▪ Russian mathematical physicist
born Dec. 22 [Dec. 10, Old Style], 1898, St. Petersburg, Russia
died Dec. 27, 1974, Leningrad, Russia, U.S.S.R. [now St. Petersburg, Russia]
Fock became progressively deaf at a young age because of injuries sustained during military service in
World War I. In 1922 he graduated from Petrograd University (
Saint Petersburg State University), and he taught there from 1924, becoming a professor in 1932. The Hartree-Fock equation, improved by him in 1930, became a basic approximation method for calculations involving multielectron atoms (
atom) in quantum chemistry. He also introduced the Fock representation (1928) for a quantum oscillator, particularly important in
quantum field theory; the Fock space with varying dimensions (1932) to legitimize the second quantization (many-body formalism); and the method of Fock functionals (1934) for treating systems with an indeterminate number of particles in
quantum electrodynamics. In 1926 Fock and several other physicists independently proposed a relativistic generalization of the Austrian physicist Erwin Schrödinger (
Schrödinger, Erwin)'s wave equation (
Schrödinger equation).
Fock was arrested on phony political charges in 1937, during the Great Purge (
purge trials), but he was quickly released thanks to the Russian physicist Pyotr Kapitsa (
Kapitsa, Pyotr Leonidovich), who appealed directly to Joseph Stalin (
Stalin, Joseph). In 1939 Fock solved the problem of the motion of ponderable bodies (objects with appreciable mass) in Albert Einstein (
Einstein, Albert)'s general relativity by using harmonic coordinates. In 1939 Fock was elected a full member of the U.S.S.R. Academy of Sciences (
Sciences, Academy of) (he had been a corresponding member since 1932). Fock also developed philosophical interpretations of
relativity and quantum mechanics that he considered consistent with
Marxism.
