New York W W NORTON CO - INC Publishers entitled Jtfattere e . Lur ilre was first published in 1937 T , FIRST EDITION PUBLISHED IN ENGLISH IN 1939 BY W - W NORTON COMPANY INC 70, FIFTH AVENUE, NEW YORK All rights reserved BINDERY JAM 2 9 1945 990361 PRINTED IN GREAT BRITAIN TRANSLATORS NOTE THE Author has in certain places modified the original French text for the English translation, for the sake of greater cohesion, and has also revised some passages, in order to bring them into accord with the results of later research. Occasional Translators Notes are shown in square brackets. The chapter on The Undulatory Aspects of the Electron has the special historical interest of having been delivered as a Lecture on the occasion of the Authors receipt of the Nobel Award, while that on Wave Mechanics and its Interpretations was given as an Address at the Glasgow meeting of the British Association in 1928. I am indebted to Dr. J. E. Turner, of the University of Liver pool, for assistance with the translation and the proofs, and to Dr. C. Strachan, of the same University, I am indebted for valuable assistance in dealing with the equations and the more technical passages, as well as for reading the proofs. W. H. J. PREFACE THE amiable insistence of my friend Andr George has induced me to collect in the present Volume a number of Studies on con temporary Physics written from both the general and the more metaphysical point of view. Each of these Studies forms an inde pendent whole, and can be read by itself. A slight degree of repeti tion which the reader is asked to overlook has been the inevi table result for on more than one occasion I have been compelled to duplicate a summary of the great fundamental stages of con temporary Physics, such as the classification of simple substances, the investigation of the photo-electric effect and the origin of the Theory of Light Quanta and of Wave Mechanics the subjects are somewhat technical, and I cannot well assume that they are common knowledge. But though the same subject is outlined in several of these Studies, I have tried to take up a different point of view in each, and have endeavoured to throw light on different aspects of the essential problems of Quantum Physics in order to facilitate a grasp of their importance. On comparing the different chapters the reader will observe that, while overlapping, they also complement one another and he will feel the fascination and greatness inherent in the vast structure of modern Physics. And while admiring the vast number and the extreme delicacy of experimental facts which laboratory physicists have succeeded in revealing, and the strange and brilliant concepts devised by theorists to explain them, he will appreciate to what a degree the methods and ideas of physicists have grown in subtlety during recent years, and how great has been the progress from the somewhat ingenuous Realism and the over-simplified Mechanics of earlier thinkers. The more deeply we descend into the minutest structures of Matter, the more clearly we see that the concepts evolved by the mind in the course of everyday experience especially those of Time and Space must fail us in an endeavour to describe the new worlds which we are entering. One feels tempted to say that the outlines of our concepts must undergo a io MATTER AND LIGHT progressive blurring, in order that they may retain some semblance of relevance to the realities of the subatomic scales. Time and Space, in other words, are too loose a dress for the elementary entities individuality becomes attenuated in the mysterious pro cesses of interaction, and even Determinism, the darling of an older generation of physicists, is forced to yield...

LOUIS DE BROGLIE AND THE SINGLE QUANTUM PARTICLE By A. O. Barut We have abundant evidence and testimony that Louis de Broglie deeply cared about the foundations, the meaning, and our understanding of quantum theory in general and of wave mechanics in particular. So, too, did Erwin Schrodinger, along with Einstein, Bohr, Dirac, and Heisenberg. For de Broglie and Schrodinger this preoccupation meant not simply the acceptance of a novel set of rules, but a constant struggle and a search for complete clarity about the way in which the new theory fits into the great classical traditions of an objective physical world view. We may call this a striving for "physical rigor," rigor in reasoning, or intellectual rigor. There is not only mathematical rigor inside an axiomatic system with which everybody agrees, but there is, and there should be, rigor also in our concepts and methods. To this kind of rigor belongs the unity, the economy and simplicity, and the consistency of physical theories; naturally along with as complete and as clear an understanding of phenomena as possible. No loose ends, no proliferation of poorly tested and phenomenological entities, no bending of logic and compromise, and no handwaiving arguments can be tolerated. Unfortunately this kind of rigor seems to be missing in today's forefront of fundamental physical theories, viz. , particle or high-energy physics.

Kluwer Academic

Matter and Light is a groundbreaking book on modern physics written by Louis de Broglie, the Nobel Prize-winning physicist who first proposed the theory of wave-particle duality. In this book, de Broglie presents a new interpretation of quantum mechanics based on the principle of least action, which has revolutionized the understanding of the physical world. This edition also includes a new introduction by physicist David Bohm and is a must-read for anyone interested in the philosophy and implications of modern physics. This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Campbell Pr

This volume contains the long overdue first publication in English of Louis de Broglie's 1924 dissertation "Recherches sur la théorie des quanta" and his 1929 Nobel lecture "The Wave Nature of the Electron."The book should be of interest to experts, students and all interested in the origin and the foundations of quantum physics.

Research on the Theory of Quanta

Minkowski Institute Press

This is a new publication of Louis de Broglie's book Matter and Light: The New Physics. From Aurélien Drezet's Foreword: 
"Historians of physics will find in the book detailed descriptions of the then new discoveries associated with wave mechanics and quantum mechanics... The general public will find in this remarkable book a very clean presentation of the ideas of quantum mechanics. De Broglie was indeed a great scientific writer using all his talent to communicate the beauty of quantum physics without letting the readers be confused by the vague attitude of weirdness that we find unfortunately so often in many presentations of quantum physics"
