Leonty Magnitsky
Leonty Filippovich Magnitsky (), born Telyatin (; June 9, 1669, in Ostashkov – October 19, 1739, in Moscow) was a Russian mathematician and educator.. Biography Magnitsky was born into a peasant family. According to some accounts, he graduated from the Slavic Greek Latin Academy in Moscow. From 1701 and until his death, he taught arithmetic, geometry and trigonometry at the Moscow School of Mathematics and Navigation, becoming its director in 1716. In 1703, Magnitsky wrote his famous ''Arithmetic (book), Arithmetic'' (Арифметика; 2,400 copies), which was used as the principal textbook on mathematics in Russia until the middle of the 18th century. Mikhail Lomonosov was himself taught by this book, which he called the "gates to his own erudition".. In 1703, Magnitsky also produced a Russian edition of Adriaan Vlacq's log tables called ''Таблицы логарифмов и синусов, тангенсов и секансов'' (Tables of logarithms, sines, tangents ...

Scabies
Scabies (; also sometimes known as the seven-year itch) is a contagious human skin infestation by the tiny (0.2–0.45 mm) mite ''Sarcoptes scabiei'', variety ''hominis''. The word is from . The most common symptoms are severe itchiness and a papular, pimple-like rash. Occasionally, tiny burrows may appear on the skin. In a first-ever infection, the infected person usually develops symptoms within two to six weeks. During a second infection, symptoms may begin within 24 hours. These symptoms can be present across most of the body or just in certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children. The itch is often worse at night. Scratching may cause skin breakdown and an additional bacterial infection in the skin. Various names have been given to this condition and the name 'seven year itch' has been recorded in many documents from the 1800's. Although the 1952 The_Seven_Year_Itch_( ...

Richard Mead
Richard Mead, FRSFRCP (11 August 1673 – 16 February 1754) was an English physician. His work, ''A Short Discourse concerning Pestilential Contagion, and the Method to be used to prevent it'' (1720), was of historic importance in advancing the understanding of transmissible diseases. Life Richard was born in Stepney, London on 11 August 1673, son of Matthew Mead (1630–1699), who was an Independent minister. He was the eleventh of thirteen children. He studied at Utrecht for three years under JG Graevius. Having decided to follow the medical profession, he then went to Leiden and attended the lectures of Paul Hermann and Archibald Pitcairne. In 1695 he graduated in philosophy and physic at Padua, and in 1696 he returned to London, entering at once on a successful practice. His ''Mechanical Account of Poisons'' appeared in 1702, and, in 1703, he was admitted to the Royal Society, to whose ''Transactions'' he contributed in that year a paper on the parasitic nature of s ...

1727 In Science
The year 1727 in science and technology involved some significant events. Astronomy * Maharaja Jai Singh II begins construction of the Jantar Mantar observatory at Jaipur. Biology * Rev. Stephen Hales publishes ''Vegetable Staticks'', containing an account of key experiments in plant physiology; and makes the first measurement of blood pressure. Forssmann, Werner. Nobel Lecture in Physiology or Medicine, 1956. Mathematics * This year's French Academy of Sciences prize is based on a problem on the masting of ships: to calculate the number of masts to use and where in the ship to locate them. Pierre Bouguer gains the award for his paper ''On the masting of ships''; and two other prizes, one for his dissertation ''On the best method of observing the altitude of stars at sea'' and the other for his paper ''On the best method of observing the variation of the compass at sea''.

Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by Charles II of England, King Charles II and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the society's president, according to a set of statutes and standing orders. The members of Council and the president are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow ...

Isaac Newton
Sir Isaac Newton () was an English polymath active as a mathematician, physicist, astronomer, alchemist, theologian, and author. Newton was a key figure in the Scientific Revolution and the Age of Enlightenment, Enlightenment that followed. His book (''Mathematical Principles of Natural Philosophy''), first published in 1687, achieved the Unification of theories in physics#Unification of gravity and astronomy, first great unification in physics and established classical mechanics. Newton also made seminal contributions to optics, and Leibniz–Newton calculus controversy, shares credit with German mathematician Gottfried Wilhelm Leibniz for formulating calculus, infinitesimal calculus, though he developed calculus years before Leibniz. Newton contributed to and refined the scientific method, and his work is considered the most influential in bringing forth modern science. In the , Newton formulated the Newton's laws of motion, laws of motion and Newton's law of universal g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Winstanley
Henry Winstanley (31 March 1644 – 27 November 1703) was an English painter, engineer, and merchant who constructed the first Eddystone Lighthouse after losing two of his ships on the Eddystone rocks. He died while working on the project during the Great Storm of 1703. Early life and career He was born in Saffron Walden, Essex, and baptised there on 31 March 1644. His father, Henry, became land steward to the Earl of Suffolk, owner of Audley End House, in 1652, and young Henry also worked at Audley End, first as a porter and then as a secretary. In 1666, Audley End House was bought by Charles II for use as a base when attending Newmarket races, and it became effectively a royal palace.

Eddystone Lighthouse
The Eddystone Lighthouse is a lighthouse on the Eddystone Rocks, south of Rame Head in Cornwall, England. The rocks are submerged below the surface of the sea and are composed of Precambrian gneiss. View at 1:50000 scale The current structure is the fourth to be built on the site. The first lighthouse (Winstanley's) was swept away in a powerful storm, killing its architect and five other men in the process. The second (Rudyard's) stood for fifty years before it burned down. The third (Smeaton's) is renowned because of its influence on Lighthouse, lighthouse design and its importance in the development of concrete for building; its upper portions were re-erected in Plymouth as a monument. The first lighthouse, completed in 1699, was the world's first open ocean lighthouse, although the Cordouan Lighthouse off the western French coast preceded it as the first offshore lighthouse.

Extratropical Cyclone
Extratropical cyclones, sometimes called mid-latitude cyclones or wave cyclones, are low-pressure areas which, along with the anticyclones of high-pressure areas, drive the weather over much of the Earth. Extratropical cyclones are capable of producing anything from cloudiness and mild rain, showers to severe hail, thunderstorms, blizzards, and tornadoes. These types of cyclones are defined as Synoptic scale meteorology, large scale (synoptic) Low-pressure area, low pressure weather systems that occur in the middle latitudes of the Earth. In contrast with tropical cyclones, extratropical cyclones produce rapid changes in temperature and dew point along broad lines, called weather fronts, about the center of the cyclone. Terminology The term "cyclone" applies to numerous types of low pressure areas, one of which is the extratropical cyclone. The descriptor ''extratropical'' signifies that this type of cyclone generally occurs outside the tropics and in the middle latitudes of Ea ...
