In the amazing range of Yakov Borisovich Zeldovich’s research interests — from general problems of chemical physics, kinetics, combustion, detonation, and shock waves to elementary particles and cosmology — the physics of matter under extreme conditions occupies a special position. This paper reviews some of Ya.B.’s work on shock waves and equations of state of matter. Among Ya.B.’s basic ideas are the use of shock data to develop thermodynamically complete equations of state; shock compression of porous matter; and the adiabatic expansion of shock-compressed materials. The widespread use and development of these ideas as tools for extreme conditions studies are illustrated with examples.
