A quarter of a century after the first man-made nuclear explosion was detonated near Alamogordo, New Mexico, eighteen world-renowned scientists presented an authoritative first-hand overview of the events and developments that have shaped the atomic age. The articles contained in this volume were written for a special twenty-fifth-anniversary issue of the Bulletin of the Atomic Scientists, a pioneering journal founded by scientists from the Chicago Manhattan Project laboratories in 1945. The purpose was then and still is to bring to the public a full understanding of the reality of nuclear energy and of its implications for mankind in the future. Alamogordo Plus Twenty-Five Years is an examination of what the experts have to say about the challenges that nuclear energy contribute to: disarmament of nuclear weapons, the effects of fall-out pollution, the future uses of nuclear energy, etc., and also of how it is being used to met these challenges for the benefit of mankind.
