Education is the foundation of a country, and talent is the foundation of a strong country.

And talent is obtained from training.

In Jinling School, in a classroom, Zhao Hong was standing on the podium, talking endlessly to the students in the classroom, concentrating on "misleading people's children".

On his side, there was a tin kettle on the honeycomb coal stove, and the mouth of the kettle was steaming, and the lid of the kettle was lifted, and it sounded "dangdang".

"Did you see, when the water in the kettle boils, the water vapor can lift the lid of the kettle and make it move up and down. If a large pot of water is boiled and the resulting water vapor is transmitted as power, what will it promote? ”

A steam engine, which converts thermal energy into mechanical energy. The boiler has a piston with a drive rod, and when the boiler is heated, the water vapor produced by the boiling of water in the boiler pushes the piston and converts the internal energy into mechanical energy. After the work of water vapor is done, the internal energy decreases, and it will condense into water again, and the piston returns to the starting point. In this way, the steam engine does work on the outside world in a cycle, pushing it into constant motion.

It was the steam engine that gave rise to the first industrial revolution and ushered in the era of replacing manual labor with machines. Britain, which was the first to complete the industrial revolution, became the world hegemon of the times.

Seeing that although the students were full of curiosity, they were sitting in a precarious position, silently one by one, Zhao Hong couldn't help but get angry.

These powerful children of Lin'an Mansion, after more than half a year of school education, still can't support the wall with mud?

Doesn't it mean that even a piece of toilet paper has its uses?

"Everyone has visited the Jiangnan Ordnance Manufacturing Division, and the coal washing, air blasting, and hydraulic calcining hammers during iron smelting are all crank connecting rods generated by water power and transformed into reciprocating motion. Think about it, what would it be like if boats were not rowed by people and cars were not led by horses, but were replaced by power generated by water vapor? ”

Zhao Hong drew a simple diagram of a steam engine on the blackboard, with a boiler, pistons, and a crank linkage.

He also didn't know how to build a steam engine, but he came from the era of the big bang of knowledge, he knew the general structure of the steam engine, and he also believed that with so many young people, someone would always come out to build it.

"Here, I will illustrate a truth, that is, the law of conservation of energy. Energy is neither destroyed nor created, it is only transformed from one form to another, or transferred from one object to another, and in the process of transformation and transfer, the total amount of energy remains the same. For example, the burning of charcoal produces heat energy, and boiling water also produces water vapor, which washes the lid of the kettle. ”

Zhao Hong imparted knowledge, the only thing in his head.

In fact, he taught the same thing in the Jinling Lecture Hall. Interest is the best teacher, and he also hopes that these young people do not have to join the army and politics, to innovate, to ponder strange skills, but also to reflect their own value.

"Headmaster, if you punch someone else, your fist hurts, isn't that the truth?"

Finally, one of the students raised their hands, stood up, and asked.

Straighten your waist with your palms down, lay flat on your knees, raise your head and chest, and don't squint.

Yang Hui, who was at the back of the classroom, listened carefully and observed, and shook his head secretly.

Every move, well-behaved and orderly, like a soldier. The original carelessness and hanging children should be gone, and everyone is plain.

This is only the first year, and if you study for three years, you can expect the growth and transformation of the younger generation.

Headmaster Emperor, what else are you not satisfied with?

"Yes, this is also called action and reaction. When you swim in the water, your feet kick backwards, and the water is subjected to backward force, and the human body is subjected to the forward reaction force, which is the propulsion force obtained by the human body. ”

Zhao Hong nodded, his face gentle.

"Headmaster, the gunpowder burns, and the iron ball is pushed out, is it also possible...... Conservation of quantities...... Law? ”

Another student then asked.

"Yes, the burning of gunpowder creates a huge impetus that pushes the shell out of the chamber. The more gunpowder, the greater the propulsion, and this is the case with the explosion. ”

Zhao Hong said loudly, with a smile on his face.

"Headmaster, if you use steam to produce ...... Power, the power of the big water tank is too great, what should I do if the water tank is broken? ”

"Principal, if you use water vapor and the cold water vapor condenses into water, you can find a way to extract the condensate."

The students spoke one after another, which was the same as the reaction of the students of the Jinling Lecture Martial Arts Hall.

Zhao Hong unconsciously exhaled secretly.

Even a piece of toilet paper is definitely valuable.

"If the pressure generated by the steam is too high, maybe it will explode, can it be solved with a valve? If the pressure is too high, the steam will burst open the valve, and if the pressure is low, the valve will automatically close, similar to the lid of this kettle. ”

Zhao Hong replied softly, and his mood was much more relaxed.

Originally, the first batch of students in Jinling Academy had a semester of three years, and it seems that next spring, that is, at the end of the first academic year, the young people of the entire Great Song Dynasty will be able to enroll.

It can't be because of these two or three thousand powerful children that the future of thousands of young people in the Great Song Dynasty has been hindered.

At that time, a group of students can be assigned from the Jinling School and the Jinling Lecture Hall to the Jiangnan Ordnance Manufacturing Division to specialize in the research and development of steam engines.

Without a large number of talents, how can it be possible to push the Great Song Dynasty forward?

"Ladies and gentlemen, I plan to create a branch in the Jiangnan Ordnance Manufacturing Division, which is dedicated to the study of steam engines. The personnel consisted of officials from the Ministry of Industry, craftsmen and students from Jinling University. Those who are interested can sign up, they are all officials of the imperial court. As long as you can build a steam engine, the court will definitely not be able to treat you badly. ”

When the excitement came, Zhao Hong immediately threw out a bomb.

"Students, if the steam engine is successfully developed, it will be a feat in history, a revolution, and it will change the fate of the entire Great Song Dynasty. The boat does not need to be rowed by anyone, the car does not need to be pulled by anyone, and it is no longer a dream to travel thousands of miles a day. ”

With the current level of iron smelting in the Great Song Dynasty, it should not be difficult to build a steam engine.

"Headmaster, I'm willing to go!"

"Headmaster, I'm willing to go too!"

"Headmaster, I'm willing to go!"

Immediately, some students raised their hands to sign up, although the number was not large, but it was also exciting.

"Excellent! You can sign up with the school when you go back. However, everyone should learn knowledge, especially mathematics and iron smelting. ”

Zhao Hong nodded and continued to strike while the iron was hot.

"Some court secrets, and I am not afraid to tell you that the Jiangnan Weapons Manufacturing Division is developing firearms and ironclad ships. The Musket is a tiny cannon, similar to the Assault Gun, but capable of shooting at a hundred paces. As the name suggests, the ironclad ship is made of steel, which can be used across the ocean and is durable. ”

He also taught to the students of the lecture hall in Jinling, hoping that more young people would devote themselves to it and form a huge scientific and technological research team.

"Headmaster, I'm willing to go!"

"Headmaster, I'm willing to go too!"

This time, there seems to be a lot more people raising their hands to sign up.

"In addition, the imperial court established Daye Iron Works on Jiangnan West Road, which was very large-scale and needed a lot of talents. If you are willing to go, you should first refine the good steel, which is also a great matter for the benefit of the country and the people. In addition, the porcelain industry glass in Jingdezhen, Jiangnan East Road, also needs a large number of young students to go, you may wish to consider it. ”

In fact, he does not seem to need to do such mobilization. When Jinling University begins to recruit private children next year, there will be many people who want to go after graduation. He was just too anxious and wanted the steel industry of the Great Song Dynasty to get on the right track as soon as possible.

This time, there seemed to be very few responders.

It seems that the so-called strange skills and tricks of Shinong industry and commerce do not seem to be so important and affordable in the minds of the students.

"Don't look down on iron smelting and porcelain making, it's so ambitious, just thinking about getting promoted and making a fortune, it's not such a good thing!"

Wei Liaoweng said coldly, his face pale.

"Yang Fansun, Zhang Wei, and you, what are you capable of and what can you do? If you leave your family, you will go out, and no one will ask for coolies, and you will not starve to death! ”

Wei Liaoweng showed no mercy, and the faces of many students in the classroom turned red.

Pampered, eating and drinking without worrying about things like "starvation", they never seem to have thought about it.

Zhao Hong was secretly surprised. He also didn't expect that Wei Liaoweng, a scholar who "learns and excels", would teach these sons and brothers a lesson with "practice".

"What do you see, are you not convinced? Governing the people to make a living, talking about martial arts to protect their cowards, weiling water to benefit the fields, and calculating the calendar to clear numbers, what do you all know? Taxes, case severing, water conservancy, iron smelting, casting firearms? You don't understand anything, you hang around all day long, who do you think you are? Do you have to be in the court? ”

As the vice president of Jinling University Hall, Wei Liaoweng was unceremonious. has been with the emperor for a long time, and in terms of "pragmatism", he has indeed changed a lot.

"Even if you can become an official, you have to start from the bottom, and now the court has strict laws, anti-corruption and anti-corruption, and advocates the rule of officials. Don't even think about bending the law for bribes or accepting bribes. Once the law is violated, Gu Song, Hu Yuanfeng and others will be the end. Don't forget, next year, Jinling University will recruit students from the people, and those young people are not as squeamish as you! ”

The classroom was silent, and it was obvious that the students were all dumbfounded by Wei Liaoweng's blow.

Will those ordinary people rob them of their jobs?

"Ladies and gentlemen, what Vice President Wei said is right, the era of being an official for thousands of miles, just to be promoted and make a fortune, is gone forever. In the future, you still have to be innocent and do things with peace of mind, otherwise you will mislead others and yourself, and it will be too late to regret it. ”

Zhao Hong quickly changed the topic and returned to compulsory education and normal school.

"The establishment of Jinling University Hall by the imperial court is not to let all of you become officials. To do technical practice, or to teach and educate people, a variety of choices, a hundred flowers bloom, this is the original intention of the imperial court to establish Jinling University. ”

To do technical work, such as iron works, gunpowder factories, porcelain factories, and so on. 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 a hundred flowers will bloom.

"Students, I believe many of you have read the newspaper that I want to implement compulsory education in the Great Song Dynasty, and children between the ages of 6 and 15 must be enrolled in school, and tuition and miscellaneous fees are all free. Since compulsory education is to be introduced, a large number of teachers are needed. And among you who have both ability and political integrity, many of you will go to schools at all levels to solve their doubts. ”

Most of the students of Jinling Academy will go through three years of complete study, and those with good character and learning will go to primary and secondary schools to teach to promote the popularization of compulsory education.

Of course, it also depends on whether the students are voluntary, and the court will not force it.
