Theory is needed to tell you where to look.

But actually a code is a language for translating one thing into another. And mathematics is the language of science. My big thesis is that although the world looks messy and chaotic, if you translate it into the world of numbers and shapes, patterns emerge and you start to understand why things are the way they are.

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.

The power of mathematics is often to change one thing into another, to change geometry into language.

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.

The point is with good maths skills you have just wonderful opportunities and if you don't have good maths skills, there are just so many things that you won't be able to do.

The best mobile phone had the best mathematician. They know how to fit a huge amount of data into a small amount of space. How to do things efficiently, how to do them cleverly.
