Pyotr Leonidovich Kapitsa or Peter Kapitza FRS (Russian: Пётр Леонидович Капица, Romanian: Petre Capița; 9 July [O.S. 26 June] 1894 – 8 April 1984) was a leading Soviet physicist and Nobel laureate, whose research focused on low-temperature physics.
Pyotr Kapitsa discovered superfluidity in 1937 when he observed liquid helium flowing without friction – in other words with no loss of kinetic energy. He received the 1978 Nobel Prize in Physics for his work.
Apr 4, 2024 · Pyotr Leonidovich Kapitsa (born June 26 [July 8, New Style], 1894, Kronshtadt, Russian Empire—died April 8, 1984, Moscow, Russia, U.S.S.R.) was a Soviet physicist who invented new machines for the liquefaction of gases and in 1937 discovered the superfluidity of liquid helium.

In 1934, Kapitsa constructed a new device for producing liquid helium, which cooled the gas by periodic expansions. For the first time, a machine had been made which could produce liquid helium in large quantities without previous cooling with liquid hydrogen.
Late in the 1940’s Kapitsa turned his attention to a totally new range of physical problems. He invented high power microwave generators – planotron and nigotron (1950- 1955) and discovered a new kind of continuous high pressure plasma discharge with electron temperatures over a million K.
Pyotr Leonidovich Kapitsa (Russian Пётр Леонидович Капица) (July 9, 1894 – April 8, 1984) was a Russian physicist who discovered super-fluidity with contribution from John F. Allen and Don Misener in 1937.
