Chapter 174 Yes, stable After they finished their meal and sat down, Xu Qingzhou said helplessly, "It seems that we really don't have time to move this month." He went to the new house to clean it last weekend, and he hasn't been there since then. He spends all day in the laboratory. Song Yao still lives in the dormitory and occasionally brings some things over and waits for him to move together. "I have already laid out the cotton wool. If you do experiments late next time, you can go over and sleep there directly." Song Yao nodded slightly, knowing that Xu Qingzhou was quite busy. Moreover, she likes the feeling of decorating the house bit by bit with her own hands. Xu Qingzhou smacked his lips. 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. It feels good. "I'm leaving on the 28th. Don't you really have anything to bring?" Song Yao shook her head: "No." She had nothing to say, she had everything. He just had to bring herself back. "alright." Based on Xu Qingzhou's understanding of her, it is estimated that she is really gone.
After dinner, the two did not stay together. Xu Qingzhou went directly to the library, while Song Yao went back to the dormitory to rest. She had classes all afternoon. In the library, Xu Qingzhou opened a document and prepared to write an academic report on Cramer's conjecture. The reporting format for mathematics and physics is similar. Explain the concept of Cramer's conjecture, clearly define Cramer's conjecture, give its standard expression, and briefly introduce the mathematical concepts and theories related to Cramer's conjecture. The most important part is the methodology, which details the proof methods and ideas you use. It can be roughly divided into 5 sections, each section corresponding to a key step or sub-problem. [This paper reports a proof of a long-standing unsolved problem in mathematics, the Cramer conjecture. Since it was proposed, the Cramer conjecture has been a hot topic in the field of number theory.] Next, Xu Qingzhou spent a week writing the report, and at the same time rehearsed various questions and challenges he might encounter to ensure that he could handle them with ease at the report meeting. During this period, I started working on my own thesis, titled: The Influence of Spatial Walk-off on the Compression Properties of Quantum Optical Frequency Combs. I have written a quarter of it, and will finish the rest after I return from my business trip. When I was busy with experiments, papers, and writing academic reports, time seemed to be accelerated. March passed quickly and it was March 3th in the blink of an eye. To be more precise, living together with School Beauty Song means that the day of sharing a house with School Beauty Song was postponed until I come back from the business trip. Early in the morning on the 28th, in dormitory 101, Xu Qingzhou packed his things, said goodbye to his three adopted sons in the dormitory, and set off for the airport. After rebirth, this is my first time going abroad. 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 shocked. He was so cool and seemed really busy. He stood there without moving, feeling that just walking away would help something, and planned to continue waiting for news from Song Yao. Sure enough, the message from the other party popped up again: "Be safe and call me when you arrive." 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 a call from Song Yao and was about to look at some information on Cramer's conjecture when he received a call from Professor Gu Zhizhong. "Professor Gu, ok, I know. I'll contact Senior Brother Zhao Zhenglai as soon as I get off the plane." A senior brother named Zhao Zhenglai came to pick him up. From the School of Mathematics of Peking University, the person invited to attend this meeting was Academician Xu Shihui, and Zhao Zhenglai was Academician Xu Shihui's student. 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 School of Mathematics provided sufficient funding, business class, but Xu Qingzhou could only buy an economy class ticket. After finding his seat, he took out the information on the twin prime conjecture from his schoolbag. The proof of the twin prime conjecture went relatively smoothly. We adopted the sieve method + function model and used functions to make up for the shortcomings of the sieve method. 【Selberg noticed that \sum_{d|n}\mu(d)】 [So, when n=1, it is 1, and at other times it is 0. So as long as \lambda_1 is not less than 1, the formula of the sixth step determined by any real number 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 seems to pass through my mind, but I can't grasp it. It's very similar to the feeling described in novels of being in a period of great perfection and about to be promoted. However, Xu Qingzhou's thoughts were quickly interrupted by the chattering of the boy next to him. The sound came from far away, and then a strong smell of perfume came, and there was a rustling sound beside him. A girl sat down next to him, and another young man sat in the aisle. "Xiao Ran, studying abroad for a master's degree is definitely the best choice." While Sun Qingli was speaking, he glanced at the boy who was leaning against the window reading a book. He had been thinking about whether he should exchange seats with Xiao Ran, but when he saw Xiao Ran sitting next to another boy, he felt very unhappy. Moreover, this boy looks a bit handsome. But when he saw that the other party was holding a bunch of messy things in his hands, he suddenly relaxed. He knew that what Xiao Ran hated were those nerds. Yeah, stable. Sun Qingli sat down, his tone full of emotion, "The environment in domestic universities is not good now. All the students educated are nerds. There is no way to compare with those in foreign countries." Hearing this, Xu Qingzhou glanced at him indifferently, shook his head, and shifted his attention to the information in front of him. There were too many people like this, and the moon abroad was always rounder than the moon at home. He was too lazy to argue about it. Seeing that the girl next to him didn't answer, Sun Qingli decided to test the waters, and then he jokingly said, "Why don't you apply to the University of Glasgow? We can take care of each other." Ranna had already become a little impatient, but she still kept a smile on her face and even nodded from time to time. This person is talkative and pretentious. If traveling alone wasn't really boring, she really wouldn't want to go with him. "Georges University has recruited many international students in recent years. With your grades, there will be no problem at all," Sun Qingli continued. Ran Na could only smile perfunctorily: "Let's talk about studying abroad later. This time I came out mainly to relax." "Okay, okay." Sun Qingli nodded with a smile. There was still a week left, so there was no need to rush.
After a while, he looked around and said to himself with some regret: "It's a pity that we bought the tickets in a hurry and they are sold out. Otherwise, we should have bought business class tickets." "It's pretty nice here." Ran Na smiled, took out her iPhone, and prepared to check in and take photos. Xu Qingzhou was still thinking about the twin prime conjecture, automatically blocking out the noise around him, when he suddenly felt someone poking his arm. He turned around and saw the girl lifting the hair beside her ear and looking at him coquettishly, "Handsome, can I change seats with you?" For long journeys like this, Ran Na likes to sit closer to the window where there is more space and she doesn’t have to get 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 do. Not to mention a little brother like him, even a office worker who has been tortured by society for a long time would not refuse the request of such a beautiful sister. As she expected, a warm smile appeared on the boy's face. "No change." "Thanks" The word "thank you" stuck in Ran Na's throat. She looked at the boy in front of her in astonishment, and a voice popped up in her mind: "What are you talking about?" (End of this chapter)
