This 1993 volume studies the technical research that led to the first atomic bombs. The authors explore how the 'critical assembly' of scientists, engineers, and military personnel at Los Alamos, collaborated during World War II to create a new approach to research. Readers will find this book a crucial resource for understanding the underpinnings of contemporary science and technology.

Unlike earlier histories of Los Alamos, this book treats in detail the research and development that led to the implosion and gun weapons; the research in nuclear physics, chemistry, and metallurgy that enabled clear bomb, the 'Super.'
