Education is the foundation of a country, and talents are the foundation of a strong country.
Talents are obtained through training.
In a classroom at Jinling Academy, Zhao Hong was standing on the podium, talking incessantly to a classroom full of students, concentrating on "misleading students."
Beside him, there was an iron kettle placed on the briquette stove. The spout of the pot beeped with steam, and the lid of the pot was raised, making a "dang" sound.
"Have you seen that when the water in the kettle boils, the water vapor can push up the lid of the kettle, causing it to move up and down. If a large pot of water is boiled, the generated water vapor will be transmitted out as power, What will be promoted?”
Steam engine converts thermal energy into mechanical energy. There is a piston with a transmission rod on the boiler. When the boiler is heated, the water vapor generated by the boiling water in the boiler pushes the piston and converts the internal energy into mechanical energy. After the water vapor does work, the internal energy decreases, and it condenses into water again, and the piston returns to the starting point. In this way, the steam engine performs work on the outside world cyclically, pushing it to move continuously.
It was the steam engine that produced the first industrial revolution and ushered in an era in which machines replaced manual labor. Britain, which took the lead in completing the Industrial Revolution, became the world hegemon of the era.
Seeing that although the students were full of curiosity, they were sitting upright and silent, Zhao Hong couldn't help but feel angry.
Could it be that these powerful children of Lin'an Prefecture, after more than half a year of school education, are still unable to hold up the wall?
Doesn’t it mean that even a piece of toilet paper has its use?
"Everyone has visited the Jiangnan Ordnance Manufacturing Branch. Coal washing, air blasting, hydraulic hammers, etc. during iron smelting all use the crank connecting rod generated by water power to convert it into reciprocating motion. Think about it, if the ship does not need people to row, What would it look like if the carriage didn't need horses to pull it, but was powered by water vapor instead?"
Zhao Hong drew the simplest diagram of a steam engine on the blackboard, including a boiler, piston, and crank-connecting rod mechanism.
He also doesn’t know how to build a steam engine, but coming from the era of the explosion of knowledge, he knows the general structure of a steam engine. He also believes that there are so many young people that someone will come out to build it.
"Here, I explain a truth, which is the law of conservation of energy. Energy will neither be destroyed nor created. Energy will only be converted from one form to other forms, or transferred from one object to another. During the process of conversion and transfer, the total amount of energy remains unchanged. For example, burning coal produces heat energy, boiling water also produces steam, and opening the lid of a kettle."
Zhao Hong imparted knowledge, which was the only thing in his mind.
In fact, he taught this way at the Jinling Martial Arts Lecture Hall. Interest is the best teacher. He also hopes that these young people do not have to join the military or politics, they can innovate and figure out strange skills, and they can also reflect their own value.
"Principal, if you punch someone else, your fist will hurt. Is that true?"
Finally, some students raised their hands, stood up, and asked.
Keep your waist straight, palms down, flat on your knees, raise your head and raise your chest, without squinting.
Yang Hui at the back of the classroom listened carefully and observed, shaking his head secretly.
Every move is neat and orderly, just like a soldier. The original carelessness and carelessness are gone, and everyone is indifferent.
This is only the first year. After three years of study, the growth and transformation of the younger generation can be expected.
Emperor Principal, what else are you dissatisfied with?
"Yes, this is also called action force and reaction force. When we swim, we push our feet backwards in the water. When the water receives a backward force, the human body receives a forward reaction force. This is the propulsion force obtained by the human body."
Zhao Hong nodded with a gentle expression.
"Principal, when the gunpowder burns and the iron ball is pushed out, is it also the law of conservation of energy?"
Another student asked next.
"Yes, the burning of gunpowder produces a huge driving force, which pushes the cannonball out of the barrel. The more gunpowder, the greater the driving force generated. This is the reason why the barrel is exploded."
Zhao Hong said loudly, with a smile on his face.
"Principal, if steam is used to generate... power, the power of the large water tank is too great and the water tank breaks."
"Principal, if water vapor condenses into water when encountering cold water, you can find a way to extract the condensed water."
The students spoke one after another, with the same reaction as the students at Jinling Martial Arts Hall.
Zhao Hong secretly exhaled without realizing it.
Even a piece of toilet paper definitely has its value.
"As for the pressure generated by the steam that is too high, an explosion may occur. Can a valve be used to solve the problem? If the pressure is too high, the steam will open the valve. If the pressure is low, the valve will automatically close, similar to the lid of this kettle. "
Zhao Hong replied softly, feeling much more relaxed.
Originally, the first batch of students at Jinling Academy had a three-year term. It seems that next spring, at the end of the first academic year, young people from the entire Song Dynasty will be admitted.
We can't let these two or three thousand powerful children hinder the future of thousands of young people in the Song Dynasty.
At that time, a group of students from Jinling Academy and Jinling Martial Arts Hall can be assigned to the Jiangnan Arms Manufacturing Branch to specialize in the research and development of steam engines.
Without a large number of talents, how could it be possible to push the Song Dynasty forward?
"Dear students, I plan to create a branch in the Jiangnan Arms Manufacturing Branch specifically for the research of steam engines. The staff will be composed of officials and craftsmen from the Ministry of Industry and students from Jinling University. Those who are interested can sign up. They are all officials of the imperial court. As long as If you can build a steam engine, the court will never treat you badly."
When he was excited, Zhao Hong immediately threw a bomb.
"Students, if the steam engine is successfully developed, it will be a feat in history, a revolution, and will change the destiny of the entire Song Dynasty. Boats do not need people to row, cars do not need people to pull, and traveling thousands of miles a day is no longer a dream."
With the current level of iron smelting in the Song Dynasty, it shouldn't be difficult to build a steam engine.
"Principal, I am willing to go!"
"Principal, I'm willing to go too!"
"Principal, I am willing to go!"
Immediately, students raised their hands to sign up. Although the number was not large, it was exciting.
"Very good! You can register with the school later. But you must learn knowledge well, especially mathematics and iron smelting."
Zhao Hong nodded and continued to strike while the iron was hot.
"There are some secrets of the imperial court, and I am not afraid to tell everyone. The Jiangnan Weapons Manufacturing Branch is developing firecrackers and armored ships. Fireguns are small artillery pieces, similar to muskets, but they can kill opponents with a hundred steps. Ironclad ships, as the name suggests, are ships. Made of steel, it can travel across oceans and be durable.”
He also taught classes at the Jinling Martial Arts Hall to the students in the Martial Arts Hall, hoping that more young people would join in and form a huge scientific and technological research team.
"Principal, I am willing to go!"
"Principal, I'm willing to go too!"
This time, there seemed to be a lot more people raising their hands to sign up.
"In addition, the imperial court established the Daye Iron Works on Jiangnan West Road. It is very large and requires a lot of talents. If you are willing to go, make good steel first. This is also a major event that will benefit the country and the people. In addition, Jiangnan East Road The porcelain and glass industry in Jingdezhen also requires a large number of young students to go there, so you may wish to consider it."
In fact, it seems that he does not need to do such mobilization. When Jinling University starts recruiting private students next year, there will be many people who want to graduate. He was just too anxious and wanted the Song Dynasty's steel industry to get back on track as soon as possible.
This time, responses seemed to be few and far between.
It seems that scholars, farmers, industry and commerce, and the so-called miraculous skills are not so important and valued in the minds of the students.
"Don't look down on those who smelt iron and make porcelain. They are so lofty and ambitious. Just thinking about getting promoted and getting rich is not that good!"
Wei Liaoweng said coldly, his face ashen.
"Yang Fansun, Zhang Shu, and you, what abilities do you have, what can you do? After leaving your family, no one wants you to work hard, and you have to starve to death!"
Wei Liaowen showed no mercy, and the faces of many students in the classroom turned red.
They seem to have never thought about things like "starving to death" for the pampered boys who have no worries about food and drink.
Zhao Hong was secretly surprised. He also did not expect that Wei Liaoweng, a scholar-bureaucrat who "learns well and becomes an official", would teach these young men a lesson with "practical practices".
"What are you looking at? Are you dissatisfied? Governing the people to ensure their livelihood, teaching martial arts to ward off the invaders, weiring water to benefit the fields, calculating calendars to clarify the numbers, what do you know? Taxation, settling cases, water conservancy, iron smelting, and firearms casting? You You don't understand anything, you just do nothing all day long, who do you think you are? Do you have to be the one in charge of the imperial court?"
As the vice president of Jinling University, Wei Liaowen was not polite. After staying with the emperor for a long time, he has indeed changed a lot in terms of "pragmatism".
"Even if you can become an official, you have to start from the bottom. Nowadays, the imperial court has strict laws, fights against corruption, and advocates clean government. Don't even think about taking bribes, bending the law, and accepting bribes. Once they violate the law, Gu Song, Hu Yuanfeng, and others will The end. Don’t forget that Jinling University will recruit students from the private sector next year, and those young people are not as squeamish as you!"
There was silence in the classroom. Apparently, the students were stunned by Wei Liaoweng's blow to the head.
Will those common people take away their jobs?
"Dear students, what Vice President Wei said is right. Gone are the days when you worked thousands of miles to become an official just to get promoted and get rich. In the future, you should still be clean and honest, and work with peace of mind, otherwise you will mislead others and yourself. , it’s too late to regret.”
Zhao Hong quickly changed the topic and returned to compulsory education and normal school.
"The imperial court did not want all of you to become officials when it founded the Jinling University. It was to do technical work, or to teach and educate people. A variety of choices, allowing a hundred flowers to bloom. This is the original intention of the imperial court to establish the Jinling University."
Go and do technical work, such as going to the iron factory, gunpowder factory, porcelain factory, etc. You can also choose to be a teacher and teach and educate people. Of course, you can also go into business on your own and let a hundred flowers bloom.
"Students, I believe many of you have read the newspaper. I want to implement compulsory education in the Song Dynasty. Children aged 6-15 must enter school with free tuition and miscellaneous fees. Since we want to implement compulsory education, we need a large number of teachers. And those of you who have both ability and political integrity, many of you will go to schools at all levels to resolve your doubts.”
Most of the students at Jinling Academy have to go through three years of complete study. Among them, those with good character and academic performance will go to teach in primary and secondary schools to promote the popularization of compulsory education.
Of course, it also depends on whether the students are willing. The court will not force it.
