Frank, Ilya M. (1908-1990), a Russian theoretical physicist, shared the 1958 Nobel Prize for physics with P. A. Cherenkov and I. Y. Tamm. Frank, a professor at Moscow University, and Tamm explained the effects of a discovery that Cherenkov made in 1934. Cherenkov showed that a transparent substance gives off light when electrons or other charged particles move through it faster than light.
