My experience has been in a short 77 years that in the end when you fight for a desperate cause and have good reasons to fight, you usually win.

Life improves slowly and goes wrong fast, and only catastrophe is clearly visible.

The science of today is the technology of tomorrow.

Secrecy, once accepted, becomes an addiction.

It was only in the second year of my Ph.D. that I started acting. I wasn't in school plays or anything; I was in bands, but I wasn't cool. There's no such thing as a cool physics person, is there?

When you're looking that far out, you're giving people their place in the universe, it touches people. Science is often visual, so it doesn't need translation. It's like poetry, it touches you.

In string theory, all particles are vibrations on a tiny rubber band; physics is the harmonies on the string; chemistry is the melodies we play on vibrating strings; the universe is a symphony of strings, and the 'Mind of God' is cosmic music resonating in 11-dimensional hyperspace.

When I first went to college, I went into physics, and my goal was to help perfect nuclear fusion so I could solve the energy crisis and global warming. I probably would have done it, too, if I'd stuck to it.
