Chapter 121 Research Project Started

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

"Well, did I fall asleep like this last night?"

Stretching, Xu Chuan looked out the window and muttered to himself.

Fortunately, there was air conditioning in the dormitory, otherwise I would have gone to the hospital this morning after sleeping like this.

It was still a bit cold in the early spring night of March.

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, which was a little messy and even a little wrinkled due to sleep pressure.

Last night, he sorted out the materials and the deformation transformation Xu-Weyl-Berry theorem until more than three o'clock in the morning, so that he couldn't bear it and fell asleep on the table without taking Red Bull.

However, hard work is rewarded with results.

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

The rest is to gradually improve it. With his efficiency, it is estimated that it will be done in about two or three days.

Of course, this does not mean that it can be completely improved to the point where it can be published in a journal, but that the Xu-Weyl-Berry theorem after deformation and twisting can be used to calculate Betelgeuse.

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

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

Thinking of this, Xu Chuan stuffed the bread corner in his hand into his mouth, sorted out the manuscript paper on the table, picked up the phone and called his senior brother Fan Pengyue.

He has to complete the establishment of the scientific research project in the next two days.

Although his follow-up research project on the Xu-Weyl-Berry theorem has been given the green light by the higher-ups, the formal procedures still have to be followed, but the review time will be compressed to the extreme.

If you follow the normal ordinary project application, it will definitely be too late.

Ordinary project applications are time-limited, and the general deadline for submission is about one to two months.

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

So in general, it takes about 3 months from application to project establishment.

As for his side, it can't be compared with ordinary projects. The follow-up research project on Xu-Weyl-Berry theorem has been reported before, and the higher-ups have given the green light and approved it quickly.

So he just needs to cooperate with Fan Pengyue to establish the relevant projects in the next two days, and then the South China University will quickly transfer the 2.4 million project funds to a special account.

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

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

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

Everything is going smoothly, and even the senior brother Fan Pengyue helped find a few doctoral students in the astronomy department to join the research and development team.

Of course, they are hired.

However, for these doctoral students, they are willing to be hired. Not to mention the project allowance, even if they have to pay money, they will participate.

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

In the past many years, students who dared to apply for the astronomy major were generally regarded as more "idealistic" people, because it is not easy to find a job after graduation.

The main employment direction of the Department of Astronomy is to work in scientific research institutions in applied cross-disciplinary enterprises such as observatories, meteorological bureaus, aerospace, national defense, geodesy, and some universities. The positions can be said to be scarce.

After all, in China, those who are capable and willing to study astronomy belong to the major universities of the country. Capitalists will not invest money in this at all. This is obviously a matter of throwing money at it without any income.

There are people who do the business of killing their heads, but there are no people who lose money.

Only units like the state can invest some funds every year to do these things.

Therefore, astronomical jobs are the kind of jobs with many people and few porridge, which need to be fought for.

If you can participate in a large-scale scientific research project during the student stage, it 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 booked a private room and invited several doctoral students to have a meal together before the project started.

"Dear seniors, I toast you a glass of beer and wish you a happy cooperation in the subsequent scientific research projects."

In the private room, Xu Chuan stood up with a glass of beer and said to several seniors from the Department of Astronomy in the private room with a smile.

Whether in China or abroad, things like human relations are inevitable, but the human relations exchanges in China are more in-depth.

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

"Cheers to God Chuan."

"I wish God Chuan's research project a success."

"Keep going."

"."

Xu Chuan stood up to toast, and several doctoral students in the Department of Astronomy also stood up quickly, holding disposable plastic cups and drinking the beer in the cups.

"Everyone, please don't be polite. It's time to eat and drink tonight. From tomorrow, I will bother you."

Xu Chuan smiled and sat down. He was not very good at interpersonal relationships, but he could still handle things like treating people to a meal.

"Well, what's the trouble? People in the Department of Astronomy can participate in scientific research projects, which is something that others can't ask for."

"That's right, I've already studied for a doctorate, and this is my first time participating in a scientific research project."

"Chuan Shen, is your project this time to observe and collect data on Betelgeuse?"

At the dinner table, perhaps because they were not facing their own mentors, the atmosphere was much more relaxed. After a few glasses of beer, several 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 became the research target."

"Betelgeuse, the one on the Orion arm, is indeed a good research object, but Chuan Shenni, are you 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 the case. It's mainly to use the Xu-Weyl-Berry theorem to make an accurate judgment on the size, diameter, and mass of Betelgeuse."

"Hmm? Hasn't the size and mass of Betelgeuse been measured long ago?"

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

A doctoral student named Liu Xuan, who was sitting next to Xu Chuan, asked in confusion, and then listed a series of various parameter information of Betelgeuse.

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

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

"That's right, because the distance is too far, the estimation of its mass is not accurate, so the deviation is large."

Liu Xuan nodded, then reacted, looked at Xu Chuan in surprise, and asked, "Chuan Shen, you don't want to measure its precise mass, right?"

Xu Chuan nodded.

After getting confirmation, the doctoral student in the astronomy department looked at Xu Chuan with eyes like a monster, and the situation of the 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 was impossible. After all, you can solve something that the entire astrophysics community has not done?

But considering that the junior in front of him had proved a world-class conjecture in his freshman year and might win the Fields Medal in two years, the words that were about to come out of his mouth finally changed to another question.

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

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

Next to him, several doctoral students in the astronomy department were confused and had no idea what this junior was talking about.

Xu Chuan sighed and asked, "Okay, it seems you didn't understand. Let me ask you a question. If there is a drum in the distance that you can't see, and the sound of the drum reaches your ears, do you think you can judge the size and shape of the drum in the distance by the sound of the drum you hear?"

"Impossible!"

"How can you judge this?"

"Chuan Shen, you must have super hearing. It would be a miracle if you can hear this."

When this question came out, several doctoral students shook their heads and replied, only Liu Xuan beside him asked curiously.

"Can it be done using the theorem you proved before?"

Xu Chuan shook his head: "No, this is not my research achievement. In fact, as early as the last century, mathematicians could determine the size and shape of the drum by judging the sound of the drum, but it just requires some conditions."

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

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

"Although it sounds magical, theoretically, this can indeed be done, and this is what I am studying this time."

In the box, several doctoral students looked at Xu Chuan blankly, still a little unbelieving.

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

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

And now this freshman student in front of them told them that he had a better method that could accurately measure and calculate the mass of stars.

Isn't this the most outrageous thing to open the door to outrageous things?
