George Porter gave the 1976 Christmas Lectures "The Natural History Of A Sunbeam" about the power of light, from the role it plays in stimulating life to supplying energy to our homes.

The first lecture "First Light", where this clip is from, sees George explaining how colour is created through light scattering which John Tyndall discovered.
