We as human beings like to be cocksure and certain.

To be paid, to be employed to be an enthusiast and be excited about existence is fantastic.

One idea I explore in my stand-up show is whether, if you try looking at the universe rationally and avoid coping mechanisms like mysticism or religion, you can still be happy knowing you are going to die after a brief time on this spinning ball.

The worst, the most difficult thing I think is that the more you become intrigued by science and the information is out there, the more you are aware of the paucity of your own knowledge.

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

Homeopaths do not have a physical brain, but merely 'skull water' with the memory of brains.

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.
