"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."

"As the writer, you're always a presence in the song. If you get close to what human beings are like, you're writing about common experience. We all do much the same things, so if you nail somebody, then you've also nailed yourself."
"I'm in the mood for another Moonstruck experience, for another romantic comedy."
"You learn from a conglomeration of the incredible past - whatever experience gotten in any way whatsoever."
"Existence itself does not feel horrible; it feels like an ecstasy, rather, which we have only to be still to experience."
"Not everything has a name. Some things lead us into a realm beyond words."
"It [discovering Finnish] was like discovering a wine-cellar filled with bottles of amazing wine of a kind and flavour never tasted before. It quite intoxicated me."
"She picked up the stout and took a sip. It slid down her throat like silk."
"Not everyone can experience what other people can... That's why movies come out... films and books... and short stories and novels..."
"Our experiences are the building blocks of the future hewn out of the granite of the present."
"Experience gives the greatest lessons of life."

"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."
"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."
"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."
"Spreading out the particle into a string is a step in the direction of making everything we're familiar with fuzzy. You enter a completely new world where things aren't at all what you're used to."
"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."
"Having those extra dimensions and therefore many ways the string can vibrate in many different directions turns out to be the key to being able to describe all the particles that we see."
"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."
