The stars and the moon set in the west, and Venus can already be seen in the east.

Lu Dazhong blinked his sour eyes in the night breeze in the early winter morning. Without a little discussion, it was already a night. He is still above Zhang Zai's age and lacks energy. Although I am older, my sleep will naturally decrease, but tonight I consumed too much brain power, but my head hurt, and I felt extremely tired, far less than the endurance of young people.

"What do you think?" Lu Dajun walked beside him and asked his brother on the side.

"It's interesting." Lu Dazhong put down the hand that was rubbing his temples, "At least today I finally know what kind of tree the plums will fall on." ”

Lu Dalin said: "The theory of gravitation is just speculation, not empirical evidence, and it cannot be confirmed for a while. ”

The three Lu brothers walked to their residences together, and they didn't forget to talk about the discussion they had just discussed in Zhang Zai's study.

"Yes, it's true that Han Gang said that it may not be true...... "Lu Dazhong said to his younger brother, "but who took out the plum landing before to study?" For thousands of years, it has been regarded as a matter of course, and it has never been investigated. If Han Yukun's hypothesis can drive the world's scholarship to begin to pay attention to the knowledge of things, even if it turns out to be wrong in the end, it is already a great good. ”

"What's more, Han Gang's deduction is still very reasonable. Everything is powerless and does not move, everyone knows this, and the driver of the cart knows better than us. As for 'if you can't change, you will always maintain the current state'......" Lu Dajun said very slowly, obviously this statement made him feel very embarrassed, if it wasn't for Han Gang having mentioned it many times in his letter to Zhang Zai, he couldn't have done it overnight, "Han Gang's law can also be said to be not wrong. In winter, it is often possible to see empirical evidence, if not...... Resistance, pedestrians and vehicles on the ice should be able to slide forever. ”

"Now that this law has been confirmed, the plums on the trees will always come back when they fall to the ground and the stones thrown into the sky, and there must also be a powerful presence in them, that is, gravitation." Lu Dazhong said, "Plums and stones are just small things in front of you. The sun, moon and stars, including the earth beneath your feet...... Or according to Han Gang, the earth is maintained by gravity and orbits each other. ”

Among the three, although there were doubts about Han Gang's statement of gravitational force, they did not accept it all, and even Lu Dalin completely opposed it. But as for the astronomical theory that Han Gang was involved tonight, they did not veto it in one word.

Because Zhang Zai's cosmology is inherited from the old 'Xuanye Theory'. All things are condensed by qi, and 'the sun, moon and stars are also filled with light', and the earth is also made of qi. As for the theory that the earth is round, it has long been clearly proven, and the sky is round and the place is just wrong, and the people of insight in the Shilin have all accepted the saying that the earth is round.

Han Gang's several opinions are just the views that Lu Dazhong and them hold on a daily basis. Only the moon moves around the earth, the earth moves around the sun, and the five planets of gold, wood, water, fire, and earth are also equal to the earth, which makes them unacceptable for the time being.

However, Han Yukun's statement can explain why the five stars are retrograde. The speed of the detour varies. It's like two galloping horses, the back horse chases the front horse, and when you look back, the front horse that is being chased is equivalent to retreating. ”

"It can also explain why the two stars of water and gold have always been close to the near future and have not deviated."

Lu Dazhong and Lu Dajun sang together. Venus and Mercury are always near the sun, so Venus has two names, Qiming and Chang Gung, and Mercury is blocked from the sun's brilliance for a long time and can rarely be seen. In the past, no one explained the reason, only Han Gang, probably because of the relationship between the object, so he stared at it.

Speaking of which, although Han Gang's point of view is special and incomprehensible for a while, it can explain some astronomical phenomena that they know very well.

Lu Dazhong and Lu Dajun are both thinking deeply about this, rather than denying it.

"I really don't know how he came up with it, is there really a so-called God-given talent?" Lu Dazhong said half-jokingly.

"'Born to know' is a saint! Han Gang is still far behind. Lu Dajun shook his head. But what Mr. said about 'big heart', which is difficult for others to do, but Han Gang has done a full job. ”

Lu Dazhong laughed, if you only look at Han Gang's words, it actually involves the sun, moon and stars, it can be seen that the 'big heart' has reached the point of arrogance. It's just that as soon as he thought about it, Lu Dalin had a calm face and didn't open his mouth.

Lu Dajun walked for a while, and when he saw Lu Dalin's face, he asked strangely, "What's wrong?" ”

Lu Dalin shook his head, "I just think that the Great Dao is not here." ”

Lu Dazhong replied: "The Great Dao originally exists in all things in heaven and earth. If you want to follow the Great Way, you must understand all things. ”

"Not to mention these, the theory of Gewu is always still superficial, the three laws of mechanics have not been more empirically proven, and now what Han Gang expounded is just some fragments and simplifications, if you want to finally establish the status of our Tao, it is not possible to solve it in thirty or fifty years."

But Lu Dajun said: "I don't know if the eldest brother hasn't seen it, I always feel that Han Yukun is hiding it in this theory of things." Even today, it seems that I have only said half of it. ”

"He himself is not sure, so he can only take out what is already certain." Lu Dazhong guessed Han Gang's thoughts.

Lu Dalin sneered: "If you don't take it out for scrutiny, you still want to rely on the power of one person, and you can't deduce it all." ”

Lu Dajun shook his head.

Han Gang, who cherishes himself, is indeed a little wrong. However, when they were discussing, it was their younger brother who was arguing the most intensely. Han Gang didn't dare to casually come up with a superficial theory that had not yet been clarified, otherwise he would definitely not be able to escape questioning and accusation.

"These are actually subsections. Lu Dajun said, "I'm getting older, and my days are short." If you want to expand the lintel of the school, you can only rely on young people. ”

Lu Dalin snorted coldly, "I'm afraid that he is young and shallow, and his foundation is not deep." Talking about the road will lead astray in the end. ”

"Take your time and watch." Lu Dazhong said, "I'm waiting for me to be a senior brother, and I will often mention it in the future." Be careful not to lead him astray. ”

Lu Dalin stopped talking again. His eldest brother is too good a person, Han Gang goes to Beijing during the Chinese New Year, as long as he can be a Jinshi, he will definitely soar in the future, how can he mention him?

………………

Han Gang was lying in the guest room, separated by a thin cloth cushion, and directly below his back was a wooden plank.

There is a table and a couch in the room, and there is only one oil lamp on the table. There are no other decorations and valuables. Simple and unpretentious, this is the best and mildest adjective that can be picked out in the dictionary.

Such a simple hut, Han Gang didn't know how long it had been. For a moment, he slept uncomfortably. The pillows are too hard and the room is not clean. But he still endured it and did not show any displeasure. This is a necessary and a matter of course.

Zhang Zai didn't arrange a better place for Han Gang to live—speaking of which, there would be no guest rooms in the academy like a hotel—lying on a bed sewn with several layers of thick cloth, and the life of Zhang Zai's student in the old years came back to his mind.

Two points and one line, and occasionally three points and one line. This is all the memory of Han Gang's student life at that time.

Shaking his head to dispel the monotony and fulfillment of his student life, Han Gang was also recalling what he and his assistants had said today.

Han Gang is now trying to integrate the physics of later generations into Confucianism, and he is practicing the policy of Li Daitaozhuang, and the utilitarian heart is not unimportant. But in the conversation and discussion, Zhang Zai knew Han Gang's heart of fame and fortune, but he did not reprimand him, but only mentioned two more sentences to let Han Gang clear the source.

can become a generation of scholars. Zhang Zai's open-mindedness and vision are not comparable to ordinary people, and he is definitely an outstanding first-rate person. Han Gang took out the three laws, as well as the way of the sun and the moon, Zhang Zai can quickly understand it, and can draw inferences from one another.

Han Gang's theory was agreed upon by Jang Zai, but under Sanlu's questioning—perhaps cross-examination—he almost collapsed. If it weren't for the insistence on these truths in my heart, I would almost have to change my course.

This is the dilemma that often arises when Confucian scholars discuss the meaning of the scriptures, although the purpose is not necessarily to deny the other party's point of view, but the sharp words and sharp cuts make the ill-prepared scholars sink into the sand.

And Han Gang persevered. He insisted on preaching Guan Xue, and the subsequent difficulties and sufferings were all self-inflicted, and he couldn't blame others.

In today's Shilin, various schools of thought do not give in to each other, like a hundred flowers competing for beauty. But at the end of the day, there is only one who can earn his head.

It's a bit like the contention of a hundred schools of thought during the Spring and Autumn Period and the Warring States Period, and only Confucianism laughs the most.

Han Gang came from the memory of later generations, and the only school of thought at this time could be passed down to future generations was Cheng Zhu Lixue.

Han Gang Zhilu said that Wang Anshi was a literary master, a poet, and a reformer, but Wang Anshi's academic views on the scriptures and meanings did not exist in his memory.

As for Guan Xue, it is so pitiful that only four sentences of Hengqu have been handed down. And Zhang Zai turned out to be in the history books and became the pioneer of science.

What a joke that doesn't make people laugh.

As a disciple of Zhang Zai, and having the memories of later generations, Han Gang has the heart to change all this.

Today's discussion is just the beginning, although his reputation in the academic world is not high, but since Hengqu Siju has been born, Han Gang, who has inserted a foot in it, has already established his status in the minds of his classmates.

Peace for all generations.

Such a grand ambition makes people become enterprising, and Han Gang is indeed working in this direction.

If Han Gang can rise higher and higher, then the academy behind him, and even the officials with names and surnames, will be the main force in the school war in the future.

Commanding them, Han Gang asked himself if he could subdue them, it would be most of Sergeant Lin Qingyi who fell into his own hands.

At that time, Han Gang can be said to be that his purpose is to open peace for all generations!
