I always found it satisfying that gravity was described by Einstein's geometric theory of general relativity.

I think the universe is pure geometry - basically, a beautiful shape twisting around and dancing over space-time.

The mathematics of quantum mechanics very accurately describes how our universe works. And it tells us our reality is continually branching into different possibilities, just like a coral.

You cannot think when you're ecstatic.

Everything that can happen, does. That's quantum mechanics. But this does not mean everything happens. The rest of physics is about describing what can happen and what can't.

There are a lot of good things about string theory, and it's great that some people want to work on it.

Yeah, I am a guy working on physics outside of academia. But I'm nowhere near Einstein's caliber.

Math does come easily to me, but I was always much more interested in what theorems imply about the world than in proving them.

Science is our last and greatest frontier.

Ninety-five per cent of my time is virtually wasted.

Coral is a very beautiful and unusual animal. Each coral head consists of thousand of individual polyps. These polyps are continually budding and branching into genetically identical neighbors.

Science blasphemed when tries to eliminate scarcity in economy.

Drug addicts are so funny that way. Just spinning around, lost in their own little world. Doing so much, accomplishing so little. How sad.

After a certain point, money is meaningless. It ceases to be the goal. The game is what counts.

Perhaps the greatest lesson [Huxley] learned from reading Carlyle was that real religion, that emotive feeling for Truth and Beauty, could flourish in the absence of an idolatrous theology.

I did this movie with Spike Lee called Sucker Free City, and that would have to be my favorite role by far. It was just so much fun to work with Spike and shoot in San Francisco.

A trusty comrade is always of use; and a chronicler still more so.

I think many of my students have followed the advice I gave years ago, to give more than you take.

The hands are the instruments of man’s intelligence.

I have a career, I worked so hard for it.

Here, on the river's verge, I could be busy for months without changing my place, simply leaning a little more to right or left.
