Wherever you are on Earth, there is more life present than in the rest of the known universe.

The main battle is to make people realise that doubt is important. Doubt is good. The 'don't know' answer sometimes is the box you should tick, and it's about not being scared about that fact. Even the greatest minds don't know everything.

I have a problem with telling jokes about physics. Quite often the audience have no idea what you are talking about and, to be honest, I don't know what I'm talking about either.

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.

Science, engineering, and technology discovers and invents new ways of doing things - but it doesn't dictate how we should do them.

My own ideas on the mechanism of catalytic phenomena were very different from those at one time commonly held, ideas which I no doubt owed to the influence of the illustrious teacher who had guided my first steps in chemistry nearly twenty years before - I refer, of course, to Berthelot.

I find that working with friends is always the goal, even if it's just one person. Because the comedy community is kind of insular, it's easy to run into people you've worked with, even if you worked with someone on something for a day, or whatever.
