This is an advanced undergraduate text with a nice gentle introduction to standard material on beginning quantum mechanics. The first few chapters (1-4) are pedagogically sound though chapter 3 is bit incomplete since it does not fully unravel the connection between classical and quantum mechanics. Poisson brackets could have been more elaborately presented. Each chapter is followed by a fairly large collection of solved problems. Most of these problems serve as useful study guide for tests and routine homework assignments. Chapter 5 on angular momentum is standard material but is little bereft of physical insight. Sakurai's treatment of angular momentum in his introductory QM book is perhaps one of the best I have studied. Chapter 7 on addition of angular momenta including the all-important Clebsch-Gordon coefficients and Wigner-Eckardt theorem is revealed as mathematical constructs with little connection to the physical world. Isospin is the only cited example for C-G coefficients. As the book moves forward, physical explanations take a distinct back seat. Mathematical details get precedence and this is specially true in the chapter about scattering. In all fairness though, the worked examples in the scattering chapter are of a good quality. They helped me understand the subject of quantum scattering and solve test/homework questions. One topic that you will learn rigorously is the Hydrogen atom and its related radial and angular wave functions. The hydrogen atom and the symmetry and parity of its wave functions is the subject of several interesting solved problems in the sections on time-independent and time-dependent perturbation theory and also to some parts of scattering theory.<br><br>Some topics, of considerable importance in theoretical physics research including Berry phase, time reversal symmetry, Green's function, propagators etc are either perfunctorily treated or completely left out. The author discusses about the adiabatic theorem (see QM by David Griffiths for a more lucid introduction) but leaves out Berry phase. Green's function is similarly introduced in the scattering chapter with hardly anything about the need to seek solutions to the Helmholtz equation with an impulsive forcing function. A few extra words about contour integration in this connection will also help.<br><br>Overall a very readable book (the first half is distinctly better) but some parts can be rewritten to offer more insight. More chapters on items of current interest that can be treated under a graduate QM framework must be included (i.e, if a third edition of the book comes out, I hope it does!). Reading this book in conjunction with David Griffiths, A.S. Davydov, Greiner will definitely help. This is from personal experience though. I do not expect everyone to concur. This book deserves a 4.5.<br><br>One last thing: Horrible binding, constant use will split the spine!
