E.P. Wigner, one of the leading scientists involved in the early development of nuclear technology, had always in mind its political and social implications. In the 60s persuing his goal of a peaceful open world he began to develop the concept of Civil Defense against nuclear attacks. Looking back one might see this as an alternative to the concept of the Nuclear Shield. The present volume contains a selection of Wigner's writings on this subject. It is annotated by Conrad Chester.

Originally published in 1972, the twelve articles in this volume discuss various aspects of quantum mechanics that owe their origin to the work of P. A. M. Dirac. Each of the distinguished contributors reviews Dirac's work and discusses its development in some detail. Since Dirac's work ranged widely, the resulting volume constitutes a valuable survey of the state of quantum mechanics. A small part of the book contains personal reminiscences of Dirac in Cambridge and of his early visits to the USA and gives a historical account of the development of quantum mechanics during the decade 1924 1933, aptly termed 'the golden age of theoretical physics'.
