Rich Cochrane is a writer and educator. He devises and teaches innovative maths courses for artists at Central Saint Martins, London, and lectures in maths and philosophy at City Lit. He has been commissioned by, among others, the Museum of London to bring cultural history - including maths - to a wider audience. Rich has written books on literature, music and computing and has for many years organized public educational events in public houses and cafes in London. He also spent a decade working in the City, writing software for derivatives trading floors, which is how he discovered that maths was a lot more interesting than it seemed to be at school, and he has degrees in both maths and English literature and a PhD in philosophy.
