Quantum Mechanics: The Theoretical Minimum

This book will appeal to people who, like me, have dabbled in many ways with quantum theory over the years and read many books on it but perhaps never before found anything so clear, authoritative, mathematically sound, and free of blather about how quantum theory defies what seems to pass for common sense along lay readers. The mathematical level will challenge readers lacking prior acquaintance with algebra, calculus, vectors and matrices, complex numbers, and classical mechanics, but this is after all the basic toolkit for anyone seeking to get a serious grip on what makes quantum mechanics tick. Apart from that, the humility that comes with advancing age and a wry sense of humor will suffice to carry you through this engaging little book.Leonard Susskind obviously knows the theory as well as anyone, intimately, and has evidently taught it often enough to know exactly know to optimize his approach. He prepares the ground carefully and uses the qubits representing spin as his main running example, which lets him avoid murky issues around particles and waves for most of the discussion. He also works in Dirac algebra from the start, which is far and away the clearest approach for my money and provides a solid base to discuss the respective approaches and main results of Heisenberg and Schrödinger, when he gets that far. I found his treatment far more enlightening than that in volume 3 of the Feynman lectures, where Feynman made a mess of presenting Dirac algebra and failed to motivate either matrix mechanics or wave mechanics with sufficient mathematical or philosophical care.Susskind has properly taken on board the depth of the foundation work needed to present quantum theory intelligibly, so as not to be shipwrecked on the rocks of the paradoxes that lead weaker heads to despair about ever making sense of their challenge to what used to pass for common sense about physical reality. His discussion of states and state vectors, basic principles, entanglement, uncertainty, nonlocality, dynamics and so on is always spot on, with a confident mathematical grip on the issues and a calm refusal to be ruffled by the difficulties they present to intuitive comprehension. His approach is ideally suited to showing how and where quantum logic defies classical logic, how far you can go before deep issues about spacetime need to be confronted, for example by going from discrete sums to continuous integrals, and how little you need to fuss about particle and waves before the new foundations are in place.A modern introduction to quantum mechanics needs to go beyond Dirac's elegant but dated and difficult textbook, both in terms of approach to set things up for new work in quantum computation and high energy physics and in terms of content to touch on such topics as the Bell inequalities, the trials of Alice and Bob, and the creation and annihilation operators of quantum field theory. Susskind does all this with masterly cool, as well as a warm appreciation of the excitement in wait for people who go on to tackle those further topics. Art Friedman has made sure the text remains accessible to plodders like me, though perhaps some of his humorous additions might be trimmed or deleted in future editions of what seems to me to be a core text with a long and glorious potential afterlife.

These series of books are by far my favourite science books. Ever. Having read the classical mechanics book, I was extremely excited when this was released. I would warn though that it is not for the light-hearted. The Theoretical Minimum books are filled completely with equations and if your mathematics isn't up to scratch you wont get past the second lecture.Having said this, if you wan't to start understanding science; real science that is, not like the science of pop science books where you're told a few vague ideas and some rough history. Rather, this book takes you into the mathematical framework of quantum mechanics and allows you to do the calculations and discover the true beauty of the equations.Before reading this book my background in mathematics and physics were as follows: GCSE and AS level maths and physics, had read the first book. I don't think you will struggle to read this provided that you're willing to work fairly hard at understanding what's going on and that you have a working knowledge of calculus and a basic knowledge of matrix operations and knowledge of complex numbers.The book covers a variety of topics and by the end of it you will understand the basics of the Schrödinger equation, general uncertainty, the Heisenberg uncertainty principal, using quantum mechanics to calculate probabilities of certain outcomes and also quantum entanglement and why it's such a strange phenomena. These ideas are not made readily available, you will have to do a fair bit of work in understanding in order to fully appreciate these ideas.It took me about 3 months to read and understand this book and I feel that I have a basic grasp on some fundamental ideas in quantum mechanics. If you have no serious understanding of the maths of physics or have no interest in learning it then this book is not for you. If you do not want to have to think about the ideas presented in order to grasp their importance then this book is also not for you. However if you want an invitation into the world of real quantum mechanical theory then this is the book for you.

I do recommend this book. The authors did a great job in explaining QM in an accessible manner in a lively language. It does contain some mathematical manipulations but nothing too striking. The book has some exercises inside but again, not hard or involving.Overall, I'd recommend this book to a complete newcomer to quantum mechanics. If you have some experience with QM, I'd guess you can skip it safely.If you want to build a good working knowledge of Quantum Mechanics I recommend the following:1) Read this book first, it's a nice introduction.2) Read Dirac's book - The Principles Of Quantum Mechanics3) Read a university level book such as Binney's The Physics of Quantum MechanicsNow, after this you'd have gathered nice grasp of QM. But this ain't enough - go into the applications such as Solid State Physics, Atomic Physics, Nuclear... Only when you've applied the machinery of QM you would "understand it". Not that anyone can.Get the book ( ͡° ͜ʖ ͡°)
