Chapter 274 Junior Brother, do you want to climb the mountain together?
The dusk was deep, and the bright moonlight hung down from the sky, blending with the lights of the small town. The streets were quiet, and only a few tourists could be seen occasionally.
A cool breeze blew, which made Xu Qingzhou's drunkenness dissipate a lot. After crossing the road, he called Song Yao: "Good morning."
"You haven't slept yet?" Song Yao's voice was cool and refreshing.
In Switzerland, it is already 12: in the morning.
Xu Qingzhou smiled and said, "No, I went out to drink with Senior Brother Zhang. He and his friends were having a second party, so I was ready to go back."
In the bedroom, Song Yao leaned against the head of the bed, her white and tender feet swaying gently, revealing a porcelain-like luster in the morning sunlight. It was a pity that Xu Qingzhou didn't have the pleasure to see it, otherwise he would have called her "Jade" again.
When Song Yao heard her boyfriend say that they were going out for drinks, she didn't think much about it. Although Xu Qingzhou liked to be flirty, he was only flirty with her. He usually handled things calmly and steadily and would not do anything out of line.
On the contrary, she is more concerned about Xu Qingzhou's safety. She said "um", paused, and reminded: "You are alone, be careful."
"The security here is good, and the bar is not far from where I live. I can see the hotel now."
The two foreign lovers chatted about their experiments and family matters.
Zhang Junli made breakfast and brought out the dumplings. Seeing her husband alone in the living room, she was surprised: "Xiaoyao hasn't woken up yet?"
Song Shisong said helplessly: "I just heard someone talking inside, probably talking to Xiao Xu on the phone, let's eat first."
"Today's young people."
Zhang Junli shook her head, sat down, glanced at her daughter's room, and said with emotion: "If it was a year ago, I would never have believed that Xiaoyao would be in a relationship and spend all day with her boyfriend."
Song Shisong also had the same feeling of trance. No matter how he looked at it, his daughter didn't seem like the type who would fall in love early.
In their imagination, Xiaoyao would graduate from college, go on to graduate school, and then to a doctorate. During that time, she would go abroad to study, come back to find a stable job, fall in love, get married, and start a family.
Now, look what happens. She’s only a freshman and she’s already found a boyfriend.
Song Shisong chewed his dumplings and said, "That stinky boy Xu Qingzhou got a good deal."
Xu Qingzhou is indeed a perfect candidate for a son-in-law, but in his old father's eyes, his own cabbages have been taken away, and Xu Qingzhou is at most a better "pig".
What reassured them was that both Xu Qingzhou himself and the old Xu couple were doing fine.
"How long will it take for Xiao Xu to come back?" Zhang Junli was concerned about her daughter's happiness.
"Just ask my daughter and you'll know."
Xu Qingzhou returned to the hotel. Song Yao told him to go to bed early, so they ended the call. He drank some wine, and coupled with the tiredness from the recent period of time, he felt sleepy as soon as he touched the bed, and his consciousness quickly became chaotic.
When Xu Qingzhou woke up, it was already 8: in the morning.
I opened the curtains and saw a clear sky. The brilliant sunshine fell on the Alps in the distance. The lake was rippling, quiet and peaceful.
After sniffing the smell of alcohol on his body, Xu Qingzhou went into the bathroom to take a shower before going to have breakfast.
In the restaurant, I actually met Zhang Changqing who had gone to learn a foreign language last night.
Zhang Changqing had two dark circles under his eyes and looked more tired than usual at work. When he saw Xu Qingzhou, he teased, "Junior brother, did you have a romantic encounter last night?"
"Brother, I am a family man."
Xu Qingzhou smiled and shook his head, lamenting how all of his fellow brothers were playboys.
"There are too many bachelors around me, and I accidentally included you in the list."
Joking aside, Zhang Changqing was thinking, "If you have such a good girlfriend but are still greedy and have affairs with other women outside, then you are really not a human being."
Xu Qingzhou smiled and said nothing. This was a matter of principle and bottom line, and he would never touch it. Besides, he valued his life and didn't want to be beaten to death by Song Xiaohua. "Let's go to the CMS experimental base first. I have nothing to do in the afternoon." Zhang Changqing thought about it and had a new idea for the afternoon arrangement: "Junior brother, do you want to climb the mountain together?"
"."
"No, I'd better rest in the hotel."
"Come along, I'll bring my camera with me, and we'll take some great pictures."
"Thank you, Senior Brother. I still need to calculate something."
With a camera, the scene becomes even more similar.
"alright."
After breakfast, Xu Qingzhou and Zhang Changqing went back to their hotel room to pack their luggage. At 10 ., Xia Guo's team took a car to the CMS experimental base in Cechy, France.
The circumference of the LHC hadron collider is about 27 kilometers, and the four experimental bases are located in a circular orbit, not far from each other.
The 18th is still a holiday, everyone can move freely, and Academician Yang will organize a dinner in the evening.
Xu Qingzhou had no idea about going out to play, so he declined Zhang Changqing's invitation again and went back to his hotel room alone to look at the information Professor Gu gave him.
There is a lot of information, most of which are the latest papers released by major research institutes in the past two months. He also reads the interesting ones.
These papers did not make much substantive progress. Many of them simply adjusted the sieve method of his twin prime theorem, but they did not go beyond his predetermined framework.
After lunch, Xu Qingzhou began to formally calculate the Polignac conjecture.
How to perfectly combine harmonic number sequences and the sieve method may be the biggest problem he has encountered since he came into contact with the Polignac conjecture.
But the obstacles encountered in solving the Cramer conjecture and the twin prime conjecture are somewhat different.
This time, I feel like I can see the end.
There are four sheets of manuscript paper side by side on the table.
This is the useful information he has filtered out from the calculation manuscripts he has been working on for more than half a month.
A set that can filter out composite numbers and retain prime numbers, the prime number operator P1.
According to the calculation on page 5, this actually satisfies a special proportional relationship: (π(x, x)xeγ2π(Px, x
If we introduce π(x, z), we should be able to get some conclusions about the distribution of prime numbers, namely, π2(x, z)=#{n≤x:(n, Pz)=(n+2, Pz)=1},,,
Obviously, for all p≤z, n belongs to the right set and satisfies the following congruence relation: {n≠0(modp)n≠2(modp)
Xu Qingzhou's gaze paused, his brain working rapidly. That is to say, for all 3≤p≤z, there are only p-2 equivalence classes in the n modulo p complete residue system that can be counted by π(x, z).
This means that when n≤Pz, we have:π2(Pz,zp≤z(12p)
At this point, we can come up with the characteristic asymptotic function, which is equivalent to the lubricant when combining the sieve method and the harmonic series.
With ideas in his mind, Xu Qingzhou picked up his pen and started calculating on a new manuscript paper.
At 6 o'clock in the evening, after Xu Qingzhou had simply packed up, he went out to the restaurant booked by Academician Yang. Zhang Changqing had already arrived and asked Xu Qingzhou to sit next to him.
The group did not exchange too many formal words. Academician Yang said a few opening words and then went on to eat. There was a party atmosphere without those bloody face-slapping scenes.
Everyone was very enthusiastic about Xu Qingzhou.
To a certain extent, it can be said that this victory was achieved thanks to Xu Qingzhou's efforts to turn the tide.
As for Wang Qiming, his previous unhappiness was gradually dissipating. After all, the other party's strength was there, and if he went up to cause trouble, wouldn't he be a fool?
