Live broadcast: Ancient people accompany me to make up lessons

Wei Yichang, a native of the Ming Dynasty, listened carefully to the lectures every day. In addition to being interested in the courses the anchor studied, he was also very interested in the technology of the future generation where the anchor came from. The one he was most interested in was undoubtedly the airplane.

"I want to ask the anchor, how are those white planes of yours made, and how do they fly at high altitudes?"

There are so many people who think that the materials of the aircraft are not good whether they are light or heavy, so how can they fly?

["Different parts of the aircraft are made of metal and various composite materials, which are very heavy. The aircraft needs to generate thrust through the engine first to continuously push itself forward."

Xiaoxiao found a structural diagram of a passenger aircraft and pointed to different parts to explain.

"Due to the structure of the wing, the air pressure below it is greater than the air pressure above it. The pressure difference between the two forms the lift of the aircraft, causing the air pressure below to drag the aircraft forward.

The faster the plane flies forward, the more aerodynamic lift the wings produce. "

Helicopter... Xiaoxiao went to find photos of large helicopters.

"The helicopter mainly relies on the propeller on the top. The blades rotate to generate lift, the propeller disc changes direction, and the tail rotor is used to change the direction of the nose..."]

Some people who originally thought that studying the atmosphere had no use other than weather forecasting were really happy.

Studying the atmosphere sounds boring, but when they study airplanes, they feel that this subject becomes magical in an instant.

Some scientists who were not very famous in ancient times lowered their heads to draw the structure of the aircraft, and then learned from the anchor to draw arrows to indicate the direction of air pressure, trying to mentally review how the air around the big thing moved when it flew up.

Helicopters that fly with propellers are relatively easy to understand, but everyone is still thinking about how to make the blades move.

They have also seen helicopters in disaster relief videos, and remember that people sit inside and control the aircraft. How do they make it possible for people to control the entire aircraft from inside the cabin?

["If you want to make it, let me see if there are any videos of making airplanes."

This kind of large-scale industrial manufacturing is still easy to find. Xiaoxiao found the video easily. Needless to say, she hasn't watched it yet. 】

Knowing that there cannot be any ancient or homemade methods for making airplanes, and seeing a bunch of covers showing various manufacturing factories, different countries, and different models, everyone can't help but wonder: This factory that appeared in the British Industrial Revolution has actually been around since then. Continue to the present?

Moreover, the name of the country and the aircraft appear on the title, and the overlap rate is almost the same. Does it mean that only these are famous, or that only these few can be built?

When the anchor clicked in, they followed the wide-angle lens and first saw the room, which was so big that the corners could not be seen. The ceiling was made of countless steels, with white lights scattered all over it. Below, there were a group of people wearing the same or different clothes, wearing The man in a hard hat was working in an unknown aircraft component.

"Does it actually cost so much to build an airplane..."

Sang Hongyang didn't know about other things, but just looking at the steel frame to build such a large factory, he calculated the cost in the current Han Dynasty, and it was a big expense.

Comparing the working people, none of them are as big as the aircraft parts they work on, and such large aircraft parts are being dragged by cars in this factory without worrying about touching the ceiling of the factory. The height is really not low.

If this factory is located in Han, can it be replaced with other materials? But in such a large place, wood and brick walls are not enough to support it...

Some are looking at the cost of construction, others are looking at the people working on it.

They are not farmers, but they are not craftsmen either. If we want to make an analogy, they may be compared with the female weavers in some Jiangnan workshops, but this is not what female workers do...

[The overall video is very fast, but the occasional flashing text and captured portraits show that this is a foreign country.

These people are all wearing the same clothes and the same hats on their heads. There are a few or even a dozen people in groups, each doing different things.

Starting from the crane lifting an empty aircraft shell, everyone has been pressed on some kind of start button, and they are doing their own things in an orderly manner. When it is over, it is the turn of the next group of people in the next link. No one is fully involved in this process. , everyone performs it according to different division of labor.

There are tools for lifting and transporting large and small things. After an aircraft is assembled according to its parts, someone will use a pipe to spray water to clean it, and then spray paint on the smooth silver metal. Finally, a large aircraft will be pulled Go outside and try flying. ]

The whole process is orderly. When the large aircraft is moving on the runway, the charm of the complete industrial product transformed from parts, although there is no unrestrained poetry and romance, still makes everyone mesmerized.

"How wonderful! How wonderful!"

The miraculous manufacturing process, as well as the dashboard that lights up instantly when touched, and the completely incomprehensible instrument panel, all allow skilled writers to record them in their minds, waiting to be written down later.

Although the process went smoothly and there was no story conflict, the storytellers also re-imagined the process in their minds and thought about how to use vivid words to inspire everyone to imagine again after the curtain ended.

There are also those professional book writers who have automatically written a story in their brains about someone destroying a factory, a righteous man saving the factory, and finally flying around the world with his family on a plane.

As for the aircraft still needing maintenance, flying requires qualification certificates, fuel is required for starting, etc., there are so many things to do with literary and artistic creation.

I made a globe two days ago and it was selling well at the carpenter's house. I listened to the children at home looking at the airplane in wonder and clamoring for it. They picked up the thing that was eating, but they couldn't make it so big and fly, just like that. Let's make a similar shape out of wood.

Some people looked at this factory and began to think about such a large factory. A large aircraft cannot be built overnight. The arrangements, personnel management, safety assurance, and post-inspection are not easy tasks. .

Lucky viewer No. 9 Bao Qiuchi asked curiously: "Anchor, besides this factory that makes airplanes, are there any other factories?"

"Yes, there are many other factories."

"We have various clothing and textile factories to wear clothes; and we have various food factories to eat and drink." She pulled the clothes on her body and pointed to the snacks and milk on the table as an example.

“There are also corresponding small factories for hair ties, there are furniture factories for tables and chairs, there are printing factories and paper factories for books, there are also manufacturing factories for mobile phones and computers...

Although we now highly value handmade and natural products, many of them are fake, claiming to be handmade or machine-made.

This kind of machine replaces manual work and can be copied and produced on a large scale. The process of mass production with high quality and efficiency is what we call industrialization. ”]

industrialization?

Then a lucky viewer from the Qing Dynasty couldn't help but ask: "Then anchor, you who have studied for so many years or have not studied at all, will you go to work in this factory after you come out?"

["Well, after all, we are the world's factory. All production lines can be found in China. Similarly, we need a large number of workers. There are about 3 manufacturing workers."

Xiaoxiao doesn't know much about this kind of thing: "My dad said that there are actually more middle-aged people in factories now, and there are fewer young people, who have not studied much. Many factories also need training, and senior talents also need training." Need to get off the production line."]

Considering the population of 140 million in later generations, this number is not small. For every dozen people there is someone working in a factory.

It is indeed impossible to feed so many people without those high-yield grains, and it is impossible to get so many people off the land without those machines.

The more I think about it, the more I realize this is a cycle.

["Okay, that's it for today's live broadcast. Let's start voting for tonight's film and television content. See you tonight, everyone."]

Before they could think about it again, the anchor waved his hand and left the broadcast. Looking at the voting channel which only lasted for five minutes, everyone quickly cast their precious votes, even if the system did not know the votes, they did not see the end of the voting until the sky disappeared. How are the votes going?

"Brother, I understand! Let these machines replace people to do dangerous and troublesome things. Use these machines to improve efficiency. Whether it is farming, blacksmithing or weaving, the efficiency is improved. With good seeds and machines for farming, everything can be done with half the effort!"

In the Mo family's stronghold in Xianyang, a middle-aged man's eyes were shining with surprise.

"Starting from the steam engine, we first created machines, and then relied on burning coal to drive the machines. It became easier to rely on these machines to plow fields and weave cloth. Then we continued to research, steam trains, steam ships, airplanes... everything became faster. stand up.

With fewer people farming, more people can do other things, study, research, and continue to improve these things..."

Take this large aircraft as an example. From the beginning of its design, sufficient scientific knowledge is required to design it.

Production also requires people and machines to work together, and even requires special personnel to watch. Even the people who make these are by no means ordinary people, and what they do also requires corresponding knowledge.

"No wonder future generations need to educate all the people."

He wiped the sweat from his head and whispered: "We in the Mo family also need to let more people be able to read and write and learn our knowledge.

Our things should not just be produced by a few of us for the use of noble people. "

Look at how many seats there are on a plane in the future, how many new planes are built, and think about the hurried flow of people at the Tianjin Airport that day. This is not something only for a few people.

The fellow student next to him added: "According to what the anchor said, it can be copied and produced on a large scale. In other words, it must be able to be made in Xianyang or Handan, so every step of our creation should be exactly the same."

"Looking at it this way, in addition to experienced craftsmen, it is indeed the set machines that can do it better..."

At Gongshu's house, Gongshu Gu felt that he couldn't wait any longer.

"Father, uncle, the emperor has issued an edict to seek talents. Pack your things today, and we will set off as a family tomorrow!"

His father looked hesitant, wondering if he was too anxious. The newly made riding suit could not be easily mass-produced.

Gong Sugu: "It's no time to think about this. Now the first to go will win the emperor's favor. We can slowly improve the horse matter. My son has other things that can be dedicated to the emperor."

He had a good chemistry class before. At that time, the anchor introduced various elements and gases. He collected all the materials and tried to make something. He was able to slowly bring a small basket to the sky.

Airplanes, which require a large amount of ores and unknown composite materials, cannot be made now, but today's things can try to enlarge the basket several times and take people to the sky. This is also a good thing that can be used in the military.

Although it is just a small concept that a basket can fly, he is confident that the emperor will be willing to see this thing become bigger and reach the sky. After all, there are still Huns on the grassland in the north.

The small Yin Yang family also packed their bags and prepared to take their disciples to Xianyang.

Although Tianmu popularizes science now, everyone must be dissatisfied with their previous theory of "using the flow and changes of yin, yang and five elements in the natural environment to explain and predict various social and natural phenomena." , but even if this is the case, we cannot let our school of thought take advantage of this opportunity.

No matter what, we can no longer allow Confucianism to dominate us without knowing it!

Besides, although the theory is now under attack, skills such as astronomy, calendar, timekeeping, and divination are indispensable for members of the Yin Yang family. In terms of mathematics, everyone is confident that they will not be far behind.

Each of them is also working hard to study geography. If they can't go to heaven, they can go down to the countryside and become the production and life guides of this large agricultural country.

Don’t say anything anymore, host, when are you going to write geography papers again? We have a student named Zhuge in our Yin Yang family. Will you send books as appropriate?

Unlike the Mohists and Confucians, the people of the Yin Yang family are quite wealthy. Each of them has some crystals. In the past few days, he has fumbled to make a small single-sided telescope based on the principle of the space telescope.

The stars are invisible, but it is okay to see things in the distance clearly. They believe that Emperor Qin will like this gift.

There were not many famous people and strategists, and a few of them met at Hangu Pass.

The two sides, who are equally good at eloquence but have different directions, greeted each other and didn't mind asking each other what they were going to do when they entered Xianyang.

Several members of the Strategist family smiled slightly. There is such a huge world outside the Qin Dynasty. There are the Xiongnu in the north, Baiyue in the south, and so many countries in the west, as well as Greece and Rome. They have a lot of world for them to develop.

The famous experts felt that since hundreds of schools of thought were now in Xianyang, they would start to make noise sooner or later. The Legalists could not think of being judges from above. They were famous eloquors who were good at eloquence and had no political stance, so they were particularly suitable for calming down everyone.

In other words, relying on eloquence to mediate conflicts and maintain stability.

The two groups of people looked at each other and smiled, passed the customs together, and rushed to Xianyang.

In front of Confucianism, everyone can be a friend.

Some people from different branches of Confucian sects also began to pack their bags and rush to Xianyang. They could not let other sects take the lead.
