Equation of State: Manhattan Project Developments and Beyond.

The hydrodynamic response of materials under extreme conditions of pressure, temperature and strain is dependent on the equation of state of the matter in all its states of existence. The Trinity plutonium implosion device development required the Los Alamos physics and engineering research community to advance equation of state theory and experiment further and faster than ever before. The unpredicted high yield from the Trinity fission device explosion and the push to design the "Super" thermonuclear device initiated 75 years of unprecedented theoretical and experimental research and technological progress into equation of state development.
