For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

Every scientific truth goes through three states: first, people say it conflicts with the Bible; next, they say it has been discovered before; lastly, they say they always believed it.

I really enjoyed working with Mariah, Alfre Woodward's character, because she's a wonderful actor, and I felt we had a natural chemistry that was reflective of real family members.

A century ago, scientists believed there was only one obvious stomping ground for alien biology in our solar system: Mars. Because it was reminiscent of Earth, Mars was assumed to be chock-a-block with animate beings, and its putative inhabitants got a lot of column inches and screen time.

Anyone who knows anything about me should know by now I am certainly not exactly a good politician. I am also willing to admit to you now that I never went to any classes that had anything to do political science.
