Chapter 194: Departure, World Congress of Mathematicians
Langley, a suburb on the border of Virginia and Washington, D.C., USA.

There are two buildings hidden in the bustling commercial district. In a spacious and bright office in the New Headquarter Building on the west side, Director Burns is listening to a report.

"...The Chinese mathematician Qiao Yu you just mentioned solved the Riemann hypothesis, so that's amazing?"

"Yes, the Riemann hypothesis is one of the most important problems in mathematics."

"So will this question have any negative impact on national security? For example, if China has the answer to this question, will it pose some threat to us?"

"Well, in fact, it can't be understood that way. Simply put, the answer to this question is open to the world. The American mathematicians will verify whether the answer is correct. It's just that it has been solved..."

"Oh, of course I see what you mean. He is a theoretical mathematician."

"Yes!"

"Okay, I know that although Johnson is a professional, this issue is not that simple. We don't need to offend China because of a theoretical mathematician.

What they like most is to make their research results public to the world, just like science has no borders, right? So there is no need to be so nervous, just relax. "

"but……"

"No buts. We all know this is not a good time. Of course we can try to persuade him to stay. After all, this is a beautiful country with a freer environment for communication.

So you can think of a solution from this aspect. After all, Qiao Yu is so young, maybe you can find a way to make him understand how wonderful it is here. Don’t you think so? "

"Of course, that's a good idea."

"Let's do it this way." Burns finally nodded and determined the general direction.

He does not need to be responsible for specific matters. In fact, it is the same all over the world. Professional matters are done by deputies.

But he needs to grasp the general direction and constrain those professional deputies. After all, these professionals often don't have much of a big picture view.

Although Burns didn't understand mathematics, he understood the current situation! What a joke? At this time, he was going to anger China for a mathematical genius who was engaged in theory?
Do you really think it's still 20 years ago? He doesn't want to take the blame for such a trivial matter before he even gets comfortable in this position.

Even if we really want to do something, we have to wait until Arlington County can really stand up.

A bunch of pig teammates!

……

China, Beijing.

Qiao Yu really didn't care how Frank was doing or whether he was put on record somewhere.

There was no way, he had been living too full recently and had no time to think about any other messy things.

The accumulated tasks on the Xiyu computing platform have almost been completed. There is still about half a month until the start of the World Mathematical Congress on July 7.

So Qiao Yu thought about going back to Xingcheng again.

After all, I have done almost everything I should do in Beijing, and I have also obtained a visa to attend the World Congress of Mathematicians.

Even if the Xiyu computing platform has not yet fully met the predetermined requirements, that is due to the lack of strength on the part of the Institute of Computing Technology and has nothing to do with him.

It has been a long time since he last visited his hometown, and it was definitely not to return home in glory or to continue his relationship.

The main purpose was to send the manuscript to Zhou Shuang. Not to mention that it was summer vacation now. It was natural for students to go home during the holidays.

The most important thing is that no matter whether it is Yanbei or Huaqing, Qiao Yu feels that he really can't stay there anymore.

Now professors come to visit him almost every day to discuss a variety of mathematical problems with him, such as the future direction of mathematical development under the modal axiom system.

Qiao Yu felt dizzy.

Especially those who deal with partial differential equations, which really makes Qiao Yu speechless. They actually want to transform the solution of partial differential equations into a geometric flow problem on the modal path Γ.

According to these professors, many solutions of partial differential equations can be treated by separation of variables or eigendecomposition methods, such as those based on Fourier or eigenmode decomposition.

In a sense, the generalized modal axiom system provides a natural framework for treating these eigenmodes as basis vectors of the modal space.

In this way, the modal path Γ can be further introduced in theory to quantify the relationship between these modes and even geometrically model the nonlinear terms.

Qiao Yu thought what they said made sense, but the problem was that he had no interest in partial differential equations.

But Director Tian is also a researcher on partial differential equations. So many of the people who come to visit him are his fellow students. These people may help him in the future, so it is difficult to drive them away, and it is a headache to chat with them...

In this case, if he could go home with Qiao Xi, he could successfully avoid these professors with strong thirst for knowledge and have a perfect summer vacation.

All in all, isn't it more comfortable to enjoy Xia Keke's admiring gaze and praise him with the soft and sticky voice of a southern little potato than to be harassed by a group of professors every day?
Unfortunately, Tian Yanzhen rejected him, and his words immediately destroyed all his little thoughts.

"Do you still want to go to the meeting in Philadelphia? Do you still want to collect the bonus?"

"Of course I'm going to go. Maybe I can even win the Fields Medal! My master said he wants to see me win the award in person."

"That's it. You think going to Philadelphia is just a matter of flying there and flying back? You have classes in two days."

"Going to class again?"

"Well, some courses on safety and thinking when going out. Anyway, it's always good for you to learn more."

"Uh... is it similar to the previous confidentiality courses? Is it that Mr. Wen who will teach me again?"

"No. Don't ask so many questions. You will know the day after tomorrow."

"Then can I ask who hired the teacher this time?" Qiao Yu asked.

"Chief Engineer Yu. Your algorithm was mentioned in the report submitted by Chief Engineer Yu. The original words were that the mathematical analysis method you created would greatly speed up the moon landing project.

At the same time, it will have a huge driving force for the future development of China's aerospace engineering and new materials. So when you go to Philadelphia this time, you will not only take safety courses, but you will also have personal protection. "

Tian Yanzhen said casually. Apparently, he was also questioned. He even saw the report from Chief Engineer Yu.

Qiao Yu nodded, and some past events when he had dealt with Yu Yanjiang came to his mind. Although his mentor had told him that this chief engineer was very stingy, this big guy still had good vision.

Well, anyway, learning knowledge in class is always a little more interesting than talking about math with a bunch of professors.

Qiao Yu was deeply impressed by Mr. Wen, the teacher who taught him the confidentiality course. He had profound professional knowledge and could easily cite various cases.

This made Qiao Yu even look forward to the next class. After all, knowing this would give him more topics to brag about with those ignorant guys.

But after thinking about it, Qiao Yu asked seriously, "Well, Director Tian, ​​Chief Engineer Yu, could it be that I might be in danger if I attend a conference?"

Tian Yanzhen answered directly: "Don't worry, your participation in the conference this time was specially discussed in the meeting. Safety considerations should be taken into account, but it is better to take precautions before it happens.

However, if you really make Xiyu Computing Platform famous after you go there, it will be difficult for you to go out next time. So it will definitely be good for you to communicate more in the limited time.

Okay, if you want to go back to Star City, you can wait until you get back from Philadelphia. I'll give you a week off. Go do whatever you need to do. I have to go out later."

Qiao Yu nodded, and his mood instantly improved.

There was even a special meeting to discuss whether he could attend the World Congress of Mathematicians... Well, this probably means that he is a big shot now, right?
"Is there anything else?" Tian Yanzhen asked the student who was reluctant to leave even after being ordered to leave.

"Um... Actually, there's nothing much to say. I just wanted to ask if my security level is quite high now?"

"Just focus on your research instead of wasting time trying to find out about trivial things!" Tian Yanzhen scolded.

"Oh!" Qiao Yu turned and walked out, and the tutor's faint voice came from behind him.

"Your security level this time is higher than that of Mr. Yuan! We have even arranged invisible protection personnel. Are you satisfied?"

Hearing Director Tian's words, Qiao Yu turned his head and glanced at Director Tian. His mood became even more excited.

He hasn't even done any sensitive research yet, but he's already been treated like this! What if he becomes the person in charge of an important research project in the future?

After all, being valued means making more money!
……

Tian Yanzhen was talking about the day after tomorrow, but the next day Tian Yanzhen called Qiao Yu to the office again and introduced two people to him.

From Qiao Yu's perspective, one looked to be an old man about forty years old, and the other was a young man in his twenties.

"Come here, Qiao Yu, let me introduce you. This is Zheng Xiwen, who is mainly responsible for your safety training during this period. This is Zhang Mingyu. They will be with you as ordinary scientific research entourage during the Philadelphia Conference."

As soon as they entered the door, before Qiao Yu could take a closer look, Tian Yanzhen had already introduced the two of them.

"Hello, Teacher Zheng, Hello, Teacher Zhang." Qiao Yu immediately greeted them politely. After all, they were security personnel around him.

"Hello, Qiao Yu. But what Academician Tian said just now is not comprehensive. In fact, it is not just during the Philadelphia conference. From today on, the two of us will be with you all the time."

The older Zheng Xiwen said with a smile. Zhang Mingyu beside him just smiled slightly at Qiao Yu and nodded in greeting.

"Ah? No way? Then where do you live?" Qiao Yu asked with a blink.

After all, the place he lives in now is just a one-bedroom apartment. There is really no place for two people to stay.

"It's okay. Your room downstairs has been cleaned up. We will live downstairs during this period. You don't have to feel uncomfortable. We won't interfere with your daily life.

It's just that we can get to know each other more easily after a period of time. It will also help you get used to dealing with us after you go abroad. "Zheng Xiwen explained with a smile.

Qiao Yu asked, "Oh, so, Director Tian said I still have to attend classes? Are there fixed times for classes every day?"

"It's not that troublesome. Our classes are very flexible. As I said before, it all depends on tacit understanding. There's still half a month left, so we just need to communicate on a daily basis."

In fact, as long as you cooperate with us, other problems will not be a big deal. Many things in this regard cannot be taught in class, they are mainly learned in life. "

Zheng Xiwen explained with a smile on his face.

Qiao Yu felt that Teacher Zheng completely overturned his stereotype about personnel arrangements.

What a kind person! He looks harmless. Who says security guards all have stern faces?
The younger teacher Zhang was always very serious and stern, but the two of them obviously focused on teacher Zheng.

After a few more pleasantries, Tian Yanzhen said, "That's it. I'll leave Qiao Yu to you two from now on."

Then Tian Yanzhen looked at Qiao Yu again and said seriously: "Qiao Yu, safety issues are no joke! You must listen to Teacher Zheng and Teacher Zhang."

"Don't worry, Director Tian, ​​I understand."

……

"Teacher Zheng, Teacher Zhang, do you know Teacher Wen who taught me confidentiality class before?"

"Teacher Wen? Then we may not know each other. But the teacher who can teach you confidentiality may not tell you anything other than what is in the class. Including your last name."

"So that's how it is! That's why I couldn't find anyone anywhere!" Qiao Yu nodded.

"By the way, Mr. Zheng, when Mr. Wen gave me a confidentiality class, he talked about many cases where scientific researchers were negligent or bribed by spies.

Now that you are here to help me, if I really encounter someone sending me a sugar-coated bullet when I go abroad this time, can I eat the sugar coating and send the bullet back? "

Tian Yanzhen just made a casual introduction, and it was obvious that the two teachers had not yet realized that they had met a talkative mathematician who could subvert their beliefs in life.

This mathematician is still so young that it is easy for people who have experienced it to think that he can still be saved.

So Zheng Xiwen asked seriously, "Why don't you be more specific? What do you mean by sugar-coated bullets?"

"For example, let me give you an example. If I go to the Mathematicians' Conference this time and fool around with something, someone with bad intentions will come out and throw dollars at me and ask me to help them with a project or something.

I will first find a way to collect the money, and then when I come back with you, I won't do anything for them. Do you think this will cause any trouble?"

Qiao Yu asked innocently.

Zheng Xiwen and Zhang Mingyu looked at each other and suddenly felt that their work seemed a little tricky.

"Why do you have such an idea?" the young man finally couldn't help asking.

"Don't you think that earning US dollars and spending RMB can make people happy physically and mentally?" Qiao Yu asked in surprise.

"Didn't we say before that we still have to go to class? Why don't we start with the properties of money?"

Zheng Xiwen took over the conversation.

Qiao Yu hesitated for a moment and asked, "Um, Teacher Zheng, you're not trying to tell me that money isn't that important, are you?"

Zheng Xiwen shook his head and said seriously, "No, I want to teach you how to have endless money."

Qiao Yu smiled and asked again: "Teacher Zheng, do you have endless money?"

Zheng Xiwen shook his head and answered honestly: "No!"

But then he changed the subject and said confidently: "But I didn't because I didn't have the ability. You are different, Qiao Yu! With your ability, after listening to my class, I guarantee that money will be just a number to you in the future."

Qiao Yu blinked and asked, "Before the age of thirty?"

Zheng Xiwen asked back: "You are only seventeen years old this year, right?"

Qiao Yu nodded.

"Then why are you so reserved? Has your mathematical research hindered your imagination? Be bold! Before you are twenty-five!"

Zheng Xiwen waved his hand like a general and spoke majestically.

Qiao Yu's eyes lit up and he looked at Zheng Xiwen as if he was seeing the good old man from two years ago.

He was only fifteen that year. It was also the first time in his life that someone told him that as long as he studied math well, his future would be limitless. He would definitely make a lot of money!

"Teacher Zheng, no wonder I felt that you must be a capable person the moment I saw you today. Apart from anything else, you are so accurate in judging people!"

On the other side, Zhang Mingyu silently watched the two and listened to their bragging. How should I put it, being assigned to work under Brother Zheng can really help me gain some different insights.

……

With two more people around him, Qiao Yu's life in Beijing didn't change much. Many professors still came to visit and discuss things with him every day.

There is even a trend of expansion. Before, it was only professors from Huaqing and Yanbei. Now, professors from many surrounding schools will also take time to come and chat with Qiao Yu.

This kind of academic discussion would take up about half of his working time every day. In the remaining time, Qiao Yu would study data calculations and guide Brother Chen's progress.

Yes, Chen Zhuoyang's work is still in progress.

Although the Riemann hypothesis has been proved in a simpler way, it can be proved again in a slightly more complicated way. This is also valuable.

For example, the old method may reveal some hidden mathematical structures to enrich his generalized modal axiom system.

The worst case scenario is that we can prove it once more and make everyone happy again.

Qiao Yu had already thought of the lines for the 7 o'clock news: "Under the guidance of world-renowned mathematician Qiao Yu, a member of Qiao Yu's research team and a young Chinese mathematician, Chen Zhuoyang, used a new method to prove the Riemann hypothesis once again..."

Just think about it, if this news gets out, how many talented people will put aside their pride and try their best to join his team in the future? Qiao Yu simply can't imagine it!

In other words, Qiao Xi was too disappointing and refused to take the job no matter what; and Old Xue was too proud and was determined not to snatch something that others had already done halfway, otherwise, this huge wealth would definitely not have fallen to Senior Brother Chen this time.

Really, Qiao Yu really felt that Chen Zhuoyang's luck had become incredible since he met him, and all good things could happen to him.

However, when Qiao Yu calmed down and thought about it carefully, it seemed that Senior Brother Chen's luck in the past was actually not bad. He was admitted to a 985 university after graduating from high school, successfully went to graduate school, and even had an academician as his supervisor.

Although I suffered a lot of setbacks during my doctoral studies, which was quite pitiful, I was recruited by Director Tian when I was about to graduate.

Although he encountered some setbacks after going to Tianjin University, his research results helped him to get into a better school and become an associate professor.

Although he has been single, he suddenly fell in love with a girl, and they actually hit it off. The girl is five years younger than him!
He had originally intended to keep the results for himself, but due to some strange combination of circumstances, they were solved ahead of time. There was no point in him brushing up another Glory, and the preliminary work happened to be done by Senior Brother Chen...

After careful consideration, Qiao Yu suddenly thought that there was a possibility that Senior Brother Chen was the one who had the template of the protagonist and won all the way without any effort? His luck was so good that he even felt a little jealous.

I’ll have to ask Brother Chen to try to buy the lottery tickets later, and if he wins, all the prizes must be confiscated!

Apart from thinking about these random things, the rest of the time was spent chatting with Teacher Zheng.

I have to say that Lao Zheng is really good at talking. After spending half a month with Lao Zheng, Qiao Yu didn't even feel that he was a 40-year-old old man, but someone of the same age as him.

Sure enough, the so-called generation gap is fake. The real thing is that we are too lazy to lower ourselves to communicate.

Otherwise, how could Lao Zheng, who is already 40 years old, still be able to chat with him so well and brainwash him crazily without him realizing it...

So comfortably lying on the plane to Philadelphia, Qiao Yu asked Zheng Xiwen very seriously: "Old Zheng, let's talk about something real on the plane. You used to work in MLM, right?"

"Don't talk nonsense. If those who do pyramid schemes can have my skills and ideological awareness, what will happen?"
