Chapter 178 Goldbach's conjecture? In the restaurant, the old academician did not stay long. He told Zhao Zhenglai to take good care of Xu Qingzhou and left in a hurry. Xu Qingzhou looked at Academician Xu Shihui's back and smacked his lips: "Is Academician Xu always so busy?" "The teacher just can't rest." Zhao Zhenglai smiled and sighed: "In my impression, the teacher only sleeps five hours a day and spends almost all his energy on mathematics." Xu Qingzhou also had some admiration. The older generation of scientific researchers had worked countless times harder than them. In that era, there were no large computers to provide computing power support, and all projects were basically calculated bit by bit by manpower. Zhao Zhenglai retracted his gaze, and while chewing his sandwich, he asked with a smile: "Junior brother, how did you sleep last night?" "Not bad." Xu Qingzhou nodded and slept until dawn, but because of the jet lag, he still had a light feeling of sudden death. "It's a pity that you didn't come. There were several beautiful girls there last night." Zhao Zhenglai looked nostalgic. Only then did Xu Qingzhou notice that there were many red marks on Senior Brother Zhao's neck, which showed how intense the fun was last night. Tsk tsk, luckily I didn’t go.
With emotion, he reminded himself to be careful in the next few days. If he got a mark on it, he would be doomed when he returned. After they finished their breakfast, they headed towards the lecture hall. Walking on the campus of Cambridge, you can clearly feel the academic atmosphere that is different from that of Xiaguo, especially the students passing by, giving people a sense of ease and vitality. Xu Qingzhou had worked as a lecturer both in China and abroad. He discovered a pattern: at the undergraduate level, students from the Xia country were not actually at a disadvantage. On the contrary, they had a solid foundation of knowledge and mastered a lot. But when it comes to graduate school, Xia Guo’s students will find it difficult because this period usually requires a flexible way of thinking, which is precisely their shortcoming. This does not mean that Xiaguo’s students are incapable, but that it takes some time to change the inertial thinking brought about by the exam-oriented education. In comparison, the university system of Cambridge is more flexible and diverse, and pays special attention to the personalized development and innovative ability cultivation of students. The country has also made progress in recent years, such as the undergraduate research system of the School of Mathematics at Peking University, the "SRT Program" established by Shuimu University, and other universities are also introducing various plans to mobilize students' enthusiasm. As Zhao Zhenglai walked, he asked, "Junior brother, now that you have figured out Cramer's theorem, are you ready to start new research?" Xu Qingzhou said: "I am working on the twin prime conjecture." "Hiss~ Are you studying the twin prime conjecture?" Zhao Zhenglai looked at Xu Qingzhou in surprise. Xu Qingzhou smiled and said, "Yes, let's try something more difficult." This is not just difficult, it's hell! Zhao Zhenglai had a complicated expression on his face. After a long while, he uttered two words: "Awesome!" You're only a freshman, do you have to be so unbelievable? "How's the progress?" Zhao Zhenglai was a little curious again. Although this junior brother was awesome and proved Cramer's theorem, it didn't mean he could do anything. After all, many achievements really came out of a flash of inspiration. Xu Qingzhou said helplessly: "It's difficult. Now I'm stuck." "Normal." Zhao Zhenglai was not surprised. There are so many great people studying this, such as the Chinese mathematician Terence Tao, who won the Fields Medal, and Andrew Wiles, who proved Fermat's Last Theorem. Unfortunately, no one succeeded. He said, "The speaker this morning is Benji Dart, a mathematician from Switzerland. His talk is about the analytical extension of Dirichlet's L function. You should listen carefully. It may help you in your research." "I am also prepared to listen carefully." Xu Qingzhou was a little looking forward to it. The process of proving the twin prime conjecture did involve the L function, which was mainly used to improve and supplement the sieve method.
The two walked for about 15 minutes. Zhao Zhenglai pointed to the old building in front and said, "The lecture will be held in the building in front." Xu Qingzhou nodded. In the past, he always held his lectures in another auditorium. This side, um, it seems like he hasn’t really come here. Last night he logged into the official website and looked carefully. In 7 days, there were 2 special invited reports at the conference, both scheduled in the last two days, and 19 other invited reports, and his was one of them. In addition, there are also various small seminars and special exchanges. The two signed in at the door and then walked towards the hall. As soon as they entered the hall, Zhao Zhenglai left in a hurry to find Academician Xu, while Xu Qingzhou planned to take a look around on his own first. It’s quite lively, a bit like visiting a night market. In addition to these specially invited people, there were also many scholars who came here because of its reputation. As long as you are attending the conference, you can display your results on the blackboard in an empty classroom, corridor or hall. In order to attract others, many scholars directly pull out promotional posters. There were four or five people who were studying the theory of divisibility and congruence, gathered in front of the blackboard, talking at once. The person in charge of this project was a middle-aged Russian man, who was explaining it to the people around him in slightly broken English. While speaking, he occasionally wrote a few lines of formulas on the blackboard. Since it was the first day, many scholars were still preparing blackboards and hanging posters. Xu Qingzhou was not in a hurry. He went to the service desk to get a cup of coffee, sat on the balcony to enjoy the breeze, and checked messages on his mobile phone. There is not much news on WeChat. The experiments in the laboratory have been temporarily suspended. The only thing left is the testing of the last crystal, which will be continued after he returns. Song Yao and Guo Ziyang were chatting alone, while Xu Zhengyang and others were asking about the situation in the group. He simply replied to the messages from Xu Zhengyang and the other two, then opened the chat box with Song Yao. Their conversation stopped when he got up. Song Yao said that she had just finished class and was going to the library to read. Xu Qingzhou glanced at the message and then exited, drinking his coffee while scrolling through his photo album. Wow, when were there so many photos of Song Yao? Looking at the more than 200 beautiful photos in the album, Xu Qingzhou himself was surprised. He recalled his acquaintance with Song Yao in his mind and wondered when he started to be attracted to her. Until he finished his coffee, he still couldn't figure out whether he was attracted by the girl's beauty, love at first sight, or love that grew over time, so he got up and prepared to go shopping again. There are more people than before, and it is getting more lively. In one of the large classrooms, Xu Qingzhou saw Academician Xu and his colleagues. The screen at the front of the classroom was demonstrating the structural diagram of a complex system, and everyone was concentrating. Other people who entered were also very cautious, fearing that the noise they made would disturb those who were thinking. Xu Qingzhou smiled lightly and had no intention of going in. This was not his area of research. He wandered around for a while and entered a large classroom. It's very lively here, with several groups of people, all carrying on their own discussions without interfering with each other. Xu Qingzhou was stunned when he saw the words "Proof of Goldbach's Conjecture" on a poster next to the blackboard. Holy shit, so awesome? (End of this chapter)
