Huang Tun and Wu Jinggang were about to leave. A doctor of Imperial Academy who had been silent, named Niu Dun, whose courtesy name was Sitan, was about the same age as Huang Tun. Suddenly, he asked: "Envoy Huang, why do things fall from high places to low places? Is the saying that people go to high places to water flow to low places? Is it the same thing as this?"

Things fall from high to ground.

Water flows to the lower places.

This has been common sense for thousands of years, but no one has studied what causes it. After Niu Dun heard what the Dusk said just now, the desire for knowledge was opened.

He suddenly felt that what was inside was actually not boring than writing articles.

Very interesting.

At dusk, he turned around and looked at Niu Dun, "I have been studying this issue recently. If you are interested in it, I will come to you in the past few days. By the way, what are you good at?"

Niu Dun was very confident and smiled and said, "It's all-round, but there is no skill."

The dusk is happy, "It's you."

Turning around and taking Wu Jing to the Ganqing Palace.

Zhu Di only knew that Xunwu was going to study education reform with Wu Yubi, but he didn't know that Xunwu had made a math work. He instinctively thought that this might just be a school.

The school of mathematics - I'm afraid it's not a joke.

Mathematics is indeed not valued.

Just by making this school, it is impossible for him to become a big shot like Cheng and Zhu.

However, Zhu Di still met the request made by Xun.

Give Wu Jing and Jinshi.

At the same time, except for the Ph.D. in the Imperial Academy, it is just a false reputation and is not working in the Imperial Academy for the time being. After all, Wu Jing has not mastered the mathematics created by the dusk, so it is a bit unrealistic to let him preach and receive careers.

Wu Jing has no reputation yet.

Wu Jing was already confused.

He never dreamed that he could pass the Qiu Seizure and become a fellow Jinshi, and a Ph.D. in the Imperial Academy - will he be admitted to the officialdom?

The reason is because I am willing to learn mathematics with dusk?

It's simply incredible.

Wu Jing finally understood the words that people in the court were easy to do.

Leaving Zhu Di and returning to the Imperial Academy, everyone had dispersed, and only Wu and Bi and Niu Dun were left talking about something in a low voice. Seeing Huang Dun and Wu Jing return, Wu Yubi looked at Wu Jing and stood up and said, "What's wrong?"

Wu Jing smiled and was taken first by the dusk: "What else can I do? I will be with Jinshi and a Ph.D. in the Imperial Academy."

Wu Yubi shook his head, "Your Majesty is really obedient to you."

Haha, I laughed at dusk, "This is not a big deal. It's mainly because the talent is under great pressure now. It's a good thing for someone to learn mathematics with me and then promote mathematics. Of course, Wu Jing is also good."

Speaking of this, I observed Niu Dun from the corner of my eyes.

I found that this scholar of the same age heard that Wu Jing's face was still as calm as water after he was promoted, without any envy, jealousy and hatred. He nodded secretly and was the only one.

People who are engaged in learning should not have a strong sense of fame and fame.

In this regard, Wu Jing needs to be tempered again. He was happy in the Ganqing Palace before, but it was not bad. After all, Wu Jing is still young and the new crown person has not yet matured.

He said to Wu Yubi: "Yu Bi, I have a lot of things. Regarding Wu Jing's math, there are some things you need to teach me about in the early stage, mainly to let him master the new characters in the dictionary you compiled."

The dictionary compiled by Wu and Bi mainly simplifies some traditional characters and uses the pronunciation method.

This is a completely different method from the "anti-shut method".

It's clearer and clearer.

However, the initial vowels and tones of the twenty-four Chinese pinyin were taught to Wu Yubi at dusk, and Wu Yubi also mastered it perfectly. Once this dictionary is promoted in the future, Wu Yubi will be famous in history.

These letters should also be involved in mathematics, such as the sine cosine tangent cotangent.

So Wu Jing's first step is to master these letters.

Wu Yubi smiled and said, "Seriously, if Wu Jing is willing, I will recommend the dictionary I wrote. On the one hand, I can also master new dictionaries at the same time. In the future, I will also be a good assistant."

Laughing at dusk, "Okay."

Looking at Niu Dun, "You can actually learn these things with Wu Jing. For our future research, we must master things, but now... come with me."

Niu Dun thought for a while, "Please wait, I'll get the pen and paper."

A good memory is not as good as a bad pen.

A moment later, Niu Dun returned, holding rice paper and quill in his hand - because Dusk promoted quill in the era business, this thing has now become popular among the entire circle of scholars.

This thing is a powerful tool for shorthand, but the artistic quality of calligraphy is indeed unpretentious.

The two left the Imperial College.

Walking at dusk, he said, "The reason why people are human is because they are good at thinking, discovering the truth from it, and then applying it to life, thus constantly evolving. Therefore, many times, in our common common sense, there is profound principles, but we didn't expect it. The project I have recently studied, in addition to mathematics, has also taken shape, and now it needs to be verified by Wang Jinghong's return to the sea."

This time Wang Jinghong went out to sea, Zhu Di followed his own strategy and asked the Ming fleet to divide it into two groups. Starting from Suzhou, one fleet headed north and the other headed south, all following the astrological map and trying to go straight as far as possible.

This is to verify that the earth under your feet is a sphere.

Of course, there must be some "royal smuggling" activities along the way.

Scientific research and making money are both good.

However, there is a troublesome thing. Once the earth under your feet is verified, in order to ensure the divine authority of the monarch, Zhu Di must have to come up with a set of rhetoric by himself: proving that there are gods in the world, but they just don’t live on the earth.

This is not difficult.

Anyway, scholars have never believed in God in history. The power of the king is a fool to the people, and scholars do not believe it. Therefore, at that time, just talk about the theories outside the starry sky.

The universe is so big, there is always a territory of gods, such as... making up an "Asgard"?

I came outside the city and found a tree full of cherries. I smiled and said, "Once, I was sitting under an orange tree reading a book, and then my head was smashed by the ripe orange. At that time, I was wondering, why didn't the orange fall into the sky, but hit the ground?"

Niu Dun hurriedly recorded.

Standing under the tree at dusk, shaking hard, a large number of ripe cherries fell to the ground, "Look, we are all accustomed to this situation, but no one has ever thought about why it is falling rather than going upward."

He picked up a stone from the ground, threw it up hard, watched it fall, and continued: "Why does the stone we throw at the sky fall down after reaching the highest peak, instead of keeping upward?"

Niu Dun hesitated, "Has he used up all his strength?"

Dusk nodded, "The truth is this truth, but when the force is exhausted, does it also require a force to fall down by the stone? What is this force? Is it a force that makes the orange fall from the book a force? How does this force come about, and where does it come about?"

Continue to pick up the round stone, roll in the distance, watch it stop slowly, and continue to say: "Look, when we roll out a stone with force, it will stop sooner or later, that is to say, the force we use will be slowly exhausted. Think about it again, when we shoot arrows, the greater the force, the farther the arrow shoots? And the greater the force, the faster it is, the greater the power, the greater the power. Similarly, when we throw a feather out, it will not cause any harm at all, but when we throw a stone out, it will hurt people. We all know this common sense: the heavier the thing, the more painful it hits. So what is the relationship between weight, strength and speed? If we can understand this relationship, we can use this principle to do more things."

After pausing, "This is what I have been studying recently. Because it is related to force, I call it mechanics. Niu Dun. Are you willing to follow me to study this science? Of course, studying this science will not allow you to become a minister of the Six Ministry. At most, you should be a scholar. So you have to consider it clearly. Once you agree, I will give you the best conditions to verify and promote the various theorems and formulas of mechanics I proposed."

The main thing is promotion.
