LEARN QUANTUM MECHANICS AT WARP SPEED!
Now anyone can master the basics of quantum mechanics -- without formal training, unlimited time, or a genius IQ. In Quantum Mechanics Demystified, physicist (and student-savvy author) David McMahon provides an effective and illuminating way to learn the essentials of quantum mechanics.

With Quantum Mechanics Demystified, you master the subject one step at a time -- at your own speed. This unique self-teaching guide is filled with solved examples throughout, and offers problems to try at the end of each chapter to pinpoint weaknesses. A final exam serves to reinforce concepts covered in the entire book.

This fast and entertaining self-teaching course makes it much easier to --

  • Master serious quantum mechanics in easy-to-follow steps
  • Cut through the jargon and learn how to do quantum mechanics using worked examples
  • Reinforce learning and pinpoint weaknesses with questions at the end of each chapter and a comprehensive final exam
  • Learn about Schrodinger's equation, one dimensional scattering, Hilbert space, and the density operator
  • Find extensive explanations of spin and angular momentum, vector spaces, matrix mechanics, the harmonic oscillator, and the hydrogen atom
  • Perform better on qualifying or placement exams
  • Take a "final exam" and grade it yourself!

Clear enough for beginners but challenging enough for those who already know something about advanced physics, Quantum Mechanics Demystified is the best self-teaching tool you can find!

If this book didn't have LITERALLY at least one mistake on every page, I'd give it 5 stars. As it is, I have to spend half my time correcting the book. You should see how many things I've crossed out in mine. And the mistakes aren't just using p instead of rho (although there are plenty of those). Some fundamental equations that you need to know are given incorrectly. I'm only about 3 chapters through, but I can tell you that one of the answers to a problem in the Chapter 2 quiz is just plain wrong. (Number 7 - While dp/dt does equal 0, j(x,t) does not) You MUST have a strong grasp of physics and diffy q's to be able to get through this book. I'm giving it 3 stars as opposed to less because I find that I actually do end up with a good grasp of the material I just read, so it seems to be working.

The glutted market for books on quantum mechanics populates a phase space where quality, utility, clarity vary greatly along with scope and breadth. This little book surprised me when I saw it. I purchased it and immediately worked through it and I was impressed. This author seems to establish a whole new paradigm, one based upon practical pedagogy. Instead of trying to impress the reader by showing he can solve complicated problems, the author impresses the readers that they can solve the problems. There is a consistency and uniformity to the presentation. Central concepts are reinforced through repetition. How I wish I had this volume when I went back to graduate school. After you complete the volume, you find that you have a tight grasp on the basic concepts of quantum mechanics. The author has impressed with his ability to convey the rudiments so clearly. I have tried to put my finger on his specific innovations. One that springs to mind is his presentation of the Bessel functions which have been hashed and rehashed. Here the author separates the functions into odd and even parity states. So by nudging us to a different vantage point, we gain a fresh perspective. This book will not replace the venerable Schaum's outline as a collection of practise problems; instead it is a book that students can use to teach themselves. I recommend this book at any time: before a first quantum physics course, during the course, between undergraduate and graduate physics, and as a refresher. Quantum Mechanics Demystified is a nice teaching aid that builds confidence. I hope that the other will attempt to work his magic on a follow-up volume on advanced quantum theory and yet one more volume on quantum field theory.

This is a book unlike any other I could describe. The clarity and conciseness are to be highly commmended. The material is some of the clearest I've seen on this subject. It begins topics at a point that don't leave one feeling like there is a lot of hand waving going on and yet is not overly verbose either. Short of five stars because there are COUNTLESS silly errors in both the worked out problems and the included quizzes.

I'm taking a Continuing Studies (evening) QM class taught by Leonard Susskind at Stanford. David McMahon's QMDm book is the most detailed and helpful review the mathematical structure of QM I could find. His very many, fully-worked out math examples are unique in published form. You cannot begin to get your head around QM without doing the math drills and getting familiar with bras, kets, eigenvectors, eigenvalues, operators, states, Pauli matrices, and so on. Yep, there are many typos, but discovering and fixing them became just some extra homework! It has been about forty years since I last studied this material. Struggling with the excellent Dirac "Principles of Quantum Mechanics" was too big a jump for me without McMahon's help. Understanding QM without the matrix math is like listening to a baseball game without understanding numbers. Learn the "numbers."

Its very difficult to find a quantum mech. books that is enjoyable to read while learning. This is a good book for someone who is looking to understand the basic concepts, especially for people who had some trouble with the usual Shankar, Cohen-Tanoudji, Sakurai, Merzbacher, etc. . . This book is clear and shows many examples to explain the topic. Would have given 5 stars but there are many many "typos", (for example, pi instead of hbar). Would be great it they printed an updated edition in the future. Would be a waste not to perfect such a great book.

Highly recommend this book as a studying aid along with the usual QM course textbook

I got this book initially because it was cheap. I expected it to help me with a problem or two in my upper division QM course and nothing more. Instead I found a wealth of information geared towards letting me know what the hell is going on in as direct a way as possible. The simplest example, and one I feel incredibly stupid for not understanding quicker, is the explanation for all the digging around after eigenvalues and eigenvectors that we were doing. In one paragraph, clarity!

The end result of this book for the quarter was an A, and an easy A at that. I cannot wait for the second addition. Seriously, I can't, the next quarter starts in less than a week! Get that book out as soon as possible Mr McMahon!
