Étienne Bobillier
Étienne Bobillier (17 April 1798 – 22 March 1840) was a French mathematician. He was born in Lons-le-Saunier, France. At the age of 19, he was accepted into the École Polytechnique and studied there for a year. However, due to a shortage of money, in 1818 he became an instructor in mathematics at the École des Arts et Métiers in Châlons-sur-Marne. In 1829, he was sent to Angers to be director of studies. The following year he served in the National Guard during the 1830 revolution. In 1832 he returned to Châlons after his post was abolished, and was promoted to professor. In 1836 he began suffering from health problems, but continued teaching; declining to take a leave to recuperate. As a result, he died in Châlons at the relatively early age of 41. He is noted for his work on geometry, particularly the algebraic treatment of geometric surfaces and the polar of curves. He also worked on statics and the catenary In physics and geometry, a catenary ( , ) is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lons-le-Saunier
Lons-le-Saunier () is a commune and capital of the Jura Department, eastern France. Geography The town is in the heart of the Revermont region, at the foot of the first plateau of the Jura massif. The Jura escarpment extends to the east and south, while to the west lies the plain of Bresse and to the north extensive vineyards. The river Vallière runs through the town, rising in a typical Jura blind valley not far away, at Revigny. It has been conduited since the 1960s on grounds of hygiene, since sewage outlets run into it. A small section remains in the open air near the parc des Bains, and only a single bridge (the pont de la Guiche) remains. The town is approximately equally placed between Besançon, Dijon, Bourg-en-Bresse and Geneva, though the last of these lies on the other side of the Jura massif. It is served by the A39 autoroute, by which Dijon can be reached in about an hour and Lyon in an hour and a half. The town's railway station lies on the line from S ...

Châlons-en-Champagne
Châlons-en-Champagne () is a city in the Grand Est region of France. It is the capital of the Departments of France, department of Marne (department), Marne, despite being only a quarter the size of the city of Reims. Formerly called Châlons-sur-Marne, the city was officially renamed in 1995. It should not be confused with the Burgundian town of Chalon-sur-Saône. History The city was a Gallic and later a Gallo-Roman settlement known in Latin as ''Catalaunum'', taking its name from the Catalauni, a Belgae, Belgic tribe dwelling in the region of modern Champagne (province), Champagne. Châlons is conjectured to be the site of several battles, including the Battle of Châlons (274), Battle of Châlons, fought in 274 between Roman Emperor Aurelian and Emperor Tetricus I of the Gallic Empire, and the 451 Battle of the Catalaunian Plains, which turned back the westward advance of Attila. The Hôtel de Ville, Châlons-en-Champagne, Hôtel de Ville was completed in 1776. Plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French People
French people () are a nation primarily located in Western Europe that share a common Culture of France, French culture, History of France, history, and French language, language, identified with the country of France. The French people, especially the native speakers of langues d'oïl from northern and central France, are primarily descended from Roman people, Romans (or Gallo-Romans, western European Celts, Celtic and Italic peoples), Gauls (including the Belgae), as well as Germanic peoples such as the Franks, the Visigoths, the Suebi and the Burgundians who settled in Gaul from east of the Rhine after the fall of the Roman Empire, as well as various later waves of lower-level irregular migration that have continued to the present day. The Norsemen also settled in Normandy in the 10th century and contributed significantly to the ancestry of the Normans. Furthermore, regional ethnic minorities also exist within France that have distinct lineages, languages and cultures such ...

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians was Thales of Miletus (); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales's theorem. The number of known mathematicians grew when Pythagoras of Samos () established the Pythagorean school, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathematics for its own sake begins. The first woman math ...

École Polytechnique
(, ; also known as Polytechnique or l'X ) is a ''grande école'' located in Palaiseau, France. It specializes in science and engineering and is a founding member of the Polytechnic Institute of Paris. The school was founded in 1794 by mathematician Gaspard Monge during the French Revolution and was militarized under Napoleon I in 1804. It is still supervised by the Ministry of Armed Forces (France), French Ministry of Armed Forces. Originally located in the Latin Quarter, Paris, Latin Quarter in central Paris, the institution moved to Palaiseau in 1976, in the Paris-Saclay, Paris-Saclay technology cluster. French engineering students undergo initial military training and have the status of paid Aspirant, officer cadets. The school has also been awarding doctorates since 1985, masters since 2005 and bachelors since 2017.

Catenary
In physics and geometry, a catenary ( , ) is the curve that an idealized hanging chain or wire rope, cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of Catenary arch, arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette,#MathWorld, MathWorld or, particularly in the materials sciences, an example of a funicular curve, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the Graph of a function, graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A ha ...
