Chapter 840 The Original Version of 2 Children's Debate (3 in 1)

Han Cheng's affirmation and praise made Shi Shi's face, which had turned red from excitement, become even more rosy.

At this time, he was full of joy, as happy as when the Son of God came to teach them how to write and speak Mandarin many years ago, he always did it quickly and well, and thus was praised by the Son of God.

Those who are ignorant and seem to have caught something, but they have been unable to grasp it thoroughly, after listening to the words of the stone, they carefully recalled the scene when the son of God was holding the fruit and turning it slowly. Things, now suddenly become clear.

Yes, it is because the earth rotates from west to east. In this case, the east sees the sun first.

As the earth continues to rotate, in their eyes, the sun is constantly moving westward. When the position of their own tribe turns to a place where the sun cannot shine, the sun will disappear.

It turns out that this is why there are day and night!

It turns out that the sun rises in the east and sets in the west, not because the sun itself is moving, but because the earth on which I and others live is rotating!

Many people were surprised, as if a brand new door was opening in front of them.

At the same time, their eyes are no longer limited to the small piece of land they already know, but have expanded to a very large place.

When they set their sights on the stars and the sea, know these extremely amazing secrets, and understand what the land they live in is like, when they look back at the place of residence, they feel that it is not that big.

But at the same time, after understanding your own insignificance, you will not make people feel arrogant, and you will not be easily satisfied.

"Then can someone tell me now, why is it the hottest at noon, but it gets colder at night?"

Han Cheng looked at the crowd, paused for a while, and continued to ask questions, letting the people in the tribe think for themselves.

"It's because at noon, there is the sun, but at night, the sun doesn't shine."

This question was relatively simple. As soon as Han Cheng finished speaking, many people raised their hands.

Han Cheng asked one of them to stand up and answer.

"Very good! Because the sun can shine at noon,

It cannot be illuminated at night. This is the same as we sit around the fire, the side that is warmed by the fire is warm, and the side that is not warmed will be cold. "

Han Cheng nodded approvingly, then looked at the happy man and continued, "Then can you tell me why it's hot at noon, but cooler in the morning and evening? Morning and evening are the same as noon, but It’s all in the sun.”

After such a question was asked, the person who answered the question was immediately stopped.

Yes, morning and evening are also irradiated by the sun, why is it the hottest at noon?

Not only her, but many people sitting in the big tiled house of green bricks were stumped by the question Han Cheng asked again, thinking hard there.

"Son of God, I know!"

After a while, Shitou raised his hand, looked at Han Cheng and said excitedly.

Han Cheng asked the man to sit down and let Shitou talk.

"It's because we are far away from the sun in the morning and evening, and close to the sun at noon.

Just like warming up with a fire, the closer you are to the fire, the hotter it will be, and the farther away it will be less hot. "

Shitou stood up and talked, and by the way, imitated Han Cheng's appearance, using the well-known fire as an example.

Han Cheng smiled again. This guy Shitou is really talented in these aspects, and he has the style of his back then.

"Then, how do you know that you are closer to the sun at noon, and farther away from the sun in the morning and evening?"

Someone questioned the stone.

Seeing this, Han Cheng didn't make a sound, but looked at the person who asked the question and Shitou with a smile, wanting to see how Shitou would answer.

"It's very simple. Not long ago, the Son of God used a rope and fruit to demonstrate to us that the distance from the sun to the edge of the earth is farther than the distance to the middle. Using the same method, we can get these."

Facing such a question, Shi Shi didn't hesitate at all, and opened his mouth to speak out the solution.

When Han Cheng heard this, a smile appeared on his face again.

Shitou's brain is really good, and he actually thought of the experiment he did not long ago.

At that time, it was to explain to them why it gets hotter as you go south. I didn't expect that Shitou would use it here by analogy.

The same method can indeed be used to explain and verify this aspect of the problem.

When Shi Shi said this, many people thought of the experiment that Shenzi had done in the rabbit circle before, and then connected it with the present, and found that it was indeed the case.

Seeing everyone's reaction, Shitou felt more at ease, and felt a kind of joy of being a bully and bullying a scumbag.

"Then, why does the sun look so big in the morning and evening, but it looks so small at noon? Doesn't it look bigger the closer the distance is, and smaller the farther the distance is? "

Another person said aloud, his voice full of confusion.

As soon as these words came out, the people who just thought Shi Shi was right also became confused.

The closer you are to the fire, the warmer it is, and the closer you are to the sun at noon, the hotter it sounds, which doesn't sound like a problem.

But at a short distance, the sun should appear to be the largest, but the reality is that the sun appears to be the smallest at noon.

As soon as these two things were linked together, it instantly gave people a headache. Even Stone, who was full of confidence just now, was confused by this question, and his mind was full of muddleheadedness.

He felt that the sun was closer to the sun at noon, but he couldn't figure out why the sun looked much smaller at noon than in the morning and evening.

For a moment, everyone in the big tiled house in Qingque was confused by this tricky question, and their minds were full of muddleheadedness.

For everyone in the tribe, Han Cheng was not surprised by this question, because it was an eternal problem.

When Confucius traveled eastward, seeing two children arguing about the sun, Confucius was stunned to be speechless by this tricky question, and was even laughed at by the two children.

People in their own tribe, now encountering this eternal problem, it is normal to be stunned.

When he was in school, he was also confused when he learned this text, thinking that what the two children said made sense.

Regarding the doubts about this question, he finally figured it out after he went to high school and studied geography.

"Son of God, is it closer to the sun in the morning or at noon?"

The stunned stone finally couldn't help asking Han Cheng.

Originally, he had no doubts about the result he got, but now, he has been shaken.

The rest of the people also looked at Han Cheng in unison, hoping to get an accurate answer from their son of God, and to solve this problem that made their brains hurt.

"Of course it is closer to the sun at noon, and farther away from the sun in the morning and evening."

This and the question can stump the old Confucius, who is seriously biased, but not Han Cheng, a liberal arts student with a very good score in geography.

After hearing Shitou's question, he gave an accurate answer very simply, without saying a word.

In the past, after getting an accurate answer, many people in the tribe would not continue to ask the bottom line, but this time it is different, they all want to know why this is the case.

Why does the sun look so big in the morning, but it turns out to be far from the ground...

Seeing is not necessarily believing. In many cases, eyes can also deceive people and give people an illusion.

"This is because in the morning, the sun shines in obliquely, and the refraction by the atmosphere wrapped around the earth is particularly obvious, which magnifies the sun.

But at noon, the sun shines more directly, instead of magnifying the sun, it presents the original face of the sun, so at noon, the sun looks smaller. "

Of course, everyone in the tribe couldn't understand such words, and even the most talented stone was stunned.

After thinking about it, Han Cheng asked someone to fetch a piece of ice from the water basin outside, carefully made it into a convex lens, and put it in front of one of his eyes.

Then, everyone in the tribe was surprised to find that Shenzi's eye was much bigger than the other eye.

When Han Cheng removed the ice cube from his eyes, the eyes immediately returned to their normal size.

"In the morning, the atmosphere acts like this ice cube, magnifying the sun, but when the sun shines directly at noon, the atmosphere has no magnifying effect."

As Han Cheng said, he put a flat ice cube in front of one eye, and his eye looked about the same size as before.

This miraculous scene made everyone amazed, but at the same time, through this analogy experiment, many people in the tribe understood what was going on.

After Han Cheng saw that many people understood, he gave the ice cubes in his hands to the people sitting in front and asked them to play with them.

"Son of God, the earth we live in is a big sphere, and it keeps turning in circles. Why hasn't that person been thrown out?"

When everyone was curious about the ability of ice cubes to magnify things, Wu, who had been silent all this time, finally asked a question.

He struggled with this question for quite a while, but he didn't come up with a reason. At this time, seeing that everyone was not asking questions, Shenzi didn't talk about it any more. After thinking about it, he stood up and said it.

After the witch's voice sounded, the big tiled house with blue bricks became quite quiet all of a sudden. After the question that Wu asked was understood, the big tiled house with blue bricks became even quieter.

If it hadn't been proposed by Wu, they really didn't realize this problem.

Now that Wu said this, and they followed Wu's train of thought, they immediately fell into the same confusion and doubts as Wu did.

Seeing this, Han Cheng sniffed. Fortunately, he is a time traveler, otherwise he would have been really questioned by you.

He looked at the crowd, cleared his throat, and was about to stand on the shoulders of giants and grab Mr. Newton's apples.

"This is because the earth we live in has a kind of attraction that can attract us all, not just us, everything on the earth will be attracted.

It is precisely because of the existence of this invisible and intangible attraction that we will not be thrown away in the rotation of the earth. "

Just as Han Cheng thought, after he threw out the gravitational force, everyone in the tribe stopped talking, and their eyes were either surprised, confused, or thinking...

"But, son of a bitch, birds can fly in the sky, and I can also jump up."

After such an atmosphere lasted for a while, someone finally couldn't help but speak.

"But a bird can't fly in the sky all the time, it always lands on the ground or a tree, and you can only leave the ground for a short while when you jump up, and then it will fall back to the ground immediately.

If the earth is not attractive, shouldn't you not fall after jumping up, but float in the air, or go straight to the sky? "

Han Cheng asked back with a smile.

After such a rhetorical question came out, everyone froze for a moment.

Yeah, why does everything fall to the ground? Even the farthest flying bird will fall to the ground when it gets tired.

The leaves blown into the sky by the wind, and the stones thrown up by himself and others will all fall to the ground in the end.

If there is no universal gravitation that the Son of God said, these things should all fly to other places, right?

If there is no universal gravitational force that the Son of God said, I and others have become accustomed to it, and I and others can't live on this big rotating ball, right?

Han Cheng looked at the reaction of the crowd, and a smile overflowed from the corner of his mouth. It seemed that he was very successful in snatching Mr. Newton's apple this time.

Think about it too, many things are the most difficult when they are first invented or discovered, but once someone pierces this layer of window paper and gets it out, the latecomers will feel that it is also difficult to see. not difficult.

Just like Han Cheng today, Han Cheng told everyone in the tribe about the natural knowledge including gravitation. When he told the story in combination with the actual situation, it was not so difficult to understand it.

If it is difficult, this knowledge will not be taught in high school, but popularized to everyone.

And he, as a member of beings with mediocre aptitude, couldn't understand all of these and remember them firmly.

That's all for today's narration. When everyone came out of the big brick house, looking at the familiar scene outside, they all felt a little different.

It seems that the whole person understands many things at once, and has a different view and understanding of the world.

As night fell, the Qingque tribe, like the rest of the place, was also shrouded in darkness.

Lying on the warm kang, the stone opened a corner of the window beside him.

Through this corner gap, he could see two bright stars in the night sky.

At this time, the stone eyes were as bright as the two stars in the night sky.

Thinking back to what the Son of God said today, Shitou's heart fluctuated violently.

Before that, he never thought that there are so many things hidden behind these things that he and others have long been accustomed to.

Many seemingly ordinary things have their own reasons.

Today, following Shenzi's narration, he discovered a different world, as if a door had been opened in his mind.

Perhaps, after I know enough about this world, I will be able to fly to the sky!

I don't know how long I've been lying here, Shi Shi put down the corner of the animal skin curtain, lying on the bed, thinking about these things, couldn't help clenching his fists.

Han Cheng, who was lying on the kang, was also not at peace thinking about what happened today.

As a time traveler, the most precious thing is actually what you know, the knowledge that is far beyond this era.

Especially his kind who traveled directly to prehistoric times.

Traveling to prehistoric times is inconvenient in many ways, but from another point of view, it is not without some advantages.

At least you can build the tribe according to your own ideas, and no one will hold you back.

Not to mention that there will be no orthodox self-proclaimed person who jumps out and criticizes you with righteous words, saying that you are deviant, saying that you only know how to play tricks, and that you don't understand the way of the king.

Here, when you want to do something, you can do it directly, without having to argue with various people. In the end, what you want to get is completely changed, or even died directly.

As a latecomer, Han Cheng naturally knew how important the skins he had mastered were to his own tribe, or to the whole era.

So he wants to pass on these things as much as possible.

With his fur, the tribe will avoid many detours and be able to make a very good start.

After the tribe developed, stepping on the shoulders of the former, many outstanding talents emerged.

In the superficial knowledge he has learned, natural science knowledge can be said to be crucial.

The saying that science is the first development force is really true.

Natural science knowledge, or basic scientific theories, is a crucial part of the entire scientific development.

After the emergence of universal gravitation, various emerging things were triggered, which greatly promoted the development of science.

When it had a bottleneck and was constrained, the special theory of relativity and the general theory of similarity came out, and on the basis of it, a new round of explosive growth sprung up like mushrooms after rain.

Perhaps in the future, I will tell the people in the tribe more about this knowledge, and slowly tell the superficial knowledge I know to the people in the tribe who are talented in this area.

As for some things that are too advanced and that I don’t know much about, I can record them first. Maybe later, when the tribe has developed to that point, after seeing these things, future generations will suddenly understand and solve the mystery in their hearts. Thereby promoting the great development of the whole tribe.

Han Cheng lay on the kang and thought like this, the more he thought about it, the more he felt that his idea was very reliable.

Gun barrels rot, purses change owners, but the only thing that doesn't change is truth, especially truth about science.

After all, matter is not transferred by matter.

Of course, Han Cheng also knows that according to the current situation of the tribe, it is unrealistic to quickly develop all these ideas. It will take him more time to live than completely cultivating rapeseed into Chinese cabbage if he wants to realize these ideas. series.

But as long as this is done, there is always a hope.

Planting a seed today may not fail to grow into a towering tree and bear abundant fruits.

Who can tell what will happen in the future?

Lying on the kang, his thoughts were flying wildly. After a long, long time, Han Cheng fell asleep completely.

In the following days, the weather was sunny and cloudy, and some fine snowflakes even fell down on two days.

For two days, the temperature also rose, but not much, and it didn't last for a few days before dropping again.

Those leaves, which were not so withered and yellow before, quickly completed the transformation to withered and yellow under such a climate. Under the howling cold wind, they fell one after another, and people stepped on them, making a crisp scorching sound.

The autumn of Qingque's eleventh year is really gone forever, being squeezed away by the strong winter.

In such weather, many activities of the Qingque tribe did not stop.

For example, burning charcoal, transporting manure to the land around the tribe, continuing to plow the land before the heavy snow falls, and so on.

And Han Cheng took the time to tell those interested in the tribe more knowledge about geography.

It still uses the method of asking questions and then answering them.

For example, why are there four seasons of spring, summer, autumn and winter? After asking this question, I began to slowly tell everyone about the earth's revolution, perihelion, aphelion, and tropics.

It is difficult for many people to understand these things, but Han Cheng has a lot of time and is patient enough to try his best to explain them over and over again, little by little, and over and over again.

At the beginning, people in the tribe accepted brand-new Mandarin and Chinese characters from scratch, but they couldn't stand up to Han Cheng's repeated offensives. Those who were forcibly honed by Han Cheng could speak Mandarin and write Can recognize some Chinese characters.

Now that this spirit is shown again, many people gradually understand what is going on.

Even some people who didn't understand, under Han Cheng's repeated offensives, firmly remembered the things he said in their hearts.

After keeping these things firmly in my heart, in the years to come, sometimes unconsciously, I will suddenly understand some of them.

With regard to dealing with knowledge and learning and applying it flexibly, according to Han Cheng's own experience, he has to work hard first, eat these things with a spirit similar to rote memorization, and then live on the basis of firmly memorizing them. Learn and use.

Otherwise, if you don't even know some basic foundations, how can you learn and use them flexibly?

Of course, this is only for people with ordinary qualifications. For people like stone who understand very quickly, and sometimes can draw inferences from one instance, such a thing does not exist at all.

However, for those people who are clearly qualified to be ordinary people in school in later generations, they are also very particular about learning and applying it flexibly, and then they have a very contemptuous attitude when they hear that they have worked hard. Man, Han Cheng can only sniff his nose.

As big a turtle as it is, there is as big a nest as it can be, and stupid people use stupid methods, Han Cheng thinks it makes sense.

It is important for people to have self-knowledge, not to underestimate themselves, but also not to be arrogant, to recognize oneself clearly, and to admit oneself bravely. Sometimes it is very important. After all, there are too few geniuses in this world, and there are more beings with similar aptitudes.

Well, this is a bowl of poisonous chicken soup from primitive times...
