"… a good addition to the existing literature on the topic. The emphasis is put on the very special correlations that this theory makes possible: They are forbidden by very general arguments based on realism and local causality. Quantum mechanics, science dealing with the behavior of matter and light on the atomic and subatomic scale. Nature doesn’t need the theory of quantum mechanics. However it is difficult to interpret, and philosophical contradictions and counter-intuitive results are apparent at a … The original author, J. J. Sakurai, was a renowned particle theorist. In contrast, I think this strategy may be the weakest trait of the book; this may just be a question of personal taste, but I always find that "neutral" books like this one leave something to be desired. The emphasis is put on the very special correlations that this theory makes possible: They are forbidden by very general arguments based on realism and local causality. Also: "it didn't take long before it became clear that the completely undulatory theory of matter also suffered of serious difficulties, actually so serious that physicists were soon led to abandon it." The 13-digit and 10-digit formats both work. Give as a gift or purchase for a team or group. A starting point is to acknowledge that understanding quantum mechanics requires us to operate in ordinary consciousness. In this review, though, I wish to primarily discuss the main strategy the author uses. Do we really need another book on quantum mechanics? Ideal for researchers in physics and mathematics. The book is ideal for researchers in physics and mathematics who want to know more about the problems faced in quantum mechanics but who do not have specialist knowledge in the subject. So, to conclude, while I find Laloë's book to be an extremely valuable contribution to the foundations of quantum mechanics for its completeness and clarity of exposition, I still find unsatisfactory its lack of an opinionated discussion and evaluation of the different alternatives. This article presents a general discussion of several aspects of our present understanding of quantum mechanics. Reviewed in the United States on July 10, 2016, laloe is very good physicist and his book is excellent as well. The book has eleven Chapters and several appendices, through which the author goes from the history of quantum mechanics to its interpretations, passing through the Schrödinger cat, the Einstein-Podolsky-Rosen (EPR) paradox and Bell's theorem; quantum entanglement and its application; and a solid mathematical introduction. The premises of the theorem and the the logic of the argument are made extremely clear and straightforward, something rarely found in the literature. Do we really understand quantum mechanics?. A starting point is to acknowledge that understanding quantum mechanics requires us to operate in ordinary consciousness. As a result, this kind of book often disregards technicalities and focuses primarily on the problems of interpreting the formalism and on the possible realist interpretations of the theory. Neurofeedback 101: Rewiring the Brain for ADHD, Anxiety, Depression and Beyond (wit... Franck Laloë is a Researcher at the National Center for Scientific Research (CNRS) and belongs to the Laboratoire Kastler Brossel at the Ecole Normale Supérieure. There's a problem loading this menu right now. By a causal explanation I do not mean a formal description as we get it from Quantum mechanics; but a physical explanation where the cause of this phenomenon is visible. [ … The quote, exact words, "If you think you understand quantum mechanics, you don't understand quantum mechanics." Additional gift options are available when buying one eBook at a time. While his reasons for rejecting the latter view are the traditional ones and therefore not controversial, in my opinion his reasons for rejecting the former are too hasty. His goal is explicitly to understand the foundations of quantum theory which also, by his admission, is something that has been neglected in the majority of traditional physics books on the topic. Do we even understand quantum mechanics? Franck Laloë, Do We Really Understand Quantum Mechanics?, Cambridge University Press, 2012, 406pp., $75.00 (hbk), ISBN 9781107025011. But if instead another "interpretation" is believed to be the correct one, the importance and the role of measurement in this theory will be fundamentally different than in the previous one. Gives an overview of the quantum theory and its main interpretations. Read reviews from world’s largest community for readers. --This text refers to an out of print or unavailable edition of this title. Sometimes the treatment is a bit light, and I disagree with F. Laloë when he affirms that Everett Many-worlds interpretation remains non-local. Cambridge University Press; 1st edition (August 30, 2012), Up to 4 simultaneous devices, per publisher limits. While I happen to agree with Laloë's conclusion, the issue cannot be dismissed that quickly. Abstract This article presents a general discussion of several aspects of our present understanding of quantum mechanics. book. Quantum mechanics is a very successful theory that has impacted on many areas of physics, from pure theory to applications. It is ideal for students, researchers, and philosophers of science interested in quantum physics Indeed, I find it misleading that these alternatives are actually called "interpretations"; each of them provides a distinctive picture of reality and because of this each of them should be called "theory" instead of "interpretation." If we leave the question of ontology at the end, one may be led to believe that all theories have the same problems simply because they have the same -- or similar -- mathematics (the state vector, the Schrödinger equation and so on), and this would be a mistake. Surprisingly enough, Franck Laloë has shown us that there is still room for another valuable contribution Laloë provides us with a great addition to the abundant (sometimes even redundant) literature. Do we really understand quantum mechanics? Recommended.".

He is co-author of Quantum Mechanics, with Claude Cohen-Tannoudji and Bernard Diu, one of the best known textbooks on advanced quantum mechanics. Of course it isn't. He starts off with the (commonsensical but vague) pragmatist approach, continues with the statistical interpretation (the view that the quantum description only applies to ensembles), moves to Rovelli's relational interpretation (the state vector depends on the observer), to the algebraic approaches and quantum logic, continues with d'Espagnat's veiled reality interpretation (according to which reality is only marginally accessible to us).

So, what seems to be missing, indeed, is a book that combines these two extremes: a book that cares about conceptual issues but at the same time provides enough mathematical details to enable the reader to understand and judge for herself even the more densely technical material. When in chapter 8 Laloë claims that the notion of measurement is important in quantum mechanics, what does he have in mind? QM is our current understanding of how the physical universe works. I learned Quantum Mechanics years ago in his very good textbook written with C. Cohen-Tannoudji and B.Diu, and it is always a pleasure when people acknowledge the serious philosophical or conceptual difficulties met with quantum physics. The book concludes with a comprehensive and clear mathematical review of the various elements of quantum mechanics. Full content visible, double tap to read brief content. Therefore, I find particularly odd that the chapter on interpretations is left at the end of the book. Quantum particles follow a different set of laws—laws which, to date, we still do not fully understand. On the one hand we find technical books (for instance Sakurai, or Messiah), while on the other we have introductory books (Albert, Maudlin, and Ghirardi). The emphasis is put on the very special correlations that this theory makes possible: they are forbidden by very general arguments based on realism and local causality. Not having a clear grasp of its foundations, writes Laloë, makes quantum mechanics a "colossus with feet of clay" (p. xi): how can we properly understand the theory and its implications if we do not understand what it is grounded on? It remains a very good introduction to the subject though. Laloë wants to provide a balanced and comprehensive view of the foundations of quantum mechanics; he does not want to give preference to one interpretation or another, to one strategy to another, but rather he wishes to analyze how each of them relate to one another and what their mutual relations and differences are. Laloë's book seems to show that finally the situation has started to change. It is ideal for researchers in physics and mathematics who want to know more about the problems faced in quantum mechanics. [Franck Laloë] -- "Quantum mechanics is a very successful theory that has impacted on many areas of physics, from pure theory to applications. Assuming that I have the means to understand and judge the material independently (which this book is able to provide), I'd rather read a heavily opinionated and provocative book than one in which all the options are stated with an impartial and unbiased attitude.

In other words, taking a particular view to be the case will have consequences: in particular, one view will lead to certain problems, another view to others. Use the Amazon App to scan ISBNs and compare prices. While this approach is extremely valuable in making the conceptual problems crystal clear, its danger is that the philosopher, when confronted with particularly challenging technical material, might still be unable to get around it and arrive at the correct conclusions without being obfuscated by the mathematical detail. Copyright © 2021 Notre Dame Philosophical Reviews As Einstein once reminded us, it is the theory that decides what is being measured. This admission, made by a physicist, is rare and frankly refreshing. Laloë's book seems no exception to this rule. Learn more. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. In fact he writes that his book provides a "balanced view of the conceptual situation" of quantum mechanics (p. xiv). Chapter 6 is devoted entirely to the purely quantum property of entanglement, including a discussion of origin of quantum correlations. The second edition includes recent state-of-the-art research, new interpretations, and further references. Because of this, it has inevitably attracted many writers, both physicists and philosophers. The claim that "no one understands quantum mechanics" is often attributed to Richard Feyman, who said that to illustrate the perceived "randomness" that is at the heart of quantum mechanics and the Copenhagen Interpretation of QM.
