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

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

If you can make yourself symmetrical, you're sending out a sign that you've got good genes, you've got a good upbringing and therefore you'll make a good mate.

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.

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.

You know, I'm not terribly fast at my times tables, because that's not what I think mathematics is about.

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

Mathematics has beauty and romance. It's not a boring place to be, the mathematical world. It's an extraordinary place it's worth spending time there.

Primes are the atoms of the arithmetic - the hydrogen and oxygen of the world of numbers

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.

Theory is needed to tell you where to look.

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.
