Chapter 178 Goldbach’s conjecture?
In the restaurant, the old academician did not stay long, told Zhao Zhenglai to take good care of Xu Qingzhou, and left in a hurry.
Xu Qingzhou looked at the back of Academician Xu Shihui and clicked his tongue: "Is Academician Xu always so busy?"
"The teacher just can't take any time off." 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 was also a little impressed. The older generation of scientific researchers worked many times harder than them. At that time, there were no large computers to provide computing power support, and all projects basically relied on manual calculations.
Zhao Zhenglai looked away, and while chewing a sandwich, he asked with a smile: "Junior brother, how did you sleep last night?"
"It's not bad." Xu Qingzhou nodded and slept until dawn, but because of the jet lag, he still felt like he was dying suddenly.
"It's a pity that you didn't come. There were several beautiful girls last night." Zhao Zhenglai said with an afterthought expression.
Only then did Xu Qingzhou notice that Senior Brother Zhao had a lot of red marks on his neck. You can imagine how hard he played last night.
Tsk tsk, luckily I didn’t go.
In the midst of emotion, he warned himself to be careful in the next few days. If a mark was found, he would be doomed when he returned.
The two of them finished their breakfast and headed towards the lecture hall.
Walking on the Cambridge campus, you can clearly feel the academic atmosphere that is different from Xia Guo, especially the students passing by, giving people a sense of ease and vitality.
Xu Qingzhou once served as a lecturer at home and abroad. He discovered a pattern. At the undergraduate level, Xia Guo's students were not at a disadvantage. On the contrary, they had solid basic knowledge and mastered many things.
But when it comes to the postgraduate stage, Xia Guo's students will have a harder time, because this period usually requires a flexible thinking model, which is exactly their shortcoming.
This is not to say that Xia Guo’s students are not good, but it takes a certain amount of time to change the inertial thinking brought about by exam-oriented education.
In comparison, the system of colleges and universities like Cambridge is more flexible and diverse, and pays special attention to the individual development and innovation ability of students.
The country has also made progress in recent years, such as the undergraduate scientific research system of Beijing University's School of Mathematics, the "SRT Plan" established by Shuimu, and other universities are also launching various plans to mobilize students' enthusiasm.
Zhao Zhenglai asked as he walked: "Junior brother, you have mastered Kramer's theorem, are you ready to start new research?"
Xu Qingzhou said: "We are working on the twin prime number conjecture."
"Hiss~ Are you studying the twin prime conjecture?" Zhao Zhenglai looked at Xu Qingzhou in astonishment.
Xu Qingzhou smiled: "Yes, let's challenge the difficulty."
This is not only extremely difficult, it is simply hell!
Zhao Zhenglai looked complicated, and after a long time, he uttered two words: "Awesome!"
You are only a freshman, do you want to be so unfaithful?
"How's the progress?" Zhao Zhenglai was a little curious again. Although this junior fellow student is awesome and proved Kramer's theorem, it doesn't mean that it will be possible. After all, many achievements really come from a flash of inspiration.
Xu Qingzhou said helplessly: "It's quite difficult, now I'm stuck."
"Normal." Zhao Zhenglai was not surprised. There are too many great people studying this thing, such as Chinese mathematician Terence Teru, winner of the Fields Medal, and Andrew Wiles, who proved Fermat's Last Theorem
It's a pity , and no one succeeded.
He said: "The lecturer this morning is the mathematician Benji Dart from Switzerland. The content is about the analytical extension of the Dirichlet L function. You can listen to it carefully. It may be helpful to your research."
"I'm also going to listen carefully." Xu Qingzhou looked forward to it. The process of proving the twin prime conjecture indeed involves the L function, which is mainly used to improve and supplement the sieve method.
The two walked for about 15 minutes. Zhao Zhenglai pointed to the ancient building in front: "The report meeting will be arranged in front of the building."
Xu Qingzhou nodded. He used to hold reporting meetings in another auditorium.
Well, it seems like we haven't come here yet.
Last night he logged on to the official website and took a closer look. In seven days, there were two special invitation reports for the conference, both scheduled in the last two days. There were also 19 invited reports, and his was one of them.
In addition, there are also various small seminars and special exchange meetings.
The two signed in at the door and then walked towards the hall.
As soon as he entered the hall, Zhao Zhenglai left in a hurry to find Academician Xu, while Xu Qingzhou planned to take a look around first.
It's quite lively, a bit like visiting a night market.
In addition to these specially invited people, there are also many scholars who come here with admiration.
Anyone who attends the conference can freely display the results on the blackboard in unmanned classrooms, corridors, and halls. In order to attract other people, many scholars directly pull out promotional posters.
There was someone studying the theory of divisibility and congruence. Four or five people gathered in front of the blackboard, chatting away. The person in charge of this topic was a middle-aged Russian who was explaining to the people around him in somewhat broken English.
While talking, he wrote a few lines of formulas on the blackboard from time to time.
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 order a cup of coffee, and sat on the balcony to enjoy the breeze while reading messages on his mobile phone.
There are not many messages on WeChat. The experiments in the laboratory have been temporarily suspended. The last 2.0mm crystal is left to be tested and will be continued after he returns.
Song Yao and Guo Ziyang were chatting individually, while Xu Zhengyang and the others were asking about the situation in the group. He simply replied to Xu Zhengyang's message and opened the chat box with Song Yao.
The chat between the two stopped when he got up. Song Yao said that he had just finished class and was going to the library to read.
Xu Qingzhou glanced at the message twice, then exited, sipping coffee and drawing out the photo album.
Hey, when did we have so many photos of Song Yao?
Looking at the more than 200 beautiful photos in the album, Xu Qingzhou felt surprised. He thought about his relationship with Song Yao and thought about when he started to be greedy and fell in love with her.
Until he finished the coffee. , he didn't even figure out whether he was interested in her, fell in love at first sight, or fell in love over time, so he got up and prepared to go shopping again.
There were more people than before and it was getting more lively.
In one of the large classrooms, Xu Qingzhou saw Academician Xu and the others. The screen in front of the classroom was demonstrating the structure diagram of a complex system, and everyone was engrossed in it.
Others who entered were also cautious, fearing that they would disturb those who were thinking by making noise.
Xu Qingzhou smiled softly and had no intention of going in. This was not his field of research.
He wandered for a while and entered a large classroom.
It's very lively here, with several groups of people, and everyone is having their own discussions without interfering with each other.
Xu Qingzhou was stunned when he looked at the words "Proof of Goldbach's conjecture" on one of the posters next to the blackboard.
Holy shit, so awesome?
