The next day, when the bright sunshine filtered 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 out the window at the bright sky and muttered to himself.
Fortunately, there is air conditioning in the dormitory. Otherwise, after sleeping like this all night, I would be in the hospital when I woke up this morning.
It was still a bit cold on a spring night in early March.
After getting up and washing up, Xu Chuan returned to the desk with a piece of bread and a cup of yogurt. While eating, he looked at the manuscript paper on the table that was a little messy and even wrinkled due to sleep.
Last night, he worked hard on sorting out the data and deformation transformation xu-weyl-berry's theorem until around three o'clock in the night. In the end, he couldn't bear it and fell asleep on the table without eating Red Bull.
But hard work pays off.
Although one night is not enough to transform the xu-weyl-berry theorem from an equispectral fluctuation into a Sobolev space fluctuation, part of the core idea has been written down.
The rest is to be perfected slowly. With his efficiency, it can be completed in about two or three days.
Of course, this completion does not mean that it has been completely perfected to the point where it can be published in a journal, but it means that the deformed and twisted Xu-Weyl-Berry theorem can be used to calculate Betelgeuse.
This is two different things from publishing a paper. Publishing a paper is more troublesome than this, and there are many things that need to be perfected.
But I probably won’t have time to continue improving it today.
Thinking about it, Xu Chuan stuffed the corner of bread in his hand into his mouth. After sorting out the manuscript papers on the table, he picked up his cell 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 was given the green light by the higher authorities, formal procedures still need to be followed, but the review time will be compressed to the extreme.
If you apply for a normal topic, it will definitely be too late.
Ordinary project applications have time limits, and the general deadline for submitting applications is about one to two months.
There are many uncontrollable factors as to when the notification of project establishment will be issued. It may take anywhere from 3 to 6 months.
Therefore, under normal circumstances, the time from application to project approval is about three months.
As for his side, it cannot be compared with ordinary topics. The research topic related to the follow-up of the xu-weyl-berry theorem has been submitted before, and the higher-ups also gave the green light for rapid approval.
So in the past two days, he just had to cooperate with Fan Pengyue to set up the relevant projects, and then Nanyang University quickly transferred the 2.4 million project funds to the dedicated account.
When the funds arrive, the research on Betelgeuse can be officially started.
.......
After two or three days of struggling with my senior 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 the dedicated account in three days, and in a few days, various astronomical equipment used to observe Betelgeuse will also be vacant.
Everything went smoothly, and senior brother Fan Pengyue even helped find several doctoral students from the astronomy department to join the research and development team.
Of course, it's the hired kind.
However, for these doctoral students, they are willing to hire them. Not to mention the project subsidy, they have to participate even if it is a reverse payment.
The Department of Astronomy is well-known as an unpopular major at NTU, no, in the 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 astronomy majors were generally regarded as relatively "ideal" people, because it was not easy to find a job after graduating 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, geodesy, etc., as well as teaching and research work in some universities. The positions can be said to be rare.
After all, in China, those who are capable and capable of studying astronomy belong to major universities in the country. Capitalists will not throw money at this at all. This is obviously a matter of throwing money into it without any income.
There are people involved in the beheading business, but no one is losing money.
That is to say, an organization like the state can invest some funds every year to do these things.
Therefore, astronomy jobs are the kind where there are too many people and there is little food, and they need to be competed for.
If you can participate in a large-scale scientific research project while still a student, 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 he hired to have a meal together before the project started.
"Dear seniors and juniors, here's a toast to you, and I wish us happy cooperation in subsequent scientific research projects."
In the box, Xu Chuan stood up with a glass of beer and smiled and said to the seniors of the astronomy department in the box.
Whether at home or abroad, things like human relations and sophistication are unavoidable, but domestic human relations exchanges are more in-depth.
A simple meal can be exchanged for the full help of these doctoral fellows for the next twenty days. Even if he pays for the treat himself, it is worth it, not to mention that it can be reimbursed through scientific research funds.
"Honor the God of Sichuan."
"I wish Chuan Shen's research project success."
"come on."
"..."
Xu Chuan stood up and made a toast, and several PhD fellows from the Department of Astronomy also stood up quickly, holding disposable plastic cups and gulping down the beer in them.
"Don't be polite, everyone. It's time to eat and drink tonight. From tomorrow on, it's my time to trouble you."
Xu Chuan sat down with a smile. He was not very good at dealing with interpersonal relationships, but he could still handle things like treating guests to a meal.
"Hey, what's the trouble? Our astronomy department can participate in scientific research projects, which is something no one else can ask for."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "That's right, I am already a doctoral student. This is the first time I have participated in a scientific research project."
"Kawashen, is your project this time to observe and collect information about Betelgeuse?"
At the dinner table, perhaps because they were not facing their supervisor, the atmosphere was quite relaxed. After a few glasses of beer, several fellow doctoral students gradually relaxed a little.
Upon hearing the inquiry, Xu Chuan nodded and said, "Well, this project is actually a derivative study of the Weyl-berry conjecture."
"And Betelgeuse was quite suitable, so it became a research target."
"Betelgeuse, the one on the cantilever of Orion, is indeed a good research object, but 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. The main purpose is to use the xu-weyl-berry theorem to make an accurate judgment on Betelgeuse's size, diameter, and mass."
"Huh? Haven't the size and mass of Betelgeuse been measured long ago?"
"If I remember correctly, it is a red supergiant star with an m1-2 spectrum. It is located in the constellation Orion. Its radius is about 887 to 955 times that of the sun. It is about 640 to 724 light years away from the earth. It has an 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 about Betelgeuse.
Xu Chuan smiled and said: "But it's not accurate, isn't it? These are all estimates."
"For example, the mass of Betelgeuse has always been controversial. Some data show that its mass is only 14 to 15 solar masses, but some data believe that its mass reaches 18 to 19 solar masses, and some even reach 20 solar masses.
."
"Indeed, because the distance is too far, the estimate of its mass is not accurate, so the deviation is large."
Liu Xuan nodded, then reacted, looked at Xu Chuan in surprise, and asked: "Sichuan God, are you trying to measure its precise mass?"
Xu Chuan nodded.
After receiving confirmation, the doctoral student in the astronomy department looked at Xu Chuan like he was looking at a monster, and the other people in the room were in similar situations.
"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 student in front of me proved a world-class conjecture in his freshman year, and might win the Fields Medal two years later, the words that popped up on his lips were eventually replaced by 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 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 Ph.D. fellows from the astronomy department looked 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 far away in sight, somewhere you can't see, the sound of the drum reaches your ears.
Now, do you think you can tell the size and shape of the drum in the distance by hearing the sound of the drum with your ears?"
"impossible!"
"How to judge this?"
"Sichuan God, I'm afraid you have a good ear. You'd be damned if you could hear this."
As soon as this question came out, several doctoral students shook their heads and replied. Only Liu Xuan next to him asked curiously.
"Is it possible to do this using the theorem you proved before?"
Xu Chuan shook his head: "No, doing this is not my research result. In fact, as early as the last century, mathematicians could confirm the size and shape of the drum by judging the sound of the drum. It just requires
Just some conditions.”
"Distinguishing the drum shape by listening to the sound is a two-dimensional proof of Weyl-Berry's conjecture, and I extended the two-dimensional proof to high latitudes, so it can be used to judge the mass and volume of stars."
"You can think of the stars in the distant starry sky as a drum. The star's radiation waves, gravitational waves, space distortion and other information are the key points I use to judge its precise size, volume, and shape."
"Although it sounds miraculous, theoretically speaking, this can indeed be done, and this is what my research is about."
In the box, several fellow doctoral students looked at Xu Chuan blankly, still in disbelief.
In their concept, calculating the mass of a star is generally calculated through common methods in the literary world, such as the law of universal gravitation, gravitational red shift, and photometric calculation.
Although it is not very accurate to calculate the mass of stars in distant galaxies, there is no other way.
But now the freshman student in front of them told them that he had a better method that could accurately measure and calculate the mass of stars.
Is this so outrageous that he opened the door to outrageous things? Is this outrageous enough?
