This book, a completely new and different version from the old 'Serber Says' published forty years ago, is intended for graduate students in the field of nuclear physics. Written with a pedagogical aim it emphasizes topics of basic interest not only in nuclear physics, but also other branches of physics such as atomic physics, solid state physics and nuclear engineering.

More than seventy years ago, American forces exploded the first atomic bombs over the Japanese cities of Hiroshima and Nagasaki, causing great physical and human destruction. The young scientists at Los Alamos who developed the bombs, which were nicknamed Little Boy and Fat Man, were introduced to the basic principles and goals of the project in March 1943, at a crash course in new weapons technology. The lecturer was physicist Robert Serber, J. Robert Oppenheimer's protege, and the scientists learned that their job was to design and build the world's first atomic bombs. Notes on Serber's lectures were gathered into a mimeographed document titled TheLos Alamos Primer, which was supplied to all incoming scientific staff. The Primer remained classified for decades after the war. Published for the first time in 1992, the Primer offers contemporary readers a better understanding of the origins of nuclear weapons. Serber's preface vividly conveys the mingled excitement, uncertainty, and intensity felt by the Manhattan Project scientists. This edition includes an updated introduction by Pulitzer Prize-winning historian Richard Rhodes. A seminal publication on a turning point in human history, The Los Alamos Primer reveals just how much was known and how terrifyingly much was unknown midway through the Manhattan Project. No other seminar anywhere has had greater historical consequences.

This work is the memoir of one of the key scientists involved in the atomic bomb and the chief research assistant and intimate friend of J. Robert Oppenheimer. A prominent member of the Manhattan Project, Robert Serber was one of a team of scientists who assembled the bombs on Tinian Island for transport to Hiroshima and Nagasaki. He was also one of the first Americans to walk among the Japanese ruins after the catastrophe. Written with science historian Robert P. Crease, this self-portrait is the story of Serber's life before, during and after World War II. It brings into focus the leading figures and events during this period in American science. Serber tells of his wartime experiences at Tinian Island and in Japan, in letters to his wife Charlotte, herself a key player at Los Alamos and the only female group leader there. These letters depict what Serber saw, such as the rows of iron office safes protruding from the rubble of Hiroshima, and the grazing horse whose hair had been scorched on one side by the fireball but was untouched on the other. Serber is also eloquent about the troubles he faced as a result of his refusal to take part in public debate about the morality of his wartime work; how his opposition to rapidly developing the hydrogen bomb earned him the enmity of Edward Teller and others; and how he was investigated and his security clearance challenged, several years before Oppenheimer's. Serber also recounts stories involving Oppenheimer, Murray Gell-Mann, Ernest O. Lawrence and Edward Teller.
