"An excellent text ... The postulates of quantum mechanics and the mathematical underpinnings are discussed in a clear, succinct manner." (American Scientist)

"No matter how gently one introduces students to the concept of Dirac's bras and kets, many are turned off. Shankar attacks the problem head-on in the first chapter, and in a very inform

Those who follow the pack waste days wrinkling their foreheads at the long, winding, historical path through quantum mechanics that David Griffiths leads his unsuspecting followers on. Those who know better skip the foreplay and face the glorious intellectual burden that are the axioms of quantum mechanics in just the second chapter of Shankar.

Shankar's introductory chapter on the mathematics of quantum theory is the best out there. It was my saving grace after getting bogged down in a quantum i

Hands down the best textbook I have ever read. Even though it is aimed at higher level students, I found Shankar much easier and more rewarding to follow than Griffith's Introduction To Quantum Mechanics. Each page follows very logically from the last, which to me is very important.

If you have taken basic courses in linear algebra, Lagrangian/Hamiltonian mechanics and boundary value problems than look no further. Perfect for self study!

Quick Review:
A pedagogical masterpiece.
The author deals with many subtleties, the presentation shines with clarity, the material is wisely chosen and have broad coverage, the physics is always very well-motivated, it is suited for self-study and the exercises are carefully chosen so as to teach something new to the reader. Some exercises teach the reader stuff that are rarely found in popular textbooks.

Detailed Review:
I was impressed from how clear and well-motivated everything is in this textbo

Shankar has an interesting way of approach the teaching of Quantum Mechanics. He clumps all the math needed to appreciate the quantum theory at the beginning: mostly linear algebra. If you can solidly understand the first chapter, it's downhill from there.

Amazing textbook. Hard at first for the novice, but upon re-read afterwards, it becomes clear just how great it is.

math intro is comprehensive, concise and very helpful. the first half of the text (which I have read) is very well written - step by step derivations and explanations of the main features of QM. a good alternate text.

I was looking for some specific information earlier today, and Google failed me. Then I decided to dust off this undergrad textbook, and voila, it was right there.

The best QM textbook evar. Spend the money if you need this data on a regular basis.

It’s hard to say I have “read” this book — I have skimmed it to the end and did a few exercises. However, it is really comprehensive and provides enough learning material for months.

Great book, very clear and easy to follow. Don't be impatient, the beginning chapter on the <Φ|Ψ> linear algebra is essential.
A pleasure to work through.

One year of graduate-level quantum mechanics. This book is deep and extensive and builds ideas rigourously from the ground up. Every now and then, Shankar does tend to describe derivations verbally rather than mathematically, but it's a 600-page book, so this can be excused. I did have to supplement it with Griffiths, especially in the second half (chapter 14 onwards); the trouble with Griffiths is that it is written in such a deceptively intuitive way that it's easy to think all of quantum mech ...more

200 pages in. This is shaping up to be the definitive QM book. I started with Griffiths but I was not satisfied because he doesn't spend enough time building the basics and formalisms you will need. Shankar literally jackhammers bra-ket notation into your head for 100-something pages before he even mentions the postulates. It also has a chapter dedicated to the path integral formulation at the end to set you up nicely for Quantum Field Theory.

This is a fantastic explanation of quantum mechanics, readable at the undergraduate level if you are willing to put in the time and work. Highly detailed, lots of information, well-explained, and even touches on relevant philosophical aspects that some computation-heavy teachers are either afraid to consider or don't care about.

The best introductory text for undergraduate Quantum Mechanics. All the maths required is (nearly ) covered in first chapter and review of classical mechanics of is also there. Presentation is clear and concise in correct pedagogical manner.

The Principles of Quantum Mechanics is an influential monograph on quantum mechanics written by Paul Dirac and first published by Oxford University Press in 1930. ... Dirac is credited with developing the subject "particularly in Cambridge and Göttingen between 1925–1927" (Farmelo).

Topics are explained clearly enough for an advanced undergraduate class but covers more than enough for a first semester grad class. Good to have on hand for reference/review durring quantum II.
