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

Chapter 335 Why Does It Need to Be So Complicated?
"The world's top young mathematician, Hoho, has redefined the concept of young mathematicians! Omo, God Xu, the dream lover of 900 million girls. A mathematician with full sexual tension. A nobleman from the East, oh~"

"Brother, if you continue to yell here, I will kick you out and do it myself."

Xu Qingshan gritted his teeth and threatened Liu Ruchuan, who was holding a computer in his hands.

"Hey, don't be like that, Qingshan. I'm just repeating what people on the Internet say about you. Look at these photos of yours, you don't even know when you took them, right?"

Liu Ruochuan held the computer in front of Xu Qingshan and said happily.

Xue Xueqing and Wang Wei, who were sitting at their workstations nearby, did not dare to laugh openly. They could only appear to be concentrating on their work, but in fact their souls were elsewhere.

Xu Qingshan waved his hands in annoyance.

This senior brother of mine is good in every way except that he talks too much. He likes to say funny things, and he has some of the language talent of people from Tianjin.

"Okay, don't be so depressed, let's talk about ideas?"

Liu Ruochuan turned the chair over and rode on it like he was riding a horse. It was fun, but it did not look very elegant to sit like that in a suit.

"Let's discuss this later when Xiaoxi comes over. I want her to participate as well."

Xu Qingshan didn't bother to be polite with Liu Ruchuan and directly put forward his request.

"Your little girlfriend, sure."

Liu Ruochuan didn't care much. He also knew that Xu Qingshan's girlfriend assisted him in completing the twin prime conjecture. Even if Xu Qingshan sent someone over, he would at most be a second or third contributor, which was not a big deal for him.

"Do you want to let her come directly to my project? If you haven't obtained the qualifications yet, I will take care of her?"

Liu Ruochuan was smiling playfully. He signed the talent introduction agreement earlier than Xu Qingshan, and now the school has started to arrange an office for him.

But unlike Xu Qingshan, he is not in the scientific research system of the Institute of Mathematics, but in the teaching and research system. He needs to take an algebraic geometry course in the School of Mathematics.

"You are not needed. It's too early for her. I will be able to take care of her by then."

Xu Qingshan rolled his eyes at Liu Ruchuan and continued to look at the document in his hand.

"Knock knock!"

There was a gentle knock on the office door.

Everyone looked up and saw that it was Jiang Huanxi carrying a bag.

When she saw a stranger in the room, she became much more polite.

If only Xiao Xue, Xiao Wang and others were in the room, Jiang Huanxi would be more natural.

"Oh, our junior sister is here. What's up? Is she doing so badly in your Qingshan? Do you have to knock on the door when you come to the office? Shouldn't you have to knock at home?"

Liu Ruochuan joked with a giggle.

Jiang Huanxi's face turned slightly red after hearing the words of this unfamiliar senior, and she hurriedly explained in a somewhat shy manner.

"That's not the case. I didn't expect a senior to come today, and I was afraid to disturb you."

"I see. You think I'm in the way."

"No, no, that's me."

Jiang Huanxi looked at Xu Qingshan, and Xu Qingshan reached out and patted Liu Ruochuan on the shoulder and said.

"Stop teasing her. Xiaoxi, come here and sit inside. Xiaoxue and Xiaowang, you can also come and listen. We will be moving offices next month. Cherish this time now."

Xu Qingshan stood up and moved a chair for Jiang Huanxi.

Jiang Huanxi squeezed her little body and moved directly to the wall next to Xu Qingshan's desk and sat next to him.

Liu Ruochuan sat at the side of the table, and Xue Xueqing and Wang Wei also sat side by side.

"Okay, everyone, come and take a look. I think you have all read p-adic Hodge theory a little bit in advance. It is a tool for studying geometric objects by digitizing them through linear algebra. It is mainly aimed at geometric objects on p-adic domains, and its core is how to understand and classify p-adic Galois representations."

"Yes, I have. You can get information by comparing different types of cohomology. The ones I saw yesterday were etale cohomology and de Rham cohomology."

Xue Xueqing was quite enthusiastic and interested in exploring new fields. As soon as Xu Qingshan finished speaking, she raised her hand and spoke.

"Jean-Pierre Serre's Local Fields discusses algebraic theory on local fields. I've read the first two parts and I feel that Logarithmic Algebraic Geometry is very important when doing various comparison theorems in p-adic Hodge. You can take a look at that paper."

After Xu Qingshan gave them an idea, he let the three girls discuss and exchange ideas on their own about the content that they had been asked to study in advance. Liu Ruchuan took the idea document that Xu Qingshan handed over and began to look through it.

It's quite lively in the small office.

Several people gathered here and had a heated discussion. With the guidance of Liu Ruochuan, a world-class p-advanced Hodge theory scholar who had just returned from further studies in France, and Xu Qingshan, a world-renowned top scholar in the field of number theory, the three girls' insights in this field improved rapidly over time.

This atmosphere is great.

However, this kind of atmosphere of discussion and learning is often only found in the research laboratories of young tutors.

If you meet a big boss with great authority, and you cannot learn enough, he will not give you the opportunity to learn while chatting in the group meeting.

The sun rises and sets in the sky, and the clock hands tick away.

“Ah, it feels so good!”

"Well, I feel much better."

Xue Xueqing stretched and looked out the window. She was sitting facing the window and it was already late.

Wang Wei pushed his glasses, but kept his head down, staring at the notes in his hands in deep thought, and answered casually.

"Junior brother, your two students are quite interesting. Are they comfortable studying and working?"

Liu Ruochuan took a sip of water with a bitter face.

He had been wandering around outside for so long, especially in such a romantic, passionate and freedom-loving country like France, but this was the first time he felt drained by his students.

have to say.

Liu Ruochuan previously thought that among Xu Qingshan’s achievements, the work of these two students and Jiang Huanxi was just nominal and had limited impact.

After all, Xu Qingshan's halo is too great.

But today, with this half-communication, half-teaching rhythm, Liu Ruochuan felt the learning and thinking abilities of these students.

"Brother, are you feeling unwell?"

Xu Qingshan put away the documents in front of him, looked at Liu Ruchuan's bitter face, and then he smiled.

"We often do this, brainstorming, and everyone enjoys it. Today is your first time here, and I'm worried that you won't be able to adapt, so I'm going to stop. If you can adapt, we can have supper together next time, okay?"

Xu Qingshan looked at Liu Ruochuan, and the more bitter Liu Ruochuan's expression became, the happier he became.

"Forget it, I have to study hard and clean up my new office. You should discuss it among yourselves. They have already learned my basics, so there is nothing more to learn."

Liu Ruochuan fled in panic.

Originally he was having a great time in Xu Qingshan's office, but now he couldn't wait to escape from this devil's den.

"Haha, Senior Brother Liu is quite interesting."

Jiang Huanxi looked at Xu Qingshan. After the discussion, she felt familiar with the situation and was no longer so restrained.

"It's interesting, but it looks like his teaching days will not be easy in the future."

Xu Qingshan smiled and waved his hand, asking Xiao Xue and Xiao Wang to pack up and go back to rest early, while he himself would accompany Jiang Huanxi to have a meal and take a walk.

Now it is almost spring and the water is gurgling.

It's a good time to take a walk.

Although the weather is still a little cold, I can already wear a single piece of clothing and a vest and walk around.

"Are you going to pick up Tong Tong tonight?" The two turned off the lights, went downstairs, and walked out of the small building of the Mathematical Research Institute.

Jiang Huanxi took the initiative to ask Xu Qingshan.

"Probably not tonight. She just sent a message saying she's still in the lab and can't leave because she has to monitor the experiment today. Just let us eat by ourselves."

Xu Qingshan glanced at his phone and found that Tong Tong had not sent any more messages.

"Ah? Did she send a message?"

Jiang Huanxi rummaged through her bag for a while, took out her cell phone and looked at it, and indeed found the message from Tong Tong.

"You two are so good now?"

Xu Qingshan was in a good mood and made a joke.

"What? Do you still hope that our relationship will be bad?"

Jiang Huanxi squinted her deer eyes, curled her lips, and glanced at Xu Qingshan.

"No, I'm just curious."

A smile never disappears, it just moves.

Liu Ruochuan's playful smile had now shifted to Xu Qingshan's face.

"Humph."

Jiang Huanxi gently kicked Xu Qingshan's calf, and his short legs moved forward.

"She told us to leave her alone, but we can't really leave her alone. Let's go to the cafeteria and eat the braised chicken with rice. After that, bring her a Northeastern rice dumpling. She seems to like that a lot these days."

Jiang Huanxi muttered to herself, and she seemed to be more worried and concerned about Tong Tong than Xu Qingshan.

Xu Qingshan didn't dare to say anything else. He touched his head and quickly followed.

The two of them had a simple meal of braised chicken with rice. Xu Qingshan wanted to eat it slowly, but Jiang Huanxi dragged him to buy a lunch pack and went straight to the laboratory of the School of Chemistry.

It’s just that they don’t go to the Chemistry College often, so they are not very clear about its geographical location.

Moreover, at this time, the lights in the Chemistry School laboratory were still on.

The diligence of Peking University students is still there.

Xu Qingshan wanted to call Tong Tong, but was stopped by Jiang Huanxi.

"She's still doing experiments now, so she may not be able to take the call. Let's take a look and visit the laboratory of the School of Chemistry."

Xu Qingshan also knew Jiang Huanxi's plan.

My wife likes it, so what can I do? I can only accompany her shopping.

Perhaps this is the difference between academic couples.

Others like to go window shopping, while academic couples like to visit experimental bases and observe various academic fields.

However, when they were halfway through their visit, they saw Tong Tong wearing a white coat through the window.

"Hey, Tong Tong is there."

Jiang Huanxi pointed at Tong Tong, who was staring at the experimental data instrument in the laboratory with his hands in his pockets.

Tong Tong was seen wearing a white coat, a mask on his face, goggles, his hair was tied up and he was wearing a blue protective cap.

Fully armed and with a strong sense of safety.

“It does seem to be the case.”

Xu Qingshan also nodded in praise.

"Let's go in and take a look."

Tong Tong was the only one in the laboratory, no one else. Xu Qingshan and the others had no scruples and went into the lounge and put on a white coat. This was a public laboratory and it was relatively free, so they left their lunch bags in the lounge.

"Huh? Why are you here?"

Tong Tong heard the noise of the door opening and looked up warily, but saw Xu Qingshan and Jiang Huanxi who were wearing clothes but not masks. The vigilance in his eyes disappeared and he asked.

"Isn't this your sister Xiaoxi who was worried that you didn't have dinner, so she brought you a lunch bag? She left it in the lounge. I'll help keep an eye on it for you. Come and eat."

Xu Qingshan smiled warmly and moved closer to Tong Tong to take a look.

"Are you doing inorganic ion identification and glass refractive index measurement?"

"Well, we have to wait anyway, and it just so happens that we have everything here, so we can do both."

Tong Tong did not leave, but looked at Jiang Huanxi, with a hint of warmth in his eyes.

After spending a long time with Jiang Huanxi, she actually gradually understood why Xu Qingshan liked Jiang Huanxi.

Not to mention Xu Qingshan, she felt that from a friend's perspective, she was also slowly falling in love with Jiang Huanxi.

"What are you waiting for?"

Xu Qingshan asked curiously.

"I'm thinking about how to design a method that can avoid the production of toxic gases. The first step of this question requires that methyl salicylate be hydrolyzed with sodium hydroxide, and then HCl is added to pH = 2 to precipitate it. I've just started doing it, but I don't know if there are other ingredients in the sample given besides methyl salicylate. Will there be side effects from excessive acid? Will more impurities appear?"

"Why do you think so much?"

Xu Qingshan rubbed Tong Tong's little hat.

"You're already on the national team, why are you still hesitating on such a simple question? You're just practicing now. No matter what, finish it first. Don't think about anything else. Just finish whatever you want to do."

As Xu Qingshan spoke, Tong Tong seemed somewhat unconvinced.

"I simulate every practice session according to the competition situation. If we want to win the gold medal, we must avoid mistakes as much as possible. There can't be even the slightest problem."

Tong Tong had a stubborn look on her face. She had her own ideas.
"Don't put so much pressure on yourself. Whether it's a gold medal or a silver medal, you are the best."

Xu Qingshan said.

"I want a gold medal! Without a gold medal, you will fail in the competition!"

Tong Tong was a little stressed. After hearing Xu Qingshan's words, he retorted in a low but somewhat abrupt voice.

"Okay, okay, Gold Medal, you can do it, but you still have to go eat first. I'll help you look at the data. You have to practice, but you still have to eat well. After eating, you can do it longer."

Xu Qingshan keenly sensed Tong Tong's desire to win and did not continue to persuade Tong Tong.

"Sorry bro, I am."

"It's ok."

Xu Qingshan rubbed Tong Tong's head again.

"I just hope you can do everything happily."

"Little boy, let's go and have some lunch."

Jiang Huanxi took Tong Tong's arm and took her to the lounge to eat.

Xu Qingshan was very quick and efficient, and he finished the instrument and titration operations on the table in no time.

Only then did he record the data, pack up his things, and walk out of the laboratory.
