This book is not a popular physics narrative meant to inspire people about concepts.  It is something far more useful.  It is a real down to Earth look at the mathematical basis one must have in order to actually work with systems that are effected by quantum mechanical phenomenon.  This book doesn't pretend that quantum physics is immediately attainable and that anyone who can read a book can go and accurately explain things like the quantum limitations on the size of silicon transistors.  I liked this book because it is up front about the work you must put in to understand the mathematical language and established physical theories which describes how things interact in our Universe, so that we aren't all just adding to the confusion.
