Fourth, Chen Xuan

Jiang Shuiyuan went back to the room to make up for sleep, and he didn't know how Huang Tongyuan got in touch. When I went downstairs after lunch, I saw Uncle Ge and a young man with a short figure standing next to the Jingshi Flying Sedan chatting.

Uncle Ge greeted him with a spring breeze on his face: "Welcome to the capital!" Come on, let me introduce you first, this young talent is my college classmate Chen Xuan, who also studied mathematics, but he has a smart head and knows that there is no future in mathematics, so he changed his career early to do speculation and business. Come, Jiang Shuiyuan, call uncle!"

Jiang Shuiyuan looked at Chen Xuan, who still had pimples on his face, but he couldn't say the word "uncle". Chen Xuan's face was full of astonishment: "I'm a dumbfounder!" Gezi, I haven't seen you for a long time, and your son is so old?"

The water source of the river can't help but be full of black lines.

The corners of Ge Juntian's mouth twitched: "I said four-eyed dog, you have lost your brains by making a fund, right? You don't want to think about it, if I want to have a son as big as him, I can't get married and have children from the time I wear open crotch pants? Am I so talented?"

Chen Xuan patted his head with a sudden realization: "I'll just say! You look so stumpy, how can you have such a handsome and compelling son?"

Ge Juntian hurriedly explained to Huang Tongyuan and Jiang Shuiyuan: "Don't look at him as honest and honest, he is actually wilted and wilted. When he was in college, his classmates nicknamed him 'Four-Eyed Dog'. It is said that there is only the wrong name, not the wrong nickname. Guess what a four-eyed dog means?"

Huang Tongyuan said: "Could it be that Mr. Chen was wearing glasses at that time?"

Ge Juntian looked at Jiang Shuiyuan: "Jiang Shuiyuan, you can talk about it!"

Jiang Shuiyuan replied: "Chen Yucheng, the king of the Taiping Heavenly Kingdom, is short in stature, agile in his movements, fair in face, and has black moles under his eyes, which looks like four eyes from a distance, so he is called 'four-eyed dog' by the Qing army." Hu Linyi, one of the four famous ministers of Zhongxing, once said: 'The elite of thieves, only four-eyed and one-eared, why should he worry!' Dai Dejian commented in "Penglai Pavilion Ruler" that he was "cunning and outstanding, good at destroying great enemies" and "rare in modern times". I guess it's because Mr. Chan has the same surname as King Ying, and he is not tall and resourceful, so he is called by the nickname of King Ying. ”

Ge Juntian said: "Although the meaning is similar, who of us knew Chen Yucheng and Hu Linyi at that time? The reason why he was given such a bandit name is because there is a popular saying among the people, called 'Four-eyed dog, don't bite, secretly mouth'." You see what that means, right?"

Chen Xuan punched Ge Juntian: "Hey, hey, is there such a thing as you who will expose people's secrets as soon as they meet?

"Do you still have a Weiguangzheng image?" Ge Juntian smiled narrowly, "But in front of the beauties and juniors, I still have some face for you." Then call you another nickname, 'Chen Leisong'? Jiang Shuiyuan, do you know what 'Chen Leisong' means?"

Jiang Shuiyuan blinked: "Is it related to the famous mathematician Uresunson in the Moscow School?"

"That's right, but I'm not to the point, go on. ”

"Is it because Mr. Chen is as interested in dimensional number theory as he is about Ureson?" Or is it because Mr. Chen is not interested in mathematics and has made up his mind to change his career early on, and his scientific career in mathematics is as short as Oreson?"

Ge Juntian laughed: "Okay, good, he really deserves to be my student! But if you look at Chen Tuhao's appearance, you know that he can't play advanced dimensional number theory." His favorite is martingale theory and game theory, and he is obsessed with the Kelly formula and the Black-Scholes formula and can't extricate himself, so the title of his college graduation thesis is "The Fractional Black-Scholes Model and Its Application in Mathematical Finance". After graduation, he simply went all the way to the dark, and all the way to his grandmother's house, which can be regarded as a complete parting of ways with mathematics!"

Chen Xuan retorted: "Don't take bean bags for dry food! Financial mathematics is not mathematics?"

"According to what you say, astronomy still belongs to literature, isn't it?" Ge Juntian finally began to introduce Huang Tongyuan, "This petite and lovely intellectual beauty is my colleague in Huai'an Fu Middle School affiliated to Jingshi University, named Huang Tongyuan, who teaches biology. Do you know what her biggest characteristic is? It's not that she's beautiful, but she's very gentle. Whisper, our Teacher Huang is Yunying unmarried and waiting for the boudoir, you kid must seize the opportunity!"

Chen Xuan's eyes suddenly lit up, he tried to raise his body, and then stretched out his hands: "Teacher Huang, I am fortunate to be happy!"

"I'm sorry, I'm going to trouble Mr. Chen today!"

Ge Juntian pointed to Jiang Shuiyuan again and said, "This little handsome guy is a student I teach, and his name is Jiang Shuiyuan." - Chen Leisong, have you noticed that anyone with 'Yuan (Yuan)' in their name is generally very good-looking. - Do you know why I chose him to be my heir, and in addition to being as smart as me, he is as handsome as I am. ”

Chen Xuan sighed: "After so many years, your brazenness is still the same as always!"

"Get in the car!"

Ge Juntian waved his hand domineeringly, and then took the lead in the co-pilot's position. Chen Xuan is a driver, needless to say. Huang Tongyuan sat in the back row with Jiang Shuiyuan, and after sitting down, she couldn't help but ask in a low voice: "Jiang Shuiyuan, why do you all say that Uresun's scientific research career is very short?"

Although Oreson has made important contributions to topology and is also one of the founders of dimensional number theory, in terms of fame and contributions, he is still far inferior to Euler, Gauss, Riemann and other top bosses, nor as good as Lagrange, Leibniz, Hilbert and other great gods, and even inferior to academic leaders such as Cauchy, Lee, Klein, Cantor, etc., at most he is a 1.5-rate mathematical elite. Not to mention that ordinary people don't know, even ordinary mathematics undergraduates, few know about it.

Jiang Shuiyuan immediately explained: "Uresun, a famous mathematician from the Rakshasa Kingdom, entered Moscow University at the age of 17 to study physics, but gradually became interested in topology. After graduating from university at the age of 21, he stayed on as an assistant to Professor Luzin, a central figure in the Moscow School of Mathematics. At the age of 23, he obtained a charter teaching qualification and worked as an assistant professor at Moscow University. On August 17, 1924, he drowned at the age of 26 while swimming on the coast of Brittany, Florida. From the end of his university graduation to the end of his life, his scientific research career was only 5 years, which can be described as short, but he made good achievements, including the establishment of the Uresson degree quantitative theorem and the Ureesson lemma, two basic results of topology. His name is also used in the 'Menje-Uresund Dimension' in honor. ”

Huang Tongyuan smiled bitterly: "It seems that if I don't know a little about advanced mathematics and the history of mathematics, I can't chat with you happily." ”

Jiang Shuiyuan shook his head: "This is called a specialization in the art industry. You are a student of biology, and you compare your mathematical knowledge with the two of them, isn't this attacking each other's strengths with your own shortcomings, and looking for abuse by yourself? Think about it another way, if we talk about the content of a slightly more professional biology competition, I guess they will also be confused!"

"Really?"

Jiang Shuiyuan leaned over and patted Uncle Ge on the shoulder, and asked politely, "Teacher Ge, do you know what major changes have taken place in the classification of the superfamily of apes in the past hundred years, and what is the basis for this?"

"Huh......?"

Seeing that Ge Juntian was killed by Jiang Shuiyuan cleanly and neatly, Huang Tongyuan finally regained some confidence and chatted with Ge Juntian and Chen Xuan about the scenery of the capital. Among the three of them, two teachers and a fund manager belong to the masters who can speak well, talking and laughing along the way, and by the time they get off the bus, they can almost cut off chicken heads, burn yellow paper, and worship as brothers of the opposite sex.

As a loyal listener, Jiang Shuiyuan had the leisure to look around: "Teacher Ge, isn't it? I heard that Jingshi University has tens of thousands of acres of land, and it is completely a small city. ”

Ge Jun Tianshen didn't speak, but Chen Xuan relieved Jiang Shuiyuan's doubts: "You haven't been to Jingshi University before, right? According to the school's regulations, all vehicles except faculty and staff are prohibited from entering the campus, and we, as alumni, are no exception. As for the transportation problem on campus, don't worry, the school has considered it for decades, and there is a very convenient bus system inside. Like you said, this is a small city, not to mention that if we go to Jingshi University, why should we also see the main entrance of the school?"

Huang Tongyuan also said: "Yes, if you don't take a photo at the gate, it's like never coming!"

Ge Juntian finally stopped pretending to be forked: "Speaking of the gate of Jingshi University, there is a very famous story circulating!"
