Persuasion has ever been integral to the acceptance and understanding of a new theory of hard cracking jaws to many around world including great physicist. This is such a book that such hard theories are being replaced by simplistic soundbites and easily manipulative ideas which takes its rise from the principles of finite difference method requiring the lowest level of high school algebra. Worth mentioning that every step has been clearly and carefully presented with easy calculations and graphical illustrations to the understanding of the layman. Although the new ideas presented herein haven't experimentally proven, it is a faith that every scientist will wish to get to the bottom even if that lies in limbo of obscurity. The layman, beginners, masters to doctorate students of physics will find this book immeasurably valuable and in working order of applications to the study of solid state physics and physics in general.
