History of science

The Making of the Atomic Bomb
by Richard Rhodes
Simon & Schuster, 1986.

Five years in the writing, Richard Rhodes' history of the atomic bomb has become a landmark in the field of science popularization. At over 900 pages long, it presents a comprehensive account of the events that led to the production of the terrible weapon ever devised by man. It is really several different books in one, shifting in tone and emphasis as it follows the concept from start to finish: from scientific discovery to military-industrial project to the study of political decision-making in war.

Scientific discovery

The first third of the book is largely an account of scientific discovery, as experimenters worked to uncover the structure of the atom at the turn of the 20th century. Even in this foundational period, it was easy to see that nuclear bombardment involved energies that were orders of magnitude greater than the chemical reactions already familiar to science. It was natural to speculate about how to unlock those energies someday, and thus the dream of nuclear energy developed right alongside the earliest experiments. Frederick Soddy described the possibility of nuclear energy in his book The Interpretation of Radium (1909), based on his work alongside Ernst Rutherford. H. G. Wells then picked up on the idea in his famous novel The World Set Free (1914).

But the early nuclear bombardments could only play with atomic forces at a small scale. With the discovery of nuclear fission, it became obvious that a chain reaction was possible and could be used to multiply the energies released. But it would not be worked out in a time of peace on earth and brotherhood among men. With the expulsion of Jewish academics from German universities and the looming onset of World War II, the leading lights of atomic science left Europe for America. In just a few years, the center of gravity in the physics world had shifted across the Atlantic.
