Light Fantastic - Let There Be Light

Series in which Professor Simon Schaffer explores man's fascination with light begins by revealing the unwitting role religion played in forging our scientific understanding of the properties of light. He reveals the extraordinary lengths to which the early light pioneers went to unlock the mysteries of light. The Greek philosopher Empedocles marked his theory that light travels like laser beams from our eyes by throwing himself into the volcano Mount Etna. The Roman Church's obsession with Easter forced it to turn a blind eye to its own doctrines, as the religious authorities sanctioned the conversion of cathedrals into massive sun clocks, a move that would eventually drive the rabidly anti-Catholic Isaac Newton to unravel the true essence of light.
