The Science of Avatar is a book by Stephen Baxter, the pre-eminent SF writer of his generation, which examines James Cameron's epic Avatar movie. From journeys into deep space to anti-gravity unobtanium, from Pandora's extraordinary flora and fauna to transferring consciousness, the author reveals that we are closer to the world of Avatar than we know. Stephen Baxter is the master of what-if? science fiction. The book provides a glimmer of hope to those poor film-fans bemoaning their return to the earth after time spent on Pandora.
