Introduction. What do a chandelier and the planet Venus have in common? They each played a part in the discoveries of one of history's greatest scientists 500 years ago. His name was Galileo

引言。 一盏吊灯和金星有什么共同点呢？ 500年前，它们都成就了史上一位最伟大科学家的发现。 这位科学家就是伽利略

Galileo's Childhood Galileo was born in Italy in 1564. From a young age, he was good at asking questions. Though his questions got him in trouble, Galileo changed the way we understand the world.

伽利略的童年 伽利略1564年出生于意大利。 从小他就擅长提问。 虽然他的问题给他惹了麻烦，却改变了我们认识世界的方式。

The Student As a young man, Galileo wanted to learn about math and physics, the science of matter, energy, and motion. He made one of his first discoveries in physics a year before he entered university. One day in 1582, Galileo watched a chandelier hanging from the ceiling inside a church. He saw that the wind outside was making the chandelier swing back and forth. He also saw something strange. Although some swings were

学生时代 年轻的伽利略想要学习数学和物理——也就是研究物质、能量和运动的科学。 早在进入大学前一年，他就有了第一个物理发现。 1582年的一天，伽利略在教堂里看到天花板上挂着一盏吊灯。 他看到外面的风把吊灯吹得来回摆动。 他还发现了一件奇怪的事。 虽然有的摆动

By watching the chandelier, Galileo discovered that a weight that swings back and forth can keep time. Later, he figured out how to build a clock using this idea. Clocks like his are still in use today. Galileo did not study math when he first entered university in 1583. His father wanted him to become a doctor instead. Galileo's study of medicine never interested him much though. In fact, he never finished his studies. He left university in 1585 because of money problems. For the next four years, Galileo taught math. However, he did not give up his interest in science.

通过观察吊灯，伽利略发现来回摆动的重物可以用来计时。 后来，他根据这个想法造出了时钟。 直到今天，类似的时钟还在被人们使用。 1583年伽利略刚进大学时，没有学习数学。 他的父亲想让他当一名医生。 可伽利略对学医一直没什么兴趣。 事实上，他始终没能完成学业。 1585年，因为经济问题他离开了大学。 接下来四年，伽利略靠教数学为生。 但他从来没有放弃对科学的兴趣。

the professor. In 1589, Galileo returned to the university as a math professor. He continued to ask questions and test things. For example, he did several tests with falling objects to see what would happen. However, the discoveries that would make him famous were still to come.

成为教授。 1589年，伽利略回到大学当上了数学教授。 他依然坚持提问，做实验验证想法。 比如，他做了好几个落体实验，观察结果。 不过，那些让他成名的发现还尚未到来。
