I love learning about the science that governs the universe around us and want to share the delight of discovering how things work and why.

Some of the first infographics I did started off as notes to myself: trying to plot out, for instance, how IP addresses are allocated. After a while, I thought, 'This is a neat thing I can share with people, and they can follow me along in that process of understanding.'

People often say, 'I like your comics, even though I don't know enough math to get all of them,' as if it's some kind of club where they don't belong. But there's no club. There's just lots of people who are excited about thinking, learning, joking, and sometimes overanalyzing things.

A lot of times, the idea of a comic will be, 'Wouldn't it be cool if you...' But instead of doing it, I'll draw a comic about it.

Being able to make a comedy at Disney was really appealing.

I was depressed as a child. I found it hard to make friends. My favourite thing was locking myself in the bathroom and practising comedy routines.

Some comics are in it for what they can get out of it. Others are in it for a love of comedy. I think those that are in it for a genuine love of comedy find each other within the circuit and become friends.

I'm not opposed to doing science fiction or comedy, but there has to be respect. I refuse to be the joke, the fat woman joke, in any movie. I've turned down roles.
