A great review of physicists' attempts to discover what space is, focusing on the concept of non-locality, sometimes referenced as quantum entanglement. The author does a historical review of action at a distance in the introduction, spends a chapter or two describing non-locality and the debates in the early part of the 20th century, and devotes the rest of the book to discussing advances over the last several decades.
He makes it clear that I can never hope to understand the deeper issues, but his presentation is quite lucid and with a fair amount of humor. The footnotes and bibliography occupy nearly 1/4 of the book.
I recommend this book to anybody with even a passing interest in the subject.

Looks at the past, current and future debate on nonlocality in physics. Well written, this is more of a philosophical look at what reality could be then actual provable science. Nonetheless it is enjoyable and thought provoking. Worth reading if you are interested.

I love this guy! ! ! !
Does a fantastic job of explaining nonlocality [ya know, quantum entaglement, how a particle with either one type of spin or charge - - at the other end of the Universe - - flips to balance a particle which is altered - - at the opposite end of the Universe - - some call it Magic, some call it Weird, some call it Magically Weird!].
Remember, think local, Imagine Nonlocal! [The one point I wish to make - - which detracts nothing from this book - - is that I believe that Bell's Theorem, or his experiment postulated - - proved superentanglement, not fundamental quantum entaglement, something it took me many years to grasp. Yup, it's that . . . May the Force Be With You . . . thing again. . .]
Of course, if super entanglement exists, does causality actually exist? ? ?
