Using physics to explain how the world works. Richard Feynman (1918-88) was one of the most remarkable and gifted theoretical physicists of any generation. He was also known as the 'Great Explainer' because of his passion for helping non-scientists to imagine something of the beauty and order of the universe as he saw it. In this series, Feynman looks at the mysterious forces that make ordinary things happen and, in doing so, answers questions about why rubber bands are stretchy, why tennis balls can't bounce for ever and what you're really seeing when you look in the mirror.
