I've read a lot of popular writing for the layman about quantum mechanics and the zero point field, and found this intelligent and interesting. I found the explanations of this difficult to conceptualize idea well done, and it gave a me a bit more of the quasi-mystical than I had bargained for, but it was actually a good thing as I tend toward the straight "scientific" explanations, and this author has a decidedly metaphysical bent. I enjoyed the book, but think that it bis better appreciated if the reader has already had some exposure to quantum physics.
