A good book. But I felt that the author sometimes explained concepts in a straightforward language without assuming any prerequisite from the reader, and sometimes he used some ideas which required some basic primer before use. The first half of the book was an easy read for me, but the latter half was relatively difficult to understand. One of the reasons that I can think of is that I have not studied the advancements in Physics after WWII during my school. So I did not have a basic understanding of the concepts.

It is one of those books, which will make you feel intelligent and dumb at the same time, still, definitely worth a read.
