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.

My interest in biology was pretty much always on the philosophical side.

Especially girls, but any kids exposed to music programs and arts programs do much better on their tests. They have a better chance of going to college. They can focus better. You know, we're not just automatons learning how to work machines and do engineering and math and science. All of that's great, but you've got to build a whole person.

As we talk with candour, we open the doors to new possibilities and new areas of cooperation in advance in democracy, in combating terrorism, in energy and environment, science and technology and international peacekeeping.

What is the intersection between technology, art and science? Curiosity and wonder, because it drives us to explore, because we're surrounded by things we can't see.
