Russian physicist and university teacher (1890?1952)
Yuri Alexandrovich Krutkov
(
Russian
:
Юрий Александрович Крутков
, 29 May 1890 ? 12 September 1952) was a Russian and among the first Soviet theoretical physicists. Krutkov worked on cosmology, quantum theory, statistical mechanics, tensor fields, and other areas. He was a professor of physics at the
University of St. Petersburg
from 1921-1952.
Life and work
[

]
Krutkov was born in
St. Petersburg
where his father Alexander taught Greek, Latin and Russian. The family moved to
Lubny
for sometime. Krutkov graduated from the
St. Petersburg gymnasium
in 1908 and went to study physics at the University where he studied under
Paul Ehrenfest
. He was among the first physicists who were purely theoretical. When Ehrenfest moved to Leiden University, he too did the same.
His first work was on
adiabatic invariants
. Funded by a
Rockefeller Foundation
grant, he worked in Germany and Holland in 1922-23 during which time he met
Albert Einstein
. Here he pointed out an error in Einstein's critique of
Friedmann
's work on the expanding universe.

Krutkov later considered rotational Brownian motion and looked at the theory of rolling motion of ships floating on a randomly moving sea and examined the physical predictions. He applied statistical mechanics to
gyroscopes
and wrote a book on the general theory of gyroscopes in collaboration with
Alexei Krylov
.

Krutkov taught at the Leningrad Polytechnic Institute and at the Leningrad University where his students included
V. A. Fock
. During World War II he was imprisoned but continued to work on some aerodynamics problems with
A.N. Tupolev
.
