess similar metrical structures and, depending on the tradition, similar rhyme structures. In contrast, the epode is written with a different scheme and structure. Odes have a formal poetic diction and generally deal with a serious subject. The strophe and antistrophe look at the subject from different, often conflicting, perspectives, with the epode moving to a higher level to either view or resolve the underlying issues.

Over time, differing forms for odes have developed with considerable variations in form and structure, but generally showing the original influence of the Pindaric or Horatian ode. One non-Western form which resembles the ode is the qasida in Persian poetry. Ghazal The (also , , , or ) is a form of poetry common in Arabic, Bengali, Persian and Urdu. In classic form, the has from five to fifteen rhyming couplets that share a refrain at the end of the second line. This refrain may be of one or several syllables and is preceded by a rhyme. Each line has an identical meter. The often reflects on a theme of unattainable love or divinity. As with other forms with a long history in many languages, many variations have been developed, including forms with a quasi-musical poetic diction in Urdu. Ghazals have a classical affinity with Sufism, and a number of major Sufi religious works are written in ghazal form. The relatively steady meter and the use of the refrain produce an incantatory effect, which complements Sufi mystical themes well. Among the masters of the form is Rumi, a 13th-century Persian poet. One of the most famous poet in this type of poetry is Hafez, whose poems often include the theme of exposing hypocrisy. His life and poems have been the subject of much analysis, commentary and interpretation, influencing post-fourteenth century Persian writing more than any other author. The West-östlicher Diwan of Johann Wolfgang von Goethe, a collection of lyrical poems, is inspired by the Persian poet Hafez. Genres In addition to specific forms of poems, poetry is often thought of in terms of different genres and subgenres. A poetic genre is generally a tradition or classification of poetry based on the subject matter, style, or other broader literary characteristics. Some commentators view genres as natural forms of literature. Others view the study of genres as the study of how different works relate and refer to other works. Narrative poetry Narrative poetry is a genre of poetry that tells a story. Broadly it subsumes epic poetry, but the term "narrative poetry" is often reserved for smaller works, generally with more appeal to human interest. Narrative poetry may be the oldest type of poetry. Many scholars of Homer have concluded that his Iliad and Odyssey were composed of compilations of shorter narrative poems that related individual episodes. Much narrative poetry—such as Scottish and English ballads, and Baltic and Slavic heroic poems—is performance poetry with roots in a preliterate oral tradition. It has been speculated that some features that distinguish poetry from prose, such as meter, alliteration and kennings, once served as memory aids for bards who recited traditional tales. Notable narrative poets have included Ovid, Dante, Juan Ruiz, William Langland, Chaucer, Fernando de Rojas, Luís de Camões, Shakespeare, Alexander Pope, Robert Burns, Adam Mickiewicz, Alexander Pushkin, Edgar Allan Poe, Alfred Tennyson, and Anne Carson. Lyric poetry Lyric poetry is a genre that, unlike epic and dramatic poetry, does not attempt to tell a story but instead is of a more personal nature. Poems in this |
this memoir lays down the axioms that positive and negative errors are equally probable, and that certain assignable limits define the range of all errors. Simpson also discusses continuous errors and describes a probability curve. The first two laws of error that were proposed both originated with Pierre-Simon Laplace. The first law was published in 1774, and stated that the frequency of an error could be expressed as an exponential function of the numerical magnitude of the error—disregarding sign. The second law of error was proposed in 1778 by Laplace, and stated that the frequency of the error is an exponential function of the square of the error. The second law of error is called the normal distribution or the Gauss law. "It is difficult historically to attribute that law to Gauss, who in spite of his well-known precocity had probably not made this discovery before he was two years old." Daniel Bernoulli (1778) introduced the principle of the maximum product of the probabilities of a system of concurrent errors. Adrien-Marie Legendre (1805) developed the method of least squares, and introduced it in his Nouvelles méthodes pour la détermination des orbites des comètes (New Methods for Determining the Orbits of Comets). In ignorance of Legendre's contribution, an Irish-American writer, Robert Adrain, editor of "The Analyst" (1808), first deduced the law of facility of error, where is a constant depending on precision of observation, and is a scale factor ensuring that the area under the curve equals 1. He gave two proofs, the second being essentially the same as John Herschel's (1850). Gauss gave the first proof that seems to have been known in Europe (the third after Adrain's) in 1809. Further proofs were given by Laplace (1810, 1812), Gauss (1823), James Ivory (1825, 1826), Hagen (1837), Friedrich Bessel (1838), W.F. Donkin (1844, 1856), and Morgan Crofton (1870). Other contributors were Ellis (1844), De Morgan (1864), Glaisher (1872), and Giovanni Schiaparelli (1875). Peters's (1856) formula for r, the probable error of a single observation, is well known. In the nineteenth century, authors on the general theory included Laplace, Sylvestre Lacroix (1816), Littrow (1833), Adolphe Quetelet (1853), Richard Dedekind (1860), Helmert (1872), Hermann Laurent (1873), Liagre, Didion and Karl Pearson. Augustus De Morgan and George Boole improved the exposition of the theory. In 1906, Andrey Markov introduced the notion of Markov chains, which played an important role in stochastic processes theory and its applications. The modern theory of probability based on the measure theory was developed by Andrey Kolmogorov in 1931. On the geometric side, contributors to The Educational Times were influential (Miller, Crofton, McColl, Wolstenholme, Watson, and Artemas Martin). See integral geometry for more info. Theory Like other theories, the theory of probability is a representation of its concepts in formal terms—that is, in terms that can be considered separately from their meaning. These formal terms are manipulated by the rules of mathematics and logic, and any results are interpreted or translated back into the problem domain. There have been at least two successful attempts to formalize probability, namely the Kolmogorov formulation and the Cox formulation. In Kolmogorov's formulation (see also probability space), sets are interpreted as events and probability as a measure on a class of sets. In Cox's theorem, probability is taken as a primitive (i.e., not further analyzed), and the emphasis is on constructing a consistent assignment of probability values to propositions. In both cases, the laws of probability are the same, except for technical details. There are other methods for quantifying uncertainty, such as the Dempster–Shafer theory or possibility theory, but those are essentially different and not compatible with the usually-understood laws of probability. Applications Probability theory is applied in everyday life in risk assessment and modeling. The insurance industry and markets use actuarial science to determine pricing and make trading decisions. Governments apply probabilistic methods in environmental regulation, entitlement analysis, and financial regulation. An example of the use of probability theory in equity trading is the effect of the perceived probability of any widespread Middle East conflict on oil prices, which have ripple effects in the economy as a whole. An assessment by a commodity trader that a war is more likely can send that commodity's prices up or down, and signals other traders of that opinion. Accordingly, the probabilities are neither assessed independently nor necessarily rationally. The theory of behavioral finance emerged to describe the effect of such groupthink on pricing, on policy, and on peace and conflict. In addition to financial assessment, probability can be used to analyze trends in biology (e.g., disease spread) as well as ecology (e.g., biological Punnett squares). As with finance, risk assessment can be used as a statistical tool to calculate the likelihood of undesirable events occurring, and can assist with implementing protocols to avoid encountering such circumstances. Probability is used to design games of chance so that casinos can make a guaranteed profit, yet provide payouts to players that are frequent enough to encourage continued play. Another significant application of probability theory in everyday life is reliability. Many consumer products, such as automobiles and consumer electronics, use reliability theory in product design to reduce the probability of failure. Failure probability may influence a manufacturer's decisions on a product's warranty. The cache language model and other statistical language models that are used in natural language processing are also examples of applications of probability theory. Mathematical treatment Consider an experiment that can produce a number of results. The collection of all possible results is called the sample space of the experiment, sometimes denoted as . The power set of the sample space is formed by considering all different collections of possible results. For example, rolling a die can produce six possible results. One collection of possible results gives an odd number on the die. Thus, the subset {1,3,5} is an element of the power set of the sample space of dice rolls. These collections are called "events". In this case, {1,3,5} is the event that the die falls on some odd number. If the results that actually occur fall in a given event, the event is said to have occurred. A probability is a way of assigning every event a value between zero and one, with the requirement that the event made up of all possible results (in our example, the event {1,2,3,4,5,6}) is assigned a value of one. To qualify as a probability, the assignment of values must satisfy the requirement that for any collection of mutually exclusive events (events with no common results, such as the events {1,6}, {3}, and {2,4}), the probability that at least one of the events will occur is given by the sum of the probabilities of all the individual events. The probability of an event A is written as , , or . This mathematical definition of probability can extend to infinite sample spaces, and even uncountable sample spaces, using the concept of a measure. The opposite or complement of an event A is the event [not A] (that is, the event of A not occurring), often denoted as , , or ; its probability is given by . As an example, the chance of not rolling a six on a six-sided die is . For a more comprehensive treatment, see Complementary event. If two events A and B occur on a single performance of an experiment, this is called the intersection or joint probability of A and B, denoted as . Independent events If two events, A and B are independent then the joint probability is For example, if two coins are flipped, then the chance of both being heads is . Mutually exclusive events If either event A or event B can occur but never both simultaneously, then they are called mutually exclusive events. If two events are mutually exclusive, then the probability of both occurring is denoted as and If two events are mutually exclusive, then the probability of either occurring is denoted as and For example, the chance of rolling a 1 or 2 on a six-sided is Not mutually exclusive events If the events are not mutually exclusive then For example, when drawing a card from a deck of cards, the chance of getting a heart or a face card (J,Q,K) (or both) is , since among the 52 cards of a deck, 13 are hearts, 12 are face cards, and 3 are both: here the possibilities included in the "3 that are both" are included in each of the "13 hearts" and the "12 face cards", but should only be counted once. Conditional probability Conditional probability is the probability of some event A, given the occurrence of some other event B. Conditional probability is written , and is read "the probability of A, given B". It is defined by If then is formally undefined by this expression. In this case and are independent, since . However, it is possible to define a conditional probability for some zero-probability events using a σ-algebra of such events (such as those arising from a continuous random variable). For | shows that there has been an interest in quantifying the ideas of probability for millennia, but exact mathematical descriptions arose much later. There are reasons for the slow development of the mathematics of probability. Whereas games of chance provided the impetus for the mathematical study of probability, fundamental issues are still obscured by the superstitions of gamblers. According to Richard Jeffrey, "Before the middle of the seventeenth century, the term 'probable' (Latin probabilis) meant approvable, and was applied in that sense, univocally, to opinion and to action. A probable action or opinion was one such as sensible people would undertake or hold, in the circumstances." However, in legal contexts especially, 'probable' could also apply to propositions for which there was good evidence. The sixteenth-century Italian polymath Gerolamo Cardano demonstrated the efficacy of defining odds as the ratio of favourable to unfavourable outcomes (which implies that the probability of an event is given by the ratio of favourable outcomes to the total number of possible outcomes). Aside from the elementary work by Cardano, the doctrine of probabilities dates to the correspondence of Pierre de Fermat and Blaise Pascal (1654). Christiaan Huygens (1657) gave the earliest known scientific treatment of the subject. Jakob Bernoulli's Ars Conjectandi (posthumous, 1713) and Abraham de Moivre's Doctrine of Chances (1718) treated the subject as a branch of mathematics. See Ian Hacking's The Emergence of Probability and James Franklin's The Science of Conjecture for histories of the early development of the very concept of mathematical probability. The theory of errors may be traced back to Roger Cotes's Opera Miscellanea (posthumous, 1722), but a memoir prepared by Thomas Simpson in 1755 (printed 1756) first applied the theory to the discussion of errors of observation. The reprint (1757) of this memoir lays down the axioms that positive and negative errors are equally probable, and that certain assignable limits define the range of all errors. Simpson also discusses continuous errors and describes a probability curve. The first two laws of error that were proposed both originated with Pierre-Simon Laplace. The first law was published in 1774, and stated that the frequency of an error could be expressed as an exponential function of the numerical magnitude of the error—disregarding sign.

their mother tongue. Poland's once multi-ethnic population communicated in numerous languages and lects which faded or disappeared along the course of history. There are currently 15 minority languages in Poland, including one recognized regional language, Kashubian, which is spoken by around 366,000 people in the northern regions of Kashubia and Pomerania. Languages having a minority status are Armenian, Belarusian, Czech, German, Yiddish, Hebrew, Lithuanian, Russian, Slovak and Ukrainian. Languages having the status of ethnic minority's language are Karaim, Lemko-Rusyn, Tatar and two Romani languages; Polska Roma and Bergitka Roma. Official recognition of a language provides certain rights under conditions prescribed by Polish law, including education and state financial support for promoting that language. Poland recognized secondary administrative languages or auxiliary languages in bilingual municipalities. Currently, German and Kashubian hold such status in 19 municipalities (gminas), Belarusian in 9 and Lithuanian in 1. Bilingual signs, names and advertisements are commonplace in those localities. Silesian and Wymysorys (Vilamovian) are not legally recognized or acknowledged as separate languages with a minority status. More than 50% of Polish citizens declare at least basic knowledge of the English language, followed by German (38%). Religion According to the 2015 census, 92.9% of all Polish citizens adhere to the Roman Catholic Church. An estimated 94.2% of the population are believers and 3.1% are irreligious, making Poland one of the more devout countries in Europe. Around 61.6% of all respondents outlined that religion is of high or very high importance. However, church attendance has decreased in recent years; only 38% of worshippers attended mass regularly on Sunday in 2018. Freedom of religion is guaranteed by the Polish Constitution, and the concordat guarantees the teaching of religion in state schools. For centuries the tribes inhabiting the lands of modern-day Poland have practised various forms of paganism known as Rodzimowierstwo, or "native faith". In the year 966, Duke Mieszko I converted to Christianity, and submitted to the authority of the Roman Catholic Church. This event came to be known as the Baptism of Poland. However, this did not put an end to pagan beliefs in the country. The persistence was demonstrated by a series of rebellions in the 1030s known as the pagan reaction, which also showed elements of a peasant uprising against medieval feudalism. Religious tolerance was an important part of Polish political culture, though it varied at times. In 1264, the Statute of Kalisz granted Jews unprecedented legal rights not found anywhere in Europe. In 1573, the Warsaw Confederation marked the formal beginning of extensive religious freedoms in Poland. It was partially influenced by the 1572 St. Bartholomew's Day Massacre in France, which prompted the nobility to prevent the monarch from carrying out reprehensible atrocities in Poland based on religious affiliation. The religious tolerance also spurred many theological movements such as the Calvinist Polish Brethren, a number of Protestant groups and atheists like Casimir Liszinski, one of the first atheist thinkers in Europe. Anabaptists fleeing 16th-century persecution in the Netherlands and Germany settled in Poland and became known as the Vistula delta Mennonites. From 16 October 1978 until his death on 2 April 2005, Cardinal Karol Józef Wojtyła was head of the Roman Catholic Church as Pope John Paul II. Contemporary religious minorities include Christian Orthodox (506,800), various Protestants (150,000) — including 77,500 Lutherans of the Evangelical-Augsburg Church, 23,000 Pentecostals in the Pentecostal Church in Poland, 10,000 Adventists in the Seventh-day Adventist Church and other smaller Evangelical denominations — Jehovah's Witnesses (126,827), Eastern Catholics, Mariavites, Jews, Muslims (Tatars) and neopagans, some of whom are members of the Native Polish Church. Famous sites of Roman Catholic pilgrimage in Poland include the Monastery of Jasna Góra in the city of Częstochowa, Basilica of Our Lady of Licheń, Kraków's Sanctuary of Divine Mercy and Święta Lipka (Holy Linden) in Masuria. Tourists also visit the family home of John Paul II in Wadowice outside Kraków. Christ the King in Świebodzin is the one of the tallest statues of Jesus in the world. Christian Orthodox pilgrims visit Mount Grabarka near Grabarka-Klasztor and the Hasidic Jews travel annually to the grave of a great rabbi in Leżajsk. Health Medical service providers and hospitals (szpitale) in Poland are subordinate to the Ministry of Health; it provides administrative oversight and scrutiny of general medical practice, and is obliged to maintain a high standard of hygiene and patient care. Poland has a universal healthcare system based on an all-inclusive insurance system; state subsidised healthcare is available to all citizens covered by the general health insurance program of the National Health Fund (NFZ). Private medical complexes exist nationwide; over 50% of the population uses both public and private sectors. Hospitals are organised according to the regional administrative structure, resultantly most towns, counties or municipalities possess their own provincial hospital or medical clinics. There are six types of hospital facilities, each with a particular area of medical expertise – I Grade Hospitals for general surgery, internal illnesses and obstetrics; II Grade Hospitals for child surgery, neurology, cardiology and ophthalmology; III Grade Hospitals including teaching hospitals for infectious diseases, nephrology, orthopedics, toxicology and transplantology; Oncology Hospitals for cancer treatment and brachytherapy; Pediatric Hospitals for child care; and Nationwide Hospitals for general and acute care. According to the Human Development Report from 2020, the average life expectancy at birth is 79 years (around 75 years for an infant male and 83 years for an infant female); the country has a low infant mortality rate (4 per 1,000 births). In 2019, the principal cause of death was ischemic heart disease; diseases of the circulatory system accounted for 45% of all deaths. In the same year, Poland was also the 15th-largest importer of medications and pharmaceutical products. Education The Jagiellonian University founded in 1364 by Casimir III in Kraków was the first institution of higher learning established in Poland, and is one of the oldest universities still in continuous operation. Poland's Commission of National Education (Komisja Edukacji Narodowej), established in 1773, was the world's first state ministry of education. The framework for primary and secondary schooling in contemporary Poland is established by the Ministry of National Education. Kindergarten attendance is optional for children aged between three and five, with one year being compulsory for six-year-olds. Primary education traditionally begins at the age of seven, although children aged six can attend at the request of their parents or guardians. Elementary school spans eight grades, at the end of which an obligatory three-part exam on Polish, mathematics and a foreign language is to be undertaken. Secondary schooling is dependent on student preference – either a four-year high school (liceum), a five-year technical school (technikum) or various vocational studies (szkoła branżowa) can be pursued by each individual pupil. A liceum or technikum is concluded with a maturity exit exam (matura), which must be passed in order to apply for a university or other institutions of higher learning. The standards of higher tertiary education are imposed by the Ministry of Science and Higher Education. In Poland, there are over 500 university-level institutions, with technical, medical, economic, agricultural, pedagogical, theological, musical, maritime and military faculties. The University of Warsaw and Warsaw Polytechnic, the University of Wrocław, Adam Mickiewicz University in Poznań and the University of Technology in Gdańsk are among the most prominent. There are three conventional academic degrees in Poland – licencjat or inżynier (first cycle qualification), magister (second cycle qualification) and doktor (third cycle qualification). In 2018, the Programme for International Student Assessment, coordinated by the Organisation for Economic Co-operation and Development, ranked Poland's educational system higher than the OECD average; the study showed that students in Poland perform better academically than in most OECD countries. Culture The culture of Poland is closely connected with its intricate 1,000-year history and forms an important constituent in western civilization. The Poles take great pride in their national identity which is often associated with the colours white and red, and exuded by the expression biało-czerwoni ("whitereds"). National symbols, chiefly the crowned white-tailed eagle, are often visible on clothing, insignia and emblems. The appreciation of Poland's traditions and cultural heritage is commonly known as Polonophilia. With origins in the customs of the tribal Lechites, over time the culture of Poland has been influenced by its connection to Western culture and trends, as well as developing its own unique traditions such as Sarmatism. The people of Poland have traditionally been seen as hospitable to artists from abroad and eager to follow cultural and artistic trends popular in foreign countries, for instance, the 16th- and 17th-century tradition of coffin portraits (portret trumienny) was only observed in Poland and Roman Egypt. In the 19th and 20th centuries the Polish focus on cultural advancement often took precedence over political and economic activity. These factors have contributed to the versatile nature of Polish art. The architectural monuments of great importance are protected by the National Heritage Board of Poland. Over 100 of the country's most significant tangible wonders were enlisted onto the Historic Monuments Register, with further 17 being recognized by UNESCO as World Heritage Sites. Poland is renowned for its brick Gothic castles, granaries and churches as well as diversely-styled tenements, market squares and town halls. The majority of Polish cities founded on Magdeburg Law in the Middle Ages evolved around central marketplaces, a distinguishable urban characteristic which can be observed to this day. Medieval and Renaissance cloth halls were once an abundant feature of many towns. Holidays and traditions There are 13 government-approved annual public holidays – New Year on 1 January, Three Kings' Day on 6 January, Easter Sunday and Easter Monday, Labour Day on 1 May, Constitution Day on 3 May, Pentecost, Corpus Christi, Feast of the Assumption on 15 August, All Saints' Day on 1 November, Independence Day on 11 November and Christmastide on 25 and 26 December. Particular traditions and superstitious customs observed in Poland are not found elsewhere in Europe. Though Christmas Eve (Wigilia) is not a public holiday, it remains the most memorable day of the entire year. Trees are decorated on 24 December, hay is placed under the tablecloth to resemble Jesus' manger, Christmas wafers (opłatek) are shared between gathered guests and a twelve-dish meatless supper is served that same evening when the first star appears. An empty plate and seat are symbolically left at the table for an unexpected guest. On occasion, carolers journey around smaller towns with a folk Turoń creature until the Lent period. A widely-popular doughnut and sweet pastry feast occurs on Fat Thursday, usually 52 days prior to Easter. Eggs for Holy Sunday are painted and placed in decorated baskets that are previously blessed by clergymen in churches on Easter Saturday. Easter Monday is celebrated with pagan dyngus festivities, where the youth is engaged in water fights. Cemeteries and graves of the deceased are annually visited by family members on All Saints' Day; tombstones are cleaned as a sign of respect and candles are lit to honour the dead on an unprecedented scale. Music Artists from Poland, including famous musicians such as Chopin, Rubinstein, Paderewski, Penderecki and Wieniawski, and traditional, regionalized folk composers create a lively and diverse music scene, which even recognizes its own music genres, such as sung poetry and disco polo. The origins of Polish music can be traced to the 13th century; manuscripts have been found in Stary Sącz containing polyphonic compositions related to the Parisian Notre Dame School. Other early compositions, such as the melody of Bogurodzica and God Is Born (a coronation polonaise tune for Polish kings by an unknown composer), may also date back to this period, however, the first known notable composer, Nicholas of Radom, lived in the 15th century. Diomedes Cato, a native-born Italian who lived in Kraków, became a renowned lutenist at the court of Sigismund III; he not only imported some of the musical styles from southern Europe but blended them with native folk music. In the 17th and 18th centuries, Polish baroque composers wrote liturgical music and secular compositions such as concertos and sonatas for voices or instruments. At the end of the 18th century, Polish classical music evolved into national forms like the polonaise. Wojciech Bogusławski is accredited with composing the first Polish national opera, titled Krakowiacy i Górale, which premiered in 1794. Traditional Polish folk music has had a major effect on the works of many Polish composers, and no more so than on Fryderyk Chopin, a widely recognised national hero of the arts. All of Chopin's works involve the piano and are technically demanding, emphasising nuance and expressive depth. As a great composer, Chopin invented the musical form known as the instrumental ballade and made major innovations to the piano sonata, mazurka, waltz, nocturne, polonaise, étude, impromptu and prélude, he was also the composer of a number of polonaises which borrowed heavily from traditional Polish folk music. It is largely thanks to him that such pieces gained great popularity throughout Europe during the 19th century. Several Polish composers such as Szymanowski drew inspiration from Chopin's folk-influenced style. Nowadays the most distinctive folk music can be heard in the towns and villages of the mountainous south, particularly in the region surrounding the winter resort town of Zakopane. Poland today has an active music scene, with the jazz and metal genres being particularly popular among the contemporary populace. Polish jazz musicians such as Krzysztof Komeda created a unique style, which was most famous in the 1960s and 1970s and continues to be popular to this day. Poland has also become a major venue for large-scale music festivals, chief among which are the Open'er Festival, Opole Festival and Sopot Festival. Art Art in Poland has always reflected European trends while maintaining its unique character. The Kraków Academy of Fine Arts, later developed by Jan Matejko, produced monumental portrayals of customs and significant events in Polish history. Other institutions such as the Academy of Fine Arts in Warsaw were more innovative and focused on both historical and contemporary styles. Notable art academies include the Kraków School of Art and Fashion Design, Art Academy of Szczecin, University of Fine Arts in Poznań and the Geppert Academy of Fine Arts in Wrocław. Perhaps the most prominent and internationally admired Polish artist was Tamara de Lempicka, who specialized in the style of Art Deco. Lempicka was described as "the first woman artist to become a glamour star." Another notable was Caziel, born Zielenkiewicz, who represented Cubism and Abstraction in France and England. Prior to the 19th century only Daniel Schultz and Italian-born Marcello Bacciarelli had the privilege of being recognized abroad. The Young Poland movement witnessed the birth of modern Polish art, and engaged in a great deal of formal experimentation led by Jacek Malczewski, Stanisław Wyspiański, Józef Mehoffer, and a group of Polish Impressionists. Stanisław Witkiewicz was an ardent supporter of Realism, its main representative being Józef Chełmoński, while Artur Grottger specialized in Romanticism. Within historically orientated circles, Henryk Siemiradzki dominated with his monumental Academic Art and ancient Roman theme. Since the inter-war years, Polish art and documentary photography has enjoyed worldwide fame and in the 1960s the Polish School of Posters was formed. Throughout the entire country, many national museum and art institutions hold valuable works by famous masters. Major museums in Poland include the National Museum in Warsaw, Poznań, Wrocław, Kraków, and Gdańsk, as well as the Museum of John Paul II Collection, and the Wilanów Museum. Important collections are also held at the Royal Castle in Warsaw, Wawel Castle and in the Palace on the Isle. Contemporary art galleries include Zachęta, Ujazdów, and MOCAK. The most distinguished painting of Poland is Lady with an Ermine by Leonardo da Vinci, held at the Czartoryski Museum in Kraków. Although not Polish, the work had a strong influence on Polish culture and has been often associated with Polish identity. Architecture Polish cities and towns reflect a whole spectrum of European architectural styles. Romanesque architecture is represented by St. Andrew's Church, Kraków, and St. Mary's Church, Gdańsk, is characteristic for the Brick Gothic style found in Poland. Richly decorated attics and arcade loggias are the common elements of the Polish Renaissance architecture, as evident in the City Hall in Poznań. For some time the late renaissance style known as mannerism, most notably in the Bishop's Palace in Kielce, coexisted with the early baroque style, typified in the Church of Saints Peter and Paul in Kraków. History has not been kind to Poland's architectural monuments. Nonetheless, a number of ancient structures have survived: castles, churches, and stately homes, often unique in the regional or European context. Some of them have been painstakingly restored, like Wawel Castle, or completely reconstructed, including the Old Town and Royal Castle of Warsaw and the Old Town of Gdańsk. The architecture of Gdańsk is mostly of the Hanseatic variety, a Gothic style common among the former trading cities along the Baltic Sea and in the northern part of Central Europe. The architectural style of Wrocław is mainly representative of German architecture since it was for centuries located within the Holy Roman Empire. The centres of Kazimierz Dolny and Sandomierz on the Vistula are good examples of well-preserved medieval towns. Poland's ancient capital, Kraków, ranks among the best-preserved Gothic and Renaissance urban complexes in Europe. The second half of the 17th century is marked by baroque architecture. Side towers, such as those of Branicki Palace in Białystok, are typical for the Polish baroque. The classical Silesian baroque is represented by the University in Wrocław. The profuse decorations of the Branicki Palace in Warsaw are characteristic of the rococo style. The centre of Polish classicism was Warsaw under the rule of the last Polish king Stanisław II Augustus. The Palace on the Isle is a chief example of Polish neoclassical architecture. Lublin Castle represents the Gothic Revival style in architecture, while the Izrael Poznański Palace in Łódź is an example of eclecticism. Traditional folk architecture in the villages and small towns scattered across the vast Polish countryside was characterized by its extensive use of wood and red brick as primary building materials, common for Central Europe. Some of the best preserved and oldest structures include ancient stone temples in Silesia and fortified wooden churches across southeastern Poland in the Beskids and Bieszczady regions of the Carpathian mountains. Numerous examples of secular structures such as Polish manor houses (dworek), farmhouses (chata), granaries, mills, barns and country inns (karczma) can still be found in some Polish regions. However, traditional construction methods faded in the early-mid 20th century, when Poland's population experienced a demographic shift to urban dwelling away from the countryside. Literature The earliest examples of Polish literature date to the 12th century, when Poland's official language was Latin, and early published works were predominantly written by foreigners. Gallus Anonymus, a monk of disputed origin, was the first chronicler who meticulously described Poland's culture, language and territories in Gesta principum Polonorum (c. 1112–1118). Latin remained the principal tool of literary expression in Poland until the 18th century, when it was replaced in favour of Polish and French. Historically, Polish literature concentrated extensively around the themes of true drama and poetic-expressive romanticism than on fiction. Patriotism, spirituality and aphorisms were paramount and political or social allegories were common moral narratives. The first documented phrase in the Polish language reads "Day ut ia pobrusa, a ti poziwai" ("Let me grind, and you take a rest"), reflecting the use of quern-stone in early Poland. The phrase was recorded by an abbot in the Latin-based Liber fundationis from 1269 to 1273, which outlined the history of a Cistercian monastery in the Silesian village of Henryków. The sentence has been included in the UNESCO Memory of World Register. The oldest extant manuscript of fine prose in Old Polish is the Holy Cross Sermons, and the earliest religious text is the Bible of Queen Sophia. One of the first printing houses was established by Kasper Straube in the 1470s, while Jan Haller was considered the pioneer of commercial print in Poland. Haller's Calendarium cracoviense, an astronomical wall calendar from 1474, is Poland's oldest surviving print. The tradition of extending Polish historiography in Latin was subsequently inherited by Vincent Kadłubek, Bishop of Kraków in the 13th century, and Jan Długosz in the 15th century. This practice, however, was abandoned by Jan Kochanowski, who became one of the first Polish Renaissance authors to write most of his works in Polish, along with Nicholas Rey. Other writers of the Polish Renaissance include Johannes Dantiscus, Andreus Fricius Modrevius, Matthias Sarbievius, Piotr Skarga and Klemens "Ianicius" Janicki, who was laureled by the Pope. The leading figure of the Polish Reformation was theologian and writer John Laski, who, with the permission of King Edward VI of England, created the European Protestant Congregation of London in 1550. During the Baroque era, the Jesuits greatly influenced Polish literature and literary techniques, often relying on God and religious matters. The leading baroque poet was Jan Andrzej Morsztyn, who incorporated Marinism into his publications. Jan Chryzostom Pasek, also a respected baroque writer, is mostly remembered for his tales and memoirs reflecting sarmatian culture in the Polish–Lithuanian Commonwealth. Subsequently, the Polish Enlightenment was headed by Samuel Linde, Hugo Kołłątaj, Izabela Czartoryska and Julian Ursyn Niemcewicz. In 1776, Ignacy Krasicki composed the first milestone novel titled The Adventures of Mr. Nicholas Wisdom. Among the best known Polish Romantics are the "Three Bards" – the three national poets active in the age of foreign partitions – Adam Mickiewicz, Juliusz Słowacki and Zygmunt Krasiński. The narrative poem Pan Tadeusz by Mickiewicz is Poland's national epic and a compulsory reading (lektura) in the country's schools. Joseph Conrad, the son of dramatist Apollo Korzeniowski, came to fame with his English-language novels and stories that are informed with elements of the Polish national experience. Conrad's Heart of Darkness, Nostromo and Lord Jim are believed to be one of the finest works ever written, placing him among the greatest novelists of all time. Modern Polish literature is versatile, with its fantasy genre having been particularly praised. The philosophical sci-fi novel Solaris is an acclaimed example of Stanisław Lem's literary legacy, whereas The Witcher, a fantasy series by Andrzej Sapkowski, is a much-celebrated work of contemporary Polish fiction. In the 20th century, five Polish authors were awarded the Nobel Prize in Literature – Henryk Sienkiewicz for Quo Vadis, Władysław Reymont for The Peasants, Isaac Bashevis Singer, Czesław Miłosz and Wisława Szymborska. In 2019, Polish author Olga Tokarczuk was awarded the Nobel Prize in Literature for the year 2018. Cuisine Polish cuisine has evolved over the centuries to become highly eclectic due to Poland's history. Polish cuisine shares many similarities with other Central European cuisines, especially German and Austrian as well as Jewish, French, Italian and Turkish culinary traditions. Polish-styled cooking in other cultures is often referred to as cuisine à la polonaise. Polish dishes are usually rich in meat, especially pork, chicken and beef (depending on the region), winter vegetables (sauerkraut cabbage in bigos), and spices. It is also characteristic in its use of various kinds of noodles, the most notable of which are kluski, as well as cereals such as kasha (from the Polish word kasza) and a variety of breads like the world-renowned bagel. Polish cuisine is hearty and uses a lot of cream and eggs. Festive meals such as the meatless Christmas Eve dinner (Wigilia) or Easter breakfast could take days to prepare in their entirety. The main course usually includes a serving of meat, such as roast, chicken, or kotlet schabowy (breaded pork cutlet), vegetables, side dishes and salads, including surówka – shredded root vegetables with lemon and sugar (carrot, celeriac, seared beetroot) or sauerkraut (, ). The side dishes are usually potatoes, rice or cereal. Meals conclude with a dessert such as sernik (cheesecake), makowiec (poppy seed pastry), or napoleonka (cream pie). The Polish national dishes are bigos ; pierogi ; kielbasa; kotlet schabowy breaded cutlet; gołąbki cabbage rolls; zrazy roulade; pieczeń roast ; sour cucumber soup (zupa ogórkowa, ); mushroom soup, (zupa grzybowa, quite different from the North American cream of mushroom); zupa pomidorowa tomato soup ; rosół variety of meat broth; żurek sour rye soup; flaki tripe soup; barszcz and chłodnik among others. Traditional alcoholic beverages include honey mead, widespread since the 13th century, beer, wine and vodka (old Polish names include okowita and gorzała). The world's first written mention of vodka originates from Poland. The most popular alcoholic drinks at present are beer and wine which took over from vodka more popular in the years 1980–1998. Tea remains common in Polish society since the 19th century, whilst coffee is drunk widely since the 18th century. Other frequently consumed beverages include various mineral waters and juices, soft drinks popularized by the fast-food chains since the late 20th century, as well as buttermilk, soured milk and kefir. Fashion and design The particular clothing styles in Poland evolved with each century. In the 1600s high-class noblemen and magnates developed a strong sympathy for Orientalism, which was also common in other parts of Europe and became known as Sarmatism. The attire mediated between Western and Ottoman styles and outfits included a żupan, delia, kontusz, pas, decorative karabela swords and less often turbans brought by foreign merchants. The period of Polish Sarmatism eventually faded in the wake of the 18th century. The Polish national dress as well as the fashion and etiquette of Poland also reached the royal court at Versailles in the 1700s. French dresses inspired by Polish attire were called à la polonaise, meaning "Polish-styled". The most famous example is the robe à la polonaise, a woman's garment with draped and swagged overskirt, worn over an underskirt or petticoat. Another notable example is the Witzchoura, a long mantle with collar and hood, which was possibly introduced by Napoleon's Polish mistress Maria Walewska. The scope of influence also entailed furniture; rococo Polish beds with canopies became commonplace in French palaces during the 18th century. Several Polish designers and stylists left a lifelong legacy of beauty inventions and cosmetics, most notable being Maksymilian Faktorowicz and Helena Rubinstein. Faktorowicz created a line of cosmetics company in California known as Max Factor and coined the term "make-up" based on the verb phrase "to make up" one's face, now widely used as an alternative for describing cosmetics. Faktorowicz also raised to fame by inventing modern eyelash extensions and by providing services to Hollywood artists. As of 2020, Poland possesses the fifth-largest cosmetic market in Europe. Founded in 1983, Inglot Cosmetics is the country's largest beauty products manufacturer and retailer active in 700 locations worldwide, including retail salons in New York City, London, Milan, Dubai and Las Vegas. Established in 1999, the retail store Reserved is Poland's most successful clothing store chain, operating over 1,700 retail shops in 19 countries. Internationally successful models from Poland include Anja Rubik, Joanna Krupa, Jac Jagaciak, Kasia Struss, Małgosia Bela, and Magdalena Frąckowiak. Cinema The history of Polish cinema is as long as the history of cinematography itself. Over the decades, Poland has produced outstanding directors, film producers, cartoonists and actors that achieved world fame, especially in Hollywood. Moreover, Polish inventors played an important role in the development of world cinematography and modern-day television. Among the most famous directors and producers, who worked in Poland as well as | sovereignty and allow democratic elections to take place. However, upon achieving victory in 1945, the elections organized by the occupying Soviet authorities were falsified and were used to provide a veneer of legitimacy for Soviet hegemony over Polish affairs. The Soviet Union instituted a new communist government in Poland, analogous to much of the rest of the Eastern Bloc. As elsewhere in Communist Europe, the Soviet influence over Poland was met with armed resistance from the outset which continued into the 1950s. Despite widespread objections, the new Polish government accepted the Soviet annexation of the pre-war eastern regions of Poland (in particular the cities of Wilno and Lwów) and agreed to the permanent garrisoning of Red Army units on Poland's territory. Military alignment within the Warsaw Pact throughout the Cold War came about as a direct result of this change in Poland's political culture. In the European scene, it came to characterize the full-fledged integration of Poland into the brotherhood of communist nations. The new communist government took control with the adoption of the Small Constitution on 19 February 1947. The Polish People's Republic (Polska Rzeczpospolita Ludowa) was officially proclaimed in 1952. In 1956, after the death of Bolesław Bierut, the régime of Władysław Gomułka became temporarily more liberal, freeing many people from prison and expanding some personal freedoms. Collectivization in the Polish People's Republic failed. A similar situation repeated itself in the 1970s under Edward Gierek, but most of the time persecution of anti-communist opposition groups persisted. Despite this, Poland was at the time considered to be one of the least oppressive states of the Eastern Bloc. Labour turmoil in 1980 led to the formation of the independent trade union "Solidarity" ("Solidarność"), which over time became a political force. Despite persecution and imposition of martial law in 1981, it eroded the dominance of the Polish United Workers' Party and by 1989 had triumphed in Poland's first partially free and democratic parliamentary elections since the end of the Second World War. Lech Wałęsa, a Solidarity candidate, eventually won the presidency in 1990. The Solidarity movement heralded the collapse of communist regimes and parties across Europe. 1990s to present A shock therapy program, initiated by Leszek Balcerowicz in the early 1990s, enabled the country to transform its socialist-style planned economy into a market economy. As with other post-communist countries, Poland suffered temporary declines in social and economic standards, but it became the first post-communist country to reach its pre-1989 GDP levels, which is achieved by 1995 thanks largely to its booming economy. Most visibly, there were numerous improvements in human rights, such as freedom of speech, internet freedom (no censorship), civil liberties (1st class) and political rights (1st class), as ranked by Freedom House non-governmental organization. In 1991, Poland became a member of the Visegrád Group and joined the North Atlantic Treaty Organization (NATO) alliance in 1999 along with the Czech Republic and Hungary. Poles then voted to join the European Union in a referendum in June 2003, with Poland becoming a full member on 1 May 2004. Poland joined the Schengen Area in 2007, as a result of which, the country's borders with other member states of the European Union have been dismantled, allowing for full freedom of movement within most of the EU. On 10 April 2010, the President of the Republic of Poland, Lech Kaczyński, along with 89 other high-ranking Polish officials died in a plane crash near Smolensk, Russia. The president's party was on their way to attend an annual service of commemoration for the victims of the Katyń massacre when the tragedy took place. In 2011, the ruling Civic Platform won parliamentary elections. Poland joined the European Space Agency in 2012, as well as organised the UEFA Euro 2012 (along with Ukraine). In 2013, Poland also became a member of the Development Assistance Committee. In 2014, the Prime Minister of Poland, Donald Tusk, was chosen to be President of the European Council, and resigned as prime minister. The 2015 and 2019 elections were won by the conservative Law and Justice Party (PiS), resulting in increased friction between Poland and the EU. In December 2017, Mateusz Morawiecki was sworn in as the new Prime Minister, succeeding Beata Szydlo, in office since 2015. They both represented ruling Law and Justice party, led by party chairman Jarosław Kaczyński. President Andrzej Duda, supported by Law and Justice party, was narrowly re-elected in the 2020 presidential election. Geography Poland covers an area of approximately , of which 98.52% is dry land and 1.48% is water. Extending across several geographical regions, the country is the 9th-largest by area in Europe and 69th largest in the world. Topographically, Poland is diverse and has access to the sea, the mountains and open terrain. Although most of the central parts of the country are flat, there is an abundance of lakes, rivers, hills, swamps, beaches, islands and forests elsewhere. In the north-west is the Baltic seacoast spanning from the Bay of Pomerania to the Gulf of Gdańsk. The coast is marked by several spits, coastal lakes (former bays that have been cut off from the sea), and dunes. The largely straight coastline is indented by the Szczecin Lagoon, the Bay of Puck, and the Vistula Lagoon. The central and northern parts of the country lie within the North European Plain. Rising above these lowlands is a geographical region comprising four hilly districts of moraines and moraine-dammed lakes formed during and after the Pleistocene ice age, notably the Pomeranian Lake District, the Greater Polish Lake District, the Kashubian Lake District, and the Masurian Lake District. The Masurian Lake District is the largest of the four and covers much of north-eastern Poland. The lake districts form a series of moraine belts along the southern shore of the Baltic Sea. South of the Northern European Plain are the regions of Lusatia, Silesia and Masovia, which are marked by broad ice-age river valleys. The extreme south of Poland is mountainous; it runs from the Sudetes in the west to the Carpathian Mountains in the east. The highest part of the Carpathian massif is the Tatra Mountain range, along Poland's southern border. Geology The geological structure of Poland has been shaped by the continental collision of Europe and Africa over the past 60 million years and, more recently, by the Quaternary glaciations of northern Europe. Both processes shaped the Sudetes and the Carpathian Mountains. The moraine landscape of northern Poland contains soils made up mostly of sand or loam, while the ice age river valleys of the south often contain loess. The Polish Jura, the Pieniny, and the Western Tatras consist of limestone, whereas the High Tatras, the Beskids, and the Karkonosze mountain ranges are made up mainly of granite and basalts. The Polish Jura Chain has some of the oldest rock formations on the continent of Europe. Poland has over 70 mountains over in elevation, all situated in the Tatras. Poland's highest point is the north-western summit of Mount Rysy at in elevation. At its foot lie the mountain lakes of Czarny Staw (Black Lake) and Morskie Oko (Eye of the Sea), both naturally-made tarns. Other notable uplands include the Pieniny and Holy Cross Mountains, the Table Mountains noted for their unusual rock formations, the Bieszczady in the far southeast of the country in which the highest peak is Tarnica at , and the Gorce Mountains whose highest point is Turbacz at . The highest point of the Sudeten massif is Mount Śnieżka (), shared with the Czech Republic. The lowest point in Poland – at below sea level – is at Raczki Elbląskie, near Elbląg in the Vistula Delta. In the Zagłębie Dąbrowskie (the Coal Fields of Dąbrowa) region in the Silesian Voivodeship in southern Poland is an area of sparsely vegetated sand known as the Błędów Desert. It covers an area of . It is not a natural desert and was formed by human activity from the Middle Ages onwards. The Baltic Sea activity in Słowiński National Park created sand dunes which in the course of time separated the bay from the sea creating two lakes. As waves and wind carry sand inland the dunes slowly move, at a rate of per year. Some dunes reach the height of up to . The highest peak of the park is Rowokol at above sea level. Waters The longest rivers are the Vistula (), long; the Oder () which forms part of Poland's western border, long; its tributary, the Warta, long; and the Bug, a tributary of the Vistula, long. The Vistula and the Oder flow into the Baltic Sea, as do numerous smaller rivers in Pomerania. Poland's lengthy waterways have been used since early times for navigation; the Vikings ventured up the Polish rivers in their longships. In the Middle Ages and in early modern times, the shipment of tangible goods down the Vistula toward Gdańsk and onward to other parts of Europe took on great importance. With almost ten thousand closed bodies of water covering more than each, Poland has one of the highest numbers of lakes in the world. In Europe, only Finland has a greater density of lakes. The largest lakes, covering more than , are Lake Śniardwy and Lake Mamry in Masuria as well as Lake Łebsko and Lake Drawsko in Pomerania. The lake with the greatest depth—of more than —is Lake Hańcza in the Wigry Lake District, east of Masuria in Podlaskie Voivodeship. The Polish Baltic coast is approximately long and extends from Świnoujście on the islands of Usedom and Wolin in the west to Krynica Morska on the Vistula Spit in the east. For the most part, Poland has a smooth coastline, which has been shaped by the continual movement of sand by currents and winds. This continual erosion and deposition has formed cliffs, dunes, and spits, many of which have migrated landwards to close off former lagoons, such as Łebsko Lake in the Słowiński National Park. The largest spits are Hel Peninsula and the Vistula Spit. The coast line is varied also by Szczecin and Vistula Lagoons and several lakes, including Jamno. The largest Polish Baltic island is Wolin, located within Wolin National Park. The largest sea harbours are Szczecin, Świnoujście, Gdańsk, Gdynia, Police and Kołobrzeg and the main coastal resorts – Świnoujście, Międzydzdroje, Kołobrzeg, Łeba, Sopot, Władysławowo and the Hel Peninsula. In the valley of Pilica river in Tomaszów Mazowiecki there is a unique natural karst spring of water containing calcium salts, that is an object of protection at Blue Springs Nature Reserve in the Sulejów Landscape Park. The red waves are absorbed by water, hence only blue and green are reflected from the bottom of the spring, giving the water atypical colour. Land use Forests cover about 29.6% of Poland's land area based on international standards. Its overall percentage is still increasing. Forests of Poland are managed by the national program of reforestation (KPZL), aiming at an increase of forest-cover to 33% in 2050. The largest forest complex in Poland is Lower Silesian Wilderness. More than 1% of Poland's territory, , is protected within 23 Polish national parks. Three more national parks are projected for Masuria, the Polish Jura, and the eastern Beskids. In addition, wetlands along lakes and rivers in central Poland are legally protected, as are coastal areas in the north. There are 123 areas designated as landscape parks, along with numerous nature reserves and other protected areas under the Natura 2000 network. In 2017, approximately of land was occupied by farms and farmsteads, over half of Poland's total area. Biodiversity Phytogeographically, Poland belongs to the Central European province of the Circumboreal Region within the Boreal Kingdom. According to the World Wide Fund for Nature, the territory of Poland belongs to three Palearctic Ecoregions of the continental forest spanning Central and Northern European temperate broadleaf and mixed forest ecoregions, as well as the Carpathian montane conifer forest. The most common deciduous trees found across the country are oak, maple, and beech; the most common conifers are pine, spruce, and fir. An estimated 68.7% of all forests are coniferous. Poland has historically been home to rare species of animals, as well as the two largest European mammals: the wisent (żubr) and aurochs (tur). The last aurochs of Europe became extinct in 1627 in the Polish Jaktorów Forest, while the wisent survived until the 20th century only at Białowieża. It has been since reintroduced to other countries. Other wild species include the brown bear in Białowieża, in the Tatras, and in the Beskids; the gray wolf and the Eurasian lynx in various forests; the moose in northern Poland; and the beaver in Masuria, Pomerania, and Podlaskie. Game animals such as red deer, roe deer, and wild boar are found in most woodlands. Eastern Poland abounds in ancient woods, like the Białowieża Forest, that have not been disturbed by human or industrial activity. There are also large forested areas in the mountains, Greater Poland, Pomerania, Lubusz Land, and Lower Silesia. The Lubusz Voivodeship is currently the most arboraceous province in the country; 52% of its territory is occupied by forests. Poland is also a significant breeding ground for a variety of European migratory birds. One quarter of the global population of white storks (40,000 breeding pairs) live in Poland, particularly in the lake districts and the wetlands along the Biebrza, the Narew, and the Warta, which are part of nature reserves or national parks. Climate The climate is mostly temperate throughout the country. The climate is oceanic in the north-west and becomes gradually warmer and continental towards the south-east. Summers are generally warm, with average temperatures between depending on the region. Winters are rather cold, with average temperatures around in the northwest and in the northeast. Precipitation falls throughout the year, although, especially in the east, winter is drier than summer. The warmest region in Poland is Lower Silesia (Lower Silesian Voivodeship) in the southwest of the country, where temperatures in the summer average between but can go as high as on some days in the warmest months of July and August. The warmest cities in Poland are Tarnów in Lesser Poland, and Wrocław in Lower Silesia. The average temperatures in Wrocław are in the summer and in the winter, but Tarnów has the longest summer in all of Poland, which lasts for 115 days, from mid-May to mid-September. The coldest region of Poland is in the northeast, around the area of Suwałki within the Podlaskie Voivodeship, where the climate is affected by cold fronts coming from Scandinavia and Siberia. The average temperature in the winter in Podlaskie ranges from . The biggest impact of the oceanic climate is observed in Świnoujście and Baltic Sea seashore area from Police to Słupsk. Government and politics Poland is a representative democracy, with a president as the head of state. The government structure centers on the Council of Ministers, led by a prime minister. The president appoints the cabinet according to the proposals of the prime minister, typically from the majority coalition in the Sejm. The president is elected by popular vote every five years. The current president is Andrzej Duda and the prime minister is Mateusz Morawiecki. Polish voters elect a bicameral parliament consisting of a 460-member lower house (Sejm) and a 100-member Senate (Senat). The Sejm is elected under proportional representation according to the d'Hondt method, a method similar to that used in many parliamentary political systems. The Senat, on the other hand, is elected under the first-past-the-post voting method, with one senator being returned from each of the 100 constituencies. With the exception of ethnic minority parties, only candidates of political parties receiving at least 5% of the total national vote can enter the Sejm. When sitting in a joint session, members of the Sejm and Senat form the National Assembly (the Zgromadzenie Narodowe). The National Assembly is formed on three occasions: when a new president takes the oath of office; when an indictment against the President of the Republic is brought to the State Tribunal (Trybunał Stanu); and when a president's permanent incapacity to exercise his duties due to the state of his health is declared. To date, only the first instance has occurred. The judicial branch plays an important role in decision-making. Its major institutions include the Supreme Court (Sąd Najwyższy); the Supreme Administrative Court (Naczelny Sąd Administracyjny); the Constitutional Tribunal (Trybunał Konstytucyjny); and the State Tribunal (Trybunał Stanu). On the approval of the Senat, the Sejm also appoints the ombudsman or the Commissioner for Civil Rights Protection (Rzecznik Praw Obywatelskich) for a five-year term. The ombudsman has the duty of guarding the observance and implementation of the rights and liberties of Polish citizens and residents, of the law and of principles of community life and social justice. Law The Constitution of Poland is the enacted supreme law, and the Polish legal system is based on the principle of civil rights, governed by the code of civil law. The current democratic constitution was adopted by the National Assembly of Poland on 2 April 1997; it guarantees a multi-party state with freedoms of religion, speech and assembly, prohibits the practices of forced medical experimentation, torture or corporal punishment, and acknowledges the inviolability of the home, the right to form trade unions, and the right to strike. The judiciary incorporates a four-tier court system composed of the Supreme Court, the Supreme Administrative Court, Common Courts (District, Regional, Appellate) and the Military Court. Judges are nominated by the National Council of the Judiciary and are appointed for life by the president. The Constitutional and State Tribunals are separate judicial bodies, which rule the constitutional liability of people holding the highest offices of state and supervise the compliance of statutory law, thus protecting the Constitution. Historically, the most significant Polish legal act is the Constitution of 3 May 1791, the first modern constitution in Europe. Instituted as a Government Act, it was designed to redress long-standing political defects of the federative Polish–Lithuanian Commonwealth and its Golden Liberty. Previously, only the Henrician Articles (1573) signed by each of Poland's elected monarchs could perform the function of a set of basic laws. The new Constitution introduced political equality between townspeople and the nobility (szlachta), and placed the peasants under the protection of the government. It abolished pernicious parliamentary policies such as the liberum veto, which permitted any deputy to rescind all the legislation passed in the interest of a foreign power. The 3 May Constitution sought to supplant the existing anarchy fostered by some of the country's reactionary magnates, with a more egalitarian and democratic constitutional monarchy. The Constitution influenced many later democratic movements across the globe. Tax-paying women were allowed to take part in Polish political life until the third partition in 1795. In 1918 the Second Polish Republic became one of the first countries to introduce universal women's suffrage. Poland has a low homicide rate at 0.7 murders per 100,000 people, as of 2018. Rape, assault and violent crime remain at a very low level, although not all cases are recorded by the authorities. Abortion is permitted only in cases of rape, incest or when the woman's life is in danger. Congenital disorder and stillbirth are not covered by the law, forcing some women to seek abortion abroad, and others to seek the assistance of psychiatrists willing to testify on the negative psychological impact of stillbirth. Poland does not criminalize homosexuality, and its legality was confirmed in 1932. The Polish Constitution defines marriage as a union between a man and a woman. Foreign relations Poland is the fifth most populous member state of the European Union and has a grand total of 52 representatives in the European Parliament as of 2020. Since joining the union in 2004, successive Polish governments have pursued policies to extend the country's role in European and international affairs. Poland is an emerging regional power in Central Europe. The capital of Warsaw serves as the headquarters for Frontex, the European Union's agency for external border security as well as ODIHR, one of the principal institutions of the Organization for Security and Cooperation in Europe. Apart from the European Union, Poland has been a member of NATO since 1999, the UN, the World Trade Organization, the Organisation for Economic Co-operation and Development (OECD) since 1996, European Economic Area, International Energy Agency, Council of Europe, Organization for Security and Co-operation in Europe, International Atomic Energy Agency, European Space Agency, G6, Council of the Baltic Sea States, Visegrád Group, Weimar Triangle, Schengen Agreement, Lublin Triangle and Bucharest Nine. Over the past two decades, Poland significantly strengthened its ties with the United States, thus becoming one of its closest allies in Europe. Poland was part of the US-led coalition force during the Iraq War in 2003, and sent its troops in the first phase of the conflict, jointly with the United Kingdom and Australia. Along with NATO, Poland maintains military presence in the Middle East, the Baltic states and in the Balkans. Historically, Poland has had particularly friendly relations with Hungary; this special relationship was recognized by the parliaments of both countries in 2007 with the joint declaration of March 23 as "The Day of Polish-Hungarian Friendship". Military The Polish Armed Forces are composed of five branches – Land Forces (Wojska Lądowe), Navy (Marynarka Wojenna), Air Force (Siły Powietrzne), Special Forces (Wojska Specjalne) and the Territorial Defence Force (Wojska Obrony Terytorialnej). The military is subordinate to the Ministry of National Defence of the Republic of Poland. However, its commander-in-chief in peacetime is the President of the Republic, who nominates officers, the Minister for National Defence and the chief of staff. Polish military tradition is generally commemorated by the Armed Forces Day, celebrated annually on 15 August. As of 2018, the Polish Armed Forces have a combined strength of 144,142 soldiers. The Polish Navy primarily operates on the Baltic Sea and conducts operations such as maritime patrol, search and rescue for the section of the Baltic under Polish sovereignty, as well as hydrographic measurements and research. The Polish Air Force routinely takes part in Baltic Air Policing assignments. In 2003, the F-16C Block 52 was selected as the new general multi-role fighter for the air force. In January 2020, Poland has approved the delivery for F-35 Lightning II combat aircraft. Poland is currently spending 2% of its GDP on defence (approximately US$13.5 billion in 2020), which is expected to grow to 2.5% by 2030. According to SIPRI, the country exported EUR€487 million worth of arms and armaments to other countries, primarily to the United States, Chile, France and South Africa. The mission of the armed forces is the defence of Poland's territorial integrity and Polish interests abroad. The country's national security goal is to further integrate with NATO and European defence, economic, and political institutions. Compulsory military service for men was discontinued in 2008. From 2007, until conscription ended in 2008, the mandatory service was nine months. Polish military doctrine reflects the same defensive nature as that of its NATO partners and the country actively hosts NATO's military exercises. From 1953 to 2009 Poland was a large contributor to various United Nations peacekeeping missions. The Polish Armed Forces took part in the 2003 invasion of Iraq, deploying 2,500 soldiers in the south of that country and commanding the 17-nation multinational force in Iraq. Poland also maintains troops in the Middle East, the Baltic states and in the Balkans; 1,650 soldiers were deployed in 2019. Law enforcement and emergency services Law enforcement in Poland is performed by several agencies which are subordinate to the Ministry of Interior and Administration – the State Police (Policja), assigned to investigate crimes or transgression; the Municipal City Guard, which maintains public order; and several specialized agencies, such as the Polish Border Guard. Private security firms are also common, although they possess no legal authority to arrest or detain a suspect. Municipal guards are primarily headed by provincial, regional or city councils; individual guards are not permitted to carry firearms unless instructed by their superior commanding officer or commandant. The Internal Security Agency (ABW, or ISA in English) is the chief counter-intelligence instrument safeguarding Poland's internal security, along with Agencja Wywiadu (AW) which identifies threats and collects secret information abroad. The Central Investigation Bureau of Police (CBŚP) and the Central Anticorruption Bureau (CBA) are responsible for countering organized crime and corruption in state and private institutions. Emergency services in Poland consist of the emergency medical services, search and rescue units of the Polish Armed Forces and State Fire Service. Emergency medical services in Poland are operated by local and regional governments, but are a part of the centralized national agency - the National Medical Emergency Service (Państwowe Ratownictwo Medyczne). All emergency services personnel are uniformed and security services can be easily recognized during regular patrols in both large urban areas or smaller suburban localities. Administrative divisions Poland's current voivodeships (provinces) are largely based on the country's historic regions, whereas those of the past two decades (to 1998) had been centred on and named for individual cities. The new units range in area from less than for Opole Voivodeship to more than for Masovian Voivodeship. Administrative authority at the voivodeship level is shared between a government-appointed voivode (governor), an elected regional assembly (sejmik) and a voivodeship marshal, an executive elected by that assembly. The voivodeships are subdivided into powiats (often referred to in English as counties), and these are further divided into gminas (also known as communes or municipalities). Major cities normally have the status of both gmina and powiat. Poland has 16 voivodeships, 380 powiats (including 66 cities with powiat status), and 2,478 gminas. Economy Poland's economy and Gross Domestic Product (GDP) is currently the sixth largest in the European Union by nominal standards, and the fifth largest by purchasing power parity. It is also one of the fastest growing within the Union. Around 61% of the employed population belongs to the tertiary service sector, 31% to industry and manufacturing, and the remaining 8% to the agricultural sector. Although Poland is a member of EU's single market, the country has not adopted the Euro as legal tender and maintains its own currency – the Polish złoty (zł, PLN). Poland is the regional economic leader in Central Europe, with nearly 40 per cent of the 500 biggest companies in the region (by revenues) as well as a high globalisation rate. The country's largest firms compose the WIG20 and WIG30 indexes, which is traded on the Warsaw Stock Exchange. According to reports made by the National Bank of Poland, the value of Polish foreign direct investments reached almost 300 billion PLN at the end of 2014. The Central Statistical Office estimated that in 2014 there were 1,437 Polish corporations with interests in 3,194 foreign entities. Having a strong domestic market, low private debt, low unemployment rate, flexible currency, and not being dependent on a single export sector, Poland is the only European economy to have avoided the recession of 2008. The country is the 20th largest exporter of goods and services in the world and its most successful exports include machinery, furniture, food products, clothing, shoes, cosmetics and video games. Exports of goods and services are valued at approximately 56% of GDP, as of 2020. Poland's largest trading partners include Germany, Czech Republic, United Kingdom, France and Italy. In September 2018, the unemployment rate was estimated at 5.7%, one of the lowest in the European Union. In 2019, Poland passed a law that would exempt workers under the age of 26 from income tax. The Polish banking sector is the largest in the region, with 32.3 branches per 100,000 adults. The banks are the largest and most developed sector of the country's financial markets. They are regulated by the Polish Financial Supervision Authority. Poland's banking sector has approximately 5 national banks, a network of nearly 600 cooperative banks and 18 branches of foreign-owned banks. In addition, foreign investors have controlling stakes in nearly 40 commercial banks, which make up 68% of the banking capital. Products and goods manufactured in Poland include: electronics, buses and trams (Solaris, Solbus), helicopters and planes (PZL Świdnik, PZL Mielec), trains (Pesa, Newag), ships (Gdańsk Shipyard, Szczecin Shipyard), military equipment (FB "Łucznik" Radom, Bumar-Łabędy, Jelcz), medicines (Polpharma, Polfa), food (Tymbark, Hortex, E. Wedel), clothes (LLP), glass, pottery (Bolesławiec), chemical products and others. Well-known brands and companies include Alior Bank, Orlen&Lotos Group, Inglot Cosmetics, Plus, Play, Brainly, Netguru, GOG.com, CD Projekt, Trefl and Allegro. Poland is also one of the world's biggest producers of copper, silver, coal, furniture, automotive parts and soft drink. Tourism Poland experienced a significant increase in the number of tourists after joining the European Union in 2004. With nearly 21 million international arrivals in 2019, tourism contributes considerably to the overall economy and makes up a relatively large proportion of the country's service market. Tourist attractions in Poland vary, from the mountains in the south to the sandy beaches in the north, with a trail of nearly every architectural style. The most visited city is Kraków, which was the former capital of Poland and serves as a relic of the Polish Golden Age and the Renaissance. Kraków also held royal coronations of most Polish kings and monarchs at Wawel, the nation's chief historical landmark. Among other notable sites in the country is Wrocław, one of the oldest cities in Poland which was a model for the founding of Kraków. Wrocław is famous for its dwarf statues, a large market square with two town halls, and the oldest Zoological Gardens with one of the world's largest number of animal species. The Polish capital Warsaw and its historical Old Town were entirely reconstructed after wartime destruction. Other cities attracting countless tourists include Gdańsk, Poznań, Lublin, Toruń as well as the site of the German Auschwitz concentration camp in Oświęcim. A notable highlight is the 13th-century Wieliczka Salt Mine with its labyrinthine tunnels, a subterranean lake and chapels carved by miners out of rock salt beneath the ground. Poland's main tourist offerings include outdoor activities such as skiing, sailing, mountain hiking and climbing, as well as agritourism, sightseeing historical monuments. Tourist destinations include the Baltic Sea coast in the north; the Masurian Lake District and Białowieża Forest in the east; on the south Karkonosze, the Table Mountains and the Tatra Mountains, where Rysy – the highest peak of Poland, and Eagle's Path mountain trail are located. The Pieniny and Bieszczady Mountains lie in the extreme south-east. There are over 100 castles in the country, most in the Lower Silesian Voivodeship, and also on the Trail of the Eagles' Nests. The largest castle in the world by land area is situated in Malbork, in north-central Poland. Energy The electricity generation sector in Poland is largely fossil-fuel–based. Many power plants nationwide use Poland's position as a major European exporter of coal to their advantage by continuing to use coal as the primary raw material in the production of their energy. In 2013, Poland scored 48 out of 129 states in the Energy Sustainability Index. The three largest Polish coal mining firms (Węglokoks, Kompania Węglowa and JSW) extract around 100 million tonnes of coal annually. Renewable forms of energy account for a smaller proportion of Poland's full energy generation capacity. However, the national government has set targets for the development of renewable energy sources in Poland (the share of energy from renewable sources in the gross final energy consumption in 2019 was – 12,18%). Increasing the share of energy from renewable sources and a significant reduction in CO2 emissions to be achieved with the help of biofuels, photovoltaics, construction of wind farms on the land and the Baltic Sea, hydroelectric stations and nuclear power plant. Poland has around 164,800,000,000 m3 of proven natural gas reserves and around 96,380,000 barrels of proven oil reserves. These reserves are exploited by energy supply companies such as PKN Orlen ("the only Polish company listed in the Fortune Global 500"), PGNiG. However, the small amounts of fossil fuels naturally occurring in Poland are insufficient to satisfy the full energy consumption needs of the population and industry. Consequently, the country is a net importer of oil and natural gas. Therefore, since the second decade of the 21st century, Poland has been strongly developing the so-called North Gate in which the most important components are the Baltic Pipe, the Świnoujście LNG terminal and Floating Storage and Regasification Unit in Port of Gdańsk. The five largest companies supplying Poland electricity are PGE, Tauron, Enea, Energa and Innogy Poland. Transport Transport in Poland is provided by means of rail, road, marine shipping and air travel. The country is part of EU's Schengen Area and is an important transport hub along neighbouring Germany due to its strategic position in Central Europe. Some of the longest European routes, including the E40, run through Poland. The country has a good network of highways, composed of express roads and motorways. At the start of 2020, Poland had of highways in use. In addition, all local and regional roads are monitored by the National Road Rebuilding Programme, which aims to improve the quality of travel in the countryside and suburban localities. In 2017, the nation had of railway track, the third longest in Europe after Germany and France. The Polish State Railways (PKP) is the dominant railway operator in the country. In December 2014, Poland began to implement high–speed rail routes connecting major Polish cities, and started passenger service using the New Pendolino train, operating at 200 km/h on the Central Rail Line (CMK).

neither can exist without the other. Choreography is the art of making dances, and the person who practices this art is called a choreographer. Music Music is an art form which combines pitch, rhythm, and dynamic to create sound. It can be performed using a variety of instruments and styles and is divided into genres such as folk, jazz, hip hop, pop, and rock, etc. As an art form, music can occur in live or recorded formats, and can be planned or improvised. As music is a protean art, it easily coordinates with words for songs as physical movements do in dance. Moreover, it has a capability of shaping human behaviors as it impacts our emotions. History Western performing arts Starting in the 6th century BC, the Classical period of performing art began in Greece, ushered in by the tragic poets such as Sophocles. These poets wrote plays which, in some cases, incorporated dance (see Euripides). The Hellenistic period began the widespread use of comedy. However, by the 6th century AD, Western performing arts had been largely ended, as the Dark Ages began. Between the 9th century and 14th century, performing art in the West was limited to religious historical enactments and morality plays, organized by the Church in celebration of holy days and other important events. Renaissance In the 15th century performing arts, along with the arts in general, saw a revival as the Renaissance began in Italy and spread throughout Europe plays, some of which incorporated dance, which were performed and Domenico da Piacenza credited with the first use of the term ballo (in De Arte Saltandi et Choreas Ducendi) instead of danza (dance) for his baletti or balli. The term eventually became Ballet. The first Ballet per se is thought to be Balthasar de Beaujoyeulx's Ballet Comique de la Reine (1581). By the mid-16th century Commedia Dell'arte became popular in Europe, introducing the use of improvisation. This period also introduced the Elizabethan masque, featuring music, dance and elaborate costumes as well as professional theatrical companies in England. William Shakespeare's plays in the late 16th century developed from this new class of professional performance. In 1597, the first opera, Dafne was performed and throughout the 17th century, opera would rapidly become the entertainment of choice for the aristocracy in most of Europe, and eventually for large numbers of people living in cities and towns throughout Europe. Modern era The introduction of the proscenium arch in Italy during the 17th century established the traditional theatre form that persists to this day. Meanwhile, in England, the Puritans forbade acting, bringing a halt to performing arts that lasted until 1660. After that, women began to appear in both French and English plays. The French introduced a formal dance instruction in the late 17th century. It is also during this time that the first plays were performed in the American Colonies. During the 18th century, the introduction of the popular opera buffa brought opera to the masses as an accessible form of performance. Mozart's The Marriage of Figaro and Don Giovanni are landmarks of the late 18th century opera. At the turn of the 19th century, Beethoven and the Romantic movement ushered in a new era that led first to the spectacles of grand opera and then to the musical dramas of Giuseppe Verdi and the Gesamtkunstwerk (total work of art) of the operas of Richard Wagner leading directly to the music of the 20th century. The 19th century was a period of growth for the performing arts for all social classes, technical advances such as the introduction of gaslight to theatres, burlesque, minstrel dancing, and variety theatre. In ballet, women make great progress in the previously male-dominated art. Modern dance began in the late 19th century and early 20th century in response to the restrictions of traditional ballet. The arrival of Sergei Diaghilev's Ballets Russes (1909–1929) revolutionized ballet and the performing arts generally throughout the Western world, most importantly through Diaghilev's emphasis on collaboration, which brought choreographers, dancers, set designers/artists, composers and musicians together to revitalize and revolutionize ballet. It is extremely complex. Konstantin Stanislavski's "System" revolutionized acting in the early 20th century, and continues to have a major influence on actors of stage and screen to the current day. Both impressionism and modern realism were introduced to the stage during this period. With the invention of the motion picture in the late 19th century by Thomas Edison and the growth of the motion picture industry in Hollywood in the early 20th century, film became a dominant performance medium throughout the 20th and 21st centuries. Rhythm and blues, a cultural phenomenon of black America, rose to prominence in the early 20th century; influencing a range of later popular music styles internationally. In the 1930s Jean Rosenthal introduced what would become modern stage lighting, changing the nature of the stage as the Broadway musical became a phenomenon in the United States. Postwar Post-World War II performing arts were highlighted by the resurgence of both ballet and opera in the Western world. Postmodernism in performing arts dominated the 1960s to large extent. Eastern performing arts Middle East The earliest recorded theatrical event dates back to 2000 BC with the passion plays of Ancient Egypt. The story of the god Osiris was performed annually at festivals throughout the civilization, marking the known beginning of a long relationship between theatre and religion. The most popular forms of theater in the medieval Islamic world were puppet theatre (which included hand puppets, shadow plays and marionette productions) and live passion plays known as ta'ziya, where actors re-enact episodes from Muslim history. In particular, Shia Islamic plays revolved around the shaheed (martyrdom) of Ali's sons Hasan ibn Ali and Husayn ibn Ali. Live secular plays were known as akhraja, recorded in medieval adab literature, though they were less common than puppetry and ta'ziya theater. Iran In Iran there are other forms of theatrical events such as Naghali or Naqqāli (story telling), ٰRu-Howzi, Siah-Bazi, Parde-Khani, and Mareke giri. Prior to the twentieth century, storytelling was the most recognized form of entertainment, although today, some forms still remain. One form, Naghali, was traditionally performed in coffeehouses where the storytellers, or Naghals (Naqqāls), only recited sections of a story at a time, thus retaining regular cliental. These stories were based on events of historical or religious importance and many referenced poetry from the Shahnameh. Oftentimes these stories were altered to bond with the atmosphere or mood of the audience. India Folk theatre and dramatics can be traced to the religious ritualism of the Vedic peoples in the 2nd millennium BC. This folk theatre of the misty past was mixed with dance, food, ritualism, plus a depiction of events from daily life. The last element made it the origin of the classical theatre of later times. Many historians, notably D. D. Kosambi, Debiprasad Chattopadhyaya, Adya Rangacharaya, etc. have referred to the prevalence of ritualism amongst Indo-Aryan tribes in which some members of the tribe acted as if they were wild animals and some others were the hunters. Those who acted as mammals like goats, buffaloes, reindeer, monkeys, etc. were chased by those playing the role of hunters. Bharata Muni (fl. 5th–2nd century BC) was an ancient Indian writer best known for writing the Natya Shastra of Bharata, a theoretical treatise on Indian performing arts, including theatre, dance, acting, and music, which has been compared to Aristotle's Poetics. Bharata is often known as the father of Indian theatrical arts. His Natya Shastra seems to be the first attempt to develop the technique or rather art, of drama in a systematic manner. The Natya Shastra tells us not only what is to be portrayed in a drama, but how the portrayal is to be done. Drama, as Bharata Muni says, is the imitation of men and their doings (loka-vritti). As men and their doings have to be respected on the stage, so drama in Sanskrit is also known by | and object manipulation, and other kinds of performances are present in all human cultures. The history of music and dance date to pre-historic times whereas circus skills date to at least Ancient Egypt. Many performing arts are performed professionally. Performance can be in purpose built buildings, such as theatres and opera houses, on open air stages at festivals, on stages in tents such as circuses and on the street. Live performances before an audience are a form of entertainment. The development of audio and video recording has allowed for private consumption of the performing arts. The performing arts often aims to express one's emotions and feelings. Performers Artists who participate in performing arts in front of an audience are called performers. Examples of these include actors, comedians, dancers, magicians, circus artists, musicians, and singers. Performing arts are also supported by workers in related fields, such as songwriting, choreography and stagecraft. A performer who excels in acting, singing, and dancing is commonly referred to as a triple threat. Well-known examples of historical triple threat include Selena Gomez, Gene Kelly, Fred Astaire, Judy Garland, Sammy Davis Jr., Michael Jackson, Justin Timberlake, Beyoncé, Christina Aguilera, Madonna, Ariana Grande, Jennifer Lopez and Zendaya. Performers often adapt their appearance, such as with costumes and stage makeup, stage lighting, and sound. Types Performing arts may include dance, music, opera, theatre and musical theatre, magic, illusion, mime, spoken word, puppetry, circus arts, professional wrestling and performance art. There is also a specialized form of fine art, in which the artists perform their work live to an audience. This is called performance art. Most performance art also involves some form of plastic art, perhaps in the creation of props. Dance was often referred to as a plastic art during the Modern dance era. Theatre Theatre is the branch of performing arts concerned with acting out stories in front of an audience, using a combination of speech, gesture, music, dance, sound, and spectacle. Any one or more of these elements is considered performing arts. In addition to the standard narrative dialogue style of plays, theater takes such forms as plays, musicals, opera, ballet, illusion, mime, classical Indian dance, kabuki, mummers' plays, improvisational theatre, comedy, pantomime, and non-conventional or contemporary forms like postmodern theatre, postdramatic theatre, or performance art. Dance In the context of performing arts, dance generally refers to human movement, typically rhythmic and to music, used as a form of audience entertainment in a performance setting. Definitions of what constitutes dance are dependent on social, cultural, aesthetic, artistic, and moral constraints and range from functional movement (such as folk dance) to codified, virtuoso techniques such as ballet. There is one another modern form of dance that emerged in 19th- 20th century with the name of Free dance style. This form of dance was structured to create a harmonious personality which included features such as physical and spiritual freedom. Isadora Duncan was the first female dancer who argued about "woman of future" and developed novel vector of choreography using Nietzsche's idea of "supreme mind in free mind". Dance is a powerful impulse, but the art of dance is that impulse channeled by skillful performers into something that becomes intensely expressive and that may delight spectators who feel no wish to dance themselves. These two concepts of the art of dance—dance as a powerful impulse and dance as a skillfully choreographed art practiced largely by a professional few—are the two most important connecting ideas running through any consideration of the subject. In dance, the connection between the two concepts is stronger than in some other arts, and neither can exist without the other. Choreography is the art of making dances, and the person who practices this art is called a choreographer. Music Music is an art form which combines pitch, rhythm, and dynamic to create sound. It can be performed using a variety of instruments and styles and is divided into genres such as folk, jazz, hip hop, pop, and rock, etc. As an art form, music can occur in live or recorded formats, and can be planned or improvised. As music is a protean art, it easily coordinates with words for songs as physical movements do in dance. Moreover, it has a capability of shaping human behaviors as it impacts our emotions. History Western performing arts Starting in the 6th century BC, the Classical period of performing art began in Greece, ushered in by the tragic poets such as Sophocles. These poets wrote plays which, in some cases, incorporated dance (see Euripides). The Hellenistic period began the widespread use of comedy. However, by the 6th century AD, Western performing arts had been largely ended, as the Dark Ages began. Between the 9th century and 14th century, performing art in the West was limited to religious historical enactments and morality plays, organized by the Church in celebration of holy days and other important events. Renaissance In the 15th century performing arts, along with the arts in general, saw a revival as the Renaissance began in Italy and spread throughout Europe plays, some of which incorporated dance, which were performed and Domenico da Piacenza credited with the first use of the term ballo (in De Arte Saltandi et Choreas Ducendi) instead of danza (dance) for his baletti or balli. The term eventually became Ballet. The first Ballet per se is thought to be Balthasar de Beaujoyeulx's Ballet Comique de la Reine (1581). By the mid-16th century Commedia Dell'arte became popular in Europe, introducing the use of improvisation. This period also introduced the Elizabethan masque, featuring music, dance and elaborate costumes as well as professional theatrical companies in England. William Shakespeare's plays in the late 16th century developed from this new class of professional performance. In 1597, the first opera, Dafne was performed and throughout the 17th century, opera would rapidly become the entertainment of choice for the aristocracy in most of Europe, and eventually for large numbers of people living in cities and towns throughout Europe. Modern era The introduction of the proscenium arch in Italy during the 17th century established the traditional theatre form that persists to this day. Meanwhile, in England, the Puritans forbade acting, bringing a halt to performing arts that lasted until 1660. After that, women began to appear in both French and English plays. The French introduced a formal dance instruction in the late 17th century. It is also during this time that the first plays were performed in the American Colonies. During the 18th century, the introduction of the popular opera buffa brought opera to the masses as an accessible form of performance. Mozart's The Marriage of Figaro and Don Giovanni are landmarks of the late 18th century opera. At the turn of the 19th century, Beethoven and the Romantic movement ushered in a new era that led first to the spectacles of grand opera and then to the musical dramas of Giuseppe Verdi and the Gesamtkunstwerk (total work of art) of the operas of Richard Wagner leading directly to the music of the 20th century. The 19th century was a period of growth for the performing arts for all social classes, technical advances such as the introduction of gaslight to theatres, burlesque, minstrel dancing, and variety theatre. In ballet, women make great progress in the previously male-dominated art. Modern dance began in the late 19th century and early 20th century in response to the restrictions of traditional ballet. The arrival of Sergei Diaghilev's Ballets Russes (1909–1929) revolutionized ballet and the performing arts generally throughout the Western world, most importantly through Diaghilev's emphasis on collaboration, which brought choreographers, dancers, set designers/artists, composers and musicians together to revitalize and revolutionize ballet. It is extremely complex. Konstantin Stanislavski's "System" revolutionized acting in the early |
Wave Particle Difference While physics aims to discover universal laws, its theories lie in explicit domains of applicability. Loosely speaking, the laws of classical physics accurately describe systems whose important length scales are greater than the atomic scale and whose motions are much slower than the speed of light. Outside of this domain, observations do not match predictions provided by classical mechanics. Einstein contributed the framework of special relativity, which replaced notions of absolute time and space with spacetime and allowed an accurate description of systems whose components have speeds approaching the speed of light. Planck, Schrödinger, and others introduced quantum mechanics, a probabilistic notion of particles and interactions that allowed an accurate description of atomic and subatomic scales. Later, quantum field theory unified quantum mechanics and special relativity. General relativity allowed for a dynamical, curved spacetime, with which highly massive systems and the large-scale structure of the universe can be well-described. General relativity has not yet been unified with the other fundamental descriptions; several candidate theories of quantum gravity are being developed. Relation to other fields Prerequisites Mathematics provides a compact and exact language used to describe the order in nature. This was noted and advocated by Pythagoras, Plato, Galileo, and Newton. Physics uses mathematics to organise and formulate experimental results. From those results, precise or estimated solutions are obtained, or quantitative results, from which new predictions can be made and experimentally confirmed or negated. The results from physics experiments are numerical data, with their units of measure and estimates of the errors in the measurements. Technologies based on mathematics, like computation have made computational physics an active area of research. Ontology is a prerequisite for physics, but not for mathematics. It means physics is ultimately concerned with descriptions of the real world, while mathematics is concerned with abstract patterns, even beyond the real world. Thus physics statements are synthetic, while mathematical statements are analytic. Mathematics contains hypotheses, while physics contains theories. Mathematics statements have to be only logically true, while predictions of physics statements must match observed and experimental data. The distinction is clear-cut, but not always obvious. For example, mathematical physics is the application of mathematics in physics. Its methods are mathematical, but its subject is physical. The problems in this field start with a "mathematical model of a physical situation" (system) and a "mathematical description of a physical law" that will be applied to that system. Every mathematical statement used for solving has a hard-to-find physical meaning. The final mathematical solution has an easier-to-find meaning, because it is what the solver is looking for. Pure physics is a branch of fundamental science (also called basic science). Physics is also called "the fundamental science" because all branches of natural science like chemistry, astronomy, geology, and biology are constrained by laws of physics. Similarly, chemistry is often called the central science because of its role in linking the physical sciences. For example, chemistry studies properties, structures, and reactions of matter (chemistry's focus on the molecular and atomic scale distinguishes it from physics). Structures are formed because particles exert electrical forces on each other, properties include physical characteristics of given substances, and reactions are bound by laws of physics, like conservation of energy, mass, and charge. Physics is applied in industries like engineering and medicine. Application and influence Applied physics is a general term for physics research, which is intended for a particular use. An applied physics curriculum usually contains a few classes in an applied discipline, like geology or electrical engineering. It usually differs from engineering in that an applied physicist may not be designing something in particular, but rather is using physics or conducting physics research with the aim of developing new technologies or solving a problem. The approach is similar to that of applied mathematics. Applied physicists use physics in scientific research. For instance, people working on accelerator physics might seek to build better particle detectors for research in theoretical physics. Physics is used heavily in engineering. For example, statics, a subfield of mechanics, is used in the building of bridges and other static structures. The understanding and use of acoustics results in sound control and better concert halls; similarly, the use of optics creates better optical devices. An understanding of physics makes for more realistic flight simulators, video games, and movies, and is often critical in forensic investigations. With the standard consensus that the laws of physics are universal and do not change with time, physics can be used to study things that would ordinarily be mired in uncertainty. For example, in the study of the origin of the earth, one can reasonably model earth's mass, temperature, and rate of rotation, as a function of time allowing one to extrapolate forward or backward in time and so predict future or prior events. It also allows for simulations in engineering that drastically speed up the development of a new technology. But there is also considerable interdisciplinarity, so many other important fields are influenced by physics (e.g., the fields of econophysics and sociophysics). Research Scientific method Physicists use the scientific method to test the validity of a physical theory. By using a methodical approach to compare the implications of a theory with the conclusions drawn from its related experiments and observations, physicists are better able to test the validity of a theory in a logical, unbiased, and repeatable way. To that end, experiments are performed and observations are made in order to determine the validity or invalidity of the theory. A scientific law is a concise verbal or mathematical statement of a relation that expresses a fundamental principle of some theory, such as Newton's law of universal gravitation. Theory and experiment Theorists seek to develop mathematical models that both agree with existing experiments and successfully predict future experimental results, while experimentalists devise and perform experiments to test theoretical predictions and explore new phenomena. Although theory and experiment are developed separately, they strongly affect and depend upon each other. Progress in physics frequently comes about when experimental results defy explanation by existing theories, prompting intense focus on applicable modelling, and when new theories generate experimentally testable predictions, which inspire the development of new experiments (and often related equipment). Physicists who work at the interplay of theory and experiment are called phenomenologists, who study complex phenomena observed in experiment and work to relate them to a fundamental theory. Theoretical physics has historically taken inspiration from philosophy; electromagnetism was unified this way. Beyond the known universe, the field of theoretical physics also deals with hypothetical issues, such as parallel universes, a multiverse, and higher dimensions. Theorists invoke these ideas in hopes of solving particular problems with existing theories; they then explore the consequences of these ideas and work toward making testable predictions. Experimental physics expands, and is expanded by, engineering and technology. Experimental physicists who are involved in basic research, design and perform experiments with equipment such as particle accelerators and lasers, whereas those involved in applied research often work in industry, developing technologies such as magnetic resonance imaging (MRI) and transistors. Feynman has noted that experimentalists may seek areas that have not been explored well by theorists. Scope and aims Physics covers a wide range of phenomena, from elementary particles (such as quarks, neutrinos, and electrons) to the largest superclusters of galaxies. Included in these phenomena are the most basic objects composing all other things. Therefore, physics is sometimes called the "fundamental science". Physics aims to describe the various phenomena that occur in nature in terms of simpler phenomena. Thus, physics aims to both connect the things observable to humans to root causes, and then connect these causes together. For example, the ancient Chinese observed that certain rocks (lodestone and magnetite) were attracted to one another by an invisible force. This effect was later called magnetism, which was first rigorously studied in the 17th century. But even before the Chinese discovered magnetism, the ancient Greeks knew of other objects such as amber, that when rubbed with fur would cause a similar invisible attraction between the two. This was also first studied rigorously in the 17th century and came to be called electricity. Thus, physics had come to understand two observations of nature in terms of some root cause (electricity and magnetism). However, further work in the 19th century revealed that these two forces were just two different aspects of one force—electromagnetism. This process of "unifying" forces continues today, and electromagnetism and the weak nuclear force are now considered to be two aspects of the electroweak interaction. Physics hopes to find an ultimate reason (theory of everything) for why nature is as it is (see section Current research below for more information). Research fields Contemporary research in physics can be broadly divided into nuclear and particle physics; condensed matter physics; atomic, molecular, and optical physics; astrophysics; and applied physics. Some physics departments also support physics education research and physics outreach. Since the 20th century, the individual fields of physics have become increasingly specialised, and today most physicists work in a single field for their entire careers. "Universalists" such as Einstein (1879–1955) and Lev Landau (1908–1968), who worked in multiple fields of physics, are now very rare. The major fields of physics, along with their subfields and the theories and concepts they employ, are shown in the following table. Nuclear and particle Particle physics is the study of the elementary constituents of matter and energy and the interactions between them. In addition, particle physicists design and develop the high-energy accelerators, detectors, and computer programs necessary for this research. The field is also called "high-energy physics" because many elementary particles do not occur naturally but | computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of industrialization; and advances in mechanics inspired the development of calculus. History The word "physics" comes from , meaning "knowledge of nature". Ancient astronomy Astronomy is one of the oldest natural sciences. Early civilizations dating back before 3000 BCE, such as the Sumerians, ancient Egyptians, and the Indus Valley Civilisation, had a predictive knowledge and a basic awareness of the motions of the Sun, Moon, and stars. The stars and planets, believed to represent gods, were often worshipped. While the explanations for the observed positions of the stars were often unscientific and lacking in evidence, these early observations laid the foundation for later astronomy, as the stars were found to traverse great circles across the sky, which however did not explain the positions of the planets. According to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, and all Western efforts in the exact sciences are descended from late Babylonian astronomy. Egyptian astronomers left monuments showing knowledge of the constellations and the motions of the celestial bodies, while Greek poet Homer wrote of various celestial objects in his Iliad and Odyssey; later Greek astronomers provided names, which are still used today, for most constellations visible from the Northern Hemisphere. Natural philosophy Natural philosophy has its origins in Greece during the Archaic period (650 BCE – 480 BCE), when pre-Socratic philosophers like Thales rejected non-naturalistic explanations for natural phenomena and proclaimed that every event had a natural cause. They proposed ideas verified by reason and observation, and many of their hypotheses proved successful in experiment; for example, atomism was found to be correct approximately 2000 years after it was proposed by Leucippus and his pupil Democritus. Medieval European and Islamic The Western Roman Empire fell in the fifth century, and this resulted in a decline in intellectual pursuits in the western part of Europe. By contrast, the Eastern Roman Empire (also known as the Byzantine Empire) resisted the attacks from the barbarians, and continued to advance various fields of learning, including physics. In the sixth century, Isidore of Miletus created an important compilation of Archimedes' works that are copied in the Archimedes Palimpsest. In sixth-century Europe John Philoponus, a Byzantine scholar, questioned Aristotle's teaching of physics and noted its flaws. He introduced the theory of impetus. Aristotle's physics was not scrutinized until Philoponus appeared; unlike Aristotle, who based his physics on verbal argument, Philoponus relied on observation. On Aristotle's physics Philoponus wrote:But this is completely erroneous, and our view may be corroborated by actual observation more effectively than by any sort of verbal argument. For if you let fall from the same height two weights of which one is many times as heavy as the other, you will see that the ratio of the times required for the motion does not depend on the ratio of the weights, but that the difference in time is a very small one. And so, if the difference in the weights is not considerable, that is, of one is, let us say, double the other, there will be no difference, or else an imperceptible difference, in time, though the difference in weight is by no means negligible, with one body weighing twice as much as the otherPhiloponus' criticism of Aristotelian principles of physics served as an inspiration for Galileo Galilei ten centuries later, during the Scientific Revolution. Galileo cited Philoponus substantially in his works when arguing that Aristotelian physics was flawed. In the 1300s Jean Buridan, a teacher in the faculty of arts at the University of Paris, developed the concept of impetus. It was a step toward the modern ideas of inertia and momentum. Islamic scholarship inherited Aristotelian physics from the Greeks and during the Islamic Golden Age developed it further, especially placing emphasis on observation and a priori reasoning, developing early forms of the scientific method. The most notable innovations were in the field of optics and vision, which came from the works of many scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna. The most notable work was The Book of Optics (also known as Kitāb al-Manāẓir), written by Ibn al-Haytham, in which he conclusively disproved the ancient Greek idea about vision, but also came up with a new theory. In the book, he presented a study of the phenomenon of the camera obscura (his thousand-year-old version of the pinhole camera) and delved further into the way the eye itself works. Using dissections and the knowledge of previous scholars, he was able to begin to explain how light enters the eye. He asserted that the light ray is focused, but the actual explanation of how light projected to the back of the eye had to wait until 1604. His Treatise on Light explained the camera obscura, hundreds of years before the modern development of photography. The seven-volume Book of Optics (Kitab al-Manathir) hugely influenced thinking across disciplines from the theory of visual perception to the nature of perspective in medieval art, in both the East and the West, for more than 600 years. Many later European scholars and fellow polymaths, from Robert Grosseteste and Leonardo da Vinci to René Descartes, Johannes Kepler and Isaac Newton, were in his debt. Indeed, the influence of Ibn al-Haytham's Optics ranks alongside that of Newton's work of the same title, published 700 years later. The translation of The Book of Optics had a huge impact on Europe. From it, later European scholars were able to build devices that replicated those Ibn al-Haytham had built, and understand the way light works. From this, important inventions such as eyeglasses, magnifying glasses, telescopes, and cameras were developed. Classical Physics became a separate science when early modern Europeans used experimental and quantitative methods to discover what are now considered to be the laws of physics. Major developments in this period include the replacement of the geocentric model of the Solar System with the heliocentric Copernican model, the laws governing the motion of planetary bodies (determined by Kepler between 1609 and 1619), Galileo's pioneering work on telescopes and observational astronomy in the 16th and 17th Centuries, and Newton's discovery and unification of the laws of motion and universal gravitation (that would come to bear his name). Newton also developed calculus, the mathematical study of change, which provided new mathematical methods for solving physical problems. The discovery of new laws in thermodynamics, chemistry, and electromagnetics resulted from greater research efforts during the Industrial Revolution as energy needs increased. The laws comprising classical physics remain very widely used for objects on everyday scales travelling at non-relativistic speeds, since they provide a very close approximation in such situations, and theories such as quantum mechanics and the theory of relativity simplify to their classical equivalents at such scales. However, inaccuracies in classical mechanics for very small objects and very high velocities led to the development of modern physics in the 20th century. Modern Modern physics began in the early 20th century with the work of Max Planck in quantum theory and Albert Einstein's theory of relativity. Both of these theories came about due to inaccuracies in classical mechanics in certain situations. Classical mechanics predicted a varying speed of light, which could not be resolved with the constant speed predicted by Maxwell's equations of electromagnetism; this discrepancy was corrected by Einstein's theory of special relativity, which replaced classical mechanics for fast-moving bodies and allowed for a constant speed of light. Black-body radiation provided another problem for classical physics, which was corrected when Planck proposed that the excitation of material oscillators is possible only in discrete steps proportional to their frequency; this, along with the photoelectric effect and a complete theory predicting discrete energy levels of electron orbitals, led to the theory of quantum mechanics taking over from classical physics at very small scales. Quantum mechanics would come to be pioneered by Werner Heisenberg, Erwin Schrödinger and Paul Dirac. From this early work, and work in related fields, the Standard Model of particle physics was derived. Following the discovery of a particle with properties consistent with the Higgs boson at CERN in 2012, all fundamental particles predicted by the standard model, and no others, appear to exist; however, physics beyond the Standard Model, with theories such as supersymmetry, is an active area of research. Areas of mathematics in general are important to this field, such as the study of probabilities and groups. Philosophy In many ways, physics stems from ancient Greek philosophy. From Thales' first attempt to characterize matter, to Democritus' deduction that matter ought to reduce to an invariant state, the Ptolemaic astronomy of a crystalline firmament, and Aristotle's book Physics (an early book on physics, which attempted to analyze and define motion from a philosophical point of view), various Greek philosophers advanced their own theories of nature. Physics was known as natural philosophy until the late 18th century. By the 19th century, physics was realized as a discipline distinct from philosophy and the other sciences. Physics, as with the rest of science, relies on philosophy of science and its "scientific method" to advance our knowledge of the physical world. The scientific method employs a priori reasoning as well as a posteriori reasoning and the use of Bayesian inference to measure the validity of a given theory. The development of physics has answered many questions of early philosophers, but has also raised new questions. Study of the philosophical issues surrounding physics, the philosophy of physics, involves issues such as the nature of space and time, determinism, and metaphysical outlooks such as empiricism, naturalism and realism. Many physicists have written about the philosophical implications of their work, for instance Laplace, who championed causal determinism, and Schrödinger, who wrote on quantum mechanics. The mathematical physicist Roger Penrose had been called a Platonist by Stephen Hawking, a view Penrose discusses in his book, The Road to Reality. Hawking referred to himself as an "unashamed reductionist" and took issue with Penrose's views. Core theories Though physics deals with a wide variety of systems, certain theories are used by all physicists. Each of these theories was experimentally tested numerous times and found to be an adequate approximation of nature. For instance, the theory of classical mechanics accurately describes the motion of objects, provided they are much larger than atoms and moving at much less than the speed of light. These theories continue to be areas of active research today. Chaos theory, a remarkable aspect of classical mechanics, was discovered in the 20th century, three centuries after the original formulation of classical mechanics by Newton (1642–1727). These central theories are important tools for research into more specialised topics, and any physicist, regardless of their specialisation, is expected to be literate in them. These include classical mechanics, quantum mechanics, thermodynamics and statistical mechanics, electromagnetism, and special relativity. Classical Classical physics includes the traditional branches and topics that were recognised and well-developed before the beginning of the 20th century—classical mechanics, acoustics, optics, thermodynamics, and electromagnetism. Classical mechanics is concerned with bodies acted on by forces and bodies in motion and may be divided into statics (study of the forces on a body or bodies not subject to an acceleration), kinematics (study of motion without regard to its causes), and dynamics (study of motion and the forces that affect it); mechanics may also be divided into solid mechanics and fluid mechanics (known together as continuum mechanics), the latter include such branches as hydrostatics, hydrodynamics, aerodynamics, and pneumatics. Acoustics is the study of how sound is produced, controlled, transmitted and received. Important modern branches of acoustics include ultrasonics, the study of sound waves of very high frequency beyond the range of human hearing; bioacoustics, the physics of animal calls and hearing, and electroacoustics, the manipulation of audible sound waves using electronics. Optics, the study of light, is concerned not only with visible light but also with infrared and ultraviolet radiation, which exhibit all of the phenomena of visible light except visibility, e.g., reflection, refraction, interference, diffraction, dispersion, and polarization of light. Heat is a form of energy, the internal energy possessed by the particles of which a substance is composed; thermodynamics deals with the relationships between heat and other forms of energy. Electricity and magnetism have been studied as a single branch of physics since the intimate connection between them was discovered in the early 19th century; an electric current gives rise to a magnetic field, and a changing magnetic field induces an electric current. Electrostatics deals with electric charges at rest, electrodynamics with moving charges, and magnetostatics with magnetic poles at rest. Modern Classical physics is generally concerned with matter and energy on the normal scale of observation, while much of modern physics is concerned with the behavior of matter and energy under extreme conditions or on a very large or very small scale. For example, atomic and nuclear physics study matter on the smallest scale at which chemical elements can be identified. The physics of elementary particles is on an even smaller scale since it is concerned with the most basic units of matter; this branch of physics is also known as high-energy physics because of the extremely high energies necessary to produce many types of particles in particle accelerators. On this scale, ordinary, commonsensical notions of space, time, matter, and energy are no longer valid. The two chief theories of modern physics present a different picture of the concepts of space, time, and matter from that presented by classical physics. Classical mechanics approximates nature as continuous, while quantum theory is concerned with the discrete nature of many phenomena at the atomic and |
"black" magic, until the act was repealed in 2013. An estimated 50–150 alleged witches are killed each year in Papua New Guinea. A Sorcery and Witchcraft Accusation Related National Action Plan (SNAP) was approved by the Government in 2015, although funding and application has been deficient. There are also no protections given to LGBT citizens in the country. Homosexual acts are prohibited by law in Papua New Guinea. Royal PNG Constabulary The Royal Papua New Guinea Constabulary has been troubled in recent years by infighting, political interference and corruption. It was recognised from early after Independence (and hitherto) that a national police force alone could never have the capacity to administer law and order across the country, and that it would also require effective local level systems of policing and enforcement, notably the village court magisterial service. The weaknesses of police capacity, poor working conditions and recommendations to address them were the subject of the 2004 Royal PNG Constabulary Administrative Review to the Minister for Internal Security. In 2011, Commissioner for Police Anthony Wagambie took the unusual step of asking the public to report police asking for payments for performing their duties. In September 2020, Minister for Police Bryan Jared Kramer launched a broadside on Facebook against his own police department, which was subsequently reported in the international media. In the post, Kramer accused the Royal PNG Constabulary of widespread corruption, claiming that "Senior officers based in Police Headquarters in Port Moresby were stealing from their own retired officers’ pension funds. They were implicated in organised crime, drug syndicates, smuggling firearms, stealing fuel, insurance scams, and even misusing police allowances. They misused tens of millions of kina allocated for police housing, resources, and welfare. We also uncovered many cases of senior officers facilitating the theft of Police land." Commissioner for Police David Manning, in a separate statement, said that his force included "criminals in uniform." Administrative divisions Papua New Guinea is divided into four regions, which are not the primary administrative divisions but are quite significant in many aspects of government, commercial, sporting and other activities. The nation has 22 province-level divisions: twenty provinces, the Autonomous Region of Bougainville and the National Capital District. Each province is divided into one or more districts, which in turn are divided into one or more Local-Level Government areas. Provinces are the primary administrative divisions of the country. Provincial governments are branches of the national government as Papua New Guinea is not a federation of provinces. The province-level divisions are as follows: In 2009, Parliament approved the creation of two additional provinces: Hela Province, consisting of part of the existing Southern Highlands Province, and Jiwaka Province, formed by dividing Western Highlands Province. Jiwaka and Hela officially became separate provinces on 17 May 2012. The declaration of Hela and Jiwaka is a result of the largest liquefied natural gas project in the country that is situated in both provinces. The government set 23 November 2019 as the voting date for a non-binding independence referendum in the Bougainville autonomous region. In December 2019, the autonomous region voted overwhelmingly for independence, with 97.7% voting in favour of obtaining full independence and around 1.7% voting in favour of greater autonomy. Geography At , Papua New Guinea is the world's 54th largest country and the 3rd largest island country. Papua New Guinea is part of the Australasian realm, which also includes Australia, New Zealand, eastern Indonesia, and several Pacific island groups, including the Solomon Islands and Vanuatu. Including all its islands, it lies between latitudes 0° and 12°S, and longitudes 140° and 160°E. It has an exclusive economic zone of . The mainland of the country is the eastern half of New Guinea island, where the largest towns are also located, including Port Moresby (capital) and Lae; other major islands within Papua New Guinea include New Ireland, New Britain, Manus and Bougainville. Located north of the Australian mainland, the country's geography is diverse and, in places, extremely rugged. A spine of mountains, the New Guinea Highlands, runs the length of the island of New Guinea, forming a populous highlands region mostly covered with tropical rainforest, and the long Papuan Peninsula, known as the 'Bird's Tail'. Dense rainforests can be found in the lowland and coastal areas as well as very large wetland areas surrounding the Sepik and Fly rivers. This terrain has made it difficult for the country to develop transportation infrastructure. Some areas are accessible only on foot or by aeroplane. The highest peak is Mount Wilhelm at . Papua New Guinea is surrounded by coral reefs which are under close watch, in the interests of preservation. Papua New Guinea's largest rivers are in New Guinea and include Sepik, Ramu, Markham, Musa, Purari, Kikori, Turama, Wawoi and Fly. The country is situated on the Pacific Ring of Fire, at the point of collision of several tectonic plates. Geologically, the island of New Guinea is a northern extension of the Indo-Australian tectonic plate, forming part of a single land mass which is Australia-New Guinea (also called Sahul or Meganesia). It is connected to the Australian segment by a shallow continental shelf across the Torres Strait, which in former ages lay exposed as a land bridge, particularly during ice ages when sea levels were lower than at present. As the Indo-Australian Plate (which includes landmasses of India, Australia, and the Indian Ocean floor in between) drifts north, it collides with the Eurasian Plate. The collision of the two plates pushed up the Himalayas, the Indonesian islands, and New Guinea's Central Range. The Central Range is much younger and higher than the mountains of Australia, so high that it is home to rare equatorial glaciers. There are several active volcanoes, and eruptions are frequent. Earthquakes are relatively common, sometimes accompanied by tsunamis. On 25 February 2018, an earthquake of magnitude 7.5 and depth of 35 kilometres struck the middle of Papua New Guinea. The worst of the damage was centred around the Southern Highlands region. Papua New Guinea is one of the few regions close to the equator that experience snowfall, which occurs in the most elevated parts of the mainland. The border between Papua New Guinea and Indonesia was confirmed by treaty with Australia before independence in 1974. The land border comprises a segment of the 141° E meridian from the north coast southwards to where it meets the Fly River flowing east, then a short curve of the river's thalweg to where it meets the 141°01'10" E meridian flowing west, then southwards to the south coast. The 141° E meridian formed the entire eastern boundary of Dutch New Guinea according to its 1828 annexation proclamation. In 1895 the Dutch and British agreed to a territorial exchange, bringing the entire left bank of the Fly River into British New Guinea and moving the southern border east to the Torasi Estuary. The maritime boundary with Australia was confirmed by a treaty in 1978. In the Torres Strait it runs close to the mainland of New Guinea, keeping the adjacent North Western Torres Strait Islands (Dauan, Boigu and Saibai) under Australian sovereignty. Maritime boundaries with the Solomon Islands were confirmed by a 1989 treaty. Biodiversity Many species of birds and mammals found on New Guinea have close genetic links with corresponding species found in Australia. One notable feature in common for the two landmasses is the existence of several species of marsupial mammals, including some kangaroos and possums, which are not found elsewhere. Papua New Guinea is a megadiverse country. Many of the other islands within PNG territory, including New Britain, New Ireland, Bougainville, the Admiralty Islands, the Trobriand Islands, and the Louisiade Archipelago, were never linked to New Guinea by land bridges. As a consequence, they have their own flora and fauna; in particular, they lack many of the land mammals and flightless birds that are common to New Guinea and Australia. Australia and New Guinea are portions of the ancient supercontinent of Gondwana, which started to break into smaller continents in the Cretaceous period, 65–130 million years ago. Australia finally broke free from Antarctica about 45 million years ago. All the Australasian lands are home to the Antarctic flora, descended from the flora of southern Gondwana, including the coniferous podocarps and Araucaria pines, and the broad-leafed southern beech (Nothofagus). These plant families are still present in Papua New Guinea. New Guinea is part of the humid tropics, and many Indomalayan rainforest plants spread across the narrow straits from Asia, mixing together with the old Australian and Antarctic floras. New Guinea has been identified as the world's most floristically diverse island in the world, with 13,634 known species of vascular plants. PNG includes a number of terrestrial ecoregions: Admiralty Islands lowland rain forests – forested islands to the north of the mainland, home to a distinct flora. Central Range montane rain forests Huon Peninsula montane rain forests Louisiade Archipelago rain forests New Britain-New Ireland lowland rain forests New Britain-New Ireland montane rain forests New Guinea mangroves Northern New Guinea lowland rain and freshwater swamp forests Northern New Guinea montane rain forests Solomon Islands rain forests (includes Bougainville Island and Buka) Southeastern Papuan rain forests Southern New Guinea freshwater swamp forests Southern New Guinea lowland rain forests Trobriand Islands rain forests Trans-Fly savanna and grasslands Central Range sub-alpine grasslands Three new species of mammals were discovered in the forests of Papua New Guinea by an Australian-led expedition in the early 2010s. A small wallaby, a large-eared mouse and shrew-like marsupial were discovered. The expedition was also successful in capturing photographs and video footage of some other rare animals such as the Tenkile tree kangaroo and the Weimang tree kangaroo. Nearly one quarter of Papua New Guinea's rainforests were damaged or destroyed between 1972 and 2002. Papua New Guinea had a Forest Landscape Integrity Index mean score of 8.84/10, ranking it 17th globally out of 172 countries. Mangrove swamps stretch along the coast, and in the inland it is inhabited by nipa palm (Nypa fruticans), and deeper in the inland the sago palm tree inhabits areas in the valleys of larger rivers. Trees such as oaks, red cedars, pines, beeches are becoming predominantly present in the uplands above 3,300 feet. Papua New Guinea is rich in various species of reptiles, indigenous freshwater fish and birds, but it is almost devoid of large mammals. Climate The climate on the island is essentially tropical, but it varies by region. The maximum mean temperature in the lowlands is 30 to 32 °C, and the minimum 23-24 °C. In the highlands above 2100 meters, colder conditions prevail and night frosts are common there, while the daytime temperature exceeds 22 °C, regardless of the season. Economy Papua New Guinea is richly endowed with natural resources, including mineral and renewable resources, such as forests, marine (including a large portion of the world's major tuna stocks), and in some parts agriculture. The rugged terrain—including high mountain ranges and valleys, swamps and islands—and high cost of developing infrastructure, combined with other factors (including law and order problems in some centres and the system of customary land title) makes it difficult for outside developers. Local developers are hindered by years of deficient investment in education, health, and access to finance. Agriculture, for subsistence and cash crops, provides a livelihood for 85% of the population and continues to provide some 30% of GDP. Mineral deposits, including gold, oil, and copper, account for 72% of export earnings. Oil palm production has grown steadily over recent years (largely from estates and with extensive outgrower output), with palm oil now the main agricultural export. Coffee remains the major export crop (produced largely in the Highlands provinces); followed by cocoa and coconut oil/copra from the coastal areas, each largely produced by smallholders; tea, produced on estates; and rubber. The Iagifu/Hedinia Field was discovered in 1986 in the Papuan fold and thrust belt. Former Prime Minister Sir Mekere Morauta tried to restore integrity to state institutions, stabilise the kina, restore stability to the national budget, privatise public enterprises where appropriate, and ensure ongoing peace on Bougainville following the 1997 agreement which ended Bougainville's secessionist unrest. The Morauta government had considerable success in attracting international support, specifically gaining the backing of the International Monetary Fund (IMF) and the World Bank in securing development assistance loans. As of 2019, PNG's real GDP growth rate was 3.8%, with an inflation rate of 4.3% This economic growth has been primarily attributed to strong commodity prices, particularly mineral but also agricultural, with the high demand for mineral products largely sustained even during the crisis by the buoyant Asian markets, a booming mining sector and by a buoyant outlook and the construction phase for natural gas exploration, production, and exportation in liquefied form (liquefied natural gas or "LNG") by LNG tankers, all of which will require multibillion-dollar investments (exploration, production wells, pipelines, storage, liquefaction plants, port terminals, LNG tanker ships). The first major gas project was the PNG LNG joint venture. ExxonMobil is operator of the joint venture, also comprising PNG company Oil Search, Santos, Kumul Petroleum Holdings (Papua New Guinea's national oil and gas company), JX Nippon Oil and Gas Exploration, the PNG government's Mineral Resources Development Company and Petromin PNG Holdings. The project is an integrated development that includes gas production and processing facilities in the Hela, Southern Highlands and Western Provinces of Papua New Guinea, including liquefaction and storage facilities (located northwest of Port Moresby) with capacity of 6.9 million tonnes per year. There are over of pipelines connecting the facilities. It is the largest private-sector investment in the history of PNG. A second major project is based on initial rights held by the French oil and gas major Total S.A. and the U.S. company InterOil Corp. (IOC), which have partly combined their assets after Total agreed in December 2013 to purchase 61.3% of IOC's Antelope and Elk gas field rights, with the plan to develop them starting in 2016, including the construction of a liquefaction plant to allow export of LNG. Total S.A. has separately another joint operating agreement with Oil Search . Further gas and mineral projects are proposed (including the large Wafi-Golpu copper-gold mine), with extensive exploration ongoing across the country. The PNG government's long-term Vision 2050 and shorter-term policy documents, including the 2013 Budget and the 2014 Responsible Sustainable Development Strategy, emphasise the need for a more diverse economy, based upon sustainable industries and avoiding the effects of Dutch disease from major resource extraction projects undermining other industries, as has occurred in many countries experiencing oil or other mineral booms, notably in Western Africa, undermining much of their agriculture sector, manufacturing and tourism, and with them broad-based employment prospects. Measures have been taken to mitigate these effects, including through the establishment of a sovereign wealth fund, partly to stabilise revenue and expenditure flows, but much will depend upon the readiness to make real reforms to effective use of revenue, tackling rampant corruption and empowering households and businesses to access markets, services and develop a more buoyant economy, with lower costs, especially for small to medium-size enterprises. One major project conducted through the PNG Department for Community Development suggested that other pathways to sustainable development should be considered. The Institute of National Affairs, a PNG independent policy think tank, provides a report on the business and investment environment of Papua New Guinea every five years, based upon a survey of large and small, local and overseas companies, highlighting law and order problems and corruption, as the worst impediments, followed by the poor state of transport, power and communications infrastructure. Land tenure The PNG legislature has enacted laws in which a type of tenure called "customary land title" is recognised, meaning that the traditional lands of the indigenous peoples have some legal basis to inalienable tenure. This customary land notionally covers most of the usable land in the country (some 97% of total land area); alienated land is either held privately under state lease or is government land. Freehold title (also known as fee simple) can only be held by Papua New Guinean citizens. Only some 3% of the land of Papua New Guinea is in private hands; this is privately held under 99-year state lease, or it is held by the State. There is virtually no freehold title; the few existing freeholds are automatically converted to state lease when they are transferred between vendor and purchaser. Unalienated land is owned under customary title by traditional landowners. The precise nature of the seisin varies from one culture to another. Many writers portray land as in the communal ownership of traditional clans; however, closer studies usually show that the smallest portions of land whose ownership cannot be further divided are held by the individual heads of extended families and their descendants or their descendants alone if they have recently died. This is a matter of vital importance because a problem of economic development is identifying the membership of customary landowning groups and the owners. Disputes between mining and forestry companies and landowner groups often devolve on the issue of whether the companies entered into contractual relations for the use of land with the true owners. Customary property—usually land—cannot be devised by will. It can only be inherited according to the custom of the deceased's people. The Lands Act was amended in 2010 along with the Land Group Incorporation Act, intended to improve the management of state land, mechanisms for dispute resolution over land, and to enable customary landowners to be better able to access finance and possible partnerships over portions of their land, if they seek to develop it for urban or rural economic activities. The Land Group Incorporation Act requires more specific identification of the customary landowners than hitherto and their more specific authorisation before any land arrangements are determined; (a major issue in recent years has been a land grab, using, or rather misusing, the Lease-Leaseback provision under the Land Act, notably using 'Special Agricultural and Business Leases' (SABLs) to acquire vast tracts of customary land, purportedly for agricultural projects, but in an almost all cases as a back-door mechanism for securing tropical forest resources for logging—circumventing the more exacting requirements of the Forest Act, for securing Timber Permits (which must comply with sustainability requirements and be competitively secured, and with the customary landowners approval). Following a national outcry, these SABLs have been subject to a Commission of Inquiry, established in mid-2011, for which the report is still awaited for initial presentation to the Prime Minister and Parliament. Demographics Papua New Guinea is one of the most heterogeneous nations in the world with an estimated 8.95 million inhabitants as of 2020. There are hundreds of ethnic groups indigenous to Papua New Guinea, the majority being from the group known as Papuans, whose ancestors arrived in the New Guinea region tens of thousands of years ago. The other indigenous peoples are Austronesians, their ancestors having arrived in the region less than four thousand years ago. There are also numerous people from other parts of the world now resident, including Chinese, Europeans, Australians, Indonesians, Filipinos, Polynesians, and Micronesians (the last four belonging to the Austronesian family). Around 40,000 expatriates, mostly from Australia and China, were living in Papua New Guinea in 1975. 20,000 people | finance and possible partnerships over portions of their land, if they seek to develop it for urban or rural economic activities.

Around 40,000 expatriates, mostly from Australia and China, were living in Papua New Guinea in 1975. 20,000 people from Australia currently live in Papua New Guinea. They represent 0.25% of the total population of Papua New Guinea. Urbanisation According to the CIA World Factbook (2018), Papua New Guinea has the second lowest urban population percentage in the world, with 13.2%, only behind Burundi. The geography and economy of Papua New Guinea are the main factors behind the low percentage. Papua New Guinea has an urbanisation rate of 2.51%, measured as the projected change in urban population from 2015 to 2020. Languages Papua New Guinea has more languages than any other country, with over 820 indigenous languages, representing 12% of the world's total, but most have fewer than 1,000 speakers. With an average of only 7,000 speakers per language, Papua New Guinea has a greater density of languages than any other nation on earth except Vanuatu. The most widely spoken indigenous language is Enga, with about 200,000 speakers, followed by Melpa and Huli. Indigenous languages are classified into two large groups, Austronesian languages and non-Austronesian, or Papuan, languages. There are four languages in Papua New Guinea with some statutory recognition: English, Tok Pisin, Hiri Motu, and, since 2015, sign language (which in practice means Papua New Guinean Sign Language). English is the language of government and the education system, but it is not spoken widely. The primary lingua franca of the country is Tok Pisin (commonly known in English as New Guinean Pidgin or Melanesian Pidgin), in which much of the debate in Parliament is conducted, many information campaigns and advertisements are presented, and a national weekly newspaper, Wantok, is published. The only area where Tok Pisin is not prevalent is the southern region of Papua, where people often use the third official language, Hiri Motu. Although it lies in the Papua region, Port Moresby has a highly diverse population which primarily uses Tok Pisin, and to a lesser extent English, with Motu spoken as the indigenous language in outlying villages. Health Life expectancy in Papua New Guinea at birth was 64 years for men in 2016 and 68 for women. Government expenditure health in 2014 accounted for 9.5% of total government spending, with total health expenditure equating to 4.3% of GDP. There were five physicians per 100,000 people in the early 2000s. The 2010 maternal mortality rate per 100,000 births for Papua New Guinea was 250. This is compared with 311.9 in 2008 and 476.3 in 1990. The under-5 mortality rate, per 1,000 births is 69 and the neonatal mortality as a percentage of under-5s' mortality is 37. In Papua New Guinea, the number of midwives per 1,000 live births is 1 and the lifetime risk of death for pregnant women is 1 in 94. Religion The government and judiciary uphold the constitutional right to freedom of speech, thought, and belief, and no legislation to curb those rights has been adopted. The 2011 census found that 95.6% of citizens identified themselves as Christian, 1.4% were not Christian, and 3.1% gave no answer. Virtually no respondent identified as being nonreligious. Religious syncretism is high, with many citizens combining their Christian faith with some traditional indigenous religious practices. Most Christians in Papua New Guinea are Protestants, constituting roughly 70% of the total population. They are mostly represented by the Evangelical Lutheran Church of Papua New Guinea, the Seventh-day Adventist Church, diverse Pentecostal denominations, the United Church in Papua New Guinea and Solomon Islands, the Evangelical Alliance Papua New Guinea, and the Anglican Church of Papua New Guinea. Apart from Protestants, there is a notable Roman Catholic minority with approximately 25% of the population. There are approximately 2,000 Muslims in the country. The majority belong to the Sunni group, while a small number are Ahmadi. Non-traditional Christian churches and non-Christian religious groups are active throughout the country. The Papua New Guinea Council of Churches has stated that both Muslim and Confucian missionaries are highly active. Traditional religions are often animist. Some also tend to have elements of veneration of the dead, though generalisation is suspect given the extreme heterogeneity of Melanesian societies. Prevalent among traditional tribes is the belief in masalai, or evil spirits, which are blamed for "poisoning" people, causing calamity and death, and the practice of puripuri (sorcery). The first Bahá’í in PNG was Violete Hoenke who arrived at Admiralty Island, from Australia, in 1954. The PNG Bahá’í community grew so quickly that in 1969 a National Spiritual Assembly (administrative council) was elected. As of 2020 there are over 30,000 members of the Bahá’í Faith in PNG. In 2012 the decision was made to erect the first Bahá’í House of Worship in PNG. Its design is that of a woven basket, a common feature of all groups and cultures in PNG. It is, therefore, hoped to be a symbol for the entire country. Its nine entrances are inspired by the design of Haus Tambaran (Spirit House). Construction began in Port Moresby in 2018. Culture It is estimated that more than one thousand cultural groups exist in Papua New Guinea. Because of this diversity, many styles of cultural expression have emerged. Each group has created its own expressive forms in art, dance, weaponry, costumes, singing, music, architecture and much more. Most of these cultural groups have their own language. People typically live in villages that rely on subsistence farming. In some areas people hunt and collect wild plants (such as yam roots and karuka) to supplement their diets. Those who become skilled at hunting, farming and fishing earn a great deal of respect. Seashells are no longer the currency of Papua New Guinea, as they were in some regions—sea shells were abolished as currency in 1933. This tradition is still present in local customs. In some cultures, to get a bride, a groom must bring a certain number of golden-edged clam shells as a bride price. In other regions, the bride price is paid in lengths of shell money, pigs, cassowaries or cash. Elsewhere, it is brides who traditionally pay a dowry. People of the highlands engage in colourful local rituals that are called "sing sings". They paint themselves and dress up with feathers, pearls and animal skins to represent birds, trees or mountain spirits. Sometimes an important event, such as a legendary battle, is enacted at such a musical festival. The country possesses one UNESCO World Heritage Site, the Kuk Early Agricultural Site, which was inscribed in 2008. The country, however, has no elements inscribed yet in the UNESCO Intangible Cultural Heritage Lists, despite having one of the widest array of intangible cultural heritage elements in the world. Sport Sport is an important part of Papua New Guinean culture, and rugby league is by far the most popular sport. In a nation where communities are far apart and many people live at a minimal subsistence level, rugby league has been described as a replacement for tribal warfare as a way of explaining the local enthusiasm for the game. Many Papua New Guineans have become celebrities by representing their country or playing in an overseas professional league. Even Australian rugby league players who have played in the annual State of Origin series, which is celebrated every year in PNG, are among the most well-known people throughout the nation. State of Origin is a highlight of the year for most Papua New Guineans, although the support is so passionate that many people have died over the years in violent clashes supporting their team. The Papua New Guinea national rugby league team usually plays against the Australian Prime Minister's XIII (a selection of NRL players) each year, normally in Port Moresby. Although not as popular, Australian rules football is more significant in another way, as the national team is ranked second, only after Australia. Other major sports which have a part in the Papua New Guinea sporting landscape are association football, rugby union, basketball and, in eastern Papua, cricket. Education A large proportion of the population is illiterate, with women predominating in this area. Much of the education in PNG is provided by church institutions. This includes 500 schools of the Evangelical Lutheran Church of Papua New Guinea. Papua New Guinea has six universities apart from other major tertiary institutions. The two founding universities are the University of Papua New Guinea, based in the National Capital District, and the Papua New Guinea University of Technology, based outside of Lae, in Morobe Province. The four other universities which were once colleges were established recently after gaining government recognition. These are the University of Goroka in the Eastern Highlands province, Divine Word University (run by the Catholic Church's Divine Word Missionaries) in Madang Province, Vudal University in East New Britain Province and Pacific Adventist University (run by the Seventh-day Adventist Church) in the National Capital District. Science and technology Papua New Guinea's National Vision 2050 was adopted in 2009. This has led to the establishment of the Research, Science and Technology Council. At its gathering in November 2014, the Council re-emphasised the need to focus on sustainable development through science and technology. Vision 2050's medium-term priorities are: emerging industrial technology for downstream processing; infrastructure technology for the economic corridors; knowledge-based technology; science and engineering education; and to reach the target of investing 5% of GDP in research and development by 2050. (Papua New Guinea invested 0.03% of GDP in research and development in 2016.) In 2016, women accounted for 33.2% of researchers in Papua New Guinea. According to Thomson Reuters' Web of Science, Papua New Guinea had the largest number of publications (110) among Pacific Island states in 2014, followed by Fiji (106). Nine out of ten scientific publications from Papua New Guinea focused on immunology, genetics, biotechnology and microbiology. Nine out of ten were also co-authored by scientists from other countries, mainly Australia, the United States of America, United Kingdom, Spain and Switzerland. In 2019, Papua New Guinea took second place among Pacific Island states with 253 publications, behind Fiji with 303 publications, in the Scopus (Elsevier) database of scientific publications. Health sciences accounted for 49% of these publications. Papua New Guinea's top scientific collaborators over 2017 to 2019 were Australia, the United States of America, United Kingdom, France and India. Forestry is an important economic resource for Papua New Guinea, but the industry uses low and semi-intensive technological inputs. As a result, product ranges are limited to sawed timber, veneer, plywood, block board, moulding, poles and posts and wood chips. Only a few limited finished products are exported. Lack of automated machinery, coupled with inadequately trained local technical personnel, are some of the obstacles to introducing automated machinery and design. Renewable energy sources represent two-thirds of the total electricity supply. In 2015, the Secretariat of the Pacific Community observed that, 'while Fiji, Papua New Guinea, and Samoa are leading the way with large-scale hydropower projects, there is enormous potential to expand the deployment of other renewable energy options such as solar, wind, geothermal and ocean-based energy sources'. The European Union funded the Renewable Energy in Pacific Island Countries Developing Skills and Capacity programme (EPIC) over 2013 to 2017. The programme developed a master's programme in renewable energy management, accredited in 2016, at the University of Papua New Guinea and helped to establish a Centre of Renewable Energy at the same university. Papua New Guinea is one of the 15 beneficiaries of a programme on Adapting to Climate Change and Sustainable Energy worth €37.26 million. The programme resulted from the signing of an agreement in February 2014 between the European Union and the Pacific Islands Forum Secretariat. The other beneficiaries are the Cook Islands, Fiji, Kiribati, Marshall Islands, Federated States of Micronesia, Nauru, Niue, Palau, Samoa, Solomon Islands, Timor-Leste, Tonga, Tuvalu and Vanuatu. Transport Transport in Papua New Guinea is heavily limited by the country's mountainous terrain. As a result, air travel is the single most important form of transport for human and high density/value freight. Aeroplanes made it possible to open up the country during its early colonial period. Even today the two largest cities, Port Moresby and Lae, are only directly connected by planes. Port Moresby is not linked by road to any of the other major towns, and many remote villages can only be reached by light aircraft or on foot. Jacksons International Airport is the major international airport in Papua New Guinea, located from Port Moresby. In addition to two international airfields, Papua New Guinea has 578 airstrips, most of which are unpaved.

"related with the bull". Mythology Birth Poseidon was the second son of the Titans Cronus and Rhea. In most accounts he is swallowed by Cronus at birth and is later saved, along with his other siblings, by Zeus. However, in some versions of the story, he, like his brother Zeus, did not share the fate of his other brother and sisters who were eaten by Cronus. He was saved by his mother Rhea, who concealed him among a flock of lambs and pretended to have given birth to a colt, which she gave to Cronus to devour. According to John Tzetzes the kourotrophos, or nurse of Poseidon was Arne, who denied knowing where he was, when Cronus came searching; according to Diodorus Siculus Poseidon was raised by the Telchines on Rhodes, just as Zeus was raised by the Korybantes on Crete. According to a single reference in the Iliad, when the world was divided by lot in three, Zeus received the sky, Hades the underworld and Poseidon the sea. In Homer's Odyssey, Poseidon has a home in Aegae. Foundation of Athens Athena became the patron goddess of the city of Athens after a competition with Poseidon. Yet Poseidon remained a numinous presence on the Acropolis in the form of his surrogate, Erechtheus. At the dissolution festival at the end of the year in the Athenian calendar, the Skira, the priests of Athena and the priest of Poseidon would process under canopies to Eleusis. They agreed that each would give the Athenians one gift and the Athenians would choose whichever gift they preferred. Poseidon struck the ground with his trident and a spring sprang up; the water was salty and not very useful, whereas Athena offered them an olive tree. The Athenians or their king, Cecrops, accepted the olive tree and along with it Athena as their patron, for the olive tree brought wood, oil and food. After the fight, infuriated at his loss, Poseidon sent a monstrous flood to the Attic Plain, to punish the Athenians for not choosing him. The depression made by Poseidon's trident and filled with salt water was surrounded by the northern hall of the Erechtheum, remaining open to the air. "In cult, Poseidon was identified with Erechtheus," Walter Burkert noted; "the myth turns this into a temporal-causal sequence: in his anger at losing, Poseidon led his son Eumolpus against Athens and killed Erectheus." The contest of Athena and Poseidon was the subject of the reliefs on the western pediment of the Parthenon, the first sight that greeted the arriving visitor. This myth is construed by Robert Graves and others as reflecting a clash between the inhabitants during Mycenaean times and newer immigrants. Athens at its height was a significant sea power, at one point defeating the Persian fleet at Salamis Island in a sea battle. Walls of Troy Poseidon and Apollo, having offended Zeus by their rebellion in Hera's scheme, were temporarily stripped of their divine authority and sent to serve King Laomedon of Troy. He had them build huge walls around the city and promised to reward them with his immortal horses, a promise he then refused to fulfill. In vengeance, before the Trojan War, Poseidon sent a sea monster to attack Troy. The monster was later killed by Heracles. Consort, lovers, victims and children Poseidon was said to have had many lovers of both sexes (see expandable list below). His consort was Amphitrite, a nymph and ancient sea-goddess, daughter of Nereus and Doris. Together they had a son named Triton, a merman. Poseidon was the father of many heroes. He is thought to have fathered the famed Theseus. A mortal woman named Tyro was married to Cretheus (with whom she had one son, Aeson), but loved Enipeus, a river god. She pursued Enipeus, who refused her advances. One day, Poseidon, filled with lust for Tyro, disguised himself as Enipeus, and from their union were born the heroes Pelias and Neleus, twin boys. Poseidon also had an affair with Alope, his granddaughter through Cercyon, his son and King of Eleusis, begetting the Attic hero Hippothoon. Cercyon had his daughter buried alive but Poseidon turned her into the spring, Alope, near Eleusis. Poseidon rescued Amymone from a lecherous satyr and then fathered a child, Nauplius, by her. After having raped Caeneus, Poseidon fulfilled her request and changed her into a male warrior. A mortal woman named Cleito once lived on an isolated island; Poseidon fell in love with the human mortal and created a dwelling sanctuary at the top of a hill near the middle of the island and surrounded the dwelling with rings of water and land to protect her. She gave birth to five sets of twin boys; the firstborn, Atlas, became the first ruler of Atlantis. Not all of Poseidon's children were human. In an archaic myth, Poseidon once pursued Demeter. She spurned his advances, turning herself into a mare so that she could hide in a herd of horses; he saw through the deception and became a stallion and captured her. Their child was a horse, Arion, which was capable of human speech. Poseidon also raped Medusa on the floor of a temple to Athena. Medusa was then changed into a monster by Athena. When she was later beheaded by the hero Perseus, Chrysaor and Pegasus emerged from her neck. His other children include Polyphemus (the Cyclops) and, finally, Alebion and Bergion and Otos and Ephialtae (the giants). The philosopher Plato was held by his fellow ancient Greeks to have traced his descent to the sea-God Poseidon through his father Ariston and his mythic predecessors the demigod kings Codrus and Melanthus. Male lovers included Nerites, Pelops and Patroclus. <div style=display:inline-table> {| class="wikitable sortable" |+Offspring and mothers, Table 1 ! scope="col" style="width: 230pt;" | Offspring ! scope="col" style="width: 130pt;" | Mother |- |Triton, Benthesicyme, Rhodos |Amphitrite |- |Antaeus, Charybdis, Laistryon |Gaea |- |Despoina, Arion |Demeter |- |Rhodos, Herophile |Aphrodite |- |Pegasus, Chrysaor |Medusa |- |Ergiscus |Aba |- |Aethusa, Hyrieus, Hyperenor, Hyperes.

He was associated with dolphins and three-pronged fish spears (tridents). He lived in a palace on the ocean floor, made of coral and gems. In the Iliad Poseidon favors the Greeks, and on several occasion takes an active part in the battle against the Trojan forces. However, in Book XX he rescues Aeneas after the Trojan prince is laid low by Achilles. In the Odyssey, Poseidon is notable for his hatred of Odysseus who blinded the god's son, the Cyclops Polyphemus. The enmity of Poseidon prevents Odysseus's return home to Ithaca for many years. Odysseus is even told, notwithstanding his ultimate safe return, that to placate the wrath of Poseidon will require one more voyage on his part. In the Aeneid, Neptune is still resentful of the wandering Trojans, but is not as vindictive as Juno, and in Book I he rescues the Trojan fleet from the goddess's attempts to wreck it, although his primary motivation for doing this is his annoyance at Juno's having intruded into his domain. A hymn to Poseidon included among the Homeric Hymns is a brief invocation, a seven-line introduction that addresses the god as both "mover of the earth and barren sea, god of the deep who is also lord of Helicon and wide Aegae, and specifies his twofold nature as an Olympian: "a tamer of horses and a saviour of ships." In modern culture Movies and television Poseidon has been very popular especially in god-related films. John Putch directed the movie The Poseidon Adventure. Wolfgang Petersen also film adapted Paul Gallico's novel and directed the movie Poseidon. Poseidon appears in Percy Jackson and the Olympians as the father of Percy Jackson and Tyson the Cyclops. He also appears in the ABC television series Once Upon a Time as the guest star of the second half of season four played by Ernie Hudson. In this version, Poseidon is portrayed as the father of the Sea Witch Ursula. Military Many military weapons from multiple countries have been named after Poseidon. Such examples are the P8 Poseidon, & the "Poseidon" which is a Russian nuclear-armed unmanned underwater vehicle.

According to Pausanias, Poseidon was one of the caretakers of the oracle at Delphi before Olympian Apollo took it over. Apollo and Poseidon worked closely in many realms: in colonization, for example, Delphic Apollo provided the authorization to go out and settle, while Poseidon watched over the colonists on their way, and provided the lustral water for the foundation-sacrifice. Xenophon's Anabasis describes a group of Spartan soldiers in 400–399 BC singing to Poseidon a paean—a kind of hymn normally sung for Apollo. Like Dionysus, who inflamed the maenads, Poseidon also caused certain forms of mental disturbance. A Hippocratic text of ca 400 BC, On the Sacred Disease says that he was blamed for certain types of epilepsy. Poseidon is still worshipped today in modern Hellenic religion, among other Greek gods. The worship of Greek gods has been recognized by the Greek government since 2017. Epithets and attributes Poseidon had a variety of roles, duties and attributes. He is a separate deity from the oldest Greek god of the sea Pontus. In Athens his name is superimposed οn the name of the non-Greek god Erechtheus (Poseidon Erechtheus). In Iliad he is the lord of the sea and his palace is built in Aegai, in the depth of the sea. His significance is indicated by his titles Eurykreion () "wide-ruling", an epithet also applied to Agamemnon and Helikonios anax (), "lord of Helicon or Helike" In Helike of Achaia he was specially honoured. Anax is identified in Mycenaean Greek (Linear B) as wa-na-ka,a title of Poseidon as king of the underworld. Aeschylus uses also the epithet anax and Pindar the epithet Eurymedon () "widely ruling". Some of the epithets (or adjectives) applied to him like Enosigaios (), Enosichthon () (Homer) and Ennosidas () (Pindar) , mean "earth shaker". These epithets indicate his chthonic nature, and have an older evidence of use, as it is identified in Linear B, as , E-ne-si-da-o-ne. Other epithets that relate him with the earthquakes are Gaieochos () and Seisichthon () The god who causes the earthquakes is also the protector against them, and he had the epithets Themeliouchos () "upholding the foundations" , Asphaleios () "securer, protector" with a temble at Tainaron. Pausanias describes a sanctuary of Poseidon near Sparta beside the shrine of Alcon, where he had the surname Domatites (), "of the house" Homer uses for Poseidon the title Kyanochaites () , "dark-haired, dark blue of the sea". Epithets like Pelagios () "of the open sea", Aegeus () ,"of the high sea" in the town of Aegae in Euboea, where he had a magnificent temple upon a hill, Pontomedon ()," lord of the sea" (Pindar , Aeschylus) and Kymothales (), "abounding with waves", indicate that Poseidon was regarded as holding sway over the sea. Other epithets that relate him with the sea are , Porthmios (), "of strait, narrow sea" at Karpathos, Epactaeus () "god worshipped on the coast", in Samos., Alidoupos, () "sea resounding". His symbol is the trident and he has the epithet Eutriaina (), "with goodly trident" (Pindar). The god of the sea is also the god of fishing , and tuna was his attribute. At Lampsacus they offered fishes to Poseidon and he had the epithet phytalmios () His epithet Phykios (), "god of seaweeds" at Mykonos, seems to be related with fishing. He had a fest where women were not allowed, with special offers also to Poseidon Temenites () "related to an official domain ". At the same day they made offers to Demeter Chloe therefore Poseidon was the promotor of vegetation. He had the epithet phytalmios () at Myconos, Troizen, Megara and Rhodes, comparable with Ptorthios () at Chalcis. Poseidon had a close association with horses. He is known under the epithet Hippios () ,"of a horse or horses" usually in Arcadia. He had temples at Lycosura, Mantineia, Methydrium, Pheneos, Pallandion. At Lycosura he is related with the cult of Despoina. The modern sanctuary near Mantineia was built by Emperor Hadrian. In Athens on the hill of horses there was the altar of Poseidon Hippios and Athena Hippia. The temple of Poseidon was destroyed by Antigonus when he attacked Attica. He is usually the tamer of horses (Damaios , at Corinth), and the tender of horses Hippokourios ) at Sparta, where he had a sanctuary near the sanctuary of Artemis Aiginea. In some myths he is the father of horses, either by spilling his seed upon a rock or by mating with a creature who then gave birth to the first horse. In Thessaly he had the title Petraios , "of the rocks". He hit a rock and the first horse "Skyphios" appeared. He was closely related with the springs, and with the strike of his trident, he created springs. He had the epithets Krenouchos (), "ruling over springs", and nymphagetes () "leader of the nymphs" On the Acropolis of Athens he created the saltspring Sea of Erechtheus (). Many springs like Hippocrene and Aganippe in Helikon are related with the word horse (hippos). (also Glukippe, Hyperippe). He is the father of Pegasus, whose name is deriven from , (pēgē) "spring". Epithets like Genesios at Lerna Genethlios () "of the race or family" Phratrios () "of the brotherhood", and Patrigenios () indicate his relation with the genealogy trees and the brotherhood. Other epithets of Poseidon in local cults are Epoptes () , "overseer, watcher" at Megalopolis, Empylios (), "at the gate " at Thebes., Kronios () (Pindar) and semnos (), "august, holy" (Sophocles). The cult of Poseidon is oftenly related with festivals. At Corinth the Isthmian games was an athletic and music festival to honour the god who had the epithet Isthmios (). The Amphictiony of Kalaureia belonged to him. At Tainaron he had a famous temple and festival. Other games which belonged to him are the Pohoidaia () in Helos and Thuria and the race in Gaiaochō () Poseidon Gaieochos () had a temple near Sparta beside an Hippodrome. Τhe epithet probably means " the one who moves under the earth" ' and therefore shakes the earth. This seem to relate Poseidon with the rivers at Peloponnesus that seem to disappear and then flow under the earth. At Ephesus there was a fest "Tavria" and he had the epithet Tavreios (), "related with the bull". Mythology Birth Poseidon was the second son of the Titans Cronus and Rhea. In most accounts he is swallowed by Cronus at birth and is later saved, along with his other siblings, by Zeus. However, in some versions of the story, he, like his brother Zeus, did not share the fate of his other brother and sisters who were eaten by Cronus. He was saved by his mother Rhea, who concealed him among a flock of lambs and pretended to have given birth to a colt, which she gave to Cronus to devour. According to John Tzetzes the kourotrophos, or nurse of Poseidon was Arne, who denied knowing where he was, when Cronus came searching; according to Diodorus Siculus Poseidon was raised by the Telchines on Rhodes, just as Zeus was raised by the Korybantes on Crete. According to a single reference in the Iliad, when the world was divided by lot in three, Zeus received the sky, Hades the underworld and Poseidon the sea. In Homer's Odyssey, Poseidon has a home in Aegae. Foundation of Athens Athena became the patron goddess of the city of Athens after a competition with Poseidon. Yet Poseidon remained a numinous presence on the Acropolis in the form of his surrogate, Erechtheus. At the dissolution festival at the end of the year in the Athenian calendar, the Skira, the priests of Athena and the priest of Poseidon would process under canopies to Eleusis. They agreed that each would give the Athenians one gift and the Athenians would choose whichever gift they preferred. Poseidon struck the ground with his trident and a spring sprang up; the water was salty and not very useful, whereas Athena offered them an olive tree. The Athenians or their king, Cecrops, accepted the olive tree and along with it Athena as their patron, for the olive tree brought wood, oil and food. After the fight, infuriated at his loss, Poseidon sent a monstrous flood to the Attic Plain, to punish the Athenians for not choosing him. The depression made by Poseidon's trident and filled with salt water was surrounded by the northern hall of the Erechtheum, remaining open to the air. "In cult, Poseidon was identified with Erechtheus," Walter Burkert noted; "the myth turns this into a temporal-causal sequence: in his anger at losing, Poseidon led his son Eumolpus against Athens and killed Erectheus." The contest of Athena and Poseidon was the subject of the reliefs on the western pediment of the Parthenon, the first sight that greeted the arriving visitor. This myth is construed by Robert Graves and others as reflecting a clash between the inhabitants during Mycenaean times and newer immigrants. Athens at its height was a significant sea power, at one point defeating the Persian fleet at Salamis Island in a sea battle. Walls of Troy Poseidon and Apollo, having offended Zeus by their rebellion in Hera's scheme, were temporarily stripped of their divine authority and sent to serve King Laomedon of Troy. He had them build huge walls around the city and promised to reward them with his immortal horses, a promise he then refused to fulfill. In vengeance, before the Trojan War, Poseidon sent a sea monster to attack Troy. The monster was later killed by Heracles. Consort, lovers, victims and children Poseidon was said to have had many lovers of both sexes (see expandable list below). His consort was Amphitrite, a nymph and ancient sea-goddess, daughter of Nereus and Doris. Together they had a son named Triton, a merman. Poseidon was the father of many heroes. He is thought to have fathered the famed Theseus. A mortal woman named Tyro was married to Cretheus (with whom she had one son, Aeson), but loved Enipeus, a river god. She pursued Enipeus, who refused her advances. One day, Poseidon, filled with lust for Tyro, disguised himself as Enipeus, and from their union were born the heroes Pelias and Neleus, twin boys. Poseidon also had an affair with Alope, his granddaughter through Cercyon, his son and King of Eleusis, begetting the Attic hero Hippothoon. Cercyon had his daughter buried alive but Poseidon turned her into the spring, Alope, near Eleusis. Poseidon rescued Amymone from a lecherous satyr and then fathered a child, Nauplius, by her. After having raped Caeneus, Poseidon fulfilled her request and changed her into a male warrior. A mortal woman named Cleito once lived on an isolated island; Poseidon fell in love with the human mortal and created a dwelling sanctuary at the top of a hill near the middle of the island and surrounded the dwelling with rings of water and land to protect her. She gave birth to five sets of twin boys; the firstborn, Atlas, became the first ruler of Atlantis. Not all of Poseidon's children were human. In an archaic myth, Poseidon once pursued Demeter. She spurned his advances, turning herself into a mare so that she could hide in a herd of horses; he saw through the deception and became a stallion and captured her. Their child was a horse, Arion, which was capable of human speech. Poseidon also raped Medusa on the floor of a temple to Athena. Medusa was then changed into a monster by Athena. When she was later beheaded by the hero Perseus, Chrysaor and Pegasus emerged from her neck. His other children include Polyphemus (the Cyclops) and, finally, Alebion and Bergion and Otos and Ephialtae (the giants). The philosopher Plato was held by his fellow ancient Greeks to have traced his descent to the sea-God Poseidon through his father Ariston and his mythic predecessors the demigod kings Codrus and Melanthus. Male lovers included Nerites, Pelops and Patroclus. <div style=display:inline-table> {| class="wikitable sortable" |+Offspring and mothers, Table 1 ! scope="col" style="width: 230pt;" | Offspring ! scope="col" style="width: 130pt;" | Mother |- |Triton, Benthesicyme, Rhodos |Amphitrite |- |Antaeus, Charybdis, Laistryon |Gaea |- |Despoina, Arion |Demeter |- |Rhodos, Herophile |Aphrodite |- |Pegasus, Chrysaor |Medusa |- |Ergiscus |Aba |- |Aethusa, Hyrieus, Hyperenor, Hyperes.

He was associated with dolphins and three-pronged fish spears (tridents). He lived in a palace on the ocean floor, made of coral and gems. In the Iliad Poseidon favors the Greeks, and on several occasion takes an active part in the battle against the Trojan forces. However, in Book XX he rescues Aeneas after the Trojan prince is laid low by Achilles. In the Odyssey, Poseidon is notable for his hatred of Odysseus who blinded the god's son, the Cyclops Polyphemus. The enmity of Poseidon prevents Odysseus's return home to Ithaca for many years. Odysseus is even told, notwithstanding his ultimate safe return, that to placate the wrath of Poseidon will require one more voyage on his part. In the Aeneid, Neptune is still resentful of the wandering Trojans, but is not as vindictive as Juno, and in Book I he rescues the Trojan fleet from the goddess's attempts to wreck it, although his primary motivation for doing this is his annoyance at Juno's having intruded into his domain.

and autogamous (self-fertilization) gamodemes. World human population According to the United States Census Bureau the world's population was about 7.55 billion in 2019 and that the 7 billion number was surpassed on 12 March 2012. According to a separate estimate by the United Nations, Earth's population exceeded seven billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA. According to papers published by the United States Census Bureau, the world population hit 6.5 billion on 24 February 2006. The United Nations Population Fund designated 12 October 1999 as the approximate day on which world population reached 6 billion. This was about 12 years after the world population reached 5 billion in 1987, and six years after the world population reached 5.5 billion in 1993. The population of countries such as Nigeria is not even known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 billion people have probably been born in the last 2000 years. Predicted growth and decline Population growth increased significantly as the Industrial Revolution gathered pace from 1700 onwards. The last 50 years have seen a yet more rapid increase in the rate of population growth due to medical advances and substantial increases in agricultural productivity, particularly beginning in the 1960s, made by the Green Revolution. In 2017 the United Nations Population Division projected that the world's population will reach about 9.8 billion in 2050 and 11.2 billion in 2100. In the future, the world's population is expected to peak, after which it will decline due to economic reasons, health concerns, land exhaustion and environmental hazards. According to one report, it is very likely that the world's population will stop growing before the end of the 21st century. Further, there is some likelihood that population will actually decline before 2100. Population has already declined in the last decade or two in Eastern Europe, the Baltics and in the Commonwealth of Independent States. The population pattern of less-developed regions of the world in recent years has been marked by gradually declining birth rates. These followed an earlier sharp reduction in death rates. This transition from high birth and death rates to low birth and death rates is often referred to as the demographic transition. Population planning Human population planning is the practice of altering the rate of growth of a human population. Historically, human population control has been implemented with the goal of limiting the rate of population growth. In the period from the 1950s to the 1980s, concerns | developed which deliberately utilize the effects of dispersion (such as line breeding, pure-line breeding, backcrossing). It can be shown that dispersion-assisted selection leads to the greatest genetic advance (ΔG=change in the phenotypic mean), and is much more powerful than selection acting without attendant dispersion. This is so for both allogamous (random fertilization) and autogamous (self-fertilization) gamodemes.

the main factor of the decision. When a dog is first taught to sit, it is given a biscuit. This is repeated until, finally, the dog sits without requiring a biscuit. Psychological egoists could claim that such actions which do not 'directly' result in positivity, or reward, are not dissimilar from the actions of the dog. In this case, the action (sitting on command) will have become a force of habit, and breaking such a habit would result in mental discomfort. This basic theory of conditioning behaviour, applied to other seemingly ineffective positive actions, can be used to explain moral responses that are instantaneous and instinctive such as the soldier jumping on the grenade. Circularity Psychological egoism has been accused of being circular: "If a person willingly performs an act, that means he derives personal enjoyment from it; therefore, people only perform acts that give them personal enjoyment." In particular, seemingly altruistic acts must be performed because people derive enjoyment from them and are therefore, in reality, egoistic. This statement is circular because its conclusion is identical to its hypothesis: it assumes that people only perform acts that give them personal enjoyment, and concludes that people only perform acts that give them personal enjoyment. This objection was tendered by William Hazlitt and Thomas Macaulay in the 19th century, and has been restated many times since. An earlier version of the same objection was made by Joseph Butler in 1726. Joel Feinberg, in his 1958 paper "Psychological Egoism", embraces a similar critique by drawing attention to the infinite regress of psychological egoism. He expounds it in the following cross-examination: "All men desire only satisfaction." "Satisfaction of what?" "Satisfaction of their desires." "Their desires for what?" "Their desires for satisfaction." "Satisfaction of what?" "Their desires." "For what?" "For satisfaction"—etc., ad infinitum. Evolutionary argument In their 1998 book, Unto Others, Sober and Wilson detailed an evolutionary argument based on the likelihood for egoism to evolve under the pressures of natural selection. Specifically, they focus on the human behavior of parental care. To set up their argument, they propose two potential psychological mechanisms for this. The hedonistic mechanism is based on a parent's ultimate desire for pleasure or the avoidance of pain and a belief that caring for its offspring will be instrumental to that. The altruistic mechanism is based on an altruistic ultimate desire to care for its offspring. Sober and Wilson argue that when evaluating the likelihood of a given trait to evolve, three factors must be considered: availability, reliability and energetic efficiency. The genes for a given trait must first be available in the gene pool for selection. The trait must then reliably produce an increase in fitness for the organism. The trait must also operate with energetic efficiency to not limit the fitness of the organism. Sober and Wilson argue that there is neither reason to suppose that an altruistic mechanism should be any less available than a hedonistic one nor reason to suppose that the content of thoughts and desires (hedonistic vs. altruistic) should impact energetic efficiency. As availability and energetic efficiency are taken to be equivalent for both mechanisms it follows that the more reliable mechanism will then be the more likely mechanism. For the hedonistic mechanism to produce the behavior of caring for offspring, the parent must believe that the caring behavior will produce pleasure or avoidance of pain for the parent. Sober and Wilson argue that the belief also must be true and constantly reinforced, or it would not be likely enough to persist. If the belief fails then the behavior is not produced. The altruistic mechanism does not rely on belief; therefore, they argue that it would be less likely to fail than the alternative, i.e. more reliable. Equivocation In philosopher Derek Parfit's 2011 book On What Matters, Volume 1, Parfit presents an argument against psychological egoism that centers around an apparent equivocation between different senses of the word "want": The word desire often refers to our sensual desires or appetites, or to our being attracted to something, by finding the thought of it appealing. I shall use ‘desire’ in a wider sense, which refers to any state of being motivated, or of wanting something to happen and being to some degree disposed to make it happen, if we can. The word want already has both these senses. Some people think: Whenever people act voluntarily, they are doing what they want to do. Doing what we want is selfish. So everyone always acts selfishly. This argument for Psychological Egoism fails, because it uses the word want first in the wide sense and then in the narrow sense. If I voluntarily gave up my life to save the lives of several strangers, my act would not be selfish, though I would be doing what in the wide sense I wanted to do.

"Egoism as a Theory of Human Motives," in his Broad's Critical Essays in Moral Philosophy, | the dog sits without requiring a biscuit. Psychological egoists could claim that such actions which do not 'directly' result in positivity, or reward, are not dissimilar from the actions of the dog. In this case, the action (sitting on command) will have become a force of habit, and breaking such a habit would result in mental discomfort. This basic theory of conditioning behaviour, applied to other seemingly ineffective positive actions, can be used to explain moral responses that are instantaneous and instinctive such as the soldier jumping on the grenade. Circularity Psychological egoism has been accused of being circular: "If a person willingly performs an act, that means he derives personal enjoyment from it; therefore, people only perform acts that give them personal enjoyment." In particular, seemingly altruistic acts must be performed because people derive enjoyment from them and are therefore, in reality, egoistic. This statement is circular because its conclusion is identical to its hypothesis: it assumes that people only perform acts that give them personal enjoyment, and concludes that people only perform acts that give them personal enjoyment. This objection was tendered by William Hazlitt and Thomas Macaulay in the 19th century, and has been restated many times since. An earlier version of the same objection was made by Joseph Butler in 1726. Joel Feinberg, in his 1958 paper "Psychological Egoism", embraces a similar critique by drawing attention to the infinite regress of psychological egoism. He expounds it in the following cross-examination: "All men desire only satisfaction." "Satisfaction of what?" "Satisfaction of their desires." "Their desires for what?" "Their desires for satisfaction." "Satisfaction of what?" "Their desires." "For what?" "For satisfaction"—etc., ad infinitum. Evolutionary argument In their 1998 book, Unto Others, Sober and Wilson detailed an evolutionary argument based on the likelihood for egoism to evolve under the pressures of natural selection. Specifically, they focus on the human behavior of parental care. To set up their argument, they propose two potential psychological mechanisms for this. The hedonistic mechanism is based on a parent's ultimate desire for pleasure or the avoidance of pain and a belief that caring for its offspring will be instrumental to that. The altruistic mechanism is based on an altruistic ultimate desire to care for its offspring. Sober and Wilson argue that when evaluating the likelihood of a given trait to evolve, three factors must be considered: availability, reliability and energetic efficiency. The genes for a given trait must first be available in the gene pool for selection. The trait must then reliably produce an increase in fitness for the organism. The trait must also operate with energetic efficiency to not limit the fitness of the organism. Sober and Wilson argue that there is neither reason to suppose that an altruistic mechanism should be any less available than a hedonistic one nor reason to suppose that the content of thoughts and desires (hedonistic vs. altruistic) should impact energetic efficiency. As availability and energetic efficiency are taken to be equivalent for both mechanisms it follows that the more reliable mechanism will then be the more likely mechanism. For the hedonistic mechanism to produce the behavior of caring for offspring, the parent must believe that the caring behavior will produce pleasure or avoidance of pain for the parent. Sober and Wilson argue that the belief also must be true and constantly reinforced, or it would not be likely enough to persist. If the belief fails then the behavior is not produced. The altruistic mechanism does not rely on belief; therefore, they argue that it would be less likely to fail than the alternative, i.e. more reliable. Equivocation In philosopher Derek Parfit's 2011 book On What Matters, Volume 1, Parfit presents an argument against psychological egoism that centers around an apparent equivocation between different senses of the word "want": The word desire often refers to our sensual desires or appetites, or to our being attracted to something, by finding the thought of it appealing. I shall use ‘desire’ in a wider sense, which refers to any state of being motivated, or of wanting something to happen and being to some degree disposed to make it happen, if we can. The word want already has both these senses. Some people think: Whenever people act voluntarily, they are doing what they want to do. Doing what we want is selfish. So everyone always acts selfishly. This argument for Psychological Egoism fails, because it uses the word want first in the wide sense and then in the narrow sense. If I voluntarily gave up my life to save the lives of several strangers, my act would not be selfish, though I would be doing what in the wide sense I wanted to do.

persuasion, Socrates says reason and wisdom should govern. As Socrates puts it: "Until philosophers rule as kings or those who are now called kings and leading men genuinely and adequately philosophize, that is, until political power and philosophy entirely coincide, while the many natures who at present pursue either one exclusively are forcibly prevented from doing so, cities will have no rest from evils,... nor, I think, will the human race." Socrates describes these "philosopher kings" as "those who love the sight of truth" and supports the idea with the analogy of a captain and his ship or a doctor and his medicine. According to him, sailing and health are not things that everyone is qualified to practice by nature. A large part of the Republic then addresses how the educational system should be set up to produce these philosopher kings. In addition, the ideal city is used as an image to illuminate the state of one's soul, or the will, reason, and desires combined in the human body. Socrates is attempting to make an image of a rightly ordered human, and then later goes on to describe the different kinds of humans that can be observed, from tyrants to lovers of money in various kinds of cities. The ideal city is not promoted, but only used to magnify the different kinds of individual humans and the state of their soul. However, the philosopher king image was used by many after Plato to justify their personal political beliefs. The philosophic soul according to Socrates has reason, will, and desires united in virtuous harmony. A philosopher has the moderate love for wisdom and the courage to act according to wisdom. Wisdom is knowledge about the Good or the right relations between all that exists. Wherein it concerns states and rulers, Socrates asks which is better—a bad democracy or a country reigned by a tyrant. He argues that it is better to be ruled by a bad tyrant, than by a bad democracy (since here all the people are now responsible for such actions, rather than one individual committing many bad deeds.) This is emphasised within the Republic as Socrates describes the event of mutiny on board a ship. Socrates suggests the ship's crew to be in line with the democratic rule of many and the captain, although inhibited through ailments, the tyrant. Socrates' description of this event is parallel to that of democracy within the state and the inherent problems that arise. According to Socrates, a state made up of different kinds of souls will, overall, decline from an aristocracy (rule by the best) to a timocracy (rule by the honourable), then to an oligarchy (rule by the few), then to a democracy (rule by the people), and finally to tyranny (rule by one person, rule by a tyrant). Aristocracy in the sense of government (politeia) is advocated in Plato's Republic. This regime is ruled by a philosopher king, and thus is grounded on wisdom and reason. The aristocratic state, and the man whose nature corresponds to it, are the objects of Plato's analyses throughout much of the Republic, as opposed to the other four types of states/men, who are discussed later in his work. In Book VIII, Socrates states in order the other four imperfect societies with a description of the state's structure and individual character. In timocracy, the ruling class is made up primarily of those with a warrior-like character. Oligarchy is made up of a society in which wealth is the criterion of merit and the wealthy are in control. In democracy, the state bears resemblance to ancient Athens with traits such as equality of political opportunity and freedom for the individual to do as he likes. Democracy then degenerates into tyranny from the conflict of rich and poor. It is characterized by an undisciplined society existing in chaos, where the tyrant rises as a popular champion leading to the formation of his private army and the growth of oppression. Art and poetry Several dialogues tackle questions about art, including rhetoric and rhapsody. Socrates says that poetry is inspired by the muses, and is not rational. He speaks approvingly of this, and other forms of divine madness (drunkenness, eroticism, and dreaming) in the Phaedrus, and yet in the Republic wants to outlaw Homer's great poetry, and laughter as well. In Ion, Socrates gives no hint of the disapproval of Homer that he expresses in the Republic. The dialogue Ion suggests that Homer's Iliad functioned in the ancient Greek world as the Bible does today in the modern Christian world: as divinely inspired literature that can provide moral guidance, if only it can be properly interpreted. Rhetoric Scholars often view Plato's philosophy as at odds with rhetoric due to his criticisms of rhetoric in the Gorgias and his ambivalence toward rhetoric expressed in the Phaedrus. But other contemporary researchers contest the idea that Plato despised rhetoric and instead view his dialogues as a dramatization of complex rhetorical principles. Unwritten doctrines For a long time, Plato's unwritten doctrines had been controversial. Many modern books on Plato seem to diminish its importance; nevertheless, the first important witness who mentions its existence is Aristotle, who in his Physics writes: "It is true, indeed, that the account he gives there [i.e. in Timaeus] of the participant is different from what he says in his so-called unwritten teachings ()." The term "" literally means unwritten doctrines or unwritten dogmas and it stands for the most fundamental metaphysical teaching of Plato, which he disclosed only orally, and some say only to his most trusted fellows, and which he may have kept secret from the public. The importance of the unwritten doctrines does not seem to have been seriously questioned before the 19th century. A reason for not revealing it to everyone is partially discussed in Phaedrus where Plato criticizes the written transmission of knowledge as faulty, favouring instead the spoken logos: "he who has knowledge of the just and the good and beautiful ... will not, when in earnest, write them in ink, sowing them through a pen with words, which cannot defend themselves by argument and cannot teach the truth effectually." The same argument is repeated in Plato's Seventh Letter: "every serious man in dealing with really serious subjects carefully avoids writing." In the same letter he writes: "I can certainly declare concerning all these writers who claim to know the subjects that I seriously study ... there does not exist, nor will there ever exist, any treatise of mine dealing therewith." Such secrecy is necessary in order not "to expose them to unseemly and degrading treatment". It is, however, said that Plato once disclosed this knowledge to the public in his lecture On the Good (), in which the Good () is identified with the One (the Unity, ), the fundamental ontological principle. The content of this lecture has been transmitted by several witnesses. Aristoxenus describes the event in the following words: "Each came expecting to learn something about the things that are generally considered good for men, such as wealth, good health, physical strength, and altogether a kind of wonderful happiness. But when the mathematical demonstrations came, including numbers, geometrical figures and astronomy, and finally the statement Good is One seemed to them, I imagine, utterly unexpected and strange; hence some belittled the matter, while others rejected it." Simplicius quotes Alexander of Aphrodisias, who states that "according to Plato, the first principles of everything, including the Forms themselves are One and Indefinite Duality (), which he called Large and Small ()", and Simplicius reports as well that "one might also learn this from Speusippus and Xenocrates and the others who were present at Plato's lecture on the Good". Their account is in full agreement with Aristotle's description of Plato's metaphysical doctrine. In Metaphysics he writes: "Now since the Forms are the causes of everything else, he [i.e. Plato] supposed that their elements are the elements of all things. Accordingly, the material principle is the Great and Small [i.e. the Dyad], and the essence is the One (), since the numbers are derived from the Great and Small by participation in the One". "From this account it is clear that he only employed two causes: that of the essence, and the material cause; for the Forms are the cause of the essence in everything else, and the One is the cause of it in the Forms. He also tells us what the material substrate is of which the Forms are predicated in the case of sensible things, and the One in that of the Forms—that it is this the duality (the Dyad, ), the Great and Small (). Further, he assigned to these two elements respectively the causation of good and of evil". The most important aspect of this interpretation of Plato's metaphysics is the continuity between his teaching and the Neoplatonic interpretation of Plotinus{{efn|Plotinus describes this in the last part of his final Ennead (VI, 9) entitled On the Good, or the One (). Jens Halfwassen states in Der Aufstieg zum Einen'] (2006) that "Plotinus' ontology—which should be called Plotinus' henology—is a rather accurate philosophical renewal and continuation of Plato's unwritten doctrine, i.e. the doctrine rediscovered by Krämer and Gaiser."}} or Ficino which has been considered erroneous by many but may in fact have been directly influenced by oral transmission of Plato's doctrine. A modern scholar who recognized the importance of the unwritten doctrine of Plato was Heinrich Gomperz who described it in his speech during the 7th International Congress of Philosophy in 1930. All the sources related to the have been collected by Konrad Gaiser and published as Testimonia Platonica. These sources have subsequently been interpreted by scholars from the German Tübingen School of interpretation such as Hans Joachim Krämer or Thomas A. Szlezák. Themes of Plato's dialogues Trial of Socrates The trial of Socrates and his death sentence is the central, unifying event of Plato's dialogues. It is relayed in the dialogues Apology, Crito, and Phaedo. Apology is Socrates' defence speech, and Crito and Phaedo take place in prison after the conviction.Apology is among the most frequently read of Plato's works. In the Apology, Socrates tries to dismiss rumours that he is a sophist and defends himself against charges of disbelief in the gods and corruption of the young. Socrates insists that long-standing slander will be the real cause of his demise, and says the legal charges are essentially false. Socrates famously denies being wise, and explains how his life as a philosopher was launched by the Oracle at Delphi. He says that his quest to resolve the riddle of the oracle put him at odds with his fellow man, and that this is the reason he has been mistaken for a menace to the city-state of Athens. In Apology, Socrates is presented as mentioning Plato by name as one of those youths close enough to him to have been corrupted, if he were in fact guilty of corrupting the youth, and questioning why their fathers and brothers did not step forward to testify against him if he was indeed guilty of such a crime. Later, Plato is mentioned along with Crito, Critobolus, and Apollodorus as offering to pay a fine of 30 minas on Socrates' behalf, in lieu of the death penalty proposed by Meletus. In the Phaedo, the title character lists those who were in attendance at the prison on Socrates' last day, explaining Plato's absence by saying, "Plato was ill". The trial in other dialogues If Plato's important dialogues do not refer to Socrates' execution explicitly, they allude to it, or use characters or themes that play a part in it. Five dialogues foreshadow the trial: In the Theaetetus and the Euthyphro Socrates tells people that he is about to face corruption charges.Euthyphro 2a–b In the Meno, one of the men who brings legal charges against Socrates, Anytus, warns him about the trouble he may get into if he does not stop criticizing important people. In the Gorgias, Socrates says that his trial will be like a doctor prosecuted by a cook who asks a jury of children to choose between the doctor's bitter medicine and the cook's tasty treats. In the Republic, Socrates explains why an enlightened man (presumably himself) will stumble in a courtroom situation. Plato's support of aristocracy and distrust of democracy is also taken to be partly rooted in a democracy having killed Socrates. In the Protagoras, Socrates is a guest at the home of Callias, son of Hipponicus, a man whom Socrates disparages in the Apology as having wasted a great amount of money on sophists' fees. Two other important dialogues, the Symposium and the Phaedrus, are linked to the main storyline by characters. In the Apology, Socrates says Aristophanes slandered him in a comic play, and blames him for causing his bad reputation, and ultimately, his death. In the Symposium, the two of them are drinking together with other friends. The character Phaedrus is linked to the main story line by character (Phaedrus is also a participant in the Symposium and the Protagoras) and by theme (the philosopher as divine emissary, etc.) The Protagoras is also strongly linked to the Symposium by characters: all of the formal speakers at the Symposium (with the exception of Aristophanes) are present at the home of Callias in that dialogue. Charmides and his guardian Critias are present for the discussion in the Protagoras. Examples of characters crossing between dialogues can be further multiplied. The Protagoras contains the largest gathering of Socratic associates. In the dialogues Plato is most celebrated and admired for, Socrates is concerned with human and political virtue, has a distinctive personality, and friends and enemies who "travel" with him from dialogue to dialogue. This is not to say that Socrates is consistent: a man who is his friend in one dialogue may be an adversary or subject of his mockery in another. For example, Socrates praises the wisdom of Euthyphro many times in the Cratylus, but makes him look like a fool in the Euthyphro. He disparages sophists generally, and Prodicus specifically in the Apology, whom he also slyly jabs in the Cratylus for charging the hefty fee of fifty drachmas for a course on language and grammar. However, Socrates tells Theaetetus in his namesake dialogue that he admires Prodicus and has directed many pupils to him. Socrates' ideas are also not consistent within or between or among dialogues. Allegories Mythos and logos are terms that evolved throughout classical Greek history. In the times of Homer and Hesiod (8th century BC) they were essentially synonyms, and contained the meaning of 'tale' or 'history'. Later came historians like Herodotus and Thucydides, as well as philosophers like Heraclitus and Parmenides and other Presocratics who introduced a distinction between both terms; mythos became more a nonverifiable account, and logos a rational account. It may seem that Plato, being a disciple of Socrates and a strong partisan of philosophy based on logos, should have avoided the use of myth-telling. Instead, he made abundant use of it. This fact has produced analytical and interpretative work, in order to clarify the reasons and purposes for that use. Plato, in general, distinguished between three types of myth. First, there were the false myths, like those based on stories of gods subject to passions and sufferings, because reason teaches that God is perfect. Then came the myths based on true reasoning, and therefore also true. Finally, there were those non-verifiable because beyond of human reason, but containing some truth in them. Regarding the subjects of Plato's myths, they are of two types, those dealing with the origin of the universe, and those about morals and the origin and fate of the soul. It is generally agreed that the main purpose for Plato in using myths was didactic. He considered that only a few people were capable or interested in following a reasoned philosophical discourse, but men in general are attracted by stories and tales. Consequently, then, he used the myth to convey the conclusions of the philosophical reasoning. Some of Plato's myths were based in traditional ones, others were modifications of them, and finally, he also invented altogether new myths. Notable examples include the story of Atlantis, the Myth of Er, and the Allegory of the Cave. The Cave The theory of Forms is most famously captured in his Allegory of the Cave, and more explicitly in his analogy of the sun and the divided line. The Allegory of the Cave is a paradoxical analogy wherein Socrates argues that the invisible world is the most intelligible (noeton) and that the visible world ((h)oraton) is the least knowable, and the most obscure. Socrates says in the Republic that people who take the sun-lit world of the senses to be good and real are living pitifully in a den of evil and ignorance. Socrates admits that few climb out of the den, or cave of ignorance, and those who do, not only have a terrible struggle to attain the heights, but when they go back down for a visit or to help other people up, they find themselves objects of scorn and ridicule. According to Socrates, physical objects and physical events are "shadows" of their ideal or perfect forms, and exist only to the extent that they instantiate the perfect versions of themselves. Just as shadows are temporary, inconsequential epiphenomena produced by physical objects, physical objects are themselves fleeting phenomena caused by more substantial causes, the ideals of which they are mere instances. For example, Socrates thinks that perfect justice exists (although it is not clear where) and his own trial would be a cheap copy of it. The Allegory of the Cave is intimately connected to his political ideology, that only people who have climbed out of the cave and cast their eyes on a vision of goodness are fit to rule. Socrates claims that the enlightened men of society must be forced from their divine contemplation and be compelled to run the city according to their lofty insights. Thus is born the idea of the "philosopher-king", the wise person who accepts the power thrust upon him by the people who are wise enough to choose a good master. This is the main thesis of Socrates in the Republic, that the most wisdom the masses can muster is the wise choice of a ruler. Ring of Gyges A ring which could make one invisible, the Ring of Gyges is proposed in the Republic by the character of Glaucon, and considered by the rest of the characters for its ethical consequences, whether an individual possessing it would be most happy abstaining or doing injustice. Chariot He also compares the soul (psyche) to a chariot. In this allegory he introduces a triple soul composed of a charioteer and two horses. The charioteer is a symbol of the intellectual and logical part of the soul (logistikon), and the two horses represent the moral virtues (thymoeides) and passionate instincts (epithymetikon), respectively, to illustrate the conflict between them. Dialectic Socrates employs a dialectic method which proceeds by questioning. The role of dialectic in Plato's thought is contested but there are two main interpretations: a type of reasoning and a method of intuition. Simon Blackburn adopts the first, saying that Plato's dialectic is "the process of eliciting the truth by means of questions aimed at opening out what is already implicitly known, or at exposing the contradictions and muddles of an opponent's position." A similar interpretation has been put forth by Louis Hartz, who compares Plato's dialectic to that of Hegel. According to this view, opposing arguments improve upon each other, and prevailing opinion is shaped by the synthesis of many conflicting ideas over time. Each new idea exposes a flaw in the accepted model, and the epistemological substance of the debate continually approaches the truth. Hartz's is a teleological interpretation at the core, in which philosophers will ultimately exhaust the available body of knowledge and thus reach "the end of history." Karl Popper, on the other hand, claims that dialectic is the art of intuition for "visualising | and was influenced by his ideas. Augustine initially accepted this claim, but later rejected it, arguing in The City of God that "Plato was born a hundred years after Jeremiah prophesied." Later life and death Plato may have travelled in Italy, Sicily, Egypt, and Cyrene. Plato's own statement was that he visited Italy and Sicily at the age of forty and was disgusted by the sensuality of life there. Said to have returned to Athens at the age of forty, Plato founded one of the earliest known organized schools in Western Civilization on a plot of land in the Grove of Hecademus or Academus. This land was named after Academus, an Attic hero in Greek mythology. In historic Greek times it was adorned with oriental plane and olive plantations The Academy was a large enclosure of ground about six stadia (a total of between a kilometer and a half mile) outside of Athens proper. One story is that the name of the comes from the ancient hero, Academus; still another story is that the name came from a supposed former owner of the plot of land, an Athenian citizen whose name was (also) Academus; while yet another account is that it was named after a member of the army of Castor and Pollux, an Arcadian named Echedemus. The operated until it was destroyed by Lucius Cornelius Sulla in 84 BC. Many intellectuals were schooled in the , the most prominent one being Aristotle. Throughout his later life, Plato became entangled with the politics of the city of Syracuse. According to Diogenes Laërtius, Plato initially visited Syracuse while it was under the rule of Dionysius. During this first trip Dionysius's brother-in-law, Dion of Syracuse, became one of Plato's disciples, but the tyrant himself turned against Plato. Plato almost faced death, but he was sold into slavery. Anniceris, a Cyrenaic philosopher, subsequently bought Plato's freedom for twenty minas, and sent him home. After Dionysius's death, according to Plato's Seventh Letter, Dion requested Plato return to Syracuse to tutor Dionysius II and guide him to become a philosopher king. Dionysius II seemed to accept Plato's teachings, but he became suspicious of Dion, his uncle. Dionysius expelled Dion and kept Plato against his will. Eventually Plato left Syracuse. Dion would return to overthrow Dionysius and ruled Syracuse for a short time before being usurped by Calippus, a fellow disciple of Plato. According to Seneca, Plato died at the age of 81 on the same day he was born. The Suda indicates that he lived to 82 years, while Neanthes claims an age of 84. A variety of sources have given accounts of his death. One story, based on a mutilated manuscript, suggests Plato died in his bed, whilst a young Thracian girl played the flute to him. Another tradition suggests Plato died at a wedding feast. The account is based on Diogenes Laërtius's reference to an account by Hermippus, a third-century Alexandrian. According to Tertullian, Plato simply died in his sleep. Plato owned an estate at Iphistiadae, which by will he left to a certain youth named Adeimantus, presumably a younger relative, as Plato had an elder brother or uncle by this name. Influences Pythagoras Although Socrates influenced Plato directly as related in the dialogues, the influence of Pythagoras upon Plato, or in a broader sense, the Pythagoreans, such as Archytas also appears to have been significant. Aristotle claimed that the philosophy of Plato closely followed the teachings of the Pythagoreans, and Cicero repeats this claim: "They say Plato learned all things Pythagorean." It is probable that both were influenced by Orphism, and both believed in metempsychosis, transmigration of the soul. Pythagoras held that all things are number, and the cosmos comes from numerical principles. He introduced the concept of form as distinct from matter, and that the physical world is an imitation of an eternal mathematical world. These ideas were very influential on Heraclitus, Parmenides and Plato. George Karamanolis notes thatNumenius accepted both Pythagoras and Plato as the two authorities one should follow in philosophy, but he regarded Plato's authority as subordinate to that of Pythagoras, whom he considered to be the source of all true philosophy—including Plato's own. For Numenius it is just that Plato wrote so many philosophical works, whereas Pythagoras' views were originally passed on only orally. According to R. M. Hare, this influence consists of three points: The platonic Republic might be related to the idea of "a tightly organized community of like-minded thinkers", like the one established by Pythagoras in Croton. The idea that mathematics and, generally speaking, abstract thinking is a secure basis for philosophical thinking as well as "for substantial theses in science and morals". They shared a "mystical approach to the soul and its place in the material world". Plato and mathematics Plato may have studied under the mathematician Theodorus of Cyrene, and has a dialogue named for and whose central character is the mathematician Theaetetus. While not a mathematician, Plato was considered an accomplished teacher of mathematics. Eudoxus of Cnidus, the greatest mathematician in Classical Greece, who contributed much of what is found in Euclid's Elements, was taught by Archytas and Plato. Plato helped to distinguish between pure and applied mathematics by widening the gap between "arithmetic", now called number theory and "logistic", now called arithmetic. In the dialogue Timaeus Plato associated each of the four classical elements (earth, air, water, and fire) with a regular solid (cube, octahedron, icosahedron, and tetrahedron respectively) due to their shape, the so-called Platonic solids. The fifth regular solid, the dodecahedron, was supposed to be the element which made up the heavens. Heraclitus and Parmenides The two philosophers Heraclitus and Parmenides, following the way initiated by pre-Socratic Greek philosophers such as Pythagoras, depart from mythology and begin the metaphysical tradition that strongly influenced Plato and continues today. The surviving fragments written by Heraclitus suggest the view that all things are continuously changing, or becoming. His image of the river, with ever-changing waters, is well known. According to some ancient traditions such as that of Diogenes Laërtius, Plato received these ideas through Heraclitus' disciple Cratylus, who held the more radical view that continuous change warrants scepticism because we cannot define a thing that does not have a permanent nature. Parmenides adopted an altogether contrary vision, arguing for the idea of changeless Being and the view that change is an illusion. John Palmer notes "Parmenides' distinction among the principal modes of being and his derivation of the attributes that must belong to what must be, simply as such, qualify him to be seen as the founder of metaphysics or ontology as a domain of inquiry distinct from theology." These ideas about change and permanence, or becoming and Being, influenced Plato in formulating his theory of Forms. Plato's most self-critical dialogue is the Parmenides, which features Parmenides and his student Zeno, who, following Parmenides' denial of change, argued forcefully through his paradoxes to deny the existence of motion. Plato's Sophist dialogue includes an Eleatic stranger, a follower of Parmenides, as a foil for his arguments against Parmenides. In the dialogue, Plato distinguishes nouns and verbs, providing some of the earliest treatment of subject and predicate. He also argues that motion and rest both "are", against followers of Parmenides who say rest is but motion is not. Socrates Plato was one of the devoted young followers of Socrates. The precise relationship between Plato and Socrates remains an area of contention among scholars. Plato never speaks in his own voice in his dialogues, and speaks as Socrates in all but the Laws. In the Second Letter, it says, "no writing of Plato exists or ever will exist, but those now said to be his are those of a Socrates become beautiful and new"; if the Letter is Plato's, the final qualification seems to call into question the dialogues' historical fidelity. In any case, Xenophon's Memorabilia and Aristophanes's The Clouds seem to present a somewhat different portrait of Socrates from the one Plato paints. The Socratic problem asks how to reconcile these various accounts. Leo Strauss notes that Socrates' reputation for irony casts doubt on whether Plato's Socrates is expressing sincere beliefs. Aristotle attributes a different doctrine with respect to Forms to Plato and Socrates. Aristotle suggests that Socrates' idea of forms can be discovered through investigation of the natural world, unlike Plato's Forms that exist beyond and outside the ordinary range of human understanding. In the dialogues of Plato though, Socrates sometimes seems to support a mystical side, discussing reincarnation and the mystery religions, this is generally attributed to Plato. Regardless, this view of Socrates cannot be dismissed out of hand, as we cannot be sure of the differences between the views of Plato and Socrates. In the Meno Plato refers to the Eleusinian Mysteries, telling Meno he would understand Socrates's answers better if he could stay for the initiations next week. It is possible that Plato and Socrates took part in the Eleusinian Mysteries. Philosophy Metaphysics In Plato's dialogues, Socrates and his company of disputants had something to say on many subjects, including several aspects of metaphysics. These include religion and science, human nature, love, and sexuality. More than one dialogue contrasts perception and reality, nature and custom, and body and soul. Francis Cornford referred to the "twin pillars of Platonism" as being the theory of Forms on the one hand, and, on the other hand, the doctrine of immortality of the soul. The Forms "Platonism" and its theory of Forms (or theory of Ideas) denies the reality of the material world, considering it only an image or copy of the real world. The theory of Forms is first introduced in the Phaedo dialogue (also known as On the Soul), wherein Socrates refutes the pluralism of the likes of Anaxagoras, then the most popular response to Heraclitus and Parmenides, while giving the "Opposites Argument" in support of the Forms. According to this theory of Forms, there are at least two worlds: the apparent world of concrete objects, grasped by the senses, which constantly changes, and an unchanging and unseen world of Forms or abstract objects, grasped by pure reason (), which ground what is apparent. It can also be said there are three worlds, with the apparent world consisting of both the world of material objects and of mental images, with the "third realm" consisting of the Forms. Thus, though there is the term "Platonic idealism", this refers to Platonic Ideas or the Forms, and not to some platonic kind of idealism, an 18th-century view which sees matter as unreal in favour of mind. For Plato, though grasped by the mind, only the Forms are truly real. Plato's Forms thus represent types of things, as well as properties, patterns, and relations, to which we refer as objects. Just as individual tables, chairs, and cars refer to objects in this world, 'tableness', 'chairness', and 'carness', as well as e. g. justice, truth, and beauty refer to objects in another world. One of Plato's most cited examples for the Forms were the truths of geometry, such as the Pythagorean theorem. In other words, the Forms are universals given as a solution to the problem of universals, or the problem of "the One and the Many", e. g. how one predicate "red" can apply to many red objects. For Plato, this is because there is one abstract object or Form of red, redness itself, in which the several red things "participate". As Plato's solution is that universals are Forms and that Forms are real if anything is, Plato's philosophy is unambiguously called Platonic realism. According to Aristotle, Plato's best-known argument in support of the Forms was the "one over many" argument. Aside from being immutable, timeless, changeless, and one over many, the Forms also provide definitions and the standard against which all instances are measured. In the dialogues Socrates regularly asks for the meaning – in the sense of intensional definitions – of a general term (e. g. justice, truth, beauty), and criticizes those who instead give him particular, extensional examples, rather than the quality shared by all examples. There is thus a world of perfect, eternal, and changeless meanings of predicates, the Forms, existing in the realm of Being outside of space and time; and the imperfect sensible world of becoming, subjects somehow in a state between being and nothing, that partakes of the qualities of the Forms, and is its instantiation. The soul For Plato, as was characteristic of ancient Greek philosophy, the soul was that which gave life. See this brief exchange from the Phaedo: "What is it that, when present in a body, makes it living? — A soul." Plato advocates a belief in the immortality of the soul, and several dialogues end with long speeches imagining the afterlife. In the Timaeus, Socrates locates the parts of the soul within the human body: Reason is located in the head, spirit in the top third of the torso, and the appetite in the middle third of the torso, down to the navel. Epistemology Plato also discusses several aspects of epistemology. More than one dialogue contrasts knowledge (episteme) and opinion (doxa). Plato's epistemology involves Socrates (and other characters, such as Timaeus) arguing that knowledge is not empirical, and that it comes from divine insight. The Forms are also responsible for both knowledge or certainty, and are grasped by pure reason. In several dialogues, Socrates inverts the common man's intuition about what is knowable and what is real. Reality is unavailable to those who use their senses. Socrates says that he who sees with his eyes is blind. While most people take the objects of their senses to be real if anything is, Socrates is contemptuous of people who think that something has to be graspable in the hands to be real. In the Theaetetus, he says such people are eu amousoi (εὖ ἄμουσοι), an expression that means literally, "happily without the muses". In other words, such people are willingly ignorant, living without divine inspiration and access to higher insights about reality. In Plato's dialogues, Socrates always insists on his ignorance and humility, that he knows nothing, so-called "Socratic irony." Several dialogues refute a series of viewpoints, but offer no positive position, thus ending in aporia. Recollection In several of Plato's dialogues, Socrates promulgates the idea that knowledge is a matter of recollection of the state before one is born, and not of observation or study. Keeping with the theme of admitting his own ignorance, Socrates regularly complains of his forgetfulness. In the Meno, Socrates uses a geometrical example to expound Plato's view that knowledge in this latter sense is acquired by recollection. Socrates elicits a fact concerning a geometrical construction from a slave boy, who could not have otherwise known the fact (due to the slave boy's lack of education). The knowledge must be present, Socrates concludes, in an eternal, non-experiential form. In other dialogues, the Sophist, Statesman, Republic, and the Parmenides, Plato himself associates knowledge with the apprehension of unchanging Forms and their relationships to one another (which he calls "expertise" in Dialectic), including through the processes of collection and division. More explicitly, Plato himself argues in the Timaeus that knowledge is always proportionate to the realm from which it is gained. In other words, if one derives one's account of something experientially, because the world of sense is in flux, the views therein attained will be mere opinions. And opinions are characterized by a lack of necessity and stability. On the other hand, if one derives one's account of something by way of the non-sensible forms, because these forms are unchanging, so too is the account derived from them. That apprehension of forms is required for knowledge may be taken to cohere with Plato's theory in the Theaetetus and Meno. Indeed, the apprehension of Forms may be at the base of the "account" required for justification, in that it offers foundational knowledge which itself needs no account, thereby avoiding an infinite regression. Justified true belief Many have interpreted Plato as stating — even having been the first to write — that knowledge is justified true belief, an influential view that informed future developments in epistemology. This interpretation is partly based on a reading of the Theaetetus wherein Plato argues that knowledge is distinguished from mere true belief by the knower having an "account" of the object of their true belief. And this theory may again be seen in the Meno, where it is suggested that true belief can be raised to the level of knowledge if it is bound with an account as to the question of "why" the object of the true belief is so. Many years later, Edmund Gettier famously demonstrated the problems of the justified true belief account of knowledge. That the modern theory of justified true belief as knowledge, which Gettier addresses, is equivalent to Plato's is accepted by some scholars but rejected by others. Plato himself also identified problems with the justified true belief definition in the Theaetetus, concluding that justification (or an "account") would require knowledge of difference, meaning that the definition of knowledge is circular. Ethics Several dialogues discuss ethics including virtue and vice, pleasure and pain, crime and punishment, and justice and medicine. Plato views "The Good" as the supreme Form, somehow existing even "beyond being". Socrates propounded a moral intellectualism which claimed nobody does bad on purpose, and to know what is good results in doing what is good; that knowledge is virtue. In the Protagoras dialogue it is argued that virtue is innate and cannot be learned. Socrates presents the famous Euthyphro dilemma in the dialogue of the same name: "Is the pious (τὸ ὅσιον) loved by the gods because it is pious, or is it pious because it is loved by the gods?" (10a) Justice As above, in the Republic, Plato asks the question, “What is justice?” By means of the Greek term dikaiosune – a term for “justice” that captures both individual justice and the justice that informs societies, Plato is able not only to inform metaphysics, but also ethics and politics with the question: “What is the basis of moral and social obligation?” Plato's well-known answer rests upon the fundamental responsibility to seek wisdom, wisdom which leads to an understanding of the Form of the Good. Plato further argues that such understanding of Forms produces and ensures the good communal life when ideally structured under a philosopher king in a society with three classes (philosopher kings, guardians, and workers) that neatly mirror his triadic view of the individual soul (reason, spirit, and appetite). In this manner, justice is obtained when knowledge of how to fulfill one's moral and political function in society is put into practice. Politics The dialogues also discuss politics. Some of Plato's most famous doctrines are contained in the Republic as well as in the Laws and the Statesman. Because these opinions are not spoken directly by Plato and vary between dialogues, they cannot be straightforwardly assumed as representing Plato's own views. Socrates asserts that societies have a tripartite class structure corresponding to the appetite/spirit/reason structure of the individual soul. The appetite/spirit/reason are analogous to the castes of society. Productive (Workers) – the labourers, carpenters, plumbers, masons, merchants, farmers, ranchers, etc. These correspond to the "appetite" part of the soul. Protective (Warriors or Guardians) – those who are adventurous, strong and brave; in the armed forces. These correspond to the "spirit" part of the soul. Governing (Rulers or Philosopher Kings) – those who are intelligent, rational, self-controlled, in love with wisdom, well suited to make decisions for the community. These correspond to the "reason" part of the soul and are very few. According to this model, the principles of Athenian democracy (as it existed in his day) are rejected as only a few are fit to rule. Instead of rhetoric and persuasion, Socrates says reason and wisdom should govern. As Socrates puts it: "Until philosophers rule as kings or those who are now called kings and leading men genuinely and adequately philosophize, that is, until political power and philosophy entirely coincide, while the many natures who at present pursue either one exclusively are forcibly prevented from doing so, cities will have no rest from evils,... nor, I think, will the human race." Socrates describes these "philosopher kings" as "those who love the sight of truth" and supports the idea with the analogy of a captain and his ship or a doctor and his medicine. According to him, sailing and health are not things that everyone is qualified to practice by nature. A large part of the Republic then addresses how the educational system should be set up to produce these philosopher kings. In addition, the ideal city is used as an image to illuminate the state of one's soul, or the will, reason, and desires combined in the human body. Socrates is attempting to make an image of a rightly ordered human, and then later goes on to describe the different kinds of humans that can be observed, from tyrants to lovers of money in various kinds of cities. The ideal city is not promoted, but only used to magnify the different kinds of individual humans and the state of their soul. However, the philosopher king image was used by many after Plato to justify their personal political beliefs. The philosophic soul according to Socrates has reason, will, and desires united in virtuous harmony. A philosopher has the moderate love for wisdom and the courage to act according to wisdom. Wisdom is knowledge about the Good or the right relations between all that exists. Wherein it concerns states and rulers, Socrates asks which is better—a bad democracy or a country reigned by a tyrant. He argues that it is better to be ruled by a bad tyrant, than by a bad democracy (since here all the people are now responsible for such actions, rather than one individual committing many bad deeds.) This is emphasised within the Republic as Socrates describes the event of mutiny on board a ship. Socrates suggests the ship's crew to be in line with the democratic rule of many and the captain, although inhibited through ailments, the tyrant. Socrates' description of this event is parallel to that of democracy within the state and the inherent problems that arise. According to Socrates, a state made up of different kinds of souls will, overall, decline from an aristocracy (rule by the best) to a timocracy (rule by the honourable), then to an oligarchy (rule by the few), then to a democracy (rule by the people), and finally to tyranny (rule by one person, rule by a tyrant). Aristocracy in the sense of government (politeia) is advocated in Plato's Republic. This regime is ruled by a philosopher king, and thus is grounded on wisdom and reason. The aristocratic state, and the man whose nature corresponds to it, are the objects of Plato's analyses throughout much of the Republic, as opposed to the other four types of states/men, who are discussed later in his work. In Book VIII, Socrates states in order the other four imperfect societies with a description of the state's structure and individual character. In timocracy, the ruling class is made up primarily of those with a warrior-like character. Oligarchy is made up of a society in which wealth is the criterion of merit and the wealthy are in control. In democracy, the state bears resemblance to ancient Athens with traits such as equality of political opportunity and freedom for the individual to do as he likes. Democracy then degenerates into tyranny from the conflict of rich and poor. It is characterized by an undisciplined society existing in chaos, where the tyrant rises as a popular champion leading to the formation of his private army and the growth of oppression. Art and poetry Several dialogues tackle questions about art, including rhetoric and rhapsody. Socrates says that poetry is inspired by the muses, and is not rational. He speaks approvingly of this, and other forms of divine madness (drunkenness, eroticism, and dreaming) in the Phaedrus, and yet in the Republic wants to outlaw Homer's great poetry, and laughter as well. In Ion, Socrates gives no hint of the disapproval of Homer that he expresses in the Republic. The dialogue Ion suggests that Homer's Iliad functioned in the ancient Greek world as the Bible does today in the modern Christian world: as divinely inspired literature that can provide moral guidance, if only it can be properly interpreted. Rhetoric Scholars often view Plato's philosophy as at odds with rhetoric due to his criticisms of rhetoric in the Gorgias and his ambivalence toward rhetoric expressed in the Phaedrus. But other contemporary researchers contest the idea that Plato despised rhetoric and instead view his dialogues as a dramatization of complex rhetorical principles. Unwritten doctrines For a long time, Plato's unwritten doctrines had been controversial. Many modern books on Plato seem to diminish its importance; nevertheless, the first important witness who mentions its existence is Aristotle, who in his Physics writes: "It is true, indeed, that the account he gives there [i.e. in Timaeus] of the participant is different from what he says in his so-called unwritten teachings ()." The term "" literally means unwritten doctrines or unwritten dogmas and it stands for the most fundamental metaphysical teaching of Plato, which he disclosed only orally, and some say only to his most trusted fellows, and which he may have kept secret from the public. The importance of the unwritten doctrines does not seem to have been seriously questioned before the 19th century. A reason for not revealing it to everyone is partially discussed in Phaedrus where Plato criticizes the written transmission of knowledge as faulty, favouring instead the spoken logos: "he who has knowledge of the just and the good and beautiful ... will not, when in earnest, write them in ink, sowing them through a pen with words, which cannot defend themselves by argument and cannot teach the truth effectually." The same argument is repeated in Plato's Seventh Letter: "every serious man in dealing with really serious subjects carefully avoids writing." In the same letter he writes: "I can certainly declare concerning all these writers who claim to know the subjects that I seriously study ... there does not exist, nor will there ever exist, any treatise of mine dealing therewith." Such secrecy is necessary in order not "to expose them to unseemly and degrading treatment". It is, however, said that Plato once disclosed this knowledge to the public in his lecture On the Good (), in which the Good () is identified with the One (the Unity, ), the fundamental ontological principle. The content of this lecture has been transmitted by several witnesses. Aristoxenus describes the event in the following words: "Each came expecting to learn something about the things that are generally considered good for men, such as wealth, good health, physical strength, and altogether a kind of wonderful happiness. But when the mathematical demonstrations came, including numbers, geometrical figures and astronomy, and finally the statement Good is One seemed to them, I imagine, utterly unexpected and strange; hence some belittled the matter, while others rejected it." Simplicius quotes Alexander of Aphrodisias, who states that "according to Plato, the first principles of everything, including the Forms themselves are One and Indefinite Duality (), which he called Large and Small ()", and Simplicius reports as well that "one might also learn this from Speusippus and Xenocrates and the others who were present at Plato's lecture on the Good". Their account is in full agreement with Aristotle's description of Plato's metaphysical doctrine. In Metaphysics he writes: "Now since the Forms are the causes of everything else, he [i.e. Plato] supposed that their elements are the elements of all things. Accordingly, the material principle is the Great and Small [i.e. the Dyad], and the essence is the One (), since the numbers are derived from the Great and Small by participation in the One". "From this account it is clear that he only employed two causes: that of the essence, and the material cause; for the Forms are the cause of the essence in everything else, and the One is the cause of it in the Forms. He also tells us what the material substrate is of which the Forms are predicated in the case of sensible things, and the One in that of the Forms—that it is this the duality (the Dyad, ), the Great and Small (). Further, he assigned to these two elements respectively the causation of good and of evil". The most important aspect of this interpretation of Plato's metaphysics is the continuity between his teaching and the Neoplatonic interpretation of Plotinus{{efn|Plotinus describes this in the last part of his final Ennead (VI, 9) entitled On the Good, or the One (). Jens Halfwassen states in Der Aufstieg zum Einen'] (2006) that "Plotinus' ontology—which should be called Plotinus' henology—is a rather accurate philosophical renewal and continuation of Plato's unwritten doctrine, i.e. the doctrine rediscovered by Krämer and Gaiser."}} or Ficino which has been considered erroneous by many but may in fact have been directly influenced by oral transmission of Plato's doctrine. A modern scholar who recognized the importance of the unwritten doctrine of Plato was Heinrich Gomperz who described it in his speech during the 7th International Congress of Philosophy in 1930. All the sources related to the have been collected by Konrad Gaiser and published as Testimonia Platonica. These sources have subsequently been interpreted by scholars from the German Tübingen School of interpretation such as Hans Joachim Krämer or Thomas A. Szlezák. Themes of Plato's dialogues Trial of Socrates The trial of Socrates and his death sentence is the central, unifying event |
drawing a card from a standard deck of fifty-two playing cards, one possibility for the sample space could be the various ranks (Ace through King), while another could be the suits (clubs, diamonds, hearts, or spades). A more complete description of outcomes, however, could specify both the denomination and the suit, and a sample space describing each individual card can be constructed as the Cartesian product of the two sample spaces noted above (this space would contain fifty-two equally likely outcomes). Still other sample spaces are possible, such as right-side up or upside down, if some cards have been flipped when shuffling. Equally likely outcomes Some treatments of probability assume that the various outcomes of an experiment are always defined so as to be equally likely. For any sample space with equally likely outcomes, each outcome is assigned the probability . However, there are experiments that are not easily described by a sample space of equally likely outcomes—for example, if one were to toss a thumb tack many times and observe whether it landed with its point upward or downward, there is no physical symmetry to suggest that the two outcomes should be equally likely. Though most random phenomena do not have equally likely outcomes, it can be helpful to define a sample space in such a way that outcomes are at least approximately equally likely, since this condition significantly simplifies the computation of probabilities for events within the sample space. If each individual outcome occurs with the same probability, then the probability of any event becomes simply: For example, if two fair six-sided dice are thrown to generate two uniformly distributed integers, and , each in the range from 1 to 6, inclusive, the 36 possible ordered pairs of outcomes constitute a sample space of equally likely events. In this case, the above formula applies, such as calculating the probability of a particular sum of the two rolls in an outcome. The probability of the event that the sum is five is , since four of the thirty-six equally likely pairs of outcomes sum to five. If the sample space was the all of the possible sums obtained from rolling two six-sided dice, the above formula can still be applied because the dice rolls are fair, but the number of outcomes in a given event will vary. A sum of two can occur with the outcome , so the probability is . For a sum of seven, the outcomes in the event are , so the probability is . Simple random sample In statistics, inferences are made about characteristics of a population by studying a sample of that population's individuals. In order to arrive at a sample that presents an unbiased estimate of the true characteristics of the population, statisticians often seek to study a simple random sample—that is, a sample in which every individual in the population is equally likely to be included. The result of this is that every possible combination of individuals who could be chosen for the sample has an equal chance to be the sample that is selected (that is, the space of simple random samples of a given size from a given population is composed of equally likely outcomes). Infinitely large sample spaces In an elementary approach to probability, any subset of the sample space | sample space by the labels S, Ω, or U (for "universal set"). The elements of a sample space may be numbers, words, letters, or symbols. They can also be finite, countably infinite, or uncountably infinite. A subset of the sample space is an event, denoted by . If the outcome of an experiment is included in , then event has occurred. For example, if the experiment is tossing a single coin, the sample space is the set , where the outcome means that the coin was heads and the outcome means that the coin was tails. The possible events are and . For tossing two coins, the sample space is , where the outcome is if both coins are heads, if the first coin is heads and the second is tails, if the first coin is tails and the second is heads, and if both coins are tails. For tossing a single six-sided die, where the result of interest is the number of pips facing up, the sample space is . A well-defined, non-empty sample space is one of three components in a probabilistic model (a probability space). The other two basic elements are: a well-defined set of possible events (an event space), which is typically the power set of if is discrete or a σ-algebra on if it is continuous, and a probability assigned to each event (a probability measure function). A sample space can be represented visually by a rectangle, with the outcomes of the sample space denoted by points within the rectangle. The events may be represented by ovals, where the points enclosed within the oval make up the event. Conditions of a sample space A set with outcomes (i.e. ) must meet some conditions in order to be a sample |
do not determine a continuous probability distribution. Probability of an elementary event Elementary events may occur with probabilities that are between zero and one (inclusively). In a discrete probability distribution whose sample space is finite, each elementary event is assigned a particular probability. In contrast, in a continuous distribution, individual elementary events must all have a probability of zero because there are infinitely many of them— then non-zero probabilities can only be assigned to non-elementary events. Some "mixed" distributions contain both stretches of continuous elementary events and some discrete elementary events; the discrete elementary events in such distributions | event or sample point, is an event which contains only a single outcome in the sample space. Using set theory terminology, an elementary event is a singleton. Elementary events and their corresponding outcomes are often written interchangeably for simplicity, as such an event corresponding to precisely one outcome. The following are examples of elementary events: All sets where if objects are being counted and the sample space is (the natural numbers). if a coin is tossed twice. H stands for heads and T for tails. All sets where is a |
a set of outcomes of an experiment (a subset of the sample space) to which a probability is assigned. A single outcome may be an element of many different events, and different events in an experiment are usually not equally likely, since they may include very different groups of outcomes. An event consisting of only a single outcome is called an or an ; that is, it is a singleton set. An event is said to if contains the outcome of the experiment (or trial) (that is, if ). The probability (with respect to some probability measure) that an event occurs is the probability that contains the outcome of an experiment (that is, it is the probability that ). An event defines a complementary event, namely the complementary set (the event occurring), and together these define a Bernoulli trial: did the event occur or not? Typically, when the sample space is finite, any subset of the sample space is an event (that is, all elements of the power set of the sample space are defined as events). However, this approach does not work well in cases where the sample space is uncountably infinite. | a single outcome is called an or an ; that is, it is a singleton set.

A simple example If we assemble a deck of 52 playing cards with no jokers, and draw a single card from the deck, then the sample space is a 52-element set, as each card is a possible outcome. An event, however, is any subset of the sample space, including any singleton set (an elementary event), the |

Examples are: "every" = "eryevay" "another" = "otheranay" "under" = "erunday" "island" = "andislay" "elegant" = "egantelay" When several words make one phrase, each word is changed the same way, e.g.: my big sister → ymay igbay istersay. Sentence structure remains the same as it would in English. Pronunciation of some words may be a little difficult for beginners, but people can easily understand Pig Latin with practice. Origins and history The modern version of Pig Latin appears in a 1919 Columbia Records album containing what sounds like the modern variation, by a singer named Arthur Fields. The song, called Pig Latin Love, is followed by the subtitle "I-Yay Ove-Lay ou-yay earie-day". The Three Stooges used it on multiple occasions, most notably Tassels in the Air, a 1938 short where Moe Howard attempts to teach Curley Howard how to use it, thereby conveying the rules to the audience. In an earlier (1934) episode, Three Little Pigskins, Larry Fine attempts to impress a woman with his skill in Pig Latin, but it turns out that she knows it, too. No explanation of the rules is given. A few months prior in 1934, in the Our Gang short film Washee Ironee, Spanky tries to speak to an Asian boy by using Pig Latin. Ginger Rogers sang a verse of "We're in the Money" in Pig Latin in an elaborate Busby Berkeley production number in the film Gold Diggers of 1933. The film, the third highest grossing of that year, was inducted into the National Film Registry and that song included in the all-time top 100 movie songs by the American Film Institute. Merle Travis ends his song "When My Baby Double Talks To Me" with the phrase, "What a aybybay", where the last word is Pig Latin for "baby". Two Pig Latin words that have entered into mainstream American English are "" or "icksnay", the Pig Latin version of "" (itself a borrowing of German nichts), which is used as a general negative; and "", Pig Latin for "", meaning "go away" or "get out of here". In other languages French has the loucherbem (or louchébem, or largonji) coded language, which supposedly was originally used by butchers (boucher in French). In loucherbem, the leading consonant cluster is moved to the end of the word (as in Pig Latin) and replaced by an L, and then a suffix is added at the | for "", meaning "go away" or "get out of here". In other languages French has the loucherbem (or louchébem, or largonji) coded language, which supposedly was originally used by butchers (boucher in French). In loucherbem, the leading consonant cluster is moved to the end of the word (as in Pig Latin) and replaced by an L, and then a suffix is added at the end of the word (-oche, -em, -oque, etc., depending on the word). Example: combien (how much) = lombienquès. Similar coded languages are verlan and langue de feu (see :fr:Javanais (argot)). A few louchébem words have become usual French words: fou (crazy) = loufoque or louftingue, portefeuille (wallet) = larfeuille, en douce (on the quiet) = en loucedé, à poil (naked) = à loilpé. Also similar is the widely used French argot verlan, in which the syllables of words are transposed. Verlan is a French slang that is quite similar to English pig Latin. It is spoken by separating a word into syllables and reversing the syllables. Verlan was first documented as being used as far back as the 19th century. Back in the 19th century it was spoken as code by criminals in effort to conceal illicit activities within conversations around other people, even the police. Currently, Verlan has been increasingly used in areas just outside major cities mainly populated by migrant workers. This language has served as a language bridge between many of these migrant workers from multiple countries and origins and has been so widely and readily used that it has spread into advertising, film scripts, French rap and hip-hop music, media, in some French dictionaries and in some cases, words that have been Verlanned have actually replaced their original words. The new uses of Verlan and how it has become incorporated into the French culture has all happened within just a few decades. Here is an example of some French words that have been Verlanned and their English meaning: Some verlan words have gone though a second round of such transformation. For instance reubeu is verlan for beur, which itself is verlan for Arabe. Notes References Barlow, Jessica. 2001. "Individual differences in the production of initial consonant sequences in Pig |
To the east of Poland, the most significant Polish minority lives in a long, narrow strip along either side of the Lithuania-Belarus border. Meanwhile, the flight and expulsion of Germans (1944–50), as well as the expulsion of Ukrainians and Operation Vistula, the 1947 forced resettlement of Ukrainian minorities to the Recovered Territories in the west of the country, contributed to the country's linguistic homogeneity. Dialects The inhabitants of different regions of Poland speak Polish somewhat differently, although the differences between modern-day vernacular varieties and standard Polish () appear relatively slight. Most of the middle aged and young speak vernaculars close to standard Polish, while the traditional dialects are preserved among older people in rural areas. First-language speakers of Polish have no trouble understanding each other, and non-native speakers may have difficulty recognizing the regional and social differences. The modern standard dialect, often termed as "correct Polish", is spoken or at least understood throughout the entire country. Polish has traditionally been described as consisting of four or five main regional dialects: Greater Polish, spoken in the west Lesser Polish, spoken in the south and southeast Masovian, spoken throughout the central and eastern parts of the country Silesian, spoken in the southwest (also considered a separate language, see comment below) Kashubian, spoken in Pomerania west of Gdańsk on the Baltic Sea, is thought of either as a fifth Polish dialect or a distinct language, depending on the criteria used. It contains a number of features not found elsewhere in Poland, e.g. nine distinct oral vowels (vs. the five of standard Polish) and (in the northern dialects) phonemic word stress, an archaic feature preserved from Common Slavic times and not found anywhere else among the West Slavic languages. However, it "lacks most of the linguistic and social determinants of language-hood". Many linguistic sources categorize Silesian as a dialect of Polish. However, many Silesians consider themselves a separate ethnicity and have been advocating for the recognition of a Silesian language. According to the last official census in Poland in 2011, over half a million people declared Silesian as their native language. Many sociolinguists (e.g. Tomasz Kamusella, Agnieszka Pianka, Alfred F. Majewicz, Tomasz Wicherkiewicz) assume that extralinguistic criteria decide whether a lect is an independent language or a dialect: speakers of the speech variety or/and political decisions, and this is dynamic (i.e. it changes over time). Also, research organizations such as SIL International and resources for the academic field of linguistics such as Ethnologue, Linguist List and others, for example the Ministry of Administration and Digitization recognized the Silesian language. In July 2007, the Silesian language was recognized by ISO, and was attributed an ISO code of szl. Some additional characteristic but less widespread regional dialects include: The distinctive dialect of the Gorals (Góralski) occurs in the mountainous area bordering the Czech Republic and Slovakia. The Gorals ("Highlanders") take great pride in their culture and the dialect. It exhibits some cultural influences from the Vlach shepherds who migrated from Wallachia (southern Romania) in the 14th–17th centuries. The Poznanski dialect, spoken in Poznań and to some extent in the whole region of the former Prussian Partition (excluding Upper Silesia), with noticeable German influences. In the northern and western (formerly German) regions where Poles from the territories annexed by the Soviet Union resettled after World War II, the older generation speaks a dialect of Polish characteristic of the Kresy that includes a longer pronunciation of vowels. Poles living in Lithuania (particularly in the Vilnius region), in Belarus (particularly the northwest), and in the northeast of Poland continue to speak the Eastern Borderlands dialect, which sounds "slushed" (in Polish described as zaciąganie z ruska, "speaking with a Ruthenian drawl") and is easily distinguishable. Some city dwellers, especially the less affluent population, had their own distinctive dialects - for example, the Warsaw dialect, still spoken by some of the population of Praga on the eastern bank of the Vistula. However, these city dialects are mostly extinct due to assimilation with standard Polish. Many Poles living in emigrant communities (for example, in the United States), whose families left Poland just after World War II, retain a number of minor features of Polish vocabulary as spoken in the first half of the 20th century that now sound archaic to contemporary visitors from Poland. Polish linguistics has been characterized by a strong strive towards promoting prescriptive ideas of language intervention and usage uniformity, along with normatively-oriented notions of language "correctness" (unusual by Western standards). Phonology Vowels Polish has six oral vowels (seven oral vowels in written form) which are all monophthongs, and two nasal vowels. The oral vowels are (spelled i), (spelled y and also transcribed as /ɘ/), (spelled e), (spelled a), (spelled o) and (spelled u and ó as separate letters). The nasal vowels are (spelled ę) and (spelled ą). Unlike Czech or Slovak, Polish does not retain phonemic vowel length — the letter ó, which formerly represented lengthened /ɔ/ in older forms of the language, is now vestigial and instead corresponds to /u/. Consonants The Polish consonant system shows more complexity: its characteristic features include the series of affricate and palatal consonants that resulted from four Proto-Slavic palatalizations and two further palatalizations that took place in Polish. The full set of consonants, together with their most common spellings, can be presented as follows (although other phonological analyses exist): Neutralization occurs between voiced–voiceless consonant pairs in certain environments: at the end of words (where devoicing occurs), and in certain consonant clusters (where assimilation occurs). For details, see Voicing and devoicing in the article on Polish phonology. Most Polish words are paroxytones (that is, the stress falls on the second-to-last syllable of a polysyllabic word), although there are exceptions. Consonant distribution Polish permits complex consonant clusters, which historically often arose from the disappearance of yers. Polish can have word-initial and word-medial clusters of up to four consonants, whereas word-final clusters can have up to five consonants. Examples of such clusters can be found in words such as bezwzględny ('absolute' or 'heartless', 'ruthless'), źdźbło ('blade of grass'), ('shock'), and krnąbrność ('disobedience'). A popular Polish tongue-twister (from a verse by Jan Brzechwa) is ('In Szczebrzeszyn a beetle buzzes in the reed'). Unlike languages such as Czech, Polish does not have syllabic consonants – the nucleus of a syllable is always a vowel. The consonant is restricted to positions adjacent to a vowel. It also cannot precede the letter y. Prosody The predominant stress pattern in Polish is penultimate stress – in a word of more than one syllable, the next-to-last syllable is stressed. Alternating preceding syllables carry secondary stress, e.g. in a four-syllable word, where the primary stress is on the third syllable, there will be secondary stress on the first. Each vowel represents one syllable, although the letter i normally does not represent a vowel when it precedes another vowel (it represents , palatalization of the preceding consonant, or both depending on analysis). Also the letters u and i sometimes represent only semivowels when they follow another vowel, as in autor ('author'), mostly in loanwords (so not in native nauka 'science, the act of learning', for example, nor in nativized Mateusz 'Matthew'). Some loanwords, particularly from the classical languages, have the stress on the antepenultimate (third-from-last) syllable. For example, fizyka () ('physics') is stressed on the first syllable. This may lead to a rare phenomenon of minimal pairs differing only in stress placement, for example muzyka 'music' vs. muzyka - genitive singular of muzyk 'musician'. When additional syllables are added to such words through inflection or suffixation, the stress normally becomes regular. For example, uniwersytet (, 'university') has irregular stress on the third (or antepenultimate) syllable, but the genitive uniwersytetu () and derived adjective uniwersytecki () have regular stress on the penultimate syllables. Loanwords generally become nativized to have penultimate stress. Another class of exceptions is verbs with the conditional endings -by, -bym, -byśmy, etc. These endings are not counted in determining the position of the stress; for example, zrobiłbym ('I would do') is stressed on the first syllable, and zrobilibyśmy ('we would do') on the second. According to prescriptive authorities, the same applies to the first and second person plural past tense endings -śmy, -ście, although this rule is often ignored in colloquial speech (so zrobiliśmy 'we did' should be prescriptively stressed on the second syllable, although in practice it is commonly stressed on the third as zrobiliśmy). These irregular stress patterns are explained by the fact that these endings are detachable clitics rather than true verbal inflections: for example, instead of kogo zobaczyliście? ('whom did you see?') it is possible to say kogoście zobaczyli? – here kogo retains its usual stress (first syllable) in spite of the attachment of the clitic. Reanalysis of the endings as inflections when attached to verbs causes the different colloquial stress patterns. These stress patterns are however nowadays sanctioned as part of the colloquial norm of standard Polish. Some common word combinations are stressed as if they were a single word. This applies in particular to many combinations of preposition plus a personal pronoun, such as do niej ('to her'), na nas ('on us'), przeze mnie ('because of me'), all stressed on the bolded syllable. Orthography The Polish alphabet derives from the Latin script, but includes certain additional letters formed using diacritics. The Polish alphabet was one of three major forms of Latin-based orthography developed for Western and some South Slavic languages, the others being Czech orthography and Croatian orthography, the last of these being a 19th-century invention trying to make a compromise between the first two. Kashubian uses a Polish-based system, Slovak uses a Czech-based system, and Slovene follows the Croatian one; the Sorbian languages blend the Polish and the Czech ones. Historically, Poland's once diverse and multi-ethnic population utilized many forms of scripture to write Polish. For instance, Lipka Tatars and Muslims inhabiting the eastern parts of the former Polish–Lithuanian Commonwealth wrote Polish in the Arabic alphabet. The Cyrillic script is used to a certain extent by Polish speakers in Western Belarus, especially for religious texts. The diacritics used in the Polish alphabet are the kreska (graphically similar to the acute accent) over the letters ć, ń, ó, ś, ź and through the letter in ł; the kropka (superior dot) over the letter ż, and the ogonek ("little tail") under the letters ą, ę. The letters q, v, x are used only in foreign words and names. Polish orthography is largely phonemic—there is a consistent correspondence between letters (or digraphs and trigraphs) and phonemes (for exceptions see below). The letters of the alphabet and their normal phonemic values are listed in the following table. The following digraphs and trigraphs are used: Voiced consonant letters frequently come to represent voiceless sounds (as shown in the tables); this occurs at the end of words and in certain clusters, due to the neutralization mentioned in the Phonology section above. Occasionally also voiceless consonant letters can represent voiced sounds in clusters. The spelling rule for the palatal sounds , , , and is as follows: before the vowel i the plain letters s, z, c, dz, n are used; before other vowels the combinations si, zi, ci, dzi, ni are used; when not followed by a vowel the diacritic forms ś, ź, ć, dź, ń are used. For example, the s in siwy ("grey-haired"), the si in siarka ("sulfur") and the ś in święty ("holy") all represent the sound . The exceptions to the above rule are certain loanwords from Latin, Italian, French, Russian or English—where s before i is pronounced as s, e.g. sinus, sinologia, do re mi fa sol la si do, Saint-Simon i saint-simoniści, Sierioża, Siergiej, Singapur, singiel. In other loanwords the vowel i is changed to y, e.g. Syria, Sybir, synchronizacja, Syrakuzy. The following table shows the correspondence between the sounds and spelling: Digraphs and trigraphs are used: Similar principles apply to , , and , except that these can only occur before vowels, so the spellings are k, g, (c)h, l before i, and ki, gi, (c)hi, li otherwise. Most Polish speakers, however, do not consider palatalization of k, g, (c)h or l as creating new sounds. Except in the cases mentioned above, the letter i if followed by another vowel in the same word usually represents , yet a palatalization of the previous consonant is always assumed. The letters ą and ę, when followed by plosives and affricates, represent an oral vowel followed by a nasal consonant, rather than a nasal vowel. For example, ą in dąb ("oak") is pronounced , and ę in tęcza ("rainbow") is pronounced (the nasal assimilates to the following consonant). When followed by l or ł (for example przyjęli, przyjęły), ę is pronounced as just e. When ę is at the end of the word it is often pronounced as just . Note that, depending on the word, the phoneme can be spelt h or ch, the phoneme can be spelt ż or rz, and can be spelt u or ó. In several cases it determines the meaning, for example: może ("maybe") and morze ("sea"). In occasional words, letters that normally form a digraph are pronounced separately. For example, rz represents , not , in words like zamarzać ("freeze") and in the name Tarzan. Doubled letters are usually pronounced as a single, lengthened consonant, however, some speakers might pronounce the combination as two separate sounds. There are certain clusters where a written consonant would not be pronounced. For example, the ł in the word jabłko ("apple") might be omitted in ordinary speech, leading to the pronunciation japko. Grammar Polish is a highly fusional language with relatively free word order, although the dominant arrangement is subject–verb–object (SVO). There are no articles, and subject pronouns are often dropped. Nouns belong to one of three genders: masculine, feminine and neuter. The masculine gender is also divided into subgenders : animate vs inanimate in the singular, human vs nonhuman in the plural. There are seven cases: nominative, genitive, dative, accusative, instrumental, locative and vocative. Adjectives agree with nouns in terms of gender, case, and number. Attributive adjectives most commonly precede the noun, although in certain cases, especially in fixed phrases (like język polski, "Polish (language)"), the noun may come first; the rule of thumb is that generic descriptive adjective normally precedes (e.g. piękny kwiat, "beautiful flower") while categorizing adjective often follows the noun (e.g. węgiel kamienny, "black coal"). Most short adjectives and their derived adverbs form comparatives and superlatives by inflection (the superlative is formed by prefixing naj- to the comparative). Verbs are of imperfective or perfective aspect, often occurring in pairs. Imperfective verbs have a present tense, past tense, compound future tense (except for być "to be", which has a simple future będę etc., this in turn being used to form the compound future of other verbs), subjunctive/conditional (formed with the detachable particle by), imperatives, an infinitive, present participle, present gerund and past participle. Perfective verbs have a simple future tense (formed like the present tense of imperfective verbs), past tense, subjunctive/conditional, imperatives, infinitive, present gerund and past participle. Conjugated verb forms agree with their subject in terms of person, number, and (in the case of past tense and subjunctive/conditional forms) gender. Passive-type constructions can be made using the auxiliary być or zostać ("become") with the passive participle. There is also an impersonal construction where the active verb is used (in third person singular) with no subject, but with the reflexive pronoun się present to indicate a general, unspecified subject (as in pije się wódkę "vodka is being drunk"—note that wódka appears in the accusative). A similar sentence type in the past tense uses the passive participle with the ending -o, as in widziano ludzi ("people were seen"). As in other Slavic languages, there are also subjectless sentences formed using such words as można ("it is possible") together with an infinitive. Yes-no questions (both direct and indirect) are formed by placing the word czy at the start. Negation uses the word nie, before the verb or other item being negated; nie is still added before the verb even if the sentence also contains other negatives such as nigdy ("never") or nic ("nothing"), effectively creating a double negative. Cardinal numbers have a complex system of inflection and agreement. Zero and cardinal numbers higher than five (except for those ending with the digit 2, 3 or 4 but not ending with 12, 13 or 14) govern the genitive case rather than the nominative or accusative. Special forms of numbers (collective numerals) are used with certain classes of noun, which include dziecko ("child") and exclusively plural nouns such as drzwi ("door"). Borrowed words Polish has, over the centuries, borrowed a number of words from other languages. When borrowing, pronunciation was adapted to Polish phonemes and spelling was altered to match Polish orthography. In addition, word endings are liberally applied to almost any word to produce verbs, nouns, adjectives, as well as adding the appropriate endings for cases of nouns, adjectives, diminutives, double-diminutives, augmentatives, etc. Depending | countries such as Canada, Argentina, Brazil, Israel, Australia, the United Kingdom and the United States. History Polish began to emerge as a distinct language around the 10th century, the process largely triggered by the establishment and development of the Polish state. Mieszko I, ruler of the Polans tribe from the Greater Poland region, united a few culturally and linguistically related tribes from the basins of the Vistula and Oder before eventually accepting baptism in 966. With Christianity, Poland also adopted the Latin alphabet, which made it possible to write down Polish, which until then had existed only as a spoken language. The precursor to modern Polish is the Old Polish language. Ultimately, Polish is thought to descend from the unattested Proto-Slavic language. Polish was a lingua franca from 1500 to 1700 in Central and parts of Eastern Europe, because of the political, cultural, scientific and military influence of the former Polish–Lithuanian Commonwealth. The Book of Henryków (Polish: , ), contains the earliest known sentence written in the Polish language: Day, ut ia pobrusa, a ti poziwai (in modern orthography: Daj, uć ja pobrusza, a ti pocziwaj; the corresponding sentence in modern Polish: Daj, niech ja pomielę, a ty odpoczywaj or Pozwól, że ja będę mełł, a ty odpocznij; and in English: Come, let me grind, and you take a rest), written around 1270. The medieval recorder of this phrase, the Cistercian monk Peter of the Henryków monastery, noted that "Hoc est in polonico" ("This is in Polish"). Geographic distribution Poland is one of the most linguistically homogeneous European countries; nearly 97% of Poland's citizens declare Polish as their first language. Elsewhere, Poles constitute large minorities in areas which were once administered or occupied by Poland, notably in neighboring Lithuania, Belarus, and Ukraine. Polish is the most widely used minority language in Lithuania's Vilnius County (26% of the population, according to the 2001 census results, with Vilnius having been part of Poland from 1922 until 1939) and is found elsewhere in southeastern Lithuania. In Ukraine, it is most common in western Lviv and Volyn Oblasts, while in West Belarus it is used by the significant Polish minority, especially in the Brest and Grodno regions and in areas along the Lithuanian border. There are significant numbers of Polish speakers among Polish emigrants and their descendants in many other countries. In the United States, Polish Americans number more than 11 million but most of them cannot speak Polish fluently. According to the 2000 United States Census, 667,414 Americans of age five years and over reported Polish as the language spoken at home, which is about 1.4% of people who speak languages other than English, 0.25% of the US population, and 6% of the Polish-American population. The largest concentrations of Polish speakers reported in the census (over 50%) were found in three states: Illinois (185,749), New York (111,740), and New Jersey (74,663). Enough people in these areas speak Polish that PNC Financial Services (which has a large number of branches in all of these areas) offer services available in Polish at all of their cash machines in addition to English and Spanish. According to the 2011 census there are now over 500,000 people in England and Wales who consider Polish to be their "main" language. In Canada, there is a significant Polish Canadian population: There are 242,885 speakers of Polish according to the 2006 census, with a particular concentration in Toronto (91,810 speakers) and Montreal. The geographical distribution of the Polish language was greatly affected by the territorial changes of Poland immediately after World War II and Polish population transfers (1944–46). Poles settled in the "Recovered Territories" in the west and north, which had previously been mostly German-speaking. Some Poles remained in the previously Polish-ruled territories in the east that were annexed by the USSR, resulting in the present-day Polish-speaking minorities in Lithuania, Belarus, and Ukraine, although many Poles were expelled or emigrated from those areas to areas within Poland's new borders. To the east of Poland, the most significant Polish minority lives in a long, narrow strip along either side of the Lithuania-Belarus border. Meanwhile, the flight and expulsion of Germans (1944–50), as well as the expulsion of Ukrainians and Operation Vistula, the 1947 forced resettlement of Ukrainian minorities to the Recovered Territories in the west of the country, contributed to the country's linguistic homogeneity. Dialects The inhabitants of different regions of Poland speak Polish somewhat differently, although the differences between modern-day vernacular varieties and standard Polish () appear relatively slight. Most of the middle aged and young speak vernaculars close to standard Polish, while the traditional dialects are preserved among older people in rural areas. First-language speakers of Polish have no trouble understanding each other, and non-native speakers may have difficulty recognizing the regional and social differences. The modern standard dialect, often termed as "correct Polish", is spoken or at least understood throughout the entire country. Polish has traditionally been described as consisting of four or five main regional dialects: Greater Polish, spoken in the west Lesser Polish, spoken in the south and southeast Masovian, spoken throughout the central and eastern parts of the country Silesian, spoken in the southwest (also considered a separate language, see comment below) Kashubian, spoken in Pomerania west of Gdańsk on the Baltic Sea, is thought of either as a fifth Polish dialect or a distinct language, depending on the criteria used. It contains a number of features not found elsewhere in Poland, e.g. nine distinct oral vowels (vs. the five of standard Polish) and (in the northern dialects) phonemic word stress, an archaic feature preserved from Common Slavic times and not found anywhere else among the West Slavic languages. However, it "lacks most of the linguistic and social determinants of language-hood". Many linguistic sources categorize Silesian as a dialect of Polish. However, many Silesians consider themselves a separate ethnicity and have been advocating for the recognition of a Silesian language. According to the last official census in Poland in 2011, over half a million people declared Silesian as their native language. Many sociolinguists (e.g. Tomasz Kamusella, Agnieszka Pianka, Alfred F. Majewicz, Tomasz Wicherkiewicz) assume that extralinguistic criteria decide whether a lect is an independent language or a dialect: speakers of the speech variety or/and political decisions, and this is dynamic (i.e. it changes over time). Also, research organizations such as SIL International and resources for the academic field of linguistics such as Ethnologue, Linguist List and others, for example the Ministry of Administration and Digitization recognized the Silesian language. In July 2007, the Silesian language was recognized by ISO, and was attributed an ISO code of szl. Some additional characteristic but less widespread regional dialects include: The distinctive dialect of the Gorals (Góralski) occurs in the mountainous area bordering the Czech Republic and Slovakia. The Gorals ("Highlanders") take great pride in their culture and the dialect. It exhibits some cultural influences from the Vlach shepherds who migrated from Wallachia (southern Romania) in the 14th–17th centuries. The Poznanski dialect, spoken in Poznań and to some extent in the whole region of the former Prussian Partition (excluding Upper Silesia), with noticeable German influences. In the northern and western (formerly German) regions where Poles from the territories annexed by the Soviet Union resettled after World War II, the older generation speaks a dialect of Polish characteristic of the Kresy that includes a longer pronunciation of vowels. Poles living in Lithuania (particularly in the Vilnius region), in Belarus (particularly the northwest), and in the northeast of Poland continue to speak the Eastern Borderlands dialect, which sounds "slushed" (in Polish described as zaciąganie z ruska, "speaking with a Ruthenian drawl") and is easily distinguishable. Some city dwellers, especially the less affluent population, had their own distinctive dialects - for example, the Warsaw dialect, still spoken by some of the population of Praga on the eastern bank of the Vistula. However, these city dialects are mostly extinct due to assimilation with standard Polish. Many Poles living in emigrant communities (for example, in the United States), whose families left Poland just after World War II, retain a number of minor features of Polish vocabulary as spoken in the first half of the 20th century that now sound archaic to contemporary visitors from Poland. Polish linguistics has been characterized by a strong strive towards promoting prescriptive ideas of language intervention and usage uniformity, along with normatively-oriented notions of language "correctness" (unusual by Western standards). Phonology Vowels Polish has six oral vowels (seven oral vowels in written form) which are all monophthongs, and two nasal vowels. The oral vowels are (spelled i), (spelled y and also transcribed as /ɘ/), (spelled e), (spelled a), (spelled o) and (spelled u and ó as separate letters). The nasal vowels are (spelled ę) and (spelled ą). Unlike Czech or Slovak, Polish does not retain phonemic vowel length — the letter ó, which formerly represented lengthened /ɔ/ in older forms of the language, is now vestigial and instead corresponds to /u/. Consonants The Polish consonant system shows more complexity: its characteristic features include the series of affricate and palatal consonants that resulted from four Proto-Slavic palatalizations and two further palatalizations that took place in Polish. The full set of consonants, together with their most common spellings, can be presented as follows (although other phonological analyses exist): Neutralization occurs between voiced–voiceless consonant pairs in certain environments: at the end of words (where devoicing occurs), and in certain consonant clusters (where assimilation occurs). For details, see Voicing and devoicing in the article on Polish phonology. Most Polish words are paroxytones (that is, the stress falls on the second-to-last syllable of a polysyllabic word), although there are exceptions. Consonant distribution Polish permits complex consonant clusters, which historically often arose from the disappearance of yers. Polish can have word-initial and word-medial clusters of up to four consonants, whereas word-final clusters can have up to five consonants. Examples of such clusters can be found in words such as bezwzględny ('absolute' or 'heartless', 'ruthless'), źdźbło ('blade of grass'), ('shock'), and krnąbrność ('disobedience'). A popular Polish tongue-twister (from a verse by Jan Brzechwa) is ('In Szczebrzeszyn a beetle buzzes in the reed'). Unlike languages such as Czech, Polish does not have syllabic consonants – the nucleus of a syllable is always a vowel. The consonant is restricted to positions adjacent to a vowel. It also cannot precede the letter y. Prosody The predominant stress pattern in Polish is penultimate stress – in a word of more than one syllable, the next-to-last syllable is stressed.

Also the letters u and i sometimes represent only semivowels when they follow another vowel, as in autor ('author'), mostly in loanwords (so not in native nauka 'science, the act of learning', for example, nor in nativized Mateusz 'Matthew'). Some loanwords, particularly from the classical languages, have the stress on the antepenultimate (third-from-last) syllable. For example, fizyka () ('physics') is stressed on the first syllable. This may lead to a rare phenomenon of minimal pairs differing only in stress placement, for example muzyka 'music' vs. muzyka - genitive singular of muzyk 'musician'. When additional syllables are added to such words through inflection or suffixation, the stress normally becomes regular. For example, uniwersytet (, 'university') has irregular stress on the third (or antepenultimate) syllable, but the genitive uniwersytetu () and derived adjective uniwersytecki () have regular stress on the penultimate syllables. Loanwords generally become nativized to have penultimate stress. Another class of exceptions is verbs with the conditional endings -by, -bym, -byśmy, etc. These endings are not counted in determining the position of the stress; for example, zrobiłbym ('I would do') is stressed on the first syllable, and zrobilibyśmy ('we would do') on the second. According to prescriptive authorities, the same applies to the first and second person plural past tense endings -śmy, -ście, although this rule is often ignored in colloquial speech (so zrobiliśmy 'we did' should be prescriptively stressed on the second syllable, although in practice it is commonly stressed on the third as zrobiliśmy). These irregular stress patterns are explained by the fact that these endings are detachable clitics rather than true verbal inflections: for example, instead of kogo zobaczyliście? ('whom did you see?') it is possible to say kogoście zobaczyli? – here kogo retains its usual stress (first syllable) in spite of the attachment of the clitic. Reanalysis of the endings as inflections when attached to verbs causes the different colloquial stress patterns. These stress patterns are however nowadays sanctioned as part of the colloquial norm of standard Polish. Some common word combinations are stressed as if they were a single word. This applies in particular to many combinations of preposition plus a personal pronoun, such as do niej ('to her'), na nas ('on us'), przeze mnie ('because of me'), all stressed on the bolded syllable. Orthography The Polish alphabet derives from the Latin script, but includes certain additional letters formed using diacritics. The Polish alphabet was one of three major forms of Latin-based orthography developed for Western and some South Slavic languages, the others being Czech orthography and Croatian orthography, the last of these being a 19th-century invention trying to make a compromise between the first two. Kashubian uses a Polish-based system, Slovak uses a Czech-based system, and Slovene follows the Croatian one; the Sorbian languages blend the Polish and the Czech ones. Historically, Poland's once diverse and multi-ethnic population utilized many forms of scripture to write Polish. For instance, Lipka Tatars and Muslims inhabiting the eastern parts of the former Polish–Lithuanian Commonwealth wrote Polish in the Arabic alphabet. The Cyrillic script is used to a certain extent by Polish speakers in Western Belarus, especially for religious texts. The diacritics used in the Polish alphabet are the kreska (graphically similar to the acute accent) over the letters ć, ń, ó, ś, ź and through the letter in ł; the kropka (superior dot) over the letter ż, and the ogonek ("little tail") under the letters ą, ę. The letters q, v, x are used only in foreign words and names. Polish orthography is largely phonemic—there is a consistent correspondence between letters (or digraphs and trigraphs) and phonemes (for exceptions see below). The letters of the alphabet and their normal phonemic values are listed in the following table. The following digraphs and trigraphs are used: Voiced consonant letters frequently come to represent voiceless sounds (as shown in the tables); this occurs at the end of words and in certain clusters, due to the neutralization mentioned in the Phonology section above. Occasionally also voiceless consonant letters can represent voiced sounds in clusters. The spelling rule for the palatal sounds , , , and is as follows: before the vowel i the plain letters s, z, c, dz, n are used; before other vowels the combinations si, zi, ci, dzi, ni are used; when not followed by a vowel the diacritic forms ś, ź, ć, dź, ń are used. For example, the s in siwy ("grey-haired"), the si in siarka ("sulfur") and the ś in święty ("holy") all represent the sound . The exceptions to the above rule are certain loanwords from Latin, Italian, French, Russian or English—where s before i is pronounced as s, e.g. sinus, sinologia, do re mi fa sol la si do, Saint-Simon i saint-simoniści, Sierioża, Siergiej, Singapur, singiel. In other loanwords the vowel i is changed to y, e.g. Syria, Sybir, synchronizacja, Syrakuzy. The following table shows the correspondence between the sounds and spelling: Digraphs and trigraphs are used: Similar principles apply to , , and , except that these can only occur before vowels, so the spellings are k, g, (c)h, l before i, and ki, gi, (c)hi, li otherwise. Most Polish speakers, however, do not consider palatalization of k, g, (c)h or l as creating new sounds. Except in the cases mentioned above, the letter i if followed by another vowel in the same word usually represents , yet a palatalization of the previous consonant is always assumed. The letters ą and ę, when followed by plosives and affricates, represent an oral vowel followed by a nasal consonant, rather than a nasal vowel. For example, ą in dąb ("oak") is pronounced , and ę in tęcza ("rainbow") is pronounced (the nasal assimilates to the following consonant). When followed by l or ł (for example przyjęli, przyjęły), ę is pronounced as just e. When ę is at the end of the word it is often pronounced as just . Note that, depending on the word, the phoneme can be spelt h or ch, the phoneme can be spelt ż or rz, and can be spelt u or ó. In several cases it determines the meaning, for example: może ("maybe") and morze ("sea"). In occasional words, letters that normally form a digraph are pronounced separately. For example, rz represents , not , in words like zamarzać ("freeze") and in the name Tarzan. Doubled letters are usually pronounced as a single, lengthened consonant, however, some speakers might pronounce the combination as two separate sounds. There are certain clusters where |
novels, and short-fiction magazines of the 19th century. Although many respected writers wrote for pulps, the magazines were best known for their lurid, exploitative, and sensational subject matter, even though this was but a small part of what existed in the pulps. Successors of pulps include paperback books, digest magazines, and men's adventure magazines. Modern superhero comic books are sometimes considered descendants of "hero pulps"; pulp magazines often featured illustrated novel-length stories of heroic characters, such as Flash Gordon, The Shadow, Doc Savage, and The Phantom Detective. History Origins The first "pulp" was Frank Munsey's revamped Argosy magazine of 1896, with about 135,000 words (192 pages) per issue, on pulp paper with untrimmed edges, and no illustrations, even on the cover. The steam-powered printing press had been in widespread use for some time, enabling the boom in dime novels; prior to Munsey, however, no one had combined cheap printing, cheap paper and cheap authors in a package that provided affordable entertainment to young working-class people. In six years, Argosy went from a few thousand copies per month to over half a million. Street & Smith, a dime novel and boys' weekly publisher, was next on the market. Seeing Argosys success, they launched The Popular Magazine in 1903, which they billed as the "biggest magazine in the world" by virtue of its being two pages (the interior sides of the front and back cover) longer than Argosy. Due to differences in page layout however, the magazine had substantially less text than Argosy. The Popular Magazine did introduce color covers to pulp publishing, and the magazine began to take off when in 1905 the publishers acquired the rights to serialize Ayesha, by H. Rider Haggard, a sequel to his popular novel She. Haggard's Lost World genre influenced several key pulp writers, including Edgar Rice Burroughs, Robert E. Howard, Talbot Mundy and Abraham Merritt. In 1907, the cover price rose to 15 cents and 30 pages were added to each issue; along with establishing a stable of authors for each magazine, this change proved successful and circulation began to approach that of Argosy. Street and Smith's next innovation was the introduction of specialized genre pulps, with each magazine focusing on a particular genre, such as detective stories, romance, etc. Peak of popularity At their peak of popularity in the 1920s-1940s, the most successful pulps sold up to one million copies per issue. In 1934, Frank Gruber said there were some 150 pulp titles. The most successful pulp magazines were Argosy, Adventure, Blue Book and Short Stories, collectively described by some pulp historians as "The Big Four". Among the best-known other titles of this period were Amazing Stories, Black Mask, Dime Detective, Flying Aces, Horror Stories, Love Story Magazine, Marvel Tales, Oriental Stories, Planet Stories, Spicy Detective, Startling Stories, Thrilling Wonder Stories, Unknown, Weird Tales and Western Story Magazine. During the economic hardships of the Great Depression, pulps provided affordable content to the masses, and were one of the primary forms of entertainment, along with film and radio. Although pulp magazines were primarily an American phenomenon, there were also a number of British pulp magazines published between the Edwardian era and World War II. Notable UK pulps included Pall Mall Magazine, The Novel Magazine, Cassell's Magazine, The Story-Teller, The Sovereign Magazine, Hutchinson's Adventure-Story and Hutchinson's Mystery-Story. The German fantasy magazine Der Orchideengarten had a similar format to American pulp magazines, in that it was printed on rough pulp paper and heavily illustrated. World War II and market decline During the Second World War paper shortages had a serious impact on pulp production, starting a steady rise in costs and the decline of the pulps. Beginning with Ellery Queen's Mystery Magazine in 1941, pulp magazines began to switch to digest size; smaller, thicker magazines. In 1949, Street & Smith closed most of their pulp magazines in order to move upmarket and produce slicks. Competition from comic-books and paperback novels further eroded the pulps’ marketshare, but it was the widespread expansion of television that sounded the death knell of the pulps. In a more affluent post-war America, the price gap compared to slick magazines was far less significant. In the 1950s, men's adventure magazines began to replace the pulp. The 1957 liquidation of the American News Company, then the primary distributor of pulp magazines, has sometimes been taken as marking the end of the "pulp era"; by that date, many of the famous pulps of the previous generation, including Black Mask, The Shadow, Doc Savage, and Weird Tales, were defunct. Almost all of the few remaining pulp magazines are science fiction or mystery magazines now in formats similar to "digest size", such as Analog Science Fiction and Fact and Ellery Queen's Mystery Magazine. The format is still in use for some lengthy serials, like the German science fiction weekly Perry Rhodan (over 3,000 issues as of 2019). Over the course of their evolution, there were a huge number of pulp magazine titles; Harry Steeger of Popular Publications claimed that his company alone had published over 300, and at their peak they were publishing 42 titles per month. Many titles of course survived only briefly. While the most popular titles were monthly, many were bimonthly and some were quarterly. The collapse of the pulp industry changed the landscape of publishing because pulps were the single largest sales outlet for short stories. Combined | the most successful pulps sold up to one million copies per issue. In 1934, Frank Gruber said there were some 150 pulp titles. The most successful pulp magazines were Argosy, Adventure, Blue Book and Short Stories, collectively described by some pulp historians as "The Big Four". Among the best-known other titles of this period were Amazing Stories, Black Mask, Dime Detective, Flying Aces, Horror Stories, Love Story Magazine, Marvel Tales, Oriental Stories, Planet Stories, Spicy Detective, Startling Stories, Thrilling Wonder Stories, Unknown, Weird Tales and Western Story Magazine.

Many titles of course survived only briefly. While the most popular titles were monthly, many were bimonthly and some were quarterly. The collapse of the pulp industry changed the landscape of publishing because pulps were the single largest sales outlet for short stories. Combined with the decrease in slick magazine fiction markets, writers attempting to support themselves by creating fiction switched to novels and book-length anthologies of shorter pieces. Some ex-pulp writers like Hugh B. Cave and Robert Leslie Bellem moved on to writing for television by the 1950s. Genres Pulp magazines often contained a wide variety of genre fiction, including, but not limited to, adventure aviation detective/mystery fantasy gangster horror/occult (including "weird menace") humor railroad romance science fiction Série Noire (French crime mystery) "spicy/saucy" (soft porn) sports war Westerns (also see dime Western); the Colorado artist Arthur Roy Mitchell is particularly known for his sketches of the covers of such western magazines. The American Old West was a mainstay genre of early turn of the 20th century novels as well as later pulp magazines, and lasted longest of all the traditional pulps. In many ways, the later men's adventure ("the sweats") was the replacement of pulps. Many classic science fiction and crime novels were originally serialized in pulp magazines such as Weird Tales, Amazing Stories, and Black Mask. Notable original characters While the majority of pulp magazines were anthology titles featuring many different authors, characters and settings, some of the most enduring magazines were those that featured a single recurring character. These were often referred to as "hero pulps" because the recurring character was almost always a larger-than-life hero in the mold of Doc Savage or The Shadow. Popular pulp characters that headlined in their own magazines: Popular pulp characters who appeared in anthology titles such as All-Story or Weird Tales: Illustrators Pulp covers were printed in color on higher-quality (slick) paper. They were famous for their half-dressed damsels in distress, usually awaiting a rescuing hero. Cover art played a major part in the marketing of pulp magazines. The early pulp magazines could boast covers by some distinguished American artists; The Popular Magazine had covers by N.C. Wyeth, and Edgar Franklin Wittmack contributed cover art to Argosy and Short Stories. Later, many artists specialized in creating covers mainly for the pulps; a number of the most successful cover artists became as popular as the authors featured on the interior pages. Among the most famous pulp artists were Walter Baumhofer, Earle K. Bergey, Margaret Brundage, Edd Cartier, Virgil Finlay, Frank R. Paul, Norman Saunders, Emmett Watson, Nick Eggenhofer, (who specialized in Western illustrations), Hugh J. Ward, George Rozen, and Rudolph Belarski. Covers were important enough to sales that sometimes they would be designed first; authors would then be shown the cover art and asked to write a story to match. Later pulps began to feature interior illustrations, depicting elements of the stories. The drawings were printed in black ink on the same cream-colored paper used for the text, and had to use specific techniques to avoid blotting on the coarse texture of the cheap pulp. Thus, fine lines and heavy detail were usually not an option. Shading was by crosshatching or pointillism, and even that had to be limited and coarse. Usually the art was black lines on the paper's background, but Finlay and a few others did some work that was primarily white lines against large dark areas. Authors and editors Another way pulps kept costs down was by paying authors less than other markets; thus many eminent authors started out in the pulps before they were successful enough to sell to better-paying markets, and similarly, well-known authors whose careers were slumping or who wanted a few quick dollars could bolster their income with sales to pulps. Additionally, some of the earlier pulps solicited stories from amateurs who were quite happy to see their words in print and could thus be paid token amounts. There were also career pulp writers, capable of turning out huge amounts of prose on a steady basis, often with the aid of dictation to stenographers, machines or typists. Before he became a novelist, Upton Sinclair was turning out at least 8,000 words per day seven days a week for the pulps, keeping two stenographers fully employed. Pulps would often have their authors use multiple pen names so that they could use multiple stories by the same person in one issue, or use a given author's stories in three or more successive issues, while still appearing to have varied content. One advantage pulps provided to authors was that they paid upon acceptance for material instead of on publication; since a story might be accepted months or even years before publication, to a working writer this was a crucial difference in cash flow. Some pulp editors became known for cultivating good fiction and interesting features in their magazines. Preeminent pulp magazine editors included Arthur Sullivant Hoffman (Adventure), Robert H. Davis (All-Story Weekly), Harry E. Maule (Short Stories), Donald Kennicott (Blue Book), Joseph T. Shaw (Black Mask), Farnsworth Wright (Weird Tales, Oriental Stories), John W. Campbell (Astounding Science Fiction, Unknown) and Daisy Bacon (Love Story Magazine, Detective Story Magazine). Authors featured Well-known authors who wrote for pulps include: Sinclair Lewis, first American winner of the Nobel Prize in Literature, worked as an editor for Adventure, writing filler paragraphs (brief facts or amusing anecdotes designed to fill small gaps in page layout), advertising copy and a few stories.

bidding, although it is intended to realize the phoneme in the first word and in the second. This appears to contradict biuniqueness. For further discussion of such cases, see the next section. Neutralization and archiphonemes Phonemes that are contrastive in certain environments may not be contrastive in all environments. In the environments where they do not contrast, the contrast is said to be neutralized. In these positions it may become less clear which phoneme a given phone represents. Absolute neutralization is a phenomenon in which a segment of the underlying representation is not realized in any of its phonetic representations (surface forms). The term was introduced by Paul Kiparsky (1968), and contrasts with contextual neutralization where some phonemes are not contrastive in certain environments. Some phonologists prefer not to specify a unique phoneme in such cases, since to do so would mean providing redundant or even arbitrary information – instead they use the technique of underspecification. An archiphoneme is an object sometimes used to represent an underspecified phoneme. An example of neutralization is provided by the Russian vowels and . These phonemes are contrasting in stressed syllables, but in unstressed syllables the contrast is lost, since both are reduced to the same sound, usually (for details, see vowel reduction in Russian). In order to assign such an instance of to one of the phonemes and , it is necessary to consider morphological factors (such as which of the vowels occurs in other forms of the words, or which inflectional pattern is followed). In some cases even this may not provide an unambiguous answer. A description using the approach of underspecification would not attempt to assign to a specific phoneme in some or all of these cases, although it might be assigned to an archiphoneme, written something like , which reflects the two neutralized phonemes in this position, or }, reflecting its unmerged values. A somewhat different example is found in English, with the three nasal phonemes . In word-final position these all contrast, as shown by the minimal triplet sum , sun , sung . However, before a stop such as (provided there is no morpheme boundary between them), only one of the nasals is possible in any given position: before , before or , and before , as in limp, lint, link (, , ). The nasals are therefore not contrastive in these environments, and according to some theorists this makes it inappropriate to assign the nasal phones heard here to any one of the phonemes (even though, in this case, the phonetic evidence is unambiguous). Instead they may analyze these phones as belonging to a single archiphoneme, written something like , and state the underlying representations of limp, lint, link to be . This latter type of analysis is often associated with Nikolai Trubetzkoy of the Prague school. Archiphonemes are often notated with a capital letter within double virgules or pipes, as with the examples and given above. Other ways the second of these has been notated include , and . Another example from English, but this time involving complete phonetic convergence as in the Russian example, is the flapping of and in some American English (described above under Biuniqueness). Here the words betting and bedding might both be pronounced . Under the generative grammar theory of linguistics, if a speaker applies such flapping consistently, morphological evidence (the pronunciation of the related forms bet and bed, for example) would reveal which phoneme the flap represents, once it is known which morpheme is being used. However, other theorists would prefer not to make such a determination, and simply assign the flap in both cases to a single archiphoneme, written (for example) . Further mergers in English are plosives after , where conflate with , as suggested by the alternative spellings sketti and sghetti. That is, there is no particular reason to transcribe spin as rather than as , other than its historical development, and it might be less ambiguously transcribed . Morphophonemes A morphophoneme is a theoretical unit at a deeper level of abstraction than traditional phonemes, and is taken to be a unit from which morphemes are built up. A morphophoneme within a morpheme can be expressed in different ways in different allomorphs of that morpheme (according to morphophonological rules). For example, the English plural morpheme -s appearing in words such as cats and dogs can be considered to be a single morphophoneme, which might be transcribed (for example) or , and which is realized as phonemically after most voiceless consonants (as in cats) and as in other cases (as in dogs). Numbers of phonemes in different languages All known languages use only a small subset of the many possible sounds that the human speech organs can produce, and, because of allophony, the number of distinct phonemes will generally be smaller than the number of identifiably different sounds. Different languages vary considerably in the number of phonemes they have in their systems (although apparent variation may sometimes result from the different approaches taken by the linguists doing the analysis). The total phonemic inventory in languages varies from as few as 11 in Rotokas and Pirahã to as many as 141 in !Xũ. The number of phonemically distinct vowels can be as low as two, as in Ubykh and Arrernte. At the other extreme, the Bantu language Ngwe has 14 vowel qualities, 12 of which may occur long or short, making 26 oral vowels, plus six nasalized vowels, long and short, making a total of 38 vowels; while !Xóõ achieves 31 pure vowels, not counting its additional variation by vowel length, by varying the phonation. As regards consonant phonemes, Puinave and the Papuan language Tauade each have just seven, and Rotokas has only six. !Xóõ, on the other hand, has somewhere around 77, and Ubykh 81. The English language uses a rather large set of 13 to 21 vowel phonemes, including diphthongs, although its 22 to 26 consonants are close to average. Across all languages, the average number of consonant phonemes per language is about 22, while the average number of vowel phonemes is about 8. Some languages, such as French, have no phonemic tone or stress, while Cantonese and several of the Kam–Sui languages have nine tones, and one of the Kru languages, Wobé, has been claimed to have 14, though this is disputed. The most common vowel system consists of the five vowels . The most common consonants are . Relatively few languages lack any of these consonants, although it does happen: for example, Arabic lacks , standard Hawaiian lacks , Mohawk and Tlingit lack and , Hupa lacks both and a simple , colloquial Samoan lacks and , while Rotokas and Quileute lack and . The non-uniqueness of phonemic solutions During the development of phoneme theory in the mid-20th century phonologists were concerned not only with the procedures and principles involved in producing a phonemic analysis of the sounds of a given language, but also with the reality or uniqueness of the phonemic solution. These were central concerns of phonology. Some writers took the position expressed by Kenneth Pike: "There is only one accurate phonemic analysis for a given set of data", while others believed that different analyses, equally valid, could be made for the same data. Yuen Ren Chao (1934), in his article "The non-uniqueness of phonemic solutions of phonetic systems" stated "given the sounds of a language, there are usually more than one possible way of reducing them to a set of phonemes, and these different systems or solutions are not simply correct or incorrect, but may be regarded only as being good or bad for various purposes". The linguist F.W. Householder referred to this argument within linguistics as "God's Truth" (i.e. the stance that a given language has an intrinsic structure to be discovered) vs. "hocus-pocus" (i.e. the stance that any proposed, coherent structure is as good as any other). Different analyses of the English vowel system may be used to illustrate this. The article English phonology states that "English has a particularly large number of vowel phonemes" and that "there are 20 vowel phonemes in Received Pronunciation, 14–16 in General American and 20–21 in Australian English". Although these figures are often quoted as fact, they actually reflect just one of many possible analyses, and later in the English Phonology article an alternative analysis is suggested in which some diphthongs and long vowels may be interpreted as comprising a short vowel linked to either or . The fullest exposition of this approach is found in Trager and Smith (1951), where all long vowels and diphthongs ("complex nuclei") are made up of a short vowel combined with either , or (plus for rhotic accents), each comprising two phonemes. The transcription for the vowel normally transcribed would instead be , would be and would be , or /ar/ in a rhotic accent if there is an in the spelling. It is also possible to treat English long vowels and diphthongs as combinations of two vowel phonemes, with long vowels treated as a sequence of two short vowels, so that 'palm' would be represented as /paam/. English can thus be said to have around seven vowel phonemes, or even six if schwa were treated as an allophone of or of other short vowels. In the same period there was disagreement about the correct basis for a phonemic analysis. The structuralist position was that the analysis should be made purely on the basis of the sound elements and their distribution, with no reference to extraneous factors such as grammar, morphology or the intuitions of the native speaker; this position is strongly associated with Leonard Bloomfield. Zellig Harris claimed that it is possible to discover the phonemes of a language purely by examining the distribution of phonetic segments. Referring to mentalistic definitions of the phoneme, Twaddell (1935) stated "Such a definition is invalid because (1) we have no right to guess about the linguistic workings of an inaccessible 'mind', and (2) we can secure no advantage from such guesses. The linguistic processes of the 'mind' as such are quite simply unobservable; and introspection about linguistic processes is notoriously a fire in a wooden stove." This approach was opposed to that of Edward Sapir, who gave an important role to native speakers' intuitions about where a | they are considered separate phonemes. Phonologists have sometimes had recourse to "near minimal pairs" to show that speakers of the language perceive two sounds as significantly different even if no exact minimal pair exists in the lexicon. It is virtually impossible to find a minimal pair to distinguish English from , yet it seems uncontroversial to claim that the two consonants are distinct phonemes. The two words 'pressure' and 'pleasure' can serve as a near minimal pair. Suprasegmental phonemes Besides segmental phonemes such as vowels and consonants, there are also suprasegmental features of pronunciation (such as tone and stress, syllable boundaries and other forms of juncture, nasalization and vowel harmony), which, in many languages, can change the meaning of words and so are phonemic. Phonemic stress is encountered in languages such as English. For example, the word invite stressed on the second syllable is a verb, but when stressed on the first syllable (without changing any of the individual sounds), it becomes a noun. The position of the stress in the word affects the meaning, so a full phonemic specification (providing enough detail to enable the word to be pronounced unambiguously) would include indication of the position of the stress: for the verb, for the noun. In other languages, such as French, word stress cannot have this function (its position is generally predictable) and is therefore not phonemic (and is not usually indicated in dictionaries). Phonemic tones are found in languages such as Mandarin Chinese, in which a given syllable can have five different tonal pronunciations: The tone "phonemes" in such languages are sometimes called tonemes. Languages such as English do not have phonemic tone, although they use intonation for functions such as emphasis and attitude. Distribution of allophones When a phoneme has more than one allophone, the one actually heard at a given occurrence of that phoneme may be dependent on the phonetic environment (surrounding sounds) – allophones which normally cannot appear in the same environment are said to be in complementary distribution. In other cases the choice of allophone may be dependent on the individual speaker or other unpredictable factors – such allophones are said to be in free variation, but allophones are still selected in a specific phonetic context, not the other way around. Background and related ideas The term phonème (from , "sound made, utterance, thing spoken, speech, language") was reportedly first used by A. Dufriche-Desgenettes in 1873, but it referred only to a speech sound. The term phoneme as an abstraction was developed by the Polish linguist Jan Niecisław Baudouin de Courtenay and his student Mikołaj Kruszewski during 1875–1895. The term used by these two was fonema, the basic unit of what they called psychophonetics. Daniel Jones became the first linguist in the western world to use the term phoneme in its current sense, employing the word in his article "The phonetic structure of the Sechuana Language". The concept of the phoneme was then elaborated in the works of Nikolai Trubetzkoy and others of the Prague School (during the years 1926–1935), and in those of structuralists like Ferdinand de Saussure, Edward Sapir, and Leonard Bloomfield. Some structuralists (though not Sapir) rejected the idea of a cognitive or psycholinguistic function for the phoneme. Later, it was used and redefined in generative linguistics, most famously by Noam Chomsky and Morris Halle, and remains central to many accounts of the development of modern phonology. As a theoretical concept or model, though, it has been supplemented and even replaced by others. Some linguists (such as Roman Jakobson and Morris Halle) proposed that phonemes may be further decomposable into features, such features being the true minimal constituents of language. Features overlap each other in time, as do suprasegmental phonemes in oral language and many phonemes in sign languages. Features could be characterized in different ways: Jakobson and colleagues defined them in acoustic terms, Chomsky and Halle used a predominantly articulatory basis, though retaining some acoustic features, while Ladefoged's system is a purely articulatory system apart from the use of the acoustic term 'sibilant'. In the description of some languages, the term chroneme has been used to indicate contrastive length or duration of phonemes. In languages in which tones are phonemic, the tone phonemes may be called tonemes. Though not all scholars working on such languages use these terms, they are by no means obsolete. By analogy with the phoneme, linguists have proposed other sorts of underlying objects, giving them names with the suffix -eme, such as morpheme and grapheme. These are sometimes called emic units. The latter term was first used by Kenneth Pike, who also generalized the concepts of emic and etic description (from phonemic and phonetic respectively) to applications outside linguistics. Restrictions on occurrence Languages do not generally allow words or syllables to be built of any arbitrary sequences of phonemes; there are phonotactic restrictions on which sequences of phonemes are possible and in which environments certain phonemes can occur. Phonemes that are significantly limited by such restrictions may be called restricted phonemes. In English, examples of such restrictions include: , as in sing, occurs only at the end of a syllable, never at the beginning (in many other languages, such as Māori, Swahili, Tagalog, and Thai, can appear word-initially). occurs only before vowels and at the beginning of a syllable, never at the end (a few languages, such as Arabic, or Romanian allow syllable-finally). In non-rhotic dialects, can only occur immediately before a vowel, never before a consonant. and occur only before a vowel, never at the end of a syllable (except in interpretations where a word like boy is analyzed as ). Some phonotactic restrictions can alternatively be analyzed as cases of neutralization. See Neutralization and archiphonemes below, particularly the example of the occurrence of the three English nasals before stops. Biuniqueness Biuniqueness is a requirement of classic structuralist phonemics. It means that a given phone, wherever it occurs, must unambiguously be assigned to one and only one phoneme. In other words, the mapping between phones and phonemes is required to be many-to-one rather than many-to-many. The notion of biuniqueness was controversial among some pre-generative linguists and was prominently challenged by Morris Halle and Noam Chomsky in the late 1950s and early 1960s. An example of the problems arising from the biuniqueness requirement is provided by the phenomenon of flapping in North American English. This may cause either or (in the appropriate environments) to be realized with the phone (an alveolar flap). For example, the same flap sound may be heard in the words hitting and bidding, although it is intended to realize the phoneme in the first word and in the second. This appears to contradict biuniqueness. For further discussion of such cases, see the next section. Neutralization and archiphonemes Phonemes that are contrastive in certain environments may not be contrastive in all environments. In the environments where they do not contrast, the contrast is said to be neutralized. In these positions it may become less clear which phoneme a given phone represents. Absolute neutralization is a phenomenon in which a segment of the underlying representation is not realized in any of its phonetic representations (surface forms).

The sounds and are thus different phonemes in Hindustani but are not distinct phonemes in English. As can be seen in those examples, phonemes, rather than phones, are the features of speech that are typically reflected (more or less imperfectly) in a writing system. Overview In the context of spoken languages, a phone is an unanalyzed sound of a language. A phone is a speech segment that possesses distinct physical or perceptual properties and serves as the basic unit of phonetic speech analysis. Phones are generally either vowels or consonants. A phonetic transcription (based on phones) is enclosed within square brackets (), rather than the slashes () of a phonemic transcription, (based on phonemes). Phones (and often also phonemes) are commonly represented by using symbols of the International Phonetic Alphabet (IPA). For example, the English word spin consists of four phones, , , and and so the | phonemes in English.

amount of movement by females occurring between groups. He proposed four categories: Female transfer systems – females move away from the group in which they were born. Females of a group will not be closely related whereas males will have remained with their natal groups, and this close association may be influential in social behavior. The groups formed are generally quite small. This organization can be seen in chimpanzees, where the males, who are typically related, will cooperate in defense of the group's territory. Evidence of this social system has also been found among Neanderthal remains in Spain and in remains of Australopithecus and Paranthropus robustus groups in southern Africa. Among New World Monkeys, spider monkeys and muriquis use this system. Male transfer systems – while the females remain in their natal groups, the males will emigrate as adolescents. Polygynous and multi-male societies are classed in this category. Group sizes are usually larger. This system is common among the ring-tailed lemur, capuchin monkeys and cercopithecine monkeys. Monogamous species – a male–female bond, sometimes accompanied by a juvenile offspring. There is shared responsibility of parental care and territorial defense. The offspring leaves the parents' territory during adolescence. Gibbons essentially use this system, although "monogamy" in this context does not necessarily mean absolute sexual fidelity. These species do not live in larger groups. Solitary species – often males who defend territories that include the home ranges of several females. This type of organization is found in the prosimians such as the slow loris. Orangutans do not defend their territory but effectively have this organization. Other systems are known to occur as well. For example, with howler monkeys and gorillas both the males and females typically transfer from their natal group on reaching sexual maturity, resulting in groups in which neither the males nor females are typically related. Some prosimians, colobine monkeys and callitrichid monkeys also use this system. The transfer of females or males from their native group is likely an adaptation for avoiding inbreeding. An analysis of breeding records of captive primate colonies representing numerous different species indicates that the infant mortality of inbred young is generally higher than that of non-inbred young. This effect of inbreeding on infant mortality is probably largely a result of increased expression of deleterious recessive alleles (see Inbreeding depression). Primatologist Jane Goodall, who studied in the Gombe Stream National Park, noted fission-fusion societies in chimpanzees. There is fission when the main group splits up to forage during the day, then fusion when the group returns at night to sleep as a group. This social structure can also be observed in the hamadryas baboon, spider monkeys and the bonobo. The gelada has a similar social structure in which many smaller groups come together to form temporary herds of up to 600 monkeys. Humans also form fission-fusion societies. In hunter-gatherer societies, humans form groups which are made up of several individuals that may split up to obtain different resources. These social systems are affected by three main ecological factors: distribution of resources, group size, and predation. Within a social group there is a balance between cooperation and competition. Cooperative behaviors in many primates species include social grooming (removing skin parasites and cleaning wounds), food sharing, and collective defense against predators or of a territory. Aggressive behaviors often signal competition for food, sleeping sites or mates. Aggression is also used in establishing dominance hierarchies. Interspecific associations Several species of primates are known to associate in the wild. Some of these associations have been extensively studied. In the Tai Forest of Africa several species coordinate anti-predator behavior. These include the Diana monkey, Campbell's mona monkey, lesser spot-nosed monkey, western red colobus, king colobus (western black and white colobus), and sooty mangabey, which coordinate anti-predator alarm calls. Among the predators of these monkeys is the common chimpanzee. The red-tailed monkey associates with several species, including the western red colobus, blue monkey, Wolf's mona monkey, mantled guereza, black crested mangabey and Allen's swamp monkey. Several of these species are preyed upon by the common chimpanzee. In South America, squirrel monkeys associate with capuchin monkeys. This may have more to do with foraging benefits to the squirrel monkeys than anti-predation benefits. Communication Lemurs, lorises, tarsiers, and New World monkeys rely on olfactory signals for many aspects of social and reproductive behavior. Specialized glands are used to mark territories with pheromones, which are detected by the vomeronasal organ; this process forms a large part of the communication behavior of these primates. In Old World monkeys and apes this ability is mostly vestigial, having regressed as trichromatic eyes evolved to become the main sensory organ. Primates also use vocalizations, gestures, and facial expressions to convey psychological state. Facial musculature is very developed in primates, particularly in monkeys and apes, allowing for complex facial communication. Like humans, chimpanzees can distinguish the faces of familiar and unfamiliar individuals. Hand and arm gestures are also important forms of communication for great apes and a single gesture can have multiple functions. The Philippine tarsier, has a high-frequency limit of auditory sensitivity of approximately 91 kHz with a dominant frequency of 70 kHz. Such values are among the highest recorded for any terrestrial mammal, and a relatively extreme example of ultrasonic communication. For Philippine tarsiers, ultrasonic vocalizations might represent a private channel of communication that subverts detection by predators, prey and competitors, enhances energetic efficiency, or improves detection against low-frequency background noise. Male howler monkeys are among the loudest land mammals and their roars can be heard up to . Roars are produced by modified larynx and enlarged hyoid bone which contains an air sac. These calls are thought to relate to intergroup spacing and territorial protection as well as possibly mate-guarding. The vervet monkey gives a distinct alarm call for each of at least four different predators, and the reactions of other monkeys vary according to the call. For example, if an alarm call signals a python, the monkeys climb into the trees, whereas the eagle alarm causes monkeys to seek a hiding place on the ground. Many non-human primates have the vocal anatomy to produce human speech but lack the proper brain wiring. Vowel-like vocal patterns have been recorded in baboons which has implications for the origin of speech in humans. The time range for the evolution of human language and/or its anatomical prerequisites extends, at least in principle, from the phylogenetic divergence of Homo (2.3 to 2.4 million years ago) from Pan (5 to 6 million years ago) to the emergence of full behavioral modernity some 50,000–150,000 years ago. Few dispute that Australopithecus probably lacked vocal communication significantly more sophisticated than that of great apes in general. Life history Primates have slower rates of development than other mammals. All primate infants are breastfed by their mothers (with the exception of some human cultures and various zoo raised primates which are fed formula) and rely on them for grooming and transportation. In some species, infants are protected and transported by males in the group, particularly males who may be their fathers. Other relatives of the infant, such as siblings and aunts, may participate in its care as well. Most primate mothers cease ovulation while breastfeeding an infant; once the infant is weaned the mother can reproduce again. This often leads to weaning conflict with infants who attempt to continue breastfeeding. Infanticide is common in polygynous species such as gray langurs and gorillas. Adult males may kill dependent offspring that are not theirs so the female will return to estrus and thus they can sire offspring of their own. Social monogamy in some species may have evolved to combat this behavior. Promiscuity may also lessen the risk of infanticide since paternity becomes uncertain. Primates have a longer juvenile period between weaning and sexual maturity than other mammals of similar size. Some primates such as galagos and new world monkeys use tree-holes for nesting, and park juveniles in leafy patches while foraging. Other primates follow a strategy of "riding", i.e. carrying individuals on the body while feeding. Adults may construct or use nesting sites, sometimes accompanied by juveniles, for the purpose of resting, a behavior which has developed secondarily in the great apes. During the juvenile period, primates are more susceptible than adults to predation and starvation; they gain experience in feeding and avoiding predators during this time. They learn social and fighting skills, often through playing. Primates, especially females, have longer lifespans than other similarly sized mammals, this may be partially due to their slower metabolisms. Late in life, female catarrhine primates appear to undergo a cessation of reproductive function known as menopause; other groups are less studied. Diet and feeding Primates exploit a variety of food sources. It has been said that many characteristics of modern primates, including humans, derive from an early ancestor's practice of taking most of its food from the tropical canopy. Most primates include fruit in their diets to obtain easily digested nutrients including carbohydrates and lipids for energy. Primates in the suborder Strepsirrhini (non-tarsier prosimians) are able to synthesize vitamin C, like most other mammals, while primates of the suborder Haplorrhini (tarsiers, monkeys and apes) have lost this ability, and require the vitamin in their diet. Many primates have anatomical specializations that enable them to exploit particular foods, such as fruit, leaves, gum or insects. For example, leaf eaters such as howler monkeys, black-and-white colobuses and sportive lemurs have extended digestive tracts which enable them to absorb nutrients from leaves that can be difficult to digest. Marmosets, which are gum eaters, have strong incisor teeth, enabling them to open tree bark to get to the gum, and claws rather than nails, enabling them to cling to trees while feeding. The aye-aye combines rodent-like teeth with a long, thin middle finger to fill the same ecological niche as a woodpecker. It taps on trees to find insect larvae, then gnaws holes in the wood and inserts its elongated middle finger to pull the larvae out. Some species have additional specializations. For example, the grey-cheeked mangabey has thick enamel on its teeth, enabling it to open hard fruits and seeds that other monkeys cannot. The gelada is the only primate species that feeds primarily on grass. Hunting Tarsiers are the only extant obligate carnivorous primates, exclusively eating insects, crustaceans, small vertebrates and snakes (including venomous species). Capuchin monkeys can exploit many different types of plant matter, including fruit, leaves, flowers, buds, nectar and seeds, but also eat insects and other invertebrates, bird eggs, and small vertebrates such as birds, lizards, squirrels and bats. The common chimpanzee eats an omnivorous frugivorous diet. It prefers fruit above all other food items and even seeks out and eats them when they are not abundant. It also eats leaves and leaf buds, seeds, blossoms, stems, pith, bark and resin. Insects and meat make up a small proportion of their diet, estimated as 2%. The meat consumption includes predation on other primate species, such as the western red colobus monkey. The bonobo is an omnivorous frugivore – the majority of its diet is fruit, but it supplements this with leaves, meat from small vertebrates, such as anomalures, flying squirrels and duikers, and invertebrates. In some instances, bonobos have been shown to consume lower-order primates. Until the development of agriculture approximately 10,000 years ago, Homo sapiens employed a hunter-gatherer method as their sole means of food collection. This involved combining stationary food sources (such as fruits, grains, tubers, and mushrooms, insect larvae and aquatic mollusks) with wild game, which must be hunted and killed in order to be consumed. It has been proposed that humans have used fire to prepare and cook food since the time of Homo erectus. Around ten thousand years ago, humans developed agriculture, which substantially altered their diet. This change in diet may also have altered human biology; with the spread of dairy farming providing a new and rich source of food, leading to the evolution of the ability to digest lactose in some adults. As prey Predators of primates include various species of carnivorans, birds of prey, reptiles, and other primates. Even gorillas have been recorded as prey. Predators of primates have diverse hunting strategies and as such, primates have evolved several different antipredator adaptations including crypsis, alarm calls and mobbing. Several species have separate alarm calls for different predators such as air-borne or ground-dwelling predators. Predation may have shaped group size in primates as species exposed to higher predation pressures appear to live in larger groups. Intelligence and cognition Primates have advanced cognitive abilities: some make tools and use them to acquire food and for social displays; some can perform tasks requiring cooperation, influence and rank; they are status conscious, manipulative and capable of deception; they can recognise kin and conspecifics; and they can learn to use symbols and understand aspects of human language including some relational syntax and concepts of number and numerical sequence. Research in primate cognition explores problem solving, memory, social interaction, a theory of mind, and numerical, spatial, and abstract concepts. Comparative studies show a trend towards higher intelligence going from prosimians to New World monkeys to Old World monkeys, and significantly higher average cognitive abilities in the great apes. However, there is a great deal of variation in each group (e.g., among New World monkeys, both spider and capuchin monkeys have scored highly by some measures), as well as in the results of different studies. Tool use and manufacture In 1960, Jane Goodall observed a chimpanzee poking pieces of grass into a termite mound and then raising the grass to his mouth. After he left, Goodall approached the mound and repeated the behaviour because she was unsure what the chimpanzee was doing. She found that the termites bit onto the grass with their jaws. The chimpanzee had been using the grass as a tool to "fish" or "dip" for termites. There are more limited reports of the closely related bonobo using tools in the wild; it has been claimed they rarely use tools in the wild although they use tools as readily as chimpanzees when in captivity. It has been reported that females, both chimpanzee and bonobo, use tools more avidly than males. Orangutans in Borneo scoop catfish out of small ponds. Anthropologist Anne Russon saw several animals on these forested islands learn on their own to jab at catfish with sticks, so that the panicked prey would flop out of ponds and into the orangutan's waiting hands There are few reports of gorillas using tools in the wild. An adult female western lowland gorilla used a branch as a walking stick apparently to test water depth and to aid her in crossing a pool of water. Another adult female used a detached trunk from a small shrub as a stabilizer during food gathering, and another used a log as a bridge. The first direct observation of a non-ape primate using a tool in a wild environment occurred in 1988. Primatologist Sue Boinski watched an adult male white-faced capuchin beat a fer-de-lance snake to death with a dead branch. The black-striped capuchin was the first non-ape primate for which routine tool use was documented in the wild; individuals were observed cracking nuts by placing them on a stone anvil and hitting them with another large stone. In Thailand and Myanmar, crab-eating macaques use stone tools to open nuts, oysters and other bivalves, and various types of sea snails. Chacma baboons use stones as weapons; stoning by these baboons is done from the rocky walls of the canyon where they sleep and retreat to when they are threatened. Stones are lifted with one hand and dropped over the side whereupon they tumble down the side of the cliff or fall directly to the canyon floor. Although they have not been observed to use tools in the wild, lemurs in controlled settings have been shown to be capable of understanding the functional properties of the objects they had been trained to use as tools, performing as well as tool-using haplorhines. Soon after her initial discovery of tool use, Goodall observed other chimpanzees picking up leafy twigs, stripping off the leaves and using the stems to fish for insects. This change of a leafy twig into a tool was a major discovery. Prior to this, scientists thought that only humans manufactured and used tools, and that this ability was what separated humans from other animals. Chimpanzees have also been observed making "sponges" out of leaves and moss that suck up water. Sumatran orangutans have been observed making and using tools. They will break off a tree branch that is about 30 cm long, snap off the twigs, fray one end and then use the stick to dig in tree holes for termites. In the wild, mandrills have been observed to clean their ears with modified tools. Scientists filmed a large male mandrill at Chester Zoo (UK) stripping down a twig, apparently to make it narrower, and then using the modified stick to scrape dirt from underneath its toenails. Captive gorillas have made a variety of tools. Ecology Non-human primates primarily live in the tropical latitudes of Africa, Asia, and the Americas. Species that live outside of the tropics; include the Japanese macaque which lives in the Japanese islands of Honshū and Hokkaido; the Barbary macaque which lives in North Africa and several species of langur which live in China. Primates tend to live in tropical rainforests but are also found in temperate forests, savannas, deserts, mountains and coastal areas. The number of primate species within tropical areas has been shown to be positively correlated to the amount of rainfall and the amount of rain forest area. Accounting for 25% to 40% of the fruit-eating animals (by weight) within tropical rainforests, primates play an important ecological role by dispersing seeds of many tree species. Primate habitats span a range of altitudes: the black snub-nosed monkey has been found living in the Hengduan Mountains at altitudes of 4,700 meters (15,400 ft), the mountain gorilla can be found at 4,200 meters (13,200 ft) crossing the Virunga Mountains, and the gelada has been found at elevations of up to in the Ethiopian Highlands. Some species interact with aquatic environments and may swim or even dive, including the proboscis monkey, De Brazza's monkey and Allen's swamp monkey. Some primates, such as the rhesus macaque and gray langurs, can exploit human-modified environments and even live in cities. Interactions between humans and other primates Disease transmission Close interactions between humans and non-human primates (NHPs) can create pathways for the transmission of zoonotic diseases. Viruses such as Herpesviridae (most notably Herpes B Virus), Poxviridae, measles, ebola, rabies, the Marburg virus and viral hepatitis can be transmitted to humans; in some cases the viruses produce potentially fatal diseases in both humans and non-human primates. Legal and social status Only humans are recognized as persons and protected in law by the United Nations Universal Declaration of Human Rights. The legal status of NHPs, on the other hand, is the subject of much debate, with organizations such as the Great Ape Project (GAP) campaigning to award at least some of them legal rights. In June 2008, Spain became the first country in the world to recognize the rights of some NHPs, when its parliament's cross-party environmental committee urged the country to comply with GAP's recommendations, which are that chimpanzees, bonobos, orangutans, and gorillas are not to be used for animal experiments. Many species of NHP are kept as pets by humans, the Allied Effort to Save Other Primates (AESOP) estimates that around 15,000 NHPs live as exotic pets in the United States. The expanding Chinese middle class has increased demand for NHPs as exotic pets in recent years. Although NHP import for the pet trade was banned in the U.S. in 1975, smuggling still occurs along the United States – Mexico border, with prices ranging from US$3000 for monkeys to $30,000 for apes. Primates are used as model organisms in laboratories and have been used in space missions. They serve as service animals for disabled humans. Capuchin monkeys can be trained to assist quadriplegic humans; their intelligence, memory, and manual dexterity make them ideal helpers. NHPs are kept in zoos around the globe. Historically, zoos were primarily a form of entertainment, but more recently have shifted their focus towards conservation, education and research. GAP does not insist that all NHPs should be released from zoos, primarily because captive-born primates lack the knowledge and experience to survive in the wild if released. Role in scientific research Thousands of non-human primates are used around the world in research because of their psychological and physiological similarity to humans. In particular, the brains and eyes of NHPs more closely parallel human anatomy than those of any other animals. NHPs are commonly used in preclinical trials, neuroscience, ophthalmology studies, and toxicity studies. Rhesus macaques are often used, as are other macaques, African green monkeys, chimpanzees, baboons, squirrel monkeys, and marmosets, both wild-caught and purpose-bred. In 2005, GAP reported that 1,280 of the 3,100 NHPs living in captivity in the United States were used for experiments. In 2004, the European Union used around 10,000 NHPs in such experiments; in 2005 in Great Britain, 4,652 experiments were conducted on 3,115 NHPs. Governments of many nations have strict care requirements of NHPs kept in captivity. In the US, federal guidelines extensively regulate aspects of NHP housing, feeding, enrichment, and breeding. European groups such as the European Coalition to End Animal Experiments are seeking a ban on all NHP use in experiments as part of the European Union's review of animal testing legislation. Extinction threats The International Union for Conservation of Nature (IUCN) lists more than a third of primates as critically endangered or vulnerable. | can only be dichromatic, while females can be either dichromatic or trichromatic. Color vision in strepsirrhines is not as well understood; however, research indicates a range of color vision similar to that found in platyrrhines. Like catarrhines, howler monkeys (a family of platyrrhines) show routine trichromatism that has been traced to an evolutionarily recent gene duplication. Howler monkeys are one of the most specialized leaf-eaters of the New World monkeys; fruits are not a major part of their diets, and the type of leaves they prefer to consume (young, nutritive, and digestible) are detectable only by a red-green signal. Field work exploring the dietary preferences of howler monkeys suggests that routine trichromaticism was selected by environment. Behavior Social systems Richard Wrangham stated that social systems of primates are best classified by the amount of movement by females occurring between groups. He proposed four categories: Female transfer systems – females move away from the group in which they were born. Females of a group will not be closely related whereas males will have remained with their natal groups, and this close association may be influential in social behavior. The groups formed are generally quite small. This organization can be seen in chimpanzees, where the males, who are typically related, will cooperate in defense of the group's territory. Evidence of this social system has also been found among Neanderthal remains in Spain and in remains of Australopithecus and Paranthropus robustus groups in southern Africa. Among New World Monkeys, spider monkeys and muriquis use this system. Male transfer systems – while the females remain in their natal groups, the males will emigrate as adolescents. Polygynous and multi-male societies are classed in this category. Group sizes are usually larger. This system is common among the ring-tailed lemur, capuchin monkeys and cercopithecine monkeys. Monogamous species – a male–female bond, sometimes accompanied by a juvenile offspring. There is shared responsibility of parental care and territorial defense. The offspring leaves the parents' territory during adolescence. Gibbons essentially use this system, although "monogamy" in this context does not necessarily mean absolute sexual fidelity.

After he left, Goodall approached the mound and repeated the behaviour because she was unsure what the chimpanzee was doing. She found that the termites bit onto the grass with their jaws. The chimpanzee had been using the grass as a tool to "fish" or "dip" for termites. There are more limited reports of the closely related bonobo using tools in the wild; it has been claimed they rarely use tools in the wild although they use tools as readily as chimpanzees when in captivity. It has been reported that females, both chimpanzee and bonobo, use tools more avidly than males. Orangutans in Borneo scoop catfish out of small ponds. Anthropologist Anne Russon saw several animals on these forested islands learn on their own to jab at catfish with sticks, so that the panicked prey would flop out of ponds and into the orangutan's waiting hands There are few reports of gorillas using tools in the wild. An adult female western lowland gorilla used a branch as a walking stick apparently to test water depth and to aid her in crossing a pool of water. Another adult female used a detached trunk from a small shrub as a stabilizer during food gathering, and another used a log as a bridge. The first direct observation of a non-ape primate using a tool in a wild environment occurred in 1988. Primatologist Sue Boinski watched an adult male white-faced capuchin beat a fer-de-lance snake to death with a dead branch. The black-striped capuchin was the first non-ape primate for which routine tool use was documented in the wild; individuals were observed cracking nuts by placing them on a stone anvil and hitting them with another large stone. In Thailand and Myanmar, crab-eating macaques use stone tools to open nuts, oysters and other bivalves, and various types of sea snails. Chacma baboons use stones as weapons; stoning by these baboons is done from the rocky walls of the canyon where they sleep and retreat to when they are threatened. Stones are lifted with one hand and dropped over the side whereupon they tumble down the side of the cliff or fall directly to the canyon floor. Although they have not been observed to use tools in the wild, lemurs in controlled settings have been shown to be capable of understanding the functional properties of the objects they had been trained to use as tools, performing as well as tool-using haplorhines. Soon after her initial discovery of tool use, Goodall observed other chimpanzees picking up leafy twigs, stripping off the leaves and using the stems to fish for insects. This change of a leafy twig into a tool was a major discovery. Prior to this, scientists thought that only humans manufactured and used tools, and that this ability was what separated humans from other animals. Chimpanzees have also been observed making "sponges" out of leaves and moss that suck up water. Sumatran orangutans have been observed making and using tools. They will break off a tree branch that is about 30 cm long, snap off the twigs, fray one end and then use the stick to dig in tree holes for termites. In the wild, mandrills have been observed to clean their ears with modified tools. Scientists filmed a large male mandrill at Chester Zoo (UK) stripping down a twig, apparently to make it narrower, and then using the modified stick to scrape dirt from underneath its toenails. Captive gorillas have made a variety of tools. Ecology Non-human primates primarily live in the tropical latitudes of Africa, Asia, and the Americas. Species that live outside of the tropics; include the Japanese macaque which lives in the Japanese islands of Honshū and Hokkaido; the Barbary macaque which lives in North Africa and several species of langur which live in China. Primates tend to live in tropical rainforests but are also found in temperate forests, savannas, deserts, mountains and coastal areas. The number of primate species within tropical areas has been shown to be positively correlated to the amount of rainfall and the amount of rain forest area. Accounting for 25% to 40% of the fruit-eating animals (by weight) within tropical rainforests, primates play an important ecological role by dispersing seeds of many tree species. Primate habitats span a range of altitudes: the black snub-nosed monkey has been found living in the Hengduan Mountains at altitudes of 4,700 meters (15,400 ft), the mountain gorilla can be found at 4,200 meters (13,200 ft) crossing the Virunga Mountains, and the gelada has been found at elevations of up to in the Ethiopian Highlands. Some species interact with aquatic environments and may swim or even dive, including the proboscis monkey, De Brazza's monkey and Allen's swamp monkey. Some primates, such as the rhesus macaque and gray langurs, can exploit human-modified environments and even live in cities. Interactions between humans and other primates Disease transmission Close interactions between humans and non-human primates (NHPs) can create pathways for the transmission of zoonotic diseases. Viruses such as Herpesviridae (most notably Herpes B Virus), Poxviridae, measles, ebola, rabies, the Marburg virus and viral hepatitis can be transmitted to humans; in some cases the viruses produce potentially fatal diseases in both humans and non-human primates. Legal and social status Only humans are recognized as persons and protected in law by the United Nations Universal Declaration of Human Rights. The legal status of NHPs, on the other hand, is the subject of much debate, with organizations such as the Great Ape Project (GAP) campaigning to award at least some of them legal rights. In June 2008, Spain became the first country in the world to recognize the rights of some NHPs, when its parliament's cross-party environmental committee urged the country to comply with GAP's recommendations, which are that chimpanzees, bonobos, orangutans, and gorillas are not to be used for animal experiments. Many species of NHP are kept as pets by humans, the Allied Effort to Save Other Primates (AESOP) estimates that around 15,000 NHPs live as exotic pets in the United States. The expanding Chinese middle class has increased demand for NHPs as exotic pets in recent years. Although NHP import for the pet trade was banned in the U.S. in 1975, smuggling still occurs along the United States – Mexico border, with prices ranging from US$3000 for monkeys to $30,000 for apes. Primates are used as model organisms in laboratories and have been used in space missions. They serve as service animals for disabled humans. Capuchin monkeys can be trained to assist quadriplegic humans; their intelligence, memory, and manual dexterity make them ideal helpers. NHPs are kept in zoos around the globe. Historically, zoos were primarily a form of entertainment, but more recently have shifted their focus towards conservation, education and research. GAP does not insist that all NHPs should be released from zoos, primarily because captive-born primates lack the knowledge and experience to survive in the wild if released. Role in scientific research Thousands of non-human primates are used around the world in research because of their psychological and physiological similarity to humans. In particular, the brains and eyes of NHPs more closely parallel human anatomy than those of any other animals. NHPs are commonly used in preclinical trials, neuroscience, ophthalmology studies, and toxicity studies. Rhesus macaques are often used, as are other macaques, African green monkeys, chimpanzees, baboons, squirrel monkeys, and marmosets, both wild-caught and purpose-bred. In 2005, GAP reported that 1,280 of the 3,100 NHPs living in captivity in the United States were used for experiments. In 2004, the European Union used around 10,000 NHPs in such experiments; in 2005 in Great Britain, 4,652 experiments were conducted on 3,115 NHPs. Governments of many nations have strict care requirements of NHPs kept in captivity. In the US, federal guidelines extensively regulate aspects of NHP housing, feeding, enrichment, and breeding. European groups such as the European Coalition to End Animal Experiments are seeking a ban on all NHP use in experiments as part of the European Union's review of animal testing legislation. Extinction threats The International Union for Conservation of Nature (IUCN) lists more than a third of primates as critically endangered or vulnerable. About 60% of primate species are threatened with extinction, including: 87% of species in Madagascar, 73% in Asia, 37% in Africa, and 36% in South and Central America. Additionally, 75% of primate species have decreasing populations. Trade is regulated, as all species are listed by CITES in Appendix II, except 50 species and subspecies listed in Appendix I, which gain full protection from trade. Common threats to primate species include deforestation, forest fragmentation, monkey drives (resulting from primate crop raiding), and primate hunting for use in medicines, as pets, and for food. Large-scale tropical forest clearing is widely regarded as the process that most threatens primates. More than 90% of primate species occur in tropical forests. The main cause of forest loss is clearing for agriculture, although commercial logging, subsistence harvesting of timber, mining, and dam construction also contribute to tropical forest destruction. In Indonesia large areas of lowland forest have been cleared to increase palm oil production, and one analysis of satellite imagery concluded that during 1998 and 1999 there was a loss of 1,000 Sumatran orangutans per year in the Leuser Ecosystem alone. Primates with a large body size (over 5 kg) are at increased extinction risk due to their greater profitability to poachers compared to smaller primates. They reach sexual maturity later and have a longer period between births. Populations therefore recover more slowly after being depleted by poaching or the pet trade. Data for some African cities show that half of all protein consumed in urban areas comes from the bushmeat trade. Endangered primates such as guenons and the drill are hunted at levels that far exceed sustainable levels. This is due to their large body size, ease of transport and profitability per animal. As farming encroaches on forest habitats, primates feed on the crops, causing the farmers large economic losses. Primate crop raiding gives locals a negative impression of primates, hindering conservation efforts. Madagascar, home to five endemic primate families, has experienced the greatest extinction of the recent past; since human settlement 1,500 years ago, at least eight classes and fifteen of the larger species have become extinct due to hunting and habitat destruction. Among the primates |
different theories and hypotheses regarding early state formation that seek generalizations to explain why the state developed in some places but not others. Other scholars believe that generalizations are unhelpful and that each case of early state formation should be treated on its own. Voluntary theories contend that diverse groups of people came together to form states as a result of some shared rational interest. The theories largely focus on the development of agriculture, and the population and organizational pressure that followed and resulted in state formation. One of the most prominent theories of early and primary state formation is the hydraulic hypothesis, which contends that the state was a result of the need to build and maintain large-scale irrigation projects. Conflict theories of state formation regard conflict and dominance of some population over another population as key to the formation of states. In contrast with voluntary theories, these arguments believe that people do not voluntarily agree to create a state to maximize benefits, but that states form due to some form of oppression by one group over others. Some theories in turn argue that warfare was critical for state formation. Ancient history The first states of sorts were those of early dynastic Sumer and early dynastic Egypt, which arose from the Uruk period and Predynastic Egypt respectively around approximately 3000 BCE. Early dynastic Egypt was based around the Nile River in the north-east of Africa, the kingdom's boundaries being based around the Nile and stretching to areas where oases existed. Early dynastic Sumer was located in southern Mesopotamia with its borders extending from the Persian Gulf to parts of the Euphrates and Tigris rivers. Although state-forms existed before the rise of the Ancient Greek empire, the Greeks were the first people known to have explicitly formulated a political philosophy of the state, and to have rationally analyzed political institutions. Prior to this, states were described and justified in terms of religious myths. Several important political innovations of classical antiquity came from the Greek city-states (polis) and the Roman Republic. The Greek city-states before the 4th century granted citizenship rights to their free population; in Athens these rights were combined with a directly democratic form of government that was to have a long afterlife in political thought and history. Modern states The Peace of Westphalia (1648) is considered by political scientists to be the beginning of the modern international system, in which external powers should avoid interfering in another country's domestic affairs. The principle of non-interference in other countries' domestic affairs was laid out in the mid-18th century by Swiss jurist Emer de Vattel. States became the primary institutional agents in an interstate system of relations. The Peace of Westphalia is said to have ended attempts to impose supranational authority on European states. The "Westphalian" doctrine of states as independent agents was bolstered by the rise in 19th century thought of nationalism, under which legitimate states were assumed to correspond to nations—groups of people united by language and culture. In Europe, during the 18th century, the classic non-national states were the multinational empires: the Austrian Empire, Kingdom of France, Kingdom of Hungary, the Russian Empire, the Spanish Empire, the Ottoman Empire, and the British Empire. Such empires also existed in Asia, Africa, and the Americas; in the Muslim world, immediately after the death of Muhammad in 632, Caliphates were established, which developed into multi-ethnic trans-national empires. The multinational empire was an absolute monarchy ruled by a king, emperor or sultan. The population belonged to many ethnic groups, and they spoke many languages. The empire was dominated by one ethnic group, and their language was usually the language of public administration. The ruling dynasty was usually, but not always, from that group. Some of the smaller European states were not so ethnically diverse, but were also dynastic states, ruled by a royal house. A few of the smaller states survived, such as the independent principalities of Liechtenstein, Andorra, Monaco, and the republic of San Marino. Most theories see the nation state as a 19th-century European phenomenon, facilitated by developments such as state-mandated education, mass literacy, and mass media. However, historians also note the early emergence of a relatively unified state and identity in Portugal and the Dutch Republic. Scholars such as Steven Weber, David Woodward, Michel Foucault, and Jeremy Black have advanced the hypothesis that the nation state did not arise out of political ingenuity or an unknown undetermined source, nor was it an accident of history or political invention. Rather, the nation state is an inadvertent byproduct of 15th-century intellectual discoveries in political economy, capitalism, mercantilism, political geography, and geography combined with cartography and advances in map-making technologies. Some nation states, such as Germany and Italy, came into existence at least partly as a result of political campaigns by nationalists, during the 19th century. In both cases, the territory was previously divided among other states, some of them very small. Liberal ideas of free trade played a role in German unification, which was preceded by a customs union, the Zollverein. National self-determination was a key aspect of United States President Woodrow Wilson's Fourteen Points, leading to the dissolution of the Austro-Hungarian Empire and the Ottoman Empire after the First World War, while the Russian Empire became the Soviet Union after the Russian Civil War. Decolonization lead to the creation of new nation states in place of multinational empires in the Third World. Globalization Political globalization began in the 20th century through intergovernmental organizations and supranational unions. The League of Nations was founded after World War I, and after World War II it was replaced by the United Nations. Various international treaties have been signed through it. Regional integration has been pursued by the African Union, ASEAN, the European Union, and Mercosur. International political institutions on the international level include the International Criminal Court, the International Monetary Fund, and the World Trade Organization. Political science The study of politics is called political science, or politology. It comprises numerous subfields, including comparative politics, political economy, international relations, political philosophy, public administration, public policy, gender and politics, and political methodology. Furthermore, political science is related to, and draws upon, the fields of economics, law, sociology, history, philosophy, geography, psychology/psychiatry, anthropology, and neurosciences. Comparative politics is the science of comparison and teaching of different types of constitutions, political actors, legislature and associated fields, all of them from an intrastate perspective. International relations deals with the interaction between nation-states as well as intergovernmental and transnational organizations. Political philosophy is more concerned with contributions of various classical and contemporary thinkers and philosophers. Political science is methodologically diverse and appropriates many methods originating in psychology, social research, and cognitive neuroscience. Approaches include positivism, interpretivism, rational choice theory, behavioralism, structuralism, post-structuralism, realism, institutionalism, and pluralism. Political science, as one of the social sciences, uses methods and techniques that relate to the kinds of inquiries sought: primary sources such as historical documents and official records, secondary sources such as scholarly journal articles, survey research, statistical analysis, case studies, experimental research, and model building. Political system The political system defines the process for making official government decisions. It is usually compared to the legal system, economic system, cultural system, and other social systems. According to David Easton, "A political system can be designated as the interactions through which values are authoritatively allocated for a society." Each political system is embedded in a society with its own political culture, and they in turn shape their societies through public policy. The interactions between different political systems are the basis for global politics. Forms of government Forms of government can be classified by several ways. In terms of the structure of power, there are monarchies (including constitutional monarchies) and republics (usually presidential, semi-presidential, or parliamentary). The separation of powers describes the degree of horizontal integration between the legislature, the executive, the judiciary, and other independent institutions. Source of power The source of power determines the difference between democracies, oligarchies, and autocracies. In a democracy, political legitimacy is based on popular sovereignty. Forms of democracy include representative democracy, direct democracy, and demarchy. These are separated by the way decisions are made, whether by elected representatives, referendums, or by citizen juries. Democracies can be either republics or constitutional monarchies. Oligarchy is a power structure where a minority rules. These may be in the form of anocracy, aristocracy, ergatocracy, geniocracy, gerontocracy, kakistocracy, kleptocracy, meritocracy, noocracy, particracy, plutocracy, stratocracy, technocracy, theocracy, or timocracy. Autocracies are either dictatorships (including military dictatorships) or absolute monarchies. Vertical integration In terms of level of vertical integration, political systems can be divided into (from least to most integrated) confederations, federations, and unitary states. A federation (also known as a federal state) is a political entity characterized by a union of partially self-governing provinces, states, or other regions under a central federal government (federalism). In a federation, the self-governing status of the component states, as well as the division of power between them and the central government, is typically constitutionally entrenched and may not be altered by a unilateral decision of either party, the states or the federal political body. Federations were formed first in Switzerland, then in the United States in 1776, in Canada in 1867 and in Germany in 1871 and in 1901, Australia. Compared to a federation, a confederation has less centralized power. State All the above forms of government are variations of the same basic polity, the sovereign state. The state has been defined by Max Weber as a political entity that has monopoly on violence within its territory, while the Montevideo Convention holds that states need to have a defined territory; a permanent population; a government; and a capacity to enter into international relations. A stateless society is a society that is not governed by a state. In stateless societies, there is little concentration of authority; most positions of authority that do exist are very limited in power and are generally not permanently held positions; and social bodies that resolve disputes through predefined rules tend to be small. Stateless societies are highly variable in economic organization and cultural practices. While stateless societies were the norm in human prehistory, few stateless societies exist today; almost the entire global population resides within the jurisdiction of a sovereign state. In some regions nominal state authorities may be very weak and wield little or no actual power. Over the course of history most stateless peoples have been integrated into the state-based societies around them. Some political philosophies consider the state undesirable, and thus consider the formation of a stateless society a goal to be achieved. A central tenet of anarchism is the advocacy of society without states. The type of society sought for varies significantly between anarchist schools of thought, ranging from extreme individualism to complete collectivism. In Marxism, Marx's theory of the state considers that in a post-capitalist society the state, an undesirable institution, would be unnecessary and wither away. A related concept is that of stateless communism, a phrase sometimes used to describe Marx's anticipated post-capitalist society. Constitutions Constitutions are written documents that specify and limit the powers of the different branches of government. Although a constitution is a written document, there is also an unwritten constitution. The unwritten constitution is continually being written by the legislative and judiciary branch of government; this is just one of those cases in which the nature of the circumstances determines the form of government that is most appropriate. England did set the fashion of written constitutions during the Civil War but after the Restoration abandoned them to be taken up later by the American Colonies after their emancipation and then France after the Revolution and the rest of Europe including the European colonies. Constitutions often set out separation of powers, dividing the government into the executive, the legislature, and the judiciary (together referred to as the trias politica), in order to achieve checks and balances within the state. Additional independent branches may also be created, including civil service commissions, election commissions, and supreme audit institutions. Political culture Political culture describes how culture impacts politics. Every political system is embedded in a particular political culture. Lucian Pye's definition is that "Political culture is the set of attitudes, beliefs, and sentiments, which give order and meaning to a political process and which provide the underlying assumptions and rules that govern behavior in the political system". Trust is a major factor in political culture, as its level determines the capacity of the state to function. Postmaterialism is the degree to which a political culture is concerned with issues which are not of immediate physical or material concern, such as human rights and environmentalism. Religion has also an impact on political culture. Political dysfunction Political corruption Political corruption is the use of powers for illegitimate private gain, conducted by government officials or their network contacts. Forms of political corruption include bribery, cronyism, nepotism, and political patronage. Forms of political patronage, in turn, includes clientelism, earmarking, pork barreling, slush funds, and spoils systems; as well as political machines, which is a political system that operates for corrupt ends. When corruption is embedded in political culture, | of conflict," while for Carl Schmitt the essence of politics is the distinction of 'friend' from foe'. This is in direct contrast to the more co-operative views of politics by Aristotle and Crick. However, a more mixed view between these extremes is provided by Irish political scientist Michael Laver, who noted that:Politics is about the characteristic blend of conflict and co-operation that can be found so often in human interactions. Pure conflict is war. Pure co-operation is true love. Politics is a mixture of both. History The history of politics spans human history and is not limited to modern institutions of government. Prehistoric Frans de Waal argued that already chimpanzees engage in politics through "social manipulation to secure and maintain influential positions." Early human forms of social organization—bands and tribes—lacked centralized political structures. These are sometimes referred to as stateless societies. Early states In ancient history, civilizations did not have definite boundaries as states have today, and their borders could be more accurately described as frontiers. Early dynastic Sumer, and early dynastic Egypt were the first civilizations to define their borders. Moreover, up to the 12th century, many people lived in non-state societies. These range from relatively egalitarian bands and tribes to complex and highly stratified chiefdoms. State formation There are a number of different theories and hypotheses regarding early state formation that seek generalizations to explain why the state developed in some places but not others. Other scholars believe that generalizations are unhelpful and that each case of early state formation should be treated on its own. Voluntary theories contend that diverse groups of people came together to form states as a result of some shared rational interest.

Week" at the end of May 1871. Late in the 19th century, Paris hosted two major international expositions: the 1889 Universal Exposition, was held to mark the centennial of the French Revolution and featured the new Eiffel Tower; and the 1900 Universal Exposition, which gave Paris the Pont Alexandre III, the Grand Palais, the Petit Palais and the first Paris Métro line. Paris became the laboratory of Naturalism (Émile Zola) and Symbolism (Charles Baudelaire and Paul Verlaine), and of Impressionism in art (Courbet, Manet, Monet, Renoir). 20th and 21st centuries By 1901, the population of Paris had grown to about 2,715,000. At the beginning of the century, artists from around the world including Pablo Picasso, Modigliani, and Henri Matisse made Paris their home. It was the birthplace of Fauvism, Cubism and abstract art, and authors such as Marcel Proust were exploring new approaches to literature. During the First World War, Paris sometimes found itself on the front line; 600 to 1,000 Paris taxis played a small but highly important symbolic role in transporting 6,000 soldiers to the front line at the First Battle of the Marne. The city was also bombed by Zeppelins and shelled by German long-range guns. In the years after the war, known as Les Années Folles, Paris continued to be a mecca for writers, musicians and artists from around the world, including Ernest Hemingway, Igor Stravinsky, James Joyce, Josephine Baker, Eva Kotchever, Henry Miller, Anaïs Nin, Sidney Bechet Allen Ginsberg and the surrealist Salvador Dalí. In the years after the peace conference, the city was also home to growing numbers of students and activists from French colonies and other Asian and African countries, who later became leaders of their countries, such as Ho Chi Minh, Zhou Enlai and Léopold Sédar Senghor. On 14 June 1940, the German army marched into Paris, which had been declared an "open city". On 16–17 July 1942, following German orders, the French police and gendarmes arrested 12,884 Jews, including 4,115 children, and confined them during five days at the Vel d'Hiv (Vélodrome d'Hiver), from which they were transported by train to the extermination camp at Auschwitz. None of the children came back. On 25 August 1944, the city was liberated by the French 2nd Armoured Division and the 4th Infantry Division of the United States Army. General Charles de Gaulle led a huge and emotional crowd down the Champs Élysées towards Notre Dame de Paris, and made a rousing speech from the Hôtel de Ville. In the 1950s and the 1960s, Paris became one front of the Algerian War for independence; in August 1961, the pro-independence FLN targeted and killed 11 Paris policemen, leading to the imposition of a curfew on Muslims of Algeria (who, at that time, were French citizens). On 17 October 1961, an unauthorised but peaceful protest demonstration of Algerians against the curfew led to violent confrontations between the police and demonstrators, in which at least 40 people were killed, including some thrown into the Seine. The anti-independence Organisation armée secrète (OAS), for their part, carried out a series of bombings in Paris throughout 1961 and 1962. In May 1968, protesting students occupied the Sorbonne and put up barricades in the Latin Quarter. Thousands of Parisian blue-collar workers joined the students, and the movement grew into a two-week general strike. Supporters of the government won the June elections by a large majority. The May 1968 events in France resulted in the break-up of the University of Paris into 13 independent campuses. In 1975, the National Assembly changed the status of Paris to that of other French cities and, on 25 March 1977, Jacques Chirac became the first elected mayor of Paris since 1793. The Tour Maine-Montparnasse, the tallest building in the city at 57 storeys and high, was built between 1969 and 1973. It was highly controversial, and it remains the only building in the centre of the city over 32 storeys high. The population of Paris dropped from 2,850,000 in 1954 to 2,152,000 in 1990, as middle-class families moved to the suburbs. A suburban railway network, the RER (Réseau Express Régional), was built to complement the Métro; the Périphérique expressway encircling the city, was completed in 1973. Most of the postwar's Presidents of the Fifth Republic wanted to leave their own monuments in Paris; President Georges Pompidou started the Centre Georges Pompidou (1977), Valéry Giscard d'Estaing began the Musée d'Orsay (1986); President François Mitterrand, in power for 14 years, built the Opéra Bastille (1985–1989), the new site of the Bibliothèque nationale de France (1996), the Arche de la Défense (1985–1989), and the Louvre Pyramid with its underground courtyard (1983–1989); Jacques Chirac (2006), the Musée du quai Branly. In the early 21st century, the population of Paris began to increase slowly again, as more young people moved into the city. It reached 2.25 million in 2011. In March 2001, Bertrand Delanoë became the first Socialist Mayor of Paris. In 2007, in an effort to reduce car traffic in the city, he introduced the Vélib', a system which rents bicycles for the use of local residents and visitors. Bertrand Delanoë also transformed a section of the highway along the Left Bank of the Seine into an urban promenade and park, the Promenade des Berges de la Seine, which he inaugurated in June 2013. In 2007, President Nicolas Sarkozy launched the Grand Paris project, to integrate Paris more closely with the towns in the region around it. After many modifications, the new area, named the Metropolis of Grand Paris, with a population of 6.7 million, was created on 1 January 2016. In 2011, the City of Paris and the national government approved the plans for the Grand Paris Express, totalling of automated metro lines to connect Paris, the innermost three departments around Paris, airports and high-speed rail (TGV) stations, at an estimated cost of €35 billion. The system is scheduled to be completed by 2030. In January 2015, Al-Qaeda in the Arabian Peninsula claimed attacks across the Paris region. 1.5 million people marched in Paris in a show of solidarity against terrorism and in support of freedom of speech. In November of the same year, terrorist attacks, claimed by ISIL, killed 130 people and injured more than 350. Geography Location Paris is located in northern central France, in a north-bending arc of the river Seine whose crest includes two islands, the Île Saint-Louis and the larger Île de la Cité, which form the oldest part of the city. The river's mouth on the English Channel (La Manche) is about downstream from the city. The city is spread widely on both banks of the river. Overall, the city is relatively flat, and the lowest point is above sea level. Paris has several prominent hills, the highest of which is Montmartre at . Excluding the outlying parks of Bois de Boulogne and Bois de Vincennes, Paris covers an oval measuring about in area, enclosed by the ring road, the Boulevard Périphérique. The city's last major annexation of outlying territories in 1860 not only gave it its modern form but also created the 20 clockwise-spiralling arrondissements (municipal boroughs). From the 1860 area of , the city limits were expanded marginally to in the 1920s. In 1929, the Bois de Boulogne and Bois de Vincennes forest parks were officially annexed to the city, bringing its area to about . The metropolitan area of the city is . Measured from the 'point zero' in front of its Notre-Dame cathedral, Paris by road is southeast of London, south of Calais, southwest of Brussels, north of Marseille, northeast of Nantes, and southeast of Rouen. Climate Paris has a typical Western European oceanic climate (Köppen: Cfb), which is affected by the North Atlantic Current. The overall climate throughout the year is mild and moderately wet. Summer days are usually warm and pleasant with average temperatures between , and a fair amount of sunshine. Each year, however, there are a few days when the temperature rises above . Longer periods of more intense heat sometimes occur, such as the heat wave of 2003 when temperatures exceeded for weeks, reached on some days and rarely cooled down at night. Spring and autumn have, on average, mild days and fresh nights but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons. In winter, sunshine is scarce; days are cool, and nights are cold but generally above freezing with low temperatures around . Light night frosts are however quite common, but the temperature seldom dips below . Snow falls every year, but rarely stays on the ground. The city sometimes sees light snow or flurries with or without accumulation. Paris has an average annual precipitation of , and experiences light rainfall distributed evenly throughout the year. However, the city is known for intermittent, abrupt, heavy showers. The highest recorded temperature was on 25 July 2019, and the lowest was on 10 December 1879. Administration City government For almost all of its long history, except for a few brief periods, Paris was governed directly by representatives of the king, emperor, or president of France. The city was not granted municipal autonomy by the National Assembly until 1974. For all but 14 months from 1794 to 1977, Paris was the only French commune without a mayor, and thus had less autonomy than the smallest village. For most of the time from 1800 to 1977 (except briefly in 1848 and 1870–71), it was directly controlled by the departmental prefect (the prefect of the Seine until 1968, and the prefect of Paris from 1968 to 1977). The first modern elected mayor of Paris was Jacques Chirac, elected 20 March 1977, becoming the city's first mayor since 1871 and only the fourth since 1794. The current mayor is Anne Hidalgo, a socialist, first elected 5 April 2014 and re-elected 28 June 2020. The mayor of Paris is elected indirectly by Paris voters; the voters of each of the city's 20 arrondissements elect members to the Conseil de Paris (Council of Paris), which subsequently elects the mayor. The council is composed of 163 members, with each arrondissement allocated a number of seats dependent upon its population, from 10 members for each of the least-populated arrondissements (1st through 9th) to 34 members for the most populated (the 15th). The council is elected using closed list proportional representation in a two-round system. Party lists winning an absolute majority in the first round – or at least a plurality in the second round – automatically win half the seats of an arrondissement. The remaining half of seats are distributed proportionally to all lists which win at least 5% of the vote using the highest averages method. This ensures that the winning party or coalition always wins a majority of the seats, even if they don't win an absolute majority of the vote. Once elected, the council plays a largely passive role in the city government, primarily because it meets only once a month. The council is divided between a coalition of the left of 91 members, including the socialists, communists, greens, and extreme left; and 71 members for the centre-right, plus a few members from smaller parties. Each of Paris's 20 arrondissements has its own town hall and a directly elected council (conseil d'arrondissement), which, in turn, elects an arrondissement mayor. The council of each arrondissement is composed of members of the Conseil de Paris and also members who serve only on the council of the arrondissement. The number of deputy mayors in each arrondissement varies depending upon its population. There are a total of 20 arrondissement mayors and 120 deputy mayors. The budget of the city for 2018 is 9.5 billion Euros, with an expected deficit of 5.5 billion Euros. 7.9 billion Euros are designated for city administration, and 1.7 billion Euros for investment. The number of city employees increased from 40,000 in 2001 to 55,000 in 2018. The largest part of the investment budget is earmarked for public housing (262 million Euros) and for real estate (142 million Euros). Métropole du Grand Paris The Métropole du Grand Paris, or simply Grand Paris, formally came into existence on 1 January 2016. It is an administrative structure for co-operation between the City of Paris and its nearest suburbs. It includes the City of Paris, plus the communes of the three departments of the inner suburbs (Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne), plus seven communes in the outer suburbs, including Argenteuil in Val d'Oise and Paray-Vieille-Poste in Essonne, which were added to include the major airports of Paris. The Metropole covers and has a population of 6.945 million persons. The new structure is administered by a Metropolitan Council of 210 members, not directly elected, but chosen by the councils of the member Communes. By 2020 its basic competencies will include urban planning, housing and protection of the environment. The first president of the metropolitan council, Patrick Ollier, a Republican and the mayor of the town of Rueil-Malmaison, was elected on 22 January 2016. Though the Metropole has a population of nearly seven million people and accounts for 25 percent of the GDP of France, it has a very small budget: just 65 million Euros, compared with eight billion Euros for the City of Paris. Regional government The Region of Île de France, including Paris and its surrounding communities, is governed by the Regional Council, which has its headquarters in the 7th arrondissement of Paris. It is composed of 209 members representing the different communes within the region. On 15 December 2015, a list of candidates of the Union of the Right, a coalition of centrist and right-wing parties, led by Valérie Pécresse, narrowly won the regional election, defeating a coalition of Socialists and ecologists. The Socialists had governed the region for seventeen years. The regional council has 121 members from the Union of the Right, 66 from the Union of the Left and 22 from the extreme right National Front. National government As the capital of France, Paris is the seat of France's national government. For the executive, the two chief officers each have their own official residences, which also serve as their offices. The President of the French Republic resides at the Élysée Palace in the 8th arrondissement, while the Prime Minister's seat is at the Hôtel Matignon in the 7th arrondissement. Government ministries are located in various parts of the city; many are located in the 7th arrondissement, near the Hôtel Matignon. Both houses of the French Parliament are located on the Rive Gauche. The upper house, the Senate, meets in the Palais du Luxembourg in the 6th arrondissement, while the more important lower house, the National Assembly, meets in the Palais Bourbon in the 7th arrondissement. The President of the Senate, the second-highest public official in France (the President of the Republic being the sole superior), resides in the Petit Luxembourg, a smaller palace annexe to the Palais du Luxembourg. France's highest courts are located in Paris. The Court of Cassation, the highest court in the judicial order, which reviews criminal and civil cases, is located in the Palais de Justice on the Île de la Cité, while the Conseil d'État, which provides legal advice to the executive and acts as the highest court in the administrative order, judging litigation against public bodies, is located in the Palais-Royal in the 1st arrondissement. The Constitutional Council, an advisory body with ultimate authority on the constitutionality of laws and government decrees, also meets in the Montpensier wing of the Palais Royal. Paris and its region host the headquarters of several international organisations including UNESCO, the Organisation for Economic Co-operation and Development, the International Chamber of Commerce, the Paris Club, the European Space Agency, the International Energy Agency, the Organisation internationale de la Francophonie, the European Union Institute for Security Studies, the International Bureau of Weights and Measures, the International Exhibition Bureau, and the International Federation for Human Rights. Following the motto "Only Paris is worthy of Rome; only Rome is worthy of Paris"; the only sister city of Paris is Rome, although Paris has partnership agreements with many other cities around the world. Police force The security of Paris is mainly the responsibility of the Prefecture of Police of Paris, a subdivision of the Ministry of the Interior. It supervises the units of the National Police who patrol the city and the three neighbouring departments. It is also responsible for providing emergency services, including the Paris Fire Brigade. Its headquarters is on Place Louis Lépine on the Île de la Cité. There are 30,200 officers under the prefecture, and a fleet of more than 6,000 vehicles, including police cars, motorcycles, fire trucks, boats and helicopters. The national police has its own special unit for riot control and crowd control and security of public buildings, called the Compagnies Républicaines de Sécurité (CRS), a unit formed in 1944 right after the liberation of France. Vans of CRS agents are frequently seen in the centre of the city when there are demonstrations and public events. The police are supported by the National Gendarmerie, a branch of the French Armed Forces, though their police operations now are supervised by the Ministry of the Interior. The traditional kepis of the gendarmes were replaced in 2002 with caps, and the force modernised, though they still wear kepis for ceremonial occasions. Crime in Paris is similar to that in most large cities. Violent crime is relatively rare in the city centre. Political violence is uncommon, though very large demonstrations may occur in Paris and other French cities simultaneously. These demonstrations, usually managed by a strong police presence, can turn confrontational and escalate into violence. Cityscape Urbanism and architecture Most French rulers since the Middle Ages made a point of leaving their mark on a city that, contrary to many other of the world's capitals, has never been destroyed by catastrophe or war. In modernising its infrastructure through the centuries, Paris has preserved even its earliest history in its street map. At its origin, before the Middle Ages, the city was composed of several islands and sandbanks in a bend of the Seine; of those, two remain today: Île Saint-Louis and the Île de la Cité. A third one is the 1827 artificially created Île aux Cygnes. Modern Paris owes much of its downtown plan and architectural harmony to Napoleon III and his Prefect of the Seine, Baron Haussmann. Between 1853 and 1870 they rebuilt the city centre, created the wide downtown boulevards and squares where the boulevards intersected, imposed standard facades along the boulevards, and required that the facades be built of the distinctive cream-grey "Paris stone". They also built the major parks around the city centre. The high residential population of its city centre also makes it much different from most other western major cities. Paris's urbanism laws have been under strict control since the early 17th century, particularly where street-front alignment, building height and building distribution is concerned. In recent developments, a 1974–2010 building height limitation of was raised to in central areas and in some of Paris's peripheral quarters, yet for some of the city's more central quarters, even older building-height laws still remain in effect. The Tour Montparnasse was both Paris's and France's tallest building since 1973, but this record has been held by the La Défense quarter Tour First tower in Courbevoie since its 2011 construction. Parisian examples of historical architectural styles date back more than a millennium, including the Romanesque church of the Abbey of Saint-Germain-des-Prés (1014–1163), the early Gothic Architecture of the Basilica of Saint-Denis (1144), the Notre Dame Cathedral (1163–1345), the Flamboyant Gothic of Saint Chapelle (1239–1248), the Baroque churches of Saint-Paul-Saint-Louis (1627–1641) and Les Invalides (1670–1708). The 19th century produced the neoclassical church of La Madeleine (1808–1842), the Palais Garnier serving as an opera house (1875), the neo-Byzantine Basilica of Sacré-Cœur (1875–1919), as well as the exuberant Belle Époque modernism of the Eiffel Tower (1889). Striking examples of 20th-century architecture include the Centre Georges Pompidou by Richard Rogers and Renzo Piano (1977), the Cité des Sciences et de l'Industrie by various architects (1986), the Arab World Institute by Jean Nouvel (1987), the Louvre Pyramid by I. M. Pei (1989) and the Opéra Bastille by Carlos Ott (1989). Contemporary architecture includes the Musée du quai Branly – Jacques Chirac by Jean Nouvel (2006), the contemporary art museum of the Louis Vuitton Foundation by Frank Gehry (2014) and the new Tribunal de grande instance de Paris by Renzo Piano (2018). Housing The most expensive residential streets in Paris in 2018 by average price per square metre were Avenue Montaigne (8th arrondissement), at 22,372 euros per square metre; Place Dauphine (1st arrondissement; 20,373 euros) and the Rue de Furstemberg (6th arrondissement) at 18,839 euros per square metre. The total number of residences in the City of Paris in 2011 was , up from a former high of in 2006. Among these, (85.9 percent) were main residences, (6.8 percent) were secondary residences, and the remaining 7.3 percent were empty (down from 9.2 percent in 2006). Sixty-two percent of its buildings date from 1949 and before, 20 percent were built between 1949 and 1974, and only 18 percent of the buildings remaining were built after that date. Two-thirds of the city's 1.3 million residences are studio and two-room apartments. Paris averages 1.9 people per residence, a number that has remained constant since the 1980s, but it is much less than Île-de-France's 2.33 person-per-residence average. Only 33 percent of principal residence Parisians own their habitation (against 47 percent for the entire Île-de-France): the major part of the city's population is a rent-paying one. Social or public housing represented 19.9 percent of the city's total residences in 2017. Its distribution varies widely throughout the city, from 2.6 percent of the housing in the wealthy 7th arrondissement, to 24 percent in the 20th arrondissement, 26 percent in the 14th arrondissement and 39.9 percent in the 19th arrondissement, on the poorer southwest and northern edges of the city. On the night of 8–9 February 2019, during a period of cold weather, a Paris NGO conducted its annual citywide count of homeless persons. They counted 3,641 homeless persons in Paris, of whom twelve percent were women. More than half had been homeless for more than a year. 2,885 were living in the streets or parks, 298 in train and metro stations, and 756 in other forms of temporary shelter. This was an increase of 588 persons since 2018. Paris and its suburbs Aside from the 20th-century addition of the Bois de Boulogne, the Bois de Vincennes and the Paris heliport, Paris's administrative limits have remained unchanged since 1860. A greater administrative Seine department had been governing Paris and its suburbs since its creation in 1790, but the rising suburban population had made it difficult to maintain as a unique entity. To address this problem, the parent "District de la région parisienne" ('district of the Paris region') was reorganised into several new departments from 1968: Paris became a department in itself, and the administration of its suburbs was divided between the three new departments surrounding it. The district of the Paris region was renamed "Île-de-France" in 1977, but this abbreviated "Paris region" name is still commonly used today to describe the Île-de-France, and as a vague reference to the entire Paris agglomeration. Long-intended measures to unite Paris with its suburbs began on 1 January 2016, when the Métropole du Grand Paris came into existence. Paris's disconnect with its suburbs, its lack of suburban transportation, in particular, became all too apparent with the Paris agglomeration's growth. Paul Delouvrier promised to resolve the Paris-suburbs mésentente when he became head of the Paris region in 1961: two of his most ambitious projects for the Region were the construction of five suburban "villes nouvelles" ("new cities") and the RER commuter train network. Many other suburban residential districts (grands ensembles) were built between the 1960s and 1970s to provide a low-cost solution for a rapidly expanding population: These districts were socially mixed at first, but few residents actually owned their homes (the growing economy made these accessible to the middle classes only from the 1970s). Their poor construction quality and their haphazard insertion into existing urban growth contributed to their desertion by those able to move elsewhere and their repopulation by those with more limited possibilities. These areas, quartiers sensibles ("sensitive quarters"), are in northern and eastern Paris, namely around its Goutte d'Or and Belleville neighbourhoods. To the north of the city, they are grouped mainly in the Seine-Saint-Denis department, and to a lesser extreme to the east in the Val-d'Oise department. Other difficult areas are located in the Seine valley, in Évry et Corbeil-Essonnes (Essonne), in Mureaux, Mantes-la-Jolie (Yvelines), and scattered among social housing districts created by Delouvrier's 1961 "ville nouvelle" political initiative. The Paris agglomeration's urban sociology is basically that of 19th-century Paris: its fortuned classes are situated in its west and southwest, and its middle-to-lower classes are in its north and east. The remaining areas are mostly middle-class citizenry dotted with islands of fortuned populations located there due to reasons of historical importance, namely Saint-Maur-des-Fossés to the east and Enghien-les-Bains to the north of Paris. Demographics The official estimated population of the City of Paris was 2,165,423 on 1 January 2022, according to the INSEE, the official French statistical agency. This was a decline of 11,000 from January 2021, and a drop of 65,000 over six years. Despite the drop, Paris remains the most densely-populated city in Europe, with 252 residents per hectare, not counting parks. This drop | that visitors wear masks. The football club Paris Saint-Germain and the rugby union club Stade Français are based in Paris. The 80,000-seat Stade de France, built for the 1998 FIFA World Cup, is located just north of Paris in the neighbouring commune of Saint-Denis. Paris hosts the annual French Open Grand Slam tennis tournament on the red clay of Roland Garros. The city hosted the Olympic Games in 1900, 1924 and will host the 2024 Summer Olympics. The 1938 and 1998 FIFA World Cups, the 2007 Rugby World Cup, as well as the 1960, 1984 and 2016 UEFA European Championships were also held in the city. Every July, the Tour de France bicycle race finishes on the Avenue des Champs-Élysées in Paris. Etymology The ancient oppidum that corresponds to the modern city of Paris was first mentioned in the mid-1st century BC by Julius Caesar as Luteciam Parisiorum ('Lutetia of the Parisii'), and is later attested as Parision in the 5th century AD, then as Paris in 1265. During the Roman period, it was commonly known as Lutetia or Lutecia in Latin, and as Leukotekía in Greek, which is interpreted as either stemming from the Celtic root *lukot- ('mouse'), or from *luto- ('marsh, swamp'), depending on whether the Latin or Greek form is the closest to the original Gaulish name. The name Paris is derived from its early inhabitants, the Parisii (Gaulish: Parisioi), a Gallic tribe from the Iron Age and the Roman period. The meaning of the Gaulish ethnonym remains debated. According to Xavier Delamarre, it may derive from the Celtic root pario- ('cauldron'). Alfred Holder interpreted the name as 'the makers' or 'the commanders', by comparing it to the Welsh peryff ('lord, commander'), both possibly descending from a Proto-Celtic form reconstructed as *kwar-is-io-. Alternatively, Pierre-Yves Lambert proposed to translate Parisii as the 'spear people', by connecting the first element to the Old Irish carr ('spear'), derived from an earlier *kwar-sā. In any case, the city's name is not related to the Paris of Greek mythology. Paris is often referred to as the 'City of Light' (La Ville Lumière), both because of its leading role during the Age of Enlightenment and more literally because Paris was one of the first large European cities to use gas street lighting on a grand scale on its boulevards and monuments. Gas lights were installed on the Place du Carrousel, Rue de Rivoli and Place Vendome in 1829. By 1857, the Grand boulevards were lit. By the 1860s, the boulevards and streets of Paris were illuminated by 56,000 gas lamps. Since the late 19th century, Paris has also been known as Panam(e) () in French slang. Inhabitants are known in English as "Parisians" and in French as Parisiens (). They are also pejoratively called Parigots (). History Origins The Parisii, a sub-tribe of the Celtic Senones, inhabited the Paris area from around the middle of the 3rd century BC. One of the area's major north–south trade routes crossed the Seine on the île de la Cité; this meeting place of land and water trade routes gradually became an important trading centre. The Parisii traded with many river towns (some as far away as the Iberian Peninsula) and minted their own coins for that purpose. The Romans conquered the Paris Basin in 52 BC and began their settlement on Paris's Left Bank. The Roman town was originally called Lutetia (more fully, Lutetia Parisiorum, "Lutetia of the Parisii", modern French Lutèce). It became a prosperous city with a forum, baths, temples, theatres, and an amphitheatre. By the end of the Western Roman Empire, the town was known as Parisius, a Latin name that would later become Paris in French. Christianity was introduced in the middle of the 3rd century AD by Saint Denis, the first Bishop of Paris: according to legend, when he refused to renounce his faith before the Roman occupiers, he was beheaded on the hill which became known as Mons Martyrum (Latin "Hill of Martyrs"), later "Montmartre", from where he walked headless to the north of the city; the place where he fell and was buried became an important religious shrine, the Basilica of Saint-Denis, and many French kings are buried there. Clovis the Frank, the first king of the Merovingian dynasty, made the city his capital from 508. As the Frankish domination of Gaul began, there was a gradual immigration by the Franks to Paris and the Parisian Francien dialects were born. Fortification of the Île de la Cité failed to avert sacking by Vikings in 845, but Paris's strategic importance—with its bridges preventing ships from passing—was established by successful defence in the Siege of Paris (885–886), for which the then Count of Paris (comte de Paris), Odo of France, was elected king of West Francia. From the Capetian dynasty that began with the 987 election of Hugh Capet, Count of Paris and Duke of the Franks (duc des Francs), as king of a unified Francia, Paris gradually became the largest and most prosperous city in France. High and Late Middle Ages to Louis XIV By the end of the 12th century, Paris had become the political, economic, religious, and cultural capital of France. The Palais de la Cité, the royal residence, was located at the western end of the Île de la Cité. In 1163, during the reign of Louis VII, Maurice de Sully, bishop of Paris, undertook the construction of the Notre Dame Cathedral at its eastern extremity. After the marshland between the river Seine and its slower 'dead arm' to its north was filled in from around the 10th century, Paris's cultural centre began to move to the Right Bank. In 1137, a new city marketplace (today's Les Halles) replaced the two smaller ones on the Île de la Cité and Place de Grève (Place de l'Hôtel de Ville). The latter location housed the headquarters of Paris's river trade corporation, an organisation that later became, unofficially (although formally in later years), Paris's first municipal government. In the late 12th century, Philip Augustus extended the Louvre fortress to defend the city against river invasions from the west, gave the city its first walls between 1190 and 1215, rebuilt its bridges to either side of its central island, and paved its main thoroughfares. In 1190, he transformed Paris's former cathedral school into a student-teacher corporation that would become the University of Paris and would draw students from all of Europe. With 200,000 inhabitants in 1328, Paris, then already the capital of France, was the most populous city of Europe. By comparison, London in 1300 had 80,000 inhabitants. During the Hundred Years' War, Paris was occupied by England-friendly Burgundian forces from 1418, before being occupied outright by the English when Henry V of England entered the French capital in 1420; in spite of a 1429 effort by Joan of Arc to liberate the city, it would remain under English occupation until 1436. In the late 16th-century French Wars of Religion, Paris was a stronghold of the Catholic League, the organisers of 24 August 1572 St. Bartholomew's Day massacre in which thousands of French Protestants were killed. The conflicts ended when pretender to the throne Henry IV, after converting to Catholicism to gain entry to the capital, entered the city in 1594 to claim the crown of France. This king made several improvements to the capital during his reign: he completed the construction of Paris's first uncovered, sidewalk-lined bridge, the Pont Neuf, built a Louvre extension connecting it to the Tuileries Palace, and created the first Paris residential square, the Place Royale, now Place des Vosges. In spite of Henry IV's efforts to improve city circulation, the narrowness of Paris's streets was a contributing factor in his assassination near Les Halles marketplace in 1610. During the 17th century, Cardinal Richelieu, chief minister of Louis XIII, was determined to make Paris the most beautiful city in Europe. He built five new bridges, a new chapel for the College of Sorbonne, and a palace for himself, the Palais-Cardinal, which he bequeathed to Louis XIII. After Richelieu's death in 1642, it was renamed the Palais-Royal. Due to the Parisian uprisings during the Fronde civil war, Louis XIV moved his court to a new palace, Versailles, in 1682. Although no longer the capital of France, arts and sciences in the city flourished with the Comédie-Française, the Academy of Painting, and the French Academy of Sciences. To demonstrate that the city was safe from attack, the king had the city walls demolished and replaced with tree-lined boulevards that would become the Grands Boulevards of today. Other marks of his reign were the Collège des Quatre-Nations, the Place Vendôme, the Place des Victoires, and Les Invalides. 18th and 19th centuries Paris grew in population from about 400,000 in 1640 to 650,000 in 1780. A new boulevard, the Champs-Élysées, extended the city west to Étoile, while the working-class neighbourhood of the Faubourg Saint-Antoine on the eastern site of the city grew more and more crowded with poor migrant workers from other regions of France. Paris was the centre of an explosion of philosophic and scientific activity known as the Age of Enlightenment. Diderot and d'Alembert published their Encyclopédie in 1751, and the Montgolfier Brothers launched the first manned flight in a hot-air balloon on 21 November 1783, from the gardens of the Château de la Muette. Paris was the financial capital of continental Europe, the primary European centre of book publishing and fashion and the manufacture of fine furniture and luxury goods. In the summer of 1789, Paris became the centre stage for the French Revolution. On 14 July, a mob seized the arsenal at the Invalides, acquiring thousands of guns, and stormed the Bastille, a symbol of royal authority. The first independent Paris Commune, or city council, met in the Hôtel de Ville and, on 15 July, elected a Mayor, the astronomer Jean Sylvain Bailly. Louis XVI and the royal family were brought to Paris and made prisoners within the Tuileries Palace. In 1793, as the revolution turned more and more radical, the king, queen, and the mayor were guillotined (executed) in the Reign of Terror, along with more than 16,000 others throughout France. The property of the aristocracy and the church was nationalised, and the city's churches were closed, sold or demolished. A succession of revolutionary factions ruled Paris until 9 November 1799 (coup d'état du 18 brumaire), when Napoléon Bonaparte seized power as First Consul. The population of Paris had dropped by 100,000 during the Revolution, but between 1799 and 1815, it surged with 160,000 new residents, reaching 660,000. Napoleon Bonaparte replaced the elected government of Paris with a prefect reporting only to him. He began erecting monuments to military glory, including the Arc de Triomphe, and improved the neglected infrastructure of the city with new fountains, the Canal de l'Ourcq, Père Lachaise Cemetery and the city's first metal bridge, the Pont des Arts. During the Restoration, the bridges and squares of Paris were returned to their pre-Revolution names; the July Revolution in 1830 (commemorated by the July Column on the Place de la Bastille) brought a constitutional monarch, Louis Philippe I, to power. The first railway line to Paris opened in 1837, beginning a new period of massive migration from the provinces to the city. Louis-Philippe was overthrown by a popular uprising in the streets of Paris in 1848. His successor, Napoleon III, alongside the newly appointed prefect of the Seine, Georges-Eugène Haussmann, launched a gigantic public works project to build wide new boulevards, a new opera house, a central market, new aqueducts, sewers and parks, including the Bois de Boulogne and Bois de Vincennes. In 1860, Napoleon III also annexed the surrounding towns and created eight new arrondissements, expanding Paris to its current limits. During the Franco-Prussian War (1870–1871), Paris was besieged by the Prussian Army. After months of blockade, hunger, and then bombardment by the Prussians, the city was forced to surrender on 28 January 1871. On 28 March, a revolutionary government called the Paris Commune seized power in Paris. The Commune held power for two months, until it was harshly suppressed by the French army during the "Bloody Week" at the end of May 1871. Late in the 19th century, Paris hosted two major international expositions: the 1889 Universal Exposition, was held to mark the centennial of the French Revolution and featured the new Eiffel Tower; and the 1900 Universal Exposition, which gave Paris the Pont Alexandre III, the Grand Palais, the Petit Palais and the first Paris Métro line. Paris became the laboratory of Naturalism (Émile Zola) and Symbolism (Charles Baudelaire and Paul Verlaine), and of Impressionism in art (Courbet, Manet, Monet, Renoir). 20th and 21st centuries By 1901, the population of Paris had grown to about 2,715,000. At the beginning of the century, artists from around the world including Pablo Picasso, Modigliani, and Henri Matisse made Paris their home. It was the birthplace of Fauvism, Cubism and abstract art, and authors such as Marcel Proust were exploring new approaches to literature. During the First World War, Paris sometimes found itself on the front line; 600 to 1,000 Paris taxis played a small but highly important symbolic role in transporting 6,000 soldiers to the front line at the First Battle of the Marne. The city was also bombed by Zeppelins and shelled by German long-range guns. In the years after the war, known as Les Années Folles, Paris continued to be a mecca for writers, musicians and artists from around the world, including Ernest Hemingway, Igor Stravinsky, James Joyce, Josephine Baker, Eva Kotchever, Henry Miller, Anaïs Nin, Sidney Bechet Allen Ginsberg and the surrealist Salvador Dalí. In the years after the peace conference, the city was also home to growing numbers of students and activists from French colonies and other Asian and African countries, who later became leaders of their countries, such as Ho Chi Minh, Zhou Enlai and Léopold Sédar Senghor. On 14 June 1940, the German army marched into Paris, which had been declared an "open city". On 16–17 July 1942, following German orders, the French police and gendarmes arrested 12,884 Jews, including 4,115 children, and confined them during five days at the Vel d'Hiv (Vélodrome d'Hiver), from which they were transported by train to the extermination camp at Auschwitz. None of the children came back. On 25 August 1944, the city was liberated by the French 2nd Armoured Division and the 4th Infantry Division of the United States Army. General Charles de Gaulle led a huge and emotional crowd down the Champs Élysées towards Notre Dame de Paris, and made a rousing speech from the Hôtel de Ville. In the 1950s and the 1960s, Paris became one front of the Algerian War for independence; in August 1961, the pro-independence FLN targeted and killed 11 Paris policemen, leading to the imposition of a curfew on Muslims of Algeria (who, at that time, were French citizens). On 17 October 1961, an unauthorised but peaceful protest demonstration of Algerians against the curfew led to violent confrontations between the police and demonstrators, in which at least 40 people were killed, including some thrown into the Seine. The anti-independence Organisation armée secrète (OAS), for their part, carried out a series of bombings in Paris throughout 1961 and 1962. In May 1968, protesting students occupied the Sorbonne and put up barricades in the Latin Quarter. Thousands of Parisian blue-collar workers joined the students, and the movement grew into a two-week general strike. Supporters of the government won the June elections by a large majority. The May 1968 events in France resulted in the break-up of the University of Paris into 13 independent campuses. In 1975, the National Assembly changed the status of Paris to that of other French cities and, on 25 March 1977, Jacques Chirac became the first elected mayor of Paris since 1793. The Tour Maine-Montparnasse, the tallest building in the city at 57 storeys and high, was built between 1969 and 1973. It was highly controversial, and it remains the only building in the centre of the city over 32 storeys high. The population of Paris dropped from 2,850,000 in 1954 to 2,152,000 in 1990, as middle-class families moved to the suburbs. A suburban railway network, the RER (Réseau Express Régional), was built to complement the Métro; the Périphérique expressway encircling the city, was completed in 1973. Most of the postwar's Presidents of the Fifth Republic wanted to leave their own monuments in Paris; President Georges Pompidou started the Centre Georges Pompidou (1977), Valéry Giscard d'Estaing began the Musée d'Orsay (1986); President François Mitterrand, in power for 14 years, built the Opéra Bastille (1985–1989), the new site of the Bibliothèque nationale de France (1996), the Arche de la Défense (1985–1989), and the Louvre Pyramid with its underground courtyard (1983–1989); Jacques Chirac (2006), the Musée du quai Branly. In the early 21st century, the population of Paris began to increase slowly again, as more young people moved into the city. It reached 2.25 million in 2011. In March 2001, Bertrand Delanoë became the first Socialist Mayor of Paris. In 2007, in an effort to reduce car traffic in the city, he introduced the Vélib', a system which rents bicycles for the use of local residents and visitors. Bertrand Delanoë also transformed a section of the highway along the Left Bank of the Seine into an urban promenade and park, the Promenade des Berges de la Seine, which he inaugurated in June 2013. In 2007, President Nicolas Sarkozy launched the Grand Paris project, to integrate Paris more closely with the towns in the region around it. After many modifications, the new area, named the Metropolis of Grand Paris, with a population of 6.7 million, was created on 1 January 2016. In 2011, the City of Paris and the national government approved the plans for the Grand Paris Express, totalling of automated metro lines to connect Paris, the innermost three departments around Paris, airports and high-speed rail (TGV) stations, at an estimated cost of €35 billion. The system is scheduled to be completed by 2030. In January 2015, Al-Qaeda in the Arabian Peninsula claimed attacks across the Paris region. 1.5 million people marched in Paris in a show of solidarity against terrorism and in support of freedom of speech. In November of the same year, terrorist attacks, claimed by ISIL, killed 130 people and injured more than 350. Geography Location Paris is located in northern central France, in a north-bending arc of the river Seine whose crest includes two islands, the Île Saint-Louis and the larger Île de la Cité, which form the oldest part of the city. The river's mouth on the English Channel (La Manche) is about downstream from the city. The city is spread widely on both banks of the river. Overall, the city is relatively flat, and the lowest point is above sea level. Paris has several prominent hills, the highest of which is Montmartre at . Excluding the outlying parks of Bois de Boulogne and Bois de Vincennes, Paris covers an oval measuring about in area, enclosed by the ring road, the Boulevard Périphérique. The city's last major annexation of outlying territories in 1860 not only gave it its modern form but also created the 20 clockwise-spiralling arrondissements (municipal boroughs). From the 1860 area of , the city limits were expanded marginally to in the 1920s. In 1929, the Bois de Boulogne and Bois de Vincennes forest parks were officially annexed to the city, bringing its area to about . The metropolitan area of the city is . Measured from the 'point zero' in front of its Notre-Dame cathedral, Paris by road is southeast of London, south of Calais, southwest of Brussels, north of Marseille, northeast of Nantes, and southeast of Rouen. Climate Paris has a typical Western European oceanic climate (Köppen: Cfb), which is affected by the North Atlantic Current. The overall climate throughout the year is mild and moderately wet. Summer days are usually warm and pleasant with average temperatures between , and a fair amount of sunshine. Each year, however, there are a few days when the temperature rises above . Longer periods of more intense heat sometimes occur, such as the heat wave of 2003 when temperatures exceeded for weeks, reached on some days and rarely cooled down at night. Spring and autumn have, on average, mild days and fresh nights but are changing and unstable. Surprisingly warm or cool weather occurs frequently in both seasons. In winter, sunshine is scarce; days are cool, and nights are cold but generally above freezing with low temperatures around . Light night frosts are however quite common, but the temperature seldom dips below . Snow falls every year, but rarely stays on the ground. The city sometimes sees light snow or flurries with or without accumulation. Paris has an average annual precipitation of , and experiences light rainfall distributed evenly throughout the year. However, the city is known for intermittent, abrupt, heavy showers. The highest recorded temperature was on 25 July 2019, and the lowest was on 10 December 1879. Administration City government For almost all of its long history, except for a few brief periods, Paris was governed directly by representatives of the king, emperor, or president of France. The city was not granted municipal autonomy by the National Assembly until 1974. For all but 14 months from 1794 to 1977, Paris was the only French commune without a mayor, and thus had less autonomy than the smallest village. For most of the time from 1800 to 1977 (except briefly in 1848 and 1870–71), it was directly controlled by the departmental prefect (the prefect of the Seine until 1968, and the prefect of Paris from 1968 to 1977). The first modern elected mayor of Paris was Jacques Chirac, elected 20 March 1977, becoming the city's first mayor since 1871 and only the fourth since 1794. The current mayor is Anne Hidalgo, a socialist, first elected 5 April 2014 and re-elected 28 June 2020. The mayor of Paris is elected indirectly by Paris voters; the voters of each of the city's 20 arrondissements elect members to the Conseil de Paris (Council of Paris), which subsequently elects the mayor. The council is composed of 163 members, with each arrondissement allocated a number of seats dependent upon its population, from 10 members for each of the least-populated arrondissements (1st through 9th) to 34 members for the most populated (the 15th). The council is elected using closed list proportional representation in a two-round system. Party lists winning an absolute majority in the first round – or at least a plurality in the second round – automatically win half the seats of an arrondissement. The remaining half of seats are distributed proportionally to all lists which win at least 5% of the vote using the highest averages method. This ensures that the winning party or coalition always wins a majority of the seats, even if they don't win an absolute majority of the vote. Once elected, the council plays a largely passive role in the city government, primarily because it meets only once a month. The council is divided between a coalition of the left of 91 members, including the socialists, communists, greens, and extreme left; and 71 members for the centre-right, plus a few members from smaller parties. Each of Paris's 20 arrondissements has its own town hall and a directly elected council (conseil d'arrondissement), which, in turn, elects an arrondissement mayor. The council of each arrondissement is composed of members of the Conseil de Paris and also members who serve only on the council of the arrondissement. The number of deputy mayors in each arrondissement varies depending upon its population. There are a total of 20 arrondissement mayors and 120 deputy mayors. The budget of the city for 2018 is 9.5 billion Euros, with an expected deficit of 5.5 billion Euros. 7.9 billion Euros are designated for city administration, and 1.7 billion Euros for investment. The number of city employees increased from 40,000 in 2001 to 55,000 in 2018. The largest part of the investment budget is earmarked for public housing (262 million Euros) and for real estate (142 million Euros). Métropole du Grand Paris The Métropole du Grand Paris, or simply Grand Paris, formally came into existence on 1 January 2016. It is an administrative structure for co-operation between the City of Paris and its nearest suburbs. It includes the City of Paris, plus the communes of the three departments of the inner suburbs (Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne), plus seven communes in the outer suburbs, including Argenteuil in Val d'Oise and Paray-Vieille-Poste in Essonne, which were added to include the major airports of Paris. The Metropole covers and has a population of 6.945 million persons. The new structure is administered by a Metropolitan Council of 210 members, not directly elected, but chosen by the councils of the member Communes. By 2020 its basic competencies will include urban planning, housing and protection of the environment. The first president of the metropolitan council, Patrick Ollier, a Republican and the mayor of the town of Rueil-Malmaison, was elected on 22 January 2016. Though the Metropole has a population of nearly seven million people and accounts for 25 percent of the GDP of France, it has a very small budget: just 65 million Euros, compared with eight billion Euros for the City of Paris. Regional government The Region of Île de France, including Paris and its surrounding communities, is governed by the Regional Council, which has its headquarters in the 7th arrondissement of Paris. It is composed of 209 members representing the different communes within the region. On 15 December 2015, a list of candidates of the Union of the Right, a coalition of centrist and right-wing parties, led by Valérie Pécresse, narrowly won the regional election, defeating a coalition of Socialists and ecologists. The Socialists had governed the region for seventeen years. The regional council has 121 members from the Union of the Right, 66 from the Union of the Left and 22 from the extreme right National Front. National government As the capital of France, Paris is the seat of France's national government. For the executive, the two chief officers each have their own official residences, which also serve as their offices. The President of the French Republic resides at the Élysée Palace in the 8th arrondissement, while the Prime Minister's seat is at the Hôtel Matignon in the 7th arrondissement. Government ministries are located in various parts of the city; many are located in the 7th arrondissement, near the Hôtel Matignon. Both houses of the French Parliament are located on the Rive Gauche. The upper house, the Senate, meets in the Palais du Luxembourg in the 6th arrondissement, while the more important lower house, the National Assembly, meets in the Palais Bourbon in the 7th arrondissement. The President of the Senate, the second-highest public official in France (the President of the Republic being the sole superior), resides in the Petit Luxembourg, a smaller palace annexe to the Palais du Luxembourg. France's highest courts are located in Paris. The Court of Cassation, the highest court in the judicial order, which reviews criminal and civil cases, is located in the Palais de Justice on the Île de la Cité, while the Conseil d'État, which provides legal advice to the executive and acts as the highest court in the administrative order, judging litigation against public bodies, is located in the Palais-Royal in the 1st arrondissement. The Constitutional Council, an advisory body with ultimate authority on the constitutionality of laws and government decrees, also meets in the Montpensier wing of the Palais Royal. Paris and its region host the headquarters of several international organisations including UNESCO, the Organisation for Economic Co-operation and Development, the International Chamber of Commerce, the Paris Club, the European Space Agency, the International Energy Agency, the Organisation internationale de la Francophonie, the European Union Institute for Security Studies, the International Bureau of Weights and Measures, the International Exhibition Bureau, and the International Federation for Human Rights. Following the motto "Only Paris is worthy of Rome; only Rome is worthy of Paris"; the only sister city of Paris is Rome, although Paris has partnership agreements with many other cities around the world. Police force The security of Paris is mainly the responsibility of the Prefecture of Police of Paris, a subdivision of the Ministry of the Interior. It supervises the units of the National Police who patrol the city and the three neighbouring departments. It is also responsible for providing emergency services, including the Paris Fire Brigade. Its headquarters is on Place Louis Lépine on the Île de la Cité. There are 30,200 officers under the prefecture, and a fleet of more than 6,000 vehicles, including police cars, motorcycles, fire trucks, boats and helicopters. The national police has its own special unit for riot control and crowd control and security of public buildings, called the Compagnies Républicaines de Sécurité (CRS), a unit formed in 1944 right after the liberation of France. Vans of CRS agents are frequently seen in the centre of the city when there are demonstrations and public events. The police are supported by the National Gendarmerie, a branch of the French Armed Forces, though their police operations now are supervised by the Ministry of the Interior. The traditional kepis of the gendarmes were replaced in 2002 with caps, and the force modernised, though they still wear kepis for ceremonial occasions. Crime in Paris is similar to that in most large cities. Violent crime is relatively rare in the city centre. Political violence is uncommon, though very large demonstrations may occur in Paris and other French cities simultaneously. These demonstrations, usually managed by a strong police presence, can turn confrontational and escalate into violence. Cityscape Urbanism and architecture Most French rulers since the Middle Ages made a point of leaving their mark on a city that, contrary to many other of the world's capitals, has never been destroyed by catastrophe or war. In modernising its infrastructure through the centuries, Paris has preserved even its earliest history in its street map. At its origin, before the Middle Ages, the city was composed of several islands and sandbanks in a bend of the Seine; of those, two remain today: Île Saint-Louis and the Île de la Cité. A third one is the 1827 artificially created Île aux Cygnes. Modern Paris owes much of its downtown plan and architectural harmony to Napoleon III and his Prefect of the Seine, Baron Haussmann. Between 1853 and 1870 they rebuilt the city centre, created the wide downtown boulevards and squares where the boulevards intersected, imposed standard facades along the boulevards, and required that the facades be built of the distinctive cream-grey "Paris stone". They also built the major parks around the city centre. The high residential population of its city centre also makes it much different from most other western major cities. Paris's urbanism laws have been under strict control since the early 17th century, particularly where street-front alignment, building height and building distribution is concerned. In recent developments, a 1974–2010 building height limitation of was raised to in central areas and in some of Paris's peripheral quarters, yet for some of the city's more central quarters, even older building-height laws still remain in effect. The Tour Montparnasse was both Paris's and France's tallest building since 1973, but this record has been held by the La Défense quarter Tour First tower in Courbevoie since its 2011 construction. Parisian examples of historical architectural styles date back more than a millennium, including the Romanesque church of the Abbey of Saint-Germain-des-Prés (1014–1163), the early Gothic Architecture of the Basilica of Saint-Denis (1144), the Notre Dame Cathedral (1163–1345), the Flamboyant Gothic of Saint Chapelle (1239–1248), the Baroque churches of Saint-Paul-Saint-Louis (1627–1641) and Les Invalides (1670–1708). The 19th century produced the neoclassical church of La Madeleine (1808–1842), the Palais Garnier serving as an opera house (1875), the neo-Byzantine Basilica of Sacré-Cœur (1875–1919), as well as the exuberant Belle Époque modernism of the Eiffel Tower (1889). Striking examples of 20th-century architecture include the Centre Georges Pompidou by Richard Rogers and Renzo Piano (1977), the Cité des Sciences et de l'Industrie by various architects (1986), the Arab World Institute by Jean Nouvel (1987), the Louvre Pyramid by I. M. Pei (1989) and the Opéra Bastille by Carlos Ott (1989). Contemporary architecture includes the Musée du quai Branly – Jacques Chirac by Jean Nouvel (2006), the contemporary art museum of the Louis Vuitton Foundation by Frank Gehry (2014) and the new Tribunal de grande instance de Paris by Renzo Piano (2018). Housing The most expensive residential streets in Paris in 2018 by average price per square metre were Avenue Montaigne (8th arrondissement), at 22,372 euros per square metre; Place Dauphine (1st arrondissement; 20,373 euros) and the Rue de Furstemberg (6th arrondissement) at 18,839 euros per square metre. The total number of residences in the City of Paris in 2011 was , up from a former high of in 2006. Among these, (85.9 percent) were main residences, (6.8 percent) were secondary residences, and the remaining 7.3 percent were empty (down from 9.2 percent in 2006). Sixty-two percent of its buildings date from 1949 and before, 20 percent were built between 1949 and 1974, and only 18 percent of the buildings remaining were built after that date. Two-thirds of the city's 1.3 million residences are studio and two-room apartments. Paris averages 1.9 people per residence, a number that has remained constant since the 1980s, but it is much less than Île-de-France's 2.33 person-per-residence average. Only 33 percent of principal residence Parisians own their habitation (against 47 percent for the entire Île-de-France): the major part of the city's population is a rent-paying one. Social or public housing represented 19.9 percent of the city's total residences in 2017. Its distribution varies widely throughout the city, from 2.6 percent of the housing in the wealthy 7th arrondissement, to 24 percent in the 20th arrondissement, 26 percent in the 14th arrondissement and 39.9 percent in the 19th arrondissement, on the poorer southwest and northern edges of the city. On the night of 8–9 February 2019, during a period of cold weather, a Paris NGO conducted its annual citywide count of homeless persons. They counted 3,641 homeless persons in Paris, of whom twelve percent were women. More than half had been homeless for more than a year. 2,885 were living in the streets or parks, 298 in train and metro stations, and 756 in other forms of temporary shelter. This was an increase of 588 persons since 2018. Paris and its suburbs Aside from the 20th-century addition of the Bois de Boulogne, the Bois de Vincennes and the Paris heliport, Paris's administrative limits have remained unchanged since 1860. A greater administrative Seine department had been governing Paris and its suburbs since its creation in 1790, but the rising suburban population had made it difficult to maintain as a unique entity. To address this problem, the parent "District de la région parisienne" ('district of the Paris region') was reorganised into several new departments from 1968: Paris became a department in itself, and the administration of its suburbs was divided between the three new departments surrounding it. The district of the Paris region was renamed "Île-de-France" in 1977, but this abbreviated "Paris region" name is still commonly used today to describe the Île-de-France, and as a vague reference to the entire Paris agglomeration. Long-intended measures to unite Paris with its suburbs began on 1 January 2016, when the Métropole du Grand Paris came into existence. Paris's disconnect with its suburbs, its lack of suburban transportation, in particular, became all too apparent with the Paris agglomeration's growth. Paul Delouvrier promised to resolve the Paris-suburbs mésentente when he became head of the Paris region in 1961: two of his most ambitious projects for the Region were the construction of five suburban "villes nouvelles" ("new cities") and the RER commuter train network. Many other suburban residential districts (grands ensembles) were built between the 1960s and 1970s to provide a low-cost solution for a rapidly expanding population: These districts were socially mixed at first, but few residents actually owned their homes (the growing economy made these accessible to the middle classes only from the 1970s). Their poor construction quality and their haphazard insertion into existing urban growth contributed to their desertion by those able to move elsewhere and their repopulation by those with more limited possibilities. These areas, quartiers sensibles ("sensitive quarters"), are in northern and eastern Paris, namely around its Goutte d'Or and Belleville neighbourhoods. To the north of the city, they are grouped mainly in the Seine-Saint-Denis department, and to a lesser extreme to the east in the Val-d'Oise department. Other difficult areas are located in the Seine valley, in Évry et Corbeil-Essonnes (Essonne), in Mureaux, Mantes-la-Jolie (Yvelines), and scattered among social housing districts created by Delouvrier's 1961 "ville nouvelle" political initiative. The Paris agglomeration's urban sociology is basically that of 19th-century Paris: its fortuned classes are situated in its west and southwest, and its middle-to-lower classes are in its north and east. The remaining areas are mostly middle-class citizenry dotted with islands of fortuned populations located there due to reasons of historical importance, namely Saint-Maur-des-Fossés to the east and Enghien-les-Bains to the north of Paris. Demographics The official estimated population of the City of Paris was 2,165,423 on 1 January 2022, according to the INSEE, the official French statistical agency. This was a decline of 11,000 from January 2021, and a drop of 65,000 over six years. Despite the drop, Paris remains the most densely-populated city in Europe, with 252 residents per hectare, not counting parks. This drop was attributed partly to a lower birth rate, the departure of middle-class residents and the possible loss of housing in the city due to short-term rentals for tourism. Paris is the fourth largest municipality in the European Union, following Berlin, Madrid and Rome. Eurostat places Paris (6.5 million people) behind London (8 million) and ahead of Berlin (3.5 million), based on the 2012 populations of what Eurostat calls "urban audit core cities". The population of Paris today is lower than its historical peak of 2.9 million in 1921. The principal reasons were a significant decline in household size, and a dramatic migration of residents to the suburbs between 1962 and 1975. Factors in the migration included de-industrialisation, high rent, the gentrification of many inner quarters, the transformation of living space into offices, and greater affluence among working families. The city's population loss came to a temporary halt at the beginning of the 21st century; the population increased from 2,125,246 in 1999 to 2,240,621 in 2012, before declining again slightly in 2017. It declined again in 2018. Paris is the core of a built-up area that extends well beyond its |

Random Years (7 + 2)" about her relationship with Shepard. Smith was briefly considered for the lead singer position in Blue Öyster Cult. She contributed lyrics to several of the band's songs, including "Debbie Denise" (inspired by her poem "In Remembrance of Debbie Denise"), "Baby Ice Dog", "Career of Evil", "Fire of Unknown Origin", "The Revenge of Vera Gemini" (on which she performs duet vocals), and "Shooting Shark". She was romantically involved at the time with the band's keyboardist, Allen Lanier. During these years, Smith also wrote rock journalism pieces, some of which were published in Rolling Stone and Creem. 1974–1979: Patti Smith Group By 1974, Patti Smith was performing rock music, initially with guitarist, bassist and rock archivist Lenny Kaye, and later with a full band comprising Kaye, Ivan Kral on guitar and bass, Jay Dee Daugherty on drums and Richard Sohl on piano. Kral was a refugee from Czechoslovakia who had moved to the United States in 1966 with his parents, who were diplomats. After the Warsaw Pact invasion of Czechoslovakia in 1968, he decided not to return. Financed by Sam Wagstaff, the band recorded a first single, "Hey Joe / Piss Factory", in 1974. The A-side was a version of the rock standard with the addition of a spoken word piece about fugitive heiress Patty Hearst ("Patty Hearst, you're standing there in front of the Symbionese Liberation Army flag with your legs spread, I was wondering were you gettin' it every night from a black revolutionary man and his women ..."). A court later heard that Hearst had been confined against her will, and had been repeatedly threatened with execution and raped. The B-side describes the helpless alienation Smith had felt while working on a factory assembly line and the salvation she dreams of achieving by escaping to New York. In a 1996 interview which discusses artistic influences during her younger years, Smith said, "I had devoted so much of my girlish daydreams to Rimbaud. Rimbaud was like my boyfriend." Later that same year, she performed spoken poetry on "I Wake Up Screaming" from Ray Manzarek's The Whole Thing Started with Rock & Roll Now It's Out of Control album. The Patti Smith Group was signed by Clive Davis of Arista Records, and in 1975 recorded their first album, Horses, produced by John Cale amid some tension. The album fused punk rock and spoken poetry and begins with a cover of Van Morrison's "Gloria", and Smith's opening words: "Jesus died for somebody's sins but not mine" (an excerpt from "Oath", one of her early poems). The austere cover photograph by Mapplethorpe has become one of rock's classic images. As the popularity of punk rock grew, the Patti Smith Group toured the United States and Europe. The rawer sound of the group's second album, Radio Ethiopia, reflected this. Considerably less accessible than Horses, Radio Ethiopia initially received poor reviews. However, several of its songs have stood the test of time, and Smith still performs them regularly in concert. She has said that Radio Ethiopia was influenced by the band MC5. On January 23, 1977, while touring in support of Radio Ethiopia, Smith accidentally danced off a high stage in Tampa, Florida, and fell 15 feet into a concrete orchestra pit, breaking several neck vertebrae. The injury required a period of rest and an intensive round of physical therapy, during which time she was able to reassess, re-energize and reorganize her life. The Patti Smith Group produced two further albums before the end of the 1970s. Easter (1978) was her most commercially successful record, containing the single "Because the Night" co-written with Bruce Springsteen. Wave (1979) was less successful, although the songs "Frederick" and "Dancing Barefoot" both received commercial airplay. 1980–1995: Marriage Before the release of Wave, Smith, now separated from long-time partner Allen Lanier, met Fred "Sonic" Smith, former guitar player for Detroit rock band MC5 and his own Sonic's Rendezvous Band, who adored poetry as much as she did. Waves "Dancing Barefoot" (inspired by Jeanne Hébuterne and her tragic love for Amedeo Modigliani) and "Frederick" were both dedicated to him. The running joke at the time was that she married Fred only because she would not have to change her name. They had a son, Jackson (b. 1982), who would go on to marry The White Stripes drummer, Meg White, in 2009; and a daughter, Jesse Paris, who is also a musician and composer (b. 1987). Through most of the 1980s Smith was in semi-retirement from music, living with her family north of Detroit in St. Clair Shores, Michigan. In June 1988, she released the album Dream of Life, which included the song "People Have the Power". Fred Smith died on November 4, 1994, of a heart attack. Shortly afterward, Patti faced the unexpected death of her brother Todd. When her son Jackson turned 14, Smith decided to move back to New York. After the impact of these deaths, her friends Michael Stipe of R.E.M. and Allen Ginsberg (whom she had known since her early years in New York) urged her to go back out on the road. She toured briefly with Bob Dylan in December 1995 (chronicled in a book of photographs by Stipe). 1996–2003: Re-emergence In 1996, Smith worked with her long-time colleagues to record Gone Again, featuring "About a Boy", a tribute to Kurt Cobain. That same year she collaborated with Stipe on "E-Bow the Letter", a song on R.E.M.'s New Adventures in Hi-Fi, which she has also performed live with the band. After the release of Gone Again, Patti Smith recorded two new albums: Peace and Noise in 1997 (with the single "1959", about the invasion of Tibet) and Gung Ho in 2000 (with songs about Ho Chi Minh and Smith's late father). Songs "1959" and "Glitter in Their Eyes" were nominated for the Grammy Award for Best Female Rock Vocal Performance. A box set of her work up to that time, The Patti Smith Masters, came out in 1996, and 2002 saw the release of Land (1975–2002), a two-CD compilation that includes a cover of Prince's "When Doves Cry". Smith's solo art exhibition Strange Messenger was hosted at The Andy Warhol Museum in Pittsburgh on September 28, 2002. 2004–2009 On April 27, 2004, Patti Smith released Trampin', which included several songs about motherhood, partly in tribute to Smith's mother, who had died two years before. It was her first album on Columbia Records, soon to become a sister label to her previous home Arista Records. Smith curated the Meltdown festival in London on June 25, 2005, the penultimate event being the first live performance of Horses in its entirety. Guitarist Tom Verlaine took Oliver Ray's place. This live performance was released later in the year as Horses/Horses. On July 10, 2005, Smith was named a Commander of the Ordre des Arts et des Lettres by the French Ministry of Culture. In addition to Smith's influence on rock music, the Minister also noted her appreciation of Arthur Rimbaud. In August 2005, Smith gave a literary lecture about the poems of Arthur Rimbaud and William Blake. On October 15, 2006, Patti Smith performed at the CBGB nightclub, with a 3½-hour tour de force to close out Manhattan's music venue. She took the stage at 9:30 p.m. (EDT) and closed for the night (and forever for the venue) at a few minutes after 1:00 am, performing her song "Elegie", and finally reading a list of punk rock musicians and advocates who had died in the previous years. Smith was inducted into the Rock and Roll Hall of Fame on March 12, 2007. She dedicated her award to the memory of her late husband, Fred, and gave a performance of The Rolling Stones staple "Gimme Shelter". As the closing number of the Rock and Roll Hall of Fame Induction Ceremony, Smith's "People Have the Power" was used for the big celebrity jam that always ends the program. "Gimme Shelter" appeared on her tenth album, Twelve, an all-covers album issued in April 2007 on the Columbia label. From November 2006 to January 2007, an exhibition called 'Sur les Traces' at Trolley Gallery, London, featured polaroid prints taken by Patti Smith and donated to Trolley to raise awareness and funds for the publication of Double Blind: Lebanon Conflict 2006, a book with photographs by Paolo Pellegrin, a member of Magnum Photos. She also participated in the DVD commentary for Aqua Teen Hunger Force Colon Movie Film for Theaters. From March 28 to June 22, 2008, the Fondation Cartier pour l'Art Contemporain in Paris hosted a major exhibition of the visual artwork of Patti Smith, Land 250, drawn from pieces created between 1967 and 2007. At the 2008 Rowan Commencement ceremony, Smith received an honorary doctorate degree for her contributions to popular culture. Smith was the subject of a 2008 documentary film by Steven Sebring titled Patti Smith: Dream of Life. A live album by Patti Smith and Kevin Shields, The Coral Sea was released in July 2008. On September 10, 2009, after a week of smaller events and exhibitions in the city, Smith played an open-air concert in Florence's Piazza Santa Croce, commemorating her performance in the same city 30 years earlier. In the meantime, she contributed with a special introduction to Jessica Lange's book 50 Photographs (2009). 2010–present Smith's book, Just Kids, a memoir of her time in 1970s Manhattan and her relationship with Robert Mapplethorpe, was published in 2010; it later won the National Book Award for Nonfiction. In 2018 a new edition with many added photographs and illustrations was published. She also headlined a benefit concert headed by bandmate Tony Shanahan, for The Court Tavern of New Brunswick. Smith's set included "Gloria", "Because the Night" and "People Have the Power". She has a brief cameo in Jean-Luc Godard's 2010 Film Socialisme, which was first screened in the Un Certain Regard section at the 2010 Cannes Film Festival. In 2012, Smith received an honorary doctorate in fine arts from Pratt Institute, along with architect Daniel Libeskind, MoMA director Glenn Lowry, former NYC Landmarks Commissioner Barbaralee Diamonstein-Spielvogel, novelist Jonathan Lethem, and director Steven Soderbergh. Following the conferral of her degree, Smith delivered the commencement address and sang/played two songs accompanied by long-time band member Lenny Kaye. In her remarks, Smith explained that in 1967 when she moved to New York City (Brooklyn), she would never have been accepted into Pratt, but most of her friends (including Mapplethorpe) were students at Pratt and she spent countless hours on the Pratt campus. She added that it was through her friends and their Pratt professors that she learned much of her own artistic skills, making the honor from the institute particularly poignant for Smith 43 years later. Smith was one of the winners of the 2011 Polar Music Prize. She made her television acting debut at the age of 64 on the TV series Law & Order: Criminal Intent, appearing in an episode called "Icarus". In 2011, Smith was working on a crime novel set in London. "I've been working on a detective story that starts at the St Giles in the Fields church in London for the last two years", she told NME adding that she "loved detective stories" having been a fan of British fictional detective Sherlock Holmes and U.S. crime author Mickey Spillane as a girl. Part of the book will be set in Gothenburg, Sweden. Following the death of her husband in 1994, Smith began devoting time to what she terms "pure photography" (a method of capturing still objects without using a flash). In 2011, Smith announced the first museum exhibition of her photography in the United States, Camera Solo. She named the project after a sign she saw in the abode of Pope Celestine V, which translates as "a room of one's own", and which Smith felt best described her solitary method of photography. The exhibition featured artifacts which were the everyday items or places of significance of artists whom Smith admires, including Rimbaud, Baudelaire, Keats, and Blake. In February 2012, she was a guest at the Sanremo Music Festival. | Smith performed "People Have the Power" at Riverside Church, Manhattan, to celebrate the 20th anniversary of Democracy Now. She was joined by Michael Stipe. On December 10, 2016, Smith attended the Nobel Prize Award Ceremony in Stockholm on behalf of Bob Dylan, winner of the Nobel Prize in Literature, who himself could not be present due to prior commitments. After the official presentation speech for the literary prize by Horace Engdahl, the perpetual secretary of the Swedish Academy, Smith sang the Dylan song "A Hard Rain's a-Gonna Fall". Possibly overcome by nerves she sang "I saw the babe that was just bleedin’", the wrong words to the second verse and became unable to continue. She stopped, and after a brief apology, resumed the song, which earned her a jubilant applause at the end. In 2017, Smith appeared as herself in Song to Song directed by Terrence Malick, opposite Rooney Mara and Ryan Gosling. She later made an appearance at the Detroit show of U2's The Joshua Tree 2017 tour and performed "Mothers of the Disappeared" with the band. In 2018, Smith's concert-documentary film Horses: Patti Smith and her Band premiered at the 2018 Tribeca Film Festival to wide acclaim. In addition, Smith narrated in Darren Aronofsky's VR experience Spheres: Songs of Spacetime alongside Millie Bobby Brown and Jessica Chastain. In 2019, Smith performed her anthem "People Have the Power" with Stewart Copeland and Choir! Choir! Choir! at Onassis Festival 2019: Democracy Is Coming, co-presented by The Public Theatre and Onassis USA. Later that year she released her latest book, Year of the Monkey. "A captivating, redemptive chronicle of a year in which Smith looked intently into the abyss", stated Kirkus Reviews. Smith was set to receive the International Humanities Prize from Washington University in St. Louis in November 2020; however, the ceremony was canceled due to the COVID-19 pandemic. Legacy Smith has been an inspiration for Michael Stipe of R.E.M. Listening to her album Horses made a huge impact on him; he said later, "I decided then that I was going to start a band." In 1998, Stipe published a collection of photos called Two Times Intro: On the Road with Patti Smith. Stipe sings backing vocals on Smith's songs "Last Call" and "Glitter in Their Eyes". Smith sang background vocals on R.E.M.'s songs "E-Bow the Letter" and "Blue". The Australian alternative rock band, The Go-Betweens dedicated a track ("When She Sang About Angels") off their 2000 album, The Friends of Rachel Worth, to Smith's long-time influence. In 2004, Shirley Manson of Garbage spoke of Smith's influence on her in Rolling Stones issue "The Immortals: 100 Greatest Artists of All Time", in which Patti Smith was counted number 47. The Smiths members Morrissey and Johnny Marr share an appreciation for Smith's Horses, and revealed that their song "The Hand That Rocks the Cradle" is a reworking of one of the album's tracks, "Kimberly". In 2004, Sonic Youth released an album called Hidros 3 (to Patti Smith). U2 also cites Patti Smith as an influence. In 2005 Scottish singer-songwriter KT Tunstall released the single "Suddenly I See" as a tribute of sorts to Patti Smith. Canadian actor Elliot Page frequently mentions Smith as one of his idols and has done various photo shoots replicating famous Smith photos, as well as Irish actress Maria Doyle Kennedy who often refers to Smith as a major influence. In 1978 and 1979, Gilda Radner portrayed a character called Candy Slice on Saturday Night Live based on Smith. Alternative rock singer-songwriter Courtney Love of Hole heavily credited Smith as being a huge influence on her; Love received Smith's album Horses in juvenile hall as a teenager, and "realized that you could do something that was completely subversive that didn't involve violence [or] felonies. I stopped making trouble," said Love. "I stopped." Hole's classic track "Violet" features the lyrics "And the sky was all violet / I want it again, but violent, more violent", alluding to lyrics from Smith's "Kimberly". Love later stated that she considered "Rock n Roll Nigger" the greatest rock song of all time. American pop singer Madonna has also named Smith as one of her biggest influences. Anglo-Celtic rock band The Waterboys' debut single, "A Girl Called Johnny", was written as a tribute to Smith. In 2018, the English band Florence and the Machine dedicated the High as Hope album song "Patricia" to Smith. The lyrics reference Patricia as Florence Welch's "North Star". Canadian country musician Orville Peck cited Smith as having had a big impact on him, stating that Smith's album Horses introduced him to a new and different way to make music. Activism In 1993, Smith contributed "Memorial Tribute (Live)" to the AIDS-Benefit Album No Alternative produced by the Red Hot Organization. Smith was a supporter of the Green Party and backed Ralph Nader in the 2000 United States presidential election. She led the crowd singing "Over the Rainbow" and "People Have the Power" at the campaign's rallies, and also performed at several of Nader's subsequent "Democracy Rising" events. Smith was a speaker and singer at the first protests against the Iraq War as U.S. President George W. Bush spoke to the United Nations General Assembly. Smith supported Democratic candidate John Kerry in the 2004 election. Bruce Springsteen continued performing her "People Have the Power" at Vote for Change campaign events. In the winter of 2004–2005, Smith toured again with Nader in a series of rallies against the Iraq War and called for the impeachment of Bush. Smith premiered two new protest songs in London in September 2006. Louise Jury, writing in The Independent, characterized them as "an emotional indictment of American and Israeli foreign policy". The song "Qana" was about the Israeli airstrike on the Lebanese village of Qana. "Without Chains" is about Murat Kurnaz, a Turkish citizen who was born and raised in Germany, held at Guantanamo Bay detainment camp for four years. Jury's article quotes Smith as saying: In an interview, Smith stated that Kurnaz's family has contacted her and that she wrote a short preface for the book that he was writing. Kurnaz's book, Five Years of My Life, was published in English by Palgrave Macmillan in March 2008, with Patti's introduction. On March 26, 2003, ten days after Rachel Corrie's death, Smith appeared in Austin, Texas, and performed an anti-war concert. She subsequently wrote a song "Peaceable Kingdom" which was inspired by and is dedicated to Rachel Corrie. In 2009, in her Meltdown concert in Festival Hall, she paid homage to the Iranians taking part in post-election protests by saying "Where is My Vote?" in a version of the song "People Have the Power". In 2015, Smith appeared with Nader, spoke and performed the songs "Wing" and "People Have the Power" during the American Museum of Tort Law convocation ceremony in Winsted, Connecticut. Smith spoke, read poetry, and performed several songs accompanied by her daughter Jesse at Nader's Breaking Through Power conference at DAR Constitution Hall in Washington, D.C. A long-time supporter of Tibet House US, she performs yearly at their benefit at Carnegie Hall. In 2020, Smith contributed signed first-edition copies of her books to the Passages bookshop in Portland, Oregon, after the store was burgled of a number of valuable first-edition and other books by various authors. She did so after reading about the burglary and its impact on the owner, stating that she "loves bookstores." She regards climate change as the overriding issue of our time, performing at the opening of COP26 in 2021. Beliefs Religion Smith was raised a Jehovah's Witness and had a strong religious upbringing and a Biblical education. She left organized religion as a teenager because she felt it was too confining. In response to this experience, she wrote the line "Jesus died for somebody's sins, but not mine" in her cover version of "Gloria" by Them. She has described having an avid interest in Tibetan Buddhism around the age of eleven or twelve, saying |
time. In 2009, it was selected by the Library of Congress for preservation into the National Recording Registry as a "culturally, historically, or aesthetically significant" work. Background Through frequent live performances over the previous year, by 1975 Patti Smith and her band had established themselves as a popular act within the New York City underground rock music scene. Further increasing their popularity was their highly attended two-month residency at the New York City club CBGB with the band Television early that year. The hype surrounding the residency brought Smith to the attention of music industry executive Clive Davis, who was scouting for talent to sign to his recently launched label Arista Records. After being impressed by one of her live performances at CBGB, Davis offered Smith a seven-album recording deal with Arista, and she signed to the label in April 1975. Smith's vision for her debut album was, in her words, "to make a record that would make a certain type of person not feel alone. People who were like me, different ... I wasn't targeting the whole world. I wasn't trying to make a hit record." The title Horses reflected Smith's desire for a rejuvenation of rock music, which she found had grown "calm" in reaction to the social turmoil of the 1960s and the deaths of numerous prominent rock musicians. She elaborated: "Psychologically, somewhere in our hearts, we were all screwed up because those people died ... We all had to pull ourselves together. To me, that's why our record's called Horses. We had to pull the reins on ourselves to recharge ourselves ... We've gotten ourselves back together. It's time to let the horses loose again. We're ready to start moving again." Recording Arista arranged for Smith to begin recording Horses in August 1975. Smith initially suggested that the album should be produced by Tom Dowd. Plans were made to book studio time with Dowd at Criteria in Miami, but these were complicated by his relationship with rival label Atlantic Records. Nonetheless, Smith had a change of heart and instead set out to enlist Welsh musician John Cale, formerly of the Velvet Underground, to produce Horses, as she was impressed by the raw sound of his solo albums, such as 1974's Fear. Cale, who had previously seen Smith perform live and was acquainted with her bassist Ivan Král, accepted. Horses was recorded at Electric Lady Studios in New York City, with Smith retaining the same backing band with whom she performed live—Jay Dee Daugherty on drums, Lenny Kaye on guitar, Ivan Král on bass guitar, and Richard Sohl on keyboards. Cale recalled that the band initially "sounded awful" and played out of tune due to their use of damaged instruments, forcing him to procure the band new instruments before work on the album began. The differences between the work ethics of Cale, who was an experienced recording artist, and of Smith, who at this point was primarily a live performer, became apparent early on in recording, and were a source of tension between the two artists, who frequently argued in the studio. The sole guest musicians on Horses were Allen Lanier of Blue Öyster Cult and Tom Verlaine of Television. Cale had wished to augment the band's playing on certain songs with strings, but Smith vehemently opposed this idea. Lanier, who was Smith's boyfriend at the time, did not get along with Cale and particularly Verlaine. This tension culminated with Lanier and Verlaine getting into a physical altercation during the final recording session, held on September 18. By the end of recording, and for some years immediately following the album's release, Smith was quick to downplay Cale's contributions and suggested that she and her band had ignored his suggestions entirely. In a 1976 interview with Rolling Stone, Smith described the experience: Cale said in 1996 that Smith initially struck him as "someone with an incredibly volatile mouth who could handle any situation", and that as producer on Horses he wanted to capture the energy of her live performances, noting that there "was a lot of power in Patti's use of language, in the way images collided with one another." He described their working relationship during recording as "confrontational and a lot like an immutable force meeting an immovable object." Smith would later attribute much of the tension between herself and Cale to her inexperience with formal studio recording, recalling that she was "very, very suspicious, very guarded and hard to work with" and "made it difficult for him to do some of the things he had to do." She expressed gratitude for Cale's persistence in working with her and her band and found that his production on Horses made the most out of their "adolescent and honest flaws". Musical style Smith characterized Horses as "three-chord rock merged with the power of the word". Describing the music on the album, Consequence of Sounds Lior Phillips noted a minimalist quality that "matched the tone of" the nascent punk rock genre. Author Joe Tarr identified a punk sensibility in the music's reliance on simple chord progressions, while William Ruhlmann of AllMusic cited Lenny Kaye's rudimentary guitar playing, the "anarchic spirit" of Smith's vocals, and the emotionally charged nature of Smith's lyrics as being representative of punk. Tarr wrote that the band "proudly flaunted a garage rock aesthetic", and that Smith "sang with the delirious release of an inspired amateur", emphasizing "honest passion" over technical proficiency. Smith's vocals on the album alternate between being sung and spoken, an approach that, according to Peter Murphy of Hot Press, "challenged the very notion of a demarcation" between the two forms. AllMusic critic Steve Huey observed that Horses borrowed ideas from the avant-garde, with the music showcasing the band's free jazz-inspired interplay and improvisation, while still remaining "firmly rooted in primal three-chord rock & roll." He called Horses "essentially the first art punk album." Smith and her band's propensity for improvisation differentiated them from most of their punk contemporaries, whose songs rarely diverged from straightforward three-chord structures. Throughout Horses, they also tempered their punk sound with elements of other musical styles, balancing more conventional rock songs with excursions into reggae ("Redondo Beach") and jazz ("Birdland"). Lyrics Fiona Sturges of The Guardian described Smith's lyrics on Horses as being steeped in "intricate phrasing and imagery" that "deliberately blurred the lines between punk and poetry." CMJ writer Steve Klinge found that the album's lyrics recalled the energy of Beat poetry and the "revolutionary spirit" of French poet Arthur Rimbaud, one of Smith's primary influences. Smith drew on different sources of lyrical inspiration on Horses, with some songs being autobiographical and others being rooted in dreams and fantastical scenarios. She left the genders of the songs' protagonists ambiguous, a stylistic choice she said was "learnt from Joan Baez, who often sang songs that had a male point of view", while also serving as a declaration "that as an artist, I can take any position, any voice, that I want." Smith's experiences with her family inspired certain songs on Horses. "Redondo Beach", whose lyrics concern a woman who commits suicide following a quarrel with the song's narrator, was written by Smith after an incident involving her and her sister Linda. The two had gotten into a heated argument, prompting Linda to leave their shared apartment and not return until the next day. "Kimberly" is a dedication to its namesake, Smith's younger sister, and finds the singer recounting a childhood memory of holding Kimberly in her arms during a lightning storm. In "Free Money", Smith describes growing up in poverty in New Jersey and recalls her mother fantasizing about winning the lottery. Smith penned other songs about notable public figures. "Birdland" was inspired by A Book of Dreams, a 1973 memoir of Austrian psychoanalyst Wilhelm Reich by his son Peter, and revolves around a narrative in which Peter, at his father's funeral, imagines leaving on a UFO piloted by his father's spirit. "Break It Up" was written about Jim Morrison, lead singer of the Doors. Its lyrics are based on Smith's recollection of her visit to Morrison's grave in Père Lachaise Cemetery, as well as a dream in which she witnessed a winged Morrison stuck to a marble slab, trying and eventually succeeding in breaking free from the stone. "Elegie" is a requiem for rock musician Jimi Hendrix, incorporating a line from his song "1983... (A Merman I Should Turn to Be)". It was recorded, per Smith's request, on the fifth anniversary of Hendrix's death, which fell on September 18, the final day of recording. Smith said that the song was also intended to pay tribute to other deceased rock musicians such as Jim Morrison, Brian Jones, and Janis Joplin. Two songs on Horses are adapted from rock standards: "Gloria", a radical re-imagining of the Them song incorporating verses from Smith's own poem "Oath", and "Land", already a live favorite, which features the first verse of Chris Kenner's "Land of a Thousand Dances". In "Land", Smith weaves the imagery of the Kenner song into an elaborate narrative about a character named Johnny—an allusion to the similarly named homoerotic protagonist of William S. Burroughs' 1971 novel The Wild Boys—while additionally referencing Arthur Rimbaud and, less directly, Jimi Hendrix, whom Smith imagined to be the song's protagonist, "dreaming a simple rock-and-roll song, and it takes him into all these other realms." The characterization of Johnny in "Land" was also inspired by Smith's close friend Robert Mapplethorpe, who had immersed himself in the New York S&M scene; in her memoir Just Kids (2012), Smith refers to Mapplethorpe and Burroughs, sitting together in CBGB, as "Johnny and the horse". Artwork The cover photograph for Horses was taken by Robert Mapplethorpe at the Greenwich Village penthouse apartment of his partner Sam Wagstaff.

Embedded on the jacket is a horse pin that | handle any situation", and that as producer on Horses he wanted to capture the energy of her live performances, noting that there "was a lot of power in Patti's use of language, in the way images collided with one another." He described their working relationship during recording as "confrontational and a lot like an immutable force meeting an immovable object." Smith would later attribute much of the tension between herself and Cale to her inexperience with formal studio recording, recalling that she was "very, very suspicious, very guarded and hard to work with" and "made it difficult for him to do some of the things he had to do." She expressed gratitude for Cale's persistence in working with her and her band and found that his production on Horses made the most out of their "adolescent and honest flaws". Musical style Smith characterized Horses as "three-chord rock merged with the power of the word". Describing the music on the album, Consequence of Sounds Lior Phillips noted a minimalist quality that "matched the tone of" the nascent punk rock genre. Author Joe Tarr identified a punk sensibility in the music's reliance on simple chord progressions, while William Ruhlmann of AllMusic cited Lenny Kaye's rudimentary guitar playing, the "anarchic spirit" of Smith's vocals, and the emotionally charged nature of Smith's lyrics as being representative of punk. Tarr wrote that the band "proudly flaunted a garage rock aesthetic", and that Smith "sang with the delirious release of an inspired amateur", emphasizing "honest passion" over technical proficiency. Smith's vocals on the album alternate between being sung and spoken, an approach that, according to Peter Murphy of Hot Press, "challenged the very notion of a demarcation" between the two forms. AllMusic critic Steve Huey observed that Horses borrowed ideas from the avant-garde, with the music showcasing the band's free jazz-inspired interplay and improvisation, while still remaining "firmly rooted in primal three-chord rock & roll." He called Horses "essentially the first art punk album." Smith and her band's propensity for improvisation differentiated them from most of their punk contemporaries, whose songs rarely diverged from straightforward three-chord structures. Throughout Horses, they also tempered their punk sound with elements of other musical styles, balancing more conventional rock songs with excursions into reggae ("Redondo Beach") and jazz ("Birdland"). Lyrics Fiona Sturges of The Guardian described Smith's lyrics on Horses as being steeped in "intricate phrasing and imagery" that "deliberately blurred the lines between punk and poetry." CMJ writer Steve Klinge found that the album's lyrics recalled the energy of Beat poetry and the "revolutionary spirit" of French poet Arthur Rimbaud, one of Smith's primary influences. Smith drew on different sources of lyrical inspiration on Horses, with some songs being autobiographical and others being rooted in dreams and fantastical scenarios. She left the genders of the songs' protagonists ambiguous, a stylistic choice she said was "learnt from Joan Baez, who often sang songs that had a male point of view", while also serving as a declaration "that as an artist, I can take any position, any voice, that I want." Smith's experiences with her family inspired certain songs on Horses. "Redondo Beach", whose lyrics concern a woman who commits suicide following a quarrel with the song's narrator, was written by Smith after an incident involving her and her sister Linda. The two had gotten into a heated argument, prompting Linda to leave their shared apartment and not return until the next day. "Kimberly" is a dedication to its namesake, Smith's younger sister, and finds the singer recounting a childhood memory of holding Kimberly in her arms during a lightning storm. In "Free Money", Smith describes growing up in poverty in New Jersey and recalls her mother fantasizing about winning the lottery. Smith penned other songs about notable public figures. "Birdland" was inspired by A Book of Dreams, a 1973 memoir of Austrian psychoanalyst Wilhelm Reich by his son Peter, and revolves around a narrative in which Peter, at his father's funeral, imagines leaving on a UFO piloted by his father's spirit. "Break It Up" was written about Jim Morrison, lead singer of the Doors. Its lyrics are based on Smith's recollection of her visit to Morrison's grave in Père Lachaise Cemetery, as well as a dream in which she witnessed a winged Morrison stuck to a marble slab, trying and eventually succeeding in breaking free from the stone. "Elegie" is a requiem for rock musician Jimi Hendrix, incorporating a line from his song "1983... (A Merman I Should Turn to Be)". It was recorded, per Smith's request, on the fifth anniversary of Hendrix's death, which fell on September 18, the final day of recording. Smith said that the song was also intended to pay tribute to other deceased rock musicians such as Jim Morrison, Brian Jones, and Janis Joplin. Two songs on Horses are adapted from rock standards: "Gloria", a radical re-imagining of the Them song incorporating verses from Smith's own poem "Oath", and "Land", already a live favorite, which features the first verse of Chris Kenner's "Land of a Thousand Dances".

Smith, shrouded in natural light, is seen wearing a plain white shirt, which she had purchased at a Salvation Army shop on the Bowery, and slinging a black jacket over her shoulder and her favorite black ribbon around her collar. Embedded on the jacket is a horse pin that Allen Lanier had given her. Smith described her appearance as recalling those of French poet Charles Baudelaire and, in the slinging of the jacket, American singer and actor Frank Sinatra. She recalled that Mapplethorpe "took, like, twelve pictures, and at about the eighth one, he said, 'I have it.' I said, 'How do you know?' and he said, 'I just know,' and I said, 'Okay.' And that was it." The black-and-white treatment and androgynous pose were a departure from the typical promotional images of female singers of the time. Arista executives wanted to make various changes to the photograph, but Smith overruled their suggestions. Clive Davis later wrote that he was initially conflicted about the image, recognizing its "power" but feeling that it would confuse audiences unfamiliar with Smith and her style of music. He put aside his reservations and approved the cover after coming to a realization that he needed "to trust her artistic instincts thoroughly". Feminist writer Camille Paglia later referred to the Horses cover photograph as "one of the greatest pictures ever taken of a woman." In 2017, World Cafe presenter Talia Schlanger wrote that "Smith's unapologetic androgyny predates a time when that was an en vogue or even available option for women, and represents a seminal moment in the reversal of the female gaze. Smith is looking at you, and could care less what you think about looking at her. That was radical for a woman in 1975. It is still radical today." Smith herself stated that she had not intended to make a "big statement" with the cover, which she said simply reflected the way she dressed. "I wasn't thinking that I was going to break any boundaries. I just like dressing like Baudelaire," she remarked in 1996.Scottish singer/songwriter K T Tunstall cited the cover as the inspiration behind her first hit single “Suddenly I See” Release and reception On September 18, 1975, the same day that they finished recording Horses, Smith and her band performed a live show in support of the upcoming album at an Arista convention, where they were personally introduced by Clive Davis. They previewed five songs from the album: "Birdland", "Redondo Beach", "Break It Up", "Land", and, as their encore, "Free Money". In a contemporary account, journalist Lisa Robinson |
a fishing village that bore the name "Panamá", which purportedly meant "an abundance of fish", when the Spanish colonizers first landed in the area. The exact location of the village is unknown. The legend is usually corroborated by Captain Antonio Tello de Guzmán's diary entries, who reports landing at an unnamed village while exploring the Pacific coast of Panama in 1515; he only describes the village as a "same small indigenous fishing town". In 1517, Don Gaspar de Espinosa, a Spanish lieutenant, decided to settle a post in the same location Guzmán described. In 1519, Pedrarias Dávila decided to establish the Spanish Empire's Pacific port at the site. The new settlement replaced Santa María la Antigua del Darién, which had lost its function within the Crown's global plan after the Spanish exploitation of the riches in the Pacific began. The official definition and origin of the name as promoted by Panama's Ministry of Education is the "abundance of fish, trees and butterflies". This is the usual description given in social studies textbooks. History At the time of the arrival of the Spanish in the 16th century, the known inhabitants of Panama included the Cuevas and the Coclé tribes. These people have nearly disappeared, as they had no immunity from European infectious diseases. Pre-Columbian period The Isthmus of Panama was formed about three million years ago when the land bridge between North and South America finally became complete, and plants and animals gradually crossed it in both directions. The existence of the isthmus affected the dispersal of people, agriculture and technology throughout the American continent from the appearance of the first hunters and collectors to the era of villages and cities. The earliest discovered artifacts of indigenous peoples in Panama include Paleo-Indian projectile points. Later central Panama was home to some of the first pottery-making in the Americas, for example the cultures at Monagrillo, which date back to 2500–1700 BC. These evolved into significant populations best known through their spectacular burials (dating to c. 500–900 AD) at the Monagrillo archaeological site, and their beautiful Gran Coclé style polychrome pottery. The monumental monolithic sculptures at the Barriles (Chiriqui) site are also important traces of these ancient isthmian cultures. Before Europeans arrived Panama was widely settled by Chibchan, Chocoan, and Cueva peoples. The largest group were the Cueva (whose specific language affiliation is poorly documented). The size of the indigenous population of the isthmus at the time of European colonization is uncertain. Estimates range as high as two million people, but more recent studies place that number closer to 200,000. Archaeological finds and testimonials by early European explorers describe diverse native isthmian groups exhibiting cultural variety and suggesting people developed by regular regional routes of commerce. When Panama was colonized, the indigenous peoples fled into the forest and nearby islands. Scholars believe that infectious disease was the primary cause of the population decline of American natives. The indigenous peoples had no acquired immunity to diseases such as smallpox which had been chronic in Eurasian populations for centuries. Conquest to 1799 Rodrigo de Bastidas sailed westward from Venezuela in 1501 in search of gold, and became the first European to explore the isthmus of Panama. A year later, Christopher Columbus visited the isthmus, and established a short-lived settlement in the Darien. Vasco Núñez de Balboa's tortuous trek from the Atlantic to the Pacific in 1513 demonstrated that the isthmus was indeed the path between the seas, and Panama quickly became the crossroads and marketplace of Spain's empire in the New World. King Ferdinand II assigned Pedro Arias Dávila as Royal Governor. He arrived in June 1514 with a 19 vessels and 1,500 men. In 1519, Dávila founded Panama City. Gold and silver were brought by ship from South America, hauled across the isthmus, and loaded aboard ships for Spain. The route became known as the Camino Real, or Royal Road, although it was more commonly known as Camino de Cruces (Road of Crosses) because of the number of gravesites along the way. Panama was under Spanish rule for almost 300 years (1538–1821), and became part of the Viceroyalty of Peru, along with all other Spanish possessions in South America. From the outset, Panamanian identity was based on a sense of "geographic destiny", and Panamanian fortunes fluctuated with the geopolitical importance of the isthmus. The colonial experience spawned Panamanian nationalism and a racially complex and highly stratified society, the source of internal conflicts that ran counter to the unifying force of nationalism. In 1538 the Real Audiencia of Panama was established, initially with jurisdiction from Nicaragua to Cape Horn, until the conquest of Peru. A Real Audiencia was a judicial district that functioned as an appeals court. Each audiencia had an oidor (Spanish: hearer, a judge). Spanish authorities had little control over much of the territory of Panama. Large sections managed to resist conquest and missionization until very late in the colonial era. Because of this, indigenous people of the area were often referred to as "indios de guerra" (war Indians) who resisted Spanish attempts to conquer them or missionize them. However, Panama was enormously important to Spain strategically because it was the easiest way to transship silver mined in Peru to Europe. Silver cargoes were landed at Panama and then taken overland to Portobello or Nombre de Dios on the Caribbean side of the isthmus for further shipment. Asides from the European route, there was also an Asian-American route, which led to traders and adventurers carrying silver from Peru going through Panama to reach Acapulco, Mexico before sailing to Manila, Philippines using the famed Manila Galleons. Because of incomplete Spanish control, the Panama route was vulnerable to attack from pirates (mostly Dutch and English), and from "new world" Africans called cimarrons who had freed themselves from enslavement and lived in communes or palenques around the Camino Real in Panama's Interior, and on some of the islands off Panama's Pacific coast. One such famous community amounted to a small kingdom under Bayano, which emerged in the 1552 to 1558. Sir Francis Drake's famous raids on Panama in 1572–73 and John Oxenham's crossing to the Pacific Ocean were aided by Panama cimarrons, and Spanish authorities were only able to bring them under control by making an alliance with them that guaranteed their freedom in exchange for military support in 1582. The prosperity enjoyed during the first two centuries (1540–1740) while contributing to colonial growth; the placing of extensive regional judicial authority (Real Audiencia) as part of its jurisdiction; and the pivotal role it played at the height of the Spanish Empire – the first modern global empire – helped define a distinctive sense of autonomy and of regional or national identity within Panama well before the rest of the colonies. The end of the encomienda system in Azuero, however, sparked the conquest of Veraguas in that same year. Under the leadership of Francisco Vázquez, the region of Veraguas passed into Castilian rule in 1558. In the newly conquered region, the old system of encomienda was imposed. On the other hand, the Panamanian movement for independence can be indirectly attributed to the abolition of the encomienda system in the Azuero Peninsula, set forth by the Spanish Crown, in 1558 because of repeated protests by locals against the mistreatment of the native population. In its stead, a system of medium and smaller-sized landownership was promoted, thus taking away the power from the large landowners and into the hands of medium and small-sized proprietors. Panama was the site of the ill-fated Darien scheme, which set up a Scottish colony in the region in 1698. This failed for a number of reasons, and the ensuing debt contributed to the union of England and Scotland in 1707. In 1671, the privateer Henry Morgan, licensed by the English government, sacked and burned the city of Panama – the second most important city in the Spanish New World at the time. In 1717 the viceroyalty of New Granada (northern South America) was created in response to other Europeans trying to take Spanish territory in the Caribbean region. The Isthmus of Panama was placed under its jurisdiction. However, the remoteness of New Granada's capital, Santa Fe de Bogotá (the modern capital of Colombia) proved a greater obstacle than the Spanish crown anticipated as the authority of New Granada was contested by the seniority, closer proximity, and previous ties to the viceroyalty of Lima and even by Panama's own initiative. This uneasy relationship between Panama and Bogotá would persist for centuries. In 1744, Bishop Francisco Javier de Luna Victoria DeCastro established the College of San Ignacio de Loyola and on June 3, 1749, founded La Real y Pontificia Universidad de San Javier. By this time, however, Panama's importance and influence had become insignificant as Spain's power dwindled in Europe and advances in navigation technique increasingly permitted ships to round Cape Horn in order to reach the Pacific. While the Panama route was short it was also labor-intensive and expensive because of the loading and unloading and laden-down trek required to get from the one coast to the other. 1800s As the Spanish American wars of independence were heating up all across Latin America, Panama City was preparing for independence; however, their plans were accelerated by the unilateral Grito de La Villa de Los Santos (Cry From the Town of Saints), issued on November 10, 1821, by the residents of Azuero without backing from Panama City to declare their separation from the Spanish Empire. In both Veraguas and the capital this act was met with disdain, although on differing levels. To Veraguas, it was the ultimate act of treason, while to the capital, it was seen as inefficient and irregular, and furthermore forced them to accelerate their plans. Nevertheless, the Grito was a sign, on the part of the residents of Azuero, of their antagonism toward the independence movement in the capital. Those in the capital region in turn regarded the Azueran movement with contempt, since the separatists in Panama City believed that their counterparts in Azuero were fighting not only for independence from Spain, but also for their right to self-rule apart from Panama City once the Spaniards were gone. It was seen as a risky move on the part of Azuero, which lived in fear of Colonel José Pedro Antonio de Fábrega y de las Cuevas (1774–1841). The colonel was a staunch loyalist and had all of the isthmus' military supplies in his hands. They feared quick retaliation and swift retribution against the separatists. What they had counted on, however, was the influence of the separatists in the capital. Ever since October 1821, when the former Governor General, Juan de la Cruz Murgeón, left the isthmus on a campaign in Quito and left a colonel in charge, the separatists had been slowly converting Fábrega to the separatist side. So, by November 10, Fábrega was now a supporter of the independence movement. Soon after the separatist declaration of Los Santos, Fábrega convened every organization in the capital with separatist interests and formally declared the city's support for independence. No military repercussions occurred because of skillful bribing of royalist troops. Post-colonial Panama In the 80 years following independence from Spain, Panama was a subdivision of Gran Colombia, after voluntarily joining the country at the end of 1821. The people of the isthmus made over 80 attempts to secede from Colombia. They came close to success in 1831, then again during the Thousand Days' War of 1899–1902, understood among indigenous Panamanians as a struggle for land rights under the leadership of Victoriano Lorenzo. The US intent to influence the area, especially the Panama Canal's construction and control, led to the separation of Panama from Colombia in 1903 and its establishment as a nation. When the Senate of Colombia rejected the Hay–Herrán Treaty on January 22, 1903, the United States decided to support and encourage the Panamanian separatist movement In November 1903 Panama, tacitly supported by the United States, proclaimed its independence and concluded the Hay–Bunau-Varilla Treaty with the United States without the presence of a single Panamanian. Philippe Bunau-Varilla, a French engineer and lobbyist represented Panama even though Panama's president and a delegation had arrived in New York to negotiate the treaty. The treaty was quickly drafted and signed the night before the Panamanian delegation arrived in Washington. Mr. Bunau-Varilla was in the employ of the French Canal company that had failed and was now bankrupt. The treaty granted rights to the United States "as if it were sovereign" in a zone roughly wide and long. In that zone, the US would build a canal, then administer, fortify, and defend it "in perpetuity". In 1914 the United States completed the existing canal. Because of the strategic importance of the canal during World War II, the US extensively fortified access to it. From 1903 to 1968, Panama was a constitutional democracy dominated by a commercially oriented oligarchy. During the 1950s, the Panamanian military began to challenge the oligarchy's political hegemony. The early 1960s saw also the beginning of sustained pressure in Panama for the renegotiation of the Hay–Bunau-Varilla Treaty, including riots that broke out in early 1964, resulting in widespread looting and dozens of deaths, and the evacuation of the American embassy. Amid negotiations for the Robles–Johnson treaty, Panama held elections in 1968. The candidates were: Dr. Arnulfo Arias Madrid, Unión Nacional (National Union) Antonio González Revilla, Democracia Cristiana (Christian Democrats) Engr. David Samudio, Alianza del Pueblo (People's Alliance) who had the government's support. Arias Madrid was declared the winner of elections that were marked by violence and accusations of fraud against Alianza del Pueblo. On October 1, 1968, Arias Madrid took office as president of Panama, promising to lead a government of "national union" that would end the reigning corruption and pave the way for a new Panama. A week and a half later, on October 11, 1968, the National Guard (Guardia Nacional) ousted Arias and initiated the downward spiral that would culminate with the United States' invasion in 1989. Arias, who had promised to respect the hierarchy of the National Guard, broke the pact and started a large restructuring of the Guard. To preserve the Guard's and his vested interests, Lieutenant Colonel Omar Torrijos Herrera and Major Boris Martínez commanded another military coup against a civilian government in Panamanian republican history. (The action was reminiscent of the 1940s when strong man Colonel Jose Remon removed three duly elected presidents. Remon finally ran for president himself in 1952. He controlled the National Guard which abused the opposition during the campaign and even stole election boxes on election day.) The military justified itself by declaring that Arias Madrid was trying to install a dictatorship, and promised a return to constitutional rule. In the meantime, the Guard began a series of populist measures that would gain support for the coup. Among them were: Price freezing on food, medicine and other goods until January 31, 1969 rent level freeze legalization of the permanence of squatting families in boroughs surrounding the historic site of Panama Viejo Parallel to this, the military began a policy of repression against the opposition, who were labeled communists. The military appointed a Provisional Government Junta that was to arrange new elections. However, the National Guard would prove to be very reluctant to abandon power and soon began calling itself El Gobierno Revolucionario (The Revolutionary Government). Post-1970 Under Omar Torrijos's control, the military transformed the political and economic structure of the country, initiating massive coverage of social security services and expanding public education. The constitution was changed in 1972. To reform the constitution, the military created a new organization, the Assembly of Corregimiento Representatives, which replaced the National Assembly. The new assembly, also known as the Poder Popular (Power of the People), was composed of 505 members selected by the military with no participation from political parties, which the military had eliminated. The new constitution proclaimed Omar Torrijos as the Maximum Leader of the Panamanian Revolution, and conceded him unlimited power for six years, although, to keep a façade of constitutionality, Demetrio B. Lakas was appointed president for the same period. In 1981, Torrijos died in a plane crash. Torrijos' death altered the tone of Panama's political evolution. Despite the 1983 constitutional amendments which proscribed a political role for the military, the Panama Defense Force (PDF), as they were then known, continued to dominate Panamanian political life. By this time, General Manuel Antonio Noriega was firmly in control of both the PDF and the civilian government. In the 1984 elections, the candidates were Nicolás Ardito Barletta Vallarino, supported by the military in a union called UNADE Arnulfo Arias Madrid, for the opposition union ADO ex-General Rubén Darío Paredes, who had been forced to an early retirement by Noriega, running for Partido Nacionalista Popular PNP ("Popular Nationalist Party") Carlos Iván Zúñiga, running for Partido Acción Popular (PAPO) meaning "Popular Action Party" Barletta was declared the winner of elections that had been clearly won by Arias. Ardito Barletta inherited a country in economic ruin and hugely indebted to the International Monetary Fund and the World Bank. Amid the economic crisis and Barletta's efforts to calm the country's creditors, street protests arose, and so did military repression. Meanwhile, Noriega's regime had fostered a well-hidden criminal economy that operated as a parallel source of income for the military and their allies, providing revenues from drugs and money laundering. Toward the end of the military dictatorship, a new wave of Chinese migrants arrived on the isthmus in the hope of migrating to the United States. The smuggling of Chinese became an enormous business, with revenues of up to 200 million dollars for Noriega's regime (see Mon 167). The military dictatorship assassinated or tortured more than one hundred Panamanians and forced at least a hundred more dissidents into exile. (see Zárate 15). Noriega's regime was supported by the United States and it began playing a double role in Central America. While the Contadora group, an initiative launched by the foreign ministers of various Latin American nations including Panama's, conducted diplomatic efforts to achieve peace in the region, Noriega supplied Nicaraguan Contras and other guerrillas in the region with weapons and ammunition on behalf of the CIA. On June 6, 1987, the recently retired Colonel Roberto Díaz Herrera, resentful that Noriega had broken the agreed-upon "Torrijos Plan" of succession that would have made him the chief of the military after Noriega, decided to denounce the regime. He revealed details of electoral fraud, accused Noriega of planning Torrijos's death and declared that Torrijos had received 12 million dollars from the Shah of Iran for giving the exiled Iranian leader asylum. He also accused Noriega of the assassination by decapitation of then-opposition leader, Dr. Hugo Spadafora. On the night of June 9, 1987, the Cruzada Civilista ("Civic Crusade") was created and began organizing actions of civil disobedience. The Crusade called for a general strike. In response, the military suspended constitutional rights and declared a state of emergency in the country. On July 10, the Civic Crusade called for a massive demonstration that was violently repressed by the "Dobermans", the military's special riot control unit. That day, later known as El Viernes Negro ("Black Friday"), left six hundred people injured and another six hundred detained, many of whom were later tortured and raped. United States President Ronald Reagan began a series of sanctions against the military regime. The United States froze economic and military assistance to Panama in the middle of 1987 in response to the domestic political crisis in Panama and an attack on the US embassy. The sanctions failed to oust Noriega, but severely hurt Panama's economy. Panama's gross domestic product (GDP) declined almost 25 percent between 1987 and 1989. On February 5, 1988, General Manuel Antonio Noriega was accused of drug trafficking by federal juries in Tampa and Miami. Human Rights Watch wrote in its 1989 report: "Washington turned a blind eye to abuses in Panama for many years until concern over drug trafficking prompted indictments of the general [Noriega] by two grand juries in Florida in February 1988". In April 1988, US President Ronald Reagan invoked the International Emergency Economic Powers Act, freezing Panamanian government assets in all US organizations. In May 1989 Panamanians voted overwhelmingly for the anti-Noriega candidates. The Noriega regime promptly annulled the election and embarked on a new round of repression. US invasion (1989) The United States invaded Panama on December 20, 1989, codenamed Operation Just Cause. The U.S. stated the operation was "necessary to safeguard the lives of U.S. citizens in Panama, defend democracy and human rights, combat drug trafficking, and secure the neutrality of the Panama Canal as required by the Torrijos–Carter Treaties". The US reported 23 servicemen killed and 324 wounded, with the number of Panamanian soldiers killed estimated at around 450. The estimates for civilians killed in the conflict ranges from 200 to 4,000. The United Nations put the Panamanian civilian death toll at 500, Americas Watch estimated 300, the United States gave a figure of 202 civilians killed and former US attorney general Ramsey Clark estimated 4,000 deaths. It represented the largest United States military operation since the Vietnam War. The number of US civilians (and their dependents), who had worked for the Panama Canal Commission and the US military, and were killed by the Panamanian Defense Forces, has never been fully disclosed. On December 29, the United Nations General Assembly approved a resolution calling the intervention in Panama a "flagrant violation of international law and of the independence, sovereignty and territorial integrity of the States". A similar resolution was vetoed in the Security Council by the United States, the United Kingdom, and France. Noriega was captured and flown to Miami to be tried. The conflict ended on January 31, 1990. The urban population, many living below the poverty level, was greatly affected by the 1989 intervention. As pointed out in 1995 by a UN Technical Assistance Mission to Panama, the fighting displaced 20,000 people. The most heavily affected district was the El Chorrillo area of Panama City, where several blocks of apartments were completely destroyed. The economic damage caused by the fighting has been estimated at between 1.5 and 2 billion dollars. Most Panamanians supported the intervention. Post-intervention era Panama's Electoral Tribunal moved quickly to restore civilian constitutional government, reinstated the results of the May 1989 election on December 27, 1989, and confirmed the victory of President Guillermo Endara and Vice Presidents Guillermo Ford and Ricardo Arias Calderón. During its five-year term, the often-fractious government struggled to meet the public's high expectations. Its new police force was a major improvement over its predecessor but was not fully able to deter crime. Ernesto Pérez Balladares was sworn in as president on September 1, 1994, after an internationally monitored election campaign. Perez Balladares ran as the candidate for a three-party coalition dominated by the Democratic Revolutionary Party (PRD), the erstwhile political arm of military dictatorships. Perez Balladares worked skillfully during the campaign to rehabilitate the PRD's image, emphasizing the party's populist Torrijos roots rather than its association with Noriega. He won the election with only 33 percent of the vote when the major non-PRD forces splintered into competing factions. His administration carried out economic reforms and often worked closely with the US on implementation of the Canal treaties. On September 1, 1999, Mireya Moscoso, the widow of former President Arnulfo Arias Madrid, took office after defeating PRD candidate Martín Torrijos, son of Omar Torrijos, in a free and fair election. During her administration, Moscoso attempted to strengthen social programs, especially for child and youth development, protection, and general welfare. Moscoso's administration successfully handled the Panama Canal transfer and was effective in the administration of the Canal. The PRD's Martin Torrijos won the presidency and a legislative majority in the National Assembly in 2004. Torrijos ran his campaign on a platform of, among other pledges, a "zero tolerance" for corruption, a problem endemic to the Moscoso and Perez Balladares administrations. After taking office, Torrijos passed a number of laws which made the government more transparent. He formed a National Anti-Corruption Council whose members represented the highest levels of government and civil society, labor organizations, and religious leadership. In addition, many of his closest Cabinet ministers were non-political technocrats known for their support for the Torrijos government's anti-corruption aims. Despite the Torrijos administration's public stance on corruption, many high-profile cases, particularly involving political or business elites, were never acted upon. Conservative supermarket magnate Ricardo Martinelli was elected to succeed Martin Torrijos with a landslide victory in the May 2009 Panamanian general election. Martinelli's business credentials drew voters worried by slowing growth during the Great Recession. Standing for the four-party opposition Alliance for Change, Martinelli gained 60 percent of the vote, against 37 percent for the candidate of the governing left-wing Democratic Revolutionary Party. On May 4, 2014, Vice President Juan Carlos Varela, candidate of the center-right Partido Panamenista (Party for Panama) won the 2014 presidential election with over 39 percent of the votes, against the party of his former political partner Ricardo Martinelli, Cambio Democrático, and their candidate José Domingo Arias. He was sworn in on July 1, 2014. On July 1, 2019 Laurentino Cortizo took possession of the presidency. Cortizo was the candidate of Democratic Revolution Party (PRD) in May 2019 presidential election. Geography Panama is located in Central America, bordering both the Caribbean Sea and the Pacific Ocean, between Colombia and Costa Rica. It mostly lies between latitudes 7° and 10°N, and longitudes 77° and 83°W (a small area lies west of 83°). Its location on the Isthmus of Panama is strategic. By 2000, Panama controlled the Panama Canal which connects the Atlantic Ocean and the Caribbean Sea to the north of the Pacific Ocean. Panama's total area is . The dominant feature of Panama's geography is the central spine of mountains and hills that forms the continental divide. The divide does not form part of the great mountain chains of North America, and only near the Colombian border are there highlands related to the Andean system of South America. The spine that forms the divide is the highly eroded arch of an uplift from the sea bottom, in which peaks were formed by volcanic intrusions. The mountain range of the divide is called the Cordillera de Talamanca near the Costa Rican border. Farther east it becomes the Serranía de Tabasará, and the portion of it closer to the lower saddle of the isthmus, where the Panama Canal is located, is often called the Sierra de Veraguas. As a whole, the range between Costa Rica and the canal is generally referred to by geographers as the Cordillera Central. The highest point in the country is the Volcán Barú, which rises to . A nearly impenetrable jungle forms the Darién Gap between Panama and Colombia where Colombian guerrillas and drug dealers operate and sometimes take hostages. This and unrest, and forest protection movements, create a break in the Pan-American Highway, which otherwise forms a complete road from Alaska to Patagonia. Panama's wildlife is the most diverse in Central America. It is home to many South American species as well as to North American wildlife. Waterways Nearly 500 rivers lace Panama's rugged landscape. Mostly unnavigable, many originate as swift highland streams, meander in valleys, and form coastal deltas. However, the Río Chagres (Chagres River), located in central Panama, is one of the few wide rivers and a source of hydroelectric power. The | 1821, by the residents of Azuero without backing from Panama City to declare their separation from the Spanish Empire. In both Veraguas and the capital this act was met with disdain, although on differing levels. To Veraguas, it was the ultimate act of treason, while to the capital, it was seen as inefficient and irregular, and furthermore forced them to accelerate their plans. Nevertheless, the Grito was a sign, on the part of the residents of Azuero, of their antagonism toward the independence movement in the capital. Those in the capital region in turn regarded the Azueran movement with contempt, since the separatists in Panama City believed that their counterparts in Azuero were fighting not only for independence from Spain, but also for their right to self-rule apart from Panama City once the Spaniards were gone. It was seen as a risky move on the part of Azuero, which lived in fear of Colonel José Pedro Antonio de Fábrega y de las Cuevas (1774–1841). The colonel was a staunch loyalist and had all of the isthmus' military supplies in his hands. They feared quick retaliation and swift retribution against the separatists. What they had counted on, however, was the influence of the separatists in the capital. Ever since October 1821, when the former Governor General, Juan de la Cruz Murgeón, left the isthmus on a campaign in Quito and left a colonel in charge, the separatists had been slowly converting Fábrega to the separatist side. So, by November 10, Fábrega was now a supporter of the independence movement. Soon after the separatist declaration of Los Santos, Fábrega convened every organization in the capital with separatist interests and formally declared the city's support for independence. No military repercussions occurred because of skillful bribing of royalist troops. Post-colonial Panama In the 80 years following independence from Spain, Panama was a subdivision of Gran Colombia, after voluntarily joining the country at the end of 1821. The people of the isthmus made over 80 attempts to secede from Colombia. They came close to success in 1831, then again during the Thousand Days' War of 1899–1902, understood among indigenous Panamanians as a struggle for land rights under the leadership of Victoriano Lorenzo. The US intent to influence the area, especially the Panama Canal's construction and control, led to the separation of Panama from Colombia in 1903 and its establishment as a nation. When the Senate of Colombia rejected the Hay–Herrán Treaty on January 22, 1903, the United States decided to support and encourage the Panamanian separatist movement In November 1903 Panama, tacitly supported by the United States, proclaimed its independence and concluded the Hay–Bunau-Varilla Treaty with the United States without the presence of a single Panamanian. Philippe Bunau-Varilla, a French engineer and lobbyist represented Panama even though Panama's president and a delegation had arrived in New York to negotiate the treaty. The treaty was quickly drafted and signed the night before the Panamanian delegation arrived in Washington. Mr. Bunau-Varilla was in the employ of the French Canal company that had failed and was now bankrupt. The treaty granted rights to the United States "as if it were sovereign" in a zone roughly wide and long. In that zone, the US would build a canal, then administer, fortify, and defend it "in perpetuity". In 1914 the United States completed the existing canal. Because of the strategic importance of the canal during World War II, the US extensively fortified access to it. From 1903 to 1968, Panama was a constitutional democracy dominated by a commercially oriented oligarchy. During the 1950s, the Panamanian military began to challenge the oligarchy's political hegemony. The early 1960s saw also the beginning of sustained pressure in Panama for the renegotiation of the Hay–Bunau-Varilla Treaty, including riots that broke out in early 1964, resulting in widespread looting and dozens of deaths, and the evacuation of the American embassy. Amid negotiations for the Robles–Johnson treaty, Panama held elections in 1968. The candidates were: Dr. Arnulfo Arias Madrid, Unión Nacional (National Union) Antonio González Revilla, Democracia Cristiana (Christian Democrats) Engr. David Samudio, Alianza del Pueblo (People's Alliance) who had the government's support. Arias Madrid was declared the winner of elections that were marked by violence and accusations of fraud against Alianza del Pueblo. On October 1, 1968, Arias Madrid took office as president of Panama, promising to lead a government of "national union" that would end the reigning corruption and pave the way for a new Panama. A week and a half later, on October 11, 1968, the National Guard (Guardia Nacional) ousted Arias and initiated the downward spiral that would culminate with the United States' invasion in 1989. Arias, who had promised to respect the hierarchy of the National Guard, broke the pact and started a large restructuring of the Guard. To preserve the Guard's and his vested interests, Lieutenant Colonel Omar Torrijos Herrera and Major Boris Martínez commanded another military coup against a civilian government in Panamanian republican history. (The action was reminiscent of the 1940s when strong man Colonel Jose Remon removed three duly elected presidents. Remon finally ran for president himself in 1952. He controlled the National Guard which abused the opposition during the campaign and even stole election boxes on election day.) The military justified itself by declaring that Arias Madrid was trying to install a dictatorship, and promised a return to constitutional rule. In the meantime, the Guard began a series of populist measures that would gain support for the coup. Among them were: Price freezing on food, medicine and other goods until January 31, 1969 rent level freeze legalization of the permanence of squatting families in boroughs surrounding the historic site of Panama Viejo Parallel to this, the military began a policy of repression against the opposition, who were labeled communists. The military appointed a Provisional Government Junta that was to arrange new elections. However, the National Guard would prove to be very reluctant to abandon power and soon began calling itself El Gobierno Revolucionario (The Revolutionary Government). Post-1970 Under Omar Torrijos's control, the military transformed the political and economic structure of the country, initiating massive coverage of social security services and expanding public education. The constitution was changed in 1972. To reform the constitution, the military created a new organization, the Assembly of Corregimiento Representatives, which replaced the National Assembly. The new assembly, also known as the Poder Popular (Power of the People), was composed of 505 members selected by the military with no participation from political parties, which the military had eliminated. The new constitution proclaimed Omar Torrijos as the Maximum Leader of the Panamanian Revolution, and conceded him unlimited power for six years, although, to keep a façade of constitutionality, Demetrio B. Lakas was appointed president for the same period. In 1981, Torrijos died in a plane crash. Torrijos' death altered the tone of Panama's political evolution. Despite the 1983 constitutional amendments which proscribed a political role for the military, the Panama Defense Force (PDF), as they were then known, continued to dominate Panamanian political life. By this time, General Manuel Antonio Noriega was firmly in control of both the PDF and the civilian government. In the 1984 elections, the candidates were Nicolás Ardito Barletta Vallarino, supported by the military in a union called UNADE Arnulfo Arias Madrid, for the opposition union ADO ex-General Rubén Darío Paredes, who had been forced to an early retirement by Noriega, running for Partido Nacionalista Popular PNP ("Popular Nationalist Party") Carlos Iván Zúñiga, running for Partido Acción Popular (PAPO) meaning "Popular Action Party" Barletta was declared the winner of elections that had been clearly won by Arias. Ardito Barletta inherited a country in economic ruin and hugely indebted to the International Monetary Fund and the World Bank. Amid the economic crisis and Barletta's efforts to calm the country's creditors, street protests arose, and so did military repression. Meanwhile, Noriega's regime had fostered a well-hidden criminal economy that operated as a parallel source of income for the military and their allies, providing revenues from drugs and money laundering. Toward the end of the military dictatorship, a new wave of Chinese migrants arrived on the isthmus in the hope of migrating to the United States. The smuggling of Chinese became an enormous business, with revenues of up to 200 million dollars for Noriega's regime (see Mon 167). The military dictatorship assassinated or tortured more than one hundred Panamanians and forced at least a hundred more dissidents into exile. (see Zárate 15). Noriega's regime was supported by the United States and it began playing a double role in Central America. While the Contadora group, an initiative launched by the foreign ministers of various Latin American nations including Panama's, conducted diplomatic efforts to achieve peace in the region, Noriega supplied Nicaraguan Contras and other guerrillas in the region with weapons and ammunition on behalf of the CIA. On June 6, 1987, the recently retired Colonel Roberto Díaz Herrera, resentful that Noriega had broken the agreed-upon "Torrijos Plan" of succession that would have made him the chief of the military after Noriega, decided to denounce the regime. He revealed details of electoral fraud, accused Noriega of planning Torrijos's death and declared that Torrijos had received 12 million dollars from the Shah of Iran for giving the exiled Iranian leader asylum. He also accused Noriega of the assassination by decapitation of then-opposition leader, Dr. Hugo Spadafora. On the night of June 9, 1987, the Cruzada Civilista ("Civic Crusade") was created and began organizing actions of civil disobedience. The Crusade called for a general strike. In response, the military suspended constitutional rights and declared a state of emergency in the country. On July 10, the Civic Crusade called for a massive demonstration that was violently repressed by the "Dobermans", the military's special riot control unit. That day, later known as El Viernes Negro ("Black Friday"), left six hundred people injured and another six hundred detained, many of whom were later tortured and raped. United States President Ronald Reagan began a series of sanctions against the military regime. The United States froze economic and military assistance to Panama in the middle of 1987 in response to the domestic political crisis in Panama and an attack on the US embassy. The sanctions failed to oust Noriega, but severely hurt Panama's economy. Panama's gross domestic product (GDP) declined almost 25 percent between 1987 and 1989. On February 5, 1988, General Manuel Antonio Noriega was accused of drug trafficking by federal juries in Tampa and Miami. Human Rights Watch wrote in its 1989 report: "Washington turned a blind eye to abuses in Panama for many years until concern over drug trafficking prompted indictments of the general [Noriega] by two grand juries in Florida in February 1988". In April 1988, US President Ronald Reagan invoked the International Emergency Economic Powers Act, freezing Panamanian government assets in all US organizations. In May 1989 Panamanians voted overwhelmingly for the anti-Noriega candidates. The Noriega regime promptly annulled the election and embarked on a new round of repression. US invasion (1989) The United States invaded Panama on December 20, 1989, codenamed Operation Just Cause. The U.S. stated the operation was "necessary to safeguard the lives of U.S. citizens in Panama, defend democracy and human rights, combat drug trafficking, and secure the neutrality of the Panama Canal as required by the Torrijos–Carter Treaties". The US reported 23 servicemen killed and 324 wounded, with the number of Panamanian soldiers killed estimated at around 450. The estimates for civilians killed in the conflict ranges from 200 to 4,000. The United Nations put the Panamanian civilian death toll at 500, Americas Watch estimated 300, the United States gave a figure of 202 civilians killed and former US attorney general Ramsey Clark estimated 4,000 deaths. It represented the largest United States military operation since the Vietnam War. The number of US civilians (and their dependents), who had worked for the Panama Canal Commission and the US military, and were killed by the Panamanian Defense Forces, has never been fully disclosed. On December 29, the United Nations General Assembly approved a resolution calling the intervention in Panama a "flagrant violation of international law and of the independence, sovereignty and territorial integrity of the States". A similar resolution was vetoed in the Security Council by the United States, the United Kingdom, and France. Noriega was captured and flown to Miami to be tried. The conflict ended on January 31, 1990. The urban population, many living below the poverty level, was greatly affected by the 1989 intervention. As pointed out in 1995 by a UN Technical Assistance Mission to Panama, the fighting displaced 20,000 people. The most heavily affected district was the El Chorrillo area of Panama City, where several blocks of apartments were completely destroyed. The economic damage caused by the fighting has been estimated at between 1.5 and 2 billion dollars. Most Panamanians supported the intervention. Post-intervention era Panama's Electoral Tribunal moved quickly to restore civilian constitutional government, reinstated the results of the May 1989 election on December 27, 1989, and confirmed the victory of President Guillermo Endara and Vice Presidents Guillermo Ford and Ricardo Arias Calderón. During its five-year term, the often-fractious government struggled to meet the public's high expectations. Its new police force was a major improvement over its predecessor but was not fully able to deter crime. Ernesto Pérez Balladares was sworn in as president on September 1, 1994, after an internationally monitored election campaign. Perez Balladares ran as the candidate for a three-party coalition dominated by the Democratic Revolutionary Party (PRD), the erstwhile political arm of military dictatorships. Perez Balladares worked skillfully during the campaign to rehabilitate the PRD's image, emphasizing the party's populist Torrijos roots rather than its association with Noriega. He won the election with only 33 percent of the vote when the major non-PRD forces splintered into competing factions. His administration carried out economic reforms and often worked closely with the US on implementation of the Canal treaties. On September 1, 1999, Mireya Moscoso, the widow of former President Arnulfo Arias Madrid, took office after defeating PRD candidate Martín Torrijos, son of Omar Torrijos, in a free and fair election. During her administration, Moscoso attempted to strengthen social programs, especially for child and youth development, protection, and general welfare. Moscoso's administration successfully handled the Panama Canal transfer and was effective in the administration of the Canal. The PRD's Martin Torrijos won the presidency and a legislative majority in the National Assembly in 2004. Torrijos ran his campaign on a platform of, among other pledges, a "zero tolerance" for corruption, a problem endemic to the Moscoso and Perez Balladares administrations. After taking office, Torrijos passed a number of laws which made the government more transparent. He formed a National Anti-Corruption Council whose members represented the highest levels of government and civil society, labor organizations, and religious leadership. In addition, many of his closest Cabinet ministers were non-political technocrats known for their support for the Torrijos government's anti-corruption aims. Despite the Torrijos administration's public stance on corruption, many high-profile cases, particularly involving political or business elites, were never acted upon. Conservative supermarket magnate Ricardo Martinelli was elected to succeed Martin Torrijos with a landslide victory in the May 2009 Panamanian general election. Martinelli's business credentials drew voters worried by slowing growth during the Great Recession. Standing for the four-party opposition Alliance for Change, Martinelli gained 60 percent of the vote, against 37 percent for the candidate of the governing left-wing Democratic Revolutionary Party. On May 4, 2014, Vice President Juan Carlos Varela, candidate of the center-right Partido Panamenista (Party for Panama) won the 2014 presidential election with over 39 percent of the votes, against the party of his former political partner Ricardo Martinelli, Cambio Democrático, and their candidate José Domingo Arias. He was sworn in on July 1, 2014. On July 1, 2019 Laurentino Cortizo took possession of the presidency.

any expression that do not involve the indeterminates, and represent mathematical objects that can be added and multiplied. Two polynomial expressions are considered as defining the same polynomial if they may be transformed, one to the other, by applying the usual properties of commutativity, associativity and distributivity of addition and multiplication. For example and are two polynomial expressions that represent the same polynomial; so, one writes A polynomial in a single indeterminate can always be written (or rewritten) in the form where are constants that are called the coefficients of the polynomial, and is the indeterminate. The word "indeterminate" means that represents no particular value, although any value may be substituted for it. The mapping that associates the result of this substitution to the substituted value is a function, called a polynomial function. This can be expressed more concisely by using summation notation: That is, a polynomial can either be zero or can be written as the sum of a finite number of non-zero terms. Each term consists of the product of a number called the coefficient of the term and a finite number of indeterminates, raised to nonnegative integer powers. Classification The exponent on an indeterminate in a term is called the degree of that indeterminate in that term; the degree of the term is the sum of the degrees of the indeterminates in that term, and the degree of a polynomial is the largest degree of any term with nonzero coefficient. Because , the degree of an indeterminate without a written exponent is one. A term with no indeterminates and a polynomial with no indeterminates are called, respectively, a constant term and a constant polynomial. The degree of a constant term and of a nonzero constant polynomial is 0. The degree of the zero polynomial 0 (which has no terms at all) is generally treated as not defined (but see below). For example: is a term. The coefficient is , the indeterminates are and , the degree of is two, while the degree of is one. The degree of the entire term is the sum of the degrees of each indeterminate in it, so in this example the degree is . Forming a sum of several terms produces a polynomial. For example, the following is a polynomial: It consists of three terms: the first is degree two, the second is degree one, and the third is degree zero. Polynomials of small degree have been given specific names. A polynomial of degree zero is a constant polynomial, or simply a constant. Polynomials of degree one, two or three are respectively linear polynomials, quadratic polynomials and cubic polynomials. For higher degrees, the specific names are not commonly used, although quartic polynomial (for degree four) and quintic polynomial (for degree five) are sometimes used. The names for the degrees may be applied to the polynomial or to its terms. For example, the term in is a linear term in a quadratic polynomial. The polynomial 0, which may be considered to have no terms at all, is called the zero polynomial. Unlike other constant polynomials, its degree is not zero. Rather, the degree of the zero polynomial is either left explicitly undefined, or defined as negative (either −1 or −∞). The zero polynomial is also unique in that it is the only polynomial in one indeterminate that has an infinite number of roots. The graph of the zero polynomial, , is the x-axis. In the case of polynomials in more than one indeterminate, a polynomial is called homogeneous of if all of its non-zero terms have . The zero polynomial is homogeneous, and, as a homogeneous polynomial, its degree is undefined. For example, is homogeneous of degree 5. For more details, see Homogeneous polynomial. The commutative law of addition can be used to rearrange terms into any preferred order. In polynomials with one indeterminate, the terms are usually ordered according to degree, either in "descending powers of ", with the term of largest degree first, or in "ascending powers of ". The polynomial is written in descending powers of . The first term has coefficient , indeterminate , and exponent . In the second term, the coefficient . The third term is a constant. Because the degree of a non-zero polynomial is the largest degree of any one term, this polynomial has degree two. Two terms with the same indeterminates raised to the same powers are called "similar terms" or "like terms", and they can be combined, using the distributive law, into a single term whose coefficient is the sum of the coefficients of the terms that were combined. It may happen that this makes the coefficient 0. Polynomials can be classified by the number of terms with nonzero coefficients, so that a one-term polynomial is called a monomial, a two-term polynomial is called a binomial, and a three-term polynomial is called a trinomial. The term "quadrinomial" is occasionally used for a four-term polynomial. A real polynomial is a polynomial with real coefficients. When it is used to define a function, the domain is not so restricted. However, a real polynomial function is a function from the reals to the reals that is defined by a real polynomial. Similarly, an integer polynomial is a polynomial with integer coefficients, and a complex polynomial is a polynomial with complex coefficients. A polynomial in one indeterminate is called a univariate polynomial, a polynomial in more than one indeterminate is called a multivariate polynomial. A polynomial with two indeterminates is called a bivariate polynomial. These notions refer more to the kind of polynomials one is generally working with than to individual polynomials; for instance, when working with univariate polynomials, one does not exclude constant polynomials (which may result from the subtraction of non-constant polynomials), although strictly speaking, constant polynomials do not contain any indeterminates at all. It is possible to further classify multivariate polynomials as bivariate, trivariate, and so on, according to the maximum number of indeterminates allowed. Again, so that the set of objects under consideration be closed under subtraction, a study of trivariate polynomials usually allows bivariate polynomials, and so on. It is also common to say simply "polynomials in , and ", listing the indeterminates allowed. The evaluation of a polynomial consists of substituting a numerical value to each indeterminate and carrying out the indicated multiplications and additions. For polynomials in one indeterminate, the evaluation is usually more efficient (lower number of arithmetic operations to perform) using Horner's method: Arithmetic Addition and subtraction Polynomials can be added using the associative law of addition (grouping all their terms together into a single sum), possibly followed by reordering (using the commutative law) and combining of like terms. For example, if and then the sum can be reordered and regrouped as and then simplified to When polynomials are added together, the result is another polynomial. Subtraction of polynomials is similar. Multiplication Polynomials can also be multiplied. To expand the product of two polynomials into a sum of terms, the distributive law is repeatedly applied, which results in each term of one polynomial being multiplied by every term of the other. For example, if then Carrying out the multiplication in each term produces Combining similar terms yields which can be simplified to As in the example, the product of polynomials is always a polynomial. Composition Given a polynomial of a single variable and another polynomial of any number of variables, the composition is obtained by substituting each copy of the variable of the first polynomial by the second polynomial. For example, if and then A composition may be expanded to a sum of terms using the rules for multiplication and division of polynomials. The composition of two polynomials is another polynomial. Division The division of one polynomial by another is not typically a polynomial. Instead, such ratios are a more general family of objects, called rational fractions, rational expressions, or rational functions, depending on context. This is analogous to the fact that the ratio of two integers is a rational number, not necessarily an integer. For example, the fraction is not a polynomial, and it cannot be written as a finite sum of powers of the variable . For polynomials in one variable, there is a notion of Euclidean division of polynomials, generalizing the Euclidean division of integers. This notion of the division results in two polynomials, a quotient and a remainder , such that and . The quotient and remainder may be computed by any of several algorithms, including polynomial long division and synthetic division. When the denominator is monic and linear, that is, for some constant , then the polynomial remainder theorem asserts that the remainder of the division of by is the evaluation . In this case, the quotient may be computed by Ruffini's rule, a special case of synthetic division. Factoring All polynomials with coefficients in a unique factorization domain (for example, the integers or a field) also have a factored form in which the polynomial is | denotes, by convention, the result of substituting a for x in P. Thus, the polynomial P defines the function which is the polynomial function associated to P. Frequently, when using this notation, one supposes that a is a number. However, one may use it over any domain where addition and multiplication are defined (that is, any ring). In particular, if a is a polynomial then P(a) is also a polynomial. More specifically, when a is the indeterminate x, then the image of x by this function is the polynomial P itself (substituting x for x does not change anything). In other words, which justifies formally the existence of two notations for the same polynomial. Definition A polynomial expression is an expression that can be built from constants and symbols called variables or indeterminates by means of addition, multiplication and exponentiation to a non-negative integer power. The constants are generally numbers, but may be any expression that do not involve the indeterminates, and represent mathematical objects that can be added and multiplied. Two polynomial expressions are considered as defining the same polynomial if they may be transformed, one to the other, by applying the usual properties of commutativity, associativity and distributivity of addition and multiplication.

For polynomials in one indeterminate, the evaluation is usually more efficient (lower number of arithmetic operations to perform) using Horner's method: Arithmetic Addition and subtraction Polynomials can be added using the associative law of addition (grouping all their terms together into a single sum), possibly followed by reordering (using the commutative law) and combining of like terms. For example, if and then the sum can be reordered and regrouped as and then simplified to When polynomials are added together, the result is another polynomial. Subtraction of polynomials is similar. Multiplication Polynomials can also be multiplied. To expand the product of two polynomials into a sum of terms, the distributive law is repeatedly applied, which results in each term of one polynomial being multiplied by every term of the other. For example, if then Carrying out the multiplication in each term produces Combining similar terms yields which can be simplified to As in the example, the product of polynomials is always a polynomial. Composition Given a polynomial of a single variable and another polynomial of any number of variables, the composition is obtained by substituting each copy of the variable of the first polynomial by the second polynomial. For example, if and then A composition may be expanded to a sum of terms using the rules for multiplication and division of polynomials. The composition of two polynomials is another polynomial. Division The division of one polynomial by another is not typically a polynomial. Instead, such ratios are a more general family of objects, called rational fractions, rational expressions, or rational functions, depending on context. This is analogous to the fact that the ratio of two integers is a rational number, not necessarily an integer. For example, the fraction is not a polynomial, and it cannot be written as a finite sum of powers of the variable . For polynomials in one variable, there is a notion of Euclidean division of polynomials, generalizing the Euclidean division of integers. This notion of the division results in two polynomials, a quotient and a remainder , such that and . The quotient and remainder may be computed by any of several algorithms, including polynomial long division and synthetic division. When the denominator is monic and linear, that is, for some constant , then the polynomial remainder theorem asserts that the remainder of the division of by is the evaluation . In this case, the quotient may be computed by Ruffini's rule, a special case of synthetic division. Factoring All polynomials with coefficients in a unique factorization domain (for example, the integers or a field) also have a factored form in which the polynomial is written as a product of irreducible polynomials |
terephthalate, even though produced from two different monomers (ethylene glycol and terephthalic acid), is usually regarded as a homopolymer because only one type of repeat unit is formed. Ethylene-vinyl acetate contains more than one variety of repeat unit and is a copolymer. Some biological polymers are composed of a variety of different but structurally related monomer residues; for example, polynucleotides such as DNA are composed of four types of nucleotide subunits. {| class="wikitable" style="text-align:left; font-size:90%;" width="80%" |- | class="hintergrundfarbe6" align="center" colspan="4" |Homopolymers and copolymers (examples) |- style="vertical-align:top" class="hintergrundfarbe2" | | | | |- style="vertical-align:top" | Homopolymer polystyrene | Homopolymer polydimethylsiloxane, a silicone.

Microstructure The microstructure of a polymer (sometimes called configuration) relates to the physical arrangement of monomer residues along the backbone of the chain. These are the elements of polymer structure that require the breaking of a covalent bond in order to change. Various polymer structures can be produced depending on the monomers and reaction conditions: A polymer may consist of linear macromolecules containing each only one unbranched chain. In the case of unbranched polyethylene, this chain is a long-chain n-alkane. There are also branched macromolecules with a main chain and side chains, in the case of polyethylene the side chains would be alkyl groups. In particular unbranched macromolecules can be in the solid state semi-crystalline, crystalline chain sections highlighted red in the figure below. While branched and unbranched polymers are usually thermoplastics, many elastomers have a wide-meshed cross-linking between the "main chains". Close-meshed crosslinking, on the other hand, leads to thermosets. Cross-links and branches are shown as red dots in the figures. Highly branched polymers are amorphous and the molecules in the solid interact randomly. {| class="wikitable" style="text-align:center; font-size:90%;" width="60%" |- class="hintergrundfarbe2" | linear, unbranched macromolecule | branched macromolecule |semi-crystalline structure of an unbranched polymer | slightly cross-linked polymer (elastomer) | highly cross-linked polymer (thermoset) |} Polymer architecture An important microstructural feature of a polymer is its architecture and shape, which relates to the way branch points lead to a deviation from a simple linear chain. A branched polymer molecule is composed of a main chain with one or more substituent side chains or branches. Types of branched polymers include star polymers, comb polymers, polymer brushes, dendronized polymers, ladder polymers, and dendrimers. There exist also two-dimensional polymers (2DP) which are composed of topologically planar repeat units. A polymer's architecture affects many of its physical properties including solution viscosity, melt viscosity, solubility in various solvents, glass-transition temperature and the size of individual polymer coils in solution. A variety of techniques may be employed for the synthesis of a polymeric material with a range of architectures, for example living polymerization. Chain length A common means of expressing the length of a chain is the degree of polymerization, which quantifies the number of monomers incorporated into the chain. As with other molecules, a polymer's size may also be expressed in terms of molecular weight. Since synthetic polymerization techniques typically yield a statistical distribution of chain lengths, the molecular weight is expressed in terms of weighted averages. The number-average molecular weight (Mn) and weight-average molecular weight (Mw) are most commonly reported. The ratio of these two values (Mw / Mn) is the dispersity (Đ), which is commonly used to express the width of the molecular weight distribution. The physical properties of polymer strongly depend on the length (or equivalently, the molecular weight) of the polymer chain. One important example of the physical consequences of the molecular weight is the scaling of the viscosity (resistance to flow) in the melt. The influence of the weight-average molecular weight () on the melt viscosity () depends on whether the polymer is above or below the onset of entanglements. Below the entanglement molecular weight, , whereas above the entanglement molecular weight, . In the latter case, increasing the polymer chain length 10-fold would increase the viscosity over 1000 times. Increasing chain length furthermore tends to decrease chain mobility, increase strength and toughness, and increase the glass-transition temperature (Tg). This is a result of the increase in chain interactions such as van der Waals attractions and entanglements that come with increased chain length. These interactions tend to fix the individual chains more strongly in position and resist deformations and matrix breakup, both at higher stresses and higher temperatures. Monomer arrangement in copolymers Copolymers are classified either as statistical copolymers, alternating copolymers, block copolymers, graft copolymers or gradient copolymers. In the schematic figure below, Ⓐ and Ⓑ symbolize the two repeat units. {| class="wikitable" style="text-align:center; font-size:90%;" |- class="hintergrundfarbe2" | random copolymer | gradient copolymer | rowspan="2" | graft copolymer |- class="hintergrundfarbe2" | alternating copolymer | block copolymer |} Alternating copolymers possess two regularly alternating monomer residues: {{not a typo[AB]n}}. An example is the equimolar copolymer of styrene and maleic anhydride formed by free-radical chain-growth polymerization. A step-growth copolymer such as Nylon 66 can also be considered a strictly alternating copolymer of diamine and diacid residues, but is often described as a homopolymer with the dimeric residue of one amine and one acid as a repeat unit. Periodic copolymers have more than two species of monomer units in a regular sequence. Statistical copolymers have monomer residues arranged according to a statistical rule. A statistical copolymer in which the probability of finding a particular type of monomer residue at a particular point in the chain is independent of the types of surrounding monomer residue may be referred to as a truly random copolymer. For example, the chain-growth copolymer of vinyl chloride and vinyl acetate is random. Block copolymers have long sequences of different monomer units. Polymers with two or three blocks of two distinct chemical species (e.g., A and B) are called diblock copolymers and triblock copolymers, respectively. Polymers with three blocks, each of a different chemical species (e.g., A, B, and C) are termed triblock terpolymers. Graft or grafted copolymers contain side chains or branches whose repeat units have a different composition or configuration than the main chain. The branches are added on to a preformed main chain macromolecule. Monomers within a copolymer may be organized along the backbone in a variety of ways. A copolymer containing a controlled arrangement of monomers is called a sequence-controlled polymer. Alternating, periodic and block copolymers are simple examples of sequence-controlled polymers. Tacticity Tacticity describes the relative stereochemistry of chiral centers in neighboring structural units within a macromolecule. There are three types of tacticity: isotactic (all substituents on the same side), atactic (random placement of substituents), and syndiotactic (alternating placement of substituents). {| class="wikitable" style="text-align:center; font-size:90%;" width="60%" |- class="hintergrundfarbe2" | isotactic | syndiotactic | atactic (i. e. random) |} Morphology Polymer morphology generally describes the arrangement and microscale ordering of polymer chains in space. The macroscopic physical properties of a polymer are related to the interactions between the polymer chains. Disordered polymers: In the solid state, atactic polymers, polymers with a high degree of branching and random copolymers form amorphous (i.e. glassy structures). In melt and solution, polymers tend to form a constantly changing "statistical cluster", see freely-jointed-chain model. In the solid state, the respective conformations of the molecules are frozen. Hooking and entanglement of chain molecules lead to a "mechanical bond" between the chains. Intermolecular and intramolecular attractive forces only occur at sites where molecule segments are close enough to each other. The irregular structures of the molecules prevent a narrower arrangement. Linear polymers with periodic structure, low branching and stereoregularity (e. g. not atactic) have a semi-crystalline structure in the solid state. In simple polymers (such as polyethylene), the chains are present in the crystal in zigzag conformation. Several zigzag conformations form dense chain packs, called crystallites or lamellae. The lamellae are much thinner than the polymers are long (often about 10 nm). They are formed by more or less regular folding of one or more molecular chains. Amorphous structures exist between the lamellae. Individual molecules can lead to entanglements between the lamellae and can also be involved in the formation of two (or more) lamellae (chains than called tie molecules). Several lamellae form a superstructure, a spherulite, often with a diameter in the range of 0.05 to 1 mm. The type and arrangement of (functional) residues of the repeat units effects or determines the crystallinity and strength of the secondary valence bonds. In isotactic polypropylene, the molecules form a helix. Like the zigzag conformation, such helices allow a dense chain packing. Particularly strong intermolecular interactions occur when the residues of the repeating units allow the formation of hydrogen bonds, as in the case of p-aramid. The formation of strong intramolecular associations may produce diverse folded states of single linear chains with distinct circuit topology. Crystallinity and superstructure are always dependent on the conditions of their formation, see also: crystallization of polymers. Compared to amorphous structures, semi-crystalline structures lead to a higher stiffness, density, melting temperature and higher resistance of a polymer. Cross-linked polymers: Wide-meshed cross-linked polymers are elastomers and cannot be molten (unlike thermoplastics); heating cross-linked polymers only leads to decomposition. Thermoplastic elastomers, on the other hand, are reversibly "physically crosslinked" and can be molten. Block copolymers in which a hard segment of the polymer has a tendency to crystallize and a soft segment has an amorphous structure are one type of thermoplastic elastomers: the hard segments ensure wide-meshed, physical crosslinking. Crystallinity When applied to polymers, the term crystalline has a somewhat ambiguous usage. In some cases, the term crystalline finds identical usage to that used in conventional crystallography. For example, the structure of a crystalline protein or polynucleotide, such as a sample prepared for x-ray crystallography, may be defined in terms of a conventional unit cell composed of one or more polymer molecules with cell dimensions of hundreds of angstroms or more.

For example, the structure of a crystalline protein or polynucleotide, such as a sample prepared for x-ray crystallography, may be defined in terms of a conventional unit cell composed of one or more polymer molecules with cell dimensions of hundreds of angstroms or more. A synthetic polymer may be loosely described as crystalline if it contains regions of three-dimensional ordering on atomic (rather than macromolecular) length scales, usually arising from intramolecular folding or stacking of adjacent chains. Synthetic polymers may consist of both crystalline and amorphous regions; the degree of crystallinity may be expressed in terms of a weight fraction or volume fraction of crystalline material. Few synthetic polymers are entirely crystalline. The crystallinity of polymers is characterized by their degree of crystallinity, ranging from zero for a completely non-crystalline polymer to one for a theoretical completely crystalline polymer. Polymers with microcrystalline regions are generally tougher (can be bent more without breaking) and more impact-resistant than totally amorphous polymers. Polymers with a degree of crystallinity approaching zero or one will tend to be transparent, while polymers with intermediate degrees of crystallinity will tend to be opaque due to light scattering by crystalline or glassy regions. For many polymers, reduced crystallinity may also be associated with increased transparency. Chain conformation The space occupied by a polymer molecule is generally expressed in terms of radius of gyration, which is an average distance from the center of mass of the chain to the chain itself. Alternatively, it may be expressed in terms of pervaded volume, which is the volume spanned by the polymer chain and scales with the cube of the radius of gyration. The simplest theoretical models for polymers in the molten, amorphous state are ideal chains. Properties Polymer properties depend of their structure and they are divided into classes according to their physical basis. Many physical and chemical properties describe how a polymer behaves as a continuous macroscopic material. They are classified as bulk properties, or intensive properties according to thermodynamics. Mechanical properties The bulk properties of a polymer are those most often of end-use interest. These are the properties that dictate how the polymer actually behaves on a macroscopic scale. Tensile strength The tensile strength of a material quantifies how much elongating stress the material will endure before failure. This is very important in applications that rely upon a polymer's physical strength or durability. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping. In general, tensile strength increases with polymer chain length and crosslinking of polymer chains. Young's modulus of elasticity Young's modulus quantifies the elasticity of the polymer. It is defined, for small strains, as the ratio of rate of change of stress to strain. Like tensile strength, this is highly relevant in polymer applications involving the physical properties of polymers, such as rubber bands. The modulus is strongly dependent on temperature. Viscoelasticity describes a complex time-dependent elastic response, which will exhibit hysteresis in the stress-strain curve when the load is removed. Dynamic mechanical analysis or DMA measures this complex modulus by oscillating the load and measuring the resulting strain as a function of time. Transport properties Transport properties such as diffusivity describe how rapidly molecules move through the polymer matrix. These are very important in many applications of polymers for films and membranes. The movement of individual macromolecules occurs by a process called reptation in which each chain molecule is constrained by entanglements with neighboring chains to move within a virtual tube. The theory of reptation can explain polymer molecule dynamics and viscoelasticity. Phase behavior Crystallization and melting Depending on their chemical structures, polymers may be either semi-crystalline or amorphous. Semi-crystalline polymers can undergo crystallization and melting transitions, whereas amorphous polymers do not. In polymers, crystallization and melting do not suggest solid-liquid phase transitions, as in the case of water or other molecular fluids. Instead, crystallization and melting refer to the phase transitions between two solid states (i.e., semi-crystalline and amorphous). Crystallization occurs above the glass-transition temperature (Tg) and below the melting temperature (Tm). Glass transition All polymers (amorphous or semi-crystalline) go through glass transitions. The glass-transition temperature (Tg) is a crucial physical parameter for polymer manufacturing, processing, and use. Below Tg, molecular motions are frozen and polymers are brittle and glassy. Above Tg, molecular motions are activated and polymers are rubbery and viscous. The glass-transition temperature may be engineered by altering the degree of branching or crosslinking in the polymer or by the addition of plasticizers. Whereas crystallization and melting are first-order phase transitions, the glass transition is not. The glass transition shares features of second-order phase transitions (such as discontinuity in the heat capacity, as shown in the figure), but it is generally not considered a thermodynamic transition between equilibrium states. Mixing behavior In general, polymeric mixtures are far less miscible than mixtures of small molecule materials. This effect results from the fact that the driving force for mixing is usually entropy, not interaction energy. In other words, miscible materials usually form a solution not because their interaction with each other is |
to protect their economic profits. This includes the use of predatory pricing toward smaller competitors. For example, in the United States, Microsoft Corporation was initially convicted of breaking Anti-Trust Law and engaging in anti-competitive behavior in order to form one such barrier in United States v. Microsoft; after a successful appeal on technical grounds, Microsoft agreed to a settlement with the Department of Justice in which they were faced with stringent oversight procedures and explicit requirements designed to prevent this predatory behaviour. With lower barriers, new firms can enter the market again, making the long run equilibrium more like that of a competitive industry, with no economic profit for firms. If a government feels it is impractical to have a competitive market – such as in the case of a natural monopoly – it will sometimes try to regulate the existing uncompetitive market by controlling the price firms charge for their product. For example, the old AT&T (regulated) monopoly, which existed before the courts ordered its breakup, had to get government approval to raise its prices. The government examined the monopoly's costs to determine whether the monopoly should be able raise its price, and could reject the monopoly's application for a higher price if the cost did not justify it. Although a regulated firm will not have an economic profit as large as it would in an unregulated situation, it can still make profits well above a competitive firm in a truly competitive market. Results In a perfectly competitive market, the demand curve facing a firm is perfectly elastic. As mentioned above, the perfect competition model, if interpreted as applying also to short-period or very-short-period behaviour, is approximated only by markets of homogeneous products produced and purchased by very many sellers and buyers, usually organized markets for agricultural products or raw materials. In real-world markets, assumptions such as perfect information cannot be verified and are only approximated in organized double-auction markets where most agents wait and observe the behaviour of prices before deciding to exchange (but in the long-period interpretation perfect information is not necessary, the analysis only aims at determining the average around which market prices gravitate, and for gravitation to operate one does not need perfect information). In the absence of externalities and public goods, perfectly competitive equilibria are Pareto-efficient, i.e. no improvement in the utility of a consumer is possible without a worsening of the utility of some other consumer. This is called the First Theorem of Welfare Economics. The basic reason is that no productive factor with a non-zero marginal product is left unutilized, and the units of each factor are so allocated as to yield the same indirect marginal utility in all uses, a basic efficiency condition (if this indirect marginal utility were higher in one use than in other ones, a Pareto improvement could be achieved by transferring a small amount of the factor to the use where it yields a higher marginal utility). A simple proof assuming differentiable utility functions and production functions is the following. Let wj be the 'price' (the rental) of a certain factor j, let MPj1 and MPj2 be its marginal product in the production of goods 1 and 2, and let p1 and p2 be these goods' prices. In equilibrium these prices must equal the respective marginal costs MC1 and MC2; remember that marginal cost equals factor 'price' divided by factor marginal productivity (because increasing the production of good by one very small unit through an increase of the employment of factor j requires increasing the factor employment by 1/MPji and thus increasing the cost by wj/MPji, and through the condition of cost minimization that marginal products must be proportional to factor 'prices' it can be shown that the cost increase is the same if the output increase is obtained by optimally varying all factors). Optimal factor employment by a price-taking firm requires equality of factor rental and factor marginal revenue product, wj=piMPji, so we obtain p1=MC1=wj/MPj1, p2=MCj2=wj/MPj2. Now choose any consumer purchasing both goods, and measure his utility in such units that in equilibrium his marginal utility of money (the increase in utility due to the last unit of money spent on each good), MU1/p1=MU2/p2, is 1. Then p1=MU1, p2=MU2. The indirect marginal utility of the factor is the increase in the utility of our consumer achieved by an increase in the employment of the factor by one (very small) unit; this increase in utility through allocating the small increase in factor utilization to good 1 is MPj1MU1=MPj1p1=wj, and through allocating it to good 2 it is MPj2MU2=MPj2p2=wj again. With our choice of units the marginal utility of the amount of the factor consumed directly by the optimizing consumer is again w, so the amount supplied of the factor too satisfies the condition of optimal allocation. Monopoly violates this optimal allocation condition, because in a monopolized industry market price is above marginal cost, and this means that factors are underutilized in the monopolized industry, they have a higher indirect marginal utility than in their uses in competitive industries. Of course, this theorem is considered irrelevant by economists who do not believe that general equilibrium theory correctly predicts the functioning of market economies; but it is given great importance by neoclassical economists and it is the theoretical reason given by them for combating monopolies and for antitrust legislation. Profit In contrast to a monopoly or oligopoly, in perfect competition it is impossible for a firm to earn economic profit in the long run, which is to say that a firm cannot make any more money than is necessary to cover its economic costs. In order not to misinterpret this zero-long-run-profits thesis, it must be remembered that the term 'profit' is used in different ways: Neoclassical theory defines profit as what is left of revenue after all costs have been subtracted; including normal interest on capital plus the normal excess over it required to cover risk, and normal salary for managerial activity. This means that profit is calculated after the actors are compensated for their opportunity costs. Classical economists on the contrary define profit as what is left after subtracting costs except interest and risk coverage. Thus, the classical approach does not account for opportunity costs. Thus, if one leaves aside risk coverage for simplicity, the neoclassical zero-long-run-profit thesis would be re-expressed in classical parlance as profits coinciding with interest in the long period (i.e. the rate of profit tending to coincide with the rate of interest). Profits in the classical meaning do not necessarily disappear in the long period but tend to normal profit. With this terminology, if a firm is earning abnormal profit in the short term, this will act as a trigger for other firms to enter the market. As other firms enter the market, the market supply curve will shift out, causing prices to fall. Existing firms will react to this lower price by adjusting their capital stock downward. This adjustment will cause their marginal cost to shift to the left causing the market supply curve to shift inward. However, the net effect of entry by new firms and adjustment by existing firms will be to shift the supply curve outward. The market price will be driven down until all firms are earning normal profit only. It is important to note that perfect competition is a sufficient condition for allocative and productive efficiency, but it is not a necessary condition. Laboratory experiments in which participants have significant price setting power and little or no information about their counterparts consistently produce efficient results given the proper trading institutions. Shutdown point In the short run, a firm operating at a loss [R < TC (revenue less than total cost) or P < ATC (price less than unit cost)] must decide whether to continue to operate or temporarily shut down. The shutdown rule states "in the short run a firm should continue to operate if price exceeds average variable costs". Restated, the rule is that for a firm to continue producing in the short run it must earn sufficient revenue to cover its variable costs. The rationale for the rule is straightforward: By shutting down a firm avoids all variable costs. However, the firm must still pay fixed costs. Because fixed costs must be paid regardless of whether a firm operates they should not be considered in deciding whether to produce or shut down. Thus in determining whether to shut down a firm should compare total revenue to total variable costs (VC) rather than total costs (FC + VC). If the revenue the firm is receiving is greater than its total variable cost (R > VC), then the firm is covering all variable costs and there is additional revenue ("contribution"), which can be applied to fixed costs. (The size of the fixed costs is irrelevant as it is a sunk cost. The same consideration is used whether fixed costs are one dollar or one million dollars.) On the other hand, if VC > R then the firm is not covering its production costs and it should immediately shut down. The rule is conventionally stated in terms of price (average revenue) and average variable costs. The rules are equivalent (if one divides both sides of inequality TR > TVC by Q gives P > AVC). If the firm decides to operate, the firm will continue to produce where marginal revenue equals marginal costs because these conditions insure not only profit maximization (loss minimization) but also maximum contribution. Another way to state the rule is that a firm should compare the profits from operating to those realized if it shut down and select the option that produces the greater profit. A firm that is shut down is generating zero revenue and incurring no variable costs. However, the firm still has to pay fixed cost. So the firm's profit equals fixed costs or −FC. An operating firm is generating revenue, incurring variable costs and paying fixed costs. The operating firm's profit is R − VC − FC. The firm should continue to operate if R − VC − FC ≥ −FC, which simplified is R ≥ VC. The difference between revenue, R, and variable costs, VC, is the contribution to fixed costs and any contribution is better than none. Thus, if R ≥ VC then firm should operate. If R < VC the firm should shut down. A decision to shut down means that the firm is temporarily suspending production. It does not mean that the firm is going out of business (exiting the | quantity in that range. Technically the SR supply curve is a discontinuous function composed of the segment of the MC curve at and above minimum of the average variable cost curve and a segment that runs on the vertical axis from the origin to but not including a point at the height of the minimum average variable cost. Criticisms The use of the assumption of perfect competition as the foundation of price theory for product markets is often criticized as representing all agents as passive, thus removing the active attempts to increase one's welfare or profits by price undercutting, product design, advertising, innovation, activities that – the critics argue – characterize most industries and markets. These criticisms point to the frequent lack of realism of the assumptions of product homogeneity and impossibility to differentiate it, but apart from this, the accusation of passivity appears correct only for short-period or very-short-period analyses, in long-period analyses the inability of price to diverge from the natural or long-period price is due to active reactions of entry or exit. Some economists have a different kind of criticism concerning perfect competition model. They are not criticizing the price taker assumption because it makes economic agents too "passive", but because it then raises the question of who sets the prices. Indeed, if everyone is price taker, there is the need for a benevolent planner who gives and sets the prices, in other word, there is a need for a "price maker". Therefore, it makes the perfect competition model appropriate not to describe a decentralized "market" economy but a centralized one. This in turn means that such kind of model has more to do with communism than capitalism. Another frequent criticism is that it is often not true that in the short run differences between supply and demand cause changes in price; especially in manufacturing, the more common behaviour is alteration of production without nearly any alteration of price. The critics of the assumption of perfect competition in product markets seldom question the basic neoclassical view of the working of market economies for this reason. The Austrian School insists strongly on this criticism, and yet the neoclassical view of the working of market economies as fundamentally efficient, reflecting consumer choices and assigning to each agent his contribution to social welfare, is esteemed to be fundamentally correct. Some non-neoclassical schools, like Post-Keynesians, reject the neoclassical approach to value and distribution, but not because of their rejection of perfect competition as a reasonable approximation to the working of most product markets; the reasons for rejection of the neoclassical 'vision' are different views of the determinants of income distribution and of aggregated demand. In particular, the rejection of perfect competition does not generally entail the rejection of free competition as characterizing most product markets; indeed it has been argued that competition is stronger nowadays than in 19th century capitalism, owing to the increasing capacity of big conglomerate firms to enter any industry: therefore the classical idea of a tendency toward a uniform rate of return on investment in all industries owing to free entry is even more valid today; and the reason why General Motors, Exxon or Nestlé do not enter the computers or pharmaceutical industries is not insurmountable barriers to entry but rather that the rate of return in the latter industries is already sufficiently in line with the average rate of return elsewhere as not to justify entry. On this few economists, it would seem, would disagree, even among the neoclassical ones. Thus when the issue is normal, or long-period, product prices, differences on the validity of the perfect competition assumption do not appear to imply important differences on the existence or not of a tendency of rates of return toward uniformity as long as entry is possible, and what is found fundamentally lacking in the perfect competition model is the absence of marketing expenses and innovation as causes of costs that do enter normal average cost. The issue is different with respect to factor markets. Here the acceptance or denial of perfect competition in labour markets does make a big difference to the view of the working of market economies. One must distinguish neoclassical from non-neoclassical economists. For the former, absence of perfect competition in labour markets, e.g. due to the existence of trade unions, impedes the smooth working of competition, which if left free to operate would cause a decrease of wages as long as there were unemployment, and would finally ensure the full employment of labour: labour unemployment is due to absence of perfect competition in labour markets. Most non-neoclassical economists deny that a full flexibility of wages would ensure the full employment of labour and find a stickiness of wages an indispensable component of a market economy, without which the economy would lack the regularity and persistence indispensable to its smooth working. This was, for example, John Maynard Keynes's opinion. Particularly radical is the view of the Sraffian school on this issue: the labour demand curve cannot be determined hence a level of wages ensuring the equality between supply and demand for labour does not exist, and economics should resume the viewpoint of the classical economists, according to whom competition in labour markets does not and cannot mean indefinite price flexibility as long as supply and demand are unequal, it only means a tendency to equality of wages for similar work, but the level of wages is necessarily determined by complex sociopolitical elements; custom, feelings of justice, informal allegiances to classes, as well as overt coalitions such as trade unions, far from being impediments to a smooth working of labour markets that would be able to determine wages even without these elements, are on the contrary indispensable because without them there would be no way to determine wages. Equilibrium in perfect competition Equilibrium in perfect competition is the point where market demands will be equal to market supply. A firm's price will be determined at this point. In the short run, equilibrium will be affected by demand. In the long run, both demand and supply of a product will affect the equilibrium in perfect competition. A firm will receive only normal profit in the long run at the equilibrium point. As it is well known, requirements for firm's cost-curve under perfect competition is for the slope to move upwards after a certain amount is produced. This amount is small enough to leave a sufficiently large number of firms in the field (for any given total outputs in the industry) for the conditions of perfect competition to be preserved. For the short-run, the supply of some factors are assumed to be fixed and as the price of the other factors are given, costs per unit must necessarily rise after a certain point. From a theoretical point of view, given the assumptions that there will be a tendency for continuous growth in size for firms, long-period static equilibrium alongside perfect competition may be incompatible.

paper. For Holland, a miracle need only be an extraordinary and beneficial coincidence interpreted religiously. Brian Davies notes that even if we can establish that a miracle has occurred, it is hard to see what this is supposed to prove. For it is possible that they arise due to agencies which are unusual and powerful, but not divine. Afterlife World religions put forth various theories which affirm life after death and different kinds of postmortem existence. This is often tied to belief in an immortal individual soul or self (Sanskrit: atman) separate from the body which survives death, as defended by Plato, Descartes, Monotheistic religions like Christianity and many Indian philosophers. This view is also a position on the mind body problem, mainly, dualism. This view then must show not only that dualism is true and that souls exist, but also that souls survive death. As Kant famously argued, the mere existence of a soul does not prove its immortality, for one could conceive that a soul, even if it is totally simple, could still fade away or lose its intensity. H. H. Price is one modern philosopher who has speculated at length about what it would be like to be a disembodied soul after death. One major issue with soul beliefs is that since personhood is closely tied to one's physical body, it seems difficult to make sense of a human being existing apart from their body. A further issue is with continuity of personal identity, that is, it is not easy to account for the claim that the person that exists after bodily death is the same person that existed before. Bertrand Russell put forth the general scientific argument against the afterlife as follows: Persons are part of the everyday world with which science is concerned, and the conditions which determine their existence are discoverable...we know that the brain is not immortal, and that the organized energy of a living body becomes, as it were, demobilized at death and therefore not available for collective action. All the evidence goes to show that what we regard as our mental life is bound up with brain structure and organized bodily energy. Therefore it is rational to suppose that mental life ceases when bodily life ceases. The argument is only one of probability, but it is as strong as those upon which most scientific conclusions are based. Contra Russell, J. M. E. McTaggart argues that people have no scientific proof that the mind is dependent on the body in this particular way. As Rowe notes, the fact that the mind depends on the functions of the body while one is alive is not necessarily proof that the mind will cease functioning after death just as a person trapped in a room while depending on the windows to see the outside world might continue to see even after the room ceases to exist. Buddhism is one religion which, while affirming postmortem existence (through rebirth), denies the existence of individual souls and instead affirms a deflationary view of personal identity, termed not-self (anatta). While physicalism has generally been seen as hostile to notions of an afterlife, this need not be the case. Abrahamic religions like Christianity have traditionally held that life after death will include the element of bodily resurrection. One objection to this view is that it seems difficult to account for personal continuity, at best, a resurrected body is a replica of the resurrected person not the same person. One response is the constitution view of persons, which says persons are constituted by their bodies and by a "first-person perspective", the capacity to think of oneself as oneself. In this view, what is resurrected is that first person perspective, or both the person's body and that perspective. An objection to this view is that it seems difficult to differentiate one person's first person perspective from another person's without reference to temporal and spatial relations. Peter van Inwagen meanwhile, offers the following theory: Perhaps at the moment of each man's death, God removes his corpse and replaces it with a simulacrum which is what is burned or rots. Or perhaps God is not quite so wholesale as this: perhaps He removes for "safekeeping" only the "core person"—the brain and central nervous system—or even some special part of it. These are details. (van Inwagen 1992: 245–46) This view shows how some positions on the nature of the afterlife are closely tied to and sometimes completely depend upon theistic positions. This close connection between the two views was made by Kant, who argued that one can infer an afterlife from belief in a just God who rewards persons for their adherence to moral law. Other discussions on the philosophy of the afterlife deal with phenomena such as near death experiences, reincarnation research, and other parapsychological events and hinge on whether naturalistic explanations for these phenomena is enough to explain them or not. Such discussions are associated with philosophers like William James, Henry Sidgwick, C.D. Broad, and H.H. Price. Diversity and pluralism The issue of how one is to understand religious diversity and the plurality of religious views and beliefs has been a central concern of the philosophy of religion. There are various philosophical positions regarding how one is to make sense of religious diversity, including exclusivism, inclusivism, pluralism, relativism, atheism or antireligion and agnosticism. Religious exclusivism is the claim that only one religion is true and that others are wrong. To say that a religion is exclusivistic can also mean that salvation or human freedom is only attainable by the followers of one's religion. This view tends to be the orthodox view of most monotheistic religions, such as Christianity and Islam, though liberal and modernist trends within them might differ. William L Rowe outlines two problems with this view. The first problem is that it is easy to see that if this is true, a large portion of humanity is excluded from salvation and it is hard to see how a loving god would desire this. The second problem is that once we become acquainted with the saintly figures and virtuous people in other religions, it can be difficult to see how we could say they are excluded from salvation just because they are not part of our religion. A different view is inclusivism, which is the idea that "one's own tradition alone has the whole truth but that this truth is nevertheless partially reflected in other traditions." An inclusivist might maintain that their religion is privileged, they can also hold that other religious adherents have fundamental truths and even that they will be saved or liberated. The Jain view of Anekantavada ('many-sidedness') has been interpreted by some as a tolerant view which is an inclusive acceptance of the partial truth value of non-Jain religious ideas. As Paul Dundas notes, the Jains ultimately held the thesis that Jainism is the final truth, while other religions only contain partial truths. Other scholars such as Kristin Beise Kiblinger have also argued that some of the Buddhist traditions include inclusivist ideas and attitudes. In the modern Western study of religion, the work of Ninian Smart has also been instrumental in representing a more diverse understanding of religion and religious pluralism. Smart's view is that there are genuine differences between religions. Pluralism is the view that all religions are equally valid responses to the divine and that they are all valid paths to personal transformation. This approach is taken by John Hick, who has developed a pluralistic view which synthesizes components of various religious traditions. Hick promotes an idea of a noumenal sacred reality which different religions provide us access to. Hick defines his view as "the great world faiths embody different perceptions and conceptions of, and correspondingly different responses to, the Real or the Ultimate." For Hick, all religions are true because they all allow us to encounter the divine reality, even if they have different deities and conceptions of it. Rowe notes that a similar idea is proposed by Paul Tillich's concept of Being-itself. The view of perennialism is that there is a single or core truth or experience which is shared by all religions even while they use different terms and language to express it. This view is espoused by the likes of Aldous Huxley, the thinkers of the Traditionalist School as well as Neo-Vedanta. Yet another way of responding to the conflicting truth claims of religions is Relativism. Joseph Runzo., one of its most prominent defenders, has argued for henofideism which states that the truth of a religious worldview is relative to each community of adherents. Thus while religions have incompatible views, each one is individually valid as they emerge from individual experiences of a plurality of phenomenal divine realities. According to Runzo, this view does not reduce the incompatible ideas and experiences of different religions to mere interpretations of the Real and thus preserves their individual dignity. Another response to the diversity and plurality of religious beliefs and deities throughout human history is one of skepticism towards all of them (or even antireligion), seeing them as illusions or human creations which serve human psychological needs. Sigmund Freud was a famous proponent of this view, in various publications such as The Future of an Illusion (1927) and Civilization and Its Discontents (1930). According to Freud, "Religion is an illusion and it derives its strength from the fact that it falls in with our instinctual desires." While one can be skeptical towards the claims of religion, one need not be hostile towards religion. Don Cupitt is one example of someone who, while disbelieving in the metaphysical and cosmological claims of his religion, holds that one can practice it with a "non-realist" perspective which sees religious claims as human inventions and myths to live by. Religious language The question of religious language and in what sense it can be said to be meaningful has been a central issue of the philosophy of religion since the work of the Vienna circle, a group of philosophers who, influenced by Wittgenstein, put forth the theory of Logical positivism. Their view was that religious language, such as any talk of God cannot be verified empirically and thus was ultimately meaningless. This position has also been termed theological noncognitivism. A similar view can be seen in David Hume's An Enquiry Concerning Human Understanding, where he famously wrote that any work which did not include either (1) abstract reasoning on quantity or number or (2) reasoning concerning matter of fact and existence was "nothing but sophistry and illusion". In a similar vein, Antony Flew, questioned the validity of religious statements because they do not seem to be falsifiable, that is, religious claims do not seem to allow any counter evidence to count against them and thus they seem to be lacking in content. While such arguments were popular in the 1950s and 60s, the verification principle and falsifiability as a criterion for meaning are no longer as widely held. The main problem with verificationism is that it seems to be self refuting, for it is a claim which does not seem to be supported by its own criterion. As noted by Brian Davies, when talking about God and religious truths, religious traditions tend to resort to metaphor, negation and analogy. The via negativa has been defended by thinkers such as Maimonides who denied that positive statements about God were helpful and wrote: "you will come nearer to the knowledge and comprehension of God by the negative attributes." Similar approaches based on negation can be seen in the Hindu doctrine of Neti neti and the Buddhist philosophy of Madhyamaka. Wittgenstein's theory of language games also shows how one can use analogical religious language to describe God or religious truths, even if the words one is using do not in this case refer to their everyday sense, i.e. when we say God is wise, we do not mean he is wise in the same sense that a person is wise, yet it can still make sense to talk in this manner. However, as Patrick Sherry notes, the fact that this sort of language may make sense does not mean that one is warranted in ascribing these terms to God, for there must be some connection between the relevant criteria we use in ascribing these terms to conventional objects or subjects and to God. As Chad Meister notes though, for Wittgenstein, a religion's language game need not reflect some literal picture of reality (as a picture theory of meaning would hold) but is useful simply because its ability to "reflect the practices and forms of life of the various religious adherents." Following Wittgenstein, philosophers of religion like Norman Malcolm, B. R. Tilghman, and D. Z. Phillips have argued that instead of seeing religious language as referring to some objective reality, we should instead see it as referring to forms of life. This approach is generally termed non-realist. Against this view, realists respond that non-realism subverts religious belief and the intelligibility of religious practice. It is hard to see for example, how one can pray to a God without believing that they really exist. Realists also argue that non-realism provides no normative way to choose between competing religions. Analytic philosophy of religion In Analytic Philosophy of Religion, | philosophical works included a mixture of religious themes and non-religious philosophical questions. In Asia, examples include texts such as the Hindu Upanishads, the works of Daoism and Confucianism and Buddhist texts. Greek philosophies like Pythagoreanism and Stoicism included religious elements and theories about deities, and Medieval philosophy was strongly influenced by the big three monotheistic Abrahamic religions. In the Western world, early modern philosophers such as Thomas Hobbes, John Locke, and George Berkeley discussed religious topics alongside secular philosophical issues as well. The philosophy of religion has been distinguished from theology by pointing out that, for theology, "its critical reflections are based on religious convictions". Also, "theology is responsible to an authority that initiates its thinking, speaking, and witnessing ... [while] philosophy bases its arguments on the ground of timeless evidence." Some aspects of philosophy of religion have classically been regarded as a part of metaphysics. In Aristotle's Metaphysics, the necessarily prior cause of eternal motion was an unmoved mover, who, like the object of desire, or of thought, inspires motion without itself being moved. Today, however, philosophers have adopted the term "philosophy of religion" for the subject, and typically it is regarded as a separate field of specialization, although it is also still treated by some, particularly Catholic philosophers, as a part of metaphysics. Basic themes and problems Ultimate reality Different religions have different ideas about ultimate reality, its source or ground (or lack thereof) and also about what is the "Maximal Greatness". Paul Tillich's concept of 'Ultimate Concern' and Rudolf Otto's 'Idea of the Holy' are concepts which point to concerns about the ultimate or highest truth which most religious philosophies deal with in some way. One of the main differences among religions is whether the ultimate reality is a personal god or an impersonal reality. In Western religions, various forms of theism are the most common conceptions, while in Eastern religions, there are theistic and also various non-theistic conceptions of the Ultimate. Theistic vs non-theistic is a common way of sorting the different types of religions. There are also several philosophical positions with regard to the existence of God that one might take including various forms of theism (such as monotheism and polytheism), agnosticism and different forms of atheism. Monotheism Keith Yandell outlines roughly three kinds of historical monotheisms: Greek, Semitic and Hindu. Greek monotheism holds that the world has always existed and does not believe in creationism or divine providence, while Semitic monotheism believes the world was created by a God at a particular point in time and that this God acts in the world. Indian monotheism teaches that the world is beginningless, but that there is God's act of creation which sustains the world. The attempt to provide proofs or arguments for the existence of God is one aspect of what is known as natural theology or the natural theistic project. This strand of natural theology attempts to justify belief in God by independent grounds. Perhaps most of the philosophy of religion is predicated on natural theology's assumption that the existence of God can be justified or warranted on rational grounds. There has been considerable philosophical and theological debate about the kinds of proofs, justifications and arguments that are appropriate for this discourse. Non-theistic conceptions Eastern religions have included both theistic and other alternative positions about the ultimate nature of reality. One such view is Jainism, which holds a dualistic view that all that exists is matter and a multiplicity of souls (jiva), without depending on a supreme deity for their existence. There are also different Buddhist views, such as the Theravada Abhidharma view, which holds that the only ultimately existing things are transitory phenomenal events (dharmas) and their interdependent relations. Madhyamaka Buddhists such as Nagarjuna hold that ultimate reality is emptiness (shunyata) while the Yogacara holds that it is vijñapti (mental phenomena). In Indian philosophical discourses, monotheism was defended by Hindu philosophers (particularly the Nyaya school), while Buddhist thinkers argued against their conception of a creator god (Sanskrit: Ishvara). The Hindu view of Advaita Vedanta, as defended by Adi Shankara, is a total non-dualism. Although Advaitins do believe in the usual Hindu gods, their view of ultimate reality is a radically monistic oneness (Brahman without qualities) and anything which appears (like persons and gods) is illusory (maya). The various philosophical positions of Taoism can also be viewed as non-theistic about the ultimate reality (Tao). Taoist philosophers have conceived of different ways of describing the ultimate nature of things. For example, while the Taoist Xuanxue thinker Wang Bi argued that everything is "rooted" in Wu (non-being, nothingness), Guo Xiang rejected Wu as the ultimate source of things, instead arguing that the ultimate nature of the Tao is "spontaneous self-production" (zi sheng) and “spontaneous self-transformation” (zi hua). Traditionally, Jains and Buddhists did not rule out the existence of limited deities or divine beings, they only rejected the idea of a single all-powerful creator God or First cause posited by monotheists. Knowledge and belief All religious traditions make knowledge claims which they argue are central to religious practice and to the ultimate solution to the main problem of human life. These include epistemic, metaphysical and ethical claims. Evidentialism is the position that may be characterized as "a belief is rationally justified only if there is sufficient evidence for it". Many theists and non-theists are evidentialists, for example, Aquinas and Bertrand Russell agree that belief in God is rational only if there is sufficient evidence, but disagree on whether such evidence exists. These arguments often stipulate that subjective religious experiences are not reasonable evidence and thus religious truths must be argued based on non-religious evidence. One of the strongest positions of evidentialism is that by William Kingdon Clifford who wrote: "It is wrong always, everywhere, and for anyone, to believe anything upon insufficient evidence". His view of evidentialism is usually read in tandem with William James's article A Will to Believe (1896), which argues against Clifford's principle. More recent supporters of evidentialism include Antony Flew ("The Presumption of Atheism", 1972) and Michael Scriven (Primary philosophy, 1966). Both of them rely on the Ockhamist view that in the absence of evidence for X, belief in X is not justified. Many modern Thomists are also evidentialists in that they hold they can demonstrate there is evidence for the belief in God. Another move is to argue in a Bayesian way for the probability of a religious truth like God, not for total conclusive evidence. Some philosophers, however, argue that religious belief is warranted without evidence and hence are sometimes called non-evidentialists. They include fideists and reformed epistemologists. Alvin Plantinga and other reformed epistemologists are examples of philosophers who argue that religious beliefs are "properly basic beliefs" and that it is not irrational to hold them even though they are not supported by any evidence. The rationale here is that some beliefs we hold must be foundational and not be based on further rational beliefs. If this is not so we risk an infinite regress. This is qualified by the proviso that they can be defended against objections (this differentiates this view from fideism). A properly basic belief is a belief that one can reasonably hold without evidence, such as a memory, a basic sensation or a perception. Plantinga's argument is that belief in God is of this type because within every human mind there is a natural awareness of divinity. William James in his essay "The Will to Believe" argues for a pragmatic conception of religious belief. For James, religious belief is justified if one is presented with a question which is rationally undecidable and if one is presented with genuine and live options which are relevant for the individual. For James, religious belief is defensible because of the pragmatic value it can bring to one's life, even if there is no rational evidence for it. Some work in recent epistemology of religion goes beyond debates over evidentialism, fideism, and reformed epistemology to consider contemporary issues deriving from new ideas about knowledge-how and practical skill; how practical factors can affect whether one could know whether theism is true; from formal epistemology's use of probability theory; or from social epistemology (particularly the epistemology of testimony, or the epistemology of disagreement). For example, an important topic in the epistemology of religion is that of religious disagreement, and the issue of what it means for intelligent individuals of the same epistemic parity to disagree about religious issues. Religious disagreement has been seen as possibly posing first-order or higher-order problems for religious belief. A first order problem refers to whether that evidence directly applies to the truth of any religious proposition, while a higher order problem instead applies to whether one has rationally assessed the first order evidence. One example of a first order problem is the Argument from nonbelief. Higher order discussions focus on whether religious disagreement with epistemic peers (someone whose epistemic ability is equal to our own) demands us to adopt a skeptical or agnostic stance or whether to reduce or change our religious beliefs. Faith and reason While religions resort to rational arguments to attempt to establish their views, they also claim that religious belief is at least partially to be accepted through faith, confidence or trust in one's religious belief. There are different conceptions or models of faith, including: The affective model of faith sees it as a feeling of trust, a psychological state The special knowledge model of faith as revealing specific religious truths (defended by Reformed epistemology) The belief model of faith as the theoretical conviction that a certain religious claim is true. Faith as trusting, as making a fiducial commitment such as trusting in God. The practical doxastic venture model where faith is seen as a commitment to believe in the trustworthiness of a religious truth or in God. In other words, to trust in God presupposes belief, thus faith must include elements of belief and trust. The non-doxastic venture model of faith as practical commitment without actual belief (defended by non-realists like J. L. Schellenberg and Don Cupitt). In this view, one need not believe in literal religious claims about reality to have religious faith. The hope model, faith as hoping There are also different positions on how faith relates to reason. One example is the belief that faith and reason are compatible and work together, which is the view of Thomas Aquinas and the orthodox view of Catholic natural theology. According to this view, reason establishes certain religious truths and faith (guided by reason) gives us access to truths about the divine which, according to Aquinas, "exceed all the ability of human reason." Another position on is Fideism, the view that faith is "in some sense independent of, if not outright adversarial toward, reason." Modern philosophers such as Kierkegaard, William James, and Wittgenstein have been associated with this label. Kierkegaard in particular, argued for the necessity of the religious to take a non-rational leap of faith to bridge the gulf between man and God. Wittgensteinian fideism meanwhile sees religious language games as being incommensurate with scientific and metaphysical language games, and that they are autonomous and thus may only be judged on their own standards. The obvious criticism to this is that many religions clearly put forth metaphysical claims. Several contemporary New Atheist writers which are hostile to religion hold a related view that says that religious claims and scientific claims are opposed to each other and that therefore religions are false. The Protestant theologian Karl Barth (1886–1968) argued that religious believers have no need to prove their beliefs through reason and thus rejected the project of natural theology. According to Barth, human reason is corrupt and God is utterly different from his creatures, thus we can only rely on God's own revelation for religious knowledge. Barth's view has been termed Neo-orthodoxy. Similarly, D.Z. Phillips argues that God is not intelligible through reason or evidence because God is not an empirical object or a 'being among beings'. As Brian Davies points out, the problem with positions like Barth's is that they do not help us in deciding between inconsistent and competing revelations of the different religions. Science The topic of whether religious beliefs are compatible with science and in what way is also another important topic in the philosophy of religion as well as in theology. This field draws the historical study of their interactions and conflicts, such as the debates in the United States over the teaching of evolution and creationism. There are different models of interaction that have been discussed in the philosophical literature, including : Conflict thesis which sees them as being in constant conflict, such as during the reception of the theory of evolution and the current debate over creationism. Independence model, both have separate domains, or non-overlapping magisteria Dialogue model, some overlap between the fields, they remain separate but share some concepts and presuppositions Integration or unification model includes projects like natural theology and process theology The field also draws the scientific study of religion, particularly by psychologists and sociologists as well as cognitive scientists. Various theories about religion have arisen from these various disciplines. One example is the various evolutionary theories of religion which see the phenomenon as either adaptive or a by-product. Another can be seen in the various theories put forth by the Cognitive science of religion. Some argued that evolutionary or cognitive theories undermine religious belief, Religious experience Closely tied to the issues of knowledge and belief is the question of how to interpret religious experiences vis-à-vis their potential for providing knowledge. Religious experiences have been recorded throughout all cultures and are widely diverse. These personal experiences tend to be highly important to individuals who undergo them. Discussions about religious experiences can be said to be informed in part by the question: "what sort of information about what there is might religious experience provide, and how could one tell?" One could interpret these experiences either veridically, neutrally or as delusions. Both monotheistic and non-monotheistic religious thinkers and mystics have appealed to religious experiences as evidence for their claims about ultimate reality. Philosophers such as Richard Swinburne and William Alston have compared religious experiences to everyday perceptions, that is, both are noetic and have a perceptual object, and thus religious experiences could logically be veridical unless we have a good reason to disbelieve them. According to Brian Davies common objections against the veridical force of religious experiences include the fact that experience is frequently deceptive and that people who claim an experience of a god may be "mistakenly identifying an object of their experience", or be insane or hallucinating. However, he argues that we cannot deduce from the fact that our experiences are sometimes mistaken, hallucinations or distorted to the conclusion that all religious experiences are mistaken etc. Indeed, a drunken or hallucinating person could still perceive things correctly, therefore these objections cannot be said to necessarily disprove all religious experiences. According to C. B. Martin, "there are no tests agreed upon to establish genuine experience of God and distinguish it decisively from the ungenuine", and therefore all that religious experiences can establish is the reality of these psychological states. Naturalistic explanations for religious experiences are often seen as undermining their epistemic value. Explanations such as the fear of death, suggestion, infantile regression, sexual frustration, neurological anomalies ("it's all in the head") as well as the socio-political power that having such experiences might grant to a mystic have been put forward.

court must follow the precedent of the state courts, under the Erie doctrine. If an issue of state law arises during a case in federal court, and there is no decision on point from the highest court of the state, the federal court must either attempt to predict how the state courts would resolve the issue by looking at decisions from state appellate courts, or, if allowed by the constitution of the relevant state, submit the question to the state's courts. On the other hand, when a state court rules on an issue of federal law, the state court is bound only by rulings of the Supreme Court, but not by decisions of federal district or circuit courts of appeals. However some states have adopted a practice of considering themselves bound by rulings of the court of appeals embracing their states, as a matter of comity rather than constitutional obligation. In practice, however, judges in one system will almost always choose to follow relevant case law in the other system to prevent divergent results and to minimize forum shopping. Binding precedent Precedent that must be applied or followed is known as binding precedent (alternately metaphorically precedent, mandatory or binding authority, etc.). Under the doctrine of stare decisis, a lower court must honor findings of law made by a higher court that is within the appeals path of cases the court hears. In state and federal courts in the United States of America, jurisdiction is often divided geographically among local trial courts, several of which fall under the territory of a regional appeals court. All appellate courts fall under a highest court (sometimes but not always called a "supreme court"). By definition, decisions of lower courts are not binding on courts higher in the system, nor are appeals court decisions binding on local courts that fall under a different appeals court. Further, courts must follow their own proclamations of law made earlier on other cases, and honor rulings made by other courts in disputes among the parties before them pertaining to the same pattern of facts or events, unless they have a strong reason to change these rulings (see Law of the case re: a court's previous holding being binding precedent for that court). In law, a binding precedent (also known as a mandatory precedent or binding authority) is a precedent which must be followed by all lower courts under common law legal systems. In English law it is usually created by the decision of a higher court, such as the Supreme Court of the United Kingdom, which took over the judicial functions of the House of Lords in 2009. In civil law and pluralist systems, precedent is not binding but case law is taken into account by the courts. Binding precedent relies on the legal principle of stare decisis. Stare decisis means to stand by things decided. It ensures certainty and consistency in the application of law. Existing binding precedent from past cases are applied in principle to new situations by analogy. One law professor has described mandatory precedent as follows: In extraordinary circumstances a higher court may overturn or overrule mandatory precedent, but will often attempt to distinguish the precedent before overturning it, thereby limiting the scope of the precedent. Under the U.S. legal system, courts are set up in a hierarchy. At the top of the federal or national system is the Supreme Court, and underneath are lower federal courts. The state court systems have hierarchy structures similar to that of the federal system. The U.S. Supreme Court has final authority on questions about the meaning of federal law, including the U.S. Constitution. For example, when the Supreme Court says that the First Amendment applies in a specific way to suits for slander, then every court is bound by that precedent in its interpretation of the First Amendment as it applies to suits for slander. If a lower court judge disagrees with a higher court precedent on what the First Amendment should mean, the lower court judge must rule according to the binding precedent. Until the higher court changes the ruling (or the law itself is changed), the binding precedent is authoritative on the meaning of the law. Lower courts are bound by the precedent set by higher courts within their region. Thus, a federal district court that falls within the geographic boundaries of the Third Circuit Court of Appeals (the mid-level appeals court that hears appeals from district court decisions from Delaware, New Jersey, Pennsylvania, and the Virgin Islands) is bound by rulings of the Third Circuit Court, but not by rulings in the Ninth Circuit (Alaska, Arizona, California, Guam, Hawaii, Idaho, Montana, Nevada, Northern Mariana Islands, Oregon, and Washington), since the Circuit Courts of Appeals have jurisdiction defined by geography. The Circuit Courts of Appeals can interpret the law how they want, so long as there is no binding Supreme Court precedent. One of the common reasons the Supreme Court grants certiorari (that is, they agree to hear a case) is if there is a conflict among the circuit courts as to the meaning of a federal law. There are three elements needed for a precedent to work. Firstly, the hierarchy of the courts needs to be accepted, and an efficient system of law reporting. "A balance must be struck between the need on one side for the legal certainty resulting from the binding effect of previous decisions, and on the other side the avoidance of undue restriction on the proper development of the law" (1966 Practice Statement (Judicial Precedent) by Lord Gardiner L.C.). Binding precedent in English law Judges are bound by the law of binding precedent in England and Wales and other common law jurisdictions. This is a distinctive feature of the English legal system. In Scotland and many countries throughout the world, particularly in mainland Europe, civil law means that judges take case law into account in a similar way, but are not obliged to do so and are required to consider the precedent in terms of principle. Their fellow judges' decisions may be persuasive but are not binding. Under the English legal system, judges are not necessarily entitled to make their own decisions about the development or interpretations of the law. They may be bound by a decision reached in a previous case. Two facts are crucial to determining whether a precedent is binding: The position in the court hierarchy of the court which decided the precedent, relative to the position in the court trying the current case. Whether the facts of the current case come within the scope of the principle of law in previous decisions. In a conflict of laws situation, jus cogens norms erga omnes and principles of the common law such as in the Universal Declaration of Human Rights, to a varying degree in different jurisdictions, are deemed overriding which means they are used to "read down" legislation, that is giving them a particular purposive interpretation, for example applying European Court of Human Rights jurisprudence of courts (case law). "Super stare decisis" "Super stare decisis" is a term used for important precedent that is resistant or immune from being overturned, without regard to whether correctly decided in the first place. It may be viewed as one extreme in a range of precedential power, or alternatively, to express a belief, or a critique of that belief, that some decisions should not be overturned. In 1976, Richard Posner and William Landes coined the term "super-precedent" in an article they wrote about testing theories of precedent by counting citations. Posner and Landes used this term to describe the influential effect of a cited decision. The term "super-precedent" later became associated with different issue: the difficulty of overturning a decision. In 1992, Rutgers professor Earl Maltz criticized the Supreme Court's decision in Planned Parenthood v. Casey for endorsing the idea that if one side can take control of the Court on an issue of major national importance (as in Roe v. Wade), that side can protect its position from being reversed "by a kind of super-stare decisis". The controversial idea that some decisions are virtually immune from being overturned, regardless of whether they were decided correctly in the first place, is the idea to which the term "super-stare decisis" now usually refers. The concept of super-stare decisis (or "super-precedent") was mentioned during the hearings of Chief Justice John Roberts and Justice Samuel Alito before the Senate Judiciary Committee. Prior to the commencement of the Roberts hearings, the committee chair, Senator Arlen Specter of Pennsylvania, wrote an op-ed in The New York Times referring to Roe as a "super-precedent". He revisited this concept during the hearings, but neither Roberts nor Alito endorsed the term or the concept. Persuasive precedent Persuasive precedent (also persuasive authority) is precedent or other legal writing that is not binding precedent but that is useful or relevant and that may guide the judge in making the decision in a current case. Persuasive precedent includes cases decided by lower courts, by peer or higher courts from other geographic jurisdictions, cases made in other parallel systems (for example, military courts, administrative courts, indigenous/tribal courts, state courts versus federal courts in the United States), statements made in dicta, treatises or academic law reviews, and in some exceptional circumstances, cases of other nations, treaties, world judicial bodies, etc. In a "case of first impression", courts often rely on persuasive precedent from courts in other jurisdictions that have previously dealt with similar issues. Persuasive precedent may become binding through its adoption by a higher court. In civil law and pluralist systems, as under Scots law, precedent is not binding but case law is taken into account by the courts. Higher courts in other circuits A court may consider the ruling of a higher court that is not binding. For example, a district court in the United States First Circuit could consider a ruling made by the United States Court of Appeals for the Ninth Circuit as persuasive authority. Horizontal courts Courts may consider rulings made in other courts that are of equivalent authority in the legal system. For example, an appellate court for one district could consider a ruling issued by an appeals court in another district. Statements made in obiter dicta Courts may consider obiter dicta in opinions of higher courts. Dicta of a higher court, though not binding, will often be persuasive to lower courts. The phrase obiter dicta is usually translated as "other things said", but due to the high number of judges and individual concurring opinions, it is often hard to distinguish from the ratio decidendi (reason for the decision). For these reasons, the obiter dicta may often be taken into consideration by a court. A litigant may also consider obiter dicta if a court has previously signaled that a particular legal argument is weak and may even warrant sanctions if repeated. Dissenting opinions A case decided by a multijudge panel could result in a split decision. While only the majority opinion is considered precedential, an outvoted judge can still publish a dissenting opinion. Common patterns for dissenting opinions include: an explanation of how the outcome of the case might be different on slightly different facts, in an attempt to limit the holding of the majority planting seeds for a future overruling of the majority opinion A judge in a subsequent case, particularly in a different jurisdiction, could find the dissenting judge's reasoning persuasive. In the jurisdiction of the original decision, however, a judge should only overturn the holding of a court lower or equivalent in the hierarchy. A district court, for example, could not rely on a Supreme Court dissent as a basis to depart from the reasoning of the majority opinion. However, lower courts occasionally cite dissents, either for a limiting principle on the majority, or for propositions that are not stated in the majority opinion and not inconsistent with that majority, or to explain a disagreement with the majority and to urge reform (while following the majority in the outcome). Treatises, restatements, law review articles Courts may consider the writings of eminent legal scholars in treatises, restatements of the law, and law reviews. The extent to which judges find these types of writings persuasive will vary widely with elements such as the reputation of the author and the relevance of the argument. Persuasive effect of decisions from other jurisdictions The courts of England and Wales are free to consider decisions of other jurisdictions, and give them whatever persuasive weight the English court sees fit, even though these other decisions are not binding precedent. Jurisdictions that are closer to modern English common law are more likely to be given persuasive weight (for example Commonwealth states such as Canada, Australia, or New Zealand). Persuasive weight might be given to other common law courts, such as from the United States, most often where the American courts have been particularly innovative, e.g. in product liability and certain areas of contract law. In the United States, in the late 20th and early 21st centuries, the concept of a U.S. court considering foreign law or precedent has been considered controversial by some parties. The Supreme Court splits on this issue. This critique is recent, as in the early history of the United States, citation of English authority was ubiquitous. One of the first acts of many of the new state legislatures was to adopt the body of English common law into the law of the state. Citation to English cases was common through the 19th and well into the 20th centuries. Even in the late 20th and early 21st centuries, it is relatively uncontroversial for American state courts to rely on English decisions for matters of pure common (i.e. judge-made) law. Within the federal legal systems of several common-law countries, and most especially the United States, it is relatively common for the distinct lower-level judicial systems (e.g. state courts in the United States and Australia, provincial courts in Canada) to regard the decisions of other jurisdictions within the same country as persuasive precedent. Particularly in the United States, the adoption of a legal doctrine by a large number of other state judiciaries is regarded as highly persuasive evidence that such doctrine is preferred. A good example is the adoption in Tennessee of comparative negligence (replacing contributory negligence as a complete bar to recovery) by the 1992 Tennessee Supreme Court decision McIntyre v. Balentine (by this point all US jurisdictions save Tennessee, five other states, and the District of Columbia had adopted comparative negligence schemes). Moreover, in American law, the Erie doctrine requires federal courts sitting in diversity actions to apply state substantive law, but in a manner consistent with how the court believes the state's highest court would rule in that case. Since such decisions are not binding on state courts, but are often very well-reasoned and useful, state courts cite federal interpretations of state law fairly often as persuasive precedent, although it is also fairly common for a state high court to reject a federal court's interpretation of its jurisprudence. Nonprecedential decisions: unpublished decisions, non-publication and depublication, noncitation rules Nonpublication of opinions, or unpublished opinions, are those decisions of courts that are not available for citation as precedent because the judges making the opinion deem the cases as having less precedential value. Selective publication is the legal process which a judge or justices of a court decide whether a decision is to be or not published in a reporter. "Unpublished" federal appellate decisions are published in the Federal Appendix. Depublication is the power of a court to make a previously published order or opinion unpublished. Litigation that is settled out of court generates no written decision, thus has no precedential effect. As one practical effect, the U.S. Department of Justice settles many cases against the federal government simply to avoid creating adverse precedent. Res judicata, claim preclusion, collateral estoppel, issue preclusion, law of the case Several rules may cause a decision to apply as narrow "precedent" to preclude future legal positions of the specific parties to a case, even if a decision is non-precedential with respect to all other parties. Res judicata, claim preclusion Once a case is decided, the same plaintiff cannot sue the same defendant again on any claim arising out of the same facts. The law requires plaintiffs to put all issues on the table in a single case, not split the case. For example, in a case of an auto accident, the plaintiff cannot sue first for property damage, and then personal injury in a separate case. This is called res judicata or claim preclusion ("Res judicata" is the traditional name | subsequent cases found the principles underpinning the previous decision erroneous in law or overtaken by new legislation or developments. In contrast, civil law systems adhere to a legal positivism, where past decisions do not usually have the precedential, binding effect that they have in common law decision-making; the judicial review practiced by constitutional courts can be regarded as a notable exception. Principle Stare decisis () is a legal principle by which judges are obligated to respect the precedent established by prior decisions. The words originate from the phrasing of the principle in the Latin maxim Stare decisis et non quieta movere: "to stand by decisions and not disturb the undisturbed". In a legal context, this means that courts should abide by precedent and not disturb settled matters. The principle can be divided into two components: A decision made by a superior court, or by the same court in an earlier decision, is binding precedent that the court itself and all its inferior courts must follow. A court may overturn its own precedent, but should do so only if a strong reason exists to do so, and even in that case, should be guided by principles from superior, lateral, and inferior courts. The second principle, regarding persuasive precedent, reflects the broad precedent guidance a court may draw upon in reaching all of its decisions. Case law in common-law systems In the common-law tradition, courts decide the law applicable to a case by interpreting statutes and applying precedent, which record how and why prior cases have been decided. Unlike most civil-law systems, common-law systems follow the doctrine of stare decisis, by which most courts are bound by their own previous decisions in similar cases, and all lower courts should make decisions consistent with previous decisions of higher courts. For example, in England, the High Court and the Court of Appeal are each bound by their own previous decisions, but the Supreme Court of the United Kingdom is able to deviate from its earlier decisions, although in practice it rarely does so. Generally speaking, higher courts do not have direct oversight over day-to-day proceedings in lower courts, in that they cannot reach out on their own initiative (sua sponte) at any time to reverse or overrule decisions of the lower courts. Normally, the burden rests with litigants to appeal rulings (including those in clear violation of established case law) to the higher courts. If a judge acts against precedent and the case is not appealed, the decision will stand. A lower court may not rule against a binding precedent, even if the lower court feels that the precedent is unjust; the lower court may only express the hope that a higher court or the legislature will reform the rule in question. If the court believes that developments or trends in legal reasoning render the precedent unhelpful, and wishes to evade it and help the law evolve, the court may either hold that the precedent is inconsistent with subsequent authority, or that the precedent should be "distinguished: by some material difference between the facts of the cases. If that decision goes to appeal, the appellate court will have the opportunity to review both the precedent and the case under appeal, perhaps overruling the previous case law by setting a new precedent of higher authority. This may happen several times as the case works its way through successive appeals. Lord Denning, first of the High Court of Justice, later of the Court of Appeal, provided a famous example of this evolutionary process in his development of the concept of estoppel starting in the High Trees case: Central London Property Trust Ltd v. High Trees House Ltd [1947] K.B. 130. Judges may refer to various types of persuasive authority to reach a decision in a case. Widely cited nonbinding sources include legal encyclopedias such as Corpus Juris Secundum and Halsbury's Laws of England, or the published work of the Law Commission or the American Law Institute. Some bodies are given statutory powers to issue guidance with persuasive authority or similar statutory effect, such as the Highway Code. In federal or multijurisdictional law systems, conflicts may exist between the various lower appellate courts. Sometimes these differences may not be resolved and distinguishing how the law is applied in one district, province, division or appellate department may be necessary. Usually, only an appeal accepted by the court of last resort will resolve such differences, and for many reasons, such appeals are often not granted. Any court may seek to distinguish its present case from that of a binding precedent, to reach a different conclusion. The validity of such a distinction may or may not be accepted on appeal. An appellate court may also propound an entirely new and different analysis from that of junior courts, and may or may not be bound by its own previous decisions, or in any case may distinguish the decisions based on significant differences in the facts applicable to each case. Or, a court may view the matter before it as one of "first impression", not governed by any controlling precedent. When various members of a multi-judge court write separate opinions, the reasoning may differ; only the ratio decidendi of the majority becomes binding precedent. For example, if a 12-member court splits 5–2–3–2 in four different opinions on several different issues, whatever reasoning commands seven votes on each specific issue becomes precedent, and the seven-judge majorities may differ issue-to-issue. All may be cited as persuasive (though of course opinions that concur in the majority result are more persuasive than dissents). Quite apart from the rules of precedent, the weight actually given to any reported opinion may depend on the reputation of both the court and the judges with respect to the specific issue. For example, in the United States, the Second Circuit (New York and surrounding states) is especially respected in commercial and securities law, the Seventh Circuit (in Chicago), especially Judge Posner, is highly regarded on antitrust, and the District of Columbia Circuit is highly regarded on administrative law. Categories and classifications of precedent, and effect of classification Verticality Generally, a common law court system has trial courts, intermediate appellate courts and a supreme court. The inferior courts conduct almost all trial proceedings. The inferior courts are bound to obey precedent established by the appellate court for their jurisdiction, and all supreme court precedent. The Supreme Court of California's explanation of this principle is that An Intermediate state appellate court is generally bound to follow the decisions of the highest court of that state. The application of the doctrine of stare decisis from a superior court to an inferior court is sometimes called vertical stare decisis. Horizontality The idea that a judge is bound by (or at least should respect) decisions of earlier judges of similar or coordinate level is called horizontal stare decisis. In the United States federal court system, the intermediate appellate courts are divided into thirteen "circuits", each covering some range of territory ranging in size from the District of Columbia alone, and up to seven states. Each panel of judges on the court of appeals for a circuit is bound to obey the prior appellate decisions of the same circuit. Precedent of a United States court of appeals may be overruled only by the court en banc, that is, a session of all the active appellate judges of the circuit, or by the United States Supreme Court, not simply by a different three-judge panel. When a court binds itself, this application of the doctrine of precedent is sometimes called horizontal stare decisis. The state of New York has a similar appellate structure as it is divided into four appellate departments supervised by the final New York Court of Appeals. Decisions of one appellate department are not binding upon another, and in some cases the departments differ considerably on interpretations of law. Federalism and parallel state and federal courts In federal systems the division between federal and state law may result in complex interactions. In the United States, state courts are not considered inferior to federal courts but rather constitute a parallel court system. When a federal court rules on an issue of state law, the federal court must follow the precedent of the state courts, under the Erie doctrine. If an issue of state law arises during a case in federal court, and there is no decision on point from the highest court of the state, the federal court must either attempt to predict how the state courts would resolve the issue by looking at decisions from state appellate courts, or, if allowed by the constitution of the relevant state, submit the question to the state's courts. On the other hand, when a state court rules on an issue of federal law, the state court is bound only by rulings of the Supreme Court, but not by decisions of federal district or circuit courts of appeals. However some states have adopted a practice of considering themselves bound by rulings of the court of appeals embracing their states, as a matter of comity rather than constitutional obligation. In practice, however, judges in one system will almost always choose to follow relevant case law in the other system to prevent divergent results and to minimize forum shopping. Binding precedent Precedent that must be applied or followed is known as binding precedent (alternately metaphorically precedent, mandatory or binding authority, etc.).

In state and federal courts in the United States of America, jurisdiction is often divided geographically among local trial courts, several of which fall under the territory of a regional appeals court. All appellate courts fall under a highest court (sometimes but not always called a "supreme court"). By definition, decisions of lower courts are not binding on courts higher in the system, nor are appeals court decisions binding on local courts that fall under a different appeals court. Further, courts must follow their own proclamations of law made earlier on other cases, and honor rulings made by other courts in disputes among the parties before them pertaining to the same pattern of facts or events, unless they have a strong reason to change these rulings (see Law of the case re: a court's previous holding being binding precedent for that court). In law, a binding precedent (also known as a mandatory precedent or binding authority) is a precedent which must be followed by all lower courts under common law legal systems.

Under the U.S. legal system, courts are set up in a hierarchy. At the top of the federal or national system is the Supreme Court, and underneath are lower federal courts.

Until the higher court changes the ruling (or the law itself is changed), the binding precedent is authoritative on the meaning of the law. Lower courts are bound by the precedent set by higher courts within their region. Thus, a federal district court that falls within the geographic boundaries of the Third Circuit Court of Appeals (the mid-level appeals court that hears appeals from district court decisions from Delaware, New Jersey, Pennsylvania, and the Virgin Islands) is bound by rulings of the Third Circuit Court, but not by rulings in the Ninth Circuit (Alaska, Arizona, California, Guam, Hawaii, Idaho, Montana, Nevada, Northern Mariana Islands, Oregon, and Washington), since the Circuit Courts of Appeals have jurisdiction defined by geography. The Circuit Courts of Appeals can interpret the law how they want, so long as there is no binding Supreme Court precedent.

Under the English legal system, judges are not necessarily entitled to make their own decisions about the development or interpretations of the law. They may be bound by a decision reached in a previous case. Two facts are crucial to determining whether a precedent is binding: The position in the court hierarchy of the court which decided the precedent, relative to the position in the court trying the current case. Whether the facts of the current case come within the scope of the principle of law in previous decisions. In a conflict of laws situation, jus cogens norms erga omnes and principles of the common law such as in the Universal Declaration of Human Rights, to a varying degree in different jurisdictions, are deemed overriding which means they are used to "read down" legislation, that is giving them a particular purposive interpretation, for example applying European Court of Human Rights jurisprudence of courts (case law).

with Dick during his X-Kalay stint), he donated manuscripts, papers and other materials to the university's Special Collections Library, where they are in the Philip K. Dick Science Fiction Collection in the Pollak Library. During this period, Dick befriended a circle of Fullerton State students that included several aspiring science fiction writers, including K. W. Jeter, James Blaylock and Tim Powers. Jeter would later continue Dick's Bladerunner series with three sequels. Dick returned to the events of these months while writing his novel A Scanner Darkly (1977), which contains fictionalized depictions of the burglary of his home, his time using amphetamines and living with addicts, and his experiences of X-Kalay (portrayed in the novel as "New-Path"). A factual account of his recovery program participation was portrayed in his posthumously released book The Dark Haired Girl, a collection of letters and journals from the period. Paranormal experiences On February 20, 1974, while recovering from the effects of sodium pentothal administered for the extraction of an impacted wisdom tooth, Dick received a home delivery of Darvon from a young woman. When he opened the door, he was struck by the dark-haired girl's beauty, and was especially drawn to her golden necklace. He asked her about its curious fish-shaped design. As she was leaving, she replied: "This is a sign used by the early Christians." Dick called the symbol the "vesicle pisces". This name seems to have been based on his conflation of two related symbols, the Christian ichthys symbol (two intersecting arcs delineating a fish in profile), which the woman was wearing, and the vesica piscis. Dick recounted that as the sun glinted off the gold pendant, the reflection caused the generation of a "pink beam" of light that mesmerized him. He came to believe the beam imparted wisdom and clairvoyance, and also believed it to be intelligent. On one occasion, he was startled by a separate recurrence of the pink beam, which imparted the information that his infant son was ill. The Dicks rushed the child to the hospital, where the illness was confirmed by professional diagnosis. After the woman's departure, Dick began experiencing strange hallucinations. Although initially attributing them to side effects from medication, he considered this explanation implausible after weeks of continued hallucination. He told Charles Platt: "I experienced an invasion of my mind by a transcendentally rational mind, as if I had been insane all my life and suddenly I had become sane." Throughout February and March 1974, Dick experienced a series of hallucinations which he referred to as "2-3-74", shorthand for February–March 1974. Aside from the "pink beam", he described the initial hallucinations as geometric patterns, and, occasionally, brief pictures of Jesus and ancient Rome. As the hallucinations increased in duration and frequency, Dick claimed he began to live two parallel lives—one as himself, "Philip K. Dick", and one as "Thomas", a Christian persecuted by Romans in the first century AD. He referred to the "transcendentally rational mind" as "Zebra", "God" and "VALIS" (an acronym for Vast Active Living Intelligence System). He wrote about the experiences, first in the semi-autobiographical novel Radio Free Albemuth, then in VALIS, The Divine Invasion, The Transmigration of Timothy Archer and the unfinished The Owl in Daylight (the VALIS trilogy). In 1974, Dick wrote a letter to the FBI, accusing various people, including University of California, San Diego professor Fredric Jameson, of being foreign agents of Warsaw Pact powers. He also wrote that Stanisław Lem was probably a false name used by a composite committee operating on orders of the Communist party to gain control over public opinion. At one point, Dick felt he had been taken over by the spirit of the prophet Elijah. He believed that an episode in his novel Flow My Tears, the Policeman Said was a detailed retelling of a biblical story from the Book of Acts, which he had never read. He documented and discussed his experiences and faith in a private journal he called his "exegesis", portions of which were later published as The Exegesis of Philip K. Dick. The last novel he wrote was The Transmigration of Timothy Archer; it was published shortly after his death in 1982. Personal life Dick was married five times: Jeanette Marlin (May to November 1948) Kleo Apostolides (June 14, 1950 to 1959) Anne Williams Rubinstein (April 1, 1959 to October 1965) Nancy Hackett (July 6, 1966 to 1972) Leslie "Tessa" Busby (April 18, 1973 to 1977) Dick had three children, Laura Archer Dick (born February 25, 1960, to Dick and his third wife, Anne Williams Rubenstein), Isolde Freya Dick (now Isa Dick Hackett) (born March 15, 1967, to Dick and his fourth wife, Nancy Hackett), and Christopher Kenneth Dick (born July 25, 1973, to Dick and his fifth wife, Leslie "Tessa" Busby). In 1955, Dick and his second wife, Kleo Apostolides, received a visit from the FBI, which they believed to be the result of Kleo's socialist views and left-wing activities. The couple briefly befriended one of the FBI agents. He was physically abusive with his third wife, Anne Williams Rubinstein; after one argument in 1963, he attempted to push her off a cliff in a car, then later claimed she was trying to kill him, and persuaded a psychiatrist to commit her involuntarily. After filing for divorce in 1964, he moved to Oakland to live with a fan, author and editor Grania Davis. Shortly after, he attempted suicide by driving off the road while she was a passenger. Dick tried to stay out of the political scene because of high societal turmoil from the Vietnam War. Still, he did show some anti-Vietnam War and anti-governmental sentiments. In 1968, he joined the "Writers and Editors War Tax Protest", an anti-war pledge to pay no U.S. federal income tax, which resulted in the confiscation of his car by the IRS. Death On February 17, 1982, after completing an interview, Dick contacted his therapist, complaining of failing eyesight, and was advised to go to a hospital immediately, but did not. The following day, he was found unconscious on the floor of his Santa Ana, California home, having suffered a stroke. On February 25, 1982, Dick suffered another stroke in the hospital, which led to brain death. Five days later, on March 2, 1982, he was disconnected from life support. After his death, Dick's father, Joseph, took his son's ashes to Riverside Cemetery in Fort Morgan, Colorado, (section K, block 1, lot 56), where they were buried next to his twin sister Jane, who died in infancy. Her tombstone had been inscribed with both of their names at the time of her death, 53 years earlier. Philip died four months before the release of Blade Runner, the film based on his novel Do Androids Dream of Electric Sheep?. Style and works Themes Dick's stories typically focus on the fragile nature of what is real and the construction of personal identity. His stories often become surreal fantasies, as the main characters slowly discover that their everyday world is actually an illusion assembled by powerful external entities, such as the suspended animation in Ubik, vast political conspiracies or the vicissitudes of an unreliable narrator. "All of his work starts with the basic assumption that there cannot be one, single, objective reality", writes science fiction author Charles Platt. "Everything is a matter of perception. The ground is liable to shift under your feet. A protagonist may find himself living out another person's dream, or he may enter a drug-induced state that actually makes better sense than the real world, or he may cross into a different universe completely." Alternate universes and simulacra are common plot devices, with fictional worlds inhabited by common, working people, rather than galactic elites. "There are no heroes in Dick's books", Ursula K. Le Guin wrote, "but there are heroics. One is reminded of Dickens: what counts is the honesty, constancy, kindness and patience of ordinary people." Dick made no secret that much of his thinking and work was heavily influenced by the writings of Carl Jung. The Jungian constructs and models that most concerned Dick seem to be the archetypes of the collective unconscious, group projection/hallucination, synchronicities, and personality theory. Many of Dick's protagonists overtly analyze reality and their perceptions in Jungian terms (see Lies, Inc.). Dick identified one major theme of his work as the question, "What constitutes the authentic human being?" In works such as Do Androids Dream of Electric Sheep?, beings can appear totally human in every respect while lacking soul or compassion, while completely alien beings such as Glimmung in Galactic Pot-Healer may be more humane and complex than their human peers. Mental illness was a constant interest of Dick's, and themes of mental illness permeate his work. The character Jack Bohlen in the 1964 novel Martian Time-Slip is an "ex-schizophrenic". The novel Clans of the Alphane Moon centers on an entire society made up of descendants of lunatic asylum inmates. In 1965, he wrote the essay titled "Schizophrenia and the Book of Changes". Drug use (including religious, recreational, and abuse) was also a theme in many of Dick's works, such as A Scanner Darkly and The Three Stigmata of Palmer Eldritch. Dick himself was a drug user for much of his life. According to a 1975 interview in Rolling Stone, Dick wrote all of his books published before 1970 while on amphetamines. "A Scanner Darkly (1977) was the first complete novel I had written without speed", said Dick in the interview. He also experimented briefly with psychedelics, but wrote The Three Stigmata of Palmer Eldritch (1965), which Rolling Stone dubs "the classic LSD novel of all time", before he had ever tried them. Despite his heavy amphetamine use, however, Dick later said that doctors told him the amphetamines never actually affected him, that his liver had processed them before they reached his brain. Summing up all these themes in Understanding Philip K. Dick, Eric Carl Link discussed eight themes or 'ideas and motifs': Epistemology and the Nature of Reality, Know Thyself, The Android and the Human, Entropy and Pot Healing, The Theodicy Problem, Warfare and Power Politics, The Evolved Human, and 'Technology, Media, Drugs and Madness'. Pen names Dick had two professional stories published under the pen names Richard Phillipps and Jack Dowland. "Some Kinds of Life" was published in October 1953 in Fantastic Universe under byline Richard Phillipps, apparently because the magazine had a policy against publishing multiple stories by the same author in the same issue; "Planet for Transients" was published in the same issue under his own name. The short story "Orpheus with Clay Feet" was published under the pen name Jack Dowland. The protagonist desires to be the muse for fictional author Jack Dowland, considered the greatest science fiction author of the 20th century. In the story, Dowland publishes a short story titled "Orpheus with Clay Feet" under the pen name Philip K. Dick. The surname Dowland refers to Renaissance composer John Dowland, who is featured in several works. The title Flow My Tears, the Policeman Said directly refers to Dowland's best-known composition, "Flow, my tears". In the novel The Divine Invasion, the character Linda Fox, created specifically with Linda Ronstadt in mind, is an intergalactically famous singer whose entire body of work consists of recordings of John Dowland compositions. Selected works The Man in the High Castle (1962) is set in an alternate history in which the United States is ruled by the victorious Axis powers. It is the only Dick novel to win a Hugo Award. In 2015 this was adapted into a television series by Amazon Studios. The Three Stigmata of Palmer Eldritch (1965) utilizes an array of science fiction concepts and features several layers of reality and unreality. It is also one of Dick's first works to explore religious themes. The novel takes place in the 21st century, when, under UN authority, mankind has colonized the Solar System's every habitable planet and moon. Life is physically daunting and psychologically monotonous for most colonists, so the UN must draft people to go to the colonies. Most entertain themselves using "Perky Pat" dolls and accessories manufactured by Earth-based "P.P. Layouts". The company also secretly creates "Can-D", an illegal but widely available hallucinogenic drug allowing the user to "translate" into Perky Pat (if the drug user is a woman) or Pat's boyfriend, Walt (if the drug user is a man). This recreational use of Can-D allows colonists to experience a few minutes of an idealized life on Earth by participating in a collective hallucination. Do Androids Dream of Electric Sheep? (1968) is the story of a bounty hunter policing the local android population. It occurs on a dying, poisoned Earth de-populated of almost all animals and all "successful" humans; the only remaining inhabitants of the planet are people with no prospects off-world. The 1968 novel is the literary source of the film Blade Runner (1982). It is both a conflation and an intensification of the pivotally Dickian question: "What is real, what is fake? What crucial factor defines humanity as distinctly 'alive', versus those merely alive only in their outward appearance?" Ubik (1969) employs extensive psychic telepathy and a suspended state after death in creating a state of eroding reality. A group of psychics is sent to investigate a rival organisation, but several of them are apparently killed by a saboteur's bomb. Much of the following novel flicks between different equally plausible realities and the "real" reality, a state of half-life and psychically manipulated realities. In 2005, Time magazine listed it among the "All-TIME 100 Greatest Novels" published since 1923. Flow My Tears, the Policeman Said (1974) concerns Jason Taverner, a television star living in a dystopian near-future police state. After being attacked by an angry ex-girlfriend, Taverner awakens in a dingy Los Angeles hotel room. He still has his money in his wallet, but his identification cards are missing. This is no minor inconvenience, as security checkpoints (staffed by "pols" and "nats", the police and National Guard) are set up throughout the city to stop and arrest anyone without valid ID. Jason at first thinks that he was robbed, but soon discovers that his entire identity has been erased. There is no record of him in any official database, and even his closest associates do not recognize or remember him. For the first time in many years, Jason has no fame or reputation to rely on. He has only his innate charm and social graces to help him as he tries to find out what happened to his past while avoiding the attention of the pols. The novel was Dick's first published novel after years of silence, during which time his critical reputation had grown, and this novel was awarded the John W. Campbell Memorial Award for Best Science Fiction Novel. It is the only Philip K. Dick novel nominated for both a Hugo and a Nebula Award. In an essay written two years before his death, Dick described how he learned from his Episcopal priest that an important scene in Flow My Tears, the Policeman Said – involving its other main character, the eponymous Police General Felix Buckman, was very similar to a scene in Acts of the Apostles, a book of the New Testament. Film director Richard Linklater discusses this novel in his film Waking Life, which begins with a scene reminiscent of another Dick novel, Time Out of Joint. A Scanner Darkly (1977) is a bleak mixture of science fiction and police procedural novels; in its story, an undercover narcotics police detective begins to lose touch with reality after falling victim to Substance D, the same permanently mind-altering drug he was enlisted to help fight. Substance D is instantly addictive, beginning with a pleasant euphoria which is quickly replaced with increasing confusion, hallucinations and eventually total psychosis. In this novel, as with all Dick novels, there is an underlying thread of paranoia and dissociation with multiple realities perceived simultaneously. It was adapted to film by Richard Linklater. The Philip K. Dick Reader is an introduction to the variety of Dick's short fiction. VALIS (1980) is perhaps Dick's most postmodern and autobiographical novel, examining his own unexplained experiences. It may also be his most academically studied work, and was adapted as an opera by Tod Machover. Later works like the VALIS trilogy were heavily autobiographical, many with "two-three-seventy-four" (2-3-74) references and influences. The word VALIS is the acronym for Vast Active Living Intelligence System. Later, Dick theorized that VALIS was both a "reality generator" and a means of extraterrestrial communication. A fourth VALIS manuscript, Radio Free Albemuth, although composed in 1976, was posthumously published in 1985. This work is described by the publisher (Arbor House) as "an introduction and key to his magnificent VALIS trilogy". Regardless of the feeling that he was somehow experiencing a divine communication, Dick was never fully able to rationalize the events. For the rest of his life, he struggled to comprehend what was occurring, questioning his own sanity and perception of reality. He transcribed what thoughts he could into an eight-thousand-page, one-million-word journal dubbed the Exegesis. From 1974 until his death in 1982, Dick spent many nights writing in this journal. | On March 23, 1972, Dick attempted suicide by taking an overdose of the sedative potassium bromide. Subsequently, after deciding to seek help, Dick became a participant in X-Kalay (a Canadian Synanon-type recovery program), and was well enough by April to return to California. On relocating to Orange County, California at the behest of California State University, Fullerton professor Willis McNelly (who initiated a correspondence with Dick during his X-Kalay stint), he donated manuscripts, papers and other materials to the university's Special Collections Library, where they are in the Philip K. Dick Science Fiction Collection in the Pollak Library. During this period, Dick befriended a circle of Fullerton State students that included several aspiring science fiction writers, including K. W. Jeter, James Blaylock and Tim Powers. Jeter would later continue Dick's Bladerunner series with three sequels. Dick returned to the events of these months while writing his novel A Scanner Darkly (1977), which contains fictionalized depictions of the burglary of his home, his time using amphetamines and living with addicts, and his experiences of X-Kalay (portrayed in the novel as "New-Path"). A factual account of his recovery program participation was portrayed in his posthumously released book The Dark Haired Girl, a collection of letters and journals from the period. Paranormal experiences On February 20, 1974, while recovering from the effects of sodium pentothal administered for the extraction of an impacted wisdom tooth, Dick received a home delivery of Darvon from a young woman. When he opened the door, he was struck by the dark-haired girl's beauty, and was especially drawn to her golden necklace. He asked her about its curious fish-shaped design. As she was leaving, she replied: "This is a sign used by the early Christians." Dick called the symbol the "vesicle pisces". This name seems to have been based on his conflation of two related symbols, the Christian ichthys symbol (two intersecting arcs delineating a fish in profile), which the woman was wearing, and the vesica piscis. Dick recounted that as the sun glinted off the gold pendant, the reflection caused the generation of a "pink beam" of light that mesmerized him. He came to believe the beam imparted wisdom and clairvoyance, and also believed it to be intelligent. On one occasion, he was startled by a separate recurrence of the pink beam, which imparted the information that his infant son was ill. The Dicks rushed the child to the hospital, where the illness was confirmed by professional diagnosis. After the woman's departure, Dick began experiencing strange hallucinations. Although initially attributing them to side effects from medication, he considered this explanation implausible after weeks of continued hallucination. He told Charles Platt: "I experienced an invasion of my mind by a transcendentally rational mind, as if I had been insane all my life and suddenly I had become sane." Throughout February and March 1974, Dick experienced a series of hallucinations which he referred to as "2-3-74", shorthand for February–March 1974. Aside from the "pink beam", he described the initial hallucinations as geometric patterns, and, occasionally, brief pictures of Jesus and ancient Rome. As the hallucinations increased in duration and frequency, Dick claimed he began to live two parallel lives—one as himself, "Philip K. Dick", and one as "Thomas", a Christian persecuted by Romans in the first century AD. He referred to the "transcendentally rational mind" as "Zebra", "God" and "VALIS" (an acronym for Vast Active Living Intelligence System). He wrote about the experiences, first in the semi-autobiographical novel Radio Free Albemuth, then in VALIS, The Divine Invasion, The Transmigration of Timothy Archer and the unfinished The Owl in Daylight (the VALIS trilogy). In 1974, Dick wrote a letter to the FBI, accusing various people, including University of California, San Diego professor Fredric Jameson, of being foreign agents of Warsaw Pact powers. He also wrote that Stanisław Lem was probably a false name used by a composite committee operating on orders of the Communist party to gain control over public opinion. At one point, Dick felt he had been taken over by the spirit of the prophet Elijah. He believed that an episode in his novel Flow My Tears, the Policeman Said was a detailed retelling of a biblical story from the Book of Acts, which he had never read. He documented and discussed his experiences and faith in a private journal he called his "exegesis", portions of which were later published as The Exegesis of Philip K. Dick. The last novel he wrote was The Transmigration of Timothy Archer; it was published shortly after his death in 1982. Personal life Dick was married five times: Jeanette Marlin (May to November 1948) Kleo Apostolides (June 14, 1950 to 1959) Anne Williams Rubinstein (April 1, 1959 to October 1965) Nancy Hackett (July 6, 1966 to 1972) Leslie "Tessa" Busby (April 18, 1973 to 1977) Dick had three children, Laura Archer Dick (born February 25, 1960, to Dick and his third wife, Anne Williams Rubenstein), Isolde Freya Dick (now Isa Dick Hackett) (born March 15, 1967, to Dick and his fourth wife, Nancy Hackett), and Christopher Kenneth Dick (born July 25, 1973, to Dick and his fifth wife, Leslie "Tessa" Busby).

He transcribed what thoughts he could into an eight-thousand-page, one-million-word journal dubbed the Exegesis. From 1974 until his death in 1982, Dick spent many nights writing in this journal. A recurring theme in Exegesis is Dick's hypothesis that history had been stopped in the first century AD, and that "the Empire never ended". He saw Rome as the pinnacle of materialism and despotism, which, after forcing the Gnostics underground, had kept the population of Earth enslaved to worldly possessions. Dick believed that VALIS had communicated with him, and anonymously others, to induce the impeachment of U.S. President Richard Nixon, whom Dick believed to be the current Emperor of Rome incarnate. In a 1968 essay titled "Self Portrait", collected in the 1995 book The Shifting Realities of Philip K. Dick, Dick reflects on his work and lists which books he feels "might escape World War Three": Eye in the Sky, The Man in the High Castle, Martian Time-Slip, Dr. Bloodmoney, or How We Got Along After the Bomb, The Zap Gun, The Penultimate Truth, The Simulacra, The Three Stigmata of Palmer Eldritch (which he refers to as "the most vital of them all"), Do Androids Dream of Electric Sheep?, and Ubik. In a 1976 interview, Dick cited A Scanner Darkly as his best work, feeling that he "had finally written a true masterpiece, after 25 years of writing". Adaptations Films Several of Dick's stories have been made into films. Dick himself wrote a screenplay for an intended film adaptation of Ubik in 1974, but the film was never made. Many film adaptations have not used Dick's original titles. When asked why this was, Dick's ex-wife Tessa said, "Actually, the books rarely carry Phil's original titles, as the editors usually wrote new titles after reading his manuscripts. Phil often commented that he couldn't write good titles. If he could, he would have been an advertising writer instead of a novelist." Films based on Dick's writing had accumulated a total revenue of over US$1 billion by 2009. Blade Runner (1982), based on Dick's 1968 novel Do Androids Dream of Electric Sheep?, directed by Ridley Scott and starring Harrison Ford and Rutger Hauer. A screenplay had been in the works for years before Scott took the helm, with Dick being extremely critical of all versions. Dick was still apprehensive about how his story would be adapted for the film when the project was |
decent actress, especially here, where she's charming, moving and always believable. [...] There's one shot in particular, where Cruz enters a room in a greenish glow, which is right out of Hitchcock's picture [Vertigo]." 1998-2000: Early American film roles In 1998, Cruz appeared in her first American film as Billy Crudup's consolation-prize Mexican girlfriend in Stephen Frears' western film The Hi-Lo Country. Cruz stated that she had difficulties understanding people speaking English while she was filming The Hi-Lo Country. The film was critically and commercially unsuccessful. Kevin Lally of the Film Journal International commented in his review for the film that "in an ironic casting twist, the Spanish actress Penélope Cruz [...] is much more appealing as Josepha [than in her previous roles]". For her performance in the film, she was nominated for an ALMA Award for Best Actress. Also in 1998, Cruz appeared in Don Juan and the Spanish period drama The Girl of Your Dreams. In The Girl of Your Dreams (La niña de tus ojos), Cruz portrayed Macarena Granada, a singer who is in an on-and-off relationship with Antonio Resines's character Blas. They are part of a Francoist film troupe that travels from Spain during the Spanish Civil War to Nazi Germany for a joint production with UFA. Cruz's performance in the film was praised by film critics, with Jonathan Holloland of Variety magazine writing "if confirmation is still needed that Cruz is an actress first and a pretty face second, then here it is". A writer for Film4 commented that "Cruz herself is the inevitable focus of the film" but noted that overall the film "looks great". Cruz's role as Macarena has been viewed as her "largest role to date". For her performance, Cruz received a Goya Award and Spanish Actors' Union Award, and was nominated for a European Film Award. In 1999, Cruz worked with Almodóvar again in All About My Mother, playing Sister María Rosa Sanz, a pregnant nun with AIDS. The film received favorable reviews, and was commercially successful, grossing over $67 million worldwide, although it performed better at the box office internationally than domestically. In 2000, she appeared in Woman on Top in the lead female role as Isabelle, a world-class chef who suffered from motion sickness since birth, her first American lead role. Lisa Nesselson of Variety magazine praised the performances of both Cruz and her co-star, Harold Perrineau, saying they "burst off the screen", and added that Cruz has a charming accent. BBC News film critic Jane Crowther said that "Cruz is wonderfully ditzy as the innocent abroad" but remarked that "it's Harold Perrineau Jr as Monica who pockets the movie". Annlee Ellingson of Box Office magazine wrote "Cruz is stunning in the role—innocent and vulnerable yet possessing a mature grace and determined strength, all while sizzling with unchecked sensuality." Also in 2000, she played Alejandra Villarreal, who is Matt Damon's love interest in Billy Bob Thornton's film adaptation of the western bestselling novel All the Pretty Horses. Susan Stark of the Detroit News commented that in the film Thornton was able to guide Damon, Henry Thomas and Cruz to "their most impressive performances in a major movie yet". However, Bob Longigo of The Atlanta Journal Constitution was less enthusiastic about Cruz's and Damon's performance, saying that their "resulting onscreen chemistry would hardly warm a can of beans". 2001-2005: Breakthrough 2001 marked a turning point year when Cruz starred in the feature films Vanilla Sky and Blow. In Vanilla Sky, Cameron Crowe's interpretation of Open Your Eyes, she played Sofia Serrano, the love interest of Tom Cruise's character. The film received mixed reviews, but made $200 million worldwide. Her performance was well received by critics, with BBC film critic Brandon Graydon saying that Cruz "is an enchanting screen presence", and Ethan Alter of the Film Journal International noting that Cruz and her co-star Cruise were "able to generate some actual chemistry". Her next film was Blow, adapted from Bruce Porter's 1993 book Blow: How a Small Town Boy Made $100 million with the Medellín Cocaine Cartel and Lost It All. She had a supporting role as Mirtha Jung, the wife of Johnny Depp's character. The film received mixed reviews, but made $80 million worldwide. Nina Willdorf of the Boston Phoenix described Cruz as "multi-talented" and Mark Salvo of The Austin Chronicle wrote "I may be one of the last male holdouts to join the Cruz-Rules camp, but her tour de force performance here sucks you right in." In 2001, she also appeared in Don't Tempt Me, playing Carmen Ramos. The film received negative reviews. Jeff Vice of the Deseret News commented that "unfortunately, casting Cruz as a tough girl is a hilariously bad [idea]" and Michael Miller of the Village Voice writing that "as Satan's helper Carmen, Penélope Cruz doesn't hold a candle to her cocaine-huffing enabler in Blow". Cruz's last film in 2001 was Captain Corelli's Mandolin, film adaption of the novel of the same name. She played Pelagia, who falls in love with another man while her fiancé is in battle during the Second World War. Captain Corelli's Mandolin was not well received by critics, but made $62 million worldwide. In 2002, she had a minor role in Waking Up in Reno. It had negative reviews and was a box office failure, making $267,000 worldwide. The following year, Cruz had a supporting role in the horror film Gothika as Chloe Sava, a patient at a mental hospital. David Rooney of Variety wrote that Cruz "adds a serviceably malevolent edge to Chloe's apparent madness". Cruz's performance in Fanfan la Tulipe, also in 2003, was not well received, Peter Bradshaw of The Guardian commenting that Cruz "deserves a special Cannes Razzie for a performance of purest teak". In 2004, Cruz appeared in the Christmas film Noel as Nina, the girlfriend of Paul Walker's character and as Mia in the romantic drama Head in the Clouds, set in the 1930s. Head in the Clouds performed poorly at the box office. For Head in the Clouds, Bruce Birkland of Jam! Canoe said, "The story feels forced and the performances dreary, with the notable exception of Cruz, who seems to be in a different film from the rest of the cast." Desson Thompson of The Washington Post was more critical; his comment about the character's "pronounced limp" was that "Cruz (hardly the world's greatest actress) can't even perform without looking fake". She also starred in Sergio Castellitto's melodrama Don't Move. Cruz, who learned Italian for the role, won the David di Donatello for her performance. She also won the European Film Award for Best Actress for the film in 2004. In 2005, Cruz appeared as Dr. Eva Rojas in the action adventure Sahara. She earned $1.6 million for her supporting role. The film grossed $110 million worldwide but did not recoup its $160 million budget. Moviefone dubbed the film "one of the most famous flops in history" and in 2007, listed it at 24 on its list of "Biggest Box-Office Turkeys of All Time". Lori Hoffman of the Atlantic City Weekly felt Cruz put her "considerable [acting] skills on cruise control as Dr Eva Rojas" and James Berardnelli of ReelViews described Cruz's performance as a "black hole", that she "lacks screen presence". Also in 2005, Cruz appeared in Chromophobia, screened at the 2005 Cannes Film Festival and released the following year. Mathew Turner of View London said Cruz's character Gloria, a cancer-riddled prostitute, is "actually more interesting than the main storyline" while Time Evan's of Sky Movies wrote, "The Cruz/Ifans storyline—featuring the only two remotely sympathetic characters—never really fuses with the main plot." Her final 2005 film was Don't Move playing Italia. Eric Harrison of the Houston Chronicle noted that Cruz "goes all out" with her appearance and Patrick Peters of Empire magazine commented that the film's director, who also appears in the film, was able to draw a "sensitive performance" from Cruz. 2006-2009: Worldwide recognition Cruz appeared alongside her good friend Salma Hayek in the 2006 Western comedy film Bandidas. Randy Cordova of the Arizona Republic said the film "sports" Cruz and her co-star Salma Hayek as the "lusty dream team" and that they were the "marketing fantasy" for the film. Also in 2006, Cruz received favourable reviews for her performance as Raimunda, a working-class woman forced to go to great lengths to protect her 14-year-old daughter Paula, in Pedro Almodóvar's Volver. A.O. Scott of The New York Times remarked, "With this role Ms. Cruz inscribes her name near the top of any credible list of present-day flesh-and-blood screen goddesses, in no small part because she manages to be earthy, unpretentious and a little vulgar without shedding an ounce of her natural glamour." Likewise, Carina Chocano of The Los Angeles Times wrote, "Cruz, who has remarked that in Hollywood she's rarely allowed to be anything more than pretty, instills her with an awesome resoluteness and strength of character." She shared a Best Actress award at the 2006 Cannes Film Festival with five of her co-stars, as well as receiving a Goya Award and European Film Award, and was nominated for the Golden Globe, the Screen Actors Guild Award, the BAFTA Award, and the Academy Award for Best Actress in a leading role. She became the first and only Spanish actress ever nominated for an Academy Award. In 2007, Cruz appeared in the lead female role in Manolete, a biopic of bullfighter Manuel Laureano Rodríguez Sánchez, playing Antoñita "Lupe" Sino. The film was critically panned, and Variety felt that Cruz has "clearly been cast to play the kind of red-hot drama queen she's pulled off infinitely better in the films of Pedro Almodovar." After being shelved since 2007, Manolete (originally shot in 2005) released on demand via cable, satellite, telco and online on 7 June 2011 under the title A Matador's Mistress. She also appeared in The Good Night, playing two characters, Anna and Melody. TV Guide film critic Maitland McDonagh noted that in the film Cruz "expertly mines the contrast between chic, compliant, white-clad Anna and funky, street-wise Melody, who treats [Martin Freeman's character] Gary like the world-class drag he is". In 2008, Cruz starred alongside Ben Kingsley in Isabel Coixet's film Elegy, which was based on the Philip Roth story The Dying Animal, as the lead female role, Consuela Castillo. Ray Bennett of The Hollywood Reporter described Cruz's performance as being "outstanding in an otherwise lame male fantasy [film]." That same year, Cruz appeared in Woody Allen's Vicky Cristina Barcelona as María Elena, a mentally unstable woman, which was received with critical acclaim. Writing for the San Francisco Chronicle, Mick LaSalle noted, "But the revelation is Penélope Cruz, who has never been better in an American film. Suddenly, and for the first time, her stardom makes sense. As Maria Elena, José Antonio's gifted and neurotic ex-wife, Cruz is on fire - hysterically funny, abandoned, passionate, poignant, with a performance full of shading and wide in range. She's as fun and as powerful as Anna Magnani, and beautiful besides. Cruz just needed somebody to turn her loose." Likewise, Peter Bradshaw of The Guardian singled her out for praise, writing: "Cruz, playing Maria Elena, the passionate and crazy ex-wife of a moody Picasso-ish artist, looks as if she has wandered in from a more hefty film entirely; everything she does and says seems to mean more, count for more. This isn't to say that she gets bigger laughs, or perhaps any laughs, but she certainly walks off with the film". Cruz received a Goya Award and her first Academy Award and BAFTA Award for Best Supporting Actress. She also received a Golden Globe and SAG nomination. Cruz became the only Spanish actress ever to be awarded an Academy Award and the sixth Hispanic person to ever receive the award. Cruz's next film was the kid-friendly G-Force, voicing a guinea pig spy named Juarez. G-Force was a commercial success, making over $290 million worldwide. Also in 2009, she appeared in the film Broken Embraces as Lena. Stephanie Zacharek of Salon.com noted in her review for the film that Cruz "doesn't coast on her beauty in Broken Embraces, and she has the kind of role | and became a moderate commercial success at the international box offices. The same year, Cruz, along with Antonio Banderas, made a cameo appearance in Pedro Almodóvar's farcical comedy I'm So Excited, which marked a return to the director's light, campy comedies of the 1980s and 1990s. The film received mixed reviews, but earned a worldwide gross of more than US$11 million. In 2015, Cruz co-produced and starred in the Spanish drama film Ma Ma, directed by Julio Medem. In it, she plays Magda, a gutsy mother and unemployed teacher, who is diagnosed with breast cancer, a role which Cruz later cited as "one of the most complex, beautiful characters I've ever been offered, the most difficult." The melodrama was screened in the Special Presentations section of the 2015 Toronto International Film Festival, where it received generally negative reviews for its weepie story line. However, Cruz was praised for her "aces performance," which earned her an eighth Goya nomination at the 30th awards ceremony. 2016–present: Continued success Cruz's first film of 2016 was the American comedy Zoolander 2, co-starring and directed by Ben Stiller. In the sequel film, Cruz portrayed a secret Interpol agent who enlists models Derek Zoolander (Stiller) and Hansel McDonald, played by Owen Wilson, to help find out who is killing the world's most beautiful people. Specifically written for her persona, Cruz, a fan of the original 2001 film, was one of the first actors to be cast in their parts. Upon its release, the film received generally negative reviews from critics, who felt that it had "more celebrity cameos than laughs." Cruz's other film that year was Louis Leterrier's British spy comedy Grimsby, in which she played a powerful philanthropist, opposite Sacha Baron Cohen and Mark Strong. Cruz was reportedly offered $400,000 for her appearance in the film, which was released to generally mixed reviews from critics, who felt that the actress was highly underused and "looking even less invested here than she did in Zoolander 2." Also in 2016, Cruz reteamed with Fernando Trueba on his Spanish-language period pic The Queen of Spain, a sequel to Trueba's 1998 drama The Girl of Your Dreams. Set in the 1950s, twenty years after the events of the original film, Cruz reprised the role of an actress who became a Hollywood star and returns to Spain to film a blockbuster about Queen Isabella I of Castile. Selected to be shown in the Berlinale Special section of the 67th Berlin International Film Festival, the Spanish comedy-drama was screened to lukewarm reviews, but received five nominations at the 31st Goya Awards, earning Cruz her ninth nomination. Loving Pablo, a Spanish drama film directed by Fernando León de Aranoa was released in 2017, starring Cruz in the role of Virginia Vallejo, and her husband, Javier Bardem, in the role of Pablo Escobar. Based on Vallejo's bestselling memoir Loving Pablo, Hating Escobar, the film was launched to mixed reviews during the 74th Venice International Film Festival. In order to play the role of the Colombian journalist, Cruz studied hundreds of interviews of Vallejo. Cruz had a supporting role in Kenneth Branagh's Murder on the Orient Express (2017), the fourth adaptation of Agatha Christie's 1934 novel of the same name. The mystery–drama ensemble film follows world-renowned detective Hercule Poirot, who seeks to solve a murder on the famous European train in the 1930s. Cruz plays missionary and passenger Pilar Estravados, a Hispanic version of the novel's Swedish Greta Ohlsson. The film has grossed $306 million worldwide and received mixed to positive reviews from critics, with praise for the cast's performances, but criticism for not adding anything new to previous adaptations. In 2018, Cruz made her television debut by co-starring in the role of Donatella Versace in the second season of the FX anthology series American Crime Story entitled The Assassination of Gianni Versace. Her performance was highly praised by critics and she received a Primetime Emmy Award nomination for Outstanding Supporting Actress in a Limited Series or Movie. In addition, Cruz reteamed with Bardem on the Spanish-language psychological thriller film Everybody Knows, directed by Asghar Farhadi. In 2021, Cruz starred alongside Antonio Banderas in Gastón Duprat & Mariano Cohn's film Official Competition and reunited with Almodóvar for the film Parallel Mothers, in which she played Janis, a professional photographer entangled in a relationship with a married man, leading to an affair and resulting in her pregnancy. Both films premiered at the 78th Venice International Film Festival, where the latter received rave reviews. Parallel Mothers also screened at the 59th New York Film Festival, where it was received positively. Her performance in the film was lauded, winning the Volpi Cup for Best Actress and receiving her second Academy Award nomination for Best Actress, her fourth nomination overall. Stephanie Zacharek from Time stated that "Cruz is astonishing here, in what may be the best performance of her career so far. Janis' fragility and her fortitude are two sides of one coin, and Cruz can shift from one to the other in the merest breath." Owen Gleiberman of Variety mentioned that "Cruz acts this part with a mood-shifting immediacy that leaves you breathless", with David Rooney of The Hollywood Reporter describing her performance as "one of the best roles of her career" and "her most outstanding work since Volver." Following the release of these films, she was honoured at the Museum of Modern Art in New York for her career and achievements in film. Luxury fashion house Chanel returned as the presenting sponsor making for an in-sync affair, as Cruz has served as ambassador for the brand since 2018. The following year, she appeared in the female-led spy action film The 355, directed by Simon Kinberg and starring alongside Jessica Chastain, Lupita Nyongo, Diane Kruger, Fan Bingbing, Sebastian Stan, and Édgar Ramírez. The film was released by Universal Pictures on January 7, 2022. Cruz is set to appear and serve as producer in the thriller film On the Fringe, the directorial feature debut of Juan Diego Botto. She is also attached to star alongside Adam Driver and Shailene Woodley in the biopic Ferrari, directed by Michael Mann. The film will chronicle the life of Enzo Ferrari, founder of the Ferrari brand. Cruz is set to portray Ferrari's wife, Laura. Public image In 2006, Cruz became a spokesmodel for French cosmetics company L'Oréal to promote products such as the L'Oréal Paris hair dye Natural Match and L'Oreal mascara products. She receives US$2 million a year for her work for the company. Cruz has appeared in print ads for Mango and had a contract with Ralph Lauren in 2001. Cruz and her sister designed their second collection for Mango in 2007. It was inspired by Brigitte Bardot and summers in St Tropez. Cruz ranked as No. 58 in Maxim "Hot 100" of 2007 list, and was chosen by Empire magazine as being one of the 100 Sexiest Movie Stars in the world. Cruz was also ranked on Askmen.com's Most Desirable Women of 2008 at No. 26, in 2009 at No. 25, and in 2010 at No. 7. In April 2010, she replaced Kate Winslet as the new face and ambassador of Lancôme's Trésor fragrance. Lancôme signed Cruz as their third superstar spokesmodel, along with Julia Roberts and Winslet. The campaign was shot by Mario Testino at Paris's Hotel de Crillon and debuted in the autumn of 2010. In 2010, Cruz was a guest editor for the French Vogue magazine, focusing on larger-size models in a provocative photo shoot. Almodóvar described her as his muse. On the cover of Spanish Vogue's December 2010 issue, she agreed to be photographed by fashion photographer Peter Lindbergh only if her pregnancy was not shown. In 2011, The Telegraph reported the most sought after body parts of the rich and famous revealed by two Hollywood plastic surgeons who carried out a survey among their patients to build up the picture of the perfect woman. Under the category of the most sought after body shape, Penélope Cruz, known for her voluptuous figure, was voted as having the top body. Men's Health ranked her at No. 32. on their "100 Hottest Women of All-Time" list. Esquire named her the Sexiest Woman Alive in 2014. Philanthropy Cruz has donated money and time to charity. In addition to work in Nepal, she has volunteered in Uganda and India, where she spent a week working with Mother Teresa that included assisting in a leprosy clinic. That trip inspired Cruz to help start a foundation to support homeless girls in India, where she sponsors two young women. She donated her salary from her first Hollywood film, The Hi-Lo Country, to Mother Teresa's mission. In the early 2000s, she spent time in Nepal photographing Tibetan children for an exhibition attended by the Dalai Lama. She also photographed residents at the Pacific Lodge Boys' Home, most of whom are former gang members and recovering substance abusers. She said: "These kids break my heart. I have to control myself not to cry. Not out of pity, but seeing how tricky life is and how hard it is to make the right choices." A pregnant Cruz showed her support for the battle against AIDS by lighting up the Empire State Building with red lights in New York City on 1 December 2010 on International AIDS Day, as part of (RED)'s new awareness campaign, 'An AIDS Free Generation is Due in 2015,' which aims to eradicate the HIV virus from pregnant mothers to their babies. In 2012 and 2018, she posed for ads supporting PETA's anti-fur campaign. Personal life Cruz is married to Spanish actor Javier Bardem. Bardem was her co-star in her breakthrough role as Silvia in Jamón, Jamón (1992), as well as starring alongside her in Vicky Cristina Barcelona (2008). They were also both in the 2013 film The Counselor, as well as in Everybody Knows in 2018. Cruz began dating Bardem in 2007 and they married in early July 2010 in a private ceremony at a friend's home in the Bahamas. They have a son named Leo Encinas Cruz who was born in January 2011 in Los Angeles, and a daughter named Luna Encinas Cruz who was born in July 2013 in Madrid. She became an advocate of breastfeeding in public following the birth of her children. Cruz had a three-year relationship with Tom Cruise after they appeared together in Vanilla Sky (2001). The relationship ended in January 2004. In June 2003, Cruz settled a defamation lawsuit against Australian magazine New Idea over an article it published about her relationship with Cruise; the publication had to apologize, pay her legal costs, and donate AU$5,000 (US$3,200) to her nominated charity. Known to friends as Pe, Cruz owns a clothing store in Madrid, and designed jewelry and handbags with her younger sister for a company in Japan. In 2009, Cruz signed a petition that called for the release of filmmaker Roman Polanski during his arrest in Switzerland for his 1977 charge for drugging and raping a 13-year-old girl.

arraignment at which the charges are formally presented to the defendant. In many states criminal charges may be commenced with the prosecutor's filing an "information" with the court, a document that describes basic facts alleged to constitute a criminal offense by the defendant and the criminal laws that the defendant is alleged to have violated. The defendant will then be scheduled for an arraignment at which the charge is formally presented. If the defendant does not plead guilty at the arraignment, the court schedules a preliminary hearing. Where an indictment is obtained through means other than an information, such as through grand jury proceedings or after an arrest when the defendant is first brought to court, the arraignment may be described using terms such as "initial hearing", or "preliminary arraignment", creating the possibility of confusing with a preliminary hearing as described article. Those other hearings are not probable cause hearings. State law A preliminary hearing is not always required, and its requirement varies by jurisdiction. In the U.S., for example, some states hold preliminary hearings in every serious criminal case; in others, they are held upon request by the defense, and still others, they are only held in felony | trial. Preliminary inquiries are only held when a person is charged with an indictable offence. The Crown Attorney may call witnesses. If there is not enough evidence, the court will dismiss the charge(s). In the aftermath of the 2016 Jordan decision, in which the Supreme Court of Canada imposed time limits on the Crown to bring criminal cases to trial, the Crown has started to use the direct indictment procedure more frequently. Scotland In Scotland, a preliminary hearing is a non-evidential diet in cases to be tried before the High Court of Justiciary. It is a pre-trial diet to enable the court to be advised whether both parties, the prosecution and the defence, are ready to proceed to trial and may also deal with ancillary procedural matters. United States In the United States, at a preliminary hearing the judge must find that such evidence provides probable cause to believe that the crime was committed, and that the crime was committed by the defendant. There is a right to counsel at the preliminary hearing. The conduct of the preliminary hearing as well as the specific rules regarding the admissibility of evidence vary from jurisdiction to jurisdiction. Hearsay is typically allowed. If the court decide that there is probable cause, a formal charging instrument (called the information in some jurisdictions) will be issued; and the prosecution will continue. If the court should find there is no probable cause, then typically the prosecution will cease. Many jurisdictions, however, allow the prosecution to seek a new preliminary hearing, or even seek a bill of indictment from a grand jury. The key questions that a preliminary hearing normally addresses are: Is there probable cause to believe the alleged crime occurred and did it occur within the court's jurisdiction? Is there probable cause to believe that the defendant committed the crime? If a judge determines that there is sufficient evidence to believe that the defendant committed the crime, it is said that the defendant is "held to answer" or "bound over" (in U.S. |
specimens. In 1881 he published a new urine test which could be used to distinguish various types of typhoid from simple cases of diarrhea. The intensity of staining made possible a disease prognosis. The pigment solution he used is known today as Ehrlich's reagent. Ehrlich's great achievement, but also a source of problems during his further career, was that he had initiated a new field of study interrelating chemistry, biology and medicine. Much of his work was rejected by the medical profession, which lacked the requisite chemical knowledge. It also meant that there was no suitable professorship in sight for Ehrlich. Serum research Friendship with Robert Koch When a student in Breslau, Ehrlich was given an opportunity by the pathologist Julius Friedrich Cohnheim to conduct extensive research and was also introduced to Robert Koch, who was at the time a district physician in Wollstein, Posen Province. In his spare time, Koch had clarified the life cycle of the anthrax pathogen and had contacted Ferdinand Cohn, who was quickly convinced by Koch's work and introduced him to his Breslau colleagues. From 30 April to 2 May 1876, Koch presented his investigations in Breslau, which the student Paul Ehrlich was able to attend. On 24 March 1882, Ehrlich was present when Robert Koch, working since 1880 at the Imperial Public Health Office (Kaiserliches Gesundheitsamt) in Berlin, presented the lecture in which he reported how he was able to identify the tuberculosis pathogen. Ehrlich later described this lecture as his "greatest experience in science". The day after Koch's lecture, Ehrlich had already made an improvement to Koch's staining method, which Koch unreservedly welcomed. From this date on, the two men were bound in friendship. In 1887 Ehrlich became an unsalaried lecturer in internal medicine (Privatdozent für Innere Medizin) at Berlin University, and in 1890 took over the tuberculosis station at a public hospital in Berlin-Moabit at Koch's request. This was where Koch's hoped-for tuberculosis therapeutic agent tuberculin was under study; and Ehrlich had even injected himself with it. In the ensuing tuberculin scandal, Ehrlich tried to support Koch and stressed the value of tuberculin for diagnostic purposes. In 1891 Koch invited Ehrlich to work at the newly founded Institute of Infectious Diseases (Institut für Infektionskrankheiten – now the Robert Koch Institute) at Friedrich-Wilhelms-Universität (now Humboldt University) in Berlin. Koch was unable to give him any remuneration, but did offer him full access to laboratory staff, patients, chemicals and laboratory animals, which Ehrlich always remembered with gratitude. First work on immunity Ehrlich had started his first experiments on immunization already in his private laboratory. He accustomed mice to the poisons ricin and abrin. After feeding them with small but increasing dosages of ricin he ascertained that they had become "ricin-proof". Ehrlich interpreted this as immunization and observed that it was abruptly initiated after a few days and was still in existence after several months, but mice immunized against ricin were just as sensitive to abrin as untreated animals. This was followed by investigations on the "inheritance" of acquired immunity. It was already known that in some cases after a smallpox or syphilis infection, specific immunity was transmitted from the parents to their offspring. Ehrlich rejected inheritance in the genetic sense because the offspring of a male mouse immunized against abrin and an untreated female mouse were not immune to abrin. He concluded that the fetus was supplied with antibodies via the pulmonary circulation of the mother. This idea was supported by the fact that this "inherited immunity" decreased after a few months. In another experiment he exchanged the offspring of treated and untreated female mice. The mice which were nursed by the treated females were protected from the poison, providing the proof that antibodies can also be conveyed in milk. Ehrlich also researched autoimmunity, but he specifically rejected the possibility that an organism's immune system could attack the organism's own tissue calling it "horror autotoxicus". It was Ehrlich's student, Ernest Witebsky, who demonstrated that autoimmunity could cause disease in humans. Ehrlich was the first to propose that regulatory mechanisms existed to protect an organism from autoimmunity, saying in 1906 that "the organism possesses certain contrivances by means of which the immunity reaction, so easily produced by all kinds of cells, is prevented from acting against the organism's own elements". Work with Behring on a diphtheria serum Emil Behring had worked at the Berlin Institute of Infectious Diseases until 1893 on developing an antiserum for treating diphtheria and tetanus but with inconsistent results. Koch suggested that Behring and Ehrlich cooperate on the project. This joint work was successful to the extent that Ehrlich was quickly able to increase the level of immunity of the laboratory animals based on his experience with mice. Clinical tests with diphtheria serum early in 1894 were successful and in August the chemical company Hoechst started to market Behring's "Diphtheria Remedy synthesized by Behring-Ehrlich". The two discoverers had originally agreed to share any profits after the Hoechst share had been subtracted. Their contract was changed several times and finally Ehrlich was eventually pressured into accepting a profit share of only eight percent. Ehrlich resented what he considered as unfair treatment, and his relationship with Behring was thereafter problematic, a situation which later escalated over the issue of the valency of tetanus serum. Ehrlich recognized that the principle of serum therapy had been developed by Behring and Kitasato. But he was of the opinion that he had been the first to develop a serum which could also be used on humans, and that his role in developing the diphtheria serum had been insufficiently acknowledged. Behring, for his part, schemed against Ehrlich at the Prussian Ministry of Culture, and from 1900 on Ehrlich refused to collaborate with him. von Behring was the sole recipient of the first Nobel Prize in Medicine, in 1901, for contributions to research on diphtheria. The valency of serums Since antiserums were an entirely new type of medicine whose quality was highly variable, a government system was established to guarantee their safety and effectiveness. Beginning 1 April 1895, only government-approved serum could be sold in the German Reich. The testing station for diphtheria serum was provisionally housed at the Institute of Infectious Diseases. At the initiative of Friedrich Althoff, an Institute of Serum Research and Testing (Institut für Serumforschung und Serumprüfung) was established in 1896 in Berlin-Steglitz, with Paul Ehrlich as director (which required him to cancel all his contracts with Hoechst). In this function and as honorary professor at Berliner University he had annual earnings of 6,000 marks, approximately the salary of a university professor. In addition to a testing department the institute also had a research department. In order to determine the effectiveness of diphtheria antiserum, a stable concentration of diphtheria toxin was required. Ehrlich discovered that the toxin being used was perishable, in contrast to what had been assumed, which for him led to two consequences: He did not use the toxin as a standard, but instead a serum powder developed by Behring, which had to be dissolved in liquid shortly before use. The strength of a test toxin was first determined in comparison with this standard. The test toxin could then be used as a reference for testing other serums. For the test itself, toxin and serum were mixed in a ratio so that their effects just cancelled each other when injected into a guinea pig. But since there was a large margin in determining whether symptoms of illness were present, Ehrlich established an unambiguous target: the death of the animal. The mixture was to be such that the test animal would die after four days. If it died earlier, the serum was too weak and was rejected. Ehrlich claimed to have made the determination of the valency of serum as accurate as it would be with chemical titration. This again demonstrates his tendency to quantify the life sciences. Influenced by the mayor of Frankfurt am Main, Franz Adickes, who endeavored to establish science institutions in Frankfurt in preparation of the founding of a university, Ehrlich's institute moved to Frankfurt in 1899 and was renamed the Royal Prussian Institute of Experimental Therapy (Königlich Preußisches Institut für Experimentelle Therapie). The German quality-control methodology was copied by government serum institutes all over the world, and they also obtained the standard serum from Frankfurt. After diphtheria antiserum, tetanus serum and various bactericide serums for use in veterinary medicine were developed in rapid sequence. These were also evaluated at the institute, as was tuberculin and later on various vaccines. Ehrlich's most important colleague at the institute was the Jewish doctor and biologist Julius Morgenroth. Ehrlich’s side-chain theory He postulated that cell protoplasm contains special structures which have chemical side chains (today's term is macromolecules) to which the toxin binds, affecting function. If the organism survives the effects of the toxin, the blocked side-chains are replaced by new ones. This regeneration can be trained, the name for this phenomenon being immunization. If the cell produces a surplus of side chains, these might also be released into the blood as antibodies. In the following years Ehrlich expanded his side chain theory using concepts ("amboceptors", "receptors of the first, second and third order", etc.) which are no longer customary. Between the antigen and the antibody he assumed there was an additional immune molecule, which he called an "additive" or a "complement". For him, the side chain contained at least two functional groups. For providing a theoretical basis for immunology as well as for his work on serum valency, Ehrlich was awarded the Nobel Prize for Physiology or Medicine in 1908 together with Élie Metchnikoff. Metchnikoff, who had researched the cellular branch of immunity, Phagocytosis, at the Pasteur Institute had previously sharply attacked Ehrlich. Cancer research In 1901, the Prussian Ministry of Finance criticized Ehrlich for exceeding his budget and as | Royal Prussian Institute of Experimental Therapy (Königlich Preußisches Institut für Experimentelle Therapie). The German quality-control methodology was copied by government serum institutes all over the world, and they also obtained the standard serum from Frankfurt. After diphtheria antiserum, tetanus serum and various bactericide serums for use in veterinary medicine were developed in rapid sequence. These were also evaluated at the institute, as was tuberculin and later on various vaccines. Ehrlich's most important colleague at the institute was the Jewish doctor and biologist Julius Morgenroth. Ehrlich’s side-chain theory He postulated that cell protoplasm contains special structures which have chemical side chains (today's term is macromolecules) to which the toxin binds, affecting function. If the organism survives the effects of the toxin, the blocked side-chains are replaced by new ones. This regeneration can be trained, the name for this phenomenon being immunization. If the cell produces a surplus of side chains, these might also be released into the blood as antibodies.

Metchnikoff, who had researched the cellular branch of immunity, Phagocytosis, at the Pasteur Institute had previously sharply attacked Ehrlich. Cancer research In 1901, the Prussian Ministry of Finance criticized Ehrlich for exceeding his budget and as a consequence reduced his income. In this situation Althoff arranged a contact with Georg Speyer, a Jewish philanthropist and joint owner of the bank house Lazard Speyer-Ellissen. The cancerous disease of Princess Victoria, the widow of the German Emperor Friedrich II, had received much public attention and prompted a collection among wealthy Frankfurt citizens, including Speyer, in support of cancer research. Ehrlich had also received from the German Emperor Wilhelm II a personal request to devote all his energy to cancer research. Such efforts led to the founding of a department for cancer research affiliated with the Institute of Experimental Therapy. The chemist Gustav Embden, among others, worked there. Ehrlich informed his sponsors that cancer research meant basic research, and that a cure could not be expected soon. Among the results achieved by Ehrlich and his research colleagues was the insight that when tumors are cultivated by transplanting tumor cells, their malignancy increases from generation to generation. If the primary tumor is removed, then metastasis precipitously increases. Ehrlich applied bacteriological methods to cancer research. In analogy to vaccination, he attempted to generate immunity to cancer by injecting weakened cancer cells. Both in cancer research and chemotherapy research (see below) he introduced the methodologies of Big Science. Chemotherapy In vivo staining In 1885 Ehrlich's monograph "The Need of the Organism for Oxygen" (Das Sauerstoffbedürfnis des Organismus- Eine farbenanalytische Studie) appeared, which he also submitted as a habilitation thesis. In it he introduced the new technology of in vivo staining. One of his findings was that pigments can only be easily assimilated by living organisms if they are in granular form. He injected the dyes alizarin blue and indophenol blue into laboratory animals and established after their death that various organs had been colored to different degrees. In organs with high oxygen saturation, indophenol was retained; in organs with medium saturation, indophenol was reduced, but not alizarin blue. And in areas with low oxygen saturation, both pigments were reduced. With this work, Ehrlich also formulated the conviction which guided his research: that all life processes can be traced to processes of physical chemistry occurring in the cell. Methylene blue In the course of his investigations Ehrlich came across methylene blue, which he regarded as particularly suitable for staining bacteria. Later, Robert Koch also used methylene blue as a dye in his research on the tuberculosis pathogen. In Ehrlich's view, an added benefit was that methylene blue also stained the long appendages of nerve cells, the axons. He initiated a doctoral dissertation on the subject, but did not follow up the topic himself. It was the opinion of the neurologist Ludwig Edinger that Ehrlich had thereby opened up a major new topic in the field of neurology. After mid-1889, when Ehrlich was unemployed, he privately continued his research on methylene blue. His work on in vivo staining gave him the idea of using it therapeutically. Since the parasite family of Plasmodiidae – which includes the malaria pathogen – can be stained with methylene blue, he thought it could possibly be used in the treatment of malaria. In the case of two patients so treated at the city hospital in Berlin-Moabit, their fever indeed subsided and the malaria plasmodia disappeared from their blood. Ehrlich obtained methylene blue from the company Meister Lucius & Brüning AG (later renamed Hoechst AG), which started a long collaboration with this company. The search for a chemotherapia specifica Before the Institute of Experimental Therapy had moved to Frankfurt, Ehrlich had already resumed work on methylene blue. After the death of Georg Speyer, his widow Franziska Speyer endowed the Georg-Speyer House in his memory which was erected next door to Ehrlich's institute. As director of the Georg-Speyer House, Ehrlich transferred his chemotherapeutic research there. He was looking for an agent which was as effective as methylene blue, but without its side effects. His model was on the one hand the impact of quinine on malaria, and on the other hand, in analogy to serum therapy, he thought there must also be chemical pharmaceuticals which would have just as specific an effect on individual diseases. His goal was to find a "Therapia sterilisans magna", in other words a treatment that could kill all disease pathogens. As a model for experimental therapy Ehrlich used a guinea pig disease trypanosoma and tested out various chemical substances on laboratory animals. The trypanosomes could indeed be successfully killed with the dye trypan red. Beginning in 1906, he intensively investigated atoxyl and had it tested by Robert Koch along with other arsenic compounds during Koch's sleeping sickness expedition of 1906/07. Although the name literally means "nonpoisonous", atoxyl does cause damage, especially to the optic nerve. Ehrlich elaborated the systematic testing of chemical compounds in the sense of screening as now practiced in the pharmaceutical industry. He discovered that Compound 418 - Arsenophenylglycine - had an impressive therapeutic effect and had it tested in Africa. With the support of his assistant Sahachiro Hata Ehrlich discovered in 1909 that Compound 606, Arsphenamine, effectively combatted "spirillum" spirochaetes bacteria, one of whose subspecies causes syphilis. The compound proved to have few side effects in human trials, and the spirochetes disappeared in seven syphilis patients after this treatment. After extensive clinical testing (all the research participants had the negative example of tuberculin in mind) the Hoechst company began to market the compound toward the end of 1910 under the name Salvarsan. This was the first agent with a specific therapeutic effect to be created on the basis of theoretical considerations. Salvarsan proved to be amazingly effective, particularly when compared with |
Examples of systematic philosophers include Plato, Aristotle, Descartes, Spinoza, and Hegel. In many ways, any attempts to formulate a philosophical method that provides the ultimate constituents of reality, a metaphysics, can be considered systematic philosophy. In modern philosophy the reaction to systematic philosophy began with Kierkegaard and continued in various forms through analytic philosophy, existentialism, hermeneutics, and deconstructionism. Some common features of the methods that philosophers follow (and discuss when discussing philosophical method) include: Methodic doubt - a systematic process of being skeptical about (or doubting) the truth of one's beliefs. Argument - provide an argument or several arguments supporting the solution. Dialectic - present the solution and arguments for criticism by other philosophers, and help them judge their own. Doubt and the sense of wonder Plato said that "philosophy begins in wonder", a view which is echoed by Aristotle: "It was their wonder, astonishment, that first led men to philosophize and still leads them." Philosophizing may begin with some simple doubts about accepted beliefs. The initial impulse to philosophize may arise from suspicion, for example, that we do not fully understand, and have not fully justified, even our most basic beliefs about the world. Formulate questions and problems Another element of a philosophical method is to formulate questions to be answered or problems to be solved. The working assumption is that the more clearly the question or problem is stated, the easier it is to identify critical issues. A relatively small number of major philosophers prefer not to be quick, but to spend more time trying to get extremely clear on what the problem is all about. Enunciate a solution Another approach is to enunciate a theory, or to offer a definition or analysis, which constitutes an attempt to solve a philosophical problem. Sometimes a philosophical theory by itself can be stated quite briefly. All the supporting philosophical text is offered by way of hedging, explanation, and argument. Not all proposed solutions to philosophical problems consist of definitions or generalizations. Sometimes, what is called for, is a certain sort of explanation — not a causal explanation, but an explanation for example of how two different views, which seem to be contrary to one another, can be held at the same time, consistently. One can call this a philosophical explanation. Justify the solution An argument is a set of statements, one of which (the conclusion), it is said or implied, follows from the others (the premises). One might think of arguments as bundles of reasons — often not just a list, but logically interconnected statements — followed by the claim they are reasons for. The reasons are the premises, the claim they support is the conclusion; together they make an argument. Philosophical arguments and justifications are another important part of the philosophical method. It is rare to find a philosopher, particularly in the Western philosophical tradition, who lacks many arguments. Philosophers are, or at least are expected to be, very good at giving arguments. They constantly demand and offer arguments for different claims they make. This, therefore, indicates that philosophy is a quest for arguments. A good argument — a clear, organized, and sound statement of reasons — may ultimately cure the original doubts that motivated | or analysis, which constitutes an attempt to solve a philosophical problem.

A good argument — a clear, organized, and sound statement of reasons — may ultimately cure the original doubts that motivated us to take up philosophy. If one is willing to be satisfied without any good supporting reasons, then a Western philosophical approach may not be what one actually requires. Philosophical criticism In philosophy concerning the most fundamental aspects of the universe, the experts all disagree. It follows that another element of philosophical method, common in the work of nearly all philosophers, is philosophical criticism. It is this that makes much philosophizing a social endeavor. Philosophers offer definitions and explanations in solution to problems; they argue for those solutions; and then other philosophers provide counter arguments, expecting to eventually come up with better solutions. This exchange and resulting revision of views is called dialectic. Dialectic (in one sense of this history-laden word) is simply philosophical conversation amongst people who do not always agree with each other about everything. One can do this sort of harsh criticism on one's own, but others can help greatly, if important assumptions are shared with the person offering the criticisms. Others are able to think of criticisms |
Crocodile The Skeleton The Doctor Characters once regular but now occasional include: Toby the Dog The Ghost The Lawyer Hector the Horse Pretty Polly The Hangman (a.k.a. Jack Ketch) The Devil The Beadle Jim Crow ("The Black Man") Mr. Scaramouche The Servant (or "The Minstrel") The Blind Man Other characters included Boxers, Chinese Plate Spinners, topical figures, a trick puppet with an extending neck (the "Courtier"), and a monkey. A live Toby the Dog was once a regular featured novelty routine, sitting on the playboard and performing "with" the puppets. Punch wears a brightly coloured (traditionally red) jester's motley and sugarloaf hat with a tassel. He is a hunchback whose hooked nose almost meets his curved, jutting chin. He carries a stick (called a slapstick) as large as himself, which he freely uses upon most of the other characters in the show. Judy wears an apron, a blue dress, and a bonnet and always tries to tell Punch off when he uses the slapstick Story Glyn Edwards has likened the story of Punch and Judy to the story of Cinderella. He points out that there are parts of the Cinderella story which everyone knows, namely the cruel step sisters, the invitation to the ball, the handsome prince, the fairy godmother, Cinderella's dress turning to rags at midnight, the glass slipper left behind, the prince searching for its owner, and the happy ending. None of these elements can be omitted and the famous story still be told. The same principle applies to Punch and Judy. Everyone knows that Punch mishandles the baby, that Punch and Judy quarrel and fight, that a policeman comes for Punch and gets a taste of his stick, that Punch has a gleeful run-in with a variety of other figures and takes his stick to them all, that eventually he faces his final foe (which might be a hangman, the devil, a crocodile, or a ghost). Edwards contends that a proper Punch and Judy show requires these elements or the audience will feel let down. Peter Fraser writes, "the drama developed as a succession of incidents which the audience could join or leave at any time, and much of the show was impromptu." This was elaborated by George Speaight, who explained that the plotline "is like a story compiled in a parlour game of Consequences ... the show should, indeed, not be regarded as a story at all but a succession of encounters." Robert Leach makes it clear that "the story is a conceptual entity, not a set text: the means of telling it, therefore, are always variable." Rosalind Crone asserts that the story needed to be episodic so that passersby on the street could easily join or leave the audience during a performance. Much emphasis is often placed on the first printed script of Punch and Judy, in 1827. It was based on a show by travelling performer Giovanni Piccini, illustrated by George Cruikshank, and written by John Payne Collier. This is the only surviving script of a performance, and its accuracy is questioned. The performance was stopped frequently to allow Collier and Cruikshank to write and sketch and, in the words of Speaight, Collier is someone of whom "the full list of his forgeries has not yet been reckoned, and the myths he propagated are still being repeated. (His) 'Punch and Judy' is to be warmly welcomed as the first history of puppets in England, but it is also sadly to be examined as the first experiment of a literary criminal." The tale of Punch and Judy varies from puppeteer to puppeteer, as previously with Punchinello and Joan, and it has changed over time. Nonetheless, the skeletal outline is often recognizable. It typically involves Punch behaving outrageously, struggling with his wife Judy and the baby, and then triumphing in a series of encounters with the forces of law and order (and often the supernatural), interspersed with jokes and songs. Typical 21st-century performance A typical show as performed currently in the UK will start with the arrival of Mr. Punch, followed by the introduction of Judy. They may well kiss and dance before Judy requests Mr. Punch to look after the baby. Punch will fail to carry out this task appropriately. It is rare for Punch to hit his baby these days, but he may well sit on it in a failed attempt to "babysit", or drop it, or even let it go through a sausage machine. In any event, Judy will return, will be outraged, will fetch a stick, and the knockabout will commence. A policeman will arrive in response to the mayhem and will himself be felled by Punch's slapstick. All this is carried out at breakneck farcical speed with much involvement from a gleefully shouting audience. From here on anything goes. Joey the Clown might appear and suggest, "It's dinner time." This will lead to the production of a string of sausages, which Mr. Punch must look after, although the audience will know that this really signals the arrival of a crocodile whom Mr. Punch might not see until the audience shouts out and lets him know. Punch's subsequent comic struggle with the crocodile might then leave him in need of a Doctor who will arrive and attempt to treat Punch by walloping him with a stick until Punch turns the tables on him. Punch may next pause to count his "victims" by laying puppets on the stage, only for Joey the Clown to move them about behind his back in order to frustrate him. A ghost might then appear and give Mr. Punch a fright before it too is chased off with a slapstick. In more uncritical times, a hangman would arrive to punish Mr. Punch, only to himself be tricked into sticking his head in the noose. "Do you do the hanging?" is a question often asked of performers. Some will include it where circumstances warrant (such as for an adult audience) but most do not. Some will choose to include it whatever the circumstances and will face down any critics. Finally, the show will often end with the Devil arriving for Mr. Punch (and possibly threatening his audience as well). Punch—in his final gleefully triumphant moment—will win his fight with the Devil, bring the show to a rousing conclusion, and earn a round of applause. Plots reflect their own era Punch and Judy might follow no fixed storyline, as with the tales of | at both his Punch's Theatre at Covent Garden and earlier in provincial Bath, Somerset. Powell has been credited with being "largely responsible for the form taken by the drama of Punch and Judy". In 1721, a puppet theatre opened in Dublin that ran for decades. The cross-dressing actress Charlotte Charke ran the successful but short-lived Punch's Theatre in the Old Tennis Court at St. James's, Westminster, presenting adaptations of Shakespeare as well as plays by herself, her father Colley Cibber, and her friend Henry Fielding. Fielding eventually ran his own puppet theatre under the pseudonym Madame de la Nash to avoid the censorship concomitant with the Theatre Licensing Act of 1737. Punch was extremely popular in Paris and, by the end of the 18th century, he was also playing in Britain's American colonies, where even George Washington bought tickets for a show. However, marionette productions were expensive and cumbersome to mount and transport, presented in empty halls, the back rooms of taverns, or within large tents at England's yearly agricultural events at Bartholomew Fair and Mayfair. In the latter half of the 18th century, marionette companies began to give way to glove-puppet shows, performed from within a narrow, lightweight booth by one puppeteer, usually with an assistant, or "bottler," to gather a crowd and collect money. These shows might travel through country towns or move from corner to corner along busy London streets, giving many performances in a single day. The character of Punch adapted to the new format, going from a stringed comedian who might say outrageous things to a more aggressive glove-puppet who could do outrageous—and often violent—things to the other characters. The mobile puppet booth of the late 18th- and early 19th-century Punch and Judy glove-puppet show could be easily fitted-up and was originally covered in checked bed ticking or whatever inexpensive cloth might come to hand. Later Victorian booths were gaudier affairs, particularly those used for Christmas parties and other indoor performances. In the 20th century, however, red-and-white-striped puppet booths became iconic features on the beaches of many English seaside and summer holiday resorts. Such striped cloth is the most common covering today, wherever the show might be performed. A more substantial change came over time to the show's target audience. The show was originally intended for adults, but it changed into primarily a children's entertainment in the late Victorian era. Ancient members of the show's cast ceased to be included, such as the Devil and Punch's mistress "Pretty Polly," when they came to be seen as inappropriate for young audiences. The story changes, but some phrases remain the same for decades or even centuries. For example, Punch dispatches his foes each in turn and still squeaks his famous catchphrase: "That's the way to do it!" The term "pleased as Punch" is derived from Punch and Judy; specifically, Mr. Punch's characteristic sense of gleeful self-satisfaction. Modern British performances of Punch and Judy are no longer exclusively the traditional seaside children's entertainments which they had become. They can now be seen at carnivals, festivals, birthday parties, and other celebratory occasions. The association of Punch with the seaside is still very strong however, as demonstrated by Wisbech Town council's annual Wis-BEACH day each summer, "all the seaside favourites are on show, including a donkey, deck chairs, Punch and Judy and fish and chips" Characters The characters in a Punch and Judy show are not fixed. They are similar to the cast of a soap opera or a folk tale such as Robin Hood: the principal characters must appear, but the lesser characters are included at the discretion of the performer. New cast may be added and older cast dropped as the tradition changes. Along with Punch and Judy, the cast of characters usually includes their baby, a hungry crocodile, a clown, an officious policeman, and a prop string of sausages. The devil and the generic hangman Jack Ketch may still make their appearances but, if so, Punch will always get the better of them. The cast of a typical Punch and Judy show today will include: Mr. Punch Judy The Baby The Constable (a.k.a. Policeman Jack) Joey the Clown The Crocodile The Skeleton The Doctor Characters once regular but now occasional include: Toby the Dog The Ghost The Lawyer Hector the Horse Pretty Polly The Hangman (a.k.a.

to Ten (low). In contrast to this version of poker, seven-card stud only appeared in the middle of the 19th century, and was largely spread by the US military. It became a staple in many casinos following the second world war, and grew in popularity with the advent of the World Series of Poker in the 1970s. Texas Hold 'Em and other community card games began to dominate the gambling scenes over the next couple of decades. The televising of poker was a particularly strong influence increasing the popularity of the game during the turn of the millennium, resulting in the poker boom a few years later between 2003 and 2006. Today the game has grown to become an extremely popular pastime worldwide. Gameplay In casual play, the right to deal a hand typically rotates among the players and is marked by a token called a dealer button (or buck). In a casino, a house dealer handles the cards for each hand, but the button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting. The cards are dealt clockwise around the poker table, one at a time. One or more players are usually required to make forced bets, usually either an ante or a blind bet (sometimes both). The dealer shuffles the cards, the player on the chair to his or her right cuts, and the dealer deals the appropriate number of cards to the players one at a time, beginning with the player to his or her left. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot. At any time during a betting round, if one player bets, no opponents choose to call (match) the bet, and all opponents instead fold, the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This is what makes bluffing possible. Bluffing is a primary feature of poker, distinguishing it from other vying games and from other games that use poker hand rankings. At the end of the last betting round, if more than one player remains, there is a showdown, in which the players reveal their previously hidden cards and evaluate their hands. The player with the best hand according to the poker variant being played wins the pot. A poker hand comprises five cards; in variants where a player has more than five cards available to them, only the best five-card combination counts. There are 10 different kinds of poker hands, such as straight flush and four of a kind. Variants Poker has many variations, all following a similar pattern of play and generally using the same hand ranking hierarchy. There are four main families of variants, largely grouped by the protocol of card-dealing and betting: Straight A complete hand is dealt to each player, and players bet in one round, with raising and re-raising allowed. This is the oldest poker family; the root of the game as now played was a game known as Primero, which evolved into the game three-card brag, a very popular gentleman's game around the time of the American Revolutionary War and still enjoyed in the U.K. today. Straight hands of five cards are sometimes used as a final showdown, but poker is almost always played in a more complex form to allow for additional strategy. Stud poker Cards are dealt in a prearranged combination of face-down and face-up rounds, or streets, with a round of betting following each. This is the next-oldest family; as poker progressed from three to five-card hands, they were often dealt one card at a time, either face-down or face-up, with a betting round between each. The most popular stud variant today, seven-card stud, deals two extra cards to each player (three face-down, four face-up) from which they must make the best possible 5-card hand. Draw poker Five-card draw: A complete hand is dealt to each player, face-down. Then each player must place an ante to the pot. They can then see their cards and bet accordingly. After betting, players can discard up to three cards and take new ones from the top of the deck. Then, another round of betting takes place. Finally, each player must show his or her cards and the player with the best hand wins. Community card poker Also known as "flop poker", community card poker is a variation of stud poker. Players are dealt an incomplete hand of face-down cards, and then a number of face-up community cards are dealt to the centre of the table, each of which can be used by one or more of the players to make a 5-card hand. Texas hold 'em and Omaha are two well-known variants of the community card family. There are several methods for defining the structure of betting during a hand of poker. The three most common structures are known as "fixed-limit", "pot-limit", and "no-limit". In fixed-limit poker, betting and raising must be done by standardised amounts. For instance, if the required bet is X, an initial bettor may only bet X; if a | wishes to raise a bet, they may only raise by X. In pot-limit poker, a player may bet or raise any amount up to the size of the pot. When calculating the maximum raise allowed, all previous bets and calls, including the intending raiser's call, are first added to the pot. The raiser may then raise the previous bet by the full amount of the pot. In no-limit poker, a player may wager their entire betting stack at any point that they are allowed to make a bet. In all games, if a player does not have enough betting chips to fully match a bet, they may go "all-in", allowing them to show down their hand for the amount of chips they have remaining. While typical poker games award the pot to the highest hand as per the standard ranking of poker hands, there are variations where the best hand, and thus the hand awarded the pot, is the lowest-ranked hand instead. In such games the best hand contains the lowest cards rather than the highest cards; some variations may be further complicated by whether or not hands such as flushes and straights are considered in the hand rankings. There are also games where the highest and lowest hands divide the pot between them, known as "high low split" games. Other games that use poker hand rankings may likewise be referred to as poker. Video poker is a single-player video game that functions much like a slot machine; most video poker machines play draw poker, where the player bets, a hand is dealt, and the player can discard and replace cards. Payout is dependent on the hand resulting after the draw and the player's initial bet. Strip poker is a traditional poker variation where players remove clothing when they lose bets. Since it depends only on the basic mechanic of betting in rounds, strip poker can be played with any form of poker; however, it is usually based on simple variants with few betting rounds, like five card draw. Another game with the poker name, but with a vastly different mode of play, is called Acey-Deucey or Red Dog poker. This game is more similar to Blackjack in its layout and betting; each player bets against the house, and then is dealt two cards. For the player to win, the third card dealt (after an opportunity to raise the bet) must have a value in-between the first two. Payout is based on the odds that this is possible, based on the difference in values of the first two cards. Other poker-like games played at casinos against the house include three card poker and pai gow poker. Computer programs A variety of computer poker players have been developed by researchers at the University of Alberta, Carnegie Mellon University, and the University of Auckland amongst others. In a January 2015 article published in Science, a group of researchers mostly from the University of Alberta announced that they "essentially weakly solved" heads-up limit Texas Hold 'em with their development of their Cepheus poker bot. The authors claimed that Cepheus would lose at most 0.001 big blinds per game on average against its worst-case opponent, and the strategy is thus so "close to optimal" that "it can't be beaten with statistical significance within a lifetime of human poker playing".

over the program's execution (see casting). Static versus dynamic typing In static typing, all expressions have their types determined prior to when the program is executed, typically at compile-time. For example, 1 and (2+2) are integer expressions; they cannot be passed to a function that expects a string, or stored in a variable that is defined to hold dates. Statically typed languages can be either manifestly typed or type-inferred. In the first case, the programmer must explicitly write types at certain textual positions (for example, at variable declarations). In the second case, the compiler infers the types of expressions and declarations based on context. Most mainstream statically typed languages, such as C++, C# and Java, are manifestly typed. Complete type inference has traditionally been associated with less mainstream languages, such as Haskell and ML. However, many manifestly typed languages support partial type inference; for example, C++, Java and C# all infer types in certain limited cases. Additionally, some programming languages allow for some types to be automatically converted to other types; for example, an int can be used where the program expects a float. Dynamic typing, also called latent typing, determines the type-safety of operations at run time; in other words, types are associated with run-time values rather than textual expressions. As with type-inferred languages, dynamically typed languages do not require the programmer to write explicit type annotations on expressions. Among other things, this may permit a single variable to refer to values of different types at different points in the program execution. However, type errors cannot be automatically detected until a piece of code is actually executed, potentially making debugging more difficult. Lisp, Smalltalk, Perl, Python, JavaScript, and Ruby are all examples of dynamically typed languages. Weak and strong typing Weak typing allows a value of one type to be treated as another, for example treating a string as a number. This can occasionally be useful, but it can also allow some kinds of program faults to go undetected at compile time and even at run time. Strong typing prevents these program faults. An attempt to perform an operation on the wrong type of value raises an error. Strongly typed languages are often termed type-safe or safe. An alternative definition for "weakly typed" refers to languages, such as Perl and JavaScript, which permit a large number of implicit type conversions. In JavaScript, for example, the expression 2 * x implicitly converts x to a number, and this conversion succeeds even if x is null, undefined, an Array, or a string of letters. Such implicit conversions are often useful, but they can mask programming errors. Strong and static are now generally considered orthogonal concepts, but usage in the literature differs. Some use the term strongly typed to mean strongly, statically typed, or, even more confusingly, to mean simply statically typed. Thus C has been called both strongly typed and weakly, statically typed. It may seem odd to some professional programmers that C could be "weakly, statically typed". However, notice that the use of the generic pointer, the void* pointer, does allow for casting of pointers to other pointers without needing to do an explicit cast. This is extremely similar to somehow casting an array of bytes to any kind of datatype in C without using an explicit cast, such as (int) or (char). Standard library and run-time system Most programming languages have an associated core library (sometimes known as the 'standard library', especially if it is included as part of the published language standard), which is conventionally made available by all implementations of the language. Core libraries typically include definitions for commonly used algorithms, data structures, and mechanisms for input and output. The line between a language and its core library differs from language to language. In some cases, the language designers may treat the library as a separate entity from the language. However, a language's core library is often treated as part of the language by its users, and some language specifications even require that this library be made available in all implementations. Indeed, some languages are designed so that the meanings of certain syntactic constructs cannot even be described without referring to the core library. For example, in Java, a string literal is defined as an instance of the java.lang.String class; similarly, in Smalltalk, an anonymous function expression (a "block") constructs an instance of the library's BlockContext class. Conversely, Scheme contains multiple coherent subsets that suffice to construct the rest of the language as library macros, and so the language designers do not even bother to say which portions of the language must be implemented as language constructs, and which must be implemented as parts of a library. Design and implementation Programming languages share properties with natural languages related to their purpose as vehicles for communication, having a syntactic form separate from its semantics, and showing language families of related languages branching one from another. But as artificial constructs, they also differ in fundamental ways from languages that have evolved through usage. A significant difference is that a programming language can be fully described and studied in its entirety since it has a precise and finite definition. By contrast, natural languages have changing meanings given by their users in different communities. While constructed languages are also artificial languages designed from the ground up with a specific purpose, they lack the precise and complete semantic definition that a programming language has. Many programming languages have been designed from scratch, altered to meet new needs, and combined with other languages. Many have eventually fallen into disuse. Although there have been attempts to design one "universal" programming language that serves all purposes, all of them have failed to be generally accepted as filling this role. The need for diverse programming languages arises from the diversity of contexts in which languages are used: Programs range from tiny scripts written by individual hobbyists to huge systems written by hundreds of programmers. Programmers range in expertise from novices who need simplicity above all else to experts who may be comfortable with considerable complexity. Programs must balance speed, size, and simplicity on systems ranging from microcontrollers to supercomputers. Programs may be written once and not change for generations, or they may undergo continual modification. Programmers may simply differ in their tastes: they may be accustomed to discussing problems and expressing them in a particular language. One common trend in the development of programming languages has been to add more ability to solve problems using a higher level of abstraction. The earliest programming languages were tied very closely to the underlying hardware of the computer. As new programming languages have developed, features have been added that let programmers express ideas that are more remote from simple translation into underlying hardware instructions. Because programmers are less tied to the complexity of the computer, their programs can do more computing with less effort from the programmer. This lets them write more functionality per time unit. Natural language programming has been proposed as a way to eliminate the need for a specialized language for programming. However, this goal remains distant and its benefits are open to debate. Edsger W. Dijkstra took the position that the use of a formal language is essential to prevent the introduction of meaningless constructs, and dismissed natural language programming as "foolish". Alan Perlis was similarly dismissive of the idea. Hybrid approaches have been taken in Structured English and SQL. A language's designers and users must construct a number of artifacts that govern and enable the practice of programming. The most important of these artifacts are the language specification and implementation. Specification The specification of a programming language is an artifact that the language users and the implementors can use to agree upon whether a piece of source code is a valid program in that language, and if so what its behavior shall be. A programming language specification can take several forms, including the following: An explicit definition of the syntax, static semantics, and execution semantics of the language. While syntax is commonly specified using a formal grammar, semantic definitions may be written in natural language (e.g., as in the C language), or a formal semantics (e.g., as in Standard ML and Scheme specifications). A description of the behavior of a translator for the language (e.g., the C++ and Fortran specifications). The syntax and semantics of the language have to be inferred from this description, which may be written in natural or a formal language. A reference or model implementation, sometimes written in the language being specified (e.g., Prolog or ANSI REXX). The syntax and semantics of the language are explicit in the behavior of the reference implementation. Implementation An implementation of a programming language provides a way to write programs in that language and execute them on one or more configurations of hardware and software. There are, broadly, two approaches to programming language implementation: compilation and interpretation. It is generally possible to implement a language using either technique. The output of a compiler may be executed by hardware or a program called an interpreter. In some implementations that make use of the interpreter approach there is no distinct boundary between compiling and interpreting. For instance, some implementations of BASIC compile and then execute the source a line at a time. Programs that are executed directly on the hardware usually run much faster than those that are interpreted in software. One technique for improving the performance of interpreted programs is just-in-time compilation. Here the virtual machine, just before execution, translates the blocks of bytecode which are going to be used to machine code, for direct execution on the hardware. Proprietary languages Although most of the most commonly used programming languages have fully open specifications and implementations, many programming languages exist only as proprietary programming languages with the implementation available only from a single vendor, which may claim that such a proprietary language is their intellectual property. Proprietary programming languages are commonly domain specific languages or internal scripting languages for a single product; some proprietary languages are used only internally within a vendor, while others are available to external users. Some programming languages exist on the border between proprietary and open; for example, Oracle Corporation asserts proprietary rights to some aspects of the Java programming language, and Microsoft's C# programming language, which has open implementations of most parts of the system, also has Common Language Runtime (CLR) as a closed environment. Many proprietary languages are widely used, in spite of their proprietary nature; examples include MATLAB, VBScript, and Wolfram Language. Some languages may make the transition from closed to open; for example, Erlang was originally an Ericsson's internal programming language. Use Thousands of different programming languages have been created, mainly in the computing field. Individual software projects commonly use five programming languages or more. Programming languages differ from most other forms of human expression in that they require a greater degree of precision and completeness. When using a natural language to communicate with other people, human authors and speakers can be ambiguous and make small errors, and still expect their intent to be understood. However, figuratively speaking, computers "do exactly what they are told to do", and cannot "understand" what code the programmer intended to write. The combination of the language definition, a program, and the program's inputs must fully specify the external behavior that occurs when the program is executed, within the domain of control of that program. On the other hand, ideas about an algorithm can be communicated to humans without the precision required for execution by using pseudocode, which interleaves natural language with code written in a programming language. A programming language provides a structured mechanism for defining pieces of data, and the operations or transformations that may be carried out automatically on that data. A programmer uses the abstractions present in the language to represent the concepts involved in a computation. These concepts are represented as a collection of the simplest elements available (called primitives). Programming is the process by which programmers combine these primitives to compose new programs, or adapt existing ones to new uses or a changing environment. Programs for a computer might be executed in a batch process without human interaction, or a user might type commands in an interactive session of an interpreter. In this case the "commands" are simply programs, whose execution is chained together. When a language can run its commands through an interpreter (such as a Unix shell or other command-line interface), without compiling, it is called a scripting language. Measuring language usage Determining which is the most widely used programming language is difficult since the definition of usage varies by context. One language may occupy the greater number of programmer hours, a different one has more lines of code, and a third may consume the most CPU time. Some languages are very popular for particular kinds of applications. For example, COBOL is still strong in the corporate data center, often on large mainframes; Fortran in scientific and engineering applications; Ada in aerospace, transportation, military, real-time and embedded applications; and C in embedded applications and operating systems. Other languages are regularly used to write many different kinds of applications. Various methods of measuring language popularity, each subject to a different bias over what is measured, have been proposed: counting the number of job advertisements that mention the language the number of books sold that teach or describe the language estimates of the number of existing lines of code written in the language which may underestimate languages not often found in public searches counts of language references (i.e., to the name of the language) found using a web search engine. Combining and averaging information from various internet sites, stackify.com reported the ten most popular programming languages as (in descending order by overall popularity): Java, C, C++, Python, C#, JavaScript, VB .NET, R, PHP, and MATLAB. Dialects, flavors and implementations A dialect of a programming language or a data exchange language is a (relatively small) variation or extension of the language that does not change its intrinsic nature. With languages such as Scheme and Forth, standards may be considered insufficient, inadequate or illegitimate by implementors, so often they will deviate from the standard, making a new dialect. In other cases, a dialect is created for use in a domain-specific language, often a subset. In the Lisp world, most languages that use basic S-expression syntax and Lisp-like semantics are considered Lisp dialects, although they vary wildly, as do, say, Racket and Clojure. As it is common for one language to have several dialects, it can become quite difficult for an inexperienced programmer to find the right documentation. The BASIC programming language has many dialects. The explosion of Forth dialects led to the saying "If you've seen one Forth... you've seen one Forth." Taxonomies There is no overarching classification scheme for programming languages. A given programming language does not usually have a single ancestor language. Languages commonly arise by combining the elements of several predecessor languages with new ideas in circulation at the time. Ideas that originate in one language will diffuse throughout a family of related languages, and then leap suddenly across familial gaps to appear in an entirely different family. The task is further complicated by the fact that languages can be classified along multiple axes. For example, Java is both an object-oriented language (because it encourages object-oriented organization) and a concurrent language (because it contains built-in constructs for running multiple threads in parallel). Python is an | alter the behavior of the parser make syntax analysis an undecidable problem, and generally blur the distinction between parsing and execution. In contrast to Lisp's macro system and Perl's BEGIN blocks, which may contain general computations, C macros are merely string replacements and do not require code execution. Semantics The term semantics refers to the meaning of languages, as opposed to their form (syntax). Static semantics The static semantics defines restrictions on the structure of valid texts that are hard or impossible to express in standard syntactic formalisms. For compiled languages, static semantics essentially include those semantic rules that can be checked at compile time. Examples include checking that every identifier is declared before it is used (in languages that require such declarations) or that the labels on the arms of a case statement are distinct. Many important restrictions of this type, like checking that identifiers are used in the appropriate context (e.g. not adding an integer to a function name), or that subroutine calls have the appropriate number and type of arguments, can be enforced by defining them as rules in a logic called a type system. Other forms of static analyses like data flow analysis may also be part of static semantics. Newer programming languages like Java and C# have definite assignment analysis, a form of data flow analysis, as part of their static semantics. Dynamic semantics Once data has been specified, the machine must be instructed to perform operations on the data. For example, the semantics may define the strategy by which expressions are evaluated to values, or the manner in which control structures conditionally execute statements. The dynamic semantics (also known as execution semantics) of a language defines how and when the various constructs of a language should produce a program behavior. There are many ways of defining execution semantics. Natural language is often used to specify the execution semantics of languages commonly used in practice. A significant amount of academic research went into formal semantics of programming languages, which allow execution semantics to be specified in a formal manner. Results from this field of research have seen limited application to programming language design and implementation outside academia. Type system A type system defines how a programming language classifies values and expressions into types, how it can manipulate those types and how they interact. The goal of a type system is to verify and usually enforce a certain level of correctness in programs written in that language by detecting certain incorrect operations. Any decidable type system involves a trade-off: while it rejects many incorrect programs, it can also prohibit some correct, albeit unusual programs. In order to bypass this downside, a number of languages have type loopholes, usually unchecked casts that may be used by the programmer to explicitly allow a normally disallowed operation between different types. In most typed languages, the type system is used only to type check programs, but a number of languages, usually functional ones, infer types, relieving the programmer from the need to write type annotations. The formal design and study of type systems is known as type theory. Typed versus untyped languages A language is typed if the specification of every operation defines types of data to which the operation is applicable. For example, the data represented by "this text between the quotes" is a string, and in many programming languages dividing a number by a string has no meaning and will not be executed. The invalid operation may be detected when the program is compiled ("static" type checking) and will be rejected by the compiler with a compilation error message, or it may be detected while the program is running ("dynamic" type checking), resulting in a run-time exception. Many languages allow a function called an exception handler to handle this exception and, for example, always return "-1" as the result. A special case of typed languages are the single-typed languages. These are often scripting or markup languages, such as REXX or SGML, and have only one data type–—most commonly character strings which are used for both symbolic and numeric data. In contrast, an untyped language, such as most assembly languages, allows any operation to be performed on any data, generally sequences of bits of various lengths. High-level untyped languages include BCPL, Tcl, and some varieties of Forth. In practice, while few languages are considered typed from the type theory (verifying or rejecting all operations), most modern languages offer a degree of typing. Many production languages provide means to bypass or subvert the type system, trading type-safety for finer control over the program's execution (see casting). Static versus dynamic typing In static typing, all expressions have their types determined prior to when the program is executed, typically at compile-time. For example, 1 and (2+2) are integer expressions; they cannot be passed to a function that expects a string, or stored in a variable that is defined to hold dates. Statically typed languages can be either manifestly typed or type-inferred. In the first case, the programmer must explicitly write types at certain textual positions (for example, at variable declarations).

planes, hardwood products, casual clothing, shoes and cosmetics. Germany is by far the biggest importer of Poland's exports as of 2013. In the agricultural sector, the biggest money-makers abroad include smoked and fresh fish, fine chocolate, and dairy products, meats and specialty breads, with the exchange rate conducive to export growth. Food exports amounted to 62 billion złoty in 2011, increasing by 17% from 2010. Most Polish exports to the U.S. receive tariff benefits under the Generalized System of Preferences (GSP) program. Poland ranks in the top 20 in the world both in terms of exports and imports, recording a clear trade surplus. Poland is less dependent on external trade than most other Central and Eastern European countries, but its volume of trade with Europe is still substantial. In 2011 the volume of trade (exports plus imports) with the Euro area as share of GDP was 40%, a doubling from the mid 1990s. 30% of Poland's exports are to Germany and another 30% to the rest of Europe. There has been substantial increase in Poland's exports to Russia. However, in August 2014, exports of fruits and vegetables to Russia fell dramatically following its politically motivated ban by Moscow. Foreign direct investment (FDI) was at 40% of GDP in 2010, a doubling over the level in 2000. Most FDI into Poland comes from France, Germany and the Netherlands. Polish firms in turn have foreign investments primarily in Italy and Luxembourg. Most of the internal FDI is in manufacturing, which makes it susceptible to economic fluctuations in the source countries. The UAE has become Poland's largest trading partner in the Arab world, said Roman Chalaczkiewicz, Polish Ambassador to the UAE, speaking to Gulf News. The government offers investors various forms of state aid, such as CIT tax at the level of 19% and investment incentives in 14 Special Economic Zones (among others: income tax exemption, real estate tax exemption, competitive land prices), several industrial and technology parks, the possibility to benefit from the EU structural funds, brownfield and greenfield locations. According to the National Bank of Poland (NBP), the level of FDI inflow into Poland in 2006 amounted to €13.9 billion. According to an Ernst & Young report, Poland ranks 7th in the world in terms of investment attractiveness. However, Ernst & Young's 2010 European attractiveness survey reported that Poland saw a 52% decrease in FDI job creation and a 42% decrease in number of FDI projects since 2008. According to the OECD (www.oecd.org) report, in 2004 Poles were one of the hardest-working nations in Europe. 2010 the World Economic Forum ranked Poland near the bottom of OECD countries in terms of the clarity, efficiency and neutrality of the legal framework used by firms to settle disputes. Sectors Production industries Before World War II, Poland's industrial base was concentrated in the coal, textile, chemical, machinery, iron, and steel sectors. Today it extends to fertilizers, petrochemicals, machine tools, electrical machinery, electronics, car manufacture and shipbuilding. Poland's industrial base suffered greatly during World War II, and many resources were directed toward reconstruction. The socialist economic system imposed in the late 1940s created large and unwieldy economic structures operated under a tight central command. In part because of this systemic rigidity, the economy performed poorly even in comparison with other economies in Central Europe. In 1990, the Tadeusz Mazowiecki government began a comprehensive reform programme to replace the centralised command economy with a market-oriented system. While the results overall have been impressive, many large state-owned industrial enterprises, particularly the rail, mining, steel, and defence sectors, have remained resistant to change and the downsizing required to survive in a market-based economy. Energy Pharmaceutics The total value of the Polish pharmacy market in 2008 was PLN 24.1bn, 11.5% more than in 2007. The non-prescription medicines market, which accounts for about one-third of the total market value, was worth PLN 7.5bn in 2008. This value includes drugs and non-drugs such as dietary supplements, cosmetics, dressings, dental materials, diagnostic tests and medical devices. The prescription medicines market was worth PLN 15.8bn. Mining In 2019, the country was the 3rd largest world producer of rhenium; 5th largest producer of silver in the world; the 12th largest producer of copper; the world's 14th largest producer of sulfur; in addition to being the world's 14th largest producer of salt. Agriculture Agriculture employs 12.7% of the workforce but contributes 3.8% to the gross domestic product (GDP), reflecting relatively low productivity. Unlike the industrial sector, Poland's agricultural sector remained largely in private hands during the decades of real socialist [sic] rule. Most of the former state farms are now leased to farmer tenants. Lack of credit is hampering efforts to sell former state farmland. Currently, Poland's 2 million private farms occupy 90% of all farmland and account for roughly the same percentage of total agricultural production. Farms are small—8 hectares on average—and often fragmented. Farms with an area exceeding 15 ha accounted for 9% of the total number of farms but cover 45% of total agricultural area. Over half of all farm households in Poland produce only for their own needs with little, if any, commercial sales. Poland is a net exporter of processed fruit and vegetables, meat, and dairy products. Processors often rely on imports to supplement domestic supplies of wheat, feed grains, vegetable oil, and protein meals, which are generally insufficient to meet domestic demand. However, Poland is the leading EU producer of potatoes and rye and is one of the world's largest producers of sugar beets and triticale. Poland also is a significant producer of rapeseed, grains, hogs, and cattle. Poland is the sixth-largest producer and exporter of apples in the entire world. Tourism Poland, especially after joining the European Union in 2004, became a place frequently visited by tourists. Most tourist attractions in Poland are connected with natural environment, historic sites and cultural events. They draw millions of tourists every year from all around the world. According to Tourist Institute's data, Poland was visited by 15.7 million tourists in 2006, and by 15 million tourists in 2007, out of the total number of 66.2 million foreign visitors. In 2016 the number of arrivals to Poland amounted to 80.5 million. 17.5 million of this number are arrivals considered for tourism purposes (with at least one night's stay), making it the 16th most visited country in the world. The most popular cities are Kraków, Warsaw, Gdańsk, Wrocław, Łódź, Poznań, Szczecin, Lublin, Toruń, Sopot, Zakopane and the Wieliczka Salt Mine. The best recreational destinations include Poland's Masurian Lake District, Baltic Sea coast, Tatra Mountains (the highest mountain range of Carpathians), Sudetes and Białowieża Forest. Poland's main tourist offers consist of sightseeing within cities and out-of-town historical monuments, business trips, qualified tourism, agrotourism, mountain hiking (trekking) and climbing among others. Financial sector The Polish banking sector is regulated by the Polish Financial Supervision Authority (PFSA). While transforming the country to a market-oriented economy during 1992–97, the government privatized some banks, recapitalized the rest and introduced legal reforms that made the sector competitive. These reforms, and the health and relative stability of the sector, attracted a number of strategic foreign investors. At the beginning of 2009, Poland's banking sector had 51 domestic banks, a network of 578 cooperative banks and 18 branches of foreign-owned banks. In addition, foreign investors had controlling stakes in nearly 40 commercial banks, which made up 68% of the banking capital. Banks in Poland reacted to the financial crisis of 2009 by restraining lending, raising interest rates, and strengthening balance sheets. Subsequently, the sector started lending again, with an increase of more than 4% expected in 2011. Venture capital The segment of the private equity market that finances early-stage high-risk companies, with the potential for fast growth, 130 active firms in Poland (as of March 2019). Between 2009 and 2019, these entities have invested locally in over 750 companies, an average of 9 companies per portfolio. Since 2016, new legal institutions have been established for entities implementing investments in enterprises in the seed or startup phase. In 2018, venture capital funds invested in Polish startups (0.033% of GDP). As of March 2019, total assets managed by VC companies operating in Poland are estimated at . The total value of investments of the Polish VC market is worth . Transportation Poland is served by an extensive network of railways. In most cities, the main railway station is located near a city centre and is well connected to the local transportation system. The infrastructure is operated by Polish State Railways, part of state-run PKP Group. The rail network is very dense in western and northern Poland, while the eastern part of the country is less developed. The capital city, Warsaw, has the country's only rapid transit system: the Warsaw Metro. The most important airport in Poland is Warsaw 'Frederic Chopin' International Airport. Warsaw's airport is the main international hub for LOT Polish Airlines. In addition to Warsaw Chopin, Wrocław, Gdańsk, Katowice, Kraków and Poznań all have international airports. In preparation for the Euro 2012 football championships jointly hosted by Poland and Ukraine, a number of airports around the country were renovated and redeveloped. This included the building of new terminals with an increased number of jetways and stands at both Copernicus Airport in Wrocław and Lech Wałęsa Airport in Gdańsk. Poland has 412,264 km (256,170 mi) of public roads overall. Polish public roads are grouped into categories related to administrative division, which include National roads, Voivodeship roads, Powiat roads and Gmina roads. Motorways and expressways are part of the national road network. As of 10 January 2020, there are 4000 km of motorways and expressways in use.

GDP growth in Poland Recent GDP growth (comparing to the same quarter of previous year): Location Poland has a very good location | As early as 1996, 70% of its trade was with EU members. Neighboring Germany is Poland's main trading partner today. Poland joined the European Union in May 2004. Before that, it fostered regional integration and trade through the Central European Free Trade Agreement (CEFTA), which included Hungary, the Czech Republic, Slovakia and Slovenia. Poland is a founding member of the World Trade Organization. As a member of the European Union, it applies the common external tariff to goods from other countries including the United States. Poland's major imports are capital goods needed for industrial retooling and for manufacturing inputs. The country's exports also include machinery but are highly diversified. The most successful exports are furniture, foods, motor boats, light planes, hardwood products, casual clothing, shoes and cosmetics. Germany is by far the biggest importer of Poland's exports as of 2013. In the agricultural sector, the biggest money-makers abroad include smoked and fresh fish, fine chocolate, and dairy products, meats and specialty breads, with the exchange rate conducive to export growth. Food exports amounted to 62 billion złoty in 2011, increasing by 17% from 2010. Most Polish exports to the U.S. receive tariff benefits under the Generalized System of Preferences (GSP) program. Poland ranks in the top 20 in the world both in terms of exports and imports, recording a clear trade surplus. Poland is less dependent on external trade than most other Central and Eastern European countries, but its volume of trade with Europe is still substantial. In 2011 the volume of trade (exports plus imports) with the Euro area as share of GDP was 40%, a doubling from the mid 1990s. 30% of Poland's exports are to Germany and another 30% to the rest of Europe. There has been substantial increase in Poland's exports to Russia. However, in August 2014, exports of fruits and vegetables to Russia fell dramatically following its politically motivated ban by Moscow. Foreign direct investment (FDI) was at 40% of GDP in 2010, a doubling over the level in 2000. Most FDI into Poland comes from France, Germany and the Netherlands. Polish firms in turn have foreign investments primarily in Italy and Luxembourg. Most of the internal FDI is in manufacturing, which makes it susceptible to economic fluctuations in the source countries. The UAE has become Poland's largest trading partner in the Arab world, said Roman Chalaczkiewicz, Polish Ambassador to the UAE, speaking to Gulf News. The government offers investors various forms of state aid, such as CIT tax at the level of 19% and investment incentives in 14 Special Economic Zones (among others: income tax exemption, real estate tax exemption, competitive land prices), several industrial and technology parks, the possibility to benefit from the EU structural funds, brownfield and greenfield locations. According to the National Bank of Poland (NBP), the level of FDI inflow into Poland in 2006 amounted to €13.9 billion. According to an Ernst & Young report, Poland ranks 7th in the world in terms of investment attractiveness. However, Ernst & Young's 2010 European attractiveness survey reported that Poland saw a 52% decrease in FDI job creation and a 42% decrease in number of FDI projects since 2008. According to the OECD (www.oecd.org) report, in 2004 Poles were one of the hardest-working nations in Europe. 2010 the World Economic Forum ranked Poland near the bottom of OECD countries in terms of the clarity, efficiency and neutrality of the legal framework used by firms to settle disputes. Sectors Production industries Before World War II, Poland's industrial base was concentrated in the coal, textile, chemical, machinery, iron, and steel sectors. Today it extends to fertilizers, petrochemicals, machine tools, electrical machinery, electronics, car manufacture and shipbuilding. Poland's industrial base suffered greatly during World War II, and many resources were directed toward reconstruction. The socialist economic system imposed in the late 1940s created large and unwieldy economic structures operated under a tight central command. In part because of this systemic rigidity, the economy performed poorly even in comparison with other economies in Central Europe. In 1990, the Tadeusz Mazowiecki government began a comprehensive reform programme to replace the centralised command economy with a market-oriented system. While the results overall have been impressive, many large state-owned industrial enterprises, particularly the rail, mining, steel, and defence sectors, have remained resistant to change and the downsizing required to survive in a market-based economy. Energy Pharmaceutics The total value of the Polish pharmacy market in 2008 was PLN 24.1bn, 11.5% more than in 2007. The non-prescription medicines market, which accounts for about one-third of the total market value, was worth PLN 7.5bn in 2008. This value includes drugs and non-drugs such as dietary supplements, cosmetics, dressings, dental materials, diagnostic tests and medical devices. The prescription medicines market was worth PLN 15.8bn. Mining In 2019, the country was the 3rd largest world producer of rhenium; 5th largest producer of silver in the world; the 12th largest producer of copper; the world's 14th largest producer of sulfur; in addition to being the world's 14th largest producer of salt. Agriculture Agriculture employs 12.7% of the workforce but contributes 3.8% to the gross domestic product (GDP), reflecting relatively low productivity. Unlike the industrial sector, Poland's agricultural sector remained largely in private hands during the decades of real socialist [sic] rule. Most of the former state farms are now leased to farmer tenants. Lack of credit is hampering efforts to sell former state farmland. Currently, Poland's 2 million private farms occupy 90% of all farmland and account for roughly the same percentage of total agricultural production. Farms are small—8 hectares on average—and often fragmented. Farms with an area exceeding 15 ha accounted for 9% of the total number of farms but cover 45% of total agricultural area. Over half of all farm households in Poland produce only for their own needs with little, if any, commercial sales. Poland is a net exporter of processed fruit and vegetables, meat, and dairy products. Processors often rely on imports to supplement domestic supplies of wheat, feed grains, vegetable oil, and protein meals, which are generally insufficient to meet domestic demand. However, Poland is the leading EU producer of potatoes and rye and is one of the world's largest producers of sugar beets and triticale. Poland also is a significant producer of rapeseed, grains, hogs, and cattle. Poland is the sixth-largest producer and exporter of apples in the entire world. Tourism Poland, especially after joining the European Union in 2004, became a place frequently visited by tourists. Most tourist attractions in Poland are connected with natural environment, historic sites and cultural events. They draw millions of tourists every year from all around the world. According to Tourist Institute's data, Poland was visited by 15.7 million tourists in 2006, and by 15 million tourists in 2007, out of the total number of 66.2 million foreign visitors. In 2016 the number of arrivals to Poland amounted to 80.5 million. 17.5 million of this number are arrivals considered for tourism purposes (with at least one night's stay), making it the 16th most visited country in the world. The most popular cities are Kraków, Warsaw, Gdańsk, Wrocław, Łódź, Poznań, Szczecin, Lublin, Toruń, Sopot, Zakopane and the Wieliczka Salt Mine. The best recreational destinations include Poland's Masurian Lake District, Baltic Sea coast, Tatra Mountains (the highest mountain range of Carpathians), Sudetes and Białowieża Forest. Poland's main tourist offers consist of sightseeing within cities and out-of-town historical monuments, business trips, qualified tourism, agrotourism, mountain hiking (trekking) and climbing among others. Financial sector The Polish banking sector is regulated by the Polish Financial Supervision Authority (PFSA). While transforming the country to a market-oriented economy during 1992–97, the government privatized some banks, recapitalized the rest and introduced legal reforms that made the sector competitive. These reforms, and the health and relative stability of the sector, attracted a number of strategic foreign investors. At the beginning of 2009, Poland's banking sector had 51 domestic banks, a network of 578 cooperative banks and 18 branches of foreign-owned banks. In addition, foreign investors had controlling stakes in nearly 40 commercial banks, which made up 68% of the banking capital. Banks in Poland reacted to the financial crisis of 2009 by restraining lending, raising interest rates, and strengthening balance sheets. Subsequently, the sector started lending again, with an increase of more than 4% expected in 2011. Venture capital The segment of the private equity market that finances early-stage high-risk companies, with the potential for fast growth, 130 active firms in Poland (as of March 2019). Between 2009 and 2019, these entities have invested locally in over 750 companies, an average of 9 companies per portfolio. Since 2016, new legal institutions have been established for entities implementing investments in enterprises in the seed or startup phase. In 2018, venture capital funds invested in Polish startups (0.033% of GDP). As of March 2019, total assets managed by VC companies operating in Poland are estimated at . The total value of investments of the Polish VC market is worth . Transportation Poland is served by an extensive network of railways. In most cities, the main railway station is located near a city centre and is well connected to the local transportation system. The infrastructure is operated by Polish State Railways, part of state-run PKP Group. The rail network is very dense in western and northern Poland, while the eastern part of the country is less developed.

From the communist era Poland inherited an underdeveloped and outmoded system of telephones, with some areas (e.g. in the extreme South East) being served by manual exchanges. In December 2005 the last analog exchange was shut down. All telephone lines are now served by modern fully computerized exchanges (Siemens EWSD, Alcatel S12, Lucent 5ESS, Alcatel E10).

Poland has actively pursued good relations with all its neighboring countries, signing friendship treaties replacing links severed by the collapse of the Warsaw Pact. The Poles have forged special relationships with Lithuania and particularly Ukraine in an effort to firmly anchor these states to the West. Due to its tragic historical experience with aggression of powerful neighbors (e.g., Partitions of Poland, Second World War), Polish foreign policy pursues close cooperation with a strong partner, one apt enough to give strong military support in times of critical situations. This creates the background of Poland's tight relations with the USA and their sensitivity in relations towards its partner within the European Union, Germany. At the same time, the equally burdened attitude towards Russia results in very tense diplomatic relations, which have been constantly worsening since Vladimir Putin's rise to power.

with the aim of undermining it. Polish print media and radio outlets are mainly private and diversified in terms of ownership, however foreign owners control around three-quarters of the Polish media market. The main domestic competitor is Agora, which owns Gazeta Wyborcza and a number of magazines, radio stations, internet platforms, a publishing house and additional ventures. Foreign ownership is very strong also in the regional media which are largely owned by the German Polska Press. To counter foreign ownership in Polish media, in 2021, the PiS government submitted a bill that would ban non-European-Union citizens and companies from possessing a controlling stake in Polish media outlets. In August 11 2021, The bill Lex TVN which forbids companies except those from the European Economic Area from holding more than a 49% stake in Polish radio and television stations passed the Sejm. Media freedom and pluralism In recent years, according to Reporters Without Borders, in particular since the PiS went to power in 2015, media freedom in Poland has been significantly deteriorating. Just weeks after winning the 2015 parliamentary elections, the PiS passed a media law which gave the government direct control over public broadcasting. It also replaced journalists working in the public radio and TV stations and tried to throttle several independent print media outlets, such as Gazeta Wyborcza, Polityka and Newsweek Polska by restricting public advertising. According to Freedom House, this effort is part of a broader attempt to weaken checks and balances, silence independent voices and control the public sphere. PiS's control on the executive branch and the executive can undermine the independence of the judiciary and its aggressive attitude towards the Constitutional Tribunal has prompted accusations that it is undermining the rule of law in Poland. In January 2016, the European Commission launched a procedure in order to impose the respect of the rule of law in the country. Reporters Without Borders in its 2019 assessment of Poland stated that the public media "have been transformed into government propaganda mouthpieces." Poland is rated "Partly Free" in Freedom House's 2017 "Freedom of the Press" report. It is ranked 62 out of 180 countries in the 2020 World Press Freedom index by Reporters Without Borders, down from 18th in 2015. The case of the public television and radio broadcasters After winning parliamentary elections in October 2015, the PiS party replaced the management positions at the public television and radio broadcasters. This effort was not limited to public broadcasters since the party leadership tried to control also private media outlets for instance by advancing a proposal to restrict reporters’ access to the parliament. In December 2015 the so-called "small media law" prepared by PiS was sent to the Polish parliament. The proposal, which was conceived as a temporary measure before the adoption of a more comprehensive media law, provided for the termination of the mandates of the current members of the national television and radio broadcasters’ management and supervisory boards and their replacement through the direct appointment by the treasury minister. The law created great turmoil in public media: the directors of several public channels left their position in protest. Public protests occurred across Poland as well as abroad in the environment connected the community of Poles living abroad. The staffing changes were not limited to the managing positions. According to the Association of Journalists, 225 journalists left the public media during 2016, due to either layoffs or resignations. The new law and its effects were widely criticized also abroad: the European Federation of Journalists, the European Broadcasting Union, the Association of European Journalists, Reporters Without Borders, the Committee to Protect Journalists and Index on Censorship denounced this decision. In January 2016, the European Commission discussed the "small media law" in the frame of its assessment of the situation in Poland under the Rule of Law Framework. In December 2016, the Constitutional Tribunal declared parts of the "small media law" unconstitutional, calling for the need to constitutional rules on the KRRiT which should have played a decisive role in appointing its management and supervisory boards. In the first months of 2016 the PiS's government worked on a "big media law", a more comprehensive reform of the media system. In April 2016, a draft Law on National Media was presented to the Parliament. The draft wanted to transform the public radio and television broadcasters into "national media", thus shifting away from the model of editorially independent public service. The bill obliged the public media to disseminate the views of the prime minister, the president, and the speakers of the parliament and stated that the public media should preserve national traditions, patriotic and Christian values and strengthen the national community. The Council of Europe criticized the draft, describing it a move towards a "State broadcasters". The law was not adopted: the government decided to pursue a less ambitious approach and proposed the Parliament a "bridge law" to go into force at the expiration of the "small media law". The "bridge law" was approved in June 2016: the law stated that a newly established National Media Council have to be responsible for the appointment of the management and supervisory boards of the public media. The arrangement established by the law effectively guarantees the rule party a key role in appointing the members of the national Media Council. The law also does not forbid the new council's members from belonging to political party.

It also replaced journalists working in the public radio and TV stations and tried to throttle several independent print media outlets, such as Gazeta Wyborcza, Polityka and Newsweek Polska by restricting public advertising. According to Freedom House, this effort is part of a broader attempt to weaken checks and balances, silence independent voices and control the public sphere. PiS's control on the executive branch and the executive can undermine the independence of the judiciary and its aggressive attitude towards the Constitutional Tribunal has prompted accusations that it is undermining the rule of law in Poland.

of Alentejo. Mount Pico is recognized as receiving the largest annual rainfall (over per year) in Portugal, according to Instituto Português do Mar e da Atmosfera. In some areas, such as the Guadiana basin, annual diurnal average temperatures can be as high as , and summer's highest temperatures are routinely over . The record high of was recorded in Amareleja, although this might not be the hottest spot in summer, according to satellite readings. Snowfalls occur regularly in the winter in the interior North and Centre of the country in districts such as Guarda, Bragança, Viseu and Vila Real, particularly on the mountains. In winter, temperatures may drop below , particularly in Serra da Estrela, Serra do Gerês, Serra do Marão and Serra de Montesinho. In these places snow can fall any time from October to May. In the South of the country snowfalls are rare but still occur in the highest elevations. While the official absolute minimum by IPMA is in Penhas da Saúde and Miranda do Douro, lower temperatures have been recorded, such as by Bragança Polytechnic Institute in the outskirts of the city in 1983, and below in Serra da Estrela. Continental Portugal has around 2300 to 3200 hours of sunshine a year, an average of 4–6 h in winter and 10–12 h in the summer, with higher values in the south-east, south-west and the Algarve coast and lower in the north-west. Insolation values are lower in the archipelagos, with around 1600 h in the humid Flores Island and around 2300 h in the island of Madeira and Porto Santo. Insolation in the Selvagens is thought to be higher due to weaker orographic lift and their relative proximity to the Sahara Desert. Portugal's central west and southwest coasts have an extreme ocean seasonal lag, sea temperatures are warmer in October than in July and are their coldest in March. The average sea surface temperature on the west coast of mainland Portugal varies from in January−March to in August−October while on the south coast it ranges from in January−March and rises in the summer to about , occasionally reaching . In the Azores, around in February−April to in July−September, and in Madeira, around in February−April to in August−October. Both the archipelagos of the Azores and Madeira have a subtropical climate, although variations between islands exist, making weather predictions very difficult (owing to rough topography). The Madeira and Azorean archipelagos have a narrower temperature range, with annual average temperatures exceeding in some parts of the coast (according to the Portuguese Meteorological Institute). Some islands in Azores do have drier months in the summer. Consequently, the islands of the Azores have been identified as having a Mediterranean climate (both Csa and Csb types), while some islands (such as Flores or Corvo) are classified as Humid subtropical (Cfa), transitioning into an Oceanic climate (Cfb) at higher altitudes, according to Köppen-Geiger classification. Porto Santo Island in Madeira has a warm semi-arid climate (BSh). The Savage Islands, which are part of the regional territory of Madeira and a nature reserve are unique in being classified as a desert climate (BWh) with an annual average rainfall of approximately . The sea surface temperature in these islands varies from in winter to in the summer occasionally reaching . Biodiversity Portugal is located on the Mediterranean Basin, the third most diverse hotspot of flora in the world. Due to its geographical and climatic context - between the Mediterranean and the Atlantic - Portugal has a high level of biodiversity on land and at sea. It is home to six terrestrial ecoregions: Azores temperate mixed forests, Cantabrian mixed forests, Madeira evergreen forests, Iberian sclerophyllous and semi-deciduous forests, Northwest Iberian montane forests, and Southwest Iberian Mediterranean sclerophyllous and mixed forests. Over 22% of its land area is included in the Natura 2000 network, including 62 special conservation areas and 88 types of protected landscape natural habitats. Eucalyptus, cork oak and maritime pine together make up 71% of the total forested area of continental Portugal, followed by the holm oak, the stone pine, the other oak trees (Q. robur, Q. faginea and Q. pyrenaica) and the sweet chestnut, respectively. On Madeira, laurisilva (recognized as a World Heritage Site) dominates the landscape, especially on the northern slope. The predominant species in this forest include Laurus novocanariensis, Apollonias barbujana, Ocotea foetens and Persea indica. Before human occupation the Azores were also rich in dense laurisilva forests, today these native forests are undermined by the introduced Pittosporum undulatum and Cryptomeria japonica. There have been several projects aimed to recover the Laurisilva present in the Azores. Remnants of these laurisilva forests are also present in continental Portugal with its few living testimonies Laurus nobilis, Prunus lusitanica, Arbutus unedo, Myrica faya and Rhododendron ponticum. These geographical and climatic conditions facilitate the introduction of exotic species that later turn to be invasive and destructive to the native habitats. More than 20% of the total number of extant species in continental Portugal are exotic. On Madeira, around 36% and on the Azores, around 70% are exotic. Due to this, Portugal was placed 168th globally out of 172 countries on the Forest Landscape Integrity Index in 2019. Portugal is the second country in Europe with the highest number of threatened species (488 as of 2020). Portugal as a whole is an important stopover for migratory bird species: the marshes of the eastern Algarve (Ria Formosa, Castro Marim) and the Lisbon Region (Tagus Estuary, Sado Estuary) hosting various aquatic bird species, the Bonelli's eagle and Egyptian vulture on the valleys of the Douro International, the black stork and griffon vulture on the Tagus International, the seabird sanctuaries of the Savage Islands and Berlengas and the highlands of Madeira and São Miguel all represent the great diversity of wild avian species (around 450 in continental Portugal), not only migratory but also endemic (e.g. trocaz pigeon, Azores bullfinch) or exotic (crested myna, pin-tailed whydah). The large mammalian species of Portugal (the fallow deer, red deer, roe deer, Iberian ibex, wild boar, red fox, Iberian wolf and Iberian lynx) were once widespread throughout the country, but intense hunting, habitat degradation and growing pressure from agriculture and livestock reduced population numbers on a large scale in the 19th and early 20th century, others, such as the Portuguese ibex were even led to extinction. Today, these animals are re-expanding their native range. Smaller mammals include the red squirrel, European badger, Eurasian otter, Egyptian mongoose, Granada hare, European rabbit, common genet, European wildcat, among others. Due to their isolated location, the volcanic islands of the Azores, Madeira and Salvages, part of Macaronesia, have many endemic species that have evolved independently from their European, African and occasionally American relatives. The Portuguese west coast is part of the four major Eastern Boundary Upwelling Systems of the ocean. This seasonal upwelling system typically seen during the summer months brings cooler, nutrient rich water up to the sea surface promoting phytoplankton growth, zooplankton development and the subsequent rich diversity in pelagic fish and other marine invertebrates. This, adding to its large EEZ makes Portugal one of the largest fish consumers in the world per capita. Sardines (Sardina pilchardus) and horse mackerel (Trachurus trachurus) are collected in the thousands every year. while blue whiting, monkfish, Atlantic cod, cephalopods, skates or any other form of seafood are traditionally fished in the local coastal villages. This upwelling also allows Portugal to have kelp forests which are otherwise very uncommon or non-existent on the Mediterranean. 73% of the freshwater fish occurring in the Iberian Peninsula are endemic, the largest out of any region in Europe. Many of these endemic species are concentrated in bodies of water of the central western region (one exclusively endemic), these and other bodies of water throughout the Peninsula are mostly temporary and prone to drought every year, placing most of these species under Threatened status. Around 24 to 28 species of cetacean roam through the Azores, making it one of four places in the world where most species of this infraorder occur. Starting in the mid-19th century and ceasing in 1984, whaling (especially of sperm whale) heavily exploited this diversity. Beginning in the early 90s, whale watching quickly grew to popularity and is now one of the main economic activities in the Portuguese archipelago. Some protected areas in Portugal other than the ones previously mentioned include: the Serras de Aire e Candeeiros with its limestone formations, paleontological history and great diversity in bats and orchids, the Southwest Alentejo and Vicentine Coast Natural Park with its well preserved, wild coastline. the Montesinho Natural Park which hosts some of the only populations of Iberian wolf and a recently sighted Iberian brown bear, considered to be extinct in the country; among others. Government and politics Portugal has been a semi-presidential representative democratic republic since the ratification of the Constitution of 1976, with Lisbon, the nation's largest city, as its capital. The Constitution grants the division or separation of powers among four bodies referred as "organs of Sovereignty": the President of the Republic, the Government, the Assembly of the Republic and the Courts. The President, who is elected to a five-year term, has an executive role: the current President is Marcelo Rebelo de Sousa. The Assembly of the Republic is a single chamber parliament composed of a maximum of 230 deputies elected for a four-year term. The Government is headed by the Prime Minister (currently António Costa) and includes Ministers and Secretaries of State. The Courts are organized into several levels, among the judicial, administrative and fiscal branches. The Supreme Courts are institutions of last resort/appeal. A thirteen-member Constitutional Court oversees the constitutionality of the laws. Portugal operates a multi-party system of competitive legislatures/local administrative governments at the national, regional and local levels. The Assembly of the Republic, Regional Assemblies and local municipalities and parishes, are dominated by two political parties, the Socialist Party and the Social Democratic Party, in addition to the Unitary Democratic Coalition (Portuguese Communist Party and Ecologist Party "The Greens"), the Left Bloc and the Democratic and Social Centre – People's Party, which garner between 5 and 15% of the vote regularly. Presidency of the Republic The Head of State of Portugal is the President of the Republic, elected to a five-year term by direct, universal suffrage. Presidential powers include the appointment of the Prime Minister and the other members of the Government (where the President takes into account the results of legislative elections); dismissing the Prime Minister; dissolving the Assembly of the Republic (to call early elections); vetoing legislation (which may be overridden by the Assembly); and declaring a state of war or siege. The President has also supervisory and reserve powers and is the ex officio Commander-in-Chief of the Armed Forces. The President is advised on issues of importance by the Council of State, which is composed of six senior civilian officers, any former Presidents elected under the 1976 Constitution, five-members chosen by the Assembly, and five selected by the president. Government The Government is headed by the presidentially appointed Prime Minister, also including one or more Deputy Prime Ministers, Ministers, Secretaries of State and Under-Secretaries of State. The Government is both the organ of sovereignty that conducts the general politics of the country and the superior body of the public administration. It has essentially Executive powers, but has also limited legislative powers. The Government can legislate about its own organization, about areas covered by legislative authorizations conceded by the Assembly of the Republic and about the specific regulation of generalist laws issued by the Assembly. The Council of Ministers – under the presidency of the Prime Minister (or the President of Portugal at the latter's request) and the Ministers (may also include one or more Deputy Prime Ministers) – acts as the cabinet. Each government is required to define the broad outline of its policies in a programme, and present it to the Assembly for a mandatory period of debate. The failure of the Assembly to reject the government programme by an absolute majority of deputies confirms the cabinet in office. Parliament The Assembly of the Republic, in Lisbon, is the national parliament of Portugal. It is the main legislative body, although the Government also has limited legislative powers. The Assembly of the Republic is a unicameral body composed of up to 230 deputies. Elected by universal suffrage according to a system of closed party-list proportional representation, deputies serve four-year terms of office, unless the President dissolves the Assembly and calls for new elections. Currently the Government (PS) and the parties supporting it through a confidence-and-supply agreement (BE, PCP, PEV) control parliament with the most seats. The PSD and CDS-PP parties form the opposition to the government alongside PAN, Chega, Iniciativa Liberal and Partido Livre. Foreign relations A member state of the United Nations since 1955, Portugal is also a founding member of NATO (1949), OECD (1961) and EFTA (1960); it left the last in 1986 to join the European Economic Community, which became the European Union in 1993. In 1996, Portugal co-founded the Community of Portuguese Language Countries (CPLP), also known as the Lusophone Commonwealth, an international organization and political association of Lusophone nations across four continents, where Portuguese is an official language. The global headquarters of the CPLP is in Penafiel Palace, in Lisbon. António Guterres, who has served as Prime Minister of Portugal from 1995 to 2002 and UN High Commissioner for Refugees from 2005 to 2015, assumed the post of UN Secretary-General on 1 January 2017; making him the first Secretary-General from Western Europe since Kurt Waldheim of Austria (1972–1981), the first former head of government to become Secretary-General and the first Secretary-General born after the establishment of the United Nations on 26 June 1945. In addition, Portugal was a full member of the Latin Union (1983) and the Organization of Ibero-American States (1949). It has a friendship alliance and dual citizenship treaty with its former colony, Brazil. Portugal and the United Kingdom share the world's oldest active military accord through their Anglo-Portuguese Alliance (Treaty of Windsor), which was signed in 1373. There are two international territorial disputes, both with Spain: Olivenza. Under Portuguese sovereignty since 1297, the municipality of Olivenza was ceded to Spain under the Treaty of Badajoz in 1801, after the War of the Oranges. Portugal claimed it back in 1815 under the Treaty of Vienna. However, since the 19th century, it has been continuously ruled by Spain which considers the territory theirs not only de facto but also de jure. The Ilhas Selvagens (Savage Islands). The archipelago is under Portuguese domination but is geographically closer to the Canary Islands (165 km) than to Madeira (280 km). Found in 1364 by Italian navigators, the islands belonged to private owners until 1971, when the Portuguese government bought them and established a natural reserve area covering the whole archipelago. The islands have been claimed by Spain since 1911 and the dispute has caused some periods of political tension between the two countries. The main problem is not so much their intrinsic value but the fact that they expand the Exclusive Economic Zone of Portugal considerably to the south. Military The armed forces have three branches: Navy, Army and Air Force. They serve primarily as a self-defence force whose mission is to protect the territorial integrity of the country and provide humanitarian assistance and security at home and abroad. , the three branches numbered 39,200 active personnel including 7,500 women. Portuguese military expenditure in 2009 was 5 billion US$, representing 2.1 per cent of GDP. Military conscription was abolished in 2004. The minimum age for voluntary recruitment is 18 years. The Army (21,000 personnel) comprises three brigades and other small units. An infantry brigade (mainly equipped with Pandur II APC), a mechanized brigade (mainly equipped with Leopard 2 A6 tanks and M113 APC) and a Rapid Reaction Brigade (consisting of paratroopers, commandos and rangers). The Navy (10,700 personnel, of which 1,580 are marines), the world's oldest surviving naval force, has five frigates, seven corvettes, two submarines, and 28 patrol and auxiliary vessels. The Air Force (7,500 personnel) has the Lockheed F-16 Fighting Falcon as the main combat aircraft. In addition to the three branches of the armed forces, there is the National Republican Guard, a security force subject to military law and organization (gendarmerie) comprising 25,000 personnel. This force is under the authority of both the Defence and the Interior Ministry. It has provided detachments for participation in international operations in Iraq and East Timor. The United States maintains a military presence with 770 troops in the Lajes Air Base at Terceira Island, in the Azores. The Allied Joint Force Command Lisbon (JFC Lisbon) – one of the three main subdivisions of NATO's Allied Command Operations – it is based in Oeiras, near Lisbon. In the 20th century, Portugal engaged in two major conflicts: World War I and the Portuguese Colonial War (1961–1974). After the end of the Portuguese Empire in 1975, the Portuguese Armed Forces have participated in peacekeeping missions in East Timor, Bosnia, Kosovo, Afghanistan, Somalia, Iraq (Nasiriyah), Lebanon, Mali and Central African Republic. Portugal also conducted several independent unilateral military operations abroad, as were the cases of the interventions of the Portuguese Armed Forces in Angola in 1992 and in Guinea-Bissau in 1998 with the main objectives of protecting and withdrawing of Portuguese and foreign citizens threatened by local civil conflicts. Law The Portuguese legal system is part of the civil law legal system, also called the continental family legal system. The main laws include the Constitution (1976, as amended), the Portuguese Civil Code (1966, as amended) and the Penal Code of Portugal (1982, as amended). Other relevant laws are the Commercial Code (1888, as amended) and the Civil Procedure Code (1961, as amended). The supreme national courts are the Supreme Court of Justice and the Constitutional Court. The Public Ministry, headed by the Attorney General of the Republic, constitutes the independent body of public prosecutors. Portuguese laws were applied in the former colonies and territories and continue to be major influences for those countries. Portugal was the first country in the world to abolish life imprisonment (in 1884) and was one of the first countries to abolish the death penalty. Maximum jail sentences are limited to 25 years. Portugal is also known for having decriminalized the usage of all common drugs in 2001, the first country in the world to do so. Portugal decriminalized possession of effectively all drugs that are still illegal in other developed nations including cannabis, cocaine, heroin, and LSD. While possession is legal, trafficking and possession of more than "10 days worth of personal use" are still punishable by jail time and fines. People caught with small amounts of any drug are given the choice to go to a rehab facility, and may refuse treatment without consequences. Despite criticism from other European nations, who stated Portugal's drug consumption would tremendously increase, overall drug use has declined along with the number of HIV infection cases, which had dropped 50 percent by 2009. Drug use among 16- to 18-year-olds also declined, however the use of marijuana rose only slightly among that age group. LGBTI rights have increased substantially in the past years. On 27 August 2003, Portugal added the anti-discrimination employment law on the basis of sexual orientation. At 24 July 2004, sexual orientation was added to the Constitution as part of the protected from discrimination characteristics. On 31 May 2010, Portugal became the sixth country in Europe and the eighth country in the world to legally recognize same-sex marriage at the national level. The law came into force on 5 June 2010. Same-sex adoption has been allowed since 1 March 2016 as is female same-sex couple access to medically assisted reproduction since 13 May 2016. This bill was adopted by the Parliament and signed by President Marcelo Rebelo de Sousa. As of January 2017 the New Law of Gender Identity, simplified the legal process of gender and name change for transgender people, making it easier for minors to change their sex marker in legal documents. At August 2018, the right to gender identity and gender expression self-determination became protected, intersex minors became protected by law from unnecessary medical procedures "until the minor gender identity manifests" and the right of protection from discrimination on the basis of sex characteristics also became protected by the same law. Law enforcement Portugal's main police organizations are the Guarda Nacional Republicana – GNR (National Republican Guard), a gendarmerie; the Polícia de Segurança Pública – PSP (Public Security Police), a civilian police force who work in urban areas; and the Polícia Judiciária – PJ (Judicial Police), a highly specialized criminal investigation police that is overseen by the Public Ministry. Correctional services Portugal has 49 correctional facilities in total run by the Ministry of Justice. They include 17 central prisons, 4 special prisons, 27 regional prisons, and 1 'Cadeia de Apoio'(Support Detention Centre). , their current prison population is about 11,234 inmates, which comes to about 0.11% of their entire population. Their incarceration rate has been on the rise since 2010, with a 15% increase over the past eight years. Administrative divisions Administratively, Portugal is divided into 308 municipalities (), which after a reform in 2013 are subdivided into 3,092 civil parishes (). Operationally, the municipality and civil parish, along with the national government, are the only legally local administrative units identified by the government of Portugal (for example, cities, towns or villages have no standing in law, although may be used as catchment for the defining services). For statistical purposes the Portuguese government also identifies Nomenclature of Territorial Units for Statistics (NUTS), inter-municipal communities and informally, the district system, used until European integration (and being phased-out by the national government). Continental Portugal is agglomerated into 18 districts, while the archipelagos of the Azores and Madeira are governed as autonomous regions; the largest units, established since 1976, are either mainland Portugal () and the autonomous regions of Portugal (Azores and Madeira). The 18 districts of mainland Portugal are: Aveiro, Beja, Braga, Bragança, Castelo Branco, Coimbra, Évora, Faro, Guarda, Leiria, Lisbon, Portalegre, Porto, Santarém, Setúbal, Viana do Castelo, Vila Real and Viseu – each district takes the name of the district capital. Within the European Union NUTS system, Portugal is divided into seven regions: the Azores, Alentejo, Algarve, Centro, Lisboa, Madeira and Norte, and with the exception of the Azores and Madeira, NUTS areas are subdivided into 28 subregions. Government finance The Portuguese government is heavily indebted, and received a 78-billion-euro bailout from the European Union and the International Monetary Fund in May 2011. The ratio of Portugal's debt to its overall economy, was 107 per cent when it received the bailout. As part of the deal, the country agreed to cut its budget deficit from 9.8 per cent of GDP in 2010 to 5.9 per cent in 2011, 4.5 per cent in 2012 and 3 per cent in 2013. After the bailout was announced, the Portuguese government headed by Pedro Passos Coelho managed to implement measures with the intention of improving the state's financial situation, including tax hikes, a freeze of civil service-related lower-wages and cuts of higher-wages by 14.3%, on top of the government's spending cuts. The Portuguese government also agreed to eliminate its golden share in Portugal Telecom which gave it veto power over vital decisions. In 2012, all public servants had already seen an average wage cut of 20% relative to their 2010 baseline, with cuts reaching 25% for those earning more than 1,500 euro per month. The IMF, the European Commission (EC) and the European Central Bank (ECB) said in September 2012 that Portugal's debt would peak at 124 per cent of gross domestic product in 2014. The IMF previously said in July 2012 that Portugal's debt would peak at about 118.5 per cent of GDP in 2013. In September 2013, the Portuguese Government reviewed again the public debt of Portugal for 2013 to 127.8 per cent, after a peak of 130.9 per cent in that month. A report released in January 2011 by the Diário de Notícias and published in Portugal by Gradiva, had demonstrated that in the period between the Carnation Revolution in 1974 and 2010, the democratic Portuguese Republic governments encouraged over-expenditure and investment bubbles through unclear Public–private partnerships and funding of numerous ineffective and unnecessary external consultancy and advisory of committees and firms. This allowed considerable slippage in state-managed public works and inflated top management and head officer bonuses and wages. Persistent and lasting recruitment policies boosted the number of redundant public servants. Risky credit, public debt creation, and European structural and cohesion funds were mismanaged across almost four decades. Two Portuguese banks, Banco Português de Negócios (BPN) and Banco Privado Português (BPP), had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications – Portugal's then President, Cavaco Silva and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. On grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general. Economy Portugal is a developed and a high-income country, with a GDP per capita of 77% of the EU28 average in 2017 (increasing from 75% in 2012) and a HDI of 0.850 (the 40th highest) in 2018. By the end of 2018, Portugal's GDP (PPP) was $32,554 per capita, according to OECD's report. The national currency of Portugal is the euro (€), which replaced the Portuguese Escudo, and the country was one of the original member states of the eurozone. Portugal's central bank is the Banco de Portugal, an integral part of the European System of Central Banks. Most industries, businesses and financial institutions are concentrated in the Lisbon and Porto metropolitan areas – the Setúbal, Aveiro, Braga, Coimbra, Leiria and Faro districts are the biggest economic centres outside these two main areas. According to World Travel Awards, Portugal was Europe's Leading Golf Destination in 2012 and 2013. Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth. After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013. Since the 1990s, Portugal's public consumption-based economic development model has been slowly changing to a system that is focused on exports, private investment and the development of the high-tech sector. Consequently, business services have overtaken more traditional industries such as textiles, clothing, footwear and cork (Portugal is the world's leading cork producer), wood products and beverages. In the second decade of the 21st century, the Portuguese economy suffered its most severe recession since the 1970s, resulting in the country having to be bailed out by the European Commission, European Central Bank and International Monetary Fund (IMF). The bailout, agreed to in 2011, required Portugal to enter into a range of austerity measures in exchange for funding support of €78,000,000,000. In May 2014, the country exited the bailout but reaffirmed its commitment to maintaining its reformist momentum. At the time of exiting the bailout, the economy had contracted by 0.7% in the first quarter of 2014; however, unemployment, while still high, had fallen to 15.3%. The average salary in Portugal is €910 per month, excluding self-employed individuals and the minimum wage, which is regulated by law, is €705 per month (paid 14 times per annum) as of 2022. The Global Competitiveness Report for 2019, published by the World Economic Forum, placed Portugal on the 34th position on the economic index. The Economist Intelligence Unit's quality of life index placed Portugal as the country with the 19th-best quality of life in the world for 2005, ahead of other economically and technologically advanced countries like France, Germany, the United Kingdom and South Korea, but 9 places behind its sole neighbour, Spain. This is despite the fact that Portugal remains as one of the countries with the lowest per capita GDP in Western Europe. Major state-owned companies include: Águas de Portugal (water), Caixa Geral de Depósitos (banking), Comboios de Portugal (railways), Companhia das Lezírias (agriculture) and RTP (media). Some former state-owned entities are managed by state-run holding company Parpública, which is a shareholder of several public and private companies. Among former state-owned companies recently privatized are: CTT (postal service) and ANA (airports). Companies listed on Euronext Lisbon stock exchange like EDP, Galp, Jerónimo Martins, Mota-Engil, Novabase, Semapa, Portucel Soporcel, Portugal Telecom and Sonae, are amongst the largest corporations of Portugal by number of employees, net income or international market share. The Euronext Lisbon is the major stock exchange of Portugal and is part of the NYSE Euronext, the first global stock exchange. The PSI-20 is Portugal's most selective and widely known stock index. The International Monetary Fund issued an update report on the economy of Portugal in late-June 2017 with a strong near-term outlook and an increase in investments and exports over previous years. Because of a surplus in 2016, the country was no longer bound by the Excessive Deficit Procedure which had been implemented during an earlier financial crisis. The banking system was more stable, although there were still non-performing loans and corporate debt. The IMF recommended working on solving these problems for Portugal to be able to attract more private investment. "Sustained strong growth, together with continued public debt reduction, would reduce vulnerabilities arising from high indebtedness, particularly when monetary accommodation is reduced." The OECD economic reports since 2018 show recovery, albeit slow; and Portugal's growth prospects continue positive for 2020. Primary sector Agriculture in Portugal is based on small to medium-sized family-owned dispersed units. However, the sector also includes larger scale intensive farming export-oriented agrobusinesses backed by companies (like Grupo RAR's Vitacress, Sovena, Lactogal, Vale da Rosa, Companhia das Lezírias and Valouro). The country produces a wide variety of crops and livestock products, including: tomatoes, citrus, green vegetables, rice, wheat, barley, maize, olives, oilseeds, nuts, cherries, bilberry, table grapes, edible mushrooms, dairy products, poultry and beef. According to FAO, Portugal is the top producer of cork and carob in the world, accounting to about 50% and 30% of world production respectively. It is also the third largest exporter of chestnut and the third largest European producer of pulp. Portugal is among the top ten largest olive oil producers in the world and is the fourth biggest exporter. The country is also one of the world's largest exporters of wine, being reputed for its fine wines. Forestry has also played an important economic role among the rural communities and industry (namely paper industry that includes Portucel Soporcel Group, engineered wood that includes Sonae Indústria, and furniture that includes several manufacturing plants in and around Paços de Ferreira, the core of Portugal's major industrial operations of IKEA). In 2001, the gross agricultural product accounted for 4% of the national GDP. Traditionally a sea power, Portugal has had a strong tradition in the Portuguese fishing sector and is one of the countries with the highest fish consumption per capita. The main landing sites in Portugal (including Azores and Madeira), according to total landings in weight by year, are the harbours of Matosinhos, Peniche, Olhão, Sesimbra, Figueira da Foz, Sines, Portimão and Madeira. Portuguese-processed fish products are exported through several companies, under a number of different brands and registered trademarks, such as Ramirez, the world's oldest active canned fish producer. Portugal is a significant European minerals producer and is ranked among Europe's leading copper producers. The nation is also a notable producer of tin, tungsten and uranium. However, the country lacks the potential to conduct hydrocarbon exploration and aluminium, a limitation that has hindered the development of Portugal's mining and metallurgy sectors. Although the country has vast iron and coal reserves – mainly in the north – after the 1974 revolution and the consequent economic globalization, low competitiveness forced a decrease in the extraction activity for these minerals. The Panasqueira and Neves-Corvo mines are among the most recognized Portuguese mines that are still in operation. Portugal is rich in its lithium subsoil, which is especially concentrated in the districts of Guarda, Viseu, Vila Real and Viana do Castelo, while most of the country's lithium comes from the Gonçalo aplite-pegmatite field. The largest lithium mine in Europe is operated by Grupo Mota, Felmica, in the Guarda region, which is estimated to have reserves for 30 years of production. It has 5 more deposits in its possession. Savannah Resources in May 2018 announced a 52% increase in the estimated lithium resources at the Mina do Barroso Lithium Project in northern Portugal, saying the country could become the first European supplier of spodumene, a lithium-bearing mineral. The company said the estimated mineral resources at the mine now stood at 14 million tonnes. Lithium prices have risen in expectation of growing demand for the mineral, which is used in batteries for electric vehicles and for storing electricity from the power grid. Europe consumes more than 20 per cent of the global supply of battery-grade lithium but currently has to import all its supplies of the mineral. W Resources stated in 2018 that it had started a new drilling campaign at its São Martinho gold project in Portugal. The so-called reverse circulation drilling programme included 15 holes with around 2,000 metres of total drilling. The objective is to extend resources by integrating the data from 2016 drilling results with the expansion expected with the ongoing campaign. Secondary sector Industry is diversified, ranging from automotive (Volkswagen Autoeuropa and Peugeot Citroën) and bicycles, aerospace (Embraer and OGMA), electronics and textiles, to food, chemicals, cement and wood pulp. Volkswagen Group's AutoEuropa motor vehicle assembly plant in Palmela is among the largest foreign direct investment projects in Portugal. Modern non-traditional technology-based industries, such as aerospace, biotechnology and information technology, have been developed in several locations across the country. Alverca, Évora and Ponte de Sor are the main centres of the Portuguese aerospace industry, which is led by Brazil-based company Embraer and the Portuguese company OGMA. Following the turn of the 21st century, many major biotechnology and information technology industries have been founded, and are concentrated in the metropolitan areas of Lisbon, Porto, Braga, Coimbra and Aveiro. Tertiary sector The banking and insurance sectors performed well until the financial crisis of 2007–2008, and this partly reflected a rapid deepening of the market in Portugal. While sensitive to various types of market and underwriting risks, it has been estimated that overall both the life and non-life sectors will be able to withstand a number of severe shocks, even though the impact on individual insurers varies widely. Travel and tourism continue to be extremely important for Portugal. It has been necessary for the country to focus upon its niche attractions, such as health, nature and rural tourism, to stay ahead of its competitors. Portugal is among the top 20 most-visited countries in the world, receiving an average of 20,000,000 foreign tourists each year. In 2014, Portugal was elected The Best European Country by USA Today. In 2017, Portugal was elected both Europe's Leading Destination and in 2018 and 2019, World's Leading Destination Tourist hotspots in Portugal are: Lisbon, Cascais, Fatima, Algarve, Madeira, Porto and Coimbra. Lisbon attracts the sixteenth-most tourists among European cities (with seven million tourists occupying the city's hotels in 2006). Notable luxury destinations include the Portuguese Riviera and the Comporta Coast. Also, between 5–6 million religious pilgrims visit Fatima each year, where apparitions of the Virgin Mary to three shepherd children allegedly took place in 1917. The Sanctuary of Our Lady of Fatima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. The legend of the Rooster of Barcelos tells the story of a dead rooster's miraculous intervention in proving the innocence of a man who had been falsely accused and sentenced to death. The story is associated with the 17th-century calvary that is part of the collection of the Archaeological Museum located in Paço dos Condes, a gothic-style palace in Barcelos, a city in northwest Portugal. The Rooster of Barcelos is bought by thousands of tourists as a national souvenir. On 30 November 2016, the United Nations added the Portuguese tradition of making black pottery to the UNESCO Heritage Protection List. On 7 December 2017, the United Nations added the Bonecos de Estremoz – Toys of Estremoz tradition as an UNESCO Intangible Cultural Heritage of Humankind. Quaternary sector Scientific and technological research activities in Portugal are mainly conducted within a network of R&D units belonging to public universities and state-managed autonomous research institutions like the INETI – Instituto Nacional de Engenharia, Tecnologia e Inovação and the INRB – Instituto Nacional dos Recursos Biológicos. The funding and management of this research system is mainly conducted under the authority of the Ministry of Science, Technology and Higher Education (MCTES) and the MCTES's Fundação para a Ciência e Tecnologia (FCT). The largest R&D units of the public universities by volume of research grants and peer-reviewed publications, include biosciences research institutions like the Instituto de Medicina Molecular, the Centre for Neuroscience and Cell Biology, the IPATIMUP, the Instituto de Biologia Molecular e Celular and the Abel Salazar Biomedical Sciences Institute. Among the largest non-state-run research institutions in Portugal are the Instituto Gulbenkian de Ciência and the Champalimaud Foundation, a neuroscience and oncology research centre which awards every year one of the highest monetary prizes of any science prize in the world. A number of both national and multinational high-tech and industrial companies, are also responsible for research and development projects. One of the oldest learned societies of Portugal is the Sciences Academy of Lisbon, founded in 1779. Iberian bilateral state-supported research efforts include the International Iberian Nanotechnology Laboratory and the Ibercivis distributed computing platform, which are joint research programmes of both Portugal and Spain. Portugal is a member of several pan-European scientific organizations. These include the European Space Agency (ESA), the European Laboratory for Particle Physics (CERN), ITER, and the European Southern Observatory (ESO). Portugal has the largest aquarium in Europe, the Lisbon Oceanarium, and the Portuguese have several other notable organizations focused on science-related exhibits and divulgation, like the state agency Ciência Viva, a programme of the Portuguese Ministry of Science and Technology to the promotion of a scientific and technological culture among the Portuguese population, the Science Museum of the University of Coimbra, the National Museum of Natural History at the University of Lisbon, and the Visionarium. With the emergence and growth of several science parks throughout the world that helped create many thousands of scientific, technological and knowledge-based businesses, Portugal started to develop several science parks across the country. These include the Taguspark (in Oeiras), the Coimbra iParque (in Coimbra), the biocant (in Cantanhede), the Madeira Tecnopolo (in Funchal), Sines Tecnopolo (in Sines), Tecmaia (in Maia) and Parkurbis (in Covilhã). Companies locate in the Portuguese science parks to take advantage of a variety of services ranging from financial and legal advice through to marketing and technological support. Egas Moniz, a Portuguese physician who developed the cerebral angiography and leucotomy, received in 1949 the Nobel Prize in Physiology or Medicine – he is the first Portuguese recipient of a Nobel Prize and the only in the sciences. The European Innovation Scoreboard 2011, placed Portugal-based innovation in the 15th position, with an impressive increase in innovation expenditure and output. Portugal was ranked 31st in the Global Innovation Index in 2020, up from 32nd in 2019. Transport By the early-1970s, Portugal's fast economic growth with increasing consumption and purchase of new automobiles set the priority for improvements in transportation. Again in the 1990s, after joining the European Economic Community, the country built many new motorways. Today, the country has a road network, of which almost are part of system of 44 motorways. Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5). Although a few other tracts were created (around 1960 and 1970), it was only after the beginning of the 1980s that large-scale motorway construction was implemented. In 1972, Brisa, the highway concessionaire, was founded to handle the management of many of the region's motorways. On many highways, a toll needs to be paid (see Via Verde). Vasco da Gama bridge is the longest bridge in Europe at 12.345 km. Continental Portugal's territory is serviced by four international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Air Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been suspended due to austerity measures. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal. One other important airport is the Aeroporto Internacional das Lajes on the island of Terceira in the Azores. This airport serves as one of two international airports serving countries outside the European Union for all nine islands of the Azores. It also serves as a military air base for the United States Air Force. The base remains in use to the present day. A national railway system that extends throughout the country and into Spain, is supported and administered by Comboios de Portugal (CP). Rail transport of passengers and goods is derived using the of railway lines currently in service, of which are electrified and about allow train speeds greater than . The railway network is managed by Infraestruturas de Portugal while the transport of passengers and goods are the responsibility of CP, both public companies. In 2006, the CP carried 133,000,000 passengers and of goods. The major seaports are located in Sines, Lisbon, Leixões, Setúbal, Aveiro, Figueira da Foz, and Faro. The two largest metropolitan areas have subway systems: Lisbon Metro and Metro Sul do Tejo in the Lisbon metropolitan area and Porto Metro in the Porto Metropolitan Area, each with more than of lines. In Portugal, Lisbon tram services have been supplied by the Companhia de Carris de Ferro de Lisboa (Carris), for over a century. In Porto, a tram network, of which only a tourist line on the shores of the Douro remains, began construction on 12 September 1895 (a first for the Iberian Peninsula). All major cities and towns have their own local urban transport network, as well as taxi services. Energy Portugal has considerable resources of wind and river power, the two most cost-effective renewable energy sources. Since the turn of the 21st century, there has been a trend towards the development of a renewable resource industry and reduction of both consumption and use of fossil fuels. In 2006, the world's largest solar power plant at that date, the Moura Photovoltaic Power Station, began operating near Moura, in the south, while the world's first commercial wave power farm, the Aguçadoura Wave Farm, opened in the Norte region (2008). By the end of 2006, 66% of the country's electrical production was from coal and fuel power plants, while 29% were derived from hydroelectric dams, and 6% by wind energy. In 2008, renewable energy resources were producing 43% of the nation's consumption of electricity, even as hydroelectric production decreased with severe droughts. As of June 2010, electricity exports had outnumbered imports. In the period between January and May 2010, 70% of the national production of energy came from renewable sources. Portugal's national energy transmission company, Redes Energéticas Nacionais (REN), uses sophisticated modelling to predict weather, especially wind patterns, and computer programs to calculate energy from the various renewable-energy plants. Before the solar/wind revolution, Portugal had generated electricity from hydropower plants on its rivers for decades. New programmes combine wind and water: wind-driven turbines pump water uphill at night, the most blustery period; then the water flows downhill by day, generating electricity, when consumer demand is highest. Portugal's distribution system is also now a two-way street. Instead of just delivering electricity, it draws electricity from even the smallest generators, like rooftop solar panels. The government aggressively encouraged such contributions by setting a premium price for those who buy rooftop-generated solar electricity. Demographics The Statistics Portugal () estimates that, according to the 2021 census, the population was 10,344,802 (of which 52% was female, 48% was male). This population has been relatively homogeneous for most of its history: a single religion (Roman Catholicism) and a single language have contributed to this ethnic and national unity. The most important demographic influence in the modern Portuguese seems to be the oldest one; current interpretation of Y-chromosome and mtDNA data suggests that the Portuguese have their origin in Paleolithic peoples that began arriving to the European continent around 45,000 years ago. All subsequent migrations did leave an impact, genetically and culturally, but the main population source of the Portuguese is still Paleolithic. Genetic studies show Portuguese populations not to be significantly different from other European populations. Portuguese people have a preponderancy of genetics (Iron Age Period) which belong to R1b haplogroup family along with Brythonic, Alpine and Goidelic genetical markers. Also expectable but not so common are South European (Sardinian, Italian and Balkans), broadly North-western (West Germanic) and to a lesser extent British/Irish (Brythonic/Gaelic) and French (Alpine). With a low confidence range there are Scandinavian and East European genetical markers. Other sources would point out a small presence of Berber and Jewish that would be also part of a low confidence region. Native Portuguese are an Iberian ethnic group and they form 95% of the whole population, whose ancestry is very similar to Spaniards and have strong ties with fellow Atlantic Arc countries like Ireland, British Isles, France and Belgium due to maritime trade dated as far back as the Bronze Age. These maritime contacts and the prevalence of R1b haplogroup as the main genetical marker of these countries suggest a common ancestry and cultural proximity. Other maritime contacts with the Mediterranean especially with Greeks, Phoenicians, Romans and Moors added some particular phenotypes in southern Portugal and particularly southern Spain (the Tartessos culture), making Portugal and north-western Spain a bridge between north-western Europe and the Mediterranean but maintaining the Atlantic character. Despite the good economic development in the past three decades the Portuguese were the shortest in Europe since 1890. This emerging height gap took place in the 1840s and has increased since. One of the driving factors was the modest real wage development, given the late industrialization and economic growth in Portugal compared to the European core. Another determinant was the delayed human capital formation. The total fertility rate (TFR) was estimated at 1.52 children born/woman, one of the lowest in the world, which is below the replacement rate of 2.1, it remains considerably below the high of 5.02 children born per woman in 1911. In 2016, 52.8% of births were to unmarried women. Like most Western countries, Portugal has to deal with low fertility levels: the country has experienced a sub-replacement fertility rate since the 1980s. Portugal subsequently has the 17th oldest population in the world, with the average age of 43.7 years. The structure of Portuguese society is characterized by a significant inequality which in 2016 placed the country in the lowest seventh of the Social Justice Index for the European Union. Portugal's parliament in 2018 approved a budget plan for 2019 that includes tax breaks for returning emigrants in a bid to lure back those who left during the financial crisis of 2007–2008. The expansionary 2019 budget, backed by a left-wing majority in parliament, also aims to boost the purchasing power of households while cutting the already low deficit even further. Returning emigrants will be allowed to declare only half their taxable income for five years if they return, provided they lived abroad for at least three years. The "Return Programme" is to run for two years. Around 500,000 residents left Portugal between 2010 and 2015 after the Great Recession. Although some 350,000 have since returned, Lisbon wants to tempt the rest to come home – in a similar scheme to the Irish one. Portugal has approved a credit line for Portuguese emigrants aiming to invest in the country on their return. Furthermore, Emigrants returning in 2019 and 2020 will see their taxes halved as part of the stimulus to bring native Portuguese back and revitalize the population and promote continued economic growth – as Portugal struggles with a low birth rate and an ageing population. According to projections by the national statistics office, Portugal's population will fall to 7.7 million by 2080 from 10.3 million now and the population will continue to age. Urbanization Metropolitan areas There are two Greater Metropolitan Areas (GAMs): Lisbon and Porto. The following is a list of those with mainland Functional Urban Areas (FUA). Regions by HDI This is a list of NUTS2 statistical regions of Portugal by Human Development Index as of 2019. Immigration In 2007, Portugal had 10,617,575 inhabitants, of whom about 332,137 were legal immigrants. In 2015, Portugal had 10,341,330 inhabitants, of whom about 383,759 were legal migrants, making up 3.7% of the population. In 2017, Portugal had 416,682 legal residents of foreign origin, of which 203,753 identified as male, and 212,929 as female. As of 2020, 32,147 residents of foreign origin acquired Portuguese nationality, of which 17,021 were female and 15,126 were male. Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975. Since the 1990s, along with a boom in construction, several new waves of Ukrainian, Brazilian, Lusophone Africans and other Africans have settled in the country. Romanians, Moldovans, Kosovo Albanians, Russians and Chinese have also migrated to the country. Portugal's Romani population is estimated to be at about 40,000. Numbers of Venezuelan, Pakistani and Indian migrants are also significant. It is estimated that over 30,000 seasonal, often illegal immigrants work in agriculture, mainly in the south where they are often exploited by organized seasonal workers' networks. The workers sometimes get paid less than half the minimum pay established by law. These migrants, who often arrive without due documentation or work contracts, make up over 90% of agricultural workers in the south of Portugal. Most are Indo-Asians, from India, Bangladesh, Nepal, Pakistan and Thailand. In the interior of the Alentejo there are many African workers. Significant numbers also come from Eastern Europe, Moldova, Ukraine, Romania and Brazil. In addition, a number of EU citizens, mostly from the United Kingdom or other northern European countries, have become permanent residents in the country (with the British community being mostly composed of retired pensioners who live in the Algarve and Madeira). Religion According to the 2011 Census, 81.0% of the Portuguese population was Roman Catholic Christian. The country has small Protestant, Latter-day Saint, Muslim, Hindu, Sikh, Eastern Orthodox Church, Jehovah's Witnesses, Baháʼí, Buddhist, Jewish and Spiritist communities. Influences from African Traditional Religion and Chinese Traditional Religion are also felt among many people, particularly in fields related with Traditional Chinese Medicine and Traditional African Herbal Medicine. Some 6.8% of the population declared themselves to be non-religious, and 8.3% did not give any answer about their religion. Many Portuguese holidays, festivals and traditions have a Christian origin or connotation. Although relations between the Portuguese state and the Roman Catholic Church were generally amiable and stable since the earliest years of the Portuguese nation, their relative power fluctuated. In the 13th and 14th centuries, the church enjoyed power and close identification with early Portuguese nationalism and the foundation of the Portuguese educational system, including its first university. The growth of the Portuguese overseas empire made its missionaries important agents of colonization, with important roles in the education and evangelization of people from all the inhabited continents. The growth of liberal and nascent republican movements during the eras leading to the formation of the First Portuguese Republic (1910–26) changed the role and importance of organized religion. Portugal is a secular state: church and state were formally separated during the First Portuguese Republic, and this was reiterated in the 1976 Portuguese Constitution. Other than the Constitution, the two most important documents relating to religious freedom in Portugal are the 1940 Concordata (later amended in 1971) between Portugal and the Holy See and the 2001 Religious Freedom Act. Languages Portuguese is the official language of Portugal. It is a Romance language that is derived from Galician-Portuguese, which was spoken in what is now Galicia and Northern Portugal. There are still strong similarities between the Galician and Portuguese cultures. Galicia is a consultative observer of the Community of Portuguese Language Countries. The Portuguese language is derived from the Latin spoken by the romanized pre-Roman peoples of the Iberian Peninsula around 2000 years ago – particularly the Celts, Conii, Lusitanians and Turduli. In the 15th and 16th centuries, the language spread worldwide as Portugal established a colonial and commercial empire between 1415 and 1999. Portuguese is spoken as a native language in five different continents, with Brazil accounting for the largest number of native Portuguese speakers of any country. In 2013 the Portuguese language is the official language spoken in Brazil, Angola, Mozambique, Cape Verde, São Tomé and Príncipe, Guinea-Bissau, Equatorial Guinea, and East Timor. These countries, plus Macau Special Administrative Region (People's Republic of China) where Portuguese is co-official with Cantonese, make up the Lusosphere, a term derived from the ancient Roman province of "Lusitania", which currently matches the Portuguese territory south of the Douro river. Mirandese is also recognized as a co-official regional language in some municipalities of North-Eastern Portugal. It is part of the Astur-Leonese group of languages. An estimate of between 6,000 and 7,000 Mirandese speakers has been documented for Portugal. Furthermore, a particular dialect known as Barranquenho, spoken in Barrancos, is also officially recognized and protected in Portugal since 2021. Minderico, a sociolect of the Portuguese language, is spoken by around 500 people in the town of Minde. According to the International English Proficiency Index, Portugal has a high proficiency level in English, higher than those of other Romance-speaking European countries like Italy, France or Spain. Education The educational system is divided into preschool (for those under age 6), basic education (9 years, in three stages, compulsory), secondary education (3 years, compulsory since 2010), and higher education (subdivided in university and polytechnic education). Universities are usually organized into faculties. Institutes and schools are also common designations for autonomous subdivisions of Portuguese higher education institutions. The total adult literacy rate is 99.4 per cent. Portuguese primary school enrolments are 100 per cent. According to the Programme for International Student Assessment (PISA) 2018, Portugal scored around the OECD average in reading, mathematics and science. In reading and mathematics, mean performance in 2018 was close to the level observed in 2009 to 2015; in science, mean performance in 2018 was below that of 2015, and returned close to the level observed in 2009 and 2012. About 46,9% of college-age citizens (20 years old) attend one of Portugal's higher education institutions (compared with 50% in the United States and 35% in the OECD countries). In addition to being a destination for international students, Portugal is also among the top places of origin for international students. All higher education students, both domestic and international, totalled 380,937 in 2005. Portuguese universities have existed since 1290. The oldest Portuguese university was first established in Lisbon before moving to Coimbra. Historically, within the scope of the Portuguese Empire, the Portuguese founded the oldest engineering school of the Americas (the Real Academia de Artilharia, Fortificação e Desenho of Rio de Janeiro) in 1792, as well as the oldest medical college in Asia (the Escola Médico-Cirúrgica of Goa) in 1842. Presently, the largest university in Portugal is the University of Lisbon. The Bologna process has been adopted by Portuguese universities and poly-technical institutes in 2006. Higher education in state-run educational establishments is provided on a competitive basis, a system of numerus clausus is enforced through a national database on student admissions. However, every higher education institution offers also a number of additional vacant places through other extraordinary admission processes for sportsmen, mature applicants (over 23 years old), international students, foreign students from the Lusosphere, degree owners from other institutions, students from other institutions (academic transfer), former students (readmission), and course change, which are subject to specific standards and regulations set by each institution or course department. Most student costs are supported with public money. However, with the increasing tuition fees a student has to pay to attend a Portuguese state-run higher education institution and the attraction of new types of students (many as international students and part-time students or in evening classes) like employees, businessmen, parents, pensioners and foreigners (most prominently from Brazil, a Portuguese-speaking country), many departments make a substantial profit from every additional student enrolled in courses, with benefits for the college or university's gross tuition revenue and without loss of educational quality (teacher per student, computer per student, classroom size per student, etc.). Portugal has entered into cooperation agreements with the Massachusetts Institute of Technology and other US institutions to further develop and increase the effectiveness of Portuguese higher education and research. Health According to the Human Development Report, the average life expectancy in Portugal had reached 82 years in 2017; in 2020 it was estimated at 82.11 years. As projected by the United Nations, the life expectancy of the Portuguese population will be over 90 years when we reach 2100. The trajectory of the Portuguese life expectancy is visualized with historical data from 1950 and future projections up to 2100, as can be seen in the graph on the left. Portugal ranks 12th in the best public health systems in the world, ahead of other countries like the United Kingdom, Germany or Sweden. The Portuguese health system is characterized by three coexisting systems: the National Health Service (Serviço Nacional de Saúde, SNS), special social health insurance schemes for certain professions (health subsystems) and voluntary private health insurance. The SNS provides universal coverage. In addition, about 25% of the population is covered by the health subsystems, 10% by private insurance schemes and another 7% by mutual funds. The Ministry of Health is responsible for developing health policy as well as managing the SNS. Five regional health administrations are in charge of implementing the national health policy objectives, developing guidelines and protocols and supervising health care delivery. Decentralization efforts have aimed at shifting financial and management responsibility to the regional level. In practice, however, the autonomy of regional health administrations over budget setting and spending has been limited to primary care. The SNS is predominantly funded through general taxation. Employer (including the state) and employee contributions represent the main funding sources of the health subsystems. In addition, direct payments by the patient and voluntary health insurance premiums account for a large proportion of funding. Similar to the other Eur-A countries, most Portuguese die from noncommunicable diseases. Mortality from cardiovascular diseases (CVD) is higher than in the eurozone, but its two main components, ischaemic heart disease and cerebrovascular disease, display inverse trends compared with the Eur-A, with cerebrovascular disease being the single biggest killer in Portugal (17%). Portuguese people die 12% less often from cancer than in the Eur-A, but mortality is not declining as rapidly as in the Eur-A. Cancer is more frequent among children as well as among women younger than 44 years. Although lung cancer (slowly increasing among women) and breast cancer (decreasing rapidly) are scarcer, cervical cancer and prostate cancer are more frequent. Portugal has the highest mortality rate for diabetes in the Eur-A, with a sharp increase since the 1980s. Portugal's infant mortality rate is around 2 deaths per 1000 newborns, with 2.4 deaths per 1000 live births. People are usually well informed about their health status, the positive and negative effects of their behaviour on their health, and their use of health care services. Yet their perceptions of their health, can differ from what administrative and examination-based data show about levels of illness within populations. Thus, survey results based on self-reporting at household level, complement other data on health status and the use of services. Only one third of adults rated their health as good or very good in Portugal (Kasmel et al., 2004). This is the lowest of the Eur-A countries reporting and reflects the relatively adverse situation of the country in terms of mortality and selected morbidity. Hospital de Santa Maria is the largest university hospital in Portugal. Culture Portugal has developed a specific culture while being influenced by various civilizations that have crossed the Mediterranean and the European continent, or were introduced when it played an active role during the Age of Discovery. In the 1990s and 2000s (decade), Portugal modernized its public cultural facilities, in addition to the Calouste Gulbenkian Foundation established in 1956 in Lisbon. These include the Belém Cultural Centre in Lisbon, Serralves Foundation and the Casa da Música, both in Porto, as well as new public cultural facilities like municipal libraries and concert halls that were built or renovated in many municipalities across the country. Portugal is home to 17 UNESCO World Heritage Sites, ranking it 9th in Europe and 18th in the world. Architecture Traditional architecture is distinctive and include the Manueline, also known as Portuguese late Gothic a sumptuous, composite Portuguese style of architectural ornamentation of the first decades of the 16th century, followed by Pombaline style of the 18th century. A 20th-century interpretation of traditional architecture, Soft Portuguese style, appears extensively in major cities, especially Lisbon. Modern Portugal has given the world renowned architects like Eduardo Souto de Moura, Álvaro Siza Vieira (both Pritzker Prize winners) and Gonçalo Byrne. In Portugal Tomás Taveira is also noteworthy, particularly for stadium design. Cinema Portuguese cinema has a long tradition, reaching back to the birth of the medium in the late 19th century. António Lopes Ribeiro, António Reis, | to pursue International Monetary Fund (IMF)-monitored stabilization programmes in 1977–78 and 1983–85. In 1986, Portugal, along with Spain, joined the European Economic Community (EEC) that later became the European Union (EU). In the following years Portugal's economy progressed considerably as a result of EEC/EU structural and cohesion funds and Portuguese companies' easier access to foreign markets. Portugal's last overseas and Asian colonial territory, Macau, was peacefully handed over to the People's Republic of China (PRC) on 20 December 1999, under the 1987 joint declaration that set the terms for Macau's handover from Portugal to the PRC. In 2002, the independence of East Timor (Asia) was formally recognized by Portugal, after an incomplete decolonization process that was started in 1975 because of the Carnation Revolution, but interrupted by an Indonesian armed invasion and occupation. On 26 March 1995, Portugal started to implement Schengen Area rules, eliminating border controls with other Schengen members while simultaneously strengthening border controls with non-member states. In 1996 the country was a co-founder of the Community of Portuguese Language Countries (CPLP) headquartered in Lisbon. In 1996, Jorge Sampaio became president. He won re-election in January 2001. Expo '98 took place in Portugal and in 1999 it was one of the founding countries of the euro and the eurozone. On 5 July 2004, José Manuel Barroso, then Prime Minister of Portugal, was nominated President of the European Commission, the most powerful office in the European Union. On 1 December 2009, the Treaty of Lisbon entered into force, after it had been signed by the European Union member states on 13 December 2007 in the Jerónimos Monastery, in Lisbon, enhancing the efficiency and democratic legitimacy of the Union and improving the coherence of its action. Ireland was the only EU state to hold a democratic referendum on the Lisbon Treaty. It was initially rejected by voters in 2008. Economic disruption and an unsustainable growth in government debt during the financial crisis of 2007–2008 led the country to negotiate in 2011 with the IMF and the European Union, through the European Financial Stability Mechanism (EFSM) and the European Financial Stability Facility (EFSF), a loan to help the country stabilize its finances. Geography The territory of Portugal includes an area on the Iberian Peninsula (referred to as the continent by most Portuguese) and two archipelagos in the Atlantic Ocean: the archipelagos of Madeira and the Azores. It lies between latitudes 30° and 42° N, and longitudes 32° and 6° W. Mainland Portugal is split by its main river, the Tagus, that flows from Spain and disgorges in the Tagus Estuary, in Lisbon, before escaping into the Atlantic. The northern landscape is mountainous towards the interior with several plateaus indented by river valleys, whereas the south, including the Algarve and the Alentejo regions, is characterized by rolling plains. Portugal's highest peak is the similarly named Mount Pico on the island of Pico in the Azores. This ancient volcano, which measures is an iconic symbol of the Azores, while the Serra da Estrela on the mainland (the summit being above sea level) is an important seasonal attraction for skiers and winter sports enthusiasts. The archipelagos of Madeira and the Azores are scattered within the Atlantic Ocean: the Azores straddling the Mid-Atlantic Ridge on a tectonic triple junction, and Madeira along a range formed by in-plate hotspot geology. Geologically, these islands were formed by volcanic and seismic events. The last terrestrial volcanic eruption occurred in 1957–58 (Capelinhos) and minor earthquakes occur sporadically, usually of low intensity. Portugal's exclusive economic zone, a sea zone over which the Portuguese have special rights over the exploration and use of marine resources, has 1,727,408 km2. This is the 3rd largest exclusive economic zone of the European Union and the 20th largest in the world. Climate Portugal is mainly characterized by a Mediterranean climate (Csa in the South, central interior, and the Douro river valley; Csb in the North, Central west and Vicentine Coast), temperate maritime climate (Cfb) in the mainland north-western highlands and mountains, and in some high altitude zones of the Azorean islands; a semi-arid climate in certain parts of the Beja District far south (BSk) and in Porto Santo Island (BSh), a warm desert climate (BWh) in the Selvagens Islands and a humid subtropical climate in the western Azores (Cfa), according to the Köppen-Geiger Climate Classification. It is one of the warmest countries in Europe: the annual average temperature in mainland Portugal varies from in the mountainous interior north to in the south and on the Guadiana river basin. There are however, variations from the highlands to the lowlands: Spanish biologist Salvador Rivas Martinez presents several different bioclimatic zones for Portugal. The Algarve, separated from the Alentejo region by mountains reaching up to in Alto da Fóia, has a climate similar to that of the southern coastal areas of Spain or Southwest Australia. Annual average rainfall in the mainland varies from just over on the Peneda-Gerês National Park to less than in southern parts of Alentejo. Mount Pico is recognized as receiving the largest annual rainfall (over per year) in Portugal, according to Instituto Português do Mar e da Atmosfera. In some areas, such as the Guadiana basin, annual diurnal average temperatures can be as high as , and summer's highest temperatures are routinely over . The record high of was recorded in Amareleja, although this might not be the hottest spot in summer, according to satellite readings. Snowfalls occur regularly in the winter in the interior North and Centre of the country in districts such as Guarda, Bragança, Viseu and Vila Real, particularly on the mountains. In winter, temperatures may drop below , particularly in Serra da Estrela, Serra do Gerês, Serra do Marão and Serra de Montesinho. In these places snow can fall any time from October to May. In the South of the country snowfalls are rare but still occur in the highest elevations. While the official absolute minimum by IPMA is in Penhas da Saúde and Miranda do Douro, lower temperatures have been recorded, such as by Bragança Polytechnic Institute in the outskirts of the city in 1983, and below in Serra da Estrela. Continental Portugal has around 2300 to 3200 hours of sunshine a year, an average of 4–6 h in winter and 10–12 h in the summer, with higher values in the south-east, south-west and the Algarve coast and lower in the north-west. Insolation values are lower in the archipelagos, with around 1600 h in the humid Flores Island and around 2300 h in the island of Madeira and Porto Santo. Insolation in the Selvagens is thought to be higher due to weaker orographic lift and their relative proximity to the Sahara Desert. Portugal's central west and southwest coasts have an extreme ocean seasonal lag, sea temperatures are warmer in October than in July and are their coldest in March. The average sea surface temperature on the west coast of mainland Portugal varies from in January−March to in August−October while on the south coast it ranges from in January−March and rises in the summer to about , occasionally reaching . In the Azores, around in February−April to in July−September, and in Madeira, around in February−April to in August−October. Both the archipelagos of the Azores and Madeira have a subtropical climate, although variations between islands exist, making weather predictions very difficult (owing to rough topography). The Madeira and Azorean archipelagos have a narrower temperature range, with annual average temperatures exceeding in some parts of the coast (according to the Portuguese Meteorological Institute). Some islands in Azores do have drier months in the summer. Consequently, the islands of the Azores have been identified as having a Mediterranean climate (both Csa and Csb types), while some islands (such as Flores or Corvo) are classified as Humid subtropical (Cfa), transitioning into an Oceanic climate (Cfb) at higher altitudes, according to Köppen-Geiger classification. Porto Santo Island in Madeira has a warm semi-arid climate (BSh). The Savage Islands, which are part of the regional territory of Madeira and a nature reserve are unique in being classified as a desert climate (BWh) with an annual average rainfall of approximately . The sea surface temperature in these islands varies from in winter to in the summer occasionally reaching . Biodiversity Portugal is located on the Mediterranean Basin, the third most diverse hotspot of flora in the world. Due to its geographical and climatic context - between the Mediterranean and the Atlantic - Portugal has a high level of biodiversity on land and at sea. It is home to six terrestrial ecoregions: Azores temperate mixed forests, Cantabrian mixed forests, Madeira evergreen forests, Iberian sclerophyllous and semi-deciduous forests, Northwest Iberian montane forests, and Southwest Iberian Mediterranean sclerophyllous and mixed forests. Over 22% of its land area is included in the Natura 2000 network, including 62 special conservation areas and 88 types of protected landscape natural habitats. Eucalyptus, cork oak and maritime pine together make up 71% of the total forested area of continental Portugal, followed by the holm oak, the stone pine, the other oak trees (Q. robur, Q. faginea and Q. pyrenaica) and the sweet chestnut, respectively. On Madeira, laurisilva (recognized as a World Heritage Site) dominates the landscape, especially on the northern slope. The predominant species in this forest include Laurus novocanariensis, Apollonias barbujana, Ocotea foetens and Persea indica. Before human occupation the Azores were also rich in dense laurisilva forests, today these native forests are undermined by the introduced Pittosporum undulatum and Cryptomeria japonica. There have been several projects aimed to recover the Laurisilva present in the Azores. Remnants of these laurisilva forests are also present in continental Portugal with its few living testimonies Laurus nobilis, Prunus lusitanica, Arbutus unedo, Myrica faya and Rhododendron ponticum. These geographical and climatic conditions facilitate the introduction of exotic species that later turn to be invasive and destructive to the native habitats. More than 20% of the total number of extant species in continental Portugal are exotic. On Madeira, around 36% and on the Azores, around 70% are exotic. Due to this, Portugal was placed 168th globally out of 172 countries on the Forest Landscape Integrity Index in 2019. Portugal is the second country in Europe with the highest number of threatened species (488 as of 2020). Portugal as a whole is an important stopover for migratory bird species: the marshes of the eastern Algarve (Ria Formosa, Castro Marim) and the Lisbon Region (Tagus Estuary, Sado Estuary) hosting various aquatic bird species, the Bonelli's eagle and Egyptian vulture on the valleys of the Douro International, the black stork and griffon vulture on the Tagus International, the seabird sanctuaries of the Savage Islands and Berlengas and the highlands of Madeira and São Miguel all represent the great diversity of wild avian species (around 450 in continental Portugal), not only migratory but also endemic (e.g. trocaz pigeon, Azores bullfinch) or exotic (crested myna, pin-tailed whydah). The large mammalian species of Portugal (the fallow deer, red deer, roe deer, Iberian ibex, wild boar, red fox, Iberian wolf and Iberian lynx) were once widespread throughout the country, but intense hunting, habitat degradation and growing pressure from agriculture and livestock reduced population numbers on a large scale in the 19th and early 20th century, others, such as the Portuguese ibex were even led to extinction. Today, these animals are re-expanding their native range. Smaller mammals include the red squirrel, European badger, Eurasian otter, Egyptian mongoose, Granada hare, European rabbit, common genet, European wildcat, among others. Due to their isolated location, the volcanic islands of the Azores, Madeira and Salvages, part of Macaronesia, have many endemic species that have evolved independently from their European, African and occasionally American relatives. The Portuguese west coast is part of the four major Eastern Boundary Upwelling Systems of the ocean. This seasonal upwelling system typically seen during the summer months brings cooler, nutrient rich water up to the sea surface promoting phytoplankton growth, zooplankton development and the subsequent rich diversity in pelagic fish and other marine invertebrates. This, adding to its large EEZ makes Portugal one of the largest fish consumers in the world per capita. Sardines (Sardina pilchardus) and horse mackerel (Trachurus trachurus) are collected in the thousands every year. while blue whiting, monkfish, Atlantic cod, cephalopods, skates or any other form of seafood are traditionally fished in the local coastal villages. This upwelling also allows Portugal to have kelp forests which are otherwise very uncommon or non-existent on the Mediterranean. 73% of the freshwater fish occurring in the Iberian Peninsula are endemic, the largest out of any region in Europe. Many of these endemic species are concentrated in bodies of water of the central western region (one exclusively endemic), these and other bodies of water throughout the Peninsula are mostly temporary and prone to drought every year, placing most of these species under Threatened status. Around 24 to 28 species of cetacean roam through the Azores, making it one of four places in the world where most species of this infraorder occur. Starting in the mid-19th century and ceasing in 1984, whaling (especially of sperm whale) heavily exploited this diversity. Beginning in the early 90s, whale watching quickly grew to popularity and is now one of the main economic activities in the Portuguese archipelago. Some protected areas in Portugal other than the ones previously mentioned include: the Serras de Aire e Candeeiros with its limestone formations, paleontological history and great diversity in bats and orchids, the Southwest Alentejo and Vicentine Coast Natural Park with its well preserved, wild coastline. the Montesinho Natural Park which hosts some of the only populations of Iberian wolf and a recently sighted Iberian brown bear, considered to be extinct in the country; among others. Government and politics Portugal has been a semi-presidential representative democratic republic since the ratification of the Constitution of 1976, with Lisbon, the nation's largest city, as its capital. The Constitution grants the division or separation of powers among four bodies referred as "organs of Sovereignty": the President of the Republic, the Government, the Assembly of the Republic and the Courts. The President, who is elected to a five-year term, has an executive role: the current President is Marcelo Rebelo de Sousa. The Assembly of the Republic is a single chamber parliament composed of a maximum of 230 deputies elected for a four-year term. The Government is headed by the Prime Minister (currently António Costa) and includes Ministers and Secretaries of State. The Courts are organized into several levels, among the judicial, administrative and fiscal branches. The Supreme Courts are institutions of last resort/appeal. A thirteen-member Constitutional Court oversees the constitutionality of the laws. Portugal operates a multi-party system of competitive legislatures/local administrative governments at the national, regional and local levels. The Assembly of the Republic, Regional Assemblies and local municipalities and parishes, are dominated by two political parties, the Socialist Party and the Social Democratic Party, in addition to the Unitary Democratic Coalition (Portuguese Communist Party and Ecologist Party "The Greens"), the Left Bloc and the Democratic and Social Centre – People's Party, which garner between 5 and 15% of the vote regularly. Presidency of the Republic The Head of State of Portugal is the President of the Republic, elected to a five-year term by direct, universal suffrage. Presidential powers include the appointment of the Prime Minister and the other members of the Government (where the President takes into account the results of legislative elections); dismissing the Prime Minister; dissolving the Assembly of the Republic (to call early elections); vetoing legislation (which may be overridden by the Assembly); and declaring a state of war or siege. The President has also supervisory and reserve powers and is the ex officio Commander-in-Chief of the Armed Forces. The President is advised on issues of importance by the Council of State, which is composed of six senior civilian officers, any former Presidents elected under the 1976 Constitution, five-members chosen by the Assembly, and five selected by the president. Government The Government is headed by the presidentially appointed Prime Minister, also including one or more Deputy Prime Ministers, Ministers, Secretaries of State and Under-Secretaries of State. The Government is both the organ of sovereignty that conducts the general politics of the country and the superior body of the public administration. It has essentially Executive powers, but has also limited legislative powers. The Government can legislate about its own organization, about areas covered by legislative authorizations conceded by the Assembly of the Republic and about the specific regulation of generalist laws issued by the Assembly. The Council of Ministers – under the presidency of the Prime Minister (or the President of Portugal at the latter's request) and the Ministers (may also include one or more Deputy Prime Ministers) – acts as the cabinet. Each government is required to define the broad outline of its policies in a programme, and present it to the Assembly for a mandatory period of debate. The failure of the Assembly to reject the government programme by an absolute majority of deputies confirms the cabinet in office. Parliament The Assembly of the Republic, in Lisbon, is the national parliament of Portugal. It is the main legislative body, although the Government also has limited legislative powers. The Assembly of the Republic is a unicameral body composed of up to 230 deputies. Elected by universal suffrage according to a system of closed party-list proportional representation, deputies serve four-year terms of office, unless the President dissolves the Assembly and calls for new elections. Currently the Government (PS) and the parties supporting it through a confidence-and-supply agreement (BE, PCP, PEV) control parliament with the most seats. The PSD and CDS-PP parties form the opposition to the government alongside PAN, Chega, Iniciativa Liberal and Partido Livre. Foreign relations A member state of the United Nations since 1955, Portugal is also a founding member of NATO (1949), OECD (1961) and EFTA (1960); it left the last in 1986 to join the European Economic Community, which became the European Union in 1993. In 1996, Portugal co-founded the Community of Portuguese Language Countries (CPLP), also known as the Lusophone Commonwealth, an international organization and political association of Lusophone nations across four continents, where Portuguese is an official language. The global headquarters of the CPLP is in Penafiel Palace, in Lisbon. António Guterres, who has served as Prime Minister of Portugal from 1995 to 2002 and UN High Commissioner for Refugees from 2005 to 2015, assumed the post of UN Secretary-General on 1 January 2017; making him the first Secretary-General from Western Europe since Kurt Waldheim of Austria (1972–1981), the first former head of government to become Secretary-General and the first Secretary-General born after the establishment of the United Nations on 26 June 1945. In addition, Portugal was a full member of the Latin Union (1983) and the Organization of Ibero-American States (1949). It has a friendship alliance and dual citizenship treaty with its former colony, Brazil. Portugal and the United Kingdom share the world's oldest active military accord through their Anglo-Portuguese Alliance (Treaty of Windsor), which was signed in 1373. There are two international territorial disputes, both with Spain: Olivenza. Under Portuguese sovereignty since 1297, the municipality of Olivenza was ceded to Spain under the Treaty of Badajoz in 1801, after the War of the Oranges. Portugal claimed it back in 1815 under the Treaty of Vienna. However, since the 19th century, it has been continuously ruled by Spain which considers the territory theirs not only de facto but also de jure. The Ilhas Selvagens (Savage Islands). The archipelago is under Portuguese domination but is geographically closer to the Canary Islands (165 km) than to Madeira (280 km). Found in 1364 by Italian navigators, the islands belonged to private owners until 1971, when the Portuguese government bought them and established a natural reserve area covering the whole archipelago. The islands have been claimed by Spain since 1911 and the dispute has caused some periods of political tension between the two countries. The main problem is not so much their intrinsic value but the fact that they expand the Exclusive Economic Zone of Portugal considerably to the south. Military The armed forces have three branches: Navy, Army and Air Force. They serve primarily as a self-defence force whose mission is to protect the territorial integrity of the country and provide humanitarian assistance and security at home and abroad. , the three branches numbered 39,200 active personnel including 7,500 women. Portuguese military expenditure in 2009 was 5 billion US$, representing 2.1 per cent of GDP. Military conscription was abolished in 2004. The minimum age for voluntary recruitment is 18 years. The Army (21,000 personnel) comprises three brigades and other small units. An infantry brigade (mainly equipped with Pandur II APC), a mechanized brigade (mainly equipped with Leopard 2 A6 tanks and M113 APC) and a Rapid Reaction Brigade (consisting of paratroopers, commandos and rangers). The Navy (10,700 personnel, of which 1,580 are marines), the world's oldest surviving naval force, has five frigates, seven corvettes, two submarines, and 28 patrol and auxiliary vessels. The Air Force (7,500 personnel) has the Lockheed F-16 Fighting Falcon as the main combat aircraft. In addition to the three branches of the armed forces, there is the National Republican Guard, a security force subject to military law and organization (gendarmerie) comprising 25,000 personnel. This force is under the authority of both the Defence and the Interior Ministry. It has provided detachments for participation in international operations in Iraq and East Timor. The United States maintains a military presence with 770 troops in the Lajes Air Base at Terceira Island, in the Azores. The Allied Joint Force Command Lisbon (JFC Lisbon) – one of the three main subdivisions of NATO's Allied Command Operations – it is based in Oeiras, near Lisbon. In the 20th century, Portugal engaged in two major conflicts: World War I and the Portuguese Colonial War (1961–1974). After the end of the Portuguese Empire in 1975, the Portuguese Armed Forces have participated in peacekeeping missions in East Timor, Bosnia, Kosovo, Afghanistan, Somalia, Iraq (Nasiriyah), Lebanon, Mali and Central African Republic. Portugal also conducted several independent unilateral military operations abroad, as were the cases of the interventions of the Portuguese Armed Forces in Angola in 1992 and in Guinea-Bissau in 1998 with the main objectives of protecting and withdrawing of Portuguese and foreign citizens threatened by local civil conflicts. Law The Portuguese legal system is part of the civil law legal system, also called the continental family legal system. The main laws include the Constitution (1976, as amended), the Portuguese Civil Code (1966, as amended) and the Penal Code of Portugal (1982, as amended). Other relevant laws are the Commercial Code (1888, as amended) and the Civil Procedure Code (1961, as amended). The supreme national courts are the Supreme Court of Justice and the Constitutional Court. The Public Ministry, headed by the Attorney General of the Republic, constitutes the independent body of public prosecutors. Portuguese laws were applied in the former colonies and territories and continue to be major influences for those countries. Portugal was the first country in the world to abolish life imprisonment (in 1884) and was one of the first countries to abolish the death penalty. Maximum jail sentences are limited to 25 years. Portugal is also known for having decriminalized the usage of all common drugs in 2001, the first country in the world to do so. Portugal decriminalized possession of effectively all drugs that are still illegal in other developed nations including cannabis, cocaine, heroin, and LSD. While possession is legal, trafficking and possession of more than "10 days worth of personal use" are still punishable by jail time and fines. People caught with small amounts of any drug are given the choice to go to a rehab facility, and may refuse treatment without consequences. Despite criticism from other European nations, who stated Portugal's drug consumption would tremendously increase, overall drug use has declined along with the number of HIV infection cases, which had dropped 50 percent by 2009. Drug use among 16- to 18-year-olds also declined, however the use of marijuana rose only slightly among that age group. LGBTI rights have increased substantially in the past years. On 27 August 2003, Portugal added the anti-discrimination employment law on the basis of sexual orientation. At 24 July 2004, sexual orientation was added to the Constitution as part of the protected from discrimination characteristics. On 31 May 2010, Portugal became the sixth country in Europe and the eighth country in the world to legally recognize same-sex marriage at the national level. The law came into force on 5 June 2010. Same-sex adoption has been allowed since 1 March 2016 as is female same-sex couple access to medically assisted reproduction since 13 May 2016. This bill was adopted by the Parliament and signed by President Marcelo Rebelo de Sousa. As of January 2017 the New Law of Gender Identity, simplified the legal process of gender and name change for transgender people, making it easier for minors to change their sex marker in legal documents. At August 2018, the right to gender identity and gender expression self-determination became protected, intersex minors became protected by law from unnecessary medical procedures "until the minor gender identity manifests" and the right of protection from discrimination on the basis of sex characteristics also became protected by the same law. Law enforcement Portugal's main police organizations are the Guarda Nacional Republicana – GNR (National Republican Guard), a gendarmerie; the Polícia de Segurança Pública – PSP (Public Security Police), a civilian police force who work in urban areas; and the Polícia Judiciária – PJ (Judicial Police), a highly specialized criminal investigation police that is overseen by the Public Ministry. Correctional services Portugal has 49 correctional facilities in total run by the Ministry of Justice. They include 17 central prisons, 4 special prisons, 27 regional prisons, and 1 'Cadeia de Apoio'(Support Detention Centre). , their current prison population is about 11,234 inmates, which comes to about 0.11% of their entire population. Their incarceration rate has been on the rise since 2010, with a 15% increase over the past eight years. Administrative divisions Administratively, Portugal is divided into 308 municipalities (), which after a reform in 2013 are subdivided into 3,092 civil parishes (). Operationally, the municipality and civil parish, along with the national government, are the only legally local administrative units identified by the government of Portugal (for example, cities, towns or villages have no standing in law, although may be used as catchment for the defining services). For statistical purposes the Portuguese government also identifies Nomenclature of Territorial Units for Statistics (NUTS), inter-municipal communities and informally, the district system, used until European integration (and being phased-out by the national government). Continental Portugal is agglomerated into 18 districts, while the archipelagos of the Azores and Madeira are governed as autonomous regions; the largest units, established since 1976, are either mainland Portugal () and the autonomous regions of Portugal (Azores and Madeira). The 18 districts of mainland Portugal are: Aveiro, Beja, Braga, Bragança, Castelo Branco, Coimbra, Évora, Faro, Guarda, Leiria, Lisbon, Portalegre, Porto, Santarém, Setúbal, Viana do Castelo, Vila Real and Viseu – each district takes the name of the district capital. Within the European Union NUTS system, Portugal is divided into seven regions: the Azores, Alentejo, Algarve, Centro, Lisboa, Madeira and Norte, and with the exception of the Azores and Madeira, NUTS areas are subdivided into 28 subregions. Government finance The Portuguese government is heavily indebted, and received a 78-billion-euro bailout from the European Union and the International Monetary Fund in May 2011. The ratio of Portugal's debt to its overall economy, was 107 per cent when it received the bailout. As part of the deal, the country agreed to cut its budget deficit from 9.8 per cent of GDP in 2010 to 5.9 per cent in 2011, 4.5 per cent in 2012 and 3 per cent in 2013. After the bailout was announced, the Portuguese government headed by Pedro Passos Coelho managed to implement measures with the intention of improving the state's financial situation, including tax hikes, a freeze of civil service-related lower-wages and cuts of higher-wages by 14.3%, on top of the government's spending cuts. The Portuguese government also agreed to eliminate its golden share in Portugal Telecom which gave it veto power over vital decisions. In 2012, all public servants had already seen an average wage cut of 20% relative to their 2010 baseline, with cuts reaching 25% for those earning more than 1,500 euro per month. The IMF, the European Commission (EC) and the European Central Bank (ECB) said in September 2012 that Portugal's debt would peak at 124 per cent of gross domestic product in 2014. The IMF previously said in July 2012 that Portugal's debt would peak at about 118.5 per cent of GDP in 2013. In September 2013, the Portuguese Government reviewed again the public debt of Portugal for 2013 to 127.8 per cent, after a peak of 130.9 per cent in that month. A report released in January 2011 by the Diário de Notícias and published in Portugal by Gradiva, had demonstrated that in the period between the Carnation Revolution in 1974 and 2010, the democratic Portuguese Republic governments encouraged over-expenditure and investment bubbles through unclear Public–private partnerships and funding of numerous ineffective and unnecessary external consultancy and advisory of committees and firms. This allowed considerable slippage in state-managed public works and inflated top management and head officer bonuses and wages. Persistent and lasting recruitment policies boosted the number of redundant public servants. Risky credit, public debt creation, and European structural and cohesion funds were mismanaged across almost four decades. Two Portuguese banks, Banco Português de Negócios (BPN) and Banco Privado Português (BPP), had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications – Portugal's then President, Cavaco Silva and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. On grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general. Economy Portugal is a developed and a high-income country, with a GDP per capita of 77% of the EU28 average in 2017 (increasing from 75% in 2012) and a HDI of 0.850 (the 40th highest) in 2018. By the end of 2018, Portugal's GDP (PPP) was $32,554 per capita, according to OECD's report. The national currency of Portugal is the euro (€), which replaced the Portuguese Escudo, and the country was one of the original member states of the eurozone. Portugal's central bank is the Banco de Portugal, an integral part of the European System of Central Banks. Most industries, businesses and financial institutions are concentrated in the Lisbon and Porto metropolitan areas – the Setúbal, Aveiro, Braga, Coimbra, Leiria and Faro districts are the biggest economic centres outside these two main areas. According to World Travel Awards, Portugal was Europe's Leading Golf Destination in 2012 and 2013. Since the Carnation Revolution of 1974, which culminated in the end of one of Portugal's most notable phases of economic expansion (that started in the 1960s), a significant change has occurred in the nation's annual economic growth. After the turmoil of the 1974 revolution and the PREC period, Portugal tried to adapt to a changing modern global economy, a process that continues in 2013. Since the 1990s, Portugal's public consumption-based economic development model has been slowly changing to a system that is focused on exports, private investment and the development of the high-tech sector. Consequently, business services have overtaken more traditional industries such as textiles, clothing, footwear and cork (Portugal is the world's leading cork producer), wood products and beverages. In the second decade of the 21st century, the Portuguese economy suffered its most severe recession since the 1970s, resulting in the country having to be bailed out by the European Commission, European Central Bank and International Monetary Fund (IMF). The bailout, agreed to in 2011, required Portugal to enter into a range of austerity measures in exchange for funding support of €78,000,000,000. In May 2014, the country exited the bailout but reaffirmed its commitment to maintaining its reformist momentum. At the time of exiting the bailout, the economy had contracted by 0.7% in the first quarter of 2014; however, unemployment, while still high, had fallen to 15.3%. The average salary in Portugal is €910 per month, excluding self-employed individuals and the minimum wage, which is regulated by law, is €705 per month (paid 14 times per annum) as of 2022. The Global Competitiveness Report for 2019, published by the World Economic Forum, placed Portugal on the 34th position on the economic index. The Economist Intelligence Unit's quality of life index placed Portugal as the country with the 19th-best quality of life in the world for 2005, ahead of other economically and technologically advanced countries like France, Germany, the United Kingdom and South Korea, but 9 places behind its sole neighbour, Spain. This is despite the fact that Portugal remains as one of the countries with the lowest per capita GDP in Western Europe. Major state-owned companies include: Águas de Portugal (water), Caixa Geral de Depósitos (banking), Comboios de Portugal (railways), Companhia das Lezírias (agriculture) and RTP (media). Some former state-owned entities are managed by state-run holding company Parpública, which is a shareholder of several public and private companies. Among former state-owned companies recently privatized are: CTT (postal service) and ANA (airports). Companies listed on Euronext Lisbon stock exchange like EDP, Galp, Jerónimo Martins, Mota-Engil, Novabase, Semapa, Portucel Soporcel, Portugal Telecom and Sonae, are amongst the largest corporations of Portugal by number of employees, net income or international market share. The Euronext Lisbon is the major stock exchange of Portugal and is part of the NYSE Euronext, the first global stock exchange. The PSI-20 is Portugal's most selective and widely known stock index. The International Monetary Fund issued an update report on the economy of Portugal in late-June 2017 with a strong near-term outlook and an increase in investments and exports over previous years. Because of a surplus in 2016, the country was no longer bound by the Excessive Deficit Procedure which had been implemented during an earlier financial crisis. The banking system was more stable, although there were still non-performing loans and corporate debt. The IMF recommended working on solving these problems for Portugal to be able to attract more private investment. "Sustained strong growth, together with continued public debt reduction, would reduce vulnerabilities arising from high indebtedness, particularly when monetary accommodation is reduced." The OECD economic reports since 2018 show recovery, albeit slow; and Portugal's growth prospects continue positive for 2020. Primary sector Agriculture in Portugal is based on small to medium-sized family-owned dispersed units. However, the sector also includes larger scale intensive farming export-oriented agrobusinesses backed by companies (like Grupo RAR's Vitacress, Sovena, Lactogal, Vale da Rosa, Companhia das Lezírias and Valouro). The country produces a wide variety of crops and livestock products, including: tomatoes, citrus, green vegetables, rice, wheat, barley, maize, olives, oilseeds, nuts, cherries, bilberry, table grapes, edible mushrooms, dairy products, poultry and beef. According to FAO, Portugal is the top producer of cork and carob in the world, accounting to about 50% and 30% of world production respectively. It is also the third largest exporter of chestnut and the third largest European producer of pulp. Portugal is among the top ten largest olive oil producers in the world and is the fourth biggest exporter. The country is also one of the world's largest exporters of wine, being reputed for its fine wines. Forestry has also played an important economic role among the rural communities and industry (namely paper industry that includes Portucel Soporcel Group, engineered wood that includes Sonae Indústria, and furniture that includes several manufacturing plants in and around Paços de Ferreira, the core of Portugal's major industrial operations of IKEA). In 2001, the gross agricultural product accounted for 4% of the national GDP. Traditionally a sea power, Portugal has had a strong tradition in the Portuguese fishing sector and is one of the countries with the highest fish consumption per capita. The main landing sites in Portugal (including Azores and Madeira), according to total landings in weight by year, are the harbours of Matosinhos, Peniche, Olhão, Sesimbra, Figueira da Foz, Sines, Portimão and Madeira. Portuguese-processed fish products are exported through several companies, under a number of different brands and registered trademarks, such as Ramirez, the world's oldest active canned fish producer. Portugal is a significant European minerals producer and is ranked among Europe's leading copper producers. The nation is also a notable producer of tin, tungsten and uranium. However, the country lacks the potential to conduct hydrocarbon exploration and aluminium, a limitation that has hindered the development of Portugal's mining and metallurgy sectors. Although the country has vast iron and coal reserves – mainly in the north – after the 1974 revolution and the consequent economic globalization, low competitiveness forced a decrease in the extraction activity for these minerals. The Panasqueira and Neves-Corvo mines are among the most recognized Portuguese mines that are still in operation. Portugal is rich in its lithium subsoil, which is especially concentrated in the districts of Guarda, Viseu, Vila Real and Viana do Castelo, while most of the country's lithium comes from the Gonçalo aplite-pegmatite field. The largest lithium mine in Europe is operated by Grupo Mota, Felmica, in the Guarda region, which is estimated to have reserves for 30 years of production. It has 5 more deposits in its possession. Savannah Resources in May 2018 announced a 52% increase in the estimated lithium resources at the Mina do Barroso Lithium Project in northern Portugal, saying the country could become the first European supplier of spodumene, a lithium-bearing mineral. The company said the estimated mineral resources at the mine now stood at 14 million tonnes. Lithium prices have risen in expectation of growing demand for the mineral, which is used in batteries for electric vehicles and for storing electricity from the power grid. Europe consumes more than 20 per cent of the global supply of battery-grade lithium but currently has to import all its supplies of the mineral. W Resources stated in 2018 that it had started a new drilling campaign at its São Martinho gold project in Portugal. The so-called reverse circulation drilling programme included 15 holes with around 2,000 metres of total drilling. The objective is to extend resources by integrating the data from 2016 drilling results with the expansion expected with the ongoing campaign. Secondary sector Industry is diversified, ranging from automotive (Volkswagen Autoeuropa and Peugeot Citroën) and bicycles, aerospace (Embraer and OGMA), electronics and textiles, to food, chemicals, cement and wood pulp. Volkswagen Group's AutoEuropa motor vehicle assembly plant in Palmela is among the largest foreign direct investment projects in Portugal. Modern non-traditional technology-based industries, such as aerospace, biotechnology and information technology, have been developed in several locations across the country. Alverca, Évora and Ponte de Sor are the main centres of the Portuguese aerospace industry, which is led by Brazil-based company Embraer and the Portuguese company OGMA. Following the turn of the 21st century, many major biotechnology and information technology industries have been founded, and are concentrated in the metropolitan areas of Lisbon, Porto, Braga, Coimbra and Aveiro. Tertiary sector The banking and insurance sectors performed well until the financial crisis of 2007–2008, and this partly reflected a rapid deepening of the market in Portugal. While sensitive to various types of market and underwriting risks, it has been estimated that overall both the life and non-life sectors will be able to withstand a number of severe shocks, even though the impact on individual insurers varies widely. Travel and tourism continue to be extremely important for Portugal. It has been necessary for the country to focus upon its niche attractions, such as health, nature and rural tourism, to stay ahead of its competitors. Portugal is among the top 20 most-visited countries in the world, receiving an average of 20,000,000 foreign tourists each year. In 2014, Portugal was elected The Best European Country by USA Today. In 2017, Portugal was elected both Europe's Leading Destination and in 2018 and 2019, World's Leading Destination Tourist hotspots in Portugal are: Lisbon, Cascais, Fatima, Algarve, Madeira, Porto and Coimbra. Lisbon attracts the sixteenth-most tourists among European cities (with seven million tourists occupying the city's hotels in 2006). Notable luxury destinations include the Portuguese Riviera and the Comporta Coast. Also, between 5–6 million religious pilgrims visit Fatima each year, where apparitions of the Virgin Mary to three shepherd children allegedly took place in 1917. The Sanctuary of Our Lady of Fatima is one of the largest Roman Catholic shrines in the world. The Portuguese government continues to promote and develop new tourist destinations, such as the Douro Valley, the island of Porto Santo, and Alentejo. The legend of the Rooster of Barcelos tells the story of a dead rooster's miraculous intervention in proving the innocence of a man who had been falsely accused and sentenced to death. The story is associated with the 17th-century calvary that is part of the collection of the Archaeological Museum located in Paço dos Condes, a gothic-style palace in Barcelos, a city in northwest Portugal. The Rooster of Barcelos is bought by thousands of tourists as a national souvenir. On 30 November 2016, the United Nations added the Portuguese tradition of making black pottery to the UNESCO Heritage Protection List. On 7 December 2017, the United Nations added the Bonecos de Estremoz – Toys of Estremoz tradition as an UNESCO Intangible Cultural Heritage of Humankind. Quaternary sector Scientific and technological research activities in Portugal are mainly conducted within a network of R&D units belonging to public universities and state-managed autonomous research institutions like the INETI – Instituto Nacional de Engenharia, Tecnologia e Inovação and the INRB – Instituto Nacional dos Recursos Biológicos. The funding and management of this research system is mainly conducted under the authority of the Ministry of Science, Technology and Higher Education (MCTES) and the MCTES's Fundação para a Ciência e Tecnologia (FCT). The largest R&D units of the public universities by volume of research grants and peer-reviewed publications, include biosciences research institutions like the Instituto de Medicina Molecular, the Centre for Neuroscience and Cell Biology, the IPATIMUP, the Instituto de Biologia Molecular e Celular and the Abel Salazar Biomedical Sciences Institute. Among the largest non-state-run research institutions in Portugal are the Instituto Gulbenkian de Ciência and the Champalimaud Foundation, a neuroscience and oncology research centre which awards every year one of the highest monetary prizes of any science prize in the world. A number of both national and multinational high-tech and industrial companies, are also responsible for research and development projects. One of the oldest learned societies of Portugal is the Sciences Academy of Lisbon, founded in 1779. Iberian bilateral state-supported research efforts include the International Iberian Nanotechnology Laboratory and the Ibercivis distributed computing platform, which are joint research programmes of both Portugal and Spain. Portugal is a member of several pan-European scientific organizations. These include the European Space Agency (ESA), the European Laboratory for Particle Physics (CERN), ITER, and the European Southern Observatory (ESO). Portugal has the largest aquarium in Europe, the Lisbon Oceanarium, and the Portuguese have several other notable organizations focused on science-related exhibits and divulgation, like the state agency Ciência Viva, a programme of the Portuguese Ministry of Science and Technology to the promotion of a scientific and technological culture among the Portuguese population, the Science Museum of the University of Coimbra, the National Museum of Natural History at the University of Lisbon, and the Visionarium. With the emergence and growth of several science parks throughout the world that helped create many thousands of scientific, technological and knowledge-based businesses, Portugal started to develop several science parks across the country. These include the Taguspark (in Oeiras), the Coimbra iParque (in Coimbra), the biocant (in Cantanhede), the Madeira Tecnopolo (in Funchal), Sines Tecnopolo (in Sines), Tecmaia (in Maia) and Parkurbis (in Covilhã). Companies locate in the Portuguese science parks to take advantage of a variety of services ranging from financial and legal advice through to marketing and technological support. Egas Moniz, a Portuguese physician who developed the cerebral angiography and leucotomy, received in 1949 the Nobel Prize in Physiology or Medicine – he is the first Portuguese recipient of a Nobel Prize and the only in the sciences. The European Innovation Scoreboard 2011, placed Portugal-based innovation in the 15th position, with an impressive increase in innovation expenditure and output. Portugal was ranked 31st in the Global Innovation Index in 2020, up from 32nd in 2019. Transport By the early-1970s, Portugal's fast economic growth with increasing consumption and purchase of new automobiles set the priority for improvements in transportation. Again in the 1990s, after joining the European Economic Community, the country built many new motorways. Today, the country has a road network, of which almost are part of system of 44 motorways. Opened in 1944, the first motorway (which linked Lisbon to the National Stadium) was an innovative project that made Portugal one of the first countries in the world to establish a motorway (this roadway eventually became the Lisbon-Cascais highway, or A5). Although a few other tracts were created (around 1960 and 1970), it was only after the beginning of the 1980s that large-scale motorway construction was implemented. In 1972, Brisa, the highway concessionaire, was founded to handle the management of many of the region's motorways. On many highways, a toll needs to be paid (see Via Verde). Vasco da Gama bridge is the longest bridge in Europe at 12.345 km. Continental Portugal's territory is serviced by four international airports located near the principal cities of Lisbon, Porto, Faro and Beja. Lisbon's geographical position makes it a stopover for many foreign airlines at several airports within the country. The primary flag-carrier is TAP Air Portugal, although many other domestic airlines provide services within and without the country. The government decided to build a new airport outside Lisbon, in Alcochete, to replace Lisbon Portela Airport, though this plan has been suspended due to austerity measures. Currently, the most important airports are in Lisbon, Porto, Faro, Funchal (Madeira), and Ponta Delgada (Azores), managed by the national airport authority group ANA – Aeroportos de Portugal. One other important airport is the Aeroporto Internacional das Lajes on the island of Terceira in the Azores. This airport serves as one of two international airports serving countries outside the European Union for all nine islands of the Azores. It also serves as a military air base for the United States Air Force. The base remains in use to the present day. A national railway system that extends throughout the country and into Spain, is supported and administered by Comboios de Portugal (CP). Rail transport of passengers and goods is derived using the of railway lines currently in service, of which are electrified and about allow train speeds greater than . The railway network is managed by Infraestruturas de Portugal while the transport of passengers and goods are the responsibility of CP, both public companies. In 2006, the CP carried 133,000,000 passengers and of goods. The major seaports are located in Sines, Lisbon, Leixões, Setúbal, Aveiro, Figueira da Foz, and Faro. The two largest metropolitan areas have subway systems: Lisbon Metro and Metro Sul do Tejo in the Lisbon metropolitan area and Porto Metro in the Porto Metropolitan Area, each with more than of lines. In Portugal, Lisbon tram services have been supplied by the Companhia de Carris de Ferro de Lisboa (Carris), for over a century. In Porto, a tram network, of which only a tourist line on the shores of the Douro remains, began construction on 12 September 1895 (a first for the Iberian Peninsula). All major cities and towns have their own local urban transport network, as well as taxi services. Energy Portugal has considerable resources of wind and river power, the two most cost-effective renewable energy sources. Since the turn of the 21st century, there has been a trend towards the development of a renewable resource industry and reduction of both consumption and use of fossil fuels. In 2006, the world's largest solar power plant at that date, the Moura Photovoltaic Power Station, began operating near Moura, in the south, while the world's first commercial wave power farm, the Aguçadoura Wave Farm, opened in the Norte region (2008). By the end of 2006, 66% of the country's electrical production was from coal and fuel power plants, while 29% were derived from hydroelectric dams, and 6% by wind energy. In 2008, renewable energy resources were producing 43% of the nation's consumption of electricity, even as hydroelectric production decreased with severe droughts. As of June 2010, electricity exports had outnumbered imports. In the period between January and May 2010, 70% of the national production of energy came from renewable sources. Portugal's national energy transmission company, |
also must be connected to a power amplifier and speaker to produce sound (however, most digital pianos have a built-in amp and speaker). Alternatively, a person can practice with headphones to avoid disturbing others. Digital pianos can include sustain pedals, weighted or semi-weighted keys, multiple voice options (e.g., sampled or synthesized imitations of electric piano, Hammond organ, violin, etc.), and MIDI interfaces. MIDI inputs and outputs connect a digital piano to other electronic instruments or musical devices. For example, a digital piano's MIDI out signal could be connected by a patch cord to a synth module, which would allow the performer to use the keyboard of the digital piano to play modern synthesizer sounds. Early digital pianos tended to lack a full set of pedals but the synthesis software of later models such as the Yamaha Clavinova series synthesised the sympathetic vibration of the other strings (such as when the sustain pedal is depressed) and full pedal sets can now be replicated. The processing power of digital pianos has enabled highly realistic pianos using multi-gigabyte piano sample sets with as many as ninety recordings, each lasting many seconds, for each key under different conditions (e.g., there are samples of each note being struck softly, loudly, with a sharp attack, etc.). Additional samples emulate sympathetic resonance of the strings when the sustain pedal is depressed, key release, the drop of the dampers, and simulations of techniques such as re-pedalling. Digital, MIDI-equipped, pianos can output a stream of MIDI data, or record and play via a CD ROM or USB flash drive using MIDI format files, similar in concept to a pianola. The MIDI file records the physics of a note rather than its resulting sound and recreates the sounds from its physical properties (e.g., which note was struck and with what velocity). Computer based software, such as Modartt's 2006 Pianoteq, can be used to manipulate the MIDI stream in real time or subsequently to edit it. This type of software may use no samples but synthesize a sound based on aspects of the physics that went into the creation of a played note. Hybrid instruments In the 2000s, some pianos include an acoustic grand piano or upright piano combined with MIDI electronic features. Such a piano can be played acoustically, or the keyboard can be used as a MIDI controller, which can trigger a synthesizer module or music sampler. Some electronic feature-equipped pianos such as the Yamaha Disklavier electronic player piano, introduced in 1987, are outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of the keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF). On playback, the solenoids move the keys and pedals and thus reproduce the original performance. Modern Disklaviers typically include an array of electronic features, such as a built-in tone generator for playing back MIDI accompaniment tracks, speakers, MIDI connectivity that supports communication with computing devices and external MIDI instruments, additional ports for audio and SMPTE input/output (I/O), and Internet connectivity. Disklaviers have been manufactured in the form of upright, baby grand, and grand piano styles (including a nine-foot concert grand). Reproducing systems have ranged from relatively simple, playback-only models to professional models that can record performance data at resolutions that exceed the limits of normal MIDI data. The unit mounted under the keyboard of the piano can play MIDI or audio software on its CD. Construction and components Pianos can have over 12,000 individual parts, supporting six functional features: keyboard, hammers, dampers, bridge, soundboard, and strings. Many parts of a piano are made of materials selected for strength and longevity. This is especially true of the outer rim. It is most commonly made of hardwood, typically hard maple or beech, and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin, the purpose of a sturdy rim is so that, "... the vibrational energy will stay as much as possible in the soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." Hardwood rims are commonly made by laminating thin, hence flexible, strips of hardwood, bending them to the desired shape immediately after the application of glue. The bent plywood system was developed by C.F. Theodore Steinway in 1880 to reduce manufacturing time and costs. Previously, the rim was constructed from several pieces of solid wood, joined and veneered, and European makers used this method well into the 20th century. A modern exception, Bösendorfer, the Austrian manufacturer of high-quality pianos, constructs their inner rims from solid spruce, the same wood that the soundboard is made from, which is notched to allow it to bend; rather than isolating the rim from vibration, their "resonance case principle" allows the framework to resonate more freely with the soundboard, creating additional coloration and complexity of the overall sound. The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure, and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy. Even a small upright can weigh , and the Steinway concert grand (Model D) weighs . The largest piano available on the general market, the Fazioli F308, weighs . The pinblock, which holds the tuning pins in place, is another area where toughness is important. It is made of hardwood (typically hard maple or beech), and is laminated for strength, stability and longevity. Piano strings (also called piano wire), which must endure years of extreme tension and hard blows, are made of high carbon steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of a piano are made of a steel core wrapped with copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble. The plate (harp), or metal frame, of a piano is usually made of cast iron. A massive plate is advantageous. Since the strings vibrate from the plate at both ends, an insufficiently massive plate would absorb too much of the vibrational energy that should go through the bridge to the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use, is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling. Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during the 1940s. Aluminum piano plates were not widely accepted, and were discontinued. The numerous parts of a piano action are generally made from hardwood, such as maple, beech, and hornbeam; however, since World War II, makers have also incorporated plastics. Early plastics used in some pianos in the late 1940s and 1950s, proved disastrous when they lost strength after a few decades of use. Beginning in 1961, the New York branch of the Steinway firm incorporated Teflon, a synthetic material developed by DuPont, for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time; Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently, the Kawai firm built pianos with action parts made of more modern materials such as carbon fiber reinforced plastic, and the piano parts manufacturer Wessell, Nickel and Gross has launched a new line of carefully engineered composite parts. Thus far these parts have performed reasonably, but it will take decades to know if they equal the longevity of wood. In all but the lowest quality pianos the soundboard is made of solid spruce (that is, spruce boards glued together along the side grain). Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn, defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This is the identical material that is used in quality acoustic guitar soundboards. Cheap pianos often have plywood soundboards. The design of the piano hammers requires having the hammer felt be soft enough so that it will not create loud, very high harmonics that a hard hammer will cause. The hammer must be lightweight enough to move swiftly when a key is pressed; yet at the same time, it must be strong enough so that it can hit strings hard when the player strikes the keys forcefully for fortissimo playing or sforzando accents. Keyboard In the early years of piano construction, keys were commonly made from sugar pine. In the 2010s, they are usually made of spruce or basswood. Spruce is typically used in high-quality pianos. Black keys were traditionally made of ebony, and the white keys were covered with strips of ivory. However, since ivory-yielding species are now endangered and protected by treaty, or are illegal in some countries, makers use plastics almost exclusively. Also, ivory tends to chip more easily than plastic. Legal ivory can still be obtained in limited quantities. Yamaha developed a plastic called Ivorite intended to mimic the look and feel of ivory; other manufacturers have done likewise. Almost every modern piano has 52 white keys and 36 black keys for a total of 88 keys (seven octaves plus a minor third, from A0 to C8). Many older pianos only have 85 keys (seven octaves from A0 to A7). Some piano manufacturers have extended the range further in one or both directions. For example, the Imperial Bösendorfer has nine extra keys at the bass end, giving a total of 97 keys and an eight octave range. These extra keys are sometimes hidden under a small hinged lid that can cover the keys to prevent visual disorientation for pianists unfamiliar with the extra keys, or the colours of the extra white keys are reversed (black instead of white). More recently, Australian manufacturer Stuart & Sons created a piano with 108 keys, going from C0 to B8, covering nine full octaves. The extra keys are the same as the other keys in appearance. The extra keys are added primarily for increased resonance from the associated strings; that is, they vibrate sympathetically with other strings whenever the damper pedal is depressed and thus give a fuller tone. Only a very small number of works composed for piano actually use these notes. Toy piano company Schoenhut manufactures grands and uprights with only 44 or 49 keys and a shorter distance between the keyboard and the pedals. These are true pianos with working mechanisms and strings. A rare variant of the piano called the Emánuel Moór Pianoforte has double keyboards, one lying above the other. It was invented by Hungarian composer and pianist, Emánuel Moór (19 February 1863 – 20 October 1931). The lower keyboard has the usual 88 keys, whilst the upper keyboard has 76 keys. When the upper keyboard is played, an internal mechanism pulls down the corresponding key on the lower keyboard, but an octave higher. This lets a pianist reach two octaves with one hand, impossible on a conventional piano. Due to its double keyboard, musical works that were originally created for double-manual harpsichord, such as the Goldberg Variations by Bach, become much easier to play, since playing on a conventional single keyboard piano involves complex and hand-tangling cross-hand movements. The design also features a special fourth pedal that couples the lower and upper keyboard, so when playing on the lower keyboard the note one octave higher also plays. Only about 60 Emánuel Moór Pianofortes were made, mostly by Bösendorfer. Other piano manufacturers, such as Bechstein, Chickering, and Steinway & Sons, also manufactured a few. Pianos have been built with alternative keyboard systems, e.g., the Jankó keyboard. Pedals Pianos have had pedals, or some close equivalent, since the earliest days. (In the 18th century, some pianos used levers pressed upward by the player's knee instead of pedals.) Most grand pianos in the US have three pedals: the soft pedal (una corda), sostenuto, and sustain pedal (from left to right, respectively), while in Europe, the standard is two pedals: the soft pedal and the sustain pedal. Most modern upright pianos also have three pedals: soft pedal, practice pedal and sustain pedal, though older or cheaper models may lack the practice pedal. In Europe the standard for upright pianos is two pedals: the soft and the sustain pedals. The sustain pedal (or, damper pedal) is often simply called "the pedal", since it is the most frequently used. It is placed as the rightmost pedal in the group. It lifts the dampers from all keys, sustaining all played notes. In addition, it alters the overall tone by allowing all strings, including those not directly played, to reverberate. When all of the other strings on the piano can vibrate, this allows sympathetic vibration of strings that are harmonically related to the sounded pitches. For example, if the pianist plays the 440 Hz "A" note, the higher octave "A" notes will also sound sympathetically. The soft pedal or una corda pedal is placed leftmost in the row of pedals. In grand pianos it shifts the entire action/keyboard assembly to the right (a very few instruments have shifted left) so that the hammers hit two of the three strings for each note. In the earliest pianos whose unisons were bichords rather than trichords, the action shifted so that hammers hit a single string, hence the name una corda, or 'one string'. The effect is to soften the note as well as change the tone. In uprights this action is not possible; instead the pedal moves the hammers closer to the strings, allowing the hammers to strike with less kinetic energy. This produces a slightly softer sound, but no change in timbre. On grand pianos, the middle pedal is a sostenuto pedal. This pedal keeps raised any damper already raised at the moment the pedal is depressed. This makes it possible to sustain selected notes (by depressing the sostenuto pedal before those notes are released) while the player's hands are free to play additional notes (which don't sustain). This can be useful for musical passages with low bass pedal points, in which a bass note is sustained while a series of chords changes over top of it, and other otherwise tricky parts. On many upright pianos, the middle pedal is called the "practice" or celeste pedal. This drops a piece of felt between the hammers and strings, greatly muting the sounds. This pedal can be shifted while depressed, into a "locking" position. There are also non-standard variants. On some pianos (grands and verticals), the middle pedal can be a bass sustain pedal: that is, when it is depressed, the dampers lift off the strings only in the bass section. Players use this pedal to sustain a single bass note or chord over many measures, while playing the melody in the treble section. The rare transposing piano (an example of which was owned by Irving Berlin) has a middle pedal that functions as a clutch that disengages the keyboard from the mechanism, so the player can move the keyboard to the left or right with a lever. This shifts the entire piano action so the pianist can play music written in one key so that it sounds in a different key. Some piano companies have included extra pedals other than the standard two or three. On the Stuart and Sons pianos as well as the largest Fazioli piano, there is a fourth pedal to the left of the principal three. This fourth pedal works in the same way as the soft pedal of an upright piano, moving the hammers closer to the strings. The Crown and Schubert Piano Company also produced a four-pedal piano. Wing and Son of New York offered a five-pedal piano from approximately 1893 through the 1920s. There is no mention of the company past the 1930s. Labeled left to right, the pedals are Mandolin, Orchestra, Expression, Soft, and Forte (Sustain). The Orchestral pedal produced a sound similar to a tremolo feel by bouncing a set of small beads dangling against the strings, enabling the piano to mimic a mandolin, guitar, banjo, zither and harp, thus the name Orchestral. The Mandolin pedal used a similar approach, lowering a set of felt strips with metal rings in between the hammers and the strings (aka rinky-tink effect). This extended the life of the hammers when the Orch pedal was used, a good idea for practicing, and created an echo-like sound that mimicked playing in an orchestral hall. The pedalier piano, or pedal piano, is a rare type of piano that includes a pedalboard so players can use their feet to play bass register notes, as on an organ. There are two types of pedal piano. On one, the pedal board is an integral part of the instrument, using the same strings and mechanism as the manual keyboard. The other, rarer type, consists of two independent pianos (each with separate mechanics and strings) placed one above the other—one for the hands and one for the feet. This was developed primarily as a practice instrument for organists, though there is a small repertoire written specifically for the instrument. Mechanics When the key is struck, a chain reaction occurs to produce the sound. First, the key raises the "wippen" mechanism, which forces the jack against the hammer roller (or knuckle). The hammer roller then lifts the lever carrying the hammer. The key also raises the damper; and immediately after the hammer strikes the wire it falls back, allowing the wire to resonate and thus produce sound. When the key is released the damper falls back onto the strings, stopping the wire from vibrating, and thus stopping the sound. The vibrating piano strings themselves are not very loud, but their vibrations are transmitted to a large soundboard that moves air and thus converts the energy to sound. The irregular shape and off-center placement of the bridge ensure that the soundboard vibrates strongly at all frequencies. The raised damper allows the note to sound until the key (or sustain pedal) is released. There are three factors that influence the pitch of a vibrating wire. Length: All other factors the same, the shorter the wire, the higher the pitch. Mass per unit length: All other factors the same, the thinner the wire, the higher the pitch. Tension: All other factors the same, the tighter the wire, the higher the pitch. A vibrating wire subdivides itself into many parts vibrating at the same time. Each part produces a pitch of its own, called a partial. A vibrating string has one fundamental and a series of partials. The purest combination of two pitches is when one is double the frequency of the other. For a repeating wave, the velocity equals the wavelength times the frequency , On the piano string, waves reflect from both ends. The superposition of reflecting waves results in a standing wave pattern, but only for wavelengths , where is the length of the string. Therefore, the only frequencies produced on a single string are . Timbre is largely determined by the content of these harmonics. Different instruments have different harmonic content for the same pitch. A real string vibrates at harmonics that are not perfect multiples of the fundamental. This results in a little inharmonicity, which gives richness to the tone but causes significant tuning challenges throughout the compass of the instrument. Striking the piano key with greater velocity increases the amplitude of the waves and therefore the volume. From pianissimo () to fortissimo () the hammer velocity changes by almost a factor of a hundred. The hammer contact time with the string shortens from 4 milliseconds at to less than 2 ms at . If two wires adjusted to the same pitch are struck at the same time, the sound produced by one reinforces the other, and a louder combined sound of shorter duration is produced. If one wire vibrates out of synchronization with the other, they subtract from each other and produce a softer tone of longer duration. Maintenance Pianos are heavy and powerful, yet delicate instruments. Over the years, professional piano movers have developed special techniques for transporting both grands and uprights, which prevent damage to the case and to the piano's mechanical elements. Pianos need regular tuning to keep them on correct pitch. The hammers of pianos are voiced to compensate for gradual hardening of the felt, and other parts also need periodic regulation. Pianos need regular maintenance to ensure the felt hammers and key mechanisms are functioning properly. Aged and worn pianos can be rebuilt or reconditioned by piano rebuilders. Strings eventually must be replaced. Often, by replacing a great number of their parts, and adjusting them, old instruments can perform as well as new pianos. Piano tuning involves adjusting the tensions of the piano's strings with a specialized wrench, thereby aligning the intervals among their tones so that the instrument is in tune. While guitar and violin players tune their own instruments, pianists usually hire a piano tuner, a specialized technician, to tune their pianos. The piano tuner uses special tools. The meaning of the term in tune in the context of piano tuning is not simply a particular fixed set of pitches. Fine piano tuning carefully assesses the interaction among all notes of the chromatic scale, different for every piano, and thus requires slightly different pitches from any theoretical standard. Pianos are usually tuned to a modified version of the system called equal temperament (see Piano key frequencies for the theoretical piano tuning). In all systems of tuning, each pitch is derived from its relationship to a chosen fixed pitch, usually the internationally recognized standard concert pitch of A4 (the A above middle C). The term A440 refers to a widely accepted frequency of this pitch – 440 Hz. The relationship between two pitches, called an interval, is the ratio of their absolute frequencies. Two different intervals are perceived as the same when the pairs of pitches involved share the same frequency ratio. The easiest intervals to identify, and the easiest intervals to tune, are those that are just, meaning they have a simple whole-number ratio. The term temperament refers to a tuning system that tempers the just intervals (usually the perfect fifth, which has the ratio 3:2) to satisfy another mathematical property; in equal temperament, a fifth is tempered by narrowing it slightly, achieved by flattening its upper pitch slightly, or raising its lower pitch slightly. A temperament system is also known as a set of "bearings". Tempering an interval causes it to beat, which is a fluctuation in perceived sound intensity due to interference between close (but unequal) pitches. The rate of beating is equal to the frequency differences of any harmonics that are present for both pitches and that coincide or nearly coincide. Piano tuners have to use their ear to "stretch" the tuning of a piano to make it sound in tune. This involves tuning the highest-pitched strings slightly higher and the lowest-pitched strings slightly lower than what a mathematical frequency table (in which octaves are derived by doubling the frequency) would suggest. Playing and technique As with any other musical instrument, the piano may be played from written music, by ear, or through improvisation. While some folk and blues pianists were self-taught, in Classical and jazz, there are well-established piano teaching systems and institutions, including pre-college graded examinations, university, college and music conservatory diplomas and degrees, ranging from the B.Mus. and M.Mus. to the Doctor of Musical Arts in piano. Piano technique evolved during the transition from harpsichord and clavichord to fortepiano playing, and continued through the development of the modern piano. Changes in musical styles and audience preferences over the 19th and 20th century, as well as the emergence of virtuoso performers, contributed to this evolution and to the growth of distinct approaches or schools of piano playing. Although technique is often viewed as only the physical execution of a musical idea, many pedagogues and performers stress the interrelatedness of the physical and mental or emotional aspects of piano playing. Well-known approaches to piano technique include those by Dorothy Taubman, Edna Golandsky, Fred Karpoff, Charles-Louis Hanon and Otto Ortmann. Performance styles Many classical music composers, including Haydn, Mozart, and Beethoven, composed for the fortepiano, a rather different instrument than the modern piano. Even composers of the Romantic movement, like Franz Liszt, Frédéric Chopin, Clara and Robert Schumann, Fanny and Felix Mendelssohn, and Johannes Brahms, wrote for pianos substantially different from 2010-era modern pianos. Contemporary musicians may adjust their interpretation of historical compositions from the 1600s to the 1800s to account for sound quality differences between old and new instruments or to changing performance practice. Starting in Beethoven's later career, the fortepiano evolved into an instrument more like the modern piano of the 2000s. Modern pianos were in wide use by the late 19th century. They featured an octave range larger than the earlier fortepiano instrument, adding around 30 more keys to the instrument, which extended the deep bass range and the high treble range. Factory mass production of upright pianos made them more affordable for a larger number of middle-class people. They appeared in music halls and pubs during the 19th century, providing entertainment through a piano soloist, or in combination with a small dance band. Just as harpsichordists had accompanied singers or dancers performing on stage, or playing for dances, pianists took up this role in the late 1700s and in the following centuries. During the 19th century, American musicians playing for working-class audiences in small pubs and bars, particularly African-American composers, developed new musical genres based on the modern piano. Ragtime music, popularized by composers such as Scott Joplin, reached a broader audience by 1900. The popularity of ragtime music was quickly succeeded by Jazz piano. New techniques and rhythms were invented for the piano, including ostinato for boogie-woogie, and Shearing voicing. George Gershwin's Rhapsody in Blue broke new musical ground by combining American jazz piano with symphonic sounds. Comping, a technique for accompanying jazz vocalists on piano, was exemplified by Duke Ellington's technique. Honky-tonk music, featuring yet another style of piano rhythm, became popular during the same era. Bebop techniques grew out of jazz, with leading composer-pianists such as Thelonious Monk and Bud Powell. In the late 20th century, Bill Evans composed pieces combining classical techniques with his jazz experimentation. In the 1970s, Herbie Hancock was one of the first jazz composer-pianists to find mainstream popularity working with newer urban music techniques such as jazz-funk and jazz-rock. Pianos have also been used prominently in rock and roll and rock music by performers such as Jerry Lee Lewis, Little Richard, Keith Emerson (Emerson, Lake & Palmer), Elton John, Ben Folds, Billy Joel, Nicky Hopkins, and Tori Amos, to name a few. Modernist styles of music have also appealed to composers writing for the modern grand piano, including John Cage and Philip Glass. Role The piano is a crucial instrument in Western classical music, jazz, blues, rock, folk music, and many other Western musical genres. Pianos are used in soloing or melodic roles and as accompaniment instruments. As well, pianos can be played alone, with a voice or other instrument, in small groups (bands and chamber music ensembles) and large ensembles (big band or orchestra). A large number of composers and songwriters are proficient pianists because the piano keyboard offers an effective means of experimenting with complex melodic and harmonic interplay of chords and trying out multiple, independent melody lines that are played at the same time. Pianos are used by composers doing film and television scoring, as the large range permits composers to try out melodies and bass lines, even if the music will be orchestrated for other instruments. Bandleaders and choir conductors often learn the piano, as it is an excellent instrument for learning new pieces and songs to lead in performance. Many conductors are trained in piano, because it allows them to play parts of the symphonies they are conducting (using a piano reduction or doing a reduction from the full score), so that they can develop their interpretation. The piano is an essential tool in music education in elementary and secondary schools, and universities and colleges. Most music classrooms and many practice rooms have a piano. Pianos are used to help teach music theory, music history and music appreciation classes, and even non-pianist music professors or instructors may have a piano in their office.

Types Modern pianos have two basic configurations, the grand piano and the upright piano, with various styles of each. There are also specialized and novelty pianos, electric pianos based on electromechanical designs, electronic pianos that synthesize piano-like tones using oscillators, and digital pianos using digital samples of acoustic piano sounds. Grand In grand pianos the frame and strings are horizontal, with the strings extending away from the keyboard. The action lies beneath the strings, and uses gravity as its means of return to a state of rest. Grand pianos range in length from approximately to . Some of the lengths have been given more-or-less customary names, which vary from time to time and place to place, but might include: Baby grand – around Parlor grand or boudoir grand – Concert grand – between ) All else being equal, longer pianos with longer strings have larger, richer sound and lower inharmonicity of the strings. Inharmonicity is the degree to which the frequencies of overtones (known as partials or harmonics) sound sharp relative to whole multiples of the fundamental frequency. This results from the piano's considerable string stiffness; as a struck string decays its harmonics vibrate, not from their termination, but from a point very slightly toward the center (or more flexible part) of the string. The higher the partial, the further sharp it runs. Pianos with shorter and thicker string (i.e., small pianos with short string scales) have more inharmonicity. The greater the inharmonicity, the more the ear perceives it as harshness of tone. The inharmonicity of piano strings requires that octaves be stretched, or tuned to a lower octave's corresponding sharp overtone rather than to a theoretically correct octave. If octaves are not stretched, single octaves sound in tune, but double—and notably triple—octaves are unacceptably narrow. Stretching a small piano's octaves to match its inherent inharmonicity level creates an imbalance among all the instrument's intervallic relationships. In a concert grand, however, the octave "stretch" retains harmonic balance, even when aligning treble notes to a harmonic produced from three octaves below. This lets close and widespread octaves sound pure, and produces virtually beatless perfect fifths. This gives the concert grand a brilliant, singing and sustaining tone quality—one of the principal reasons that full-size grands are used in the concert hall. Smaller grands satisfy the space and cost needs of domestic use; as well, they are used in some small teaching studios and smaller performance venues. Upright Upright pianos, also called vertical pianos, are more compact due to the vertical structure of the frame and strings. The mechanical action structure of the upright piano was invented in London, England in 1826 by Robert Wornum, and upright models became the most popular model. Upright pianos took less space than a grand piano, and as such they were a better size for use in private homes for domestic music-making and practice. The hammers move horizontally, and return to their resting position via springs, which are susceptible to degradation. Upright pianos with unusually tall frames and long strings were sometimes marketed as upright grand pianos, but that label is misleading. Some authors classify modern pianos according to their height and to modifications of the action that are necessary to accommodate the height. Upright pianos are generally less expensive than grand pianos. Upright pianos are widely used in churches, community centers, schools, music conservatories and university music programs as rehearsal and practice instruments, and they are popular models for in-home purchase. The top of a spinet model barely rises above the keyboard. Unlike all other pianos, the spinet action is located below the keys, operated by vertical wires that are attached to the backs of the keys. Console pianos, which have a compact action (shorter hammers than a large upright has), but because the console's action is above the keys rather than below them as in a spinet, a console almost always plays better than a spinet does. Console pianos are a few inches shorter than studio models. Studio pianos are around tall. This is the shortest cabinet that can accommodate a full-sized action located above the keyboard. Anything taller than a studio piano is called an upright. (Technically, any piano with a vertically oriented soundboard could be called an upright, but that word is often reserved for the full-size models.) Specialized The toy piano, introduced in the 19th century, is a small piano-like instrument, that generally uses round metal rods to produce sound, rather than strings. The US Library of Congress recognizes the toy piano as a unique instrument with the subject designation, Toy Piano Scores: M175 T69. In 1863, Henri Fourneaux invented the player piano, which plays itself from a piano roll. A machine perforates a performance recording into rolls of paper, and the player piano replays the performance using pneumatic devices. Modern equivalents of the player piano include the Bösendorfer CEUS, Yamaha Disklavier and QRS Pianomation, using solenoids and MIDI rather than pneumatics and rolls. A silent piano is an acoustic piano having an option to silence the strings by means of an interposing hammer bar. They are designed for private silent practice, to avoid disturbing others. Edward Ryley invented the transposing piano in 1801. This rare instrument has a lever under the keyboard to move the keyboard relative to the strings, so a pianist can play in a familiar key while the music sounds in a different key. The minipiano is an instrument patented by the Brasted brothers of the Eavestaff Ltd. piano company in 1934. This instrument has a braceless back and a soundboard positioned below the keys—long metal rods pull on the levers to make the hammers strike the strings. The first model, known as the Pianette, was unique in that the tuning pins extended through the instrument, so it could be tuned at the front. The prepared piano, present in some contemporary art music from the 20th and 21st century is a piano which has objects placed inside it to alter its sound, or has had its mechanism changed in some other way. The scores for music for prepared piano specify the modifications, for example, instructing the pianist to insert pieces of rubber, paper, metal screws, or washers in between the strings. These objects mute the strings or alter their timbre. The pedal piano is a rare type of piano that has a pedal keyboard at the base, designed to be played by the feet. The pedals may play the existing bass strings on the piano, or rarely, the pedals may have their own set of bass strings and hammer mechanisms. While the typical intended use for pedal pianos is to enable a keyboardist to practice pipe organ music at home, a few players of pedal piano use it as a performance instrument. Wadia Sabra had a microtone piano manufactured by Pleyel in 1920. Abdallah Chahine later constructed his quartertone "Oriental piano" with the help of Austrian Hofmann. Electric, electronic, and digital With technological advances, amplified electric pianos (1929), electronic pianos (1970s), and digital pianos (1980s) have been developed. The electric piano became a popular instrument in the 1960s and 1970s genres of jazz fusion, funk music and rock music. The first electric pianos from the late 1920s used metal strings with a magnetic pickup, an amplifier and a loudspeaker. The electric pianos that became most popular in pop and rock music in the 1960s and 1970s, such as the Fender Rhodes use metal tines in place of strings and use electromagnetic pickups similar to those on an electric guitar. The resulting electrical, analogue signal can then be amplified with a keyboard amplifier or electronically manipulated with effects units. In classical music, electric pianos are mainly used as inexpensive rehearsal or practice instruments. However, electric pianos, particularly the Fender Rhodes, became important instruments in 1970s funk and jazz fusion and in some rock music genres. Electronic pianos are non-acoustic; they do not have strings, tines or hammers, but are a type of synthesizer that simulates or imitates piano sounds using oscillators and filters that synthesize the sound of an acoustic piano. They must be connected to a keyboard amplifier and speaker to produce sound (however, some electronic keyboards have a built-in amp and speaker). Alternatively, a person can play an electronic piano with headphones in quieter settings. Digital pianos are also non-acoustic and do not have strings or hammers. They use digital sampling technology to reproduce the acoustic sound of each piano note accurately. They also must be connected to a power amplifier and speaker to produce sound (however, most digital pianos have a built-in amp and speaker). Alternatively, a person can practice with headphones to avoid disturbing others. Digital pianos can include sustain pedals, weighted or semi-weighted keys, multiple voice options (e.g., sampled or synthesized imitations of electric piano, Hammond organ, violin, etc.), and MIDI interfaces. MIDI inputs and outputs connect a digital piano to other electronic instruments or musical devices. For example, a digital piano's MIDI out signal could be connected by a patch cord to a synth module, which would allow the performer to use the keyboard of the digital piano to play modern synthesizer sounds. Early digital pianos tended to lack a full set of pedals but the synthesis software of later models such as the Yamaha Clavinova series synthesised the sympathetic vibration of the other strings (such as when the sustain pedal is depressed) and full pedal sets can now be replicated. The processing power of digital pianos has enabled highly realistic pianos using multi-gigabyte piano sample sets with as many as ninety recordings, each lasting many seconds, for each key under different conditions (e.g., there are samples of each note being struck softly, loudly, with a sharp attack, etc.). Additional samples emulate sympathetic resonance of the strings when the sustain pedal is depressed, key release, the drop of the dampers, and simulations of techniques such as re-pedalling. Digital, MIDI-equipped, pianos can output a stream of MIDI data, or record and play via a CD ROM or USB flash drive using MIDI format files, similar in concept to a pianola. The MIDI file records the physics of a note rather than its resulting sound and recreates the sounds from its physical properties (e.g., which note was struck and with what velocity). Computer based software, such as Modartt's 2006 Pianoteq, can be used to manipulate the MIDI stream in real time or subsequently to edit it. This type of software may use no samples but synthesize a sound based on aspects of the physics that went into the creation of a played note. Hybrid instruments In the 2000s, some pianos include an acoustic grand piano or upright piano combined with MIDI electronic features. Such a piano can be played acoustically, or the keyboard can be used as a MIDI controller, which can trigger a synthesizer module or music sampler. Some electronic feature-equipped pianos such as the Yamaha Disklavier electronic player piano, introduced in 1987, are outfitted with electronic sensors for recording and electromechanical solenoids for player piano-style playback. Sensors record the movements of the keys, hammers, and pedals during a performance, and the system saves the performance data as a Standard MIDI File (SMF). On playback, the solenoids move the keys and pedals and thus reproduce the original performance. Modern Disklaviers typically include an array of electronic features, such as a built-in tone generator for playing back MIDI accompaniment tracks, speakers, MIDI connectivity that supports communication with computing devices and external MIDI instruments, additional ports for audio and SMPTE input/output (I/O), and Internet connectivity. Disklaviers have been manufactured in the form of upright, baby grand, and grand piano styles (including a nine-foot concert grand). Reproducing systems have ranged from relatively simple, playback-only models to professional models that can record performance data at resolutions that exceed the limits of normal MIDI data. The unit mounted under the keyboard of the piano can play MIDI or audio software on its CD. Construction and components Pianos can have over 12,000 individual parts, supporting six functional features: keyboard, hammers, dampers, bridge, soundboard, and strings. Many parts of a piano are made of materials selected for strength and longevity. This is especially true of the outer rim. It is most commonly made of hardwood, typically hard maple or beech, and its massiveness serves as an essentially immobile object from which the flexible soundboard can best vibrate. According to Harold A. Conklin, the purpose of a sturdy rim is so that, "... the vibrational energy will stay as much as possible in the soundboard instead of dissipating uselessly in the case parts, which are inefficient radiators of sound." Hardwood rims are commonly made by laminating thin, hence flexible, strips of hardwood, bending them to the desired shape immediately after the application of glue. The bent plywood system was developed by C.F. Theodore Steinway in 1880 to reduce manufacturing time and costs. Previously, the rim was constructed from several pieces of solid wood, joined and veneered, and European makers used this method well into the 20th century. A modern exception, Bösendorfer, the Austrian manufacturer of high-quality pianos, constructs their inner rims from solid spruce, the same wood that the soundboard is made from, which is notched to allow it to bend; rather than isolating the rim from vibration, their "resonance case principle" allows the framework to resonate more freely with the soundboard, creating additional coloration and complexity of the overall sound. The thick wooden posts on the underside (grands) or back (uprights) of the piano stabilize the rim structure, and are made of softwood for stability. The requirement of structural strength, fulfilled by stout hardwood and thick metal, makes a piano heavy. Even a small upright can weigh , and the Steinway concert grand (Model D) weighs . The largest piano available on the general market, the Fazioli F308, weighs . The pinblock, which holds the tuning pins in place, is another area where toughness is important. It is made of hardwood (typically hard maple or beech), and is laminated for strength, stability and longevity. Piano strings (also called piano wire), which must endure years of extreme tension and hard blows, are made of high carbon steel. They are manufactured to vary as little as possible in diameter, since all deviations from uniformity introduce tonal distortion. The bass strings of a piano are made of a steel core wrapped with copper wire, to increase their mass whilst retaining flexibility. If all strings throughout the piano's compass were individual (monochord), the massive bass strings would overpower the upper ranges. Makers compensate for this with the use of double (bichord) strings in the tenor and triple (trichord) strings throughout the treble. The plate (harp), or metal frame, of a piano is usually made of cast iron. A massive plate is advantageous. Since the strings vibrate from the plate at both ends, an insufficiently massive plate would absorb too much of the vibrational energy that should go through the bridge to the soundboard. While some manufacturers use cast steel in their plates, most prefer cast iron. Cast iron is easy to cast and machine, has flexibility sufficient for piano use, is much more resistant to deformation than steel, and is especially tolerant of compression. Plate casting is an art, since dimensions are crucial and the iron shrinks about one percent during cooling. Including an extremely large piece of metal in a piano is potentially an aesthetic handicap. Piano makers overcome this by polishing, painting, and decorating the plate. Plates often include the manufacturer's ornamental medallion. In an effort to make pianos lighter, Alcoa worked with Winter and Company piano manufacturers to make pianos using an aluminum plate during the 1940s. Aluminum piano plates were not widely accepted, and were discontinued. The numerous parts of a piano action are generally made from hardwood, such as maple, beech, and hornbeam; however, since World War II, makers have also incorporated plastics. Early plastics used in some pianos in the late 1940s and 1950s, proved disastrous when they lost strength after a few decades of use. Beginning in 1961, the New York branch of the Steinway firm incorporated Teflon, a synthetic material developed by DuPont, for some parts of its Permafree grand action in place of cloth bushings, but abandoned the experiment in 1982 due to excessive friction and a "clicking" that developed over time; Teflon is "humidity stable" whereas the wood adjacent to the Teflon swells and shrinks with humidity changes, causing problems. More recently, the Kawai firm built pianos with action parts made of more modern materials such as carbon fiber reinforced plastic, and the piano parts manufacturer Wessell, Nickel and Gross has launched a new line of carefully engineered composite parts. Thus far these parts have performed reasonably, but it will take decades to know if they equal the longevity of wood. In all but the lowest quality pianos the soundboard is made of solid spruce (that is, spruce boards glued together along the side grain). Spruce's high ratio of strength to weight minimizes acoustic impedance while offering strength sufficient to withstand the downward force of the strings. The best piano makers use quarter-sawn, defect-free spruce of close annular grain, carefully seasoning it over a long period before fabricating the soundboards. This is the identical material that is used in quality acoustic guitar soundboards. Cheap pianos often have plywood soundboards. The design of the piano hammers requires having the hammer felt be soft enough so that it will not create loud, very high harmonics that a hard hammer will cause. The hammer must be lightweight enough to move swiftly when a key is pressed; yet at the same time, it must be strong enough so that it can hit strings hard when the player strikes the keys forcefully for fortissimo playing or sforzando accents. Keyboard In the early years of piano construction, keys were commonly made from sugar pine. In the 2010s, they are usually made of spruce or basswood. Spruce is typically used in high-quality pianos. Black keys were traditionally made of ebony, and the white keys were covered with strips of ivory. However, since ivory-yielding species are now endangered and protected by treaty, or are illegal in some countries, makers use plastics almost exclusively. Also, ivory tends to chip more easily than plastic. Legal ivory can still be obtained in limited quantities. Yamaha developed a plastic called Ivorite intended to mimic the look and feel of ivory; other manufacturers have done likewise. Almost every modern piano has 52 white keys and 36 black keys for a total of 88 keys (seven octaves plus a minor third, from A0 to C8). Many older pianos only have 85 keys (seven octaves from A0 to A7). Some piano manufacturers have extended the range further in one or both directions. For example, the Imperial Bösendorfer has nine extra keys at the bass end, giving a total of 97 keys and an eight octave range. These extra keys are sometimes hidden under a small hinged lid that can cover the keys to prevent visual disorientation for pianists unfamiliar with the extra keys, or the colours of the extra white keys are reversed (black instead of white). More recently, Australian manufacturer Stuart & Sons created a piano with 108 keys, going from C0 to B8, covering nine full octaves. The extra keys are the same as the other keys in appearance. The extra keys are added primarily for increased resonance from the associated strings; that is, they vibrate sympathetically with other strings whenever the damper pedal is depressed and thus give a fuller tone. Only a very small number of works composed for piano actually use these notes. Toy piano company Schoenhut manufactures grands and uprights with only 44 or 49 keys and a shorter distance between the keyboard and the pedals. These are true pianos with working mechanisms and strings. A rare variant of the piano called the Emánuel Moór Pianoforte has double keyboards, one lying above the other. It was invented by Hungarian composer and pianist, Emánuel Moór (19 February 1863 – 20 October 1931). The lower keyboard has the usual 88 keys, whilst the upper keyboard has 76 keys. When the upper keyboard is played, an internal mechanism pulls down the corresponding key on the lower keyboard, but an octave higher. This lets a pianist reach two octaves with one hand, impossible on a conventional piano. Due to its double keyboard, musical works that were originally created for double-manual harpsichord, such as the Goldberg Variations by Bach, become much easier to play, since playing on a conventional single keyboard piano involves complex and hand-tangling cross-hand movements. The design also features a special fourth pedal that couples the lower and upper keyboard, so when playing on the lower keyboard the note one octave higher also plays. Only about 60 Emánuel Moór Pianofortes were made, mostly by Bösendorfer. Other piano manufacturers, such as Bechstein, Chickering, and Steinway & Sons, also manufactured a few. Pianos have been built with alternative keyboard systems, e.g., the Jankó keyboard. Pedals Pianos have had pedals, or some close equivalent, since the earliest days. (In the 18th century, some pianos used levers pressed upward by the player's knee instead of pedals.) Most grand pianos in the US have three pedals: the soft pedal (una corda), sostenuto, and sustain pedal (from left to right, respectively), while in Europe, the standard is two pedals: the soft pedal and the sustain pedal. Most modern upright pianos also have three pedals: soft pedal, practice pedal and sustain pedal, though older or cheaper models may lack the practice pedal. In Europe the standard for upright pianos is two pedals: the soft and the sustain pedals. The sustain pedal (or, damper pedal) is often simply called "the pedal", since it is the most frequently used. It is placed as the rightmost pedal in the group. It lifts the dampers from all keys, sustaining all played notes. In addition, it alters the overall tone by allowing all strings, including those not directly played, to reverberate. When all of the other strings on the piano can vibrate, this allows sympathetic vibration of strings that are harmonically related to the sounded pitches. For example, if the pianist plays the 440 Hz "A" note, the higher octave "A" notes will also sound sympathetically. The soft pedal or una corda pedal is placed leftmost in the row of pedals. In grand pianos it shifts the entire action/keyboard assembly to the right (a very few instruments have shifted left) so that the hammers hit two of the three strings for each note. In the earliest pianos whose unisons were bichords rather than trichords, the action shifted so that hammers hit a single string, hence the name una corda, or 'one string'. The effect is to soften the note as well as change the tone. In uprights this action is not possible; instead the pedal moves the hammers closer to the strings, allowing the hammers to strike with less kinetic energy. This produces a slightly softer sound, but no change in timbre. On grand pianos, the middle pedal is a sostenuto pedal. This pedal keeps raised any damper already raised at the moment the pedal is depressed. This makes it possible to sustain selected notes (by depressing the sostenuto pedal before those notes are released) while the player's hands are free to play additional notes (which don't sustain). This can be useful for musical passages with low bass pedal points, in which a bass note is sustained while a series of chords changes over top of it, and other otherwise tricky parts. On many upright pianos, the middle pedal is called the "practice" or celeste pedal. This drops a piece of felt between the hammers and strings, greatly muting the sounds. This pedal can be shifted while depressed, into a "locking" position. There are also non-standard variants. On some pianos (grands and verticals), the middle pedal can be a bass sustain pedal: that is, when it is depressed, the dampers lift off the strings only in the bass section. Players use this pedal to sustain a single bass note or chord over many measures, while playing the melody in the treble section. The rare transposing piano (an example of which was owned by Irving Berlin) has a middle pedal that functions as a clutch that disengages the keyboard from the mechanism, so the player can move the keyboard to the left or right with a lever. This shifts the entire piano action so the pianist can play music written in one key so that it sounds in a different key. Some piano companies have included extra pedals other than the standard two or three. On the Stuart and Sons pianos as well as the largest Fazioli piano, there is a fourth pedal to the left of the principal three. This fourth pedal works in the same way as the soft pedal of an upright piano, moving the hammers closer to the strings. The Crown and Schubert Piano Company also produced a four-pedal piano. Wing and Son of New York offered a five-pedal piano from approximately 1893 through the 1920s. There is no mention of the company past the 1930s. Labeled left to right, the pedals are Mandolin, Orchestra, Expression, Soft, and Forte (Sustain). The Orchestral pedal produced a sound similar to a tremolo feel by bouncing a set of small beads dangling against the strings, enabling the piano to mimic a mandolin, guitar, banjo, zither and harp, thus the name Orchestral. The Mandolin pedal used a similar approach, lowering a set of felt strips with metal rings in between the hammers and the strings (aka rinky-tink effect). This extended the life of the hammers when the Orch pedal was used, a good idea for practicing, and created an echo-like sound that mimicked playing in an orchestral hall. The pedalier piano, or pedal piano, is a rare type of piano that includes a pedalboard so players can use their feet to play bass register notes, as on an organ. There are two types of pedal piano. On one, the pedal board is an integral part of the instrument, using the same strings and mechanism as the manual keyboard. The other, rarer type, consists of two independent pianos (each with separate mechanics and strings) placed one above the other—one for the hands and one for the feet. This was developed primarily as a practice instrument for organists, though there is a small repertoire written specifically for the instrument. Mechanics When the key is struck, a chain reaction occurs to produce the sound. First, the key raises the "wippen" mechanism, which forces the jack against the hammer roller (or knuckle). The hammer roller then lifts the lever carrying the hammer. The key also raises the damper; and immediately after the hammer strikes the wire it falls back, allowing the wire to resonate and thus produce sound. When the key is released the damper falls back onto the strings, stopping the wire from vibrating, and thus stopping the sound. The vibrating piano strings themselves are not very loud, but their vibrations are transmitted to a large soundboard that moves air and thus converts the energy to sound. The irregular shape and off-center placement of the bridge ensure that the soundboard vibrates strongly at all frequencies. The raised damper allows the note to sound until the key (or sustain pedal) is released. There are three factors that influence the pitch of a vibrating wire. Length: All other factors the same, the shorter the wire, the higher the pitch. Mass per unit length: All other factors the same, the thinner the wire, the higher the pitch. Tension: All other factors the same, the tighter the wire, the higher the pitch. A vibrating wire subdivides itself into many parts vibrating at the same time. Each part produces a pitch of its own, called a partial. A vibrating string has one fundamental and a series of partials. The purest combination of |

of a GRC. The PAP has used this tactic to its advantage on several occasions. Rather than stand in an uncontested GRC, in 1997, then-Prime Minister Goh Chok Tong shifted his attention to campaigning for candidates where the PAP believed they were most vulnerable, which was the Cheng San GRC. The opposition has charged the government with gerrymandering due to the changing of GRC boundaries at very short notice (see below section on electoral boundaries). Critics have noted that Joshua Benjamin Jeyaratnam won the 1981 Anson by-election in a Chinese-majority constituency, and that since the GRC system was implemented, minority representation in Parliament has actually declined. Boundaries and gerrymandering allegations The boundaries of electoral constituencies in Singapore are decided by the Elections Department, which is under the control of the Prime Minister's Office. Electoral boundaries are generally announced close to elections, usually a few days before the election itself is announced. There have been accusations of gerrymandering regarding the redrawing of electoral boundaries and the dissolving of constituencies that return a high percentage of votes for parties other than the ruling PAP. One of the cases that is often cited as evidence for gerrymandering in Singapore is the case of the Cheng San Group Representation Constituency (GRC). In the | Singapore's Parliament would continue to be multiracial in its composition and representation. Opposition parties have criticized GRCs as making it even more difficult for non-PAP candidates to be elected to Parliament. The money required to contest a GRC is considerable as each candidate is required to pay a deposit ranging from S$4,000 to S$16,000 (the recent election is S$13,500). This means that contesting a GRC is very costly for opposition parties. The presence of Cabinet Ministers in GRCs is often believed to give the PAP a considerable advantage in the contesting of a GRC. The PAP has used this tactic to its advantage on several occasions.

hit singles "You Really Got Me" and "All Day and All of the Night", were both influenced by "Louie, Louie". In 1965, the Who released the mod anthem, "My Generation", which according to John Reed, anticipated the kind of "cerebral mix of musical ferocity and rebellious posture" that would characterize much of the later British punk rock of the 1970s. The garage/beat phenomenon extended beyond North America and Britain. Proto-punk In August 1969, the Stooges, from Ann Arbor, premiered with a self-titled album. According to critic Greil Marcus, the band, led by singer Iggy Pop, created "the sound of Chuck Berry's Airmobile—after thieves stripped it for parts". The album was produced by John Cale, a former member of New York's experimental rock group the Velvet Underground, who inspired many of those involved in the creation of punk rock. The New York Dolls updated 1950s' rock 'n' roll in a fashion that later became known as glam punk. The New York duo Suicide played spare, experimental music with a confrontational stage act inspired by that of the Stooges. In Boston, the Modern Lovers, led by Jonathan Richman, minimalistic style gained attention. In 1974, as well, the Detroit band Death—made up of three African-American brothers—recorded "scorching blasts of feral ur-punk", but could not arrange a release deal. In Ohio, a small but influential underground rock scene emerged, led by Devo in Akron and Kent and by Cleveland's Electric Eels, Mirrors and Rocket from the Tombs. Bands anticipating the forthcoming movement were appearing as far afield as Düsseldorf, West Germany, where "punk before punk" band Neu! formed in 1971, building on the Krautrock tradition of groups such as Can. In Japan, the anti-establishment (Brain Police) mixed garage-psych and folk. The combo regularly faced censorship challenges, their live act at least once including onstage masturbation. A new generation of Australian garage rock bands, inspired mainly by the Stooges and MC5, was coming closer to the sound that would soon be called "punk": In Brisbane, the Saints evoked the live sound of the British Pretty Things, who had toured Australia and New Zealand in 1975. Etymology Between the late 16th and the 18th centuries, punk was a common, coarse synonym for prostitute; William Shakespeare used it with that meaning in The Merry Wives of Windsor (1602) and Measure for Measure (1603-4). The term eventually came to describe "a young male hustler, a gangster, a hoodlum, or a ruffian". The first known use of the phrase "punk rock" appeared in the Chicago Tribune on March 22, 1970, when Ed Sanders, cofounder of New York's anarcho-prankster band the Fugs described his first solo album as "punk rock – redneck sentimentality". In 1969 Sanders recorded a song for album called "Street Punk" but it was only released in 2008. In the December 1970 issue of Creem, Lester Bangs, mocking more mainstream rock musicians, ironically referred to Iggy Pop as "that Stooge punk". Suicide's Alan Vega credits this usage with inspiring his duo to bill its gigs as "punk music" or a "punk mass" for the next couple of years. In the March 1971 issue of Creem, critic Greg Shaw wrote about the Shadows of Knight’s “hard-edge punk sound”. In an April 1971 issue of Rolling Stone, he referred to a track by the Guess Who as "good, not too imaginative, punk rock and roll". The same month John Medelsohn described Alice Cooper's album Love It To Death as "nicely wrought mainstream punk raunch". Dave Marsh used the term in the May 1971 issue of Creem, where he described ? and the Mysterians as giving a "landmark exposition of punk rock". Later in 1971, in his fanzine Who Put the Bomp, Greg Shaw wrote about "what I have chosen to call "punkrock" bands—white teenage hard rock of '64–66 (Standells, Kingsmen, Shadows of Knight, etc.)". Lester Bangs used the term "punk rock" in several articles written in the early 1970s to refer to mid-1960s garage acts. In the liner notes of the 1972 anthology LP, Nuggets, musician and rock journalist Lenny Kaye, later a member of the Patti Smith Group, used the term "punk rock" to describe the genre of 1960s garage bands and "garage-punk", to describe a song recorded in 1966 by the Shadows of Knight. Nick Kent referred to Iggy Pop as the "Punk Messiah of the Teenage Wasteland" in his review of the Stooges July, 1972 performance at King’s Cross Cinema in London for a British magazine called Cream (no relation to the more famous US publication). In the January 1973 Rolling Stone review of Nuggets, Greg Shaw commented "Punk rock is a fascinating genre... Punk rock at its best is the closest we came in the '60s to the original rockabilly spirit of Rock 'n Roll." In February 1973, Terry Atkinson of the Los Angeles Times, reviewing the debut album by a hard rock band, Aerosmith, declared that it "achieves all that punk-rock bands strive for but most miss." A March 1973 review of an Iggy and the Stooges show in the Detroit Free Press dismissively referred to Pop as "the apothesis of Detroit punk music". In May 1973, Billy Altman launched the short-lived punk magazine, which pre-dated the better-known 1975 publication of the same name, but, unlike the later magazine, was largely devoted to discussion of 1960s garage and psychedelic acts. In May 1974, Los Angeles Times critic Robert Hilburn reviewed the second New York Dolls album, Too Much Too Soon. "I told ya the New York Dolls were the real thing," he wrote, describing the album as "perhaps the best example of raw, thumb-your-nose-at-the-world, punk rock since the Rolling Stones' Exile on Main Street." In a 1974 interview for his fanzine Heavy Metal Digest Danny Sugerman told Iggy Pop "You went on record as saying you never were a punk" and Iggy replied "...well I ain't. I never was a punk." By 1975, punk was being used to describe acts as diverse as the Patti Smith Group, the Bay City Rollers, and Bruce Springsteen. As the scene at New York's CBGB club attracted notice, a name was sought for the developing sound. Club owner Hilly Kristal called the movement "Street rock"; John Holmstrom credits Aquarian magazine with using punk "to describe what was going on at CBGBs". Holmstrom, Legs McNeil, and Ged Dunn's magazine Punk, which debuted at the end of 1975, was crucial in codifying the term. "It was pretty obvious that the word was getting very popular", Holmstrom later remarked. "We figured we'd take the name before anyone else claimed it. We wanted to get rid of the bullshit, strip it down to rock 'n' roll. We wanted the fun and liveliness back." 1974–1976: Early history North America New York City The origins of New York's punk rock scene can be traced back to such sources as late 1960s trash culture and an early 1970s underground rock movement centered on the Mercer Arts Center in Greenwich Village, where the New York Dolls performed. In early 1974, a new scene began to develop around the CBGB club, also in lower Manhattan. At its core was Television, described by critic John Walker as "the ultimate garage band with pretensions". Their influences ranged from the Velvet Underground to the staccato guitar work of Dr. Feelgood's Wilko Johnson. The band's bassist/singer, Richard Hell, created a look with cropped, ragged hair, ripped T-shirts, and black leather jackets credited as the basis for punk rock visual style. In April 1974, Patti Smith came to CBGB for the first time to see the band perform. A veteran of independent theater and performance poetry, Smith was developing an intellectual, feminist take on rock 'n' roll. On June 5, she recorded the single "Hey Joe"/"Piss Factory", featuring Television guitarist Tom Verlaine; released on her own Mer Records label, it heralded the scene's DIY ethic and has often been cited as the first punk rock record. By August, Smith and Television were gigging together at Max's Kansas City. In Forest Hills, Queens, the Ramones drew on sources ranging from the Stooges to the Beatles and the Beach Boys to Herman's Hermits and 1960s girl groups, and condensed rock 'n' roll to its primal level: 1-2-3-4!' bass-player Dee Dee Ramone shouted at the start of every song, as if the group could barely master the rudiments of rhythm." The band played its first show at CBGB in August 1974. By the end of the year, the Ramones had performed seventy-four shows, each about seventeen minutes long. "When I first saw the Ramones", critic Mary Harron later remembered, "I couldn't believe people were doing this. The dumb brattiness." That spring, Smith and Television shared a two-month-long weekend residency at CBGB that significantly raised the club's profile. The Television sets included Richard Hell's "Blank Generation", which became the scene's emblematic anthem. Soon after, Hell left Television and founded a band featuring a more stripped-down sound, the Heartbreakers, with former New York Dolls Johnny Thunders and Jerry Nolan. In August, Television recorded a single, "Little Johnny Jewel". In the words of John Walker, the record was "a turning point for the whole New York scene" if not quite for the punk rock sound itself—Hell's departure had left the band "significantly reduced in fringe aggression". Early in 1976, Hell left the Heartbreakers to form the Voidoids, described as "one of the most harshly uncompromising [punk] bands". That April, the Ramones' debut album was released by Sire Records; the first single was "Blitzkrieg Bop", opening with the rally cry "Hey! Ho! Let's go!" According to a later description, "Like all cultural watersheds, Ramones was embraced by a discerning few and slagged off as a bad joke by the uncomprehending majority." Other New York venues apart from CBGB included the Lismar Lounge (41 First Avenue) and Aztec Lounge (9th Street). At this early stage, the term punk applied to the scene in general, not necessarily a particular stylistic approach as it would later—the early New York punk bands represented a broad variety of influences. Among them, the Ramones, the Heartbreakers, Richard Hell and the Voidoids, and the Dead Boys were establishing a distinct musical style. Even where they diverged most clearly, in lyrical approach—the Ramones' apparent guilelessness at one extreme, Hell's conscious craft at the other—there was an abrasive attitude in common. Their shared attributes of minimalism and speed, however, had not yet come to define punk rock. United Kingdom After a brief period unofficially managing the New York Dolls, Briton Malcolm McLaren returned to London in May 1975, inspired by the new scene he had witnessed at CBGB. The King's Road clothing store he co-owned, recently renamed Sex, was building a reputation with its outrageous "anti-fashion". Among those who frequented the shop were members of a band called the Strand, which McLaren had also been managing. In August, the group was seeking a new lead singer. Another Sex habitué, Johnny Rotten, auditioned for and won the job. Adopting a new name, the group played its first gig as the Sex Pistols on 6 November 1975, at Saint Martin's School of Art, and soon attracted a small but dedicated following. In February 1976, the band received its first significant press coverage; guitarist Steve Jones declared that the Sex Pistols were not so much into music as they were "chaos". The band often provoked its crowds into near-riots. Rotten announced to one audience, "Bet you don't hate us as much as we hate you!" McLaren envisioned the Sex Pistols as central players in a new youth movement, "hard and tough". As described by critic Jon Savage, the band members "embodied an attitude into which McLaren fed a new set of references: late-sixties radical politics, sexual fetish material, pop history, ... youth sociology". Bernard Rhodes, an associate of McLaren, similarly aimed to make stars of the band London SS, who became the Clash, which was joined by Joe Strummer. On 4 June 1976, the Sex Pistols played Manchester's Lesser Free Trade Hall in what became one of the most influential rock shows ever. Among the approximately forty audience members were the two locals who organised the gig—they had formed Buzzcocks after seeing the Sex Pistols in February. Others in the small crowd went on to form Joy Division, the Fall, and—in the 1980s—the Smiths. In July, the Ramones played two London shows that helped spark the nascent UK punk scene. Over the next several months, many new punk rock bands formed, often directly inspired by the Sex Pistols. In London, women were near the center of the scene—among the initial wave of bands were the female-fronted Siouxsie and the Banshees and X-Ray Spex and the all-female the Slits. There were female bassists Gaye Advert in the Adverts and Shanne Bradley in the Nipple Erectors, while Sex store frontwoman Jordan not only managed Adam and the Ants but also performed screaming vocals on their song "Lou". Other groups included Subway Sect, Alternative TV, Wire, the Stranglers, Eater and Generation X. Farther afield, Sham 69 began practicing in the southeastern town of Hersham. In Durham, there was Penetration, with lead singer Pauline Murray. On September 20–21, the 100 Club Punk Festival in London featured the Sex Pistols, Clash, Damned and Buzzcocks, as well as Paris's female-lead Stinky Toys. Siouxsie and the Banshees and Subway Sect debuted on the festival's first night. On the festival's second night, audience member Sid Vicious was arrested having thrown a glass at the Damned that shattered and destroyed a girl's eye. Press coverage of the incident reinforced punk's reputation as a social menace. Some new bands, such as London's Ultravox!, Edinburgh's Rezillos, Manchester's the Fall, and Leamington's the Shapes, identified with the scene even as they pursued more experimental music. Others of a comparatively traditional rock 'n' roll bent were also swept up by the movement: the Vibrators, formed as a pub rock–style act in February 1976, soon adopted a punk look and sound. A few even longer-active bands including Surrey neo-mods the Jam and pub rockers Eddie and the Hot Rods, the Stranglers and Cock Sparrer also became associated with the punk rock scene. Alongside the musical roots shared with their American counterparts and the calculated confrontationalism of the early Who, the British punks also reflected the influence of glam rock and related artists and bands such as David Bowie, Slade, T.Rex, and Roxy Music. In October 1976, the Damned released the first UK punk rock band single, "New Rose". The Vibrators followed the next month with "We Vibrate". On 26 November 1976, the Sex Pistols' released their debut single "Anarchy in the U.K.", which succeeded in its goal of becoming a "national scandal". Jamie Reid's "anarchy flag" poster and his other design work for the Sex Pistols helped establish a distinctive punk visual aesthetic. On 1 December 1976, an incident took place that sealed punk rock's notorious reputation, when the Sex Pistols and several members of the Bromley Contingent, including Siouxsie Sioux and Steve Severin, filled a vacancy for Queen on the early evening Thames Television London television show Today to be interviewed by host Bill Grundy. When Sex Pistols guitarist Steve Jones was goaded by Grundy to "say something outrageous", Jones proceeded to call Grundy a "dirty bastard", a "dirty fucker" and a "fucking rotter" on live television, triggering a media controversy. Two days later, the Sex Pistols, the Clash, the Damned, and the Heartbreakers set out on the Anarchy Tour, a series of gigs throughout the UK. Many of the shows were cancelled by venue owners in response to the media outrage following the Grundy interview. Australia A punk subculture began in Australia around the same time, centered around Radio Birdman and the Oxford Tavern in Sydney's Darlinghurst suburb. By 1976, the Saints were hiring Brisbane local halls to use as venues, or playing in "Club 76", their shared house in the inner suburb of Petrie Terrace. The band soon discovered that musicians were exploring similar paths in other parts of the world. Ed Kuepper, co-founder of the Saints, later recalled: One thing I remember having had a really depressing effect on me was the first Ramones album. When I heard it [in 1976], I mean it was a great record ... but I hated it because I knew we'd been doing this sort of stuff for years. There was even a chord progression on that album that we used ... and I thought, "Fuck. We're going to be labeled as influenced by the Ramones", when nothing could have been further from the truth. In Perth, the Cheap Nasties formed in August. In September 1976, the Saints became the first punk rock band outside the U.S. to release a recording, the single "(I'm) Stranded". The band self-financed, packaged, and distributed the single. "(I'm) Stranded" had limited impact at home, but the British music press recognized it as groundbreaking. 1977–1978: Second wave A second wave of punk rock emerged in 1977. These bands often sounded very different from each other. While punk remained largely an underground phenomenon in the US, in the UK it had become a major sensation. North America The California punk scene was fully developed by early 1977. In Los Angeles, there were: the Weirdos, the Zeros, the Bags, Black Randy and the Metrosquad, the Germs, Fear, The Go-Go's, X, the Dickies, and the relocated Tupperwares, now dubbed the Screamers. Black Flag, then-Panic, formed in Hermosa Beach in 1976. They developed a hardcore punk sound and played their debut public performance in a garage in Redondo Beach in December 1977. San Francisco's second wave included the Avengers, The Nuns, Negative Trend, the Mutants, and the Sleepers. By mid-1977 in downtown New York, bands such as Teenage Jesus and the Jerks led what became known as no wave. The Cramps, whose core members were from Sacramento, California by way of Akron, had debuted at CBGB in November 1976, opening for the Dead Boys. They were soon playing regularly at Max's Kansas City. The Misfits formed in nearby New Jersey. Still developing what would become their signature B movie–inspired style, later dubbed horror punk, they made their first appearance at CBGB in April 1977. The Dead Boys' debut LP, Young, Loud and Snotty, was released at the end of August. October saw two more debut albums from the scene: Richard Hell and the Voidoids' first full-length, Blank Generation, and the Heartbreakers' L.A.M.F.{ One track on the latter exemplified both the scene's close-knit character and the popularity of heroin within it: "Chinese Rocks"—the title refers to a strong form of the drug—was written by Dee Dee Ramone and Hell, both users, as were the Heartbreakers' Thunders and Nolan. (During the Heartbreakers' 1976 and 1977 tours of Britain, Thunders played a central role in popularizing heroin among the punk crowd there, as well.) The Ramones' third album, Rocket to Russia, appeared in November 1977. United Kingdom The Sex Pistols' live TV skirmish with Bill Grundy on December 1, 1976, was the signal moment in British punk's transformation into a major media phenomenon, even as some stores refused to stock the records and radio airplay was hard to come by. Press coverage of punk misbehavior grew intense: On January 4, 1977, The Evening News of London ran a front-page story on how the Sex Pistols "vomited and spat their way to an Amsterdam flight". In February 1977, the first album by a British punk band appeared: Damned Damned Damned (by the Damned) reached number thirty-six on the UK chart. The EP Spiral Scratch, self-released by Manchester's Buzzcocks, was a benchmark for both the DIY ethic and regionalism in the country's punk movement. The Clash's self-titled debut album came out two months later and rose to number twelve; the single "White Riot" entered the top forty. In May, the Sex Pistols achieved new heights of controversy (and number two on the singles chart) with "God Save the Queen". The band had recently acquired a new bassist, Sid Vicious, who was seen as exemplifying the punk persona. The swearing during the Grundy interview and the controversy over "God Save the Queen" led to a moral panic. Scores of new punk groups formed around the United Kingdom, as far from London as Belfast's Stiff Little Fingers and Dunfermline, Scotland's the Skids. Though most survived only briefly, perhaps recording a small-label single or two, others set off new trends. Crass, from Essex, merged a vehement, straight-ahead punk rock style with a committed anarchist mission, and played a major role in the emerging anarcho-punk movement. Sham 69, London's Menace, and the Angelic Upstarts from South Shields in the Northeast combined a similarly stripped-down sound with populist lyrics, a style that became known as street punk. These expressly working-class bands contrasted with others in the second wave that presaged the post-punk phenomenon. Liverpool's first punk group, Big in Japan, moved in a glam, theatrical direction. The band did not survive long, but it spun off several well-known post-punk acts. The songs of London's Wire were characterized by sophisticated lyrics, minimalist arrangements, and extreme brevity. Alongside thirteen original songs that would define classic punk rock, the Clash's debut had included a cover of the recent Jamaican reggae hit "Police and Thieves". Other first wave bands such as the Slits and new entrants to the scene like the Ruts and the Police interacted with the reggae and ska subcultures, incorporating their rhythms and production styles. The punk rock phenomenon helped spark a full-fledged ska revival movement known as 2 Tone, centered on bands such as the Specials, the Beat, Madness and the Selecter. In July, the Sex Pistols' third single, "Pretty Vacant", reached number six and Australia's the Saints had a top-forty hit with "This Perfect Day". In September, Generation X and the Clash reached the top forty with, respectively, "Your Generation" and "Complete Control". X-Ray Spex's "Oh Bondage Up Yours!" did not chart, but it became a requisite item for punk fans. The BBC banned "Oh Bondage Up Yours!" due to its controversial lyrics. In October, the Sex Pistols hit number eight with "Holidays in the Sun", followed by the release of their first and only "official" album, Never Mind the Bollocks, Here's the Sex Pistols. Inspiring yet another round of controversy, it topped the British charts. In December, one of the first books about punk rock was published: The Boy Looked at Johnny, by Julie Burchill and Tony Parsons. Australia In February 1977, EMI released the Saints' debut album, (I'm) Stranded, which the band recorded in two days. The Saints had relocated to Sydney; in April, they and Radio Birdman united for a major gig at Paddington Town Hall. Last Words had also formed in the city. The following month, the Saints relocated again, to Great Britain. In June, Radio Birdman released the album Radios Appear on its own Trafalgar label. 1979–1984: Schism and diversification By 1979, the hardcore punk movement was emerging in Southern California. A rivalry developed between adherents of the new sound and the older punk rock crowd. Hardcore, appealing to a younger, more suburban audience, was perceived by some as anti-intellectual, overly violent, and musically limited. In Los Angeles, the opposing factions were often described as "Hollywood punks" and "beach punks", referring to Hollywood's central position in the original L.A. punk rock scene and to hardcore's popularity in the shoreline communities of South Bay and Orange County. In contrast to North America, more of the bands from the original British punk movement remained active, sustaining extended careers even as their styles evolved and diverged. Meanwhile, the Oi! and anarcho-punk movements were emerging. Musically in the same aggressive vein as American hardcore, they addressed different constituencies with overlapping but distinct anti-establishment messages. As described by Dave Laing, "The model for self-proclaimed punk after 1978 derived from the Ramones via the eight-to-the-bar rhythms most characteristic of the Vibrators and Clash. ... It became essential to sound one particular way to be recognized as a 'punk band' now." In February 1979, former Sex Pistols bassist Sid Vicious died of a heroin overdose in New York. If the Sex Pistols' breakup the previous year had marked the end of the original UK punk scene and its promise of cultural transformation, for many the death of Vicious signified that it had been doomed from the start. By the turn of the decade, the punk rock movement had split deeply along cultural and musical lines, leaving a variety of derivative scenes and forms. On one side were new wave and post-punk artists; some adopted more accessible musical styles and gained broad popularity, while some turned in more experimental, less commercial directions. On the other side, hardcore punk, Oi!, and anarcho-punk bands became closely linked with underground cultures and spun off an array of subgenres. Somewhere in between, pop-punk groups created blends like that of the ideal record, as defined by Mekons cofounder Kevin Lycett: "a cross between Abba and the Sex Pistols". A range of other styles emerged, many of them fusions with long-established genres. The Clash album London Calling, released in December 1979, exemplified the breadth of classic punk's legacy. Combining punk rock with reggae, ska, R&B, and rockabilly, it went on to be acclaimed as one of the best | as "one of the most harshly uncompromising [punk] bands". That April, the Ramones' debut album was released by Sire Records; the first single was "Blitzkrieg Bop", opening with the rally cry "Hey! Ho! Let's go!" According to a later description, "Like all cultural watersheds, Ramones was embraced by a discerning few and slagged off as a bad joke by the uncomprehending majority."

October saw two more debut albums from the scene: Richard Hell and the Voidoids' first full-length, Blank Generation, and the Heartbreakers' L.A.M.F.{ One track on the latter exemplified both the scene's close-knit character and the popularity of heroin within it: "Chinese Rocks"—the title refers to a strong form of the drug—was written by Dee Dee Ramone and Hell, both users, as were the Heartbreakers' Thunders and Nolan. (During the Heartbreakers' 1976 and 1977 tours of Britain, Thunders played a central role in popularizing heroin among the punk crowd there, as well.) The Ramones' third album, Rocket to Russia, appeared in November 1977. United Kingdom The Sex Pistols' live TV skirmish with Bill Grundy on December 1, 1976, was the signal moment in British punk's transformation into a major media phenomenon, even as some stores refused to stock the records and radio airplay was hard to come by. Press coverage of punk misbehavior grew intense: On January 4, 1977, The Evening News of London ran a front-page story on how the Sex Pistols "vomited and spat their way to an Amsterdam flight". In February 1977, the first album by a British punk band appeared: Damned Damned Damned (by the Damned) reached number thirty-six on the UK chart. The EP Spiral Scratch, self-released by Manchester's Buzzcocks, was a benchmark for both the DIY ethic and regionalism in the country's punk movement. The Clash's self-titled debut album came out two months later and rose to number twelve; the single "White Riot" entered the top forty. In May, the Sex Pistols achieved new heights of controversy (and number two on the singles chart) with "God Save the Queen". The band had recently acquired a new bassist, Sid Vicious, who was seen as exemplifying the punk persona. The swearing during the Grundy interview and the controversy over "God Save the Queen" led to a moral panic. Scores of new punk groups formed around the United Kingdom, as far from London as Belfast's Stiff Little Fingers and Dunfermline, Scotland's the Skids. Though most survived only briefly, perhaps recording a small-label single or two, others set off new trends. Crass, from Essex, merged a vehement, straight-ahead punk rock style with a committed anarchist mission, and played a major role in the emerging anarcho-punk movement. Sham 69, London's Menace, and the Angelic Upstarts from South Shields in the Northeast combined a similarly stripped-down sound with populist lyrics, a style that became known as street punk. These expressly working-class bands contrasted with others in the second wave that presaged the post-punk phenomenon. Liverpool's first punk group, Big in Japan, moved in a glam, theatrical direction. The band did not survive long, but it spun off several well-known post-punk acts. The songs of London's Wire were characterized by sophisticated lyrics, minimalist arrangements, and extreme brevity. Alongside thirteen original songs that would define classic punk rock, the Clash's debut had included a cover of the recent Jamaican reggae hit "Police and Thieves". Other first wave bands such as the Slits and new entrants to the scene like the Ruts and the Police interacted with the reggae and ska subcultures, incorporating their rhythms and production styles. The punk rock phenomenon helped spark a full-fledged ska revival movement known as 2 Tone, centered on bands such as the Specials, the Beat, Madness and the Selecter. In July, the Sex Pistols' third single, "Pretty Vacant", reached number six and Australia's the Saints had a top-forty hit with "This Perfect Day". In September, Generation X and the Clash reached the top forty with, respectively, "Your Generation" and "Complete Control". X-Ray Spex's "Oh Bondage Up Yours!" did not chart, but it became a requisite item for punk fans. The BBC banned "Oh Bondage Up Yours!" due to its controversial lyrics. In October, the Sex Pistols hit number eight with "Holidays in the Sun", followed by the release of their first and only "official" album, Never Mind the Bollocks, Here's the Sex Pistols. Inspiring yet another round of controversy, it topped the British charts. In December, one of the first books about punk rock was published: The Boy Looked at Johnny, by Julie Burchill and Tony Parsons. Australia In February 1977, EMI released the Saints' debut album, (I'm) Stranded, which the band recorded in two days. The Saints had relocated to Sydney; in April, they and Radio Birdman united for a major gig at Paddington Town Hall. Last Words had also formed in the city. The following month, the Saints relocated again, to Great Britain. In June, Radio Birdman released the album Radios Appear on its own Trafalgar label. 1979–1984: Schism and diversification By 1979, the hardcore punk movement was emerging in Southern California. A rivalry developed between adherents of the new sound and the older punk rock crowd. Hardcore, appealing to a younger, more suburban audience, was perceived by some as anti-intellectual, overly violent, and musically limited. In Los Angeles, the opposing factions were often described as "Hollywood punks" and "beach punks", referring to Hollywood's central position in the original L.A. punk rock scene and to hardcore's popularity in the shoreline communities of South Bay and Orange County. In contrast to North America, more of the bands from the original British punk movement remained active, sustaining extended careers even as their styles evolved and diverged. Meanwhile, the Oi! and anarcho-punk movements were emerging. Musically in the same aggressive vein as American hardcore, they addressed different constituencies with overlapping but distinct anti-establishment messages. As described by Dave Laing, "The model for self-proclaimed punk after 1978 derived from the Ramones via the eight-to-the-bar rhythms most characteristic of the Vibrators and Clash. ... It became essential to sound one particular way to be recognized as a 'punk band' now." In February 1979, former Sex Pistols bassist Sid Vicious died of a heroin overdose in New York. If the Sex Pistols' breakup the previous year had marked the end of the original UK punk scene and its promise of cultural transformation, for many the death of Vicious signified that it had been doomed from the start. By the turn of the decade, the punk rock movement had split deeply along cultural and musical lines, leaving a variety of derivative scenes and forms. On one side were new wave and post-punk artists; some adopted more accessible musical styles and gained broad popularity, while some turned in more experimental, less commercial directions. On the other side, hardcore punk, Oi!, and anarcho-punk bands became closely linked with underground cultures and spun off an array of subgenres. Somewhere in between, pop-punk groups created blends like that of the ideal record, as defined by Mekons cofounder Kevin Lycett: "a cross between Abba and the Sex Pistols". A range of other styles emerged, many of them fusions with long-established genres. The Clash album London Calling, released in December 1979, exemplified the breadth of classic punk's legacy. Combining punk rock with reggae, ska, R&B, and rockabilly, it went on to be acclaimed as one of the best rock records ever. At the same time, as observed by Flipper singer Bruce Loose, the relatively restrictive hardcore scenes diminished the variety of music that could once be heard at many punk gigs. If early punk, like most rock scenes, was ultimately male-oriented, the hardcore and Oi! scenes were significantly more so, marked in part by the slam dancing and moshing with which they became identified. New wave In 1976—first in London, then in the United States—"New Wave" was introduced as a complementary label for the formative scenes and groups also known as "punk"; the two terms were essentially interchangeable. NME journalist Roy Carr is credited with proposing the term's use (adopted from the cinematic French New Wave of the 1960s) in this context. Over time, "new wave" acquired a distinct meaning: bands such as Blondie and Talking Heads from the CBGB scene; the Cars, who emerged from the Rat in Boston; the Go-Go's in Los Angeles; and the Police in London that were broadening their instrumental palette, incorporating dance-oriented rhythms, and working with more polished production were specifically designated "new wave" and no longer called "punk". Dave Laing suggests that some punk-identified British acts pursued the new wave label in order to avoid radio censorship and make themselves more palatable to concert bookers. Bringing elements of punk rock music and fashion into more pop-oriented, less "dangerous" styles, new wave artists became very popular on both sides of the Atlantic. New wave became a catch-all term, encompassing disparate styles such as 2 Tone ska, the mod revival inspired by the Jam, the sophisticated pop-rock of Elvis Costello and XTC, the New Romantic phenomenon typified by Ultravox, synthpop groups like Tubeway Army (which had started out as a straight-ahead punk band) and Human League, and the sui generis subversions of Devo, who had gone "beyond punk before punk even properly existed". New wave crossed into the mainstream with the debut of the cable television network MTV in 1981, which put many new wave videos into regular rotation. Post-punk During 1976–77, in the midst of the original UK punk movement, bands emerged such as Manchester's Joy Division, the Fall, and Magazine, Leeds' Gang of Four, and London's the Raincoats that became central post-punk figures. Some bands classified as post-punk, such as Throbbing Gristle and Cabaret Voltaire, had been active well before the punk scene coalesced; others, such as Siouxsie and the Banshees and the Slits, transitioned from punk rock into post-punk. A few months after the Sex Pistols' breakup, John Lydon (no longer "Rotten") cofounded Public Image Ltd. Lora Logic, formerly of X-Ray Spex, founded Essential Logic. Killing Joke formed in 1979. These bands were often musically experimental; the term "post-punk" is used to describe sounds that were more dark and abrasive—sometimes verging on the atonal, as with Subway Sect and Wire. The bands incorporated a range of influences ranging from Syd Barrett, Captain Beefheart, David Bowie to Roxy Music to Krautrock. Post-punk brought together a new fraternity of musicians, journalists, managers, and entrepreneurs; the latter, notably Geoff Travis of Rough Trade and Tony Wilson of Factory, helped to develop the production and distribution infrastructure of the indie music scene that blossomed in the mid-1980s. Smoothing the edges of their style in the direction of new wave, several post-punk bands such as New Order and The Cure crossed over to a mainstream U.S. audience. Others, like Gang of Four, the Raincoats and Throbbing Gristle, who had little more than cult followings at the time, are seen in retrospect as significant influences on modern popular culture. Television's debut album Marquee Moon, released in 1977, is frequently cited as a seminal album in the field. The no wave movement that developed in New York in the late 1970s, with artists such as Lydia Lunch and James Chance, is often treated as the phenomenon's U.S. parallel. The later work of Ohio protopunk pioneers Pere Ubu is also commonly described as post-punk. One of the most influential American post-punk bands was Boston's Mission of Burma, who brought abrupt rhythmic shifts derived from hardcore into a highly experimental musical context. In 1980, Australia's Boys Next Door moved to London and changed their name to the Birthday Party, which evolved into Nick Cave and the Bad Seeds. Led by the Primitive Calculators, Melbourne's Little Band scene further explored the possibilities of post-punk. The original post-punk bands were highly influential on 1990s and 2000s alternative rock musicians. Hardcore A distinctive style of punk, characterized by superfast, aggressive beats, screaming vocals, and often politically aware lyrics, began to emerge in 1978 among bands scattered around the United States and Canada. The first major scene of what came to be known as hardcore punk developed in Southern California in 1978–79, initially around such punk bands as the Germs and Fear. The movement soon spread around North America and internationally. According to author Steven Blush, "Hardcore comes from the bleak suburbs of America. Parents moved their kids out of the cities to these horrible suburbs to save them from the 'reality' of the cities and what they ended up with was this new breed of monster". Among the earliest hardcore bands, regarded as having made the first recordings in the style, were Southern California's Middle Class and Black Flag. Bad Brains — all of whom were black, a rarity in punk of any era — launched the D.C. scene with their rapid-paced single "Pay to Cum" in 1980. Austin, Texas's Big Boys, San Francisco's Dead Kennedys, and Vancouver's D.O.A. and were among the other initial hardcore groups. They were soon joined by bands such as the Minutemen, Descendents, and Circle Jerks in Southern California; D.C.'s Minor Threat and State of Alert; and Austin's MDC. By 1981, hardcore was the dominant punk rock style not only in California, but much of the rest of North America as well. A New York hardcore scene grew, including the relocated Bad Brains, New Jersey's Misfits and Adrenalin O.D., and local acts such as the Mob, Reagan Youth, and Agnostic Front. Beastie Boys, who would become famous as a hip-hop group, debuted that year as a hardcore band. They were followed by the Cro-Mags, Murphy's Law, and Leeway. By 1983, St. Paul's Hüsker Dü, Willful Neglect, Chicago's Naked Raygun, Indianapolis's Zero Boys, and D.C.'s the Faith were taking the hardcore sound in experimental and ultimately more melodic directions. Hardcore would constitute the American punk rock standard throughout the decade. The lyrical content of hardcore songs is often critical of commercial culture and middle-class values, as in Dead Kennedys' celebrated "Holiday in Cambodia" (1980). Straight edge bands like Minor Threat, Boston's SS Decontrol, and Reno, Nevada's 7 Seconds rejected the self-destructive lifestyles of their peers, and built a movement based on positivity and abstinence from cigarettes, alcohol, drugs, and casual sex. Skate punk innovators pointed in other directions: including Venice, California's Suicidal Tendencies who had a formative effect on the heavy metal–influenced crossover thrash style. Toward the middle of the decade, D.R.I spawned the superfast thrashcore genre. Oi! Following the lead of first-wave British punk bands Cock Sparrer and Sham 69, in the late 1970s second-wave groups like Cockney Rejects, Angelic Upstarts, the Exploited, and the 4-Skins sought to realign punk rock with a working class, street-level following. They believed the music needed to stay "accessible and unpretentious", in the words of music historian Simon Reynolds. Their style was originally called "real punk" or street punk; Sounds journalist Garry Bushell is credited with labelling the genre Oi! in 1980. The name is partly derived from the Cockney Rejects' habit of shouting "Oi! Oi! Oi!" before each song, instead of the time-honored "1,2,3,4!" The Oi! movement was fueled by a sense that many participants in the early punk rock scene were, in the words of the Business guitarist Steve Kent, "trendy university people using long words, trying to be artistic ... and losing touch". According to Bushell, "Punk was meant to be of the voice of the dole queue, and in reality most of them were not. But Oi was the reality of the punk mythology. In the places where [these bands] came from, it was harder and more aggressive and it produced just as much quality music." Lester Bangs described Oi! as "politicized football chants for unemployed louts". One song in particular, the Exploited's "Punks Not Dead", spoke to an international constituency. It was adopted as an anthem by the groups of disaffected Mexican urban youth known in the 1980s as bandas; one banda named itself PND, after the song's initials. Although most Oi! bands in the initial wave were apolitical or left wing, many of them began to attract a white power skinhead following. Racist skinheads sometimes disrupted Oi! concerts by shouting fascist slogans and starting fights, but some Oi! bands were reluctant to endorse criticism of their fans from what they perceived as the "middle-class establishment". In the popular imagination, the movement thus became linked to the far right. Strength Thru Oi!, an album compiled by Bushell and released in May 1981, stirred controversy, especially when it was revealed that the belligerent figure on the cover was a neo-Nazi jailed for racist violence (Bushell claimed ignorance). On July 3, a concert at Hamborough Tavern in Southall featuring the Business, the 4-Skins, and the Last Resort was firebombed by local Asian youths who believed that the event was a neo-Nazi gathering. Following the Southall riot, press coverage increasingly associated Oi! with the extreme right, and the movement soon began to lose momentum. Anarcho-punk Anarcho-punk developed alongside the Oi! and American hardcore movements. Inspired by Crass, its Dial House commune, and its independent Crass Records label, a scene developed around British bands such as Subhumans, Flux of Pink Indians, Conflict, Poison Girls, and the Apostles that was as concerned with anarchist and DIY principles as it was with music. The acts featured ranting vocals, discordant instrumental sounds, primitive production values, and lyrics filled with political and social content, often addressing issues such as class inequalities and military violence. Anarcho-punk disdained the older punk scene from which theirs had evolved. In historian Tim Gosling's description, they saw "safety pins and Mohicans as little more than ineffectual fashion posturing stimulated by the mainstream media and industry. ... Whereas the Sex Pistols would proudly display bad manners and opportunism in their dealings with 'the establishment,' the anarcho-punks kept clear of 'the establishment' altogether". The movement spun off several subgenres of a similar political bent. Discharge, founded back in 1977, established D-beat in the early 1980s. Other groups in the movement, led by Amebix and Antisect, developed the extreme style known as crust punk. Several of these bands rooted in anarcho-punk such as the Varukers, |
Voegelin and Judith Shklar—encouraged continued study in political philosophy in the Anglo-American world, but in the 1950s and 1960s, they and their students remained at odds with the analytic establishment. Communism remained an important focus especially during the 1950s and 1960s. Colonialism and racism were important issues that arose. In general, there was a marked trend towards a pragmatic approach to political issues, rather than a philosophical one. Much academic debate regarded one or both of two pragmatic topics: how (or whether) to apply utilitarianism to problems of political policy, or how (or whether) to apply economic models (such as rational choice theory) to political issues. The rise of feminism, LGBT social movements and the end of colonial rule and of the political exclusion of such minorities as African Americans and sexual minorities in the developed world has led to feminist, postcolonial, and multicultural thought becoming significant. This led to a challenge to the social contract by philosophers Charles W. Mills in his book The Racial Contract and Carole Pateman in her book The Sexual Contract that the social contract excluded persons of colour and women respectively. In Anglo-American academic political philosophy, the publication of John Rawls's A Theory of Justice in 1971 is considered a milestone. Rawls used a thought experiment, the original position, in which representative parties choose principles of justice for the basic structure of society from behind a veil of ignorance. Rawls also offered a criticism of utilitarian approaches to questions of political justice. Robert Nozick's 1974 book Anarchy, State, and Utopia, which won a National Book Award, responded to Rawls from a libertarian perspective and gained academic respectability for libertarian viewpoints. Contemporaneously with the rise of analytic ethics in Anglo-American thought, in Europe, several new lines of philosophy directed at the critique of existing societies arose between the 1950s and 1980s. Most of these took elements of Marxist economic analysis but combined them with a more cultural or ideological emphasis. Out of the Frankfurt School, thinkers like Herbert Marcuse, Theodor W. Adorno, Max Horkheimer, and Jürgen Habermas combined Marxian and Freudian perspectives. Along somewhat different lines, a number of other continental thinkers—still largely influenced by Marxism—put new emphases on structuralism and on a "return to Hegel". Within the (post-) structuralist line (though mostly not taking that label) are thinkers such as Gilles Deleuze, Michel Foucault, Claude Lefort, and Jean Baudrillard. The Situationists were more influenced by Hegel; Guy Debord, in particular, moved a Marxist analysis of commodity fetishism to the realm of consumption, and looked at the relation between consumerism and dominant ideology formation. Another debate developed around the (distinct) criticisms of liberal political theory made by Michael Walzer, Michael Sandel and Charles Taylor. The liberal-communitarian debate is often considered valuable for generating a new set of philosophical problems, rather than a profound and illuminating clash of perspective. These and other communitarians (such as Alasdair MacIntyre and Daniel A. Bell) argue that, contra liberalism, communities are prior to individuals and therefore should be the center of political focus. Communitarians tend to support greater local control as well as economic and social policies which encourage the growth of social capital. A prominent subject in recent political philosophy is the theory of deliberative democracy. The seminal work was done by Jurgen Habermas in Germany, but the most extensive literature has been in English, led by theorists such as Jane Mansbridge, Joshua Cohen, Amy Gutmann and Dennis Thompson. A pair of overlapping political perspectives arising toward the end of the 20th century are republicanism (or neo- or civic-republicanism) and the capability approach. The resurgent republican movement aims to provide an alternate definition of liberty from Isaiah Berlin's positive and negative forms of liberty, namely "liberty as non-domination." Unlike the American liberal movement which understands liberty as "non-interference," "non-domination" entails individuals not being subject to the arbitrary will of any other person. To a republican the mere status as a slave, regardless of how that slave is treated, is objectionable. Prominent republicans include historian Quentin Skinner, jurist Cass Sunstein, and political philosopher Philip Pettit. The capability approach, pioneered by economists Mahbub ul Haq and Amartya Sen and further developed by legal scholar Martha Nussbaum, understands freedom under allied lines: the real-world ability to act. Both the capability approach and republicanism treat choice as something which must be resourced. In other words, it is not enough to be legally able to do something, but to have the real option of doing it. Another important strand of contemporary political theory in North America draws on thinkers such as Friedrich Nietzsche, Michel Foucault, Jacques Derrida, and Gilles Deleuze, among others, to develop critiques and articulate alternatives to the sufficiency of the liberal-communitarian debate and republicanism discourse. Since the 1990s, these political theorists, broadly engaging the "genealogical approach", "deconstruction", and "weak ontology", have expanded the scope of political theory and issued a variety of arguments on topics such as pluralism, agonism, gender performativity, secularism, and more recently the Anthropocene and the non-human turn. The works of Judith Butler, William E. Connolly, Wendy Brown, Jane Bennett, Bonnie Honig and Chantal Mouffe have been highly pertinent in this regard. Influential political philosophers A larger list of political philosophers is intended to be closer to exhaustive. Listed below are some of the most canonical or important thinkers, and especially philosophers whose central focus was in political philosophy and/or who are good representatives of a particular school of thought. Thomas Aquinas: In synthesizing Christian theology and Peripatetic (Aristotelian) teaching in his Treatise on Law, Aquinas contends that God's gift of higher reason—manifest in human law by way of the divine virtues—gives way to the assembly of righteous government. Aristotle: Wrote his Politics as an extension of his Nicomachean Ethics. Notable for the theories that humans are social animals, and that the polis (Ancient Greek city state) existed to bring about the good life appropriate to such animals. His political theory is based upon an ethics of perfectionism (as is Marx's, on some readings). Mikhail Bakunin: After Pierre Joseph Proudhon, Bakunin became the most important political philosopher of anarchism. His specific version of anarchism is called collectivist anarchism. Jeremy Bentham: The first thinker to analyze social justice in terms of maximization of aggregate individual benefits. Founded the philosophical/ethical school of thought known as utilitarianism. Isaiah Berlin: Developed the distinction between positive and negative liberty. Edmund Burke: Irish member of the British parliament, Burke is credited with the creation of conservative thought. Burke's Reflections on the Revolution in France is the most popular of his writings where he denounced the French revolution. Burke was one of the biggest supporters of the American Revolution. Chanakya: Wrote influential text Arthashastra, some of earliest political thinkers in Asian history. Noam Chomsky: He is widely recognized as having helped to spark the cognitive revolution in the human sciences, contributing to the development of a new cognitivistic framework for the study of language and the mind. Chomsky is a leading critic of U.S. foreign policy, neoliberalism and contemporary state capitalism, the Israeli–Palestinian conflict, and mainstream news media. His ideas have proven highly influential in the anti-capitalist and anti-imperialist movements, and aligns with anarcho-syndicalism and libertarian socialism. Confucius: The first thinker to relate ethics to the political order. William E. Connolly: Helped introduce postmodern philosophy into political theory, and promoted new theories of Pluralism and agonistic democracy. John Dewey: Co-founder of pragmatism and analyzed the essential role of education in the maintenance of democratic government. Han Feizi: The major figure of the Chinese Fajia (Legalist) school, advocated government that adhered to laws and a strict method of administration. Michel Foucault: Critiqued the modern conception of power on the basis of the prison complex and other prohibitive institutions, such as those that designate sexuality, madness and knowledge as the roots of their infrastructure, a critique that demonstrated that subjection is the power formation of subjects in any linguistic forum and that revolution cannot just be thought as the reversal of power between classes. Antonio Gramsci: Instigated the concept of hegemony. Argued that the state and the ruling class use culture and ideology to gain the consent of the classes they rule over. Thomas Hill Green: Modern liberal thinker and early supporter of positive freedom. Jürgen Habermas: Contemporary democratic theorist and sociologist. He has pioneered such concepts as the public sphere, communicative action, and deliberative democracy. His early work was heavily influenced by the Frankfurt School. Friedrich Hayek: He argued that central planning was inefficient because members of central bodies could not know enough to match the preferences of consumers and workers with existing conditions. Hayek further argued that central economic planning—a mainstay of socialism—would lead to a "total" state with dangerous power. He advocated free-market capitalism in which the main role of the state is to maintain the rule of law and let spontaneous order develop. G. W. F. Hegel: Emphasized the "cunning" of history, arguing that it followed a rational trajectory, even while embodying seemingly irrational forces; influenced Marx, Kierkegaard, Nietzsche, and Oakeshott. Thomas Hobbes: Generally considered to have first articulated how the concept of a social contract that justifies the actions of rulers (even where contrary to the individual desires of governed citizens), can be reconciled with a conception of sovereignty. David Hume: Hume criticized the social contract theory of John Locke and others as resting on a myth of some actual agreement. Hume was a realist in recognizing the role of force to forge the existence of states and that consent of the governed was merely hypothetical. He also introduced the concept of utility, later picked up on and developed by Jeremy Bentham. Hume also coined the 'is/ought' problem i.e. the idea that just because something is does not mean that is how it ought to be. This was very influential on normative politics Thomas Jefferson: Politician and political theorist during the American Enlightenment. Expanded on the philosophy of Thomas Paine by instrumenting republicanism in the United States. Most famous for the United States Declaration of Independence. Immanuel Kant: Argued that participation in civil society is undertaken not for self-preservation, as per Thomas Hobbes, but as a moral duty. First modern thinker who fully analyzed structure and meaning of obligation. Argued that an international organization was needed to preserve world peace. Peter Kropotkin: One of the classic anarchist thinkers and the most influential theorist of anarcho-communism. John Locke: Like Hobbes, described a social contract theory based on citizens' fundamental rights in the state of nature. He departed from Hobbes in that, based on the assumption of a society in which moral values are independent of governmental authority and widely shared, he argued for a government with power limited to the protection of personal property. His arguments may have been deeply influential to the formation of the United States Constitution. György Lukács: Hungarian Marxist theorist, aesthetician, literary historian, and critic. One of the founders of Western Marxism. In his magnum opus History and Class Consciousness, he developed the Marxist theory of class consciousness and introduced the concept of "reification". Niccolò Machiavelli: First systematic analysis of how politics necessitates expedient and evil actions. Gave an account of statecraft in a realistic point of view instead of relying on idealism. Machiavelli also relays recommendations on how to run a well ordered republican state, as he viewed them to be better forms of government than autocracies. James Madison: American politician and protege of Jefferson considered to be "Father of the Constitution" and "Father of the Bill of Rights" of the United States. As a political theorist, he believed in separation of powers and proposed a comprehensive set of checks and balances that are necessary to protect the rights of | in that the Roman Catholics thought subordinating philosophy to theology did not subject reason to revelation but in the case of contradictions, subordinated reason to faith as the Asharite of Islam. The Scholastics by combining the philosophy of Aristotle with the Christianity of St. Augustine emphasized the potential harmony inherent in reason and revelation. Perhaps the most influential political philosopher of medieval Europe was St. Thomas Aquinas who helped reintroduce Aristotle's works, which had only been transmitted to Catholic Europe through Muslim Spain, along with the commentaries of Averroes. Aquinas's use of them set the agenda, for scholastic political philosophy dominated European thought for centuries even unto the Renaissance. Some medieval political philosophers, such as Aquinas in his Summa Theologica, developed the idea that a king who is a tyrant is no king at all and could be overthrown. Others, like Nicole Oresme in his Livre de Politiques, categorically denied this right to overthrow an unjust ruler. The Magna Carta, viewed by many as a cornerstone of Anglo-American political liberty, explicitly proposes the right to revolt against the ruler for justice's sake. Other documents similar to Magna Carta are found in other European countries such as Spain and Hungary. European Renaissance During the Renaissance secular political philosophy began to emerge after about a century of theological political thought in Europe. While the Middle Ages did see secular politics in practice under the rule of the Holy Roman Empire, the academic field was wholly scholastic and therefore Christian in nature. Niccolò Machiavelli One of the most influential works during this burgeoning period was Niccolò Machiavelli's The Prince, written between 1511–12 and published in 1532, after Machiavelli's death. That work, as well as The Discourses, a rigorous analysis of classical antiquity, did much to influence modern political thought in the West. A minority (including Jean-Jacques Rousseau) interpreted The Prince as a satire meant to be given to the Medici after their recapture of Florence and their subsequent expulsion of Machiavelli from Florence. Though the work was written for the di Medici family in order to perhaps influence them to free him from exile, Machiavelli supported the Republic of Florence rather than the oligarchy of the Medici family. At any rate, Machiavelli presents a pragmatic and somewhat consequentialist view of politics, whereby good and evil are mere means used to bring about an end—i.e., the acquisition and maintenance of absolute power. Thomas Hobbes, well known for his theory of the social contract, goes on to expand this view at the start of the 17th century during the English Renaissance. Although neither Machiavelli nor Hobbes believed in the divine right of kings, they both believed in the inherent selfishness of the individual. It was necessarily this belief that led them to adopt a strong central power as the only means of preventing the disintegration of the social order. European Enlightenment During the Enlightenment period, new theories emerged about what the human was and is and about the definition of reality and the way it was perceived, along with the discovery of other societies in the Americas, and the changing needs of political societies (especially in the wake of the English Civil War, the American Revolution, the French Revolution, and the Haitian Revolution). These new theories led to new questions and insights by such thinkers as Thomas Hobbes, John Locke, Benjamin Constant and Jean-Jacques Rousseau. These theorists were driven by two basic questions: one, by what right or need do people form states; and two, what the best form for a state could be. These fundamental questions involved a conceptual distinction between the concepts of "state" and "government." It was decided that "state" would refer to a set of enduring institutions through which power would be distributed and its use justified. The term "government" would refer to a specific group of people who occupied the institutions of the state, and create the laws and ordinances by which the people, themselves included, would be bound. This conceptual distinction continues to operate in political science, although some political scientists, philosophers, historians and cultural anthropologists have argued that most political action in any given society occurs outside of its state, and that there are societies that are not organized into states that nevertheless must be considered in political terms. As long as the concept of natural order was not introduced, the social sciences could not evolve independently of theistic thinking. Since the cultural revolution of the 17th century in England, which spread to France and the rest of Europe, society has been considered subject to natural laws akin to the physical world. Political and economic relations were drastically influenced by these theories as the concept of the guild was subordinated to the theory of free trade, and Roman Catholic dominance of theology was increasingly challenged by Protestant churches subordinate to each nation-state, which also (in a fashion the Roman Catholic Church often decried angrily) preached in the vulgar or native language of each region. Free trade, as opposed to these religious theories, is a trade policy that does not restrict imports or exports. It can also be understood as the free market idea applied to international trade. In government, free trade is predominantly advocated by political parties that hold liberal economic positions while economically left-wing and nationalist political parties generally support protectionism, the opposite of free trade. However, the enlightenment was an outright attack on religion, particularly Christianity. The most outspoken critic of the church in France was François Marie Arouet de Voltaire, a representative figure of the enlightenment. Historians have described Voltaire's description of the history of Christianity as "propagandistic".Voltaire is partially responsible for the misattribution of the expression Credo quia absurdum to the Church Fathers. In a letter to Frederick II, King of Prussia, dated 5 January 1767, he wrote about Christianity: La nôtre [religion] est sans contredit la plus ridicule, la plus absurde, et la plus sanguinaire qui ait jamais infecté le monde. "Ours [i.e., the Christian religion] is assuredly the most ridiculous, the most absurd and the most bloody religion which has ever infected this world. Your Majesty will do the human race an eternal service by extirpating this infamous superstition, I do not say among the rabble, who are not worthy of being enlightened and who are apt for every yoke; I say among honest people, among men who think, among those who wish to think. ... My one regret in dying is that I cannot aid you in this noble enterprise, the finest and most respectable which the human mind can point out." After Voltaire, religion would never be the same again in France. As well, there was no spread of this doctrine within the New World and the advanced civilizations of the Aztec, Maya, Inca, Mohican, Delaware, Huron and especially the Iroquois. The Iroquois philosophy, in particular, gave much to Christian thought of the time and in many cases actually inspired some of the institutions adopted in the United States: for example, Benjamin Franklin was a great admirer of some of the methods of the Iroquois Confederacy, and much of early American literature emphasized the political philosophy of the natives. The Iroquois (/ˈɪrəkwɔɪ/ or /ˈɪrəkwɑː/) or Haudenosaunee are a historically powerful northeast Native American confederacy in North America. They were known during the colonial years to the French as the Iroquois League, and later as the Iroquois Confederacy, and to the English as the Five Nations, comprising the Mohawk, Onondaga, Oneida, Cayuga, and Seneca. After 1722, they accepted the Tuscarora people from the Southeast into their confederacy, as they were also Iroquoian-speaking, and became known as the Six Nations. John Locke John Locke in particular exemplified this new age of political theory with his work Two Treatises of Government. In it, Locke proposes a state of nature theory that directly complements his conception of how political development occurs and how it can be founded through contractual obligation. Locke stood to refute Sir Robert Filmer's paternally founded political theory in favor of a natural system based on nature in a particular given system. The theory of the divine right of kings became a passing fancy, exposed to the type of ridicule with which John Locke treated it. Unlike Machiavelli and Hobbes but like Aquinas, Locke would accept Aristotle's dictum that man seeks to be happy in a state of social harmony as a social animal. Unlike Aquinas's preponderant view on the salvation of the soul from original sin, Locke believes man's mind comes into this world as tabula rasa. For Locke, knowledge is neither innate, revealed nor based on authority but subject to uncertainty tempered by reason, tolerance and moderation. According to Locke, an absolute ruler as proposed by Hobbes is unnecessary, for natural law is based on reason and seeking peace and survival for man. John Stuart Mill John Stuart Mill's work on political philosophy begins in On Liberty, On Liberty is the most influential statement of his liberal principles. He begins by distinguishing old and new threats to liberty. The old threat to liberty is found in traditional societies in which there is rule by one (a monarchy) or a few (an aristocracy). Though one could be worried about restrictions on liberty by benevolent monarchs or aristocrats, the traditional worry is that when rulers are politically unaccountable to the governed they will rule in their own interests, rather than the interests of the governed. Mill's explicit theory of rights is introduced in Chapter V of Utilitarianism in the context of his sanction theory of duty, which is an indirect form of utilitarianism that identifies wrong actions as actions that it is useful to sanction. Mill then introduces justice as a proper part of the duty. Justice involves duties that are perfect duties—that is, duties that are correlated with rights. Justice implies something which it is not only right to do, and wrong not to do, but which some individual person can claim from us as a matter of right. These perfect duties will thus create liberty and collective freedom within a state. He uses, On Liberty to discuss gender equality in society. To Mill, Utilitarianism was the perfect tool to justify gender equality in The Subjection of Women, referring to the political, lawful and social subjection of women. When a woman was married, she entered legally binding coverture with her husband; once she married her legal existence as an individual was suspended under "marital unity". While it is easy to presume that a woman would not marry under these circumstances, being unmarried had social consequences. A woman could only advance in social stature and wealth if she had a rich husband to do the groundwork. Mill uses his Utilitarian ethics to assess how gender equality would be the best way to achieve "the greatest good for the greatest number" : "The principle that regulates the existing social relations between the two sexes … and is now one of the chief obstacles to human improvement…" The ‘chief obstacle’ to Mill relates to women's intellectual capability. The Subjection of Women looks at this in the women of society and argues that diminishing their intellectual potential wastes the knowledge and skill of half of the population; such knowledge lost could formulate ideas that could maximize pleasure for society. Benjamin Constant One of the first thinkers to go by the name of "liberal", Constant looked to Britain rather than to ancient Rome for a practical model of freedom in a large, commercial society. He drew a distinction between the "Liberty of the Ancients" and the "Liberty of the Moderns". The Liberty of the Ancients was participatory republican liberty, which gave the citizens the right to directly influence politics through debates and votes in the public assembly. In order to support this degree of participation, citizenship was a burdensome moral obligation requiring a considerable investment of time and energy. Generally, this required a sub-society of slaves to do much of the productive work, leaving the citizens free to deliberate on public affairs. Ancient Liberty was also limited to relatively small and homogenous societies, in which the people could be conveniently gathered together in one place to transact public affairs. The Liberty of the Moderns, in contrast, was based on the possession of civil liberties, the rule of law, and freedom from excessive state interference. Direct participation would be limited: a necessary consequence of the size of modern states, and also the inevitable result of having created a commercial society in which there are no slaves but almost everybody must earn a living through work. Instead, the voters would elect representatives, who would deliberate in Parliament on behalf of the people and would save citizens from the necessity of daily political involvement. Moreover, Constant believed that, in the modern world, commerce was superior to war. He attacked Napoleon's martial appetite, on the grounds that it was illiberal and no longer suited to modern commercial social organization. Ancient Liberty tended to be warlike, whereas a state organized on the principles of Modern Liberty would be at peace with all peaceful nations. Thomas Hobbes The main practical conclusion of Hobbes' political theory is that state or society can not be secure unless at the disposal of an absolute sovereign. From this follows the view that no individual can hold rights of property against the sovereign, and that the sovereign may therefore take the goods of its subjects without their consent. In Leviathan, Hobbes set out his doctrine of the foundation of states and legitimate governments and creating an objective science of morality. Much of the book is occupied with demonstrating the necessity of a strong central authority to avoid the evil of discord and civil war. Beginning from a mechanistic understanding of human beings and their passions, Hobbes postulates what life would be like without government, a condition which he calls the state of nature. In that state, each person would have a right, or license, to everything in the world. This, Hobbes argues, would lead to a "war of all against all". Jean-Jacques Rousseau The Social Contract outlines the basis for a legitimate political order within a framework of classical republicanism. Published in 1762, it became one of the most influential works of political philosophy in the Western tradition. It developed some of the ideas mentioned in earlier work, the article Économie Politique (Discourse on Political Economy), featured in Diderot's Encyclopédie. The treatise begins with the dramatic opening lines, "Man is born free, and everywhere he is in chains. Those who think themselves the masters of others are indeed greater slaves than they." Rousseau claimed that the state of nature was a primitive condition without law or morality, which human beings left for the benefits and necessity of cooperation. As society developed, the division of labor and private property required the human race to adopt institutions of law. In the degenerate phase of society, man is prone to be in frequent competition with his fellow men while also becoming increasingly dependent on them. This double pressure threatens both his survival and his freedom. Industrialization and the modern era The Marxist critique of capitalism—developed with Friedrich Engels—was, alongside liberalism and fascism, one of the defining ideological movements of the twentieth century. The industrial revolution produced a parallel revolution in political thought. Urbanization and capitalism greatly reshaped society. During this same period, the socialist movement began to form. In the mid-19th century, Marxism was developed, and socialism in general gained increasing popular support, mostly from the urban working class. Without breaking entirely from the past, Marx established principles that would be used by future revolutionaries of the 20th century namely Vladimir Lenin, Mao Zedong, Ho Chi Minh, and Fidel Castro. Though Hegel's philosophy of history is similar to Immanuel Kant's, and Karl Marx's theory of revolution towards the common good is partly based on Kant's view of history—Marx declared that he was turning Hegel's dialectic, which was "standing on its head", "the right side up again". Unlike Marx who believed in historical materialism, Hegel believed in the Phenomenology of Spirit. By the late 19th century, socialism and trade unions were established members of the political landscape. In addition, the various branches of anarchism, with thinkers such as Mikhail Bakunin, Pierre-Joseph Proudhon or Peter Kropotkin, and syndicalism also gained some prominence. In the Anglo-American world, anti-imperialism and pluralism began gaining currency at the turn of the 20th century. World War I was a watershed event in human history, changing views of governments and politics. The Russian Revolution of 1917 (and similar, albeit less successful, revolutions in many other European countries) brought communism—and in particular the political theory of Leninism, but also on a smaller level Luxemburgism (gradually)—on the world stage. At the same time, social democratic parties won elections and formed governments for the first time, often as a result of the introduction of universal suffrage. Contemporary In a 1956 American Political Science Review report authored by Harry Eckstein, political philosophy as a discipline had utility in two ways: the utility of political philosophy might be found either in the intrinsic ability of the best of past political thought to sharpen the wits of contemporary political thinkers, much as any difficult intellectual exercise sharpens the mind and deepens the imagination, or in the ability of political philosophy to serve as a thought-saving device by providing the political scientist with a rich source of concepts, models, insights, theories, and methods.From the end of World War II until 1971, when John Rawls published A Theory of Justice, political philosophy declined in the Anglo-American academic world, as analytic philosophers expressed skepticism about the possibility that normative judgments had cognitive content, and political science turned toward statistical methods and behavioralism. In continental Europe, on the other hand, the postwar decades saw a huge blossoming of political philosophy, with Marxism dominating the field. This was the time of Jean-Paul Sartre and Louis Althusser; and the victories of Mao Zedong in China and Fidel Castro in Cuba, as well as the events of May 1968, led to increased interest in revolutionary ideology, especially by the New Left. A number of continental European émigrés to Britain and the United States—including Karl Popper, Friedrich Hayek, Leo Strauss, Hannah Arendt, Isaiah Berlin, Eric Voegelin and Judith Shklar—encouraged continued study in political philosophy in the Anglo-American world, but in the 1950s and 1960s, they and their students remained at odds with the analytic establishment. Communism remained an important focus especially during the 1950s and 1960s. Colonialism and racism were important issues that arose. In general, there was a marked trend towards a pragmatic approach to political issues, rather than a philosophical one. Much academic debate regarded one or both of two pragmatic topics: how (or whether) to apply utilitarianism to problems of political policy, or how (or whether) to apply economic models (such as rational choice theory) to political issues. The rise of feminism, LGBT social movements and the end of colonial rule and of the political exclusion of such minorities as African Americans and sexual minorities in the developed world has led to feminist, postcolonial, and multicultural thought becoming significant. This led to a challenge to the social contract by philosophers Charles W. Mills in his book The Racial Contract and Carole Pateman in her book The Sexual Contract that the social contract excluded persons of colour and women respectively. In Anglo-American academic political philosophy, the publication of John Rawls's A Theory of Justice in 1971 is considered a milestone. Rawls used a thought experiment, the original position, in which representative parties choose principles of justice for the basic structure of society from behind a veil of ignorance. Rawls also offered a criticism of utilitarian approaches to questions of political justice. Robert Nozick's 1974 book Anarchy, State, and Utopia, which won a National Book Award, responded to Rawls from a libertarian perspective and gained academic respectability for libertarian viewpoints. Contemporaneously with the rise of analytic ethics in Anglo-American thought, in Europe, several new lines of philosophy directed at the critique of existing societies arose between the 1950s and 1980s.

including a major earthquake and tsunami in 1918 and several hurricanes, as well as the Great Depression, impoverished the island during the first few decades under U.S. rule. Some political leaders, such as Pedro Albizu Campos, who led the Puerto Rican Nationalist Party, demanded a change in relations with the United States. He organized a protest at the University of Puerto Rico in 1935, in which four were killed by police. In 1936, U.S. senator Millard Tydings introduced a bill supporting independence for Puerto Rico; he had previously co-sponsored the Tydings–McDuffie Act, which provided independence to the Philippines following a 10-year transition period of limited autonomy. While virtually all Puerto Rican political parties supported the bill, it was opposed by Luis Muñoz Marín of the Liberal Party of Puerto Rico, leading to its defeat In 1937, Albizu Campos' party organized a protest in Ponce. The Insular Police, similar to the National Guard, opened fire upon unarmed cadets and bystanders alike. The attack on unarmed protesters was reported by U.S. Congressman Vito Marcantonio and confirmed by a report from the Hays Commission, which investigated the events, led by Arthur Garfield Hays, counsel to the American Civil Liberties Union. Nineteen people were killed and over 200 were badly wounded, many shot in the back while running away. The Hays Commission declared it a massacre and police mob action, and it has since become known as the Ponce massacre. In the aftermath, on 2 April 1943, Tydings introduced another bill in Congress calling for independence for Puerto Rico, though it was again defeated. During the latter years of the Roosevelt–Truman administrations, the internal governance of the island was changed in a compromise reached with Luis Muñoz Marín and other Puerto Rican leaders. In 1946, President Truman appointed the first Puerto Rican-born governor, Jesús T. Piñero. Since 2007, the Puerto Rico State Department has developed a protocol to issue certificates of Puerto Rican citizenship to Puerto Ricans. In order to be eligible, applicants must have been born in Puerto Rico, born outside of Puerto Rico to a Puerto Rican-born parent, or be an American citizen with at least one year of residence in Puerto Rico. U.S. unincorporated organized territory with commonwealth constitution In 1947, the U.S. Congress passed the Elective Governor Act, signed by President Truman, allowing Puerto Ricans to vote for their own governor. The first elections under this act were held the following year, on 2 November 1948. On 21 May 1948, a bill was introduced before the Puerto Rican Senate which would restrain the rights of the independence and Nationalist movements on the island. The Senate, controlled by the Partido Popular Democrático (PPD) and presided by Luis Muñoz Marín, approved the bill that day. This bill, which resembled the anti-communist Smith Act passed in the United States in 1940, became known as the Ley de la Mordaza (Gag Law) when the U.S.-appointed governor of Puerto Rico, Jesús T. Piñero, signed it into law on 10 June 1948. Under this new law, it would be a crime to print, publish, sell, or exhibit any material intended to paralyze or destroy the insular government; or to organize any society, group or assembly of people with a similar destructive intent. It made it illegal to sing a patriotic song, and reinforced the 1898 law that had made it illegal to display the flag of Puerto Rico, with anyone found guilty of disobeying the law in any way being subject to a sentence of up to ten years imprisonment, a fine of up to US$10,000 (), or both. According to Dr. Leopoldo Figueroa, the only non-PPD member of the Puerto Rico House of Representatives, the law was repressive and in violation of the First Amendment of the U.S. Constitution, which guarantees Freedom of Speech. He asserted that the law as such was a violation of the civil rights of the people of Puerto Rico. The law was repealed in 1957. In the November 1948 election, Muñoz Marín became the first popularly elected governor of Puerto Rico, replacing U.S.-appointed Piñero on 2 January 1949. Estado Libre Asociado In 1950, the U.S. Congress granted Puerto Ricans the right to organize a constitutional convention via a referendum; voters could either accept or reject a proposed U.S. law that would organize Puerto Rico as a "commonwealth" under continued U.S. sovereignty. The Constitution of Puerto Rico was approved by the constitutional convention on 6 February 1952, and by 82% of voters in a March referendum. It was modified and ratified by the U.S. Congress, approved by President Truman on 3 July of that year, and proclaimed by Governor Muñoz Marín on 25 July 1952—the anniversary of the landing of U.S. troops in the Puerto Rican Campaign of the Spanish–American War, until then celebrated as an annual Puerto Rico holiday. Puerto Rico adopted the name of Estado Libre Asociado de Puerto Rico (literally "Associated Free State of Puerto Rico"), officially translated into English as Commonwealth, for its body politic. Congress would continue governing fundamental aspects of Puerto Rican society, including citizenship, currency, the postal service, foreign policy, military defense, commerce and finance, and other matters. In 1967 Puerto Rico's Legislative Assembly polled the political preferences of the Puerto Rican electorate by passing a plebiscite act that provided for a vote on the status of Puerto Rico. This constituted the first plebiscite by the Legislature for a choice among three status options (commonwealth, statehood, and independence). In subsequent plebiscites organized by Puerto Rico held in 1993 and 1998 (without any formal commitment on the part of the U.S. government to honor the results), the current political status failed to receive majority support. In 1993, Commonwealth status won by a plurality of votes (48.6% versus 46.3% for statehood), while the "none of the above" option, which was the Popular Democratic Party-sponsored choice, won in 1998 with 50.3% of the votes (versus 46.5% for statehood). Disputes arose as to the definition of each of the ballot alternatives, and Commonwealth advocates, among others, reportedly urged a vote for "none of the above". In 1950, the U.S. Congress approved Public Law 600 (P.L. 81-600), which allowed for a democratic referendum in Puerto Rico to determine whether Puerto Ricans desired to draft their own local constitution. This Act was meant to be adopted in the "nature of a compact". It required congressional approval of the Puerto Rico Constitution before it could go into effect, and repealed certain sections of the Organic Act of 1917. The sections of this statute left in force were entitled the Puerto Rican Federal Relations Act. U.S. Secretary of the Interior Oscar L. Chapman, under whose Department resided responsibility of Puerto Rican affairs, clarified the new commonwealth status in this manner: On 30 October 1950, Pedro Albizu Campos and other nationalists led a three-day revolt against the United States in various cities and towns of Puerto Rico, in what is known as the Puerto Rican Nationalist Party Revolts of the 1950s. The most notable occurred in Jayuya and Utuado. In the Jayuya revolt, known as the "Jayuya Uprising", the Puerto Rican governor declared martial law, and attacked the insurgents in Jayuya with infantry, artillery and bombers under control of the Puerto Rican commander. The "Utuado Uprising" culminated in what is known as the Utuado massacre. Albizu Campos served many years in a federal prison in Atlanta, for seditious conspiracy to overthrow the U.S. government in Puerto Rico. On 1 November 1950, Puerto Rican nationalists from New York City, Griselio Torresola and Oscar Collazo, attempted to assassinate President Harry S. Truman at his temporary residence of Blair House. Torresola was killed during the attack, but Collazo was wounded and captured. He was convicted of murder and sentenced to death, but President Truman commuted his sentence to life. After Collazo served 29 years in a federal prison, President Jimmy Carter commuted his sentence to time served and he was released in 1979. During the 1950s and 1960s, Puerto Rico experienced rapid industrialization, due in large part to Operación Manos a la Obra ("Operation Bootstrap"), an offshoot of FDR's New Deal. It was intended to transform Puerto Rico's economy from agriculture-based to manufacturing-based to provide more jobs. Puerto Rico has become a major tourist destination, as well as a global center for pharmaceutical manufacturing. 21st century On 15 July 2009, the United Nations Special Committee on Decolonization approved a draft resolution calling on the government of the United States to expedite a process that would allow the Puerto Rican people to exercise fully their inalienable right to self-determination and independence. On 6 November 2012, a two-question referendum took place, simultaneous with the general elections. The first question, voted on in August, asked voters whether they wanted to maintain the current status under the territorial clause of the U.S. Constitution. 54% voted against the status quo, effectively approving the second question to be voted on in November. The second question posed three alternate status options: statehood, independence, or free association. 61.16% voted for statehood, 33.34% for a sovereign free associated state, and 5.49% for independence. On 30 June 2016, President Obama signed into law H.R. 5278: PROMESA, establishing a Control Board over the Puerto Rican government. This board will have a significant degree of federal control involved in its establishment and operations. In particular, the authority to establish the control board derives from the federal government's constitutional power to "make all needful rules and regulations" regarding U.S. territories; The president would appoint all seven voting members of the board; and the board would have broad sovereign powers to effectively overrule decisions by Puerto Rico's legislature, governor, and other public authorities. Puerto Rico held its statehood referendum during the 3 November 2020 general elections; the ballot asked one question: "Should Puerto Rico be admitted immediately into the Union as a State?" The results showed that 52 percent of Puerto Rico voters answered yes. Environment Puerto Rico consists of the main island of Puerto Rico and various smaller islands, including Vieques, Culebra, Mona, Desecheo, and Caja de Muertos. Of these five, only Culebra and Vieques are inhabited year-round. Mona, which has played a key role in maritime history, is uninhabited most of the year except for employees of the Puerto Rico Department of Natural Resources. There are many other even smaller islets, like Monito, which is near to Mona, Isla de Cabras and La Isleta de San Juan, both located on the San Juan Bay. The latter is the only inhabited islet with communities like Old San Juan and Puerta de Tierra, and connected to the main island by bridges. The Commonwealth of Puerto Rico has an area of , of which is land and is water. Puerto Rico is larger than Delaware and Rhode Island. The maximum length of the main island from east to west is , and the maximum width from north to south is . Puerto Rico is the smallest of the Greater Antilles. It is 80% of the size of Jamaica, just over 18% of the size of Hispaniola and 8% of the size of Cuba, the largest of the Greater Antilles. The island is mostly mountainous with large coastal areas in the north and south. The main mountain range is called "La Cordillera Central" (The Central Range). The highest elevation in Puerto Rico, Cerro de Punta , is located in this range. Another important peak is El Yunque, one of the highest in the Sierra de Luquillo at the El Yunque National Forest, with an elevation of . Puerto Rico has 17 lakes, all man-made, and more than 50 rivers, most originating in the Cordillera Central. Rivers in the northern region of the island are typically longer and of higher water flow rates than those of the south, since the south receives less rain than the central and northern regions. Puerto Rico is composed of Cretaceous to Eocene volcanic and plutonic rocks, overlain by younger Oligocene and more recent carbonates and other sedimentary rocks. Most of the caverns and karst topography on the island occurs in the northern region in the carbonates. The oldest rocks are approximately years old (Jurassic) and are located at Sierra Bermeja in the southwest part of the island. They may represent part of the oceanic crust and are believed to come from the Pacific Ocean realm. Puerto Rico lies at the boundary between the Caribbean and North American plates and is being deformed by the tectonic stresses caused by their interaction. These stresses may cause earthquakes and tsunamis. These seismic events, along with landslides, represent some of the most dangerous geologic hazards in the island and in the northeastern Caribbean. The 1918 San Fermín earthquake occurred on , 1918, and had an estimated magnitude of 7.5 on the Richter scale. It originated off the coast of Aguadilla, several kilometers off the northern coast, and was accompanied by a tsunami. It caused extensive property damage and widespread losses, damaging infrastructure, especially bridges. It resulted in an estimated 116 deaths and $4 million in property damage. The failure of the government to move rapidly to provide for the general welfare contributed to political activism by opponents and eventually to the rise of the Puerto Rican Nationalist Party. On 7 January 2020, the country experienced its second largest earthquake, estimated at magnitude 6.4. Economic losses were estimated to be more than $3.1 billion. The Puerto Rico Trench, the largest and deepest trench in the Atlantic, is located about north of Puerto Rico at the boundary between the Caribbean and North American plates. It is long. At its deepest point, named the Milwaukee Deep, it is almost deep. Climate The climate of Puerto Rico in the Köppen climate classification is tropical rainforest. Temperatures are warm to hot year round, averaging near 85 °F (29 °C) in lower elevations and 70 °F (21 °C) in the mountains. Easterly trade winds pass across the island year round. Puerto Rico has a rainy season which stretches from April into November. The mountains of the Cordillera Central are the main cause of the variations in the temperature and rainfall that occur over very short distances. The mountains can also cause wide variation in local wind speed and direction due to their sheltering and channeling effects adding to the climatic variation. The island has an average temperature of throughout the year, with an average minimum temperature of and maximum of . Daily temperature changes seasonally are quite small in the lowlands and coastal areas. The temperature in the south is usually a few degrees higher than those in the north and temperatures in the central interior mountains are always cooler than those on the rest of the island. Between the dry and wet season, there is a temperature change of around . This change is due mainly to the warm waters of the tropical Atlantic Ocean, which significantly modify cooler air moving in from the north and northwest. Coastal waters temperatures around the years are about in February to in August. The highest temperature ever recorded was at Arecibo, while the lowest temperature ever recorded was in the mountains at Adjuntas, Aibonito, and Corozal. The average yearly precipitation is . Hurricanes Puerto Rico experiences the Atlantic hurricane season, similar to the remainder of the Caribbean Sea and North Atlantic oceans. On average, a quarter of its annual rainfall is contributed from tropical cyclones, which are more prevalent during periods of La Niña than El Niño. A cyclone of tropical storm strength passes near Puerto Rico, on average, every five years. A hurricane passes in the vicinity of the island, on average, every seven years. Since 1851, the Lake Okeechobee Hurricane (also known as the San Felipe Segundo hurricane in Puerto Rico) of September 1928 is the only hurricane to make landfall as a Category 5 hurricane. In the busy 2017 Atlantic hurricane season, Puerto Rico avoided a direct hit by the Category 5 Hurricane Irma on 6 September 2017, as it passed about north of Puerto Rico, but high winds caused a loss of electrical power to some one million residents. Almost 50% of hospitals were operating with power provided by generators. The Category 4 Hurricane Jose, as expected, veered away from Puerto Rico. A short time later, the devastating Hurricane Maria made landfall on Puerto Rico on Wednesday, 20 September, near the Yabucoa municipality at 10:15 UTC (6:15 am local time) as a high-end Category 4 hurricane with sustained winds of 155 mph (250 km/h), powerful rains and widespread flooding causing tremendous destruction, including the electrical grid, which would remain out for 4–6 months in many portions of the island. Hurricane Dorian was the third hurricane in three years to hit Puerto Rico in 2019. The recovering infrastructure from the 2017 hurricanes, as well as new governor Wanda Vázquez Garced, were put to the test against a potential humanitarian crisis. Tropical Storm Karen also caused impacts to Puerto Rico during 2019. Climate change Biodiversity Puerto Rico is home to three terrestrial ecoregions: Puerto Rican moist forests, Puerto Rican dry forests, and Greater Antilles mangroves. Species endemic to the archipelago number 239 plants, 16 birds and 39 amphibians/reptiles, recognized as of 1998. Most of these (234, 12 and 33 respectively) are found on the main island. The most recognizable endemic species and a symbol of Puerto Rican pride is the coquí, a small frog easily identified by the sound of its call, from which it gets its name. Most coquí species (13 of 17) live in the El Yunque National Forest, a tropical rainforest in the northeast of the island previously known as the Caribbean National Forest. El Yunque is home to more than 240 plants, 26 of which are endemic to the island. It is also home to 50 bird species, including the critically endangered Puerto Rican amazon. Across the island in the southwest, the of dry land at the Guánica Commonwealth Forest Reserve contain over 600 uncommon species of plants and animals, including 48 endangered species and 16 endemic to Puerto Rico. Puerto Rico has three bioluminescent bays: rare bodies of water occupied by microscopic marine organisms that glow when touched. However, tourism, pollution, and hurricanes have threatened the organisms. Demographics The population of Puerto Rico has been shaped by initial Amerindian settlement, European colonization, slavery, economic migration, and Puerto Rico's status as unincorporated territory of the United States. Population makeup The population of Puerto Rico according to the 2020 census is 3,285,874, an 11.8% decrease since the 2010 United States Census. From 2000 to 2010, the population declined for the first time in census history for Puerto Rico, from 3,808,610 to 3,725,789. Continuous European immigration and high natural increase helped the population of Puerto Rico grow from 155,426 in 1800 to almost a million by the close of the 19th century. A census conducted by royal decree on 30 September 1858, gave the following totals of the Puerto Rican population at that time: 341,015 were free colored; 300,430 were white; and 41,736 were slaves. A census in 1887 found a population of around 800,000, of which 320,000 were black. During the 19th century, hundreds of families arrived in Puerto Rico, primarily from the Canary Islands and Andalusia, but also from other parts of Spain such as Catalonia, Asturias, Galicia and the Balearic Islands and numerous Spanish loyalists from Spain's former colonies in South America. Settlers from outside Spain also arrived in the islands, including from Corsica, France, Lebanon, China, Portugal, Ireland, Scotland, Germany and Italy. This immigration from non-Hispanic countries was the result of the Real Cedula de Gracias de 1815 ("Royal Decree of Graces of 1815"), which allowed European Catholics to settle in the island with land allotments in the interior of the island, provided they paid taxes and continued to support the Catholic Church. Between 1960 and 1990, the census questionnaire in Puerto Rico did not ask about race or ethnicity. The 2000 United States Census included a racial self-identification question in Puerto Rico. According to the census, most Puerto Ricans identified as white and Latino; few identified as black or some other race. Population genetics A group of researchers from Puerto Rican universities conducted a study of mitochondrial DNA that revealed that the modern population of Puerto Rico has a high genetic component of Taíno and Guanche (especially of the island of Tenerife). Other studies show Amerindian ancestry in addition to the Taíno. One genetic study on the racial makeup of Puerto Ricans (including all races) found them to be roughly around 61% West Eurasian/North African (overwhelmingly of Spanish provenance), 27% Sub-Saharan African and 11% Native American. Another genetic study, from 2007, claimed that "the average genomewide individual (i.e., Puerto Rican) ancestry proportions have been estimated as 66%, 18%, and 16%, for European, West African, and Native American, respectively." Another study estimates 63.7% European, 21.2% (Sub-Saharan) African, and 15.2% Native American; European ancestry is more prevalent in the West and in Central Puerto Rico, African in Eastern Puerto Rico, and Native American in Northern Puerto Rico. Literacy A Pew Research survey indicated an adult literacy rate of 90.4% in 2012 based on data from the United Nations. Life expectancy Puerto Rico has a life expectancy of approximately 81.0 years according to the CIA World Factbook, an improvement from 78.7 years in 2010. This means Puerto Rico has the second-highest life expectancy in the United States, if territories are taken into account. Immigration and emigration As of 2019, Puerto Rico was home to 100,000 permanent legal residents. The vast majority of recent immigrants, both legal and illegal, come from the Dominican Republic and Haiti. Other major sources of recent immigrants include Cuba, Mexico, Colombia, Panama, Jamaica, Venezuela, Spain, and Nigeria. Additionally, there are many non-Puerto Rican U.S. citizens settling in Puerto Rico from the mainland United States and the U.S. Virgin Islands, as well as Nuyoricans and other stateside Puerto Ricans coming back. Most recent immigrants settle in and around San Juan. Emigration is a major part of contemporary Puerto Rican history. Starting soon after World War II, poverty, cheap airfares, and promotion by the island government caused waves of Puerto Ricans to move to the United States mainland, particularly to the northeastern states and nearby Florida. This trend continued even as Puerto Rico's economy improved and its birth rate declined. Puerto Ricans continue to follow a pattern of "circular migration", with some migrants returning to the island. In recent years, the population has declined markedly, falling nearly 1% in 2012 and an additional 1% (36,000 people) in 2013 due to a falling birthrate and emigration. The impact of hurricanes Maria and Irma in 2017, combined with the unincorporated territory's worsening economy, led to its greatest population decline since the U.S. acquired the archipelago. According to the 2010 Census, the number of Puerto Ricans living in the United States outside of Puerto Rico far exceeds those living in Puerto Rico. Emigration exceeds immigration. As those who leave tend to be better educated than those who remain, this accentuates the drain on Puerto Rico's economy. Based on 1 July 2019 estimate by the U.S. Census Bureau, the population of the Commonwealth had declined by 532,095 people since the 2010 Census data had been tabulated. Population distribution The most populous city is the capital, San Juan, with 318,441 people based on a 2019 estimate by the Census Bureau. Other major cities include Bayamón, Carolina, Ponce, and Caguas. Of the ten most populous cities on the island, eight are located within what is considered San Juan's metropolitan area, while the other two are located in the south (Ponce) and west (Mayagüez) of the island. Languages The official languages of the executive branch of government of Puerto Rico are Spanish and English, with Spanish being the primary language. Spanish is, and has been, the only official language of the entire Commonwealth judiciary system, despite a 1902 English-only language law. However, all official business of the U.S. District Court for the District of Puerto Rico is conducted in English. English is the primary language of less than 10% of the population. Spanish is the dominant language of business, education and daily life on the island, spoken by nearly 95% of the population. Out of people age five and older, 94.3% speak only Spanish at home, 5.5% speak English, and 0.2% speak other languages. In Puerto Rico, public school instruction is conducted almost entirely in Spanish. There have been pilot programs in about a dozen of the over 1,400 public schools aimed at conducting instruction in English only. Objections from teaching staff are common, perhaps because many of them are not fully fluent in English. English is taught as a second language and is a compulsory subject from elementary levels to high school. The languages of the deaf community are American Sign Language and its local variant, Puerto Rican Sign Language. The Spanish of Puerto Rico has evolved into having many idiosyncrasies in vocabulary and syntax that differentiate it from the Spanish spoken elsewhere. As a product of Puerto Rican history, the island possesses a unique Spanish dialect. Puerto Rican Spanish utilizes many Taíno words, as well as English words. The largest influence on the Spanish spoken in Puerto Rico is that of the Canary Islands. Taíno loanwords are most often used in the context of vegetation, natural phenomena, and native musical instruments. Similarly, words attributed to primarily West African languages were adopted in the contexts of foods, music, and dances, particularly in coastal towns with concentrations of descendants of Sub-Saharan Africans. Religion The Catholic faith was brought by Spanish colonists and gradually became the dominant religion in Puerto Rico. The first dioceses in the Americas, including that of Puerto Rico, were authorized by Pope Julius II in 1511. In 1512, priests were established for the parochial churches. By 1759, there was a priest for each church. One Pope, John Paul II, visited Puerto Rico in October 1984. All municipalities in Puerto Rico have at least one Catholic church, most of which are located at the town center, or plaza. Protestantism, which was suppressed under the Spanish Catholic regime, has reemerged under United States rule, making contemporary Puerto Rico more interconfessional than in previous centuries, although Catholicism continues to be the dominant religion. The first Protestant church, Iglesia de la Santísima Trinidad, was established in Ponce by the Anglican Diocese of Antigua in 1872. It was the first non-Catholic church in the entire Spanish Empire in the Americas. Pollster Pablo Ramos stated in 1998 that the population was 38% Roman Catholic, 28% Pentecostal, and 18% were members of independent churches, which would give a Protestant percentage of 46% if the last two populations are combined. Protestants collectively added up to almost two million people. Another researcher gave a more conservative assessment of the proportion of Protestants: Puerto Rico, by virtue of its long political association with the United States, is the most Protestant of Latin American countries, with a Protestant population of approximately 33 to 38 percent, the majority of whom are Pentecostal. David Stoll calculates that if we extrapolate the growth rates of evangelical churches from 1960 to 1985 for another twenty-five years Puerto Rico will become 75 percent evangelical. (Ana Adams: "Brincando el Charco..." in Power, Politics and Pentecostals in Latin America, Edward Cleary, ed., 1997. p. 164). An Associated Press article in March 2014 stated that "more than 70 percent of whom identify themselves as Catholic" but provided no source for this information. The CIA World Factbook reports that 85% of the population of Puerto Rico identifies as Roman Catholic, while 15% identify as Protestant and Other. Neither a date or a source for that information is provided and may not be recent. A 2013 Pew Research survey found that only about 45% of Puerto Rican adults identified themselves as Catholic, 29% as Protestant and 20% as unaffiliated with a religion. The people surveyed by Pew consisted of Puerto Ricans living in the 50 states and DC and may not be indicative of those living in the Commonwealth. By 2014, a Pew Research report, with the sub-title Widespread Change in a Historically Catholic Region, indicated that only 56% of Puerto Ricans were Catholic and that 33% were Protestant; this survey was completed between October 2013 and February 2014. An Eastern Orthodox community, the Dormition of the Most Holy Theotokos / St. Spyridon's Church is located in Trujillo Alto, and serves the small Orthodox community. This affiliation accounted for under 1% of the population in 2010 according to the Pew Research report. In 1940, Juanita García Peraza founded the Mita Congregation, the first religion of Puerto Rican origin. Taíno religious practices have been rediscovered/reinvented to a degree by a handful of advocates. Similarly, some aspects of African religious traditions have been kept by some adherents. African slaves brought and maintained various ethnic African religious practices associated with different peoples; in particular, the Yoruba beliefs of Santería and/or Ifá, and the Kongo-derived Palo Mayombe. Some aspects were absorbed into syncretic Christianity. In 1952, a handful of American Jews established the island's first synagogue; this religion accounts for under 1% of the population in 2010 according to the Pew Research report. The synagogue, called Sha'are Zedeck, hired its first rabbi in 1954. Puerto Rico has the largest Jewish community in the Caribbean, numbering 3000 people, and is the only Caribbean island in which the Conservative, Reform and Orthodox Jewish movements all are represented. In 2007, there were about 5,000 Muslims in Puerto Rico, representing about 0.13% of the population. Eight mosques are located throughout the island, with most Muslims living in Río Piedras and Caguas; most Muslims are of Palestinian and Jordanian descent. There is also a Baháʼí community. In 2015, the 25,832 Jehovah's Witnesses represented about 0.70% of the population, with 324 congregations. The Padmasambhava Buddhist Center, whose followers practice Tibetan Buddhism, as well as Nichiren Buddhism have branches in Puerto Rico. There are several atheist activist and educational organizations, and an atheistic parody religion called the Pastafarian Church of Puerto Rico. An ISKCON temple in Gurabo is devoted to Krishna Consciousness, with two preaching centers in the metropolitan area. Government Puerto Rico has a republican form of government based on the American model, with separation of powers subject to the jurisdiction and sovereignty of the United States. All governmental powers are delegated by the United States Congress, with the head of state being president of the United States. As an unincorporated territory, Puerto Rico lacks full protection under the United States Constitution. The government of Puerto Rico is composed of three branches. The executive is headed by the governor, currently Pedro Pierluisi Urrutia. The legislative branch consists of the bicameral Legislative Assembly, made up of a Senate as its upper chamber and a House of Representatives as its lower chamber; the Senate is headed by a president, currently José Luis Dalmau, while the House is headed by the speaker of the House, currently Tatito Hernández. The governor and legislators are elected by popular vote every four years, with the last election held in November 2020. The judicial branch is headed by the chief justice of the Supreme Court of Puerto Rico, currently Maite Oronoz Rodríguez. Members of the judiciary are appointed by the governor with the advice and consent of the Senate. Puerto Rico is represented in the U.S. Congress by a nonvoting delegate, the resident commissioner, currently Jenniffer González. Current congressional rules have removed the commissioner's power to vote in the Committee of the Whole, but the commissioner can vote in committee. Puerto Rican elections are governed by the Federal Election Commission and the State Elections Commission of Puerto Rico. Residents of Puerto Rico, including other U.S. citizens, cannot vote in U.S. presidential elections, but can vote in primaries. Puerto Ricans who become residents of a U.S. state or the District of Columbia can vote in presidential elections. Puerto Rico has 8 senatorial districts, 40 representative districts and 78 municipalities; there are no first-order administrative divisions as defined by the U.S. government. Municipalities are subdivided into wards or barrios, and those into sectors. Each municipality has a mayor and a municipal legislature elected for a four-year term. The municipality of San Juan is the oldest, founded in 1521; the next earliest settlements are San Germán in 1570, Coamo in 1579, Arecibo in 1614, Aguada in 1692 and Ponce in 1692. Increased settlement in the 18th century saw 30 more communities established, following 34 in the 19th centuryl six were founded in the 20th century, the most recent being Florida in 1971. Political parties and elections Since 1952, Puerto Rico has had three main political parties: the Popular Democratic Party (PPD in Spanish), the New Progressive Party (PNP in Spanish) and the Puerto Rican Independence Party (PIP). The three parties stand for different political status. The PPD, for example, seeks to maintain the island's status with the U.S. as a commonwealth, while the PNP, on the other hand, seeks to make Puerto Rico a state of the United States. The PIP, in contrast, seeks a complete separation from the United States by seeking to make Puerto Rico a sovereign nation. In terms of party strength, the PPD and PNP usually hold about 47% of the vote each while the PIP holds only about 5%. After 2007, other parties emerged on the island. The first, the Puerto Ricans for Puerto Rico Party (PPR in Spanish) was registered that same year. The party claims that it seeks to address the islands' problems from a status-neutral platform. But it ceased to remain as a registered party when it failed to obtain the required number of votes in the 2008 general election. Four years later, the 2012 election saw the emergence of the Movimiento Unión Soberanista (MUS; English: Sovereign Union Movement) and the Partido del Pueblo Trabajador (PPT; English: Working People's Party) but none obtained more than 1% of the vote. Other non-registered parties include the Puerto Rican Nationalist Party, the Socialist Workers Movement, and the Hostosian National Independence Movement. Law The insular legal system is a blend of civil law and the common law systems. Puerto Rico is the only current U.S. jurisdiction whose legal system operates primarily in a language other than American English: namely, Spanish. Because the U.S. federal government operates primarily in English, all Puerto Rican attorneys must be bilingual in order to litigate in English in U.S. federal courts, and litigate federal preemption issues in Puerto Rican courts. Title 48 of the United States Code outlines the role of the United States Code to United States territories and insular areas such as Puerto Rico. After the U.S. government assumed control of Puerto Rico in 1901, it initiated legal reforms resulting in the adoption of codes of criminal law, criminal procedure, and civil procedure modeled after those then in effect in California. Although Puerto Rico has since followed the federal example of transferring criminal and civil procedure from statutory law to rules promulgated by the judiciary, several portions of its criminal law still reflect the influence of the California Penal Code. The judicial branch is headed by the chief justice of the Puerto Rico Supreme Court, which is the only appellate court required by the Constitution. All other courts are created by the Legislative Assembly of Puerto Rico. There is also a Federal District Court for Puerto Rico, and someone accused of a criminal act at the federal level may not be accused for the same act in a Commonwealth court, and vice versa, since Puerto Rico as an unincorporated territory lacks sovereignty separate from Congress as a state does. Such a parallel accusation would constitute double jeopardy. Political status The nature of Puerto Rico's political relationship with the U.S. is the subject of ongoing debate in Puerto Rico, the United States Congress, and the United Nations. Specifically, the basic question is whether Puerto Rico should remain an unincorporated territory of the U.S., become a U.S. state, or become an independent country. Within the United States Constitutionally, Puerto Rico is subject to the plenary powers of the United States Congress under the territorial clause of Article IV of the U.S. Constitution. Laws enacted at the federal level in the United States apply to Puerto Rico as well, regardless of its political status. Their residents do not have voting representation in the U.S. Congress. Like the different states of the United States, Puerto Rico lacks "the full sovereignty of an independent nation", for example, the power to manage its "external relations with other nations", which is held by the U.S. federal government. The Supreme Court of the United States has indicated that once the U.S. Constitution has been extended to an area (by Congress or the courts), its coverage is irrevocable. To hold that the political branches may switch the Constitution on or off at will would lead to a regime in which they, not this Court, say "what the law is". Puerto Ricans "were collectively made U.S. citizens" in 1917 as a result of the Jones-Shafroth Act. U.S. citizens residing in Puerto Rico cannot vote in U.S. presidential elections, though both major parties, Republican and Democratic, hold primary elections in Puerto Rico to choose delegates to vote on the parties' presidential candidates. Since Puerto Rico is an unincorporated territory (see above) and not a U.S. state, the United States Constitution does not fully enfranchise U.S. citizens residing in Puerto Rico. Only fundamental rights under the American federal constitution and adjudications are applied to Puerto Ricans. Various other U.S. Supreme Court decisions have held which rights apply in Puerto Rico and which ones do not. Puerto Ricans have a long history of service in the U.S. Armed Forces and, since 1917, they have been included in the U.S. compulsory draft whensoever it has been in effect. Though the Commonwealth government has its own tax laws, Puerto Ricans are also required to pay many kinds of U.S. federal taxes, not including the federal personal income tax for Puerto Rico-sourced income, but under only certain circumstances. In 2009, Puerto Rico paid into the U.S. Treasury. Residents of Puerto Rico pay into Social Security, and are thus eligible for Social Security benefits upon retirement. They are excluded from the Supplemental Security Income (SSI), and the island actually receives a smaller fraction of the Medicaid funding it would receive if it were a U.S. state. Also, Medicare providers receive less-than-full state-like reimbursements for services rendered to beneficiaries in Puerto Rico, even though the latter paid fully into the system. Puerto Rico's authority to enact a criminal code derives from Congress and not from local sovereignty as with the states. Thus, individuals committing a crime can only be tried in federal or territorial court, otherwise it would constitute double jeopardy and is constitutionally impermissible. In 1992, President George H. W. Bush issued a memorandum to heads of executive departments and agencies establishing the current administrative relationship between the federal government and the Commonwealth of Puerto Rico. This memorandum directs all federal departments, agencies, and officials to treat Puerto Rico administratively as if it were a state, insofar as doing so would not disrupt federal programs or operations. Many federal executive branch agencies have significant presence in Puerto Rico, just as in any state, including the Federal Bureau of Investigation, Federal Emergency Management Agency, Transportation Security Administration, Social Security Administration, and others. While Puerto Rico has its own Commonwealth judicial system similar to that of a U.S. state, there is also a U.S. federal district court in Puerto Rico, and Puerto Ricans have served as judges in that Court and in other federal courts on the U.S. mainland regardless of their residency status at the time of their appointment. Sonia Sotomayor, a New Yorker of Puerto Rican descent, serves as an associate justice of the Supreme Court of the United States. Puerto Ricans have also been frequently appointed to high-level federal positions, including serving as United States ambassadors to other nations. Foreign and intergovernmental relations Puerto Rico is subject to the Commerce and Territorial Clause of the U.S. Constitution, and is thus restricted on how it can engage with other nations, sharing the opportunities and limitations that state governments have albeit not being one. As is the case with state governments, it has established several trade agreements with other nations, particularly with Latin American countries such as Colombia and Panamá. It has also established trade promotion offices in many foreign countries, all Spanish-speaking, and within the United States itself, which now include Spain, the Dominican Republic, Panama, Colombia, Washington, D.C., New York City and Florida, and has included in the past offices in Chile, Costa Rica, and Mexico. Such agreements require permission from the U.S. Department of State; most are simply allowed by existing laws or trade treaties between the United States and other nations which supersede trade agreements pursued by Puerto Rico and different U.S. states. Puerto Rico hosts consulates from 41 countries, mainly from the Americas and Europe, with most located in San Juan. At the local level, Puerto Rico established by law that the international relations which states and territories are allowed to engage must be handled by the Department of State of Puerto Rico, an executive department, headed by the secretary of state of Puerto Rico, who also serves as the unincorporated territory's lieutenant governor. It is also charged to liaise with general consuls and honorary consuls based in Puerto Rico. The Puerto Rico Federal Affairs Administration, along with the Office of the Resident Commissioner, manages all its intergovernmental affairs before entities of or in the United States (including the federal government of the United States, local and state governments of the United States, and public or private entities in the United States). Both entities frequently assist the Department of State of Puerto Rico in engaging with Washington, D.C.-based ambassadors and federal agencies that handle Puerto Rico's foreign affairs, such as the U.S. Department of State, the Agency for International Development, and others. The current secretary of state is Larry Seilhamer Rodríguez from the New Progressive Party, while the current director of the Puerto Rico Federal Affairs Administration is Jennifer M. Stopiran also from the NPP and a member of the Republican Party of the United States. The resident commissioner of Puerto Rico, the delegate elected by Puerto Ricans to represent them before the federal government, including the U.S. Congress, sits in the United States House of Representatives, serves and votes on congressional committees, and functions in every respect as a legislator except being denied a vote on the final disposition of legislation on the House floor. The current resident commissioner is Jenniffer González-Colón, a Republican, elected in 2016. She received more votes than any other official elected in Puerto Rico that year. Many Puerto Ricans have served as United States ambassadors to different nations and international organizations, such as the Organization of American States, mostly but not exclusively in Latin America. For example, Maricarmen Aponte, a Puerto Rican and now an acting assistant secretary of state, previously served as U.S. ambassador to El Salvador. Military As it is an unincorporated territory of the United States, the defense of Puerto Rico is provided by the United States as part of the Treaty of Paris with the president of the United States as its commander-in-chief. Puerto Rico has its own National Guard, and its own state defense force, the Puerto Rico State Guard, which by local law is under the authority of the Puerto Rico National Guard. The commander-in-chief of both local forces is the governor of Puerto Rico who delegates his authority to the Puerto Rico adjutant general, currently Major General José J. Reyes. The Adjutant General, in turn, delegates the authority over the State Guard to another officer but retains the authority over the Puerto Rico National Guard | of descendants of Sub-Saharan Africans. Religion The Catholic faith was brought by Spanish colonists and gradually became the dominant religion in Puerto Rico. The first dioceses in the Americas, including that of Puerto Rico, were authorized by Pope Julius II in 1511. In 1512, priests were established for the parochial churches.

Puerto Ricans "were collectively made U.S. citizens" in 1917 as a result of the Jones-Shafroth Act. U.S. citizens residing in Puerto Rico cannot vote in U.S. presidential elections, though both major parties, Republican and Democratic, hold primary elections in Puerto Rico to choose delegates to vote on the parties' presidential candidates. Since Puerto Rico is an unincorporated territory (see above) and not a U.S. state, the United States Constitution does not fully enfranchise U.S. citizens residing in Puerto Rico. Only fundamental rights under the American federal constitution and adjudications are applied to Puerto Ricans. Various other U.S. Supreme Court decisions have held which rights apply in Puerto Rico and which ones do not. Puerto Ricans have a long history of service in the U.S. Armed Forces and, since 1917, they have been included in the U.S. compulsory draft whensoever it has been in effect. Though the Commonwealth government has its own tax laws, Puerto Ricans are also required to pay many kinds of U.S. federal taxes, not including the federal personal income tax for Puerto Rico-sourced income, but under only certain circumstances. In 2009, Puerto Rico paid into the U.S. Treasury. Residents of Puerto Rico pay into Social Security, and are thus eligible for Social Security benefits upon retirement. They are excluded from the Supplemental Security Income (SSI), and the island actually receives a smaller fraction of the Medicaid funding it would receive if it were a U.S. state. Also, Medicare providers receive less-than-full state-like reimbursements for services rendered to beneficiaries in Puerto Rico, even though the latter paid fully into the system. Puerto Rico's authority to enact a criminal code derives from Congress and not from local sovereignty as with the states. Thus, individuals committing a crime can only be tried in federal or territorial court, otherwise it would constitute double jeopardy and is constitutionally impermissible. In 1992, President George H. W. Bush issued a memorandum to heads of executive departments and agencies establishing the current administrative relationship between the federal government and the Commonwealth of Puerto Rico. This memorandum directs all federal departments, agencies, and officials to treat Puerto Rico administratively as if it were a state, insofar as doing so would not disrupt federal programs or operations. Many federal executive branch agencies have significant presence in Puerto Rico, just as in any state, including the Federal Bureau of Investigation, Federal Emergency Management Agency, Transportation Security Administration, Social Security Administration, and others. While Puerto Rico has its own Commonwealth judicial system similar to that of a U.S. state, there is also a U.S. federal district court in Puerto Rico, and Puerto Ricans have served as judges in that Court and in other federal courts on the U.S. mainland regardless of their residency status at the time of their appointment. Sonia Sotomayor, a New Yorker of Puerto Rican descent, serves as an associate justice of the Supreme Court of the United States. Puerto Ricans have also been frequently appointed to high-level federal positions, including serving as United States ambassadors to other nations. Foreign and intergovernmental relations Puerto Rico is subject to the Commerce and Territorial Clause of the U.S. Constitution, and is thus restricted on how it can engage with other nations, sharing the opportunities and limitations that state governments have albeit not being one. As is the case with state governments, it has established several trade agreements with other nations, particularly with Latin American countries such as Colombia and Panamá. It has also established trade promotion offices in many foreign countries, all Spanish-speaking, and within the United States itself, which now include Spain, the Dominican Republic, Panama, Colombia, Washington, D.C., New York City and Florida, and has included in the past offices in Chile, Costa Rica, and Mexico. Such agreements require permission from the U.S. Department of State; most are simply allowed by existing laws or trade treaties between the United States and other nations which supersede trade agreements pursued by Puerto Rico and different U.S. states. Puerto Rico hosts consulates from 41 countries, mainly from the Americas and Europe, with most located in San Juan. At the local level, Puerto Rico established by law that the international relations which states and territories are allowed to engage must be handled by the Department of State of Puerto Rico, an executive department, headed by the secretary of state of Puerto Rico, who also serves as the unincorporated territory's lieutenant governor. It is also charged to liaise with general consuls and honorary consuls based in Puerto Rico. The Puerto Rico Federal Affairs Administration, along with the Office of the Resident Commissioner, manages all its intergovernmental affairs before entities of or in the United States (including the federal government of the United States, local and state governments of the United States, and public or private entities in the United States). Both entities frequently assist the Department of State of Puerto Rico in engaging with Washington, D.C.-based ambassadors and federal agencies that handle Puerto Rico's foreign affairs, such as the U.S. Department of State, the Agency for International Development, and others. The current secretary of state is Larry Seilhamer Rodríguez from the New Progressive Party, while the current director of the Puerto Rico Federal Affairs Administration is Jennifer M. Stopiran also from the NPP and a member of the Republican Party of the United States. The resident commissioner of Puerto Rico, the delegate elected by Puerto Ricans to represent them before the federal government, including the U.S. Congress, sits in the United States House of Representatives, serves and votes on congressional committees, and functions in every respect as a legislator except being denied a vote on the final disposition of legislation on the House floor. The current resident commissioner is Jenniffer González-Colón, a Republican, elected in 2016. She received more votes than any other official elected in Puerto Rico that year. Many Puerto Ricans have served as United States ambassadors to different nations and international organizations, such as the Organization of American States, mostly but not exclusively in Latin America. For example, Maricarmen Aponte, a Puerto Rican and now an acting assistant secretary of state, previously served as U.S. ambassador to El Salvador. Military As it is an unincorporated territory of the United States, the defense of Puerto Rico is provided by the United States as part of the Treaty of Paris with the president of the United States as its commander-in-chief. Puerto Rico has its own National Guard, and its own state defense force, the Puerto Rico State Guard, which by local law is under the authority of the Puerto Rico National Guard. The commander-in-chief of both local forces is the governor of Puerto Rico who delegates his authority to the Puerto Rico adjutant general, currently Major General José J. Reyes. The Adjutant General, in turn, delegates the authority over the State Guard to another officer but retains the authority over the Puerto Rico National Guard as a whole. U.S. military installations in Puerto Rico were part of the U.S. Atlantic Command (LANTCOM after 1993 USACOM), which had authority over all U.S. military operations that took place throughout the Atlantic. Puerto Rico had been seen as crucial in supporting LANTCOM's mission until 1999, when U.S. Atlantic Command was renamed and given a new mission as United States Joint Forces Command. Puerto Rico is currently under the responsibility of United States Northern Command. Both the Naval Forces Caribbean (NFC) and the Fleet Air Caribbean (FAIR) were formerly based at the Roosevelt Roads Naval Station. The NFC had authority over all U.S. Naval activity in the waters of the Caribbean while FAIR had authority over all U.S. military flights and air operations over the Caribbean. With the closing of the Roosevelt Roads and Vieques Island training facilities, the U.S. Navy has basically exited from Puerto Rico, except for the ships that steam by, and the only significant military presence in the island is the U.S. Army at Ft Buchanan, the Puerto Rican Army and Air National Guards, and the U.S. Coast Guard. Protests over the noise of bombing practice forced the closure of the naval base. This resulted in a loss of 6,000 jobs and an annual decrease in local income of $300 million. A branch of the U.S. Army National Guard is stationed in Puerto Rico – known as the Puerto Rico Army National Guard – which performs missions equivalent to those of the Army National Guards of the different states of the United States, including ground defense, disaster relief, and control of civil unrest. The local National Guard also incorporates a branch of the U.S. Air National Guard – known as the Puerto Rico Air National Guard – which performs missions equivalent to those of the Air National Guards of each one of the U.S. states. At different times in the 20th century, the U.S. had about 25 military or naval installations in Puerto Rico, some very small ones, as well as large installations. The largest of these installations were the former Roosevelt Roads Naval Station in Ceiba, the Atlantic Fleet Weapons Training Facility (AFWTF) on Vieques, the National Guard training facility at Camp Santiago in Salinas, Fort Allen in Juana Diaz, the Army's Fort Buchanan in San Juan, the former U.S. Air Force's Ramey Air Force Base in Aguadilla, and the Puerto Rico Air National Guard's Muñiz Air National Guard Base in San Juan. The former U.S. Navy facilities at Roosevelt Roads, Vieques, and Sabana Seca have been deactivated and partially turned over to the local government. Other than U.S. Coast Guard and Puerto Rico National Guard facilities, there are only two remaining military installations in Puerto Rico: the U.S. Army's small Ft. Buchanan (supporting local veterans and reserve units) and the PRANG (Puerto Rico Air National Guard) Muñiz Air Base (the C-130 Fleet). In recent years, the U.S. Congress has considered their deactivations, but these have been opposed by diverse public and private entities in Puerto Rico – such as retired military who rely on Ft. Buchanan for the services available there. Puerto Ricans have participated in many United States military conflicts, including the American Revolution, when volunteers from Puerto Rico, Cuba, and Mexico fought the British in 1779 under the command of General Bernardo de Gálvez (1746–1786). They continue to be disproportionately represented in present-day conflicts in Iraq and Afghanistan. The most notable example is the 65th Infantry Regiment of the United States Army, nicknamed The Borinqueneers, from the original Taíno name of the island (Borinquen). The all-Puerto Rican regiment regiment participated in World War I, World War II, the Korean War, and the War on Terror; in 2014, it was awarded the Congressional Gold Medal for its heroism during the Korean War. A significant number of Puerto Ricans serve in the U.S. Armed Forced, largely as National Guard members and civilian employees. The size of the overall military-related community is estimated to be 100,000, including retired personnel. Fort Buchanan has about 4,000 military and civilian personnel. In addition, approximately 17,000 people are members of the Puerto Rico Army and Air National Guards, or the U.S. Reserve forces. Administrative divisions Unlike the vast majority of U.S. states, Puerto Rico has no first-order administrative divisions akin to counties, but has 78 municipalities or municipios as the secondary unit of administration; for U.S. Census purposes, the municipalities are considered county equivalents. Municipalities are subdivided into barrios, and those into sectors. Each municipality has a mayor and a municipal legislature elected for four-year terms, per the Autonomous Municipalities Act of 1991. Economy Puerto Rico is classified as a high income economy by the World Bank and International Monetary Fund. It is considered the most competitive economy in Latin America by the World Economic Forum and ranks highly on the Human Development Index. According to World Bank, gross national income per capita in Puerto Rico in 2020 was $21,740. Puerto Rico's economy is mainly driven by manufacturing (primarily pharmaceuticals, textiles, petrochemicals and electronics) followed by services (primarily finance, insurance, real estate and tourism); agriculture represents less than 1% of GNP. In recent years, it has also become a popular destination for MICE (meetings, incentives, conferencing, exhibitions), with a modern convention centre district overlooking the Port of San Juan. Puerto Rico's geography and political status are both determining factors for its economic prosperity, primarily due to its relatively small size; lack of natural resources and subsequent dependence on imports; and vulnberability to U.S. foreign policy and trading restrictions, particularly concerning its shipping industry. Puerto Rico experienced a recession from 2006 to 2011, interrupted by four quarters of economic growth, and entered into recession again in 2013, following growing fiscal imbalance and the expiration of the IRS Section 936 corporate incentives that the U.S. Internal Revenue Code had applied to Puerto Rico. This IRS section was critical to the economy, as it established tax exemptions for U.S. corporations that settled in Puerto Rico, and allowed their insular subsidiaries to send their earnings to the parent corporation at any time, without paying federal tax on corporate income. Puerto Rico has surprisingly been able to maintain a relatively low inflation in the past decade while maintaining a purchasing power parity per capita higher than 80% of the rest of the world. Academically, most of Puerto Rico's economic woes stem from federal regulations that expired, have been repealed, or no longer apply to Puerto Rico; its inability to become self-sufficient and self-sustainable throughout history; its highly politicized public policy which tends to change whenever a political party gains power; as well as its highly inefficient local government which has accrued a public debt equal to 68% of its gross domestic product throughout time. Puerto Rico currently has a public debt of $72.204 billion (equivalent to 103% of GNP), and a government deficit of $2.5 billion. By American standards, Puerto Rico is underdeveloped: It is poorer than Mississippi, the poorest state of the U.S., with 41% of its population below the poverty line. However, it has the highest GDP per capita in Latin America. Puerto Rico's main trading partners are the United States, Ireland, and Japan, with most products coming from East Asia, mainly China, Hong Kong, and Taiwan. Puerto Rico's dependency on oil for transportation and electricity generation, as well as its dependency on food imports and raw materials, makes Puerto Rico volatile and highly reactive to changes in the world economy and climate. Tourism Tourism in Puerto Rico is also an important part of the economy. In 2017, Hurricane Maria caused severe damage to the island and its infrastructure, disrupting tourism for many months. The damage was estimated at $100 billion. An April 2019 report indicated that by that time, only a few hotels were still closed, that life for tourists in and around the capital had, for the most part, returned to normal. By October 2019, nearly all of the popular amenities for tourists, in the major destinations such as San Juan, Ponce and Arecibo, were in operation on the island and tourism was rebounding. This was important for the economy, since tourism provides up to 10% of Puerto Rico's GDP, according to Discover Puerto Rico. The latest Discover Puerto Rico campaign started in July 2018. An April 2019 report stated that the tourism team "after hitting the one-year anniversary of the storm in September [2018], the organization began to shift towards more optimistic messaging. The "Have We Met Yet?" campaign was intended to highlight the island's culture and history, making it distinct, different from other Caribbean destinations. In 2019, Discover Puerto Rico planned to continue that campaign, including "streaming options for branded content". In late November 2019, reports indicated that 90 calls to San Juan by Royal Caribbean ships would be cancelled during 2020 and 2021. This step would mean 360,000 fewer visitors, with a loss to the island's economy of 44 million. As well, 30 ship departures from San Juan were being canceled. The rationale for this decision was discussed in a news report:The reason for the cancellations is the privatization of the cruise docks in San Juan due to much-needed maintenance that is needed. Around $250 million investment is needed to make sure cruise ships can continue to dock there in the years to come. There is an urge for governor Wanda Vazquez to not go ahead with the privatization so this news is fluid. Heavy fiscal debt load In early 2017, the Puerto Rican government-debt crisis posed serious problems for the government which was saddled with outstanding bond debt that had climbed to $70 billion. The debt had been increasing during a decade-long recession. The Commonwealth had been defaulting on many debts, including bonds, since 2015. With debt payments due, the governor was facing the risk of a government shutdown and failure to fund the managed health care system. "Without action before April, Puerto Rico's ability to execute contracts for Fiscal Year 2018 with its managed care organizations will be threatened, thereby putting at risk beginning July 1, 2017 the health care of up to 900,000 poor U.S. citizens living in Puerto Rico", according to a letter sent to Congress by the Secretary of the Treasury and the Secretary of Health and Human Services. They also said that "Congress must enact measures recommended by both Republicans and Democrats that fix Puerto Rico's inequitable health care financing structure and promote sustained economic growth." Initially, the oversight board created under PROMESA called for Puerto Rico's governor Ricardo Rosselló to deliver a fiscal turnaround plan by 28 January. Just before that deadline, the control board gave the Commonwealth government until 28 February to present a fiscal plan (including negotiations with creditors for restructuring debt) to solve the problems. A moratorium on lawsuits by debtors was extended to 31 May. It is essential for Puerto Rico to reach restructuring deals to avoid a bankruptcy-like process under PROMESA. An internal survey conducted by the Puerto Rican Economists Association revealed that the majority of Puerto Rican economists reject the policy recommendations of the Board and the Rosselló government, with more than 80% of economists arguing in favor of auditing the debt. In early August 2017, the island's financial oversight board (created by PROMESA) planned to institute two days off without pay per month for government employees, down from the original plan of four days per month; the latter had been expected to achieve $218 million in savings. Governor Rossello rejected this plan as unjustified and unnecessary. Pension reforms were also discussed including a proposal for a 10% reduction in benefits to begin addressing the $50 billion in unfunded pension liabilities. Public finances Puerto Rico has an operating budget of about U.S.$9.8 billion with expenses at about $10.4 billion, creating a structural deficit of $775 million (about 7.9% of the budget). The practice of approving budgets with a structural deficit has been done for consecutive years starting in 2000. Throughout those years, including present time, all budgets contemplated issuing bonds to cover these projected deficits rather than making structural adjustments. This practice increased Puerto Rico's cumulative debt, as the government had already been issuing bonds to balance its actual budget for four decades beginning in 1973. Projected deficits added substantial burdens to an already indebted nation which accrued a public debt of $71B or about 70% of Puerto Rico's gross domestic product. This sparked an ongoing government-debt crisis after Puerto Rico's general obligation bonds were downgraded to speculative non-investment grade ("junk status") by three credit-rating agencies. In terms of financial control, almost 9.6%—or about $1.5 billion—of Puerto Rico's central government budget expenses for FY2014 is expected to be spent on debt service. Harsher budget cuts are expected as Puerto Rico must now repay larger chunks of debts in the coming years. For practical reasons the budget is divided into two aspects: a "general budget" which comprises the assignments funded exclusively by the Department of Treasury of Puerto Rico, and the "consolidated budget" which comprises the assignments funded by the general budget, by Puerto Rico's government-owned corporations, by revenue expected from loans, by the sale of government bonds, by subsidies extended by the federal government of the United States, and by other funds. Both budgets contrast each other drastically, with the consolidated budget being usually thrice the size of the general budget; currently $29B and $9.0B respectively. Almost one out of every four dollars in the consolidated budget comes from U.S. federal subsidies while government-owned corporations compose more than 31% of the consolidated budget. The critical aspects come from the sale of bonds, which comprise 7% of the consolidated budget – a ratio that increased annually due to the government's inability to prepare a balanced budget in addition to being incapable of generating enough income to cover all its expenses. In particular, the government-owned corporations add a heavy burden to the overall budget and public debt, as none is self-sufficient. For example, in FY2011 the government-owned corporations reported aggregated losses of more than $1.3B with the Puerto Rico Highways and Transportation Authority (PRHTA) reporting losses of $409M, the Puerto Rico Electric Power Authority (PREPA; the government monopoly that controls all electricity on the island) reporting losses of $272M, while the Puerto Rico Aqueducts and Sewers Authority (PRASA; the government monopoly that controls all water utilities on the island) reported losses of $112M. Losses by government-owned corporations have been defrayed through the issuance of bonds compounding more than 40% of Puerto Rico's entire public debt today. Holistically, from FY2000–FY2010 Puerto Rico's debt grew at a compound annual growth rate (CAGR) of 9% while GDP remained stagnant. This has not always provided a long-term solution. In early July 2017 for example, the PREPA power authority was effectively bankrupt after defaulting in a plan to restructure $9 billion in bond debt; the agency planned to seek Court protection. In terms of protocol, the governor, together with the Puerto Rico Office of Management and Budget (OGP in Spanish), formulates the budget he believes is required to operate all government branches for the ensuing fiscal year. He then submits this formulation as a budget request to the Puerto Rican legislature before 1 July, the date established by law as the beginning of Puerto Rico's fiscal year. While the constitution establishes that the request must be submitted "at the beginning of each regular session", the request is typically submitted during the first week of May as the regular sessions of the legislature begin in January and it would be impractical to submit a request so far in advance. Once submitted, the budget is then approved by the legislature, typically with amendments, through a joint resolution and is referred back to the governor for his approval. The governor then either approves it or vetoes it. If vetoed, the legislature can then either refer it back with amendments for the governor's approval, or approve it without the governor's consent by two-thirds of the bodies of each chamber. Once the budget is approved, the Department of Treasury disburses funds to the Office of Management and Budget which in turn disburses the funds to the respective agencies, while the Puerto Rico Government Development Bank (the government's intergovernmental bank) manages all related banking affairs including those related to the government-owned corporations. Cost of living The cost of living in Puerto Rico is high and has increased over the past decade. Statistics used for cost of living sometimes do not take into account certain costs, such as the high cost of electricity, which has hovered in the 24¢ to 30¢ range per kilowatt/hour, two to three times the national average, increased travel costs for longer flights, additional shipping fees, and the loss of promotional participation opportunities for customers "outside the continental United States". While some online stores do offer free shipping on orders to Puerto Rico, many merchants exclude Hawaii, Alaska, Puerto Rico and other United States territories. The household median income is stated as $19,350 and the mean income as $30,463 in the U.S. Census Bureau's 2015 update. The report also indicates that 45.5% of individuals are below the poverty level. The median home value in Puerto Rico ranges from U.S.$100,000 to U.S.$214,000, while the national median home value sits at $119,600. One of the most cited contributors to the high cost of living in Puerto Rico is the Merchant Marine Act of 1920, also known as the Jones Act, which prevents foreign-flagged ships from carrying cargo between two American ports, a practice known as cabotage. Because of the Jones Act, foreign ships inbound with goods from Central and South America, Western Europe, and Africa cannot stop in Puerto Rico, offload Puerto Rico-bound goods, load mainland-bound Puerto Rico-manufactured goods, and continue to U.S. ports. Instead, they must proceed directly to U.S. ports, where distributors break bulk and send Puerto Rico-bound manufactured goods to Puerto Rico across the ocean by U.S.-flagged ships. The local government of Puerto Rico has requested several times to the U.S. Congress to exclude Puerto Rico from the Jones Act restrictions without success. The most recent measure has been taken by the 17th Legislative Assembly of Puerto Rico through R. Conc. del S. 21. These measures have always received support from all the major local political parties. In 2013 the Government Accountability Office published a report which concluded that "repealing or amending the Jones Act cabotage law might cut Puerto Rico shipping costs" and that "shippers believed that opening the trade to non-U.S.-flag competition could lower costs". The same GAO report also found that "[shippers] doing business in Puerto Rico that GAO contacted reported that the freight rates are often—although not always—lower for foreign carriers going to and from Puerto Rico and foreign locations than the rates shippers pay to |

cutoff for statistical significance. Normally, experimental techniques improve or the experiments are repeated, and this gives ever stronger evidence. If statistical significance does not improve, this typically shows the experiments have just been repeated until a success occurs due to chance variations. Personalization of issues Tight social groups and authoritarian personality, suppression of dissent and groupthink can enhance the adoption of beliefs that have no rational basis. In attempting to confirm their beliefs, the group tends to identify their critics as enemies. Assertion of a conspiracy on the part of the mainstream scientific community to suppress pseudoscientific information. Attacking the motives, character, morality, or competence of critics (See Ad hominem fallacy). Use of misleading language Creating scientific-sounding terms to persuade non-experts to believe statements that may be false or meaningless: for example, a long-standing hoax refers to water by the rarely used formal name "dihydrogen monoxide" and describes it as the main constituent in most poisonous solutions to show how easily the general public can be misled. Using established terms in idiosyncratic ways, thereby demonstrating unfamiliarity with mainstream work in the discipline. Prevalence of pseudoscientific beliefs India The Ministry of AYUSH (expanded form Ayurveda, Yoga, Naturopathy, Unani, Siddha, Sowa-Rigpa and Homoeopathy) in the Government of India is purposed with developing education, research and propagation of indigenous alternative medicine systems in India. As per notification published in the Gazette of India on 13 April 2021, it is known as the Ministry of Ayush and includes the seven traditional systems of healthcare. The ministry has faced significant criticism for funding systems that lack biological plausibility and are either untested or conclusively proven as ineffective. Quality of research has been poor, and drugs have been launched without any rigorous pharmacological studies and meaningful clinical trials on Ayurveda or other alternative healthcare systems. There is no credible efficacy or scientific basis of any of these forms of treatment. A strong consensus prevails among the scientific community that homeopathy is a pseudo-scientific, unethical and implausible line of treatment. Ayurveda is deemed to be pseudoscientific but is occasionally considered a protoscience, or trans-science system instead. Naturopathy is considered to be a form of pseudo-scientific quackery, ineffective and possibly harmful, with a plethora of ethical concerns about the very practice. Much of the research on postural yoga has taken the form of preliminary studies or clinical trials of low methodological quality; there is no conclusive therapeutic effect except in back pain. Unani lacks biological plausibility and is considered to be pseudo-scientific quackery, as well. Vastu shastra is the ancient Hindu system of architecture, which lays down a series of rules for building houses in relation to ambiance. Vastu Shastra is considered as pseudoscience by rationalists like Narendra Nayak of Federation of Indian Rationalist Associations and astronomer Jayant Narlikar, who writes that Vastu does not have any "logical connection" to the environment. Jyotisha is the traditional Hindu system of astrology, also known as Hindu astrology, Indian astrology and more recently Vedic astrology. The scientific consensus is that astrology is a pseudoscience. United States A large percentage of the United States population lacks scientific literacy, not adequately understanding scientific principles and method. In the Journal of College Science Teaching, Art Hobson writes, "Pseudoscientific beliefs are surprisingly widespread in our culture even among public school science teachers and newspaper editors, and are closely related to scientific illiteracy." However, a 10,000-student study in the same journal concluded there was no strong correlation between science knowledge and belief in pseudoscience. In his book The Demon-Haunted World, Carl Sagan discusses the government of China and the Chinese Communist Party's concern about Western pseudoscience developments and certain ancient Chinese practices in China. He sees pseudoscience occurring in the United States as part of a worldwide trend and suggests its causes, dangers, diagnosis and treatment may be universal. During 2006, the U.S. National Science Foundation (NSF) issued an executive summary of a paper on science and engineering which briefly discussed the prevalence of pseudoscience in modern times. It said, "belief in pseudoscience is widespread" and, referencing a Gallup Poll, stated that belief in the 10 commonly believed examples of paranormal phenomena listed in the poll were "pseudoscientific beliefs". The items were "extrasensory perception (ESP), that houses can be haunted, ghosts, telepathy, clairvoyance, astrology, that people can communicate mentally with someone who has died, witches, reincarnation, and channelling". Such beliefs in pseudoscience represent a lack of knowledge of how science works. The scientific community may attempt to communicate information about science out of concern for the public's susceptibility to unproven claims. The NSF stated that pseudoscientific beliefs in the U.S. became more widespread during the 1990s, peaked about 2001, and then decreased slightly since with pseudoscientific beliefs remaining common. According to the NSF report, there is a lack of knowledge of pseudoscientific issues in society and pseudoscientific practices are commonly followed. Surveys indicate about a third of adult Americans consider astrology to be scientific. Racism There have been many connections between writers and researchers of pseudoscience and their anti-semitism, racism and neo-Nazism backgrounds. They often use pseudoscience to reinforce their beliefs. One of the most predominant pseudoscientific writers is Frank Collin, a self-proclaimed Nazi who goes by Frank Joseph in his writings. The majority of his works include the topics of Atlantis, extraterrestrial encounters, and Lemuria as well as other ancient civilizations, often with white supremacist undertones. For example, he posited that European peoples migrated to North America before Columbus, and that all Native American civilizations were initiated by descendants of white people. The Alt-Right using pseudoscience to base their ideologies on is not a new issue. The entire foundation of anti-semitism is based on pseudoscience, or scientific racism. In an article from Newsweek by Sander Gilman, Gilman describes the pseudoscience community's anti-semitic views. "Jews as they appear in this world of pseudoscience are an invented group of ill, stupid or stupidly smart people who use science to their own nefarious ends. Other groups, too, are painted similarly in 'race science', as it used to call itself: African-Americans, the Irish, the Chinese and, well, any and all groups that you want to prove inferior to yourself". Neo-Nazis and white supremacist often try to support their claims with studies that "prove" that their claims are more than just harmful stereotypes. For example Bret Stephens published a column in the New York Times where he claimed that Ashkenazi Jews had the highest IQ among any ethnic group.

Michael Shermer's theory of belief-dependent realism is driven by the belief that the brain is essentially a "belief engine" which scans data perceived by the senses and looks for patterns and meaning. There is also the tendency for the brain to create cognitive biases, as a result of inferences and assumptions made without logic and based on instinct – usually resulting in patterns in cognition. These tendencies of patternicity and agenticity are also driven "by a meta-bias called the bias blind spot, or the tendency to recognize the power of cognitive biases in other people but to be blind to their influence on our own beliefs". Lindeman states that social motives (i.e., "to comprehend self and the world, to have a sense of control over outcomes, to belong, to find the world benevolent and to maintain one's self-esteem") are often "more easily" fulfilled by pseudoscience than by scientific information. Furthermore, pseudoscientific explanations are generally not analyzed rationally, but instead experientially. Operating within a different set of rules compared to rational thinking, experiential thinking regards an explanation as valid if the explanation is "personally functional, satisfying and sufficient", offering a description of the world that may be more personal than can be provided by science and reducing the amount of potential work involved in understanding complex events and outcomes.

"Jews as they appear in this world of pseudoscience are an invented group of ill, stupid or stupidly smart people who use science to their own nefarious ends. Other groups, too, are painted similarly in 'race science', as it used to call itself: African-Americans, the Irish, the Chinese and, well, any and all groups that you want to prove inferior to yourself". Neo-Nazis and white supremacist often try to support their claims with studies that "prove" that their claims are more than just harmful stereotypes. For example Bret Stephens published a column in the New York Times where he claimed that Ashkenazi Jews had the highest IQ among any ethnic group.

The large category of non-science includes all matters outside the natural and social sciences, such as the study of history, metaphysics, religion, art, and the humanities. Dividing the category again, unscientific claims are a subset of the large category of non-scientific claims. This category specifically includes all matters that are directly opposed to good science. Un-science includes both "bad science" (such as an error made in a good-faith attempt at learning something about the natural world) and pseudoscience. Thus pseudoscience is a subset of un-science, and un-science, in turn, is subset of non-science. Science is also distinguishable from revelation, theology, or spirituality in that it offers insight into the physical world obtained by empirical research and testing. The most notable disputes concern the evolution of living organisms, the idea of common descent, the geologic history of the Earth, the formation of the solar system, and the origin of the universe. Systems of belief that derive from divine or inspired knowledge are not considered pseudoscience if they do not claim either to be scientific or to overturn well-established science. Moreover, some specific religious claims, such as the power of intercessory prayer to heal the sick, although they may be based on untestable beliefs, can be tested by the scientific method. Some statements and common beliefs of popular science may not meet the criteria of science. "Pop" science may blur the divide between science and pseudoscience among the general public, and may also involve science fiction. Indeed, pop science is disseminated to, and can also easily emanate from, persons not accountable to scientific methodology and expert peer review. If claims of a given field can be tested experimentally and standards are upheld, it is not pseudoscience, regardless of how odd, astonishing, or counterintuitive those claims are. If claims made are inconsistent with existing experimental results or established theory, but the method is sound, caution should be used, since science consists of testing hypotheses which may turn out to be false. In such a case, the work may be better described as ideas that are "not yet generally accepted". Protoscience is a term sometimes used to describe a hypothesis that has not yet been tested adequately by the scientific method, but which is otherwise consistent with existing science or which, where inconsistent, offers reasonable account of the inconsistency. It may also describe the transition from a body of practical knowledge into a scientific field. Philosophy Karl Popper stated it is insufficient to distinguish science from pseudoscience, or from metaphysics (such as the philosophical question of what existence means), by the criterion of rigorous adherence to the empirical method, which is essentially inductive, based on observation or experimentation. He proposed a method to distinguish between genuine empirical, nonempirical or even pseudoempirical methods. The latter case was exemplified by astrology, which appeals to observation and experimentation. While it had empirical evidence based on observation, on horoscopes and biographies, it crucially failed to use acceptable scientific standards. Popper proposed falsifiability as an important criterion in distinguishing science from pseudoscience. To demonstrate this point, Popper gave two cases of human behavior and typical explanations from Sigmund Freud and Alfred Adler's theories: "that of a man who pushes a child into the water with the intention of drowning it; and that of a man who sacrifices his life in an attempt to save the child." From Freud's perspective, the first man would have suffered from psychological repression, probably originating from an Oedipus complex, whereas the second man had attained sublimation. From Adler's perspective, the first and second man suffered from feelings of inferiority and had to prove himself, which drove him to commit the crime or, in the second case, drove him to rescue the child. Popper was not able to find any counterexamples of human behavior in which the behavior could not be explained in the terms of Adler's or Freud's theory. Popper argued it was that the observation always fitted or confirmed the theory which, rather than being its strength, was actually its weakness. In contrast, Popper gave the example of Einstein's gravitational theory, which predicted "light must be attracted by heavy bodies (such as the Sun), precisely as material bodies were attracted." Following from this, stars closer to the Sun would appear to have moved a small distance away from the Sun, and away from each other. This prediction was particularly striking to Popper because it involved considerable risk. The brightness of the Sun prevented this effect from being observed under normal circumstances, so photographs had to be taken during an eclipse and compared to photographs taken at night. Popper states, "If observation shows that the predicted effect is definitely absent, then the theory is simply refuted." Popper summed up his criterion for the scientific status of a theory as depending on its falsifiability, refutability, or testability. Paul R. Thagard used astrology as a case study to distinguish science from pseudoscience and proposed principles and criteria to delineate them. First, astrology has not progressed in that it has not been updated nor added any explanatory power since Ptolemy. Second, it has ignored outstanding |
diseases can arise in three different ways: acquired, familial, or sporadic. It is often assumed that the diseased form directly interacts with the normal form to make it rearrange its structure. One idea, the "Protein X" hypothesis, is that an as-yet unidentified cellular protein (Protein X) enables the conversion of PrPC to PrPSc by bringing a molecule of each of the two together into a complex. The primary method of infection in animals is through ingestion. It is thought that prions may be deposited in the environment through the remains of dead animals and via urine, saliva, and other body fluids. They may then linger in the soil by binding to clay and other minerals. A University of California research team has provided evidence for the theory that infection can occur from prions in manure. And, since manure is present in many areas surrounding water reservoirs, as well as used on many crop fields, it raises the possibility of widespread transmission. It was reported in January 2011 that researchers had discovered prions spreading through airborne transmission on aerosol particles, in an animal testing experiment focusing on scrapie infection in laboratory mice. Preliminary evidence supporting the notion that prions can be transmitted through use of urine-derived human menopausal gonadotropin, administered for the treatment of infertility, was published in 2011. Prions in plants In 2015, researchers at The University of Texas Health Science Center at Houston found that plants can be a vector for prions. When researchers fed hamsters grass that grew on ground where a deer that died with chronic wasting disease (CWD) was buried, the hamsters became ill with CWD, suggesting that prions can bind to plants, which then take them up into the leaf and stem structure, where they can be eaten by herbivores, thus completing the cycle. It is thus possible that there is a progressively accumulating number of prions in the environment. Sterilization Infectious particles possessing nucleic acid are dependent upon it to direct their continued replication. Prions, however, are infectious by their effect on normal versions of the protein. Sterilizing prions, therefore, requires the denaturation of the protein to a state in which the molecule is no longer able to induce the abnormal folding of normal proteins. In general, prions are quite resistant to proteases, heat, ionizing radiation, and formaldehyde treatments, although their infectivity can be reduced by such treatments. Effective prion decontamination relies upon protein hydrolysis or reduction or destruction of protein tertiary structure. Examples include sodium hypochlorite, sodium hydroxide, and strongly acidic detergents such as LpH. The World Health Organization recommends any of the following three procedures for the sterilization of all heat-resistant surgical instruments to ensure that they are not contaminated with prions: Immerse in 1N sodium hydroxide and place in a gravity-displacement autoclave at 121 °C for 30 minutes; clean; rinse in water; and then perform routine sterilization processes. Immerse in 1N sodium hypochlorite (20,000 parts per million available chlorine) for 1 hour; transfer instruments to water; heat in a gravity-displacement autoclave at 121 °C for 1 hour; clean; and then perform routine sterilization processes. Immerse in 1N sodium hydroxide or sodium hypochlorite (20,000 parts per million available chlorine) for 1 hour; remove and rinse in water, then transfer to an open pan and heat in a gravity-displacement (121 °C) or in a porous-load (134 °C) autoclave for 1 hour; clean; and then perform routine sterilization processes. for 18 minutes in a pressurized steam autoclave has been found to be somewhat effective in deactivating the agent of disease. Ozone sterilization is currently being studied as a potential method for prion denaturation and deactivation. Other approaches being developed include thiourea-urea treatment, guanidinium chloride treatment, and special heat-resistant subtilisin combined with heat and detergent. A method sufficient for sterilizing prions on one material may fail on another. Renaturation of a completely denatured prion to infectious status has not yet been achieved; however, partially denatured prions can be renatured to an infective status under certain artificial conditions. Degradation resistance in nature Overwhelming evidence shows that prions resist degradation and persist in the environment for years, and proteases do not degrade them. Experimental evidence shows that unbound prions degrade over time, while soil-bound prions remain at stable or increasing levels, suggesting that prions likely accumulate in the environment. One 2015 study by US scientists found that repeated drying and wetting may render soil bound prions less infectious, although this was dependent on the soil type they were bound to. Fungi Proteins showing prion-type behavior are also found in some fungi, which has been useful in helping to understand mammalian prions. Fungal prions do not appear to cause disease in their hosts. In yeast, protein refolding to the prion configuration is assisted by chaperone proteins such as Hsp104. All known prions induce the formation of an amyloid fold, in which the protein polymerises into an aggregate consisting of tightly packed beta sheets. Amyloid aggregates are fibrils, growing at their ends, and replicate when breakage causes two growing ends to become four growing ends. The incubation period of prion diseases is determined by the exponential growth rate associated with prion replication, which is a balance between the linear growth and the breakage of aggregates. Fungal proteins exhibiting templated conformational change were discovered in the yeast Saccharomyces cerevisiae by Reed Wickner in the early 1990s. For their mechanistic similarity to mammalian prions, they were termed yeast prions. Subsequent to this, a prion has also been found in the fungus Podospora anserina. These prions behave similarly to PrP, but, in general, are nontoxic to their hosts. Susan Lindquist's group at the Whitehead Institute has argued some of the fungal prions are not associated with any disease state, but may have a useful role; however, researchers at the NIH have also provided arguments suggesting that fungal prions could be considered a diseased state. There is evidence that fungal proteins have evolved specific functions that are beneficial to the microorganism that enhance their ability to adapt to their diverse environments. Research into fungal prions has given strong support to the protein-only concept, since purified protein extracted from cells with a prion state has been demonstrated to convert the normal form of the protein into a misfolded form in vitro, and in the process, preserve the information corresponding to different strains of the prion state. It has also shed some light on prion domains, which are regions in a protein that promote the conversion into a prion. Fungal prions have helped to suggest mechanisms of conversion that may apply to all prions, though fungal prions appear distinct from infectious mammalian prions in the lack of cofactor required for propagation. The characteristic prion domains may vary between species – e.g., characteristic fungal prion domains are not found in mammalian prions. Treatments There are no effective treatments for prion diseases. Clinical trials in humans have not met with success and have been hampered by the rarity of prion diseases. Although some potential treatments have shown promise in the laboratory, none has been effective once the disease has commenced. In other diseases Prion-like domains have been found in a variety of other mammalian proteins. Some of these proteins have been implicated in the ontogeny of age-related neurodegenerative disorders such as amyotrophic lateral sclerosis (ALS), frontotemporal lobar degeneration with ubiquitin-positive inclusions (FTLD-U), Alzheimer's disease, Parkinson's disease, and Huntington's disease. They are also implicated in some forms of systemic amyloidosis including AA amyloidosis that develops in humans and animals with inflammatory and infectious diseases such as tuberculosis, Crohn's disease, rheumatoid arthritis, and HIV/AIDS. AA amyloidosis, like prion disease, may be transmissible. This has given rise to the 'prion paradigm', where otherwise harmless proteins can be converted to a pathogenic form by a small number of misfolded, nucleating proteins. The definition of a prion-like domain arises from the study of fungal prions. In yeast, prionogenic proteins have a portable prion domain that is both necessary and sufficient for self-templating and protein aggregation. This has been shown by attaching the prion domain to a reporter protein, which then aggregates like a known prion. Similarly, removing the prion domain from a fungal prion protein inhibits prionogenesis. This modular view of prion behaviour has led to the hypothesis that similar prion domains are present in animal proteins, in addition to PrP. These fungal prion domains have several characteristic sequence features. They are typically enriched in asparagine, glutamine, tyrosine and glycine residues, with an asparagine bias being particularly conducive to the aggregative property of prions. Historically, prionogenesis has been seen as independent of sequence and only dependent on relative residue content. However, this has been shown to be false, with the spacing of prolines and charged residues having been shown to be critical in amyloid formation. Bioinformatic | the incubation period for prion diseases is relatively long (5 to 20 years), once symptoms appear the disease progresses rapidly, leading to brain damage and death. Neurodegenerative symptoms can include convulsions, dementia, ataxia (balance and coordination dysfunction), and behavioural or personality changes. Many different mammalian species can be affected by prion diseases, as the prion protein (PrP) is very similar in all mammals. Due to small differences in PrP between different species it is unusual for a prion disease to transmit from one species to another. The human prion disease variant Creutzfeldt–Jakob disease, however, is thought to be caused by a prion that typically infects cattle, causing bovine spongiform encephalopathy and is transmitted through infected meat. All known prion diseases are untreatable and fatal. However, a vaccine developed in mice may provide insight into providing a vaccine to resist prion infections in humans. Additionally, in 2006 scientists announced that they had genetically engineered cattle lacking a necessary gene for prion production – thus theoretically making them immune to BSE, building on research indicating that mice lacking normally occurring prion protein are resistant to infection by scrapie prion protein. In 2013, a study revealed that 1 in 2,000 people in the United Kingdom might harbour the infectious prion protein that causes vCJD. Until 2015 all known mammalian prion diseases were considered to be caused by the prion protein, PrP; in 2015 multiple system atrophy was found to be transmissible and was hypothesized to be caused by a new prion, the misfolded form of a protein called alpha-synuclein. The endogenous, properly folded form of the prion protein is denoted PrPC (for Common or Cellular), whereas the disease-linked, misfolded form is denoted PrPSc (for Scrapie), after one of the diseases first linked to prions and neurodegeneration. The precise structure of the prion is not known, though they can be formed spontaneously by combining PrPC, homopolymeric polyadenylic acid, and lipids in a protein misfolding cyclic amplification (PMCA) reaction even in the absence of pre-existing infectious prions. This result is further evidence that prion replication does not require genetic information. Transmission It has been recognized that prion diseases can arise in three different ways: acquired, familial, or sporadic. It is often assumed that the diseased form directly interacts with the normal form to make it rearrange its structure. One idea, the "Protein X" hypothesis, is that an as-yet unidentified cellular protein (Protein X) enables the conversion of PrPC to PrPSc by bringing a molecule of each of the two together into a complex.

synthesised in the laboratory in 1940, when neptunium was made. The row was completed with the synthesis of tennessine in 2010 (the last element oganesson had already been made in 2002), and the last elements in this seventh row were validated and given names in 2016. This completes the modern periodic table, with all seven rows completely filled to capacity. The following table shows the electron configuration of a neutral gas-phase atom of each element. Different configurations can be favoured in different chemical environments. The main-group elements have entirely regular electron configurations; the transition and inner transition elements show a number of irregularities due to the aforementioned competition between subshells close in energy level. For the last ten elements (109–118), experimental data is lacking and therefore calculated configurations have been shown instead. Completely filled subshells have been greyed out. Presentation forms For reasons of space, the periodic table is commonly presented with the f-block elements cut out and placed as a footnote below the main body of the table, as below. Both forms represent the same periodic table. The form with the f-block included in the main body is sometimes called the 32-column or long form; the form with the f-block cut out is sometimes called the 18-column or medium-long form. The 32-column form has the advantage of showing all elements in their correct sequence, but it has the disadvantage of requiring more space. All periodic tables show the elements' symbols; many also provide supplementary information about the elements, either via colour-coding or as data in the cells. The above table shows the names and atomic numbers of the elements, and also their blocks, natural occurrences and standard atomic weights. For the short-lived elements without standard atomic weights, the mass number of the most stable known isotope is used instead. Other tables may include properties such as state of matter, melting and boiling points, densities, as well as provide different classifications of the elements. Under an international naming convention, the groups are numbered numerically from 1 to 18 from the leftmost column (the alkali metals) to the rightmost column (the noble gases). The f-block groups are ignored in this numbering. Previously, groups were known by Roman numerals. In America, the Roman numerals were followed by either an "A" if the group was in the s- or p-block, or a "B" if the group was in the d-block. The Roman numerals used correspond to the last digit of today's naming convention (e.g. the group 4 elements were group IVB, and the group 14 elements were group IVA). In Europe, the lettering was similar, except that "A" was used if the group was before group 10, and "B" was used for groups including and after group 10. In addition, groups 8, 9 and 10 used to be treated as one triple-sized group, known collectively in both notations as group VIII. In 1988, the new IUPAC naming system was put into use, and the old group names were deprecated. Periodic trends As chemical reactions involve the valence electrons, elements with similar outer electron configurations may be expected to react similarly and form compounds with similar proportions of elements in them. Such elements are placed in the same group, and thus there tend to be clear similarities and trends in chemical behaviour as one proceeds down a group. As analogous configurations return at regular intervals, the properties of the elements thus exhibit periodic recurrences, hence the name of the periodic table and the periodic law. These periodic recurrences were noticed well before the underlying theory that explains them was developed. For example, the valence of an element can be defined either as the number of hydrogen atoms that can combine with it to form a simple binary hydride, or as twice the number of oxygen atoms that can combine with it to form a simple binary oxide (that is, not a peroxide or a superoxide). The valences of the main-group elements are directly related to the group number: the hydrides in the main groups 1–2 and 13–17 follow the formulae MH, MH2, MH3, MH4, MH3, MH2, and finally MH. The highest oxides instead increase in valence, following the formulae M2O, MO, M2O3, MO2, M2O5, MO3, M2O7. The electron configuration suggests a ready explanation from the number of electrons available for bonding, although a full explanation requires considering the energy that would be released in forming compounds with different valences rather than simply considering electron configurations alone. Today the notion of valence has been extended by that of the oxidation state, which is the formal charge left on an element when all other elements in a compound have been removed as their ions. As elements in the same group share the same valence configurations, they usually exhibit similar chemical behaviour. For example, the alkali metals in the first group all have one valence electron, and form a very homogeneous class of elements: they are all soft and reactive metals. However, there are many factors involved, and groups can often be rather hetereogeneous. For instance, the stable elements of group 14 comprise a nonmetal (carbon), two semiconductors (silicon and germanium), and two metals (tin and lead). They are nonetheless united by having four valence electrons. Atomic radius Atomic radii (the size of atoms) generally decrease going left to right along the main-group elements, because the nuclear charge increases but the outer electrons are still in the same shell. However, going down a column, the radii generally increase, because the outermost electrons are in higher shells that are thus further away from the nucleus. In the transition elements, an inner shell is filling, but the size of the atom is still determined by the outer electrons. The increasing nuclear charge across the series and the increased number of inner electrons for shielding somewhat compensate each other, so the decrease in radius is smaller. The 4p and 5d atoms, coming immediately after new types of transition series are first introduced, are smaller than would have been expected. Ionisation energy The first ionisation energy of an atom is the energy required to remove an electron from it. This varies with the atomic radius: ionisation energy increases left to right and down to up, because electrons that are closer to the nucleus are held more tightly and are more difficult to remove. Ionisation energy thus is minimised at the first element of each period – hydrogen and the alkali metals – and then generally rises until it reaches the noble gas at the right edge of the period. There are some exceptions to this trend, such as oxygen, where the electron being removed is paired and thus interelectronic repulsion makes it easier to remove than expected. In the transition series, the outer electrons are preferentially lost even though the inner orbitals are filling. For example, in the 3d series, the 4s electrons are lost first even though the 3d orbitals are being filled. The shielding effect of adding an extra 3d electron approximately compensates the rise in nuclear charge, and therefore the ionisation energies stay mostly constant, though there is a small increase especially at the end of each transition series. As metal atoms tend to lose electrons in chemical reactions, ionisation energy is generally correlated with chemical reactivity, although there are other factors involved as well. Electron affinity The opposite property to ionisation energy is the electron affinity, which is the energy released when adding an electron to the atom. A passing electron will be more readily attracted to an atom if it feels the pull of the nucleus more strongly, and especially if there is an available partially filled outer orbital that can accommodate it. Therefore, electron affinity tends to increase down to up and left to right. The exception is the last column, the noble gases, which have a full shell and have no room for another electron. This gives the halogens in the next-to-last column the highest electron affinities. Some atoms, like the noble gases, have no electron affinity: they cannot form stable gas-phase anions. The noble gases, having high ionisation energies and no electron affinity, have little inclination towards gaining or losing electrons and are generally unreactive. Some exceptions to the trends occur: oxygen and fluorine have lower electron affinities than their heavier homologues sulfur and chlorine, because they are small atoms and hence the newly added electron would experience significant repulsion from the already present ones. For the nonmetallic elements, electron affinity likewise somewhat correlates with reactivity, but not perfectly since other factors are involved. For example, fluorine has a lower electron affinity than chlorine, but is more reactive. Electronegativity Another important property of elements is their electronegativity. Atoms can form covalent bonds to each other by sharing electrons in pairs, creating an overlap of valence orbitals. The degree to which each atom attracts the shared electron pair depends on the atom's electronegativity – the tendency of an atom towards gaining or losing electrons. The more electronegative atom will tend to attract the electron pair more, and the less electronegative (or more electropositive) one will attract it less. In extreme cases, the electron can be thought of as having been passed completely from the more electropositive atom to the more electronegative one, though this is a simplification. The bond then binds two ions, one positive (having given up the electron) and one negative (having accepted it), and is termed an ionic bond. Electronegativity depends on how strongly the nucleus can attract an electron pair, and so it exhibits a similar variation to the other properties already discussed: electronegativity tends to fall going up to down, and rise going left to right. The alkali and alkaline earth metals are among the most electropositive elements, while the chalcogens, halogens, and noble gases are among the most electronegative ones. Electronegativity is generally measured on the Pauling scale, on which the most electronegative reactive atom (fluorine) is given electronegativity 4.0, and the least electronegative atom (caesium) is given electronegativity 0.79. (Theoretically neon would be more electronegative than fluorine, but the Pauling scale cannot measure its electronegativity because it does not form covalent bonds.) Electronegativity of an element also somewhat depends on the identity and number of the atoms it is bonded to, as well as how many electrons it has already lost: an atom becomes more electronegative when it has lost more electrons. These effects leave the general trend intact. Metallicity A simple substance is a substance formed from atoms of one chemical element. The simple substances of the more electronegative atoms tend to share electrons (form covalent bonds) which each other. They form either small molecules (like hydrogen or oxygen, whose atoms bond in pairs) or giant structures stretching indefinitely (like carbon or silicon). The noble gases simply stay as single atoms, as they already have a full shell. Substances composed of discrete molecules or single atoms are held together by weaker attractive forces between the molecules, such as the London dispersion force: as electrons move within the molecules, they create momentary imbalances of electrical charge, which induce similar imbalances on nearby molecules and create synchronised movements of electrons across many neighbouring molecules. The more electropositive atoms, however, tend to instead lose electrons, creating a "sea" of electrons engulfing cations. The outer orbitals of one atom overlap to share electrons with all its neighbours, creating a giant structure of molecular orbitals extending all over the structure. This negatively charged "sea" pulls on all the ions and keeps them together in a metallic bond. Elements forming such bonds are often called metals; those which do not are often called nonmetals. Some elements can form multiple simple substances with different structures: these are called allotropes. For example, diamond and graphite are two allotropes of carbon. Due to the aforementioned trends, metals are generally found towards the left side of the periodic table, and nonmetals towards the right side. Metallicity tends to be correlated with electropositivity and the willingness to lose electrons, which increases right to left and up to down; therefore, the dividing line between metals and nonmetals is roughly diagonal from top left to bottom right. Most elements are metals, because the transition series appear to the left of this diagonal. Elements near the borderline are difficult to classify: they tend to have properties that are intermediate between those of metals and nonmetals, and may have some properties characteristic of both. They are often termed semi-metals or metalloids. For example, arsenic has multiple allotropes, but only one conducts electricity like a metal. The following table considers the most stable allotropes at standard conditions. The elements coloured yellow form simple substances that are well-characterised by metallic bonding. Elements coloured light blue form giant covalent structures, whereas those coloured dark blue form small covalently bonded molecules that are held together by weaker van der Waals forces. The noble gases are coloured in violet: their molecules are single atoms and no covalent bonding occurs. Greyed-out cells are for elements which have not been prepared in sufficient quantities for their most stable allotropes to have been characterised in this way. It is theoretically expected that most of these should be metals, and there is some indirect experimental evidence that this is true for fermium and mendelevium, but some question remains for copernicium and oganesson where theoretical models do not agree. Generally, metals are shiny and dense. They usually have high melting and boiling points due to the strength of the metallic bond, and are malleable and ductile (easily stretched and shaped) because the atoms can move relative to each other without breaking the metallic bond. They conduct electricity because their electrons are free to move in all three dimensions. Similarly, they conduct heat, which is transferred by the electrons as extra kinetic energy: they move faster. These properties persist in the liquid state, as although the crystal structure is destroyed on melting, the atoms still touch and the metallic bond persists, though it is weakened. Metals tend to be reactive towards nonmetals. Nonmetals exhibit different properties. Those forming giant covalent crystals exhibit high melting and boiling points, as it takes a lot of energy to overcome the strong covalent bonds. Those forming discrete molecules are held together mostly by dispersion forces, which are more easily overcame; thus they tend to have lower melting and boiling points, and many are liquids or gases at room temperature. Nonmetals are often dull-looking. They tend to be reactive towards metals, except for the noble gases, which are inert towards most substances. They are brittle when solid as their atoms are held tightly in place. They are less dense and conduct electricity poorly, because there are no mobile electrons; the orbitals that overlap and would allow the electrons to move freely are too high in energy to reach. However, especially near the borderline, this energy gap is small and electrons can readily cross it when thermally excited. Hence, many elements near the borderline are semiconductors, such as silicon, germanium, selenium in its gray allotrope, and tellurium. As such, it is common to designate a class of metalloids straddling the boundary between metals and nonmetals, as elements in that region are intermediate in both physical and chemical properties. However, no consensus exists in the literature for precisely which elements should be so designated. When such a category is used, boron, silicon, germanium, arsenic, antimony, and tellurium are usually included; but most sources include other elements as well, without agreement on which extra elements should be added, and some others subtract from this list instead. For example, the periodic table used by the American Chemical Society includes polonium as a metalloid, but that used by the Royal Society of Chemistry does not, and that included in the Encyclopædia Britannica does not refer to metalloids or semi-metals at all. Further manifestations of periodicity There are some other relationships throughout the periodic table between elements that are not in the same group, such as the diagonal relationships between elements that are diagonally adjacent (e.g. lithium and magnesium). Some similarities can also be found between the main groups and the transition metal groups, or between the early actinides and early transition metals, when the elements have the same number of valence electrons. Thus uranium somewhat resembles chromium and tungsten in group 6, as all three have six valence electrons. The first row of every block tends to show rather distinct properties from the other rows, because the first orbital of each type (1s, 2p, 3d, 4f, 5g, etc.) is significantly smaller than would be expected. The degree of the anomaly is highest for the s-block, is moderate for the p-block, and is less pronounced for the d- and f-blocks. There is also an even-odd difference between the periods (except in the s-block) that is sometimes known as secondary periodicity: elements in even periods have smaller atomic radii and prefer to lose fewer electrons, while elements in odd periods (except the first) differ in the opposite direction. Thus, many properties in the p-block show a zigzag rather than a smooth trend along the group. For example, phosphorus and antimony in odd periods of group 15 readily reach the +5 oxidation state, whereas nitrogen, arsenic, and bismuth in even periods prefer to stay at +3. When atomic nuclei become highly charged, special relativity becomes needed to gauge the effect of the nucleus on the electron cloud. These relativistic effects result in heavy elements increasingly having differing properties compared to their lighter homologues in the periodic table. For example, relativistic effects explain why gold is golden and mercury is a liquid. These effects are expected to become very strong in the late seventh period, potentially leading to a collapse of periodicity. Electron configurations and chemical properties are only clearly known till element 108 (hassium), so the chemical characterisation of the heaviest elements remains a topic of current research. Many other physical properties of the elements exhibit periodic variation in accordance with the periodic law, such as melting points, boiling points, heats of fusion, heats of vaporisation, atomisation energy, and so on. Similar periodic variations appear for the compounds of the elements, which can be observed by comparing hydrides, oxides, sulfides, halides, and so on. Chemical properties are more difficult to describe quantitatively, but likewise exhibit their own periodicities. Examples include how oxidation states tend to vary in steps of 2 in the main-group elements, but in steps of 1 for the transition elements; the variation in the acidic and basic properties of the elements and their compounds; the stabilities of compounds; and methods of isolating the elements. Periodicity is and has been used very widely to predict the properties of unknown new elements and new compounds, and is central to modern chemistry. Classification of elements Many terms have been used in the literature to describe sets of elements that behave similarly. The group names alkali metal, alkaline earth metal, pnictogen, chalcogen, halogen, and noble gas are acknowledged by IUPAC; the other groups can be referred to by their number, or by their first element (e.g., group 6 is the chromium group). Some divide the p-block elements from groups 13 to 16 by metallicity, although there is neither a IUPAC definition nor a precise consensus on exactly which elements should be considered metals, nonmetals, or semi-metals (sometimes called metalloids). Neither is there a consensus on what the metals succeeding the transition metals ought to be called, with post-transition metal and poor metal being among the possibilities having been used. Some advanced monographs exclude the elements of group 12 from the transition metals on the grounds of their sometimes quite different chemical properties, but this is not a universal practice. The lanthanides are considered to be the elements La–Lu, which are all very similar to each other: historically they included only Ce–Lu, but lanthanum became included by common usage. The rare earth elements (or rare earth metals) add scandium and yttrium to the lanthanides. Analogously, the actinides are considered to be the elements Ac–Lr (historically Th–Lr), although variation of properties in this set is much greater than within the lanthanides. IUPAC recommends the names lanthanoids and actinoids to avoid ambiguity, as the -ide suffix typically denotes a negative ion; however lanthanides and actinides remain common. Many more categorisations exist and are used according to certain disciplines. In astrophysics, a metal is defined as any element with atomic number greater than 2, i.e. anything except hydrogen and helium. Physics has its own definitions for metals and semi-metals that do not coincide with the chemical idea of metallicity. A few terms are widely used, but without any very formal definition, such as "heavy metal", which has been given such a wide range of definitions that it has been criticised as "effectively meaningless". The scope of terms varies significantly between authors. For example, according to IUPAC, the noble gases extend to include the whole group, including the very radioactive superheavy element oganesson. However, among those who specialise in the superheavy elements, this is not often done: in this case "noble gas" is typically taken to imply the unreactive behaviour of the lighter elements of the group. Since calculations generally predict that oganesson should not be particularly inert due to relativistic effects, its status as a noble gas is often questioned in this context. Furthermore, national variations are sometimes encountered: in Japan, alkaline earth metals often do not include beryllium and magnesium as their behaviour is different from the heavier group 2 metals. History In 1817, German physicist Johann Wolfgang Döbereiner began to formulate one of the earliest attempts to classify the elements. In 1829, he found that he could form some of the elements into groups of three, with the members of each group having related properties. He termed these groups triads. Chlorine, bromine, and iodine formed a triad; as did calcium, strontium, and barium; lithium, sodium, and potassium; and sulfur, selenium, and tellurium. Today, all these triads form part of modern-day groups. Various chemists continued his work and were | how oxidation states tend to vary in steps of 2 in the main-group elements, but in steps of 1 for the transition elements; the variation in the acidic and basic properties of the elements and their compounds; the stabilities of compounds; and methods of isolating the elements.

Chlorine, bromine, and iodine formed a triad; as did calcium, strontium, and barium; lithium, sodium, and potassium; and sulfur, selenium, and tellurium. Today, all these triads form part of modern-day groups. Various chemists continued his work and were able to identify more and more relationships between small groups of elements. However, they could not build one scheme that encompassed them all. German chemist Lothar Meyer noted the sequences of similar chemical and physical properties repeated at periodic intervals. According to him, if the atomic weights were plotted as ordinates (i.e. vertically) and the atomic volumes as abscissas (i.e. horizontally)—the curve obtained a series of maximums and minimums—the most electropositive elements would appear at the peaks of the curve in the order of their atomic weights. In 1864, a book of his was published; it contained an early version of the periodic table containing 28 elements, and classified elements into six families by their valence—for the first time, elements had been grouped according to their valence. Works on organizing the elements by atomic weight had until then been stymied by inaccurate measurements of the atomic weights. In 1868, he revised his table, but this revision was published as a draft only after his death. The definitive breakthrough came from the Russian chemist Dmitri Mendeleev. Although other chemists (including Meyer) had found some other versions of the periodic system at about the same time, Mendeleev was the most dedicated to developing and defending his system, and it was his system that most impacted the scientific community. On 17 February 1869 (1 March 1869 in the Gregorian calendar), Mendeleev began arranging the elements and comparing them by their atomic weights. He began with a few elements, and over the course of the day his system grew till it encompassed most of the known elements. After finding a consistent arrangement, his printed table appeared in May 1869 in the journal of the Russian Chemical Society. In some cases, there appeared to be an element missing from the system, and he boldly predicted that that meant that the element had yet to be discovered. In 1871, Mendeleev published a long article, including an updated form of his table, that made his predictions for unknown elements explicit. Mendeleev predicted the properties of three of these unknown elements in detail: as they would be missing heavier homologues of boron, aluminium, and silicon, he named them eka-boron, eka-aluminium, and eka-silicon ("eka" being Sanskrit for "one"). In 1875, the French chemist Paul-Émile Lecoq de Boisbaudran, working without knowledge of Mendeleev's prediction, discovered a new element in a sample of the mineral sphalerite, and named it gallium. He isolated the element and began determining its properties. Mendeleev, reading de Boisbaudran's publication, sent a letter claiming that gallium was his predicted eka-aluminium. Although Lecoq de Boisbaudran was initially sceptical, and suspected that Mendeleev was trying to take credit for his discovery, he later admitted that Mendeleev was correct. In 1879, the Swedish chemist Lars Fredrik Nilson discovered a new element, which he named scandium: it turned out to be eka-boron. Eka-silicon was found in 1886 by German chemist Clemens Winkler, who named it germanium. The properties of gallium, scandium, and germanium matched what Mendeleev had predicted. In 1889, Mendeleev noted at the Faraday Lecture to the Royal Institution in London that he had not expected to live long enough "to mention their discovery to the Chemical Society of Great Britain as a confirmation of the exactitude and generality of the periodic law". Even the discovery of the noble gases at the close of the 19th century, which Mendeleev had not predicted, fitted neatly into his scheme as an eighth main group. However, Mendeleev had some trouble fitting the known lanthanides into his scheme, as they did not exhibit the periodic change in valencies that the other elements did. After much investigation, the Czech chemist Bohuslav Brauner suggested in 1902 that the lanthanides could all be placed together in one group on the periodic table. He named this the "asteroid hypothesis" as an astronomical analogy: just as there is an asteroid belt instead of a single planet between Mars and Jupiter, so the place below yttrium was occupied by all the lanthanides instead of just one element. After the internal structure of the atom was probed, amateur Dutch physicist Antonius van den Broek proposed in 1913 that the nuclear charge determined the placement of elements in the periodic table. The New Zealand physicist Ernest Rutherford coined the word "atomic number" for this nuclear charge. In van der Broek's published article he illustrated the first electronic periodic table showing the elements arranged according to the number of their electrons. Rutherford confirmed in his 1914 paper that Bohr had accepted the view of van der Broek. The same year, English physicist Henry Moseley using X-ray spectroscopy confirmed van den Broek's proposal experimentally. Moseley determined the value of the nuclear charge of each element from aluminium to gold and showed that Mendeleev's ordering actually places the elements in sequential order by nuclear charge. Nuclear charge is identical to proton count and determines the value of the atomic number (Z) of each element. Using atomic number gives a definitive, integer-based sequence for the elements. Moseley's research immediately resolved discrepancies between atomic weight and chemical properties; these were cases such as tellurium and iodine, where atomic number increases but atomic weight decreases. Although Moseley was soon killed in World War I, the Swedish physicist Manne Siegbahn continued his work up to uranium, and established that it was the element with the highest atomic number then known (92). Based on Moseley and Siegbahn's research, it was also known which atomic numbers corresponded to missing elements yet to be found. The Danish physicist Niels Bohr applied Max Planck's idea of quantisation to the atom. He concluded that the energy levels of electrons were quantised: only a discrete set of stable energy states were allowed. Bohr then attempted to understand periodicity through electron configurations, surmising in 1913 that the inner electrons should be responsible for the chemical properties of the element. In 1913, he produced the first electronic periodic table based on a quantum atom. Bohr called his electron shells "rings" in 1913: atomic orbitals within shells did not exist at the time of his planetary model. Bohr explains in Part 3 of his famous 1913 paper that the maximum electrons in a shell is eight, writing, "We see, further, that a ring of n electrons cannot rotate in a single ring round a nucleus of charge ne unless n < 8." For smaller atoms, the electron shells would be filled as follows: "rings of electrons will only join together if they contain equal numbers of electrons; and that accordingly the numbers of electrons on inner rings will only be 2, 4, 8." However, in larger atoms the innermost shell would contain eight electrons: "on the other hand, the periodic system of the elements strongly suggests that already in neon N = 10 an inner ring of eight electrons will occur." His proposed electron configurations for the light atoms (shown to the right) do not always accord with those now known. The first one to systematically expand and correct the chemical potentials of Bohr's atomic theory was Walther Kossel in 1914 and in 1916. Kossel explained that in the periodic table new elements would be created as electrons were added to the outer shell. In Kossel's paper, he writes: "This leads to the conclusion that the electrons, which are added further, should be put into concentric rings or shells, on each of which ... only a certain number of electrons—namely, eight in our case—should be arranged. As soon as one ring or shell is completed, a new one has to be started for the next element; the number of electrons, which are most easily accessible, and lie at the outermost periphery, increases again from element to element and, therefore, in the formation of each new shell the chemical periodicity is repeated." In a 1919 paper, Irving Langmuir postulated the existence of "cells" which we now call orbitals, which could each only contain two electrons each, and these were arranged in "equidistant layers" which we now call shells. He made an exception for the first shell to only contain two electrons. The chemist Charles Rugeley Bury suggested in 1921 that eight and eighteen electrons in a shell form stable configurations. Bury proposed that the electron configurations in transitional elements depended upon the valence electrons in their outer shell. He introduced the word transition to describe the elements now known as transition metals or transition elements. The quantum theory clarified the transition metals and lanthanides as forming their own separate groups, transitional between the main groups, although some chemists had already proposed tables showing them this way before then: the English chemist Henry Bassett did so in 1892, the Danish chemist Julius Thomsen in 1895, and the Swiss chemist Alfred Werner in 1905. Bohr used Thomsen's form in his 1922 Nobel Lecture; Werner's form is very similar to the modern 32-column form. Prompted by Bohr, Wolfgang Pauli took up the problem of electron configurations in 1923. Pauli extended Bohr's scheme to use four quantum numbers, and formulated his exclusion principle which stated that no two electrons could have the same four quantum numbers. This explained the lengths of the periods in the periodic table (2, 8, 18, and 32), which corresponded to the number of electrons that each shell could occupy. In 1925, Friedrich Hund arrived at configurations close to the modern ones. The Aufbau principle that describes the electron configurations of the elements was first empirically observed by Erwin Madelung in 1926 and published in 1936. By then, the pool of missing elements from hydrogen to uranium had shrunk to four: elements 43, 61, 85, and 87 remained missing. Element 43 eventually became the first element to be synthesised artificially via nuclear reactions rather than discovered in nature. It was discovered in 1937 by Italian chemists Emilio Segrè and Carlo Perrier, who named their discovery technetium, after the Greek word for "artificial". Elements 61 (promethium) and 85 (astatine) were likewise produced artificially; element 87 (francium) became the last element to be discovered in nature, by French chemist Marguerite Perey. The elements beyond uranium were likewise discovered artificially, starting with Edwin McMillan and Philip Abelson's 1940 discovery of neptunium. Glenn T. Seaborg and his team continued discovering transuranium elements, starting with plutonium, and discovered that contrary to previous thinking, the elements from actinium onwards were f-block congeners of the lanthanides rather than d-block transition metals. Bassett (1892), Werner (1905), and the French engineer Charles Janet (1928) had previously suggested this, but their ideas did not then receive general acceptance. Seaborg thus called them the actinides. A significant controversy arose with elements 102 through 106 in the 1960s and 1970s, as competition arose between a team of American scientists at the Lawrence Berkeley National Laboratory (LBNL) and a team of Soviet scientists at the Joint Institute for Nuclear Research (JINR). Each team claimed discovery, and in some cases each proposed their own name for the element, creating an element naming controversy that lasted decades. IUPAC at first adopted a hands-off approach, preferring to wait and see if a consensus would be forthcoming. Unfortunately, it was also the height of the Cold War, and it became clear after some time that this would not happen. As such, IUPAC and the International Union of Pure and Applied Physics (IUPAP) created a Transfermium Working Group (TWG, fermium being element 100) in 1985 to set out criteria for discovery. After some further controversy, these elements received their final names in 1997. The TWG's criteria were used to arbitrate later element discovery claims from research institutes in Germany, Russia, and Japan. Currently, consideration of discovery claims is performed by a IUPAC/IUPAP Joint Working Party. After priority was assigned, the elements were officially added to the periodic table, and the discoverers were invited to propose their names. By 2016, this had occurred for all elements up to 118, therefore completing the periodic table's first seven rows. In celebration of the periodic table's 150th anniversary, the United Nations declared the year 2019 as the International Year of the Periodic Table, celebrating "one of the most significant achievements in science". Today, the periodic table is among the most recognisable icons of chemistry. IUPAC is involved today with many processes relating to the periodic table: the recognition and naming of new elements, recommending group numbers and collective names, determining which elements belong to group 3, and the updating of atomic weights. Current questions Although the modern periodic table is standard today, some variation can be found in period 1 and group 3. Discussion is ongoing about the placements of the relevant elements. The controversy has to do with conflicting understandings of whether chemical or electronic properties should primarily decide periodic table placement, and conflicting views of how the evidence should be used. A similar potential problem has been raised by theoretical investigations of the superheavy elements, whose chemistries may not fit their present position on the periodic table. Period 1 Usually, hydrogen is placed in group 1, and helium in group 18: this is the placement found on the IUPAC periodic table. Some variation can be found on both these matters. Like the group 1 metals, hydrogen has one electron in its outermost shell and typically loses its only electron in chemical reactions. It has some metal-like chemical properties, being able to displace some metals from their salts. But hydrogen forms a diatomic nonmetallic gas at standard conditions, unlike the alkali metals which are reactive solid metals. This and hydrogen's formation of hydrides, in which it gains an electron, brings it close to the properties of the halogens which do the same. Moreover, the lightest two halogens (fluorine and chlorine) are gaseous like hydrogen at standard conditions. Hydrogen thus has properties corresponding to both those of the alkali metals and the halogens, but matches neither group perfectly, and is thus difficult to place by its chemistry. Therefore, while the electronic placement of hydrogen in group 1 predominates, some rarer arrangements show either hydrogen in group 17, duplicate hydrogen in both groups 1 and 17, or float it separately from all groups. Helium is an unreactive noble gas at standard conditions, and has a full outer shell: these properties are like the noble gases in group 18, but not at all like the reactive alkaline earth metals of group 2. Therefore, helium is nearly universally placed in group 18 which its properties best match. However, helium only has two outer electrons in its outer shell, whereas the other noble gases have eight; and it is an s-block element, whereas all other noble gases are p-block elements. Also, solid helium crystallises in a hexagonal close-packed structure, which matches beryllium and magnesium in group 2, but not the other noble gases in group 18. In these ways helium better matches the alkaline earth metals. Therefore, tables with both hydrogen and helium floating outside all groups may rarely be encountered. A few chemists have advocated that the electronic placement in group 2 be adopted for helium. Arguments for this often rest on the first-row anomaly trend, as helium as the first s2 element before the alkaline earth metals stands out as anomalous in a way that helium as the first noble gas does not. Group 3 Published periodic tables show variation regarding the heavier members of group 3, which begins with scandium and yttrium. They are most commonly lanthanum and actinium, but there are many physical and chemical arguments that they should instead be lutetium and lawrencium. A compromise can also sometimes be found, in which the spaces below yttrium are left blank. This leaves it ambiguous if the group only contains scandium and yttrium, or if it also extends to include all thirty lanthanides and actinides. Based on the electron configurations that were known at the time, lanthanum was initially placed as the first of the 5d elements as it added a d-electron to the preceding element, barium. This made it the third member of group 3, with cerium to lutetium then following as the f-block, which then split the d-block in two. But in 1937, it was found that the 4f subshell completed filling at ytterbium rather than at lutetium as had previously been thought. As such, in 1948 the Soviet physicists Lev Landau and Evgeny Lifshitz pointed out in their Course of Theoretical Physics that the new configurations suggested that the first 5d element was lutetium and not lanthanum. This avoids the d-block split by letting the f-block precede the d-block in accordance with the Aufbau principle. Such a placement had previously been adopted by Werner in 1905 (though lutetium had not yet been discovered) and by Janet in 1928. Several physicists and chemists in the following decades supported this reassignment based on other physical and chemical properties of the elements involved, although this evidence has in turn been criticised as having been selectively chosen. Most authors did not make the change. In 1988, a IUPAC report was published that touched on the matter. While it wrote that electron configurations were in favour of the new assignment of group 3 with lutetium and lawrencium, it instead decided on a compromise where the lower spots in group 3 were instead left blank, because the traditional form with lanthanum and actinium remained popular. This is similar to Brauner's 1902 asteroid hypothesis; it makes the f-block appear with 15 elements despite quantum mechanics dictating that it should have 14, and leaves it unclear if group 3 contains only scandium and yttrium, or if it contains all lanthanides and actinides in addition. The IUPAC compromise did not stop the debate. Most sources focusing on the question supported the reassignment, but some authors argued instead in favour of the traditional form with lanthanum as the first 5d element, sometimes giving rise to furious debate. A minority of textbooks accepted the reassignment, but most either showed the older form or the IUPAC compromise. In 2015 IUPAC began a project to decide whether lanthanum or lutetium should go in group 3, chaired by Eric Scerri, a chemist and philosopher of science of Maltese origin. It considered the question to be "of considerable importance" for chemists, physicists, and students, noting that the variation in published periodic tables on this point typically puzzled students and instructors. A provisional report appeared from it in 2021, which was in favour of lutetium as the first 5d element. The reasons given were to display all elements in order of increasing atomic number, avoid the d-block split, and to have the blocks follow the widths quantum mechanics demands of them (2, 6, 10, and 14). The project ended that year. Currently, IUPAC's website on the periodic table still shows the 1988 compromise, but mentions the group 3 problem and project to resolve it, and writes "Stay tune[d]". Superheavy elements Although all elements up to oganesson (element 118) have been discovered, the chemistry of the elements beyond hassium (element 108) is not well-understood. Of these, only copernicium (element 112), nihonium (element 113), and flerovium (element 114) have been experimentally investigated; these investigations so far have not produced conclusive results. Some of the elements past hassium may behave differently from what would be predicted by extrapolation, due to relativistic effects. For example, extrapolation would suggest that copernicium and flerovium behave as metals, like their respective lighter congeners mercury and lead. However, they have been predicted to possibly exhibit some noble-gas-like properties, even though neither is placed in group 18 with the other noble gases. The current experimental evidence still leaves open the question of whether or not this is the case. At the same time, oganesson (element 118) is expected to be a solid semiconductor at standard conditions, similar to silicon in group 14, despite being in group 18. Tennessine (element 117), at the bottom of the halogen group, is expected to be a rather volatile metal with similarities to gallium in group 13; while nihonium, which is actually in group 13, should have similarities to the halogen astatine. Some scientists have argued that should these superheavy elements truly have different properties than their position on the periodic table suggests, the periodic table should be altered to place them with more chemically similar elements. On the other hand, others have argued that the periodic table should reflect atomic structure rather than chemical properties, and oppose such a change. Future extension beyond the seventh period The most recently named elements – nihonium (113), moscovium (115), tennessine (117), and oganesson (118) – completed the seventh row of the periodic table. Future elements would have to begin an eighth row. These elements may be referred to either by their atomic numbers (e.g. "element 119"), or by the IUPAC systematic element names which directly relate to the atomic numbers. All attempts to synthesise such elements have failed so far. An attempt to make element 119 has been ongoing since 2018 at the Riken research institute in Japan. The Joint Institute for Nuclear Research in Russia also plans to make its own attempts at synthesising the first few period 8 elements. Currently, discussion continues if this future eighth period should follow the pattern set by the earlier periods or not, as calculations predict that by this point relativistic effects should result in significant deviations from the Madelung rule. Various different models have been suggested. All agree that the eighth period should begin like the previous ones with two 8s elements, and that there should then follow a new series of g-block elements filling up the 5g orbitals, but the precise configurations calculated for these 5g elements vary widely between sources. Beyond this 5g series, calculations do not agree on what exactly should follow. Filling of the 5g, 6f, 7d, and 8p shells is expected to occur in approximately that order, but they are likely to be intermingled with each other and with the 9s and 9p subshells, so that it is not clear which elements should go in which groups anymore. Scerri has raised the question of whether an extended periodic table should take into account the failure of the Madelung rule in this region, or if such exceptions should be ignored. The shell structure may also be fairly formal at this point: already the electron distribution in an oganesson atom is expected to be rather uniform, with no discernible shell structure. Nuclear stability will likely prove a decisive factor constraining the number of possible elements. It depends on the balance between the electric repulsion between protons and the strong force binding protons and neutrons together. Protons and neutrons are arranged in shells, just like electrons, and so a closed shell can significantly increase stability: the known superheavy nuclei exist because of such a shell closure. They are probably close to a predicted island of stability, where superheavy nuclides should have significantly longer half-lives: predictions range from minutes or days, to millions or billions of years. However, as the number of protons increases beyond about 126, this stabilising effect should vanish as a closed shell is passed. It is not clear if any further-out shell closures exist, due to an expected smearing out of distinct nuclear shells (as is already expected for the electron shells at oganesson). Furthermore, even if later shell closures exist, it is not clear if they would allow such heavy elements to exist. Alternatively, quark matter may become stable at high mass numbers, in which the nucleus is composed of freely flowing up and down quarks instead of binding them into protons and neutrons; this would create a continent of stability instead of an island. Other effects may come into play: for example, in very heavy elements the 1s electrons are likely to spend a significant amount of time so close to the nucleus that they are actually inside it, which would make them vulnerable to electron capture. Even if eighth-row elements can exist, producing them is likely to be difficult, and it should become even more difficult as atomic number rises. Although the 8s elements are expected to be reachable with present means, the first few 5g elements are expected to require new technology, if they can be produced at all. Experimentally characterising these elements chemically would also pose a great challenge. Alternative periodic tables The periodic law may be represented in multiple ways, of which the standard periodic table is only one. Within 100 years of the appearance of Mendeleev's table in 1869, Edward G. Mazurs had collected an estimated 700 different published versions of the periodic table. Many forms retain the rectangular structure, including Janet's left-step periodic table (pictured below), and the modernised form of Mendeleev's original 8-column layout that is still common in Russia. Other periodic table formats have been shaped much more exotically, such as spirals (Otto Theodor Benfey's pictured to the right), circles, triangles, and even elephants. Alternative periodic tables are often developed to highlight or emphasize chemical or physical properties of the elements that are not as apparent in traditional periodic tables, with different ones skewed more towards emphasizing chemistry or physics at either end. The standard form, which remains by far the most common, is somewhere in the middle. The many different forms of the periodic table have prompted the questions of whether there is an optimal or definitive form of the periodic table, and if so what it might be. There are no current consensus answers to either question, though several forms have been suggested as optimal.

health problems such as stomach pain and diarrhoea. Previously the Adequate Intake for adults was set at 4,700 mg per day. In 2019, the National Academies of Sciences, Engineering, and Medicine revised the AI for potassium to 2,600 mg/day for females 19 years and older and 3,400 mg/day for males 19 years and older. Food sources Potassium is present in all fruits, vegetables, meat and fish. Foods with high potassium concentrations include yam, parsley, dried apricots, milk, chocolate, all nuts (especially almonds and pistachios), potatoes, bamboo shoots, bananas, avocados, coconut water, soybeans, and bran. The USDA lists tomato paste, orange juice, beet greens, white beans, potatoes, plantains, bananas, apricots, and many other dietary sources of potassium, ranked in descending order according to potassium content. A day's worth of potassium is in 5 plantains or 11 bananas. Deficient intake Diets low in potassium can lead to hypertension and hypokalemia. Supplementation Supplements of potassium are most widely used in conjunction with diuretics that block reabsorption of sodium and water upstream from the distal tubule (thiazides and loop diuretics), because this promotes increased distal tubular potassium secretion, with resultant increased potassium excretion. A variety of prescription and over-the counter supplements are available. Potassium chloride may be dissolved in water, but the salty/bitter taste makes liquid supplements unpalatable. Typical doses range from 10mmol (400mg), to 20mmol (800mg). Potassium is also available in tablets or capsules, which are formulated to allow potassium to leach slowly out of a matrix, since very high concentrations of potassium ion that occur adjacent to a solid tablet can injure the gastric or intestinal mucosa. For this reason, non-prescription potassium pills are limited by law in the US to a maximum of 99mg of potassium. Since the kidneys are the site of potassium excretion, individuals with impaired kidney function are at risk for hyperkalemia if dietary potassium and supplements are not restricted. The more severe the impairment, the more severe is the restriction necessary to avoid hyperkalemia. A meta-analysis concluded that a 1640mg increase in the daily intake of potassium was associated with a 21% lower risk of stroke. Potassium chloride and potassium bicarbonate may be useful to control mild hypertension. In 2017, potassium was the 37th most commonly prescribed medication in the United States, with more than 19 million prescriptions. Detection by taste buds Potassium can be detected by taste because it triggers three of the five types of taste sensations, according to concentration. Dilute solutions of potassium ions taste sweet, allowing moderate concentrations in milk and juices, while higher concentrations become increasingly bitter/alkaline, and finally also salty to the taste. The combined bitterness and saltiness of high-potassium solutions makes high-dose potassium supplementation by liquid drinks a palatability challenge. Commercial production Mining Potassium salts such as carnallite, langbeinite, polyhalite, and sylvite form extensive evaporite deposits in ancient lake bottoms and seabeds, making extraction of potassium salts in these environments commercially viable. The principal source of potassium – potash – is mined in Canada, Russia, Belarus, Kazakhstan, Germany, Israel, United States, Jordan, and other places around the world. The first mined deposits were located near Staßfurt, Germany, but the deposits span from Great Britain over Germany into Poland. They are located in the Zechstein and were deposited in the Middle to Late Permian. The largest deposits ever found lie below the surface of the Canadian province of Saskatchewan. The deposits are located in the Elk Point Group produced in the Middle Devonian. Saskatchewan, where several large mines have operated since the 1960s pioneered the technique of freezing of wet sands (the Blairmore formation) to drive mine shafts through them. The main potash mining company in Saskatchewan until its merge was the Potash Corporation of Saskatchewan, now Nutrien. The water of the Dead Sea is used by Israel and Jordan as a source of potash, while the concentration in normal oceans is too low for commercial production at current prices. Chemical extraction Several methods are used to separate potassium salts from sodium and magnesium compounds. The most-used method is fractional precipitation using the solubility differences of the salts. Electrostatic separation of the ground salt mixture is also used in some mines. The resulting sodium and magnesium waste is either stored underground or piled up in slag heaps. Most of the mined potassium mineral ends up as potassium chloride after processing. The mineral industry refers to potassium chloride either as potash, muriate of potash, or simply MOP. Pure potassium metal can be isolated by electrolysis of its hydroxide in a process that has changed little since it was first used by Humphry Davy in 1807. Although the electrolysis process was developed and used in industrial scale in the 1920s, the thermal method by reacting sodium with potassium chloride in a chemical equilibrium reaction became the dominant method in the 1950s. The production of sodium potassium alloys is accomplished by changing the reaction time and the amount of sodium used in the reaction. The Griesheimer process employing the reaction of potassium fluoride with calcium carbide was also used to produce potassium. Na + KCl → NaCl + K (Thermal method) 2 KF + → 2 K + + 2 C (Griesheimer process) Reagent-grade potassium metal costs about $10.00/pound ($22/kg) in 2010 when purchased by the tonne. Lower purity metal is considerably cheaper. The market is volatile because long-term storage of the metal is difficult. It must be stored in a dry inert gas atmosphere or anhydrous mineral oil to prevent the formation of a surface layer of potassium superoxide, a pressure-sensitive explosive that detonates when scratched. The resulting explosion often starts a fire difficult to extinguish. Cation identification Potassium is now quantified by ionization techniques, but at one time it was quantitated by gravimetric analysis. Reagents used to precipitate potassium salts include sodium tetraphenylborate, hexachloroplatinic acid, and sodium cobaltinitrite into respectively potassium tetraphenylborate, potassium hexachloroplatinate, and potassium cobaltinitrite. The reaction with sodium cobaltinitrite is illustrative: 3K+ + Na3[Co(NO2)6] → K3[Co(NO2)6] + 3Na+ The potassium cobaltinitrite is obtained as a yellow solid. Commercial uses Fertilizer Potassium ions are an essential component of plant nutrition and are found in most soil types. They are used as a fertilizer in agriculture, horticulture, and hydroponic culture in the form of chloride (KCl), sulfate (), or nitrate (), representing the 'K' in 'NPK'. Agricultural fertilizers consume 95% of global potassium chemical production, and about 90% of this potassium is supplied as KCl. The potassium content of most plants ranges from 0.5% to 2% of the harvested weight of crops, conventionally expressed as amount of . Modern high-yield agriculture depends upon fertilizers to replace the potassium lost at harvest. Most agricultural fertilizers contain potassium chloride, while potassium sulfate is used for chloride-sensitive crops or crops needing higher sulfur content. The sulfate is produced mostly by decomposition of the complex minerals kainite () and langbeinite (). Only a very few fertilizers contain potassium nitrate. In 2005, about 93% of world potassium production was consumed by the fertilizer industry. Furthermore, potassium can play a key role in nutrient cycling by controlling litter composition. Medical use Potassium, in the form of potassium chloride is used as a medication to treat and prevent low blood potassium. Low blood potassium may occur due to vomiting, diarrhea, or certain medications. It is given by slow injection into a vein or by mouth. Food additives Potassium sodium tartrate (, Rochelle salt) is a main constituent of some varieties of baking powder; it is also used in the silvering of mirrors. Potassium bromate () is a strong oxidizer (E924), used to improve dough strength and rise height. Potassium bisulfite () is used as a food preservative, for example in wine and beer-making (but not in meats). It is also used to bleach textiles and straw, and in the tanning of leathers. Industrial Major potassium chemicals are potassium hydroxide, potassium carbonate, potassium sulfate, and potassium chloride. Megatons of these compounds are produced annually. Potassium hydroxide is a strong base, which is used in industry to neutralize strong and weak acids, to control pH and to manufacture potassium salts. It is also used to saponify fats and oils, in industrial cleaners, and in hydrolysis reactions, for example of esters. Potassium nitrate () or saltpeter is obtained from natural sources such as guano and evaporites or manufactured via the Haber process; it is the oxidant in gunpowder (black powder) and an important agricultural fertilizer. Potassium cyanide (KCN) is used industrially to dissolve copper and precious metals, in particular silver and gold, by forming complexes. Its applications include gold mining, electroplating, and electroforming of these metals; it is also used in organic synthesis to make nitriles. Potassium carbonate ( or potash) is used in the manufacture of glass, soap, color TV tubes, fluorescent lamps, textile dyes and pigments. Potassium permanganate () is an oxidizing, bleaching and purification substance and is used for production of saccharin. Potassium chlorate () is added to matches and explosives. Potassium bromide (KBr) was formerly used as a sedative and in photography. While potassium chromate () is used in the manufacture of a host of different commercial products such as inks, dyes, wood stains (by reacting with the tannic acid in wood), explosives, fireworks, fly paper, and safety matches,as well as in the tanning of leather, all of these uses are due to the chemistry of the chromate ion rather than to that of the potassium ion. Niche uses There are thousands of uses of various potassium compounds. One example is potassium superoxide, , an orange solid that acts as a portable source of oxygen and a carbon dioxide absorber. It is widely used in respiration systems in mines, submarines and spacecraft as it takes less volume than the gaseous oxygen. 4 + 2 → 2 + 3 Another example is potassium cobaltinitrite, , which is used as artist's pigment | a result of prompt and efficient clearance by both renal and extra-renal mechanisms. Hypokalemia, a deficiency of potassium in the plasma, can be fatal if severe. Common causes are increased gastrointestinal loss (vomiting, diarrhea), and increased renal loss (diuresis). Deficiency symptoms include muscle weakness, paralytic ileus, ECG abnormalities, decreased reflex response; and in severe cases, respiratory paralysis, alkalosis, and cardiac arrhythmia. Control mechanisms Potassium content in the plasma is tightly controlled by four basic mechanisms, which have various names and classifications. The four are 1) a reactive negative-feedback system, 2) a reactive feed-forward system, 3) a predictive or circadian system, and 4) an internal or cell membrane transport system. Collectively, the first three are sometimes termed the "external potassium homeostasis system"; and the first two, the "reactive potassium homeostasis system". The reactive negative-feedback system refers to the system that induces renal secretion of potassium in response to a rise in the plasma potassium (potassium ingestion, shift out of cells, or intravenous infusion.) The reactive feed-forward system refers to an incompletely understood system that induces renal potassium secretion in response to potassium ingestion prior to any rise in the plasma potassium. This is probably initiated by gut cell potassium receptors that detect ingested potassium and trigger vagal afferent signals to the pituitary gland. The predictive or circadian system increases renal secretion of potassium during mealtime hours (e.g. daytime for humans, nighttime for rodents) independent of the presence, amount, or absence of potassium ingestion. It is mediated by a circadian oscillator in the suprachiasmatic nucleus of the brain (central clock), which causes the kidney (peripheral clock) to secrete potassium in this rhythmic circadian fashion. The ion transport system moves potassium across the cell membrane using two mechanisms. One is active and pumps sodium out of, and potassium into, the cell. The other is passive and allows potassium to leak out of the cell. Potassium and sodium cations influence fluid distribution between intracellular and extracellular compartments by osmotic forces. The movement of potassium and sodium through the cell membrane is mediated by the Na+/K+-ATPase pump. This ion pump uses ATP to pump three sodium ions out of the cell and two potassium ions into the cell, creating an electrochemical gradient and electromotive force across the cell membrane. The highly selective potassium ion channels (which are tetramers) are crucial for hyperpolarization inside neurons after an action potential is triggered, to cite one example. The most recently discovered potassium ion channel is KirBac3.1, which makes a total of five potassium ion channels (KcsA, KirBac1.1, KirBac3.1, KvAP, and MthK) with a determined structure. All five are from prokaryotic species. Renal filtration, reabsorption, and excretion Renal handling of potassium is closely connected to sodium handling. Potassium is the major cation (positive ion) inside animal cells [150mmol/L, (4.8g)], while sodium is the major cation of extracellular fluid [150mmol/L, (3.345g)]. In the kidneys, about 180liters of plasma is filtered through the glomeruli and into the renal tubules per day. This filtering involves about 600g of sodium and 33g of potassium. Since only 1–10g of sodium and 1–4g of potassium are likely to be replaced by diet, renal filtering must efficiently reabsorb the remainder from the plasma. Sodium is reabsorbed to maintain extracellular volume, osmotic pressure, and serum sodium concentration within narrow limits. Potassium is reabsorbed to maintain serum potassium concentration within narrow limits. Sodium pumps in the renal tubules operate to reabsorb sodium. Potassium must be conserved, but because the amount of potassium in the blood plasma is very small and the pool of potassium in the cells is about 30 times as large, the situation is not so critical for potassium. Since potassium is moved passively in counter flow to sodium in response to an apparent (but not actual) Donnan equilibrium, the urine can never sink below the concentration of potassium in serum except sometimes by actively excreting water at the end of the processing. Potassium is excreted twice and reabsorbed three times before the urine reaches the collecting tubules. At that point, urine usually has about the same potassium concentration as plasma. At the end of the processing, potassium is secreted one more time if the serum levels are too high. With no potassium intake, it is excreted at about 200mg per day until, in about a week, potassium in the serum declines to a mildly deficient level of 3.0–3.5mmol/L. If potassium is still withheld, the concentration continues to fall until a severe deficiency causes eventual death. The potassium moves passively through pores in the cell membrane. When ions move through Ion transporters (pumps) there is a gate in the pumps on both sides of the cell membrane and only one gate can be open at once. As a result, approximately 100 ions are forced through per second. Ion channel have only one gate, and there only one kind of ion can stream through, at 10 million to 100 million ions per second. Calcium is required to open the pores, although calcium may work in reverse by blocking at least one of the pores. Carbonyl groups inside the pore on the amino acids mimic the water hydration that takes place in water solution by the nature of the electrostatic charges on four carbonyl groups inside the pore. Nutrition Dietary recommendations The U.S. National Academy of Medicine (NAM), on behalf of both the U.S. and Canada, sets Estimated Average Requirements (EARs) and Recommended Dietary Allowances (RDAs), or Adequate Intakes (AIs) for when there is not sufficient information to set EARs and RDAs. Collectively the EARs, RDAs, AIs and ULs are referred to as Dietary Reference Intakes. For both males and females under 9 years of age, the AIs for potassium are: 400mg of potassium for 0-6-month-old infants, 860mg of potassium for 7-12-month-old infants, 2,000mg of potassium for 1-3-year-old children, and 2,300mg of potassium for 4-8-year-old children. For males 9 years of age and older, the AIs for potassium are: 2,500mg of potassium for 9-13-year-old males, 3,000mg of potassium for 14-18-year-old males, and 3,400mg for males that are 19 years of age and older. For females 9 years of age and older, the AIs for potassium are: 2,300mg of potassium for 9-18-year-old females, and 2,600mg of potassium for females that are 19 years of age and older. For pregnant and lactating females, the AIs for potassium are: 2,600mg of potassium for 14-18-year-old pregnant females, 2,900mg for pregnant females that are 19 years of age and older; furthermore, 2,500mg of potassium for 14-18-year-old lactating females, and 2,800mg for lactating females that are 19 years of age and older. As for safety, the NAM also sets tolerable upper intake levels (ULs) for vitamins and minerals, but for potassium the evidence was insufficient, so no UL was established. As of 2004, most Americans adults consume less than 3,000mg. Likewise, in the European Union, in particular in Germany and Italy, insufficient potassium intake is somewhat common. The British National Health Service recommends a similar intake, saying that adults need 3,500mg per day and that excess amounts may cause health problems such as stomach pain and diarrhoea. Previously the Adequate Intake for adults was set at 4,700 mg per day. In 2019, the National Academies of Sciences, Engineering, and Medicine revised the AI for potassium to 2,600 mg/day for females 19 years and older and 3,400 mg/day for males 19 years and older.

a red mantle, mozzetta, camauro and shoes, and a white cassock and stockings. Many contemporary portraits of 15th and 16th-century predecessors of Pius V show them wearing a white cassock similar to his. Status and authority Development First Vatican Council The status and authority of the pope in the Catholic Church was dogmatically defined by the First Vatican Council on 18 July 1870. In its Dogmatic Constitution of the Church of Christ, the council established the following canons: If anyone says that the blessed Apostle Peter was not established by the Lord Christ as the chief of all the apostles, and the visible head of the whole militant Church, or, that the same received great honour but did not receive from the same our Lord Jesus Christ directly and immediately the primacy in true and proper jurisdiction: let him be anathema. If anyone says that it is not from the institution of Christ the Lord Himself, or by divine right that the blessed Peter has perpetual successors in the primacy over the universal Church, or that the Roman Pontiff is not the successor of blessed Peter in the same primacy, let him be anathema. If anyone thus speaks, that the Roman pontiff has only the office of inspection or direction, but not the full and supreme power of jurisdiction over the universal Church, not only in things which pertain to faith and morals, but also in those which pertain to the discipline and government of the Church spread over the whole world; or, that he possesses only the more important parts, but not the whole plenitude of this supreme power; or that this power of his is not ordinary and immediate, or over the churches altogether and individually, and over the pastors and the faithful altogether and individually: let him be anathema. We, adhering faithfully to the tradition received from the beginning of the Christian faith, to the glory of God, our Saviour, the elevation of the Catholic religion and the salvation of Christian peoples, with the approbation of the sacred Council, teach and explain that the dogma has been divinely revealed: that the Roman Pontiff, when he speaks ex cathedra, that is, when carrying out the duty of the pastor and teacher of all Christians by his supreme apostolic authority he defines a doctrine of faith or morals to be held by the universal Church, through the divine assistance promised him in blessed Peter, operates with that infallibility with which the divine Redeemer wished that His church be instructed in defining doctrine on faith and morals; and so such definitions of the Roman Pontiff from himself, but not from the consensus of the Church, are unalterable. But if anyone presumes to contradict this definition of Ours, which may God forbid: let him be anathema. Second Vatican Council In its Dogmatic Constitution on the Church (1964), the Second Vatican Council declared: On 11 October 2012, on the occasion of the 50th anniversary of the opening of the Second Vatican Council 60 prominent theologians, (including Hans Küng), put out a Declaration, stating that the intention of Vatican II to balance authority in the Church has not been realised. "Many of the key insights of Vatican II have not at all, or only partially, been implemented... A principal source of present-day stagnation lies in misunderstanding and abuse affecting the exercise of authority in our Church." Politics of the Holy See Residence and jurisdiction The pope's official seat is in the Archbasilica of Saint John Lateran, considered the cathedral of the Diocese of Rome, and his official residence is the Apostolic Palace. He also possesses a summer residence at Castel Gandolfo, situated on the site of the ancient city of Alba Longa. Until the time of the Avignon Papacy, the residence of the pope was the Lateran Palace, donated by Roman emperor Constantine the Great. The pope's ecclesiastical jurisdiction (the Holy See) is distinct from his secular jurisdiction (Vatican City). It is the Holy See that conducts international relations; for hundreds of years, the papal court (the Roman Curia) has functioned as the government of the Catholic Church. The names "Holy See" and "Apostolic See" are ecclesiastical terminology for the ordinary jurisdiction of the bishop of Rome (including the Roman Curia); the pope's various honors, powers, and privileges within the Catholic Church and the international community derive from his Episcopate of Rome in lineal succession from the Saint Peter, one of the twelve apostles. Consequently, Rome has traditionally occupied a central position in the Catholic Church, although this is not necessarily so. The pope derives his pontificate from being the bishop of Rome but is not required to live there; according to the Latin formula ubi Papa, ibi Curia, wherever the pope resides is the central government of the Church. As such, between 1309 and 1378, the popes lived in Avignon, France, a period often called the "Babylonian captivity" in allusion to the Biblical narrative of Jews of the ancient Kingdom of Judah living as captives in Babylonia. Though the pope is the diocesan bishop of Rome, he delegates most of the day-to-day work of leading the diocese to the cardinal vicar, who assures direct episcopal oversight of the diocese's pastoral needs, not in his own name but in that of the pope. The current cardinal vicar is Angelo De Donatis, who was appointed to the office in June 2017. Political role Though the progressive Christianisation of the Roman Empire in the 4th century did not confer upon bishops civil authority within the state, the gradual withdrawal of imperial authority during the 5th century left the pope the senior imperial civilian official in Rome, as bishops were increasingly directing civil affairs in other cities of the Western Empire. This status as a secular and civil ruler was vividly displayed by Pope Leo I's confrontation with Attila in 452. The first expansion of papal rule outside of Rome came in 728 with the Donation of Sutri, which in turn was substantially increased in 754, when the Frankish ruler Pippin the Younger gave to the pope the land from his conquest of the Lombards. The pope may have utilized the forged Donation of Constantine to gain this land, which formed the core of the Papal States. This document, accepted as genuine until the 15th century, states that Constantine the Great placed the entire Western Empire of Rome under papal rule. In 800, Pope Leo III crowned the Frankish ruler Charlemagne as Roman emperor, a major step toward establishing what later became known as the Holy Roman Empire; from that date onward the popes claimed the prerogative to crown the emperor, though the right fell into disuse after the coronation of Charles V in 1530. Pius VII was present at the coronation of Napoleon I in 1804 but did not actually perform the crowning. As mentioned above, the pope's sovereignty over the Papal States ended in 1870 with their annexation by Italy. Popes like Alexander VI, an ambitious if spectacularly corrupt politician, and Julius II, a formidable general and statesman, were not afraid to use power to achieve their own ends, which included increasing the power of the papacy. This political and temporal authority was demonstrated through the papal role in the Holy Roman Empire (especially prominent during periods of contention with the emperors, such as during the pontificates of Pope Gregory VII and Pope Alexander III). Papal bulls, interdict, and excommunication (or the threat thereof) have been used many times to exercise papal power. The bull Laudabiliter in 1155 authorized King Henry II of England to invade Ireland. In 1207, Innocent III placed England under interdict until King John made his kingdom a fiefdom to the Pope, complete with yearly tribute, saying, "we offer and freely yield...to our lord Pope Innocent III and his catholic successors, the whole kingdom of England and the whole kingdom of Ireland with all their rights and appurtenences for the remission of our sins". The Bull Inter caetera in 1493 led to the Treaty of Tordesillas in 1494, which divided the world into areas of Spanish and Portuguese rule. The bull Regnans in Excelsis in 1570 excommunicated Queen Elizabeth I of England and declared that all her subjects were released from allegiance to her. The bull Inter gravissimas in 1582 established the Gregorian calendar. International position Under international law, a serving head of state has sovereign immunity from the jurisdiction of the courts of other countries, though not from that of international tribunals. This immunity is sometimes loosely referred to as "diplomatic immunity", which is, strictly speaking, the immunity enjoyed by the diplomatic representatives of a head of state. International law treats the Holy See, essentially the central government of the Catholic Church, as the juridical equal of a state. It is distinct from the state of Vatican City, existing for many centuries before the foundation of the latter. (It is common for publications and news media to use "the Vatican", "Vatican City", and even "Rome" as metonyms for the Holy See.) Most countries of the world maintain the same form of diplomatic relations with the Holy See that they entertain with other states. Even countries without those diplomatic relations participate in international organizations of which the Holy See is a full member. It is as head of the state-equivalent worldwide religious jurisdiction of the Holy See (not of the territory of Vatican City) that the U.S. Justice Department ruled that the pope enjoys head-of-state immunity. This head-of-state immunity, recognized by the United States, must be distinguished from that envisaged under the United States' Foreign Sovereign Immunities Act of 1976, which, while recognizing the basic immunity of foreign governments from being sued in American courts, lays down nine exceptions, including commercial activity and actions in the United States by agents or employees of the foreign governments. It was in relation to the latter that, in November 2008, the United States Court of Appeals in Cincinnati decided that a case over sexual abuse by Catholic priests could proceed, provided the plaintiffs could prove that the bishops accused of negligent supervision were acting as employees or agents of the Holy See and were following official Holy See policy. In April 2010, there was press coverage in Britain concerning a proposed plan by atheist campaigners and a prominent barrister to have Pope Benedict XVI arrested and prosecuted in the UK for alleged offences, dating from several decades before, in failing to take appropriate action regarding Catholic sex abuse cases and concerning their disputing his immunity from prosecution in that country. This was generally dismissed as "unrealistic and spurious". Another barrister said that it was a "matter of embarrassment that a senior British lawyer would want to allow himself to be associated with such a silly idea". Objections to the papacy The pope's claim to authority is either disputed or rejected outright by other churches, for various reasons. Orthodox, Anglican and Old Catholic churches Other traditional Christian churches (Assyrian Church of the East, the Oriental Orthodox Church, the Eastern Orthodox Church, the Old Catholic Church, the Anglican Communion, the Independent Catholic churches, etc.) accept the doctrine of Apostolic succession and, to varying extents, papal claims to a primacy of honour, while generally rejecting the pope as the successor to Peter in any other sense than that of other bishops. Primacy is regarded as a consequence of the pope's position as bishop of the original capital city of the Roman Empire, a definition explicitly spelled out in the 28th canon of the Council of Chalcedon. These churches see no foundation to papal claims of universal immediate jurisdiction, or to claims of papal infallibility. Several of these churches refer to such claims as ultramontanism. Protestant denominations In 1973, the United States Conference of Catholic Bishops' Committee on Ecumenical and Interreligious Affairs and the USA National Committee of the Lutheran World Federation in the official Catholic–Lutheran dialogue included this passage in a larger statement on papal primacy: Protestant denominations of Christianity reject the claims of Petrine primacy of honor, Petrine primacy of jurisdiction, and papal infallibility. These denominations vary from denying the legitimacy of the pope's claim to authority, to believing that the pope is the Antichrist from 1 John 2:18, the Man of Sin from 2 Thessalonians 2:3–12, and the Beast out of the Earth from Revelation 13:11–18. This sweeping rejection is held by, among others, some denominations of Lutherans: Confessional Lutherans hold that the pope is the Antichrist, stating that this article of faith is part of a quia ("because") rather than quatenus ("insofar as") subscription to the Book of Concord. In 1932, one of these Confessional churches, the Lutheran Church–Missouri Synod (LCMS), adopted A Brief Statement of the Doctrinal Position of the Missouri Synod, which a small number of Lutheran church bodies now hold. The Lutheran Churches of the Reformation, the Concordia Lutheran Conference, the Church of the Lutheran Confession, and the Illinois Lutheran Conference all hold to the Brief Statement, which the LCMS places on its website. The Wisconsin Evangelical Lutheran Synod (WELS), another Confessional Lutheran church that declares the Papacy to be the Antichrist, released its own statement, the "Statement on the Antichrist", in 1959. The WELS still holds to this statement. Historically, Protestants objected to the papacy's claim of temporal power over all secular governments, including territorial claims in Italy, the papacy's complex relationship with secular states such as the Roman and Byzantine empires, and the autocratic character of the papal office. In Western Christianity these objections both contributed to and are products of the Protestant Reformation. Antipopes Groups sometimes form around antipopes, who claim the Pontificate without being canonically and properly elected to it. Traditionally, this term was reserved for claimants with a significant following of cardinals or other clergy. The existence of an antipope is usually due either to doctrinal controversy within the Church (heresy) or to confusion as to who is the legitimate pope at the time (schism). Briefly in the 15th century, three separate lines of popes claimed authenticity. Even Catholics do not all agree whether certain historical figures were popes or antipopes. Though antipope movements were significant at one time, they are now overwhelmingly minor fringe causes. Other uses of the title "Pope" In the earlier centuries of Christianity, the title "Pope", meaning "father", had been used by all bishops. Some popes used the term and others did not. Eventually, the title became associated especially with the Bishop of Rome. In a few cases, the term is used for other Christian clerical authorities. In English, Catholic priests are still addressed as "father", but the term "pope" is reserved for the head of the church hierarchy. In the Catholic Church "Black Pope" is a name that was popularly, but unofficially, given to the superior general of the Society of Jesus due to the Jesuits' importance within the Church. This name, based on the black colour of his cassock, was used to suggest a parallel between him and the "White Pope" (since the time of Pius V the popes dress in white) and the cardinal prefect of the Congregation for the Evangelization of Peoples (formerly called the Sacred Congregation for the Propagation of the Faith), whose red cardinal's cassock gave him the name of the "Red Pope" in view of the authority over all territories that were not considered in some way Catholic. In the present time this cardinal has power over mission territories for Catholicism, essentially the Churches of Africa and Asia, but in the past his competence extended also to all lands where Protestants or Eastern Christianity was dominant. Some remnants of this situation remain, with the result that, for instance, New Zealand is still in the care of this Congregation. In the Eastern Churches Since the papacy of Heraclas in the 3rd century, the bishop of Alexandria in both the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria continues to be called "pope", the former being called "Coptic pope" or, more properly, "Pope and Patriarch of All Africa on the Holy Orthodox and Apostolic Throne of Saint Mark the Evangelist and Holy Apostle" and the latter called "Pope and Patriarch of Alexandria and All Africa". In the Bulgarian Orthodox Church, Russian Orthodox Church and Serbian Orthodox Church, it is not unusual for a village priest to be called a "pope" ("поп" pop). However, this should be differentiated from the words used for the head of the Catholic Church (Bulgarian "папа" papa, Russian "папа римский" papa rimskiy). In new religious movements and other Christian-related new religious movements Some new religious movements within Christianity, especially those that have disassociated themselves from the Catholic Church yet retain a Catholic hierarchical framework, have used the designation "pope" for a founder or current leader. Examples include the African Legio Maria Church and the European Palmarian Catholic Church in Spain. The Cao Dai, a Vietnamese faith that duplicates the Catholic hierarchy, is similarly headed by a pope. Lengths of papal reign Longest-reigning popes Although the average reign of the pope from the Middle Ages was a decade, a number of those whose reign lengths can be determined from contemporary historical data are the following: St. Peter (c. 30–64/68): c. 34 – c. 38 years (12,410–13,870 days) Bl. Pius IX (1846–1878): 31 years, 7 months and 23 days (11,560 days) St. John Paul II (1978–2005): 26 years, 5 months and 18 days (9,665 days) Leo XIII (1878–1903): 25 years, 5 months and 1 day (9,281 days) Pius VI (1775–1799): 24 years, | died in the 20th and 21st centuries have been interred in St. Peter's Basilica. A nine-day period of mourning (novendialis) follows the interment. Resignation It is highly unusual for a pope to resign. The 1983 Code of Canon Law states, "If it happens that the Roman Pontiff resigns his office, it is required for validity that the resignation is made freely and properly manifested but not that it is accepted by anyone." Benedict XVI, who vacated the Holy See on 28 February 2013, was the most recent to do so since Gregory XII's resignation in 1415. Titles Regnal name Popes adopt a new name on their accession, known as papal name, in Italian and Latin. Currently, after a new pope is elected and accepts the election, he is asked "By what name shall you be called?". The new pope chooses the name by which he will be known from that point on. The senior cardinal deacon, or cardinal protodeacon, then appears on the balcony of Saint Peter's to proclaim the new pope by his birth name, and announce his papal name in Latin. It's customary when referring to popes to translate the regnal name into all local languages. For example, the current pope bears the papal name Papa Franciscus in Latin and Papa Francesco in Italian, but Papa Francisco in his native Spanish, Pope Francis in English, etc. Official list of titles The official list of titles of the pope, in the order in which they are given in the Annuario Pontificio, is: The best-known title, that of "pope", does not appear in the official list, but is commonly used in the titles of documents, and appears, in abbreviated form, in their signatures. Thus Paul VI signed as "Paulus PP. VI", the "PP." standing for "papa pontifex" ("pope and pontiff"). The title "pope" was from the early 3rd century an honorific designation used for any bishop in the West. In the East, it was used only for the bishop of Alexandria. Marcellinus (d. 304) is the first bishop of Rome shown in sources to have had the title "pope" used of him. From the 6th century, the imperial chancery of Constantinople normally reserved this designation for the bishop of Rome. From the early 6th century, it began to be confined in the West to the bishop of Rome, a practice that was firmly in place by the 11th century, when Pope Gregory VII declared it reserved for the bishop of Rome. In Eastern Christianity, where the title "pope" is used also of the bishop of Alexandria, the bishop of Rome is often referred to as the "pope of Rome", regardless of whether the speaker or writer is in communion with Rome or not. Vicar of Jesus Christ "Vicar of Jesus Christ" (Vicarius Iesu Christi) is one of the official titles of the pope given in the Annuario Pontificio. It is commonly used in the slightly abbreviated form "vicar of Christ" (vicarius Christi). While it is only one of the terms with which the pope is referred to as "vicar", it is "more expressive of his supreme headship of the Church on Earth, which he bears in virtue of the commission of Christ and with vicarial power derived from him", a vicarial power believed to have been conferred on Saint Peter when Christ said to him: "Feed my lambs...Feed my sheep". The first record of the application of this title to a bishop of Rome appears in a synod of 495 with reference to Gelasius I. But at that time, and down to the 9th century, other bishops too referred to themselves as vicars of Christ, and for another four centuries this description was sometimes used of kings and even judges, as it had been used in the 5th and 6th centuries to refer to the Byzantine emperor. Earlier still, in the 3rd century, Tertullian used "vicar of Christ" to refer to the Holy Spirit sent by Jesus. Its use specifically for the pope appears in the 13th century in connection with the reforms of Pope Innocent III, as can be observed already in his 1199 letter to Leo I, King of Armenia. Other historians suggest that this title was already used in this way in association with the pontificate of Eugene III (1145–1153). This title "vicar of Christ" is thus not used of the pope alone and has been used of all bishops since the early centuries. The Second Vatican Council referred to all bishops as "vicars and ambassadors of Christ", and this description of the bishops was repeated by John Paul II in his encyclical Ut unum sint, 95. The difference is that the other bishops are vicars of Christ for their own local churches, the pope is vicar of Christ for the whole Church. On at least one occasion the title "vicar of God" (a reference to Christ as God) was used of the pope. The title "vicar of Peter" (vicarius Petri) is used only of the pope, not of other bishops. Variations of it include: "Vicar of the Prince of the Apostles" (Vicarius Principis Apostolorum) and "Vicar of the Apostolic See" (Vicarius Sedis Apostolicae). Saint Boniface described Pope Gregory II as vicar of Peter in the oath of fealty that he took in 722. In today's Roman Missal, the description "vicar of Peter" is found also in the collect of the Mass for a saint who was a pope. Supreme pontiff The term "pontiff" is derived from the , which literally means "bridge builder" (pons + facere) and which designated a member of the principal college of priests in ancient Rome. The Latin word was translated into ancient Greek variously: as , , , (hierophant), or (archiereus, high priest) The head of the college was known as the (the greatest pontiff). In Christian use, pontifex appears in the Vulgate translation of the New Testament to indicate the High Priest of Israel (in the original Koine Greek, ). The term came to be applied to any Christian bishop, but since the 11th century commonly refers specifically to the bishop of Rome, who is more strictly called the "Roman Pontiff". The use of the term to refer to bishops in general is reflected in the terms "Roman Pontifical" (a book containing rites reserved for bishops, such as confirmation and ordination), and "pontificals" (the insignia of bishops). The Annuario Pontificio lists as one of the official titles of the pope that of "Supreme Pontiff of the Universal Church" (). He is also commonly called the Supreme Pontiff or the Sovereign Pontiff (). Pontifex Maximus, similar in meaning to Summus Pontifex, is a title commonly found in inscriptions on papal buildings, paintings, statues and coins, usually abbreviated as "Pont. Max" or "P.M." The office of Pontifex Maximus, or head of the College of Pontiffs, was held by Julius Caesar and thereafter, by the Roman emperors, until Gratian (375–383) relinquished it. Tertullian, when he had become a Montanist, used the title derisively of either the pope or the bishop of Carthage. The popes began to use this title regularly only in the 15th century. Servant of the servants of God Although the description "servant of the servants of God" () was also used by other Church leaders, including Augustine of Hippo and Benedict of Nursia, it was first used extensively as a papal title by Gregory the Great, reportedly as a lesson in humility for the patriarch of Constantinople, John the Faster, who had assumed the title "ecumenical patriarch". It became reserved for the pope in the 12th century and is used in papal bulls and similar important papal documents. Patriarch of the West From 1863 until 2005, the Annuario Pontificio also included the title "patriarch of the West". This title was first used by Pope Theodore I in 642, and was only used occasionally. Indeed, it did not begin to appear in the pontifical yearbook until 1863. On 22 March 2006, the Vatican released a statement explaining this omission on the grounds of expressing a "historical and theological reality" and of "being useful to ecumenical dialogue". The title patriarch of the West symbolized the pope's special relationship with, and jurisdiction over, the Latin Church—and the omission of the title neither symbolizes in any way a change in this relationship, nor distorts the relationship between the Holy See and the Eastern Churches, as solemnly proclaimed by the Second Vatican Council. Other titles Other titles commonly used are "His Holiness" (either used alone or as an honorific prefix as in "His Holiness Pope Francis"; and as "Your Holiness" as a form of address), "Holy Father". In Spanish and Italian, "Beatísimo/Beatissimo Padre" (Most Blessed Father) is often used in preference to "Santísimo/Santissimo Padre" (Most Holy Father). In the medieval period, "Dominus Apostolicus" ("the Apostolic Lord") was also used. Signature Pope Francis signs some documents with his name alone, either in Latin ("Franciscus", as in an encyclical dated 29 June 2013) or in another language. Other documents he signs in accordance with the tradition of using Latin only and including the abbreviated form "PP.", for the Latin Papa ("Pope"). Popes who have an ordinal numeral in their name traditionally place the abbreviation "PP." before the ordinal numeral, as in "Benedictus PP. XVI" (Pope Benedict XVI), except in papal bulls of canonization and decrees of ecumenical councils, which a pope signs with the formula, "Ego N. Episcopus Ecclesiae catholicae", without the numeral, as in "Ego Benedictus Episcopus Ecclesiae catholicae" (I, Benedict, Bishop of the Catholic Church). The pope's signature is followed, in bulls of canonization, by those of all the cardinals resident in Rome, and in decrees of ecumenical councils, by the signatures of the other bishops participating in the council, each signing as Bishop of a particular see. Papal bulls are headed N. Episcopus Servus Servorum Dei ("Name, Bishop, Servant of the Servants of God"). In general, they are not signed by the pope, but John Paul II introduced in the mid-1980s the custom by which the pope signs not only bulls of canonization but also, using his normal signature, such as "Benedictus PP. XVI", bulls of nomination of bishops. Regalia and insignia Triregnum, also called the "tiara" or "triple crown", represents the pope's three functions as "supreme pastor", "supreme teacher" and "supreme priest". Recent popes have not, however, worn the triregnum, though it remains the symbol of the papacy and has not been abolished. In liturgical ceremonies the pope wears an episcopal mitre (an erect cloth hat). Crosier topped by a crucifix, a custom established before the 13th century (see Papal ferula). Pallium, or pall, a circular band of fabric worn around the neck over the chasuble. It forms a yoke about the neck, breast and shoulders and has two pendants hanging down in front and behind, and is ornamented with six crosses. Previously, the pallium worn by the pope was identical to those he granted to the primates, but in 2005, Pope Benedict XVI began to use a distinct papal pallium that is larger than the primatial, and was adorned with red crosses instead of black. "Keys to the Kingdom of Heaven", the image of two keys, one gold and one silver. The silver key symbolizes the power to bind and loose on Earth, and the gold key the power to bind and loose in Heaven. Ring of the Fisherman, a gold or gilt ring decorated with a depiction of St. Peter in a boat casting his net, with the pope's name around it. Umbraculum (better known in the Italian form ombrellino) is a canopy or umbrella consisting of alternating red and gold stripes, which used to be carried above the pope in processions. Sedia gestatoria, a mobile throne carried by twelve footmen (palafrenieri) in red uniforms, accompanied by two attendants bearing flabella (fans made of white ostrich feathers), and sometimes a large canopy, carried by eight attendants. The use of the flabella was discontinued by Pope John Paul I. The use of the sedia gestatoria was discontinued by Pope John Paul II. In heraldry, each pope has his own personal coat of arms. Though unique for each pope, the arms have for several centuries been traditionally accompanied by two keys in saltire (i.e., crossed over one another so as to form an X) behind the escutcheon (shield) (one silver key and one gold key, tied with a red cord), and above them a silver triregnum with three gold crowns and red infulae (lappets—two strips of fabric hanging from the back of the triregnum which fall over the neck and shoulders when worn). This is blazoned: "two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or". The 21st century has seen departures from this tradition. In 2005, Pope Benedict XVI, while maintaining the crossed keys behind the shield, omitted the papal tiara from his personal coat of arms, replacing it with a mitre with three horizontal lines. Beneath the shield he added the pallium, a papal symbol of authority more ancient than the tiara, the use of which is also granted to metropolitan archbishops as a sign of communion with the See of Rome. Although the tiara was omitted in the pope's personal coat of arms, the coat of arms of the Holy See, which includes the tiara, remained unaltered. In 2013, Pope Francis maintained the mitre that replaced the tiara, but omitted the pallium. He also departed from papal tradition by adding beneath the shield his personal pastoral motto: Miserando atque eligendo. The flag most frequently associated with the pope is the yellow and white flag of Vatican City, with the arms of the Holy See (blazoned: "Gules, two keys in saltire or and argent, interlacing in the rings or, beneath a tiara argent, crowned or") on the right-hand side (the "fly") in the white half of the flag (the left-hand side—the "hoist"—is yellow). The pope's escucheon does not appear on the flag. This flag was first adopted in 1808, whereas the previous flag had been red and gold. Although Pope Benedict XVI replaced the triregnum with a mitre on his personal coat of arms, it has been retained on the flag. Papal garments Pope Pius V (reigned 1566–1572), is often credited with having originated the custom whereby the pope wears white, by continuing after his election to wear the white habit of the Dominican order. In reality, the basic papal attire was white long before. The earliest document that describes it as such is the Ordo XIII, a book of ceremonies compiled in about 1274. Later books of ceremonies describe the pope as wearing a red mantle, mozzetta, camauro and shoes, and a white cassock and stockings. Many contemporary portraits of 15th and 16th-century predecessors of Pius V show them wearing a white cassock similar to his. Status and authority Development First Vatican Council The status and authority of the pope in the Catholic Church was dogmatically defined by the First Vatican Council on 18 July 1870. In its Dogmatic Constitution of the Church of Christ, the council established the following canons: If anyone says that the blessed Apostle Peter was not established by the Lord Christ as the chief of all the apostles, and the visible head of the whole militant Church, or, that the same received great honour but did not receive from the same our Lord Jesus Christ directly and immediately the primacy in true and proper jurisdiction: let him be anathema. If anyone says that it is not from the institution of Christ the Lord Himself, or by divine right that the blessed Peter has perpetual successors in the primacy over the universal Church, or that the Roman Pontiff is not the successor of blessed Peter in the same primacy, let him be anathema. If anyone thus speaks, that the Roman pontiff has only the office of inspection or direction, but not the full and supreme power of jurisdiction over the universal Church, not only in things which pertain to faith and morals, but also in those which pertain to the discipline and government of the Church spread over the whole world; or, that he possesses only the more important parts, but not the whole plenitude of this supreme power; or that this power of his is not ordinary and immediate, or over the churches altogether and individually, and over the pastors and the faithful altogether and individually: let him be anathema. We, adhering faithfully to the tradition received from the beginning of the Christian faith, to the glory of God, our Saviour, the elevation of the Catholic religion and the salvation of Christian peoples, with the approbation of the sacred Council, teach and explain that the dogma has been divinely revealed: that the Roman Pontiff, when he speaks ex cathedra, that is, when carrying out the duty of the pastor and teacher of all Christians by his supreme apostolic authority he defines a doctrine of faith or morals to be held by the universal Church, through the divine assistance promised him in blessed Peter, operates with that infallibility with which the divine Redeemer wished that His church be instructed in defining doctrine on faith and morals; and so such definitions of the Roman Pontiff from himself, but not from the consensus of the Church, are unalterable. But if anyone presumes to contradict this definition of Ours, which may God forbid: let him be anathema. Second Vatican Council In its Dogmatic Constitution on the Church (1964), the Second Vatican Council declared: On 11 October 2012, on the occasion of the 50th anniversary of the opening of the Second Vatican Council 60 prominent theologians, (including Hans Küng), put out a Declaration, stating that the intention of Vatican II to balance authority in the Church has not been realised. "Many of the key insights of Vatican II have not at all, or only partially, been implemented... A principal source of present-day stagnation lies in misunderstanding and abuse affecting the exercise of authority in our Church." Politics of the Holy See Residence and jurisdiction The pope's official seat is in the Archbasilica of Saint John Lateran, considered the cathedral of the Diocese of Rome, and his official residence is the Apostolic Palace. He also possesses a summer residence at Castel Gandolfo, situated on the site of the ancient city of Alba Longa. Until the time of the Avignon Papacy, the residence of the pope was the Lateran Palace, donated by Roman emperor Constantine the Great. The pope's ecclesiastical jurisdiction (the Holy See) is distinct from his secular jurisdiction (Vatican City). It is the Holy See that conducts international relations; for hundreds of years, the papal court (the Roman Curia) has functioned as the government of the Catholic Church. The names "Holy See" and "Apostolic See" are ecclesiastical terminology for the ordinary jurisdiction of the bishop of Rome (including the Roman Curia); the pope's various honors, powers, and privileges within the Catholic Church and the international community derive from his Episcopate of Rome in lineal succession from the Saint Peter, one of the twelve apostles. Consequently, Rome has traditionally occupied a central position in the Catholic Church, although this is not necessarily so. The pope derives his pontificate from being the bishop of Rome but is not required to live there; according to the Latin formula ubi Papa, ibi Curia, wherever the pope resides is the central government of the Church. As such, between 1309 and 1378, the popes lived in Avignon, France, a period often called the "Babylonian captivity" in allusion to the Biblical narrative of Jews of the ancient Kingdom of Judah living as captives in Babylonia. Though the pope is the diocesan bishop of Rome, he delegates most of the day-to-day work of leading the diocese to the cardinal vicar, who assures direct episcopal oversight of the diocese's pastoral needs, not in his own name but in that of the pope. The current cardinal vicar is Angelo De Donatis, who was appointed to the office in June 2017. Political role Though the progressive Christianisation of the Roman Empire in the 4th century did not confer upon bishops civil authority within the state, the gradual withdrawal of imperial authority during the 5th century left the pope the senior imperial civilian official in Rome, as bishops were increasingly directing civil affairs in other cities of the Western Empire. This status as a secular and civil ruler was vividly displayed by Pope Leo I's confrontation with Attila in 452. The first expansion of papal rule outside of Rome came in 728 with the Donation of Sutri, which in turn was substantially increased in 754, when the Frankish ruler Pippin the Younger gave to the pope the land from his conquest of the Lombards. The pope may have utilized the forged Donation of Constantine to gain this land, which formed the core of the Papal States. This document, accepted as genuine until the 15th century, states that Constantine the Great placed the entire Western Empire of Rome under papal rule. In 800, Pope Leo III crowned the Frankish ruler Charlemagne as Roman emperor, a major step toward establishing what later became known as the Holy Roman Empire; from that date onward the popes claimed the prerogative to crown the emperor, though the right fell into disuse after the coronation of Charles V in 1530. Pius VII was present at the coronation of Napoleon I in 1804 but did not actually perform the crowning. As mentioned above, the pope's sovereignty over the Papal States ended in 1870 with their annexation by Italy. Popes like Alexander VI, an ambitious if spectacularly corrupt politician, and Julius II, a formidable general and statesman, were not afraid to use power to achieve their own ends, which included increasing the power of the papacy. This political and temporal authority was demonstrated through the papal role in the Holy Roman Empire (especially prominent during periods of contention with the emperors, such as during the pontificates of Pope Gregory VII and Pope Alexander III). Papal bulls, interdict, and excommunication (or the threat thereof) have been used many times to exercise papal power. The bull Laudabiliter in 1155 authorized King Henry II of England to invade Ireland. In 1207, Innocent III placed England under interdict until King John made his kingdom a fiefdom to the Pope, complete with yearly tribute, saying, "we offer and freely yield...to our lord Pope Innocent III and his catholic successors, the whole kingdom of England and the whole kingdom of Ireland with all their rights and appurtenences for the remission of our sins". The Bull Inter caetera in 1493 led to the Treaty of Tordesillas in 1494, which divided the world into areas of Spanish and Portuguese rule. The bull Regnans in Excelsis in 1570 excommunicated Queen Elizabeth I of England and declared that all her subjects were released from allegiance to her. The bull Inter gravissimas in 1582 established the Gregorian calendar. International position Under international law, a serving head of state has sovereign immunity from the jurisdiction of the courts of other countries, though not from that of international tribunals. This immunity is sometimes loosely referred to as "diplomatic immunity", which is, strictly speaking, the immunity enjoyed by the diplomatic representatives of a head of state. International law treats the Holy See, essentially the central government of the Catholic Church, as the juridical equal of a state. It is distinct from the state of Vatican City, existing for many centuries before the foundation of the latter. (It is common for publications and news media to use "the Vatican", "Vatican City", and even "Rome" as metonyms for the Holy See.) Most countries of the world maintain the same form of diplomatic relations with the Holy See that they entertain with other states. Even countries without those diplomatic relations participate in international organizations of which the Holy See is a full member. It is as head of the state-equivalent worldwide religious jurisdiction of the Holy See (not of the territory of Vatican City) that the U.S. Justice Department ruled that the pope enjoys head-of-state immunity. This head-of-state immunity, recognized by the United States, must be distinguished from that envisaged under the United States' Foreign Sovereign Immunities Act of 1976, which, while recognizing the basic immunity of foreign governments from being sued in American courts, lays down nine exceptions, including commercial activity and actions in the United States by agents or employees of the foreign governments. It was in relation to the latter that, in November 2008, the United States Court of Appeals in Cincinnati decided that a case over sexual abuse by Catholic priests could proceed, provided the plaintiffs could prove that the bishops accused of negligent supervision were acting as employees or agents of the Holy See and were following official Holy See policy. In April 2010, there was press coverage in Britain concerning a proposed plan by atheist campaigners and a prominent barrister to have Pope Benedict XVI arrested and prosecuted in the UK for alleged offences, dating from several decades before, in failing to take appropriate action regarding Catholic sex abuse cases and concerning their disputing his immunity from prosecution in that country. This was generally dismissed as "unrealistic and spurious". Another barrister said that it was a "matter of embarrassment that a senior British lawyer would want to allow himself to be associated with such a silly idea". Objections to the papacy The pope's claim to authority is either disputed or rejected outright by other churches, for various reasons. Orthodox, Anglican and Old Catholic churches Other traditional Christian churches (Assyrian Church of the East, the Oriental Orthodox Church, the Eastern Orthodox Church, the Old Catholic Church, the Anglican Communion, the Independent Catholic churches, etc.) accept the doctrine of Apostolic succession and, to varying extents, papal claims to a primacy of honour, while generally rejecting the pope as the successor to Peter in any other sense than that of other bishops. Primacy is regarded as a consequence of the pope's position as bishop of the original capital city of the Roman Empire, a definition explicitly spelled out in the 28th canon of the Council of Chalcedon. These churches see no foundation to papal claims of universal immediate jurisdiction, or to claims of papal infallibility. Several of these churches refer to such claims as ultramontanism. Protestant denominations In 1973, the United States Conference of Catholic Bishops' Committee on Ecumenical and Interreligious Affairs and the USA National Committee of the Lutheran World Federation in the official Catholic–Lutheran dialogue included this passage in a larger statement on papal primacy: Protestant denominations of Christianity reject the claims of Petrine primacy of honor, Petrine primacy of jurisdiction, and papal infallibility. These denominations vary from denying the legitimacy of the pope's claim to authority, to believing that the pope is the Antichrist from 1 John 2:18, the Man of Sin from 2 Thessalonians 2:3–12, and the Beast out of the Earth from Revelation 13:11–18. This sweeping rejection is held by, among others, some denominations of Lutherans: Confessional Lutherans hold that the pope is the Antichrist, stating that this article of faith is part of a quia ("because") rather than quatenus ("insofar as") subscription to the Book of Concord. In 1932, one of these Confessional churches, the Lutheran Church–Missouri Synod (LCMS), adopted A Brief Statement of the Doctrinal Position of the Missouri Synod, which a small number of Lutheran church bodies now hold. The Lutheran Churches of the Reformation, the Concordia Lutheran Conference, the Church of the Lutheran Confession, and the Illinois Lutheran Conference all hold to the Brief Statement, which the LCMS places on its website. The Wisconsin Evangelical Lutheran Synod (WELS), another Confessional Lutheran church that declares the Papacy to be the Antichrist, released its own statement, the "Statement on the Antichrist", in 1959. The WELS still holds to this statement. Historically, Protestants objected to the papacy's claim of temporal power over all secular governments, including territorial claims in Italy, the papacy's complex relationship with secular states such as the Roman and Byzantine empires, and the autocratic character of the papal office. In Western Christianity these objections both contributed to and are products of the Protestant Reformation. Antipopes Groups sometimes form around antipopes, who claim the Pontificate without being canonically and properly elected to it. Traditionally, this term was reserved for claimants with a significant following of cardinals or other clergy. The existence of an antipope is usually due either to doctrinal controversy within the Church (heresy) or to confusion as to who is the legitimate pope at the time (schism). Briefly in the 15th century, three separate lines of popes claimed authenticity. Even Catholics do not all agree whether certain historical figures were popes or antipopes. Though antipope movements were significant at one time, they are now overwhelmingly minor fringe causes. Other uses of the title "Pope" In the earlier centuries of Christianity, the title "Pope", meaning "father", had been used by all bishops. Some popes used the term and others did not. Eventually, the title became associated especially with the Bishop of Rome. In a few cases, the term is used for other Christian clerical authorities. In English, Catholic priests are still addressed as "father", but the term "pope" is reserved for the head of the church hierarchy. In the Catholic Church "Black Pope" is a name that was popularly, but unofficially, given to the superior general of the Society of Jesus due to the Jesuits' importance within the Church. This name, based on the black colour of his cassock, was used to suggest a parallel between him and the "White Pope" (since the time of Pius V the popes dress in white) and the cardinal prefect of the Congregation for the Evangelization of Peoples (formerly called the Sacred Congregation for the Propagation of the Faith), whose red cardinal's cassock gave him the name of the "Red Pope" in view of the authority over all territories that were not considered in some way Catholic. In the present time this cardinal has power over mission territories for Catholicism, essentially the Churches of Africa and Asia, but in the past his competence extended also to all lands where Protestants or Eastern Christianity was dominant. Some remnants of this situation remain, with the result that, for instance, New Zealand is still in the care of this Congregation. In the Eastern Churches Since the papacy of Heraclas in the 3rd century, the bishop of Alexandria in both the Coptic Orthodox |
to turn off the lights and conduct the search by candlelight, using a feather and a wooden spoon: candlelight effectively illuminates corners without casting shadows; the feather can dust crumbs out of their hiding places; and the wooden spoon which collects the crumbs can be burned the next day with the chametz. However, most contemporary Jewish-Orthodox authorities permit using a flashlight, while some strongly encourage it due to the danger coupled with using a candle. Because the house is assumed to have been thoroughly cleaned by the night before Passover, there is some concern that making a blessing over the search for chametz will be in vain (bracha l'vatala) if nothing is found. Thus, 10 morsels of bread or cereal smaller than the size of an olive are traditionally hidden throughout the house in order to ensure that some chametz will be found. Upon conclusion of the search, with all the small pieces safely wrapped up and put in one bag or place, to be burned the next morning, the following is said: Any chametz or leaven that is in my possession which I have not seen and have not removed and do not know about should be annulled and become ownerless like the dust of the earth. Original declaration as recited in Aramaic: כל חמירא וחמיעא דאכא ברשותי דלא חמתה ודלא בערתה ודלא ידענא לה לבטל ולהוי הפקר כעפרא דארעא Morning of 14th of Nisan Note that if the 14th of Nisan is Shabbat, many of the below will be celebrated on the 13th instead due to restrictions in place during Shabbat. Fast of the Firstborn On the day preceding the first Passover seder (or on Thursday morning preceding the seder, when the first seder falls on Motza'ei Shabbat), firstborn sons are commanded to celebrate the Fast of the Firstborn which commemorates the salvation of the Hebrew firstborns. According to Exodus 12:29, God struck down all Egyptian firstborns while the Israelites were not affected. However, it is customary for synagogues to conduct a siyum (ceremony marking the completion of a section of Torah learning) right after morning prayers, and the celebratory meal that follows cancels the firstborn's obligation to fast. Burning and nullification of leaven On the morning of the 14th of Nisan, any leavened products that remain in the householder's possession, along with the 10 morsels of bread from the previous night's search, are burned (s'rayfat chametz). The head of the household repeats the declaration of biyur chametz, declaring any chametz that may not have been found to be null and void "as the dust of the earth": Any chametz or leaven that is in my possession which I have not seen and have not removed and do not know about should be annulled and become ownerless like the dust of the earth. Original declaration as recited in Aramaic: כל חמירא וחמיעא דאכא ברשותי דלא חמתה ודלא בערתה ודלא ידענא לה לבטל ולהוי הפקר כעפרא דארעא Should more chametz actually be found in the house during the Passover holiday, it must be burnt as soon as possible. Unlike chametz, which can be eaten any day of the year except during Passover, kosher for Passover foods can be eaten year-round. They need not be burnt or otherwise discarded after the holiday ends. The historic "Paschal lamb" Passover sacrifice (Korban Pesach) has not been brought following the Romans' destruction of the Second Jewish temple approximately two thousand years ago, and it is therefore still not part of the modern Jewish holiday. In the times when the Jewish Temples stood, the lamb was slaughtered and cooked on the evening of Passover and was completely consumed before the morning as described in Exodus 12:3–11. Separate kosher for Passover utensils and dishes Due to the Torah injunction not to eat chametz (leaven) during Passover, observant families typically own complete sets of serving dishes, glassware and silverware (and in some cases, even separate dishwashers and sinks) which have never come into contact with chametz, for use only during Passover. Under certain circumstances, some chametz utensils can be immersed in boiling water (hagalat keilim) to purge them of any traces of chametz that may have accumulated during the year. Many Sephardic families thoroughly wash their year-round glassware and then use it for Passover, as the Sephardic position is that glass does not absorb enough traces of food to present a problem. Similarly, ovens may be used for Passover either by setting the self-cleaning function to the highest degree for a certain period of time, or by applying a blow torch to the interior until the oven glows red hot (a process called libun gamur). Matzah A symbol of the Passover holiday is matzo, an unleavened flatbread made solely from flour and water which is continually worked from mixing through baking, so that it is not allowed to rise. Matzo may be made by machine or by hand. The Torah contains an instruction to eat matzo, specifically, on the first night of Passover and to eat only unleavened bread (in practice, matzo) during the entire week of Passover. Consequently, the eating of matzo figures prominently in the Passover Seder. There are several explanations for this. The Torah says that it is because the Hebrews left Egypt with such haste that there was no time to allow baked bread to rise; thus flat, unleavened bread, matzo, is a reminder of the rapid departure of the Exodus. Other scholars teach that in the time of the Exodus, matzo was commonly baked for the purpose of traveling because it preserved well and was light to carry (making it similar to hardtack), suggesting that matzo was baked intentionally for the long journey ahead. Matzo has also been called Lechem Oni (Hebrew: "bread of poverty"). There is an attendant explanation that matzo serves as a symbol to remind Jews what it is like to be a poor slave and to promote humility, appreciate freedom, and avoid the inflated ego symbolized by more luxurious leavened bread. Shmura matzo ("watched" or "guarded" matzo), is the bread of preference for the Passover Seder in Orthodox Jewish communities. Shmura matzo is made from wheat that is guarded from contamination by leaven (chametz) from the time of summer harvest to its baking into matzos five to ten months later. In the weeks before Passover, matzos are prepared for holiday consumption. In many Orthodox Jewish communities, men traditionally gather in groups ("chaburas") to bake handmade matzo for use at the Seder, the dough being rolled by hand, resulting in a large and round matzo. Chaburas also work together in machine-made matzo factories, which produce the typically square-shaped matzo sold in stores. The baking of matzo is labor-intensive, as less than 18 minutes is permitted between the mixing of flour and water to the conclusion of baking and removal from the oven. Consequently, only a small number of matzos can be baked at one time, and the chabura members are enjoined to work the dough constantly so that it is not allowed to ferment and rise. A special cutting tool is run over the dough just before baking to prick any bubbles which might make the matza puff up; this creates the familiar dotted holes in the matzo. After the matzos come out of the oven, the entire work area is scrubbed down and swept to make sure that no pieces of old, potentially leavened dough remain, as any stray pieces are now chametz, and can contaminate the next batch of matzo. Some machine-made matzos are completed within 5 minutes of being kneaded. Passover seder It is traditional for Jewish families to gather on the first night of Passover (first two nights in Orthodox and Conservative communities outside Israel) for a special dinner called a seder (Hebrew: סדר seder – derived from the Hebrew word for "order" or "arrangement", referring to the very specific order of the ritual). The table is set with the finest china and silverware to reflect the importance of the meal. During this meal, the story of the Exodus from Egypt is retold using a special text called the Haggadah. Four cups of wine are consumed at various stages in the narrative. The Haggadah divides the night's procedure into 15 parts: Kadeish/ Qadēsh קדש – recital of Kiddush blessing and drinking of the first cup of wine Urchatz/ Ūr·ḥats/ Ūr·ḥaṣ ורחץ – the washing of the hands – without blessing Karpas כרפס – dipping of the karpas in salt water Yachatz/ Yaḥats/ Yaḥaṣ יחץ – breaking the middle matzo; the larger piece becomes the afikoman which is eaten later during the ritual of Tzafun Maggid/ Maggiyd מגיד – retelling the Passover story, including the recital of "the four questions" and drinking of the second cup of wine Rachtzah/ Raḥ·tsah/ Raḥ·ṣah רחצה – second washing of the hands – with blessing Motzi/ Môtsiy’/ Môṣiy’ מוציא – traditional blessing before eating bread products Matzo/ Maṣo מצה – blessing before eating matzo Maror מרור – eating of the maror Koreich/ Korēkh כורך – eating of a sandwich made of matzo and maror Shulchan oreich/ Shūl·ḥan ‘ôrēkh שולחן עורך – lit. "set table" – the serving of the holiday meal Tzafun/ Tsafūn/ Ṣafūn צפון – eating of the afikoman Bareich/ Barēkh ברך – blessing after the meal and drinking of the third cup of wine Hallel הלל – recital of the Hallel, traditionally recited on festivals; drinking of the fourth cup of wine Nirtzah/ Niyr·tsah/ Niyr·ṣah נירצה – conclusion These 15 parts parallel the 15 steps in the Temple in Jerusalem on which the Levites stood during Temple services, and which were memorialized in the 15 Psalms (#120–134) known as Shir HaMa'a lot (Hebrew: shiyr ha-ma‘alôth, "Songs of Ascent"). The seder is replete with questions, answers, and unusual practices (e.g. the recital of Kiddush which is not immediately followed by the blessing over bread, which is the traditional procedure for all other holiday meals) to arouse the interest and curiosity of the children at the table. The children are also rewarded with nuts and candies when they ask questions and participate in the discussion of the Exodus and its aftermath. Likewise, they are encouraged to search for the afikoman, the piece of matzo which is the last thing eaten at the seder. Audience participation and interaction is the rule, and many families' seders last long into the night with animated discussions and much singing. The seder concludes with additional songs of praise and faith printed in the Haggadah, including Chad Gadya ("One Little Kid" or "One Little Goat"). Maror Maror (bitter herbs) symbolizes the bitterness of slavery in Egypt. The following verse from the Torah underscores that symbolism: "And they embittered (Hebrew: וימררו ve-yimareru) their lives with hard labor, with mortar and with bricks and with all manner of labor in the field; any labor that they made them do was with hard labor" (Exodus 1:14). Four cups of wine There is a Rabbinic requirement that four cups of wine are to be drunk during the seder meal. This applies to both men and women. The Mishnah says (Pes. 10:1) that even the poorest man in Israel has an obligation to drink. Each cup is connected to a different part of the seder: the first cup is for Kiddush, the second cup is connected with the recounting of the Exodus, the drinking of the third cup concludes Birkat Hamazon and the fourth cup is associated with Hallel. The four questions and participation of children Children have a very important role in the Passover seder. Traditionally the youngest child is prompted to ask questions about the Passover seder, beginning with the words, Mah Nishtana HaLeila HaZeh (Why is this night different from all other nights?). The questions encourage the gathering to discuss the significance of the symbols in the meal. The questions asked by the child are: Why is this night different from all other nights? On all other nights, we eat either unleavened or leavened bread, but tonight we eat only unleavened bread? On all other nights, we eat all kinds of vegetables, but tonight, we eat only bitter herbs? On all other nights, we do not dip [our food] even once, but tonight we dip twice? On all other nights, we eat either sitting or reclining, but tonight we only recline? Often the leader of the seder and the other adults at the meal will use prompted responses from the Haggadah, which states, "The more one talks about the Exodus from Egypt, the more praiseworthy he is." Many readings, prayers, and stories are used to recount the story of the Exodus. Many households add their own commentary and interpretation and often the story of the Jews is related to the theme of liberation and its implications worldwide. Afikoman The afikoman – an integral part of the Seder itself – is used to engage the interest and excitement of the children at the table. During the fourth part of the Seder, called Yachatz, the leader breaks the middle piece of matzo into two. He sets aside the larger portion as the afikoman. Many families use the afikoman as a device for keeping the children awake and alert throughout the Seder proceedings by hiding the afikoman and offering a prize for its return. Alternatively, the children are allowed to "steal" the afikoman and demand a reward for its return. In either case, the afikoman must be consumed during the twelfth part of the Seder, Tzafun. Concluding songs After the | search is conducted on the preceding Thursday night (thirteenth of Nisan) as chametz cannot be burned during Shabbat. The Talmud in Pesahim (p. 2a) derives from the Torah that the search for chametz be conducted by the light of a candle and therefore is done at night, and although the final destruction of the chametz (usually by burning it in a small bonfire) is done on the next morning, the blessing is made at night because the search is both in preparation for and part of the commandments to remove and destroy all chametz from one's possession. Blessing for search of chametz and nullification of chametz Before the search is begun there is a special blessing. If several people or family members assist in the search then only one person, usually the head of that family recites the blessing having in mind to include everyone present: Blessed are You, Hashem our God, King of the universe, Who has sanctified us with his commandments and has commanded us concerning the removal of chametz. In Hebrew: ברוך אתה י-הוה א-להינו מלך העולם אשר קדשנו במצותיו וצונו על בעור חמץ (berūkh otah, Adoynoy E-lohaynū, melekh ha-‘ôlam, eser qedesh-nū be-mitsūtayu we-tsewinū ‘al be-ôr ḥamets) The search is then usually conducted by the head of the household joined by his family including children under the supervision of their parents. It is customary to turn off the lights and conduct the search by candlelight, using a feather and a wooden spoon: candlelight effectively illuminates corners without casting shadows; the feather can dust crumbs out of their hiding places; and the wooden spoon which collects the crumbs can be burned the next day with the chametz. However, most contemporary Jewish-Orthodox authorities permit using a flashlight, while some strongly encourage it due to the danger coupled with using a candle. Because the house is assumed to have been thoroughly cleaned by the night before Passover, there is some concern that making a blessing over the search for chametz will be in vain (bracha l'vatala) if nothing is found. Thus, 10 morsels of bread or cereal smaller than the size of an olive are traditionally hidden throughout the house in order to ensure that some chametz will be found. Upon conclusion of the search, with all the small pieces safely wrapped up and put in one bag or place, to be burned the next morning, the following is said: Any chametz or leaven that is in my possession which I have not seen and have not removed and do not know about should be annulled and become ownerless like the dust of the earth. Original declaration as recited in Aramaic: כל חמירא וחמיעא דאכא ברשותי דלא חמתה ודלא בערתה ודלא ידענא לה לבטל ולהוי הפקר כעפרא דארעא Morning of 14th of Nisan Note that if the 14th of Nisan is Shabbat, many of the below will be celebrated on the 13th instead due to restrictions in place during Shabbat. Fast of the Firstborn On the day preceding the first Passover seder (or on Thursday morning preceding the seder, when the first seder falls on Motza'ei Shabbat), firstborn sons are commanded to celebrate the Fast of the Firstborn which commemorates the salvation of the Hebrew firstborns. According to Exodus 12:29, God struck down all Egyptian firstborns while the Israelites were not affected. However, it is customary for synagogues to conduct a siyum (ceremony marking the completion of a section of Torah learning) right after morning prayers, and the celebratory meal that follows cancels the firstborn's obligation to fast. Burning and nullification of leaven On the morning of the 14th of Nisan, any leavened products that remain in the householder's possession, along with the 10 morsels of bread from the previous night's search, are burned (s'rayfat chametz). The head of the household repeats the declaration of biyur chametz, declaring any chametz that may not have been found to be null and void "as the dust of the earth": Any chametz or leaven that is in my possession which I have not seen and have not removed and do not know about should be annulled and become ownerless like the dust of the earth. Original declaration as recited in Aramaic: כל חמירא וחמיעא דאכא ברשותי דלא חמתה ודלא בערתה ודלא ידענא לה לבטל ולהוי הפקר כעפרא דארעא Should more chametz actually be found in the house during the Passover holiday, it must be burnt as soon as possible. Unlike chametz, which can be eaten any day of the year except during Passover, kosher for Passover foods can be eaten year-round. They need not be burnt or otherwise discarded after the holiday ends. The historic "Paschal lamb" Passover sacrifice (Korban Pesach) has not been brought following the Romans' destruction of the Second Jewish temple approximately two thousand years ago, and it is therefore still not part of the modern Jewish holiday. In the times when the Jewish Temples stood, the lamb was slaughtered and cooked on the evening of Passover and was completely consumed before the morning as described in Exodus 12:3–11.

Under certain circumstances, some chametz utensils can be immersed in boiling water (hagalat keilim) to purge them of any traces of chametz that may have accumulated during the year. Many Sephardic families thoroughly wash their year-round glassware and then use it for Passover, as the Sephardic position is that glass does not absorb enough traces of food to present a problem.

The Haggadah divides the night's procedure into 15 parts: Kadeish/ Qadēsh קדש – recital of Kiddush blessing and drinking of the first cup of wine Urchatz/ Ūr·ḥats/ Ūr·ḥaṣ ורחץ – the washing of the hands – without blessing Karpas כרפס – dipping of the karpas in salt water Yachatz/ Yaḥats/ Yaḥaṣ יחץ – breaking the middle matzo; the larger piece becomes the afikoman which is eaten later during the ritual of Tzafun Maggid/ Maggiyd מגיד – retelling the Passover story, including the recital of "the four questions" and drinking of the second cup of wine Rachtzah/ Raḥ·tsah/ Raḥ·ṣah רחצה – second washing of the hands – with blessing Motzi/ Môtsiy’/ Môṣiy’ מוציא – traditional blessing before eating bread products Matzo/ Maṣo מצה – blessing before eating matzo Maror מרור – eating of the maror Koreich/ Korēkh כורך – eating of a sandwich made of matzo and maror Shulchan oreich/ Shūl·ḥan ‘ôrēkh שולחן עורך – lit. "set table" – the serving of the holiday meal Tzafun/ Tsafūn/ Ṣafūn צפון – eating of the afikoman Bareich/ Barēkh ברך – blessing after the meal and drinking of the third cup of wine Hallel הלל – recital of the Hallel, traditionally recited on festivals; drinking of the fourth cup of wine Nirtzah/ Niyr·tsah/ Niyr·ṣah נירצה – conclusion These 15 parts parallel the 15 steps in the Temple in Jerusalem on which the Levites stood during Temple services, and which were memorialized in the 15 Psalms (#120–134) known as Shir HaMa'a lot (Hebrew: shiyr ha-ma‘alôth, "Songs of Ascent"). The seder is replete with questions, answers, and unusual practices (e.g. the recital of Kiddush which is not immediately followed by the blessing over bread, which is the traditional procedure for all other holiday meals) to arouse the interest and curiosity of the children at the table. The children are also rewarded with nuts and candies when they ask questions and participate in the discussion of the Exodus and its aftermath. Likewise, they are encouraged to search for the afikoman, the piece of matzo which is the last thing eaten at the seder. Audience participation and interaction is the rule, and many families' seders last long into the night with animated discussions and much singing. The seder concludes with additional songs of praise and faith printed in the Haggadah, including Chad Gadya ("One Little Kid" or "One Little Goat"). Maror Maror (bitter herbs) symbolizes the bitterness of slavery in Egypt. The following verse from the Torah underscores that symbolism: "And they embittered (Hebrew: וימררו ve-yimareru) their lives with hard labor, with mortar and with bricks and with all manner of labor in the field; any labor that they made them do was with hard labor" (Exodus 1:14). Four cups of wine There is a Rabbinic requirement that four cups of wine are to be drunk during the seder meal. This applies to both men and women. The Mishnah says (Pes. 10:1) that even the poorest man in Israel has an obligation to drink. Each cup is connected to a different part of the seder: the first cup is for Kiddush, the second cup is connected with the recounting of the Exodus, the drinking of the third cup concludes Birkat Hamazon and the fourth cup is associated with Hallel. The four questions and participation of children Children have a very important role in the Passover seder. Traditionally the youngest child is prompted to ask questions about the Passover seder, beginning with the words, Mah Nishtana HaLeila HaZeh (Why is this night different from all other nights?). The questions encourage the gathering to discuss the significance of the symbols in the meal. The questions asked by the child are: Why is this night different from all other nights? On all other nights, we eat either unleavened or leavened bread, but tonight we eat only unleavened bread? On all other nights, we eat all kinds of vegetables, but tonight, we eat only bitter herbs? On all other nights, we do not dip [our food] even once, but tonight we dip twice? On all other nights, we eat either sitting or reclining, but tonight we only recline? Often the leader of the seder and the other adults at the meal will use prompted responses from the Haggadah, which states, "The more one talks about the Exodus from Egypt, the more praiseworthy he is." Many readings, prayers, and stories are used to recount the story of the Exodus. Many households add their own commentary and interpretation and often the story of the Jews is related to the theme of liberation and its implications worldwide. Afikoman The afikoman – an integral part of the Seder itself – is used to engage the interest and excitement of the children at the table. During the fourth part of the Seder, called Yachatz, the leader breaks the middle piece of matzo into two. He sets aside the larger portion as the afikoman. Many families use the afikoman as a device for keeping the children awake and alert throughout the Seder proceedings by hiding the afikoman and offering a prize for its return. Alternatively, the children are allowed to "steal" the afikoman and demand a reward for its return. In either case, the afikoman must be consumed during the twelfth part of the Seder, Tzafun. Concluding songs After the Hallel, the fourth glass of wine is drunk, and participants recite a prayer that ends in "Next year in Jerusalem!". This is followed by several lyric prayers that expound upon God's mercy and kindness, and give thanks for the survival of the Jewish people through a history of exile and hardship. "Echad Mi Yodea" ("Who Knows One?") is a playful song, testing the general knowledge of the children (and the adults). Some of these songs, such as "Chad Gadya" are allegorical. Counting of the Omer Beginning on the second night of Passover, the 16th day of Nisan, Jews begin the practice of the Counting of the Omer, a nightly reminder of the approach of the holiday of Shavuot 50 days hence. Each night after the evening prayer service, men and women recite a special blessing and then enumerate the day of the Omer. On the first night, for example, they say, "Today is the first day in (or, to) the Omer"; on the second night, "Today is the second day in the Omer." The counting also involves weeks; thus, the seventh day is commemorated, "Today is the seventh day, which is one week in the Omer." The eighth day is marked, "Today is the eighth day, which is one week and one day in the Omer," etc. When the Temple stood in Jerusalem, a sheaf of new-cut barley was presented before the altar on the second day of Unleavened Bread. Josephus writes:On the second day of unleavened bread, that is to say the sixteenth, our people partake of the crops which they have reaped and which have not been touched till then, and esteeming it right first to do homage to God, to whom they owe the abundance of these gifts, they offer to him the first-fruits of the barley in the following way. After parching and crushing the little sheaf of ears and purifying the barley for grinding, they bring to the altar an assaron for God, and, having flung a handful thereof on the altar, they leave the rest for the use of the priests. Thereafter all are permitted, publicly or individually, to begin harvest. Since the destruction of the Temple, this offering is brought in word rather than deed. One explanation for the Counting of the Omer is that it shows the connection between Passover and Shavuot. The |

The highlights of differences are: POP is a simpler protocol, making implementation easier. POP moves the message from the email server to the local computer, although there is usually an option to leave the messages on the email server as well. IMAP defaults to leaving the message on the email server, simply downloading a local copy. POP treats the mailbox as a single store, and has no concept of folders An IMAP client performs complex queries, asking the server for headers, or the bodies of specified messages, or to search for messages meeting certain criteria. Messages in the mail repository can be marked with various status flags (e.g. "deleted" or "answered") and they stay in the repository until explicitly removed by the user—which may not be until a later session. In short: IMAP is designed to permit manipulation of remote mailboxes as if they were local. Depending on the IMAP client implementation and the mail architecture desired by the system manager, the user may save messages directly on the client machine, or save them on the server, or | and its procedures was driven by the need of users having only temporary Internet connections, such as dial-up access, allowing these users to retrieve e-mail when connected, and subsequently to view and manipulate the retrieved messages when offline. POP3 clients also have an option to leave mail on the server after download. By contrast, the Internet Message Access Protocol (IMAP) was designed to normally leave all messages on the server to permit management with multiple client applications, and to support both connected (online) and disconnected (offline) modes of operation. A POP3 server listens on well-known port number 110 for service requests. Encrypted communication for POP3 is either requested after protocol initiation, using the STLS command, if supported, or by POP3S, which connects to the server using Transport Layer Security (TLS) or Secure Sockets Layer (SSL) on well-known TCP port number 995. Messages available to the client are determined when a POP3 session opens the maildrop, and are identified by message-number local to that session or, optionally, by a unique identifier assigned to the message by the POP server. This unique identifier is permanent and unique to the maildrop and allows a client to access the same message in different POP sessions. Mail is retrieved and marked for deletion by the message-number. When the client exits the session, mail marked for deletion is removed from the maildrop. History The first version of the Post Office Protocol, POP1, was specified in RFC 918 (1984). POP2 was specified in RFC 937 (1985). POP3 is the version in most common use. It originated with RFC 1081 (1988) but the most recent specification is RFC 1939, updated with an extension mechanism (RFC 2449) and an authentication mechanism in RFC 1734. This led to a number of POP implementations such as Pine, POPmail, and other early mail clients. While the original POP3 specification supported only an unencrypted USER/PASS login mechanism or Berkeley .rhosts access control, today POP3 supports several authentication methods to provide varying levels of protection against illegitimate access to a user's e-mail. Most are provided by the POP3 extension mechanisms. POP3 clients support SASL authentication methods via the AUTH extension. MIT Project Athena also produced a Kerberized version. RFC 1460 introduced APOP into the core protocol. APOP is a challenge/response protocol which uses the MD5 hash function in an attempt to avoid replay attacks and disclosure of the shared secret. Clients implementing APOP include Mozilla Thunderbird, Opera Mail, Eudora, KMail, Novell Evolution, RimArts' Becky!, Windows Live Mail, PowerMail, Apple Mail, and Mutt. RFC 1460 was obsoleted by RFC 1725, which was in turn obsoleted by RFC 1939. POP4 POP4 exists only as an informal proposal adding basic folder management, multipart message support, as well as message flag management to compete with IMAP; however, its development has not progressed since 2003. Extensions and specifications An extension mechanism was proposed in RFC 2449 to accommodate general extensions as well as announce in an organized manner support for optional commands, such as TOP and UIDL. The RFC did not intend to encourage extensions, and reaffirmed that the role of POP3 is to provide simple support for mainly download-and-delete requirements of mailbox handling. The extensions are termed capabilities and are listed by the CAPA command. With the exception of APOP, the optional commands were included in the initial set of capabilities. Following the lead of ESMTP (RFC 5321), capabilities beginning with an X signify local capabilities. STARTTLS The STARTTLS extension allows the use of Transport Layer Security (TLS) or Secure Sockets Layer (SSL) to be negotiated using the STLS command, on the standard POP3 port, rather than an alternate. Some clients and servers instead use the alternate-port method, which uses TCP port 995 (POP3S). SDPS Demon Internet introduced extensions to POP3 that allow multiple accounts per domain, and has become known as Standard Dial-up POP3 Service (SDPS). To access each account, the username includes the hostname, as john@hostname or john+hostname. Google Apps uses the same method. Kerberized Post Office Protocol In computing, local e-mail clients can use the Kerberized Post Office Protocol (KPOP), an application-layer Internet standard protocol, to retrieve |
established in 1841 by Henry Mayhew and wood-engraver Ebenezer Landells. Historically, it was most influential in the 1840s and 1850s, when it helped to coin the term "cartoon" in its modern sense as a humorous illustration. After the 1940s, when its circulation peaked, it went into a long decline, closing in 1992. It was revived in 1996, but closed again in 2002. History Punch was founded on 17 July 1841 by Henry Mayhew and wood-engraver Ebenezer Landells, on an initial investment of £25. It was jointly edited by Mayhew and Mark Lemon. It was subtitled The London Charivari in homage to Charles Philipon's French satirical humour magazine Le Charivari. Reflecting their satiric and humorous intent, the two editors took for their name and masthead the anarchic glove puppet, Mr. Punch, of Punch and Judy; the name also referred to a joke made early on about one of the magazine's first editors, Lemon, that "punch is nothing without lemon". Mayhew ceased to be joint editor in 1842 and became "suggestor in chief" until he severed his connection in 1845. The magazine initially struggled for readers, except for an 1842 "Almanack" issue which shocked its creators by selling 90,000 copies. In December 1842 due to financial difficulties, the magazine was sold to Bradbury and Evans, both printers and publishers. Bradbury and Evans capitalised on newly evolving mass printing technologies and also were the publishers for Charles Dickens and William Makepeace Thackeray. Cartoon terminology The term "cartoon" to refer to comic drawings was first used in Punch in 1843, when the Houses of Parliament were to be decorated with murals, and "cartoons" for the mural were displayed for the public; the term "cartoon" then meant a finished preliminary sketch on a large piece of cardboard, or in Italian. Punch humorously appropriated the term to refer to its political cartoons, and the popularity of the Punch cartoons led to the term's widespread use. Artistry Illustrator Archibald Henning designed the cover of the magazine's first issues. The cover design varied in the early years, though Richard Doyle designed what became the magazine's masthead in 1849. Artists who published in Punch during the 1840s and '50s included John Leech, Doyle, John Tenniel, and Charles Keene. This group became known as "The Punch Brotherhood", which also included Charles Dickens, who joined Bradbury and Evans after leaving Chapman and Hall in 1843. Punch'''s authors and artists also contributed to another Bradbury and Evans literary magazine called Once A Week (est. 1859), created in response to Dickens' departure | peaked in 1947–1948 at 175,000 to 184,000. Sales declined steadily thereafter; ultimately, the magazine was forced to close in 2002 after 161 years of publication.Punch was widely emulated worldwide and was popular throughout the British Empire. The experience of Britons in British colonies, especially in India, influenced Punch and its iconography. Tenniel's Punch cartoons of the 1857 Sepoy Mutiny led to a surge in the magazine's popularity. India was frequently caricatured in Punch and was an important source of knowledge on the subcontinent for British readers. Later years Punch material was collected in book formats from the late 19th century, which included Pick of the Punch annuals with cartoons and text features, Punch and the War (a 1941 collection of WWII-related cartoons), and A Big Bowl of Punch – which was republished a number of times. Many Punch cartoonists of the late 20th century published collections of their own, partly based on Punch contributions. In early 1996, businessman Mohamed Al-Fayed bought the rights to the name, and Punch was relaunched later that year.Whack! Whack! Whack! Reborn Punch Pounded Warren Hodge, The New York Times, 18 September 1996. Retrieved 16 March 2013. The new version of the magazine was intended to be a spoiler aimed at Private Eye, which had published many items critical of Fayed. Punch never became profitable in its new incarnation, and at the end of May 2002, it was announced as once more ceasing publication. Press reports quoted a loss of £16 million over the six years of publication, with only 6,000 subscribers at the end. Whereas the earlier version of Punch prominently featured the clownish character Punchinello (Punch of Punch and Judy) performing antics on front covers, the resurrected Punch did not use the character, but featured on its weekly covers a photograph of a boxing glove, thus informing its readers that the new magazine intended its name to mean "punch" in the sense of a boxing blow. Punch table In 2004, much of the archives was acquired by the British Library, including the Punch table. The long, oval, Victorian table was brought into the offices some time around 1855, and was used for staff meetings and on other occasions. The wooden surface is scarred with the carved initials of the magazine's longtime writers, artists, and editors, as well as six invited "strangers", including James Thurber and Prince Charles. Mark Twain declined the invitation, saying that the already-carved initials of William Makepeace Thackeray included his own.

University of Pennsylvania humour magazine the Pennsylvania Punch Bowl derived its name from this magazine. Australia's Melbourne Punch was inspired by the London original.

merges with another ridge (south of South America) to form the East Pacific Rise which also connects with another ridge (south of North America) which overlooks the Juan de Fuca Ridge. For most of Magellan's voyage from the Strait of Magellan to the Philippines, the explorer indeed found the ocean peaceful; however, the Pacific is not always peaceful. Many tropical storms batter the islands of the Pacific. The lands around the Pacific Rim are full of volcanoes and often affected by earthquakes. Tsunamis, caused by underwater earthquakes, have devastated many islands and in some cases destroyed entire towns. The Martin Waldseemüller map of 1507 was the first to show the Americas separating two distinct oceans. Later, the Diogo Ribeiro map of 1529 was the first to show the Pacific at about its proper size.

There are about 25,000 islands in the Pacific Ocean. The islands entirely within the Pacific Ocean can be divided into three main groups known as Micronesia, Melanesia and Polynesia. Micronesia, which lies north of the equator and west of the International Date Line, includes the Mariana Islands in the northwest, the Caroline Islands in the center, the Marshall Islands to the east and the islands of Kiribati in the southeast. Melanesia, to the southwest, includes New Guinea, the world's second largest island after Greenland and by far the largest of the Pacific islands. The other main Melanesian groups from north to south are the Bismarck Archipelago, the Solomon Islands, Santa Cruz, Vanuatu, Fiji and New Caledonia. The largest area, Polynesia, stretching from Hawaii in the north to New Zealand in the south, also encompasses Tuvalu, Tokelau, Samoa, Tonga and the Kermadec Islands to the west, the Cook Islands, Society Islands and Austral Islands in the center, and the Marquesas Islands, Tuamotu, Mangareva Islands, and Easter Island to the east. Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs and uplifted coral platforms. Continental islands lie outside the andesite line and include New Guinea, the islands of New Zealand, and the Philippines. Some of these islands are structurally associated with nearby continents. High islands are of volcanic origin, and many contain active volcanoes. Among these are Bougainville, Hawaii, and the Solomon Islands. The coral reefs of the South Pacific are low-lying structures that have built up on basaltic lava flows under the ocean's surface. One of the most dramatic is the Great Barrier Reef off northeastern Australia with chains of reef patches. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba (formerly Ocean Island) and Makatea in the Tuamotu group of French Polynesia. Water characteristics The volume of the Pacific Ocean, representing about 50.1 percent of the world's oceanic water, has been estimated at some . Surface water temperatures in the Pacific can vary from , the freezing point of seawater, in the poleward areas to about near the equator. Salinity also varies latitudinally, reaching a maximum of 37 parts per thousand in the southeastern area. The water near the equator, which can have a salinity as low as 34 parts per thousand, is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year. The lowest counts of less than 32 parts per thousand are found in the far north as less evaporation of seawater takes place in these frigid areas. The motion of Pacific waters is generally clockwise in the Northern Hemisphere (the North Pacific gyre) and counter-clockwise in the Southern Hemisphere. The North Equatorial Current, driven westward along latitude 15°N by the trade winds, turns north near the Philippines to become the warm Japan or Kuroshio Current. Turning eastward at about 45°N, the Kuroshio forks and some water moves northward as the Aleutian Current, while the rest turns southward to rejoin the North Equatorial Current. The Aleutian Current branches as it approaches North America and forms the base of a counter-clockwise circulation in the Bering Sea. Its southern arm becomes the chilled slow, south-flowing California Current. The South Equatorial Current, flowing west along the equator, swings southward east of New Guinea, turns east at about 50°S, and joins the main westerly circulation of the South Pacific, which includes the Earth-circling Antarctic Circumpolar Current. As it approaches the Chilean coast, the South Equatorial Current divides; one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current. Climate The climate patterns of the Northern and Southern Hemispheres generally mirror each other. The trade winds in the southern and eastern Pacific are remarkably steady while conditions in the North Pacific are far more varied with, for example, cold winter temperatures on the east coast of Russia contrasting with the milder weather off British Columbia during the winter months due to the preferred flow of ocean currents. In the tropical and subtropical Pacific, the El Niño Southern Oscillation (ENSO) affects weather conditions. To determine the phase of ENSO, the most recent three-month sea surface temperature average for the area approximately to the southeast of Hawaii is computed, and if the region is more than above or below normal for that period, then an El Niño or La Niña is considered in progress. In the tropical western Pacific, the monsoon and the related wet season during the summer months contrast with dry winds in the winter which blow over the ocean from the Asian landmass. Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest; however, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active month. November is the only month in which all the tropical cyclone basins are active. The Pacific hosts the two most active tropical cyclone basins, which are the northwestern Pacific and the eastern Pacific. Pacific hurricanes form south of Mexico, sometimes striking the western Mexican coast and occasionally the southwestern United States between June and October, while typhoons forming in the northwestern Pacific moving into southeast and east Asia from May to December. Tropical cyclones also form in the South Pacific basin, where they occasionally impact island nations. In the arctic, icing from October to May can present a hazard for shipping while persistent fog occurs from June to December. A climatological low in the Gulf of Alaska keeps the southern coast wet and mild during the winter months. The Westerlies and associated jet stream within the Mid-Latitudes can be particularly strong, especially in the Southern Hemisphere, due to the temperature difference between the tropics and Antarctica, which records the coldest temperature readings on the planet. In the Southern hemisphere, because of the stormy and cloudy conditions associated with extratropical cyclones riding the jet stream, it is usual to refer to the Westerlies as the Roaring Forties, Furious Fifties and Shrieking Sixties according to the varying degrees of latitude. Geology The ocean was first mapped by Abraham Ortelius; he called it Maris Pacifici following Ferdinand Magellan's description of it as "a pacific sea" during his circumnavigation from 1519 to 1522. To Magellan, it seemed much more calm (pacific) than the Atlantic. The andesite line is the most significant regional distinction in the Pacific. A petrologic boundary, it separates the deeper, mafic igneous rock of the Central Pacific Basin from the partially submerged continental areas of felsic igneous rock on its margins. The andesite line follows the western edge of the islands off California and passes south of the Aleutian arc, along the eastern edge of the Kamchatka Peninsula, the Kuril Islands, Japan, the Mariana Islands, the Solomon Islands, and New Zealand's North Island. The dissimilarity continues northeastward along the western edge of the Andes Cordillera along South America to Mexico, returning then to the islands off California. Indonesia, the Philippines, Japan, New Guinea, and New Zealand lie outside the andesite line. Within the closed loop of the andesite line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands | Earth—the Mariana Trench—lies below sea level. Its average depth is , putting the total water volume at roughly . Due to the effects of plate tectonics, the Pacific Ocean is currently shrinking by roughly per year on three sides, roughly averaging a year. By contrast, the Atlantic Ocean is increasing in size. Along the Pacific Ocean's irregular western margins lie many seas, the largest of which are the Celebes Sea, Coral Sea, East China Sea (East Sea), Philippine Sea, Sea of Japan, South China Sea (South Sea), Sulu Sea, Tasman Sea, and Yellow Sea (West Sea of Korea). The Indonesian Seaway (including the Strait of Malacca and Torres Strait) joins the Pacific and the Indian Ocean to the west, and Drake Passage and the Strait of Magellan link the Pacific with the Atlantic Ocean on the east. To the north, the Bering Strait connects the Pacific with the Arctic Ocean. As the Pacific straddles the 180th meridian, the West Pacific (or western Pacific, near Asia) is in the Eastern Hemisphere, while the East Pacific (or eastern Pacific, near the Americas) is in the Western Hemisphere. The Southern Pacific Ocean harbors the Southeast Indian Ridge crossing from south of Australia turning into the Pacific-Antarctic Ridge (north of the South Pole) and merges with another ridge (south of South America) to form the East Pacific Rise which also connects with another ridge (south of North America) which overlooks the Juan de Fuca Ridge. For most of Magellan's voyage from the Strait of Magellan to the Philippines, the explorer indeed found the ocean peaceful; however, the Pacific is not always peaceful. Many tropical storms batter the islands of the Pacific. The lands around the Pacific Rim are full of volcanoes and often affected by earthquakes. Tsunamis, caused by underwater earthquakes, have devastated many islands and in some cases destroyed entire towns.

There are about 25,000 islands in the Pacific Ocean. The islands entirely within the Pacific Ocean can be divided into three main groups known as Micronesia, Melanesia and Polynesia. Micronesia, which lies north of the equator and west of the International Date Line, includes the Mariana Islands in the northwest, the Caroline Islands in the center, the Marshall Islands to the east and the islands of Kiribati in the southeast. Melanesia, to the southwest, includes New Guinea, the world's second largest island after Greenland and by far the largest of the Pacific islands. The other main Melanesian groups from north to south are the Bismarck Archipelago, the Solomon Islands, Santa Cruz, Vanuatu, Fiji and New Caledonia. The largest area, Polynesia, stretching from Hawaii in the north to New Zealand in the south, also encompasses Tuvalu, Tokelau, Samoa, Tonga and the Kermadec Islands to the west, the Cook Islands, Society Islands and Austral Islands in the center, and the Marquesas Islands, Tuamotu, Mangareva Islands, and Easter Island to the east. Islands in the Pacific Ocean are of four basic types: continental islands, high islands, coral reefs and uplifted coral platforms. Continental islands lie outside the andesite line and include New Guinea, the islands of New Zealand, and the Philippines. Some of these islands are structurally associated with nearby continents. High islands are of volcanic origin, and many contain active volcanoes. Among these are Bougainville, Hawaii, and the Solomon Islands. The coral reefs of the South Pacific are low-lying structures that have built up on basaltic lava flows under the ocean's surface. One of the most dramatic is the Great Barrier Reef off northeastern Australia with chains of reef patches. A second island type formed of coral is the uplifted coral platform, which is usually slightly larger than the low coral islands. Examples include Banaba (formerly Ocean Island) and Makatea in the Tuamotu group of French Polynesia. Water characteristics The volume of the Pacific Ocean, representing about 50.1 percent of the world's oceanic water, has been estimated at some . Surface water temperatures in the Pacific can vary from , the freezing point of seawater, in the poleward areas to about near the equator. Salinity also varies latitudinally, reaching a maximum of 37 parts per thousand in the southeastern area. The water near the equator, which can have a salinity as low as 34 parts per thousand, is less salty than that found in the mid-latitudes because of abundant equatorial precipitation throughout the year. The lowest counts of less than 32 parts per thousand are found in the far north as less evaporation of seawater takes place in these frigid areas. The motion of Pacific waters is generally clockwise in the Northern Hemisphere (the North Pacific gyre) and counter-clockwise in the Southern Hemisphere. The North Equatorial Current, driven westward along latitude 15°N by the trade winds, turns north near the Philippines to become the warm Japan or Kuroshio Current. Turning eastward at about 45°N, the Kuroshio forks and some water moves northward as the Aleutian Current, while the rest turns southward to rejoin the North Equatorial Current. The Aleutian Current branches as it approaches North America and forms the base of a counter-clockwise circulation in the Bering Sea. Its southern arm becomes the chilled slow, south-flowing California Current. The South Equatorial Current, flowing west along the equator, swings southward east of New Guinea, turns east at about 50°S, and joins the main westerly circulation of the South Pacific, which includes the Earth-circling Antarctic Circumpolar Current. As it approaches the Chilean coast, the South Equatorial Current divides; one branch flows around Cape Horn and the other turns north to form the Peru or Humboldt Current. Climate The climate patterns of the Northern and Southern Hemispheres generally mirror each other. The trade winds in the southern and eastern Pacific are remarkably steady while conditions in the North Pacific are far more varied with, for example, cold winter temperatures on the east coast of Russia contrasting with the milder weather off British Columbia during the winter months due to the preferred flow of ocean currents. In the tropical and subtropical Pacific, the El Niño Southern Oscillation (ENSO) affects weather conditions. To determine the phase of ENSO, the most recent three-month sea surface temperature average for the area approximately to the southeast of Hawaii is computed, and if the region is more than above or below normal for that period, then an El Niño or La Niña is considered in progress. In the tropical western Pacific, the monsoon and the related wet season during the summer months contrast with dry winds in the winter which blow over the ocean from the Asian landmass. Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures is the greatest; however, each particular basin has its own seasonal patterns. On a worldwide scale, May is the least active month, while September is the most active month. November is the only month in which all the tropical cyclone basins are active. The Pacific hosts the two most active tropical cyclone basins, which are the northwestern Pacific and the eastern Pacific. Pacific hurricanes form south of Mexico, sometimes striking the western Mexican coast and occasionally the southwestern United States between June and October, while typhoons forming in the northwestern Pacific moving into southeast and east Asia from May to December. Tropical cyclones also form in the South Pacific basin, where they occasionally impact island nations. In the arctic, icing from October to May can present a hazard for shipping while persistent fog occurs from June to December. A climatological low in the Gulf of Alaska keeps the southern coast wet and mild during the winter months. The Westerlies and associated jet stream within the Mid-Latitudes can be particularly strong, especially in the Southern Hemisphere, due to the temperature difference between the tropics and Antarctica, which records the coldest temperature readings on the planet. In the Southern hemisphere, because of the stormy and cloudy conditions associated with extratropical cyclones riding the jet stream, it is usual to refer to the Westerlies as the Roaring Forties, Furious Fifties and Shrieking Sixties according to the varying degrees of latitude. Geology The ocean was first mapped by Abraham Ortelius; he called it Maris Pacifici following Ferdinand Magellan's description of it as "a pacific sea" during his circumnavigation from 1519 to 1522. To Magellan, it seemed much more calm (pacific) than the Atlantic. The andesite line is the most significant regional distinction in the Pacific. A petrologic boundary, it separates the deeper, mafic igneous rock of the Central Pacific Basin from the partially submerged continental areas of felsic igneous rock on its margins. The andesite line follows the western edge of the islands off California and passes south of the Aleutian arc, along the eastern edge of the Kamchatka Peninsula, the Kuril Islands, Japan, the Mariana Islands, the Solomon Islands, and New Zealand's North Island. The dissimilarity continues northeastward along the western edge of the Andes Cordillera along South America to Mexico, returning then to the islands off California. Indonesia, the Philippines, Japan, New Guinea, and New Zealand lie outside the andesite line. Within the closed loop of the andesite line are most of the deep troughs, submerged volcanic mountains, and oceanic volcanic islands that characterize the Pacific basin. Here basaltic lavas gently flow out of rifts to build huge dome-shaped volcanic mountains whose eroded summits form island arcs, chains, and clusters. Outside the andesite line, volcanism is of the explosive type, and the Pacific Ring of Fire is the world's foremost belt of explosive volcanism. The Ring of Fire is named after the several hundred active volcanoes that sit above the various subduction zones. The Pacific Ocean is the only ocean which is mostly bounded by subduction zones. Only the Antarctic and Australian coasts have no nearby subduction zones. Geological history The Pacific Ocean was born 750 million years ago at the breakup of Rodinia, although it is generally called the Panthalassa until the breakup of Pangea, about 200 million years ago. The oldest Pacific Ocean floor is only around 180 Ma old, |
to the British at the conclusion of the French and Indian War in 1763 and became part of the colony of Nova Scotia, and in 1769 the island became its own British colony. Prince Edward Island hosted the Charlottetown Conference in 1864 to discuss a union of the Maritime provinces; however, the conference became the first in a series of meetings which led to Canadian Confederation in 1867. Prince Edward Island initially balked at Confederation but, facing bankruptcy from the Land Question and construction of a railroad, joined as Canada's seventh province in 1873. According to Statistics Canada, the province of Prince Edward Island has 158,717 residents. The backbone of the island economy is farming; it produces 25% of Canada's potatoes. Other important industries include the fisheries, tourism, aerospace, bio-science, IT, and renewable energy. As Prince Edward Island is one of Canada's older settlements, its population still reflects some of the earliest settlers, with Canadien, Scottish, Irish, and English surnames being dominant. Prince Edward Island is located in the Gulf of St. Lawrence, about north of Halifax and east of Quebec City, and has a land area of . The main island is in size. It is the 104th-largest island in the world and Canada's 23rd-largest island. Etymology The island is known in the Mi'kmaq language of its historic indigenous occupants as Abegweit or Epekwitk, roughly translated as "land cradled in the waves". When the island was part of Acadia, originally settled by French colonists, its French name was Île Saint-Jean (St. John's Island). In French, the island is today called Île-du-Prince-Édouard. As a result of the early French colonial name, Scots immigrants knew the island in Scottish Gaelic as Eilean a' Phrionnsa (lit. "the Island of the Prince", the local form of the longer 'Eilean a' Phrionnsa Iomhair/Eideard') or Eilean Eòin for some Gaelic speakers in Nova Scotia, though not on PEI (literally, "John's Island" in reference to the island's former French name). The island was split from the British colony of Nova Scotia in 1769, and renamed in 1798 after Prince Edward, Duke of Kent and Strathearn (1767–1820), the fourth son of King George III and, in 1817, father of the future Queen Victoria. Thus, Prince Edward has been called "Father of the Canadian Crown". The following island landmarks are also named after the Duke of Kent: Prince Edward Battery, Victoria Park, Charlottetown Kent College, established in 1804 by Lieutenant Governor Edmund Fanning and his Legislative Council, the college would eventually become the University of Prince Edward Island Kent Street, Charlottetown West Kent Elementary School Kent Street, Georgetown Geography Prince Edward Island is located in the Gulf of St. Lawrence, west of Cape Breton Island, north of the Nova Scotia peninsula, and east of New Brunswick. Its southern shore bounds the Northumberland Strait. The island has two urban areas, and in total, is the most densely populated province in Canada. The larger urban area surrounds Charlottetown Harbour, situated centrally on the island's southern shore. It consists of the capital city Charlottetown, and suburban towns Cornwall and Stratford and a developing urban fringe. A much smaller urban area developed around Summerside Harbour, situated on the southern shore west of Charlottetown Harbour. This consists primarily of the city of Summerside. As with all natural harbours on the island, Charlottetown and Summerside harbours are created by rias. The coastline has a combination of long beaches, dunes, red sandstone cliffs, salt water marshes, and numerous bays and harbours. The beaches, dunes and sandstone cliffs consist of sedimentary rock and other material with a high iron concentration, which oxidises upon exposure to the air. The geological properties of a white silica sand found at Basin Head are unique in the province; the sand grains cause a scrubbing noise as they rub against each other when walked on, and have been called the "singing sands". Large dune fields on the north shore can be found on barrier islands at the entrances to various bays and harbours. The sand dunes at Greenwich are of particular significance. The shifting, parabolic dune system is home to a variety of birds and rare plants; it is also a site of significant archeological interest. Climate The climate of the island is a maritime climate considered to be moderate and strongly influenced by the surrounding seas. As such, it is milder than inland locations owing to the warm waters from the Gulf of St. Lawrence. The climate is characterized by changeable weather throughout the year; it has some of the most variable day-to-day weather in Canada, in which specific weather conditions seldom last for long. During July and August, the average daytime high in PEI is ; however, the temperature can sometimes exceed during these months. In the winter months of January and February, the average daytime high is . The Island receives an average yearly rainfall of and an average yearly snowfall of . Winters are moderately cold and long but are milder than inland locations, with clashes of cold Arctic air and milder Atlantic air causing frequent temperature swings. The climate is considered to be more humid continental climate than oceanic since the Gulf of St. Lawrence freezes over, thus eliminating any moderation. The mean temperature is in January. During the winter months, the island usually has many storms (which may produce rain as well as snow) and blizzards since during this time, storms originating from the North Atlantic or the Gulf of Mexico frequently pass through. Springtime temperatures typically remain cool until the sea ice has melted, usually in late April or early May. Summers are moderately warm, but rarely uncomfortable, with the daily maximum temperature only occasionally reaching as high as . Autumn is a pleasant season, as the moderating Gulf waters delay the onset of frost, although storm activity increases compared to the summer. There is ample precipitation throughout the year, although it is heaviest in the late autumn, early winter and mid spring. The following climate chart depicts the average conditions of Charlottetown, as an example of the small province's climate. Geology Between 250 and 300 million years ago, freshwater streams flowing from ancient mountains brought silt, sand and gravel into what is now the Gulf of St. Lawrence. These sediments accumulated to form a sedimentary basin, and make up the island's bedrock. When the Pleistocene glaciers receded about 15,000 years ago, glacial debris such as till were left behind to cover most of the area that would become the island. This area was connected to the mainland by a strip of land, but when ocean levels rose as the glaciers melted, this land strip was flooded, forming the island. As the land rebounded from the weight of the ice, the island rose up to elevate it farther from the surrounding water. Most of the bedrock in Prince Edward Island is composed of red sandstone, part of the Permian age Pictou Group. Although commercial deposits of minerals have not been found, exploration in the 1940s for natural gas beneath the northeastern end of the province resulted in the discovery of an undisclosed quantity of gas. The Island was reported by government to have only 0.08 tcf of "technically recoverable" natural gas. Twenty exploration wells for hydrocarbon resources have been drilled on Prince Edward Island and offshore. The first reported well was Hillsborough No.#1, drilled in Charlottetown Harbour in 1944 (the world's first offshore well), and the most recent was New Harmony No.#1 in 2007. Since the resurgence of exploration in the mid-1990s, all wells that have shown promising gas deposits have been stimulated through hydraulic fracture or "fracking". All oil and natural gas exploration and exploitation activities on the Island are governed by the Oil and Natural Gas Act R.S.P.E.I. 1988, Cap. 0-5 and its associated regulations and orders. Water supply The Province of Prince Edward Island is completely dependent on groundwater for its source of drinking water, with approximately 305 high capacity wells in use as of December 2018. As groundwater flows through an aquifer, it is naturally filtered. The water for the city of Charlottetown is extracted from thirteen wells in three wellfields and distributed to customers. The water removed is replenished by precipitation. Infrastructure in Charlottetown that was installed in 1888 is still in existence. With the age of the system in the older part of Charlottetown, concern has been raised regarding lead pipes. The Utility has been working with its residents on a lead-replacement program. A plebiscite in 1967 was held in Charlottetown over fluoridation, and residents voted in favour. Under provincial legislation, the Utility is required to report to its residents on an annual basis. It is also required to do regular sampling of the water and an overview is included in each annual report. The Winter River watershed provides about 92 per cent of the water supply for the city of Charlottetown, which had difficulty in each of 2011, 2012 and 2013 with its supply, until water meters were installed. Government tabled a discussion paper on the proposed Water Act for the province on July 8, 2015. The use of groundwater came under scrutiny as the potato industry, which accounts for $1 billion every year and 50% of farm receipts, has pressed the government to lift a moratorium on high-capacity water wells for irrigation. The release of the discussion paper was to set off a consultation process in the autumn of 2015. Detailed information about the quality of drinking water in PEI communities and watersheds can be found on the provincial government's official website. It provides a summary of the ongoing testing of drinking water done by the Prince Edward Island Analytical Laboratories. Average drinking-water quality results are available, and information on the following parameters are provided: alkalinity; cadmium; calcium; chloride; chromium; iron; magnesium; manganese; nickel; nitrate; pH; phosphorus; potassium; sodium; and sulfate, as well as the presence of pesticides. Water-testing services are provided for a variety of clients through the PEI Analytical Laboratories which assesses according to the recommendations of the Guidelines for Canadian Drinking Water Quality published by Health Canada. Flora and fauna Prince Edward Island used to have native moose, bear, caribou, wolf, and other larger species. Due to hunting and habitat disruption these species are no longer found on the island. Some species common to P.E.I. are red foxes, coyote, blue jays, and robins. Skunks and raccoons are common non-native species. Species at risk in P.E.I. include piping plovers, american eel, bobolinks, little brown bat, and beach pinweed. Some species are unique to the province. In 2008, a new ascomycete species, Jahnula apiospora (Jahnulales, Dothideomycetes), was collected from submerged wood in a freshwater creek on Prince Edward Island. North Atlantic right whales, one of the rarest whale species, were once thought to be rare visitors into St. Lawrence regions until 1994, have been showing dramatic increases (annual concentrations were discovered off Percé in 1995 and gradual increases across the regions since in 1998), and since in 2014, notable numbers of whales have been recorded around Cape Breton to Prince Edward Island as 35 to 40 whales were seen in these areas in 2015. History Since before the influx of Europeans, the Mi'kmaq First Nations have inhabited Prince Edward Island as part of the region of Mi'kma'ki. They named the Island Epekwitk, meaning 'cradled on the waves'; Europeans represented the pronunciation as Abegweit. Another name is Minegoo. The Mi'kmaq's legend is that the island was formed by the Great Spirit placing on the Blue Waters some dark red crescent-shaped clay. There are two Mi'kmaq First Nation communities on Epekwitk today.

French colony In 1534, Jacques Cartier was the first European to see the island. In 1604, the Kingdom of France laid claim to the lands of the Maritimes under the discovery doctrine, including Prince Edward Island, establishing the French colony of Acadia. The island was named Île Saint-Jean (St. John's Island) by the French. The Mi'kmaq never recognized the claim but welcomed the French as trading partners and allies. During the 18th century, the French were engaged in a series of conflicts with the Kingdom of Great Britain and its colonies. Several battles between the two belligerents occurred on Prince Edward Island during this period. Following the British capture of Louisbourg during the War of the Austrian Succession, New Englanders launched an attack on Île Saint-Jean (Prince Edward Island); with a British detachment landed at Port-la-Joye. The island's capital had a garrison of 20 French soldiers under the command of Joseph du Pont Duvivier. The troops fled the settlement, and the New Englanders burned the settlement to the ground. Duvivier and the twenty men retreated up the Northeast River (Hillsborough River), pursued by the New Englanders until the French troops were reinforced with the arrival of the Acadian militia and the Mi'kmaq. The French troops and their allies were able to drive the New Englanders to their boats. Nine New Englanders were killed, wounded or made prisoner. The New Englanders took six Acadian hostages, who would be executed if the Acadians or Mi'kmaq rebelled against New England control. The New England troops left for Louisbourg. Duvivier and his 20 troops left for Quebec. After the fall of Louisbourg, the resident French population of Île Royale were deported to France, with the remaining Acadians of Île Saint-Jean living under the threat of deportation for the remainder of the war. New Englanders had a force of 200 soldiers stationed at Port-La-Joye, as well as two warships boarding supplies for its journey of Louisbourg. To regain Acadia, Ramezay was sent from Quebec to the region to join forces with the Duc d'Anville expedition. Upon arriving at Chignecto, he sent Boishebert to Île Saint-Jean to ascertain the size of the New England force. After Boishebert returned, Ramezay sent Joseph-Michel Legardeur de Croisille et de Montesson along with over 500 men, 200 of whom were Mi'kmaq, to Port-La-Joye. In July 1746, the battle happened near York River. Montesson and his troops killed forty New Englanders and captured the rest. Montesson was commended for having distinguished himself in his first independent command. Hostilities between the British and French was ended in 1748 with the Treaty of Aix-la-Chapelle in 1748. Roughly one thousand Acadians lived on the island prior to the Acadian Exodus from Nova Scotia. The population grew to nearly 5,000 the late 1740s and early 1750s, as Acadians from Nova Scotia fled to the island during the Acadian Exodus, and the subsequent British-ordered expulsions beginning in 1755. Hostilities between British and French colonial forces resumed in 1754, although formal declarations of war were not issued until 1756. After French forces were defeated at the siege of Louisbourg, the British performed a military campaign on Ile Saint-Jean to secure the island. The campaign was led by Colonel Andrew Rollo under orders from General Jeffery Amherst. The following campaigns saw the deportation of most Acadians from the island. Many Acadians died in the expulsion en route to France; on December 13, 1758, the transport ship Duke William sank and 364 died. A day earlier the Violet sank and 280 died; several days later sank with 213 on board. The French formally ceded the island, and most of New France to the British in the Treaty of Paris of 1763. British colony Initially named St. John's Island by the British, the island was administered as part of the colony of Nova Scotia, until it was split into a separate colony in 1769. In the mid-1760s, a survey team led by Samuel Holland divided the Island into 67 lots. On July 1, 1767, these properties were allocated to supporters of King George III by means of a lottery. Ownership of the land remained in the hands of landlords in England, angering Island settlers who were unable to gain title to land on which they worked and lived. Significant rent charges (to absentee landlords) created further anger. The land had been given to the absentee landlords with a number of conditions attached regarding upkeep and settlement terms; many of these conditions were not satisfied. Islanders spent decades trying to convince the Crown to confiscate the lots, however the descendants of the original owners were generally well connected to the British government and refused to give up the land. After the island was detached from Nova Scotia to become a separate colony, Walter Patterson was appointed the first British governor of St. John's Island in 1769. Assuming the office in 1770, he had a controversial career during which land title disputes and factional conflict slowed the initial attempts to populate and develop the island under a feudal system. In an attempt to attract settlers from Ireland, in one of his first acts (1770) Patterson led the island's colonial assembly to rename the island "New Ireland", but the British Government promptly vetoed this as it exceeded the authority vested in the colonial government; only the Privy Council in London could change the name of a colony. During the American Revolutionary War Charlottetown was raided in 1775 by a pair of American-employed privateers. Two armed schooners, Franklin and Hancock, from Beverly, Massachusetts, made prisoner of the attorney-general at Charlottetown, on advice given them by some Pictou residents after they had taken eight fishing vessels in the Gut of Canso. During and after the American Revolutionary War, from 1776 to 1783, the colony's efforts to attract exiled Loyalist refugees from the rebellious American colonies met with some success. Walter Patterson's brother, John Patterson, one of the original grantees of land on the island, was a temporarily exiled Loyalist and led efforts to persuade others to come. Governor Patterson dismissal in 1787, and his recall to London in 1789 dampened his brother's efforts, leading John to focus on his interests in the United States. Edmund Fanning, also a Loyalist exiled by the Revolution, took over as the second governor, serving until 1804. His tenure was more successful than Patterson's. A large influx of Scottish Highlanders in the late 1700s also resulted in St. John's Island having the highest proportion of Scottish immigrants in Canada. This led to a higher proportion of Scottish Gaelic speakers and thriving culture surviving on the island than in Scotland itself, as the settlers could more easily avoid English influence overseas. On 29 November 1798, during Fanning's administration, the British government granted approval to change the colony's name from St. John's Island to Prince Edward Island to distinguish it from areas with similar names in what is now Atlantic Canada, such as the cities of Saint John in New Brunswick and St. John's in Newfoundland. The colony's new name honoured the fourth son of King George III, Prince Edward Augustus, the Duke of Kent (1767–1820), who subsequently led the British military forces on the continent as Commander-in-Chief, North America (1799–1800), with his headquarters in Halifax. In 1853, the Island government passed the Land Purchase Act which empowered them to purchase lands from those owners who were willing to sell, and then resell the land to settlers for low prices. This scheme collapsed when the Island ran short of money to continue with the purchases. Many of these lands also were fertile, and were some of the key factors to sustaining Prince Edward Island's economy. Confederation In September 1864, Prince Edward Island hosted the Charlottetown Conference, which was the first meeting in the process leading to the Quebec Resolutions and the creation of Canada in 1867. Prince Edward Island did not find the terms of union favourable and balked at joining in 1867, choosing to remain a colony of the United Kingdom. In the late 1860s, the colony examined various options, including the possibility of becoming a discrete dominion unto itself, as well as entertaining delegations from the United States, who were interested in Prince Edward Island joining the United States. In 1871, the colony began construction of the Prince Edward Island Railway (PEIR) and, frustrated by Great Britain's Colonial Office, began negotiations with the United States. In 1873, Canadian Prime Minister John A. Macdonald, anxious to thwart American expansionism and facing the distraction of the Pacific Scandal, negotiated for Prince Edward Island to join Canada. The Dominion Government of Canada assumed the colony's extensive railway debts and agreed to finance a buy-out of the last of the colony's absentee landlords to free the island of leasehold tenure and from any new immigrants entering the island (accomplished through the passage of the Land Purchase Act, 1875). Prince Edward Island entered Confederation on July 1, 1873. As a result of having hosted the inaugural meeting of Confederation, the Charlottetown Conference, Prince Edward Island presents itself as the "Birthplace of Confederation" and this is commemorated through several buildings, a ferry vessel, and the Confederation Bridge (constructed 1993 to 1997). The most prominent building in the province honouring this event is the Confederation Centre of the Arts, presented as a gift to Prince Edward Islanders by the 10 provincial governments and the Federal Government upon the centenary of the Charlottetown Conference, where it stands in Charlottetown as a national monument to the "Fathers of Confederation". The centre is one of the 22 National Historic Sites of Canada located in Prince Edward Island. Demographics Ethnic origins According to the 2016 Canadian Census of the 139,690 people who self-identified with an ethnic origin, 98,615 were of European origins and 85,145 chose British Isles Origins. The largest ethnic group consists of people of Scottish descent (36%), followed by English (29%), Irish (28%), French (21%), German (5%), and Dutch (3%) descent. Prince Edward Island's population is largely white; there are few visible minorities. Chinese Canadians are the largest visible minority group of Prince Edward Island, comprising 1.3% of the province's population. Almost half of respondents identified their ethnicity as "Canadian". Source: Statistics Canada Language The Canada 2016 Census showed a population of 142,910. Of the 140,020 singular responses to the census question concerning mother tongue, the most commonly reported languages were as follows: In addition, there were 460 responses of both English and a "non-official language"; 30 of both French and a "non-official language"; 485 of both English and French; and 20 of English, French, and a "non-official language". (Figures shown are for the number of single language responses and the percentage of total single-language responses.) Religion Traditionally, the population has been evenly divided between Catholic and Protestant affiliations. The 2001 census indicated number of adherents for the Roman Catholic Church with 63,240 (47%) and various Protestant churches with 57,805 (43%). This included the United Church of Canada with 26,570 (20%); the Presbyterian Church with 7,885 (6%) and the Anglican Church of Canada with 6,525 (5%); those with no religion were among the lowest of the provinces with 8,705 (6.5%). If one considers that the founders of the United Church of Canada were largely Presbyterians in Prince Edward Island, the Island has one of the highest percentages of Presbyterians in the country. Since 2016 there are two Amish settlements on Prince Edward Island. The Island also has one of the largest number of Free Church of Scotland buildings in Canada. Economy The provincial economy is dominated by the seasonal industries of agriculture, tourism, and the fishery. The island also has tourists who visit year-round. with tourists enjoying a variety of leisure activities, including the beaches, various golf courses, eco-tourism adventures, touring the countryside, and varied cultural events in local communities around the island. The economy of most rural communities on the island is based on small-scale agriculture. Industrial farming has increased as businesses buy and consolidate older farm properties. The province is limited in terms of heavy industry and manufacturing, though Cavendish Farms runs extensive food manufacturing operations on PEI. Agriculture remains the dominant industry in the provincial economy, as it has since colonial times. In 2015, agriculture and agri-food manufacturing was responsible for 7.6% of the province's GDP. The Island has a total land area of with approximately cleared for agricultural use. In 2016, the Census of Agriculture counted 1,353 farms on the Island, which is a 9.5% decrease from the previous census (2011). During the 20th century, potatoes replaced mixed farming as the leading cash crop, accounting for one-third of provincial farm income. The number of acres under potato production in 2010 was 88,000, while soy accounted for 55,000. There are approximately 330 potato growers on PEI, with the grand majority of these being family farms, often with multiple generations working together. The province currently accounts for a third of Canada's total potato production, producing approximately annually. Comparatively, the state of Idaho produces approximately annually, with a population approximately 9.5 times greater. The province is a major producer of seed potatoes, exporting to more than twenty countries around the world. An estimated total of 70% of the land is cultivated and 25% of all potatoes grown in Canada originate from P.E.I. The processing of frozen fried potatoes, green vegetables, and berries is a leading business activity. As a legacy of the island's colonial history, the provincial government enforces extremely strict rules for non-resident land ownership, especially since the PEI Lands Protection Act of 1982. Residents and corporations are limited to maximum holdings of 400 and 1,200 hectares respectively. There are also restrictions on non-resident ownership of shorelines. Many of the province's coastal communities rely upon shellfish harvesting, particularly lobster fishing as well as oyster fishing and mussel farming. The island's economy has grown significantly over the last decade in key areas of innovation. Aerospace, bioscience, information and communications technology, and renewable energy have been a focus for growth and diversification. Aerospace alone now accounts for over 25% of the province's international exports and is the island's fourth largest industry at $355 million in annual sales. The bioscience industry employs over 1,300 people and generates over $150 million in sales. The sale of carbonated beverages such as beer and soft drinks in non-refillable containers, such as aluminum cans or plastic bottles, was banned in 1976 as an environmental measure in response to public concerns over litter. Beer and soft drink companies opted to use refillable glass bottles for their products which were redeemable at stores and bottle depots. Though often environmental and economic agendas may be at odds, the ‘ban the can’ legislation, along with being environmentally driven, was also economically motivated as it protected jobs. Seaman's Beverages, a bottling company and carbonated beverage manufacturer, was established in 1939 and a major employer in Charlottetown, Prince Edward Island. Making it illegal to retail cans led to a bigger share of the carbonated beverage market for Seamans. Seamans Beverages was eventually acquired by Pepsi Bottling Group Inc in 2002 prior to the lifting of the legislation. The introduction of recycling programs for cans and plastic bottles in neighbouring provinces in recent years (also using a redemption system) has seen the provincial government introduce legislation to reverse this ban with the restriction lifted on May 3, 2008. Prior to harmonization in 2013, Prince Edward Island had one of Canada's highest provincial retail sales tax rates at 10%. On April 1, 2013, the provincial tax was harmonized with the federal Goods and Services Tax, and became known as the Harmonized Sales Tax. The 15% tax is applied to almost all goods and services except some clothing, food and home heating fuel. This rate is the same as the neighbouring Atlantic provinces. The provincial government provides consumer protection in the form of regulation for certain items, ranging from apartment rent increases to petroleum products including gas, diesel, propane and heating oil. These are regulated through the Prince Edward Island Regulatory and Appeals Commission (IRAC). IRAC is authorized to limit the number of companies who are permitted to sell petroleum products. , the median family income on Prince Edward Island is $76,607/year. The minimum wage is $12.85/hour .

may be digitally signed by a third-party user to attest to the association between someone (actually a user name) and the key. There are several levels of confidence that can be included in such signatures. Although many programs read and write this information, few (if any) include this level of certification when calculating whether to trust a key. The web of trust protocol was first described by Phil Zimmermann in 1992, in the manual for PGP version 2.0: The web of trust mechanism has advantages over a centrally managed public key infrastructure scheme such as that used by S/MIME but has not been universally used. Users have to be willing to accept certificates and check their validity manually or have to simply accept them. No satisfactory solution has been found for the underlying problem. Certificates In the (more recent) OpenPGP specification, trust signatures can be used to support creation of certificate authorities. A trust signature indicates both that the key belongs to its claimed owner and that the owner of the key is trustworthy to sign other keys at one level below their own. A level 0 signature is comparable to a web of trust signature since only the validity of the key is certified. A level 1 signature is similar to the trust one has in a certificate authority because a key signed to level 1 is able to issue an unlimited number of level 0 signatures. A level 2 signature is highly analogous to the trust assumption users must rely on whenever they use the default certificate authority list (like those included in web browsers); it allows the owner of the key to make other keys certificate authorities. PGP versions have always included a way to cancel ('revoke') public key certificates. A lost or compromised private key will require this if communication security is to be retained by that user. This is, more or less, equivalent to the certificate revocation lists of centralised PKI schemes. Recent PGP versions have also supported certificate expiration dates. The problem of correctly identifying a public key as belonging to a particular user is not unique to PGP. All public key/private key cryptosystems have the same problem, even if in slightly different guises, and no fully satisfactory solution is known. PGP's original scheme at least leaves the decision as to whether or not to use its endorsement/vetting system to the user, while most other PKI schemes do not, requiring instead that every certificate attested to by a central certificate authority be accepted as correct. Security quality To the best of publicly available information, there is no known method which will allow a person or group to break PGP encryption by cryptographic, or computational means. Indeed, in 1995, cryptographer Bruce Schneier characterized an early version as being "the closest you're likely to get to military-grade encryption." Early versions of PGP have been found to have theoretical vulnerabilities and so current versions are recommended. In addition to protecting data in transit over a network, PGP encryption can also be used to protect data in long-term data storage such as disk files. These long-term storage options are also known as data at rest, i.e. data stored, not in transit. The cryptographic security of PGP encryption depends on the assumption that the algorithms used are unbreakable by direct cryptanalysis with current equipment and techniques. In the original version, the RSA algorithm was used to encrypt session keys. RSA's security depends upon the one-way function nature of mathematical integer factoring. Similarly, the symmetric key algorithm used in PGP version 2 was IDEA, which might at some point in the future be found to have previously undetected cryptanalytic flaws. Specific instances of current PGP or IDEA insecurities (if they exist) are not publicly known. As current versions of PGP have added additional encryption algorithms, their cryptographic vulnerability varies with the algorithm used. However, none of the algorithms in current use are publicly known to have cryptanalytic weaknesses. New versions of PGP are released periodically and vulnerabilities fixed by developers as they come to light. Any agency wanting to read PGP messages would probably use easier means than standard cryptanalysis, e.g. rubber-hose cryptanalysis or black-bag cryptanalysis (e.g. installing some form of trojan horse or keystroke logging software/hardware on the target computer to capture encrypted keyrings and their passwords). The FBI has already used this attack against PGP in its investigations. However, any such vulnerabilities apply not just to PGP but to any conventional encryption software. In 2003, an incident involving seized Psion PDAs belonging to members of the Red Brigade indicated that neither the Italian police nor the FBI were able to decrypt PGP-encrypted files stored on them. A second incident in December 2006, (see In re Boucher), involving US customs agents who seized a laptop PC that allegedly contained child pornography, indicates that US government agencies find it "nearly impossible" to access PGP-encrypted files. Additionally, a magistrate judge ruling on the case in November 2007 has stated that forcing the suspect to reveal his PGP passphrase would violate his Fifth Amendment rights i.e. a suspect's constitutional right not to incriminate himself. The Fifth Amendment issue was opened again as the government appealed the case, after which a federal district judge ordered the defendant to provide the key. Evidence suggests that , British police investigators are unable to break PGP, so instead have resorted to using RIPA legislation to demand the passwords/keys. In November 2009 a British citizen was convicted under RIPA legislation and jailed for nine months for refusing to provide police investigators with encryption keys to PGP-encrypted files. PGP as a cryptosystem has been criticized for complexity of the standard, implementation and very low usability of the user interface including by recognized figures in cryptography research. It uses an ineffective serialization format for storage of both keys and encrypted data, which resulted in signature-spamming attacks on public keys of prominent developers of GNU Privacy Guard. Backwards compatibility of the OpenPGP standard results in usage of relatively weak default choices of cryptographic primitives (CAST5 cipher, CFB mode, S2K password hashing). The standard has been also criticized for leaking metadata, usage of long-term keys and lack of forward secrecy. Popular end-user implementations have suffered from various signature-striping, cipher downgrade and metadata leakage vulnerabilities which have been attributed to the complexity of the standard. History Early history Phil Zimmermann created the first version of PGP encryption in 1991. The name, "Pretty Good Privacy" was inspired by the name of a grocery store, "Ralph's Pretty Good Grocery", featured in radio host Garrison Keillor's fictional town, Lake Wobegon. This first version included a symmetric-key algorithm that Zimmermann had designed himself, named BassOmatic after a Saturday Night Live sketch. Zimmermann had been a long-time anti-nuclear activist, and created PGP encryption so that similarly inclined people might securely use BBSs and securely store messages and files. No license fee was required for its non-commercial use, and the complete source code was included with all copies. In a posting of June 5, 2001, entitled "PGP Marks 10th Anniversary", Zimmermann describes the circumstances surrounding his release of PGP: PGP found its way onto the Internet and rapidly acquired a considerable following around the world. Users and supporters included dissidents in totalitarian countries (some affecting letters to Zimmermann have been published, some of which have been included in testimony before the US Congress), civil libertarians in other parts of the world (see Zimmermann's published testimony in various hearings), and the 'free communications' activists who called themselves cypherpunks (who provided both publicity and distribution); decades later, CryptoParty activists did much the same via Twitter. Criminal investigation Shortly after its release, PGP encryption found its way outside the United States, and in February 1993 Zimmermann became the formal target of a criminal investigation by the US Government for "munitions export without a license". At the time, cryptosystems using keys larger than 40 bits were considered munitions within the definition of the US export regulations; PGP has never used keys smaller than 128 bits, so it qualified at that time. Penalties for violation, if found guilty, were substantial. After several years, the investigation of Zimmermann was closed without filing criminal charges against him or anyone else. Zimmermann challenged these regulations in an imaginative way. He published the entire source code of PGP in a hardback book, via MIT Press, which was distributed and sold widely. Anybody wishing to build their own copy of PGP could cut off the covers, separate the pages, and scan them using an OCR program (or conceivably enter it as a type-in program if OCR software was not available), creating a set of source code text files. One could then build the application using the freely available GNU Compiler Collection. PGP would thus be available anywhere in the world. The claimed principle was simple: export of munitions—guns, bombs, planes, and software—was (and remains) restricted; but the export of books is protected by the First Amendment. The question was never tested in court with respect to PGP. In cases addressing other encryption software, however, two federal appeals courts have established the rule that cryptographic software source code is speech protected by the First Amendment (the Ninth Circuit Court of Appeals in the Bernstein case and the Sixth Circuit Court of Appeals in the Junger case). US export regulations regarding cryptography remain in force, but were liberalized substantially throughout the late 1990s. Since 2000, compliance with the regulations is also much easier. PGP encryption no longer meets the definition of a non-exportable weapon, and can be exported internationally except to seven specific countries and a list of named groups and individuals (with whom substantially all US trade is prohibited under various US export controls). PGP 3 and founding of PGP Inc. During this turmoil, Zimmermann's team worked on a new version of PGP encryption called PGP 3. This new version was to have considerable security improvements, including a new certificate structure that fixed small security flaws in the PGP 2.x certificates as well as permitting a certificate to include separate keys for signing and encryption. Furthermore, the experience with patent and export problems led them to eschew patents entirely. PGP 3 introduced the use of the CAST-128 (a.k.a. CAST5) symmetric key algorithm, and the DSA and ElGamal asymmetric key algorithms, all of which were unencumbered by patents. After the Federal criminal investigation ended in 1996, Zimmermann and his team started a company to produce new versions of PGP encryption. They merged with Viacrypt (to whom Zimmermann had sold commercial rights and who had licensed RSA directly from RSADSI), which then changed its name to PGP Incorporated. The newly combined Viacrypt/PGP team started work on new versions of PGP encryption based on the PGP 3 system. | NAI stopped releasing source code. In early 2001, Zimmermann left NAI. He served as Chief Cryptographer for Hush Communications, who provide an OpenPGP-based e-mail service, Hushmail. He has also worked with Veridis and other companies. In October 2001, NAI announced that its PGP assets were for sale and that it was suspending further development of PGP encryption. The only remaining asset kept was the PGP E-Business Server (the original PGP Commandline version). In February 2002, NAI canceled all support for PGP products, with the exception of the renamed commandline product. NAI (formerly McAfee, then Intel Security, and now McAfee again) continued to sell and support the product under the name McAfee E-Business Server until 2013. PGP Corporation and Symantec In August 2002, several ex-PGP team members formed a new company, PGP Corporation, and bought the PGP assets (except for the command line version) from NAI. The new company was funded by Rob Theis of Doll Capital Management (DCM) and Terry Garnett of Venrock Associates. PGP Corporation supported existing PGP users and honored NAI's support contracts. Zimmermann served as a special advisor and consultant to PGP Corporation while continuing to run his own consulting company. In 2003, PGP Corporation created a new server-based product called PGP Universal. In mid-2004, PGP Corporation shipped its own command line version called PGP Command Line, which integrated with the other PGP Encryption Platform applications. In 2005, PGP Corporation made its first acquisition: the German software company Glück & Kanja Technology AG, which became PGP Deutschland AG. In 2010, PGP Corporation acquired Hamburg-based certificate authority TC TrustCenter and its parent company, ChosenSecurity, to form its PGP TrustCenter division. After the 2002 purchase of NAI's PGP assets, PGP Corporation offered worldwide PGP technical support from its offices in Draper, Utah; Offenbach, Germany; and Tokyo, Japan. On April 29, 2010, Symantec Corp. announced that it would acquire PGP for $300 million with the intent of integrating it into its Enterprise Security Group. This acquisition was finalized and announced to the public on June 7, 2010. The source code of PGP Desktop 10 is available for peer review. Also in 2010, Intel Corporation acquired McAfee. In 2013, the McAfee E-Business Server was transferred to Software Diversified Services, which now sells, supports, and develops it under the name SDS E-Business Server. For the enterprise, Townsend Security currently offers a commercial version of PGP for the IBM i and IBM z mainframe platforms. Townsend Security partnered with Network Associates in 2000 to create a compatible version of PGP for the IBM i platform. Townsend Security again ported PGP in 2008, this time to the IBM z mainframe. This version of PGP relies on a free z/OS encryption facility, which utilizes hardware acceleration. Software Diversified Services also offers a commercial version of PGP (SDS E-Business Server) for the IBM z mainframe. In May 2018, a bug named EFAIL was discovered in certain implementations of PGP which from 2003 could reveal the plaintext contents of emails encrypted with it. The chosen mitigation for this vulnerability in PGP Desktop is to mandate the use SEIP protected packets in the ciphertext, which can lead to old emails or other encrypted objects to be no longer decryptable after upgrading to the software version that has the mitigation. PGP Corporation encryption applications This section describes commercial programs available from PGP Corporation. For information on other programs compatible with the OpenPGP specification, see External links below. While originally used primarily for encrypting the contents of e-mail messages and attachments from a desktop client, PGP products have been diversified since 2002 into a set of encryption applications that can be managed by an optional central policy server. PGP encryption applications include e-mails and attachments, digital signatures, laptop full disk encryption, file and folder security, protection for IM sessions, batch file transfer encryption, and protection for files and folders stored on network servers and, more recently, encrypted or signed HTTP request/responses by means of a client-side (Enigform) and a server-side (mod openpgp) module. There is also a WordPress plugin available, called wp-enigform-authentication, that takes advantage of the session management features of Enigform with mod_openpgp. The PGP Desktop 9.x family includes PGP Desktop Email, PGP Whole Disk Encryption, and PGP NetShare. Additionally, a number of Desktop bundles are also available. Depending on the application, the products feature desktop e-mail, digital signatures, IM security, whole disk encryption, file, and folder security, encrypted self-extracting archives, and secure shredding of deleted files. Capabilities are licensed in different ways depending on the features required. The PGP Universal Server 2.x management console handles centralized deployment, security policy, policy enforcement, key management, and reporting. It is used for automated e-mail encryption in the gateway and manages PGP Desktop 9.x clients. In addition to its local keyserver, PGP Universal Server works with the PGP public keyserver—called the PGP Global Directory—to find recipient keys. It has the capability of delivering e-mail securely when no recipient key is found via a secure HTTPS browser session. With PGP Desktop 9.x managed by PGP Universal Server 2.x, first released in 2005, all PGP encryption applications are based on a new proxy-based architecture. These newer versions of PGP software eliminate the use of e-mail plug-ins and insulate the user from changes to other desktop applications. All desktop and server operations are now based on security policies and operate in an automated fashion. The PGP Universal server automates the creation, management, and expiration of keys, sharing these keys among all PGP encryption applications. The Symantec PGP platform has now undergone a rename. PGP Desktop is now known as Symantec Encryption Desktop (SED), and the PGP Universal Server is now known as Symantec Encryption Management Server (SEMS). The current shipping versions are Symantec Encryption Desktop 10.3.0 (Windows and macOS platforms) and Symantec Encryption Server 3.3.2. Also available are PGP Command-Line, which enables command line-based encryption and signing of information for storage, transfer, and backup, as well as the PGP Support Package for BlackBerry which enables RIM BlackBerry devices to enjoy sender-to-recipient messaging encryption. New versions of PGP applications use both OpenPGP and the S/MIME, allowing communications with any user of a NIST specified standard. OpenPGP Within PGP Inc., there was still concern surrounding patent issues. RSADSI was challenging the continuation of the Viacrypt RSA license to the newly merged firm. The company adopted an informal internal standard that they called "Unencumbered PGP" which would "use no algorithm with licensing difficulties". Because of PGP encryption's importance worldwide, many wanted to write their own software that would interoperate with PGP 5. Zimmermann became convinced that an open standard for PGP encryption was critical for them and for the cryptographic community as a whole. In July 1997, PGP Inc. proposed to the IETF that there be a standard called OpenPGP. They gave the IETF permission to use the name OpenPGP to describe this new standard as well as any program that supported the standard. The IETF accepted the proposal and started the OpenPGP Working Group. OpenPGP is on the Internet Standards Track and is under active development. Many e-mail clients provide OpenPGP-compliant email security as described in RFC 3156. The current specification is RFC 4880 (November 2007), the successor |
sword () of the Italian suits. In England, the French suits were eventually used, although the earliest packs circulating may have had Latin suits. This may account for why the English called the clovers "clubs" and the pikes "spades". In the late 14th century, Europeans changed the Mamluk court cards to represent European royalty and attendants. In a description from 1377, the earliest courts were originally a seated "king", an upper marshal that held his suit symbol up, and a lower marshal that held it down. The latter two correspond with the ober and unter cards found in German and Swiss playing cards. The Italians and Iberians replaced the / system with the "Knight" and "" or "" before 1390, perhaps to make the cards more visually distinguishable. In England, the lowest court card was called the "knave" which originally meant male child (compare German ), so in this context the character could represent the "prince", son to the king and queen; the meaning servant developed later. Queens appeared sporadically in packs as early as 1377, especially in Germany. Although the Germans abandoned the queen before the 1500s, the French permanently picked it up and placed it under the king. Packs of 56 cards containing in each suit a king, queen, knight, and knave (as in tarot) were once common in the 15th century. In 1628, the Mistery of Makers of Playing Cards of the City of London (now the Worshipful Company of Makers of Playing Cards) was incorporated under a royal charter by Charles I; the Company received livery status from the Court of Aldermen of the City of London in 1792. The Company still exists today, having expanded its member ranks to include "card makers... card collectors, dealers, bridge players, [and] magicians". During the mid 16th century, Portuguese traders introduced playing cards to Japan. The first indigenous Japanese deck was the named after the period. Later design changes Packs with corner and edge indices (i.e. the value of the card printed at the corner(s) of the card) enabled players to hold their cards close together in a fan with one hand (instead of the two hands previously used). The first such pack known with Latin suits was printed by Infirerra and dated 1693, but this feature was commonly used only from the end of the 18th century. The first American-manufactured (French) deck with this innovation was the Saladee's Patent, printed by Samuel Hart in 1864. In 1870, he and his cousins at Lawrence & Cohen followed up with the Squeezers, the first cards with indices that had a large diffusion. This was followed by the innovation of reversible court cards. This invention is attributed to a French card maker of Agen in 1745. But the French government, which controlled the design of playing cards, prohibited the printing of cards with this innovation. In central Europe (Trappola cards) and Italy (Tarocco Bolognese) the innovation was adopted during the second half of the 18th century. In Great Britain, the pack with reversible court cards was patented in 1799 by Edmund Ludlow and Ann Wilcox. The French pack with this design was printed around 1802 by Thomas Wheeler. Sharp corners wear out more quickly, and could possibly reveal the card's value, so they were replaced with rounded corners. Before the mid-19th century, British, American, and French players preferred blank backs. The need to hide wear and tear and to discourage writing on the back led cards to have designs, pictures, photos, or advertising on the reverse. The United States introduced the joker into the deck. It was devised for the game of euchre, which spread from Europe to America beginning shortly after the American Revolutionary War. In euchre, the highest trump card is the Jack of the trump suit, called the right bower (from the German Bauer); the second-highest trump, the left bower, is the jack of the suit of the same color as trumps. The joker was invented c. 1860 as a third trump, the imperial or best bower, which ranked higher than the other two bowers. The name of the card is believed to derive from juker, a variant name for euchre. The earliest reference to a joker functioning as a wild card dates to 1875 with a variation of poker. Research Columbia University's Rare Book and Manuscript Library holds the Albert Field Collection of Playing Cards, an archive of over 6,000 individual decks from over 50 countries and dating back to the 1550s. In 2018 the university digitized over 100 of its decks. Since 2017, Vanderbilt University has been home to the 1,000-volume George Clulow and United States Playing Card Co. Gaming Collection, which has been called one of the "most complete and scholarly collections [of books on cards and gaming] that has ever been gathered together". Modern deck formats Contemporary playing cards are grouped into three broad categories based on the suits they use: French, Latin, and Germanic. Latin suits are used in the closely related Spanish and Italian formats. The Swiss-German suits are distinct enough to merit their subcategory. Excluding jokers and tarot trumps, the French 52-card deck preserves the number of cards in the original Mamluk deck, while Latin and Germanic decks average fewer. Latin decks usually drop the higher-valued pip cards, while Germanic decks drop the lower-valued ones. Within suits, there are regional or national variations called "standard patterns." Because these patterns are in the public domain, this allows multiple card manufacturers to recreate them. Pattern differences are most easily found in the face cards but the number of cards per deck, the use of numeric indices, or even minor shape and arrangement differences of the pips can be used to distinguish them. Some patterns have been around for hundreds of years. Jokers are not part of any pattern as they are a relatively recent invention and lack any standardized appearance so each publisher usually puts its own trademarked illustration into their decks. The wide variation of jokers has turned them into collectible items. Any card that bore the stamp duty like the ace of spades in England, the ace of clubs in France or the ace of coins in Italy are also collectible as that is where the manufacturer's logo is usually placed. Typically, playing cards have indices printed in the upper-left and lower-right corners. While this design doesn't restrict which hand players hold their cards, some left-handed players may prefer to fan their cards in the opposite direction. Some designs exist with indices in all four corners. French-suited decks French decks come in a variety of patterns and deck sizes. The 52-card deck | also used for divination, although bespoke cards for this use are more common. Playing cards are typically palm-sized for convenient handling, and usually are sold together in a set as a deck of cards or pack of cards. The most common type of playing card is that found in the French-suited, standard 52-card pack, of which the most common design is the English pattern, followed by the Belgian-Genoese pattern. However, many countries use other, traditional types of playing card, including those that are German, Italian, Spanish and Swiss-suited. Tarot cards (also known locally as Tarocks or tarocchi) are an old genre of playing card that is still very popular in France, central and Eastern Europe and Italy. Asia, too, has regional cards such as the Japanese hanafuda. The reverse side of the card is often covered with a pattern that will make it difficult for players to look through the translucent material to read other people's cards. Playing cards are available in a wide variety of styles, as decks may be custom-produced for casinos and magicians (sometimes in the form of trick decks), made as promotional items, or intended as souvenirs, artistic works, educational tools, or branded accessories. Decks of cards or even single cards are also collected as a hobby or for monetary value. Cards may also be produced for trading card sets or collectible card games, which can comprise hundreds if not thousands of unique cards, or as supplements for board games. History China Playing cards may have been invented during the Tang dynasty around the 9th century AD as a result of the usage of woodblock printing technology. The earliest known text containing a possible reference to card games is a 9th-century text known as the Collection of Miscellanea at Duyang, written by Tang dynasty writer Su E. It describes Princess Tongchang, daughter of Emperor Yizong of Tang, playing the "leaf game" in 868 with members of the Wei clan, the family of the princess's husband. The first known book on the "leaf" game was called the Yezi Gexi and allegedly written by a Tang woman. It received commentary by writers of subsequent dynasties. The Song dynasty (960–1279) scholar Ouyang Xiu (1007–1072) asserts that the "leaf" game existed at least since the mid-Tang dynasty and associated its invention with the development of printed sheets as a writing medium. However, Ouyang also claims that the "leaves" were pages of a book used in a board game played with dice, and that the rules of the game were lost by 1067. Other games revolving around alcoholic drinking involved using playing cards of a sort from the Tang dynasty onward. However, these cards did not contain suits or numbers. Instead, they were printed with instructions or forfeits for whomever drew them. The earliest dated instance of a game involving cards occurred on 17 July 1294 when "Yan Sengzhu and Zheng Pig-Dog were caught playing cards [zhi pai] and that wood blocks for printing them had been impounded, together with nine of the actual cards." William Henry Wilkinson suggests that the first cards may have been actual paper currency which doubled as both the tools of gaming and the stakes being played for, similar to trading card games. Using paper money was inconvenient and risky so they were substituted by play money known as "money cards". One of the earliest games in which we know the rules is madiao, a trick-taking game, which dates to the Ming Dynasty (1368–1644). 15th-century scholar Lu Rong described it is as being played with 38 "money cards" divided into four suits: 9 in coins, 9 in strings of coins (which may have been misinterpreted as sticks from crude drawings), 9 in myriads (of coins or of strings), and 11 in tens of myriads (a myriad is 10,000). The two latter suits had Water Margin characters instead of pips on them with Chinese to mark their rank and suit. The suit of coins is in reverse order with 9 of coins being the lowest going up to 1 of coins as the high card. Persia and Arabia Despite the wide variety of patterns, the suits show a uniformity of structure. Every suit contains twelve cards with the top two usually being the court cards of king and vizier and the bottom ten being pip cards. Half the suits use reverse ranking for their pip cards. There are many motifs for the suit pips but some include coins, clubs, jugs, and swords which resemble later Mamluk and Latin suits. Michael Dummett speculated that Mamluk cards may have descended from an earlier deck which consisted of 48 cards divided into four suits each with ten pip cards and two court cards. Egypt By the 11th century, playing cards were spreading throughout the Asian continent and later came into Egypt. The oldest surviving cards in the world are four fragments found in the Keir Collection and one in the Benaki Museum. They are dated to the 12th and 13th centuries (late Fatimid, Ayyubid, and early Mamluk periods). A near complete pack of Mamluk playing cards dating to the 15th century and of similar appearance to the fragments above was discovered by Leo Aryeh Mayer in the Topkapı Palace, Istanbul, in 1939. It is not a complete set and is actually composed of three different packs, probably to replace missing cards. The Topkapı pack originally contained 52 cards comprising four suits: polo-sticks, coins, swords, and cups. Each suit contained ten pip cards and three court cards, called malik (king), nā'ib malik (viceroy or deputy king), and thānī nā'ib (second or under-deputy). The thānī nā'ib is a non-existent title so it may not have been in the earliest versions; without this rank, the Mamluk suits would structurally be the same as a Ganjifa suit. In fact, the word "Kanjifah" appears in Arabic on the king of swords and is still used in parts of the Middle East to describe modern playing cards. Influence from further east can explain why the Mamluks, most of whom were Central Asian Turkic Kipchaks, called their cups tuman, which means "myriad" (10,000) in the Turkic, Mongolian and Jurchen languages. Wilkinson postulated that the cups may have been derived from inverting the Chinese and Jurchen ideogram for "myriad", , which was pronounced as something like man in Middle Chinese. The Mamluk court cards showed abstract designs or calligraphy not depicting persons possibly due to religious proscription in Sunni Islam, though they did bear the ranks on the cards. Nā'ib would be borrowed into French (nahipi), Italian (naibi), and Spanish (naipes), the latter word still in common usage. Panels on the pip cards in two suits show they had a reverse ranking, a feature found in madiao, ganjifa, and old European card games like ombre, tarot, and maw. A fragment of two uncut sheets of Moorish-styled cards of a similar but plainer style was found in Spain and dated to the early 15th century. Export of these cards (from Cairo, Alexandria, and Damascus), ceased after the fall of the Mamluks in the 16th century. The rules to play these games are lost but they are believed to be plain trick games without trumps. Spread across Europe and early design changes The earliest record of playing cards in Europe is believed by some researchers to be a ban on card games in the city of Bern in 1367, although this source is questionable. Generally accepted as the first is a Florentine ban dating to 1377. Also appearing in 1377 was the treatise by John of Rheinfelden, in which he describes playing cards and their moral meaning. From this year onwards more and more records (usually bans) of playing cards occur, first appearing in England as early as 1413. Among the early patterns of playing card were those probably derived from the Mamluk suits of cups, coins, swords, and polo-sticks, which are still used in traditional Latin decks. As polo was an obscure sport to Europeans then, the polo-sticks became batons or cudgels. Their presence is attested in Catalonia in 1371, 1377 in Switzerland, and 1380 in many locations including Florence and Paris. Wide use of playing cards in Europe can, with some certainty, be traced from 1377 onward. In the account books of Johanna, Duchess of Brabant and Wenceslaus I, Duke of Luxembourg, an entry dated May 14, 1379, by receiver general of Brabant Renier Hollander reads: "Given to Monsieur and Madame four peters and two florins, worth eight and a half sheep, for the purchase of packs of cards". In his book of accounts for 1392 or 1393, Charles or Charbot Poupart, treasurer of the household of Charles VI of France, records payment for the painting of three sets of cards. From about 1418 to 1450 professional card makers in Ulm, Nuremberg, and Augsburg created printed decks. Playing cards even competed with devotional images as the most common uses for woodcuts in this period. Most early woodcuts of all types were coloured after printing, either by hand or, from about 1450 onwards, stencils. These 15th-century playing cards were probably painted. The Flemish Hunting Deck, held by the Metropolitan Museum of Art, is the oldest complete set of ordinary playing cards made in Europe from the 15th century. As cards spread from Italy to Germanic countries, the Latin suits were replaced with the suits of leaves (or shields), hearts (or roses), bells, and acorns, and a combination of Latin and Germanic suit pictures and names resulted in the French suits of (clovers), (tiles), (hearts), and (pikes) around 1480. The trèfle (clover) was probably derived from the acorn and the (pike) from the leaf of the German suits. The names and spade, however, may have derived from the sword () of the Italian suits. In England, the French suits were eventually used, although the earliest packs circulating may have had Latin suits. This may account for why the English called the clovers "clubs" and the pikes "spades". In the late 14th century, Europeans changed the Mamluk court cards to represent European royalty and attendants. In a description from 1377, the earliest courts were originally a seated "king", an upper marshal that held his suit symbol up, and a lower marshal that held it down. The latter two correspond with the ober and unter cards found in German and Swiss playing cards. The Italians and Iberians replaced the / system with the "Knight" and "" or "" before 1390, perhaps to make the cards more visually distinguishable. In England, the lowest court card was called the "knave" which originally meant male child (compare German ), so in this context the character could represent the "prince", son to the king and queen; the meaning servant developed later. Queens appeared sporadically in packs as early as 1377, especially in Germany. Although the Germans abandoned the queen before the 1500s, the French permanently |
they represent a data source that is not limited to animals with easily fossilised hard parts, and they reflect organisms' behaviours. Also many traces date from significantly earlier than the body fossils of animals that are thought to have been capable of making them. Whilst exact assignment of trace fossils to their makers is generally impossible, traces may for example provide the earliest physical evidence of the appearance of moderately complex animals (comparable to earthworms). Geochemical observations Geochemical observations may help to deduce the global level of biological activity at a certain period, or the affinity of certain fossils. For example, geochemical features of rocks may reveal when life first arose on Earth, and may provide evidence of the presence of eukaryotic cells, the type from which all multicellular organisms are built. Analyses of carbon isotope ratios may help to explain major transitions such as the Permian–Triassic extinction event. Classifying ancient organisms Naming groups of organisms in a way that is clear and widely agreed is important, as some disputes in paleontology have been based just on misunderstandings over names. Linnaean taxonomy is commonly used for classifying living organisms, but runs into difficulties when dealing with newly discovered organisms that are significantly different from known ones. For example: it is hard to decide at what level to place a new higher-level grouping, e.g. genus or family or order; this is important since the Linnaean rules for naming groups are tied to their levels, and hence if a group is moved to a different level it must be renamed. Simple example cladogram Warm-bloodedness evolved somewhere in thesynapsid–mammal transition. Warm-bloodedness must also have evolved at one of these points – an example of convergent evolution. Paleontologists generally use approaches based on cladistics, a technique for working out the evolutionary "family tree" of a set of organisms. It works by the logic that, if groups B and C have more similarities to each other than either has to group A, then B and C are more closely related to each other than either is to A. Characters that are compared may be anatomical, such as the presence of a notochord, or molecular, by comparing sequences of DNA or proteins. The result of a successful analysis is a hierarchy of clades – groups that share a common ancestor. Ideally the "family tree" has only two branches leading from each node ("junction"), but sometimes there is too little information to achieve this and paleontologists have to make do with junctions that have several branches. The cladistic technique is sometimes fallible, as some features, such as wings or camera eyes, evolved more than once, convergently – this must be taken into account in analyses. Evolutionary developmental biology, commonly abbreviated to "Evo Devo", also helps paleontologists to produce "family trees", and understand fossils. For example, the embryological development of some modern brachiopods suggests that brachiopods may be descendants of the halkieriids, which became extinct in the Cambrian period. Estimating the dates of organisms Paleontology seeks to map out how living things have changed through time. A substantial hurdle to this aim is the difficulty of working out how old fossils are. Beds that preserve fossils typically lack the radioactive elements needed for radiometric dating. This technique is our only means of giving rocks greater than about 50 million years old an absolute age, and can be accurate to within 0.5% or better. Although radiometric dating requires very careful laboratory work, its basic principle is simple: the rates at which various radioactive elements decay are known, and so the ratio of the radioactive element to the element into which it decays shows how long ago the radioactive element was incorporated into the rock. Radioactive elements are common only in rocks with a volcanic origin, and so the only fossil-bearing rocks that can be dated radiometrically are a few volcanic ash layers. Consequently, paleontologists must usually rely on stratigraphy to date fossils. Stratigraphy is the science of deciphering the "layer-cake" that is the sedimentary record, and has been compared to a jigsaw puzzle. Rocks normally form relatively horizontal layers, with each layer younger than the one underneath it. If a fossil is found between two layers whose ages are known, the fossil's age must lie between the two known ages. Because rock sequences are not continuous, but may be broken up by faults or periods of erosion, it is very difficult to match up rock beds that are not directly next to one another. However, fossils of species that survived for a relatively short time can be used to link up isolated rocks: this technique is called biostratigraphy. For instance, the conodont Eoplacognathus pseudoplanus has a short range in the Middle Ordovician period. If rocks of unknown age are found to have traces of E. pseudoplanus, they must have a mid-Ordovician age. Such index fossils must be distinctive, be globally distributed and have a short time range to be useful. However, misleading results are produced if the index fossils turn out to have longer fossil ranges than first thought. Stratigraphy and biostratigraphy can in general provide only relative dating (A was before B), which is often sufficient for studying evolution. However, this is difficult for some time periods, because of the problems involved in matching up rocks of the same age across different continents. Family-tree relationships may also help to narrow down the date when lineages first appeared. For instance, if fossils of B or C date to X million years ago and the calculated "family tree" says A was an ancestor of B and C, then A must have evolved more than X million years ago. It is also possible to estimate how long ago two living clades diverged – i.e. approximately how long ago their last common ancestor must have lived – by assuming that DNA mutations accumulate at a constant rate. These "molecular clocks", however, are fallible, and provide only a very approximate timing: for example, they are not sufficiently precise and reliable for estimating when the groups that feature in the Cambrian explosion first evolved, and estimates produced by different techniques may vary by a factor of two. History of life Earth formed about and, after a collision that formed the Moon about 40 million years later, may have cooled quickly enough to have oceans and an atmosphere about . There is evidence on the Moon of a Late Heavy Bombardment by asteroids from . If, as seems likely, such a bombardment struck Earth at the same time, the first atmosphere and oceans may have been stripped away. Paleontology traces the evolutionary history of life back to over , possibly as far as . The oldest clear evidence of life on Earth dates to , although there have been reports, often disputed, of fossil bacteria from and of geochemical evidence for the presence of life . Some scientists have proposed that life on Earth was "seeded" from elsewhere, but most research concentrates on various explanations of how life could have arisen independently on Earth. For about 2,000 million years microbial mats, multi-layered colonies of different bacteria, were the dominant life on Earth. The evolution of oxygenic photosynthesis enabled them to play the major role in the oxygenation of the atmosphere from about . This change in the atmosphere increased their effectiveness as nurseries of evolution. While eukaryotes, cells with complex internal structures, may have been present earlier, their evolution speeded up when they acquired the ability to transform oxygen from | by solving the "jigsaw puzzles" of biostratigraphy (arrangement of rock layers from youngest to oldest). Classifying ancient organisms is also difficult, as many do not fit well into the Linnaean taxonomy classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring the similarity of the DNA in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend. Overview The simplest definition of "paleontology" is "the study of ancient life". The field seeks information about several aspects of past organisms: "their identity and origin, their environment and evolution, and what they can tell us about the Earth's organic and inorganic past". Historical science William Whewell (1794–1866) classified paleontology as one of the historical sciences, along with archaeology, geology, astronomy, cosmology, philology and history itself: paleontology aims to describe phenomena of the past and to reconstruct their causes. Hence it has three main elements: description of past phenomena; developing a general theory about the causes of various types of change; and applying those theories to specific facts. When trying to explain the past, paleontologists and other historical scientists often construct a set of one or more hypotheses about the causes and then look for a "smoking gun", a piece of evidence that strongly accords with one hypothesis over any others. Sometimes researchers discover a "smoking gun" by a fortunate accident during other research. For example, the 1980 discovery by Luis and Walter Alvarez of iridium, a mainly extraterrestrial metal, in the Cretaceous–Tertiary boundary layer made asteroid impact the most favored explanation for the Cretaceous–Paleogene extinction event – although debate continues about the contribution of volcanism. A complementary approach to developing scientific knowledge, experimental science, is often said to work by conducting experiments to disprove hypotheses about the workings and causes of natural phenomena. This approach cannot prove a hypothesis, since some later experiment may disprove it, but the accumulation of failures to disprove is often compelling evidence in favor. However, when confronted with totally unexpected phenomena, such as the first evidence for invisible radiation, experimental scientists often use the same approach as historical scientists: construct a set of hypotheses about the causes and then look for a "smoking gun". Related sciences Paleontology lies between biology and geology since it focuses on the record of past life, but its main source of evidence is fossils in rocks. For historical reasons, paleontology is part of the geology department at many universities: in the 19th and early 20th centuries, geology departments found fossil evidence important for dating rocks, while biology departments showed little interest. Paleontology also has some overlap with archaeology, which primarily works with objects made by humans and with human remains, while paleontologists are interested in the characteristics and evolution of humans as a species. When dealing with evidence about humans, archaeologists and paleontologists may work together – for example paleontologists might identify animal or plant fossils around an archaeological site, to discover the people who lived there, and what they ate; or they might analyze the climate at the time of habitation. In addition, paleontology often borrows techniques from other sciences, including biology, osteology, ecology, chemistry, physics and mathematics. For example, geochemical signatures from rocks may help to discover when life first arose on Earth, and analyses of carbon isotope ratios may help to identify climate changes and even to explain major transitions such as the Permian–Triassic extinction event. A relatively recent discipline, molecular phylogenetics, compares the DNA and RNA of modern organisms to re-construct the "family trees" of their evolutionary ancestors. It has also been used to estimate the dates of important evolutionary developments, although this approach is controversial because of doubts about the reliability of the "molecular clock". Techniques from engineering have been used to analyse how the bodies of ancient organisms might have worked, for example the running speed and bite strength of Tyrannosaurus, or the flight mechanics of Microraptor. It is relatively commonplace to study the internal details of fossils using X-ray microtomography. Paleontology, biology, archaeology, and paleoneurobiology combine to study endocranial casts (endocasts) of species related to humans to clarify the evolution of the human brain. Paleontology even contributes to astrobiology, the investigation of possible life on other planets, by developing models of how life may have arisen and by providing techniques for detecting evidence of life. Subdivisions As knowledge has increased, paleontology has developed specialised subdivisions. Vertebrate paleontology concentrates on fossils from the earliest fish to the immediate ancestors of modern mammals. Invertebrate paleontology deals with fossils such as molluscs, arthropods, annelid worms and echinoderms. Paleobotany studies fossil plants, algae, and fungi. Palynology, the study of pollen and spores produced by land plants and protists, straddles paleontology and botany, as it deals with both living and fossil organisms. Micropaleontology deals with microscopic fossil organisms of all kinds. Instead of focusing on individual organisms, paleoecology examines the interactions between different ancient organisms, such as their food chains, and the two-way interactions with their environments. For example, the development of oxygenic photosynthesis by bacteria caused the oxygenation of the atmosphere and hugely increased the productivity and diversity of ecosystems. Together, these led to the evolution of complex eukaryotic cells, from which all multicellular organisms are built. Paleoclimatology, although sometimes treated as part of paleoecology, focuses more on the history of Earth's climate and the mechanisms that have changed it – which have sometimes included evolutionary developments, for example the rapid expansion of land plants in the Devonian period removed more carbon dioxide from the atmosphere, reducing the greenhouse effect and thus helping to cause an ice age in the Carboniferous period. Biostratigraphy, the use of fossils to work out the chronological order in which rocks were formed, is useful to both paleontologists and geologists. Biogeography studies the spatial distribution of organisms, and is also linked to geology, which explains how Earth's geography has changed over time. Sources of evidence Body fossils Fossils of organisms' bodies are usually the most informative type of evidence. The most common types are wood, bones, and shells. Fossilisation is a rare event, and most fossils are destroyed by erosion or metamorphism before they can be observed. Hence the fossil record is very incomplete, increasingly so further back in time. Despite this, it is often adequate to illustrate the broader patterns of life's history. There are also biases in the fossil record: different environments are more favorable to the preservation of different types of organism or parts of organisms. Further, only the parts of organisms that were already mineralised are usually preserved, such as the shells of molluscs. Since most animal species are soft-bodied, they decay before they can become fossilised. As a result, although there are 30-plus phyla of living animals, two-thirds have never been found as fossils. Occasionally, unusual environments may preserve soft tissues. These lagerstätten allow paleontologists to examine the internal anatomy of animals that in other sediments are represented only by shells, spines, claws, etc. – if they are preserved at all. However, even lagerstätten present an incomplete picture of life at the time. The majority of organisms living at the time are probably not represented because lagerstätten are restricted to a narrow range of environments, e.g. where soft-bodied organisms can be preserved very quickly by events such as mudslides; and the exceptional events that cause quick burial make it difficult to study the normal environments of the animals. The sparseness of the fossil record means that organisms are expected to exist long before and after they are found in the fossil record – this is known as the Signor–Lipps effect. Trace fossils Trace fossils consist mainly of tracks and burrows, but also include coprolites (fossil feces) and marks left by feeding. Trace fossils are particularly significant because they represent a data source that is not limited to animals with easily fossilised hard parts, and they reflect organisms' behaviours. Also many traces date from significantly earlier than the body fossils of animals that are thought to have been capable of making them. Whilst exact assignment of trace fossils to their makers is generally impossible, traces may for example provide the earliest physical evidence of the appearance of moderately complex animals (comparable to earthworms). Geochemical observations Geochemical observations may help to deduce the global level of biological activity at a certain period, or the affinity of certain fossils. For example, geochemical features of rocks may reveal when life first arose on Earth, and may provide evidence of the presence of eukaryotic cells, the type from which all multicellular organisms are built. Analyses of carbon isotope ratios may help to explain major transitions such as the Permian–Triassic extinction event. Classifying ancient organisms Naming groups of organisms in a way that is clear and widely agreed is important, as some disputes in paleontology have been based just on misunderstandings over names. Linnaean taxonomy is commonly used for classifying living organisms, but runs into difficulties when dealing with newly discovered organisms that are significantly different from known ones. For |

The paper was supplied in roll form and had perforations along both edges that were engaged by sprockets on the rollers. Another approach, e.g. Computervision's Interact I, involved attaching ball-point pens to drafting pantographs and driving the machines with stepper motors controlled by the computer. This had the disadvantage of being somewhat slow to move, as well as requiring floor space equal to the size of the paper, but could double as a digitizer. A later change was the addition of an electrically controlled clamp to hold the pens, which allowed them to be changed, and thus create multi-colored output. Hewlett Packard and Tektronix produced small, desktop-sized flatbed plotters in the late 1960s and 1970s. The pens were mounted on a traveling bar, whereby the y-axis was represented by motion up and down the length of the bar and the x-axis was represented by motion of the bar back and forth across the plotting table. Due to the mass of the bar, these plotters operated relatively slowly. In the 1980s, the small and lightweight HP 7470 introduced the "grit wheel" mechanism, eliminating the need for perforations along the edges, unlike the Calcomp plotters two decades earlier. The grit wheels at opposite edges of the sheet press against resilient polyurethane-coated rollers and form tiny indentations in the sheet. As the sheet is moved back and forth, the grit wheels keep the sheet in proper registration due to the grit particles falling into the earlier indentations, much like the teeth of two gears meshing. The pen is mounted on a carriage that moves back and forth in a line between the grit wheels, representing the orthogonal axis. These smaller "home-use" plotters became popular for desktop business graphics and in engineering laboratories, but their low speed meant they were not useful for general printing purposes, and different conventional printer would be required for those jobs. One category, introduced by Hewlett Packard's MultiPlot for the HP 2647, was the "word chart", which used the plotter to draw large letters on a transparency. This was the forerunner of the modern Powerpoint chart. With the widespread availability of high-resolution inkjet and laser printers, inexpensive memory and computers fast enough to rasterize color images, pen plotters have all but disappeared. However, the grit wheel mechanism is still found in inkjet-based, large format engineering plotters. Plotters were also used in the Create-A-Card kiosks that were available for a while in the greeting card area of supermarkets that used the HP 7475 six-pen plotter. Plotters are used primarily in technical drawing and CAD applications, where they have the advantage of working on very large paper sizes while maintaining high resolution. Another use has been found by replacing the pen with a cutter, and in this form plotters can be found in many garment and sign shops. Changing the color or width of a line required the plotter to change pens. This was either done manually on small plotters, but more typically the plotter would have a magazine of four or more pens which could be automatically mounted. A niche application of plotters is in creating tactile images for visually handicapped people on special thermal cell paper. Unlike other printer types, pen plotter speed is measured by pen speed and acceleration rate, instead of by page printing speed. A pen plotter's speed is primarily limited by the type of pen used, so the choice of pen is a key factor in pen plotter output speed. Indeed, most modern pen plotters have commands to control slewing speed, depending on the type of pen currently in use. There are many types of plotter pen, some of which are no longer mass-produced. Technical pen tips are often used, many of which can be renewed using parts and supplies for manual drafting pens. Early HP flatbed and grit wheel plotters used small, proprietary fiber-tipped or plastic nib disposable pens. One type of plotter pen uses a cellulose fiber rod inserted through a circular foam tube saturated with ink, with the end of the rod sharpened into a conical tip. As the pen moves across the paper surface, capillary wicking draws the ink from the foam, down the rod, and onto the paper. As the ink supply in the foam is depleted, the migration of ink to the | number of close, regular lines. Plotters offered the fastest way to efficiently produce very large drawings or color high-resolution vector-based artwork when computer memory was very expensive and processor power was very limited, and other types of printers had limited graphic output capabilities. Pen plotters have essentially become obsolete, and have been replaced by large-format inkjet printers and LED toner-based printers. Such devices may still understand vector languages originally designed for plotter use, because in many uses, they offer a more efficient alternative to raster data. Electrostatic plotters Electrostatic plotters used a dry toner transfer process similar to that in many photocopiers. They were faster than pen plotters and were available in large formats, suitable for reproducing engineering drawings. The quality of image was often not as good as contemporary pen plotters. Electrostatic plotters were made in both flat-bed and drum types. The electrostatic plotter uses the pixel as a drawing means, like a raster graphics display device. The plotter head consists of a large number of tiny styluses (as many as 21760) embedded in it. This head traverses over the width of the paper as it rolls past the head to make a drawing. The resolutions available may be 100 to 508 dots per inch. Electrostatic plotters are very fast with plotting speed of 6 to 32 mm/s, depending on the plotter resolution. Cutting plotters Cutting plotters use knives to cut into a piece of material (such as paper, mylar film, or vinyl film) that is lying on the flat surface area of the plotter. The cutting plotter is connected to a computer, which is equipped with cutting design or drawing computer software programs. Those computer software programs are responsible for sending the necessary cutting dimensions or designs in order to command the cutting knife to produce the correct project cutting needs. In recent years the use of cutting plotters (generally called die-cut machines) has become popular with home enthusiasts of paper crafts such as cardmaking and scrapbooking. Such tools allow desired card and decal shapes to be cut out very precisely, and repeatably. History A number of printer control languages were created to operate pen plotters, and transmit commands like "lift pen from paper", "place pen on paper", or "draw a line from here to here". Three common ASCII-based plotter control languages are Hewlett-Packard's HP-GL, its successor HP-GL/2, and Houston Instruments DMPL. Here is a simple HP-GL script drawing a line: SP1; PA500,500; PD; PR0,1000; PU; SP; This program instructs the plotter, in order, to take the first pen (SP1 = Select Pen 1), to go to coordinates X=500, Y=500 on the paper sheet (PA = Plot Absolute), to lower the pen against the paper (PD = Pen Down), to move 1000 units in the Y direction (thus drawing a vertical line - PR = Plot Relative), to lift the pen (PU = Pen Up) and finally to put it back in its stall. Programmers using FORTRAN or BASIC generally did not program these directly, but used software packages, such as the Calcomp library, or device independent graphics packages, such as Hewlett-Packard's AGL libraries or BASIC extensions or high end packages such as DISSPLA. These would establish scaling factors from world coordinates to device coordinates, and translate to the low level device commands. For example, to plot X*X in HP 9830 BASIC, the program would be 10 SCALE -1,1,1,1 20 FOR X = -1 to 1 STEP 0.1 30 PLOT X, X*X 40 NEXT X 50 PEN 60 END Early pen plotters, e.g., the Calcomp 565 of 1959, worked by placing the paper over a roller that moved the paper back and forth for X motion, while the pen moved back and forth on a track for Y motion.

There is also a variation of the "Fully Wild" rule in which the wild card (in this instance they are usually jokers as there are traditionally only two and there is only one black and one red) can be any card of the suits matching the cards colour or current suit. For example, in a jokers wild game with these rules, the red joker could be used as any card of hearts or diamonds. Inversely, the black joker would be any card of clubs or spades. Two exceptions to standard poker practice sometimes seen in home games are the double-ace flush rule, and the natural wins rule. The latter | must be agreed upon by all players before the cards are dealt and play commences. There are two common rules regarding wild cards: "fully wild" cards and the "bug". A card that is fully wild can be designated by its holder as any card they choose with no restrictions. Under this rule, for example, a hand with any natural pair and a wild card becomes three of a kind. Conversely, a bug is a limited wild. The common rule in casinos is that a wild card plays as a bug, which is given the rank of ace unless designating it as a different card would complete a straight, flush, or straight flush. Under this rule, a hand such as K-K-Joker-5-2 is just a pair of kings (with an ace kicker), but any four same-suit cards with a bug make a flush, and a hand such as 7-Joker-5-4-3 makes a straight.

those who declared high wins that half (for further details, see declaration). In a cards speak game, all players simply reveal their cards at showdown and the hands are evaluated by all players; high hand wins half of the pot and low hand wins the other half. Especially when using the ace-to-five low method, it is possible for one player to have both the low hand and the high hand, and therefore win all of the pot (called "scooping," "hogging" the pot, or "going pig"). In the event more than one player ties for either high or low, the pot can be further split into quarters or smaller fractions. For example, if one player has the high hand on showdown, and two other players tie for the best low hand, the high hand wins half of the pot and each low hand wins only a quarter of the pot. It is common, especially in cards speak games, to require a certain hand value or better to win the low half of the pot, called a qualifier. For example, in an "eight or better to qualify low" game, a player with a hand of eight-high or lower is entitled to win the low half of the pot (assuming his hand defeats all other low hands), but a player with a 10-high or 9-high hand cannot win, even if his hand is the lowest. In this case, the high hand wins the entire pot. There is generally no qualifier to win high, although one common variant is any | has the high hand on showdown, and two other players tie for the best low hand, the high hand wins half of the pot and each low hand wins only a quarter of the pot.

For example, in an "eight or better to qualify low" game, a player with a hand of eight-high or lower is entitled to win the low half of the pot (assuming his hand defeats all other low hands), but a player with a 10-high or 9-high hand cannot win, even if his hand is the lowest. In this case, the high hand wins the entire pot. There is generally no qualifier to win high, although one common variant is any pair/no pair, where a hand of at least a pair is required to win high and any hand with no pair is required to win low. In high-low split games where each player is dealt more than five cards, each player chooses five of his cards to play as his high hand, and/or five of his cards to play as his low hand. The sets may overlap: for example, in seven-card stud played high-low split, a player dealt 7-7-6-4-4-3-2 can play a high hand of 7-7-4-4-6 (two pair, sevens and fours) and a low hand of 7-6-4-3-2 (seven-high).

would win (because its K kicker outranks the 10), but Q-Q-10-4-3 would lose (because its 4 is outranked by the 5). Kickers in draw poker The term is also used in draw poker to denote an unmatched card (often an ace) retained by a player during the draw in the hope that either it will be paired on the draw, or else play as a kicker (in the first sense) on the showdown. A kicker may also be retained in order to deceive an opponent, for example, to represent a three-of-a-kind when the player has only a pair. Kickers in Texas hold 'em Kickers take on special importance in Texas hold 'em, because a common winning hand is one card in a player's hand matched with a card on the board, while the player's second card acts as a kicker. For example, if one player holds A-8, a second player holds A-7, and the board is A-K-6-5-4, the player with | have a pair of queens. For example, Q-Q-K-3-2 would win (because its K kicker outranks the 10), but Q-Q-10-4-3 would lose (because its 4 is outranked by the 5).

cardrooms offer "short stack" tables where the maximum buy-in is 50 big blinds or less and/or "deep stack" tables where the minimum buy-in is 100 big blinds or more. Missed blinds In cash games that do not deal cards to players who are absent from the table at the start of the hand (or, in online games, are designated as "sitting out"), special rules are necessary to deal with players who miss their blinds. In such a situation, if a player misses his or her big blind, he or she will not be dealt in again until the button has passed. At that point, if the player wishes to rejoin the game, he or she must "super-post" - he or she must post both the big and small blinds in order to be dealt cards. Of these, only the big blind is considered "live" while the small blind is "dead" - it is placed in the center of the pot apart from the big blind and will not count towards calling any additional bets or raises by other players. If the player has only missed the small blind, then the same procedure applies except that the player only has to post the "dead" small blind to rejoin the game. Most cardrooms allow players to relieve themselves of these obligations if they wait until they are again due to post the big blind before rejoining the game. Some cardrooms hosting live cash games do not allow players to miss and/or avoid paying blinds in this manner. In these games, all players with chips on the table are dealt in whether or not they are present at the table. Any blinds due will be posted from the player's stack - depending on the cardroom's rules this will be done either by the dealer, another cardroom employee or a nearby player under staff supervision. Whenever a player has not returned to the table by the time it is his turn to act, his or her hand is automatically folded. Under such rules, if a player wishes to be absent from the table then the only way he or she can avoid paying blinds is to cash out and leave the game altogether. Blinds in tournament play In poker tournament play, blinds serve a dual purpose. In addition to the purpose explained above, blinds are also used to control how long the tournament will last. Before the tournament begins, the players will agree to a blinds structure, usually set by the tournament organizer. This structure defines how long each round is and how much the blinds increase per round. Typically, they are increased at a smooth rate of between 25% and 50% per round over the previous round. As the blinds increase, players need to increase their chip counts (or "stacks") to stay in the game. The blinds will eventually consume all of a player's stack if he or she does not play to win more. Unlike many cash games, it is not possible for a player to "miss" blinds in a tournament. If a player is absent from the table, he will continue to have his or her cards dealt and mucked and will have blinds and, if applicable, antes taken from his stack as they are | known as a live blind. If the live blind checks, the betting round then ends. After the flop, turn and river, the first person to act is the player seated in the small blind position. Generally, the "big blind" is equal to the minimum bet. The "small blind" is normally half the big blind. In cases where posting exactly half the big blind is impractical due to the big blind being some odd-valued denomination, the small blind is rounded (usually down) to the nearest practical value. For example, if the big blind in a live table game is $3, then the small blind will usually be $1 or $2 since most casinos do not distribute large quantities of $0.50 poker chips. The blinds exist because Omaha and Texas hold 'em are frequently played without antes, allowing a player to fold his hand without placing a bet. The blind bets introduce a regular cost to take part in the game, thus inducing a player to enter pots in an attempt to compensate for that expense. It is possible to play without blinds. The minimum bet is then the lowest denomination chip in play, and tossing only one chip is considered as a call. Anything higher than that is considered a raise. Poker without blinds is usually played with everyone posting an ante to receive cards. Blinds in cash games In cash games, otherwise known as ring games, blinds primarily serve to ensure all players are subject to some minimum, ongoing cost for participating in the game. This encourages players to play hands they otherwise might not, thereby increasing the average size of the pots and, by extension, increasing the amount of rake earned by the cardroom hosting the game. In cash games, the amount of the blinds are normally fixed for each particular table and will not change for the duration of the game. However, many cardrooms will allow blind levels to change in cases where all players unanimously agree to a change. Larger cardrooms will often include tables with different blind levels to give players the option of playing at whatever stakes they are most comfortable with. In online poker, blinds range from as little as one U.S. cent to USD1,000 or more. The minimum and maximum buy-in at a table is usually set in relation to the big blind. At live games, the minimum buy-in is usually between 20 and 50 big blinds, while the maximum buy-in is usually between 100 and 250 |
is a situation when, if more than one player remains after the last betting round, remaining players expose and compare their hands to determine the winner or winners. To win any part of a pot if more than one player has a hand, a player must show all of their cards faceup on the table, whether those cards were used in the final hand played or not. Cards speak for themselves: the actual value of a player's hand prevails in the event a player mis-states the value of their hand. Because exposing a losing hand gives information to an opponent, players may be reluctant to expose their hands until after their opponents have done so and will muck their losing hands without exposing them. Robert's Rules of Poker state that the last player to take aggressive action by a bet or raise is the first to show the hand—unless everyone checks (or is all-in) on the last round of betting, then the first player to the left of the dealer button is the first to show the hand. If there is a side pot, players involved in the side pot should show their hands before | then the first player to the left of the dealer button is the first to show the hand. If there is a side pot, players involved in the side pot should show their hands before anyone who is all-in for only the main pot. To speed up the game, a player holding a probable winner is encouraged to show the hand without delay. Any player who has been dealt in may request to see any hand that is eligible to participate in the showdown, even if the hand has been mucked. This option is generally only used |
then raises in the same round. This might be done, for example, when the first player believes that an opponent has an inferior hand and will not call a direct bet, but that they may attempt to bluff, allowing the first player to win more money than they would by betting straightforwardly. The key point is that if no one else is keen to bet, then the most a player can raise by (in a limit game) is one single bet. If someone else bets first, they can raise, thus increasing the value of the pot by two bets. In a no-limit game, there is no restriction on the size of one's bet, and a raise is likely to be much larger than the second player's bet. Of course, if no other player chooses to open, the betting will be checked around and the play will have failed to elicit additional money for the pot. Like a simple check, a failed check-raise provides other players an opportunity to view the next card or cards dealt without requiring the other players to commit more money to the pot. A check-raise thus contains an element of risk because the check-raising player's advantage may deteriorate when new cards are revealed. While it can be an important part of one's poker strategy, this play is not allowed by a house rule in some home games and certain small-stakes | the pot.

While it can be an important part of one's poker strategy, this play is not allowed by a house rule in some home games and certain small-stakes casino games. It is also frequently not allowed in the game of California lowball. In older poker material and among stud and draw poker players, it is sometimes referred to as sandbagging. Check-raises can also be used as an intimidation technique over the course of a game; a player who has frequently been check-raised may be less likely to attempt to steal the pot. In online poker games special tracking software can be used to determine the exact percentage of times a player check-raised when they had the opportunity. This information helps to determine if a player who check-raised has a monster hand or is bluffing as part of their routine poker play. Not all players agree that a check-raise is an especially effective play, however. In Super/System, Doyle Brunson claims to check-raise very rarely |
exactly one card in his hand with a new one from the remaining deck stub. This is similar to the draw phase of draw poker, differing in the following way: if the player chooses to replace a downcard, he discards it and is dealt a replacement card also face down; if he wishes to replace an upcard, he discards it and receives the replacement face up. On a twist | in the following way: if the player chooses to replace a downcard, he discards it and is dealt a replacement card also face down; if he wishes to replace an upcard, he discards it and receives the replacement face up.

a piquet deck (or the equivalent German- or Swiss-suited decks) are still among the most popular in some parts of Europe. This includes belote and klaverjas (the national games of France and the Netherlands, respectively) and skat (the German national game, which is also played with the equivalent German-suited decks in some regions). Bezique is played with two piquet decks. In poker variants Stripped decks are used in certain poker variants. The earliest form of poker was played with only 20 cards. The Australian game of Manila uses a piquet deck, and Mexican stud is played with the 8s, 9s, and 10s removed from the deck (and a joker added). This may require adjusting hand values: in both of these games, a flush ranks above a full house, because having fewer cards of each suit available makes flushes rarer. A hand such as 6-7-J-Q-K plays as a straight in Mexican stud, skipping over the removed ranks. Some places may allow a hand such as 10-9-8-7-A to play as a straight (by analogy to a wheel) in the 32-card game, the A playing low and skipping over the removed ranks (although this is not the case in Manila). Finally, the relative frequency of straights versus three of a kind is also sensitive to the deck composition (and to the number of cards dealt), so some places may consider three of a kind to be superior to a straight, but the difference is small enough that this complication is not necessary for most games. Similarly, a full house tends to occur more often than a flush in a piquet deck, due to the increased frequency of each playing card rank, creating a change in poker combination ranking. Five-card stud is also often played with a piquet deck. In lively home games it might work better to only strip three ranks (2s through 4s) with seven or eight players; with only two or three players 7s and 8s could be stripped as well, leaving the same 24-card deck used in euchre. In any of these cases, a flush should rank above a full house (in a 24-card deck it is actually rarer than four of a kind, but is rarely played that flushes are superior to four of a kind). Stripped deck five-card stud is a game particularly well-suited to cheating by collusion, because it is easy for partners to signal a single hole card and the relative value of knowing the location of a single card is higher than with a full deck.
