“The master was an old Turtle--we used to call him Tortoise--'Why did you call him Tortoise, if he wasn't one?' Alice asked.We called him Tortoise because he taught us,' said the Mock Turtle angrily; 'really you are very dull!'You ought to be ashamed of yourself for asking such a simple question,' added the Gryphon; and then they both sat silent and looked at poor Alice, who felt ready to sink into the earth.”

“And how many hours a day did you do lessons?' said Alice, in a hurry to change the subject.Ten hours the first day,' said the Mock Turtle: 'nine the next, and so on.'What a curious plan!' exclaimed Alice.That's the reason they're called lessons,' the Gryphon remarked: 'because they lessen from day to day.”

“A well-known scientist (some say it was Bertrand Russell) once gave a public lecture on astronomy. He described how the earth orbits around the sun and how the sun, in turn, orbits around the center of a vast collection of stars called our galaxy. At teh end of the lecture, a little old lady at the back of the room got up and said: "What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise." The scientist gave a superior smile before replying, "What is the tortoise standing on?" "You're very clever, young man, very clever, " said the old lady. "But it turtles all the way down!”

“So Zeno is most famous for his tortoise paradox. Let us imagine that you are in a race with a tortoise. The tortoise has a ten-yard head start. In the time it takes you to run that ten yards, the tortoise has moved one yard. And then in the time it takes you to make up that distance, the tortoise goes a bit farther, and so on forever. You are faster than the tortoise but you can never catch him; you can only decrease his lead.”

“Sept.17 (1780). When we call loudly thro' the speaking-trumpet to Timothy ( the tortoise), he does not seem to regard the noise. Sept.18. Timothy eats heartily. Oct.3. No ring-ouzels seen this autumn yet. Timothy very dull.”

“Anyway.I’m not allowed to watch TV, although I am allowed to rent documentaries that are approved for me, and I can read anything I want. My favorite book is A Brief History of Time, even though I haven’t actually finished it, because the math is incredibly hard and Mom isn’t good at helping me. One of my favorite parts is the beginning of the first chapter, where Stephen Hawking tells about a famous scientist who was giving a lecture about how the earth orbits the sun, and the sun orbits the solar system, and whatever. Then a woman in the back of the room raised her hand and said, “What you have told us is rubbish. The world is really a flat plate supported on the back of a giant tortoise.” So the scientist asked her what the tortoise was standing on. And she said, “But it’s turtles all the way down!”I love that story, because it shows how ignorant people can be. And also because I love tortoises.”
