When Dai Yan was in this Jixia School Palace, he had not been in his courtyard for more than an hour, and he followed his entourage to report the visit. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Dai Yan personally went out to greet him, and found that the person who came was Zou Yan, a bachelor under the rank who had failed to debate with him.

As soon as Zou Yan saw Dai Yan, he saluted him, and said with a respectful attitude: "Zou Yan has seen Yanzi under the door!" ”

In the country of Qi, for learned and talented people, it is customary to add a "son" to the end of their names to show respect. Zou Yan not only used honorific titles for Dai Yan, but also regarded himself as a disciple, which Dai Yan couldn't bear.

He hurriedly avoided Zou Yan's salute and said to him, "Why is Zou Zi so polite? You and I are both undergraduates, and you are older than me, and you have spent more time in this palace than me. How can I afford to be a disciple of me? ”

Zou Yan insisted and said, "Childe doesn't have to be like this. Your knowledge is far more advanced than mine, and it is more than enough to be my master. After speaking, he pointed to Dai Yan and said to a group of scholars behind him: "This is Song Gongziyan, who proposed the heliocentric theory, his knowledge is unfathomable, he knows astronomy and geography. I am also very inferior to Gongziyan, if you have time, you can come and listen to Gongziyan's teachings! ”

Speaking of which, the reason why Zou Yan did this, as the grandmaster of the Yin and Yang family, personally visited Dai Yan and let his disciples follow, was mainly because after he returned from the debate with Dai Yan, he thought about it carefully, and felt more and more that the astronomical model told by Dai Yan was the truth, and his theory of the five elements of yin and yang was a fallacy.

The current theory of the five elements of yin and yang is different from the doctrine of later generations that are entangled with the divine stick, and the theory of the five elements of yin and yang today is actually a very pragmatic doctrine. Most of the people who study the five elements of yin and yang, which is related to the operation of heaven and earth, come from the Taishi and Taishi of various countries. And their quest for truth is not something that can be stopped by a mere face.

Taishi was a prominent official position in this era, they were in charge of drafting documents, ordering princes and doctors, recording historical events, compiling historical books, and taking charge of important matters such as national classics, astronomical calendars, and sacrifices.

Because they need to record history, write history books, and they think that what they are recording is the truth, so they are proud of their work. And they also have a very strong spirit of pragmatism, and in order to implement this spirit, they even dare to defend the Tao with their own lives!

During the Spring and Autumn Period, Cui Zhu, a powerful minister of Qi, was furious because Duke Qi Zhuang had fornicated with his wife, and he also rewarded Cui Zhu's wife with a special green hat to others, so he killed Duke Qi Zhuang when he had another affair with his wife. The Taishi of Qi has faithfully recorded this history: Cui Zhu killed the king. For Cui Zhu, this matter was the fault of his monarch Qi Zhuang Gong, Qi Zhuang Gong and his wife fornication, which was too insulting to him, and he was forced to kill the monarch. Therefore, he asked Taishi to change it and not to record this history truthfully. And threatened that if he didn't comply, he would kill Taishi.

For Taishi, writing a distorted history is more uncomfortable than losing his life, so he decisively refused Cui Shu's request, and as a result, he was killed. Later, Cui Shu found Taishi's son to see how he wrote this history. Taishi's son still truthfully recorded this history: Cui Zhu killed the king. Cui Zhu killed him again. Then it was Taishi's grandson's turn to write, and the young child who was less than six years old still wrote four words with his immature hand: Cui Zhu killed the king.

Such a persistent spirit made Cui Shu helpless, and he had to give up the plan to let Taishi change history and let them record the real history.

And the hereditary profession of Taishi is not only so persistent in recording the true history, but also has the same spirit in the pursuit of truth! Zou Yan also came from this background, although he was a little dissatisfied with Dai Yan replacing him as the youngest bachelor. But in the face of true truth, all of this is secondary!

And these people who followed Zou Yan were not different from Dai Yan's youth, and when they saw Dai Yan, they all saluted Dai Yan as a disciple.

As soon as one of the older scholars saw Dai Yan, he immediately fell into a frenzy and asked Dai Yan: "Yanzi, Zou Zi and I have told you about your heliocentric theory and the theory that the earth is a sphere, and I can't sleep at night!" After thinking about it repeatedly, I felt more and more that this doctrine was broad and profound, and that it was closer to the truth than our research. However, there is one thing that I am more and more puzzled about: according to you, the earth is spherical, so why did we not fall? How did the change of day and night and the change of the seasons of the year come about? You must tell me about it. ”

Dai Yan was naturally unable to ask for a student to come to the door on the first day. So he invited Zou Yan and these scholars to come into the lecture and draw a rough model of the entire solar system on the blackboard, so that everyone had a more intuitive feeling of the heliocentric theory proposed by Dai Yan.

Dai Yan pointed to the model diagram and said: "This is actually the general environment in which we live today, and Zou Zi called my doctrine heliocentric theory, which is actually inaccurate. In the universe, the sun is just like the stars in the sky. Such stars have planets like Earth and Wuzheng orbiting around them, and they seem to be motionless, so I call them stars. And the larger environment we live in is actually in this Milky Way in the sky, which I call the Milky Way.

As for the transition of day and night, it is actually related to the rotation of the earth. The change of the four seasons of the year is related to the rotation of the earth. As for the fact that we stayed on the earth and did not fall, and the stones thrown into the air will eventually fall to the ground, it is all related to the gravitational pull of the earth. If you're really interested, I'm afraid I won't be able to explain it in a moment. You also have to learn the basics of logic, and many more basics to understand. ”

What Dai Yan said, for these people who sincerely seek the truth, naturally they will not care. So they said to Dai Yan neatly: "As long as Yanzi is willing to teach, we will definitely study hard!" ”

Then Dai Yan asked Tangzi to give lectures to these scholars instead of him, and Dai Yan began to communicate with Zou Yan in private.

In fact, the basic knowledge mentioned by Dai Yan includes not only logic, but also linguistics. When Dai Yan created this whole scientific system in Fengyi, it actually made the Mohists spend a lot of time creating professional texts and professional academic terms. Moreover, he directly introduced the symbols and punctuation of later generations, and invented the method of using formulas to express truth.

All this made Zou Yan and these disciples feel extremely new. When they first came into contact with this doctrine, they did feel unusually troublesome. However, after a long time, it was found that these measures brought by Dai Yan were extremely effective.

With symbols, what cannot be clearly expressed in language can also be clearly expressed. With punctuation to break sentences, those ambiguous words can immediately become clear and abnormal. These people immediately thought that these measures invented by Dai Yan could be introduced into their respective work, such as recording history, and clear sentences can make the historical truth clearer. For example, when drafting documents for the monarch and recording data, you can use those simple numeric symbols.

These measures soon began to spread around the world as they were used. In the future, when everyone mentions punctuation, numbers, and symbols, everyone will naturally associate Dai Yan.

What surprised these disciples even more was geometry and physics. As soon as everyone comes into contact with the knowledge of geometry, they don't know how happy they are in the face of this deduced absolute truth!

They have pursued truth as an ideal all their lives, and they have finally begun to touch the edge of truth!
