Pyotr Kapitsa (1894-1984). Portrait of the Russian physicist and Nobel laureate Pyotr Leonidovich Kapitsa. Kapitsa worked in England until 1934 when, on a visit back to the USSR, he was detained and his passport taken away. He was forced instead to work in the USSR with state funding. In 1946, after refusing to work on the Soviet hydrogen bomb project, he was exiled to the countryside. After Stalin's death in 1953, he resumed his career. He shared the 1978 Nobel Prize for Physics for his work on low-temperature physics. The Kapitza resistance is named after him. Photographed in Moscow, Russia.
