Otto Frisch took part in some of the most momentous developments in modern physics, notably the discovery of nuclear fission (a term which he coined). His work on the first atom bomb, which he saw explode in the desert 'like the light of a thousand suns', brought him into contact with figures such as Robert Oppenheimer, Edward Teller, Richard Feynman and the father of electronic computers, John von Neumann. He also encountered the physicists who had made the great discoveries of recent generations: Einstein, Rutherford and Niels Bohr. This characterful book of reminiscences sheds an engagingly personal light on the people and events behind some of the greatest scientific discoveries of this century, illustrated with a series of fascinating photographs and witty sketches by the author himself.
