Proof, Pizza and the Electric Guitar by David Acheson Why is proof so important? Does pizza have a place in serious mathematics? And what has all this got to do with the electric guitar? To find out, David takes an off-beat look at some of the most important ideas in mathematics, with live demonstrations and computer experiments. David's Biog David Acheson is a Fellow of Jesus College Oxford, and the author of the highly acclaimed book 1089 and All That. In 1992 he discovered a strange gravity-defying upside-down-pendulum theorem, a possible explanation of the classic Indian Rope Trick, which he demonstrated live on BBC’s Tomorrow’s World. In his spare time, David is a keen guitarist.
