"Sex in ten dimensions is impossible... topologically."

“My physics has been extremely mainstream, ... It's not true that I'm some sort of a , not at all.”

“The problem with general relativity is that the principles are pretty simple and the computations are always ugly.”

“Elegance requires that the number of defining equations be small. Five is better than ten, and one is better than five. On this score, one might facetiously say that String Theory is the ultimate epitome of elegance. With all the years that String Theory has been studied, no one has found even a single defining equation! The number at present count is zero. We know neither what the fundamental equations of the theory are nor even if it has any.”

“The standard SU×SU×U theory of strong, electromagnetic, and weak interactions appears to correctly describe physics down to the smallest distance scales yet probed.”
