" Before 1939, it was the accepted belief of scientists that it was theoretically possible to release atomic energy. But nobody knew any practical method of doing it. By 1942, however, we knew that the Germans were working feverishly to find a way to add atomic energy to all the other engines of war with which they hoped to enslave the world. But they failed. We may be grateful to Providence that the Germans got the V-1’s and V-2’s late and in limited quantities and even more grateful that they did not get the atomic bomb at all. "
