Chapter 54: Education for All

Chemical energy can be converted into electrical energy, but it is not ready for a while. It is too late to prepare now. It is better to abstract points. Even if there are some abstractions, with their understanding, it is not a problem.

Chen Wanrong looked at Princess Jinxian and said, "Princess, you have beautiful hair, shiny and elegant, and you are extremely beautiful."

Princess Jinxian's face turned red and she felt a little embarrassed, but Princess Yuzhen curled her mouth and glared at Chen Wanrong fiercely.

Chen Wanrong ignored her and then said, "Whenever the princess dresses up, if the comb is close to lighter things, such as paper confetti and silk, she will find that the paper confetti will be dipped on the comb, and the silk will be a little ethereal. What is the reason? It is because the comb is charged."

"Ah! That's electricity? Why didn't we see it?" The ancients all raised their hair, and dressing up was not just a matter of women, but men also dressing up. They had this kind of experience and couldn't help but talk.

Chen Wanrong saw their surprise appearance and smiled slightly and said, "Electricity is invisible and can be felt. Combing the hair is a frictional generation of electricity, and the electricity is very small, and it doesn't feel obvious. Of course, electricity is widely used. If the research is successful, it can completely replace the steam engine and is a good power. Therefore, we need a lot of electricity, and we cannot rely on frictional generation of electricity like combing the hair, but we have to obtain it by other methods."

"What method? Tell me quickly!" Everyone stretched their necks in surprise.

They are good workers and scientists. Of course, what they care about most is the method. This is something beyond imagination. Everyone is excited and their breathing is a little rapid.

Chen Wanrong continued: "We use hydraulic power to make cement without power. It is a coincidence that there are many ways to get electricity, but the cheapest and most convenient way is to use hydraulic power. You may find it strange, how can flowing water become electric energy for us to use?"

"It's not strange, it's very... strange!" Ye Tianheng said so many words "very" in one breath to express his doubts.

This was said to everyone and he nodded.

Chen Wanrong smiled slightly and said, "Master, don't worry, I'll tell you now. Turning hydraulic power into electricity requires machinery. This machine is a generator, divided into stator, rotor, end cap, base and bearing. What I'm talking about now is just roughly the same, and the specific one depends on you to study. We now have machine tools and we have a foundation to make generators."

Next, according to the memory, the composition and principles of the generator are explained one by one.

Fortunately, I didn’t get away with the physics when I was studying, so I still remember it clearly, otherwise it would have been a mistake for others and myself.

The manufacturing of generators is very difficult, and the knowledge in the physics textbooks is far from meeting the requirements. However, it is enough to point out the direction, and even this knowledge makes everyone lose their eyes. When Chen Wanrong finished speaking, they all opened their mouths wide and couldn't even say anything.

"Everyone, what do you think?" Chen Wanrong asked.

Everyone then realized that they stood up excitedly. Ye Tianheng couldn't help but wipe the cold sweat on his forehead: "Oh my God! If I hadn't heard it with my own ears, I really wouldn't believe that there was such a wonderful thing. Don't say it was made, even if you listen, you would be satisfied in this life! So satisfied!"

These words were everyone's voice, and they were all echoing. For a moment, there were constant buzzing sounds in the room, and everyone was so excited.

The excitement of everyone has not disappeared, and Chen Wanrong's next words made them even more excited: "With electricity, it is just the beginning, and we have to apply it well. How to apply electricity? This requires manufacturing equipment and providing us with convenience. Electricity is a good kinetic energy, and we can make motors. With electricity and with motors, we can make electric locomotives without having to use steam engines to push them."

Liang Lingzan was a little confused: "General Chen, electricity has so many uses, should electricity be used or steam engines?"

Chen Wanrong explained: "In my opinion, although electricity is easy to use, its technical difficulty is too much. Without decades of hard work, it may not be completed. Therefore, I think it is better to use a steam engine first. We have to study electricity. When the technical conditions are ripe, it will not be too late to use electricity again."

According to Chen Wanrong's estimate, even if he pointed out the direction, it would be impossible to achieve the power without long-term efforts. This time, at least ten years, forty or fifty years, or even longer.

The length of time does not matter, it is important to do this.

"Oh!" Liang Lingzan understood, and said oh, stopping talking.

Chen Wanrong continued: "In addition to being used as power, electricity can also be used for lighting. Its brightness is much brighter than the oil lamps we use now. It can be said that if there is an electric lamp in this room, even on a night when you can't see your fingers, the room will be as bright as daytime."

Even if the generator is built, it will be in vain if there is no matching application technology. It is just a decoration. Only by finding a purpose for electricity can electricity develop. It is precisely because of this that Chen Wanrong spent a lot of time explaining the application of electricity.

Liang Lingzan and the others had many questions, and Chen Wanrong answered questions and tried his best to make them understand. By the time Chen Wanrong finished speaking, he had no idea how many cups of tea he had drunk.

When everyone realized that it was almost dark, everyone went home. Chen Wanrong and Sima Chengzhen returned home together, and they had to discuss with him about the new explosives in the evening.

As soon as the two arrived at the mansion, they saw Zheng Qing and Qing'e standing shoulder to shoulder at the door, their necks stretched out and they couldn't help looking around. Chen Wanrong jumped off the horse, hugged Zheng Qing's slender waist, and teased: "Wife, are you waiting for me?"

Qing'e gave Chen Wanrong a blank look and quickly turned her face aside. Sima Chengzhen looked at the sky and pretended not to see it.

Zheng Qing struggled slightly, but she didn't struggle anymore without breaking free. Her face turned red and she angrily said, "Let go, there are people here."

"What's wrong with someone? I'm close to my wife, who can say what?" Chen Wanrong's face was thick-skinned.

"I'm so thick-skinned!" Zheng Qing raised her right hand and gently patted Chen Wanrong on the face, giving him a blank look.

Seeing that he had been teasing enough, Chen Wanrong let her go and smiled and said, "My wife, I haven't seen me for so long, do you miss me?"

"Go! The dog's mouth cannot spit out ivory!" Zheng Qing lowered her head in shame.

Chen Wanrong held her jade hand and then went into the house with Sima Chengzhen. Chen Laoshi and his wife came up with a smile. Chen Laoshi shouted from afar: "Wanrong, you are just back now, you have to learn from Zairong. Zairong will have been back long ago."

Chen Wangshi continued to maintain Chen Wanrong: "You are the leader, please say less, Wanrong is a problem. It's not like you, you stay at home all day long, do nothing, and look like you are useless!"

"I'm not promising?" Chen Laoshi was very dissatisfied.

Chen Wangshi replied bluntly: "You are not successful anywhere!"

Chen Zairong came over with a smile and greeted Sima Chengzhen: "I have seen my master."

"Zairong, no gift!" Sima Chengzhen took Chen Zairong's hand very lovingly, looked left and right, and was very happy: "Zairong, you have captured Mochu alive this time, and you have made great contributions. I am happy for your teacher!"

I took over a disciple like Chen Zairong on a whim. Unexpectedly, Chen Zairong is so showing up now. He, a master, also gained money, and smiled so hard that he could not close his mouth.

Before the trouble was over, Zheng Jianqiu's voice sounded: "Wanrong, you are back!"

When Chen Wanrong saw Zheng Jianqiu and his wife came in from outside with a smile. Needless to think about it, they came to see their son-in-law. Chen Wanrong hurriedly greeted him: "I have met my father-in-law! I have met my mother-in-law!"

Zheng Jianqiu hurriedly stopped him, took Chen Wanrong's hand intimately, and said, "Wanrong, I just said that you have to go back to Chang'an, there are so many things you have to go back to your house directly. You have to wait until it gets dark before you can see your people. If your mother-in-law doesn't believe me, am I right?"

Zheng Zhou smiled and said nothing else. I thought that the couple must have argued a lot about seeing Chen Wanrong.

Zheng Jianqiu patted Chen Wanrong's shoulder and said, "Wanrong does a big thing, how could he be as in love with his home as we do! Wanrong, is his father-in-law right?"

Chen Wanrong smiled and said, "Where did my father-in-law say? I couldn't get rid of it if I have something to do. I've wanted to come back and see it, but there's too much business, and there's no way."

"Men, that's what it means!" Zheng Jianqiu raised his thumb and praised him endlessly.

Zheng Qing hurriedly invited everyone into the room, served tea, sat next to Chen Wanrong, and looked at Chen Wanrong very gently. She had thousands of words to say to Chen Wanrong, but now is not the time.

I originally wanted to talk to Sima Chengzhen about the new explosives, but now I have no chance, so I can only talk with Zheng Jianqiu and the others. This is not bad, and family affection makes people warm.

As he was talking, someone complained outside: "When Chen Wanrong, a guest came, he didn't come out to greet him, and there was no etiquette at all."

"The emperor is here!" Everyone knew that it was Li Longji who had arrived and hurried to greet him.

Li Longji came in with a smile, Princess Jinxian and Princess Yuzhen, and Gao Lishi followed him. Everyone hurriedly greeted him, and Li Longji waved his hand and said, "Look, I am in a sub-district interview today, so there is no need to be polite."

He didn't tell any lies, he didn't wear a royal robe, he just wore plain clothes, and looked relaxed.

After seeing the ceremony, they asked them to sit down. Chen Wanrong was a little curious. Before he could ask, Li Longji spoke first: "Chen Wanrong, are the things you said today in the military weapon supervisor real?"

Chen Wanrong looked at Princess Jinxian and Princess Yuzhen, and then said, "Your Majesty, every word I say is the truth. If there is a half false statement, I am willing to surrender the law."

"Don't say it so seriously, I want to confirm it." Li Longji went straight to the topic and said, "What you said is true, and you have to do it no matter what. This is a big thing that benefits the world. This steam locomotive has such a large car carrying capacity, which is a very convenient thing. No matter how big the difficulty is, it must be completed. Think about it, with the steam locomotive, the army will not have to worry about not being able to supply, and a truck will transport hundreds of thousands of kilograms. This is a big deal, and the railway must be built!"

Li Longji had a far-reaching vision. Although he had never seen a train, he knew how effective the train was. Not to mention anything else, it was an immediate effect to use it to replenish the army. With a train, there was no need to send hundreds of thousands of people to transport it at any time like before. The cost difference was too far.

With his words, Chen Wanrong's confidence became more and said, "Prince, please let go, I will do my best."

Li Longji continued: "The electricity you mentioned has so many uses, and you have to find a way to do it. I believe that as long as you spend time, these will be achieved. The problem is that this requires a lot of manpower. Where do you plan to find manpower? The Imperial College will not draw any more people, and the county government cannot draw any more people. If the county government draws it again, where will the army find people in the future? Although what you said is good, it cannot shake the foundation of the army."

The Tang Dynasty county hall wanted to provide talents to the army. Most of the officers of the Tang army were educated county hall students. This was related to the stability of the country, and Li Longji would definitely not take this risk.

After a moment of pause, Li Longji frowned and said, "Even if you say, bringing the talents of Dashi and Daqin to Chang'an is not enough. Just the current work is very tight. At most, their arrival is just to do what is in front of you."

The manpower is indeed a big problem, a problem that bothers people. Princess Jinxian and Princess Yuzhen stared at Chen Wanrong with their eyes. It was obvious that they were also worried about this matter.

Chen Wanrong really didn't think about this. At that time, he just thought that it would take a long time to go to the Western Regions. He should have arranged these things, but he didn't think about the others.

After hearing Li Longji's words, he couldn't help but frown. Li Longji saw it and said, "If there is no one, everything will be empty talk."

"I have it!" Chen Wanrong hit his hands hard and said, "Master, we can train ourselves!"

Li Longji shook his head and said, "I have thought about this. It will take a long time to avoid water from quenching thirst."

Chen Wanrong said seriously: "The emperor is right. Even if we train it now, it is too late. However, this doesn't matter, because we don't know when these things can be made. Maybe ten years, maybe twenty years, maybe longer. Please think, after such a long time, we will start cultivating now. In a few years, will there be a large number of people who can use them?"

Li Longji nodded and said, "The words are good, this proposal is feasible. I will issue an order to choose some smart boys to train you."

Chen Wanrong shook his hand and said, "Your Majesty, never!"

"What's wrong with this? Isn't our military weapon surveillance doing this?" Princess Yuzhen was a little anxious and couldn't help but say it.

Chen Wanrong explained: "Your Majesty, please think, steam locomotives and electricity alone require a lot of people. After these are done, we have more things to do. Technology will always improve, and there will be no stopping. The more talents the better. In order to do something, we will select a group of people to train. If we continue to do this, we will never fundamentally solve the problem. This matter is solved, and it will be like this again until the next thing, and this is not a good solution."

It is a taboo thing to say bluntly that the emperor's method is not good, but Li Longji didn't care at all, but instead taught him humbly: "What do you think should you do?"

Chen Wanrong gave an idea and said, "Your Majesty, according to my knowledge, studying in the Tang Dynasty became a trend, and five-foot boys were ashamed of not speaking about poetry and books. This is very good. I want to let all the people learn, and the best among them can enter higher-level schools to study. Isn't there a Imperial College in the Tang Dynasty? The students of the Imperial College come from the county hall, and the students of the county hall come from the outstanding children of the people.

"We can do this in science and technology. Of course, poetry and books have existed for thousands of years and can be recited by the people. Technology cannot be like this because it must be kept confidential. Even so, we can compile some basic knowledge into textbooks for them to learn. We can set up schools in the countryside so that all children of appropriate age can learn. Those who have achieved success can choose to study at county halls, and then from county halls to university of science and technology to study."

This method is very fresh. Li Longji's eyes suddenly opened wide, staring at Chen Wanrong, thinking for a while, saying, "It's good, but this is too large!"

"It is necessary to be large in scale, so that it can be called universal education! I must seize this opportunity to promote universal education! With universal education, why worry about not having talents?" Chen Wanrong was very excited and secretly warned himself.

Chen Wanrong was determined to stimulate Li Longji: "Master, aren't you afraid?"

"I'm afraid? What's so scary about me?" Li Longji's voice raised Lao Gao, with anger.

Chen Wanrong ignored his anger and continued, "The emperor is wise! Everything is not difficult, I am afraid of someone who is determined to do it! As long as the emperor is determined to do it, I will definitely do it well! The emperor, please think, if you really want to do this, the Tang Dynasty is still worried about not having talents? Are you still worried about not being able to make steam locomotives and electricity?"

This matter was too big. Li Longji did not express his opinion immediately, but began to ponder. After thinking for a while, he said, "That's it! But where did you find so many teachers who teach people for a while?"

Chen Wanrong had long been convinced about this matter: "Your Majesty, I think this matter is not difficult. Hasn't our military weapon supervisor trained a group of people? Is it possible for them to be willing to teach and educate people to take on this matter."

"The idea is good, but they haven't learned much time. Can this work?" Li Longji still had concerns.

"I will keep this matter in a good way." Chen Wanrong was very confident.

Even if their level is not good, it is better than nothing. Think about it, when the founding of New China, in order to run a school, there were no teachers, so they could only teach those who had been to private schools for a few days, and they would teach for a lifetime. Until now, college students are on the road and are mostly unemployed.

It’s not that I’m afraid of being bad, it’s that I’m afraid of not doing it!

Li Longji commented: "Looking for talents from the Western Regions can certainly solve temporary urgent problems, but not long-term solutions. What you are talking about now is the fundamental and can solve this problem permanently. I will issue an order when I go back and implement it immediately!"

At this point, it should have stopped, but Chen Wanrong was not satisfied: "Your Majesty, I have not said a word yet, I don't know whether to speak or not."

"Tell me!" Li Longji was very happy.

Chen Wanrong did not say immediately: "Your Majesty, this matter is of great importance. I would like to forgive me for your crimes, so I dare to say it."

Li Longji frowned and said, "No matter what you say, I will forgive you for being innocent!"

"Thank you, the emperor!" Chen Wanrong was very excited and his voice rose: "Your Majesty, I want to recruit students, not only men, but women, but also women. Not to mention anything else, just say that the two princesses are not allowed to be sore girls in the military weapon surveillance. Among the women, there are also amazing women who do not allow berets, and they cannot leave."
