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) * Pie ...

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 the 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 na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 fo ...

Annales De Chimie Et De Physique
__NOTOC__ ''Annales de chimie et de physique'' (, ) 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: Science des matériaux'' in 1978; from 1998 to 20 ...

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 me ...

Description De L'Egypte (1809)
Description is any type of communication that aims to make vivid a place, object, person, group, or other physical entity. It is one of four rhetorical modes (also known as ''modes of discourse''), along with exposition, argumentation, and narration. Fiction writing Fiction writing specifically has modes such as action, exposition, description, dialogue, summary, and transition. Author Peter Selgin refers to ''methods'', including action, dialogue, thoughts, summary, scenes, and description. Description is the mode for transmitting a mental image of the particulars of a story. Together with dialogue, narration, exposition, and summarization, it is one of the most widely recognized of the fiction-writing modes. As stated in ''Writing from A to Z'', edited by Kirk Polking, it is more than the amassing of details; it is bringing something to life by carefully choosing and arranging words and phrases to produce the desired effect.

Lazare Carnot
Lazare Nicolas Marguerite, Comte Carnot (; 13 May 1753 – 2 August 1823) was a French mathematician, physicist, military officer, politician and a leading member of the Committee of Public Safety during the French Revolution. His military reforms, which included the introduction of mass conscription (''levée en masse''), were instrumental in transforming the French Revolutionary Army into an effective fighting force. Carnot was elected to the National Convention in 1792, and a year later he became a member of the Committee of Public Safety, where he directed the French war effort as one of the Ministers of War during the War of the First Coalition. He oversaw the reorganization of the army, imposed discipline, and significantly expanded the French force through the imposition of mass conscription. Credited with France's renewed military success from 1793 to 1794, Carnot came to be known as the "Organizer of Victory". Increasingly disillusioned with the radical politics of the ...

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

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. 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 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 consists of ranged weapons that launch Ammunition, 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 were 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 armour. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannon, and in contemporary usage, usually refers to Shell (projectile), shell-firing Field gun, guns, howitzers, and Mortar (weapon), mortars (collectively called ''barrel artillery'', ''cannon artil ...
