Paul-Quentin Desains

Quentin Paul Desains ( born July 12, 1817 in Saint- Quentin, † May 3, 1885 in Paris) was a French physicist.

Career

Desains first went to school in Saint- Quentin and put his baccalaureate at the Lycée Louis -le- Grand in Paris from. After he won in 1835 the first prize in the nationwide entrance examinations ( concours général) in physics, he studied at the École Normale Supérieure of Paris ( ENS) and at the Sorbonne, among others, Pierre Louis Dulong and Claude Pouillet. In 1839 he received the degree in mathematics and physics, and was a high school teacher in Caen. Later, he was a teacher at the Collège Stanislas in Paris (1841-1847) and at the Lycée Saint -Louis (1841-1844), where his brother Édouard teacher. At the same time he taught from 1844 to 1853 at the Lycée Condorcet later (then Collège royal de Bourbon and Lycée Bonaparte impérial ). In 1848 he received his doctorate in Paris with a physical work on heat radiation and a work in chemistry. In 1853 he, succeeding Pouillet professor of physics at the Faculté des Sciences in Paris. In 1868 he was one of the founders of the Physics Laboratory of the École des hautes études pratiques and taught there as a Director. This laboratory for the training of physicists was a great success, among other things, taught there and Pierre Curie. At times, he was also an astronomer at the Paris Observatory.

Paul Desains dealt in particular with optics and thermodynamics, particularly the verification of the Dulong -Petit law, heat of fusion and heat radiation, and observations of terrestrial magnetism. He pointed out that the thermal radiation has similar characteristics to the light wave.

During the siege of Paris during the Franco-German War he made with Charles d' Almeida for maintaining telegraphic connections in the wider city area.
