David Bohm's life involved a series of contradictions. Refused security clearance for work on the atom bomb during World War II, he made critical contributions to the development of the bomb. In the early 1940s, Bohm performed theoretical calculations of collisions of deuterons and protons for his Ph.D. under Robert Oppenheimer at the University of California, Berkeley.
