Andrei Kolmogorov, Soviet mathematician

Andrei Kolmogorov (1903-1987), Soviet mathematician. Kolmogorov is widely considered one of the most prominent mathematicians of the 20th century. He made major advances in different scientific fields, including probability theory, topology (a type of geometry), turbulence, and classical mechanics. There are several theories, equations and laws in these fields named after Kolmogorov; from the Kolmogorov axioms in probability theory to the Kolmogorov space in topology. In 1931, two years after finishing his PhD at Moscow State University, he became a professor there. Later, he was head of the departments of probability, mathematical logic and statistics at the university. He also became dean of the Faculty of Mechanics and Mathematics.
