context_page_description: Vladimir Aleksandrovich Fock was a Soviet physicist, who did foundational work on quantum mechanics and quantum electrodynamics.
context_section_description: His primary scientific contribution lies in the development of quantum physics and the theory of gravitation, although he also contributed significantly to the fields of mechanics, theoretical optics, physics of continuous media. In 1926, he derived the Klein–Gordon equation. He gave his name to Fock space, the Fock representation and Fock state, and developed the Hartree–Fock method in 1930. He made many subsequent scientific contributions during the rest of his life. Fock developed the electromagnetic methods for geophysical exploration in a book The theory of the study of the rocks resistance by the carottage method (1933), the methods are called the well logging in modern literature.
  Fock made significant contributions to general relativity theory, specifically for the many-body problems. Fock criticised on scientific grounds both Einstein's general principle of relativity, as being devoid of physical substance, and the equivalence principle, as interpreted as the equivalence of gravitation and acceleration, as having only a local validity.
  In Leningrad, Fock created a scientific school in theoretical physics and raised the physics education in the USSR through his books. He wrote the first textbook on quantum mechanics Fundamentals of Quantum Mechanics (1931, 1978) and a very influential monograph The Theory of Space, Time and Gravitation (1955).
  Historians of science, such as Loren Graham, see Fock as a representative and proponent of Einstein's theory of relativity within the Soviet world. At a time when most Marxist philosophers objected to relativity theory, Fock emphasized a materialistic understanding of relativity that coincided philosophically with Marxism. 
  He was a full member (academician) of the USSR Academy of Sciences (1939) and a member of the International Academy of Quantum Molecular Science.
