Society Of Arcueil
The Society of Arcueil was a circle of French scientists who met regularly on summer weekends between 1806 and 1822 at the country houses of Claude Louis Berthollet and Pierre Simon Laplace at Arcueil, then a village 3 miles south of Paris. Members In 1807, when the first collection of ''"Mémoires de Physique et de Chimie de la Société d'Arcueil"'' was published, a list of contributing members read: * Claude Louis Berthollet (1748-1822) * Pierre Simon Laplace (1749-1827) * Friedrich Heinrich Alexander von Humboldt (1769-1859) * Louis Jacques Thenard (1777-1857) * Joseph Louis Gay-Lussac (1778-1850) * Jean Baptiste Biot (1774-1862) * Augustin Pyramus de Candolle (1778-1841) * Hippolyte-Victor Collet-Descotils (1773-1815) * Amedée Barthélemy Berthollet (1780-1810) In the course of the following years they were joined by: * Étienne-Louis Malus (1775-1812) * Dominique François Jean Arago (1786-1853) * Jacques Etienne Bérard (1789-1869) * Jean Antoine Chaptal (1756-1832) * ...

Claude Louis Berthollet
Claude Louis Berthollet (, 9 December 1748 – 6 November 1822) was a Savoyard-French chemist who became vice president of the French Senate in 1804. He is known for his scientific contributions to theory of chemical equilibria via the mechanism of reverse chemical reactions, and for his contribution to modern chemical nomenclature. On a practical basis, Berthollet was the first to demonstrate the bleaching action of chlorine gas, and was first to develop a solution of sodium hypochlorite as a modern bleaching agent. Biography Claude Louis Berthollet was born in Talloires, near Annecy, then part of the Duchy of Savoy, in 1749. He started his studies at Chambéry and then in Turin where he graduated in medicine. Berthollet's great new developments in works regarding chemistry made him, in a short period of time, an active participant of the Academy of Science in 1780. Berthollet, along with Antoine Lavoisier and others, devised a chemical nomenclature, or a system of name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Traité Élémentaire De Chimie
''Traité élémentaire de chimie'' (''Elementary Treatise on Chemistry'') is a textbook written by Antoine Lavoisier published in 1789 and translated into English by Robert Kerr in 1790 under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries''. It is considered to be the first modern chemical textbook. The book defines an element as a single substance that can't be broken down by chemical analysis and from which all chemical compounds are formed, publishing his discovery that fermentation produces carbon dioxide (carbonic gas) and spirit of wine, saying that it is "more appropriately called by the Arabic word alcohol since it is formed from cider or fermented sugar as well as wine", and publishing the first chemical equation "grape must = carbonic acid + alcohol", calling this reaction "one of the most extraordinary in chemistry", noting "In these experiments, we have to assume that there is a true balance or equation between the ...

Jules Paul Benjamin Delessert
Jules Paul Benjamin Delessert (14 February 1773 – 1 March 1847) was a French banker and naturalist. He was an honorary member of the Académie des Sciences and many species were named from his natural history collections. Biography He was born at Lyon, the son of Étienne Delessert (1735–1816), the founder of the first fire insurance company and the first discount bank in France. Their ancestors had moved from Switzerland after 1685. Young Delessert was travelling in England when the French Revolution broke out, but he hastened back to join the Paris National Guard in 1790, becoming an officer of artillery in 1793. His father bought him out of the army, however, in 1795 in order to entrust him with the management of his bank. Gifted with remarkable energy, he started many commercial enterprises, founding the first cotton factory at Passy in 1801, and a sugar factory in 1802 where Jean-Baptiste Quéruel developed the industrial manufacture of sugar from sugar beet, and for ...

Annales De Chimie Et De Physique
__NOTOC__ ''Annales de chimie et de physique'' ( French for ''Annals of Chemistry and Physics'') is a scientific journal founded in Paris, France, in 1789 under the title ''Annales de chimie''. One of the early editors was the French chemist Antoine Lavoisier. Lavoisier, an aristocrat, was guillotined in May 1794, ostensibly for tax fraud: and the journal was not published from 1794 to 1796 while the Reign of Terror was at its height under the French Directory. In 1815, it became the ''Annales de chimie et de physique'', and was published under that name for the next 100 years. In 1914, it split into two successor journals. The first one, '' Annales de physique'', was latterly published by EDP Sciences under the same name up to 2009, when it became integrated in the ''European Physical Journal'' series as the '' European Physical Journal H – Historical Perspectives on Contemporary Physics''. The second successor, ''Annales de chimie'', later became '' Annales de chimie: Scien ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Achard
Franz Karl Achard (28 April 1753 – 20 April 1821) was a German (Prussian) chemist, geoscientist, physicist, and biologist. His principal discovery was the production of sugar from sugar beets. Life and work Achard was born in Berlin, the son of preacher Max Guillaume Achard, a descendant of Huguenot refugees, and his wife Marguerite Elisabeth (Rouppert). He studied physics and chemistry in Berlin. He became interested in sugar refining through his stepfather. At the age of 20, Achard entered the "Circle of Friends of Natural Sciences" and met Andreas Sigismund Marggraf, then director of the physical classes at the Royal Academy of Sciences. Achard studied many subjects, including meteorology, evaporation chillness, electricity, telegraphy, gravity, lightning arresters, and published in German and French. Achard was a favourite of King Frederick II of Prussia, and directly reported to the King on his research twice a week. About a study on the influence of electricity on ...

Description De L'Egypte (1809)
Description is the pattern of narrative development that aims to make vivid a place, object, character, or group. Description is one of four rhetorical modes (also known as ''modes of discourse''), along with exposition, argumentation, and narration. In practice it would be difficult to write literature that drew on just one of the four basic modes. As a fiction-writing mode Fiction-writing also has modes: action, exposition, description, dialogue, summary, and transition. Author Peter Selgin refers to ''methods'', including action, dialogue, thoughts, summary, scenes, and description. Currently, there is no consensus within the writing community regarding the number and composition of fiction-writing modes and their uses. Description is the fiction-writing mode for transmitting a mental image of the particulars of a story. Together with dialogue, narration, exposition, and summarization, description is one of the most widely recognized of the fiction-writing modes. As stated ...

Lazare Carnot
Lazare Nicolas Marguerite, Count Carnot (; 13 May 1753 – 2 August 1823) was a French mathematician, physicist and politician. He was known as the "Organizer of Victory" in the French Revolutionary Wars and Napoleonic Wars. Education and early life Carnot was born on 13 May 1753 in the village of Nolay, in Burgundy, as the son of a local judge and royal notary, Claude Carnot and his wife, Marguerite Pothier. He was the second oldest of seven children. At the age of fourteen, Lazare and his brother were enrolled at the ''Collège d'Autun'', where he focused on the study of philosophy and the classics. He held a strong belief in stoic philosophy and was deeply influenced by Roman civilization. When he turned fifteen, he left school in Autun to strengthen his philosophical knowledge and study under the Society of the Priests of Saint Sulpice. During his short time with them, he studied logic, mathematics and theology under the Abbe Bison. After being impressed with Lazare's work a ...

Institut De France
The (; ) is a French learned society, grouping five , including the Académie Française. It was established in 1795 at the direction of the National Convention. Located on the Quai de Conti in the 6th arrondissement of Paris, the institute manages approximately 1,000 foundations, as well as museums and châteaux open for visit. It also awards prizes and subsidies, which amounted to a total of over €27 million per year in 2017. Most of these prizes are awarded by the institute on the recommendation of the . History The building was originally constructed as the Collège des Quatre-Nations by Cardinal Mazarin, as a school for students from new provinces attached to France under Louis XIV. The inscription over the façade reads "JUL. MAZARIN S.R.E. CARD BASILICAM ET GYMNAS F.C.A M.D.C.LXI", attesting that Mazarin ordered its construction in 1661.

French Directory
The Directory (also called Directorate, ) was the governing five-member committee in the French First Republic from 2 November 1795 until 9 November 1799, when it was overthrown by Napoleon, Napoleon Bonaparte in the Coup of 18 Brumaire and replaced by the French Consulate, Consulate. ''Directoire'' is the name of the final four years of the French Revolution. Mainstream historiography also uses the term in reference to the period from the dissolution of the National Convention on 26 October 1795 (4 Brumaire) to Napoleon's coup d’état. The Directory was continually at war with foreign coalitions, including Kingdom of Great Britain, Britain, Habsburg monarchy, Austria, Kingdom of Prussia, Prussia, the Kingdom of Naples, Russian Empire, Russia and the Ottoman Empire. It annexed Austrian Netherlands, Belgium and the left bank of the Rhine, while Bonaparte conquered a large part of Italy.

Mathematics
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of ...

Gaspard Monge
Gaspard Monge, Comte de Péluse (9 May 1746 – 28 July 1818) was a French mathematician, commonly presented as the inventor of descriptive geometry, (the mathematical basis of) technical drawing, and the father of differential geometry. During the French Revolution he served as the Minister of the Marine, and was involved in the reform of the French educational system, helping to found the École Polytechnique. Biography Early life Monge was born at Beaune, Côte-d'Or, the son of a merchant. He was educated at the college of the Oratorians at Beaune. In 1762 he went to the Collège de la Trinité at Lyon, where, one year after he had begun studying, he was made a teacher of physics at the age of just seventeen. After finishing his education in 1764 he returned to Beaune, where he made a large-scale plan of the town, inventing the methods of observation and constructing the necessary instruments; the plan was presented to the town, and is still preserved in their library. ...

Artillery
Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'', ''gun artillery'', or - a layman t ...
