Hans Benndorf (December 13, 1870 – February 11, 1953) was an Austrian physicist born in Zurich, and died in Graz. He made several contributions in the field of seismology and in his research of atmospheric electricity. He was the son of archaeologist Otto Benndorf (1838–1907) and the grandson of physiologist Rudolf Wagner (1805–1864). In 1895 he earned his doctorate from the University of Vienna, and subsequently became an assistant to Franz Serafin Exner (1849–1926). In 1904 be became an associate professor of meteorology at the University of Graz. In 1910 he replaced Leopold Pfaundler (1839–1920) as professor of physics, a position he kept until 1936 (forced retirement). In 1945 he resumed his duties in physics at Graz. In 1927 he was elected as a full member of the Austrian Academy of Sciences, and from 1932 to 1934 was university rector. From 1924 he worked closely with geophysicistAlfred Wegener (1880–1930) at Graz, also maintaining professional ties with physicist Victor Franz Hess (1883–1964) and climatologist Victor Conrad (1876–1962) during his career. With Hess he co-authored a comprehensive treatise on atmospheric electricity (1928). In 1907 he founded a seismological observatory at the physical institute in Graz, and during the same year was awarded with the Ignaz Lieben Prize for his work on the propagation of seismic waves. In a mine-shaft at Pribram he was able to differentiate between long-distance earthquakes and local microseismic activity with the use of seismometers

Hans Benndorf Also, he was the first scientist to solve the problem involving refraction of seismic rays in spherical layers. The term "Benndorfscher Satz" (Benndorf's relationship) is used to describe the constancy of the ray parameter across the spherical layers. A device known as a "Benndorf electrometer" is used for atmospheric electrical measurements.

Barton (crater) Barton crater is a 54-km (32-mi) diameter crater on Venus. It is the size at which craters on Venus begin to possess peak-rings instead of a single central peak. The floor of Barton crater is flat and radar-dark, indicating possible infilling by lava flows sometime following the impact. Barton's central peak-ring is discontinuous and appears to have been disrupted or separated during or following the cratering process. The crater is named after Clara Barton, the founder of the American Red Cross.

Nuclear Nebraska Nuclear Nebraska: The Remarkable Story of the Little County That Couldn’t Be Bought is a 2007 book by Susan Cragin which follows the controversy about a proposed low level nuclear waste dump, which was planned for Boyd County, Nebraska. In 1989, two multinational corporations and several government agencies proposed a waste dump and offered payment of $3 million per year for 40 years. The residents of the Boyd County farming community resisted the offer and controversy followed for almost two decades. During this time, the community was transformed "from a small group of isolated farmers to a defiant band of environmentalists". The opposition of the community eventually succeeded, and the license to build the dump was denied. Several governors became embroiled in the controversy, as well as legislators, bureaucrats and the community. One central figure went to jail and others were dismissed from their jobs. For many years, there was extensive coverage of the event by the news media. U.S. Senator Ben Nelson wrote the foreword to the book.

Arp 87 (also known as NGC 3808) is a pair of two interacting galaxies, NGC 3808A and NGC 3808B. They are situated in the Leo constellation. NGC 3808A, the brighter, is a peculiar spiral galaxy, while NGC 3808B is an irregular galaxy. The two galaxies were discovered on 10 April 1785 by William Herschel. The two are located about 330 million light-years (100 megaparsecs) away from the Earth. was observed by the Hubble Telescope in 2007, which revealed massive clouds of gas and dust flowing from one galaxy to another. Additionally, both galaxies appear to have been distorted.

Johnsen–Rahbek effect The occurs when an electric potential is applied across the boundary between a metallic surface and the surface of a semiconducting material. Under these conditions an attractive force appears, whose magnitude depends on the voltage and the specific materials involved. The effect is named after Danish engineers F. A. Johnsen and K. Rahbek, the first to investigate the effect at length.

Copper sweetening is a petroleum refining process using a slurry of clay and cupric chloride to oxidize mercaptans. The resulting disulfides are less odorous and usually very viscous, and are usually removed from the lower-boiling fractions and left in the heavy fuel oil fraction. introduces trace amount of copper into the resulting products, which tends to have detrimental effects as it leads to formation of gummy residues. Other sources of copper include contact with refinery parts made of copper and copper alloys. Copper is one of the most active instability promoters, and concentrations as low as 0.1 ppm can have marked negative effect. To combat these, metal deactivators are added to some fuels.

Peterson Field Guides The (PFG) are a popular and influential series of American field guides intended to assist the layman in identification of birds, plants, insects and other natural phenomena. The series was created and edited by renowned ornithologist Roger Tory Peterson (1908–1996). His inaugural volume was the classic 1934 book "A Field Guide to the Birds", published (as were all subsequent volumes) by the Houghton Mifflin Company. The PFG series utilized what became known as the Peterson Identification System, a practical method for field identification which highlights readily noticed visual features rather than focusing on the technical features of interest to scientists. The series both reflected and contributed to awareness of the emerging environmental movement. Most books in this series use a section of plates of drawings (usually reduced from commissioned paintings) rather than photographs of the subject species, grouped at the center of the book. This allows for idealized portraits that highlight the identifying "field marks" of each species; such field marks are often indicated by arrows or straight lines in the plate illustrations. However, in several books in this series, the plates consist of photographs (usually without such arrows or indicators), such as in the guides for the atmosphere, coral reefs, rocks and minerals, and the (old Charles Covell 1984 guide to) Eastern moths. In many books in this series (especially older editions), a number of the plates are in black and white
https://en.wikipedia.org/wiki?curid=14738913
Peterson Field Guides For examples, older editions of the Eastern reptiles/amphibians book had many black and white plates which were colorized for the current edition, and the original 1934 Eastern bird book had only 4 color plates. At least one book (insects) was entirely in black and white. However, most newer editions are often full-color (or almost full-color) and tend to be larger. One source claims that the increased size of one of the new editions (Eastern reptiles/amphibians) was considered detrimental to its use as a field guide by its own author and was a publisher decision. In some cases, new "editions" in this series are entirely new books with completely new texts and illustrations. For example, the fourth edition of the mammals guide has an entirely new text and illustrations by new author Fiona Reid, because the author (William Burt) and illustrator (Richard Grossenheider) of previous editions are both deceased. In fact, Grossenheider died prior to the publication of the "previous" third edition of 1976. Also, the current Northeastern moths guide by David Beadle and Seabrooke Leckie is an entirely new book than the out-of-print 1984 Eastern moths guide by Charles Covell. The Beadle/Leckie book covers a smaller geographical area and (one author claims) covers moths in greater detail. The old Covell book has been out-of-print for many years, but is currently available through the Virginia Museum of Natural History (which purchased the rights to that book)
https://en.wikipedia.org/wiki?curid=14738913
Peterson Field Guides The above situation of an old "edition" persisting alongside its intended replacement edition is not unique to the Eastern moths guide. George Petrides' 1988 Eastern trees book (PFG11B) was originally intended to replace Petrides' own 1958 Eastern tree and shrubs (PFG11A) book. However, both books remain popular and the original publisher still offers both books for sale (unlike the case of the old Eastern moths book). Differences between editions can serve to indicate changes in scientific perspective as well as changes species distribution. For example, the second edition of the freshwater fishes guide by Page and Burr (2011), published 20 years after the first edition, increased the number of species included from 768 to 909, largely due to the addition of previously unrecognized species (114), as well as increased numbers of newly established exotic species (16). It also expanded coverage of marine fish commonly found in freshwater (19). Both of these guides appeared in the Easton Press leather bound copies of the series. For that series the title of the Bond book was changed to ""Birds of the Caribbean"". "Birds of the West Indies" (1999), by James Bond Other volumes: Appweavers, Inc., the licensee of the Peterson field guides for mobile devices, has developed the Peterson Birds of North America and Peterson Feeder Birds of North America apps for mobile Apple products. The Peterson Birds of North America app also includes some content from other books in the Peterson field guide series.

William David Lindsay Ride AM (8 May 19266 November 2011), usually credited as W. D. L. Ride, was an Australian vertebrate zoologist and paleontologist who was the chair of the committee that authored updated editions of the International Code of Zoological Nomenclature. Ride was born in London, England in 1926, the eldest son of Sir Lindsay Tasman Ride. In 1957 he was appointed Director of the Western Australian Museum, in Perth, as well as a Reader in Zoology at the University of Western Australia. In 1975 he was appointed Director of the Australian Biological Resources Study, located within the Commonwealth Scientific and Industrial Research Organisation (CSIRO), in Canberra. Ride worked for the CSIRO 1974-1980. He also served as the head of the School of Applied Science, Canberra College of Advanced Education, 1982–87, and was appointed Principal of the College in 1987. Following retirement in 1987 he became a Visiting Fellow at the Australian National University until 2002. In 1984 Ride was made a Member of the Order of Australia. He died in 2011 in Canberra, aged 85. David Ride produced a field guide to Australia's mammals in 1970, a subject that had not been addressed since the publication of the second edition of "Furred Animals of Australia" in 1944. Although Ride's guide only provided brief diagnostic accounts of mammalian fauna, the work was the only generally available book until the Australian Museum issued the standard text of Australian mammalogy for their series National Photographic Index of Australian Wildlife

Cirrus intortus cloud Cirrus intortus is a variety of cirrus cloud. The name "cirrus intortus" is derived from Latin, meaning "twisted, wound". The variety of intortus clouds is specific to cirrus clouds, and they appear as interwound strands of cirrus clouds with a purely random pattern. The filaments are often curved in a very irregular pattern. Like other cirrus clouds, cirrus intortus occur at high altitudes.

Misoscale meteorology Misoscale is an unofficial scale of meteorological phenomena that ranges in size from 40 meters to about 4 kilometers. This scale was proposed by Ted Fujita, the father of the Fujita scale, to classify phenomenon of the order of the rotation within a thunderstorm, the scale of the funnel cloud of a tornado, and the size of the swath of destruction of a microburst. It is a subdivision of the microscale.

Superstatistics is a branch of statistical mechanics or statistical physics devoted to the study of non-linear and non-equilibrium systems. It is characterized by using the superposition of multiple differing statistical models to achieve the desired non-linearity. In terms of ordinary statistical ideas, this is equivalent to compounding the distributions of random variables and it may be considered a simple case of a doubly stochastic model. Consider an extended thermodynamical system which is locally in equilibrium and has a Boltzmann distribution, that is the probability of finding the system in a state with energy formula_1 is proportional to formula_2. Here formula_3 is the local inverse temperature. A non-equilibrium thermodynamical system is modeled by considering macroscopic fluctuations of the local inverse temperature. These fluctuations happen on time scales which are much larger than the microscopic relaxation times to the Boltzmann distribution. If the fluctuations of formula_3 are characterized by a distribution formula_5, the "superstatistical Boltzmann factor" of the system is given by This defines the superstatistical partition function for system that can assume discrete energy states formula_8. The probability of finding the system in state formula_9 is then given by Modeling the fluctuations of formula_3 leads to a description in terms of statistics of Boltzmann statistics, or "superstatistics"
https://en.wikipedia.org/wiki?curid=14793522
Superstatistics For example, if formula_3 follows a Gamma distribution, the resulting superstatistics corresponds to Tsallis statistics. can also lead to other statistics such as power-law distributions or stretched exponentials. One needs to note here that the word super here is short for superposition of the statistics.

Framboid The term framboid describes a micromorphological feature common to certain sedimentary minerals, particularly pyrite (FeS). The first known use of the term is ascribed to Rust in 1935 and is derived from the French ‘la framboise’, meaning ‘raspberry’, reflecting the appearance of the structure under magnification. Framboidal structure comprises roughly spherical aggregates of discrete equi-regular euhedral microcrystallites of around 0.5 μm in diameter, with the average aggregate size ranging from 5-20 μm. diameter tends to correlate positively with microcrystal size, and microcrystal packing is most commonly irregular and disordered. Framboids were once thought to be a fossilised bacterial colonies or microorganisms, but successful synthesis of this structure under laboratory conditions and observation of framboids in locations hostile to microbial life have discounted this theory. Framboidal pyrite is commonly found in coastal sediments, for instance marsh soils, marine and estuarine sediments, and beach sands. It can also be observed in coal as well as magmatic and carbonate rocks. Other minerals known to exhibit framboidal structures include magnetite, hematite, and greigite. Greigite is considered an essential precursor of framboidal pyrite formation.

POX 186 (also known as PGC 46982), located in the constellation Virgo, is a dwarf galaxy that is still forming. The galaxy is considered very small and distorted compared to most older galaxies, such as our own Milky Way Galaxy. It is currently believed to have first begun forming when two enormous clouds of gas and stars crashed into each other less than 100 million years ago, sparking new stars to form. Some people believe this may be direct evidence of a new theory, speculating that later-forming galaxies in our universe are smaller than galaxies that have been around for billions of years. appears near the star Spica, the brightest star in Virgo.

Wilhelm Hauchecorne Heinrich Lambert (13 August 1828 – 15 January 1900) was a German geologist of French Huguenot parentage who was born in Aachen. He studied at the University of Berlin and at the "Bergakademie" in Freiberg. Among his instructors were Heinrich Ernst von Beyrich (1815-1896), Gustav Rose (1798-1873) and Christian Samuel Weiss (1780-1856). Afterwards he became director of a copper mine near Rheinbreitbach, and in 1866 was appointed director of the Berlin Mining Academy. In 1873 he became the co-director of the Prussian National Geological Survey. Hauchecorne is credited with development of the Geological Survey's geological and mineralogical collections, and was responsible for consolidation of rock and mineral collections. He also introduced a standardization of color-codes for use on German geological maps that was eventually adopted throughout Europe. In 1892, the mineral hauchecornite was named in his honor.

Stellar-wind bubble A stellar-wind bubble is a cavity light years across filled with hot gas blown into the interstellar medium by the high-velocity (several thousand km/s) stellar wind from a single massive star of type O or B. Weaker stellar winds also blow bubble structures, which are also called astrospheres. The heliosphere blown by the solar wind, within which all the major planets of the Solar System are embedded, is a small example of a stellar-wind bubble. Stellar-wind bubbles have a two-shock structure. The freely-expanding stellar wind hits an inner termination shock, where its kinetic energy is thermalized, producing 10 K, X-ray-emitting plasma. The hot, high-pressure, shocked wind expands, driving a shock into the surrounding interstellar gas. If the surrounding gas is dense enough (number densities formula_1 or so), the swept-up gas radiatively cools far faster than the hot interior, forming a thin, relatively dense shell around the hot, shocked wind.

Maritime Continent is the name given primarily by meteorologists and oceanographers to the region of Southeast Asia which comprises, amongst other countries, Indonesia, Philippines and Papua New Guinea. Located between the Indian and Pacific Oceans, it is situated within a warm ocean region known as the Tropical Warm Pool. The maritime continent consists of many islands, peninsulas and shallow seas. The region is significant in meteorology because it is considered the most important energy source region in the entire global circulation system owing to a number of coincident factors, the most significant being geographic location and topography, both of which contribute to the development of the Tropical Warm Pool, which is the warmest large area of ocean on Earth. Coined by Colin Ramage in 1968, the name combines the terms "maritime" and "continent" normally used as opposites in the description of climate. Maritime air is humid, and continental air is dry. In the Southeast Asia region, land masses and bodies of water are, roughly-speaking, evenly distributed. Moreover, the land masses are characterized by high mountains, and the seas are among the warmest on the earth. This produces a widespread area of diurnal thunderstorms which pump huge quantities of moisture and heat high up into the atmosphere. These in turn feed the upper level winds which circle the globe.

Nunatak hypothesis In biogeography, particularly phytogeography, the nunatak hypothesis about the origin of a biota in formerly glaciated areas is the idea that some or many species have survived the inhospitable period on icefree land such as nunataks. Its antithesis is the "tabula rasa hypothesis", which posits that all species have immigrated into completely denuded land after the retreat of glaciers. By the mid-20th Century, the nunatak hypothesis was widely accepted among biologists working on the floras of Greenland and Scandinavia. However, while modern geology has established the presence of icefree areas during the last glacial maximum in both Greenland and Scandinavia, molecular techniques have revealed limited between-region genetic differentiation in many Arctic taxa, strongly suggesting a general capacity for long-distance dispersal among polar organisms. This does not directly disprove glacial survival. But it makes it less necessary as an explanation. Moreover, populations that survived on icefree land have probably in most cases been genetically flooded by postglacial immigrants.

Wernerian Natural History Society The (12 January 1808 – 16 April 1858), commonly abbreviated as the Wernerian Society, was a learned society interested in the broad field of natural history, and saw papers presented on various topics such as mineralogy, plants, insects, and scholarly expeditions. The Society was an offshoot of the Royal Society of Edinburgh, and from its beginnings it was a rather elite organization. The Society was named after Abraham Gottlob Werner, a German geologist who was a creator of Neptunism, a theory of superposition based on a receding primordial ocean that had deposited all the rocks in the crust. At this time all rocks, including basalt, and crystalline substances were thought by some to be precipitated from solution. Robert Jameson, Regius Professor of Natural History at the University of Edinburgh, was the founder and life president of the Society. In 1800, he spent a year at the mining academy in Freiberg, Saxony, where he studied under Werner. The Society was founded on 12 January 1808, and the first meeting of the Society occurred on 2 March 1808. Between 1811 and 1839 eight volumes of "Memoirs of the Wernerian Natural History Society" appeared. More than twelve of Jameson's papers on geology and mineralogy were published in these volumes, and he also contributed some on zoology and botany. Proceedings after 1839 were published in Jameson's "Edinburgh New Philosophical Journal". The Society hosted many of the notable scientists of its day

Wernerian Natural History Society There were no meetings from 1850–1856, which coincided with the decline of Jameson himself. It was eventually decided to close the Society down and dispose of its assets, and it finally closed on 16 April 1858. Members of the Wernerian Society were entitled to use the abbreviation M.W.S. after their name. "Corresponding members", based outside Edinburgh, used the designation C.M.W.S.

Ice II is a rhombohedral crystalline form of ice with a highly ordered structure. It is formed from ice I by compressing it at a temperature of 198 K at 300 MPa or by decompressing ice V. When heated it undergoes transformation to ice III. Ordinary water ice is known as ice I, (in the Bridgman nomenclature). Different types of ice, from ice II to ice XVIII, have been created in the laboratory at different temperatures and pressures. It is thought that the cores of icy moons like Jupiter's Ganymede may be made of ice II. The properties of ice II were first described and recorded by Gustav Heinrich Johann Apollon Tammann in 1900 during his experiments with ice under high pressure and low temperatures. Having produced ice III, Tammann then tried condensing the ice at a temperature between under of pressure. Tammann noted that in this state ice II was denser than he had observed ice III to be. He also found that both types of ice can be kept at normal atmospheric pressure in a stable condition so long as the temperature is kept at that of liquid air, which slows the change in conformation back to ice I. In later experiments by Bridgman in 1912, it was shown that the difference in volume between ice II and ice III was in the range of . This difference hadn't been discovered by Tammann due to the small change and was why he had been unable to determine an equilibrium curve between the two

Ice II The curve showed that the structural change from ice III to ice II was more likely to happen if the medium had previously been in the structural conformation of ice II. However, if a sample of ice III that had never been in the ice II state was obtained, it could be supercooled even below −70 °C without it changing into ice II. Conversely, however, any superheating of ice II was not possible in regards to retaining the same form. Bridgman found that the equilibrium curve between ice II and ice IV was much the same as with ice III, having the same stability properties and small volume change. The curve between ice II and ice V was extremely different, however, with the curve's bubble being essentially a straight line and the volume difference being almost always .

Ice V Ice V, pronounced "ice five", is a monoclinic crystalline phase of water, formed by cooling water to 253 K at 500 MPa. It has a density of 1.24 g cm (at 350 MPa). has a complicated structure, including 4-membered, 5-membered, 6-membered, and 8-membered rings and a total of 28 molecules in the unit cell. Ganymede's interior probably includes a liquid water ocean with tens to hundreds of kilometers of at its base.

Ice VI is a form of ice that exists at high pressure at the order of about 1 GPa (= 10 000 bar) and temperatures ranging from 130 up to 355 Kelvin (−143°C up to 82°C); see also the phase diagram of water. Its discovery and the discovery of other high pressure forms of water was published by P.W. Bridgman in January 1912. has a density of 1.31 g/cm³ and a tetragonal crystal system with the space group P4/nmc; its unit cell contains 10 water molecules and has the dimensions a=6.27 Å and c=5.79 Å. The triple point of "ice VI" with ice VII and liquid water is at about 82°C and 2.22 GPa and its triple point with ice V and liquid water is at 0.16°C and 0.6324 GPa = 6324 bar.

Ice VIII is a tetragonal crystalline form of ice formed from ice VII by cooling it below 5 °C. It is more ordered than ice VII, since the hydrogen atoms assume fixed positions. Ordinary water ice is known as ice I, (in the Bridgman nomenclature). Different types of ice, from ice II to ice XVIII, have been created in the laboratory at different temperatures and pressures.

Ice XV is a crystalline form of ice, the proton-ordered form of ice VI. It is created by cooling water to around 130 K at 1 GPa (9820 atm). Ordinary water ice is known as ice I, (in the Bridgman nomenclature). Different types of ice, from ice II to ice XVI, have been created in the laboratory at different temperatures and pressures. On 14 June, 2009, Christoph Salzmann at the University of Oxford and colleagues reported having created ice XV and say that its properties differ significantly from those predicted. In particular, ice XV is antiferroelectric rather than ferroelectric as had been predicted.

Lomonosov (Martian crater) Lomonosov is a crater on Mars, with a diameter close to 150 km. It is located in the Martian northern plains. Since it is large and found close (64.9° north) to the boundary between the Mare Acidalium quadrangle and the Mare Boreum quadrangle, it is found on both maps. The topography is smooth and young in this area, hence Lomonosov is easy to spot on large maps of Mars. The crater was named in 1973 in honour of Mikhail V. Lomonosov. The impact that created the crater has been identified as a possible source of tsunami waves which washed the shores of an ancient ocean formerly present in the basin Vastitas Borealis. In July 2019, further support was reported for an ancient ocean on Mars that may have been formed by a possible mega-tsunami source resulting from a meteorite impact creating Lomonosov crater.

Photo-Carnot engine A photo-Carnot engine is a Carnot cycle engine in which the working medium is a photon inside a cavity with perfectly reflecting walls. Radiation is the working fluid, and the piston is driven by radiation pressure. A quantum Carnot engine is one in which the atoms in the heat bath are given a small bit of quantum coherence. The phase of the atomic coherence provides a new control parameter. The deep physics behind the second law of thermodynamics is not violated; nevertheless, the quantum Carnot engine has certain features that are not possible in a classical engine. The internal energy of the photo-Carnot engine is proportional to the volume (unlike the ideal-gas equivalent) as well as the 4th power of the temperature (see Stefan–Boltzmann law) using formula_1 : The radiation pressure is only proportional to this 4th power of temperature but no other variables, meaning that for this photo-Carnot engine an isotherm is equivalent to an isobar: Using the first law of thermodynamics (formula_4) we can determine the work done through an adiabatic (formula_5) expansion by using the chain rule (formula_6) and setting it equal to formula_7 Combining these formula_8 gives us formula_9 which we can solve to find formula_10 Since the photo-Carnot engine needs a quantum coherence in the gas which is lost during the process, the rebuild of coherency takes more energy than is produced with the machine

Malcolm Bruce Smith (29 February 1924 – 27 July 2000) was an Australian chemist who studied the egg protein ovalbumin. He described the formation of S-ovalbumin from the native form (R-ovalbumin) as the pH of eggs rises over time. He was raised and educated at schools in Angaston and Nuriootpa in the Barossa Valley of South Australia, before winning a Country Scholarship to study Industrial Chemistry at the South Australian School of Mines in Adelaide. His studies were interrupted by World War II, when he was recruited to a laboratory position by the Munitions Department. After some years working for a public analyst in Adelaide, C.A.Smythe & Co, he was engaged by the Australian Council for Scientific and Industrial Research (later renamed the C.S.I.R.O) as a Technical Officer at the Division of Food Preservation and Transport in Sydney. He remained in this employment until retiring on 29 February 1984 from the position of Principal Research Scientist at the then named Division of Food Research. He was co-author of a history of his Division, published in 1979. He was awarded degrees of BSc and MSc at the University of New South Wales in 1956 and 1959, and was awarded the degree of Doctor of Science by that University in 1980, upon a discourse which discussed his published research into 'Physico-Chemical Studies on Proteins, with Particular Reference to the Structure and Stability of Egg Proteins.'
