Chapter 1168 Postscript 24·Mathematical research is a bit too advanced
Chen Duan is thirty-two years old.
He passed the national examination at the age of twenty and was once astonishingly talented. Since then, he has repeatedly failed the examination and his status as a candidate has expired. He will take the examination again this year.
In the past two years, I moved to Luoyang with my grandfather just to visit famous teachers in the capital and see if I can improve my knowledge.
"My father, brother, and uncle are not in Beijing, and the courtyard is usually empty. You brothers are just here to keep me company." Chen Duan led them to the backyard. "Brother Xian's room has been tidied up a long time ago. You can sleep in it after moving out the bedding."
.Your four healthy servants can sleep outside."
Xie Yan said: "Thank you, Brother Ten, for taking the trouble."
Chen Duan smiled and said: "It was all arranged by my grandmother, how can I be so careful?"
"Then I must thank my grandmother." Xie Yan said.
Chen Duan said: "You pack your luggage and take a shower first. I will drink tea with your elder brother and wait for you."
Xie Hong also said: "Juro is a warm-hearted person. You are still very young. You regard this place as your home."
"Hahaha, this is true, I really like to hear it." Chen Duan laughed.
Xie Yan really wanted to take a good bath. Although the high-end carriage of the train was farther back, he still smelled soot all the way after opening the window.
He bid farewell to his two brothers, asked his servant to carry the box containing the scale into the house, and then began to look for his change of clothes.
In the bedroom, a maid was making the bed and folding the quilt.
When the maid saw Xie Yan, she quickly stopped what she was doing, knelt down and saluted and said, "Long-term blessings to you. My name is Yan Yan, and I live in the next room. If you have anything to do, just give me your instructions."
Xie Yan cupped his hands and said, "Thank you, sister."
Yanyan was about seventeen or eighteen years old. She was neither beautiful nor ugly, but she was very quick at work. She grabbed the edge of the bed sheet with both hands and shook it. Most of it had been laid out: "The kitchen is already heating water. If the husband wants to take a bath,
Please wait a moment."
"No rush."
Xie Yan took out the key and opened the box to check whether his scale was damaged.
The balance has long been disassembled, and each part is wrapped in silk. Outside the silk is cotton, and then wrapped in cotton cloth.
Repeat this process of padding and wrapping it in several layers.
The box was also filled with cotton to protect it from the bumps and bumps on the train.
After taking it apart one by one and checking that there was no damage, Xie Yan rewrapped the various parts of the balance.
After doing this, Xie Yan stood up and turned around, seeing Yan Yan standing nearby.
"What are your orders, Sir?" Yan Yan asked.
Xie Yan said: "Go and do your work. Call me after the hot water is boiled."
Yanyan bowed and left.
The eldest brother Xie Hong suddenly walked in: "Did you bring it that day?"
Xie Yan said: "It's all in the box. I just checked it and it's intact."
Xie Hong said: "Your molecular paper was published in the last issue last year. I don't know about other places, but it really caused huge controversy in the East and West Beijing. Most scholars are completely opposed to the views in the paper, and a few
Scholars agree with some and oppose some."
"It would be good if a few people agree," Xie Yan was very satisfied. "After the invention of the long-arm damping balance, have chemists used it to verify molecular theory?"
Xie Hong said: "I don't understand chemistry, so I can only try to help you find out. That long-arm damping balance is indeed useful. I heard that many physics and chemistry experiments have achieved breakthroughs. But if it is used to study molecules and atoms, it seems that the accuracy
It’s still a little bit worse.”
"When I take out this scale, they can shut up." Xie Yan was full of confidence.
Xie Hong smiled and said: "Actually, this Spring Festival, there is another scholar who was scolded worse than you."
Xie Yan asked curiously: "Are there any masters?"
Xie Hong said: "The scholar's name is Wang Daqing. He has just passed his forties and is a professor at Nanjing Taixue. He studies mathematics, physics and astronomy. He submitted a manuscript to a mathematics journal early last year, and it was rejected many times.
I was so angry that I stopped teaching and asked for leave to come to Luoyang from Nanjing."
"And then you published it to him?" Xie Yan asked.
Xie Hong shook his head: "The Mathematical Society still refused to publish it, saying that his paper was too absurd. Wang Daqing was so angry that he found a printing house in Luoyang and printed the paper at his own expense. Then he took it to the Royal Society and Luoyang
In Taixue, he distributed gifts to everyone he met, and the contents of his papers aroused huge criticism."
Xie Yan was even more curious: "What on earth did he write?"
Xie Hong said: "I'm not good at mathematics, and I don't understand complicated things. It seems to prove that the fifth postulate of geometry is unprovable. On this basis, I derived a lot of results and claimed to have established a kind of starry sky geometry."
After all, Zhu Guoxiang and Zhu Ming and his son were not professionals, and many basic theorems and formulas were omitted.
At that time, a large number of books were brought back from Byzantium, Fatima (Egypt), and Seljuk, including complete Euclidean geometry.
The mathematicians of the Ming Dynasty took over all the Euclidean geometry and combined it with the mathematics of the father and son.
The five postulates of Euclidean geometry naturally spread during the Ming Dynasty.
The first four postulates are all simple and clear.
And just last year, Wang Daqing proved that the Fifth Commune has the derivation of the first four Communes. This is not the most outrageous. In the process of proving it, he deduced a lot of counter-intuitive content, and also used this to build a system and claimed to have created a
New geometry.
To sum it up simply, it is to dig into the foundation of traditional geometry.
"Where can I get his paper?" Xie Yan asked.
Xie Hong said with a smile: "I went to attend a literary meeting today and was handed a copy by Wang Daqing. He stayed in Luoyang even during the Spring Festival and actually went to a literary meeting for liberal arts students to distribute papers."
Xie Yan said: "I want to take a look."
"Lang Jun, the hot water is ready!" Yanyan shouted outside the door.
Xie Hong stood up and said: "After you take a bath, follow me to see Chen Shangshu and have dinner with them. After dinner, I will give you the mathematics paper."
Xie Yan took a change of clothes to the bathroom, and Yan Yan followed him the whole time, waiting outside the bathroom to help him fill up the water.
Xie Yan finished washing without adding water.
When he was taken to the dining room, everyone else had already arrived.
In addition to Chen Duan and Xie Hong, there are also Chen Wenzhao, Minister of the Ministry of Industry, and Chen Wenzhao's old wife Xia Shi and his old concubine Zhang Shi.
Chen Wenzhao's hometown is in Shaanxi, and none of his other descendants came to the capital with him.
Xie Yan's deceased grandfather was a Jinshi in the same year as Chen Wenzhao, and they were interns in the same department. Later, because they dared to speak out and remonstrated, the two of them were demoted to despised places.
This relationship seems to be very strong.
But in fact they were not very close, because the total time they spent together was only half a year, and they went their separate ways after that and didn't see each other very often.
"Junior Xie Yan, pay homage to the old husband and the old lady!" Xie Yan went over and saluted the three elderly people. The two old ladies smiled and nodded.
"Sit down and eat quickly. There is no need to be polite at home."
Chen Wenzhao also had a smile on his face. He asked Xie Yan to sit down and said, "Your grandfather and I have known each other for many years. Although we didn't meet much, we still corresponded every year. If he could live a few more years, he would see his grandson sixteen
If you become a Bachelor of Jasper at the age of 10, you will definitely be able to live with great joy and die without any regrets!"
Xie Yan said modestly: "It's just a fluke."
Chen Wenzhao smiled heartily: "I was also a Li Jinshi back then. The Medicine Jade Bachelor may be lucky, but the Jasper Bachelor is not a lucky person."
Chen Duan took the opportunity to make the old man happy: "When my grandfather was young, he also published a paper in a mathematics journal."
Xie Yan quickly handed over his hands: "Disrespect, disrespect."
This was something Chen Wenzhao was very proud of. He laughed and waved his hands: "It's just an ordinary mathematics paper. It doesn't deserve much praise. It didn't even get into the Bachelor of Medicine and Jade."
Xie Hong said: "That's because my old husband was busy with official duties and was busy serving the country and loyal to the emperor. He had no time to study mathematics. Otherwise, at least he would still be a bachelor of roses by now!"
Chen Wenzhao smiled even more happily, pointed at Xie Hong and said, "You are very clever, and you have the legacy of your grandfather."
Xie Yan asked: "Isn't my grandfather a serious Taoist scholar?"
"He's so serious! One time he dragged me to..." Chen Wenzhao suddenly shut up in the middle of the sentence, waved his hands and said, "Forget it, it's better for the dead, don't tell the embarrassing things about him back then."
Xie Hong and Xie Yan could only smile and say nothing.
Who hasn’t been young and frivolous?
Chen Wenzhao said: "The Society of Physics has written to the Ministry of Industry, telling you about the damping phenomenon you discovered. This thing is very promising, especially when applied to sea ships. I have signed and allocated research funds."
Xie Yan said: "If the building is built to a hundred stories in the future, especially if it is built in a coastal area where there are typhoons, then the towering building will also need to use dampers. Well... to prevent the building from being blown down by the wind."
"Hahaha!"
Everyone present laughed, including the two old ladies.
The old lady Xia said: "If you build a building with a hundred floors, the people who live in it may not be gods."
The old lady Zhang then said: "Mortals can live in it, but I'm afraid the floor is too high to climb. When you get down from the 100th floor in the morning, it's probably time for lunch. Climb back to the 100th floor, just in time for dinner.
sleep."
This was said in a funny way, and everyone laughed again.
Xie Yan also laughed.
The rest was all about family matters. Mrs. Xia stared at Xie Yan, looking left and right: "He is a talented person and also has extraordinary knowledge. It's a pity that my granddaughters are either married or engaged."
Mrs. Zhang said: "The Qin family has two granddaughters who are a perfect match."
Xia Shi shook her head repeatedly: "No, no. The two granddaughters of the Qin family are both wild girls who are used to going crazy. The sixth son of the Xie family is a royal bachelor, so he should be matched with someone who is quiet and virtuous."
"How is the little girl from the Shao family?" Mrs. Zhang asked.
"Which Shao family?"
"Fufeng Shao family, we returned to Beijing more than three years ago and we were guests at the Shao family."
"I remembered. The young lady from the Shao family is really nice. She is gentle and quiet. She is a good child who is knowledgeable and courteous. I will write to you some other day to ask if the young lady from the Shao family is engaged."
"..."
The two old ladies became more and more animated as they talked.
Chen Wenzhao was unhappy: "This is all this woman knows. Xie Liulang has a bright future. Why should he be anxious about getting married at such a young age?"
Mr. Xia said: "No matter how knowledgeable you are, you are still a human being. To be a human being, you need to get married and have children. With a good wife to take care of the chores at home, Xie Liulang will be more comfortable with his studies."
After Xia finished speaking, she asked the three young people at the dinner table: "Do you think this is true?"
"Yes, yes."
"It should."
"The old lady is right."
The three young people quickly followed suit.
Mrs. Xia then turned to her husband: "You see, they all think I am right."
Chen Wenzhao was too lazy to argue: "Yes, yes, you are right. This is Xie Liulang's marriage. Maybe his family has already arranged it, so don't write random letters to the Shao family. By then, Xie Liulang's family has negotiated a deal.
How should you face the Shao family?"
Xia was speechless and stopped talking.
Xie Yan heard that it was interesting. The old couple were very easy-going, and they did not regard him and the eldest brother as outsiders.
After dinner and a few chats, everyone went back to their rooms.
Xie Hong also brought over the mathematics papers that Wang Daqing had printed and distributed at his own expense.
Xie Yan returned to his guest room and read carefully under the light.
He was good at high school mathematics and his knowledge of geometry was acceptable, but in the eyes of mathematics majors he was a scumbag.
Wang Daqing's paper starts with the assumption that multiple parallel lines can be drawn through a point outside a straight line.
That is, assume that there are multiple parallel lines in a straight line.
Xie Yan was stunned on the spot and felt that his brain was a little weak.
Soon he realized that this was not fucking Euclidean geometry, but the legendary Roche geometry.
I haven’t learned anything!
I only came into contact with some superficial concepts in high school geometry textbooks.
At that time, the high school mathematics teacher was in the mood to brag and casually told a few short stories about Gauss and Lobachevsky.
The reason why Xie Yan remembers it clearly is because his high school mathematics teacher said that Einstein's theory of relativity could not be expressed in mathematical tools, and in the end he relied on Roche geometry to solve the problem.
I don’t know if it’s true, but it doesn’t stop Xie Yan from thinking that Luo Shi is awesome.
The Ming Dynasty's academics were too lame, and mathematical research seemed a bit too advanced.
