Chapter 118 Mathematical Physics Research Group Meeting
Chapter 118 Mathematical Physics Project Group Meeting
After getting a pile of book lists from Wang Wei, Lin Xiao did not rush to find them, but first added the authoritative signal of Academician Tang Qing.
"Hello, Academician Tang, I am Lin Xiao"
Soon, the other party responded to the message.
"Hello, classmate Lin, I've heard of you for a long time."
"Just like that, there are still many things that I have to ask my seniors for advice."
"Stop talking about this. Those who learn first come first. Okay, let's not talk about this for now. Wang Wei said you plan to join our project, right? Why are you thinking about studying physics?"
"Actually, it was Wang Wei who recommended me. Wang Wei was the counselor in our class, and I lived with him some time ago due to some circumstances. He knew that I was interested in physics, so he recommended me to try in your research group.
one time"
"Haha, I know. A few days ago, Wang Wei told me about the weakly damped wave equation problem that you helped him solve. He said that you have not learned those physical terms, but can you see the physical meaning behind it through mathematical formulas?
』
"Well, that should be it."
"That's OK. This shows that you are also very talented in physics. So let's do it. Our research group will have a group meeting at three o'clock in the afternoon on Friday next week. You can come to our school then.
International Mathematical Research Center, Conference Room 511 on the 5th floor. You can get to know the other people in the research group then.』
"OK."
…
Now that he had decided to join this topic, Lin Xiao began to study related knowledge with peace of mind. If he wanted to understand the Navierstock equation, he must first learn fluid mechanics.
The status of fluid mechanics in physics can be said to be quite high. At the same time, it can also be called the only unsolved problem in classical physics.
Fluid naturally refers to something that flows.
Everything from all the oceans on the earth to as small as the morning dew on a leaf all fall within the boundaries of fluids, but obviously, fluids do not only refer to liquids such as water.
Even air or the flames ejected from rocket engines are fluids, including the asphalt on the highway, which is also a fluid.
Studying their classical mechanical properties has become a major problem that countless physicists have been studying deeply and have always been unable to extricate themselves from.
For example, how to make the aerodynamic performance of those flying in the sky and running on the ground better, and how to make those running on the sea and swimming in the water quieter and faster. These are all industries that relevant researchers need to be involved in. At the same time,
It is precisely for this reason that countless results have been kept in laboratories as core secrets by various countries and are not allowed to be released.
After all, if you change these things into different forms, it becomes how fighter jets can fly faster, how missiles can fire more accurately, how warships can perform better, and how nuclear submarines can fly faster and quieter.
Perform missions in the deep sea.
Of course these secret technologies will not be made public.
However, the project that Lin Xiao participated in was certainly not to study something related to the military industry, but a purely theoretical research.
Of course, there is no guarantee that these basic theories will not have an impact on practical applications, but this is not something Lin Xiao should consider now.
He has not entered the application field yet.
…
Just like that, time passed quickly.
It was the weekend after the military training, so the freshmen who had just finished the military training briefly enjoyed two days of rest. Then the new week began, and the freshmen ushered in their first class of college.
For Lin Xiao, attending classes is basically meaningless. Just look at what they learn. The only thing that gives him a headache is the series of political courses. The key is the 18 credits. He doesn’t even want to take them.
No, and it’s not possible to apply for exemption. Application for exemption is not allowed for such basic courses.
There is no other way but to learn honestly.
For example, they had an ideological and political class on Tuesday. During this class, Lin Xiao felt drowsy for the first time in a long time. In the end, he chose to read directly.
As for courses in other majors, you can apply for exemption from standing. At first, Lin Xiao felt that as a student, he had to take a few classes to express himself. However, after taking one class of mathematical analysis, he gave up.
He knew everything, but it was so boring to listen to the class.
This is like driving a max-level account to the Novice Village to kill level 1 mobs. Although you can kill them one by one, it is still a bit boring.
So he didn't waste any time and directly applied for all the courses that could be exempted. When the teachers saw that it was him who was applying, they basically gave him the pass without saying a word.
This is equivalent to saying that he only needs to take politics and physical education classes in the future.
And this left him a lot of time, so his work and rest time was basically determined from now on.
That is to get up at eight o'clock every morning, have breakfast, arrive at school before nine o'clock, attend classes and eat, and spend the rest of the time in the library.
Although as a celebrity in the school, he would sometimes be recognized, but because he was in the library and it was Shangjing University after all, the most people could do was be surprised or take a secret photo, but not much else.
It disturbed him, which also allowed him to study with peace of mind.
Then at ten o'clock in the evening, he left on time and arrived at the bus station just in time to catch the last bus back to Yanbeiyuan.
After returning to the house, I will continue to read for a while if I have time. If I am tired, I will wash up and go to bed directly.
This is Lin Xiao's life now.
This kind of rhythm may not be acceptable to others, but he is already used to it and will continue to be accustomed to it in the future.
So the time came to Friday.
The weekly group meeting for the topic [Global Well-posedness of Two-Dimensional Incompressible Elastodynamics] has begun.
Lin Xiao arrived on time at the place where the group meeting started, the International Mathematics Research Center of Peking University.
Of course he knew about the Beijing University International Mathematics Research Center. When he was interviewed by Huaqing Daily, it was nearby, close to the Weiming Lake. The Boya Tower stood on the other side of the lake, and various students could be seen sitting on the lawn and watching.
Books, and some young lovers chirping at each other.
Lin Xiao had no time to appreciate the scenery of Weiming Lake for the time being, so he entered the research center directly and found Room 511.
There are already a lot of people sitting in Room 511. For such an important topic, there are quite a lot of people. Of course, the most important thing is that the person in charge of the topic is an academician, because academician projects can apply for more funds.
Lin Xiao also learned about their funding for this project a few days ago, which was 1.5 million yuan.
This is obviously a very high amount of funding for their basic mathematical theoretical research.
After all, basic mathematical theoretical research does not require any equipment, resources or the like. It can be carried out with just a few people, a few pens, and a few pieces of scratch paper.
Some people may be confused, where are the funds for researching basic theories?
This is what someone said.
If it is other scientific research projects, such as some experimental projects, the cost of conducting experiments can account for a large part of the money. But it is different for mathematics topics. Do you want to buy chemical reagents to study the basic theories of mathematics?
Do mysterious rituals to communicate with God, and then let God tell you the answer?
Only those who supervise the use of funds will believe it.
Therefore, the bulk of their basic mathematics funding expenditure is to pay salaries to other researchers in the group. It is obviously impossible for the funding applicant to directly pocket the funds. If it is found out, it will be funding embezzlement.
However, this does not mean that participants in mathematics projects will get more money, because this has a premise, that is, this mathematics project must be able to apply for so much funding, and generally speaking, mathematics projects
It is difficult to apply for more than 600,000 yuan in funding. If you want to switch to other subjects, the average cost is estimated to be around 1 million.
Lin Xiao and his colleagues were able to get 1.5 million for this project because the person in charge was an academician.
However, it is precisely because Lin Xiao and the others have enough funds for this project that even those intern researchers can earn thousands or even tens of thousands a month, and then hire one or two more powerful professors to complete the project for several months.
By the time we get down, the money has almost been spent.
"Classmate Lin Xiao, you are here."
When Lin Xiao walked in, an old professor sitting inside saw him and waved to him.
Lin Xiao quickly recognized that this was Academician Tang Qing. Since he wanted to participate in this research group, he naturally checked Academician Tang Qing's information before to know what he looked like.
"Academician Tang."
He smiled and nodded at the old professor, and then walked over.
Seeing Lin Xiao walking over, Tang Qing said to the others: "Come, let me introduce to you our new member, classmate Lin Xiao, who is also a rising star in our mathematics community. I have told you before."
Everyone else looked at Lin Xiao, including several graduate students, postdocs in the research center, and a professor who was also in the research group, and then they clapped politely and nodded towards him.
They had all learned from Tang Qing that Lin Xiao was joining, but most of them were still a little reluctant.
Although they had to admire Lin Xiao's achievements in mathematics, in terms of achievements alone, Lin Xiao's one-hour report at the International Congress of Mathematicians was much more impressive than their previous achievements.
times.
But no matter what, these achievements are all in the field of number theory. Even the important conjecture proposed by Lin Xiao is in algebraic geometry, and the topic they studied is the N-S equation in partial differential equations, which belongs to the world of mathematical physics.
thing.
And they have never heard of Lin Xiao's achievements in this area.
Therefore, they basically don't think that Lin Xiao can make much contribution to their research. After all, the lines are as separate as mountains, even though the problem they are researching is not very different from the field of mathematics.
