Just turned over a new leaf and became a wise and intelligent student

Chapter 342: The Origin of Mathematics

Although Xu Qingshan is willful, he has the capital to be willful.

That afternoon, there were some changes on the official website of the Peking University Mathematics and Applied Laboratory regarding the research direction that Xu Qingshan was in charge of, and Liu Ruochuan's name was also entered after it, alongside Zhu Xiaohua and others.

Compared with other research directions and research groups, the two helmsmen of Xu's group are really too young. Even Liu Ruochuan is younger than some senior postdoctoral fellows in other groups.

But no one dared to underestimate this group.

After Xu Qingshan came out of Tian Gang's office, he went directly to Huaqing. Qiu Yong came back from Liangxi and sent him a message asking him to come over.

The distance between Peking University and Huaqing University is too close.

Xu Qingshan often went to Huaqing and was familiar with the small paths.

Xu Qingshan came out of the east gate of Peking University, crossed the road, and quickly entered from the southwest gate of Huaqing University. He followed the road and passed by the entrance of Huaqing Primary School, and went all the way to the Energy Science Building.

Across the aisle from the Energy Science Building are the Science and Technology Building and the Information Science Building. Many young students were walking towards us. Each of them was wearing glasses and had a sloppy mustache. It was obvious at first glance that each of them was a natural science genius.

But when they were walking, some people were holding books in their hands, some were chatting about the topic they had just discussed, and not many people noticed Xu Qingshan.

Even if she saw Xu Qingshan, she would only subconsciously think that this guy was really handsome, and then continue to think about her own problems.

Very normal.

You know, at Peking University, ever since Xu Qingshan’s news broadcast fever passed, although many people recognized him on the street, most people just looked at him a few more times and were unable to determine who he was.

Maybe when you see him, you will just feel that this handsome guy looks familiar, but you don’t know why. Many people will fill in the blank in their minds and think that it may be because the other person has outstanding looks, so when they meet him outside, they take a few more glances and remember him.

If you don't believe it, even if you let Yang Zhenning, Li Zhengdao and others come back now and take a walk around the campuses of Peking University and Huaqing University, you will see how many people can recognize them by their faces.

Even when celebrities who occupy media resources every day are dressed casually, passers-by may not be sure that these are the big stars they see on TV every day.

Just when Xu Qingshan was quietly lamenting that his popularity was dropping so quickly, he was about to turn the corner and walk into the building, but was stopped by a boy.

Looking at the young man with a long face, narrow cheeks and protruding ears in front of him, Xu Qingshan was sure that he didn't know him. But the other party stood in front of him and just smiled brightly, as brightly as a little monkey, without saying anything. So he could only stop and asked with some confusion.

"Hello?"

“Hello! God Xu, my name is Hou Yong, you are God Xu, right?!”

The young man looked very excited, and Xu Qingshan smiled and nodded.

"If you're looking for Xu Qingshan, then it should be me."

"God Xu, can you sign for me? Here, here, the pen is here, just sign on my clothes!"

Hou Yong's name is very popular, but his face is not. He is also a bit of a social bull. He took out a marker from his bag and pulled his collar to get Xu Qingshan's autograph.

Xu Qingshan simply signed an artistic signature and asked casually.

"What do you study?"

"Computer Science, I just entered the Yao Class this year! Master Xu, they all say you are great at math, but I am different! I fell in love with you after watching your ICML video! They don't understand at all, your vision and insights are simply overwhelming."

The young man was indeed very excited. After Xu Qingshan signed his autograph, he actually stopped looking at Xu Qingshan and instead looked at the autograph over and over again. He almost took off his clothes on the spot.

"That's really exaggerated. If you have the chance, come to Beijing University to visit me. If you are interested in graduate school, you can also study under me. I'm going in first."

Xu Qingshan was somewhat overwhelmed by this primate enthusiasm, so he smiled and waved his hand before going into the building.

"Okay! Okay!"

Hou Yong looked at Xu Qingshan's back with shining eyes, and then looked at the signature on his chest.

"No, I have to show off to Xiaoyang when I get back. When he comes to Yaoban to be my junior at the end of the year, I will take him to see Master Xu. What math? Master Xu is our computer scientist!"

Hou Yong opened his coat, showing Xu Qingshan's signature, and walked with a breeze.

Xu Qingshan found Qiu Yong, who was looking at a material analysis report. When he saw Xu Qingshan come in, he put down the report, stood up, pulled a chair, and smiled bitterly.

"Qingshan, how come you guys at Jingda are so quick? My boss has been calling me every day lately, and he almost went to Liangxi to arrest me and hold me accountable."

Qiu Yong had always been eyeing Xu Qingshan, but during the honeymoon period of the cooperation, Xu Qingshan was signed by Peking University first.

"I didn't expect Dean Tian and Dean Xu to bring up this matter as soon as I came back. Beijing University has always provided a lot of resources. We can't be ungrateful, right?"

Xu Qingshan smiled and Qiu Yong had nothing to say.

"Okay, but we can't give up on the cooperation. It's still Shangde's business to find you this time, but it's good news."

Qiu Yong smiled bitterly and continued.

"With the mayors of both sides checking, the efficiency is amazingly high. Liangxi Suntech has been completely split up. As for the overseas subsidiaries, they have been reported back to the State-owned Assets Supervision and Administration Commission and are considered to be nationalized. We don't need to worry about them. The domestic real industry sector has retained the Liangxi Suntech entity and is still called Liangxi Suntech Solar Energy. The debt repayment has been completed. Ludao still has a lot of cash. The sector you want has been established in the Xiang'an area of ​​Ludao. The ownership of the production line has been changed. Several fleets of vehicles were delivered overnight. The factory has begun to be built, and the relevant technologies are also going through the transfer procedures. The new company is called Xinneng'an. Are you relieved now?"

Xu Qingshan nodded. It was he who decided on the name Xin Neng'an.

"Your Mayor Liu is also a smart man. Old Zhu didn't get much benefit from him."

Qiu Yong said this half-jokingly.

"But at least Mayor Zhu has completely eliminated this big risk, right? Mayor Liu's term in office is not long after all. After doing this, he will either be promoted or demoted. He has finally put all his life's learning into practice."

Xu Qingshan also replied with a smile.

"These are the application materials for our visit this time, as well as the description of our research and cooperation. If you find no problems, I will submit them to the ministry to prevent anyone from making trouble with them later."

Qiu Yong handed the truly important and key document to Xu Qingshan. Xu Qingshan restrained his smile, went through the document carefully, and only signed his name on the back of the document after confirming that it was correct.

"By the way, how is your scientific computing software now? Last time, our lab checked the data set and sent it to you, why haven't you given me the next task yet?"

Qiu Yong put away the document, sealed it carefully, and asked again.

"I've been busy moving the lab recently. I plan to build a computer room for my lab, which will be more convenient. Once the hardware is ready, the server can be directly deployed and the product can be released. There is no other work required, so I will just wait for the finished product."

Xu Qingshan stood up.

"Is there anything else you want to tell me? If not, I'll leave first. I'm busy with a lot of things at school."

"Go ahead, go ahead. Even if I lock you up here, it's useless. You are in Cao's camp but your heart is with Han."

Qiu Yong pursed his lips and waved his hand.

"That's right. If you, Dean Qiu, give the order, shouldn't I come here in a hurry? Let's go. Bye."

Xu Qingshan waved and left in a cool manner, but Qiu Yong sighed secretly in the room.

When Xu Qingshan came out of Huaqing, it was already late. He called Wang Wei and told them not to wait for him in the new laboratory. He went straight back to Yandongyuan.

I almost forgot that the school was going to arrange a new teacher's apartment for me. I have lived in this small two-bedroom apartment for more than half a year and finally made it feel like home. Now I have to move in.

When I got home in the evening, Jiang Huanxi hadn't come back yet. She had a full day of classes and ate in the cafeteria. Tong Tong hadn't come back either. She was still doing experiments and it was normal for her not to come back for dinner in the evening.

No one is at home, I'm all alone.

Xu Qingshan had no interest in cooking, so he just made do with some bread and read the literature on Hodge theory.

After watching for a long time, Xu Qingshan's cell phone rang. It was Liu Ruchuan calling.

"Brother, what's wrong?"

"What are you doing? I just went to science class, and I seemed to see your girlfriend in class. She even said hello to me, but I'm a little face-blind, so I didn't recognize her."

As Liu Ruochuan spoke, Xu Qingshan was stunned for a moment.

"You've started teaching students so soon? These classes were suddenly inserted in the middle of the year?"

"No, I was just helping Senior Brother Xiaohua with a class. Your boyfriend was sitting alone in the first row, with several girls next to him. I'm shy and introverted, so I don't dare to talk to female students."

Liu Ruchuan kept spouting golden sentences, which also amused Xu Qingshan.

"Come on, get out of class is over now?"

"Yes, do you want to go get some midnight snack together? I'll treat you. It's late at night and classes are really tiring. I have something good for you. My luggage from France has finally been mailed back, and no one told me that international logistics would be so much slower than me carrying it in person."

Liu Ruochuan suggested, and Xu Qingshan looked at the plastic bag of bread he had thrown aside and agreed.

"Then I'll call Huanxi and Tongtong. I'll bring two people with me. Is that okay?"

"Yes, yes, yes, really, you want to show off your love and your sister, right? Just wait, when my French girlfriend comes to China to find me, I will show it to you in person."

Liu Ruochuan hesitated, but still agreed.

As he was speaking, the door outside Xu Qingshan's house opened. He stood up and took a look, and saw that it was Jiang Huanxi and Tong Tong who came back together.

"Okay, send me the location later. They are both back."

"What place? Go out of the East Gate and head to Wudaokou. There's a new Old Soldier BBQ restaurant there. I want to eat the roast suckling pig. You guys are just the right person to accompany me."

"Row."

After hanging up the phone, Xu Qingshan left the room. Jiang Huanxi and Tong Tong were putting the things in their hands against the wall and were about to take off their scarves and coats.

"Don't take them off. Keep them on. I guess you two didn't eat much tonight. Let's go. Someone's treating us. Let's go have a midnight snack."

Xu Qingshan picked up his clothes and put them on. Although it was only April, it was still a little cold in the capital.

"Who?"

Jiang Huanxi stopped.

"Brother Ruochuan, he has something to give me. I ate bread at night, so I can just give him a big meal."

After a few words, Xu Qingshan put on his clothes.

Tong Tong didn't say anything, but silently put the scarf back on. Her experiment today didn't go very smoothly, and she was still reviewing it in her mind. She also didn't have dinner, so she was thinking about coming back and cooking a bowl of instant noodles.

The three of them walked to the Veteran BBQ that Liu Ruchuan mentioned.

It was a roadside stall. In this weather, there was a simple shed specially built for it. Xu Qingshan looked around and saw Liu Ruchuan sitting alone at a long table, with his head hunched over and looking at his phone.

"Have you ordered yet?"

Xu Qingshan didn't hesitate to go into the room and took a tissue to wipe the chairs for Jiang Huanxi and the others. He then sat next to Liu Ruochuan, while Jiang Huanxi and Tong Tong sat on the other side.

Xu Qingshan and the others came to discuss something, and they came to have dinner.

"We ordered two small roast suckling pigs, one for the two of us and one for Xiao Jiang and Xiao Tong. This way it's more convenient. There are also some other barbecues and skewers. I ordered a little of each and put them in the middle. Just take whatever you like."

As Liu Ruochuan spoke, he picked up his bag from the ground beside him, half-unzipped it mysteriously, put his hand in, and raised his eyebrows at Xu Qingshan.

"Guess what I'm going to give you?"

"What can you give me? French specialties? Baguette?"

Xu Qingshan rubbed his hands and answered casually.

"Heh, heh, superficial!"

Liu Ruochuan smiled evilly and took his hand out of his bag. He actually took out a huge book.

A thick black book was placed out front, with a string of words on it that Xu Qingshan could hardly understand. Although they looked like letters, they were not English at all.

"Dang Dang!"

"The original French edition of Bourbaki's Elements of Mathematics, the first volume of the first edition! Do you like it?"

Liu Ruochuan raised his eyebrows wildly, seeming to be very satisfied with the gift he gave to Xu Qingshan.

Xu Qingshan looked confused.

"Bourbaki? Are you talking about the school formed by Didoni and Weir?"

"Yes, Nicolas Bourbaki, The Elements of Mathematics, haven't you heard of it?"

Liu Ruochuan looked incredulous.

Xu Qingshan shook his head.

"I've seen this mentioned somewhere before. I've never read this book. I don't understand French. And as for Principles of Mathematics, isn't there a book by Russell? I've read that one."

Liu Ruochuan said with a look of regret.

"Then you must read this. It would be a pity for a genius like you not to read Mathematics Elements. I guarantee that you can get some inspiration from this original book. I have absorbed a lot from it."

Xu Qingshan took the mathematics monograph which looked a little old but was extremely well preserved and in excellent condition, looked at it, and nodded.

"Then I might have to learn French first."

"That's not necessary. Learning French takes a lot of time. There's an English translation of this book. You can just keep the one I'm giving you. It seems to have reached 40 volumes now. This is the original manuscript of the first edition. In fact, there are quite a few problems. The latest edition has made a lot of revisions. It would be more useful to read that one."

Liu Ruochuan seemed to like this mathematical monograph very much and talked about it at length.

The roast suckling pig was served on the table. The two girls had eaten half of it. Liu Ruchuan was still holding the cut pork pieces in his hand and talking incessantly.

Xu Qingshan knew how to stuff the food into his mouth piece by piece.
