I have to say that an incredible conclusion was deduced from some normal cognitions, and all of them were calmed down at once.

At this time, hearing Huang Zongxi's question, most of the others, including those prisoners, were staring at Zhang Mingwei, and they wanted to know, there was buoyancy in the air, so what was the use of knowing this?

Zhang Mingwei saw that he was seriously seeking advice, and his tone was not so cold, and he immediately replied: "Have you ever thought about what this buoyancy has to do with and how should it be calculated?" If you know this, isn't it a big deal? ”

The scene was silent, and everyone was thinking about it. Only Zhu Yujiao's eyes are getting brighter and brighter, because at this time, she remembered the plane she saw in the documentary. What can float in the air, isn't that what an airplane is!

She wanted to blurt out this answer, but she remembered that her mother said that if she treated Zhang Mingwei as her father, she would not exceed her duty. Therefore, when I think that my father and emperor are talking to their courtiers, it seems that they should not interject. So, she held back.

Sure enough, just like she thought, she heard Zhang Mingwei say to the person in front of him: "Knowing the buoyancy in the water, this can be related to the ship, and even different materials can be used to build a ship without sinking." Because you already know the algorithm of buoyancy, you know what buoyancy is related to. For example, have you ever wondered if an iron ship is unsinkable? So what kind of iron ship will not sink? Similarly, if there is buoyancy in the air, can something like a ship be made in the air, which is commonly known as floating in the air......"

In one breath, Zhang Mingwei said a lot.

Those with lower IQs were confused by him, and I felt that what Zhang Mingwei said seemed completely impossible!

However, Huang Zongxi immediately thought of it, the iron boat, and the Kong Ming lantern, etc., after Zhang Mingwei's dialing, it really is, these things can float, if you know the secret of buoyancy, wouldn't it really be possible to achieve something that you never dared to imagine before?

Thinking like this, he felt the urge to find out the truth of the matter right away.

"Also, you should already know that there should be something in the air like water, which can produce buoyancy!" Zhang Mingwei continued to give them popular science, "So have you ever thought that it will be more difficult for people to move in the water, why is this? Does this also happen in the air, and what does this affect? ”

When he said this, the people who heard it were even more confused.

It is common sense that movement in the water is more difficult than on the ground. So why is this, no one really thinks about it, and at most it will answer that it is the cause of water. But why is it difficult to move because of water? What about in the air?

Most people, in this moment, have died I don't know how many brain cells, and for the first time I feel that my head is not enough.

Huang Zongxi was asked by Zhang Mingwei here, and he had completely forgotten to question, so he immediately made a gesture and asked sincerely: "Please also ask Mr. for advice!" ”

This one teaching, and the teaching when I first came over, are definitely two meanings, and non-Chinese people definitely can't figure out the difference.

Seeing him like this, Zhang Mingwei smiled and said: "Because there is resistance in the water, and relatively, there is also resistance in the air. You can study this resistance, and in this way, you will be able to grasp it. It can be used in many places, such as in the water, how to make the boat faster. And on land, it's how to make the buckshot go farther. ”

Speaking of this, he remembered something, so he said casually: "When I entered the palace today, I just made a proposal to Your Majesty to improve the ordnance of my Ming army, one of which is how to make lead bullets shoot farther. ”

After a pause, Zhang Mingwei stared at Huang Zongxi, and said seriously: "If there is chaos today, a little ambitious, I think how to open peace for all generations, I am working hard for it, and what about you?" ”

"Establish a heart for heaven and earth, establish a life for the people, continue to learn for the saints, and open peace for all generations", this is a classic Confucian saying, at least the scholars of the Ming Dynasty, even if they did not have it in their hearts at all, they would say this verbally.

At this time, he was suddenly brought forward by Zhang Mingwei, and a smart person like Huang Zongxi was like being slapped on the head and stopped him at once.

But at this time, Zhang Mingwei was not finished, and said to him seriously: "Poetry and song empower the world to be peaceful, and the country and the people are safe?" And those Four Books and Five Classics, the princes of the court, including you, are you not familiar with it? However, in today's world, why is there such chaos? Watching the people of the world suffer, don't you feel a little responsibility? Have you forgotten your sage ambition and the original intention of studying? ”

In fact, many ancient scholars, their original ambition was "to establish a heart for heaven and earth, a life for the people, to continue to learn for the saints, and to open peace for all generations." It is precisely because these four sentences express the heart that they will become famous sayings.

However, after many people arrive in officialdom, they slowly change.

However, these prisoners can't say all of them, at least some of them still have this kind of thinking. Because of this, under the encouragement of others and driven by people with intentions, he felt that Zhang Mingwei was a villain and became angry. Huang Zongxi is the same, so he is enthusiastic and wants to expose Zhang Mingwei's true face.

However, at this time, after a series of questions from Zhang Mingwei, they already felt that Zhang Mingwei was really very knowledgeable. They are sure that few people in today's world can answer these questions that Zhang Mingwei just said, and most people have never even thought about it.

At the beginning, I was impressed by Zhang Mingwei's knowledge, and then in the face of Zhang Mingwei's questioning, many people were ashamed when they remembered their original intention.

At least this is the state of Huang Zongxi at this time, and I saw that his face was full of shame. But in the blink of an eye, he suddenly became excited again, saluted seriously, and said to Zhang Mingwei: "After the student obtains the approval from the teacher, I wonder if the adult can guide the student?" ”

Originally, Huang Zongxi had the sprout of practical learning that had been applied to the world in his heart, but at this time, Zhang Mingwei's words revealed a world that he had never thought of before, of course, he was itching.

Among the group of prisoners, there were also a few who followed Huang Zongxi's example and asked questions. However, most people are silent, and there are even a few of them, and after coming to their senses, they will think about how to embarrass Zhang Mingwei, or it will be difficult to make a difference if they don't turn back.

However, Huang Zongxi and the others led this time have been convinced by Zhang Mingwei, even if they want to make trouble, they will attract the reprimands of their peers. Therefore, I can only do it in a hurry.

At this time, the sky was already dark, and Zhang Mingwei drove his horse to move, but at the same time said: "The people of Daming are now in dire straits, and I don't have time to teach you." If you have a conscience, you should talk less, do less tricks, and do more practical things for the people of the world! ”

When Huang Zongxi heard this, he was very ashamed, he didn't dare to stop it, and respectfully got out of the way: so knowledgeable and talented but for the country and the people, no wonder he was called Mr. by the emperor!

Looking at Zhang Mingwei's back, he suddenly felt a little unwilling, so he shouted at Zhang Mingwei's back: "Adults can give you one or two points, and you can also make the world one more person who benefits the people, and there is one more way!" ”

Hearing this, Zhang Mingwei seemed to think about it seriously, and then said without looking back: "Go home and boil water, see how the pot reacts, and see if you can realize any truth and come to me again!" ”
