Jean Pierre Chardenon
Jean Pierre Chardenon (1714 – 16 March 1769) was a French physician and chemist. Chardenon theorized on the medical aspects of chemistry including an attempt to explain the composition and origin of organic oils which he explained as being made up of acid, water, phlogiston, and earth. Chardenon was born in Dijon to Guillaume and Marguerite Canquoin. He was baptized on 22 July 1714. Little is known of his education but his death certificate claimed that he studied medicine at Montpellier, but no such records exist. He became a surgeon in Paris but gave it up for a physician position in Dijon where he joined the one-year-old Academie des Sciences, Arts et Belles-Lettres de Dijon, serving as its secretary from 1752 for a decade. He connected ideas from physics with those in chemistry and from there to medicine. He interpreted the weight increase of metals upon calcination in 1762 as being due to the loss of phlogiston and used the analogy of a fishnet being buoyed up by corks. Once ...

Phlogiston Theory
The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others. Phlogiston theory led to experiments which ultimately concluded with the discovery of oxygen. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlogiston and that they ''dephlogisticate'' when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dijon
Dijon (, , ) (dated) * it, Digione * la, Diviō or * lmo, Digion is the prefecture of the Côte-d'Or department and of the Bourgogne-Franche-Comté region in northeastern France. the commune had a population of 156,920. The earliest archaeological finds within the city limits of Dijon date to the Neolithic period. Dijon later became a Roman settlement named ''Divio'', located on the road between Lyon and Paris. The province was home to the Dukes of Burgundy from the early 11th until the late 15th centuries, and Dijon became a place of tremendous wealth and power, one of the great European centres of art, learning, and science. The city has retained varied architectural styles from many of the main periods of the past millennium, including Capetian, Gothic, and Renaissance. Many still-inhabited town-houses in the city's central district date from the 18th century and earlier. Dijon's architecture is distinguished by, among other things, '' toits bourguignons'' (Burgu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Académie Des Sciences, Arts Et Belles-Lettres De Dijon
The Académie de Dijon was founded by Hector-Bernard Pouffier, the most senior member of the Parlement de Bourgogne, in 1725. It received royal ''lettres patentes'' in 1740. In 1775, it became the "Académie des Sciences, Arts et Belles-Lettres de Dijon." From 1855 to 1869, it was called the "Académie Impériale des Sciences, Arts et Belles-Lettres de Dijon" before returning in 1870 to the name "Académie des Sciences, Arts et Belles-Lettres de Dijon." In July 1750, it sponsored a prize competition on the question of "whether the reestablishment of the sciences and the arts contributed to purifying morals." Jean-Jacques Rousseau won the prize by arguing in the negative, in his Discourse on the Arts and Sciences. In 1754, he again competed for the prize with his Discourse on the Origin and Basis of Inequality Among Men, but did not win the prize that year. The Académie des Sciences, Arts et Belles-Lettres de Dijon still exists, and still offers the prize. Famous members * Charl ...

Louis-Bernard Guyton De Morveau
Louis-Bernard Guyton, Baron de Morveau (also Louis-Bernard Guyton-Morveau after the French Revolution; 4 January 1737 – 2 January 1816) was a French chemist, politician, and aeronaut. He is credited with producing the first systematic method of chemical nomenclature. Early career Guyton de Morveau was born in Dijon, where he served as a lawyer, then '' avocat général'', of the Dijon ''parlement''. In 1773, already interested in chemistry, he proposed use of "muriatic acid gas" for fumigation of buildings and as a result is sometimes given credit for having suggested chlorine in this use. However, chlorine was not well characterized at that time, and hydrogen chloride (made by reacting sodium chloride Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. With molar masses of 22.99 and 35.45 g ... and sulfuric acid) was ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Dijon
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of ...
