Heaven and earth are yellow, the universe is desolate, the sun and the moon are shining, and the sun and moon are shining. Pen, fun, and www.biquge.info

The sixteen characters at the beginning of "A Thousand Words" are the universe introduced. Space; The universe, time, and the universe are the sum of time and space.

Li Chunfeng felt as if he was standing in front of a hidden door, and as long as he stretched out his hand, he could push open the door to a new world. But he stood still all the time, and the images of the sun, moon and stars kept flashing in his mind, as if they were telling him something.

"Are you alright?" Wang Mai looked at Li Chunfeng strangely, this young man had been standing in front of the armillary sphere for a full quarter of an hour, the whole person seemed to be out of his body, no matter how he called it, there was no response, could it be that he had fallen into an evil spirit?

"Assistant Teacher Wang......" Li Chunfeng finally came to his senses, "I had a very bold guess just now, it's just ......"

"Just what?" Wang Mai looked at Li Chunfeng, how did this young man speak so much, as if he was a different person, and he didn't think about the genius boy with quick thoughts just now.

"It's just that if I say it, I'm afraid that Assistant Teacher Wang will laugh at me for being a fool." The expression on Li Chunfeng's face was very entangled.

"But it doesn't hurt to say it." Wang Mai smiled and patted him on the shoulder, I haven't seen anything, I've experienced all the crossings, and I'm afraid that you, a seventeen or eighteen-year-old boy, have some shocking guesses.

"Then I'll be blunt," Li Chunfeng turned his head to look at the armillary sphere, "I think there's something wrong with this armillary sphere." ”

"Do you think there's something wrong with the armillary sphere or does the armillary say there's a problem?" Wang Mai finally understood what he wanted to say, but this young man's thinking was too avant-garde.

"Since I was a child, I have followed my father to observe the stars and deduce the calendar, but there is always one thing that I can't figure out anyway." Li Chunfeng touched the copper ball of the armillary sphere and said.

"I want to hear about it."

"According to the theory of the heavens, the sun, moon and stars all revolve around the earth, but I found that some stars are not like this." Li Chunfeng frowned, "Their rotation trajectory is very strange. ”

"What's this strange method?"

"Assistant Teacher Wang, please see," Li Chunfeng walked to the table and stopped his pen by drawing a semicircle on a piece of paper, "halfway through the operation, it turned abruptly, and after a small circle, it returned to its original position. "The round shape on the paper has a few extra ears, which looks weird.

"Very strange indeed," Wang Mai nodded, "and how do you think this situation should be explained?" ”

"If the stars do not revolve around the earth, but around the sun, then such strange orbits can be fully explained." Li Chunfeng pointed to the astronomical telescope, "Just like this star, if there are really stars revolving around it, then we will look on the earth with a pattern similar to that on this piece of paper." ”

"That's right!" Wang Mai looked at him incredulously, such a young boy unexpectedly discovered heliocentrism, he remembered, the discovery of heliocentrism in the West was nearly a thousand years later. What's going on? Whether it was the original history that he discovered but later generations did not know, or because of his own arrival, which triggered his inspiration, Wang Mai was in turmoil at the moment.

"That is to say, Hun Tian said yes...... Wrong? Li Chunfeng said his conclusion in disbelief.

"Not necessarily." Wang Mai didn't dare to look directly at the look in his eyes, thinking of the great men in the West who paid a heavy price for heliocentrism. Li Chunfeng in front of him is just a child who has not yet reached adulthood, and he can't imagine how he should bear such consequences.

"Why did Assistant Teacher Wang say this?" Li Chunfeng looked at him strangely, he agreed with his point of view just now, why is he flickering now?

"It's just a guess on your part, and there's no convincing evidence." Wang Mai sighed.

"Does Assistant Professor Wang agree with my reasoning just now?" Li Chunfeng asked.

"I agree, but ......"

"Since Assistant Teacher Wang agrees, that means that you also have doubts about Hun Tian's theory?" Li Chunfeng clung to his weapon like a warrior on the battlefield.

"Yes." Wang Mai replied, "But ......"

"If you agree, why do you bother to talk about him?"

"I said it's just speculation, and you don't have evidence, so how can you talk nonsense." Wang Mai said with a little weakness.

"Hun Tian is just a guess, our guess is more reasonable than Hun Tian said, naturally it is not nonsense." Li Chunfeng said righteously.

Why is this kid so tough? Wang Mai had no choice but to say to him his scruples about the matter: "Think about it, if you raise this question at this time, then who will be happy and who will oppose it?" ”

"Who?"

"Daomen has been insisting on it for almost five hundred years, right? Now you go and tell Yuan Shoucheng and those old Taoist priests, the universe is not like this, you people are wrong, what will be the consequences? Wang Mai reminded him.

"What consequences?" Li Chunfeng asked puzzled.

Why is this person's IQ explosive, and his expression quotient worrying? There was no way Wang Mai could only give him a little hint in more detail: "Many people in your Dao Sect rely on the astrology of this Hun Tian to eat, if this Hun Tian is completely wrong, people will no longer believe in astrology, then can they still eat?" ”

"Can't ......" Li Chunfeng understood the truth in an instant just because of this, "But you can't ignore the truth just because of this, right?" ”

"The truth?" Wang Mai shook his head, "Speculation is speculation, and you have no evidence, how can you talk about the truth?" ”

"Please give me some advice." Li Chunfeng bowed to Wang Mai.

"I can't talk about pointing, so I'll give you a hint." Wang Mai pointed to the calculation paper that Li Chunfeng had just used on the table, "If you can use this method to calculate the trajectory of the stars, this is the most convincing evidence." ”

"Calculated?" Li Chunfeng looked at Wang Mai with his mouth open, "How is this possible?" ”

"Whether you believe it or not, anyway, that's all I say, you can think about it yourself." When Wang Mai said this, he closed his mouth and said no more. Even if you Li Chunfeng is a genius, if you want to complete the achievements of the three generations of Ptolemy, Galileo, and Newton by yourself, how can it take seventy or eighty years, I don't believe that you, a young man, have such perseverance and can face such a boring process independently for decades.

Wang Mai didn't expect his progress to be so rapid. After only one rest day, Li Chunfeng came to the arithmetic school with a thick pile of paper.

At this time, Wang Mai was teaching Wang Er and Liang San elementary functions, and Li Chunfeng saw the two of them crackling the abacus, and curiously took this new thing from Wang Mai's hand.

"This is called abacus, and now Luoyang has just become a popular calculation tool." Wang Mai explained to him the use of the abacus and gave him the formula.

Li Chunfeng quickly mastered the use of the abacus, much faster than Wei Zheng at the beginning, Rao is Wang Mai was a little mentally prepared, and he was also shocked by his talent.

"Look," Li Chunfeng put down his abacus and spread out a piece of paper in front of Wang Mai, "I have already drawn all the observation records of the Taishi Bureau for nearly five hundred years on paper, and finally got this pattern." ”

Wang Mai looked at the exquisite map of the planets of the solar system in front of him, and couldn't believe that this map was completed by this young man in only five or six days: "You got it yourself?" "If that's the case, this Li Chunfeng is not only a genius, but also a Wenqu star.

Fortunately, Li Chunfeng shook his head: "Most of them were helped by the Taishi Eunuch, and I only did the final finishing work." ”

Wang Mai finally breathed a sigh of relief: "Then what do you want to ask?" ”

"These tracks are still not right," Li Chunfeng pointed to the exquisite circle on the picture, "The real trajectory is not like this, but I can't figure out the reasoning, so I ask Mr. Wang to give advice." ”

"I guess you've already drawn the real trajectory, right?" Wang Mai asked.

"Here." Li Chunfeng took out a sheet from a pile of paper and spread it in front of Wang Mai.

Wang Mai touched the rough paper, the elliptical orbit on it was so familiar, closed his eyes and let out a long breath before he slowly spoke: "You must be very strange why this orbit is not why it is not a standard circle, but the current strange situation." ”

Li Chunfeng nodded: "Please sir." ”

Wang Mai beckoned to Wang Eryue and Liang San.

"Sir." The two came to Wang Mai and saluted.

"You go and invite the gentlemen of the country to the debate." Wang Mai commanded.

"Yes." The two of them bowed at the same time and walked out of the arithmetic school.

"I'll do an experiment with two of my students in a moment, and the content of the experiment is related to your doubts, so please follow me to the debate field."

"Experiments?"

The arena is reminiscent of the Roman arena, except that it is an open-air underground building. Overlooking on the ground, the whole debate field is fan-shaped, the narrow end of the fan is the lowest part, the depth reaches six zhang, this is also the location of the podium, the length of the podium is three zhang, and the width is about one zhang. The walls are curved sound walls made of stone, which ring around the entire length of the venue, ensuring that the people on the podium can speak and the audience at the top and furthest of the auditorium on the opposite side can also hear.

The whole venue was designed after consultation between Wang Mai and the officials of the Ministry of Industry, and it can accommodate up to 7,000 people at the same time, claiming to accommodate 10,000 people. The site was built on a dirt mountain bag next to the imperial city, because the construction period was urgent, more than 1,000 migrant workers were mobilized at most, and it took more than a month, and now it has reached the final stage.

There are two tunnels about ten zhang long dug on both sides of the podium for drainage and passage. The four walls of the tunnel are supported by wooden planks, and there are pillars supporting the top wall at regular intervals to ensure that the tunnel does not collapse. The problem of the whole project is also that the excavation work of these two tunnels, because the working surface is too narrow, and the wall support has to be done while excavating, so it has to start day and night, until yesterday, it was initially completed. The two tunnels can accommodate four people side by side, and are used as access roads for VIPs and can also be used as emergency evacuation routes, with sewers under the planks under their feet to prevent water accumulation during the rainy season.

Wang Mai and Li Chunfeng were walking in the tunnel at this time, Li Chunfeng looked at this deep corridor curiously, the dim oil light stretched the shadows of the two for a long time, because it had just rained last night, there was a thin sound of running water under his feet.
