The night of physicists: Operation Epilson: Heisenberg, Hahn, Weizsacker and the German bomb

In the spring of 1945 the Allies arrested the physicists who were believed to have worked on the German nuclear program. Interned in an English country house owned by MI6, their conversations were secretly recorded. "Operation Epsilon" sought to determine how close Nazi Germany had come to building an atomic bomb. It was in captivity that the interned physicists first heard of the attack on Hiroshima. That night was also one of great shock and personal defeat for the physicists—they assumed they alone had discovered nuclear fission. This is the story of Nazi Germany's hunt for an atomic bomb, and a tale of the genius, hubris, and guilt of lauded, respected scientists.
