Three Kingdoms: Starting from the Need for a Small County Magistrate

Unexpectedly, when I came to ancient times, I experienced the feeling of being a star.

At the strong request of everyone, the first class 11 was given to everyone by Xiao Yi.

In terms of hyphenation, Xiao Yi is no better than Cai Yong and Lu Zhi, and even Liu Deran is better than him.

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

"The class I teach you is called a nature class, which helps you better understand nature and the world we live in."

Naturally, this is a brand new field, and the common people have shown strong interest.

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

"Everyone knows why there is day and night"

Xiao Yi's words shocked everyone.

If there is day, there will be night. This is something that everyone knows, why is there any reason? "If you know it, you can raise your hand to answer."

Xiao Yi shouted.

A boy of twelve or thirteen years of age 121 raised his hand weakly, "Because when the sun rises, it is... day, and when the sun sets, it is... night."

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

"Then you know how the sun sets and rises"

This question left everyone at a loss, even Lu Zhi and Cai Yong, who were knowledgeable, were confused.

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

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 on is called Earth.

Why is it called the Earth because it is a ball."

"Hahaha......"

Xiao Yi's words made everyone laugh.

However, after laughing, many questions arose.

Cai Yong, the teacher, was the first to ask questions."

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

Several knowledgeable people stood up and refuted.

"That's because you don't know how big the earth is.

The reason we see that the ground is flat is because I am too small for the earth.

People 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 the whole picture appears bit by bit, as if it came out of the water."

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

Although Zhuo County is not close to the sea, both Lu Zhi and Cai Yong have been to the seaside and seen the phenomenon Xiao Yi mentioned.

There were also some refugees who came from the sea, nodding their heads.

They are thinking: the earth is really round. "If it is like what you said, when the ship goes to the other side, will it fall down?"

Cai Yong continued to ask.

He is a person who is good at pursuing the truth, and it is difficult to convince him just based on that point.

"This involves a more esoteric problem, gravity! The greater the mass of the object, the stronger the gravity.

I'm doing a simple experiment, it's best if everyone can understand it, and it doesn't matter if you don't understand it."

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

"Do you know why the wooden block falls?"

Ah, objects will fall from the sky, and why are ordinary people dumbfounded, and suddenly feel that they are listening to a book from heaven.

How can so many common phenomena become big truths in Xiao Jun's mouth? It is indeed Xiao Jun, who knows so many things that we don't know! The students in the classroom are not aware of it! "Is this what you mean by gravity?"

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

"That's right,"

Xiao Yi glanced over there, and continued, "The reason why objects fall from heights is because of the pulling force of the earth.

This is also the reason why we stand on the ground instead of floating in the air.

Because the Earth is big enough, wherever we stand, we get this kind of pull."

"This theory is...a novelty!"

The young man nodded approvingly.

Obviously, when everyone was confused, he already understood.

"Then may I ask, what does this have to do with the sun rising in the east and setting in the west?"

he asked next.

Xiao Yi 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 rises and sets, but because the earth revolves around the sun."

Xiao Yi held the small ball in one hand and turned 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.

I call this rotation a revolution.

When the earth rotates once, it is one day.

Please see, if we live in this part of the earth, when the earth rotates to this side, we are facing the sun, so this time is daytime.

When the Earth rotates this way, we are facing away from the sun, so it is night."

Xiao Yi's speech is very vivid. The more you listen, the more fascinated you are. Even the very young children listen quietly and feel the mystery of nature brought to them by Xiao Jun.

After a class, although few people understood, but everyone listened very seriously.

Most importantly, Xiao Yi aroused their interest in exploring nature.

Although it was time for get out of class, many people still asked Xiao Yi to continue his lecture.

I haven't heard enough at all.

Of course, Xiao Yi couldn't occupy the time of other subjects, so he left two assignments and gave the position to other teachers.

The students had to stay and listen to the lectures, but the adults lost interest in the lessons that followed.

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

Chapter [-]

In the class just now, this young man made a deep impression on Xiao Yi.

Basically, a lesson is... a confrontation between the two of them.

This person has a clear mind, his brain responds very quickly, and many problems can be understood at one point.

Comprehension ability, can even dump Cai Yong and Lu Zhi....... celebrities are several streets away.

Not to mention, those... ordinary people.

So Xiao Yi guessed that this might be some great talent.

Xiao Yi deliberately left some flaws in the class just to wait for him to take the initiative to find him.

In the end, he really came! "Let's find a quiet place and sit down and talk slowly."

Xiao Yi smiled.

"I can't ask for it."

Although the latter questioned Xiao Yi, he was already attracted by the wonderful natural phenomenon, so he wanted to ask Xiao Yi more questions.

The two came to Wansan Restaurant.

, found a quiet private room, ordered a few side dishes, and boiled a pot of good wine.

"Xiongtai just said that there is a loophole in my class, let's hear it"

Although Xiao Yi is not a physicist or an astronomer, it is enough to fool these people with the knowledge he has learned.

Besides, some loopholes were deliberately left by him.

The youth said, "Xiao Jun said that any object with weight has a gravitational force.

That's the loophole."

"Appreciate further details!"

The smile on the corner of Xiao Yi's mouth became even stronger.

How can there be loopholes in the law of universal gravitation?

No matter how smart this person is, it is impossible to overthrow the laws that people have summed up for hundreds of years.

"You said that the sun is more than a million times larger than the earth, and the earth is so vast, how big should the sun be! And you have said that the heavier the object, the greater the gravitational force.

According to your argument, the earth should be attracted by the sun.

Why does the earth only revolve around the sun and not fall on the sun?"

He had a very clear mind, and it was really nice for someone who was new to physics to be able to ask such a question.

This "loophole"

, Even Xiao Yi himself didn't notice it.

In his time, every middle school student might have such doubts when he took a physics class.

But later, the teacher will give the answer.

It's just that the first cosmic speed is involved, which is more complicated.
