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.

The Life at Conception Act legislatively declares what most Americans believe and what science has long known - that human life begins at the moment of conception and, therefore, is entitled to legal protection from that point forward.

But the scientific importance of a change in knowledge of fact consists precisely in j its having consequences for a system of theory.

I was afraid that science-fiction buffs and everybody would say things like, 'You know, there's no sound in outer space.'

When asked if I am pessimistic or optimistic about the future, my answer is always the same: If you look at the science about what is happening on Earth and aren't pessimistic, you don't understand the data.
