Chapter 377 Long time no see, Maxwell
Looking at the entire University of Science and Technology, there are many people who can be called "dean".
After all, including the College of Science and Education Integration, there are thirty full-time deans alone
There are also executive deans, a bunch of associate deans, and so on.
In an informal setting, they can all be considered deans.
But Academician Pan can speak out in this situation, has the ability to influence meetings, and is also the ‘dean’ named Hou.
Then there is one and only one.
That is.
Hou Xingyuan, the former president of the University of Science and Technology and now the president of the Chinese Academy of Sciences!
A man who led HKUST to rise again after the humiliation of Zhu Xshi.
At that time, the University of Science and Technology was in a mess due to its president Zhu Xshi, who had the worst reputation in history. He pursued a policy of contraction. It had the name of a University of Science and Technology, but did not have the reality of being a University of Science and Technology.
And just after this person ruined HKUST and left, HKUST welcomed a president with the highest reputation since the 1990s.
This person is Hou Xingyuan.
What he inherited was a mess filled with the atmosphere of the old era, but what he handed over was a modern university that has caught up with the new era.
During his tenure, he continued to bridge the relationship with the Academy of Sciences, local governments and the Ministry of Education. He also reversed the construction plan of abandoning engineering and mathematics and reduced the wrong policies of various places.
When Xu Yun was studying, Hou Xingyuan had a nickname:
HKUST Guangwu.
This shows how great his contribution and image in the hearts of students are.
Although the president of HKUST has been replaced by another person, Hou Xingyuan's status has never been shaken.
The reason why the fifth-generation imidacloprid developed by Xu Yun was patented so quickly was because Hou Xingyuan was behind it.
Xu Yun kept that incident in mind, wondering if he could repay the favor if he had the opportunity in the future.
As a result, I didn’t expect that I hadn’t had the chance to return the favor to him, and now I had received a huge favor from him?
To know.
The power of the University of Science and Technology mentioned by Academician Pan is obviously not as simple as issuing an announcement.
Perhaps because of the large amount of information, Xu Yun was still a little dazed at this time, and his words were a bit intermittent:
"No. Teacher, why would Dean Hou do this? Isn't this a bit of a fuss?"
Xu Yun's words are really not self-effacing, but judging from the magnitude of this matter, it is obviously not something that would allow a big boss of Hou Xingyuan's level to end personally.
To put it harshly.
That's not how the guardians protect their cubs.
To know.
The exact words Academician Pan just said were Dean Hou's 'instructions', not opinions or ideas.
In other words, Hou Xingyuan did not express his concern in a private capacity, but made some kind of request as the president of the Academy of Sciences. Under normal circumstances, even if the other party pays attention to this matter, the secretary should use a private phone to inform him after get off work. Just give it a shout.
This is the wisdom of avoiding suspicion.
In other words.
Now that Hou Xingyuan has personally come forward to convey the instructions, this can be regarded as the attitude of the Academy of Sciences in terms of party affairs - it is just missing a red-headed document.
But this thing seems very cool, but it is not logical at all.
Even for Meng, who made a big fuss back then, and an academician surnamed Fang who was kissed three times by a woman in blue during an online meeting not long ago, the Academy of Sciences did not express any attitude.
Those people are still like this, let alone Xu Yun, who is just a little transparent for the time being.
Looking at Xu Yun who looked surprised, Academician Pan turned his head and looked at Tian Liangwei, and the two smiled at each other.
Tian Liangwei straightened his body and said to Xu Yun:
"Well, Xiao Xu, the fact that you can ask this question shows that your thinking is still very rational - yes, in fact, based on your size alone, it is not enough for the Academy of Sciences to endorse you."
"It's just that you're pretty lucky this time."
Xu Yun was slightly startled:
"Luck?"
Tian Liangwei nodded without explaining much.
However, what Dean Hou said on the phone slowly emerged in his mind:
"Everyone, now that the world has finally been settled, it's time for some evil spirits and snake gods to be reckoned with."
What Xu Yun didn't know was.
This incident was a catastrophe in his life.
But in the eyes of some senior executives, this is a good opportunity to clean up the dirt on their own homes.
Even Dean Hou, who is standing in the clouds in Xu Yun's eyes, is far from a real chess player.
It's just that due to some well-known reasons, neither Tian Liangwei nor Academician Pan could explain it clearly at this time, so they could only talk about it in a hurry.
Academician Pan then pondered for a moment and then said:
"Anyway, Xiao Xu, try to keep a calm mind these days. The University of Science and Technology may treat you coldly."
"That is to say, public opinion will not only not control the comments, but will even let them ferment. Although this approach may catch big fish, it may be unfair to you personally."
Tian Liangwei on the side also nodded.
As Academician Pan said.
Since Dean Hou made such a phone call, it meant that the superiors had already customized effective counterattack methods - it was not just a simple announcement.
But on the other hand.
Just like many cases of Internet explosions in the past.
At this time, the people criticizing Xu Yun and HKUST on the Internet are far from just those ghosts and ghosts, there are also many netizens who have been led to the rhythm.
Many times, those monsters and monsters actually only guide one trend, and those who really promote the development of the situation are mostly 'natural people'.
The vast majority of these people will change their stance after the turn of events, but there are still some who refuse to accept any explanation.
Therefore, even if HKUST can make a comeback, many netizens are bound to have a negative perception of Xu Yun.
So from a personal perspective, this is really unfair to Xu Yun.
Fortunately, Xu Yun's mentality is pretty good. After all, the response from HKUST has exceeded his expectations.
At this time, he was quite moved by the feeling that "a scholar will die for his confidant". The University of Science and Technology is willing to use the school to refute rumors for him, so it doesn't matter if he suffers a little:
"Teacher, don't worry, I have no problem here. I don't expect to be completely clean after this happened - there are always some people in this world who will judge the so-called 'truth' based on their own perceptions. In their eyes, all self-evident evidence has a dark side.”
Tian Liangwei nodded:
"That's good."
Then Xu Yun thought for a while and asked:
"By the way, teacher, I don't know what the plan given by Dean Hou is."
Tian Liangwei thought for a moment, waved to him, lowered his voice and said:
"At present, we are not sure how much of the plan can be completed in the end. In short, we are prepared to do it first and then last."
The more Xu Yun listened, the brighter his eyes became. By the end, his breathing became heavier.
After leaving the administration building.
Xu Yun returned to his house outside the school alone.
Click——
As a result, I just opened the door.
He then saw Lao Su who was sorting books at the table and obviously about to go out, and quickly said hello:
"Good afternoon Mr. Su, are you going out?"
"Oh, it's Xiao Xu, good afternoon."
Old Su nodded towards Xu Yun, raised the book in his hand, and explained:
"Well, I'm going to the library to read some more books. I've encountered some problems recently and I'm going to look for information."
After speaking, he paused slightly, then glanced at Xu Yun who had already put on his slippers, and said after careful consideration:
"Xiao Xu, I saw a piece of news on that headline today. It seems that you are entangled with a woman."
Xu Yun was stunned for a moment.
Good guy.
Does Lao Su, an electronics novice, know about this?
Then he sighed quietly, but it was inconvenient for him to hold on in front of Lao Su:
"I can't help it. I've been hacked. I'm preparing to fight back."
As a newbie who had just mastered the Jiugongge input method, Lao Su actually didn't quite understand the true meaning of the words "being hacked" and "fighting back."
However, the party struggle in the Northern Song Dynasty was unique in Chinese history, so he quickly understood what Xu Yun wanted to say:
"Are you being splashed with dirty water?"
"Yeah."
Lao Su opened his mouth, but in the end he remained silent.
If this happened in the Northern Song Dynasty, he might be able to help Xu Yun think of a solution.
But now is 2022, a completely unfamiliar era.
Lao Su himself has not fully adapted to modern life, let alone connections.
Seeing that Lao Su was a little depressed, Xu Yun quickly took the initiative to comfort him:
"Su Gong, don't worry. The superiors have already formulated a counterattack plan. Everything is under control. You can just watch the show with peace of mind - by the way, what have you learned recently?"
Old Su shook the book in his hand at him, and this time Xu Yun finally saw the content clearly:
"I'm learning Riemannian geometry. People on the Internet say that this is something you only need to know at hand. You need to master the subsequent theory of relativity to get started."
"."
Looking at Lao Su with a serious look on his face, Xu Yun twitched the corners of his mouth slightly.
He could roughly guess where Lao Su saw the contents
He seemed to see a wall hanging slowly growing under the supervision of some keyboard warriors on the Internet.
Xu Yun then bid farewell to Lao Su and returned to the room alone.
He took off his shoes and socks and leaned back on the chair.
This was also the first time today that he had the opportunity to lean back on the chair and rest peacefully.
After a while.
Xu Yun stood up again, walked to a small box, and took out a cowhide bag and...
A small card.
According to the earlier analysis.
Now he has in his hand the two common cards of Wheat Manuscript and God King, as well as the table-turning king bomb of Gravity Gradiometer.
But now with the intervention of Hou Xingyuan or the Academy of Sciences, Xu Yun's methods are much more relaxed.
At least there is no need for allin to go in.
Likewise.
He was also able to analyze the current situation more calmly, paying attention to some aspects that he had previously ignored.
For example
Since the equivalent of the gravity gradiometer is too large, and the Wheat Manuscript and the God King are relatively mediocre, then.
Is it possible to take a middle value?
Is there a certain achievement that can bring down a large number of official media, but is not so exaggerated that it will lift the table and silence it?
Xu Yun ignored this idea at the time, but now he thinks about it
Apparently it is possible.
For example, the one in front of me——
"Proof of the Existence of Odd and Perfect Numbers".
This manuscript proves that odd perfect numbers do not exist, which means that all perfect numbers are even perfect numbers.
And in the field of mathematics.
When talking about even perfect numbers, we have to mention another concept:
Mersenne primes.
Mersenne primes are a concept of Mersenne numbers.
The so-called Mersenne number refers to a type of number in the shape of 2p-1, in which the exponent p is a prime number, often written as Mp.
If a Mersenne number is prime, it is called a Mersenne prime.
All perfect numbers discovered so far are even perfect numbers and correspond to Mersenne primes one-to-one, without exception.
In other words, there are as many perfect numbers as there are Mersenne primes found.
So all the time.
The question of whether there are infinitely many Mersenne primes has always been one of the famous unsolved problems in number theory.
Or to be more precise.
Whether there are odd perfect numbers is itself a branch problem extended from Mersenne prime numbers.
Until 2022.
Only 51 Mersenne primes have been discovered in the world, and the largest one is M82589933, which is 2^82589933-1.
If "Proof of the Existence of Odd and Perfect Numbers" is a luck-based paper that requires other people at the same stage, that is, within four years, to have a chance to win the Fields Medal
So if the problem of Mersenne primes can be solved, it will undoubtedly be a standard Fields Medal achievement.
Of course.
The premise is that no one has figured out Fermat prime numbers or Riemann's conjecture.
at the same time.
Although the Fields Medal is one of the highest honors in mathematics, its award requirements have an age limit - it is only awarded to 'young people' under the age of 40.
Therefore, compared to the Wolf Prize and the Abel Prize, Fields is relatively younger.
The current youngest winner of the Fields Medal is Jean-Pierre Serre, who was awarded the award at the age of 28.
The Fields Medal is awarded once every four years, and this year’s winners list was released in August.
So in terms of honors, if Xu Yun wins the award, he will have to wait until 2026 to receive the award.
Xu Yun will also be 28 years old by then and will not look out of place at all.
And winning awards and popularity are two different concepts. Even if the awards are not given until 2026, Xu Yun will still receive the necessary reports as long as he publishes the relevant results.
Popularity comes from journals, and honor comes from awards.
This heat is lower than the gravity gradiometer, but higher than "Proof of the Existence of Odd and Perfect Numbers" and the God King.
It is undoubtedly an excellent auxiliary means to cooperate with the next operation of Shanghai University of Science and Technology.
Of course.
The premise of all this is that Xu Yun can prove the infinity of Mersenne prime numbers.
Because of this
This time.
He directly took out Wheat's thinking card.
Considering that I dealt with too many things today, my body is a little tired.
Therefore, Xu Yun was not in a hurry to start 'inviting gods' immediately.
He took a quick shower first, went to bed and took a nap.
It wasn't until about four o'clock in the afternoon that I woke up.
He locked the door and sent Lao Su a WeChat message saying that he didn't need to call him for dinner when he came back.
Then he came to his desk.
Xu Yun had used Mavericks' thinking cards before. As the saying goes, once it's new, it's twice as familiar. This time, his mentality is much calmer.
After everything is ready.
Xu Yun solemnly picked up the wheat thinking card and thought to himself.
"Activate!"
Brush——
The card representing wheat slowly disappeared.
In a certain field of vision that Xu Yun could not see.
A wall of portraits quietly appeared behind him.
The names of countless mathematicians throughout the ages are engraved on the wall, including Euler, Riemann, Dirichlet, etc.
At the bottom is Xu Yun’s junior high school teacher
After a while.
The top area slowly glowed with golden light, and a name quietly emerged in the air:
JamesClerkMaxwell.
After a while.
A slightly pale, thin, middle-aged man with a beard and an ax on his waist walked out.
He stared at Xu Yun for two seconds, and then turned into golden light and flew into Xu Yun's body.
at the same time.
Xu Yun's eyes suddenly cleared up, and he found that his thoughts were broadening again.
A few seconds passed.
He looked at his palm and sighed with emotion:
"Long time no see, Mai."
Then he shook his head vigorously and quickly focused his thoughts on the Gaussian manuscript in front of him.
After hesitating for a moment, he picked up his pen and started writing quickly:
"Solution:"
"Lemma: If n>1, a^n1 is a prime number, then a=2, n is a prime number."
".When n>1, if a>2, then a^n 1=(a1)(a^n-1+a^n2+a^n3++a+1) ”
"It can be seen that a^n-1 is a composite number, so a=2."
"If n is a composite number, n=xy, x>1, y>1, then 2^xy-1=(2^x-1)(2^x(y-1 )+2^x(y-2)+2^x(y-3)++1)”
"It follows that 2^n-1 is a composite number."
Finish writing these.
Xu Yun paused slightly and moved Gauss's manuscript to his hand.
"It can be known from the fact that there are no odd perfect numbers. Suppose the positive integer n has prime factorization n=p^(a1/1)p^(a2/2)p^(a3/3).p^(as/s)."
"Since the factor and function σ are multiplicative functions, then we can get:"
“σ(n)={p^（a1+1/1）-1}/{p1-1}·{p^（a2+2/1）-1}/{p2-1}·{p^（ a3+3/1)-1} /{p3-1}·{p^（as+s/1）-1}/{ps-1}=s∏j1·{p^（aj+j/1）-1}/{pj-1} ”
that's all.
Xu Yun wrote quickly on the A4 paper in an eloquent manner, and time slowly passed by minute by second.
Tower number.
The law of excluded middle.
Single unknown
Xu Yun seemed to have returned to Cambridge University in 1850, when he was sitting at the desk discussing various issues with Xiaomai.
It's just that Xu Yun was the teacher and Xiaomai was the student.
And this time.
Xu Yun became a student and Xiaomai became a teacher.
An hour later.
Xu Yun's pen tip paused slightly and wrote the last line:
"To sum up, there are infinitely many Mersenne primes."
at the same time.
His body was inexplicably shaken.
The thoughts that were spinning rapidly suddenly stopped.
A few seconds passed.
Xu Yun gently exhaled a long breath, filled with emotion and reminiscence.
"Thank you, Maxwell" (End of Chapter)
