Chapter 112 Professor Delignes invitation and Princeton making an exception
In addition to congratulations and congratulations, Academician Zhang Weiping also persuaded Xu Chuan for a long time in the hotel room, trying to get him to temporarily give up physics and concentrate on studying mathematics.
However, Xu Chuan pushed left and blocked and refused to give a clear answer or reply.
Is it possible for him to give up physics? It's impossible.
The purpose of learning mathematics is to make further progress in physics. This idea has not changed even if he proves a world-class problem.
However, the deeper he studied mathematics, the more Xu Chuan felt that mathematics was really profound and profound.
Even if he proved Weyl-Berry's conjecture, he would still feel like he just picked an apple in a huge orchard.
And there are not many apples in the orchard of mathematics that are bigger, brighter, and sweeter than the Weyl-berry conjecture.
The road to climb is still quite long.
With his current achievements and achievements, he has just begun.
At most, when you reach the foot of Mount Everest, you can look up and see the backs of those great predecessors climbing up.
In fact, some of them can't even see their backs.
For example, Pope Grothendieck has already stood at the top.
Emperor G's greatest achievement was the creation of the modern algebraic geometry branch, which provided the possibility to unify various branches of mathematics.
This radiates the entire field of mathematics. There are few contemporary mathematics that are not affected by algebraic geometry. This achievement has an unparalleled impact on the entire contemporary mathematics!
Since the development of algebraic geometry, it can be said that algebraic geometry is the pinnacle of abstraction in the history of mathematics and the future of mathematics.
In addition, Huang Huang also developed a large number of new mathematical structures, such as general forms, motivations, ultimate cohomology, category theory, topology and a series of new mathematical structures.
These things reached the extreme and pinnacle of abstraction in the history of mathematics under Emperor G, and no one can fully understand them to this day.
But it is obvious that these are the centers of the future of mathematics, and with a slight breakthrough, they can be recorded in the history of mathematics.
Looking at the number of contemporary Fields Medal awards for algebraic geometry, we can see from one aspect the profound influence of Emperor G on contemporary mathematics. In the second half of the 20th century, Emperor G's status was unparalleled.
Now, let alone chasing the Pope, he can't even see his back.
The proof of Weyl-berry's conjecture is just the starting point to the highest peak.
As for graduation, Xu Chuan feels that it is almost done.
His grades in mathematics are definitely enough for him to graduate, but he also needs to do some hard work in physics.
I can’t accept the fact that I proved a world-class mathematical conjecture, but accomplished nothing in physics and graduated with no achievements.
Xu Chuan thought about it and felt that he might have a bit of obsessive-compulsive disorder.
Because he felt that since he was a double major, there was no reason for his grades in physics to be worse than those in mathematics when he graduated.
So after this mathematics exchange meeting, Xu Chuan also prepared to do something in physics to bring his university to a close.
As for the scope of what is created, there are generally two aspects.
One is particle physics, which he studied in college.
On the other hand, it should be about Betelgeuse.
This has something to do with the use of Weyl-berry's conjecture after it is proved. As a prover and a student of physics and mathematics, he has no reason not to take the lead in developing and using it.
And he himself is also quite interested in the current status of Betelgeuse.
This red supergiant star, which is only more than 600 light-years away from the solar system, has now reached the end of its life.
Perhaps, one day in the future, people will be able to see it turn into a supernova as bright as the moon in the sky, and then slowly turn into a dazzling and beautiful nebula in the universe as time goes by.
And then give birth to one or several stars again.
This will be a carnival for the astronomical community and may also bring new discoveries to the physical community.
In the last years of a massive star, a supernova explodes at close range, which is enough for humans on earth to observe a lot of things.
So Xu Chuan is quite interested in Betelgeuse and wants to see if he can observe it with the help of NTU's astronomical telescope equipment.
Then use the Weyl-berry conjecture to make an accurate judgment on it, determine its size, and then determine which step it has reached in its old age and how long it is until it explodes as a supernova.
This is indeed a very interesting and meaningful thing.
...
After resting for a while in the hotel room and sorting out the inspiration and ideas he had generated during today's presentation on stage, Xu Chuan went downstairs again.
Today is the fourth day of the exchange meeting, which can also be said to be the last day.
Because there are no lectures or evening parties arranged on the fifth to seventh days, only mathematics professors from all over the world can freely move around Princeton and exchange academic ideas.
So on the night of the fourth day, there will be the grandest party and dance.
Although Xu Chuan is not interested in the dance, he cannot miss the party.
However, he still underestimated the sensation caused by proving a world-class mathematical conjecture on the stage.
When he stepped into the auditorium, many people around him seemed to recognize him, and then many younger scholars gathered around him.
"Are you Chuan Xu? The genius boy who killed Weyl-berry on the stage this afternoon?"
"Can you take a photo with me? I want to post it on Facebook."
"Hi, handsome guy from China, can you give me your contact information? Email is fine. If that doesn't work, let me follow your Twitter. Or you can follow mine on Twitter. My following
There are many beauties inside.”
After struggling to get rid of these enthusiastic and even fanatical scholars, Xu Chuan found Academician Zhang Weiping, who was currently communicating with a mathematician with a cocktail in his hand.
When I saw Xu Chuan coming, I immediately pulled him over and introduced him warmly.
This chapter is not over, please click on the next page to continue reading! "Xuchuan, you are here at the right time. This is Professor Artur Avila, a Brazilian mathematics professor. He has won the European Mathematical Society Award, the Fields Medal and other top-notch
Award, for profound research in chaos theory, the field of dynamical systems and spectral theory."
"Hello, Professor Avila." Xu Chuan greeted with a smile.
"Hello, Xu Chuan, I didn't expect you to be so young." Professor Artur Avila raised a glass of wine and smiled at him, then continued.
"It's a pity that I missed your report meeting this afternoon because of something else. However, I watched the video of the report in the evening. It can be said that this was the most exciting report meeting this year."
"Your understanding of spectral theory, fractal dimensions and the spectrum of fractal measures is simply beyond imagination. It has given me a lot of inspiration, some of which can be quoted in one of my research projects, which can save me several months.
Thank you so much for your time.”
"I don't know if you have time tomorrow. I would like to take up one morning and talk with you about the mathematics of spectral theory."
"Tomorrow morning? Of course."
Xu Chuan agreed with a smile and chatted about mathematics with a Fields Medal winner. This was an opportunity that others could only dream of.
Sometimes, some inspiration from each other can bring great help and inspiration to each other.
What's more, he also wanted to chat with Professor Avila, but not about spectrum theory, but about chaos theory.
This Brazilian and French mathematician won the Fields Medal in 2004 for his outstanding contributions in dynamical systems and analysis.
But his most famous research direction is in the fields of chaos theory and dynamical systems.
The object of study in these fields is a chaotic but somewhat related system. They change over time, but small differences in the initial state can lead to very different results.
Such as the "butterfly effect" in weather patterns.
It's a metaphor used to describe this kind of system - because weather is a chaotic system, the flapping of a butterfly's wings can cause a hurricane to occur hundreds of kilometers away.
One of Avila's main contributions in this field is that he clarified that there is a large class of dynamical systems that will eventually fall into one of two outcomes.
These systems will either evolve into a stable state or into a chaotic random state - although it cannot be predicted accurately, it can be described using probabilistic language.
Well, some are close to the chaotic systems and turbulent systems he studied in his previous life.
This is what Xu Chuan hopes to get most from the professor in front of him.
Because this may be helpful in establishing a mathematical model for the turbulent system.
.......
At eight o'clock in the evening, the party officially started. All kinds of food and red wine were served on the white dining table for everyone to take, including high-quality caviar, deep-sea fish, Australian lobster and other high-quality seafood, as well as various top-notch meats.
with vegetables.
To be honest, in the world of mathematics, Princeton is probably the only one with such strength.
Even the mathematics conference organized by the International Mathematical Union would not have such a sumptuous party.
The richest school in the world has tens of billions of dollars flowing in the stock market and Wall Street every year.
Just as no funding institution on Wall Street will reject students from Princeton’s Department of Mathematics and Department of Economics, with the capabilities of Princeton’s Department of Mathematics and Economics, it is not difficult to control these funds and earn remuneration, and it can even be said to be a very easy task.
Simple things.
Sometimes, if you are lucky, these tens of billions of dollars can bring Princeton a return on investment of more than 10%.
After removing all kinds of expenses, there is still a pure gold profit of more than one billion meters, which can be said to be quite terrifying.
After all, this is not 12,000 yuan, but 30 to 40 billion yuan of funds. In quantitative investment, the larger the fund, the lower the rate of return. This is an almost insurmountable truth.
This is like thinking of principal as a fish and the stock market as a pond.
When the price is 10,000 yuan, the fish is very small. It may be a crucian carp thrown into a pond. At most, it only makes a small splash. Even if there is a strong wind and waves that day, you won’t even see the splash. It can be in it.
Various activities and a good life.
And the principal of tens of billions is a great white shark in the sea. If you throw it into a pond, the splash will blow out part of the water in the pond.
At this time, it is difficult for it to turn around.
The ability to control billions of dollars of gold to wander in the stock market and guarantee to make money is the envy of all fund companies around the world.
In the face of such a large amount of funds, perhaps stock god Buffett and financial tycoon George Soros can use them to make more money and obtain more returns in a certain period of time, but they cannot be like Princeton year after year.
of stability.
Just like Harvard University, it also has its own school fund, and the amount is huge, close to 50 billion yuan, and it can also achieve a return of about 10%.
But after all the bills were paid, Harvard was left with only $300 million in annual profits.
In contrast, one is in the sky and the other is on the ground.
Well, the reason why I mention this is because he also borrowed this fund return system in his previous life and earned several billions and nearly tens of billions of rice gold, and then used this money as a pavement to allow him to pursue his academic career.
After walking a longer distance, I finally stood at the top of the physics world.
.......
Holding the dinner plate, Xu Chuan was selecting food on the dining table when he bumped into an old man wearing a formal dress and his sparse hair was all gray.
"Are you Professor Deligne?"
Xu Chuan recognized the old man in front of him, a close disciple of the Pope, winner of the Fields Medal, a Grand Slam scholar in mathematics, Viscount Pierre René Deligne.
"It's me." Professor Deligne smiled and continued: "You performed very well in the afternoon report meeting."
"Thank you for the compliment."
Xu Chuan showed a bright smile, which was very rare based on his understanding of this old man.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "No need to be modest, I came to you today to ask if you have ever considered furthering your studies in mathematics?" Deligne raised his hand.
He asked after taking a sip from the wine glass.
"Of course." Xu Chuan replied without hesitation.
"Then I am here to invite you to come to Princeton to study for a PhD. If you are willing, I can mail you an invitation letter."
"Of course, your achievements are enough to serve as a professor at Princeton, but I think now is the time for you to learn, and you still have deeper potential to tap."
For the talented young man in front of him, Professor Deligne expressed his hope and invitation without hesitation.
“I remember didn’t you need three letters of recommendation to get a PhD from Princeton?”
Xu Chuan asked curiously. Normally, to study for a doctoral degree from Princeton, you need three letters of recommendation recognized by Princeton, as well as excellent paper grades and proof of academic activities.
In his previous life, it was his mentor Chen Zhengping, a high energy physics professor at the European Atomic Energy Laboratory, and a letter of recommendation written for him by Edward Witten.
"That's for others, for outstanding young people like you, these Princeton can make exceptions, and if you need a recommendation letter, I believe every professor in this auditorium will write it." Professor Deligne
said with a smile.
For a boy who solved a mathematical conjecture at the age of eighteen, some rules can be broken.
Such students are perfect for Princeton.
"Sorry to trouble you, but I may have to wait until September this year, or later, to study for a Ph.D. degree."
"As you know, I am currently studying at Jinling University, but I am double majoring in mathematics and physics, so if I want to come to Princeton, I need to graduate from both courses, which will take some time."
Xu Chuan did not refuse the invitation, but just put forward his own ideas.
"It doesn't matter, it doesn't matter. Princeton's door is always open to you."
Professor Deligne smiled and said: "Enjoy the party and dance tonight, at least half of it belongs to you."
