We can summarize electricity, magnetism and gravity into equations one inch long, and that's the power of field theory. And so I said to myself: I will create a field theory of strings. And when I did it one day, it was incredible, realizing that on a sheet of paper I can write down an equation which summarized almost all physical knowledge.

What do oil company executives, vampires and NASA bureaucrats all have in common? They fear solar energy.

We are not at the end but at the beginning of a new physics. But whatever we find, there will always be new horizons continually awaiting us.

Faust was this mythical figure who sold his soul to the devil for unlimited power. The Japanese have made that Faustian bargain because they don't have coal, oil or hydro power.

My point is, no one can stop the Internet. No one can stop that march. It doesn't mean that it's going to be smooth, though.

Combining quantum entanglement with wormholes yields mind boggling results about black holes. But I don't trust them until we have a theory of everything which can combine quantum effects with general relativity. i.e. we need to have a full blown string theory resolve this sticky question.

When you come up with a theory, you fall in love with the beauty the simplicity and elegance of it. But then you have to get a sheet of paper and pencil and crack out all the details. Hundreds and hundreds of pages. Because you have to prove it.
