You cannot think when you're ecstatic.

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.

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.

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 incessantly look for water in wells dug by men, and I have drunk enough sand to prove it.

Democracy is a brawl settled in advance by counting heads.

So multiverse or not, we still have to come to terms with the origin of the laws of nature. And the only viable explanation here is the divine Mind.

I like to co-author books to learn from those I write with.

When you look at our trade deals that are so bad. Our debt has doubled in seven and a half years to almost $20 trillion, under [Barack] Obama.

As crowds increase we build our forts of inattention, and the more we talk the easier it is to mean little and listen not at all.

I wanna be the ambassador to Chimichanga Flavor Town.

Even though I'm a pop singer, I really have more the life of a country singer.

I always think that I’m still this 13-year old boy that doesn’t really know how to be an adult, pretending to live my life, taking notes for when I’ll really have to do it.
