From all-round academic master to chief scientist

The closing ceremony is over and everything has settled.

The six players participating in the IMO are Lin Xiao, Ouyang Sheng, Sun Yu, Li Boyuan, Hu Chao, and Zou Ziyi. These six players will go to Romania, Cluj-Napoca before July 3 to participate in the 59th International Mathematical Olympiad.

As a national team that wants to represent the country in international competitions, the Hua Mathematics Association naturally needs to train them. The training period is divided into two phases, a total of 45 days, from April 16 to May 15, and June From the 16th to June 30th, and then take a flight to Romania on July 1st. The training location is in Shangjing, the Institute of Mathematics, Chinese Academy of Sciences.

Lin Xiao was really not interested in these trainings. It was tiring to go back and forth so many times, but there was no other way. People insisted that he participate, so he had no choice but to go.

Finally, the training time did not take up his time for the college entrance examination, otherwise the one million yuan from Beijing University would have been lost.

Time passed quickly, and Lin Xiao returned home for two weeks. During this period, the Qin Provincial Mathematical Society also awarded him and Sun Yu a scholarship of 20,000 yuan each, which directly expanded Lin Xiao's wallet a lot.

After that, on April 15, he took a train to Beijing and reported to the Institute of Mathematics, Chinese Academy of Sciences.

…

Reporting office.

"Are you that Lin Xiao?"

"Yes."

The teacher in charge of reception glanced at Lin Xiao and said with a smile: "Finally you are here. Many teachers want to see you."

"Ah this..." Lin Xiao touched his face: "Am I that attractive?"

The receptionist laughed and said, "Of course, you are so attractive and your grades are so good, what teacher wouldn't want to see you?"

"All right."

Lin Xiao sighed. Is it really all because of his talent?

Is his appearance really not noteworthy?

The receptionist saw him sigh and couldn't help but feel confused, but he didn't say anything and said: "You have been living in our dormitory this month. This is your key. It is a double room. You live with another player. , let’s take a look, it’s Sun Yu, you seem to be from the same province.”

"Is it Sun Yu? Is he here?"

"That's not the case yet." The receptionist said, "Okay, I'll take you to your dormitory now."

"Thank you, teacher. I'm sorry to trouble you."

Lin Xiao thanked him, then took his luggage and headed to the dormitory building with his teacher.

Although it is said to be a dormitory building, it is not a tube building like a school dormitory, but a building similar to a residential building. It has an elevator and is quite comfortable in decoration.

After all, this is a dormitory building prepared for researchers from the Chinese Academy of Sciences. If the conditions are poor, it would be really unjustifiable.

As for Lin Xiao's dormitory, it is on the second floor. It has two bedrooms and one living room. The two bedrooms are relatively spacious with beds, and there is also a desk for them to study.

After the receptionist helped Lin Xiao put away her luggage, she took out a three-piece bed set from the closet next to her. The bed was a 1.2-meter single bed and the mattress was already there, so she could just put the sheets on it. Fell asleep.

"Okay, the schedule has been sent to your group. Just look at the schedule and don't forget to attend the meeting tomorrow morning." The receptionist said, and then handed over a bunch of keys and a The card was placed on the bed, "Here are your keys, and your meal card. The meal card will be replenished to 300 yuan every day, which can be used to spend money with us. If you eat out, please ask for the receipt." Yes, I will reimburse you later."

"Okay." Lin Xiao responded. All the expenses for their coming here were provided by the Huaguo Mathematics Society. They didn't have to spend a penny on food, housing and transportation. Of course, as long as they didn't spend hundreds or even thousands of dollars a meal. kind.

Then the receptionist left here.

After seeing the teacher leave, Lin Xiao lay directly on the bed. The cold new sheets were a bit uncomfortable to sleep on.

After a while, he sat up again and looked out the window.

This is Guanzhong Village. Going to the Third Ring Road in Beijing is equivalent to saying that you have a suite in the Third Ring Road?

But soon he patted his head. Why did he have a suite? It was just a temporary stay for a month.

He got up and walked around the room again. The room was about 60 square meters. It was obviously very big for a dormitory. It also had an independent bathroom, a balcony and a washing machine. It was pretty good. At least I didn't have to worry about it for a month. Life.

After a brief look, Lin Xiao returned to his room, took out the book on partial differential equations and started reading.

This book was the last undergraduate mathematics textbook he read.

If you want to continue to study in depth after that, you will enter the content that graduate students need to learn. This aspect has more subdivided content and is also more difficult. Just mention a few, such as second-order elliptic equations, Lie groups and Lie algebra. , Riemann surface theory and so on.

Shangjing did not prepare any textbooks for Lin Xiao in these areas. After all, they never thought that Lin Xiao would be able to complete all undergraduate mathematics courses on his own before entering university.

Probably no one would believe that Lin Xiao could learn so quickly.

Moreover, he not only learns quickly, but also has a very solid memory of knowledge points. Basically, as long as he studies seriously, it will be difficult for him to forget the knowledge, which is also due to the help of the system.

In this way, after Lin Xiao studied for a few more hours, he felt a little hungry, so he automatically left the immersion state.

As long as he is not thinking about the problem, the feeling of hunger can still wake him up. If he is thinking about the problem like last time, he will probably be hungry for half a day without exiting the immersive state.

He ate when he was hungry, so Lin Xiao left his room. At this time, he was surprised to find that Sun Yu had already arrived and was leaning on the sofa in the living room, playing with his mobile phone.

"Hey, Lao Sun, when did you come?"

Sun Yu looked at him with the same confusion: "Why are you in the room?"

The two of them replied in unison: "I've been there a long time ago."

"..."

After a moment of silence, Lin Xiao touched her nose: "I've been here since the morning and have been studying in the room."

"Okay, I got here an hour ago."

Sun Yu said helplessly. He was startled when he heard the sound of opening the door just now. He almost didn't realize that there was a murderer hiding in the room and he wanted to come out and kill him.

However, Lin Xiao actually arrived this morning and studied in the room for so long in the afternoon. Sun Yu still has to admire this kind of hard work.

"Want to eat together? I don't know if the canteen of the Chinese Academy of Sciences is delicious or not."

"Okay, I happen to be hungry too."

With that said, the two left the dormitory together.
