This book gives a comprehensive treatment on the historical discoveries and scientific developments concerning the Universe at the atomic and subatomic levels. Discussions begin with classical discoveries on the behavior of the atom to Quantum Mechanics and ends with exciting modern discoveries that are leading us to unlocking the hidden mysteries of reality. "Quantum mechanics describes the behavior of very small objects - the size of atoms or smaller - and it provides the only understanding of the world of the very small. In the world of quantum mechanics, the laws of physics that are familiar from the everyday world no longer work. Instead, events are governed by probabilities. During the time of Newton, it was thought that the Universe ran like clockwork, wound up and set in motion by the Creator, down some utterly predictable path. Newton's classical mechanics provided plenty of support for this deterministic view of the Universe, a picture that left little place for human free will or chance. Could it really be that we are all puppets following our own preset tracks through life, with no real choice at all? Most scientists were content to let the philosophers debate that question. But it returned, with full force, at the heart of the new physics of the twentieth century." In Search Of Schrodinger's Cat - John Gribbin In addition, the various interpretations of quantum phenomena has led scientists and philosophers to a real possibility of finding a connection between matter and consciousness. This book contains no advanced scientific concepts, and no complicated formulas are written down for analysis. However, it does present some simple mathematical related examples in the final chapter. This is presented in order to reinforce the important ideas in QM and maintain a clear understanding of its fundamentals. It is not assumed that the reader has an understanding of Quantum Physics. Therefore the text provides the reader with enough historical and scientific information to insure his or her confidence in understanding the properties and behavior of quantum particle/wave elements.
