Product Description
This book first teaches learners how to do quantum mechanics, and then provides them with a more insightful discussion of what it means. Fundamental principles are covered, quantum theory presented, and special techniques developed for attacking realistic problems. The book's two-part coverage organizes topics under basic theory, and assembles an arsenal of approximation schemes with illustrative applications.

 Great supplemental book, 2008-11-16
My Prof. uses Shankar, but he isn't very clear sometimes. I bought Griffiths to compliment, and I find his order of introducing things and way of explaining things much more clear. I reference it regularly.

Decent..., 2008-09-23
Being an undegraduate and having to take a quantum mechanics course isn't easy, especially being that the class is made up of some graduates and some undergraduates. The professor isn't exactly adept at explanations either, which makes things quite difficult. However, this book thus far is making my life easier. Griffiths gives a good mixture of "lecture" and examples overall, though the problem sets can be confusing. Some concepts aren't exactly introduced during the text and that makes things rather difficult. At least, it does in my opinion, but I'm an undergrad who isn't really adept at knowing what to do immediately. That, and theory isn't really my cup of tea. But I digress...
The format flows easily, and the text itself isn't too confusing to read. Not too shabby.

Undergraduates, search no farther. Here is the BEST QM book., 2008-08-12
As an incoming freshman into an undergraduate university, I have read a few books on quantum mechanics, particularly those by Liboff, Fitzpatrick, and Sakurai. For the absolute beginner in quantum mechanics, I must say that this is the best book that I have ever found. In all ways, it succeeds:
- The author presents the text in a conversational style.
- The material and examples are concise, yet perfectly relevant.
- The problems in the book are of varied difficulty, and stars next to the problem narrate the difficulty. Problems of harder difficulty are usually supplemented with hints.
When I tried using Liboff, Fitzpatrick, and Sakurai, Fitzpatrick was effectivly useless, Liboff provided a decent overview, and Sakurai went very deeply into mathematics (too much for the undergraduate). So, if you're looking for an introductory book to QM, this is the perfect book for you! Just make sure you are familiar with concepts like calculus (obviously...), differential equations (again.. obviously...), and linear algebra. Even then, for linear algebra, Griffiths has a section in the back for this.

The Best Introductory Text!, 2008-04-22
This book literally saved me in quantum mechanics. Between my professor's willingness to help introduce us students to many of the challenges faced by quantum theory today and this book's ability to quickly and painlessly explain many of the concepts behind QM I actually enjoyed learning this subject.
The book not only has great explanations of numerous concepts essential to QM but always supplies one thorough example of a calculation relevant to each of these topics. Some of the problems in the book were a little difficult however. Particularly, I remember searching for hours through integral tables before I found the integral I needed to solve one of my assignment problems. That was a huge waste of time. But still, this book will set the necessary groundwork for whatever kind of understanding of QM you can manage.

Good introductory text, 2008-01-03
This book will take you through the core topics on quantum mechanics. As a confirmation of the author's statement that quantum mechanics is conceptually rich (p. vii) this book indeed introduces you to topics encompassing but no limited to thermal physics, statistical physics, solid state physics, chemistry, optics, astrophysics, that should give you an indication for its wide spectrum of applications. You will encounter a wide gamut of familiar physical concepts here such as Bohr radius, Rutherford scattering and lasers.
The text is well explained and easy to follow, the problems are doable. Be prepared for the math though. Before reading this book I suggest that you do groundwork on engineering math comprising functions of a complex variable, series solutions of differential equations, probability theory and linear algebra. There is one thing I can't get from books on quantum mechanics including this one: an elucidation on the development of the Schroedinger equation.
This book will serve you well in preparing for a more advanced reading in quantum mechanics. I personally find it indispensable in being literate in texts about semiconductor physics, opto- and microelectronics.
Update: PS. Recently I've been told by a physicist that the Schroedinger equation is taken as a postulate without proof.
It appears I have overused the book as evidenced by its having gone out of binding.
