The present volume is a compilation of the talks presented at the 1972 Coral Gables Conference on Fundamental Interactions at High Energy held at the University of Miami by the Center for Theoretical Studies. The volume contains, in addition, contributions by B. Kursunoglu and G. Breit, which were not actually presented, but are included as tributes to Professor P.A.M. Dirac, to whom the Conference is formally dedicated. Again this year the theme, style and format of each session was in most cases the responsibility of the section leaders who also cons ituted the Conference Committee. This organization of the conference meant that each section was coherent and essentially self-contained, and as weIl, allowed for spirited panel discussions to critically summarize, and to indicate new directions for future research. This volume is divided into four sections on Constructive Field Theory, and Advances in the Theory of Weak and Electro magnetic Interactions, Cosmic Evolution, and New Vistas in the Theory of Fundamental Interactions. Each section represents a thorough, penetrating survey of one of the most active research programs of theoretical physics. Thanks are due to typists Mrs. Helga S. Billings, Mrs. Jackie Zagursky, Miss Connie Retting, and to Mrs. Norma Gayle Hagan for her industrious supervision of the many programs involved in the conference. This conference received some support from the Atomic Energy Commission and the National Aeronautics and Space Administration.

This volume contains a portion of the presentations given at the session on Laser-Fusion and Laser Develop ment of Orbis Scientiae II, held at the Center for Theoretical Studies, University of Miami, from January 20 through January 24, 1975. This second in the new series of meetings held at the CTS strove to implement the goals professed in the organization of Orbis Scientiae in 1974, namely to encourage scientists in several disci plines to exchange views, not only with colleagues who share similar research interests, but also to acquaint scientists in other fields with the leading ideas and current results in each area represented. Thus, an effort has been made to include papers in each session that discuss fundamental issues in a way which is com prehensible to scientists who are specialists in other areas. Also in keeping with the philosophy of Orbis Scientiae, the major topics each year are to be varied, with the invariant being the inclusion of developments in fundamental physics. The discussions of the current state of the art in lasers and fusion represented in this volume are not only of interest because they deal with newly unfolding branches of physics, but also because of their potential technological and societal significance. The paper by v. N. Lugovoi and A. M. Prokhorov was not presented at Orbis Scientiae II, but is included because of its relevance to the topics in this volume."

This volume contains the papers presented during the Neurophysiology Session of the first Orbis Scientiae of the Center for Theoretical Studies, University of Miami, Coral Gables, Florida. With this first Orbis which met from January 7 - 11, 1974, the Center for Theoretical Studies has inaugerated a new set of annual gatherings devoted to the natural sciences and to problems on the "interface" of science and society. The content of the talks presented ranged over a wide variety of topics in neurophysiology, biophysics and biochemistry. A number of the talks concerned various aspects of the brain and its functions. Recent results were also presented on the physics and chemistry of membranes. The papers in the volume are presented in the order in which they were originally delivered. Special thanks are due to Mrs. Helga Billings, Miss Sara Lesser and Mrs. Jacquelyn Zagursky for the typing of the manuscript and for their efficient and cheerful attention to the details of the conference.

The editors are pleased to submit to the readers the state of the art in high energy physics as it appears at the beginning of 1980. Great appreciation is extended to Mrs. Helga S. Billings and Mrs. Connie Wardy for their assistance with the conference and skillful typing of the proceedings which was done with great enthusiasm and dedication. Orbis Scientiae 1980 received some support from the Department of Energy. THE EDITORS v CONTENTS The Variation of G and the Problem of the Moon. . . . . . . . . . . . . 1 P. A. M.
