Gifted physicist Richard Feynman (1918-88) was known as the 'great explainer' due to his ability to help non-scientists 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.
