3-minute Stephen Hawking

Stephen Hawking is the most brilliant theoretical physicist since Einstein. He is possibly the greatest living scientific genius but also a highly successful author who has revealed the most tricky of topics to ordinary minds, and a vocal campaigner of social and political issues, including the rights of disabled people. 3-Minute Stephen Hawking is the instant introduction to this exceptional genius. His intellect and enthusiasm undimmed by the motor neurone disease that hampers his body, his work on gravitational singularities (black holes), the nature of time, and the attempt to reconcile quantum mechanics with Einstein's general relativity is genuinely brain-bending.
