Brian Cox and Robin Ince raid the archives of the Royal Society to reveal an unexpected history of science with guests Rufus Hound, Tori Herridge, Matthew Cobb and Keith Moore. Together they explore some of the surprising and wackiest scientific endeavours undertaken by early members of the Royal Society from the discovery of sperm to testing the insect repelling properties of unicorn horn. They hear how a beautiful book on fish almost scuppered Newton's Principia Mathematica and why a guide to the fauna of Switzerland ended up including depictions of dragons.
