Why you should listen

Stephen Hawking is perhaps the world's most famous living physicist. A specialist in cosmology and quantum gravity and a devotee of black holes, his work has probed the origins of the cosmos, the nature of time and the universe's ultimate fate -- earning him accolades including induction into the Order of the British Empire. To the public, he's best known as an author of bestsellers such as The Universe in a Nutshell and A Brief History of Time, which have brought an appreciation of theoretical physics to millions.

Though the motor neuron disorder ALS has confined Hawking to a wheelchair, it hasn't stopped him from lecturing widely, making appearances on television shows such as Star Trek: The Next Generation and The Simpsons -- and planning a trip into orbit with Richard Branson's Virgin Galactic. (He recently experienced weightlessness aboard Zero Gravity Corporation's "Vomit Comet.") A true academic celebrity, he uses his public appearances to raise awareness about potential global disasters -- such as global warming -- and to speak out for the future of humanity: "Getting a portion of the human race permanently off the planet is imperative for our future as a species," he says.

Hawking serves as Lucasian Professor of Mathematics at the University of Cambridge, where he continues to contribute to both high-level physics and the popular understanding of our universe.

“We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.” — Stephen Hawking
