In 1990 he joined the BBC’s Science Department, as a producer and director in programmes such as Tomorrow’s World and Horizon. In 1996 he directed Fermat’s Last Theorem, a BAFTA award winning documentary about the world’s most notorious mathematical problem. This was also the subject of his first book, Fermat’s Last Theorem. This was the first book about mathematics to become a No.1 bestseller in the UK. His book The Code Book resulted in a return to television when he presented The Science of Secrecy, a 5-part series for Channel 4. The stories in the series range from the cipher that sealed the fate of Mary Queen of Scots to the coded Zimmermann Telegram that changed the course of the First World War. Other programmes discuss how two great nineteenth century geniuses raced to decipher Egyptian hieroglyphs and how modern encryption can guarantee privacy on the Internet. Other books include Big Bang and Trick or Treatment?
