Author goes into too much detail about the wrong things: he goes step by step through the algebra in deriving equations. This is (a) unnecessary because people with bad algebra skills won't be taking QM, (b) takes up valuable space that could better be spent on more material, and (c) there are TONS and TONS of mistakes in it!!!! Don't buy it.

Way too many typo's...most of them are quite obvious and there is no excuse for it...a few errors that may cause problems for someone trying to learn the material...
I have never seen this many errors in a technical book....

This is all mathematics ~ ( not helpful to me or general reader )
