Columbia University – Dismantling the Nuclear Doomsday Machine: Scientists, the Bomb, and the Challenges of Nuclear Disarmament

Abstract  Eighty years ago, physicists first worked out what it would take to build a simple nuclear weapon and the immediate effects of its use. Five years later, theory and experiment became devastating facts as the United States built, tested, and then used the first nuclear weapons to destroy cities. Today, there are nine nuclear …
