1 stars (Typical Griffiths Drivel) - As usual, Griffiths replaces formalism and math with hand waving nonsense. While that may work to some extent in E&M, it fails miserably with a topic such as quantum mechanics. Also, as others have mentioned, Griffiths leaves a good chunk of the actual learning to exercises, which would be fine if there were answers in the back to select important problems or *gasp* a solutions manual, but Griffiths lacks both. Save yourself the grief and buy someone else's book. Griffiths, as usual, just doesn't cut it. 5 stars (Book Review) - excellent book for studying QM with a very comprehensive set of highly instructive problems. 1 stars (Terrible book to learn from QM) - I decided to refresh my QM skills and decided to buy Griffith....bad idea. At the university I used Messiah, B.H. Bransden - C.J. Joachain and Cohen - Tannoudj. All these manuals are much more better than Griffith. If you are not following a course don't buy this book, everything is an exercise, it is interesting to prove your skills and awarness on the matter, but every real stuff is left as an exercise then no explanation at all: for example Ehrenfest theorem and all the mathematics used in Schrodinger equation...these as a starter.... I really don't understand the love for this book, probably as the author tells you QM with an hippy style...if you don't believe me go to the author site.... If you want to learn QM start with Feynman and Greeinstein then read Bransden or Liboff if you are at an undergraduated level otherwise go to Cohen or Sakurai. ...
