Nuclear Weapons is a history of nuclear weapons. From their initial theoretical development at the start of the twentieth century to the recent tests in North Korea, the author seeks to, at each point in the narrative, describe the basic science of nuclear weaponry. At the same time, he offers accounts and anecdotes of the personalities involved, many of whom he has known firsthand. Dr. Bernstein writes in response to what he sees as a widespread misunderstanding throughout the media of the basic workings and potential impact of nuclear weaponry.
