@High Seas,
HS, I worked with thermonuclear weapons in the US Air Force in the late fifties, but didn't know the mathematical equations for it. We saw lot'sa training films with explosions, but none in any of the testing done during that period.
BTW, I met the scientist who designed the aerodynamics on nuclear weapons that I worked with on a Mexico cruise several years ago, Robert Brodsky. We still keep in touch.
