Abstract

Costa de Beauregard, one of France's senior theoretical physicists, has written a "haute vulgarisation" of modern physics trimmed to a particular point of view. His historical accounts of early physics are marred by an overfacile interpretation. Thus, Newton's laws are presented as spontaneous inductions from a common sense base. His accounts of contemporary physics, however, are well informed and clearly written. The thesis underlying the book is that four dimensional space-time is real and objective and can supply the conceptual basis required to unify relativity and quantum theory. In presenting this he adapts and modifies de Broglie's interpretation of quantum mechanics, considering fundamental particles as essentially nothing but integral occupation numbers in the space-time continuum. With this interpretation of particle phenomena he can defend a species of determinism based on the total symmetry between past and future for elementary interactions, an assumption that has been sharply challenged by developments in particle physics subsequent to the writing of this book. There is little discussion of the philosophical presuppositions or implications of his position.—E. M. M.
