Live broadcast: Ancient people accompany me to make up lessons

Nezha’s cartoons are light-hearted and enjoyable, suitable for all ages; TV series that only aired two episodes are not that bitter and hateful; various documentaries have grand and detailed narratives.

Only this movie tonight, no one can laugh after watching it.

Children who cannot understand can also feel the heaviness of this film and the lives of the people in the film through the sad music.

Those who looked at it ignorantly, half-understood, or even fully understood could not raise the corners of their mouths.

Too many people feel inexplicable sadness when they see that hard-working young man end up like that.

In the beginning, he was clearly such a hard-working and honest person who relied on his own strength to make a living. Why did he not make his life better, but instead became so depressed?

Fan Peng, a farmer from Wuzhou, saw the movie that the anchor promised to show him, but after watching it, his heart felt empty. He seemed to have a lot to say, but nothing could be said.

There are also some people who never forget the words of the old coachman.

‘We sell our sweat, our women, our meat. ’

The old man who said this was undoubtedly the lowest common man.

The custom industry has indeed existed since ancient times, but during the Taiping years, common people living in the imperial city and girls from ordinary families had no reason to engage in this kind of industry.

Mr. Cao was arrested for his radical ideas, spies were everywhere, the tyrannical army, the shabby courtyards and the beautiful foreign hospitals...

What happened in that year? Why was it so chaotic?

[The composition took 40 minutes to finish, and Xiaoxiao himself started reading it later.

She had only read part of the original work, and she had read it in junior high school. She had no impression of it, so when Fan Peng wanted her to talk about it that day, she couldn't do it at all.

Now in high school, when I watch the movie adapted from this book, I feel much better than in junior high school, but I am still within the scope of minors protected by the family, and the feelings of people in other dynasties are very different.

Taking a sip of water to relieve her congestion, she began to pump the lucky spectator.

Lucky viewer No. 1, Gu Qu, is a craftsman in the Young Mansion. He has recently learned to build various machines with the Mo family. In the past few days, he has also made a sowing machine very quickly, but there is no way to make it work. Move with less effort.

He didn't expect to be drawn so late at night, so he quickly discussed the problem to see if there was a solution.

[I couldn’t see his picture. Even if I saw it, I wasn’t a mechanical major. I thought for a moment and searched for the words ‘ancient agricultural machinery’ to see if it could be of any help to them.

"I don't know about the columbine. You can read the information yourself. However, the wind mill, a similar hand-operated threshing machine, is still used in some places.

I almost forgot, there is also Quyuanli, I’ll look for it..."]

One sows, one harvests, and finally the plowing is indeed very useful.

Gu Qu was extremely happy. He didn't expect to have such a harvest at night. After thanking him, he quickly brought the wood chips and carving knife and wrote down these two really useful things.

The information introducing the columbine also details how to use it. Although it still needs to be paired with cows and people, the efficiency improvement is tangible after all.

When Liu Che and Zhao Guo saw themselves in the materials, they had a subtle feeling of copying their own homework.

Well, today is a day to thank Da Qin, and by the way, I also want to thank Datang. That Qu Yuan Li looks very useful.

Liu Che didn't expect that there was something of his own in this. He wanted to come to the world of anchors and he also had a keen eye for pearls and fell in love with Zhao Guo. Although Zhao Guo had only been here a few days and everything was in its infancy, wasn't it ready? The result!

Although I am currently busy with breeding work and have not invented this thing at all, nor have I implemented the Shirota method, but thanks to myself in the anchor world, the energy saved after copying homework can be allocated to breeding.

Just looking at those ancient agricultural tools, neatly placed in those indoor spaces for people to visit, he felt a little sad for these tools.

Then I thought about it. Before I came to Han, I didn’t know how many farm tools were obsolete. I should be thankful that agriculture is advancing with the times, making farming less and less difficult.

Even though these tools existed in the Western Han Dynasty, just like oil pressing and brewing, only a few people knew about them throughout the dynasties.

We don’t know about, have never seen, or have the ability to obtain these tools for small farming families who have little farmland at home or rent farmland. Some villages do have a threshing machine, which can be carried out during harvest time for everyone to use together.

Some craftsmen with ideas quickly wrote down the drawings. Even if they couldn't make them and sell them, they could still see if there was room for improvement.

People in the Tang Dynasty also had that familiar feeling when they looked at Qu Yuuli in later generations.

Isn't this the Jiangdong plow we are using!

The plow frame has become smaller and lighter, which indeed makes it more flexible and labor-saving to operate. Judging from the evaluation of later generations, they are still praising us working people of the Tang Dynasty.

During the Ming and Qing Dynasties, some people who did use such plows and threshing machines did not expect that the tools they were accustomed to had such a long history.

Although there are some changes from the original one above, the principle remains the same and everyone is still using it for so many years.

Some people also think that this tool has not changed much before and now, and it has indeed reached its limit in terms of manpower. If it goes further, it will only be anchors and other big guys who can move on their own?

Lucky viewer No. 2, Song Liang, is also from the Shaofu. He also knows Gu Qu and is a colleague with him. However, Gu Qu was assigned to the Mo family and he was assigned to the Yin Yang family to study how to grind smoother lenses. .

The anchor previously gave a method for burning glass, and now there are two more methods in the burning experiment. They can only have the luxury of using crystals to grind it.

3. Han: Wei Jian was also a member of Taishi Ling of the Western Han Dynasty, and was a colleague of Luo Xiahong.

Now that the anchor has refuted the rumors, their stargazing is mainly responsible for the astronomical calendar. There is no need to worry about the impact of other celestial phenomena on the DPRK. He himself has begun to have more time to study the anchor's geography.

He was very interested in some of the things in those questions, such as the subtropical high pressure.

["This is going to take some time. Let me see if I can make it simpler for you."

Pull out the global atmospheric circulation diagram in the textbook and show them the definitions in the textbook.

"It is formed by three circulations of the global atmosphere, and there is no clear limit on what latitude it is.

Because the sun radiates strongly in the equatorial region, the geostrophic deflection force will continuously deflect the rising airflow here...

The air pressure belt and wind belt will move south or north according to seasonal changes. In our country, the subtropical high is around 30 degrees. This is the atmospheric circulation that has the greatest impact on us. Its direction every year determines the direction of precipitation in our country..."]

Supervisor Wei, who quickly drew a picture, thought of the monsoon that the anchor had mentioned before.

“In summer, high pressure forms in the Pacific Ocean in the Northern Hemisphere and low pressure forms in Eurasia, which is why the southeast monsoon occurs.

From this point of view, geography is also a comprehensive subject. Just talking about the wind blowing from the sea is not enough, it also has a great relationship with the rotation of the earth itself..."

In addition to the anchor's explanations, there are also pictures from the textbook and pictures she tried to draw herself.

Li Chunfeng took notes and figured out: from spring to summer, the east-west belt of subtropical high pressure slowly advances northward, so the rainy season is to the south of this belt. As the high pressure continues to move north, the rainy season moves northward. Advance.

If it doesn’t advance on time, is it due to external influences?

Regarding the weather, Liu Che, who was also listening carefully to the lecture, felt very uncomfortable.

"So the sooner or later the rain comes, and the amount of rain, not only depends on the monsoon, but also depends on the movement of the subtropical high, because it is not fixed every year.

For this, it also depends on the intersection of the warm air over the sea brought by the subtropical high and the cold air from the north. "

As an emperor who had to deal with various natural disasters every two years, his dream of having normal weather every year was shattered. These things simply ignored people's requests.

The previous video about Maizi was not outrageous at all.

This capricious climate is suitable for the growth of crops that humans cannot live without, but it is not necessarily suitable for human life.

What's even more terrible is that this subtropical high is just an abbreviation. The one that affects them the most is the Western Pacific subtropical high, and there are other subtropical highs. What if these things that are beyond human control do not behave according to common sense and accidents often occur?

Looking at that atmospheric circulation map, some people who like to think too much can't stop brainstorming. The more they think about it, the more they feel that the earth is really full of crises, and there are disasters everywhere that cannot be avoided.

Danger, too dangerous, host, when will your future generations immigrate to alien planets? Will there be no such dangerous things on the outer planets?

Liu Yong of the Western Han Dynasty was a farmer. Because this was related to rainfall, he listened very seriously.

He asked: "So the rain every summer depends on this sub-high to drive the monsoon?"

["Well, it is indeed the main influence of it.

It's winter, and the cold air from the north is the strongest, forcing the subtropical high to withdraw from the East Asian continent.

In late spring and early summer, the cold air from the north retreats northward, and the subtropical high begins to move northward. It meets the cold air from the north in central China. The warm and moist air flow converges, the temperature drops, the relative humidity rises, and clouds and rain appear.

In summer, the subtropical high continues to move northward, and its northernmost point reaches the Yanshan-Taihang Mountains to the area north of the Qinling Mountains, making it rainy in North China and the eastern part of northwest China. "

As she spoke, she found various air pressure and precipitation maps for everyone to see. 】

Cao Ling of the Eastern Han Dynasty had an idea, "Since the principles of weather are so clear, can we artificially intervene in these airflows and let them go to places where water and rain are scarce?"

As soon as her question came out, many people also thought so.

Since it is the intersection of cold air and warm and humid air that causes rain, are there any other ways to intervene?

["Theoretically it is indeed possible, but a lot of experiments are needed before we can intervene in the weather in the direction we want."

Every year during extreme weather, this topic will be brought up for discussion among students. Everyone has all kinds of fantastic ideas, but unfortunately, in the end they find that their ideas are too simple.

"The weather system is a complex and subtle global system. If we try to intervene by human means, the results may not be certain, and the results may not be what we want.

Moreover, intervention requires a lot of research and testing, and the money spent in this process is sky-high. If there are any bad effects after failure, you will need to bear various international responsibilities..."

Scientists have proposed throwing hydrogen bombs into typhoons very early on, but this kind of test is really difficult to do.

After all, with the surrounding countries, it’s hard to say what will happen in the end. 】

Many people probably understand.

Even if this kind of research sounds good, you can still try it, but in practice it is just not cost-effective.

The total cost of various experiments is higher than the final disaster relief effort.

And the most fearful thing is that if you interfere in one item, it will trigger a series of uncontrollable consequences, and the gain outweighs the loss.

Ma Ji of the Eastern Han Dynasty was an agricultural official. Recently, the imperial court paid special attention to farming and mulberry farming. Officials like them also had to start learning a lot.

He is not young and has seen too many things over the years. The most common ones are the helpless and crying faces of farmers during droughts and floods.

From the bottom of his heart, he hoped that there would be something that could change the weather, so that it would rain when it should rain, so that farmers no longer had to be so desperate and had to pray to God for food.

"Anchor, have you tried changing the weather? Is it really not possible?"

["Our country does not have one. What is known so far is that in the 50s, Aramco launched the 'Hurry Up Plan' that lasted for 21 years.

‘Project Hurricane’ heats the air and causes the airflow to rise to form a new airflow. New airflow formed through human intervention may interfere with the entire typhoon system.

In the 21 years since Project Hurricane was implemented, scientists have tracked more than 15 hurricanes and conducted experiments on four hurricanes.

Silver iodide was dispersed during multiple experiments to dissipate its energy, but the experimental data obtained were very unreliable.

In an experiment, it was found that the maximum wind speed of Hurricane Debbie weakened by about 30%. This is similar to the natural attenuation of hurricanes and is difficult to attribute to artificial influence.

So the experiment was stopped. "

Xiaoxiao stopped and did not mention the various conjectures of other scientists.

For example, hydrogen bombs are dropped into typhoons, airplanes drop charcoal into hurricanes, and dozens of tons of biodegradable oil are scattered on the ocean surface. 】

People who have always been interested in paying attention to the international situation in later generations frowned: Why is it that Ami again?

This Ami has appeared repeatedly in various news and test papers. It has it in aviation, it has it in war, and it also has it in this kind of meteorological experiment, which is expensive no matter how you look at it.

Liu Che made up his mind that if he got hit next time, he would definitely ask this Ami.
