In the Song Dynasty, there was no law or order.

He loves his ancestors so much that he still can't forget the glory of his ancestors' donkey cart drifting.

Lu Yijian, Fan Zhongyan and others could hardly hold their nerve.

Zhao Zhen's face turned even darker.

No matter what, Zhao Guangyi is still his grandfather. Zhao Jun arranges for his grandfather every day, which is really too much.

Moreover, Zhao Jun is still a descendant of the Zhao family. Although he is not sure whether he is from the lineage of Taizu or Taizong, he is still a descendant of Xuanzu. How can he despise his ancestors?

Zhao Zhen clenched his fists, looking at the hateful sight of Zhao Jun lazily leaning on the recliner, blindfolded, and wanted to punch him hard, but after raising his hand high, he quickly let go.

Because after he looked around, he discovered that Zhao Jun was actually about 5.7 feet tall (180cm), and his body was very burly. It couldn't be said that he had a huge back and waist, but he could also be said to be broad-shouldered and round-waisted.

Looking at my little arms and legs, I am only 5.5 feet tall (174), which is a head shorter than Zhao Jun. When it comes to really fucking, the guards are hundreds of meters away, but these old men around me can pull him off. Do you live in Zhao Jun?

So I hesitated for a while, but still didn't take action.

Um.

We are Renzong, we must be generous!

Zhao Zhen took several deep breaths before calming down.

Fan Zhongyan replaced Yan Shu as the field controller and quickly changed the subject: "Let's continue talking about mathematics."

Zhao Jun continued: "Mathematics is not only the foundation of science, but also the backbone of industry. If we want to carry out the industrial revolution, we need the entire country's national quality to have excellent mathematical skills."

"In the early years, our country could be said to have been completely impoverished. It was only because of the large number of patriotic scientists who studied in the West that they returned home, and with the help of the big brother of the Soviet Union, that we transformed from an agricultural country into a heavily industrialized country in just a few decades."

"Although these patriotic scientists come from various fields, what they have in common is that they all have very good mathematical abilities."

"Qian Xuesen has a doctorate in aviation and mathematics. Deng Jiaxian has been studying mathematics and English since he was in high school. Hua Luogeng is the vice president of the Chinese Academy of Sciences and a world-renowned top mathematician."

"So it is precisely because of the construction of these patriotic scientists that we can have a large heavy industry foundation, and under the compulsory education for all, we have many high-quality talents. Today, it is the world's largest industrial country, leaving even the Eagle Sauce behind. ”

"The only pity is that we started too late. The West entered the Age of Discovery in the 15th century and colonized the world. In addition, the Renaissance and Enlightenment liberated the mind, opposed feudal superstition, advocated scientific development, and cultivated scientific soil. Started the Industrial Revolution two hundred years ahead of us.”

"Through the Industrial Revolution, Western scientific and technological power developed rapidly, with strong ships and powerful guns, and colonization by force. They quickly monopolized global trade and completed primitive capital accumulation."

"Our country became a semi-colonial and semi-feudal society in the late Qing Dynasty and missed this opportunity. As a result, after World War II, Yingxiong divided the world, and then Maoxiong disintegrated. Yingjiang's family became the dominant one, forming today's world of one superpower and multiple powers. pattern."

"But even so, we have grown stronger step by step, surpassing many Western developed countries, ranking second in the world in comprehensive national strength, and completing many world-renowned achievements. All this is because our country has a large number of science and engineering talents , there are a lot of excellent math experts.”

"So if children study mathematics well and lay a foundation in science, they will be admitted to a good university in the future and will definitely find a good job after graduation. Uncles, learning is very important. How much money can you make when you go out to work? Only by studying can you have more success. Good future."

Zhao Jun talked nonstop about the role of mathematics. As the leader of science subjects, mathematics plays an important role.

He hopes to make the villagers aware of the importance of studying. He hopes that parents in Nini Village will not prevent their children from going to school like most parents in Daliangshan, and let them go out to work when their children have not graduated from junior high school. It can give children a brighter future.

But all his hard work was obviously in vain. Everyone was thinking about how to use science to make Song Dynasty powerful. Zhao Zhen was even more curious and asked: "Teacher Zhao is a pillar of the country. I wonder how much his monthly salary is now?"

Zhao Jun: "."

This man named Wazhamuguo was the only young man in the village, and he found that he disliked him more and more.

It’s really hard to mention which pot you don’t mention.

"I found out why your little comrade's ideological consciousness is so low? This is called dedication. Do you know dedication?"

Zhao Jun thought of his 600-yuan education subsidy and shed tears in his heart. He even said heartbrokenly: "As a party member, I volunteer to teach. The state provides food, clothing, housing and transportation. It's just a matter of asking for money."

My ideological awareness is low?

Zhao Zhen was unhappy again and said, "Didn't Teacher Zhao say that if you study well, you can make more money? What's wrong with me asking the teacher about his income?"

"Not every part of the country is prosperous and powerful. Isn't our village a poor village?"

Zhao Jun responded: "It is precisely because of poverty that high-quality talents like me are needed to come here and help everyone get rid of poverty. I am here to develop education. This is a task assigned to me by the organization. You little kid Comrades, don’t always be interested in money. I heard that you are the only young man in the village who has skills and skills. It’s better to go out and work instead of idle in the village all day.”

Oops, you said I am idle?

Zhao Zhen had a bad temper, gritted his teeth, stamped his feet fiercely, and then sat there motionless, folding his hands and getting angry.

"Yes, yes, Teacher Zhao came to our village to teach. It is a task sent by the state. It is commonplace to ask for money."

Lu Yijian quickly changed the subject and said: "Speaking of which, Teacher Zhao, do you think if we were in ancient times, such as the Song Dynasty, could we have developed a level of mathematics that would lead to the industrial revolution?"

"Ancient?"

Zhao Jun thought for a while and said: "I'm afraid it will be more difficult."

"Why?"

“Because of the system, the system and the natural environment.”

"Can you tell me?"

Lu Yijian asked, and everyone was also curious.

Zhao Jun said: "Let's talk about the system first. In fact, the level of mathematics in our ancient times was actually quite high. "Zhou Bijun Jing" already has square roots, and "Nine Chapters of Arithmetic" and "Nine Chapters of the Book of Numbers" even have algebra, Geometry, rational numbers, irrational numbers, pi, and trigonometric functions were more than a thousand years ahead of the West at the same time, and were not surpassed until the Renaissance.”

"Then why was the West able to develop the industrial revolution first and overtake others in a straight line in the fields of mathematics, physics, chemistry and other fields, accumulating huge advantages?"

"It's because our country's ancient science did not form a system. For example, in mathematics, Chen Zi in "Zhou Bijun Jing" answered Rong Fang's question and mentioned using the Pythagorean theorem and square root to find the distance from the sun, but there is no square root procedure, only square root. Say "Prescribe a prescription to eliminate it."

"Almost all the content in "Nine Chapters of Arithmetic" and "Nine Chapters of the Book of Mathematics" is about how to calculate, and the answer can be obtained directly, and basically does not involve proof of principles. When Zhu Shijie listed the equations in the stacking formula, he did not derive it, but It is quoted directly as common sense, which shows that the mathematical system at that time was not perfect and the intermediate derivation part was missing.”

"To put it simply, one plus one equals two, everyone knows it. But why one plus one equals two, no one in our ancient times explored it, but it became a common sense. This is definitely not possible. Mathematics is based on The discipline of logical reasoning. It establishes a rigorous proof system of mathematical theorems and inferences through logical deduction and induction, and cannot simply give results. "

"So although our ancient mathematics level was relatively high, the intermediate derivation and proof processes were often omitted, making it very difficult for ordinary people to learn and not easy to spread. Even those who specialize in mathematics, everyone Only the beginning and the end are known, without the intermediate steps.”

"In mathematical deduction, the derivation process accounts for a higher score than the correct answer. If the math test only writes answers, you will be given two points at most. Therefore, ancient Chinese mathematics only has questions and answers, without the intermediate proof link."

"This seriously caused a major deficiency in the mathematical system, and not only mathematics, but also physics and chemistry. We also lacked the spirit of inquiry in ancient times. When Newton saw an apple falling, others would naturally think that this was common sense. But he could think of why the apple fell. What about landing? Then he discovered the gravity of the earth and derived the law of universal gravitation.”

"So in summary, if our ancient mathematical system wants to be perfected, mathematicians must have the spirit of inquiry to explore why this formula is true. Only by laying a good foundation in mathematics and laying a solid foundation can it be possible to extend to physics and chemistry , laying the foundation for the industrial revolution.”

In fact, the level of mathematics, physics, and chemistry in ancient China has always been very high. In the field of mathematics, the achievements of Liu Hui and Zu Chongzhi were not even matched by Westerners of the same period.

In terms of physical astronomy, Liu Hong, the astronomer of the Eastern Han Dynasty, perfectly calculated the time of a year. There are also complete mechanical pulleys, levers, lathes, and hydraulic facilities. Even the first manned aerospace rocket was from the Ming Dynasty. Tao Chengdao, the "Wanhu Mountain" on the moon's surface is named in commemoration of Tao Chengdao.

Not to mention chemistry, gunpowder, petroleum, copper making, cinnabar, steel making, iron smelting, etc. are all recorded in "Mengxi Bi Tan" written by Shen Kuo of the Song Dynasty.

So why couldn’t ancient China develop an industrial revolution when its technology was far ahead of the West?

The famous economist Lin Yifu believes that this is a reflection of the differences between China and the West in their treatment of science and technology. The most typical example is that the West focuses on experimental scientific methods, while the East focuses on practical value.

For example, when Newton saw an apple falling to the ground, he would think of gravity. Others will only see an apple, pick it up and eat it.

This is, at best, pragmatism; at worst, it is a lack of theoretical inquiry. People only saw the apple falling to the ground, but they didn't know why the apple fell to the ground. This is an important shortcoming for scientific research, because science itself requires exploration.

Therefore, Zhao Jun believes that if Lin Yifu's views are accepted, it will be difficult for ancient China to form a scientific system.

Moreover, Lin Yifu's point of view is also correct. Ancient Chinese science indeed only had a beginning and an end, and seriously lacked the intermediate derivation and proof process. Such a incomplete and incomplete system would make it difficult to establish an industry.
