Since 2008, Big Think has been sharing big ideas from creative and curious minds. The Think Again podcast takes us out of our comfort zone, surprising our guests and Jason Gots, your host, with unexpected conversation starters from Big Think’s interview archives. 

James Gleick is one of our greatest living science writers,  author of The Information: A History, a Theory, a Flood. His first book, Chaos, was a National Book Award and Pulitzer Prize finalist and a national bestseller. His other books include the best-selling biographies, Genius: The Life and Science of Richard Feynman, and Isaac Newton, both shortlisted for the Pulitzer Prize. James’ new book Time Travel: a History, is an utterly fascinating journey through the history of an idea that has become part of the fabric of philosophy, science, and our daily lives, even though we can’t really do it yet. Not really.

In this episode, James and host Jason Gots talk about why we're so obsessed with something that's evidently impossible. 

Surprise conversation starter interview clips in this episode: Penn Jillette on "atheist prayers" and David Eagleman on our perception of time

James Gleick Quote: “There are scientists who are always in a state of doubt. Who consider that the normal thing is just not to know things. I’m thinking of Richard Feynman. And I believe that there are people in the realm of religion who have the same view of faith. They are talking about faith as a twin of doubt. That faith does not mean certainty––It means ‘I am trying to come to grips with my sense that what we see and touch in the universe is not all there is.’”
