He has given most of the necessary derivations as exercises, which makes it unsuitable for beginners. Seems very erratic, irrational, and sometimes illogical in its approach. I never found it to be trustworthy. Though I've read it from cover to cover, I consider it as 'abandoned'! This book seems to be pretty good to many people but I found it otherwise. It never added anything but very little to my understanding.

For example, Griffiths takes his time to explain standard deviations, separation of variables, and phase and group velocity in the beginning.

This makes the book very accessible. The bad: While a step by step calculation makes it easy to follow, one often gets lost in details and misses the big picture. This is not helped by the fact that the book shies away from the math of QM: linear algebra and the concise Dirac notation, which is introduced but quickly discarded. The author takes the shut-up-and-calculate approach to the extreme like how standard freshman physics textbooks present QM.

The formalism is not developed logically, and, overall, the book is very weak in formalism. The many subtleties of postulates are never spelled out. Compare this to e. Symmetry and change-of-basis transformations only make a brief appearance as 2 and 3-star end-chapter problems which, according to the author's rating scheme, are difficult or peripheral problems and even there he still doesn't tell you that they are unitary matrices!

The use of the word spinors interchangeably with two-element column matrices does not help in the slightest. Two-element column matrices are two-element column matrices. Spinors are related to representations of rotation groups, to which Griffiths makes no connection. He also makes degenerate perturbation theory looks complicate, whereas in fact it is just diagonalizing the degenerated submatrix. In conclusion, it seems that everything involving matrices is so badly treated that this book should be called Introduction to Wave Mechanics.

I used this book for an undergraduate course taught by an excellent professor. He made up all the problem sets. So I can't judge the quality of problems in Griffiths. I can recommend it to an absolute beginner, but with the caveat that this cannot be your last QM book if you want to understand QM. Griffiths prepares you in wave mechanics for e. A very nice second book explicitly aiming to clear up the conceptual understanding of those who just finish this kind of "wave mechanics" course is Isham's Lectures on Quantum Theory: Mathematical and Structural Foundations.

I thought the introduction of the bra-ket notation was justified by the clarity it provides. Nov 06, Robert Schinaia rated it it was amazing. I used this textbook when I was taking quantum mechanics classes years ago, and it is the best textbook I have ever read. This book differs from most other quantum mechanics textbooks in that it ignores the historical development of quantum mechanics, and jumps straight into the mathematical formalism the reader is faced with the time-dependent Schrodinger equation on the very first page!

In the first five chapters of the book, Griffiths explains the basic concepts of quantum mechanics. Chapt I used this textbook when I was taking quantum mechanics classes years ago, and it is the best textbook I have ever read. Chapter 2 was particularly interesting to me because it explains how to use the time-independent Schrodinger equation in one dimension for various potentials - e.

The treatment of quantum tunnelling using the Delta-function potential is beautiful. Chapters 4 and 5 apply the Schrodinger equation to three dimensions and in spherical coordinates, and then introduces the hydrogen atom, angular momentum, spin, two-particle systems, and quantum statistical mechanics. The second part of the book chapters 6 to 12 deals with the applications of quantum mechanics.

I particularly loved the sections on perturbation theory time dependent and time independent , and the Variational Principle. Although there is a lot of mathematics in this book quantum mechanics is a mathematical subject , Griffiths does not give complete derivations for everything. For example: he simply presents the Laplacian in spherical coordinates and refers the reader to Boas for a complete derivation. Similarly, Griffiths simply introduces, without explanation, the associated Legendre polynomial when deriving the solution to the angular equation in chapter 4.

But I didn't find this to be a problem; quantum mechanics is complicated enough without the burden of having to derive every detail. However, to get the most out of this book, it is essential that the reader works through as many problems as possible a solutions manual is freely available on the internet.

Introduction to Quantum Mechanics

You might think that you have understood a particular concept but, without consolidation through practice in problem-solving, this understanding can slip away. Working through the problems requires a lot of work and time, and this is the only way to learn difficult concepts. I still use this textbook as a reference in my professional life. In summary: an excellent book that requires a lot of work.

Introduction to Quantum Theory - Chemistry LibreTexts

The title promises exactly what the book is in every way. If you have an good understanding of Quantum Mechanics, then this book is not for you. Griffiths is able to This book is incomplete…. Now that is what I call a good teacher. In this derivation we find out ourselves that it is incomplete and does not fully describe the particle and there is additional angular momentum that cannot be described through Diff. With what acts like the rotation of the earth but not really because it can only take certain values, called Spin. It turns out that this, Spin, is the most intrinsic quantity in quantum itself.

Which leaves the subject perfectly teed up for Sakurai to more fully explain.

Modern QM is written in terms of bra-ket formulation to more fully describe the subject. However, in my opinion, the average student is not ready for it and needs to be weaned of the classical world rather than pushed into the ocean and told to swim. Also, books that start with spin and use bra-kets often reference solutions to derivations in this book when describing wave mechanics without deriving it themselves.

This is really an argument of education and not QM because the bra-ket method wins for actual physics. I am just not sure it is the best place to start when you first learn the subject.

There's no better quantum text than this. With humor, intrigue, and adventure through the dark and creepy paths of quantum queerness, Griffiths has a rare talent but for Atkins, I've never seen it before for being able to match the incomprehensible microworld with neural weirdness of the macro that makes the topic comprehensible. He wonderfully prepares the student Praise to the heavenly vault!

He wonderfully prepares the student, most of whom greet quantum like a taser or a train. On page 1 he puts the student at ease with quotes from the masters. So relax, kid. Nobody gets it. You won't either. Just learn how to turn the crank and steer the wheel. This old jalopy will take you where you want to go without knowing what's under the hood. Nobody knows what's under the hood. Once you get to where you're going, Griffiths tells you what quantum means in the last chapter. If you read this chapter in public, hold your shorts up, it might scare the pants off you.

About the author J. This presented a considerable problem to classical physics as it predicted that accelerating charges emitted radiation. It would thus seem that the energy orbital would be unstable as the electron would slowly spiral towards the nuclei as it emitted radiation. There was no classical model which could explain stable electron orbitals.
