Wang Yuan got a list of Xinxue disciples, but did not take the initiative to contact any of them.
There's no time, and there's no need.
If you want to do big things in the future, you must have your own group, and you must have a large number of flag-wavers. But the "Xinxue Group" is too loose. Apart from creating public opinion in the future, it will be difficult to actually do anything... Well
, Uncle Wang’s inner circle is still useful.
As for the other disciples, there is a mess of everything, and their positions are actually different, but they all like to study the mind.
Wang Yangming himself knew this situation, so he only named a few names.
Among them, Wan Chao, Wang Dao, and Liang Gu were all Jinshi in the same year as Wang Yuan. In addition, they were from the same school in the same year, and they had an iron-clad alliance. Even if they were political enemies, they would not dare to kill them easily, not to mention that they could not become political enemies with Wang Yuan.
.
In addition, Mu Konghui and Wang Yuan were colleagues in the Hanlin Academy, and they were candidates selected by Wang Yangming in the provincial examination. These relationships were also tightly tied.
Wang Yangming mentioned the names of these four people, which means that Wang Yuan can make friends with confidence and support each other, and no one will take advantage of anyone.
Uncle Wang also named one person, that is Gu Yingxiang.
Before he passed the Jinshi examination, he studied with Wang Yangming on a study tour, but he did not formally become a disciple at that time, otherwise he would have been a senior disciple of the Wang family. Moreover, Gu Yingxiang and Wang Yuan have similar personalities and very similar hobbies, so they are likely to become true close friends.
First of all, Gu Yingxiang is a mathematician. Isn’t Wang Yuan also studying mathematics?
Secondly, Gu Yongxiang was not afraid of death and was promoted by quelling chaos. When he was promoted to an official in Raozhou Prefecture, the magistrate of Leping County was caught by the peasant uprising, and other officials were helpless. Gu Yingxiang stepped forward with only one old soldier.
Riding a thin horse, he slowly arrived at the rebel camp. After a while of deception, the county magistrate was rescued and the rebel army was disbanded.
Because of this achievement, Gu Yingxiang was taken care of by Zhu Hou and was directly recalled to the capital. With his background as a Jinshi and his experience as a Jin Yiwei.
The Jin Yiwei experience means that Jin Yiwei is in charge of the entry and exit of documents. Shen Lian in the movie "Xiu Chun Dao" is a real person in history. When he first entered the capital, his official position was also the Jin Yiwei experience.
Look how similar Wang Yuan and Gu Yingxiang are!
They are both disciples of Xinxue, both are Jinshi scholars, both are favored by the emperor, both are not afraid of death, they are both good at martial arts, and they all study mathematics. If we can't become friends after getting to know each other, then we are really in trouble.
Historically, Gu Yingxiang failed to return home in time for the funeral because of his mother's death. He was impeached and dismissed from office. There was a delay of many years. Because the Yunnan rebellion was not settled, the imperial court recruited him to come back to patrol Yunnan. Finally, he became the Minister of the Ministry of Punishment, and then became the Minister of Punishment.
After being excluded, he was transferred to the post of Minister of the Ministry of Punishment in Nanjing. He worked for two years and resigned after finding it boring.
…
On the fifteenth day of the first lunar month, the Lantern Festival, all civil and military officials have a ten-day holiday.
Due to the raging rebellion and the lack of money in the Ministry of Finance, a series of activities during the Spring Festival this year have been simplified.
A banquet was given on New Year's Day (the first day of the first lunar month), but no one was given. The officials went home to eat by themselves. The southern suburbs offered sacrifices to heaven and earth. It was originally planned to have Wang Yuan lead 6,000 soldiers to appear, but now there is no big scene, and only basic sacrificial etiquette is maintained. Lantern Festival
There will be no official celebrations, and the curfew will be lifted that night to allow people to entertain themselves.
On the day of Lantern Festival, Wang Yuan was just about to go out and go shopping with Song Ling'er when Gu Yingxiang suddenly came to visit.
Gu Yingxiang held a bag of gifts and said with a smile: "Xueshi Wang, if you bother me during the Lantern Festival, you won't blame me, right?"
"Brother Weixian is so polite," Wang Yuan said, clasping his fists, "My mentor mentioned the day before yesterday that I have long wanted to visit your brother."
Gu Yingxiang handed the gift to Wang Yuan and went straight to the topic: "I learned about my dear brother's arithmetic manuscript from my husband, and I really can't help but want to learn from it."
"Please sit inside," Wang Yuan said to Zhou Chong, "go to your husband's house and tell Ling'er that I want to entertain friends now and go to the Lantern Festival Lantern Market with her in the evening."
Zhou Chong accepted the order and left. Gu Yingxiang apologized: "It turns out that I wasted my time."
Wang Yuan smiled and said: "It doesn't matter."
This guy is a pragmatist, he doesn't like vain things, and he doesn't like wasting time.
Historically, at the age of thirty-five, he was appointed as the Minister of Dali Temple, that is, the President of the Supreme Court of the country. However, he refused to accept it and actually went to work as a minister of Lingdong Province because the central department could not really do anything. And because
Tianyuan Technique (equation) is not easy to popularize. When making annotations for "Measuring the Circle and the Sea Mirror", all the content of Tianyuan Technique was deleted, which was criticized by later generations of mathematicians.
When he was the Minister of the Ministry of Justice, he felt that the existing legal regulations were too complicated, so he deleted and revised the "Da Ming Law" and wrote his own "Laws and Questions and Answers" so that judicial officials could handle cases quickly and effectively.
At this moment, Gu Yingxiang took out a stack of handwritten manuscripts and directly explained his purpose: "The equation created by the wise brother seems to be able to achieve more than five yuan?"
"It should be possible, I haven't thought about it carefully yet," Wang Yuan replied.
The word "equation" comes from "Nine Chapters of Arithmetic", the first example of which is to solve a system of linear equations in three variables.
As for "Yuan", China has long had Tianyuan Technique. The three-dimensional equation can be called Tianyuan, Diyuan and Renyuan. Zhu Shijie, a mathematician in the Yuan Dynasty, also created a method to solve four-dimensional higher-order equations, which is called "Four-Yuan Technique".
After the three elements of heaven, earth and man, the concept of matter element was added.
The most interesting thing is that when the ancient Chinese made equations, they also combined the yin and yang numbers. The solution to the four-element equation is expressed like this: "With the energy in the center, the heaven element is on the bottom, the earth element is on the left, and the human body is on the left.
Yuan Yi is on the right, and matter Yuan is on the top. Yin and Yang rise and fall, advance and retreat to the left and right, interoperating and changing, and they are infinitely intricate."
The whole process is carried out using calculation chips. Those who know the basics will know that they are solving equations; those who do not know the basics will think that it is fortune telling and divination.
This thing is so complicated that it can confuse people who study mathematics. Imagine how terrifying it is to have to use calculations of different lengths to express and solve higher-order equations of four variables.
It was for this reason that Gu Yingxiang thought that "Tian Yuan Technique" was not practical, so he turned to study trigonometric functions in depth. Now that he read Wang Yuan's manuscript and saw the numerical expression of the equation, he was shocked and felt that this technique could be used.
Solve countless practical problems.
The two first discussed equations, then quickly moved on to trigonometric functions, and then combined the two.
Gu Yingxiang also used Wang Yuan's equation symbols to fully express the theorems such as sine and cosine based on his own research.
"My virtuous brother, this method can be practiced throughout the ages to gain a glimpse of the true principles of yin and yang!" Gu Yingxiang praised.
Wang Yuan smiled and said: "What does Yin and Yang have to do with it?"
Gu Yingxiang said: "The reason why the heaven and earth change divinely and give birth to all things is yin and yang. One yin and one yang interact intricately with each other, and the changes are infinite. The sage is confused by the intricate interactions and uses mathematics to measure them. So then
"The heights and depths of heaven and earth, the comings and goings of the sun and the moon, and the secrets of ghosts and gods can all be seen and known."
Wang Yuan stood up suddenly, took Gu Yingxiang's hand and said, "Listen to what you said, you and I are close friends!"
Wang Yangming's disciples of mind science are obviously an outlier. They actually want to use mathematical methods to express and measure everything in the world. They also say that as long as mathematics is used correctly, they can measure the heights of the heavens and the earth, the comings and goings of the sun and the moon, and the secrets of ghosts and gods. Damn it.
I fit in so well with Wang Yuan.
Wang Yuan no longer discussed mathematics with him, but asked Jia Chang to deepen their understanding. Therefore, he learned that this old man had once ridden alone to quell chaos, had also learned swordsmanship, riding and archery, and had a certain understanding of the art of war.
The two of them discussed more and more things, almost talking about everything, and they wanted to know each other on the spot.
When it got dark, Song Ling'er came to Wang Yuan to turn off the lights, and then made an appointment to talk another day.
