Introduction to Quantum Mechanics

This book defines Quantum Mechanics which has grown in applications that extend to many areas in engineering and applied science. Since the large part of the complexity of Quantum Theory is due simply to geometry, the concentration in the book is on one-dimensional systems, that present the clear description of some key ideas and revolutionary concepts. The book is a first course where it is much more important to apply exact theory to simple cases than to apply approximate theory to complex cases. Most of the book is concerned with particles without intrinsic spin .
