As the bell rang, Li Mu's first class in his life ended.
Judging from the effectiveness of the teaching, using an unsolved problem to gradually lead students to become interested in number theory, this class can be regarded as a success.
At least, throughout the whole class, all the mathematics students were attracted by Li Mu's narration.
Even students from other majors, such as those majoring in physics, can listen as long as they have a certain foundation in mathematics.
Of course, the most fundamental reason is that the content Li Mu taught in this class is not particularly difficult. It is just the basic part of undergraduate number theory. In addition, these students present are all top students, so they absorb knowledge. The speed is also very fast.
As the class ended, nearly half of the students present did not leave, but continued to stay in the classroom, discussing with each other and thinking about the problems just now.
Of course, the students gained something, and as a teacher, Li Mu also gained something from this class.
Sitting in front of the podium, he took out his scratch paper and began to make calculations based on the inspiration that suddenly came to him in class.
"Boltzmann's equation..."
As a classic equation in statistical physics, the Boltzmann equation does not statistically analyze the position and momentum of each particle in the fluid, but only considers a group of particles occupying any small area in space at the same time and centered on the end of the position vector. particle.
In other words, the scope of its consideration should be more general.
From a certain point of view, this is also in line with Li Mu's needs, because it is very consistent with his Li Space.
However, it is not enough to have good fit. It must also be able to help Li Mu solve the Navier-Stokes equation, a partial differential equation problem.
"If you start from the direction of number theory..."
Li Mu narrowed his eyes slightly.
The computer in his mind began to work crazily, helping him to make deductions while also helping him find various possible inspirations.
And soon, he had a direction. In fact, during the class just now, he had a new idea.
The corners of his mouth curled up slightly, and the pen tip began to move.
"The biggest advantage of the Boltzmann equation is that it does not consider the situation of a single particle, but the biggest disadvantage also lies here. As a result, the things it considers are relatively not detailed enough."
“And if we can take advantage of its overall advantages and make up for its shortcomings in details, then this equation can become more complete.”
"So, next, I just need to..."
It took almost no time, just a little while, and a piece of draft paper was filled with formulas.
In this way, his calculations gradually entered the state.
And just as he was calculating, Wiles and the others who had just finished watching the entire class came up.
They all had exclamations on their faces, feeling incredible because this was Li Mu's first class since becoming a teacher.
This is not like the first class of a new teacher, it is completely like a veteran.
How can anyone start showing off their skills in the first class?
"Li Mu, you said you don't know how to go to class!"
After walking forward, Li Hete couldn't help but say something.
However, Li Mu did not raise his head and continued the calculation in his hand.
Li Heter thought Li Mu hadn't heard. Just when he was about to shout again, Wiles suddenly reached out to stop him and said, "Shh, don't talk yet. Li Mu... seems to be thinking about other key issues now."
Several professors were stunned.
Li Mu, what problem are you studying again?
They walked forward quietly and stood behind Li Mu to take a look.
"Hmm...this seems to be physics?" another professor asked.
"Mathematical physics, as we all know, Li Mu is also a top theoretical physicist." Richter said with a smile.
However, compared to their discussion, Wiles's brows furrowed.
"Wait a minute, Li Mu seems to be studying... fluid mechanics?"
"Fluid mechanics?"
Several people were stunned.
Anyone who studies mathematics, of course, knows what fluid mechanics is. After all, after switching from mathematics to physics, quite a few people began to study fluid mechanics, including Terence Teru, who also studied fluid mechanics.
In some ways, the study of fluid mechanics can now be regarded as a completely mathematical problem.
The ultimate goal of all mathematical scholars who study this aspect is to impact the Navier-Stokes equation, the ultimate problem of classical physics.
Therefore, almost immediately, they guessed that Li Mu was trying to solve this problem!
Li Heter was suddenly startled, and he remembered something.
"In July, the International Congress of Mathematicians is coming, and Li Mu is one of the speakers at the plenary meeting. Could it be..."
His eyes showed surprise: "Is this his purpose?"
Everyone was stunned, and immediately looked at Li Mu in disbelief.
Li Mu, plans to attack the Navier-Stokes equation before the International Congress of Mathematicians?
Just as they were marveling, Li Mu's hand that was constantly calculating on the draft paper suddenly stopped at this moment, and his brows frowned slightly.
After a moment, he shook his head, then put away the pen and put the cap back on.
After raising his head, he finally noticed the professors surrounding him.
He was stunned for a moment, then smiled: "Professor Wiles, Professor Richter, and Professor David... I didn't expect you to come to my class."
Wiles smiled and said: "After all, this is the first class in your life as a teacher. As your former teacher, of course I have to come and take a look."
Li Hete, who was next to him, immediately rolled his eyes and exposed him: "You obviously came here because of the news about queuing for class. Before you came, you were surprised that Li Mu actually started class today."
Everyone laughed.
Wiles waved his hand indifferently and said, "Don't worry about these details."
Then, he looked at Li Mu again.
"You're... studying fluid mechanics? Is it the Navier-Stokes equation? That question of the millennium?"
As Wiles asked the question, everyone else stopped talking and turned to look at Li Mu, waiting for his answer.
Li Mu did not hide it. After nodding, he said: "Yes."
"At the International Congress of Mathematicians?"
Li Mu nodded again: "Yes."
At this time, Wiles and the others couldn't help but gasp.
Good guy.
This mathematical hypothesis crusher is now going to attack another difficult problem?
It is also one of the seven major mathematical problems of the millennium.
Perhaps it is not as famous as Goldbach's conjecture in terms of popularity, but in a practical sense and in terms of its significance to the mathematics and physics circles, the proof of this problem is very huge.
The solution of this problem will not only help researchers related to fluid mechanics in reality to conduct analysis, thereby helping human life, but it also represents the end of the last problem of classical physics.
"Are you sure?" Wiles asked again.
Li Mu thought for a moment, finally nodded, and said with a smile: "If you had asked me before this class, I might have said that I am not very sure, but after this class I would like to say that I am already very sure. ”
"There are still four months left before the start of the International Congress of Mathematicians. This time is enough."
"Four months..." Wiles said: "I remember that the original report of the International Congress of Mathematicians must be sent at least three months in advance, right? So, strictly speaking, you only have one month left."
Li Mu raised his eyebrows and said with a smile: "Although the plenary report meeting lasts for one hour, this time is not enough for me to talk about it."
"So I'll probably tell it separately."
"The specific situation depends on whether the IMU is willing to give this face."
Li Mu smiled slightly.
His words made several people present a little confused.
Let’s see if IMU gives me face?
IMU is the International Mathematical Union, but why should we look at this kind of thing now?
However, Wiles remembered something, and then he smiled, stretched out his hand, patted Li Mu on the shoulder, and said, "I think they will definitely give you this face."
"Okay, you should be very busy next, so we won't disturb you anymore. We look forward to your performance at the International Congress of Mathematicians."
