Zhevakin is credited for identifying ionized helium as the valve for the heat engine that drives the pulsation of Cepheid variable stars.[1][2][3][4]

Early life and education

S. A. Zhevakin was born on April 11, 1916 in Moscow. The family moved to Nizhny Novgorod in the late 1920s. Graduated from N. I. Lobachevsky State University of Nizhny Novgorod in 1939, and, after two years of working at various local factories, entered graduate program in 1941. However, because of the invasion of Nazi Germany, was conscripted into army in July 1941, where served with distinction until January 1946. Wounded twice.

After returning to graduate school, defended thesis in 1949.

gollark: It would be limited to 100ms of CPU per event or something, but you could have people trigger events and such too much.
gollark: Actually, hmm, people could maliciously invoke it a lot, but I suppose they would have to give it money so I'm not sure that's an awful issue.
gollark: So the "contract" would basically be a sandboxed bit of code which can be triggered on events, which is publicly viewable/auditable, and which can send and be sent krist.
gollark: Maybe I should try and clarify the exact model of this a bit, hm.
gollark: Say, 1KST per thousand invocations (precise number up for debate).
