In the history of physics, every time we've looked beyond the scales and energies we were familiar with, we've found things that we wouldn't have thought were there. You look inside the atom, and eventually you discover quarks. Who would have thought that?
You learn that the interest is in what you don't yet know and that theories evolve. But we nonetheless have progress and improved knowledge over time.
We live in a world where there are many risks, and it's high time we start taking seriously which ones we should be worried about.
There can sometimes be this fear among laypeople: 'I don't understand everything in science perfectly, so I just can't say anything about it.' I think it's good to know that we scientists are also confused some of the time.
If you are a responsible scientist, you are going to present your new results in a paper, and maybe if, over time, things are established, and it's prime time for the public to hear about it, then you include it in a book.
I can be a good listener. I can ask the right questions a lot of the time.
