Did aliens help prehistoric Britons found the ancient Woolworths civilisation? And what does tying your shoe laces have to do with DNA? Find out with this year's popular lectures organised by the London Mathematical Society. Matt Parker of Queen Mary, University of London, will explore how seemingly incredible results can actually be meaningless random patterns, and Dorothy Buck of Imperial College, London, will look at how mathematical knot theory helps to understand DNA.
