Sigmund Leifson was Head, Department of Physics at the University of Nevada. From the Preface this book is based on facts drawn from thoroughly reliable sources. The portion dealing with the details of the atomic bomb project follows closely the report prepared for the War Department by Professor H. D. Smyth of Princeton, and some of the preliminary background material is digested from certain fundamental articles in Science and Time. Bassoni's "Energy and Matter: and Darrow's "Renaissance fo Physics" have also been helpful sources of general information. Many details related to the bomb project, which are contained in Professor Smyth's report, have been either subordinated or omitted, in an effort to give the reader the essential facts in a logically coordinated manner. If information that is interesting and pertinent is not given, it is because response to security requirements that it be withheld from the report released to the public. The authors have endeavored to state carefully and clearly the facts relating to the manufacture of U-235 and plutonium. The subject is so intrinsically fascinating. Leifson was one of the earliest researchers in spectroscopy of the vacuum ultraviolet. Among the sections presented are: The Atomic Theory, Thermite, Explosive Compounds, Kinetic Energy, Nuclear Forces, At Gibson Island, Isotopes, Radioactivity, Atom-Smashing, The Cyclotron, Uranium, Fission, Pure U-235, U-235 vs. Plutonium, Gaseous Diffusion, Centrifugal Separation, Electromagnetic Separation, The First Chain-Reacting Pile, Shielding and Control, The Hanford Plant, Los Alamos, Atomic Bomb Explosion, Military Future of Atomic Energy, and Peacetime Future of Atomic Energy.
