"In 1992, David C. Cassidy's groundbreaking biography of Werner Heisenberg, Uncertainty, was published to resounding acclaim from scholars and critics. Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg's role in the Nazi atomic bomb project. In this book, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist's personal responsibility and guilt when serving an abhorrent military regime."--Global Books in Print.
