Tributes to Paul Dirac,

Paul Dirac, who died in 1984, was one of the greatest physicists of the twentieth century. The warm regard in which he was held, both personally and professionally, by his colleagues shines through each of the contributions to this memorial volume. Most of the articles in this book were first presented at the Dirac Memorial Meeting held in Cambridge in 1985, at which many of Dirac's contemporaries and former students gathered together to commemorate his life and work. Some of the more personal reminiscences offer us a unique glimpse of the character of Dirac - who always remained and intensely private person, shunning honours and publicity even when he was widely regarded as one of the greatest sceintists of our time. This volume also contains a biographical sketch of Dirac and studies Dirac's important contributions to physics and mathematics, which should offer valuable summaries for all those who are interested in the history of modern physics and the development of ideas of quantum mechanics in the twentieth century.
