###
Born: 1901 in St Petersburg, Russia

Died: 31 Dec 1944 in Moscow, USSR

**Kochin** graduated from Petrograd University (St Petersburg changed
its name to Petrograd in 1914 and then to Leningrad in 1924) in 1923. He
taught mathematics and mechanics there (called Leningrad University by
this time) from 1924 to 1934.
Kochin moved Moscow University in 1934 and worked there for the rest
of his life. In addition he was head of the mechanics section of the Mechanics
Institute of the Academy from 1939 to 1944.

Kochin's research was on meteorology, gas dynamics and shock waves in
compressible fluids. He gave the solution to the problem of small amplitude
waves on the surface of an uncompressed liquid in *Towards a Theory of
Cauchy-Poisson Waves* in 1935.

He also worked on the pitch and roll of ships. In aerodynamics he introduced
formulas for aerodynamic force and for the distribution of pressure.

He wrote textbooks on hydromechanics and vector analysis.
