"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."

"Experience is not worth the getting. It's not a thing that happens pleasantly to a passive you--it's a wall that an active you runs up against."
"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."
"How long does the experience of pleasure or pain stay with you? For as long as there is weakness within. Then, further ahead they will not be there. There, one remains the 'Knower' of experience of pleasure and pain."
"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."
"Simultaneously the whole party moved toward the water, super-ready from the long, forced inaction, passing from the heat to the cool with the gourmandise of a tingling curry eaten with chilled white wine."
"Now that he wanted to feel like he was having a bad dream, he wasn't. He was having a bad reality, and that was something from which you could not wake."
"Mr Lorry asks the witness questions:Ever been kicked? Might have been.Frequently? No. Ever kicked down stairs? Decidedly not; once received a kick at the top of a staircase, and fell down stairs of his own accord."
"Elders in the dark see better than children in the light."
"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."

"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."
"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."
"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."
"Quantum mechanics brought an unexpected fuzziness into physics because of quantum uncertainty, the Heisenberg uncertainty principle."
"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."
"In Einstein's general relativity the structure of space can change but not its topology. Topology is the property of something that doesn't change when you bend it or stretch it as long as you don't break anything."
"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."
"On the other hand, we don't understand the theory too completely, and because of this fuzziness of spacetime, the very concept of spacetime and spacetime dimensions isn't precisely defined."
"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."
"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."
