This text has been compiled and edited to emphasize fundamentally important topics in quantum mechanics. This text covers the theory part alone exhaustively to obviate the need for either leading in between the lines or making further library reference. Another distinctive feature of this text is that mathematical details are given in complete detail thus ruling out any additional deskwork. The inclusion or felevant digressions and the completeness of the derivations make this a self-explanatory text which obviates the need for further library reference.
