After two days of exchange reports, two days of meeting charters, and some time spent receiving awards and other matters, Xu Chuan has been in Stockholm for nearly a week.

For a week, he didn't have much time to rest in the first few days, and he had to deal with the greetings from academic friends, lectures, and international scientific seminars.

The first two are easy to say, and you can deal with them and get things done.

But the latter is not coping.

The international scientific symposium that follows the Cafford Prize will be discussed and defined as the future of the winners' respective disciplines.

This meeting is very intrusive.

The conference on mathematics is a little simpler, although Xu Chuan won the Cafford Mathematics Prize, there are too many top stars in the mathematics world, and this aspect does not need him to pay attention to it now.

The communication between the top elders, such as Deligne, Faltings, Gaurs, and Tao Zhexuan, was the core of the meeting, and Xu Chuan occasionally interjected two sentences to express some of his own opinions.

Moreover, the road of mathematics does not need to be guided by the international scientific symposium after the Cafford Prize, this conference, after all, mathematics has its own international mathematical conference.

Therefore, this conference is not so much a symposium on the development of planning mathematics as an exchange between big bulls.

Xu Chuan also reluctantly entered the ranks of 'big bulls'. Although for now, it is only hanging at the end.

However, the meeting of the astronomical discipline cannot play soy sauce.

Because the method of calculating the parameters of astronomical objects according to the xu-weyl-berry theorem is important for the astronomical community.

The ability to calculate some of the parameters of distant celestial bodies more accurately, although not all, or even a small part of the information needed by the astronomical community, is still extremely important.

Because it can help astronomers more accurately determine the state of distant celestial objects, it is undoubtedly very important for the future of mankind.

For example, Betelgeuse.

This red supergiant star 640 light-years away has been active in the astronomical community since it was last revealed by Xu Chuan that there is an associated star in its hydrogen envelope.

Countless telescopes, satellites and other astronomical equipment have set their sights on this huge old star, hoping to find more secrets from it, or judge its current precise state of life.

Betelgeuse is too close to Earth.

The distance of 640 light years sounds very far away, but on the scale of the universe, it is tantamount to if you live in 403, it lives in 404, you open the door and it is its home, and when it opens the door, it is your home.

And the neighbor also packed hundreds of pounds of TNT in his home.

Once it explodes, no one knows if the wall between the two houses will be able to stop it.

That's what astronomers are worried about now, although based on previous observations and calculations, the explosion will leak out of SCP-403's window and will not affect SCP-404.

But now all of a sudden someone tells you that the wall between your two houses may be of inferior quality, or that TNT explosives may have been directed blasting, and that they may be facing your home.

Who can not worry about thisTM?

.......

At the Astronomy Symposium of the Cafford Prize, Xu Chuan, as the founder of the method of calculating the actuarial parameters of the Xu-Weyl-Berry theorem, made remarks that were naturally relevant.

Promoting the methods created by oneself can be said to be the lifelong dream of every researcher or scholar.

Even if they don't like their achievements being used in military affairs, Einstein and Grothendieck, who burned their manuscripts in their old age and lived in seclusion since middle age, still hope to see one day that their research results are widely used in the scientific community and confirmed.

Xu Chuan naturally hopes that his research results will be widely used in the scientific community and all walks of life.

However, the mathematical tools used in the method of calculating celestial parameters using the xu-weyl-berry theorem are somewhat too esoteric for the astronomical community.

Although this is nothing to the mathematical community, for astronomers, most of whom can only use mathematical methods such as Kepler's three laws, it is tantamount to a book from the sky, which cannot be read.

For this, Xu Chuan doesn't have a good way for the time being.

This is not something that can be solved overnight, and it will have to wait for these astronomers to learn to use this tool.

However, at the meeting, Xu Chuan had another improvised idea in his heart that he didn't say.

That's modeling.

A mathematical model was established for the method of calculating the actuarial parameters of the xu-weyl-berry theorem.

Although the calculation of different parameter information, different celestial objects, and even different species of stars, such as red dwarfs, orange dwarfs, and brown dwarfs, need to be used in different ways to do different torsional transformations of the xu-weyl-berry theorem.

Even many Xu Chuan himself has not yet begun to study and deal with it, but it can be unified after all, and the types of stars are also limited.

Stars, planets, neutron stars, black holes, all kinds of celestial bodies, even according to the classification of small units, the number of types can be counted.

Coupled with the fact that the root of all calculation methods is in the reversal of the xu-weyl-berry theorem, if he does not dislike the trouble, it may take a few years or more than ten years to write a complete set of mathematical models.

At that time, astronomers only need to input the observed corresponding parameters into the mathematical model, and then click the button to calculate the required parameter information.

This is not like the previous mathematically calculated particle channels that cannot be generalized and cannot be modeled.

The method of calculating the parameters of the actuarial object of the xu-weyl-berry theorem makes it possible to build a mathematical model, although there is a lot to write, but it can be done.

Undoubtedly, this is indeed very convenient.

But for Xu Chuan, this is a super troublesome and super time-consuming thing.

If it were someone else, maybe they would have spoken out their thoughts at the meeting as soon as their brains were hot, and then they would be harassed by the astronomical community day and night.

After all, he is the only one who has the ability to make this model now.

So for the sake of his own tranquility, Xu Chuan directly held this idea in his heart.

After a few years, when enough people in the mathematical or astronomical community understand the xu-weyl-berry theorem, the idea can be proposed.

Of course, more importantly, his ambition is not in the astronomical world, and he does not pay much attention to and care about the results of the astronomical community.

After all, as far as the current technology is concerned, even if he plays tricks in the astronomical world, finds hundreds of terrestrial planets or immigrated planets, or discovers some great achievements, or even finds the legendary white hole or something, it is not of much use.

These discoveries may have earned him the Nobel Prize and a greater place in the astronomical community. But to be honest, he was not very interested in the Nobel Prize, nor was he interested in the status of the astronomical community.

It can even be said that those awards that have not been won, such as the Cafford Prize, the Abel Prize, the Wolf Prize and other awards, are more attractive to him.

Or, using the knowledge in his mind to perfect a technology or theory is more satisfying than gaining a higher status in the astronomical world.

......

After a week in Stockholm, Xu Chuan won the Cafford Prize in Mathematics and Astronomy, and received two medals made of pure gold, two certificates, and a prize of 1 million meters of gold.

The prize money of the Cafford Prize is 500,000 meters of gold for a single event, and he won the mathematics prize and the astronomy prize at the same time, which is 1 million meters of gold.

If you look at the amount of prize money alone, almost two Cratford Prizes are worth one Nobel Prize.

But in fact, when it comes to individual prize money, the Craford Prize has often won more than the Nobel Prize.

The reason is very simple, the Nobel Prize is generally awarded to two or three people.

And the Clafford Prize, most of the time, there is basically only one winner.

If the Nobel Prize is awarded to three people, it will be about 1 million meters of gold for three people, and about 330,000 meters of gold for each person, which is not comparable to the Cafford Prize.

Of course, the significance of an award does not lie in the amount of prize money.

The prize money is just a gift attached to the winner, more or less, it is only symbolic.

After all, people who can win the Nobel Prize or the Craford Prize have made contributions to academia or society far more than they can get from these awards.

.......

With the certificate and the bonus, Xu Chuan returned to Princeton and returned to campus life.

"Xu, are you ready to graduate?"

In Professor Pierre Deligne's office, Witten and Deligne were both there, and the two old men looked at Xu Chuan, who was sitting on the other side, and asked.

This was a matter discussed by the two old professors when Xu Chuan was still holding a report meeting in Stockholm.

After all, with their student's achievements in mathematics and physics, it was enough to graduate from Princeton.

Although he has only been in Princeton for more than half a year, Princeton does not pay attention to this, whether it is half a year or three years, Princeton only looks at ability.

The ability is sufficient, let alone half a year to graduate, it is no problem to study for half a year and then directly work as a professor at Princeton.

"It's too early, teacher, there's still a lot to learn."

Xu Chuan shook his head and replied, he had already been able to graduate, but graduating now did not meet his original intention of coming to Princeton.

He came here to study mathematics and physics, to learn knowledge.

Especially after he had seen that when he had enough mathematical ability to have a delicate chemical reaction with physics or other subjects, he didn't want to graduate early.

】

Now there are two super bulls Witten and Deligne as his mentors, and before the knowledge of these two mentors is squeezed out, it is better to postpone graduation a little.

Both Drinne and Witten had enough knowledge to teach him.

"Are you really not thinking about graduating?"

Deligne took a sip of his coffee and continued, "You can still choose to stay at Princeton after graduation." ”

"Whether it's a postdoctoral fellow or a professor at Princeton, you can do it, and if you win the Cafford Prize in Mathematics, you are fully qualified to be a full professor at Princeton University."

Hearing this, Xu Chuan smiled and said, "Nineteen-year-old professor of Princeton University, this is really breaking history, I remember that the youngest full professor of Princeton seems to be the thirty-five-year-old Professor Shi Yigong, right?" ”

Deligne nodded and said, "Professor Shi is quite an excellent person, but what about your choice?" ”

Xu Chuan smiled and declined, "Nineteen-year-old full professor Princeton, this is indeed very tempting, but in comparison, I prefer to study here." ”

This answer is actually a pun.

It answers Professor Deligne's question, but it also means that he will not be a professor at Princeton, but only a place for him to study.

Of course, Xu Chuan doesn't mind the title of honorary professor or tenured professor that he doesn't hold.

"Since you insist, then whatever you want."

For Xu Chuan's choice, Deligne and Witten had no surprises, this student has always been like this.

What's more, the age of eighteen or nineteen years old is the time to learn.

Even though you can study after graduation, studying on campus and studying in society are two completely different states.

Different identities and different statuses naturally lead to different learning statuses.

......

After rejecting the proposal of the two tutors to graduate early, Xu Chuan re-entered his daily study.

It's just that it's December now, and there isn't much time left for this year's study, after all, it's certain to go back for the New Year.

The days passed like this, and in the blink of an eye, the time had reached the middle and late twelfth month of the Chinese lunar calendar.

In a few days, it will be the Spring Festival in China.

At the same time, Xu Chuan also put away his heart of learning a little and prepared to buy a ticket to go home for the New Year.

But to some surprise, before leaving, the Ivy League Diet Club at Princeton University, which he often went to, didn't know where to find out about his lunar birthday, so he rented the school's auditorium and held a birthday party for him.

In addition to the members of the club, there were many other students, and even several top professors such as Deligne, Witten, and Fepferman came.

Although these professors just came over to say happy birthday and left, it is really touching that there are still people who remember his birthday in a foreign country.

......

After spending the 12th New Year in his hometown, Xu Chuan said goodbye to his parents and returned to Princeton.

Compared with last year's high-profile, he has made certain achievements in mathematics, physics, astronomy and other fields, and after the start of school this year, he will undoubtedly be much more low-key.

Except for some awards awarded to him, other things, whether it was interviews or asking him to give a report, were all rejected by him.

In this way, Xu Chuan followed the two tutors and devoted himself to learning mathematics and physics.

In the blink of an eye, nearly half a year has passed, and it is July.

In mid-July, something big happened in the world of mathematics.

Professor Mariam Mirzahani, the only woman in mathematics to have won a Fields Medal so far, died of breast cancer on July 15.

He was only forty years old.
