After Guo Jiale finished speaking, everyone turned their attention to Yu Qian, the most promising and youngest genius in the Imperial College.
Yu Qian was a little nervous. What he faced this time was not his classmates in the school, but the Imperial College, no, almost all the geniuses in the cutting-edge knowledge of the Ming Dynasty. Everyone was more famous, qualified, and powerful than himself.
Ye Ling'er saw Yu Qian's nervousness and said with a smile: "The emperor said that young people are the most energetic and energetic, so just say it."
Yu Qian glanced at Ye Ling'er gratefully, bowed to everyone, and then said seriously: "I, Yu Qian, didn't dare to stand up and speak, but Brother Guo Jiale forced me to invite him, so he had to come. Since he is knowledgeable about the theory of the round earth, Qian Lue Say a few words, and please bear with me if there is anything inappropriate."
Hu Bi, Zhou Chang, Luo Feng and others laughed.
Compared to Guo Jiale, Yu Qian is a very humble person who can always be polite before fighting. Hu Hui admired Yu Qian very much, and because he had a close relationship with the prince, he thought highly of him even more. Obviously, although Yu Qian is young now, he already understands some official rules. These words are reasonable and comfortable.
Yu Qian said seriously: "My understanding of the theory of a round earth is mainly from navigation books such as logbooks and "Yingya Shenglan". I think that the theory of a round earth has been proven to exist in fact, and the sky is a round place. This statement can be abandoned from now on and no longer mentioned. A series of diaries and books have recorded problems with time and day and night changes, and even some date records have errors and omissions. From this point of view, the changes in day and night and the changes in the four seasons , probably all related to the round earth theory.”
"Day and night are formed by the rising and setting of the sun. What are the four seasons? On the earth and stars, some areas are like spring and autumn all year round, some areas are hot like summer all year round, some areas are as cold as winter, and some areas have four distinct seasons. How to explain this? ? I think that whether it is day and night or the four seasons, light and temperature are related to the sun. What exactly is this relationship? Is it related to the existence of earth and stars in the void? Yu Qian doesn’t know..."
With Guo Jiale and Yu Qian offering suggestions, the discussion began to heat up.
Yu Xinghai, the dean of the Institute of Navigation, stood up and highly agreed with Guo Jiale and Yu Qian's views. He ordered someone to bring a model of the earth and stars, and shouted to everyone: "This is a spherical map jointly created by the Institute of Navigation and Global Navigation. It was used to simulate the earth and stars. After the emperor saw it, he named it a globe and proposed to install a bracket for the globe, and that's how it came into being."
"Based on the experience of sailing again and again, there have even been situations where dusk and sunrise lasted for several hours. It can be seen that the earth or the sun is rotating, and only by rotating can such changes be possible. Analysis by the Institute of Navigation and the Qintian Supervisor, the tendency Since the earth revolves around the sun, this means that our earth is moving all the time. Please look at this globe..."...
Zhu Yunwen slowly walked into the Gewu Bamboo Forest and sat behind the crowd. He shook his head slightly at the person who found him and listened carefully to this meeting that had the significance of changing the times.
The theory of a round earth has been proven to exist, and its impact is by no means a matter of navigation, but an issue of the entire cultural system.
Since it is the theory of a round earth, the knowledge of the earth's rotation and revolution will naturally appear. Correspondingly, universal gravitation will gradually be discovered and confirmed, and the study of mechanics will also enter a new stage.
After more than ten years of changes in thinking, especially the influence of Reformed Confucianism and the Yongjia School, the thinking of the Imperial College students has become innovative and expansionary. They are no longer pedantic and stubborn believers, because the new knowledge books do not include No, they are more confident and firmly believe that they are the pioneers of new knowledge.
The emergence of the globe will change the perspective from which Ming people understand the world. However, this globe does not completely mark all islands and lands. Polar bears, penguins, kangaroos, etc. are not on the globe.
The world is very big, and it always requires generations of people to develop it. All missions cannot be compressed into one emperor in a few decades.
Zhu Yunwen listened carefully.
From the perspective of ballistic calculations, Tao Zengguang and Hu Yuancheng believed that there was some kind of force that pulled the gunpowder bomb down from the sky instead of flying all the time. In addition to the weight of the gunpowder bomb itself, there were other forces involved.
Regarding flying to the sky, Tao Zengguang shouted: "In the early years, the emperor told me that flying to the sky is feasible.
As long as it's fast enough. Over the years, the Second Artillery Bureau has conducted experiments again and again, and found that flying into the sky is indeed possible, but it is limited to the fact that the power of current firearms is insufficient to completely break through a certain speed..."
"Since the earth is round, we can definitely leave the atmosphere. Hot air balloons cannot do this because hot air balloons need air. If firearms can exceed the height of hot air balloons and fly to places where there is no air, it will be possible. Reach the sky, then look back at the earth..."
Hu Qiyi nodded repeatedly.
The higher you go, the thinner the air becomes.
If it goes any higher, the air will definitely disappear.
Where hot air balloons cannot go, can firearms go up? How much power and energy is needed to do this?
No one knows how far the Second Artillery Bureau's research has progressed, but one thing is clear. The people in the Second Artillery Bureau are more energetic and proud. Just look at the ruddy face of Tao Zengguang and Hu Yuancheng's pride. There must be new progress in firearms, at least some exciting breakthroughs.
Mao Zhoutai came on stage. This general who came out of the Navigation Institute became a unique figure after only two years of experience. Looking at Mao Zhoutai who spoke confidently, Zhu Yunwen nodded slightly.
It is a good thing for Ming Dynasty that talents come out from generation to generation.
When Guo Wenxing stood on the stage with a cane, he saw Zhu Yunwen in the crowd and immediately shouted: "Your Majesty."
When everyone heard this, they quickly looked at it, then stood up and saluted.
Zhu Yunwen stood up helplessly and raised his hand with a smile: "Everyone, get up. This is the feast of Imperial Academy knowledge. I am here uninvited. Don't be distracted. Just say whatever you want. You are standing at the door of the new knowledge. Besides, I believe that you will definitely be able to enter the hall of learning and achieve your glory, the glory of the Ming Dynasty!"
Hu Xi, Ye Ling'er and others laughed.
Zhu Yunwen had no intention of interfering with everyone's research. The Imperial College already had a clear direction, so there was no need to influence them. After leaving some encouraging words, he chose to listen and encourage these geniuses to express their opinions and understandings.
Song Duanduan stood up and started talking: "Since everyone believes that there is a mysterious power, we should give this power a name for future research."
Yu Xinghai, Luo Feng, Guo Jiale and others all agreed.
Given a name, even if no one knows why this power exists, it does exist and affects the world. There is always a name to study and explore.
Hu Hui stood up to support Song Duanduan: "It is right to give names. Without names, how can we examine things and write words. The Imperial College leads the learning and needs to give the new learning a name. As for this name, in my opinion, it is a good idea. Bring it to the Emperor."
Once this is said, no one will object.
After all, with the power of the sun, the moon, and the power of the universe, naming an emperor is most appropriate. Not to mention that Zhu Yunwen is here, even if he is not here, he should still send documents to ask for an order to name him.
Zhu Yunwen declined, but no one agreed, so he had to step up to the high platform and said with a smile: "Knowledge is just knowledge and has nothing to do with the court. Since you are wholeheartedly inviting me, I will give this power a name." There is always a mysterious force pulling all things together. The ancients said that pulling one hair can move the whole body. I hope you can pull this force to split all obstacles and ignite the technological flames of China! "...
"In this way, I call this mysterious force the force of traction, and name it gravity! Everything has gravity. With gravity, our earth and stars will float in the empty universe. With gravity, we can You will stand on the earth instead of falling into the void, there is gravity! Exploring and mastering the mystery of gravity is the direction of your future exploration, and it is also the beginning of Chinese civilization reaching a higher peak!"
