I always looked at myself as a physicist learning new tricks by looking at nature.

Space, the whole universe - I know no better place to find new physics.

Whenever you have a good idea, it's inevitable some people will criticize it and deny it. Some people will try to prove it's wrong.

The solar probe is going to a region of space that has never been explored before. It's very exciting that we'll finally get a look. One would like to have some more detailed measurements of what's going on in the solar wind. I'm sure that there will be some surprises. There always are.

I'm proud of the fact that I thought of the solar wind. It was an exercise in pursuing curiosity, which is the main motivation for studying physics from a personal standpoint.

One simply runs out of energy as you get old. One doesn't take on new tasks of exploration because it takes an extended period of intense thinking and working on it, and that becomes impractical.

The tail of the comet always points straight away from the sun, in antisolar direction. Sometimes the tail trails behind, but sometimes it's perpendicular, and sometimes it's ahead of the comet like a headlight on a railroad locomotive.

I was always fascinated by how things work and learning about them.

The sun is the primary puzzle in the universe.

These are decent people. We're in a situation with Cedric that's tough because of a lot of factors. I think the expectation was that this one would go smoother than the facts have allowed it to go. But we've maintained a professional approach and respect, and that's been important.
