David Spiegelhalter, Winton Professor of the Public Understanding of Risk at Cambridge University, has an OBE and is a Fellow of the Royal Society. His most recent, and possibly most cherished laurel, however, is the LOOP world title. Spiegelhalter skilfully defeated Burr in the grand final to gasps and cheers from the audience. Here he is with the world championship trophy, the Golden Cone. Picture: Alex Bellos.
