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

Chapter 284 Challenger and Guardian Knight
Xue Xueqing stood at the door with a pile of documents in her hands, staring in amazement at Xu Qingshan and Wang Wei who had made the entire room a mess.

"Xue Xue, you're here, come and help."

Wang Wei was in a panic.

Although Xu Qingshan doesn't need this information, she does!

This document is not good, she should also study why it is not good, right?

However, Wang Wei also admired Xu Qingshan's ability from the bottom of her heart. It was hard for her to imagine how Xu Qingshan could judge whether a document was useful by just glancing through it.

"What happened?"

Xiao Xue changed from his usual liveliness and hopping. He looked at Xu Qingshan's back and Wang Wei with a strange expression and asked in a low voice.

Mainly from the perspective of an observer, Xu Qingshan's current state was like that of a madman.

Someone would fiddle with the documents in his hand as if he was playing with them, fanning them with the pages, and then either throw them behind him or squat on the ground and fiddle with them.

The office is in a terrible mess.

It looked like he was having a mental breakdown.

"Hey, come over here and help clean up first. The teacher is in a very good mood now, don't interrupt him."

Wang Wei pulled Xue Xueqing and whispered a few words to her. Only then did Xue Xueqing follow her to pack up with half belief, half doubt and half worry.

I don’t know how long it took.

Xu Qingshan did not have many documents at hand. The ground was filled with various materials, and in the middle of the materials, there were lines, formulas and patterns drawn by Xu Qingshan with chalk.

Xu Qingshan stood by the table, admiring his masterpiece and thinking and analyzing it step by step.

His tall figure seemed even more upright at the table.

He looked quite noble as he stroked his chin in deep thought. Although his hair was a little messy due to not having been cut for a long time, and his tight clothes made his muscles vaguely visible due to sweat, his aura of being immersed in academics and knowledge was fascinating.

Xue Xueqing took out a small camera from her seat and subconsciously took a photo to record Xu Qingshan's wonderful moment.

She didn't know that the scene she was recording at this moment would be the beginning of a great journey.

But she understood very well.

If you follow such a mentor, you don’t need to worry about whether you can produce results.

She only needs to consider what kind of posture will produce what kind of results.

She turned her head and found that Wang Wei next to her was sorting out the manuscript that Xu Qingshan had just discarded, while taking notes casually. There was also a thick notebook next to him, which was covered with dense words.

This little girl is starting to overtake again.

Xue Xueqing felt a little ashamed for a moment that she had gone out to catch her breath these past two days and went to the newly opened KTV to sing with her old classmates.

Although a balance between work and rest is the hard truth.

But she is faced with a genius mentor who is almost the supreme and invincible among young people, as well as a fellow student who is secretly introverted, and a talented girl who is currently taking exams but whose level is actually rising rapidly under the guidance of her husband, the mentor.

Xue Xueqing only felt that she was under great pressure, and the last thought of relaxing was wiped out.

She didn't want to end up not being able to board the super ship of her mentor Xu Qingshan.

"Director, your email."

After Xu Qingshan turned around and breathed a sigh of relief, Xue Xueqing dared to step forward and hand him the mail she had just brought back from the message room downstairs.

"Oh? Who sent it?"

Xu Qingshan took the package and spoke to Wang Wei and Xue Xueqing.

"You two help me put the documents on the floor in order and clean the floor. I'll take a break."

Wang Wei nodded, and Xue Xueqing had already squatted over and started marking with a marker.

Two calves were there to clean up.

Xu Qingshan looked at the package himself.

ICML.

Haven't seen this name for a long time?
Xu Qingshan was in a daze for a moment. The recent work at the Information Technology Center did not require his help for the time being. Davis and the others had discussed coming over to make an appointment with him. After the Spring Festival next year, there would be a busy period, and they would be working non-stop.

This made Xu Qingshan almost forget that he was also a small expert in the field of machine learning.

If Xu Qingshan guessed correctly, the document that was mailed this time should be the conference proceedings of ICML.

Normally, the conference is held in the middle of the month, so the electronic proceedings of the ICML conference will be published in about 3-6 months and will be included in the EI index in about half a year.

The physical collection of papers that Xu Qingshan received was an exquisite collection version printed by the organizing committee at the time. It has no selling price and only pure collection value.

It is not available in every session. It mainly depends on the conscience and wallet of the organizing committee.

Xu Qingshan didn't take this matter too seriously.

He casually placed the sample magazine on the table, then sat down and turned the laptop around, leaving it for the two calves to clean up. He sat outside the desk and began to use the computer to search for more information he needed.

There are limits to finding a direction for a breakthrough in the Riemann hypothesis based on current data.

Many people have poured their academic enthusiasm into the Riemann hypothesis like moths to a flame, but they have never received a response from the God of Mathematics, and have never received that hand of God.

During this long journey, many solutions emerged that were considered brilliant at the time.

But in the end, they were all like geckos with their tails cut off, with no further developments.

After taking a comprehensive look at the overall situation, Xu Qingshan decided to give up further exploring these ideas.

Because he couldn't see more inspiration and thinking singularities at the end of his train of thought, he felt that many people had walked into a dead end along this path.

"teacher?"

Wang Wei and Xue Xueqing packed up and prepared to tell Xu Qingshan, but Xu Qingshan fell into his mysterious state again.

There was no other way, Xue Xueqing could only quietly use her cell phone to send a message to her master's wife.

After Jiang Huanxi finished the exam and came to the office with lunch, the two of them quietly left.

Xu Qingshan was completely unaware of what was happening in the outside world.

He was still conscious of the context he had sorted out today.

Up to now, thanks to computer-assisted calculations, more than 1 billion non-trivial zeros of the zeta function have been examined, and their real parts are indeed located on the line equal to 2/.

However, this cannot serve as valid evidence to prove the Riemann hypothesis.

The advancement of the Riemann hypothesis is not just about proving it.

A great mathematical problem. Since there are attackers, there are naturally defenders.

Just like the gambling king Bang that Xu Qingshan met in Princeton, he is the guardian knight of the Riemann hypothesis.

The duty of the Guardian Knight is to use all the knowledge he has learned to knock down with a super stick all those unscrupulous people who try to prove greatness in a false way.

In the world of mathematics.

Knowledge is the most powerful weapon, and the ability to master mathematical tools is the ability to wield weapons.

And every great proof is accompanied by a wonderful fight on both sides.

Sometimes, at mathematicians' conferences, academic debates break out that are as exciting as those in Ace Attorney.

Just like the solution mentioned above, even with the most powerful supercomputer, it can be verified to have more functions.

But mathematicians who claim to be Riemann's guardian knights only need to find a counterexample to successfully refute it. Therefore, mathematicians have been trying to prove that there are no other zero points outside the line where the real part is equal to 1/2.

But it's obvious.

This kind of contradiction of the unbounded definition is extremely difficult to achieve.

Then, some insightful mathematicians began to prove that outside the straight line where the real part is equal to 1/2, the non-trivial zeros of the zeta function are extremely rare - so rare that there are only N of them at most.

In this case of pre-defined boundaries and space.

When they were able to reduce N to 0, they proved the Riemann hypothesis.

Doesn’t it sound like there is no difference from the previous method?
Actually there are, but not many.

So this way of thinking cannot be solved.

When everyone was scratching their heads, a tough guy suddenly appeared. Albert Ingham established an upper bound on the number of non-trivial zeros whose real part is not equal to 1/2: he said that in the interval of real part [0.75, 1] ​​and imaginary part not exceeding y, there are at most y3/5+c zeros, where c is a constant between 0 and 9.

He proposed this conclusion in the 20s, and the upper bound validity of this conclusion lasted for more than 40 years.

Xu Qingshan felt that he had vaguely grasped some clues, but they were not very obvious.

"Qingshan?"

When Xu Qingshan began to come back to his senses, Jiang Huanxi, who was writing a paper and waiting quietly beside him, reacted first and called him softly.

"Hey, Xiaoxi, why are you here? What time is it now?"

Xu Qingshan rubbed his eyes in confusion. If he was in a daze for too long, mysterious secretions would appear in the corners of his eyes.

"It's past 8 o'clock. You were too excited today. Senior Sister Xue and Senior Sister Wang have already gone back. They left me a message and I knew you were here alone."

Jiang Huanxi reached out and took out the towel that had been soaked in the basin and warmed over and over again, wrung it out clean, and wiped Xu Qingshan's face herself.

"I can do it myself."

Although the two had a close relationship, Xu Qingshan was not the kind of young master who would have everything handed to him, so he was still a little uncomfortable being served like this.

"How are you feeling? Any progress?"

Jiang Huanxi asked softly.

"A little, but not much. I am now considering the feasibility of new ideas. But you..."

After washing his face several times, Xu Qingshan finally recovered. The CPU in his brain had cooled down and resumed normal operation.

At this time, he also noticed that Jiang Huanxi's mood seemed not quite right.

"What's wrong? Creek."

Xu Qingshan put down the towel, wiped his still wet hands on his body, gently rubbed Jiang Huanxi's little head, and asked.

But Jiang Huanxi, who was usually well-behaved, cute and obedient, subconsciously avoided Xu Qingshan's head rub today and looked at Xu Qingshan calmly.

"Are you unhappy because of my state today?"

Xu Qingshan realized that the problem was probably quite serious.

He immediately sat up straight and looked into Jiang Huanxi's eyes. He had done nothing wrong and was still very confident.

Jiang Huanxi shook her head and she also stared at Xu Qingshan boldly.

This was perhaps the most serious eye contact between the two of them since they were together.

Jiang Huanxi wanted to see clearly whether Xu Qingshan felt guilty.

Xu Qingshan wanted to know what Jiang Huanxi cared about.

"No, nothing happened. Tong Tong called you at night, and I saw that you were still in a state of panic, so I picked up the phone."

Jiang Huanxi said softly.

Hearing this, Xu Qingshan was stunned, but he did not feel guilty. Instead, he continued to look at Jiang Huanxi seriously.

He is very clear.

During a conversation on such crucial issues, if one's eyes wander, answers are inaccurate, or one speaks unclearly, it will be an absolute dead end!

Only by facing challenges head-on and confronting them boldly can we live against death and gain that glimmer of hope for survival.

What Xu Qingshan wanted to do was not in line with common sense.

For the first time, Jiang Huanxi continued to stare at Xu Qingshan without showing any weakness. The light in the office was not very bright.

The couple looked at each other like this, but there was no hint of ambiguity between them.

It was like a cold interrogation room.

Take a step forward, and if it is the right one, then when the warm spring comes, perhaps the feelings will be even stronger.

If you take a step back, the tower is wrong, and it will be like winter approaching, and every step will be like walking on thin ice.

Xu Qingshan's heart was pounding but his face remained calm.

His eyes were calm and sincere.

In the end, the one who was defeated first was Jiang Huanxi.

After all, no matter how early she was enlightened and how much she understood, her age was still there.

When it comes to love, she has only had Xu Qingshan. How can she compete with Xu Qingshan, who has lived two lives and is very experienced?
"never mind."

"Baby, if there is anything, you must tell me. Did Tong Tong say something that shouldn't have been said, making you unhappy?"

Seeing Jiang Huanxi raised the white flag first, Xu Qingshan stepped forward, put his arm around the girl's shoulders, and spoke seriously.

"No, no, I just thought that if a younger sister lived in our house, we might feel awkward and aggrieved sometimes."

The girl said in a soft voice.

"By the way, Qingshan, I'll go back to Yandong Garden tonight."

She didn't want to repeat the shameless words of the cold girl on the phone to Xu Qingshan.

Because the girl also said that she was two different people in the eyes of the world and in the eyes of Xu Qingshan.

If I take the initiative to point out her stronger thoughts, I might be the one who gets into an awkward situation.

Jiang Huanxi's mathematical ability is now far superior to that of her counterparts in her previous life. Even if she uses classical probability to determine the expectation of an event, she will never tell Xu Qingshan about their conversation.

"Well, actually she went back at the end of winter break."

Xu Qingshan hugged Jiang Huanxi, patted Jiang Huanxi's shoulders gently and comforted her.

"Besides, she's at the winter camp during the day, so she won't be a problem."

Xu Qingshan bet right on Jiang Huanxi’s idea.

However, rather than being a gamble, it is more like prediction.

"Um"

Jiang Huanxi nodded.

In fact, she still had two exams left and had originally planned to stay in the dormitory for a few more days, but given the current situation, she decided not to back down and went back immediately to have a formal meeting with the sister-in-law with two faces.

She didn't want to be challenged, but now she understood that she must not be afraid of challenges.

She will also be the guardian knight of love!
