I enjoy reading blogs, but am not interested in having my spurious thoughts out there.

According to inflation, the more than 100 billion galaxies, sparkling throughout space like heavenly diamonds, are nothing but quantum mechanics writ large across the sky. To me, this realization is one of the greatest wonders of the modern scientific age.

Writing for the stage is different from writing for a book. You want to write in a way that an actor has material to work with, writing in the first person not the third person, and pulling out the dramatic elements in a bigger way for a stage presentation.

Oftentimes, if you're talking to a seasoned interviewer who asks you a question, they may do a follow-up if they didn't quite get it. It's rare that they'll do a third or fourth or fifth or sixth follow-up, because there's an implicit, agreed-upon decorum that they move on. Kids don't necessarily move on if they don't get it.

The number of e-mails and letters that I get from choreographers, from sculptors, from composers who are being inspired by science is huge.

I've seen children's eyes light up when I tell them about black holes and the Big Bang.

When you know the answer you want, it is often all too easy to figure out a way of getting it.
