Early Ming Dynasty: Turning Clouds and Rains into New Learning Saints

Chapter 254 The real meaning

After taking it out, everyone was dumbfounded when they saw it.

They always believed that the Prince Consort was going to teach a very powerful knowledge today and create something that could improve people's lives and bring about earth-shaking changes. It would also make Ming Dynasty a very powerful country.

Such knowledge must be extraordinary, right?
Fortunately, the two personal guards of the prince's son-in-law carefully brought out a burning stove and a kettle on the stove, and nothing else.

Is it related to this stove and kettle?
It's impossible, right?
Everyone, including Zhu Di, had this thought in mind.

The charcoal fire on the stove had obviously been burning for some time, and you could already see steam rising from the spout of the kettle.

Everyone was looking at it, but they didn't realize that the prince consort and what he wanted to say that was earth-shattering had anything to do with the stove or the kettle?
Zhang Yifan glanced at everyone, saw their faces, and could guess what they were thinking, but he was not surprised at all.

So, he opened his mouth and said: "My new science is to study things. Physics is actually about recognizing the laws between things and there will be no essential changes. Don't be surprised, I can tell you clearly. , this boiling kettle contains a very useful principle. If we use our brains to use it, it can bring about earth-shaking changes in our lives!"

At this point, he paused and found that everyone had expressions of disbelief on their faces, so he smiled and said: "Maybe you can't see it like this, so I'll add a small object so that you can observe more. An obvious phenomenon!”

After finishing speaking, Zhang Yifan raised his hand as a signal, and his personal guard stepped forward and stuffed a special plug into the spout of the pot.

Everyone looked at this scene with great curiosity, and everyone stared with wide eyes.

Not to mention, most of the people here are either rich or noble, or at least can afford to read. They may have seen things like boiling water, but they won't keep staring at it.

Therefore, after the eldest prince consort said this, they all stared at the kettle on the stove, wanting to see what happened.

However, the kettle has no surprising changes at all?Apart from the pot lid being pushed up and then falling down, there is no other movement?

Zhu Di stared at it for a while, but didn't find anything special, so he turned to look at his wife.Xu Da's daughter, Princess Yan, is still very smart, at least Zhu Di has always thought so.

On weekdays, I get close to my eldest sister again, maybe she can realize it!

As a result, Princess Yan saw Zhu Di looking over and understood what he meant, so she showed a little helplessness and shook her head slightly.

Seeing Zhu Di, he was a little disappointed, so he looked at his father-in-law again.

After all, my father-in-law is old enough and has seen a lot of things. Maybe he can get something out of it, right?

As a result, Xu Da glared at him when he saw him looking over.It seems to be saying: You and Yifan usually have such a good relationship, but you can't even find out and why are you counting on me?

Zhu Di turned his head helplessly when he saw it, and then looked at the other people present. As a result, he found that no one had an expression of sudden realization.

Obviously, no one is sure to realize anything?
After waiting for a while, Zhang Yifan stopped waiting and asked everyone: "Can any of you tell me, have you observed anything special? It's an obvious situation!"

Hearing this, a young man suddenly stood up and asked with a hint of uncertainty: "Teacher, did the lid of the pot move after the water was boiled?"

Zhang Yifan listened, nodded and said, "That's right!"

Upon hearing these affirmative words, many people couldn't help but started whispering.

"I also discovered this. If I had known earlier, I would have answered it!"

"Yeah, he took the lead and showed his face!"

"But what's so special about this? If it wasn't, wouldn't it be embarrassing?"

"..."

There was a bit of noise in the courtyard. Zhang Yifan stretched out his hands into palms and pressed them down slightly to signal. Suddenly, the courtyard immediately became quiet.

Then, Zhang Yifan said: "If this is the only answer, I believe none of you can get a useful conclusion. Okay, what's your name?"

When the young man heard this, he was immediately happy that his name would be known to his mentor, so he quickly and respectfully replied: "The student's surname is Wang, his given name is Quan, and he is also Quan!"

Zhang Yifan had no impression after hearing this. He should not be a person named in history books.So, he ordered: "Okay, come up."

Zhang Yifan didn't know that this royal power was actually left in history.

In the original history, Zhu Yuanzhang reopened the imperial examination, and Wang Quan won the Jinshi. He was renamed Wang Pu by Zhu Yuanzhang, who had the same name as the escaped general in the late Ming Dynasty, and was awarded the official position of Shizhong.

This Wang Quan was a very serious person with an upright personality. He argued with the emperor several times and refused to give in.

Finally one time, Zhu Yuanzhang became angry and ordered him to be killed.When he arrived at the place of execution, he recalled him and told him, "Have you changed your mind?"

As a result, Wang Pu actually replied: "Your Majesty does not regard me as unworthy and promotes him to the imperial censor. Why do you torture and humiliate me so much? If I am not guilty, why do you want to kill me? If I am guilty, why do you want to keep me alive? Today I am only I want to die quickly.”

Just like that, he refused to admit his mistake and asked Zhu Yuanzhang to admit his mistake. Naturally, he succeeded in angering Zhu Yuanzhang and executed him.

Back to the topic, after Zhang Yifan asked, others were still hesitant just now, fearing that the wrong answer would leave a bad impression, but in the end he answered anyway. Given his character, it was actually not surprising at all.

At this time, Wang Quan stepped forward and reached the podium.At this time, he was a little more green, after all, he was still young.Standing on the podium, Wang Quan had a serious face and stood respectfully, waiting for his mentor to speak.

Everyone below was also watching them, wondering how the prince consort could further reveal his knowledge.

Zhang Yifan looked at his student, who was probably about the same age as him, and said with a smile: "Try pressing the lid with your hand."

After he finished speaking, the guard next to him stepped forward and handed over a wet wipe, obviously to prevent the lid from burning his hands.

After Wang Quan heard this, he took the wet wipe without thinking, then went over and carefully pressed the lid of the pot.Zhang Yifan looked up, glanced at everyone in the courtyard, and reminded: "What do you think will happen next?"

Hearing this question, whispers suddenly sounded in the courtyard.

They were all discussing in private, but no one dared to stand up and formally answer the prince's words.

Zhu Di and others, because of their identities, would feel even more embarrassed if they said something wrong, so they couldn't answer.

Finally, after a long while, just when Zhang Yifan was a little disappointed, a girl stood up in the area where female students were and replied: "Teacher, the student thought that the lid of the pot might not be able to hold down!"

"Oh?" Zhang Yifan was immediately interested and asked: "What's your name?"

When the girl heard this, she immediately replied without hesitation: "The student's surname is Zhang, his name is Hongqiao, red is Hong, bridge is Qiao!"

Generally speaking, it is not good to ask a girl's name directly.However, Zhang Yifan is a teacher, so there is no need to worry.The only thing that might make it difficult for girls is to say their names in public.

But it was obvious that the girl named Zhang Hongqiao had no scruples. (Actually, Hongqiao is her own nickname, and her name is not recorded)
She also left her name in history, saying that she was smart, talented and famous since she was a child.The local gentry vied with each other to get married to her, but Hongqiao refused and only wanted to marry a gentleman with outstanding literary talent.

Such people will naturally have fewer scruples that ordinary women have.

At this time, after Zhang Yifan heard her words, he remained calm and just said: "Okay, let's see if the situation will be as Zhang Hongqiao said!"

There is no clear affirmation, which makes many people less envious. What if it is wrong?

Everyone in the courtyard finally turned their heads to Wang Quan, wanting to see what was going on?
After a while, Zhu Di looked at the expression of the student named Wang Quan and saw that he seemed to be exerting force.

Sure enough, after a while, Wang Quan saw that although Wang Quan was pressing the lid with his hand, the lid was still exposed for a moment, and a puff of air came out, and then Wang Quan pushed the lid back again.

That is to say, the girl named Zhang Hongqiao was right.

But even if such a phenomenon was discovered, no one expected it to be such an amazing knowledge.

Zhang Yifan hadn't finished speaking yet and had no other instructions. The courtyard continued to be quiet, still watching Wang Quan pressing the lid of the pot.

After a while, it was discovered that the lid of the pot, which was pressed down by Wang Quan, was exposed again, and then was pressed back again.

After seeing this situation, Zhang Yifan showed a slight smile and said, "It's ok, don't press it anymore!"

After hearing this, Wang Quan withdrew his hand, first returned the wet wipe to Zhang Yifan's personal guard, then stretched out his hand to wipe his forehead, probably because he was sweating, and finally stood with his hands down and listened to his teacher's teachings.

He heard Zhang Yifan ask him: "You didn't press the lid just now, why?"

When Wang Quan heard this, his face turned red. He seemed a little embarrassed, but he still answered honestly: "Returning to my teacher, there was a force in the pot that kept pushing against the lid. The student accidentally didn't press the lid firmly, and a crack leaked." !”

"Are you weak?" Zhang Yifan asked again after hearing this.

After hearing this, Wang Quan hesitated for a moment before replying in shame: "Replying to my teacher, the student is usually neglectful in archery, so I still ask my teacher to punish me!"

The six arts of a gentleman are etiquette, music, archery, charioteering, calligraphy, and numeracy.Most of the time, Confucian scholars lost their archery and imperial skills, but generally they did not in the early days of the founding of the country.After all, in troubled times, if you don't exercise, you won't be able to escape!

After hearing what he said, Zhang Yifan didn't say anything, but turned to look at the others and asked: "Whoever thinks he is strong can come up and try?"

After hearing this, none of his fifty students dared to stand up and try.Because they heard it, it seemed that the pot lid was difficult to press. It would be embarrassing if it failed to hold down after pressing it.

Seeing that no one was going up, Zhang Yifan looked at Zhu Di, who always showed off his strength in front of him, and said, "Someone is always proud of his own strength, why don't you come up and try? I bet you can't hold it down!"

The stopper on the spout was specially made, and the kettle was being heated and there was heat. He didn't believe that Zhu Di could hold down the lid.

Because the larger the lid, the harder it is to press it. The steam inside will try its best to escape. Because it is hot, you can only press the wooden plug in the middle of the lid that is easy to lift. The force will be uneven and it will be easy to Let the lid leak from the side.

When the people in the courtyard heard what the Prince Consort said, they followed his gaze and knew immediately that the Prince Consort was talking about King Yan.

If it were anyone else, they would probably laugh at it.But the prince consort can talk about King Yan, but they dare not.

Zhu Di was provoked by Zhang Yifan in front of the public, and he was so angry that he glared at Zhang Yifan, knowing that Zhang Yifan was taking revenge on him.

But in the end, he still didn't accept the challenge.Because he is wise and does not fight uncertain battles.As for whether he will give it a try after returning, I don't know.

Seeing that Zhu Di didn't answer, Zhang Yifan turned to look at the others and said with a smile: "After class, you can all go back and try it. The strength inside is very strong. So there is a question, where does this strength come from? What? Why is there so much strength?"

At this point, after he paused, he did not end there, but continued: "Once you understand how this force is generated and under what circumstances it will be so strong, then the question arises, this force , how can we use it? Use it where we want this force to have an effect? ​​"

After finishing speaking, Zhang Yifan thought for a moment and finally concluded: "I don't want me to tell you what it is, but I need you to think about this issue rationally based on the physics I taught you. This is A way of doing things is not only suitable for the current situation, but will be very useful for any situation in the future. Remember, it must be well-founded!"

At this point, Zhang Yifan felt that he had said enough. If he continued, he would be telling them directly.This is not a way to cultivate talents. The train of thought tells them that they should think for themselves and think logically, which is the real meaning of the lesson he taught today.

After he finished speaking, everyone looked at the kettle on the stove, looking thoughtful.

"Tomorrow, I'm still here. I hope to hear some good opinions!" After Zhang Yifan finished speaking, he took his wife and children and left.

The students in the courtyard all stood up respectfully and waited for him to leave. Then, not many people left. They all stared at the stove and kettle left on the podium, as if they were staring at the future!
When class was about to start the next day, Zhu Di and others came unexpectedly again.Needless to say, I still couldn't figure out the doorway after I went back, at least I couldn't make any rationale, so I came back to listen again.
