Alvin Weinberg is one of the most influential nuclear engineers & physicists in the [url] having participated in many high profile projects from the early days of nuclear research on into the 1980s. This book is his autobiography and it's peppered with first-hand accounts of major historical events. He writes about the events of December 2, 1942, when Fermi set into motion the first chain reaction in a uranium pile and goes on to describe what happened during the "First Nuclear Era" a period he admits that has now largely run its course. A proponent of nuclear power, Weinberg also exposed its down- side risks and for years remained in the forefront of strong science administration.
