The top student must be diligent.

Chapter 156: Report in front of thousands of people
"Hey guys, here I come again!"

On Weibo, in the live broadcast room of [Major Mathematical Events].

Blogger Guo Xiaoming was seen standing in front of a building with his arms open, shouting at the netizens coming into the live broadcast room.

His face was full of smiles, as if he was showing off something.

Netizens who entered the live broadcast room started to post comments.

[Isn't this the Great Hall of the People? ]

【Why is the blogger here in the Great Hall of the People? 】

[Is it you? Damn it, you deserve to die! ]

[What what what? Why should the blogger die? What happened? ]

[Don't you know that tomorrow, Xiao Yi's Goldbach conjecture report will be held in the Great Hall of the People? What do you think the blogger is doing here all of a sudden? ]

【what? 】

【what? 】

[You deserve to die! ]

……

Seeing the jealous faces in the comments, Guo Xiaoming smiled and said, "I can't help it. I was lucky. I just grabbed the tickets online and got them. Don't you guys get any? No way, no way?"

After hearing this, the faces of the netizens in the live broadcast room suddenly turned black, and then the content of the barrage became [Unfollow, unfollow], [Leave, unfollow and block], [Never follow this blogger again] and so on.

This kind of threat was quite effective. Guo Xiaoming was immediately frightened and his face turned pale. He quickly said, "Fuck, dads, this wave is mine. I kowtow to you!"

After a long series of apologies, the situation was finally reversed.

[Look how scared the child is]

Guo Xiaoming breathed a sigh of relief and then said, "Anyway, I am quite lucky, probably mainly because I do have a master's degree in mathematics."

Another netizen expressed dissatisfaction in the barrage: [I haven’t even gotten a PhD from Imperial College London, so I have to unfollow him.]

"Brother!" Guo Xiaoming said quickly, "Don't bother with me."

"Maybe God thinks you are gifted and there is no need to waste time attending this lecture."

[But I have decided to watch the entire live broadcast tomorrow, and I study number theory, so it would be very meaningful for me if I could go to the site to watch the report.]

"Uh..." Guo Xiaoming was silent, "Well..."

The netizens in the live broadcast room started to laugh.

【I told you not to talk nonsense! 】

The netizen posted another comment at this time: [How about you give me your qualification? ]

When Guo Xiaoming heard this, his face suddenly turned serious and he said, "Why don't you just unfollow me? This is definitely not an option."

The netizens in the live broadcast room were even happier.

[Blogger: We are just netizens, but you want to kill me? ]

[How presumptuous! Too presumptuous. ]

[You are trying to seize my property, that's very evil]

……

"Ahem." Guo Xiaoming returned to the topic at this time: "Okay everyone, today's live broadcast is mainly to talk about the news I heard about tomorrow's report meeting."

"Everyone should know that this lecture will be held in a 10,000-person auditorium that can accommodate up to 10,000 people. However, I'll share a little tidbit with you. If the seats are not full, there will still be a chance to be let in. So, you understand!"

He raised his eyebrows and said.

Netizens immediately understood what he meant. After all, there were 1 people, and there would always be some people who had something to do on that day or for some other reason, which would cause seats to be vacant.

"Also, even if the place is really full, the organizers should still let in some people as appropriate. Of course, these people can only sit in the aisles or something like that."

"But it doesn't feel bad, it's all good."

"Of course, I have to say that if you really decide to attend the lecture, you have to be prepared to not understand anything. I can only say that for more than 99% of people, it's basically just a fun thing to do."

Guo Xiaoming smiled and said, "But, after all, it is the Goldbach conjecture. Mr. Chen Jingrun's regret has been solved. It's just a pity that he can't see it anymore."

[I heard that Mr. Chen’s descendants will be there]

Some comments mentioned this matter.

Guo Xiaoming raised his eyebrows: "This is very likely, no, it should be said that it is 100% possible."

"After all, so many leaders will come." Guo Xiaoming said, "In addition, some foreign mathematicians also flew here because they don't want to miss the Goldbach conjecture report."

[Foreign mathematicians are coming too? Will the lecture be in Chinese or English? ]

[Will we use English to cater to those foreign mathematicians? Who would understand that?]

Guo Xiaoming smiled and said, "Don't worry about that. When the time comes, Xiao Shen will definitely give his report in Chinese. Almost all the audiences are Chinese. There is no way he will speak English."

"I heard that this incident has caused quite a bit of controversy abroad. Many people abroad think that the Goldbach conjecture report conference should be more international."

"Well now, they can only wait until the report meeting is over and read the translated version."

[Good! Xiao Shen is awesome! ]

[That’s how it should be! The audience are all Chinese, so the report should be made in Chinese! ]

But at this time, someone expressed a different opinion: [Anyway, it’s okay for this kind of thing to be more international, and it’s normal to use English. I think it’s best for Xiao Yi to use English when he gives his report. There are so many academic reports in China, and many people use English.]

This barrage immediately caused many other netizens to curse.

Guo Xiaoming shook his head and said, "That's not the case. This lecture was originally held in China. Although some scholars do speak in English when they hold lectures in China and the audience is all Chinese, you have to understand that this lecture is now held in the Great Hall of the People, and the audience is basically all Chinese. If you speak in English, do you think it's okay?"

"Besides, internationalization is not the same as not having internationalization. The paper has already been sent to the Annals of Mathematics. Do you still say that this is not internationalization?"

"It's not that lectures can't be translated. For example, when Grothendieck was alive, he did not allow publishers to translate the book Principles of Algebraic Geometry, also known as EGA. You see, Grothendieck was not very international."

"Am I right?"

[I learned something new. EGA didn’t even allow the publication of translated versions back then? 】

[No wonder, I have never found the EGA translation before 2015, only the French original. Grothendieck is indeed a stubborn old man as rumored]

[You may not believe it, but in his later years, Grothendieck began to believe in the gods and even wrote a paper to explain the existence of dreams, saying that it was because of God.]

[Ah? Is this true or false?]

……

The live broadcast room started talking about Grothendieck, and the person who claimed to be internationalized probably left the room in embarrassment.

At the end, Guo Xiaoming said: "In fact, the most interesting thing about this report is that it is Xiao Shen's graduation defense. According to the defense committee published online, there are five academicians. It's really awesome."

"And there were tens of thousands of spectators... Damn, if this was the case when I defended my thesis, I don't know how nervous I would be."

"I'm already looking forward to tomorrow."

"You can continue to follow me tomorrow. I will broadcast a text live broadcast like I did during the Twin Prime Conjecture report. If you don't understand what you see during the official live broadcast, you can come and watch me. I will try my best to explain it."

However, he suddenly changed the subject: "Of course, I may not understand, so everyone just pray for my good luck."

……

The next day, May 5th, arrived.

At around 8 o'clock in the morning, there were already quite a lot of people standing outside the Great Hall of the People.

How to ensure the orderly progress of tens of thousands of spectators is indeed a question worthy of discussion. However, for the staff of the Great Hall, this is not difficult, after all, they have seen it many times.

For many people, it was their first time to come to the Great Hall. Looking at the square and solemn building in front of them, they took photos to commemorate the occasion.
In the past, we had seen videos and photos of big guys like Old Ma Ge and Little Ma Ge queuing up to enter the Great Hall. I didn’t expect that they would have such an opportunity this time.

In this way, teams of people finally entered the Great Hall, and were then guided into the auditorium that could accommodate 10,000 people.

Looking at this auditorium that often appears on news and television, everyone feels quite curious.

And if you have some knowledge of architecture, you will be even more surprised at how such a spacious hall can be built without even a pillar?
As for the front, that is, behind the rostrum, it is not the combination of the red flag and the national emblem, but a large screen showing the official theme of this lecture.

[Goldbach's conjecture report meeting and Xiao Yi's undergraduate graduation defense meeting].

……

"They actually included the graduation defense meeting..."

In the backstage, Xiao Yi was staying here and did not go out.

Looking at the words displayed on the big screen outside, he felt a little ashamed.

Isn't this a bit too ostentatious?
"Haha, this is exactly the feeling I want!"

There was a middle-aged man next to him, who said to him with a smile.

"It shows the excellence of our Chinese talents. Their graduation defense used the Goldbach conjecture as the theme, and it was just an undergraduate graduation defense."

This middle-aged man is the director of China's Science and Technology Bureau, Liu Cong.

The Science and Technology Bureau naturally has a very high status in China's academic circles, and they are in charge of anything related to science and technology.

And a report like Xiao Yi's is also inseparable from the support of the Science and Technology Bureau.

This was the first time that Xiao Yi met Director Liu today, and he had a pretty good impression of him.

Hearing what the other party said, Xiao Yi said helplessly: "It feels... they are all about the same."

Liu Cong smiled and patted his shoulder, "Be more confident, it won't be a problem even if you are more high-profile."

"It is a great fortune for our country's basic science to have young people like you."

Xiao Yi waved his hand modestly: "I didn't do anything."

"Don't underestimate yourself." Liu Cong smiled, then he looked at the time: "It starts at 10 o'clock, there is still an hour."

He patted Xiao Yi on the shoulder and said, "I look forward to your performance from now on. There are still many leaders who are paying attention to your report. After the report is over, come over again. There will be a surprise."

Xiao Yi was a little curious, surprised?
But he didn't ask any more questions, because he would know after the report was over. He turned around and looked at the increasing number of people outside, feeling a little emotional.

With 10,000 people, after this report, attending other reports in the future, even a one-hour plenary session of the International Congress of Mathematicians, will probably only be considered a small event, right?
……

An hour passed quickly.

The auditorium was already full of people. Similarly, just as Guo Xiaoming said, the organizers also let in some spectators who came to try their luck at getting in, so that there were quite a few people sitting in the aisles and corridors.
As the time drew closer for the lecture to officially begin, the auditorium gradually became quiet, and there was no need for a host to control the situation.

Of course, there must be a host, who is the dean of the Institute of Mathematics, Academician Xi Lan, who is also a member of the defense committee.

The five academicians of the defense committee were all sitting in the first row. Sitting in the middle was Academician Hu Guangde, who was also the chairman of the defense. After all, Xiao Yi was a student of their USTC after all, so of course someone from their USTC had to serve as the chairman of the defense.

As the time reached 10 o'clock, Academician Xi turned around, stood up, faced the audience, picked up the microphone that had been prepared, and said: "Welcome everyone to the Goldbach conjecture report meeting and Xiao Yi's undergraduate graduation defense meeting."

"I am the chairman of this defense committee, Xi Lan."

"The history of the Goldbach conjecture is very old in the mathematical community. It has a profound significance for the development of the entire mathematical community. After it completely stumped the great mathematician Euler and he spent his entire life trying to solve it, it completely inspired the mathematical community to study the prime number problem. Later, it even indirectly led to the proposal of the Riemann hypothesis..."

……

Academician Xi began his speech for this report.

Backstage, Xiao Yi also tidied himself up and stood in front of the mirror looking at himself.

Just now, the makeup artist did some makeup for him. Of course, it was not heavy makeup, but just simple eyebrows, eyeliner and so on to make him look more mature.

In addition, what he wore today was not a suit, but a Zhongshan suit. Someone measured him some time ago and had it tailored by a domestic Zhongshan suit master. It fit him perfectly.

The style is also very traditional, and there are even buttons on the collar.

"Dude is pretty handsome."

Looking at himself in the mirror, Xiao Yi thought a little arrogantly in his heart.

"Xiao Yi, you can get ready to go on stage."

At this time, Liu Cong called him.

"Ok!"

Xiao Yi responded, then left the mirror and turned towards the exit.

……

"... Then let's welcome Xiao Yi with applause to give us a report on the Goldbach conjecture!"

Academician Xi Lan had just finished his speech and then burst into applause.

In the auditorium, applause from tens of thousands of spectators also rang out, and due to the special acoustic structure of the auditorium, it seemed particularly clear.

Likewise, tens of thousands of eyes looked towards the entrance.

Xiao Yi stepped out.

The Zhongshan suit made the Chinese people present at the scene light up. Although Western suits have been accepted by China and have become formal wear in many occasions, the Zhongshan suit still has an irreplaceable position in the hearts of the Chinese people.

Some elderly people at the bottom couldn't help but smile and say, "What a handsome young man."

Xiao Yi naturally could not hear the words that followed. He walked to the center of the rostrum, faced the people present, and bowed slightly.

Then he raised his head and looked at the many pairs of eyes present.

Ok……

He is not feeling nervous at all, and now he is calm and relaxed.

Then, he said, "Hello, distinguished audience and defense teachers, I am Xiao Yi."

"Thank you all for coming to my presentation, which is also my graduation defense meeting."

"As for the topic of this report, I believe Academician Xi has already explained it in great detail, so I will not elaborate on it in detail."

"Then let me start my report directly."

Afterwards, Xiao Yi walked to the podium at the side and operated the computer on it, and the PPT on the large screen behind him immediately turned a page.

“For all even numbers greater than two, can they be written as the sum of two prime numbers?”

"Here, we first introduce the conclusion of Mr. Chen Jingrun about 50 years ago, Chen's Theorem."

The report officially began, and Xiao Yi first quoted the conclusion of Chen's theorem.

This also attracted the attention of the audience.
In a seat in the second row of the audience, the old woman clenched her hands. On the table in front of her was an old photo frame. The person in the frame was facing the podium.

Next to him, the old woman's son watched this scene, and reached out to fiddle with the photo frame, allowing the person on the podium to have a clear view of what was on the podium.

In addition to them, many elderly people also sat up slightly straighter. For them, the Chen Theorem mentioned now was the proudest achievement of their old friend.

……

Only Xiao Yi's voice was left in the whole venue. People were listening attentively. At the beginning of this segment, Xiao Yi still tried his best to explain the reason of Chen's Theorem to the audience in the form of storytelling.

However, this way of storytelling will eventually come to an end.

"However, Mr. Chen's conclusion also proved one point, that is, it was completely impossible to solve the Goldbach conjecture with the mathematical theory at that time."

"That is to say, the mathematics community needs new mathematical tools to have a chance to completely solve the Goldbach conjecture."

"It is hard to imagine that such a problem that has existed for hundreds of years still has no suitable tools to solve it."

"But fortunately, such a tool finally appeared."

Xiao Yi introduced it a little shyly: "This method is called parity check classification sieve. This method comes from the paper I proposed to prove the twin prime conjecture."

"The Sorting Sieve is a very good judge of the distribution of prime numbers, and it has good applicability to any prime number problem."

"However, the sieving method alone is not enough. For example, in Mr. Chen's method, he also applied the circle method."

“The circle method and the sieve method seem to be two completely different methods.”

"It's just that, for mathematics, trying to connect different things is what many mathematicians do."

"So, my most important work is to combine the sieve method and the circle method to make them a more powerful tool for solving prime number problems."

“And how to try to combine the two is also a difficult problem.”

"In this process, I used the technique of Shaw polynomial expansion - well, this method is also named after me."

Xiao Yi explained again, slightly embarrassed.

This caused everyone present to smile slightly.

"Then, next, I will formally begin to deduce this process."

Turning around, Xiao Yi started writing on a small blackboard next to him.

【(log x)2xε(J(2A)w + J11/6τ 1/2……】

Finally, their report finally reached a professional level.

…

Sitting in a seat on the second floor, Guo Xiaoming was doing a live text broadcast on his mobile phone.

[Hahaha, I don't know if you saw it, but Xiao Shen, this B pretender, the classification screen is his, and Xiao's expansion is also his. But then again, Xiao Shen's report is too kind, I can actually understand what he is saying now. ]

Click Send.

Then when he looked up again, he saw some inscrutable mathematical derivations written on the blackboard.

After being stunned for a moment, he could only lower his head and send a new message: [I was wrong. Xiao Shen’s mercy has ended.]

If the previous difficulty was limited to the level of popular science, just like the reportage "Goldbach's Conjecture" that year, then the next step was to enter the real mathematics profession.

Confused faces began to spread throughout the auditorium.

Only a few mathematicians can barely understand it.

Among them, there are also some foreign mathematicians. These mathematicians dare to come and listen to Chinese reports because they all know some Chinese. Otherwise, no one would torture themselves to listen to a report where they can't even understand the language.

And just like that, time passed quickly.

……

"…Finally, we have succeeded in combining the circle method and the sieve method, using the Xiao expansion as a bridge to combine these two seemingly unrelated methods into a theory, as I explained in my paper, which I named the circle method expansion."

Finally, after some complicated deductions, Xiao Yi turned around and looked at the many confused audiences in front of him. He smiled and was not surprised by this.

"Although I haven't conducted in-depth research, I think this method can be used to solve many other problems, and I am looking forward to the related results in the mathematics community in the future."

"Then..." Xiao Yi paused and said, "Next, it's time to formally solve the Goldbach conjecture."

“I’ll be a little faster.”

Then he began to write quickly on the small blackboard.

At this speed, even the mathematicians who had just begun to understand it began to have trouble keeping up.

In the end, they had no choice but to give up.

Anyway, for the following derivation process, you just need to understand the original text of the paper, although there are quite a lot of amazing ideas in it.

Of course, it was enough to listen carefully to Xiao Yi's theoretical explanation of the Circle Method.

As Xiao Yi said, the theory of circle expansion will be able to be used to solve many other mathematical problems.

Hu Guangde took off his glasses and leaned back in his chair.

Xi Lan beside him also gave up, turned around to look at Hu Guangde, and asked, "So, after Xiao Yi graduates, where will his graduate studies go? What do you guys say?"

Hu Guangde shrugged and said, "Who knows? Although many schools around the world have sent us emails, it seems that Xiao Yi is... planning to study in China?"

Xi Lan's eyes suddenly lit up: "Why not... let him consider our Institute of Mathematics?"

Hu Guangde immediately narrowed his eyes and looked at Xi Lan, "Good fellow, you are waiting for me here?"

However, he finally shook his head and said, "You can ask Xiao Yi when the time comes. Only he can decide on this matter."
