Principles of Quantum Mechanics

Preface

The classical mechanics, so profound and successful in describing physical systems at macroscopic level, cannot do justice to describing systems at microscopic level. This is so because the experiments on microscopic particles put them under additional (and imprecisely known) forces of the probe used, which are really not included in the equation of motion of classical mechanics. And therefore the predictions of classical equation of motion do not tally with the experimental results on microscopic particles. This is not the only setback to a fresher. In addition to this, the experiments on microscopic particles (electrons, neutrons, protons, atoms etc.) reveal that these microscopic objects manifest themselves in (some) form of waves. ...
