Study the background and perceive the characters

When Galileo was in school, his classmates called him "the debater." The questions he asked were unusual and often difficult for teachers to answer.

It can be seen that Galileo was a (good at thinking) scientist.

At that time, people who studied science believed in Aristotle and regarded the words of this Greek philosopher more than 2,000 years ago as unchangeable truth. If anyone doubted Aristotle, people would reproach him: "What do you mean? Are you going to violate human truth?"

Connect with life and talk about your feelings

Only then did everyone realize that not everything a great philosopher like Aristotle said was right.

People's attitudes towards Galileo have also changed. What will they say and do?

1. Unexpected exclamation: "Ah..."

2. Can clap and applaud! Throwing hats in the air and hugging each other.

3. Will say: "We wrongly blamed this mathematics professor. This young man is so brave. It is amazing that he can ask Aristotle questions."

Text analysis

What was the significance of Galileo's experiment?

The significance of Galileo's experiment was not only to prove that Aristotle was wrong, but more importantly, to enable people to establish a correct scientific outlook, that is, not to be superstitious about authority and to pursue the truth persistently.
