This is a special conference room, Mao Geng presided over a meeting of more than a dozen people in this conference room, today, this has become a multi-purpose hall.

Last night, Lao Qiu took the trouble to prepare for a long time in this conference room, and there was nothing else, just writing the blackboard. If you want to talk about astronomy, if you want to say that the psychological pressure of lecturing to Zhu Xi is really big enough, Lao Qiu felt in his heart that this seemed to be a special report for later generations, and the leaders of later generations would inspect it, and sometimes they would pretend to let you put a carefully prepared projection. With the help of Tan Wangdi, Lao Qiu was very diligent, drawing and writing on the blackboard, busy for a long time, and then ran to the back to look at it for a while, turned around and revised a few places, and then nodded.

Tan Wangdi also thinks that the chalk words of this "returnee" Mr. Qiu are dancing like dragons and phoenixes, compared to his master Mao Genglai, the style is very different, Mr. Mao's chalk words are regular, about the same size, but Mr. Qiu's chalk words have a strong calligraphy flavor. Compared with Mr. Qiu's board book, Mr. Mao's chalk writing is a little more rigid.

I can't help but say that Lao Qiu's painting and calligraphy skills are okay, Lao Qiu said in his heart, and I don't know how Zhu Xi's old master practiced chalk writing at this time, it is estimated that Zhu Zi's teaching also used the blackboard that has just become popular, but it is expected that Zhu Xi's chalk words must be inferior to brush words, chalk and brushes are much worse after all. No one has specialized in chalk writing these years, and Lao Qiu doesn't think that his chalk writing will disgrace the crossing world.

Today is the 15th, which is the rest day of the Special Administrative Region, and it is inconvenient to arrange for Zhu Xi and his party to visit around, so this lecture was arranged.

In the conference room at this moment, in addition to Lao Qiu Zhuxi and his party, 6 Jiuyuan was also present. Tan Wangdi served tea one by one very quickly, but the students ignored it, and all of them only stared at the content on the blackboard.

Lao Qiu was both excited and apprehensive, excited that he was very accomplished in revealing the secrets of the universe in this era. I was nervous about not knowing what the consequences would be. Joke! Sitting in the audience are influential figures, contemporary masters who hold the power of public opinion, and you are ashamed to spread subversive astronomical theories, but this theory is difficult to prove. Who knows if it will be regarded as a demon! So, it's impossible not to be nervous.

In fact, 6 Jiuyuan was exposed to some astronomical theories of later generations, but it was very unsystematic, Mao Geng didn't know what to worry about before, anyway, he just showed a scale and a half claw with 6 Jiuyuan, according to Mao Geng himself, if you want to talk about astronomy, you have to talk about gravity, and I am afraid that gravity will not be understood.

Zhu Xi has been studying astronomy for the past few years, so Lao Qiu thinks that he should give the old man a science popularization to save him from taking many detours.

Lao Qiu pretended to be calm and walked to the front desk, but his heart was pounding. It is said that the Great Song Dynasty is relatively open, and it must not be like the European Church in the Middle Ages, thinking that Bruno's child was really unlucky, just because of the propaganda heliocentrism, he was burned at the stake by the church, which is really sad.

What a mess, what do we want to do with this unlucky thing!

Lao Qiu cleared his throat and began to speak:

"Today, at the request of Mr. Yan, I would like to introduce the research of the Hatang Kingdom on astronomy. If there is anything wrong, please correct Mr. Zhu and Mr. 6! ”

Once he started, Lao Qiu was not so nervous. What I want to talk about is the basic common sense of future generations, and primary school students know that we will popularize science for the elites of the Great Song Dynasty today.

－－－－－－

Lao Qiu was holding a class in the conference room over there, but Mao Geng was bored in the office here, so he picked up a sketch and began to revise it on it, and his mind calmed down.

was painting, at this time Tan Wangdi knocked on the door and came in, Mao Geng hurriedly asked:

"How? How effective was Mr. Yau's lectures? ”

"I'm listening quietly, Mr. Qiu said it well, the moon revolves around the earth, and the earth revolves around the sun,---, I see that Lord Zhu is listening carefully, as if he is afraid of missing something." Tan Wangdi came out halfway to report the reaction to the lesson, which Mao Geng had explained in advance.

"Oh, that's right."

That's good, it looks like a group of people with high IQ, and it's quite quick to accept new things.

It is said that Zhu Xi also deduced that the light of the moon comes from the sun, and the moon itself is not light, and speculated that some stars are the same as the moon, and the light comes from the sun, and also speculated that some stars can be light themselves, which is really commendable.

As soon as Mao Geng saw that the shape was good, he involuntarily walked outside the door of the conference room, hesitating in his heart whether to walk into the class halfway at this time.

Just as I was hesitating, the inside suddenly became lively.

The first question is:

"Why does Mr. Yau think that the earth is a ball? When we look at the earth, it is clear that it is flat. ”

"It's simple, because the ball is so big. If you want to prove that the earth we are on is a ball, you can return to the place where you came if you don't believe it. ”

In order to prove his point, Lao Qiu continued:

"In two days, I will ask you to take a look at the globe and see how the six places and oceans on the earth are distributed."

Mao Gengxin said Lao Qiu, you are good, the grandfather of the country Zhao Lian locked the globe as a baby, don't you want to devalue the treasure of the grandfather of the country! But it's going to be public anyway, and it doesn't matter if you eat a little early.

Another voice asked:

"According to Mr. Qiu, whether it is the sun, the earth, Venus, Jupiter, they are all hanging in the sky, and what gravity is there, you revolve around me, I revolve around you, anyway, all of them turn well, and none of them will fall down, so mysterious, how does Mr. Qiu know? How can it be proven? ”

Lao Qiu Khan, I can't tell you this in my heart. I'm a liberal arts student, and I don't know why.

"Mr. Qiu said that the sun has been burning, and said that it can burn for hundreds of millions of years, which is really incredible, how can it burn for so long! If the sun burns out, won't there be no light! The world will be dark! ”

Mao Geng said in his heart, not only is it dark, but life on earth will also be destroyed.

If you think about it, you really can't talk about astronomy casually, and when it comes to this, you have to talk about nuclear fusion, and when you talk about nuclear fusion, where can you explain it clearly for a while and a half.

"Mr. Qiu said that there is gravity, is there also gravity between two grains of dust, how can Mr. Qiu prove it!"

－－－－－－

One question after another followed, and Lao Qiu was asked a big head. I'm a liberal arts student, and I don't know why I know it, so it's good to be able to tell the Tao in front of me.

Originally, Lao Qiu's talent was good, but this is science, and Lao Qiu is facing university scholars of this era, and Lao Qiu doesn't dare to wave it indiscriminately.

At this time, 6 Jiuyuan came forward to solve the siege:

"Maudt once told me about astronomy and geography, although it is only a few words, but the earth is a sphere should not be wrong, Maute said, you can't see the mast of another ship at a distance on the sea, and you can see it when you are close, which proves that even the sea surface has curvature, well, it is a ball. I've asked many crew members about this experience, and many of them are new to hearing about it today, and I have some questions, but I think there is a reason for it. What does Brother Yuan Hao think? ”

Zhu Xi didn't say anything, didn't ask questions, kept thinking, and then said:

"What Mr. Qiu said is very mysterious, but it is too profound, and the old man is difficult to understand for a while, especially the theory of gravity. Of course, there are many wonders in the world, and there are miraculous creations in the heavens, and there is truth in them, and the old man does not dare to believe it, but Mr. Qiu's argument seems to be self-justifying, maybe it is true, and it needs to be proven. ”

Lao Qiu said in his heart, after all, these people who are engaged in learning are not primary school students in later generations, what do you say, for a blank piece of paper, the teacher only reads the book according to the book, and the students are convinced. I played the brand of Ha Tang Kingdom, but the brand of Ha Tang Guo was not working from time to time, and it still lacked authority.

In the afternoon, Lao Peng went to Zhu Xi's residence to acupuncture for the old gentleman, and naturally it was about astronomy and geography.

Lao Peng studied engineering, and he knew more than Lao Qiu, but his eloquence was not as good as Lao Qiu, and after talking for a long time, Zhu Xi still couldn't fully believe it.

Lao Peng said in his heart, I didn't expect that Zhu Xi, the old master, still has a considerable empirical spirit, and they all say that Zhu Xi is idealistic, but he seems to be quite materialistic in science.

"Learning from things", it seems that Zhu Xi's attitude towards things can be called rigorous.

In the evening, accompanied by Huang Gan, Zhu Xi went to find 6 Jiuyuan to observe the vast sky together, trying to verify the truth, but the weather at night was not cooperative at all, and it was estimated that there would be no gain, and there would be no breakthrough in one night.

At the same time, Mao Geng, Lao Qiu and Lao Peng were chatting in the office.

"Lao Qiu, if you want it, you can't reach it, we haven't established absolute authority yet, my idea is actually very simple, don't force people in this era to accept you and your theory, or focus on guidance. Just like fishing, I like fishing in my last life, as long as I prepare the bait, the fish will always be fishing, I must be patient, I sometimes sit for a long time and can't catch a fish, maybe the next moment I can catch a big one. Hehe, that's a little bit of my experience. ”

Lao Peng nodded and said approvingly:

"Maudt is right, I agree, we can't be in a hurry, I'm afraid we can't expect to instill the theories we have mastered into the people of this era overnight, we must first arouse their interest, we don't have to talk to them about any theories first, they themselves have knowledge, in the words of later generations, that is, the world view has been formed, we don't ask them to change their minds quickly, it is better to speak with facts."

Lao Qiu is an extremely smart person, and he immediately said:

"It's still Maud who thinks it through, you see, I almost made the mistake of being presumptuous."

Lao Qiu gave a sycophant to him, and Mao Geng just smiled.

Lao Peng Dao:

"When we talked in the afternoon, Zhu Xi was very interested in sweet potatoes, it seemed that the sweet potatoes were being harvested, so it was better for him to go and see the sweet potatoes harvested on the spot."

Lao Qiu smiled:

It is said that when Zhu Xi was an official, he paid great attention to the promotion of agricultural science and technology, and he was a representative of advocating scientific farming in this era. However, the biggest bait is not sweet potatoes, it should be the artillery musket that Mao Te has come out, Mao Te has come forward and has already discussed it with Guogong and Mr. 6, let Zhu Xi see the power of these firearms, and it is estimated that he will be able to speak for us. ”

Mao Geng nodded and said with a smile:

"Mr. Zhu Xi is so old, and he still has an angry mentality, such as moving the capital to Nanjing, which sounds a bit outrageous, but Mr. Zhu is really so popular, no one would have thought that Zhu Xi was so radical, if it weren't for Mr. 6's mouth, I really can't believe it!"

"Bloody! , such a temperament, I admire! On the other hand, as long as it is conducive to the Northern Expedition, Zhu Xi will definitely support it, and it seems that Zhu Xi's cooperation with us will not be affected by today's lecture. Hehe. ”
