I have a tendency, more than most other physicists, to try to figure out everything all at once, before I publish. And even to try to figure out everything in my head, without pencil and paper.

There was a long history of speculation that in quantum gravity, unlike Einstein's classical theory, it might be possible for the topology of spacetime to change.

There is a difference between knowing what is true and knowing why it is true

We know a lot of things, but what we don't know is a lot more.

Im actually, for the most part, a complete agnostic politically.

So when you ask me how string theory might be tested, I can tell you what's likely to happen at accelerators or some parts of the theory that are likely to be tested.

I have a much easier time imagining how we would understand the big bang, even though we can't do it yet, than I can imagine understanding consciousness.

As of now, string theorists have no explanation of why there are three large dimensions as well as time, and the other dimensions are microscopic. Proposals about that have been all over the map.

One very important aspect of string theory is definitely testable. That was the prediction of supersymmetry, which emerged from string theory in the early '70s.

String theory is an attempt at a deeper description of nature by thinking of an elementary particle not as a little point but as a little loop of vibrating string.

M stands for Magic, Mystery, or Matrixaccording to taste

Work like hell, tell everyone everything you know, close a deal with a handshake, and have fun.

A friend loves at all times.

The problem with gender is that it prescribes how we ´should' be rather than recognizing how we are.

To eat the forbidden is to disobey the law of God

I'm a synthesist. I'm always making music. And I make a lot of different kinds of music all the time. Some of it gets finished and some of it doesn't.

It's like you're organically developing yourself, moving out, metamorphosing into other forms depending on where you are, what you're doing at the time, how you want to play on things.

I am more than ever convinced that what we eat today is what we are tomorrow.

What's the worst that could happen? Everyone turned me down; big deal.

There may be honor among thieves, but there's none in politicians.

Is the mean temperature of the ground in any way influenced by the presence of heat-absorbing gases in the atmosphere?
