If you go through life and actually get to find out the thing you want to do, you're very lucky.

Newton had a very good description of gravity, back in the day, and then Einstein came along and dug a little bit deeper. Science is like peeling an onion. You go deeper and deeper and deeper, and it doesn't stop. It's not like you will get to a right answer.

I've never felt scared of flight, ever. It's really weird. I don't know. They stick a gin and tonic in your hands and I just think, "Life is good!"

I was very much the laymen, trying to find stuff out because I'm curious about the world.

Those people who are scared of science or are a bit dismissive of science tend to not really understand what science really is, which is the most beautiful, most elegant and most creative way of looking at the world.

I've found the thing in life that I adore, which is working in science television. It's just a big adventure, really.

I love being in America. I love America. I absolutely adore working in America. I'm at my happiest when I'm in the States.
