University of Chicago Graduate Problems in Physics covers a broad range of topics, from simple mechanics to nuclear physics. The problems presented are intriguing ones, unlike many examination questions, and physical concepts are emphasized in the solutions. Many distinguished members of the Department of Physics and the Enrico Fermi Institute at the University of Chicago have served on the candidacy examination committees and have, therefore, contributed to the preparation of problems which have been selected for inclusion in this volume. Among these are Morrell H. Cohen, Enrico Fermi, Murray Gell-Mann, Roger Hildebrand, Robert S. Mulliken, John Simpson, and Edward Teller.
