Q: We've talked about snails   and their slow move. But much of the time snails don't move at all. They're in their shells ---sleeping . Hot sun will dry out a snail's body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep. In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can't see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail's little mouth goes to work. A snail's mouth is no longer than the point of a pin . Yet it has 256,000 teeth! The teeth are so small that you can't see them. But they do their work.. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones. Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.

Q: I don't have too many memories of my father because he was so sick in the last years of his life. But there aresome that I am often reminded of and which may have developed my love ofscience. When I was small, I was somewhatafraid of lightning and thunder . My father explained it. The explanation wasin words that a child could understand but was basically correct. I gained a betterunderstanding and learnt something from him. What he said was that there was electricity in the cloudsand it traveled to the ground like a spark . When it traveled through the air, it made the air so hot that it burned. Then there was nothing where the air had been and the air all around rushed in to fill the space. Saying this, he clapped his hands together very loudly, pretending to be the air rushing in, and said that makes the thunder. When I hear thunder, I can still hear that clap clearly. He also explained why a cloudy winter night was warmer than a clear one. When there were clouds, they were like blankets  which kept the earth and us warm. He said that if there were no clouds, we had no blankets and were _ to the universe. Our warmth was going toheat the whole universe. Even today, I still feel on the edge of space on a very clear night. I am sure there were many other lessons that Itook but no longer remember most of them now. What I didlearn, in general, was that there were explanations and that the more I understood them, the more comfortable the world was to live in.
