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

I've always been a bit of a dreamer. I've always loved to look and seek, and explore and find out.

I'd missed science and what it was all about because I was too busy trying to think of other things, when I was at school. I was too busy trying to be James Dean.

I wasn't naturally a scientist, but I was always fascinated by how the world worked and why things were the way they were.

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.

There is so much wonder and joy in science, about understanding how the world works and why the world is the way it is. It's not just for academics. It is a thing that's available to everyone.
