This book contains the proceedings of the Gregory Breit Centennial Symposium. The legacy of Breit to atomic, nuclear and particle physics is discussed vis-à-vis modern developments in these fields. Among other subjects, the present status of the Breit interaction in atomic physics and of the nucleon-nucleon interaction are reviewed. The second part of the book contains a more in-depth presentation of the status of modern nuclear physics, from relativistic heavy ion physics to nuclear structure physics and nuclear astrophysics. The recently confirmed discovery of supersymmetry in nuclei is also discussed.

From its early beginnings at SLAC in the 1970''s, the study of nucleon spin structure using polarized lepton beams and polarized nucleon targets has become increasingly important in nuclear and particle physics, with current experiments at several of the world''s high energy and nuclear physics laboratories (CERN, DESY, SLAC and Jefferson Lab) and with enormous related theoretical studies. The understanding of the fascinating but complicated problem of nucleon spin structure has progressed substantially, but fundamental questions remain and it can be confidently predicted that future activity will be high.The Erice Course on The Spin Structure of the Nucleon covered both the experimental and theoretical aspects of the subject, and this volume includes the lectures given at the School. In many cases the lecture material has been extended and updated by the authors. In addition, several recent publications on experimental work have been added in an appendix.

This book reviews the major physics results from the meson factories, surveys the status of the relevant fields (including pion physics, hadron physics, and electroweak physics), and explores prospects for further progress.
