Science has told us too much about the moon that it is fairly easy to imagine what it would be like to get there. It is certainly not a friendly place. Since there is no air or water, there can be no life of any kind. There is not much variety of scenery either. For mile after mile there are only flat plains of dust with mountains around them. Above, the sun and stars shine in the black sky. If you step out of the mountain shadow, it means moving from the severe cold into intense (强烈的) heat. These extreme temperatures continually break rocks away from the surface of the mountains. The moon is also a very silent world, for sound waves can only travel through air. But beyond the broken horizon, you see a friendly sight. Our earth is shining more brightly than the stars. From this distance, it looks like an immense (巨大的) blue, green and brown ball.

  A rising moon seems larger because it appears farther away. Why does the moon seem so much larger when it's on the horizon than when it's overhead? The question has perplexed us for millennia(千年).

  Known as the “moon illusion,” the effect has produced some studies that show when the moon hangs low in the sky it appears twice as big as when it reaches its zenith (顶峰). Yet the moon remains constant, both in size and distance from the earth.

  Lloyd Kaufman, professor of psychology and neural science at New York University, has pondered the problem for more than 40 years, and he thought he knew the answer but couldn't prove it. “It became increasingly clear that there was no way we were going to convince the critics without date,” he said.

  So he teamed up with his son, James Kaufman, a physicist at IBM's Almaden Research Center in San Jose, Calif. Both thought that the illusion was caused by our perception(感觉) of how far away we thought the moon was-its apparent distance. “I asked, can't we just measure the perceived distance that the brain uses in calculating the size of the moon?” the younger Kaufman says. “An experiment was the logical thing to do.”

  Aided by a few wizards at IBM, he came up with just the tool, a computerized moon simulator that allows the scientists to determine what people think they're seeing when they look at the moon. The result is surprising, and like any good illusion, the answer itself is a bit baffling(困惑). We think the horizon moon is bigger, the study shows, because we think it's farther away. That seems to defy commonsense. When the moon rises over the snowcapped mountain outside my office window in Alaske, it looks close enough to be just the other side of the mountain. But the study shows that isn't what my brain perceives. But don't let the science take the romance out of moonlit walks.

A programmer and an engineer are sitting next to each other on a long flight from Los Angeles to New York. The programmer leans over to the engineer and asks if he would like to play a fun game. The engineer just wants to take a nap, so he politely declines and rolls over to the window to catch a few winks.
The programmer persists and explains that the game is really easy and has a lot of fun. He explains, “I ask you a question, and if you don’t know the answer, you pay me $5. Then you ask me a question, and if I don’t know the answer, I’ll pay you $5.” Again, the engineer politely refuses and tries to get to sleep.
The programmer, now somewhat agitated, says, “OK, if you don’t know the answer you pay me $5, and if I don’t know the answer, I’ll pay you $50!” This catches the engineer’s attention, and he sees no end to this torment(折磨) unless he plays, so he agrees to the game.
The programmer asks the first question. “What’s the distance from the earth to the moon?” The engineer doesn’t say a word, but reaches into his wallet, pulls out a five dollar bill and hands it to the programmer. Now, it’s the engineer’s turn. He asks the programmer, “What goes up a hill with three legs, and comes down on four?” The programmer looks up at him with a puzzled look. He takes out his laptop computer and searches all of his references. After about an hour, he wakes the engineer and hands him $50. The engineer politely takes the $50 and turns away to try to get back to sleep. The programmer, more than a little miffed, shakes the engineer and asks, “Well, so what’s the answer?” Without a word, the engineer reaches into his wallet, hands the programmer $5, and turns away and goes back to sleep.
