This book is not a manual. It is consisted of a collection of stories and articles about possible time travel incidents, such as the Philadelphia experiment and other like occurrences: no new information.If you already have some understanding of how the relativity theory of a space-time continuum replaces the Newtonian concept of an absolute time and space, then this book is not for you. It is for people who want to acquire this knowledge. It is for beginners.So, unless you are an absolute beginner to new science, do not waste your time and money on this book.I do laud the editor for his effort nonetheless.
