Chapter 72: Hitting the wall

"What were you talking about just now? What happened to Brother Yuan's thesis?" Liu Yang was also attracted by what Li Zhenya and Wang Haitao said at this time. He stopped writing temporarily and asked with some confusion.

Xu Yuan didn't expect that the matter would spread so quickly. Even Li Zhenya and the others knew about it in the evening.

After all, there are no smartphones now, and the only way to get information from the Internet is to rely on computers, which means that many people in school are discussing this issue.

Of course, he would not keep his roommates' questions in suspense.

He folded a corner of the page of the textbook he was reading, turned around and answered the few people.

"The Annals of Mathematics did include my paper, and the school library should have the corresponding journal by then."

"This is true, it's amazing." Li Zhenya was the first to shout when he heard Xu Yuan admit it himself.

In addition to excitement, there was also pride on his face.

After all, he is the head of the dormitory. It would be an honor for him as the head of the dormitory to tell others that his roommate is so outstanding.

Maybe it would be easier to get to know the senior.

Wang Haitao didn't think as far as Li Zhenya. He directly grabbed Xu Yuan's right hand as if he was admiring a treasure, which made people feel goose bumps all over their body.

"It was this hand that wrote the paper that was accepted by the Annals of Mathematics. I must touch it carefully to avoid failing the midterm exam."

Xu Yuan couldn't stand Wang Haitao's greasy hand, and he quickly pulled his hand out and said speechlessly: "I typed the paper with both hands, and you will definitely fail the course if you don't review." It can be said that he was worried about Li Zhenya and Wang Haitao.

"Why do you have to tell me the source, brother? Can't you let me indulge in my fantasy for a little longer?"

Wang Haitao's expression suddenly turned into a bitter one, and even his tone sounded a little resentful when he said this.

For ordinary college students, the most frustrating time is when the exam is approaching. Either they cram for the exam or wait for the make-up exam later.

Xu Yuan knew Wang Haitao's study status very well, a typical case of being too repressed in high school and too indulgent in college.

In order to prevent the other party from crying and screaming after failing the course, and to create a quiet atmosphere in the dormitory and the neighboring dormitory, he felt it necessary to put some pressure on him.

“Have you read the mathematical analysis?”

"I guess we didn't do five high-level algebra questions today."

"Have you reviewed spatial analytic geometry?"

After a series of soul-torturing questions, Wang Haitao no longer had the relaxed feeling he had just now. He quickly raised his hands in surrender and returned to his seat to take out a book of mathematical analysis exercises by Jimmy Dovich.

"Stop talking, Yuan-ge. Can't I just review now?"

At this time, Li Zhenya next to him proudly added: "Fortunately, I have reviewed all of these."

Wang Haitao had just opened the exercise book when he heard this and turned around and asked in great surprise.

"Old Li."

"You've already finished your review, why did you drag me along to the playground to meet a senior?"

I was so angry that I didn't even call him the dormitory leader.

Li Zhenya replied confidently: "It is precisely because I have finished my review that I went to the playground."

After hearing this, Wang Haitao was suddenly speechless. It turned out that he was the only one who had not reviewed.

That's fine.

Xu Yuan didn't know whether to laugh or cry while listening to the conversation between the two. It could be said that they usually contributed 90% of the laughs in the dormitory.

He can definitely be called a living treasure.

Just when Xu Yuan thought the matter was over and was about to continue studying the textbook in his hand, he saw Liu Yang standing up and walking towards him.

"I remember that Yuan Ge wrote a paper during the military training period. I wonder what kind of content can be included in the Annals of Mathematics?"

Liu Yang was already surprised that Xu Yuan wrote a paper during military training, but he did not expect that the paper would be directly published in the Annals of Mathematics. He saw that the gap between him and Xu Yuan in mathematics was getting bigger and bigger.

Faced with Liu Yang's curiosity, Xu Yuan chose to satisfy him and turned around to explain it in detail.

“It’s about an interval problem in Carmichael numbers, and I proved it using a completely new sieve method.”

"But I am also standing on the shoulders of other mathematicians. Otherwise, I would not be able to solve this problem by myself."

It is worth mentioning that in the last sentence Xu Yuan was still humble and did not take all the credit on himself.

I was thinking about not giving Liu Yang too much of a blow all at once. It would be unfair if he gave up his major in mathematics like Lin Haoming did.

Besides, what he said was indeed correct.

Whether it was the proof of the infinite Carmichael number problem by Pomerance and other three mathematicians, or the improvement of Mr. Chen Jingrun's weighted sieve method, it was equivalent to standing on the shoulders of giants.

Otherwise, without these, he would not have been able to prove the remaining interval problem so easily.

Liu Yang's persistence in mathematics is obviously far greater than Lin Haoming's. After listening to Xu Yuan's explanation, he was happy for him.

In addition, he finally understood why Xu Yuan wrote this paper. After all, at the mathematics winter camp report meeting, he clearly remembered that the question Xu Yuan asked Professor Tang Shihong was about Carmichael numbers.

"Congratulations, Brother Yuan."

"It is a great achievement to be able to successfully prove the interval problem in Carmichael numbers."

As he put on a smile and congratulated Xu Yuan, Liu Yang sighed again as if he was thinking of something.

"If this is the case, I'm afraid Brother Yuan will have to graduate early, and it will be much more difficult to see each other again then." This sentence also resonated with Li Zhenya and Wang Haitao, making the atmosphere in the dormitory suddenly solemn.

Under normal circumstances, they could have been together for four years, but now Xu Yuan was so far ahead in mathematics that they would naturally fall behind if they couldn't keep up, and they wouldn't even be able to see his back.

Xu Yuan sensed everyone's sadness, and immediately said with a smile: "Who says we won't see each other anymore after we graduate from undergraduate school? You can still live here even if you become a master's or doctoral student, so we still have a long time to spend together." This livened up the atmosphere in the dormitory.

-

at the same time.

Lin Haoming, who was far away in the provincial capital Luyang, was a day student and he turned on the computer skillfully as soon as he returned home from school.

Although he has been admitted to the Computer Science Department of Yenching University and has no plans to continue participating in the competition this year, he still goes to school and attends classes as usual.

The main thing is that if you become decadent for a long time, you will probably be ruined.

You need to keep yourself in a state of learning every day.

In addition to reviewing high school knowledge, he also learns computer-related content in advance.

Sitting in front of the computer, I opened Tianya Community as usual, intending to study the technical posts in the computer section, when I was suddenly attracted by a very popular post.

“Does Qinghua’s new student’s solution to the Carmichael number spacing problem mark the rise of theoretical mathematics in my country?”

"The Carmichael number..."

"Qinghua is a new student."

After reading the title of the post, Lin Haoming repeated the key words in his mouth, and he always felt a sense of familiarity.

So without thinking, I clicked in to check it out.

It was not until he saw the two familiar words "Xu Yuan" mentioned in the content that his pupils suddenly shrank with excitement.

"It's really Yuan. He solved the Carmichael number problem and published his paper in the Annals of Mathematics."

"I knew that even when he went to college, Brother Yuan would still surprise people."

He was so excited that even the words he shouted became incoherent.

Fortunately, his parents are not living with him for the time being, otherwise they would have been woken up and rushed out of the room to scold him.

This joy lasted for more than ten minutes, until he finished reading the replies to the post one by one, and then he leaned back in his chair with satisfaction.

Tianya Community's user group is mostly industry elites, and they all spoke highly of this matter. Some practitioners in the field of mathematics even went to the official website of the Annals of Mathematics to read the paper carefully.

This has led to a much higher level of opinion about the level of Qinghua's Department of Mathematics, allowing everyone to discover the strength of the country's young mathematical talent.

Perhaps in the future it will be possible to drive the progress of domestic mathematics and produce academic results that will leave the international mathematics community speechless.

But soon Lin Haoming remembered a person in the community. At the beginning, this person accused Xu Yuan of graduating from a county high school. After being slapped in the face, he insisted that Xu Yuan's road to genius had come to an end and it was even impossible for him to achieve any academic results in the field of mathematics.

Now that Xu Yuan's paper has been published in the Annals of Mathematics, proving himself once again, he cannot let the other party off easily.

Although several months had passed and everyone in the forum had forgotten about the incident, and even Mr. Wu had not provoked a new dispute, it did not stop him from opening a new thread and making a big fuss.

When it comes to protecting Xu Yuan, Lin Haoming's execution ability is quite strong. He edited the post of criticism and published it in just a few minutes.

Many friends had witnessed the debate on that matter in the forum before, and they were excited at the time, so when they suddenly saw a post to criticize it, they naturally attacked without saying a word.

Many people called on Mr. Wu to make a public apology as he had said before.

"You said it was impossible for someone to achieve academic success. How can you explain it now?"

"Come out and apologize now."

"I didn't expect this to have a follow-up. I'm afraid the other party would never have thought that I'm a math genius."

"I guess this guy doesn't even know what a Carmichael number is."

"We Qinghua students cannot be slandered by anyone. Are you bullying us for not going online?"

……

Wu Yongren has been in Tianya community for so long, he must have added some friends' Penguin accounts. When he was reminded to post an apology in the Guantian Teahouse section, he expressed some confusion.

I took some time to log onto the forum and saw the criticism post, and my face immediately turned livid.

"The quality of users in the forum is really getting lower and lower. They even dare to brag about anything."

"So what if they are students from Qinghua University?"

"The paper was even published in the Annals of Mathematics. Do you really think I don't understand?"

He immediately put his hands on the keyboard and replied to the post while complaining unhappily.

I just trusted my own judgment without doing any verification on what was said in the post.

But you have to know that there are many young people among the active friends at this time, including graduate students and even teachers. When they see someone dare to question their own students with their eyes closed, they will definitely go all out and show off their talents.

It didn't even take long before a big shot uncovered Wu Yongren's true identity based on his past remarks and skills.

As the situation gradually got out of control, Wu Yongren suddenly realized that he seemed to have hit a brick wall this time.
