I was awful at science at school, as a subject, because I didn't have the discipline. But, I was awful at music, as well, and I loved music.

At the heart of science is experimentation. Science doesn't care what you think. What's important is experimenting and actually working stuff out.

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.

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.

You don't have to be musician to listen to music, and you don't have to be a filmmaker to go to the cinema, but somehow when we think of science, we think of it only as an academic discipline.

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.

In my lifetime, the population of the world has doubled.
