Corps Des Ponts Et Chaussées
The ''Corps des ponts, des eaux et des forêts'' (in English "Corps of Bridges, Waters and Forests") is a technical Grand Corps of the French State (grand corps de l'Etat). Its members are senior officials, mainly employed by the French Ministry of Environment and Energy and by the Ministry of Agriculture. Most of them are from École polytechnique, where they are selected based on their ranking, and from AgroParisTech where they are selected based on an entrance exam, others are from École normale supérieure (Ulm) or the regular curriculum of the École des ponts ParisTech. People entering the Corps (around 60 each year) are trained either at AgroParisTech, École des ponts ParisTech or abroad in specific fields, in particular when they are willing to pursue a PhD. In 2002, the ''Corps des ponts et chaussées'', and the different corps formed by the civil aviation engineers, the geography engineers and the meteorological engineers merged. In 2009, the ''Corps des ponts et chaus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The effort was sanctioned by the French National Assembly, which, after the French Revolution wanted to bring uniformity to the multiple measurements and standards used throughout the nation. In particular, his tables were intended for precise land surveys, as part of a greater cadastre effort. The tables were vast, calculating logarithms from 1 to 200,000, with values calculated to between fourteen and twenty-nine decimal places, (which de Prony recognized was excessively pre ...

Pierre Méchain
Pierre François André Méchain (; 16 August 1744 – 20 September 1804) was a French astronomer and surveyor who, with Charles Messier, was a major contributor to the early study of deep-sky objects and comets. Life Pierre Méchain was born in Laon, the son of the ceiling designer and plasterer Pierre François Méchain and Marie–Marguerite Roze. He displayed mental gifts in mathematics and physics but had to give up his studies for lack of money. However, his talents in astronomy were noticed by Jérôme Lalande, for whom he became a friend and proof-reader of the second edition of his book "L'Astronomie". Lalande then secured a position for him as assistant hydrographer with the Naval Depot of Maps and Charts at Versailles, where he worked through the 1770s engaged in hydrographic work and coastline surveying. It was during this time—approximately 1774—that he met Charles Messier, and apparently, they became friends. In the same year, he also produced his first astron ...

Étienne-Louis Malus (; ; 23 July 1775 – 23 February 1812) was a French officer, engineer, physicist, and mathematician. Malus was born in Paris, France. He participated in Napoleon's expedition into Egypt (1798 to 1801) and was 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 attempted to identify the relationship between the polarising angle of reflection that he had discovered, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
