Pyotr Leonidovitch Kapitsa
Pyotr Leonidovitch Kapitsa (Russian: ПётрЛеонидовичКапица), (July 9th 1894 - April 8th 1984) is a Russian physicist , Nobel Prize of physics in 1978.
Kapitsa is born with Kronstadt, it studies with the polytechnic Université of Saint-Pétersbourg. He works in England with the Laboratoire Cavendish of 1923 with 1934 where he collaborates with Ernest Rutherford. In 1929 it is elected member of the Royal Society of which it directs the Mond laboratory of 1930 at 1934 dates to which it turns over in Soviet Union for a conference. Its passport is seized during its stay and it cannot turn over to England. It is named with the head of the institute of physics of the Academy of Science of Russia in 1935.
In 1946 its refusal to work on the atomic Arme Russian is worth to him to be dislocated of its functions, posts that it begins again only in 1955, two after the death of Stalin. With its death in 1984 Kapitsa is the only member of the Academy of Science of Russia which is not member of the Communist party.
Kapitsa receives the Nobel Prize of physics in 1978 “for its fundamental inventions and discoveries in the field of physics at low temperature”.
The resistance of Kapitsa is the strength of the heat flow between the Hélium liquid and a solid producing a discontinuity of temperature to the level of the interface.
