"Continental Army",
"instance of",
"army"
] |
The Continental Army was the army of the United Colonies representing the Thirteen Colonies and later the United States during the American Revolutionary War. It was formed on June 14, 1775 by a resolution passed by the Second Continental Congress, meeting in Philadelphia after the war's outbreak. The Continental Army was created to coordinate military efforts of the colonies in the war against the British, who sought to maintain control over the American colonies. General George Washington was appointed commander-in-chief of the Continental Army and maintained this position throughout the war.
The Continental Army was supplemented by local militias and volunteer troops that were either loyal to individual states or otherwise independent. Most of the Continental Army was disbanded in 1783 after the Treaty of Paris formally ended the war. The Continental Army's 1st and 2nd Regiments went on to form what was to become the Legion of the United States in 1792, which ultimately served as the foundation for the creation of the U.S. Army.

"Culper Ring",
"founded by",
"George Washington"
] |
The Culper Ring was a network of spies active during the American Revolutionary War, organized by Major Benjamin Tallmadge and General George Washington in 1778 during the British occupation of New York City. The name "Culper" was suggested by George Washington and taken from Culpeper County, Virginia. The leaders of the spy ring were Abraham Woodhull and Robert Townsend, using the aliases of "Samuel Culper Sr." and "Samuel Culper Jr.", respectively; Tallmadge was referred to as "John Bolton".
While Tallmadge was the spies' direct contact, Washington often directed their operations. The ring was tasked to provide Washington information on British Army operations in New York City, the British headquarters. Its members operated mostly in New York City, Long Island, and Connecticut between late October 1778 and the British evacuation of New York in 1783.
The information supplied by the spy ring included details of a surprise attack on the newly arrived French forces under Lieutenant General Rochambeau at Newport, Rhode Island, before they had recovered from their arduous sea voyage, as well as a British plan to counterfeit American currency on the actual paper used for Continental dollars, which prompted the Continental Congress to retire the bills.
The ring also informed Washington that Tryon's raid of July 1779 was intended to divide his forces and allow Lieutenant General Sir Henry Clinton to attack them piecemeal. In 1780, the Culper Ring discovered a high-ranking American officer, subsequently identified as Benedict Arnold, was plotting with British Major John André to turn over the vitally important American fort at West Point, New York on the Hudson River and surrender its garrison to the British forces.

History
The Park Watchmen were first recruited in 1791 by George Washington to protect federal property in the District of Columbia. The police functioned as an independent agency of the federal government until 1849, when it was placed under the jurisdiction of the Department of the Interior. In 1867, Congress transferred the police to the Office of Public Buildings and Grounds, under the supervision of the Chief of Engineers of the Army Corps of Engineers. The Watchmen were given the same powers and duties as the Metropolitan Police of Washington in 1882. Their name was officially changed to the present United States Park Police in 1919. In 1925, Congress placed the Park Police in the newly created Office of Public Buildings and Public Parks of the National Capital. Headed by an Army officer, Lt. Col. Ulysses S. Grant III, the office reported directly to the President of the United States. In 1933, President Franklin Delano Roosevelt transferred the police to the National Park Service.Their authority first began to expand outside D.C. in 1929, and today they are primarily responsible for the Gateway National Recreation Area units in New York City-New Jersey and the Golden Gate National Recreation Area in San Francisco, as well as the many designated areas in Washington D.C. and the neighboring counties in Maryland and Virginia. These sites include the National Mall, the C&O Canal towpath in the region, and the parallel roadways of the George Washington Memorial Parkway in Virginia and Clara Barton Parkway in Maryland, as well as the federally maintained segment of the Baltimore Washington Parkway in Maryland.

The United States Park Police (USPP) is one of the oldest uniformed federal law enforcement agencies in the United States. It functions as a full-service law enforcement agency with responsibilities and jurisdiction in those National Park Service areas primarily located in the Washington, D.C., San Francisco, and New York City areas and certain other government lands. United States Park Police officers have jurisdictional authority in the surrounding metropolitan areas of the three cities it primarily operates in, meaning they possess both state and federal authority. In addition to performing the normal crime prevention, investigation, and apprehension functions of an urban police force, the Park Police are responsible for policing many of the famous monuments in the United States.
The USPP shares law enforcement jurisdiction in all lands administered by the National Park Service with a force of National Park Service Law Enforcement Rangers tasked with the same law enforcement powers and responsibilities. The agency also provides protection for the President, Secretary of the Interior, and visiting dignitaries. The Park Police is an operation of the National Park Service, which is an agency of the Department of the Interior. As of April 8, 2022, the force consisted of 494 officers.History

History
Foundation
After World War II, many European scientists left Western Europe in order to work with the United States. Although the 1950s boom made it possible for Western European countries to invest in research and specifically in space-related activities, Western European scientists realised solely national projects would not be able to compete with the two main superpowers. In 1958, only months after the Sputnik shock, Edoardo Amaldi (Italy) and Pierre Auger (France), two prominent members of the Western European scientific community, met to discuss the foundation of a common Western European space agency. The meeting was attended by scientific representatives from eight countries.
The Western European nations decided to have two agencies: one concerned with developing a launch system, ELDO (European Launcher Development Organisation), and the other the precursor of the European Space Agency, ESRO (European Space Research Organisation). The latter was established on 20 March 1964 by an agreement signed on 14 June 1962. From 1968 to 1972, ESRO launched seven research satellites, but ELDO was not able to deliver a launch vehicle. Both agencies struggled with underfunding and diverging interests of its participants.
ESA in its current form was founded with the ESA Convention in 1975, when ESRO was merged with ELDO. ESA had ten founding member states: Belgium, Denmark, France, West Germany, Italy, the Netherlands, Spain, Sweden, Switzerland, and the United Kingdom. These signed the ESA Convention in 1975 and deposited the instruments of ratification by 1980, when the convention came into force. During this interval the agency functioned in a de facto fashion. ESA launched its first major scientific mission in 1975, Cos-B, a space probe monitoring gamma-ray emissions in the universe, which was first worked on by ESRO.Mission
The treaty establishing the European Space Agency reads:
The purpose of the Agency shall be to provide for and to promote, for exclusively peaceful purposes, cooperation among European States in space research and technology and their space applications, with a view to their being used for scientific purposes and for operational space applications systems…
ESA is responsible for setting a unified space and related industrial policy, recommending space objectives to the member states, and integrating national programs like satellite development, into the European program as much as possible.Jean-Jacques Dordain – ESA's Director General (2003–2015) – outlined the European Space Agency's mission in a 2003 interview:
Today space activities have pursued the benefit of citizens, and citizens are asking for a better quality of life on Earth. They want greater security and economic wealth, but they also want to pursue their dreams, to increase their knowledge, and they want younger people to be attracted to the pursuit of science and technology.
I think that space can do all of this: it can produce a higher quality of life, better security, more economic wealth, and also fulfill our citizens' dreams and thirst for knowledge, and attract the young generation. This is the reason space exploration is an integral part of overall space activities. It has always been so, and it will be even more important in the future.

Columbia Country Club Camp was a Japanese internment camp for civilian detainees in Shanghai, China during World War II. It was located in what was then the city outskirts, at 301 Great Western Road (now Yan'an West Road). (For additional camps, see List of Japanese-run internment camps during World War II.)
Currently, the site is now a part of Shanghai Institute of Biological Products, at 1262 Yan'an West Road.Internment
During the fall of 1942 and winter of 1943, the Japanese Army used the Club to house enemy nationals, removed from out ports, who awaited repatriation. When influential Shanghailanders gained access to berths on the few available ships, many inmates became stranded there.In May 1943, the Club became an internment camp for civilians. Space was extremely limited and internees were forced to sleep in the bowling alley, bars, and other club rooms. The swimming pool remained in use initially, but with no chemicals to maintain it, the water was eventually drained. Hundreds stayed at the CCC at any one time; 386 total civilians were interned there. Many were the older couples without family, complicating the death rates at the camp.
In April 1945, and prior to liberation, all remaining internees were removed to the Yangtzepoo POW Camp.

History
The FCI was founded in 1911 under the auspices of the kennel clubs of Austria, Belgium, France, Germany and the Netherlands. Its objective was to bring global uniformity to the breeding, exhibiting and judging of pure-bred dogs. It was disbanded in World War I and recreated in 1921 by Belgium and France. Since its foundation the FCI's membership has grown to include kennel clubs from across Europe as well as Africa, the Americas, Asia and Oceania.The official purebred registries in North America that are not members or contract partners of FCI include the American Kennel Club (AKC), Canadian Kennel Club (CKC) and United Kennel Club (UKC), and in Europe, The Kennel Club (TKC). According to AKC's Denise Flaim, crafting a workable standard is a challenge, and the "FCI standards typically have a greater number of disqualifications, which are sometimes subjective, and their impact on a dog's career is not as dire."

"First Geneva Convention",

The International Committee of the Red Cross (ICRC), while recognising that it is "primarily the duty and responsibility of a nation to safeguard the health and physical well-being of its own people", knew there would always, especially in times of war, be a "need for voluntary agencies to supplement…the official agencies charged with these responsibilities in every country." To ensure that its mission was widely accepted, it required a body of rules to govern its own activities and those of the involved belligerent parties.
Only one year later, the Swiss government invited the governments of all European countries, as well as the United States, Brazil, and Mexico, to attend an official diplomatic conference. Sixteen countries sent a total of twenty-six delegates to Geneva. The meeting was presided over by General Guillaume Henri Dufour. The conference took place in the Alabama room at Geneva's Hotel de Ville (city hall) on 22 August 1864. The conference adopted the first Geneva Convention "for the Amelioration of the Condition of the Wounded in Armies in the Field". Representatives of 12 states signed the convention:

The First Geneva Convention for the Amelioration of the Condition of the Wounded in Armies in the Field, held on 22 August 1864, is the first of four treaties of the Geneva Conventions. It defines "the basis on which rest the rules of international law for the protection of the victims of armed conflicts."After the first treaty was adopted in 1864, it was significantly revised and replaced in 1906, 1929, and finally 1949. It is inextricably linked to the International Committee of the Red Cross, which is both the instigator for the inception and enforcer of the articles in these conventions.

Nyenschantz (Russian: Ниенша́нц, Nienshants; Swedish: Nyenskans; Finnish: Nevanlinna) was a Swedish fortress at the confluence of the Neva River and Okhta River, the site of present-day Saint Petersburg, Russia. Nyenschantz was built in 1611 to establish Swedish rule in Ingria, which had been annexed from the Tsardom of Russia during the Time of Troubles. The town of Nyen, which formed around Nyenschantz, became a wealthy trading center and a capital of Swedish Ingria during the 17th century. In 1702, Nyenschantz and Nyen were conquered by Russia during the Great Northern War, and the new Russian capital of Saint Petersburg was established by Peter the Great in their place the following year.

In 2020, letters accounted for around 40 percent of the total revenue of PostNord in Sweden.Since 2021, PostNord Sweden has gradually been moving towards mail delivery once every two working days instead of every working day. The change is expected to be completed during 2022. This was made possible by changes to postal regulations issued in 2018.In 2020, the Swedish government initiated a public inquiry to review the possibilities of further changes to postal regulations. Topics to be covered include confidentiality requirements and measures to avoid the distribution of narcotics and weapons through postal services. The financing of country-wide postal services is also being reviewed.

Fort Augustaborg was a Danish fort on the eastern Gold Coast in present-day Ghana, which was located about 15 km east of Fort Christiansborg near present-day Teshie.History
The fort was named for Princess Louise Augusta of Denmark, the fort was constructed in 1787 to combat attacks from the Portuguese Empire. It was also used as a post for the Atlantic slave trade. Five years later, Denmark was the first European nation to abolish the slave trade.On 17 August 1850, the fort was one of five Danish forts purchased by Queen Victoria.After the independence of Ghana in 1957, the fort became owned by the new administration. Along with 32 other forts and castles along Ghana’s coast, Fort Augusaborg is a UNESCO World Heritage Site.

The Cedet, originally Central Department Store (Polish: Centralny Dom Towarowy, CDT) is a Modernist building, originally department store, currently office building, in Warsaw, Poland. It was designed by architects Zbigniew Ihnatowicz and Jerzy Romański and build between 1948 and 1952. Distinct from socialist realism architecture build at the time and proclaimed as aesthetic doctrine in 1949 by communist rule in Poland CDT building aroused controversy. Between 2014 and 2018 it underwent major rebuild by private investor who bought it in 2013, which received unfavourable opinions from architecture community, but was widely acclaimed by the public.Architecture
The building was designed in the popular pre-war 1920s style of modernism. Built as a detached structure formed from three separate blocks, the first, main, block forms the core of the store itself, with the main façade of the building fronting Aleje Jerozolimskie, the second construction operates as a food hall, whilst the third became a small office building attached to the rear of the main store via the restaurant section at ground floor. The main store was previously famous for its high-modernist windows, which were constructed using Polish oak frames and glass panes with an anti-reflective coating - a first for post-war era Polish architecture. The south elevation's main façade was specially designed to carry advertising and for most of its history was adorned with the store's trademark neon lights, arranged in the shape of spirals and supplemented with the vertically stacked letters "CDT", which stood for the store's original name 'Centralny Dom Towarowy' Central Department Store.
Inside the building, communication between floors was ensured with the construction of 6 main escalators and 4 elevators within a central stairwell, these were further supplemented by a multitude of other minor escalators and stairways; this made CDT the second building in Warsaw to use moving-stairway technology. The building has two major emergency exits which lead directly down to Bracka and Krucza streets.
The lobby of the store was originally decorated with terracotta wall tiling and oak flooring whilst the basement floor utilised reinforced concrete with glass and steel fittings; the use of these materials was then expanded to outfit the whole store. In addition to the standard fittings, a number of special pieces of art were commissioned for the interiors of the store, these included both sculpture and paintings, although they were usually of a distinctly modernist or post-modernist style.

Lascaux (English: la-SKOH, US also lah-SKOH; French: Grotte de Lascaux [ɡʁɔt də lasko], "Lascaux Cave") is a network of caves near the village of Montignac, in the department of Dordogne in southwestern France. Over 600 parietal wall paintings cover the interior walls and ceilings of the cave. The paintings represent primarily large animals, typical local contemporary fauna that correspond with the fossil record of the Upper Paleolithic in the area. They are the combined effort of many generations and, with continued debate, the age of the paintings is now usually estimated at around 17,000 years (early Magdalenian). Because of the outstanding prehistoric art in the cave, Lascaux was inducted into the UNESCO World Heritage List in 1979, as an element of the Prehistoric Sites and Decorated Caves of the Vézère Valley.The original caves have been closed to the public since 1963, as their condition was deteriorating, but there are now a number of replicas.

Lascaux II, an exact copy of the Great Hall of the Bulls and the Painted Gallery was displayed at the Grand Palais in Paris, before being displayed from 1983 in the cave's vicinity (about 200 m or 660 ft away from the original cave), a compromise and attempt to present an impression of the paintings' scale and composition for the public without harming the originals. A full range of Lascaux's parietal art is presented a few kilometres from the site at the Centre of Prehistoric Art, Le Parc du Thot, where there are also live animals representing ice-age fauna.The paintings for this site were duplicated with the same type of materials (such as iron oxide, charcoal, and ochre) which were believed to be used 19,000 years ago. Other facsimiles of Lascaux have also been produced over the years.Lascaux III
Lascaux III is a series of five exact reproductions of the cave art (the Nave and Shaft) that, since 2012, have traveled around the world allowing knowledge of Lascaux to be shared far from the original.Lascaux IV
Lascaux IV is a new copy of all the painted areas of the cave that forms part of the International Centre for Parietal Art (Centre International de l'Art Pariétal). Since December 2016 this larger and more accurate replica which integrates digital technology into the display is presented in a new museum built by Snøhetta inside the hill overlooking Montignac.

South Asia
In South Asia, the potato is a very popular traditional staple. In India, the most popular potato dishes are aloo ki sabzi, batata vada, and samosa, which is spicy mashed potato mixed with a small amount of vegetable stuffed in conical dough, and deep-fried. Potatoes are also a major ingredient as fast-food items, such as aloo chaat, where they are deep-fried and served with chutney. In Northern India, alu dum and alu paratha are a favourite part of the diet; the first is a spicy curry of boiled potato, the second is a type of stuffed chapati.
A dish called masala dosa from South India is notable all over India. It is a thin pancake of rice and pulse batter rolled over spicy smashed potato and eaten with sambhar and chutney. Poori in south India, in particular in Tamil Nadu, is almost always taken with smashed potato masal. Other favourite dishes are alu tikki and pakoda items.
Vada pav is a popular vegetarian fast-food dish in Mumbai and other regions in Maharashtra in India.
Aloo posto (a curry with potatoes and poppy seeds) is popular in East India, especially Bengal. Although potatoes are not native to India, it has become a vital part of food all over the country especially North Indian food preparations. In Tamil Nadu this tuber acquired a name based on its appearance, 'urulai-k-kizhangu' (உருளைக் கிழங்கு), meaning cylindrical tuber.
Aloo gosht, potato and meat curry, is one of the popular dishes in South Asia, especially in Pakistan.East Asia
In East Asia, particularly Southeast Asia, rice is by far the predominant starch crop, with potatoes a secondary crop, especially in China and Japan. However, it is used in northern China where rice is not easily grown, with a popular dish being 青椒土豆丝 (qīng jiāo tǔ dòu sī), made with green pepper, vinegar and thin slices of potato. In the winter, roadside sellers in northern China will also sell roasted potatoes. It is also occasionally seen in Korean and Thai cuisines.

The potato is a starchy food, a tuber of the plant Solanum tuberosum and is a root vegetable native to the Americas. The plant is a perennial in the nightshade family Solanaceae.Wild potato species can be found from the southern United States to southern Chile. The potato was originally believed to have been domesticated by Native Americans independently in multiple locations, but later genetic studies traced a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there approximately 7,000–10,000 years ago, from a species in the Solanum brevicaule complex. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Potatoes were introduced to Europe from the Americas by the Spanish in the second half of the 16th century. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice. Following millennia of selective breeding, there are now over 5,000 different types of potatoes. Over 99% of potatoes presently cultivated worldwide descend from varieties that originated in the lowlands of south-central Chile. The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially Northern and Eastern Europe, where per capita production is still the highest in the world, while the most rapid expansion in production during the 21st century was in southern and eastern Asia, with China and India leading the world production of 376 million tonnes, as of 2021.
Like the tomato, the potato is a nightshade in the genus Solanum, and the vegetative and fruiting parts of the potato contain the toxin solanine which is dangerous for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible for human health, but, if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.

Copper is a chemical element with the symbol Cu (from Latin: cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 3500 BC.In the Roman era, copper was mined principally on Cyprus, the origin of the name of the metal, from aes cyprium (metal of Cyprus), later corrupted to cuprum (Latin). Coper (Old English) and copper were derived from this, the later spelling first used around 1530.Commonly encountered compounds are copper(II) salts, which often impart blue or green colors to such minerals as azurite, malachite, and turquoise, and have been used widely and historically as pigments.
Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.
Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the iron-complexed hemoglobin in fish and other vertebrates. In humans, copper is found mainly in the liver, muscle, and bone. The adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight.

Characteristics
Physical
Copper, silver, and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility, and electrical and thermal conductivity. The filled d-shells in these elements contribute little to interatomic interactions, which are dominated by the s-electrons through metallic bonds. Unlike metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This observation explains the low hardness and high ductility of single crystals of copper. At the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress, thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms.The softness of copper partly explains its high electrical conductivity (59.6×106 S/m) and high thermal conductivity, second highest (second only to silver) among pure metals at room temperature. This is because the resistivity to electron transport in metals at room temperature originates primarily from scattering of electrons on thermal vibrations of the lattice, which are relatively weak in a soft metal. The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively.Copper is one of a few metallic elements with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. This is due to the low plasma frequency of the metal, which lies in the red part of the visible spectrum, causing it to absorb the higher-frequency green and blue colors.As with other metals, if copper is put in contact with another metal, galvanic corrosion will occur.

A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement.
Copper is one of the few metals that can occur in nature in a directly usable metallic form (native metals). This led to very early human use in several regions, from c. 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, c. 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create bronze, c. 3500 BC.In the Roman era, copper was mined principally on Cyprus, the origin of the name of the metal, from aes cyprium (metal of Cyprus), later corrupted to cuprum (Latin). Coper (Old English) and copper were derived from this, the later spelling first used around 1530.Commonly encountered compounds are copper(II) salts, which often impart blue or green colors to such minerals as azurite, malachite, and turquoise, and have been used widely and historically as pigments.
Copper used in buildings, usually for roofing, oxidizes to form a green patina of compounds called verdigris. Copper is sometimes used in decorative art, both in its elemental metal form and in compounds as pigments. Copper compounds are used as bacteriostatic agents, fungicides, and wood preservatives.
Copper is essential to all living organisms as a trace dietary mineral because it is a key constituent of the respiratory enzyme complex cytochrome c oxidase. In molluscs and crustaceans, copper is a constituent of the blood pigment hemocyanin, replaced by the iron-complexed hemoglobin in fish and other vertebrates. In humans, copper is found mainly in the liver, muscle, and bone. The adult body contains between 1.4 and 2.1 mg of copper per kilogram of body weight.Ancient and post-classical
In Greece, copper was known by the name chalkos (χαλκός). It was an important resource for the Romans, Greeks and other ancient peoples. In Roman times, it was known as aes Cyprium, aes being the generic Latin term for copper alloys and Cyprium from Cyprus, where much copper was mined. The phrase was simplified to cuprum, hence the English copper. Aphrodite (Venus in Rome) represented copper in mythology and alchemy because of its lustrous beauty and its ancient use in producing mirrors; Cyprus, the source of copper, was sacred to the goddess. The seven heavenly bodies known to the ancients were associated with the seven metals known in antiquity, and Venus was assigned to copper, both because of the connection to the goddess and because Venus was the brightest heavenly body after the Sun and Moon and so corresponded to the most lustrous and desirable metal after gold and silver.Copper was first mined in ancient Britain as early as 2100 BC. Mining at the largest of these mines, the Great Orme, continued into the late Bronze Age. Mining seems to have been largely restricted to supergene ores, which were easier to smelt. The rich copper deposits of Cornwall seem to have been largely untouched, in spite of extensive tin mining in the region, for reasons likely social and political rather than technological.In North America, native copper is known to have been extracted from sites on Isle Royale with primitive stone tools between 800 and 1600 AD. Copper annealing was being performed in the North American city of Cahokia around 1000-1300 AD. There are several exquisite copper plates, known as the Mississippian copper plates that have been found in North America in the area around Cahokia dating from this time period (1000-1300 AD). The copper plates were thought to have been manufactured at Cahokia before ending up elsewhere in the Midwest and southeastern United States like the Wulfing cache and Etowah plates.

Wire and cable
Despite competition from other materials, copper remains the preferred electrical conductor in nearly all categories of electrical wiring except overhead electric power transmission where aluminium is often preferred. Copper wire is used in power generation, power transmission, power distribution, telecommunications, electronics circuitry, and countless types of electrical equipment. Electrical wiring is the most important market for the copper industry. This includes structural power wiring, power distribution cable, appliance wire, communications cable, automotive wire and cable, and magnet wire. Roughly half of all copper mined is used for electrical wire and cable conductors. Many electrical devices rely on copper wiring because of its multitude of inherent beneficial properties, such as its high electrical conductivity, tensile strength, ductility, creep (deformation) resistance, corrosion resistance, low thermal expansion, high thermal conductivity, ease of soldering, malleability, and ease of installation.
For a short period from the late 1960s to the late 1970s, copper wiring was replaced by aluminium wiring in many housing construction projects in America. The new wiring was implicated in a number of house fires and the industry returned to copper.

Gold is a chemical element with the symbol Au (from Latin aurum 'gold') and atomic number 79. This makes it one of the higher–atomic-number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions.
Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as in electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides).
Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is insoluble in nitric acid alone, which dissolves silver and base metals, a property long used to refine gold and confirm the presence of gold in metallic substances, giving rise to the term 'acid test'. Gold dissolves in alkaline solutions of cyanide, which are used in mining and electroplating. Gold also dissolves in mercury, forming amalgam alloys, and as the gold acts simply as a solute, this is not a chemical reaction.
A relatively rare element, gold is a precious metal that has been used for coinage, jewelry, and other arts throughout recorded history. In the past, a gold standard was often implemented as a monetary policy. Gold coins ceased to be minted as a circulating currency in the 1930s, and the world gold standard was abandoned for a fiat currency system after the Nixon shock measures of 1971.
In 2020, the world's largest gold producer was China, followed by Russia and Australia. A total of around 201,296 tonnes of gold exists above ground, as of 2020. This is equal to a cube with each side measuring roughly 21.7 meters (71 ft). The world consumption of new gold produced is about 50% in jewelry, 40% in investments and 10% in industry. Gold's high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity have led to its continued use in corrosion-resistant electrical connectors in all types of computerized devices (its chief industrial use). Gold is also used in infrared shielding, production of colored glass, gold leafing, and tooth restoration. Certain gold salts are still used as anti-inflammatories in medicine.

Magnetic properties
Below its Curie point of 770 °C (1,420 °F; 1,040 K), α-iron changes from paramagnetic to ferromagnetic: the spins of the two unpaired electrons in each atom generally align with the spins of its neighbors, creating an overall magnetic field. This happens because the orbitals of those two electrons (dz2 and dx2 −. y2) do not point toward neighboring atoms in the lattice, and therefore are not involved in metallic bonding.In the absence of an external source of magnetic field, the atoms get spontaneously partitioned into magnetic domains, about 10 micrometers across, such that the atoms in each domain have parallel spins, but some domains have other orientations. Thus a macroscopic piece of iron will have a nearly zero overall magnetic field.
Application of an external magnetic field causes the domains that are magnetized in the same general direction to grow at the expense of adjacent ones that point in other directions, reinforcing the external field. This effect is exploited in devices that need to channel magnetic fields to fulfill design function, such as electrical transformers, magnetic recording heads, and electric motors. Impurities, lattice defects, or grain and particle boundaries can "pin" the domains in the new positions, so that the effect persists even after the external field is removed – thus turning the iron object into a (permanent) magnet.Similar behavior is exhibited by some iron compounds, such as the ferrites including the mineral magnetite, a crystalline form of the mixed iron(II,III) oxide Fe3O4 (although the atomic-scale mechanism, ferrimagnetism, is somewhat different). Pieces of magnetite with natural permanent magnetization (lodestones) provided the earliest compasses for navigation. Particles of magnetite were extensively used in magnetic recording media such as core memories, magnetic tapes, floppies, and disks, until they were replaced by cobalt-based materials.

Chemistry
Silver is a rather unreactive metal. This is because its filled 4d shell is not very effective in shielding the electrostatic forces of attraction from the nucleus to the outermost 5s electron, and hence silver is near the bottom of the electrochemical series (E0(Ag+/Ag) = +0.799 V). In group 11, silver has the lowest first ionization energy (showing the instability of the 5s orbital), but has higher second and third ionization energies than copper and gold (showing the stability of the 4d orbitals), so that the chemistry of silver is predominantly that of the +1 oxidation state, reflecting the increasingly limited range of oxidation states along the transition series as the d-orbitals fill and stabilize. Unlike copper, for which the larger hydration energy of Cu2+ as compared to Cu+ is the reason why the former is the more stable in aqueous solution and solids despite lacking the stable filled d-subshell of the latter, with silver this effect is swamped by its larger second ionisation energy. Hence, Ag+ is the stable species in aqueous solution and solids, with Ag2+ being much less stable as it oxidizes water.Most silver compounds have significant covalent character due to the small size and high first ionization energy (730.8 kJ/mol) of silver. Furthermore, silver's Pauling electronegativity of 1.93 is higher than that of lead (1.87), and its electron affinity of 125.6 kJ/mol is much higher than that of hydrogen (72.8 kJ/mol) and not much less than that of oxygen (141.0 kJ/mol). Due to its full d-subshell, silver in its main +1 oxidation state exhibits relatively few properties of the transition metals proper from groups 4 to 10, forming rather unstable organometallic compounds, forming linear complexes showing very low coordination numbers like 2, and forming an amphoteric oxide as well as Zintl phases like the post-transition metals. Unlike the preceding transition metals, the +1 oxidation state of silver is stable even in the absence of π-acceptor ligands.Silver does not react with air, even at red heat, and thus was considered by alchemists as a noble metal, along with gold. Its reactivity is intermediate between that of copper (which forms copper(I) oxide when heated in air to red heat) and gold. Like copper, silver reacts with sulfur and its compounds; in their presence, silver tarnishes in air to form the black silver sulfide (copper forms the green sulfate instead, while gold does not react). Unlike copper, silver will not react with the halogens, with the exception of fluorine gas, with which it forms the difluoride. While silver is not attacked by non-oxidizing acids, the metal dissolves readily in hot concentrated sulfuric acid, as well as dilute or concentrated nitric acid. In the presence of air, and especially in the presence of hydrogen peroxide, silver dissolves readily in aqueous solutions of cyanide.The three main forms of deterioration in historical silver artifacts are tarnishing, formation of silver chloride due to long-term immersion in salt water, as well as reaction with nitrate ions or oxygen. Fresh silver chloride is pale yellow, becoming purplish on exposure to light; it projects slightly from the surface of the artifact or coin. The precipitation of copper in ancient silver can be used to date artifacts, as copper is nearly always a constituent of silver alloys.Silver metal is attacked by strong oxidizers such as potassium permanganate (KMnO4) and potassium dichromate (K2Cr2O7), and in the presence of potassium bromide (KBr). These compounds are used in photography to bleach silver images, converting them to silver bromide that can either be fixed with thiosulfate or redeveloped to intensify the original image. Silver forms cyanide complexes (silver cyanide) that are soluble in water in the presence of an excess of cyanide ions. Silver cyanide solutions are used in electroplating of silver.The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO3); +2 (highly oxidising; for example, silver(II) fluoride, AgF2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III), KAgF4). The +3 state requires very strong oxidising agents to attain, such as fluorine or peroxodisulfate, and some silver(III) compounds react with atmospheric moisture and attack glass. Indeed, silver(III) fluoride is usually obtained by reacting silver or silver monofluoride with the strongest known oxidizing agent, krypton difluoride.History
Silver was one of the seven metals of antiquity that were known to prehistoric humans and whose discovery is thus lost to history. In particular, the three metals of group 11, copper, silver, and gold, occur in the elemental form in nature and were probably used as the first primitive forms of money as opposed to simple bartering. However, unlike copper, silver did not lead to the growth of metallurgy on account of its low structural strength, and was more often used ornamentally or as money. Since silver is more reactive than gold, supplies of native silver were much more limited than those of gold. For example, silver was more expensive than gold in Egypt until around the fifteenth century BC: the Egyptians are thought to have separated gold from silver by heating the metals with salt, and then reducing the silver chloride produced to the metal.The situation changed with the discovery of cupellation, a technique that allowed silver metal to be extracted from its ores. While slag heaps found in Asia Minor and on the islands of the Aegean Sea indicate that silver was being separated from lead as early as the 4th millennium BC, and one of the earliest silver extraction centres in Europe was Sardinia in the early Chalcolithic period, these techniques did not spread widely until later,
when it spread throughout the region and beyond. The origins of silver production in India, China, and Japan were almost certainly equally ancient, but are not well-documented due to their great age.

Silver is a chemical element with the symbol Ag (from Latin argentum 'silver', derived from the Proto-Indo-European h₂erǵ 'shiny, white') and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc refining.
Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of the seven metals of antiquity, silver has had an enduring role in most human cultures.
Other than in currency and as an investment medium (coins and bullion), silver is used in solar panels, water filtration, jewellery, ornaments, high-value tableware and utensils (hence the term "silverware"), in electrical contacts and conductors, in specialized mirrors, window coatings, in catalysis of chemical reactions, as a colorant in stained glass, and in specialized confectionery. Its compounds are used in photographic and X-ray film. Dilute solutions of silver nitrate and other silver compounds are used as disinfectants and microbiocides (oligodynamic effect), added to bandages, wound-dressings, catheters, and other medical instruments.

"Miniskirt",
"discoverer or inventor",
"Mary Quant"
] |
A miniskirt (sometimes hyphenated as mini-skirt, separated as mini skirt, or sometimes shortened to simply mini) is a skirt with its hemline well above the knees, generally at mid-thigh level, normally no longer than 10 cm (4 in) below the buttocks; and a dress with such a hemline is called a minidress or a miniskirt dress. A micro-miniskirt or microskirt is a miniskirt with its hemline at the upper thigh, at or just below crotch or underwear level.
Short skirts have existed for a long time before they made it into mainstream fashion, though they were generally not called "mini" until they became a fashion trend in the 1960s. Instances of clothing resembling miniskirts have been identified by archaeologists and historians as far back as c. 1390–1370 BC. In the early 20th century, the dancer Josephine Baker's banana skirt that she wore for her mid-1920s performances in the Folies Bergère was subsequently likened to a miniskirt. Extremely short skirts became a staple of 20th-century science fiction, particularly in 1940s pulp artwork, such as that by Earle K. Bergey, who depicted futuristic women in a "stereotyped combination" of metallic miniskirt, bra and boots.
Hemlines were just above the knee in 1961, and gradually climbed upward over the next few years. By 1966, some designs had the hem at the upper thigh. Stockings with suspenders (garters) were not considered practical with miniskirts and were replaced with coloured tights. The popular acceptance of miniskirts peaked in the "Swinging London" of the 1960s, and has continued to be commonplace, particularly among younger women and teenage girls. Before that time, short skirts were only seen in sport and dance clothing, such as skirts worn by female tennis players, figure skaters, cheerleaders, and dancers.
Several designers have been credited with the invention of the 1960s miniskirt, most significantly the London-based designer Mary Quant and the Parisian André Courrèges.1960s
The manager of an unnamed shop in London's Oxford Street began experimenting in 1960 with skirt hemlines an inch above the knees of window mannequins, and noted how positively his customers responded. In August 1961, Life published a photograph of two Seattle students at the University of Hawaiʻi wearing above-the-knee garments called "kookie-muus" (an abbreviated version of the traditionally concealing muumuu), and noted a "current teen-age fad for short skirts" that was pushing hemlines well above the knee. The article also showed young fashionable girls in San Francisco wearing hemlines "just above the kneecap" and students at Vanderbilt University wearing "knee ticklers" ending three inches above their knee to play golf in, while the caption commented that such short skirts were selling well in the South, and that "some Atlanta girls" were cutting old skirts to "thigh high" lengths.Extremely short skirts, some as much as eight inches above the knee, were observed in Britain in the summer of 1962. The young women who wore these short skirts were called "Ya-Ya girls", a term derived from "yeah, yeah" which was a popular catcall at the time. One retailer noted that the fashion for layered net crinoline petticoats raised the hems of short skirts even higher. The earliest known reference to the miniskirt is in a humorous 1962 article datelined Mexico City and describing the "mini-skirt" or "Ya-Ya" as a controversial item of clothing that was the latest thing on the production line there. The article characterised the miniskirt as stopping eight inches above the knee. It referred to a writing by a psychiatrist, whose name it did not provide, who had argued that the miniskirt was a youthful protest of international threats to peace. Much of the article described the reactions of men, who were said to favour the fashion on young women to whom they were unrelated, but to oppose it on their own wives and fiancées.Only a very few of the avant-garde, almost entirely in the UK, wore such lengths in the beginning years of the decade, however. The standard hemline for public and designer garments in the early sixties was mid-knee, just covering the knee. It would gradually climb upward over the next few years, fully baring the knees of mainstream models in 1964, when both André Courrèges and Mary Quant showed above-the-knee lengths. The following year, skirts continued to rise as British miniskirts were officially introduced to the US in a New York show whose models' thigh-high skirts stopped traffic. By 1966, many designs had the hem at the upper thigh. Stockings with suspenders (American English: "garters") were not considered practical with miniskirts and were replaced with coloured tights. Legs could also be covered with knee-high socks or various heights of boots, lower-calf height in 1964–65, knee-heights throughout the period, over-the-knee and thigh-high boots more 1967–69, and even boot-hose or body boots, tights incorporating a shoe sole and heel to form a waist-high boot, often in stretch vinyl. Sandal straps or laces might crisscross or otherwise rise up the leg, even as high as the thigh, and body paints were offered for a time to add colour to the leg in more individualised ways than wearing tights. Towards the end of the 1960s, an even shorter version, called the microskirt or micro-mini, emerged.

Benefits and criticisms
Financial cost
Street width, or right of way (ROW), influences the amount of land that is devoted to streets, which becomes unavailable for development and therefore represents an opportunity cost. The wider the street, the higher the opportunity cost. Street width is determined by circulation and aesthetic considerations and is not dependent on the pattern configuration. Any configuration can have wide or narrow streets.
Street length influences proportionately the number of street components that have to be constructed such as pavement, curbs and sidewalks, storm sewers and drains, light poles, and trees. The street length of a given area of development depends on the frequency at which streets occur which in turn depends on the length and width of a block. The higher the frequency of streets the longer is their total length. The smaller the block dimensions the higher the frequency of the streets. As the frequency of street increases so does the number of intersections. Intersections normally cost more than straight street length because they are labour-intensive and require street and traffic signage.
Pavement width influences the cost by affecting the amount of materials and labour required to provide a finished road surface. Pavement width is generally based on traffic engineering considerations and is not dependent on pattern configuration. As with the street width, any pattern can have wide or narrow pavements.
Of all three factors that affect cost, street width, street length and pavement width, only street length is pattern dependent. An objective cost comparison would, therefore, rely on this variable with the full understanding that the other variables, though optional, can play a role.
Traditional orthogonal grid patterns generally have greater street frequencies than discontinuous patterns. For example, Portland's block is 200 feet × 200 feet while Miletus' is half that size and Timgad's half again (see diagram). Houston, Sacramento and Barcelona are progressively bigger reaching up to four times the area of Portland's block. New York's 1811 plan (see above) has blocks of 200 feet (61 m). in width and variable lengths ranging from about 500 feet (150 m) to 900 feet (270 m) feet. The corresponding frequency of streets for each of these block sizes affects the street length.
A simple example of a grid street pattern (see diagram) illustrates the progressive reduction in total street length (the sum of all individual street lengths) and the corresponding increase in block length. For a corresponding reduction of one, two, three and four streets within this 40-acre (16 ha) parcel, the street length is reduced from an original total of 12,600 feet (3,800 m) to 7,800 feet (2,400 m) linear feet, a 39% reduction. Simultaneously, block lengths increase from 200 × 200 feet to 1240 × 200 feet. When all five blocks have reached the ultimate size of 1,240 feet (380 m) four street lengths out of total eight have been eliminated. Block lengths of 1,000 feet (300 m) or larger rarely appear in grid plans and are not recommended as they hinder pedestrian movement (Pedestrianism, below). From the pedestrian perspective, the smaller the block is, the easier the navigation and the more direct the route. Consequently, the finer grids are preferred.
Patterns that incorporate discontinuous street types such as crescents and culs-de-sac have not, in general, regarded pedestrian movement as a priority and, consequently, have produced blocks that are usually in the 1,000 feet (300 m) range and often exceed it. As a result, street frequency drops and so does the total street length and, therefore, the cost. In general, it is not the street pattern per se that affects costs but the frequency of streets that it either necessitates or purposely incorporates.
An inherent advantage of the orthogonal geometry of a proper grid is its tendency to yield regular lots in well-packed sequences. This maximizes the use of the land of the block; it does not, however, affect street frequency. Any frequency of orthogonal streets produces the same packing effect. Orthogonal geometry also minimizes disputes over lot boundaries and maximizes the number of lots that could front a given street. John Randal said Manhattan's grid plan facilitated "buying, selling and improving real estate".Another important aspect of street grids and the use of rectilinear blocks is that traffic flows of either pedestrians, cars, or both, only cross at right angles. This is an important traffic safety feature, since no one entering the intersection needs to look over their shoulder to see oncoming traffic. Any time traffic flows meet at an acute angle, someone cannot see traffic approaching them. The grid is thus a geometric response to our human physiology. It is very likely the original purpose of grid layouts comes from the Athenian Agora. Before the grid organization, markets were laid out randomly in a field with traffic approaches at odd angles. This caused carts and wagons to turn over due to frequent collisions. Laying out the market stalls into regularized rows at right angles solved this problem and was later built into the Athenian Agora and copied ever since.

"Go (game)",
"subclass of",
"board game"
] |
Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.The playing pieces are called stones. One player uses the white stones and the other black. The players take turns placing the stones on the vacant intersections (points) on a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is captured. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second). Games may also be terminated by resignation.
The standard Go board has a 19×19 grid of lines, containing 361 points. Beginners often play on smaller 9×9 and 13×13 boards, and archaeological evidence shows that the game was played in earlier centuries on a board with a 17×17 grid. However, boards with a 19×19 grid had become standard by the time the game reached Korea in the 5th century CE and Japan in the 7th century CE.Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan (c. 4th century BCE).Despite its relatively simple rules, Go is extremely complex. Compared to chess, Go has both a larger board with more scope for play and longer games and, on average, many more alternatives to consider per move. The number of legal board positions in Go has been calculated to be approximately 2.1×10170, which is far greater than the number of atoms in the observable universe, estimated to be of the order of 1080.

The reasons why computer programs had not played Go at the professional dan level prior to 2016 include:
The number of spaces on the board is much larger (over five times the number of spaces on a chess board—361 vs. 64). On most turns there are many more possible moves in Go than in chess. Throughout most of the game, the number of legal moves stays at around 150–250 per turn, and rarely falls below 100 (in chess, the average number of moves is 37). Because an exhaustive computer program for Go must calculate and compare every possible legal move in each ply (player turn), its ability to calculate the best plays is sharply reduced when there are a large number of possible moves. Most computer game algorithms, such as those for chess, compute several moves in advance. Given an average of 200 available moves through most of the game, for a computer to calculate its next move by exhaustively anticipating the next four moves of each possible play (two of its own and two of its opponent's), it would have to consider more than 320 billion (3.2×1011) possible combinations. To exhaustively calculate the next eight moves, would require computing 512 quintillion (5.12×1020) possible combinations. As of March 2014, the most powerful supercomputer in the world, NUDT's "Tianhe-2", can sustain 33.86 petaflops. At this rate, even given an exceedingly low estimate of 10 operations required to assess the value of one play of a stone, Tianhe-2 would require four hours to assess all possible combinations of the next eight moves in order to make a single play.
The placement of a single stone in the initial phase can affect the play of the game a hundred or more moves later. A computer would have to predict this influence, and it would be unworkable to attempt to exhaustively analyze the next hundred moves.
In capture-based games (such as chess), a position can often be evaluated relatively easily, such as by calculating who has a material advantage or more active pieces. In Go, there is often no easy way to evaluate a position. However a 6-kyu human can evaluate a position at a glance, to see which player has more territory, and even beginners can estimate the score within 10 points, given time to count it. The number of stones on the board (material advantage) is only a weak indicator of the strength of a position, and a territorial advantage (more empty points surrounded) for one player might be compensated by the opponent's strong positions and influence all over the board. Normally a 3-dan can easily judge most of these positions.As an illustration, the greatest handicap normally given to a weaker opponent is 9 stones. It was not until August 2008 that a computer won a game against a professional level player at this handicap. It was the Mogo program, which scored this first victory in an exhibition game played during the US Go Congress. By 2013, a win at the professional level of play was accomplished with a four-stone advantage. In October 2015, Google DeepMind's program AlphaGo beat Fan Hui, the European Go champion and a 2 dan (out of 9 dan possible) professional, five times out of five with no handicap on a full size 19×19 board. AlphaGo used a fundamentally different paradigm than earlier Go programs; it included very little direct instruction, and mostly used deep learning where AlphaGo played itself in hundreds of millions of games such that it could measure positions more intuitively. In March 2016, Google next challenged Lee Sedol, a 9 dan considered the top player in the world in the early 21st century, to a five-game match. Leading up to the game, Lee Sedol and other top professionals were confident that he would win; however, AlphaGo defeated Lee in four of the five games. After having already lost the series by the third game, Lee won the fourth game, describing his win as "invaluable". In May 2017, AlphaGo beat Ke Jie, who at the time continuously held the world No. 1 ranking for two years, winning each game in a three-game match during the Future of Go Summit.In October 2017, DeepMind announced a significantly stronger version called AlphaGo Zero which beat the previous version by 100 games to 0.In February 2023, Kellin Pelrine, an amateur American Go player, won 14 out of 15 games against a top-ranked AI system in a significant victory over artificial intelligence. Pelrine took advantage of a previously unknown flaw in the Go computer program, which had been identified by another computer. He exploited this weakness by slowly encircling the opponent's stones and distracting the AI with moves in other parts of the board. The tactics used by Pelrine have highlighted a fundamental flaw in the deep learning systems that underpin many of today's advanced AI. Although the AI systems can "understand" specific situations, they lack the ability to generalize in a way that humans find easy.

History
Origin in China
The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan (c. 4th century BCE), referring to a historical event of 548 BCE. It is also mentioned in Book XVII of the Analects of Confucius and in two books written by Mencius (c. 3rd century BCE). In all of these works, the game is referred to as yì (弈). Today, in China, it is known as weiqi (simplified Chinese: 围棋; traditional Chinese: 圍棋; pinyin: wéiqí; Wade–Giles: wei ch'i), lit. 'encirclement board game'.
Go was originally played on a 17×17 line grid, but a 19×19 grid became standard by the time of the Tang Dynasty (618–907 CE). Legends trace the origin of the game to the mythical Chinese emperor Yao (2337–2258 BCE), who was said to have had his counselor Shun design it for his unruly son, Danzhu, to favorably influence him. Other theories suggest that the game was derived from Chinese tribal warlords and generals, who used pieces of stone to map out attacking positions.In China, Go was considered one of the four cultivated arts of the Chinese scholar gentleman, along with calligraphy, painting and playing the musical instrument guqin In ancient times the rules of go were passed on verbally, rather than being written down.

"Go (game)",
"subclass of",
"two-player game"
] |
Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia.The playing pieces are called stones. One player uses the white stones and the other black. The players take turns placing the stones on the vacant intersections (points) on a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is captured. The game proceeds until neither player wishes to make another move. When a game concludes, the winner is determined by counting each player's surrounded territory along with captured stones and komi (points added to the score of the player with the white stones as compensation for playing second). Games may also be terminated by resignation.
The standard Go board has a 19×19 grid of lines, containing 361 points. Beginners often play on smaller 9×9 and 13×13 boards, and archaeological evidence shows that the game was played in earlier centuries on a board with a 17×17 grid. However, boards with a 19×19 grid had become standard by the time the game reached Korea in the 5th century CE and Japan in the 7th century CE.Go was considered one of the four essential arts of the cultured aristocratic Chinese scholars in antiquity. The earliest written reference to the game is generally recognized as the historical annal Zuo Zhuan (c. 4th century BCE).Despite its relatively simple rules, Go is extremely complex. Compared to chess, Go has both a larger board with more scope for play and longer games and, on average, many more alternatives to consider per move. The number of legal board positions in Go has been calculated to be approximately 2.1×10170, which is far greater than the number of atoms in the observable universe, estimated to be of the order of 1080.

Equipment
It is possible to play Go with a simple paper board and coins, plastic tokens, or white beans and coffee beans for the stones; or even by drawing the stones on the board and erasing them when captured. More popular midrange equipment includes cardstock, a laminated particle board, or wood boards with stones of plastic or glass. More expensive traditional materials are still used by many players. The most expensive Go sets have black stones carved from slate and white stones carved from translucent white shells, played on boards carved in a single piece from the trunk of a tree.

Signs and symptoms
Early symptoms are malaise and lethargy. After one to three months, patients develop shortness of breath and bone pain. Myalgias may occur because of reduced carnitine production. Other symptoms include skin changes with roughness, easy bruising and petechiae, gum disease, loosening of teeth, poor wound healing, and emotional changes (which may appear before any physical changes). Dry mouth and dry eyes similar to Sjögren's syndrome may occur. In the late stages, jaundice, generalised edema, oliguria, neuropathy, fever, convulsions, and eventual death are frequently seen.Cause
Scurvy, including subclinical scurvy, is caused by a deficiency of dietary vitamin C since humans are unable to metabolically synthesize vitamin C. Provided the diet contains sufficient vitamin C, the lack of working L-gulonolactone oxidase (GULO) enzyme has no significance, and in modern Western societies, scurvy is rarely present in adults, although infants and elderly people are affected. Virtually all commercially available baby formulas contain added vitamin C, preventing infantile scurvy. Human breast milk contains sufficient vitamin C, if the mother has an adequate intake. Commercial milk is pasteurized, a heating process that destroys the natural vitamin C content of the milk.Scurvy is one of the accompanying diseases of malnutrition (other such micronutrient deficiencies are beriberi and pellagra) and thus is still widespread in areas of the world depending on external food aid.
Although rare, there are also documented cases of scurvy due to poor dietary choices by people living in industrialized nations.

"Metonic cycle",

The Metonic cycle or enneadecaeteris (from Ancient Greek: ἐννεακαιδεκαετηρίς, from ἐννεακαίδεκα, "nineteen") is a period of almost exactly 19 years after which the lunar phases recur at the same time of the year. The recurrence is not perfect, and by precise observation the Metonic cycle defined as 235 synodic months is just 2 hours, 4 minutes and 58 seconds longer than 19 tropical years. Meton of Athens, in the 5th century BC, judged the cycle to be a whole number of days, 6,940. Using these whole numbers facilitates the construction of a lunisolar calendar.
A tropical year is longer than 12 lunar months and shorter than 13 of them. The arithmetic identity 12×12 + 7×13 = 235 shows that a combination of 12 "short" years (12 months) and 7 "long" years (13 months) will be almost exactly equal to 19 solar years.

"Halley's Comet",
"named after",
"Edmond Halley"
] |
Halley's Comet, Comet Halley, or sometimes simply Halley, officially designated 1P/Halley, is a short-period comet visible from Earth every 75–79 years. Halley is the only known short-period comet that is regularly visible to the naked eye from Earth, and thus the only naked-eye comet that can appear twice in a human lifetime. It last appeared in the inner parts of the Solar System in 1986 and will next appear in mid-2061.
Halley's periodic returns to the inner Solar System have been observed and recorded by astronomers around the world since at least 240 BC. But it was not until 1705 that the English astronomer Edmond Halley understood that these appearances were re-appearances of the same comet. As a result of this discovery, the comet is named after Edmond Halley.During its 1986 visit to the inner Solar System, Halley's Comet became the first comet to be observed in detail by spacecraft, providing the first observational data on the structure of a comet nucleus and the mechanism of coma and tail formation. These observations supported a number of longstanding hypotheses about comet construction, particularly Fred Whipple's "dirty snowball" model, which correctly predicted that Halley would be composed of a mixture of volatile ices—such as water, carbon dioxide, ammonia, and dust. The missions also provided data that substantially reformed and reconfigured these ideas; for instance, it is now understood that the surface of Halley is largely composed of dusty, non-volatile materials, and that only a small portion of it is icy.Computation of orbit
Halley was the first comet to be recognized as periodic. Until the Renaissance, the philosophical consensus on the nature of comets, promoted by Aristotle, was that they were disturbances in Earth's atmosphere. This idea was disproved in 1577 by Tycho Brahe, who used parallax measurements to show that comets must lie beyond the Moon. Many were still unconvinced that comets orbited the Sun, and assumed instead that they must follow straight paths through the Solar System.In 1687, Sir Isaac Newton published his Philosophiæ Naturalis Principia Mathematica, in which he outlined his laws of gravity and motion. His work on comets was decidedly incomplete. Although he had suspected that two comets that had appeared in succession in 1680 and 1681 were the same comet before and after passing behind the Sun (he was later found to be correct; see Newton's Comet), he was unable to completely reconcile comets into his model.
Ultimately, it was Newton's friend, editor and publisher, Edmond Halley, who, in his 1705 Synopsis of the Astronomy of Comets, used Newton's new laws to calculate the gravitational effects of Jupiter and Saturn on cometary orbits. Having compiled a list of 24 comet observations, he calculated that the orbital elements of a second comet that had appeared in 1682 were nearly the same as those of two comets that had appeared in 1531 (observed by Petrus Apianus) and 1607 (observed by Johannes Kepler). Halley thus concluded that all three comets were, in fact, the same object returning about every 76 years, a period that has since been found to vary between 74 and 79 years. After a rough estimate of the perturbations the comet would sustain from the gravitational attraction of the planets, he predicted its return for 1758. While he had personally observed the comet around perihelion in September 1682, Halley died in 1742 before he could observe its predicted return.Halley's prediction of the comet's return proved to be correct, although it was not seen until 25 December 1758, by Johann Georg Palitzsch, a German farmer and amateur astronomer. It did not pass through its perihelion until 13 March 1759, the attraction of Jupiter and Saturn having caused a retardation of 618 days. This effect was computed before its return (with a one-month error to 13 April) by a team of three French mathematicians, Alexis Clairaut, Joseph Lalande, and Nicole-Reine Lepaute. The confirmation of the comet's return was the first time anything other than planets had been shown to orbit the Sun. It was also one of the earliest successful tests of Newtonian physics, and a clear demonstration of its explanatory power. The comet was first named in Halley's honour by French astronomer Nicolas-Louis de Lacaille in 1759.Some scholars have proposed that first-century Mesopotamian astronomers already had recognized Halley's Comet as periodic. This theory notes a passage in the Babylonian Talmud, tractate Horayot that refers to "a star which appears once in seventy years that makes the captains of the ships err."Researchers in 1981 attempting to calculate the past orbits of Halley by numerical integration starting from accurate observations in the seventeenth and eighteenth centuries could not produce accurate results further back than 837 owing to a close approach to Earth in that year. It was necessary to use ancient Chinese comet observations to constrain their calculations.

The chicken or the egg causality dilemma is commonly stated as the question, "which came first: the chicken or the egg?" The dilemma stems from the observation that all chickens hatch from eggs and all chicken eggs are laid by chickens. "Chicken-and-egg" is a metaphoric adjective describing situations where it is not clear which of two events should be considered the cause and which should be considered the effect, to express a scenario of infinite regress, or to express the difficulty of sequencing actions where each seems to depend on others being done first. Plutarch posed the question as a philosophical matter in his essay "The Symposiacs", written in the 1st century CE.

"Keyboard instrument",

] |
A keyboard instrument is a musical instrument played using a keyboard, a row of levers that are pressed by the fingers. The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.Today, the term keyboard often refers to keyboard-style synthesizers. Under the fingers of a sensitive performer, the keyboard may also be used to control dynamics, phrasing, shading, articulation, and other elements of expression—depending on the design and inherent capabilities of the instrument.Another important use of the word keyboard is in historical musicology, where it means an instrument whose identity cannot be firmly established. Particularly in the 18th century, the harpsichord, the clavichord, and the early piano competed, and the same piece might be played on more than one. Hence, in a phrase such as "Mozart excelled as a keyboard player," the word keyboard is typically all-inclusive.
The term keyboard classifies instruments based on how the performer plays the instrument, and not on how the sound is produced. Categories of keyboard instruments include the following families (of which this is only a partial list):aerophones (pipe organ, pump organ, accordion);
idiophones (celesta, carillon, glasschord);
chordophones:
plucked string instruments (harpsichord, tangent piano, lautenwerck);
bowed string instruments (hurdy-gurdy, bowed clavier);
struck string instruments (clavichord, piano);
electrophones (electric and electronic organs, synthesizers, mellotron).

"Claw of Archimedes",

"Archimedes"
] |
The Claw of Archimedes (Ancient Greek: Ἁρπάγη, romanized: harpágē, lit. 'snatcher'; also known as the iron hand) was an ancient weapon devised by Archimedes to defend the seaward portion of Syracuse's city wall against amphibious assault. Although its exact nature is unclear, the accounts of ancient historians seem to describe it as a sort of crane equipped with a grappling hook that was able to drop an attacking ship partly down in to the water, then either cause the ship to capsize or suddenly drop it. It was dropped onto enemy ships, which would then swing on to defensive forces and destroy them.
These machines featured prominently during the Second Punic War in 214 BC, when the Roman Republic attacked Syracuse with a fleet of 60 quinqueremes under Marcus Claudius Marcellus. When the Roman fleet approached the city walls under cover of darkness, the machines were deployed, sinking many ships and throwing the attack into confusion. Historians such as Livy attributed heavy Roman losses to these machines, together with catapults also devised by Archimedes.
The plausibility of this invention was tested in 1999 in the BBC series Secrets of the Ancients and again in early 2005 in the Discovery Channel series Superweapons of the Ancient World. The producers of Superweapons brought together a group of engineers tasked with conceiving and implementing a design that was realistic, given what is known about Archimedes. Within seven days they were able to test their creation, and they did succeed in tipping over a model of a Roman ship so that it would sink. While this does not prove the existence of the Claw, it suggests that it would have been possible.

The Beehive Cluster (also known as Praesepe (Latin for "manger" or "crib"), M44, NGC 2632, or Cr 189), is an open cluster in the constellation Cancer. One of the nearest open clusters to Earth, it contains a larger population of stars than other nearby bright open clusters holding around 1,000 stars. Under dark skies, the Beehive Cluster looks like a small nebulous object to the naked eye, and has been known since ancient times. Classical astronomer Ptolemy described it as a "nebulous mass in the breast of Cancer". It was among the first objects that Galileo studied with his
telescope.Age and proper motion coincide with those of the Hyades, suggesting they may share similar origins. Both clusters also contain red giants and white dwarfs, which represent later stages of stellar evolution, along with many main sequence stars.
Distance to M44 is often cited to be between 160 and 187 parsecs (520–610 light years), but the revised Hipparcos parallaxes (2009) for Praesepe members and the latest infrared color-magnitude diagram favors an analogous distance of 182 pc. There are better age estimates of around 600 million years (compared to about 625 million years for the Hyades). The diameter of the bright inner cluster core is about 7.0 parsecs (23 light years).At 1.5° across, the cluster easily fits within the field of view of binoculars or low-powered small telescopes. Regulus, Castor, and Pollux are guide stars.

Etymology
The word paper is etymologically derived from Latin papyrus, which comes from the Greek πᾰ́πῡρος (pápūros), the word for the Cyperus papyrus plant. Papyrus is a thick, paper-like material produced from the pith of the Cyperus papyrus plant, which was used in ancient Egypt and other Mediterranean cultures for writing before the introduction of paper. Although the word paper is etymologically derived from papyrus, the two are produced very differently and the development of the first is distinct from the development of the second. Papyrus is a lamination of natural plant fibre, while paper is manufactured from fibres whose properties have been changed by maceration.

Paper is a thin sheet material produced by mechanically or chemically processing cellulose fibres derived from wood, rags, grasses or other vegetable sources in water, draining the water through fine mesh leaving the fibre evenly distributed on the surface, followed by pressing and drying. Although paper was originally made in single sheets by hand, almost all is now made on large machines—some making reels 10 metres wide, running at 2,000 metres per minute and up to 600,000 tonnes a year. It is a versatile material with many uses, including printing, painting, graphics, signage, design, packaging, decorating, writing, and cleaning. It may also be used as filter paper, wallpaper, book endpaper, conservation paper, laminated worktops, toilet tissue, or currency and security paper, or in a number of industrial and construction processes.
The papermaking process developed in east Asia, probably China, at least as early as 105 CE, by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BCE in China. The modern pulp and paper industry is global, with China leading its production and the United States following.Etymology
