Nobel laureate Prof. Roy J. Glauber is the last alive scientist from the Theory Division of the Manhattan Project at Los Alamos. His clear, fluent and articulate narration brings first hand information on the life at Los Alamos, the main scientific characters there, the Trinity test of the first ever nuclear weapon, the bombing of Japan and the political aftermath of the project. Glauber's account is documented with audiovisual material recently declassified from the Los Alamos Archive.
