Light Fantastic: Light, the Universe and Everything (4 of 4)

Simon Schaffer investigates just how puzzling studying light turned out to be and how it affected knowledge of science, art and the human mind. He looks at how the industrial revolution was the catalyst for new scientific investigations into colour, how Cambridge anthropological expeditions to the Torres Straits in the late 19th century revealed strange truths about human perception and how Einstein's revelations about light, the universe and everything would completely change our worldview.
