Galileo was an Italian physicist, astronomer and philosopher who pioneered modern experimental science. He used a combination of experiment and mathematics to determine some important laws of mechanics. He made a careful observation of the falling body movement and established the correct “law of free fall”.
Galileo believed in the truth, had his own ideas and stuck to his ideas no matter what others said. It reminds me of this: No one is always right. I think we should learn from Galileo's spirit of questioning. Don't always listen to others who make you do what they want.

【参考范文】
Edison, a world-famous scientist of invention, was so curious about the world that he always asked questions about everything. When Edison grew up, he concentrated on inventing things.
In his lifetime, he made more than 1,000 kinds of inventions. He spent his whole life in the laboratory, experiment after experiment, failure after failure. Instead of despairing, he tried harder. The great invention of electric light is a good example.
As far as I'm concerned, his indomitable spirit and perseverance is worth learning to us.
