But this is exactly what happened to Marcus du Sautoy at the Science Museum — and by means of a mathematical argument at that. Only du Sautoy wasn't being himself of course. He was playing the role of X in the new play, X&Y.

In February this year we were lucky enough to interview Freeman Dyson at the Institute for Advanced Studies in Princeton, USA. Dyson is now 89 and still does physics every day in his first floor office at the Institute. Here is an edited version of our interview that we hope conveys his generous nature, wit and intellect.
