Chapter 174 Well, it’s stable
After the two finished eating and sat down, Xu Qingzhou said helplessly: "It seems that there is really no time to move this month."
He went to his new home to clean it up last weekend. He hasn't been there since then and spends all day in the laboratory. Song Yao is still living in the dormitory and occasionally brings some things over to wait for him to move things together.
"I have already laid out the cotton wool. If you are late for the experiment, you can go directly to sleep." Song Yao nodded slightly, knowing that Xu Qingzhou was busy.
Moreover, she likes the feeling of decorating her home bit by bit with her own hands.
Xu Qingzhou clicked his tongue for a while. Is this what it feels like to have a girl by your side? You don't have to do anything, just lie down and enjoy it. You shouldn't say anything, it's a bit refreshing.
"I'm leaving on the 28th. Do you really have nothing to bring?"
Song Yao shook her head: "No."
She didn't say anything, she had everything. He just needed to bring himself back.
"Okay."
Based on Xu Qingzhou's understanding of her, it is estimated that there is really no more.
After dinner, the two of them were not tired of being together. Xu Qingzhou went directly to the library, while Song Yao went back to the dormitory to rest. She had all classes this afternoon.
In the library, Xu Qingzhou opened the document and prepared to write an academic report on Kramer's conjecture.
Reporting formats are similar for Mathematics and Physics.
Explain the concept of Krammell's conjecture, clearly define Krammell's conjecture, give its standard expression, and briefly introduce the mathematical concepts and theories related to Krammell's conjecture.
The most important thing is the methodology part, which introduces in detail the proof methods and ideas adopted. This can be roughly divided into 5 subsections, each section corresponding to a key step or sub-problem.

Next, Xu Qingzhou spent a week writing the report. At the same time, he rehearsed all the questions and difficulties he might encounter to ensure that he could handle them with ease at the report meeting.
During this period, he made a start for his thesis, titled: The Effect of Space Walk-off on the Compression Characteristics of Quantum Optical Frequency Combs.
I’ve written a quarter of it, and I’m going to write the rest when I get back from my business trip.
When I was busy with experiments, papers, and writing academic reports, time seemed to be pressed on the accelerator button. March passed quickly, and it was already March 28th in the blink of an eye.
To be more precise, living together with the school beauty Song was postponed until he returned from a business trip.
Early on the morning of the 28th, in Dormitory 101, Xu Qingzhou packed up his things, said goodbye to his three adopted sons in the dormitory, and set off for the airport.
After being reborn, I went abroad for the first time.
Xu Qingzhou left the dormitory and sent a message to Song Yao who was in class, saying that he was leaving.
Song Yao: "Yeah."
Xu Qingzhou was stunned. He was so cold and seemed really busy.
He stood still, feeling that just walking like this seemed like something he was doing, and planned to continue waiting for news from Song Yao.
Sure enough, the other party's message popped up again: "Be safe and call me when you get there."
Xu Qingzhou nodded with satisfaction, replied "ok", and got on the subway with his suitcase.
At 8:30, Xu Qingzhou was already at Kyoto International Airport. This flight was mainly from Kyoto International Airport to London Heathrow Airport.
Xu Qingzhou had just finished answering Song Yao's call and was about to look at the information on Kramer's conjecture when he received another call from Professor Gu Zhizhong.
"Professor Gu, okay, I know. Contact senior brother Zhao Zhenglai as soon as you get off the plane."
A senior brother named Zhao Zhenglai came to pick him up.
On the School of Mathematics at Beijing University, the person invited to attend this meeting was Academician Xu Shihui, and Zhao Zhenglai is a student of Academician Xu Shihui.
Half a month ago, Academician Xu Shihui brought his students here for exchanges.
At 8:50 in the morning, Xu Qingzhou boarded an international flight to London, starting a long 11 and a half hour journey. The Institute of Mathematics provided ample funding for business class, but Xu Qingzhou could only buy an economy class seat. After finding his seat, he took out the information on the twin prime number conjecture from his schoolbag.
The proof of the twin prime conjecture went quite smoothly, using the sieve method + function model, using functions to make up for the shortcomings of the sieve method.
[Selberg noticed\sum_{d|n}\mu(d)]
[So, when n=1, it takes 1, and it is 0 at other times, so as long as \lambda_1 is not less than 1, the formula of the sixth step determined by any real sequence {\lambda_d} can become the required upper bound .]
By the window, Xu Qingzhou frowned slightly and tapped his arm with his fingertips.
Every time something flashes across my mind, but I can't catch it. It's very similar to the feeling described in the novel of being in the Great Consummation period and about to be promoted.
However, Xu Qingzhou's thoughts were quickly interrupted by the nagging voice of the boy next to him.
The sound came from far to near, and then a strong smell of perfume came, and there was a rustling movement beside him. A girl sat down next to him, and another young man sat in the aisle.
"Xiao Ran, studying abroad is definitely the best choice."
While talking, Sun Qingli glanced at the boy who was reading by the window. He was originally thinking about changing places with Xiao Ran, but he was very unhappy when he saw Xiao Ran sitting next to other boys.
Moreover, this boy is a bit handsome.
But when he saw the other person holding a bunch of messy things in his hands, he felt relaxed immediately.
He knew that what Xiaoran hated were those nerds.
Yeah, solid.
Sun Qingli sat down and said with emotion in his tone, "Nowadays, the environment of domestic universities is not good. All the students they teach are nerds. There is no way to compare with foreign universities."
Hearing this, Xu Qingzhou glanced at him lightly, shook his head, and turned his attention to the information in front of him. There were too many people like this. The moon abroad was always rounder than at home, and he was too lazy to talk about it.
Seeing that the girl next to him didn't answer, Sun Qingli planned to test it out, and then jokingly said: "Why don't you apply to our University of Glasgow, and we can take care of each other."
Zanna was already a little impatient, but she still kept a smile on her face and even nodded from time to time.
This person loves to talk a lot. If traveling alone is not really boring, she really doesn't want to go with him.
"The University of Georgia has recruited a lot of international students in recent years. With your grades, there is no problem at all." Sun Qingli continued.
Ranna could only smile perfunctorily: "Let's talk about studying abroad later. I came out this time mainly to relax."
"Okay, okay." Sun Qingli smiled and nodded. There was still a week left anyway, so there was no rush.
After a while, he looked around at the surrounding environment and said to himself with some regret: "It's a pity that we were in a hurry to buy tickets and we ran out of tickets. Otherwise, we should have bought business class."
"It's pretty good here." Ranna smiled, took out her fruit phone, and prepared to clock in and take photos.
Xu Qingzhou was still thinking about the twin prime conjecture and automatically blocked the noise around him. Suddenly he felt someone poke his arm.
He turned around and saw the girl flipping her hair around her ears and looking at him coquettishly, "Handsome guy, can I change seats with you?"
For such a long trip, Ranna likes to sit closer to the window, which has more space and doesn't have to be too close to Sun Qingli.
She was very confident that the boy in front of her would agree.
Today's makeup took an hour to make. Not to mention such a little brother, even a social creature who has been tortured by society for a long time would not refuse the request of a beautiful sister like her.
As she expected, a warm smile appeared on the boy's face.
"No change."
"Thanks"
Ranna's other word "thank you" was stuck in her throat, she looked at the boy in front of her in astonishment, and a voice came up in her heart: "What are you talking about?"
