Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
I do not think that this book deserves a negative review despite the silly humor or childish cartoons. This is neither a comic book nor is intended to be, but just in the process of learning of qunatum mechanics things such as these help to avoid the intimidation of reader and keep him sort of hanging around into learning this stuff. This is not meant for experts who may already have patterned a mind set on this subject. This is for a beginning reader who has some background in liberal arts physics and the like and who wishes to know what is really meant by quantum mechanics and why. Experts who might read this may find that the "holes" in their understanding is filled by reading the booka fact that may make them depressed of the idea that they may have thought that they have understood quantum mechanics prior to reading this book.
This book is simply unpretentious, historically structured and focuses on clarity as much as possible while trying to derive all steps in mathematical developmentan important style of presentation necessary to enable a reader to stick to the book rather than a masterful book that author may likely to intimidate a reader while demonstrating his prowess in mathematicsI see this too common in books on quantum mechanics. Advanced QM books are often seem to be written to sort of "impress" members of the subject community that how the author has laboriously done a book masterfully or how deeply he has mastered the subjectThis book is quite different from this styleIt is quite readable, understandable and makes you to appreciate what teaching really is. I do not think there is any other quantum mechanics book that is as simple as this one and easy to understand in one reading, with some calculus background. This type of teaching sytle, from the roots and in a historical context is rarely employed todayI cannot think of any quantum mechanics book that builds every element of the concept from the roots like it is done in this book. When I look at text books, it is all to common to see concepts and facts presented as if they were "invented" in one fly but not developed as an evolutionary development where very bright people have contributed along the way. Although it may not be possible to present material in a historical context in every subject, this book does it admirably well in the important field of quantum mechanicsthe characters including Wien, Max Planck, Bohr, Sommerfield, Born Heisenberg and Schrodinger are all part of this drama and their roles and contributions are well illustrated in cartoons, which I thought was nice. Besides, I do not think that this is entirely written by studentsI think it has been greatly assisted by someone who has worked with Heisenberg (It is remarked somewhere in the text albeit indirectly). I thought the matrix mechanics, the way it is done in this book and in showing its correspondence to Schrodinger's equation is simply awesome ! I am Professor in an engineering department in a major university and I was thrilled to find that this book has employed approches that I have been using in my own classesteaching style and methodololgy is an wonderful artand it needs, first, I think, a sort of fanatic attitude toward simplicity and approach based on reverence to the subjectthe reader may be blessed to discover some of it when you read this book. Hopefully you may discover the ultimate teacher! Richard Feynmann had once reportedly said to his collegue about his lectures in CalTech to freshmen, ".....I couldn't do it (a particular concept) well...not this way...I thought I can make a freshman understand this concept...I could not do it....that means I do not understand myself this concept very well...." The utter honesty of Feynmann is remarkable. Surely Feynmann would have passed a fair assessment of this book as this tries to capture some of his style in his famnous threevolume book on Feymann Lectures of Physics. I strongly it recommend to any beginner who is really interested in understanding quantum mechanics.

Most of the reviewers have already said all the important things to be said for this book, so I will just highlight what I think prospective readers should keep in mind.
1) This book is about twice as hard as "Who is Fourier?," and for laypeople like myself, it doesn't begin to really pay off until you reread it a few times and get truly familiar with the material. Point being, the cartoons are nice and encouraging, but sometimes they have the weird and unintended effect of making you feel stupid because these cute little drawings get it all eventually and do math really well, but, uh, the derivations are somewhat....difficult, for people. 2) The difficulty is not a drawback, per se, but for the most part a sign that these LEX fellows are trying to really get you into the heart of this material, and this material is, after all, Quantum Mechanics. 3) This book may leave your head spinning, unlike the Fourier book, and this is because the Fourier book was able to take its sweet time with pretty much one subject. Here, however, the authors faced a tough one in having to provide readers with clear info. on QM and also imparting the necesary history of physics for understanding the material. But give them credit for doing it at all. So you get swarms of equations from here and there, and then smash them all together and make the classical equal to the quantum, etc.., etc..again, not easy stuff, but manageable. (I also wanted to give the book 4.5 stars, for the same reasons as a reviewer below, that is, for occassional vagueness and underexplanation). 4) Just reiterating, all of the above are only real drawbacks if you skim the book or read it swiftly (if you're a beginner)it is a book that requires patience and study, and it rewards the effort. As the cute drawings say: "You can do it!" Thats itenjoy!

An Excellent Book on Quantum Mechanics,
By Amazon Customer "jinde" (Chicago, IL United States)  See all my reviews
Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
First of all, this is not a serious textbook and is primarily intended for high school students or first and secondyear undergraduates who are interested in quantum mechanics. In fact, one of the reviewers of the original English script is a high school teacher (Dr. David Derbes. Luckily, he is my physics teacher : )).
This book is divided chronologically into six chapters: "What is light"; "early quantum theory"; "the birth of quantum mechanics"; "wave mechanics"; "so long, matrix", and "departure to a new world". As many other readers have said, you will learn a great deal of history of modern physics in this 550page book. You will find plenty of math in this book. Why? The writers of the book are very kind to include the derivations of important formulae. Unlike many other books just tell you the final results/equations, this book actually shows you where the results/equations come from. This is a tremendous help because after seeing the derivations it is much easier to remember and link what you have read into a whole piece, and not end up with a bunch of separate esoteric, elusive equations that lingering in your brain. There is, however, quite some math involved in this book. To read it comfortably, you need to get used to subscripts and superscripts. Math used in this book ranges from simple algebra to advanced calculus (such as Divergence and Laplacian). The good news is, virtually every derivation is shown stepbystep, and the authors try to show you all the required math and conclusion without going too deep into the exact meaning of those math, so it is quite possible to follow even without extensive knowledge in math. That being said, it is certainly helpful if you are good at math and know some of the more advanced math beyond high school level. (For those of you who don't want to go through all those math, I recommend Brian Greene's The Elegant Universe. Although it doesn't contain as much information on quantum mechanics [since it is a book on superstring theory], the part on quantum mechanics is very clear, insightful, and very easy to read.) The only complain I have about this book is that sometimes ideas are not fully explained, in other words, the text tries to explain something to you, but you can't see how the explanation has anything to do with the question you have. An example: early in the book it talks about the idea of "degree of freedom". It says an object has three degrees of freedom, since it can move in three directions (updown, leftright, forwardbackward). Then it tries to convince you that a light wave has only two degrees of freedom. The explanation is that "potential and kinetic energy each has its own direction, which means that waves have two degrees of freedom." But every object can have potential and kinetic energy in two directions, why do they have three degrees of freedom? Ambiguity is the only reason that I give this book four stars instead of five. (I wanted to give it 4.5 stars.) (By the way, light wave indeed has two degrees of freedom, but the reason is something else.) Overall, this is an excellent book on quantum mechanics. This whole book is written in a relaxed style. You will see many funny cartoon faces in this book (which can really make you laugh at times). : )

A truly wonderful adventure,

Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
This is a wonderful book. The evolution of quantum mechanics becomes a captivating adventure story about how scientists struggled to explain the puzzling result of experiments involving light and electrons in the first decades of the Twentieth Century. Reading this book you understand both the essentials of quantum mechanics and why its conclusions contradict our intuitive sense of how the world works.
If you want to understand quantum mechanics starting with little or no knowledge this is the book for you. But even for those of you who are not dying to learn quantum mechanics, this still might be a book worth reading. More and more quantum mechanics does matter. Quantum mechanics provides not only an "explanation" of some of the most fundamental behavior in our world, but also is increasingly a part of our mythology (e.g. the uncertainty principle) and probably of future engineering (e.g. the quantum computer). As wonderful as this book is, I would make a few observations: 1. If you are really serious about understanding the underpinnings of quantum mechanics, or simply think this is the kind of thing you just won't get enough of, start first with the other book in this series, "Who is Fourier?" A fair amount of the mathematics in quantum mechanics relies on material covered in "Who is Fourier?" If you are going to get serious about this you might as well read the books in what would be a more satisfying order. 2. Be forewarned, the style of this book is not that of your typical scholarly book. This is not a weakness; in fact, it provides a warm charm, much the way the odd English in a Japanese video game does. The book is well translated from the original Japanese, but some of the unusual cultural differences remain. In several sections, there are perhaps a few too many references comparing learning science with learning another language. Fortunately, these sections can be easily skimmed. 3. One of the most fascinating results to come out of quantum mechanics is the Heisenberg uncertainty principle. This book does a wonderful job laying the foundation for this principle. The book spends a lot of time going through Schrodinger's equations deriving the formulas for quantum mechanics from the assumption that the electron is a wave rather than a particle. This, along with Heisenberg's particle and matrix basis for determining quantum mechanics, provides the pivotal models for the uncertainty principle. Yet I found the treatment of the uncertainty principal itself disappointingly brief. 4. There seems to be a proHeisenberg bias to the book. The Heisenberg story is at the center of the book, and it is briefly noted that one of the senior teachers at the Japanese school where this book was written was an associate of Heisenberg's. I can't say for certain that this treatment is biased without knowing more of the history, but that is certainly the impression one gets. "What is Quantum Mechanics?" is organized into six chapters. The first chapter discusses the study of light and how the results of the "black box" experiment led Einstein to the conclusion that light could be described as a particle as well as a wave. The second chapter moves the discussion from the study of light to the study of electrons. Bohr's initial model of the atom with electron "circling" the nucleus is derived. The third chapter describes how Heisenberg "squeezed" the discrete behavior of the electron into the equations of motion from classical physics. The fourth chapter describes how Schrodinger took de Borglie's insight that the electron could also be described as a wave to derive the equations of quantum mechanics. The fifth chapter describes how Schroidinger ultimately failed to provide a visual image for the behavior of the electron. The sixth chapter brings us to where we are today with Bohr's probability view and Heisenberg's uncertainty principle. All in all, this book is an absolute pleasure.

An excellent walk through of Quantum Mechanics from scratch.,

Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
This is a very good and unusual book about Quantum Mechanics that appears to be aimed at a fairly young audience. The book does not gloss over difficult topics. It explains the difficult mathematics step by step rather than playing that ageold game of, "I'll write my book so that I can impress my colleagues with its abstruseness", which happens on occasion. It is Japanese in origin and almost has the feel of Manga (popular graphic novels), however, it covers the topic well. This would be a great book for "anyone" who really wants to be lead step by step through the historical development of Quantum Mechanics as well as the fundamental mathematics involved. If you are the type of person that really would like to understand the basis of this important subject, buy this book. If you are the type of person that wants to look "smart", and spend an extra several years trying to wade through many books that aren't as clearly presented, by all means, skip this one.

The coloring book of quantum mechanics!,

Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
Believe it or not, I actually recommend this book for my graduate quantum chemistry class in addition to a "regular" quantum text. I have probably pulled more lectures out of this book than any other source. Its pedegogy is
questionable and a cheeky. And, yes, the stupid cartoon icons are very annoying. Now, why do I like this book: first of all, most chemists are mathphobes and by in large enter graduate school poorly prepared in both physics and math. So, the icons, cartoons, etc help lower the barrier towards understanding and utilizing the necessary mathematical tools required to study QM. Secondly, the overview of the historical dialog and development is quite fun and puts an interesting spin on the classical and semiclassical underpinnings of quantum theory. For certain, if you want to be serious student of QM, go to the classic texts. If you want to have fun, read this book along side and bring your crayolas.

What a Good Book!!,
By "elmaguro" (Cuernavaca, Morelos, Mexico.)  See all my reviews
Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
This is completely a great adventure in Quantum Mechanics not just for the intrepid students of TCL but for me. I started reading this book knowing anything about the theme and once I started reading just couldn't stop. The style they use to write is very natural and easy to understand, you don't need to be a teacher to read this. I've read before "Who is Fourier?" other book of TCL and when I found this book I decided to read it thinking would be as interesting as Fourier, but I was wrong, this is better.
I WOULD STRONGLY RECOMMEND IT TO EVERYBODY EVEN IF YOU DON'T KNOW ANYTHING ABOUT PHYSICS. I learned that Quantum Mechanics or any other topic don't have to be diffcult to understand, the secret is the way you approach to it. I'm eagerly waiting for another adventure to come. It's a book you'll enjoy from the begining to the end.

Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
Sorry, but all the childish chatter is annoying. Too wordy about trivialities, hardly any explanation of the hard stuff. We are presented with big equations with no definition of the unfamiliar symbols, and are expected to get it through osmosis and repetition.
Incorrect statments are presented as facts, to be later modified or corrected (sometimes). Sloppy language, as when electrostatic force is called magnetic. No mistake, the subject matter is heavy stuff, but this presentation won't get you to the desired understanding, only to a wideeyed, childish "wow!" I much prefer reading Gamow, Hawking, Weinberg, Feynman, and others, even when they use few equations. What good are the equations that are not supported by adequate explanations or even definition of terms?

Excellent stepbystep introduction to QM,

Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
It's refreshing to find a physics book that takes the reader through the derivations stepbystep without making any "quantum leaps" that the reader is assumed to follow implicitly. I also liked the "what we've learned so far" summaries at the beginning of each chapter. The book is very valuable for these reasons alone. Although the stories about the people and history of quantum theory were great to have, I was somewhat annoyed by all the silly conversations and digressions of the students  the book could have been a lot shorter without these. Also, I think the book could have used more diagrams of wave propagation in order to help the reader develop an intuitive feeling (if that is really possible in QM).

An excellent INTRODUCTION to Quantum Mechanics ...,
Ce commentaire est de: What Is Quantum Mechanics? a Physics Adventure (Paperback)
After three attempts over the past two years I finally finished this book. The text is an excellent introduction to Quantum Mechanics but DOES require some mathematical ability. Often I would get lost in the derivations. However, on the second and third attempts things begin to make sense. The text does show all the steps involved in the derivations and that helps. You could skip the math but then the book loses it's value and you will not get much out of the text. If you are formally trained in Quantum mechanics this book will serve as a review. However, if you, are just curious, this text is great. Be prepared for a tough read.
