"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."

"A misadventure is an act that has a safer, less self-detrimental, less interesting alternative. But you choose that act because you want to do something memorable and worthy of discussion."
"Life is a book. Read it. But do not forget to write yours."
"At least I can say I once worked a day on a tea plantation in Far North Queensland."
"Beyond these moments, she could hardly count the fumbling ministrations of boys in high school who, even to her senior prom, never went beyond sticky pleasantries. With one exception, it was just a sort of half-clothed handshake for bragging rights, none hers."
"To use the same words is not a sufficient guarantee of understanding; one must use the same words for the same genus of inward experience; ultimately one must have one's experiences in common."
"We live that we might have experience; that through it we might gain wisdom, compassion, faith, and inner strength."
"Failure is only an experience. Experience is the foundation of any success."
"Today's experience is necessary to equip you fully for the future."
"Experience comes from failure and success comes from experience. Today's pain will bring tomorrow's gain."
"But human experience is usually paradoxical, that means incongruous with the phrases of current talk or even current philosophy."

"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."
"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."
"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."
"It's indeed surprising that replacing the elementary particle with a string leads to such a big change in things. I'm tempted to say that it has to do with the fuzziness it introduces."
"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."
"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."
"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."
"But the beauty of Einstein's equations, for example, is just as real to anyone who's experienced it as the beauty of music. We've learned in the 20th century that the equations that work have inner harmony."
