I'm glad the universe is pointless. It means if I get to the end of my life, the universe can't turn to me and go, 'What have you been doing, you idiot? That's not the point!

Science is very cross-generational; you're not just aiming it at twentysomethings, or eightysomethings. Every town's got a really broad selection of people and age groups interested in science.

Once you start looking at the world rationally, it becomes much more exciting.

I don't have any hobbies because my working job is my hobby. What I do is I spend my whole time looking through telescopes and having brain scans and buying books about various different ideas and I just sit around, that's my life.

I want to create shows which are interesting. I hope that some people are excited by some of the ideas.

There can be a science to joke writing, there are certainly rules and patterns that can be followed, but I think most of the best comedy goes beyond the rules.

We as human beings like to be cocksure and certain.
