For me, the most fascinating interface is Twitter. I have odd cosmic thoughts every day and I realized I could hold them to myself or share them with people who might be interested.

I try to educate the public and let them make the decisions for themselves.

There's a saying in the scientific community, that every great truth goes through three phases. First, people deny it. Second, they say that it conflicts with the Bible. Third, they say that they've known it all along.

Whether or not you can never become great at something, you can always become better at it. Don't ever forget that! And don’t say “I’ll never be good”. You can become better! and one day you’ll wake up and you’ll find out how good you actually became.

One of the things that fascinates me most is when people are so charmed by the universe that it becomes part of their artistic output.

Chimpanzees are an evolutionary hair's-width from us.... Now imagine a species on Earth, or anywhere else, as smart compared with humans as humans are compared with chimpanzees. How much of the universe might they figure out?

If a scientist is not befuddled by what they're looking at, then they're not a research scientist.
