I'm a mathematician and always have been, as far as I can remember. I don't remember when I first got involved with mathematics, but I think of myself always as a mathematician first.
A mathematician, like a painter or a poet, is a maker of patterns. If his patterns are more permanent than theirs, it is because they are made with ideas.
My interests started about in science and in mathematics; I always thought I was going to be a mathematician.
And when I go around and talk to schools, what I tell the kids are, first of all, you have to accept each other's differences. Some of you are going to be a crappy football player, some of you are going to be a great mathematician. Whatever it is, accept each other's differences and help prop each other up.
I wrote about Alan Turing, the great mathematician and code-breaker. He was an absolutely different person, certainly more brilliant than I ever will be.
In some ways I'm a frustrated scientist or mathematician. The amount of times I've thought I'd go back to university and do theoretical physics because I like the big questions, but really I know now that that's not quite me. What's me is to do it in novels.
In 2010, my two Harvard mathematician colleagues and I dismantled kin-selection theory, which was the reigning theory of the origin of altruism at the time.
