Today was Zhou Wu's class again. Generally speaking, Zhou Wu's classes are not limited to any particular form. Like today, Zhou Wu did not teach in the classroom, but came to a small hill near the school.

"Today we're going to talk about something interesting. First, I need a few helpers. Who's willing to come?"

The students really enjoyed Zhou Wu's classes because he often used vivid and interesting experiments to help them understand the underlying principles.

"I come."

"I'll come, I'll come."

The students were very enthusiastic because they knew that Zhou Wu wouldn't ask any obscure or difficult questions.

"Then it's you, you, and you, the three of you."

Zhou Wu randomly selected three people and gave each of them a sheet of the best Xuan paper.

What do you think the principal will talk about today?

"I don't know either, but I'm really looking forward to it."

"Yeah, that's right. It would be great if the principal could offer a few more classes."

"You wish! The principal has so many things to deal with every day. It's already quite good that he can take time out of his busy schedule to teach us. Be content."

The students who weren't selected were a little disappointed, but they were still waiting for Principal Zhou to finish his presentation.

"What you need to do now is to try your best to throw the paper in your hands as far away as possible, the farther the better."

No one expected that Principal Zhou would make this request.

However, the three students who were selected quickly got to work.

First up was a strong man. He used all his strength to throw the paper in his hand, but the unfolded paper was even blown back after encountering wind resistance.

The second person, also a male student, thought for a moment after seeing the first person's performance. He crumpled the rice paper in his hand into a ball and threw it out hard. It did go out, and quite far.

After throwing it, he looked at the other two classmates provocatively. The classmates next to him also seemed to be treating it as a competition, as if they were watching to see who would win.

However, everyone seems to have now concluded that the third student cannot throw the paper farther than the second, because the last student is a girl, who is definitely weaker than the boy, and the way she throws the paper is definitely crumpled into a ball.

However, when the third girl came on stage, she didn't rush to crumple the paper in her hand into a ball. Instead, she was looking for something on the ground.

Suddenly, she found a piece the size of an egg, picked it up, and wrapped it in paper. Only then did everyone realize what had happened.

As expected, the final winner was the last girl.

"Teacher, I protest! She cheated!"

Clearly, the second student was very upset about missing out on the victory.

"Tell me your reasons?"

Zhou Wu never directly refutes any questions raised by students; he always asks them to explain their reasons before making a judgment.

“He wrapped the stone in paper, that doesn’t count.”

"Before we started, I said it was any way you wanted."

Some of the other students initially disagreed with the girls' winning strategy, but after Zhou Wu said that, it seemed that there really were no requirements or rules before it started.

The male student only realized what was happening after hearing this, and then retreated back into the crowd somewhat embarrassed.

"Congratulations to this female student for winning, but unfortunately there is no prize."

People say they are charmed by Zhou Wu's humor, which is why they enjoy his classes.

"Among you, is there anyone who can throw the paper any further? Is there?"

Zhou Wu made the request again.

"Principal, isn't this the best solution?"

"Yes, I think there's no way to throw a stone farther than by carrying it."

However, none of the students seemed to have a better solution.

"Principal, do you have a better idea?"

A classmate raised a question.

"Hey, classmate, you're really smart."

After Zhou Wu finished speaking, he began to fold the paper in his hand, and soon a paper airplane was folded.

Zhou Wu even showed the paper airplane to everyone.

"The principal is really skillful."

"Hmm, although I don't know what this strange thing is, it is indeed quite skillful."

I don't know why everyone's discussion is focused on Zhou Wu's skillful hands, and why they are not avoiding mentioning Zhou Wu at all.

Even though Zhou Wu was cursing in his heart, he still maintained the demeanor of a teacher.

Gently tossing the paper airplane into the air, everyone initially didn't think much of it, but gradually, they all stared in shock.

The paper airplane traced an arc in the air before gliding away into the distance.

"What! What kind of magic did the principal use? Yes, it must be the legendary Paper Crane Technique."

A piece of paper flying this far—no one can think of any other reason besides magic.

"What a load of nonsense! This is science."

Zhou Wu gave him a sharp rap on the head. The reason he founded the technical school was to teach people to be materialistic warriors and to believe in the power of science, not the power of ghosts and gods.

"Is this science?"

This wasn't the first time the students at the school had heard the word "science," because many of the school's teachers were also in the science lab. They would occasionally take time to come to the school to give lectures, but these lectures were very profound, leaving many students completely confused.

However, today the principal used such a simple and straightforward method to tell everyone that this is science, which made the students seem to have gained a glimpse into the field.

"To be precise, this is not even the tip of the iceberg of science. Why can my paper be thrown farther than others? Can any student explain?"

This question seemed simple, but no one could answer it. Only the girl who threw the last piece of paper spoke up timidly.

"Because the principal changed the shape of the paper?"

"That's right, you're very observant and brave."

This girl has left a deep impression on Zhou Wu. Scientific exploration requires the courage to face the unknown, and this girl is at least very brave.

The girl was very happy to hear the principal's praise.

"Actually, I just took advantage of the wind."

"Did they take advantage of the wind?"

"That's right. The reason birds can fly is because when they flap their wings, they can change the airflow and use it to make themselves fly."

The students shook their heads blankly. Zhou Wu shook his head inwardly as well. He had thought this example was simple enough, but he hadn't expected that he had overestimated the thinking of people in this era.

"Kite, right? Why can kites fly? Is it because people run when they fly kites, and running creates wind, which makes the kite fly?"

"Correct."

"Yes."

Many people seem to have figured these things out.
