New series 1/4. A stimulating and beautifully filmed exploration of humanity's fascination with light, presented by Professor Simon Schaffer. Let There Be Light. Early pioneers resorted to extraordinary measures to unlock the mysteries of light. Greek philosopher Empedocles, for example, hurled himself into Mount Etna in a bid to support his theory that light travelled like laser beams from our eyes. But, as Schaffer reveals, it was left to Sir Isaac Newton to unravel its true essence.
