I'm sure of the prosperous age of Kangxi and Qianlong!

Chapter 430 Tianyuan Technique

Galdan Celing stayed in Nanjing for half a month, and finally waited for the imperial edict from the Ming Emperor:

The emperor of the Ming Dynasty canonized Cewang Alabutan as the Great Khan of Junggar and granted him the Golden Seal of Khan.He also canonized Nanjiang Hezhuo Danier as the Yarkand Great Hezhuo, and also granted Hezhuo the golden seal.Jungar Khan gave him a royal golden sword, a matchlock gun, and a royal colt (a gelded Marwar horse).

The emperor granted Yixi Gyatso the title of emperor and stipulated that the current emperor of the snow area, Gasang Gyatso, would be a pseudonym. From now on, the emperor of the snow area must be canonized by the Great Tomorrow Dynasty before he can be enthroned.

Luobuzangdanjin was also canonized as the Great Khan of the Snow Region and given the title Yifa Gongshun Khan.

Galdan Celing was very happy to be canonized by the imperial decree, because the Chinese emperor's canonization of Junggar meant that the two countries had formed an alliance, and the task assigned to him by his father Khan to form an alliance and recruit troops was completed.

And the great emperor of China seems to hate those Russians, which is great. The great emperor of China is really much better than those Manchu Tatars.

yes!It's much better. Zhu Yijiong, the great emperor of the Celestial Dynasty, is looking forward to his father's death soon!

Zhu Yijiong's imperial edict and canonization has indeed allowed Junggar to benefit a lot and earn righteous status, but at the same time, this status is too much.

As long as Cewang Alabutan dies, the entire Junggar region will be in chaos, and Luobuzangdanjin will have to fall out with the Junggar tribe first.Even if Luo Bu Zangdanjin doesn't cause trouble, Zhu Yijiong still has to instigate them to turn against each other. Since Ming Dynasty has the name of legal system, it can naturally operate at will.

Moreover, Luobuzangdanjin himself did not want to listen to the Manchus and wanted to rebuild the Heshuote Khanate.

Cewang Alabutan’s control model of the new territory is completely different from Galdan’s. Galdan set up a puppet, while Cewang Alabutan directly controlled it. Even if he was forced to join forces with local forces under pressure, he still wanted to control the new territory. Their descendants were all sent to the capital of Junggar under house arrest.

Galdan Celing, the most powerful man in the northwest, left Nanjing with the imperial edict and gifts, completely unaware that the entire Junggar region would be shattered in the future because of his trip.

As for Yixi Gyatso, this young lady was kept in Nanjing as a guest, specially for the emperor to consult the Buddhist teachings in the snowy area.

This is a plan discussed by the cabinet. Historically, the Manchus also did this. This is not a coincidence, but a corresponding strategy made after careful study of the complex religious regime systems in the Snowy Region, the Western Regions, and Qinghai.

In another time and space, a large number of police stationed in Beijing was also a major feature of the city of Manchu and Qing Dynasty. It was even ranked among the "Four Big" during the Daoxian period. The Manchu and Qing emperors also sent police stationed in Beijing to regent the snowy areas many times. One of them, Zhangjia III, was a classmate of Qianlong.

……

In the spring of the sixth year of Jianwu Period in the Ming Dynasty.

Galdan Celing and Ma Guangyu did not celebrate the New Year in Nanjing, but had already left Beijing and returned.

Liu Tongxun, Chen Hongmou, and Gao Dengju had been working in the Secretariat for a year and were sent to Liaodong Town as officials at the end of last year.

Among them, Chen Hongmou was appointed as the magistrate of Fushun, Liu Tongxun became the magistrate of Kaiyuan, and Gao Dengju went to Gaizhou to take charge. Gai County has been officially changed back to Gaizhou.

Among the three cities, Fushun is the front line of the war, Kaiyuan is a border town in Liaodong, and Gaizhou is a strategic town. It is hard to say whether they attach great importance to it or assign it to the frontier.

However, these three people are very motivated, not only because they are all young people, but also because they are the first batch of top scholars in the real sense three years after the restoration of the new dynasty.In order to be able to make contributions to the new dynasty in the future, I can still bear the bitter cold now.

Moreover, although Liaodong is bitterly cold and remote, it also means that it will be easier to achieve political achievements.

Zhu Yijiong, the Ming Emperor, has left an image to his ministers as a wise emperor who values ​​pragmatism and hates corruption and malfeasance. Naturally, ministers must take the right medicine.

From a practical point of view, this is certainly a good thing, because the civil and military officials of the entire dynasty valued facts and did not talk about empty heads.

During the New Year festival, Nanjing is decorated with lanterns and colorful decorations to celebrate the New Year.

The newly established Calendar Astronomy Hall of the Daming Academy of Sciences was noisy, and the entire hall was filled with the sound of abacuses crackling inside and outside.

"Clap clap clap clap..."

"call!"

Mei Yingcheng exhaled. He had just finished typing out the abacus for the last time, jotted down the data, and checked the calculations by himself. He finally said: "Sure enough, Tian Yuan Yi is borrowed from the root prescription. The two are indeed the same."

"Indeed, I didn't expect that even the Western barbarians would have such different approaches and similar approaches." Ming Antu was also amazed.

This guy is a Mongolian. His main research is trigonometric functions and pi. He is the author of "Shortcut Method for Cutting the Density of a Circle".The Qing Dynasty abandoned him when they evacuated Beijing. Fortunately, he survived and followed him to Nanjing. Now he is also working in the Lishu Astronomical Association.

On the side, Chen Mianshi, who was assisting in the calculation, said excitedly: "Two gentlemen, Tianyuan Technique has been lost for a long time, and now it has finally seen the light of day."

This is the son of the great mathematician Chen Wance, and he is accompanied by his cousin Chen Liangshi. Historically, these two men also received Chen Wance's full support and became a political party.

As for Chen Wance himself... he is now an official in Guangdong. This great mathematician still prefers being an official to teaching mathematics.Mei Yingcheng shook his head: "Tian Yuan Shu has never been lost, it's just that we never knew it and made a mistake. Unexpectedly, this Western Yi people also have such true knowledge and insights on this path. We really shouldn't underestimate the world!"

Chen Liangshi stood up at this time and said: "Sir, since the Tianyuan Technique has been solved, I should report it to Your Majesty immediately."

Mei Yingcheng smiled and said: "There is no rush, let's eat first! It's getting late. After eating, you all will work together to check it again. After making sure it is correct, I will report it to Your Majesty."

After that, he stood up and looked around the room, saying: "Although you call me sir, I can't control myself. The reappearance of Tianyuan Technique should be the result of your joint efforts."

"Sir, your words are serious." Everyone present stood up quickly, all looking solemn.

……

A few days later, Mei Yingcheng came to see the emperor.

Zhu Yijiong always gives preferential treatment to the Academy of Sciences. Whether it is Dean Huang Wu or the curators of the following museums, they can visit them at any time, and they will never be left hanging.

"Did Mei Qing make any new discoveries?" Zhu Yijiong said with a smile.

Mei Yingcheng said: "Your Majesty, please order that the Calendar Astronomy Hall will recalculate and edit the "Earth Mirror for Measurement of the Circle" and "The Jade Mirror of Four Elements"."

Zhu Yijiong looked confused because he had never heard of what these two books were or what they were about.

When Mei Yingcheng saw the emperor's confusion, he realized it instantly and quickly explained: "Measuring the Circle Sea Mirror" and "Si Yuan Jade Mirror" were both written by the Mongolian Yuan Dynasty, written by Li Ye (not Li Zhi) and Zhu Shijie. The former said The latter refers to Tianyuan Technique, and the latter refers to Four Yuan Techniques, both of which are calendar classics."

Zhu Yijiong was even more confused: "What are Tianyuan Shu and Four Yuan Shu?"

Mei Yingcheng was also a little confused. The emperor didn't understand mathematics at all!He actually doesn't even know the Tianyuan Technique and the Four Elements Technique.

To put it bluntly, Tianyuan Technique is actually not complicated. In layman's terms, it is an algebraic equation, that is, a quadratic, cubic...high-order equation of one variable, and Quaternary Technique is an advanced version of Tianyuan Technique.

how about it?
Are you surprised? As early as the Yuan Dynasty, my country had already worked out the one-dimensional higher-order equation, more than 500 years earlier than the West.

It's a pity that Li Ye is from Jin and Zhu Shijie is from Dadu, so Tianyuan Technique was naturally lost.

It was not until Mei Yingcheng studied mathematics intensively that he discovered that the European root-square ratio was similar to the Tianyuan technique.Only then did he get inspiration from it, and through constant verification, he finally reinterpreted Tianyuan Technique, and wrote "Chishui Relics" to discuss and prove it.

After Mei Yingcheng explained in detail, Zhu Yijiong finally understood that the sense of déjà vu was too strong. Isn't this Tianyuan technique just a quadratic equation of one variable?

It turns out that algebraic equations already existed as early as the Song and Yuan Dynasties, and he thought they must have only appeared in modern times.

Zhu Yijiong was well aware of the significance of this Tianyuan technique to the development of mathematics, and immediately said: "Draft an edict immediately! Order the Calendar and Astronomy Hall of the Academy of Sciences to re-edit the "Measuring the Circle Sea Mirror" and "The Four-Yuan Jade Mirror", and make this Tianyuan The root prescription will be published together in the latest issue of "Da Ming Yue Bao", and future ones will also be published together for circulation to the world."

"The minister obeys the order."

The secretary hurriedly drafted the edict, and Meng Yan, who had been reading idly at the back, also quickly picked up a pen and wrote down some daily notes. The two of them glanced at His Highness Mei Yingcheng at the same time.

Zhu Yijiong asked again: "In addition to Tianyuan Technique, does Mei Qing have other results?"

Mei Yingcheng replied: "Reporting to your majesty, the circle-cutting technique created by the guild hall's Ming Antu bachelor also successfully analyzed nine pi formulas."

"Cough cough..."

Zhu Yijiong almost choked, and even the pi came out: "I remember this Ming'an map, it seems to be Mongolian. Sure enough, there are so many talents in this world!"

Mei Yingcheng complimented: "This is all due to your Majesty's keen eye and eclectic approach. This is why we have so many talented people in Ming Dynasty, astronomy and calculus."

"Haha." Zhu Yijiong said with a smile, "Please submit the list of people who participated in the verification this time, as well as the other calendar results! I want to take a closer look."

Mei Yingcheng was well prepared and personally handed over a list of memorials: "This is the list of people who participated in Tianyuan Shu, as well as the list of pi of Ming'an Tu Scholars. Please review it."

Zhu Yijiong nodded: "I will take a look, and the Calendar Astronomy Hall will continue to work hard."

　Before the Song Dynasty, mathematicians had to formulate an equation. For example, Wang Xiaotong in the Tang Dynasty used geometric methods to formulate cubic equations, which often required superb mathematical skills, complex derivation and a lot of written explanations. This was a very difficult task.With the development of the multiplication method founded in the Song Dynasty, there was a perfect method for solving equations, which directly promoted the research on the method of formulating equations. As a result, another outstanding creation of Chinese mathematics - Tianyuan Shu - appeared.
