Live broadcast: Ancient people accompany me to make up lessons

After finishing the small paper, the hour was almost up, and she quickly started correcting the answers.

Looking at the red pens ticking and crossing, generally speaking, there were more correct answers and fewer wrong ones, and many people also started correcting the answers.

Kangxi waited until he got to the question about the direct sun point of the Tropic of Cancer. Sure enough, the anchor was wrong and his answer was correct. His depressed mood had improved a lot in the past two days. However, the color is precious. When he saw the anchor holding a red pen here to change the question, even if he knew it was not cinnabar, he could not help but think of the royal pen and vermilion, and his good mood turned bad again.

In addition to the officials who are recording this knowledge, people who can understand a little bit are also paying close attention to the answers and recording the answers with the anchor's red pen.

In some dynasty centers, everyone is eagerly looking forward to changing to the non-choice questions at the end, wondering how to answer those knowledge related to people's livelihood. The anchor has written it down, but they think one of it is too general, and the other is that they still don’t understand the meaning of some professional terms.

But when the anchor finished correcting the answers, they found that the anchor had written something less, and they still didn't understand what was written.

The ecological environment, industrial pollution, recycling, high-tech... They don't understand any of these words.

Ah, I feel like I have more and more things to ask the host...

[When Xiao Xiaochao finished the paper after 10 points, the system quickly reminded her that it was time to draw a barrage.

"Host, it's been 10 minutes. It's time to fire the barrage."

He put the papers away in the folder of the finished papers and took a sip of water.

"Sorry, I'm ten minutes late. We're going to draw the lucky audience right now. It's still the same, ten people will be drawn, and the countdown will begin."]

The audience who didn't know what the lottery was for the first time last time, this time they all sat upright or stood upright, looking at the sky. They learned the concept of metaphysics without any teacher, and while thinking about "the middle of the middle", Clicked the button to participate in the lottery in front of me.

A huge roll of names, and in a few seconds, ten jealous lucky viewers appeared again.

1. Qin Dynasty: Mo Weishang (fictional)

2. Qin Dynasty: Bi Gu (fictional)

3. Han Dynasty: Luo Xia Hong

4. Han Dynasty: Zhang Heng

5. Tang Dynasty: Li Chunfeng

6. Tang Dynasty: Zhang Sui

7. Tang Dynasty: Li Chengqian

8. Song Dynasty: Shen Kuo

9. Ming Dynasty: Wu Chengen

10. Ming Dynasty: Wang Shouren

Of the two lesser-known names of the Qin Dynasty, the first one, as soon as they saw the word 'Mo' in front of them, the courtiers of the Qin Dynasty basically knew that they were related to the Mohist family, but they were not yet sure which sect they belonged to; the second The two of them were not well-known, but both central ministers and local officials immediately sent people to search for these two people.

Ying Zheng made a decision in his heart. Although a lot of things had happened to them in Da Qin and the Xiangli Mo family, the changes brought about by the sky were too great. He was in urgent need of all kinds of talents and his selection conditions could be relaxed appropriately.

"Li Si, the lineage of the Mo family in Xiangli came to Xianyang."

Li Si took the order. He knew that the appearance of Tianmu had stirred up a huge stir in the empire that had become increasingly stable after reunification. Being able to recognize the situation very well, he wrote a letter to his junior brother Zhang Cang in the next court yesterday, urging him to come to Xianyang.

The Legalists can't just have him in charge of the facade, they must have other talents.

The people of the Qing Dynasty who did not have a lucky audience this time could only wait for other ancient people to ask questions. Among them, the names they were most familiar with, besides Li Chunfeng, were Wu Chengen and Wang Shouren.

Although it was a bit regretful, everyone was very excited to see the author of "Journey to the West" and Mr. Yangming so close.

But was Shen Kuo of the Song Dynasty so lucky? Why was he on the list twice?

[Xiao Xiao starts calling as usual: "Lucky Audience No. 1, please speak."]

In the countryside of Daqin, everyone from the Mo family gathered together wearing straw sandals and working in the morning while watching the anchor study. A young man surrounded by his brothers was also very excited.

He knew that his brothers and sisters all had questions they wanted to ask, and so did his master. But what he wanted to say, everyone said it was his destiny. Don't waste it, just ask the questions you like.

The young man nodded with tears in his eyes, excited and moved. When he heard the anchor calling him, he hurriedly bowed to the sky and asked his question.

"May I ask the host, what are celestial bodies, the Milky Way, extragalactic galaxies, planets and the eight major planets?"

Drawing on the experience of Zhu Houzhao last time, everyone found that one sentence can also ask one more question. Too curious about these astronomical knowledge, Mo Weishang asked them all at once.

[Celestial bodies, the Milky Way, extragalactic galaxies, planets...there are really a lot of questions.

Fortunately, Xiaoxiao chewed on the book and remembered the definitions accurately. She quickly turned on the computer and started looking for pictures.

"There are three definitions of celestial bodies. Those that are outside the earth's atmosphere, have independent orbits, and are material are celestial bodies.

Clouds are in the sky but are within the atmosphere, so they are not celestial bodies; stars are outside the atmosphere, have orbits, and are concrete substances, so they are celestial bodies. ”]

Although the Mohists are not good at astrology, they are not completely ignorant of it. The Mo family gathered together and discussed each other word by word.

"In this way, the atmosphere should have a certain size. Clouds are within this range. If they exceed this range, they are celestial bodies."

"There are other conditions that need to be met. Clouds only move when they are blown by the wind. They have no trajectory."

"Definition is a good idea, but what is the definition of trajectory?"

"Matter... Celestial bodies belong to matter, so what is matter?"

"The definition of a planet is a celestial body that has a certain mass, does not emit its own light, and orbits a star. Taking my case as an example, the land I step on is a planet, and we call it the earth."

This kind of astronomical knowledge may be a bit too much for people in backward world, so Xiaoxiao directly found a video of the movement of the solar system and played it at 0.5x speed.

The dark universe is dotted with stars, and the huge fireball in the middle emits a dazzling light.

[Xiao Xiao pointed at it and introduced: "This is a star, a luminous sphere or spherical celestial body made of plasma. Our star is called the sun."]

The fiery red sphere floated quietly in the dark night sky, illuminating everything around it.

Everyone held their breath and looked at the star quietly, looking at the sun that they looked up to every day but had never seen the full picture.

Many people looked at it and shed tears.

This is the sun, the sun that governs their food, clothing, housing and transportation...

["The sun is a star, and the planets orbiting around the star. The nearest star here has a total of eight planets. From front to back, they are Mercury, Venus, and Earth, which are the planets where we humans live, Mars, Jupiter, Saturn, Uranus, Neptune...these planets are called the eight planets.

The moon is not a planet. It does not revolve around the sun, but around the planet earth. It is the earth's only natural satellite.

Other celestial bodies, including the eight planets, are affected by the gravity of the sun and are called the solar system.

In the past, the solar system had nine planets, and there was Pluto behind Neptune. However, scientists kicked it out of the ranks of planets more than ten years ago and became dwarf planets. Now the solar system has eight planets. "

Thinking back to when he was a kid, he thought the names of the three stars at the back were so cool, and then thinking about Pluto being demoted, Xiaoxiao started to cry out for it. 】

If the stars had the Internet, I guess Pluto would post in a circle of friends: You are the ones who called me a planet and pulled me into the group chat, and you are the ones who kicked me out. Hey, humans.

The vast universe and the beautiful planets fascinate people, but apart from professionals and enthusiasts, the experience of Pluto obviously makes everyone want to communicate.

Liu Che saw Luo Xiahong, who had just been called, looking at the stars infatuatedly. He turned around and complained to Wei Qing: "This star can still be kicked out. Pluto has a spirit, so I think it will be unlucky."

Wei Qing didn't want to speak, but he couldn't help complaining about their majesty. Just now he thought the names of the stars behind them were very nice, but now he started to be disrespectful.

Zhang Heng stroked his beard while carefully looking at these stars of different sizes, some of which looked like rice grains in front of the sun. They were all old acquaintances. Even the land they live on, the planet called Earth, is small next to Saturn and Jupiter, let alone compared to the sun.

He can guess that future generations will have extremely strict standards for judging astrology, which is a good thing. He can also ask the anchor some things later, but what he is most concerned about right now is the trajectory of these planets.

Thanks to the considerate anchor, the trajectory of the planets above is displayed with a thin line, allowing professionals like them to know the trajectory of the movement at once.

["There are many celestial bodies like the solar system in the universe, and many galaxies including it form the Milky Way. We call galaxies outside the Milky Way extragalactic galaxies."

The video on the solar system ended, and there happened to be a video recommended below called "Looking at the Universe from the Earth," so Xiaoxiao showed it to them. 】

[Gentle music plays, and the camera angle rises from the snow-capped Himalayas. Gradually, the land in the distance gradually becomes smaller and curved, the blue sky also begins to turn dark, and the vast land finally turns into a blue planet. . ]

The mysterious universe has endless attraction for people, and everyone has a natural fear and curiosity about it.

Someone saw traces of water flow when the camera zoomed out, and shouted: "Yellow River! Look, that's the Yellow River!"

But the camera quickly zoomed out, the stars turned, and the water of the Yellow River disappeared.

[The blue planet rotates slowly, half of it faces the light, and the other half is pitch black and scary.

Many small rays of light appeared, and the words "artificial satellite" also appeared at the bottom of the screen. The earth surrounded by artificial satellite orbits is getting smaller and smaller, and the dazzling sun and gray moon appear.

The camera zoomed out, and the moon, lunar orbit, planets, and planetary orbits appeared one by one. The huge sun also began to become smaller, and the words "solar system" appeared.

One planet after another is connected by straight lines, and four words "Zodiac Constellation" appear under the familiar shape. ]

The supreme king is extremely small in front of the vast universe. Looking at the vast earth, it is not even the size of a grain of rice, Ying Zheng's eyes are dark.

More people, in addition to being shocked by the vastness of the universe, are identifying the stars of their own knowledge.

"Big Dipper, that's the Big Dipper!"

"Tianshu Star!"

"That's Si Ming!"

People who know these stars try to keep their eyes open and remember these stars in their minds.

[The zodiac constellations turned around and became smaller and smaller, and a star made of lines appeared, called "Human Radio Signal".

This one also slowly became smaller, the dark universe glowed with white light, and a huge white and bright barred spiral galaxy in the center appeared. This is the Milky Way.

The music starts to get louder, but it makes people's hearts become colder and quieter.

There was darkness all around the Milky Way, until it became smaller and smaller, as small as a grain of rice, and then many star groups the same size or even larger appeared.

With a point as the center, the stars eventually form a cone that opens to the left and right.

"Quasars, the farthest objects that humans can observe." ]

People who have never seen distant stars are fascinated by the vast universe, and no one is willing to blink.

The earth beneath his feet was just a speck of dust in the vast universe, and the unspeakable loneliness lingered in everyone's hearts.
