The next day, it arrived as expected.
The news that Li Mu is going to hold an open class at St. Petersburg State University has already spread, and the report he gave is based on the existence and smoothness of the solution to the NS equation that he just proved not long ago, and then goes into more details. A little explanation.
Such an open class naturally attracted the attention of other mathematicians.
Basically, these mathematicians have participated in the International Congress of Mathematicians, but have not returned yet and are still staying here. After all, strictly speaking, July is still during the summer vacation. For those mathematics professors who teach in universities, it is also I'm not so anxious to return.
As a result, what surprises them now is that they did not expect to have such benefits if they stayed.
Although Li Mu's report was detailed enough, if there were more details, they would naturally be quite happy.
As a result, Li Mu's open class attracted a large number of mathematicians to participate.
As an open class, this class was not held in any classroom, but in the auditorium of St. Petersburg State University.
As a country that generally believes in Orthodox Christianity, this luxurious auditorium also has a very religious style. Of course, it is also very luxurious.
And even for the students here, every time they come to the auditorium, it gives them a different feeling.
"It's hard to believe that Li Mu's open class was actually held in the auditorium. It's incredible that the school is willing to open the auditorium for him!"
Students from the Department of Mathematics of St. Petersburg State University had almost arrived at the seats in the auditorium. They could not help but marvel at the grand scene in the auditorium.
"Of course. After all, that is Professor Li Mu. He solved the most difficult mathematical problem in the NS equation. We are lucky that he is willing to come to our school to hold an open class."
Some students couldn't help but say at this time: "But, will we really understand it then? I have only studied a little bit about fluid mechanics."
"Hey, it doesn't matter whether you understand or not. The main reason is to meet Professor Li with my own eyes." Another student shrugged his shoulders and said indifferently: "I haven't even studied fluid mechanics. , this is an elective course, I haven’t studied it at all.”
When their school promoted this open class, they also allowed students from their mathematics and physics departments to sign up at will. They did not select a certain class. Anyway, there were enough seats in the auditorium.
So they all signed up regardless of whether they understood it or not. After all, this is the only truly amazing class in mathematics in this era.
"I heard that many other well-known mathematicians will come today, but I don't know which ones will come."
A student looked at the entrance of the auditorium and said curiously, and suddenly at this moment, he exclaimed: "What did I see? Is that...Professor Perelman?"
His words immediately attracted the attention of other students around him. For a moment, their eyes were directed to the entrance, and then their eyes widened.
That iconic beard, and that face...
Students of mathematics at St. Petersburg State University are simply too familiar with it.
This was their former senior, the pride of their school, and the first certifier of the seven millennium problems. Even Li Mu was the second one. Of course, considering Li Mu's age, this was indisputable. Avoidable, after all, Li Mu was only two or three years old when Perelman proved the Poincaré conjecture.
However, although Perelman's entry brought an uproar and surprise to the people present at first, they quickly remembered Perelman's temper, so they tried their best not to go there. Pay attention to him so as not to offend him.
This is the most important thing for Perelman. He was invited by Li Mu and also came for his further explanation of the NS equation. Although he was ready to be watched by everyone, he was gratified. It's just that his coming over didn't attract too many eyes.
What he doesn't like is the feeling of being talked about by too many people, and he just hopes that he can become one of the common people.
Bolonnikov saw his old friend returning to his homeland again, although even in normal times, the distance between this homeland and Perelman was only about ten kilometers.
With his eyes a little red, Bolonikov went up and punched him: "I told you to come back and you didn't come back. Li Mu asked you to come back, and you came back?"
Perelman also smiled when he saw his old friend, and then said: "If you could prove the existence and smoothness of the solution to the NS equation, then I would have been back long ago."
Bolonnikov was silent for a moment, and then said angrily: "Just say you don't want to come back. To prove this problem...how much do you think highly of me?"
They both laughed.
Later, Bolonnikov also took Perelman to sit in the first row.
Most of the people sitting in the first row were old acquaintances of Perelman, and they all said hello to him and welcomed him back.
However, people also had a tacit understanding not to talk about him too much.
In this way, time passed quickly until finally, the time for the open class officially began.
Li Mu also walked out of the backstage lounge. Looking at the auditorium that was almost full of people, he sighed with emotion. Although Russia is vast and sparsely populated, there are not a lot of students studying mathematics.
Of course, the audience also included physics majors. After all, NS equations and fluid mechanics are indeed things in classical physics, although the mathematics department will also conduct specialized research on this issue.
Shaking his head and thinking no more, he then said: "I am honored to be invited by St. Petersburg State University to come here to give a public class."
"St. Petersburg State University is a university with a very long history. From here came many famous people who I once admired, such as Leonhard Euler, the 18th-century mathematics master, and for all our modern mathematicians. It is said that Euler is the same figure as the ancestor."
"Another example is Mr. Chebyshev, who also made a huge contribution to our mathematics."
"Including the current president of Russia, he also came out of here - the president is also a very charming person."
"So, I also believe that every student here has the same great potential."
"Then, I also hope that my next course can add a boost to your journey towards greatness." Li Mu smiled slightly: "Let's start this class from now on."
Since you are invited to give a speech at someone else's school, the first thing that is inevitable is to brag about your business.
After he finished bragging, he turned around and walked to a small blackboard that was pushed up, and this open class officially began.
Since the theme of his class is related to the existence and smoothness of the solution to the NS equation that he proved, the content of the class will naturally focus on this aspect.
However, there are two groups that his class serves. One group is the vast majority of students in the auditorium. They are the main service targets of this class. Apart from them, , and the other group is the mathematicians who came after hearing the news, such as Perelman.
Perelman was invited by Li Mu, and they came because they heard that what he was going to talk about was related to the NS equation.
And if the content he talks about is only at the student level, then it is obviously not good.
So how can we make students think and mathematicians increase their understanding at the same time?
This is full of difficulties.
But for Li Mu, challenging the difficulty is what is interesting.
As the class began, Li Mu also fully demonstrated his high ability in teaching.
All the students present did not even need to study fluid mechanics. As long as they had an understanding of partial differential equations, they could understand the NS equation through his explanation and gradually understand Li Mu's proof.
Solving partial differential equations is itself a research direction of partial differential equations, and proving the existence of solutions to partial differential equations is also a research direction.
For them, Li Mu's class can be regarded as a class on partial differential equations, and during the process, it can also make them think about why Professor Li has to do this at this step and handle it like that at that step.
As for mathematicians like Perelman and Li Mu, in this class, the steps to guide students to think are, for them, knowledge that can deepen their understanding of Li Mu's proof process.
Therefore, it can be said that Li Mu’s public class successfully took care of both groups at the same time.
Until the end of this class an hour later.
"Then, the content of this open class is the above."
"I hope everyone here can gain something."
Behind him was a small blackboard filled with various styles. Li Mu stood at the front of the podium, facing everyone, and then bowed slightly.
Everyone present suddenly woke up from a dream, and then warm applause rang out in the entire auditorium.
"It's actually over!"
Dean Bolonnikov's face showed surprise, "Why do I feel like it's only been half an hour?"
Next to him, Cherobavsky, the dean of the School of Physics, sighed with emotion: "I really didn't expect that Professor Li is not only extremely talented in academics, but he is even so good in class."
"Yeah, what he said sounds very inspiring to me, and he also has some things that are very suitable for undergraduates and graduate students... He is really a magical person." On the other side, their mathematics professor also said the same said.
Everyone was amazed.
An excellent scholar is often not necessarily an excellent teacher.
Although the vast majority of scholars hold the position of teachers and professors and give lectures to students, this does not mean that they are good enough at giving lectures.
Therefore, there is a difference between a great educator and a great scholar.
Now it seems that Li Mu is not only a great scholar, but also has the potential to become a great educator.
This makes Bolonnikov and others, who are also scholars and educators, feel very envious.
"Perelman, what do you think? You don't regret coming to this class, do you?" Bolonnikov also turned to Perelman at this time and asked.
Perelman lowered his head and pondered for a long time. Until finally, he raised his head and nodded, "Yes, this is a very exciting course."
…
Li Mu's open class has ended, and the video of the entire open class has been completely posted on the Internet.
Once the video was released, it attracted thousands or even nearly 10,000 downloads.
People who downloaded this open course are also divided into several groups.
The first group is mathematicians from all over the world, especially those who study partial differential equations and Navier-Stokes equations. Many of them participated in the International Congress of Mathematicians and then For those mathematicians who left St. Petersburg before the start of Li Mu's open class, although they missed the scene, this video was naturally impossible to miss.
The second group is naturally the students. After all, the students of St. Petersburg State University all said yes after listening to the class. For those students who are interested and more motivated, they are naturally more unwilling to miss it.
In addition to these two groups, there is a third group, that is, the professors. They want to learn from Li Mu how to teach. Especially Li Mu’s open class, not only can students gain a lot of Full, even the mathematics scholars present are like this. For their teachers, this is certainly worth learning.
But unfortunately, after watching Li Mu's complete video, they had no choice but to give up, because such a class requires a mathematical ability like Li Mu's to support it. Without his mathematical ability, the complex can be simplified. With such effort, it is completely impossible to achieve his effect.
In a word, those who learn from me will live, and those who resemble me will die.
That's it.
…
"you are leaving?"
"Yeah, it's time to go."
At the door of the hotel, Li Mu, who was leaving St. Petersburg today, received everyone's farewells.
The people who came to see him off were basically people from St. Petersburg State University.
Bolonnikov said helplessly: "Although I know it is probably impossible, I still want to say that you are always welcome to join St. Petersburg State University."
Li Mu smiled and said, "Thank you."
"Of course, although you can't officially join now, I think you won't refuse the position of tenured honorary professor, right?"
Suddenly, Bolonnikov took another letter of appointment from the side, which was about St. Petersburg State University appointing him as a lifelong honorary professor of the school.
Li Mu was stunned for a moment, then immediately laughed: "Of course, this is also my honor."
"That's great!" Bolonikov smiled and nodded, and then handed the letter of appointment to Li Mu.
Of course, having someone take a photo of them together is indispensable.
"Well, I wish you a safe journey."
After the group photo was completed, Bolognikov solemnly shook hands with Li Mu and sent his final blessings.
"Oh, by the way, Perelman didn't come today, but he asked me to say goodbye to you and give you good news. After watching your open class, he became interested in class again, like As before, he is also very enthusiastic about helping his classmates and friends learn mathematics."
"Even I had help from him."
Bolonnikov smiled: "So, he has planned to return to school occasionally to teach the students."
Hearing the news, Li Mu smiled sincerely: "This is great news for the mathematics community."
…
Perelman was willing to start classes again, probably because his return to school did not receive too much attention this time, so he no longer felt awkward.
After all, no matter what, he still likes to discuss mathematics with others and share his results with others. Just like when he once put his proof of the Poincaré conjecture on a website, he also took the initiative to give it to a dozen mathematicians he knew. The experts sent emails, asking them to take a look at the paper he sent.
So, this is certainly good news for the mathematics community.
On the other hand, there is also good news for patients with blood clots.
When Li Mu's plane landed at Oxford Airport, he received a call from China.
Kingsley Ware, brought him great news.
"Boss! Our RSCA anti-thrombotic drug has passed the third phase of clinical trials!"
