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

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

The thing I loved, particularly, was the mystery of science and the idea that science doesn't know all the answers, but it is a process of finding out. It's not like science will give you the right answer and science knows everything. I love the mysteries of it.

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

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

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.
