Part of the Masters of Modern Physics series, this book by Nobel laureate Hans Bethe, assembles some of his most powerful essays written after World War II. A strong advocate for nuclear disarmament, Bethe focuses his writings on the hydrogen bomb, weapons research, arms control, and nuclear power. Other themes include his contributions to astrophysics, and his reflections on friends and associates, including Oppenheimer, Feynman, Dyson, Hoerlin, and Ewald.
