Xu Guangqi kept his promise. After returning to the post house, he went back to his room, changed into casual clothes, and ran to Su Hao's room holding a candle. Su Hao sent Chen Guanyu out to buy some pastries, fruits, etc.
In order to entertain Xu Guangqi, the two sat on both sides of the table and started talking freely.
Without the interference of Chen Dao and Xiong Ji, the conversation between Su Hao and Xu Guangqi went much deeper. Xu Guangqi is a person who likes to delve into research. He has read many ancient scientific and technological works before, especially in mathematics. Su Hao has some experience.
His stomach was full of modern mathematical knowledge. Just mentioning a few words made Xu Guangqi feel as if the clouds had suddenly cleared up. Many mathematical problems that had troubled him suddenly became clear at this moment.
"The way of arithmetic of this Yi people is really unique, and it is very different from our Chinese arithmetic. Brother Yu feels that these Yi people's arithmetic has four things that are not necessary, that is, no need to doubt, no need to guess, no need to try, and no need to change. Unlike our Chinese.
Arithmetic is just a monstrous art, and it is fallacious to say that there is some magic in numbers." Xu Guangqi said.
Su Hao didn't know what to say. In fact, ancient China had some very brilliant mathematical achievements and was at the forefront of the West in many aspects. However, compared with Western mathematics, ancient Chinese mathematics lacked a set of overall principles that could govern the overall situation.
The logical system and various mathematical knowledge are fragmented, and the further they develop, the harder it becomes to justify themselves. Some magicians rely on mathematical knowledge to play tricks and turn it into a metaphysics, which makes the development of mathematics go astray.
On the other hand, Western mathematics has established a logical reasoning system based on axioms, postulates, and definitions since the time of Euclid. Later generations have continued to improve this logical system, allowing it to continue to flourish and develop.
.In modern times, the impact of the differences in mathematical thinking between China and the West has become more obvious, and the decline of traditional Chinese mathematics is irreversible.
In the parallel world, Xu Guangqi was the first person in ancient China to systematically come into contact with Western mathematics. His translation of "Elements of Geometry" completely subverted the traditional Chinese mathematical concepts and introduced Western mathematical ideas into China. In fact, Xu Guangqi was very important to Chinese traditional mathematics.
The critical consciousness of mathematics had already appeared before he came into contact with the Elements of Geometry. At this time, when he talked with Su Hao, his feeling became even stronger.
"Instead, I think the Yi people's theories you have learned should be sorted out as soon as possible and printed into books for the reference of students all over the world." Xu Guangqi said eagerly.
Facing Xu Guangqi's enthusiasm, Su Hao felt guilty. As a time traveler, he should indeed sort out and promote this kind of knowledge that transcends the times. All this knowledge can be transformed into productivity
.
The Ming Dynasty was the most economically prosperous dynasty in ancient China, but even for such a dynasty, when faced with great disasters, the people were still miserable, and people starved to death almost every year. If there were some advanced
Knowledge can be used to guide production in all walks of life. With the hard work of the people of the Ming Dynasty, it should not be difficult for people all over the country to live a life of food and clothing, right?
Unfortunately, during the six months since Su Hao traveled across time, he has been in a state of involuntary control. He has done a lot of things, but most of the time he just uses his knowledge to solve the problems at hand, and
He did not organize and impart his own knowledge. In addition, because he was worried that this advanced knowledge would bring trouble to himself, he sometimes deliberately concealed this knowledge. For example, regarding the smelting technology of high manganese steel, so far, except for Hao
Basically no one else knows about it, let alone applies it in practice.
"Brother Xu, I also have my own difficulties." Su Hao said, "What I have learned is foreign knowledge and belongs to the heretical sect. If I publicize it in a big way, I'm afraid it will attract criticism."
"What's there to be afraid of?" Xu Guangqi said, "If Gai Gai is busy with his affairs and has no time to sort them out, Brother Yu is willing to do it for him. As long as Gai teaches these doctrines to Brother Yu, Brother Yu will compile them into a book and spread them widely.
"
Su Hao said: "Brother Xu, aren't you going to Shaozhou to teach? How can you have time to do these things?"
Speaking of this, Xu Guangqi felt a little sad. He sighed and said: "Well, to put it another way, I still have no way to make a living. It's really ridiculous to think about these things. It's just a pity that I have such a good knowledge.
People know it. There is no one in the world who does not want to learn these doctrines."
Su Hao's eyes suddenly lit up and he asked: "Brother Xu, have you made an agreement with the other party about going to Shaozhou to teach? If there are other opportunities, are you willing to try it?"
Xu Guangqi said: "This teaching position in Shaozhou was found for me by an uncle of my clan. If I don't go, it's okay. I can write a letter to him explaining the matter, but I don't know what to say.
What is opportunity?"
Su Hao said: "Mr. Wu Zhicheng, the professor of Longguang Academy in Fengcheng, is my younger brother's friend. He is also very interested in the learning of the Yi people. My younger brother once compiled the Yi people's theories he learned into three small books on mathematics, theory and chemistry.
The brochure is given to Mr. Wu. If Brother Xu is interested in learning Yi people's theory, I would like to write a letter of recommendation to Brother Xu. Brother Xu will take this letter to Longguang Academy to find Wu Jiaoyu, and he will definitely be able to arrange a teaching position for Brother Xu.
, although I dare not say that I can live in fine clothes and fine food, I can still achieve it by barely covering my belly.
Brother Xu can discuss the Yi people's theory with Mr. Wu in Longguang Academy. In addition, there are students in the academy such as Ma Yu and Jiang Yida, who have studied Western arithmetic with my younger brother. Brother Xu will be with them.
What is gained.”
"Is this really possible? Brother Yu is willing to go." Xu Guangqi responded happily. For him, it is the same wherever he teaches. If he goes to Fengcheng, he can have a full meal and at the same time, he can teach a group of students.
How could he refuse such a good thing to discuss Western mathematical knowledge together?
Su Hao was extremely excited when he saw that Xu Guangqi agreed. Xu Guangqi's talent should be higher than that of Wu Zhicheng, Ma Yu and others. If he is willing to stay in Longguang Academy to study mathematics, physics and chemistry, then he will not worry about his knowledge.
There is no one to pass it on. As for teaching positions and the like, Su Hao is just talking about it. Su Hao is now a man who owns several properties. It is not difficult to support Xu Guangqi.
Su Hao wrote two letters on the spot and asked Xu Guangqi to bring them to Wu Zhicheng and Lu Xiuer respectively. The first letter asked Wu Zhicheng to take Xu Guangqi in to teach in the academy, and the latter letter asked Lu Xiuer to use money to support Xu Guangqi. He must be allowed to study in the academy.
Fengcheng has no worries about food and clothing, and it is best to be happy and not miss Shu.
Xu Guangqi accepted the letter and accidentally looked up out of the window. He couldn't help but smile. It turned out that there was some light outside the window, and the two of them had talked all night long without knowing it.
"Listening to your words is better than ten years of reading. My brother Gai is still young, but his knowledge is extraordinary. Zi Xian used to think that he had some experience, but when he compared it with Gai, he realized that he was a frog in the well." Xu Guangqi said.
concluded with emotion.
Su Hao waved his hands repeatedly: "What Brother Xu said is really embarrassing to me. It was just a coincidence that I got guidance from a missionary for a few days. In addition, I also have some experience of my own. Brother Xu is very talented. If he can train
The success of this Yi people’s theory will definitely be a hundred times that of my younger brother.”
"Gai Zhi is humble." Xu Guangqi said, "Brother Yu said goodbye first, let Gai Zhi rest for a while. Didn't we have some more exercises today? After chatting with Gai Zhi, Brother Yu was anxious to see what the barbarian was doing.
What’s so subtle about the art of earth?”
Su Hao sent Xu Guangqi away and went to bed for a short sleep. It was already dawn. He got up, washed and changed clothes, walked out of the room, and saw Chen Dao, Xiong Ji, Xu Guangqi and others had packed up and were waiting for him. Xu Guangqi also
I stayed up all night like him, but my face showed no signs of fatigue, on the contrary, there was still some excitement.
Several people left the post house and came to the tent camp set up by Kanyu Camp. The soldiers of Kanyu Camp got up earlier than them. Even during the march, Hao Tong and Deng Kui still led them outside the town.
After walking a few miles, I came back and practiced sword and gun for a while. I was eating at the moment and was preparing to conduct a surveying and mapping exercise around Qiaoshe Town.
Some soldiers had already brought rice porridge, rice cakes and side dishes to Su Hao and others, which were all made by the camp. Su Hao invited everyone to eat together, and then ordered them to line up. The soldiers stood in small flags.
A square formation, horizontally and vertically, everyone had a sullen face, straight waist, and a neat military appearance. Not only Chen Dao looked at it and nodded secretly in amazement, but Xiong Ji and Xu Guangqi were also amazed.
"This is clearly an army. Where is the people?" Xu Guangqi whispered to Su Hao.
Su Hao also replied in a low voice: "Brother Xu, I'm sorry, I concealed something yesterday. My identity on this trip is from a hundred households under the Nanchang Guard, and these soldiers are my subordinates."
"It turns out that Brother Su is actually a member of the army. I'm disrespectful." Xu Guangqi said, not knowing whether he was surprised or regretful.
After the formation was completed, Hao Tong ran over to ask Su Hao for instructions on today's mission. Su Hao turned to Chen Dao and said, "Chief Chen, how about you give the soldiers a lecture first?"
Chen Dao smiled and waved his hands and said: "Forgive me, I don't know how to lecture you. Just do it as usual and don't worry about me. I have already said that I am just going to Yunnan with you."
Come on, Su Baihu is in charge of military affairs."
Su Hao knew Chen Dao's temper and did not force it, so he gave orders to Hao Tong and Deng Kui, asking them to start arranging each small flag to carry out surveying and mapping work. Hao Tong had already arranged for people to run around the surrounding area on the first day.
After drawing a sketch of the surrounding area, he called the flag officers over and assigned tasks to them. After receiving the drawings assigned to their flags, each flag officer returned to the team, carrying the 10 soldiers of the flag.
, carrying various instruments and set off.
"Mr. Chen, do you think we should go and see it together or separately?" Su Hao asked Chen Dao.
Chen Daodao: "Let's split up so that we can follow more teams. If Brother Xiong and Brother Xu want to watch, why don't they each go with one person?"
"I'll follow Su Baihu." Xu Guangqi said first.
"Forget it, I'll just go with Brother Xiong." Chen Dao said with a smile. (To be continued. Please search Piao Tian Literature, the novel will be better and updated faster!)
