Live broadcast: Ancient people accompany me to make up lessons

The eleventh lucky viewer, Shen Changgui, was a carpenter from the Wu Zhou Dynasty. He always remembered the small, fast-turning thing that the doctor held in his hand when he removed the cast for the anchor.

It seems to have saw teeth, a curved saw that can rotate by itself. It can cut plaster, so it should also be able to cut wood, but why doesn't it cut off the anchor's hand?

This question is based on current affairs. Shen Changgui is not the only one who wants to know. There are many anchors and people who are curious.

Looking at the explanation video found by the anchor, some people still can't understand it.

"Why is it that the saw up there can leave marks even on steel, but it can't hurt anyone?"

Someone who understood it explained to him: "Look at the circular saw. It's all marked. It doesn't rotate. It just moves left and right twice. The meat also moves with it. Of course it can't be damaged. It's all on it." I said it, it’s called a reciprocating saw.”

"But if we pull the saw repeatedly, can't it also cut off someone's hand?"

The man patiently explained: "The saw is made by people using force. Look at this saw, the force and speed of its rotation are fixed. No one is as powerful as a human..."

When explaining the principle in the video, there is also a split structure. Although we will definitely not be able to build an eccentric motor for the time being, the gears and cylindrical structure inside make the craftsmen happy.

After knowing the scientific principles and seeing its movement pattern, even if they can't make it automatically turn on the electricity, they can still learn it first, and it will always be useful in the future.

In the early Northern Song Dynasty, Zhou Yuying was a skilled embroiderer. After her husband died, she ran a small silk and satin shop with her children.

She doesn't understand the important matters of family and country, but she understands the embroidery business.

She reported the address of her silk and satin shop and posted her most proud embroidery on the sky for the anchor to appreciate.

The other businessmen thought for a moment that this Zhou Yuying was really good at advertising. Now, in addition to Da Song, even Da Qin people knew about her shop and craftsmanship.

In the Qin and Han Dynasties, when embroidery technology was not as developed as that of later generations, Zhou Yuying's exquisite embroidery really opened everyone's eyes.

Embroiderers working in the clothing industry opened their eyes wide, trying to see clearly what the techniques and patterns of embroidery would be like in later generations.

[Although it was used as an advertisement, the product itself was indeed excellent enough. After seeing it, Xiao Xiao could only nod silently and praise it for being awesome. 】

When she praised her, Zhou Yuying became happy. With the anchor's marquee publicity and her own words of praise, she had become Zhou Yuniang's brand in the Song Dynasty.

Other equally skilled male and female embroiderers were not convinced. Zhou Yuying was indeed lucky this week and her embroidery skills were not bad, but the anchor had never seen them before.

Whenever they are lucky enough to win, they must let the anchor see what more powerful embroidery skills look like!

As the third member of the Song Dynasty who was lucky enough to be on the list again, Su Song did not receive any rule from the officials at home, so he knew that there was no need to ask the anchor about military and state affairs. This was to allow him to express himself freely.

So Su Song thought about it for a long time and decided to ask the anchor about weather observation.

"Anchor, I don't know how you measure the temperature and wind direction. Is there any simple way that can be observed in every county?"

Natural disasters are still more important. Experienced farmers can predict whether it will be sunny or rainy the next day or the same day through basic celestial phenomena, but more accurate temperature and wind direction measurements are still very technically difficult for them.

[“Weather stations use thermometers to measure air temperature.

Common thermometers include mercury thermometers, alcohol thermometers and electronic thermometers. I won’t tell you about the electronic ones.

Mercury thermometers are usually used to measure outdoor temperatures, while alcohol thermometers are suitable for measuring lower temperatures... I'll go and give them to you to use."

After introducing the principle of a mercury thermometer, Xiaoxiao stepped out of the study room in his slippers and went to the medicine box to find a small household mercury thermometer.

Thanks to always having this at home, they didn’t have to rush to buy forehead thermometer guns during the epidemic, and now they have a habit of keeping basic medicines on hand.

Shaking the thermometer, she turned the thermometer back and forth a few more times to allow the system to zoom in to ensure that myopic eyes could clearly see the scale on it, and then tucked it into her armpit.

Zhuge Haoran was watching TV in the living room when his sight was suddenly blocked. His eyelids twitched: "What's wrong? You suddenly took your temperature. Do you have a cold?"

Xiaoxiao shook his head and quickly explained that he was just coming out to take a look. By the way, he asked his father how to make such a large mercury thermometer at the weather station. 】

Su Song listened carefully to the anchor's father's introduction and nodded while remembering.

Mercury or alcohol are materials that are relatively easy for them to obtain, and they are not that expensive. Even though each county has some that are difficult to obtain, it can still be obtained in important cities.

The last thing is the scale unit. It is best to be consistent with the temperature unit on the anchor's side, so that it will be easier to pay attention to what the anchor says in the future.

Initially, many people were speechless when they saw Zhuge Haoran lying there.

Because his unreliable image in everyone's mind is too deeply rooted in people's hearts. Seeing him lying there watching TV with a mobile phone in his hand and various snacks in front of him. Compared with the anchor's studiousness, this dad is really impressive. I feel a little owed.

Forget about a man who is in his 70s or 80s, but even his own mother is so energetic and enthusiastic about her work. In comparison, it seems that Zhuge Haoran seems to have nothing to do at home every day.

Now that he talks about some things in a clear and logical manner, many people have changed their minds.

The anchor’s father is quite talented.

Seeing the anchor's father watching TV, Zhu Houcong felt a chill in his heart, especially when he saw the TV series about his Ming Dynasty, his heart was pounding even more.

In the palace with gorgeous curtains hanging down, the actor playing the role of 'Jia Jing' was beating the chime and telling fortunes based on the lingering sound as he stepped forward. He looked quite elegant, but he didn't look like a serious emperor.

Zhu Yuanzhang and Zhu Di became very angry. Even though they knew it was made up, they became angry when they saw the people on TV showing how they were not doing their jobs properly.

Zhu Houcong was convinced. Could the anchor's father watch some other TV instead of just staring at this every day?

But having said that, the actor's appearance is indeed good, his beard is beautifully trimmed, and his demi-fairy demeanor is quite good. He can do the same in the future.

Ahem, he was talking about the style, nothing else, don’t get me wrong.

["Yeah, I know the mercury thermometer, but what about the wind? The wind direction is easy to say, you can have a wind vane. If there is no electronic equipment, how should the wind strength be measured?"

Zhuge Haoran paused the TV first, found a rotary cup anemometer on his phone and introduced the principle to her.

"...Speaking of which, Li Chunfeng of the Tang Dynasty was the first ancient scientist in the world to classify wind.

He also has a "three-legged chicken wind indicator" designed by himself to observe the wind and set a wind level of one to eight according to the changes and damage caused by the wind to the trees. "

Seeing his daughter's dazed look, he laughed to himself: "It's so scientific. Is it so scientific that you are dumbfounded?"

Xiaoxiao: "Modern wind measurement seems to set the wind as 0-12 based on the propulsion effect of the wind on the sail..."

Is Li Chunfeng, who asked her just a few minutes ago, actually an ancient scientist? She only remembered the story between him and Yuan Tiangang.

Find out Li Chunfeng's information and show it to her. In addition to being the first person in the world to classify winds, he is also the first person to accurately predict a total solar eclipse, the first person to discover that comets do not emit light, and the first person to invent astronomical observers. Man, the first person to write a weather book...]

"Astronomer, mathematician, Yi scholar... Darling, has Li Chunfeng actually achieved so many achievements?"

Ordinary people who don’t have many ways to study or read books, know that most of these names are either operas or teahouse storytellers. The Li Chunfeng in those stories is not the same person at all as the one in the anchor’s father’s mobile phone!

I knew that Li Chunfeng was powerful, but I didn't expect that he could be so powerful and wipe the sweat of the Zhenguan monarchs and ministers. Well, I entrusted him with the mathematics and geography of the new school. I really found the right person.

[Xiao Xiao lowered his head, feeling a little ashamed of the impression he had taken for granted.

"You also said it was a sail. Once you hear it, you can't leave those countries with great voyages."

Zhuge Haoran patted her head: "We also had various sciences in ancient times, and we used to be very open and tolerant.

As for why we think of it as feudal superstition when we think of the ancients, and why we always think that science is a foreign word... we have to ask about the Ming and Qing Dynasties. ”]

People from the Ming and Qing Dynasties: Wait, why is it us again? Why did we become the ones who were scolded after the Tang Dynasty?

The anchor's father's words contained too much information, and even those with a sly mind would feel that something was wrong even if they thought about it.

Generally speaking, the past is also part of the present. When they look at their ancestors, they usually rarely think that they will do anything bad. How come the anchor's father said that their descendants look at the ancients and think they are feudal and superstitious?

They now also know what science is, which is the method and means of researching and exploring the world. The anchor also said in the past that alchemists are the earliest chemists, which shows that although they have different terms, they are still on the road of exploration.

Why does it mean that when it comes to ‘science’, it’s all from foreign countries?

Li Chunfeng, who has not yet written the two books "Yi Si Zhan" and "Guan Xiang Wan Zhan", is not happy at all.

If he proposed this method of grading wind, it doesn't matter if later generations don't use his method. Technology has improved and they have more accurate methods, which is a good thing.

But when it comes to this, all the anchors think of is the outside world, which is very problematic.

It shows that it is not mentioned at all in their books.

Previously, the anchor exaggerated that Tang You said "open and inclusive", but now the anchor's father also says the same, which corresponds to the Central Plains after their Tang Dynasty, which is completely different.

Think about the things the anchor mentioned about the Ming and Qing dynasties, such as burial, ritual observance, foot binding, Neo-Confucianism, and the study of psychology...

Well, both of these dynasties cannot be said to be open and inclusive.

Li Chunfeng also remembers that when he talked about the Great Navigation before, he mentioned the Ming Dynasty and the Qing Dynasty.

Su Song himself is an all-rounder, knowing everything and being interested in everything. So far, he is one of the few people who can keep up with the anchor's classes.

As a person who can be a prime minister, he sees and thinks about more things, so his frown never relaxes.

Like Shen Kuo, he and Shen Kuo both had personal interests. In addition, he had a wealthy family background and had enough ability and resources to learn other things.

But others with limited abilities will only focus on the imperial examination, because there is no more important career than being an official.

In the past, everyone thought that everything else was just trails and nothing important; after watching the live broadcast for so many days, I found that these usually inconspicuous trails, when combined, can be traced back to their roots, which is science.

As for science, it can create the life world of anchors. The most important thing is that it can make everyone in the world have enough to eat.

In the eyes of most of the anchors, thinking of their ancestors is like feudal superstition, and mentioning foreign countries is like science.

That undoubtedly shows that when they were closest to the anchors, that dynasty had no science, or left little science behind, or even all of it was foreign.

There is nothing they can do if future generations fail to live up to expectations, but in the Song Dynasty alone, there were quite a lot of things recorded that could be considered scientific. How come future generations don’t know about it?

Was it lost during the war, or was it given up by later dynasties because it didn't care at all?

Su Song flashed through the previous history paper again in his mind and sighed. No wonder it said that Western learning spread to the East.

Gradually, not only ideological culture but also these sciences that existed before were introduced.

Thinking of this, the scholar-bureaucrats, who had always been proud of being a country of etiquette, found it somewhat unacceptable.

Why do they have such an image in future generations?

[After six or seven minutes, Xiaoxiao took out the thermometer, adjusted the angle, and carefully displayed the scale where the mercury reached.

Zhuge Haoran also came over to take a look, "Okay, 37.1, the temperature is normal, go back."

After placing the thermometer, I returned to the study. Before calling the number, I talked about the volatility and toxicity of mercury. I reminded everyone not to touch it with hands when making it, and to hold their breath, cover their noses with something, etc. Protective measures. 】

Some people who are interested in making alchemy and whose ingredients are indispensable for cinnabar are beginning to get nervous.

The anchor's thermometer only had a small amount of mercury, and she was so careful. Even the amount of elixir they put in... hiss, thinking about it, she felt like she didn't live enough.

Shen Jin, who is also from the Zhe Zong Dynasty, feels that he still needs to explain something.

For example, although they also had foot binding in the Song Dynasty, it was only on the tip of the toes to make the feet look better, and it did not affect the women's normal walking. It was not as perverted as the foot binding in the Ming and Qing Dynasties. This problem really does not belong to them.

I finally made myself forget those ancient people with small feet: ...Thank you, I remembered it again, and I couldn’t sleep after waiting so late at night.

Zhao Kuangyin covered his face, feeling that his face had been completely humiliated by Zhao Guangyi's descendants. If we don't contact you, don't explain. If you explain, you'll take the blame. You're just pestering me!

Look at the host's expression, I feel like she is so disgusted that she is going to vomit.

[Xiao Xiao, who thought he was going to prove something to himself, was really disgusted.

“So don’t you still think that women’s small feet are beautiful, so you let women bind their feet to make their feet smaller to cater to your aesthetics?

They are all perverted aesthetics obtained by mutilating women's bodies. I am not interested in understanding them. Your turn is the fifteenth lucky viewer. ”]

Many people nodded in unison. No matter whether you wore a broken bone or a sharp one, the pictures in their minds were all those scary photos. There was no difference.

They also find this kind of aesthetic perverted, unable to understand, unable to appreciate, and have no interest in understanding it at all.

What kind of explanation is there? If you don't bother me enough to do it, you just haven't done it. You even come here to explain this to the anchor. This person from Song Dynasty is really annoying.

Zhao Xu felt very embarrassed. Look at what his minister Su Song asked, and look at what Shen Jin said. Did he think he was rectifying the name of the Song Dynasty?

Just remember one more name in the notebook, and forget about the imperial examination.

After memorizing it, others became even more angry. How could such a fool be chosen? The system is too fair and random!
