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.<br><br>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.<br><br>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.<br><br>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.<br><br>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.<br><br>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.<br><br>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.<br><br>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.
