Much of today’s science of physics is based on Newton’s discovery of the three laws of motion and his theory of gravity ( 地球引力). Newton said, “If I saw further than other men, it was because I stood on the shoulders of giants.” One was the great Italian scientist, Galileo. Another was the Polish scientist Nicholas Copernicus, who had begun a scientific revolution. It led to a completely new understanding of how the universe worked. Galileo continued and expanded the work of Copernicus. Newton built on the ideas of these two scientists and others. He found and proved the answers for which they searched.

Issac Newton was born in Woolsthorpe, England, on December 25th, 1642. He was born early and no one expected him to survive. He lived until he was 84. His father died before he was born. His mother married again. He lived with his grandma on the family farm.

As a boy, he liked to make things. He also decided to find a different way to measure the speed of the wind. On a windy day, he measured how far he could jump with the wind at his back. Then he measured how far he could jump with the wind in his face. From the difference between the two jumps, he made his own measure of the strength of the wind. Strangely, Newton became a much better student after a boy kicked him in the stomach. The boy was one of the best of the students  in the school. Newton decided to get even with him by getting higher marks than the boy kicking him. Newton became the top student at the school very soon.
