The next day, Chao Yong came to the palace with a telescope.
It took ten days to finish the book on mathematics. Firstly, the content written by Chao Yong was only some introductory knowledge. Secondly, ancient arithmetic was also very developed. What Chao Yong taught did not have much new content. The students are all talented people, so the teaching process is very fast.
Chao Yong also selected several outstanding people and asked them and Qin Hui to continue teaching mathematics in Taixue.
Chao Gai has decreed that in the future, mathematics will be added to the examination of Imperial College, and the imperial examination will have to wait until mathematics is popularized throughout the world.
??????????????????????????????????????????????????????????????????????????????????????????????????????? The promotion to a higher school depends on the ordinary grades, and those who are in a higher rank can be directly promoted to officials, so the students of Taixue are still very enthusiastic about learning mathematics.
When Chao Yong arrived at the palace, the morning court had already dispersed, which Chao Yong deliberately avoided. Most of the matters dealt with in the morning court were political affairs in various places. Although they could not be said to be trivial matters, Chao Yong had no interest in those matters, so he usually did not go to the morning court.
He hates others grabbing power, but he is definitely not greedy for power. If he were made emperor, all these matters would be left to the ministers, and he would only be involved in military and state affairs. In peacetime, he would be a carefree emperor.
Chao Gai also delegated a lot of power, but there were still a lot of memorials handed to him. After the morning court, he kept looking at the memorials.
"See my father."
When Chao Gai heard Chao Yong's greeting, he put down the memorial in his hand. Seeing Chao Yong holding a box in his hand, Chao Gai smiled and said, "What did you make again? Your mother liked the silver mirror that she sent yesterday. , I¡¯ll give a few more to your mother later.¡±
Chao Yong smiled and said: "Since the Queen likes it, I will have a few more made and delivered. Here are magnifying glasses and telescopes. The magnifying glass can make things look bigger, and the telescope can make people see things in the distance clearly."
With that said, he walked to Chao Gai, took out a gold-handled magnifying glass, and placed it on the memorial. The small characters on the memorial immediately became much larger.
Chao Gai nodded and said, "This magnifying glass can help people with poor eyesight read."
Chao Yong smiled and said: "There are special glasses, but my father's eyesight is very good, so I didn't bring them. The magnifying glass is not of much use, this telescope is a good thing."
As he spoke, he picked up the monocular and said, "Father, just look out from here."
Chao Gai took the telescope and put it to his eyes.
The pillar in the distance suddenly appeared in front of him, as if he was bumping into it. Chao Gai subconsciously dodged back.
Seeing that the pillar was still there, I realized that it was the telescope that was causing trouble. I curiously raised my eyes to look at it again. The pillar in the distance seemed to be many times larger, and it was right in front of me, so I could see it very clearly.
I couldn¡¯t help but wonder: ¡°How far can you see?¡±
Chao Yong said with a smile: "It's hard to say, it depends on how clear my father is. Let's go outside and try it, and then our father will know."
"good."
Chao Gai looked at the Chui Gong Hall for a while, then put down the telescope and praised: "Good thing, this should also be used in military affairs."
Chao Yong nodded and said: "With a telescope, it will be easier to detect, and it will be difficult to ambush our army. With the telescope and the spacecraft, there should be no problem in seeing for more than ten miles."
"It's a good thing. It's really a magic weapon. It must not fall into the hands of the enemy."
Chao Yong said hurriedly: "Actually, this thing is easy to make. As long as you learn the physics I wrote, you can know how to make this telescope. I can't hide it from others. I want to open a mirror shop to sell glasses, magnifying glasses, and telescopes for the court." Add a source of wealth.¡±
Chao Gai handed the telescope to the eunuch waiting next to him and said, "Put it away."
The eunuch also saw that Chao Gai had something to say to the prince, and hurriedly stepped away with his telescope.
Chao Gai frowned and said: "Physics is so powerful that it can make spaceships and telescopes. How can you teach physics to people? Nowadays it is said that physics is theology. There were spaceships before, and now there are telescopes. If not theology, what is it? . Such powerful skills can only be passed on to sons, not to daughters, let alone to outsiders."
Chao Yong also knows that physics is still a bit of a secret for this era, although many sages have discovered some physical knowledge. For example, Mozi mastered some knowledge of optics and discovered the principles of convex lenses, concave lenses, and pinhole imaging. , but it was not elaborated in detail in the book, but simply recorded. Using beads to make fire and using ice to make fire are also recorded in "Guanzi" and "Huainan Wanbi Shu".
These sages may have thought that these things were very simple and that as long as they left a few words, future generations would know about them. However, without detailed descriptions, a lot of knowledge was lost. It may take hundreds or even thousands of years for someone to figure it out again.Some knowledge.
Of course, the application of telescopes to optics exceeds the use of ice to make fire. At least no one has made a telescope before.
However, Chao Yong did not want to hide these "unique knowledge". Once he hid it, it is very likely that future generations will keep it. When other nations start to move towards science, they will really become a treasure for themselves. The physics he wrote is not something profound, it can only be described as introductory stuff at best. Once a nation starts to study it, these things will be all over the street. And China is likely to still follow the same old path. Poems, books and etiquette have been passed down from family to family for thousands of years, and then guns and cannons, or science, knocked on the door.
Chao Yong is confident of sweeping the world, but this does not guarantee that the Han people will always be on top of the world. There is no empire on which the sun never sets. Once Europe breaks through the darkness of religion and accepts the baptism of science, history may repeat itself. Therefore, Chao Yong wants science to sprout in China and be the first to accept the baptism of science. In this way, even if we cannot dominate the world in the future, we will not be beaten for falling behind.
What he wants to do is to promote mathematics and physics with his overwhelming force, so that people can learn to understand the world objectively, instead of blaming God for things they don't understand.
Of course, we do not lack ancestors who objectively understand the world, but just as the European sages were persecuted by religion, our ancestors who truly understand the world are often killed by various forces. In order to protect the emperor's empire and maintain the interests of certain people, Even in order to maintain etiquette, a lot of knowledge has been lost in the long river of history.
However, Chao Yong could not tell Chao Gai these things directly. He could only say: "It is actually difficult for us to keep secrets. As long as the spacecraft is used too much, everyone will find that the spacecraft only has a pile of fire. In addition to the example of the Kongming Lantern, people are very It's easy to imitate a spaceship. It's just that they don't know the principle of a spaceship, but it doesn't affect them. Besides, what if this telescope is given to the enemy? The horses can easily gather together, so there is no need to play tricks with them. We can defeat them with a majestic formation. In fact, the most powerful weapons we have are gunpowder and the guns we are developing. As long as we have them, we can defeat all enemies. "
Chao Gai thought for a while and said, "What's the benefit of teaching physics to the world?"
"It can allow people all over the world to understand the world more objectively, guide people all over the world to explore all things in the world, enrich this knowledge, and then create more powerful things."
Chao Gai couldn't help but asked curiously: "What other powerful things can be created?"
Chao Yong smiled and said: "A spaceship that can fly to the moon, a submarine that can dive to the bottom of the water, and a car that is faster than a Maxima."
Chao Gai was stunned and said: "Can you fly to the moon?"
"Yes, but such a spaceship requires very advanced science, and I'm afraid it won't be possible to build it for hundreds of years."
Chao Gai heard that it would take hundreds of years to build it, so he couldn't help but said in disappointment: "Then we won't be able to see the moon."
Chao Yong naturally knew that what Chao Gai meant was seeing clearly, not the small moon hanging in the sky every night. He thought about it and said: "In the future, we can let someone try out an astronomical telescope, and then we can see the moon clearly." It looks like this. In fact, there are no moon palaces and laurel trees at all, let alone Chang¡¯e and Wu Gang. It¡¯s just a bumpy planet.¡±
Chao Gai said in disbelief: "There is nothing on the moon?"
Chao Yong nodded and said: "Nothing."
Chao Gai would not doubt Chao Yong's words, but this fact still made it difficult for him to accept.
After a while, he said: "So, the legend of the moon is all false."
Chao Yong said helplessly: "Maybe those stories are just stories told to children, and everyone takes them seriously as they are passed around."
Chao Gai couldn¡¯t agree with Chao Yong¡¯s words, but he couldn¡¯t find a better explanation and said, ¡°I¡¯ll ask someone to make an astronomical telescope later and send it to me.¡±
Chao Yong nodded and said: "The first astronomical telescope must be sent to the palace. I would like to ask my father to remove the ban on astronomy. In fact, the eclipse of the moon by the dog and the broom star are all special astronomical phenomena. It doesn¡¯t predict anything at all. Although the theory of telepathy is not completely nonsense, it is basically unbelievable. If anyone uses astrology to interfere in politics, it will be regarded as nonsense.¡±
Chao Gai was stunned, and suddenly said: "What about the stars you mentioned descending to earth?"
Chao Yong also hesitated for a moment, and immediately said: "The stars I am talking about cannot be seen by humans, just like there are gods in the sky, but they will never be known to others, let alone worshiped by humans. In their view, Human beings are just ants, so what¡¯s the use of them enjoying our incense, just like we don¡¯t want ants to worship us.¡±
Fortunately, when Chao Yong wanted to destroy the religion, he thought of an explanation for himself, otherwise he would have beenAsked. If Chao Gai knew that Chao Yong had been lying to him, he would have to take care of him. He shuddered when he thought of the family treatment Chao Yong suffered when he was a boy.
Chao Gai thought for a while and said: "You are right, why do we need ants to worship us?"
Chao Yong continued to instill his atheism: "Father, think about it, people in the past have said that the Purple Star descended to earth, but when did the Purple Star disappear? It can be seen that there really is a star king, and it is not the stars in the sky. On the contrary, , What's the point of interfering with the government's affairs with those stars? Most of the effect of the theory of telepathy is to restrain the emperor. Changes in the sky, floods and droughts in the human world are all natural phenomena, and have nothing to do with the emperor's character.
"Just like this year, my father ascended the throne and exempted the world from agricultural taxes and corvees. It can be said to be a benevolent government. Floods, droughts, and locust plagues are all over the world. If the new dynasty hadn't just been established and the steel swords in our hands hadn't been returned to their sheaths, I'm afraid many people would have written a letter saying that our father had lost his moral character, or even asked him to issue an edict to punish himself. "
Chao Gai said with a smile: "It's true that someone wrote a letter saying that my killing in Daliang was too heavy, and asked me to grant amnesty to the world."
Chao Yong didn¡¯t expect that Daliang was still killing corrupt officials everywhere, so someone dared to jump out and couldn¡¯t help but ask: ¡°Didn¡¯t the father deal with him?¡±
Chao Gai shook his head and said: "Previously we made a law that we would not be punished for our words, so there are more upright people in the court. If we punish them for this, I am afraid they will become people who only know how to flatter."
Chao Gai shook his head and said: "Only when you killed Li Qianshun privately, Zhang Shuye took the lead in impeaching you, and a few people seconded it. Other than that, no one impeached you. You were the leader of the killing, and you rarely retreated when encountering trouble. I'm afraid they were all worried. You will take revenge afterward. Of course, this is also related to the fact that there are few truly upright people in Zhao Ji's court. Many ministers who were not afraid of the powerful were demoted to various places by Zhao Ji. After Zhao Zisong went to Jiangnan, he helped Zhao Zicheng recruit a group of people who had been compiled by Zhao Ji. The officials who control and criticize are the real upright people, and the people in the government are just people who adapt to the situation. "
Chao Yong smiled and said: "There are only a few people who are not afraid of the powerful. Whether most people are upright or follow the crowd is actually decided by the emperor. What kind of people the emperor likes is what they are. People who dare to go against the times will always They are a minority. There are also many people who have become upright in the Zhao Ji Dynasty."
Chao Gai nodded and said: "You are right. I have read many people's previous memorials. Many people used to either follow the trend or rarely discuss politics, but now the memorials are quite insightful. He dared to argue with Wu Yong and others on different political matters, and he was almost like two different people from before. "
"For us, these people are much easier to use than Li Gang and others. When we overthrow the Song Dynasty, Li Gang and others will not be used by us, but these people can be used by me. Their talents may be higher than Li Gang. It¡¯s just that his character is not as good as Li Gang.¡±
Chao Gai nodded and said: "These people are villains after all. They may cause harm to the world again. They cannot be used in a big way."
Chao Yong shook his head and said: "I don't think so. Whether they can be gentlemen for a lifetime depends entirely on the emperor. As long as the emperor's preferences remain unchanged, for the sake of their official positions, they will not change. Just like Cai Jing, Zhao Ji just became emperor. At that time, Cai Jing was also a capable minister. If Zhao Ji could continue to work hard, it is not certain that Cai Jing would be able to live forever. But later, Zhao Ji was greedy for pleasure, and Cai Jing only wanted to plunder the people for Zhao Ji's enjoyment for the sake of his position. "
Chao Gai thought for a while and said with a smile: "What you said is not unreasonable. As long as they have merit, I have to give them promotions. There are rewards and punishments for merit. As long as they don't do anything wrong, I can only watch them. I have risen to a high position step by step, but I am afraid that I will be ridiculed by others in the future, as I will only use the villains who follow the trend of the Song Dynasty. "
Chao Yong smiled and said: "No one would think that my father was incapable of employing people. In the Tang Dynasty, Wei Zheng was first in the Wagang Army, and later became Li Jiancheng's staff. Li Shimin killed Li Jiancheng, and he became Li Shimin's official again. He and Li Jiancheng There is no difference between Lu Bu, but Lu Bu failed to achieve anything in the end, while Wei Zheng made great contributions to the rule of Zhenguan, so he became an admonisher through the ages, and Li Shimin also gained a reputation for knowing people and making good use of them.
The more you rely on people like Zhao Ji to govern the world, the reputation of your father will be improved. Of course, Zhao Ji's reputation will probably get worse.
Those who do evil in the Zhao dynasty have been guilty. Although the rest are mostly inflamed, they are just Mingzhe's body or greed for wealth, and they have not done anything evil. There is nothing wrong with Emperor Father appointing them. There are a few people in the world who are not greedy for wealth. If those scholars were not for the golden house and beauty, how many people would be willing to study hard every day and even hurt their eyes. Glasses are mainly sold to those scholars. "
Chao Gai is theHe was generous, but he also had a jealous temper, and he was always worried about the appointment of villains from the Song Dynasty. After chatting with Chao Yong for a while, the grudge in my heart was finally eliminated.
It was not easy for him to say these words to Wu Yong and others, especially after arriving in Tokyo, Wu Yong and Zhang Shuye kept asking Chao Gai for power, and Chao Gai and Wu Yong inevitably became estranged.
Hearing Chao Yong make fun of scholars, he couldn't help but laugh: "You seem to have a lot of opinions on scholars. I come from a martial arts background, and I like martial arts more than literature, but I don't have such a prejudice as you. We rely on the Liangshan brothers to conquer the world, but governance The world still depends on these scholars.¡±
Chao Yong shook his head and said: "I don't have a problem with scholars, but with those who study to death and think that everything is inferior. Only the scholars who are well-educated have a problem with them. They didn't see the invention of gunpowder, spaceships, and telescopes when they were studying. They know how to recite poems and lyrics every day and study the complicated etiquette. In recent times, they can neither resist nor educate the Liao people with books. What is even more shameful is that they have no guts to buy from the people's hard-earned money. In order to achieve peace, the people's hard-earned money is squandered internally. The people can't afford three meals a day, but the sergeants and officials in the court are not tired of fine food and fine food. Of course, I am not completely opposed to scholars, otherwise I would not go to Taixue to give lectures. ¡±
Chao Gai felt relieved when he heard what Chao Yong said.
Chao Yong thought of what he had said before and asked, "Which loyal ministers and good generals did the Southern Song Dynasty invite?"
Chao Gai said: "The most famous people are Jiang You and Zongze. Both of them are upright. Jiang You once reached the third rank of Zhengzheng, and served as the Minister of War, the Ministry of Industry, and the Minister of Personnel. Although Zongze's official position was not high, However, he was widely respected. During the palace examination, he wrote more than ten thousand words to criticize the evils of the times. After becoming an official, he was not afraid of the powerful and loved the people like a son. Later, he was dismissed from office because he opposed the alliance with Jin Dynasty to destroy Liao Dynasty. He was also accused of despising Taoism and was made redundant. Guan Runzhou. After Zhao Zisong went to Jiangnan, he hired two people from Runzhou to serve as officials, and then successively appointed some popular officials. During this period, the Southern Song Dynasty also gained some popularity. "
Chao Yong was naturally familiar with the name Zongze and said with a smile: "They invited these people just to make wedding clothes for us. Without good soldiers and generals, even if loyal ministers from all ages gathered in the Southern Song Dynasty, how could they resist my army. "To be continued. )
