Xiude Fang, the courtyard in front of the main hall of the Academy of Sciences, in order not to be slapped in the face, Li Chunfeng also asked in advance, "Bachelor Li also knows astronomy?" ”

Li Zhong shook his head, astronomy is too complicated for him, and he knows some basic common sense that ordinary people know, like if you ask him where Vega is, and where does it usually appear in the sky, then he can be said to be unable to answer a word.

But this can't be helped, at the level of the next life, if you want to see the stars at night, it depends on whether the environment allows it.

"Since Master Li doesn't understand astronomy, then Master Li, aren't you messing around?"

"But I think it's reasonable for me to do that."

"How reasonable?"

"You see, isn't it very reasonable for the sun to be in the middle."

"Nope! The sun is running above the armillary sky, has Master Li ever heard of Zhang Heng's armillary sky? ”

"You mean the one who says it's like a chicken, right?"

"That's right, this is it."

"But I don't like his explanation, I think the sun should be in the middle, and then all the planets revolve around the sun."

"Where is the land?"

"Right here."

"How?"

"Right here, it's a ball."

"How could the ground be a ball."

"How can't the ground be a ball?"

……

The everybody else had their hands crossed, and you see, they said, it's going to be debated.

But to be honest, although their dean is outrageous, they still prefer to believe their dean.

Because what their dean says, there is a charm that can make people blindly believe in him.

Of course!

This is not to say that their rationality feels that their dean is right this time, but that no matter whether the dean is right or wrong, they are willing to stand on the same side as their dean.

"If it's a ball, how can the man stand on it?"

"Just stand up."

"The earth is flat."

"Nope! The earth is crooked. ”

"What do you have to prove it?"

Li Chong wanted to say that he was standing on a high mountain, but there were too few mountains that could fit this situation.

Really!

Let's talk about hot air balloons. But none of them have made it yet.

He said, "If you stand high enough and look down, you will see that the earth actually has an arc, like this. ”

However, this did not convince Li Chunfeng.

Afterwards......

Li Chong wanted to say that if you have ever been out to sea, you will find that in the distance, you will see the mast of the ship first, and then the hull of the ship.

But......

Doesn't that mean that you have been to sea? This is even more inexplicable, and at this distance, you must use a telescope, otherwise, who can have such good eyesight?

Moreover, others can find out that he has never been to sea at all, and as for reading from books, may I ask, what books do you read?

Simply......

Li Chong didn't dwell too much with him on this issue.

"How tall do you want to be?"

Li Chong replied while thinking: "Probably, it has to be tens of thousands of zhang high." ”

What Li Bai wrote, it was just a flying stream of 3,000 feet, and he was called an immortal, and Li Chong's mouth was tens of thousands of zhang, and those tens of thousands of zhang high are people who can go?

Although Li Chunfeng still doesn't know Li Bai now, it is impossible to know Li Bai in the future.

But one thing is already certain, these are just Mr. Li's own speculations.

Mr. Li certainly hasn't gone up to it himself.

"The earth is too big to fly a little higher, and it's impossible to see at all. If you can get from the moon, then the earth is completely round. ”

At this time, someone seemed to think that the water was not muddy enough, and asked, "Where is this moon?" ”

As soon as these words came out, it was like a calm pool, and suddenly someone threw a small pebble into it, and everyone unconsciously looked at each other and glared at him. Then, his eyes fell back on Li Chong.

Li Chong said: "This is not simple, the moon revolves around the earth. ”

It's getting a little complicated at first.

Everyone looked at the picture on the ground and thought about it.

"Then if that's the case, how can there be a sunrise and a moonset?"

Someone asked again.

"If it's a ball."

He muttered.

A man next to him patted him on the back of the head.

"Are you stupid, didn't you say this is turning?"

"How?"

"Rotation!" Li Chongdao, "The earth revolves around the sun, and the earth itself will rotate, the cycle of revolution is one year, and the cycle of rotation is twelve hours. ”

"Yes...... Isn't the sun shining on it all the time? Could it be that the sun is also turning? And turned to the back, it's the night? ”

All I can say is......

It's not like everyone's head is first-class smart.

But even if he was wrong, it was a good attempt.

Li Chunfeng said: "Master Li thinks that the sun is a fireball? ”

"Isn't it? Since ancient times, there has been no one who has not thought that the sun is a fireball. Moreover, the moon is also a ball. So, I think, everything else should be a ball as well. Li Chongdao.

"Isn't that a cake for the moon?"

Someone else forked the way.

"Superficial, that's because it's so far away, your reason is blinded by what your eyes see. Sometimes, seeing is not necessarily believing. ”

At this time, Li Chunfeng had already vaguely touched something. But I'm still a little confused about how to explain that the sun I see every morning always rises in the east and sets in the west. It seems that I can't find the doorway yet.

I saw that his brows were deeply locked, and at this moment, he no longer completely rejected Li Chong's views.

Instead, try to get deeper little by little. Because if you don't even understand it, and you criticize it directly, then you won't even find a basis for wanting to reprimand the other party for being wrong.

He was soon writing and drawing on the ground.

He drew two balls and made tangents to the two balls.

But the question is......

It's just a loss, it's a loss, but he never seems to be able to enter that door.

Li Zhong whispered to him in his ear: "The earth is rotating from west to east. The earth is like a chopstick that goes along the two recesses of the apple. Then, as long as you turn the chopsticks vertically, the whole apple will also rotate. Fireballs can only reach half of the Earth, so a day is always half day and half night. ”

Li Chunfeng was teased by him like this, and also said: "The actual time of nightfall with the change of seasons that year is not the same, how can this be explained?" Moreover, even if there are twelve hours in a day, not all of them are six hours of day and six hours of night. ”

Li Chong: "That's because it's not a serious vertical rotation, but an oblique rotation." ”

Then Li Zhong drew him a picture of spring, summer, autumn and winter caused by the intersection of yellow and red, and said: "You said that in a day, twelve hours, not all six hours are day, and six hours are night, which is very good, in fact, this is also a piece of evidence that can determine where we are on the ball." We, I mean Datang, are pretty much in this position! Eh, you go get an apple and a chopstick. ”
