Tim Harford speaks to Persi Diaconis, top professor of maths and statistics and legendary magician. The Stanford University professor and co-author of the book Magical Mathematics has an enthralling story to tell of how he discovered magic as a boy - and as a consequence, a love of maths. And to illustrate how closely maths and magic are linked, Crossing Continents editor and the 91福利社's in-house magician, Hugh Levinson, performs a mathemagical card trick.
