A flawed but interesting book. Bernstein refers to the excellent Richard Rhodes books that cover much of the same ground and gives some reasons why he still thought it was worth writing this book, but I have to say that Rhodes' books are better. Having said that, Bernstein's quirky style has much to recommend it, and his descriptions of personal experiences are in places riveting. I particularly enjoyed the description of his visit to a nuclear weapons test site. Bernstein also covers some of the science in more detail than Rhodes, and the book is a much shorter read, so may be more appropriate for someone with limited time. Read... Enjoy.
