I really just want to be a scholar

Chapter 575 Graduating from a bachelor's degree, youth is so good!
Qin Ke first looked at his test paper, and saw that it read "Using Thermodynamics and Atmospheric Circulation to Establish an Experimental Model to Analyze the Causes of Excessive Rainfall in Extreme Weather".

The content of the test paper is also very simple, with only one paragraph: "The original data can be consulted through the school's electronic library, and at the same time, you can borrow the laboratory of Professor Hu Qingfeng from the School's Physics Department. You don't have to worry about all expenses. Time limit: two weeks."

Qin Ke couldn't help complaining in his heart, is it really an undergraduate level exam... Are you sure it's not a postgraduate level?
Although he is no stranger to doing projects now, especially the teachings of Professor Hu Qingfeng and Professor He Liangfu some time ago have made him familiar with the management process of the entire physics project, but now he is suddenly going to do physics independently. The topic, and it is not an easy and simple topic, it is a bit dumbfounded.

However, when the papers are in hand and the topic has been set, Qin Ke can only sigh. It is worthy of being an academician's exam. Others use pens to answer the questions. Academician Jiang directly gave a topic, even the source of the original data, venue and cost. solved.

Qin Ke glanced at Ning Qingyun's test paper next to him, and saw the same content.

It seems that although the exam arranged by Academician Jiang is a bit more difficult, it is not so outrageous that the two of them can complete a project separately, and they can still work together to complete it.

——Of course, the main reason should be that they don't want the two of them to spend too much time on this graduation exam.

Senior Academician Jiang Weixian watched the two of them look at each other with a slight smile on his lips.

He has no doubt that these two disciples have fully mastered the knowledge points of the [-] designated physics textbooks. In fact, he has a copy of all the curriculum schedules and final grades of these two disciples. For Qin Ke and Ning Qingyun His physical level and knowledge are already well known, so naturally he will not use ordinary exams to test the two of them.

According to his judgment, with Qin Ke and Ning Qingyun's physics level in fluid mechanics, it is not difficult to get a postgraduate master's degree.

The reason why Jiang Weixian came up with this project to test the two is to increase the opportunities for exercise, and to lay the foundation for the two to join his key research group.

His research laboratory is a national key research laboratory. There are more than a dozen researchers with senior professional titles, and dozens of associate researchers. If the graduate students in the school join in, they can only do the most basic odd jobs. Ph.D. Only postgraduates can barely work as research interns, and only postdoctoral students have the opportunity to work as assistant researchers.

Qin Ke and Ning Qingyun joined it as graduate students. If they want to skip doing odd jobs and go directly to internship with the class, they must show enough strength to convince the crowd.

This independent project is a good opportunity-this is actually part of a Navier-Stokes research group that studies atmospheric circulation problems.

If Qin Ke and Ning Qingyun can independently complete this project within two weeks on their own, it can basically prove that their strength is comparable to doctoral students, and they are qualified to be interns—although Qin Ke and Ning Qingyun The current job title is "Associate Researcher", and there are even rumors that this month they will be rated as "Researcher" at the professor level, but that is only in the direction of mathematics, and the two of them have not yet achieved the same dazzling results in physics as in mathematics, so The highest can only start as a research intern.

It can be said that in order to allow the two students to better embark on the road of scientific research, the old academician Jiang Weixian also took great pains.

"Okay, you can leave when you get the test questions. When you finish this project and write a thesis, please contact me to review the manuscript."

"Yes. Qingyun and I will work hard." Qin Ke and Ning Qingyun saluted Jiang Weixian before leaving.

……

During the summer vacation, it was difficult to see any students on the campus of Qingmu University. Most of the students embarked on the journey back home after the special report on the proof of Goldbach’s conjecture, which made the campus quiet—— ——Even the basic science class had a farewell meal for the two of them, but knowing that Qin Ke and Ning Qingyun still lived in the original dormitory and continued to stay in school for graduate studies, the sadness of parting in the basic science class eased a lot.

At this time, walking on the sunny school road, Ning Qingyun frowned slightly and said: "The subject that Mr. Jiang arranged seems to be quite difficult."

She doesn't think it's troublesome, in fact, she likes physics very much, and she is very happy to be able to exercise herself with such a subject.

The main reason is that she knows that Qin Ke is still concentrating on deriving the fifth set of expressions of the Riemann conjecture, and she is afraid that this relatively complicated experimental subject will distract Qin Ke's energy and eventually affect Qin Ke's competition for the Fields Medal.

Especially in early August, the two of them had to fly to the United States to win the Steele Award from the American Mathematical Society, and it took nearly ten days to go back and forth.

In this way, the time for Qin Ke to delve into Riemann's conjecture will be even shorter.

Qingmu University in midsummer is already a bit hot, and the two of them held hands, and there would be some tiny beads of sweat on the palms of their hands.

But no one wanted to let go of each other's hand. The separation some time ago made the intimacy between the two of them a bit stronger.

Qin Ke felt the softness and greasyness of the girl's little hands, and said with a smile: "It's okay, it's just a very simple small topic. As long as you get the original data, build a mathematical model and analyze it, you can roughly know the main cause. This is used as an experimental model for verification. It will not take much time."

Ning Qingjun pondered for a while, and suddenly suggested: "How about, leave this project to me alone. You can just focus on the Riemann conjecture. This project is a bit difficult, but in two weeks, I still have confidence of."

Qin Ke understood her thoughts, and couldn't help but reached out and rubbed her hair: "Fool, we had to go to class every day before, and there were still a few topics in hand, and it didn't delay me from researching the first four sets of expressions of Riemann's conjecture Is it? We don’t need to worry about the topic of computational seed science and new desert sweet potato for the time being. The “Topological Quantum Computing Project” cooperating with Professor Coppet will not have new feedback until the end of the month at the earliest. That is to say, the next dozen I have nothing else to worry about except the Riemann conjecture, and adding a small topic of atmospheric circulation is nothing at all."

"But..." Ning Qingyun still wanted to insist, Qin Ke stared at her pretty face, and said warmly: "Besides, if you stay in the laboratory alone, I stay in the study room alone, don't you think Is it particularly lonely and boring? At least in my eyes, without you, learning and scientific research have lost most of the fun."

Ning Qingyun's heart seemed to be hit by something, and it suddenly softened. The tenderness and affection rippling from Qin Ke's fingertips in the hair made her feel soft from being rubbed.

Qin Ke smiled warmly again: "Besides, compared to deriving the fifth set of expressions of Riemann's conjecture as soon as possible, I think it is much more interesting to walk slowly with you and see the beautiful scenery of the scientific research road. "

Qin Ke also thought about it. Although the Fields Medal is very good, it is an award judged by foreigners after all. There is no need to let one's study, scientific research and even life revolve around it.

Qin Ke didn't want to look back and find that he only saw the Fields Award in his life during the past six months.

He even wants to embed the bits and pieces of being with Ning Qingyun, as well as the sweetness and fulfillment of going hand in hand on the road of scientific research, into the depths of his memory, and finally pave out moving pictures of growing old together.

Besides, my strength is the "grandmaster level" certified by the system. With such strength, I will win the Fields Medal sooner or later.

Therefore, although Qin Ke still aimed to solve the Riemann conjecture and win the Fields Medal, he was no longer in a hurry, and did not put too much pressure on himself.He values ​​the present more than the future.

Listening to Qin Ke's emotional words, the girl's eyes were filled with scarlet shyness and sweetness, and a shy smile appeared on her pretty face, which was originally glowing with a faint healthy blush, but her heart beat faster and faster , The love for this boy in my heart is overflowing.

She bit her red lips lightly, looked around quietly, and suddenly opened her arms, hugged Qin Ke's neck tightly, and stood on tiptoe.

In the next instant, Qin Ke's lips were covered with a warm, fragrant and moist touch.

Qin Ke's heart also beat violently.

This normally shy girlfriend would always do such bold and exciting things when impulsive.

Qin Ke hugged the girl in his arms tightly, and accidentally saw the bright sunshine in his eyes, and couldn't help feeling in his heart, youth is so good, love is so good.

……

This "Excessive Rainfall Project" is not difficult to say, but it is not easy to say that it is easy. Qin Ke and Ning Qingyun spent nearly three days in the library, and artificial intelligence Shimmer assisted in selecting and sorting out the data. Only then did I find enough data, which also included some news about heavy rainstorms, as well as astronomical and meteorological data at that time.

In the eyes of others, these complicated data are simply irregular, but after Qin Ke and Ning Qingyun conducted several times of data screening and conversion into charts, they saw many traceable clues, some of which were not in these laws The special case is the "excess rainfall" that requires an explanation of the reason in the subject.

Excessive rainfall is often caused by extreme weather. The dynamic causes are diverse, the formation mechanism is complex, and the probability of occurrence is extremely low. If you want to analyze the main cause of it, you must find out which factors affect them, causing them to jump out of the conventional law, and finally Developed into "excess rainfall".

This originally required a lot of effort to list all possible factors, such as the interaction of multi-scale circulation systems leading to abnormally strong upward airflow, such as unique terrain factors, external environmental factors such as typhoons, and subtropical high pressure factors, monsoon climate, etc. .

But for Qin Ke, who holds the first, second, and second parts of "Exploration and Detailed Explanation of the Nonlinear Partial Differential Equation "Navier-Stokes Equation"" in his hand, it is simply like learning advanced mathematics to solve the problem in junior high school. It is as simple as a quadratic equation in one variable.

Qin Ke originally wanted to let Ning Qingjun start research on the NS equation, so he took the opportunity of this project to continuously instill relevant knowledge, theories and derivations in her, and cooperated with her to establish a set of effective formulas. mathematical model.

Five days later, a set of mathematical models code-named "circulation-thermal influence model" was established.This set of mathematical models is applicable to excess rainfall events with a total precipitation of more than 1000mm in recent decades. It uses detailed data to completely simulate the circulation evolution process and the corresponding spatio-temporal characteristics, and quantifies the thermal factors of climate change.

After the model was established, the two adopted the policy of "keep the value of a certain factor constant, and analyze the changes in rainfall in different extreme climates", and soon deduced a more critical factor: the proportion of factors affecting global warming 7 %, the influence factors of water vapor transport accounted for 16%, the influence factors of atmospheric stratification stability accounted for 17%, the influence factors of vertical upward movement and condensation latent heat feedback accounted for 21%...

In addition, human activities, especially the generation of urban agglomerations, will also have an impact on the climate, which will eventually lead to the birth of extreme climate at a certain probability.

After the mathematical model is completed, it is a more complex experimental model. It is necessary to use the existing equipment in Hu Qingfeng's laboratory to design an experiment that can verify the mathematical model.

Qin Ke and Ning Qingjun decided to use the quasi-geostrophic single-column simulation method (CQG method), which is based on the quasi-geostrophic vertical velocity equation (one of the sub-derivations of the NS equation) to simulate atmospheric circulation and thermal Dynamic interaction, and designed several sets of experiments for comparative verification.

The construction and operation of the entire experimental model were done by two people. Although it was a bit cumbersome, the two enjoyed it.

Professor Hu Qingfeng has also been here several times, and he stood by and observed with great interest. The more he looked at Lao Hu, the more surprised he became.

Because he found that the experimental model built by the two students was very targeted, at least judging from his professional point of view, it was completely correct, and it was of great reference value. Lao Hu wanted to call members of his project team to visit and study Later, he reluctantly endured it because he was afraid of disturbing the two people who were concentrating on the realization, but he had already made up his mind. Use it as a reference material for your research team to study and discuss.

In the end, it only took Qin Ke and Ning Qingyun eleven days to complete the entire project, and wrote a paper, which was handed over to Academician Jiang.

After reading it, Old Academician Jiang only said "yes", and asked the two to come to the door to take their graduation certificates and degree certificates.

"Okay, go back to the graduate department of the school's physics department to report after September, and I will arrange your courses and follow-up internships. As for the next vacation, you can enjoy it and follow me. I'm afraid you won't have this It's a long vacation." Jiang Weixian, an old academician, "bombarded" the two of them half-intimidatingly and half-jokingly, and then took out the article titled "Detailed Explanation of the Causes of Excessive Rainfall Under Extreme Weather", his eyes flashed The radiance of relief.

After casually writing an excellent evaluation of "full marks" in the evaluation of the graduation thesis of the two of them, he picked up the office phone: "I will send you a paper later, and you all have a look at it together, and the problem you have been having headaches has been solved. Who solved it? Qin Ke and Ning Qingyun. It took about eleven days in total, so-so, and passable. But you have to work harder, they will come to the laboratory in September, don't let them compare gone."

Hearing the commotion and exclamation from the other end of the phone, Senior Academician Jiang Weixian put down the phone in satisfaction.

……

After [-] days of busy work, they got their undergraduate degree certificates and physics degree certificates, which meant that Qin Ke and Ning Qingyun had officially graduated from their undergraduate courses. From this moment on, they were already graduate students. up.

After being free, Qin Ke and Ning Qingyun were not used to the ease of this free period.The schedule for returning to my hometown is set after returning from the United States in mid-August.

It was July 27th, and there were still nearly seven days before departure to the United States to receive the award. If it was all used for study and research, it seemed that the good weather and good vacation would be let down.

So Qin Ke waved his hand and decided to fulfill one of his wishes, by the way, to take a graduation trip with only two of them.

They took Ning Qingyun to a southern island and booked a small beach. During the day when the sun was strong, the two stayed in the shipwreck villa to do research. In the morning and evening, they changed into swimsuits and went to the shipwreck to play together and watch the sunrise. watch the sunset.

The two saw the magnificence and heroism of the ebb and flow, and also appreciated the beauty of the sea covered by the golden light of the sunset, and also experienced the changeable summer showers that come and stop as they say.

The laughter and happy silhouettes of the two of them for nearly five days were left on the beach. Finally, in early August, the two flew back to the capital, took a short rest, and then flew to the United States again.

　In the new month, continue to ask for monthly ticket recommendation tickets and full reservations, as well as character likes and chapter talks.Newly joined friends can join the group, there are many surprises.
