Lin Feng is not sure how far CERN has gone in detecting dark matter and dark energy.
In other words, CRHPC can't find much information here. It only knows that the other party seems to have made certain breakthroughs in the detection of sterile neutrinos.
However, it is not yet known what specific results the other party has achieved.
CERN has done a good job of keeping this work confidential. Before the official results came out, not much news spread.
Perhaps in the eyes of the current CERN board of directors, the detection results of sterile neutrinos are their bargaining chip to regain the holy land of physics.
But for Xu Chuan, although he was concerned, he really didn't care too much about it.
Dark matter is not so easy to find. Even ordinary neutrinos, such as sterile neutrinos, which are similar to ordinary neutrinos produced by nuclear reactions and radioactive decay of ordinary matter, are not so easy to observe in full.
Strictly speaking, the sterile neutrino he created at CERN actually only observed half of the information about this elementary particle, and maybe even half of the information was missing.
After all, he did not completely study sterile neutrinos in his previous life. There are more types of dark matter than the physics community imagined.
After chatting on the phone for a while about matters at CRHPC, Xu Chuan hung up the phone.
The last important prediction constant of the unified theory of strong electricity is about to be verified, which means that the unified theory of strong electricity will be completely accepted by the physics community.
Of course, the completion of the mining of predicted coupling constants does not mean that it has lost its value.
On the contrary, the true value of the unified theory of strong electricity can only be revealed to the world of physics and academia; now it has officially unveiled itself and shown its true appearance to the world.
The knowledge and truth contained under the veil will guide the development of the physics community for decades or even a century in the future, becoming the most important classic of modern physics.
For Xu Chuan, this is also one of the most magnificent epic achievements among all the research results in his life.
...
Just as he hung up the phone, when Xu Chuan was about to send a message to Zheng Hai, asking him to help book a high-speed rail ticket to Star City, the phone he was still holding vibrated again, and another call came in.
His eyes fell on the name of the caller, a look of surprise flashed in his eyes, and he answered the call.
"Hey, Jiaying, what's wrong?"
The person who called was none other than the youngest student he accepted, Liu Jiaying, and the only undergraduate he accepted.
"Professor, do you have time now?" Liu Jiaying asked with a slightly excited tone on the phone: "My graduation thesis is completed. Should I go find you now, or will you go back to school later?"
Hearing this, Xu Chuan showed a smile on his face and said, "I'll go over."
It just so happened that he hadn't gone to Nanjing University for a while to see how his students were doing and whether they were studying seriously.
"Then I'll wait for you at school?"
Xu Chuan smiled and said, "Well, please send your graduation thesis to my email first, and I'll take a look at it on the way."
"Okay, professor, I'll send it to you right away."
After a brief chat, Xu Chuan hung up the phone and sent a message to Zheng Hai.
It seemed that before going to Star City, he had to go to Nanjing University first.
In the Hongqi car, Xu Chuan used the folding screen mobile phone given to him by Mr. Ren, and downloaded the graduation thesis sent by Liu Jiaying in the mailbox.
"Research on critical points of fixed point number functions based on non-degenerate Hamiltonian diffeomorphisms"
The title of the paper is quite long, but the paper is not very long.
Xu Chuan flipped through it, and judging from the table of contents, there were only fifty-six pages.
Of course, this is not very long compared to regular mathematics journal papers.
For a student, especially an undergraduate, a fifty-six-page paper, even a graduation thesis, is already longer than the average.
Generally speaking, the graduation thesis of ordinary undergraduates and even master's students is usually less than fifty pages. Only the graduation thesis of doctoral students will reach or exceed this number of pages.
Of course, this is mathematics. As for other subjects, he is not sure.
His eyes glanced over the undergraduate thesis of his youngest student. For Xu Chuan, the undergraduate thesis was as easy and simple as a college student solving a primary school student's math problem.
But really, there is a big gap between his student's graduation thesis and the graduation thesis of an ordinary undergraduate.
If we had not known in advance that this was written by Liu Jiaying, it would have been perfectly fine to say that it was a master's degree thesis.
After all, it would be great for ordinary undergraduates to be able to conduct in-depth research on issues in a single field within their own major.
In fact, for most mathematics undergraduates, their graduation thesis usually uses "mathematical tools" to study an "applied experiment", "scientific research project" or "social phenomenon", etc.
After all, use original mathematical tools to study, summarize, and summarize existing phenomena; or create a new summary method through research projects and experimental data...
These are far simpler than going deep into the field of mathematics to dig out the problems hidden in pure mathematics.
Only after reaching graduate school will these students gradually come into contact with knowledge and problems in the truly cutting-edge areas of mathematics.
At this time, their learning goals began to change, and they were no longer just general things learned by the teacher or themselves and stuffed into their brains.
Instead, you selectively select a certain field or direction, and then look for the required knowledge based on the problems that need to be solved.
Liu Jiaying's graduation thesis reached this level.
During her undergraduate career, she had already begun to purposefully choose the direction of her research, and read and acquire the knowledge she needed based on this direction.
This chapter is not over, please click on the next page to continue reading! This graduation thesis is the best summary of her past study career.
Integrate the knowledge in your mind and use it to leverage and solve another unknown problem.
Regardless of whether this paper really solved the problem she encountered, she was already completely different from ordinary undergraduates in terms of her learning style.
Of course, the reason why this happens is actually related to his teaching method.
Whether in his previous life or in this life, he has never taught undergraduate students.
Apart from those open classes to the outside world, the small group teaching model based on teachers and students is all a research-oriented approach.
This teaching method tests students' talents and efforts more, but it can also better guide students' thinking and equip them with the ability to solve problems independently.
However, this teaching method is not without its shortcomings. If his students cannot change their learning model, it will be very difficult for him.
Sometimes I even feel that I have been studying for half a year and have the illusion that I can’t learn anything.
...
NTU, on campus.
After getting off the Hongqi limousine, Xu Chuan quickly walked into his office.
"Professor, you are back."
In the office, Liu Jiaying, who had been waiting here for a long time, saw her tutor and quickly stood up and walked over.
Xu Chuan smiled and nodded, saying: "Let's go in and talk."
As he said that, he took the lead and walked across the student room and assistant room, towards his office at the end.
In the office, even though I haven't been here for a while, it is still spotless and smooth as new. Obviously, someone cleans it every day.
Sitting on the sofa, after taking the printed paper from the hands of the primary school student, Xu Chuan smiled and said: "On your graduation thesis, give me a report first, and I will listen to some of your ideas.
and ideas.”
Although the graduation thesis is already in his hands, he has also read it.
But many times, the paper may not fully express the thoughts and ideas in the author's mind.
This is just like the author of an online article, who constructs a magnificent and wonderful story in his mind, but when it comes to the outline, it becomes no longer perfect, and when he actually writes it, it will probably become a different story.
This is a normal thing (does anyone have a picture, the horse head is perfect, the middle is average, and the horse tail is abstract, I can't find it ~ QAQ).
Liu Jiaying nodded and began to report on his graduation thesis.
On the sofa, Xu Chuan nodded in agreement while listening to her report.
Except for some nervousness and worries about whether her graduation thesis will pass the test, it is not difficult to see her familiarity and understanding of her graduation thesis.
A report of ten minutes is enough for a graduation thesis.
After giving a complete explanation of his graduation thesis, Liu Jiaying looked at Xu Chuan nervously, with anxiety in his eyes.
After all, this is related to whether you can graduate successfully.
Holding the paper in his hand, Xu Chuan smiled and said: "It's a very good paper. You have gone very deep into the study of diffeomorphisms and topological invariants."
"but....."
After a slight pause, he stood up and walked towards the corner. While dragging out a blackboard from the corner, he continued: "There are still some small problems in this, or areas that can be optimized."
He picked up a white marker from the pen basket hanging next to him. After removing the cap of the pen, Xu Chuan thought about it and wrote on the blackboard:
"For example, on page seven, you used the traditional smooth Newton method to study the non-negative quadrant weight complementarity problem. It is undeniable that it is indeed the most commonly used method to solve complementarity problems. You are also very smart.
Push it forward into the study of non-negative quadrant weight complementarity issues."
"However, under appropriate assumptions, given the weight vector w ≥ 0, a new smooth function Φ(μ, a, b) of formula (1) can be constructed: RxRxR→R..."
".....Choose constants δ, σ∈( 0, 1), ξ~>0. Select the positive sequence {ξ k } and satisfy ∞∑k =0ξ k≤ξ~
