Fundamental Interactions in Physics and Astrophysics: A Volume Dedicated to P.A.M. Dirac on the Occasion of his Seventieth Birthday(3 Studies in the Natural Sciences)

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. The Editors vii Miss Sevil Kursunoglu, Professor Behram Kursunoglu, Professor P. A. M. Dirac, Mrs. Behram Kursunoglu, Mr.
