"I wouldn't have thought that a wrong theory should lead us to understand better the ordinary quantum field theories or to have new insights about the quantum states of black holes."

"I was very disappointed that Denzel didn't win Best Actor for The Hurricane because I thought he deserved it."
"Oh, gentlemen, perhaps I really regard myself as an intelligent man only because throughout my entire life I've never been able to start or finish anything. Granted, granted I'm a babbler, a harmless, irksome babbler, as we all are. But what's to be done if the sole and express purpose of every intelligent man is babble--that is, a deliberate pouring from empty into void."
"Far more thought and care go into the composition of any prominent ad in a newspaper or magazine than go into the writing of their features and editorials."
"All thought must, directly or indirectly, by way of certain characters, relate ultimately to intuitions, and therefore, with us, to sensibility, because in no other way can an object be given to us."
"And I think all Nazis didn't see themselves as bad people. I've never met a racist yet who thought he was a racist. Or an anti-Semite who thought they were anti-Semitic."

"You have that one basic string, but it can vibrate in many ways. But we're trying to get a lot of particles because experimental physicists have discovered a lot of particles."
"Technically you need the extra dimensions. At first people didn't like them too much, but they've got a big benefit, which is that the ability of string theory to describe all the elementary particles and their forces along with gravity depends on using the extra dimensions."
"If I take the theory as we have it now, literally, I would conclude that extra dimensions really exist. They're part of nature. We don't really know how big they are yet, but we hope to explore that in various ways."
"Even before string theory, especially as physics developed in the 20th century, it turned out that the equations that really work in describing nature with the most generality and the greatest simplicity are very elegant and subtle."
"Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle."
"One of the basic things about a string is that it can vibrate in many different shapes or forms, which gives music its beauty."
"As for the forces, electromagnetism and gravity we experience in everyday life. But the weak and strong forces are beyond our ordinary experience. So in physics, lots of the basic building blocks take 20th- or perhaps 21st-century equipment to explore."
"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."
"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."
"The theory has to be interpreted that extra dimensions beyond the ordinary four dimensions the three spatial dimensions plus time are sufficiently small that they haven't been observed yet."
