What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.

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.

A man who offers to cook after he's seen you trying to freeze a dead dog has to be at least a little bit keen.

...when an old person dies, a whole library disappears.

I believe in sometimes getting mad and always getting even.

The first job of a writer is to be honest.

Well, what Cory Booker and John Lewis are right about is to talk about the racist past of Donald Trump.

Go out and walk. That is the glory of life.

Food is one of the great organizing tools.

I like the idea of exercising, but I never do.

Only some radical change can divert the downward course of my spirit, some startling new place or people to arrest the drift, the drag.

Our ideas must agree with realities, be such realities concrete or abstract, be they facts or be they principles, under penalty of endless inconsistency and frustration.
