Quantum Physics: Fact or Fiction? - Author's Introduction

Quantum Physics: Fact or Fiction? - Author's Introduction Introduction to the First Edition Quantum physics is the theory that underpins almost all of our current knowledge of the universe. Since its inception, more than 60 years ago, it has expanded to successfully explain the behavior of subatomic particles, the properties of atomic nuclei, and the structure and properties of molecules and solids. In my study of physics about twenty-five years ago, one of the main reasons for my admiration for quantum was the huge intellectual gap between it and our ordinary way of looking at the universe. We students were at a loss about it, and our teachers and professors had priority in the theoretical application of quantum to explain physical phenomena. It was difficult to find books that discussed the intellectual aspects of this subject; or at least those that discussed quantum problems rationally and fairly. I then had the opportunity to teach quantum mechanics to undergraduate students some twenty years later, and I tried to make some references to the intellectual aspects of the theory and its problems. Although there were many references and sources, most of them were rather specialized books, and they were difficult for non-specialists. As my experience grew, I became convinced that it was possible to explain intellectual problems in quantum theory without requiring a thorough understanding of the vast areas of physics involved, and without familiarity with the complex mathematics that specialists find most useful. This book is my attempt to reach this goal. The first four chapters of this book discuss the basic ideas of quantum theory, and describe its two main problems: The problem of "locality" is that the different parts of a system exchange influence, even when they diverge and even when there is no known communication between them. The problem of "measurement" arises from the idea that quantum systems only have their own properties when they are measured; although nothing seems to fall outside the scope of quantum physics to do this measurement.[1] The following chapters of the book discuss the various solutions proposed to solve these two problems. Each of these solutions in some way challenges our traditional view of the universe, and many of the supplies of these solutions and theories are implausible. There has been no agreement or consensus in this area in general. The last chapter summarizes the different points of view, and I present my own opinion and position. I would like to thank everyone who helped me to write this book, especially Simon Capelin, Colin Gough, and Christopher Isham, who read and critiqued the draft of the book. I have also benefited greatly from the discussions with the audience at one of my lectures at the University of Birmingham’s Department of External Classes on their proposal. I would also like to thank especially "Judy Astle" who has lined up the book and collaborated and persevered on numerous edits and revisions. Alistair Rae, 1984 If it is subject to the laws of quantum mechanics, then the measuring devices will not have their qualities (such as the sound or light of a lamp) unless these qualities are also measured, so where does the chain break? If it is said that it is not subject to the laws of quantum physics, then the theory's description of the universe is incomplete, and this is rejected by most physicists. (Translator) Introduction to Second Edition In preparing this second edition, I aimed to simplify and clarify the research as much as possible (without diluting its content) and to update the body in the light of the scientific developments of the last seventeen years. Chapter III is a good example of these two goals, where we researched the “native” and specifically the “Bill’s Theorem”. I would like to thank Lev Vaidman, who alerted me to the lack of fairness in some of my criticisms of the “many worlds” theory. I also thank him for his and Simon Saunders’ attempts to help me understand how the theory dealt with the “probability” problem. In light of this, I have rewritten a large part of chapter 6; but I don’t think they will agree with me. I also reviewed Chapter 7 to take into account the “Spontaneous Collapse” model developed by Giancarlo Ghirardi, Alberto Rimini and Tullio Weber. We also reviewed some recent important experiments in this area. There has been a remarkable development in the explanation of inflexibility in chapters VIII, IX, and X. While I left chapter 9 almost as it is (where I discussed the prevailing scientific ideas of the 1980s), in chapter 10 of this new edition I have dealt with recent scientific developments since then. This edition has improved greatly, thanks to the guidance and observations of Christopher Thompson and his 1996 editor-in-chief, who read the draft, discussed it, and criticized it with the eyes of the expert philosopher; he must have noted many of his suggestions and amendments. I must also express my gratitude for the useful discussions with listeners and attendance at the annual Physics Foundations conferences held in the United Kingdom. I am, of course, responsible for the mistakes and mistakes that remain in the book.
