An engaging and informative history. Kean specializes in books about quirky people. The nuclear physicists, and the teams that hunted the German physicists, were quirky and amusing.

The core message is that the US government was sure the Nazis would have the first bombs, unless the US raced ahead with a prodigeous effort, while hobbling the German effort with attacks and sabotage. The actual German outcome was Werner Heisenberg's Uranium Machines, cubes-on-strings-in-heavy-water. Heisenberg bragged to his Allied captors in May 1945 about his 670% increase in neutrons, cluelessly unaware of the huge Manhattan Project, its megawatt reactors, successors to Fermi's successful atomic pile experiments at the University of Chicago in December 1942.

By August 1945, the German scientists were incarcerated at the Farm Hall estate near London. The August 6 BBC announcment of the Hiroshima nuclear attack left them devastated.

• p408 As Goudsmit later commented, "That was the first time they really felt that Germany had lost the war. Up to that time, they had believed that Germany at least had won the war of the laboratory. No more."

  • Weizsacker then rallied his comrades towards face-saving confabulations. They failed because of lack of resources, and they hadn't wanted to build a bomb for moral reasons.

• p409 Heisenberg worked out a complete theory of the American bomb design over the next week. This demonstrates why the Allies considered him the most dangerous scientist in the world.
