Jacques Frédéric Français
Jacques Frédéric Français (20 June 1775 – 9 March 1833) was a French engineer and mathematician. Biography Born on 20 June 1775, Jacques Frédéric Français was the son of a grocer of Saverne. He attended the Royal College of Strasbourg and enrolled voluntarily in the Army of the Rhine in 1793. In September 1794 he was transferred to the military engineering corps. Admitted to the École Polytechnique in the autumn of 1797, he moved in the spring of 1798 to the École du Génie de Metz and graduated with the brevet of first lieutenant. It was at this time that he wrote about the integration of differential equations. In January 1801 he took part in the Egyptian Campaign of the French Army. On his return in 1801 he was assigned to the port of Toulon. Named captain of the sappers in December 1801, he became second in command of the headquarters of the corps of engineers in November 1802.

Geotechnical Engineers
Geotechnical engineering, also known as geotechnics, is the branch of civil engineering concerned with the engineering behavior of earth materials. It uses the principles of soil mechanics and rock mechanics to solve its engineering problems. It also relies on knowledge of geology, hydrology, geophysics, and other related sciences. Geotechnical engineering has applications in military engineering, mining engineering, petroleum engineering, coastal engineering, and offshore construction. The fields of geotechnical engineering and engineering geology have overlapping knowledge areas. However, while geotechnical engineering is a specialty of civil engineering, engineering geology is a specialty of geology. History Humans have historically used soil as a material for flood control, irrigation purposes, burial sites, building foundations, and construction materials for buildings.

François Français
Joseph François Français was a French mathematician. François Français worked extensively on differential calculus. He developed on the previous work of Jean-Robert Argand on complex numbers. Biography François Français was a student in a seminary and afterwards he became a teacher at Colmar College in 1791 for one year and then moved to Strasbourg College in 1792. The aftermath of the French Revolution of 1789 interrupted his career. Not everyone supported the government that formed after the revolution. The revolution overthrew the monarchy of King Louis XVI to establish a republic but brought in years of turmoil that finally led to the rise of Napoleon. France faced both internal and external wars. A civil war broke out in 1793 in the coastal region of Vendée in western France as a reaction against the imposition of conscription. This became known as the Guerre de Vendée or War in the Vendée. The next month royalists and peasants came together in February 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Annales De Gergonne
The (, ), commonly known as the (, ''Annals of Gergonne''), was a mathematical journal published in Nîmes, France from 1810 to 1831 by Joseph Diez Gergonne. The annals were largely devoted to geometry, with additional articles on history, philosophy, and mathematics education showing interdisciplinarity. "In the , Gergonne established in form and content a set of exceptionally high standards for mathematical journalism. New symbols and new terms to enrich mathematical literature are found here for the first time. The journal, which met with instant approval, became a model for many another editor. Cauchy, Poncelet, Brianchon, Steiner, Plücker, Crelle, Poisson, Ampere, Chasles, and Liouville sent articles for publication." Operational calculus was developed in the journal in 1814 by Francois-Joseph Servois. Francois-Joseph Servois (1814Analise Transcendante.

Louis François Antoine Arbogast
Louis François Antoine Arbogast (4 October 1759 – 8 April 1803) was a French mathematician. He was born at Mutzig in Alsace and died at Strasbourg, where he was professor. He wrote on Series (mathematics), series and the Calculus, derivatives known by his name: he was the first writer to separate the symbols of operation from those of quantity, introducing systematically the operator notation ''DF'' for the derivative of the function ''F''. In 1800, he published a calculus treatise where the first known statement of what is currently known as Faà di Bruno's formula appears, 55 years before the first published paper of Francesco Faà di Bruno on that topic. Biography He was professor of mathematics at the Collège de Colmar and entered a mathematical competition run by the St Petersburg Academy. His entry was to bring him fame and an important place in the history of the development of the calculus. Arbogast submitted an essay to the St Petersburg Academy in which he came ...

Complex Numbers
In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted , called the imaginary unit and satisfying the equation i^= -1; every complex number can be expressed in the form a + bi, where and are real numbers. Because no real number satisfies the above equation, was called an imaginary number by René Descartes. For the complex number is called the , and is called the . The set of complex numbers is denoted by either of the symbols \mathbb C or . Despite the historical nomenclature, "imaginary" complex numbers have a mathematical existence as firm as that of the real numbers, and they are fundamental tools in the scientific description of the natural world. Complex numbers allow solutions to all polynomial equations, even those that have no solutions in real numbers. More precisely, the fundamental theorem of algebra asserts that every non-constant polynomial equation with real or complex coefficients has ...

Étienne-Louis Malus
Étienne-Louis Malus (; ; 23 July 1775 – 23 February 1812) was a French officer, engineer, physicist, and mathematician. Malus was born in Paris, France and studied at the military engineering school at Mezires where he was taught by Gaspard Monge. He participated in Napoleon's expedition into Egypt (1798 to 1801). He was also a member of the mathematics section of the Institut d'Égypte. Malus became a member of the Académie des Sciences in 1810. In 1810 the Royal Society of London awarded him the Rumford Medal. His mathematical work was almost entirely concerned with the study of light. He studied geometric systems called ''ray systems'', closely connected to Julius Plücker's '' line geometry''. He conducted experiments to verify Christiaan Huygens's theories of light and rewrote the theory in analytical form. His discovery of the polarization of light by reflection was published in 1809 and his theory of double refraction of light in crystals, in 1810. Malus at ...

Cartesian Coordinates
In geometry, a Cartesian coordinate system (, ) in a plane is a coordinate system that specifies each point uniquely by a pair of real numbers called ''coordinates'', which are the signed distances to the point from two fixed perpendicular oriented lines, called '' coordinate lines'', ''coordinate axes'' or just ''axes'' (plural of ''axis'') of the system. The point where the axes meet is called the '' origin'' and has as coordinates. The axes directions represent an orthogonal basis. The combination of origin and basis forms a coordinate frame called the Cartesian frame. Similarly, the position of any point in three-dimensional space can be specified by three ''Cartesian coordinates'', which are the signed distances from the point to three mutually perpendicular planes. More generally, Cartesian coordinates specify the point in an -dimensional Euclidean space for any dimension . These coordinates are the signed distances from the point to mutually perpendicular fixed h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Trafalgar
The Battle of Trafalgar was a naval engagement that took place on 21 October 1805 between the Royal Navy and a combined fleet of the French Navy, French and Spanish Navy, Spanish navies during the War of the Third Coalition. As part of Napoleon's planned invasion of the United Kingdom, the French and Spanish fleets combined to take control of the English Channel and provide the Grande Armée safe passage. The allied fleet, under the command of French admiral Pierre-Charles Villeneuve, sailed from the port of Cádiz in the south of Spain on 18 October 1805. They encountered a British fleet under Horatio Nelson, 1st Viscount Nelson, Lord Nelson, recently assembled to meet this threat, in the Atlantic Ocean along the southwest coast of Spain, off Cape Trafalgar. Nelson was outnumbered, with 27 British ships of the line to 33 Franco-Spanish ships, including the largest warship in either fleet, the Spanish ''Spanish ship Nuestra Señora de la SantÃsima Trinidad, ...
