Han Dao world

Xuan Ye said that all things are transformed by vitality, not only the sky, but also the earth.

This statement makes sense in theory, but intuitively, it is difficult for people to accept.The sun, the moon, and the stars are nothing more than they can't be touched anyway.Everything in front of you can be seen and touched, and it is also said to be qi, which is hard to be convincing.

But contrary to Liu Xie's expectations, after a little discussion, both Cai Yan and Yuan Heng said that Xuan Ye's theory was more reasonable, at least more reasonable than Gaitian's and Huntian's.

Gaitian said that the biggest problem is the roundness of the sky and the ground. This point has been proven wrong. The earth is most likely not flat, nor is it likely to be square. A circle is closer to the truth.

This point does not need Huang Yi's star-stretching technique to prove it, the lunar eclipse is the most powerful evidence.

Although Cai Yong and Zhang Heng were not together for a while, they admired Zhang Heng's talent very much and studied Zhang Heng's knowledge in depth.Later, when he was living in the rivers and lakes, he saw Wang Chong's "Lunheng" in Kuaiji, and he had a further understanding of Zhang Heng's knowledge.

Using lunar eclipse to deduce that the earth is round is not only logical, but also can be verified by astronomical observations.

The lunar eclipse is caused by the projection of the earth, which is tenable.

Looking at Cai Yan and Yuan Heng's plausible words, Liu Xie was a little confused.

This speed is a bit fast.Are young people more receptive, or are they too much influenced by me?

Especially Yuan Heng, I haven't seen her for more than a year, her thinking is sharper, and her logic is more rigorous.

When Liu Xie asked, he realized that in addition to collecting materials on Goguryeo and Buyeo, they had also read a large number of classics from the Western Regions, and they were especially interested in the content of reasoning and argumentation.When they have nothing to do, the two often argue with each other. While killing time, they also exercise their debating skills and thinking.

When they learned from the newspaper in the residence that the emperor opened mathematics for the freshmen in the lecture hall in Nanyang, they also specially studied some mathematics in the Western Regions.

When they came to Nanyang this time, what they most wanted to know was the mathematics textbook compiled by the emperor, and to see how the emperor combined different arithmetic systems together.The mathematics of the Central Plains is good at calculations, and the mathematics of the Western Regions is good at proofs. They think that the two are completely incompatible.

As soon as Liu Xie heard it, he knew that they had already walked ahead of many people. They not only noticed the specific techniques, but also touched the relatively abstract principles. The emergence of mathematical theories was just around the corner.

According to his limited knowledge of the history of mathematics, Liu Hui, the founder of Eastern mathematics theory, seems to be between the Wei and Jin Dynasties.

In other words, the accumulation of oriental arithmetic has been very deep, and it has the basis for the emergence of the theory.His arrival only accelerated the process.Not surprisingly, the opportunity to develop from arithmetic to mathematics is within 30 to [-] years.

But it's a pity that he doesn't have such background.

He can solve a lot of equations, and he can also prove a lot. It is a bit difficult to rise to the theory.

He is too busy and doesn't have much time to think about those issues.

"Of the three theories, I agree with Xuan Ye's." Liu Xie brought the topic back. "But Xuan Ye said that it is counterintuitive. To get more people to approach, you must have more solid evidence. This point may eventually be implemented in metaphysics and mathematics. Only flawless reasoning and calculations can make people feel safe. People are convinced."

"Using Xuan Ye's theory as a model, recalculate the trajectories of the sun, moon and stars?"

"Yeah." Liu Xie nodded. "Can you do it?"

Cai Yan and Yuan Heng looked at each other and shook their heads in unison.

Cai Yan said: "I don't have enough astronomy and calendar, and I don't have enough computing power. I'm afraid I can't do it. Besides, Lantai has too many documents to deal with, and it's impossible for me to think about them without distraction. question."

Liu Xie thought about it, and felt that what Cai Yan said made sense.

She is too busy to devote herself to these things.

"Let's leave this matter to the Martial Arts Hall. These problems cannot be avoided when studying the star-stretching technique."

Cai Yan looked at Yuan Heng, and said: "Your Majesty, I have the responsibility of Lantai, and I can't get away from it. Ah Heng is no longer from Lantai, just helping temporarily. Why don't she turn back to His Majesty and assist His Majesty?" The paperwork may be of some help."

Liu Xie smiled, looked at the shy Yuan Heng, and understood in his heart.

What should be done, will be done sooner or later.Those who should receive will receive it sooner or later.

Now that the overall situation will be settled, the sword hanging over Runan Yuan's head can be taken back.

"Okay, you are not young anymore, you will enter the palace next autumn and winter."

Yuan Heng was ashamed and happy, and quickly bowed down to thank him.

She has reached the age of eighteen, but she has been unable to enter the palace for a long time, so she is unavoidably anxious.Now that I have the emperor's personal promise, I can finally rest assured.Father and sister can also breathe a sigh of relief, no longer have to worry about long nights and dreams.

Seeing this, Cai Yan felt a little complicated.

-

Zhou Zhong had been to Wancheng, the three princes gathered together, and the related discussions started immediately.

Liu Xie didn't get involved immediately, he deliberately kept his attitude of staying out of the matter and let San Gong discuss it first.

With Xun Yu's suggestion in front, the discussion was very lively from the very beginning.In addition to the officials of the Sangong Mansion, many people rushed over from Chang'an to participate in the meeting in different ways such as letters and suggestions.

There are great differences and fierce debates, but the opinions of Sangong are relatively unified. In principle, they agree to select scholars according to different subjects. The only difference lies in the specific methods.

For example, how to take the exam, is it a unified exam like Jizhou counties or counties, or is it taken separately according to the different conditions of each state?

What textbooks do you use?

Jizhou prefectures and counties recruited ordinary officials, and the requirements for Confucian literacy were not so high, as long as they could read and write.Their exams basically do not involve the content of Confucian classics. Even if they do, they can choose words with no ambiguity, which is relatively simple.

But you can’t do this when recruiting high-level senior officials, it must involve Confucian classics.

When it comes to Confucian classics, there will be differences in teacher's law and family law.

Someone proposed to use the Xiping Stone Classics collated by Yang Biao, Cai Yong, etc., which was presided over by the late emperor and jointly revised by several famous Confucians. It is a ready-made unified textbook, and there is no reason not to use it.

However, it was soon pointed out that although the Xiping Stone Classics are standardized, they are not in line with the current situation.

The simplest one is "Mencius", which the emperor does not pay special attention to.

Many theories of the Son of Heaven's benevolent government and kingly way come from "Mencius". Now we have to select scholars by different subjects, but the scope of the examination does not include "Mencius". Is it appropriate?

Furthermore, the Xiping Stone Classics are all Confucian classics, without practical content, and there are no mathematics, agriculture, and engineering studies, which is also inconsistent with the emperor's policy of emphasizing practical studies.If you take the test in this way, the final admission will definitely be Confucian scholars who are dead-educated.

Regardless of whether it is fair or not, even if these people are admitted, can they take on specific responsibilities?

Chapter 1085 Index Rise

Numerous officials and Confucian scholars centered on Situ's Mansion and fought with each other, but Liu Xie never showed up.

He even refused the relevant officials who wanted to see him.

He didn't plan to get involved in this matter until Situ's Mansion achieved some phased results.

I have confidence in Yang Gong and the sages, and I believe they will find a proper solution.

Liu Xie said so.

This is a great trust, but also a great responsibility.

Yang Biao felt tremendous pressure and didn't sleep well for several days.In the end, Mrs. Yuan felt sorry for him and made a suggestion.

The election is of great importance and has a far-reaching impact, so it should be cautious. Not only should the Situ Mansion go all out, but the prefects of all counties should also participate and express their opinions.Taking advantage of the birth of the emperor's son, let's call a meeting.

Yang Biao thought it was reasonable, so he wrote to the Son of Heaven, requesting the writing of counties and counties, and asking local officials to express their opinions. Those who intend to go to the court can also take advantage of the opportunity to come to Wancheng to participate in the discussion.

Liu Xie agreed.

From the initial implementation of the New Deal in Hedong to the large-scale rollout today, eight years have passed in a blink of an eye, and it is time for the counties to report on their duties and make a phased summary of the New Deal over the years.

After the official document was issued, Yang Biao sent a letter to Yang Xiu and Mi Heng, asking them to come to Nanyang as much as possible. Some things should not be put on paper, and it is easier to talk through the matter in an interview.

When Situ Mansion was in full swing, Liu Xie was much more relaxed.

In addition to handling some daily affairs and meeting officials, most of his energy was devoted to the mathematics class of the freshmen in the martial arts hall.

The math class taught by the emperor himself has become one of the hottest topics in Nanyang, no less than the reform of the electoral system being discussed.Not only ordinary people are used as talking points, but also scholars who are interested in mathematics have devoted great enthusiasm and tried their best to collect relevant information.

If they couldn't get the emperor's face-to-face instruction, they would get close to the freshmen in the martial arts hall who got the face-to-face instruction and copy their notes.

The handouts hadn't been printed yet, so they couldn't copy them even if they wanted to.

At the beginning, most people can still understand, and even feel that these questions are too simple and meaningless, and they can understand without explaining them.Later, as the problem deepened, I couldn't understand it by myself, so I had to listen to the explanations of the new students in the martial arts hall.Later, due to the different levels of understanding of the freshmen in the lecture hall, there were differences. Some people could understand, some could not, and there were even contradictions.

The debate gradually heated up.

I don’t know who it was, but Xuan Ye, who said Zhang Heng Temple was admired by the emperor, said that it may contain the essence of the emperor’s arithmetic. Countless people rushed to Zhang Heng Temple to watch and worship, or simply drew a picture and went home to study it.

The Zhang Heng Temple has become a popular tourist attraction in Nanyang with its crowds. Even people who are not interested in mathematics are willing to visit. Many parents who hope their children will become a dragon take their children to the Zhang Heng Temple to pay their respects to the former sages and get a taste of their talents.

When Cai Yan, Zhen Mi and others came to Zhang Heng Temple, what they saw was this scene, so that Cai Yan felt withdrawn.

Too many people.

"Wait a minute." Zhen Mi was a little excited, pulling Cai Yan to sit in the car, watching the crowd coming and going outside. "Among those children, do you think there will be a few great talents like Zhang Pingzi in the future?"

Cai Yan leaned against the window, resting her chin, and pondered for a moment. "A gentleman is virtuous, isn't this exactly what the emperor wants."

"In this way, 30 years later, it will be a peaceful and prosperous world."

"Why do you know that?" Cai Yan turned to look at Zhen Mi, a little arrogant.

"It's figured out." Zhen Mi laughed.

"Can this count?"

"Of course." Zhen Mi snapped her fingers and began to count. "Government and chaos, the most important contradiction is population and land. Wenjing, Zhaoxuan, and Mingzhang Shengshi of this dynasty all experienced a sharp drop in population after the war, but land was surplus, and the annexation has not yet affected the survival of the people. With the current household registration According to calculations, after 30 years, it can roughly recover to the limit that the land can carry. If we take into account the progress of agronomy and the increase in food production, the household registration may be more..."

Zhen Mi's level of Confucian classics is not as good as Cai Yan's, but she was born in a merchant and has been managing specific affairs such as Yinfang, so she is a good hand at settling accounts.A few data are put out, although they are only rough estimates, they are also well-founded, enough to support her point of view.

Cai Yan was greatly moved when he heard this.

No wonder the Son of Heaven emphasizes mathematics.A point of view supported by data is not only easy to understand, but also more convincing.

If Confucius and Mencius could do the same, they wouldn’t be able to travel around the world without accomplishing anything.

Empty talk is not as real as data after all.

If they can also list real data to prove that they can make the country rich and powerful within a certain period of time, which prince would reject them?

"You are so good at calculation, why not calculate when the emperor will march west?" Cai Yan teased.

Zhen Mi blinked. "Is Ling Shi looking forward to the emperor's westward expedition?"

Cai Yan was taken aback for a moment, and suddenly blushed. "Isn't this... the emperor's plan all along?"

Zhen Mi giggled, then raised her hand. "If there is no accident, it will be ten years at most."

“How come you see?”

"Listen to me. If there is no accident, Yizhou will become a vassal this year or next year. If Yizhou becomes a vassal, there will be no war in the Central Plains. Only Jiaozhou will be left, and Sun Ce will be in charge. The court can fully resume production , if the annual growth rate is [-]%, it will double and a half in ten years. If the annual growth rate is [-]%, it will increase by more than five times..."

"Wait." Cai Yan interrupted Zhen Mi. "Did you make a mistake, more than five times?"

Zhen Mi grinned. "Ling Shi can't believe it? You might as well do the math yourself."

Cai Yan did not believe it, but after checking the calculations for a while, she realized that Zhen Mi was not wrong, but that she hadn't thought of it.

An increase of [-]% in a year will increase by one and a half times in ten years.

An increase of [-]% in one year will not increase by three times in ten years, but more than five times.

Although she didn't know how much the imperial court's wealth increased every year, as far as she knew, the increase in Jizhou was definitely more than [-] to [-] percent.

Ten years later, Dahan's national strength will not only be restored, but may also reach unprecedented heights.

The Western Expedition is not an unattainable dream.

During Emperor Xiaowu's time, he was able to conquer Dawan in the west.Now with the emperor's ability to use troops, the Western Expedition is not as difficult as imagined.

In fact, only with the thousands of Han troops in the Protectorate of the Western Regions commanding nearly ten thousand national soldiers, together with the talents of Xun Yun, Jiang Gan, Shen You, etc., they made a great deal of trouble in the west of Congling. The water rose.

Once the Son of Heaven conquests himself, he will be able to control the situation in the Western Regions without requiring too many troops.

Most of the freshmen in the martial arts hall taught by the emperor himself will follow in the footsteps of the emperor in the future and become the main force of his westward expedition, right?

Cai Yan couldn't help but sigh, if only I were ten years younger.

"Why is sister sighing?" The car window was gently opened, revealing Yuan Heng's smiling face. "Shanyang Wang Zhongxuan asks to see you."

Chapter 1086 Guiding the maze

Wang Can took a rest today, and came to Zhang Heng Temple with some friends to relax.

He hasn't been in a good mood recently.

Although he became an official and became a writer, it was not the result he expected.Especially after seeing Zhang Song become Situ Changshi, he was even more lost.

Not as good as others, it can also be said that the emperor judges people by their appearance, and Ziyu is lost.Zhang Song is uglier than him, but he is highly valued by the emperor, which means that it is not the emperor who judges people by their appearance, but just looks down on him, Wang Can.

In recent days, he has been thinking about how to perform and try again.

Seeing Cai Yan's carriage parked aside, he guessed Cai Yan's identity after a little thought.Came over to ask, it was indeed Cai Yan, and immediately signed up for an interview.

He knew that Cai Yan was deeply trusted by the emperor, and if he could get Cai Yan's recommendation, the emperor might change his opinion of him.

He inherited half of Cai Yong's collection of books, and he was regarded as Cai Yong's disciple. This friendship has long surpassed that of ordinary teachers and students.In a sense, he is even more important than Cai Yan himself.
