Great Country Academician

The next day, when the bright sunlight came in through the window, Xu Chuan, who was lying on the table, slowly opened his eyes.

"Well, did you sleep like this last night?"

Stretching, Xu Chuan looked at the bright sky outside the window and said something to himself.

Fortunately, there is an air conditioner in the dormitory, otherwise, if I slept like this all night, I would be in the hospital this morning.

The night in early spring in March was still a bit cold.

After getting up and washing up, Xu Chuan returned to the desk with a piece of bread and a cup of yogurt in his mouth. While eating, he looked at the manuscript paper on the table that was somewhat messy and even wrinkled due to sleep.

Last night, sorting out the data and transforming the Xu-Weyl-Berry theorem tossed until three o'clock in the middle of the night, so that he couldn't hold the red bull and went to sleep on the table.

But hard work pays off.

One night is not enough to transform the Xu-Weyl-Berry theorem from isospectral fluctuations to Sobolev space fluctuations, but part of the core idea has been written.

The rest is to be gradually perfected. With his efficiency, it can be done in about two or three days.

Of course, this fix does not mean that it is completely perfected to the point where it can be published in a journal, but that it can be calculated on Betelgeuse by using the Xu-Weyl-Berry theorem after deformation and twisting.

This is different from publishing a thesis. Publishing a paper is more troublesome than this, and there are many things that need to be improved.

But today there should be no time to continue to improve.

Thinking about it, Xu Chuan stuffed the bread corner in his hand into his mouth, and after tidying up the manuscript paper on the table, he picked up his mobile phone and called his elder brother Fan Pengyue.

He has to complete the approval of the scientific research project in these two days.

Although his follow-up research project on the Xu-Weyl-Berry theorem is given the green light by the higher authorities, formal procedures still need to be followed, but the review time will be shortened to the extreme.

If you declare according to the normal and ordinary topics, it will definitely be too late.

There is a time limit for ordinary project declarations, and the deadline for submitting declarations is usually about one to two months.

There are many uncontrollable factors when the notification time for project approval will be issued. It takes about 3 to 6 months.

Therefore, under normal circumstances, the time from application to project approval is about 3 months.

As for his side, it can't be compared with ordinary projects. The research topic related to the follow-up of Xu-Weyl-Berry theorem has been submitted before, and the green light is also given the green light to approve the whole process quickly.

So in the past two days, he will cooperate with Fan Pengyue to set up the relevant projects, and then the South Assembly will quickly transfer the 2.4 million project funds to a dedicated account.

When the funds arrive, the research on Betelgeuse can be officially started.

After two or three days of tossing with the big brother, the follow-up research project on the Xu-Weyl-Berry theorem finally passed the review.

The special funds for the project will be transferred to a dedicated account in three days, and in a few days, all kinds of astronomical equipment used to observe Betelgeuse will be vacant.

Everything went smoothly, and even senior brother Fan Pengyue helped find a few doctoral students from the Department of Astronomy to join the research and development team.

Of course, the hired kind.

But for these doctoral students, they are willing to hire them, not to mention the project allowance, even if it is a subsidy, they have to participate.

The Department of Astronomy is in Nantah, no, it is a well-known unpopular major in the whole country, with few people, few scientific research projects, and even less scientific research funds.

In the past many years, students who dare to apply for astronomy majors are generally regarded as relatively "ideal" people, because it is not easy to find jobs after graduation from this major.

The main employment direction of the Department of Astronomy is to work in scientific research institutions in applied interdisciplinary enterprises specializing in astronomy such as observatories, meteorological bureaus, aerospace, national defense, and geodesy, as well as teaching and research work in some colleges and universities. The positions can be said to be rare.

After all, in China, those who have the ability and know how to study astronomy belong to the major universities in the country. Capitalists will not spend money on it at all. This is obviously a matter of throwing money into it without any income.

Some people do the business of beheading, but none of them lose money.

It is also a unit like the state that can invest some funds to do these things every year.

Therefore, astronomy jobs belong to the kind with many people and few food, and they need to be competed for.

If you are a student, you can participate in a large-scale scientific research project, which will definitely be of great help to your resume after graduation.

In Xiaoxianzhuang, the day before the Betelgeuse observation project was officially launched, Xu Chuan reserved a private room and invited several doctoral students and seniors he hired to have a meal together before the project started.

"Seniors, I would like to offer you a toast, and wish us a happy cooperation in the follow-up scientific research projects."

In the box, Xu Chuan stood up holding a glass of beer, and said to the seniors of the astronomy department with a smile.

Whether it is in the country or in the country, things like human relations and sophistication are unavoidable, but the domestic exchanges of human relations are more in-depth.

A simple meal can be exchanged for the full help of these doctoral students for the next 20 days, even if he pays for the treat himself, it is worthwhile, not to mention that it can be reimbursed through scientific research funds.

"Respect the God of Sichuan."

"I wish Chuan Shen's research project success."

"come on."

"."

Xu Chuan stood up to toast, and several PhD seniors from the Department of Astronomy also stood up quickly, holding the disposable plastic cups and drank the beer in one gulp.

"Everyone, you are welcome. I should eat and drink tonight. I will trouble you from tomorrow."

Xu Chuan sat down with a smile. He is not very good at dealing with interpersonal relationships, but it is still possible to treat guests to a meal or something.

"Hey, don't worry about it. People from our astronomy department can participate in scientific research projects, which no one else can ask for."

"That's right, I'm already a doctoral candidate, and this is my first time participating in a scientific research project."

"Chuanshen, is your project this time to observe and collect information on Betelgeuse?"

At the dinner table, the atmosphere was a lot more relaxed, perhaps because they were not facing their own mentors. After a few glasses of beer, the fellow doctoral students gradually relaxed a little.

Hearing the question, Xu Chuan nodded and said, "Well, this project is actually a derivative study of the Weyl-Berry conjecture."

"And Betelgeuse is quite suitable, so it has become a research target."

"Betelgeuse, the one on Orion's cantilever, it is indeed a good research object, but Kawasami is worried about its supernova explosion?"

In the box, a doctoral student asked with a smile.

Xu Chuan shook his head and said, "That's not true. It's mainly to use the Xu-Weyl-Berry theorem to make an accurate judgment on Betelgeuse's size, diameter, and mass."

"Huh? The size and mass of Betelgeuse have been measured a long time ago?"

"If I remember correctly, it is a red supergiant star with a spectrum of M1-2 type, located in Orion, with a radius of about 887 to 955 times that of the sun, and a distance of about 640 to 724 light years from the earth. Varies between 0.0 and 1.3"

Sitting next to Xu Chuan, a doctoral student named Liu Xuan asked suspiciously, and then listed a series of various parameters of Betelgeuse.

Xu Chuan smiled and said, "But it's not accurate, is it? These are all estimates."

"For example, the quality of Betelgeuse has always been controversial. Some data show that its mass is only 14~15 solar masses, but some sources believe that its mass reaches 18~19 solar masses, and some even reach 20 solar masses. .”

"Indeed, because the distance is too far, the estimation of its mass is not accurate, so the deviation is very large."

Liu Xuan nodded, then came to his senses, looked at Xu Chuan in surprise, and asked, "God Chuan, don't you want to measure its precise quality?"

Xu Chuan nodded.

It was confirmed that the doctoral student brother from the Department of Astronomy looked at Xu Chuan with the eyes of a monster, and the situation of several other people in the room was similar.

"Can this be done?"

After a long pause, Liu Xuan asked hesitantly.

He originally wanted to say that this is impossible. After all, you can solve things that the entire astrophysics community has not done?

But considering that the junior in front of him proved a world-class conjecture in his freshman year and might win the Fields Medal two years later, the words that were on his lips were finally replaced by another question.

Xu Chuan grinned, and said: "Of course, the Xu-Weyl-Berry theorem is the study of this. It can use the eigenvalues ​​and boundary points, supplemented by standing wave solutions, and use the separation of variables method to determine the source of the information wave. information such as shape and volume”

"At the beginning, it was used to study two-dimensional waves, but I extended it to the high latitude world"

Beside him, several PhD seniors from the Department of Astronomy were stupefied and had no idea what this junior was talking about.

Xu Chuan sighed, and asked: "Okay, it seems that you didn't understand, how about this, let me ask you a question, if there is a drum in the distance where you can't see, and the sound of the drum reaches your ears , do you think it is possible to judge the size and shape of the distant drum from the sound of the drum heard by the ear?"

"impossible!"

"How do you judge this?"

"God Chuan, I'm afraid you have good ears. If you can hear this, you'll be damned."

As soon as this question came out, several doctoral students shook their heads and answered, only Liu Xuan beside him asked curiously.

"Could it be possible to use that theorem you proved before?"

Xu Chuan shook his head: "No, it's not my research achievement to do this. In fact, as early as the last century, mathematicians were able to determine the size and shape of drums by judging the sound of drums. Just some conditions."

"Listening to the sound to distinguish the drum shape is the two-dimensional proof of the Weyl-Berry conjecture, and I have extended the two-dimensional proof to high latitudes, so it can be used to judge the mass and volume of stars."

"You can regard the stars in the distant starry sky as a drum. The radiation waves, gravitational waves, space distortion and other information of the stars are the key points I use to judge its precise size, volume, and shape."

"Although it sounds miraculous, theoretically speaking, this is indeed possible, and my research this time is exactly this."

In the box, several doctoral students looked at Xu Chuan blankly, still in disbelief.

In their concept, the calculation of the mass of a star is generally done through common methods in the literary world, such as the law of universal gravitation, gravitational redshift, and luminosity calculation.

Although the calculation of the mass of stars in distant galaxies is not very accurate, there is no other way.

But now the freshman in front of him told them that he has a better method that can accurately measure and calculate the mass of stars.

Is this outrageous fucking open the door for outrageous, outrageous home?
