I am a Primitive Man

Han Cheng's affirmation and praise made Shishi's face reddened with excitement, and became even more rosy.

At this time, he was full of joy, just as the son of God came to teach them how to write many years ago, and when he spoke Mandarin, he always did it fast and well, and he was as happy as being praised by the son of God.

Those who are ignorant, seem to have caught something, but have been unable to grasp thoroughly. After listening to the stone's words, they carefully recalled the scene when the son of God slowly turned the fruit while holding the fruit, which he could not grasp before. Things become clear now all at once.

Yes, it's because the earth rotates from west to east. In this case, the east will see the sun first.

With the continuous rotation of the earth, in their eyes, the sun is constantly moving westward. When the location of their tribe is shifted to a place where the sun cannot reach, 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 is moving by itself, but because the earth on which I and others live is turning!

Many people were in a daze, feeling as if a brand new door was opening before their eyes.

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

When they cast their gazes on the sea of ​​stars, learned these extremely astonishing secrets, and understood what the earth they lived in was like, when they looked back at the place of residence, they felt that it was not that big.

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

"Then can someone tell me now why it is hottest at noon, but at night, it becomes cold?"

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

This question is relatively simple. As soon as Han Cheng's words fell silent, many people raised their hands.

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

"Very good! It's because the sun can shine at noon but not at night. This is the same as when we surround a fire, the side that is roasted by the fire is warm, and the side that cannot be roasted will be cold."

Han Cheng nodded approvingly, and then looked at the ecstatic person and continued to speak: "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 exposed to the sun."

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

Yes, in the morning and in the evening, the sun is also irradiated. Why is it the hottest at noon?

Not only her, but many people sitting in the big blue brick house were embarrassed by the question Han Cheng asked again, and they were thinking hard there.

"God, I know!"

After a while, Shishi raised his hand and said with excitement looking at Han Cheng.

Han Cheng let the man sit down and let the stone speak.

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

Just like a fire, it’s hot as it gets closer, and it’s not as hot as it gets far away. "

Stone stood up and talked, learning Han Cheng's appearance by the way, taking the familiar example of roasting fire.

A smile appeared on Han Cheng's face again. This fellow Shishi is really talented in these aspects, quite the style he had back then.

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

Someone asked the stone a question.

When Han Cheng saw this, he didn't say anything, but smiled at the person who asked the question and the stone, wanting to see how the stone answered.

"It's very simple. Not long ago, the son of God also used rope and fruit to show us that the distance between the sun and the edge of the earth is farther than the distance to the middle. You can get this in the same way."

Faced with such a question, the stone did not pester at all, so he opened his mouth and said the way.

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

The brains of this guy Shishi are really good, he actually thinks of the experiment he did not long ago.

At that time, it was to explain to them why it gets hotter as it goes south. Unexpectedly, this fellow Stone actually used it here by analogy.

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

After being said by the stone, many people remembered the experiment that the **** child did in the rabbit circle before, and then connected it with the present, and found that it was indeed the case.

Seeing everyone's reaction, Shishi felt more comfortable, and a joy of learning tyrants and scumbags arose.

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

Another person spoke out, with confusion in his voice.

When these words were spoken, those who just thought that the stone was right were also confused.

The closer you are to the fire, the warmer it will be. The closer you are to the sun at noon, it’s hot. This doesn’t sound like a problem.

But when the distance is close, the sun should seem to be the largest, but the reality is that the sun looks the smallest at noon.

As soon as these two things are linked together, it instantly makes people head big. Even the stone that was full of confidence just now has been big headed and confused by this question.

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

For a while, everyone in the large tiled house of Qingque was all dizzy and confused by this tricky question.

For the people in the tribe, Han Cheng was not surprised by this question, because it was an age-old problem.

When Confucius traveled east, when he saw the two children arguing, the sage of Kong was dumbfounded by this tricky question, and was ridiculed by the two children.

People from their own tribe have encountered this age-old problem, and it is normal to be stunned.

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

The doubt about this question waited until he entered high school and studied geography before finally understanding it.

"My son, is it close to the sun in the morning or close to the sun at noon?"

The dizzy stone was finally unable to help but asked Han Cheng.

At the time, he was convinced of his results, but now, he was shaken.

The other people also looked at Han Cheng together, wanting to get an accurate answer from their **** son, and solve this problem that made their brains hurt.

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

This and the problem can stump the old Master Confucius who is seriously partial to the subject, but it can't stump Han Cheng, a liberal arts student with very good geography.

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

In the past, after getting accurate answers, many people in the tribe would not continue to ask questions, but this time it was different. They all wanted to know why this was 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, the eyes can also deceive and give people an illusion.

"This is because in the morning, the sun is shining in obliquely, and it is particularly significantly refracted by the atmosphere surrounding the earth, magnifying the sun.

But at noon, the sun shines more directly, instead of magnifying the sun, but showing the original face of the sun, so at noon, the sun looks relatively small. "

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

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

As a result, everyone in the tribe was surprised to find that this eye of the Son of God was much larger than the other eye.

When Han Cheng removed the ice cube from in front of his eyes, his eyes immediately returned to their usual size.

"In the morning, the atmosphere acts like this ice block, magnifying the sun, but at noon when the sun is direct, the atmosphere has no magnification effect."

As Han Cheng said, he replaced a flat ice cube and placed it in front of one eye. His eye looked almost the same size as before.

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

After seeing that many people understood, Han Cheng 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 where we live is a big round ball, and it's still spinning in circles. Why isn't that person thrown out?"

When everyone was curious about how ice cubes could magnify things, Wu Wu, who had never spoken, finally asked a question.

He had been struggling with this question for a long time, and he didn't think of a reason. At this time, seeing that everyone was not asking the question, the son of God did not talk about it anymore. After thinking about it, he stood up and said it.

After the voice of the witch sounded, the big blue brick house suddenly became quieter. After I understood the questions asked by the witch, the big blue brick house became quieter.

If it hadn't been raised by Wu Wu, they would really not realize this problem.

Now that Wu said this, they followed Wu's thoughts again, and they immediately fell into the same confusion and doubts as Wu.

Seeing this, Han Cheng sniffed. Fortunately, he is a traverser, otherwise you will really be asked.

He looked at the crowd, cleared his throat, and was about to start standing on the shoulders of the giant to grab Mr. Newton's apple.

"This is because the earth we live in has an attraction that can attract us all, not just us, but 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 universal gravitation, everyone in the tribe was no longer talking, their eyes were either surprised, confused, or thinking...

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

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

"But a bird can't always fly in the sky. When it falls on the ground or a tree, you can only leave the ground for a short while when it jumps, and it will fall back to the ground immediately.

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

Han Cheng asked with a smile.

After such a rhetorical question, everyone suddenly stopped.

Yeah, why do things fall to the ground? Even the farthest bird that flies will fall to the ground when tired.

The leaves that were blown into the sky by the wind, the stones that were thrown up by myself and others, would eventually fall to the ground.

If there is no gravitation that the **** son said, these things should all fly to other places, right?

If there is no such thing as the kind of gravitation that God's son said, you and others have become accustomed to it, you and others can't live on this rotating big ball, right?

Han Cheng watched everyone's reaction, his mouth overflowed with smiles. It seemed that he was still very successful in grabbing Mr. Newton's apple.

Think about it, many things are the first inventions or creations, or the most difficult when they are discovered, but once someone pierces this layer of window paper and gets it out, the latecomers will find it too. Not difficult.

For example, Han Cheng, today Han Cheng told the people in the tribe about natural knowledge, including gravitation, and it is not so difficult to understand it when describing it in combination with the actual situation.

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

And he, as a member of a mediocre being, it is impossible to understand all these things and remember them firmly.

That's it for today's story. When everyone came out of the big blue brick house and looked at the familiar scene outside, they 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 can see two bright stars in the night sky.

At this time, Stone's eyes were as bright as the two stars in the night sky.

Thinking back to the things that the son of God talked about today, Stone's heart fluctuated greatly.

Before that, he had never thought that there were so many things hidden behind these things that he and others had already taken for granted.

Many things that seem to be ordinary have their own reasons.

Today, as the son of God spoke, he discovered a different world, as if a door had just been opened in his mind.

Perhaps, after I know enough about the world, I can fly to the sky!

I don't know how long I lay here, the stone 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 lying on the kang, thinking about what happened today, was also not very calm.

As a traverser, the most precious thing is actually what he knows, knowledge far beyond this era.

Especially this kind of direct travel to prehistory.

Traveling to prehistory is inconvenient in many ways, but from another perspective, it is not without any benefit.

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

There will be no people who claim to be orthodox, who will come out to speak righteously and verbally criticize you, saying that you are apostate, saying that you will only be clever and obscene and do not understand the way of the king.

Here, when you want to do something, you can do it directly, without having to wrestle with various people. In the end, what you want to do is completely unrecognizable, and even directly dead.

As a latecomer, Han Cheng naturally knew how important the fur he had mastered was to his tribe, or to the entire era.

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

With his fur, the tribe will avoid many detours and can make a very good head.

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

Among the skins he has learned, knowledge of natural science can be said to be very important.

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

Natural science knowledge, or basic science theory, is also a vital part of the entire scientific development.

After the emergence of universal gravitation, various new things have emerged, which have 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 were born. On their basis, a new round of explosive growth has sprung up.

Maybe in the future, I will tell the people in the tribe more about this knowledge, and slowly tell the people in the tribe who are gifted in this area.

As for some things that are too advanced and are only half-knowledgeable, you can write them down first. Maybe later, when the tribe develops to that point, later generations of children and grandchildren will suddenly realize it and solve the mystery in his heart. Thereby promoting the development of the entire tribe.

Han Cheng was lying on the kang thinking like this, the more he thought about it, the more he felt that his ideas were very reliable.

The barrel of the gun will rot, the purse will change its owner, and the only thing that will not change is the truth, especially the truth about science.

After all, matter is not transferred as matter.

Of course, Han Cheng also knows that, according to the current situation of the tribe, it is unrealistic to develop these quickly. His ideas to realize these ideas are simply more lifelong than the thorough cultivation of rapeseed into Chinese cabbage. series.

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

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

Who knows the future?

Lying on the kang, his thoughts fluttered wildly. After a long, long time, Han Cheng was completely asleep.

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

For two days, the temperature also rose, but it did not rise much, and it fell again after a few days.

Those leaves that were not very yellow before, under such a climate, quickly completed the transition to withered, and under the roar of the cold wind, they fell one after another, and people stepped on them, making a crisp scorch.

The eleventh year of Qingque's autumn was truly gone, and was squeezed away by the strong winter.

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

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

And Han Cheng, taking time to interest the tribe, told more about geography.

Still use the method of asking questions and then answering them.

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

Many of these things are difficult for many people to understand, but Han Cheng can't hold back the time and patience enough to talk about it over and over again, little by little, and over and over again.

When the people in the tribe accepted the brand-new Mandarin and Chinese characters from scratch, they couldn’t hold back Han Cheng’s repeated offensives. They were honed by Han Cheng to speak Mandarin and write. Know some Chinese characters.

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

Even some people who didn't understand, under Han Cheng's continuous offensive, also kept these things he told firmly in their hearts.

When these things are forcibly remembered in the heart, in the years to come, sometimes unconsciously, they will suddenly understand some of them.

Regarding the treatment of knowledge, learning and applying these, according to Han Cheng’s own experience, he first had to work hard, eat these things in a spirit similar to rote memorization, and then live on the basis of firmly remembering. Learn to use it~www.wuxiahere.com~ Otherwise, if you don't even know some basic foundation, how can you learn to use it?

Of course, this is only for people with ordinary qualifications. For people who understand things like stones very quickly, and sometimes they can infer other things by the way, such things simply don't exist.

However, for the later generations when they went to school, they were obviously apt to be ordinary people, and they were very particular about learning and using. Then when they heard the hard work, they would be very contemptuous. When they came to the sentence, they would only memorize it by rote, and then later, it would be a mess. People, Han Cheng can only sniffle.

Han Cheng thinks it makes sense for a stupid person to use a stupid method as long as there is a large turtle.

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

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