An Outline of Atomic Physics,
by the Members of the Physics Staff of the University of Pittsburgh
What was atomic physics like in April 1946? All I know is that "the bomb" is not mentioned in the book's index. Probably because the bomb technology was still a secret at that point, maybe even from the Russians!
Other than a little underlining, the book is in good shape. This 414 page hardcover includes many diagrams and even some photographs :one of an electric generator with a cascade- type vacuum tube. That huge thing looks pretty weird to me. Buy this book! To be found in the physics section of our store, priced at $4.
