James Gleick, whose latest book is Time Travel, is interviewed by Richard Wolinsky.

The author of The Information, an all-encompassing exploration about how we give and receive information, returns with Time Travel, which focuses on the history of time travel in literature and physics, and on the various paradoxes and possibilities of the idea of time travel. In this interview, he talks about H.G. Wells and his time machine, about Robert Heinlein and the role of science fiction in talking about time, and of course on the physics of time, infinite realities and how and why we focus so clearly on the concept.
