A quite interesting (and readable) treatise on time travel. The author is witty and while my eyes did glaze over a few times, it was an easy read. He refers to many instances of the subject in popular culture (and goes back to Aristotle to support some theories about it -- and, of course, Einstein). The book includes a long list of suggested reading (fiction and non-) to peruse if you are into the whole concept (and why wouldn't you be if you're reading this?)
He does dwell on H.G. Wells, crediting him as probably the earliest proponent of the idea in popular literature, but also uses many other books, movies and TV shows to underscore a point. (He mentions a Dr. Who episode called "Blink" which I was glad to find online (at Amazon Prime, actually) and found it a cleverly written, amusing take on time travel.)
All in all, a fun book, but not what one would call "a beach read.)
An odd subject for a science writer. It's a history of thought about time travel, mostly in the realm of science fiction. He keeps coming back to H. G. Wells.
