Great Country Academician

Lin Feng is not sure about the specific progress of CERN's detection of dark matter and dark energy.

Or CRHPC cannot get much information, only knowing that the other party seems to have made some breakthroughs in the detection of sterile neutrinos.

However, it is not 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 was circulated.

Perhaps in the eyes of the current CERN board of directors, the detection results of sterile neutrinos are their bargaining chips to regain the holy land of physics.

However, for Xu Chuan, although he is concerned, he really doesn't care too much about this matter.

Dark matter is not so easy to find. Even 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 neutrinos he made at CERN actually only observed half of the information of this elementary particle, or even half of it.

After all, he had not thoroughly studied the inert neutrinos in his previous life, and there are more types of dark matter than the physics community imagined.

On the phone, after chatting about CRHPC for a while, Xu Chuan hung up.

The last important predicted constant of the strong-electric unified theory is about to be verified, which means that the strong-electric unified theory will also be completely accepted by the physics community.

Of course, the completion of the excavation of the predicted coupling constant does not mean that it has lost its value.

On the contrary, the true value of the strong-electric unified theory has just begun to unfold to the physics community and the academic community; now it has officially unveiled its veil and shown its true face 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, and become the most important classic of modern physics.

For Xu Chuan, this is also one of the most magnificent and epic achievements of all his research results in his life.

Just after hanging up the phone, when Xu Chuan was about to send a message to Zheng Hai to ask him to help book a high-speed rail ticket to Xingcheng, the mobile phone he was holding vibrated again, and another call came in.

His eyes fell on the name of the caller, and a look of surprise flashed in his eyes, and he answered the call.

"Hello, Jiaying, what's wrong?"

The caller was not someone else, but the youngest student he accepted, Liu Jiaying, who was also 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 come to see you now, or will you return to school later?"

Hearing this, Xu Chuan smiled and said, "I'll go."

It just so happened that he hadn't been to Nanjing University for a while to see how his group of students were doing and whether they were studying seriously.

"Then I'll wait for you at school?"

Xu Chuan smiled and said, "Well, send your graduation thesis to my email first, and I'll take a look 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 seems that before going to Xingcheng, he has to go to Nanjing University first.

In the Red Flag sedan, using the folding screen mobile phone that Mr. Ren gave him, Xu Chuan downloaded the graduation thesis sent by Liu Jiaying from his mailbox.

"Research on the Critical Points of the Fixed Point Number Function Based on Non-degenerate Hamiltonian Differential Homeomorphism"

The title of the thesis is quite long, but the thesis is not very long.

Xu Chuan flipped through it and saw from the table of contents that it was only fifty-six pages.

Of course, this is not very long compared to regular mathematical journal papers.

For a student, especially an undergraduate, a fifty-six-page thesis, even a graduation thesis, is already beyond 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 very clear.

His eyes glanced over the undergraduate graduation thesis of his youngest student. For Xu Chuan, the undergraduate graduation thesis is as easy and simple as a college student solving a primary school student's math problem.

But to be honest, there is still a big gap between his graduation thesis and that of ordinary undergraduates.

If we didn't know in advance that it was written by Liu Jiaying, it would be fine to say that it was a graduation thesis of a master's student.

After all, it is already very good for ordinary undergraduates to be able to study problems in a single field in depth within their major.

In fact, for most mathematics undergraduates, their graduation thesis usually uses "mathematical tools" to study a certain "applied experiment", "scientific research project" or "social phenomenon", etc.

After all, using the original mathematical tools to study, summarize and conclude existing phenomena; or creating 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, these students will gradually come into contact with the knowledge and problems in the real frontier fields of mathematics.

At this time, their learning goals began to change. They no longer simply stuffed everything they learned from their teachers or themselves into their brains.

Instead, they selectively chose a certain field or direction, and then looked for the knowledge they needed based on the problems they needed to solve.

Liu Jiaying's graduation thesis reached this level.

In her undergraduate career, she had already begun to purposefully choose the direction of her research, and read and absorb the knowledge she needed based on this direction.

This graduation thesis is the best summary of her past learning career.

It is about integrating the knowledge in her mind and using it to pry and solve another unknown problem.

Regardless of whether this thesis really solved the problem she encountered, she is completely different from ordinary undergraduates in terms of learning methods alone.

Of course, the reason for this situation is actually related to his teaching method.

Whether in his previous life or this life, he has never taught undergraduates.

Apart from those open classes for the outside world, the small group teaching model based on teachers and students is a research-based approach.

This teaching method tests students' talents and efforts, but it can also better guide students' thinking and enable them to solve problems independently.

However, this teaching method is not without disadvantages. If his students cannot change their learning mode, they will have a hard time under him.

Sometimes I even feel that I have learned for half a year or a year, but I have the "illusion" that I can't learn anything.

Nanjing University, campus.

After getting off the Red Flag car, Xu Chuan walked into his office quickly.

"Professor, you are back."

In the office, Liu Jiaying, who had been waiting here for a long time, stood up and walked over after seeing his tutor.

Xu Chuan smiled and nodded, saying, "Let's talk inside."

As he said, he took the lead and crossed the student room and the assistant room, and walked towards his office at the back.

In the office, although it has been a while since I came, it is still spotless and clean. Obviously, someone cleans it every day.

Sitting on the sofa, after receiving the already printed paper from the elementary school student, Xu Chuan smiled and said, "Give me a report on your graduation thesis first, and I want to hear some of your ideas and thoughts."

Although the graduation thesis is already in his hands and he has read it.

But many times, the thesis may not fully express the author's ideas and thoughts.

This is just like the author of an online article. He constructs a magnificent and wonderful story in his mind, but when it comes to the outline, it is no longer perfect, and when he really writes it, it will probably become a mess.

This is a very normal thing (who has a picture of a horse head that 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 her graduation thesis.

On the sofa, Xu Chuan listened to her report and nodded in agreement.

In addition to some nervousness and worry about whether her graduation thesis can pass, it is not difficult to see that she is familiar with and understands her graduation thesis.

A dozen minutes of report time is enough for a graduation thesis.

After giving a complete explanation of his graduation thesis, Liu Jiaying looked at Xu Chuan nervously, with trepidation in his eyes.

After all, this was related to whether he could graduate successfully.

Holding the paper in his hand, Xu Chuan smiled and said, "It's a very good paper. You have done a very in-depth study on differential homeomorphisms and topological invariants."

"But."

After a slight pause, he stood up and walked towards the corner, dragging out a blackboard from the corner, and continued, "There are still some small problems, or areas that can be optimized."

He picked up a white marker from the pen holder hanging next to him, uncapped it, thought for a while, and wrote on the blackboard:

"For example, on page 7, you used the traditional smooth Newton method in your study of the complementary problem of non-negative quadrant weights. It is undeniable that it is indeed the most commonly used method for solving complementary problems, and you are also very smart to promote it to the study of the complementary problem of non-negative quadrant weights."

"But under appropriate assumptions, we can give a weight vector ω≥ 0 and construct a new smooth function Φ(μ, a, b) of formula (1): R×R×R→R"

". Select constants δ, σ∈(0, 1), ξ~\u003e0. Select the positive sequence {ξ k } and satisfy ∞∑k =0ξ k≤ξ~\u003c∞. Let the initial point be”

In the office, Xu Chuan explained while writing a few lines of mathematical formulas on the blackboard, then looked at Liu Jiaying and asked with a smile.

“What is this, do you see it?”
