What is light? How has it shaped our understanding of the universe, our biology, and even our culture? In this illuminating episode Brian Cox and Robin Ince shine a spotlight on the fascinating science and history of light. From sun and circadian rhythms to the dazzling complexity of quantum, they explore how humans have understood and been influenced by light across time. Joining them to shed light on the subject are physicist Dr Jess Wade, Neuroscientist Professor Russell Foster and comedian Bridget Christie. Together, they trace the story of light from early scientific theories to the cutting-edge research of today. Expect tales of light emitting eyes, the mystery of wave-particle duality and why Bridget thinks that if we had understood light better, we’d never have believed in ghosts!
