Non-relativistic quantum mechanics

the long version

"As the content of physics - or indeed of any science - increases it is necessary to evolve new teaching sequences in order to bring students near to the advancing frontiers by the end of their honours course. This book is an attempt to present quantum mechanics in a modern way, building up the formalism from a set of postulates which emerge naturally from a consideration of a few well-established results of experimental optics and atomic and electron physics. Matrix and wave mechanics then appear on an equal footing, and are used as appropriate to treat the various topics and applications which are selected for discussion. Familiarity with the experimental background of atomic physics is assumed, and the treatment, though concise, is aimed at the all-round physicist rather than the specialist in mathematical physics. The 46 problems are designed partly to illustrate, partly to supplement, the text."
