Chapter 1,203 Si Tianjian

Li Qiande, the king of Jiaozhi County, stated that he had graduated from the Royal Institute of Technology and was not willing to live on His Majesty's salary. He was willing to participate in the lock-in examination, or the emperor would not give him a job, so that he could serve the Emperor and Song Dynasty.

In addition, Jiaozhi scholars Tao Zongyuan, Liang Yongjin, and Ruan Wenbei have passed the examination and are waiting for the Jinshi examination.

Because the road is too far and the luggage they carry is not enough, I want to invite them to live in my palace, take care of their food and clothing, and make it easier for them to study.

Zhao Xu showed his magnanimity this time and actually agreed. He also rewarded Li Qiande with five hundred taels of silver and ordered him to buy clothes and books for the Jiaozhi scholars.

At the same time, he agreed to Li Qiande's request, encouraged Li Qiande to take the exam, and told him not to have any psychological burden. It didn't matter even if he failed the exam. He would study with Chen Zhaoming for a few more years, and there would be job arrangements.

The current path of the Qian family in Qiantang is the path of the Li family in Jiaozhi in the future.

Judge Si Tianjian, Chen Zhaoming of the Royal Institute of Technology entered the memorial. Si Tianjian’s astronomical instrument, the giant telescope, has been repaired. The ancient Yangsui, made by Su Yi and Wang Yanbi, has been completed and can be used to make fire.

This is a great ritual vessel. It is recorded in "Zhou Li Qiu Guan": "There is a Xuan man who uses a sky flint in his palm to draw fire from the sun." There is also a record of "a Yang flint on the left and a wooden flint on the right." This shows that at that time there were already officials responsible for making fire with Yang Sui.

"Zhou Li·Shu" explains: "The essence of the sun is taken from the sun, and the fire is taken from the sun, so it is called Yang Sui; the fire is taken from wood, and it is called Mu Sui."

The ancients were very particular about making Yangsui by combining hardware with it during the Dragon Boat Festival.

The Song Dynasty inherited the virtue of fire. If this ritual can be restored, jujube wood will be used to make fire in the palace on the first day of the year. It can be regarded as a relic of the ancient Zhou ritual.

If the ancient ritual of using Yang Sui to make fire could be restored, it would be a big deal, especially since this object was made by two teenage boys from the Song Dynasty. This is even more proof that the Wende of the Song Dynasty was in harmony with the heavens. Great auspiciousness.

Because of this, Zhao Xu specially postponed the schedule of accepting the rituals and music for a day, ordered Su Song, Su You, Shi Wei, Chen Zhaoming, younger sister, and Princess Shu to accompany them, and he took Empress Xiang and Zhu Concubine to inspect Si Tianjian.

Apart from the fact that the weather was a bit wrong, this was the pattern of escorts, and the auspicious events had been frequent recently, and they were all related to Su You. Zhao Xu was in a good mood, so he accepted this favor.

The courtiers such as Wang Gui and Cai Que were extremely jealous. Cai Jing even asked Su You in a roundabout way if he could take him with him, but Chao Buzhi couldn't stand it and dragged him away.

But Su You was so busy now that he really had no leisure time. If he hadn't wiped the butt of Bian Guan, the troublemaker, Su You would have refused.

Yuanfeng's restructuring was a major initiative that Zhao Xu took personally since he came to the throne. It was equivalent to Zhao Xu's political declaration of independence and was even more important than Wang Anshi's reform.

Logically speaking, the voice of opposition would be huge, but with Su You escorting him behind the scenes and using a louder and more upright voice, no sound could be heard in the suppressed court.

Moreover, this kind of suppression is all-round, starting directly from rituals and music, astronomy, history, and civilization, and extending step by step to culture, official system, military system, legal system, and public opinion... the great righteousness is firmly grasped in the hand.

Compared with Wang Anshi who was forced to have no choice but to issue a decree from Sinong Temple and implement the new law, Zhao Xu's approach can be said to be the most orthodox and correct procedure that a Chinese monarch can achieve.

After Yuanfeng was restructured, Si Tianjian also had to change his name to Taishi Bureau.

With various new theories and new observation instruments gradually taking over the mainstream, Si Tianjian has made great achievements in recent years, from calendars, historical chronological astronomical calculations, to clocks, to the theory of heliocentric theory.

Su You proposed the method of selecting Si Tianjian officials through private recruitment and examination, which allowed the Song Dynasty to obtain countless talents in mathematics, astronomy, and calendars.

In addition, the establishment of the data archives has broken the control of astronomical data by those who were taught by Si Tianjian Enyin. Coupled with regular grinding, skills assessment, paper review, task performance and other methods, Si Tianjian Enyin has been able to

The technical level of Tianjian officials has undergone a qualitative leap.

Today, the main functions of Si Tianjian include observing astronomy, developing astronomical instruments, compiling and correcting calendars, surveying and mapping, predicting floods, researching mathematics, and deducing astronomy.

Several major topics today include calculating past solar and lunar eclipses, calculating the orbits of the five planets, determining accurate historical chronology, miniaturizing clocks, etc.

Chen Zhaoming attached great importance to mathematical theoretical research. Today, Si Tianjian has reached the threshold of later university mathematics and established special research groups on limits, calculus, spatial analytic geometry, series, etc.

Chen Zhaoming and Su Xiaomei themselves have already begun to explore the matrix.

In "Nine Chapters on Arithmetic" written in the early Eastern Han Dynasty, the separation coefficient method was used to represent a system of linear equations and its augmented matrix was obtained. The idea of ​​using it as a tool to solve linear equations has been discussed by previous people.

In the elimination process, the calculation techniques used such as multiplying a certain row by a certain non-zero real number and subtracting another row from a certain row are actually equivalent to the elementary transformation of the matrix.

But at that time, there was no concept of matrix as understood by later generations. Although it was in the same form as the matrix of later generations, at that time, it was only used as a standard representation and processing method for linear equations.

After conducting systematic theoretical research on determinants, Xiaomei first introduced determinant theory in order to solve the problem of focus calculation in optics.

Later, he used determinants as a tool to solve linear equations. Together with Chen Zhaoming, he studied a set of linear equations that illuminated a sphere through a set of five incident lights and determined the focus and spherical radius through the law of reflection. The research proved that the equations

The coefficient of is related to the existence and uniqueness of the solution of the system of equations.

This is actually the famous Clem's law in advanced mathematics before Su You traveled through time. The primary matrix theory was gradually developed.

It was precisely because of the importance of this theory that Chen Zhaoming reported the success of the memorial to Yang Sui with great joy.

However, it is purely overthinking to show the pretty eyes to a blind man and expect Zhao Xu to understand this. What Zhao Xu saw was the huge political significance contained in this thing.

Si Tianjian was in the north of the city. Su Song, Su You and Chen Zhaoming had been waiting at the door early, while the younger sister and Shi Wei were sitting quietly in the capital hall inside, waiting to welcome the female family members.

The emperor's inspection was a very troublesome matter. Moreover, Zhao Xu seemed to have a seizure and even brought the queen and concubines. If it had been during the Renzong period, they would have been sprayed with blood.

But now, except for Wang Anli's objection, the court hall was quiet and not a single person came out.

Today's Sitian Prison, the place Zhao Xu wants to inspect has been put under martial law. The staff in the prison are locked in their own rooms and are not allowed to go out at will. Several gates are guarded by the new army who are watching eagerly.

At the right time, Zhao Xu's car arrived.

Su Song led Su You and Chen Zhaoming forward: "I and others, please greet your Majesty."

Zhao Xu was very interested. He watched Si Tianjian and his wife enter the gate of the big courtyard. The four characters "Towering Wuyun" on the large horizontal plaque hidden by the towering ancient cypress trees said: "This is my first time coming to Si Tianjian. It turns out that

The plaque on the door is the handwriting of Taizu. By the way, are the descendants of the Miao family still in Sitian Prison?"

Su You secretly cursed in his heart, I don't want to come to Si Tianjian. The emperor just got off the bus and it was such a sensitive topic. This guy Bian Guan is really cheating.

Su Song was also familiar with the allusions of the Six Dynasties, and his heart was pounding.

Chen Zhaoming, on the other hand, looked calm: "The descendants of Zheng Miao Changyi, the first Si Tianjian of the Imperial Song Dynasty, are no longer alive, but Miao Xun's great-grandson Miao Ke is now studying at Si Tianjian."

Zhao Xu looked at Su Song and Su You, who had earthy faces, and couldn't help but laugh: "It is better to be as pure as Jingrun in order to be a scholar. Once you enter officialdom, it will be difficult to do scholarship..."

Su Song and Su You both said yes and respectfully invited Zhao Xu into Si Tian Prison.

There is too much information here.

There were several aristocratic families in Sitian Prison in the Northern Song Dynasty, one was the Miao family and the other was the Zhou family.
