George Harvey (FRS)
George Harvey, Esq., (died 29 October 1834) was an English mathematician, known for his scientific and engineering writings, on meteorology, ship building, and colour blindness. Life Harvey was based in Plymouth, where he trained as a physician before specialising in mathematics. He tutored William Yolland in mathematics. Later he became a lecturer in mathematics at the Royal Military Academy, Woolwich. Around 1826 his name was mentioned in correspondence about a professorial post at the University of Virginia, between Francis Walker Gilmer and Peter Barlow (mathematician), Peter Barlow. The chair went in the end to Charles Bonnycastle. Harvey became a Fellow of the Royal Society of Edinburgh in 1824 his proposer being Thomas Frederick Colby. Next year he became Fellow of the Royal Society of London. He was also a Fellow of the Royal Astronomical Society, Geological Society and Linnaean Society. During his last years, Harvey was Local Secretary at Plymouth for the Society for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, structure, space, models, and change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman mathematician recorded by history was Hypati ...

Linnaean Society
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Encyclopædia Metropolitana
''The Encyclopædia Metropolitana'' was an encyclopedic work published in London, from 1817 to 1845, by part publication. In all it came to quarto, 30 vols., having been issued in 59 parts (22,426 pages, 565 plates). Origins Initially the project was part of transitional arrangements in 1817 under which Samuel Taylor Coleridge moved publisher, from John Mathew Gutch to Rest Fenner, working with the Rev. Thomas Curtis. Coleridge was offered the role of editor; he wrote the Introduction, which appeared in January 1818, brought out to compete with the fifth edition of the ''Encyclopædia Britannica'' which had appeared in 1817 in 20 volumes. Fenner, however, dropped the publication after five part-volumes. The ''Encyclopædia Metropolitana'' was revived in 1820 by the intervention of Bishop William Howley, concerned also to compete with the ''Britannica'', in this case to counter its secular tendency. Howley brought in William Rowe Lyall to take charge. Lyall in turn appointed Edw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snow Flakes Harvey Meteorology
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is cold ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
