Is there a negative or positive tone to this product review? === Title: a classic Review: As an undergrad, I am sorry that I cannot share the perspectives of professionals as expressed below. After initial introductory courses, I got fascinated by certain untold conceptual issues. And one of the textbooks (probably Griffiths) suggested von Neumann had tried to prove mathematically that the classical formulation is just the furthest the formalism can go and we don't have to worry about underlying complexities. Later, Bohm created a formalism which von Neumann "proves" to be mathematically impossible in this book. I bought this book just to find out how the proof goes. But I got stuck with some tedious proofs on Hilbert space (which he calls a "digression"). This part isn't essential but as the braket notation is not used you need to consult this part. I think at least a strong background in linear algebra is required. Definitly not an introductory textbook. Most useful for those who study history of physics. Answer:
(A).
Positive

Is there a negative or positive tone to this product review? === Title: Great book. Helped gain perspective Review: This book had a calming effect on me. I learned of Louise Hay and her writings on an Oprah show that was following up on The Secret by Rhonda Bryne. I ordered the book and began to read it immediately. It has helped me gain perspective and I've learned techniques for dealing with stress and racing thoughts. I've put positive thinking to work and have seen results - which - despite believing in the ideology - still surprised me. Answer:
(A).
