Hans Bethe and David Mermin Discuss the Early History of Solid State Physics.
In February 25, 2003, Hans Bethe at age 96 discussed the early history of solid state physics with David Mermin, a colleague on the Physics Faculty of Cornell University.
Hans Bethe (1906-2005) was a German-American nuclear physicist and winner of the 1967 Nobel Prize in Physics.
After becoming an American citizen and gaining his security clearance, war work took him to the Radiation Laboratory at MIT, working on microwave radar. After spending the summer of 1942 at the University of California, Berkeley working on a design for the atomic bomb, Bethe was selected by J. Robert Oppenheimer to lead the T (Theoretical) Division of Los Alamos. He and his wife Rose moved to Los Alamos in 1943. Their son, Henry, was born at Los Alamos.
As theory chief, Bethe oversaw and coordinated the work of the various theory groups working on creating a model for how neutrons diffuse through a critical mass, figuring out how to calculate the efficiency of nuclear explosions, determining critical masses and the limits of sub-critical ones, understanding how liquids and gases behaved in fractions of micro-seconds at immense temperatures and pressures, and designing an initiator.
Bethe completed the theoretical work on the implosion method used in the Trinity test and “Fat Man” weapon dropped on Nagasaki, which validated his results. He also studied the hydrodynamic aspects of implosion, the neutron initiator, and radiation propagation from an exploding atomic bomb.
