Three Kingdoms: Starting from the best little county magistrate

The first day of May is an important day for the people of Zhuo County.

The first day of school starts at Shenyi Academy!

Xiao Jun not only invited some highly respected people to serve as teachers, but he also taught in person, teaching children some knowledge that ordinary people don't know.

Who is Xiao Jun?

That's a god in the sky, and everything he brings is infinitely useful. He teaches something that is certainly the best.

Therefore, the common people not only sent their children to the school, but also deliberately made time to stay in the school and wait for Xiao Yi to give lectures.

Originally, there were only 300 children who signed up, and Shenyi Academy could fully accommodate it. But with the addition of the children's parents and some admirers, the spacious school was overcrowded.

When Xiao Yi came over, he almost couldn't find the door to enter.

After learning about it, I realized that these people were all coming for him, and I immediately felt very relieved.

It's really touching that so many people like themselves.

Unexpectedly, when I came to ancient times, I experienced what it was like to be a star.

At everyone's strong request, the first class was given by Xiao Yat.

In terms of literacy and hyphenation, Xiao Yi is not as good as Cai Yong and Lu Zhi, and even Liu Deran is better than him.

But what Xiao Yat wants to talk about is natural knowledge.

"The course I am teaching you is called a nature course to help you better understand nature and the world we live in. "

Nature?

It's a completely new field, and people are showing a lot of interest.

Because the more they don't know, the more they want to hear it.

"You know, why is there day and night?"

Xiao Yi's words made everyone stunned.

Where there is day, there is naturally night, this is something that everyone knows, why is there a reason?

"If you know, you can raise your hand and answer. "

Xiao Yat shouted.

A boy of twelve or thirteen years old raised his hand weakly, "Because the sun rises as day, and the sun sets as night?"

This is a fact that everyone knows, and he is not sure if Xiao Jun needs this answer.

"Do you know how the sun sets and rises?"

This question made everyone look dazed, even the knowledgeable Lu Zhi and Cai Yong were also confused.

They thought to themselves, isn't it common sense that the sun rises in the east and sets in the west, and why is there any reason?

Seeing that no one answered, Xiao Yi smiled slightly and took out two bamboo balls, one large and one small.

"Actually, the land we live in is called Earth. Why is it called Earth? Because it's a ball. "

"Hahaha......"

Xiao Yi's words made everyone laugh.

However, after laughing, many questions arose.

Cai Yong, the teacher, took the lead in asking, "How can the earth be a sphere?

"Yes, the earth we see is obviously flat. "

Several knowledgeable people have stood up to refute it.

"That's because you don't know how big the Earth is. The reason why we see that the ground is flat is because I am too small for the earth.

Those who live by the sea should know that when a ship comes from a distance, the first thing we see is the mast, and then little by little the whole picture appears, as if it came out of the water. "

This point is enough to prove that the surface of the earth is a curved surface.

Although Zhuo County is not near the sea, Lu Zhi and Cai Yong have all been to the beach and have seen the phenomenon that Xiao Yi said.

There were also some homeless people who came from the seaside, nodding vigorously.

They are thinking: the earth, is it really round?

"If, as you say, when the boat goes to the other side, won't it fall?"

Cai Yong continued to ask.

He is a man who is good at pursuing the truth, and it is difficult to convince him based on the fact that he has just been there.

"There's a deep question involved, gravity! The greater the mass of an object, the stronger the gravitational pull.

I'll do a simple experiment, and it's best if people can understand it, and it doesn't matter if you don't understand it. "

Xiao Yi picked up a wooden block and lifted it, then let go,

The block fell.

"Do you know why the wooden block falls?"

Yes?

Objects fall from the sky, why else?

The common people were dumbfounded, and suddenly felt that they were listening to the book of heaven. Why have so many common phenomena become a big truth in Xiao Jun's mouth?

It's worthy of Xiao Jun, who knows so many things we don't know!

The hall is full of students, and I don't know how to do it!

"Is this what you call gravity?"

At the end of the crowd, a young man with a bun and a strand of hair scattered in front of his forehead said loudly.

"That's right,"

Xiao Yat glanced over there and continued, "The reason why objects fall from a great height is because they are attracted by the pull of the earth. This is also the reason why we humans stand on the ground and do not float in the air.

Because the Earth is big enough, we get this traction no matter where we stand. "

"This theory is novel!"

The young man nodded appreciatively.

Obviously, when everyone was confused, he had already understood.

"So what does this have to do with the sun rising in the east and setting in the west?"

He then asked.

Xiao Yat held up two balls, "Because, the sun is also a ball, and it is more than a million times larger than the earth! The reason why the sun rises in the east and sets in the west is not because the sun is rising and falling, but because the earth is revolving around the sun." "

Xiao Yat held the small ball in one hand and spun around the big ball.

"It takes a year for the earth to revolve around the sun like this. This is also the reason for the formation of spring, summer, autumn and winter. This rotation is what I call revolution.

And one rotation of the earth takes one day. You see, if we live in this part of the earth, when the earth turns to this side, we are facing the sun, so it is daytime.

When the earth turns to this side, we are facing away from the sun, so it is night. "

Xiao Yat spoke very vividly, and the more everyone listened, the more fascinated they became, even the very young children listened quietly and felt the mystery of nature that Xiao Jun brought to them.

At the end of the class, although few people understood, everyone listened very carefully.

Most importantly, Yat sparked their interest in exploring nature.

Although it was time for the end of class, many people still asked Xiao Yat to continue.

I haven't heard enough of it.

Of course, Xiao Yat couldn't occupy the time of other subjects, so he left two homework assignments and gave up his place to other teachers.

The students had to stay and listen to the lessons, but the adults were not interested in the later lessons and dispersed.

When Xiao Yi left the school, he was stopped by the young man who asked the question before, and the man smiled proudly, "Xiao Jun, the story just now was very exciting, but there is a loophole. "
