▪ 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.
