Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets(彗星)which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems.

However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse(椭圆形).

Now Halley set to work. He figured out(解决，计算出)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart.

This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the ore his thought that there had been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again.

It was an astonishing idea! Halley felt certain though to make a prediction(预言)of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley’s prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley’s comet, in his honor.

5 Edmund Halley figured out the orbit of ____.

A. some different comets appearing several times

One day when Isaac Newton was reading a book under an apple tree on the farm, an apple fell down and hit him on the head. For most people that would be the end of the story, but not for Newton. Why did the apple fall out of the tree? Does everything fall? What makes things fall? Can anything stop things from falling? Are the sun, moon, and stars falling? Why don’t they ever hit the ground?

So many questions. Newton spent many years answering these questions by thinking and doing experiments. He made up the law of gravity. According to this law everything pulls everything else to itself by a force called gravity. How strong that force is depends on how heavy the things are and how close together.

Newton’s law of gravity not only explained how things fall on earth, but now planets move around the sun and how moons move around planets. A friend of his, Edmund Halley, decided to try Newton’s theory on comets. People had been studying comets for hundreds of years without figuring them out, so he decided to study their reports and compare them to Newton’s theory.

Up till then people had thought that comets just came and went, and that nobody could know when or why. But Newton’s law of gravity gave rules that Halley could use to study the records of comets. He found some reports of a big bright comet that he was sure was the same one, coming back every 75 years. He predicted when it would come back next.

If anybody still didn’t believe Newton, then the appearance of Halley’s Comet just when Halley had predicted it using Newton’s ideas was enough to convince them. Halley’s Comet has come a few times since then, always right on schedule. You’ll be able to see it on its next trip near the sun and earth when you’re old enough to be a grandparent.
