Mathematics is a place where you can do things which you can't do in the real world.

I think science is a foreign land for many people, so I think of my role as an ambassador's job.

I'm obviously attuned to pick up mathematics whenever I can see it. But in Mozart there is a lot of conscious use of mathematical symbolism and numbers in order to try and give messages.

Its my belief that you can take everyone down a logical path if you take them slowly enough, and the trouble is that mathematical brains can get scrambled a little bit on the way. You get a bad teacher, it messes you up for the rest of the journey.

I think my primary audience is in some sense an adult audience, because I think that will then have a knock-on effect for children.

The stage is like a laboratory where you can run theatrical experiments, imposing interesting conditions on the cast or story and seeing how they pan out. Each new play is like creating a tiny virtual universe enclosed by the confines of the stage.

Theory is needed to tell you where to look.
