Georg Wilhelm Richmann
Georg Wilhelm Richmann () (22 July 1711 – 6 August 1753), (Julian calendar, Old Style: 11 July 1711 – 26 July 1753) was a Russian Empire, Russian Imperial physicist of Baltic Germans, Baltic German descent. Richmann did pioneering work on electricity, atmospheric electricity, and calorimetry. He died by electrocution in Saint Petersburg, St. Petersburg when struck by apparent ball lightning produced by an experiment attempting to ground the electrical discharge from a storm. Early life and education Georg Wilhelm Richmann was born on 22 July 1711 (Julian calendar, Old Style, 11 July 1711) in the city of Pernau, Pernov (today Pärnu, Estonia) in Swedish Livonia, which in 1721 became part of the Russian Empire as a result of the Great Northern War. Of Baltic Germans, Baltic German descent, Richmann's father died of pandemic, plague before he was born, and his mother remarried. In his early years he studied in Reval (today's Tallinn, Estonia); later he studied in Germany at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calorimetry
In chemistry and thermodynamics, calorimetry () is the science or act of measuring changes in ''state variables'' of a body for the purpose of deriving the heat transfer associated with changes of its state due, for example, to chemical reactions, physical changes, or phase transitions under specified constraints. Calorimetry is performed with a calorimeter. Scottish physician and scientist Joseph Black, who was the first to recognize the distinction between heat and temperature, is said to be the founder of the science of calorimetry. Indirect calorimetry calculates heat that living organisms produce by measuring either their production of carbon dioxide and nitrogen waste (frequently ammonia in aquatic organisms, or urea in terrestrial ones), or from their consumption of oxygen. Lavoisier noted in 1780 that heat production can be predicted from oxygen consumption this way, using multiple regression. The dynamic energy budget theory explains why this procedure is correct.

1753 Deaths
Events January–March * January 3 – King Binnya Dala of the Hanthawaddy Kingdom orders the burning of Ava, the former capital of the Kingdom of Burma. * January 29 – After a month's absence, Elizabeth Canning returns to her mother's home in London and claims that she was abducted; the following criminal trial causes an uproar. * February 17 – The concept of electrical telegraphy is first published in the form of a letter to ''Scots' Magazine'' from a writer who identifies himself only as "C.M.". Titled "An Expeditious Method of Conveying Intelligence", C.M. suggests that static electricity (generated by 1753 from "frictional machines") could send electric signals across wires to a receiver. Rather than the dot and dash system later used by Samuel F.B. Morse, C.M. proposes that "a set of wires equal in number to the letters of the alphabet, be extended horizontally between two given places" and that on the receiving side, "Let a ball be suspende ...

Mort Du Richmann
''Mort'' is a fantasy novel by British writer Terry Pratchett. Published in 1987, it is the fourth '' Discworld'' novel and the first to focus on the character Death, who only appeared as a side character in the previous novels. The title is the name of its main character, and is also a play on words: in French and Catalan, ''mort'' means "death". The French language edition is titled ''Mortimer'', and the Catalan language edition is titled ''Morth''. In the BBC's 2003 Big Read contest, viewers voted on the "Nation's Best-loved Book"; ''Mort'' was among the Top 100 and chosen as the most popular of Pratchett's novels. In 2004, Pratchett stated that ''Mort'' was the first Discworld novel with which he was "pleased", stating that in previous books, the plot had existed to support the jokes, but that in ''Mort'', the plot was integral.Terry Pratchet ...

American Institute Of Physics
The American Institute of Physics (AIP) promotes science and the profession of physics, publishes physics journals, and produces publications for scientific and engineering societies. The AIP is made up of various member societies. Its corporate headquarters are at the American Center for Physics in College Park, Maryland, but the institute also has offices in Melville, New York, and Beijing.

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

French Language
French ( or ) is a Romance language of the Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French ( Francien) largely supplanted. French was also influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the ( Germanic) Frankish language of the post-Roman Frankish invaders. Today, owing to France's past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in 29 countries across multiple continents, most of which are members of the ''Organisation internationale de la Francophonie'' ...
