Han Gang spent three days in Hengqu Town, during which he discussed with Zhang Zai and others many times the way he advocated the way of learning things. And his views on the sun, moon and stars have spread even among ordinary students.

Some of them know it in their hearts, some accept it all, but some disagree with it, and some of them are so sternly refuted by Lu Dalin.

Lu Dalin's eloquence should be regarded as very outstanding under Zhang Zaimen, and Han Gang's ability to quote scriptures is also beyond his reach. During the discussion on the first night, Han Gang tried to use his explanation of combining the principles of mechanics with Confucian vocabulary to explain the classical mechanics of later generations to Zhang Zai and others. And Lu Dalin's few words grabbed the loopholes in Han Gang's words, and pressed him to almost lose.

One is that Han Gang's own level is not enough, and what is made behind closed doors and barely screwed together cannot be as perfect as the laws of later generations after thousands of tempers. At the same time, Han Gang himself is not in a good state, he has been on the road for several days in a row, he is tired, and he stays up all night, although he is not talking nonsense, but his brain is a little slower than usual, of course, he is not the opponent of Lu Dalin, who is recuperating.

Sir Isaac is not so easy to be, Han Gang has heard of the book "Mathematical Principles of Natural Philosophy", but it is not his level to write it. The current situation is that Han Gang can deduce conclusions from everyday phenomena, but he cannot describe them mathematically accurately. Han Gang's empty words, coupled with incomplete words, made the debate that night of course a little pale. Being able to convey his views smoothly is already the result of his correspondence with Zhang Zai in the past.

And when he got up the next day, Han Gang looked back, but he scolded himself for being confused. The way of physics is not a battle of words - put the facts, be reasonable, and experiment is the first. It is not intuitive to just talk with your mouth, and it is more effective to prove your theory with experiments than to argue for three or five years.

Relying on the frozen canal and a few small objects, Han Gang easily and roughly proved the first and third laws. The second law, which requires precise measurement and calculation, although it cannot be proved for a while, has been proved by experiments, and the first two laws have been proved by experiments, which is enough to make the onlookers believe in the theory of gravitation, which is even more unpredictable.

Lu Dalin's refutation is still harsh, but it is unconvincing in the face of the facts. Prove your point of view, as long as one of them can be convincing, and the other points can be believed. Han Gang's methods are close to this. It's a pity that this is just a debate, not a scientific method of argumentation.

But winning is winning, and Han Gang can be regarded as relieved, he never thought that his hard work would have so many loopholes. If it weren't for the natural correctness of these laws, which can be verified by experiments, I would be embarrassed.

However, Lu Dalin's refutation was not without benefits to Han Gang. He attacked repeatedly, causing Han Gang to notice the loopholes in his theory. Not only can these laws be more perfected, but also have psychological preparation for the criticism that will be faced in the future, and be ready to fight back.

It's just that Lu Dazhong, Fan Yu and others, after several heated discussions, have a faint sadness in their expressions. Such an attitude made Han Gang feel a little puzzled, so he came to ask for advice. Only then did this question realize that they were worried about the discussion in Shilin.

Although people of insight can see the significance of this set of Gewu theory for Confucianism to overwhelm the two families. But people of insight are a minority after all, and literati who like to find fault and belittle each other are the ones who have a lot of volume.

Zhang Zai originally said 'the people, my compatriots', and in Shilin, some people faintly ridiculed him for being close to the Mo family. Now Han Gang's experiment is closer to the Mo family. This inevitably makes people worry about the discussion in the world. Mozi wanted the world to love both and regarded them as brothers and sisters, while Mencius refuted the theory that they had no father and no mother. is in harmony with the Mo family, this crime, Guan Xue can't afford it.

In addition, the theory of gravitational force goes straight to the fundamental heart of heaven and man's induction. Lu Dazhong once half-jokingly said that if this matter is confirmed, the astronomical chronicles in the history of the country will be greatly changed in the future, and Qin Tianjian is afraid that he will also have a headache. Moreover, Taizong once had an edict prohibiting the practice of astronomy in private. Although the law is now relaxed, it has been left behind. But if someone really wants to get to the bottom of it, it's also a troublesome thing.

But Han Gang was also out of helplessness.

Han Confucianism and Tang Confucianism rarely talked about the universe when they preached the scriptures, at least much less than the various schools of thought today. Now, whether it is Guan Xue, Lixue, or Wang Anshi's Huainan School, the first thing to say is the sky. The universe is natural first, and then human beings are concerned, rather than the previous generations of Confucians, who focus on the human world - this is also the result of opposing the Buddha. In order to match today's trend, in order to attract the attention of Zhang Zai and others, and in order to smoothly integrate physics into the study of guanxue, gravity is a must be added.

So it doesn't matter so much.

After all, it was only Lu Dafang and other disciples who were worried, but Zhang Zai himself didn't care at all. He is dedicated to the avenue, how can he care about this trivial matter?

After a few days of harassment in Hengqu Academy, Han Gang gained a lot. But looking at the urgency of the schedule, I had to resign to Zhang Zai.

Zhang Zai did not keep Han Gang, but only wrote a few letters for Han Gang to bring to his relatives and friends in Kanto by the way, and came forward to help him.

In today's imperial examination, there are not many people who go to the capital to participate in the imperial examination at Hengqumen, and there are even more scholars from Shaanxi. Zhang Zai did not forget to instruct Han Gang at the banquet: "This time I went to Beijing, not only for the exam, but also for making friends from all over the world." Yukun, your intelligence, vision, and knowledge are far beyond ordinary people, and the only thing to worry about is your pride. Being in a high position at a young age is both a good thing and a bad thing. Don't be arrogant, treat people equally! ”

Zhang Zai's earnest teachings and diligent instructions moved Han Gang and thanked him on the spot: "Thank you, Mr. for your advice." ”

Seeing Han Gang's sincerity, Zhang Zai was also very satisfied, and specially pointed out a few students who took the exam in this subject, so that Han Gang could visit and make friends when he had time.

Han Gang nodded in agreement, and said with a smile: "Actually, there are several." Chong Jianzhong is the nephew of Captain Chong, and he also went to Beijing to take the exam this time. ”

Two days before leaving his hometown, Han Gang also received a letter from Chong Jianzhong. It said that he was going to the capital to take the exam this time. I think he will live in the Tane Mansion where he is the commander of the four compartments of the Dragon Guard, and it should be easy to find him when he arrives in Tokyo. It's not like the few mentioned by Zhang Zai earlier, the city of Tokyo, with a population of one million, has no clear clues, and no one can be found at all.

Hearing Han Gang mention Jianzhong, Zhang Zai groaned.

"It's Uncle Yi's, right?" He still remembers the student in Chong Jianzhong. Don't mention the identity of the nephew of the planter, he has come to shoot willows several times in the spring, and he is always the first disciple, and his impression will never be deep, "His knowledge still needs to be honed, why did he go so early?" ”

"Uncle Yi didn't get a jinshi, but a subject of Mingfa." Han Gang explained for Chong Jianzhong, "He already has an official body, but he still wants to become a civil official, and he needs to take a background." ”。

In the old days, the imperial examination, the Jinshi examination of poetry, and the Ming Jing relied on the scriptures. Now that Jinshi has also taken the Jingyi test, it is natural that there is no more Ming Jing in the subject, but it has been changed to Ming Law, and the law is examined to judge the case. This is also Wang Anshi's reform of the imperial examination in order to professionalize the criminal name - because he is not familiar with the law, there are countless officials who have been bullied by the officials.

Although the selection of people to be transferred to Beijing officials is generally based on the examination of cases and legal decrees, so as to prevent new officials from being unable to take up such important positions when they serve as pro-people officials at the county level. However, although the rules are good, they cannot prevent the parties from complying with them.

The East Court of the Judge generally does not take this exam anymore - the selection of people can be transferred to officials, and there are all high-ranking officials and eunuchs at the road level standing behind them without exception, and no one dares to offend them - the officials who are the most reluctant to transfer to officials will still be deceived by the officials in the yamen.

Wang Anshi wanted to change this status quo, so he had Ming Fake.

It's just that although the Jinshi Branch has changed to take scholars by scriptures and righteousness, it is a good move for northern scholars such as Shaanxi. However, the cancellation of the Ming Jing Department and its replacement by the Ming Law Department is out-and-out bad news for the northern scholars.

"Ming Fa Branch." Zhang Zai shook his head and sighed, "Yukun, you go to the Jinshi examination, and those who are on the list should be able to see many fellow villagers." Just ......"

Han Gang knew what Zhang Zai wanted to say, and then took over and said: "It's just that if the Ming Jing Department is also included, in terms of the overall number of scholars, it is very likely that the number of Shaanxi scholars who can study in this department will decrease a lot." ”

Everyone in the world knows that when it comes to scriptures, the gap between the northern scholars and the southern scholars is far less than the poetry. But when it comes to the way of punishment, the northerners are still far inferior to the south.

Compared with the northerners, who have always avoided the yamen, the southerners are not so afraid of going to the yamen to fight lawsuits. Especially the people of Jiangxi, who are famous for their good lawsuits. A trivial matter in the market will be pulled and pulled to the yamen to ask for a comment, which will make the county officials overwhelmed.

Moreover, in Jiangxi Township Village Studies, the textbooks taught are often not "Analects", but "Deng Sixian" and other legal books that teach people how to fight lawsuits. Relying on the influence of customs and customs, even a ten-year-old child in Jiangxi can talk eloquently on the yamen, so that the county officials cannot get off the stage.

"Southerners are easy to litigate, but northerners are hard to reach. Where there is a litigious place, its people are often argumentative. When things don't get together, they cling to it and chatter, and they will want to make people lie down and be willing. Zhang Zai shook his head as he spoke.

Han Gang remembered that Zhang Zai didn't seem to have served in Jiangxi, and looking at his teacher's expression, it seemed to mean something...... It sounds like he's mostly talking about Wang Anshi.

Wang Anshi did have this problem, two years earlier, when the Son of Heaven and him disagreed, the Son of Heaven was defeated.

But Zhang Zai was not accusing Wang Anshi, but he should have remembered the old things and sighed. Since there was no explicit statement, Han Gang said half-jokingly: "If you cut it, you can learn it, and if you think about it, you can grind it." If you can learn and ponder in Jiangxi, you can go to all prefectures and counties in the world. ”

Han Gang crookedly used the words in the Book of Poetry to make Zhang Zai laugh.

This disciple of his can indeed speak, and he is not the kind that is smooth and smooth, and in his words and actions, the young man's sharpness is not lacking. Zhang Zai couldn't help but think of himself when he went to Fan Zhongyan to write a book.

But this student is much stronger than his own family.

After some drinking, Han Gang saluted Zhang Zai, then went out to get on the horse and said goodbye.

The fields on the side of the road are as vertical and horizontal as tic-tac-toe. There are many praises in the world about Zhou Shi Jingtian, retro sayings, Ercheng and Anshi have all talked about it, but all schools of thought are only practiced by Zhang Zai.

Emphasizing empirical evidence over words is the foundation of Guanxue.
