The author has put serious work and thought to writing this excellent book. It is a graduate level exploration of quantum theory but it is written very clearly. A background in college level physics and mathematics are necessary of course but the book is so well designed that the reader requires only common sense and persistence to complete the journey. I found some of the insights very illuminating. and most of the mathematical work was clear enough for me to comprehend the logic behind the ideas, not just through the accompanying discussion but through the maths itself.

I am not a physicist nor a mathematician, just someone who is scientifically inclined with a deep interest in quantum theory and this book is a very valuable addition to my library. I highly recommend it. the author in my opinion literally guides you through an excellent exploration of the subject matter.
