Collection of philosophy, physics and speculative notes.
A free introductory textbook on relativity, written to be surprising, entertaining and thought-provoking on every page. It covers special and general relativity and cosmology, including black holes, wobbling space, and the speed limit of nature.
Pressure and Temperature in different metals including radioactive materials behind converging shock waves, is simulated using generalized form of equation of state. Tait’s equation of state of metals, is valid for pressures of the range of few mega bars and takes into account only elastic pressures. At such high pressures, metal undergo phase change and normal equation of state no more is valid. At such pressures, temperature in metals becomes very high and thermal and excitation pressures dominate over elastic pressure. It is observed that as shock approaches the center of sphere, excitation pressure dominates elastic as well as thermal pressure.
