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.

If you work through this book carefully, you will learn some of quantum mechanics -- a similar subset to what the Feynman lectures would give you, but without the atomic physics. You will learn a lot about spin 1/2 and entanglement of two particles. You will learn about one dimensional Schrödinger and how to solve it in free space and also the harmonic oscillator.You won't learn anything about bosons versus fermions, or anything at all about three dimensional solutions or anything about the Hydrogen atom or nucleus.You will not be able to follow the book unless you understand basic calculus and some of classical physics, such as the formulae for kinetic energy, momentum and the energy of a spring -- basic A level stuff. Though integration by parts is spelled out for you.The book is aimed at quite a low level, it works very slowly and step by step, and it is reasonably rigorous. I particularly like the presentation of entanglement and the non nonsense approach to the interpretation of quantum mechanics. It would be hard to read this book and end up thinking that consciousness, mysticism or wave-function-collapse have anything to do with quantum mechanics.This book leads you to Many Worlds by the back door, without ever making that explicit, but I don't see that as a bad thing. At the moment, it is the only consistent theory out there.There are a very few typos in the text, but rather more in the exercises. The exercises are mainly very easy, but a few are difficult and a few do not make sense at all, because of mistakes in them. A little more proof reading would help here.I read the Kindle version as it is cheaper. It's OK, but a bit of a pain to leaf back to find formulae that are referred to. I much prefer the way this is done in the online Feynman lectures, where formulae pop up in a box when you click on them.Overall, I recommend this book. If you've not done any quantum mechanics before you'll find it pretty hard going, but probably no harder than any of the other books out there and easier than many of them.

Simply superb!

I'm slowly working my way through this, but am far enough advanced to review it, I think. Importantly for any potential reader, it should be pointed out that this book is a mathematical introduction. Though the maths in the examples and exercises is not particularly difficult, it does require some familiarity with matrix algebra, trigonometric functions and calculus. And, unless I'm missing something, the answers to the exercises are not included in the Kindle book.All that being said, it is exactly what it claims to be. A basic explanation of quantum mechanics, with the detail as clear as possible. That the sub-atomic world does not behave like the world we can see and feel is not the fault of the author.So if you read this book, be prepared to use up a fair amount of pen and paper and to undergo a certain amount of head-scratching along the way.

Taught me a lot. Huge inspiration for my own work.

Great read for quantum enthusiasts or people with curious minds, great delivery and service, highly recomemded

The book tries to give an overview of the subject for amateurs, assuming only an understanding of basic calculus, and perhaps vectors. It is not necessarily the easiest book to follow in places, but after advancing through it, one begins to appreciate the way in which it has been taught.The book pairs well with the first book in the series on Classical Mechanics, however, it isn't entirely necessary that one has read that beforehand.Also, don't necessarily expect to be able to be a QM master - but if you wanted to look into deeper introductory texts, it would definitely be much easier having read this. Also, I would say that one should expect to take their time reading this, rather than "barely understanding" it. Generally, the knowledge is all cumulative and depends on a good understanding of everything before it.I love this book, as it has really increased my love of physics and it is nothing like just reading about someone blathering on about "just how weird" QM is. Understanding some of the mathematical concepts may allow you to come to your own conclusions on QM.

Great book, very informative.

It has the best explanation of quantum entanglement that I have encountered so far.

The book begins with simple and accessible language and increases in difficulty according to the theme, without ever losing clarity. In it, many scholars find new themes of mathematics and physics to be studied. The book together with the course that Professor Leonard Susskind and Stanford University make available for free on YouTube (in English) is enough to begin to understand the immensity of this theme that is applied to everything we use in our day to day, both in electronics as in medicine. Anyone who thinks that Quantum Mechanics is only theoretical is wrong. So, don't think twice, buy the book and watch the 10 classes of 2 hours each on YouTube for free and start understanding more advanced books on the subject.

Una excelente y peculiar introducción a la mecánica cuántica, con la participación de Leonard Susskind, uno de los padres de la teoría de cuerdas.El texto es relativamente sencillo, pero riguroso. Hay que tener en cuenta de que libro va dirigido a personas que tengan una cierta formación científica-matemática. Yo diría como mínimo un estudiante de ciencias (física, química, matemáticas) de 2º curso.Se necesita también cierto nivel de inglés. Aunque este libro está traducido, yo la que tengo es la versión en el idioma original. Desconozco si la versión traducida al castellano es buena o no.Las lecciones vienen con bastantes ejercicios, que no vienen resueltos en el libro, aunque hay un página web con las soluciones donde se pueden comprobar los resultados. No recuerdo la dirección de la página ahora, pero no es difícil encontrar.

Mycket bra bok som kräver eftertanke.Ingen snabbläsning
