Hans Bethe won the 1967 Nobel Prize for Physics for determining the nuclear processes that power the sun and stars. Bethe was also involved in the creation of the atom and hydrogen bombs at the Los Alamos project during World War II. Bethe is now an activist for a nuclear freeze, and co-authored a New York Times op-ed on the topic. He joins the show to discuss the development and future of nuclear arms.
