Chongzhen and I became partners

Chapter 340 Attending Class (asking for a monthly ticket)

The emperor, it is basically impossible to be humble, and it is impossible to be humble in this life!
Being good at being a teacher is a common problem of emperors!

Being able to prove that you are wise and powerful is the joy of being an emperor!
At this time, Emperor Chongzhen heard Li Dingguo's request, thought for a while and said with a smile: "Quick play!"

When Liu Wenxiu and Yuan Zhuangfei heard this, they also thought about it, so they quickly brought it up, and Emperor Chongzhen agreed again.

On the contrary, Zhou Yuji served Emperor Chongzhen the longest, and after hearing a lot, he probably understood what was going on with the steam engine.And his interest was in military affairs, and he didn't get involved.

Afterwards, Emperor Chongzhen finally got back to business, told the generals below about Sun Chuanting's strategic plan, and then said to Zhou Yuji: "Nowadays, the Henan War is coming soon, but the Jinyiwei Supervising Army is seriously insufficient, and there is no time for the new Jinyiwei Supervising Army to get acquainted." Therefore, the Jinyi Guards in the Beijing camp will be dispatched to the Fifth Gezuo Battalion. In addition, the Beijing camp must also be prepared, and if the battle goes wrong, they will also go south for reinforcements!"

Since it was decided last year that a large number of Jin Yiwei would be placed in the army as supervisors, the number of Jin Yiwei's manpower has become more and more insufficient.In particular, Li Ruolian, the commander of the Jinyiwei, dispatched a large number of people to go south to the governor of Baoding to assist in the reorganization of the army, and there were not many Jinyiwei school lieutenants who stayed in the capital.

The Jinyi Guards in the Beijing camp were already familiar with how to be a good Jinyi Guards, so Emperor Chongzhen decided to transfer this part to the Fifth Gezuo Battalion.

As for the money and food needed for the war, Emperor Chongzhen decided to adopt Liu Weichao's proposal.For the sake of Da Ming's society, when it is time to show your face, you should show your face.Emperor Chongzhen, who already knew in his heart that he had once been the king of subjugation, had no embarrassment about it.

Therefore, he called Wang Chengen's name again and asked him to send people from Xichang to carry out the money and grain decree.

Li Dingguo and Liu Wenxiu who were nearby couldn't help being shocked when they heard this. They knew the current emperor again, and it was really different from the legends!
With a decree, the brigade's Xichangfan soldiers and more Jinyiwei supervisors rushed out of the capital one after another, and a big battle was about to begin.

However, on the side of the capital, there is no atmosphere of war at all, so it can be done as it should be. The people of the capital, especially the scholars in the capital, are most concerned about the emperor of the Imperial College personally teaching on this day.

Of course, the reason why they care so much is that the biggest gimmick is that the emperor teaches in person!
In addition, the content of this lecture was laid out first and placed there.

Sometimes, science is charming, especially those sciences that are close to the lives of ordinary people.

Forget about the high-ranking ones, what calculus, what conjecture, no one will care about that!

However, the steam train is already running in the capital and Tongzhou, and it will be connected to Tianjin in the future.

The speed of this train, as well as the weight it can pull, have subverted the imagination of people in this era.

As long as steam trains have been running, there have been discussions about steam trains!
Even cement roads are included. Countless people who step on the cement road will wonder how the material under their feet is made. Stones are not stones, and mud is not mud. Why are they not afraid of rainwater soaking?

There are so many doubts in normal times, and then because the Imperial College students have to pass the exam to select 50 students, more problems about daily life have been spread.

For example, the problem of slippery roads, the problem of beating people, and so on.

Most of these problems may be the same as usual, and subconsciously feel that this is the case, very common, nothing!
As a result, someone asked a question, thinking that this question would be easy to answer, but when he really wanted to answer it, he found that this question seemed impossible to answer!
Of course, there are also many people who try to use their own understanding to answer the questions in these most common phenomena.

Whether it's the scholar in the school hall, the farmer facing the loess and his back to the sky, or the rich lady hiding in the deep boudoir, or the boy playing and laughing, in short, no matter who they are, they can discuss these issues anytime, anywhere .

It can be said that these issues involving the most basic life have the highest participation rate!

In addition, there is another very nice word for this behavior of trying to answer, which is advocated by the sages, which is Gewu!

This makes this matter once again grand, and makes people want to try to explain these problems intentionally or unconsciously.

In short, among the scientific upsurge initiated by Emperor Chongzhen, it was the one with the highest number of participants.

And Emperor Chongzhen's lecture will answer these questions. Therefore, except for the fifty supervisors who can attend the lecture, everyone else is also paying attention to the content of this lecture.

When it was almost time for Emperor Chongzhen to give lectures, a large group of factory guards arrived at the Guozijian under martial law. Except for the 50 people attending the lectures, everyone else avoided.

However, places outside the martial law, especially places suitable for discussion, such as restaurants and teahouses, are full of people. They are discussing related issues while waiting for answers.

"At this moment, the Guozijian should have started, right?"

"Those people are really lucky to be able to listen to the emperor's personal explanation!"

"Hey, you said, does the emperor really know the truth about these questions?"

"Isn't this nonsense? The emperor doesn't even know, so why should you know?"

"Isn't it just that these knowledge must be related to Emperor Taizu's appearance, and it is knowledge that only immortals understand!"

"I don't care about anything else, I just want to know, how did the train get its strength?"

"..."

Amidst the discussions outside, Emperor Chongzhen had indeed visited Guozijian.In the classroom, there were Jinyiwei captains standing on both sides, and on both sides of the podium, there were also two generals standing, no, standing Liu Wenxiu and Li Dingguo.Of course, there were also several eunuchs from the Supervisor of Rites, including Wang Chengen.

These Guozijian students are old and young, but they all have one thing in common. They have never experienced such an occasion, and they are all a little excited and a little trembling.

Besides that, they're kind of weird.

Because on the side of the podium, there is actually a stove with a kettle on it, let’s boil water!

This should be the emperor's shelf, you have to drink hot water when you go out, and cook it now!

On the podium, Emperor Chongzhen looked at the crowd of supervisors below him, but he didn't put on a majestic posture. He just acted as a kind father, and asked with a smile: "Today, I will tell you a principle of energy conversion, and this is also true. The reason why the steam train is so powerful!"

"What is energy conversion? Let me give you a very simple example. When you walk, you have kinetic energy. When you fall from a height, you have potential energy. When you cook and cook, you have thermal energy..."

Li Dingguo on the side was listening carefully with his ears up. Hearing those unfamiliar words, his instinct told him that this is a good thing and the key!

Kinetic energy, potential energy, thermal energy?Does it still have cold energy, static energy, and low energy?This energy once seemed very profound!

Emperor Chongzhen was talking, and they were listening.

After a while, the water in the pot boiled, and there was a chug of steam from the spout.

Seeing this, Emperor Chongzhen smiled and pointed to the kettle, and said to them: "I just talked about a lot of energy, and these energies can be transformed into each other. Let me ask you a question. If the spout of the kettle is blocked, what will happen? what's the situation?"

Hearing this, it seemed very simple. Seeing the emperor's amiable expression and wanting to show himself in front of the emperor, these supervisors raised their hands one after another.

Emperor Chongzhen ordered one at random, and the student of the Imperial College stood up excitedly and replied: "Student Niu Youdao, the student thinks that if the spout of the pot is blocked, no more gas will come out of the spout!"

"..." Emperor Chongzhen didn't expect such an answer, and it seemed to be right, but it wasn't the answer he wanted, so he asked again, "Then where did you get angry?"

Hearing this, most of the Guozijian students were stunned. Aren't they all blocked and angry?
As a student of the Imperial College, they are basically from a well-to-do family.In daily life, there are servants to serve, and then go to the kitchen, so naturally I have never seen the process of boiling water.

However, both Li Dingguo and Liu Wenxiu came from poor families. During the Southern and Northern Wars, before they became the leaders of the army, they did it by themselves.Therefore, they have seen boiling water many times.

Seeing that the scholars of the Imperial College could not answer this question, and Li Dingguo was immersed in this question, he answered the question casually: "I will lift the lid of the pot and let out steam!"

After hearing this, Emperor Chongzhen glanced at him, nodded and said, "Li Qing is right, then let Li Qing plug the spout of the pot!"

Hearing this, Li Dingguo thought he had nothing to do, so he went up and put a special spout plug on the side of the teapot, and stuffed it on the spout.

Sure enough, after a while, the lid of the pot was pushed open by the steam, and the steam really came out of the lid.

So, Emperor Chongzhen ordered another prison student who looked weak, and asked him to press the lid of the pot so as not to let the lid steam.

As a result, under the watchful eyes of everyone, the supervisor couldn't finish what Emperor Chongzhen told him, so he blushed with shame, and quickly explained to Emperor Chongzhen: "Your Majesty, the student is ashamed, I don't know why, something inside is pushing the lid of the pot hard! "

Emperor Chongzhen didn't blame him, but ordered other people to feel the power of the steam, even Li Dingguo and Liu Wenxiu felt it.

Finally, when he saw that they were all surprised and waiting for his explanation, Emperor Chongzhen smiled and said: "This is energy conversion, heat energy is converted into kinetic energy, and in the middle, it involves the conversion of liquid and gas, and the molecular structure. Different, the knowledge of steam pressure. What you feel in front of your eyes is the operating principle of steam trains. It’s just that this is very simple, and there are many other knowledge used in steam trains..."

When it came to the latter, almost everyone who heard it for the first time opened their eyes wide in surprise, looked at the pot for boiling water, and thought about it one by one. After getting up, it has such a great effect!
