I am a primitive

Stone didn't know what to say for a while.

At the right time, Han Cheng turned the fruit that served as a globe in his hand.

"Yes, it's because when turning from west to east, the easternmost side of a place is first illuminated by the sun, and when the sun disappears last, it disappears from the west side of that place..."

After Shitou thought for a while, he spoke again, with some doubts.

"Great!"

After Shitou said these words, Han Cheng put the fruit in his hand on the table, gave Shishi two thumbs up, and expressed his highest appreciation for Shitou's words.

Even though Han Cheng made a reminder, Shi Shi could still be worthy of Han Cheng's praise for being able to say such a thing!

-------------Chapter Dividing Line---------------

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! It's because the sun can shine at noon, but it can't shine at night. This is the same as we sit around the fire to warm up. The side that is heated by the fire is warm, and the side that is not heated 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.
