I really just want to be a scholar

Chapter 390 New Developments in Fluid Mechanics Papers
The news that Qin Ke will go to Princeton University to participate in the academic report conference at the end of the year has not spread. Only the senior management of the school and the leading professors of the two departments of mathematics and physics know about it.

The school attaches great importance to it. This is the first time that Qingmu University has given an academic report at such a high-level world-class mathematics conference. It is also related to whether Qin Ke and his academic achievements can be generally recognized by the international mathematics community. It can be said to have a far-reaching impact.

Vice President Gu personally invited five senior professors from the Department of Mathematics, including Professor Tian Jianlan, to simulate the questioning session of the academic report.

The entire academic report is divided into two parts: report and question.Qin Ke only has 30 minutes for the report, and requires clear focus, well-organized, and self-consistent logic. This part is not a big problem. The most difficult part is the 15-minute questioning session. Qin Ke needs to answer questions from mathematics experts from all over the world.

If you can’t answer one question, you will be questioned whether the twin prime number conjecture was proved by yourself, and you may even be suspected that there are loopholes in the proof process and it is not a perfect proof. Then there will be a follow-up “patch” provided by others. The halo of great academic achievement.

So what Professor Tian and others did was to "prick" as much as possible and "discover" all the details that might be asked, so that Qin Ke could fight a prepared battle.

Qin Ke knew that this was the school's good intentions and a rare opportunity, so he didn't proudly say "my argument is fine, and you don't need to ask questions", but seriously took the time to cooperate.

His attitude made several professors and even the school leaders appreciate it very much. Even Professor Tian Jianlan, who has never been very boastful, showed a faint smile for the first time after finishing the mock question, and said: "This kid is very good. "

Qingmu University breathed a sigh of relief at the results of the simulated questioning. After the school found a professional company to design the "academic exhibition board", it asked Qin Ke if he needed some PPT experts to help.

Qin Ke declined this time. The PPT of the mathematics report meeting does not need gorgeous effects, just dry goods.

Because of the limited time for the report, it is impossible for him to elaborate on the entire demonstration process, so the PPT is mainly prepared around the proof ideas and core difficulties and key points.

The careful Ning Qingyun helped Qin Ke a lot in this aspect. She has fully understood Qin Ke's thesis, and it would not take too much effort to arrange the content of the PPT. Moreover, the girl is clever and handy, and the PPT she made is detailed and layered. Layer by layer, almost no second modification by Qin Ke.

After sending the prepared PPT and academic display board PSD files to the mailbox of Princeton University's conference affairs team in advance, Qin Ke basically didn't have to spend time and energy on preparing academic reports.

Compared with preparing for the Princeton academic report, the three fluid mechanics papers required by the system were more troublesome than Qin Ke imagined.

For more than a month, in addition to his normal study and delving into Polignac's conjecture, he spent nearly [-]% of his free time writing these three papers.

Computational fluid dynamics is inseparable from the "Navier-Stokes equation". As far as the theoretical analysis part is concerned, Qin Ke, who has three S-level knowledge in hand, has no pressure. The difficulty lies in how to establish a mathematical model based on actual problems and data. Model, construction calculation method.

Physics is a practical subject, and its greatest significance is to describe and analyze real phenomena and solve real problems.

If you want to publish a paper in a top international journal, you must be creative, more profound and have practical theoretical value. Even computational fluid dynamics cannot do without the analysis and refinement of real experimental data.

Qin Ke repeatedly delved into the three S-level knowledge related to the NS equation, and looked for several graduate tutors and professors in the Department of Physics, asking if there were any topics related to fluid mechanics.

The time was so busy and fulfilling, because the distance was too far, he couldn't fly back to celebrate his younger sister Qin Xiaoke's 15th birthday, so he and Ning Qingyun bought a pair of beautiful crystal bracelets for the little girl to send. go back.

Another important thing is that Zhou Shutao, a professional manager, called. An international publishing house called and wanted to buy out the full-language copyright of the high school chapter of "Little Cat Lemon and Puppy Keke's Wonderful Mathematical Journey" for 80 million. Ke refused without hesitation. The news of this price would certainly shock the publishing industry in the entire Xia Kingdom, but it was considered a cheap sale for Qin Ke.

He estimated that the final net profit generated by this set of teaching aids would be at least over [-] million.

"I also think the price is too low, okay, don't worry, we don't accept this kind of buyout, we only accept the royalties." Zhou Shutao was originally not willing to buy out the sale, but the amount was too large, so he had to ask Qin Ke about it Just the opinion of the big boss.

There is still a follow-up to this matter. It is said that the large international publishing house was very dissatisfied with Qin Ke's "arrogance" and left in a huff.A few days later, I heard that another rival publishing house was willing to pay 5000 million yuan and 20% of the selling price royalties just for the copyright fees of ten foreign languages ​​such as English, French, German, Italian, etc. determined by the publishing house), and hastily negotiated with "Lime Technology" to increase the buyout amount to 1 million.

Zhou Shutao still refused, and chose another publishing house. In the end, this set of high school teaching supplementary materials was well received and sought after internationally, and directly entered the top [-] bestsellers in the world.

This is simply a miracle for a set of teaching aids, comparable to "Poor Dad, Rich Dad" and "The Little Prince", and it also made "Lime Technology" and the contracted publishing house a lot of money. As for that The large international publishing house that everyone insists on buying out is so regretful that its intestines are green.

These are all things to talk about later.

Qin Ke's thesis on fluid mechanics made new progress on December 12. Professor Hu Qingfeng, who taught the freshman physics and mechanics course, said that he had related topics.

He smiled and said, "Qin Ke, isn't your teacher, academician Jiang Weixian, who is best at fluid mechanics? You are looking for a porcelain bowl with a golden bowl in your arms."

Of course, Qin Ke also knows this, but Academician Jiang is usually very busy, and the topics are very advanced national high-tech, Qin Ke still has self-knowledge, and it is difficult for his undergraduate-level physics level to play a role in it. And Jiang Weixian also said that unless he passed his assessment, Qin Ke and Ning Qingyun would not be able to participate in his project.

After Qin Ke briefly explained a few sentences, the fat middle-aged Professor Hu Qingfeng with a chubby face was delighted: "Originally, the meaning of the school now is that everything should focus on preparing for the Princeton academic report, but if you really To delve into computational fluid dynamics, I happen to have a secondary settling tank project for an urban sewage treatment plant, in which CFD (computational fluid dynamics) models are used to analyze the distribution of liquid and solid phases, and the ability to solve mathematical nonlinear partial differential equations is required Very high, the graduate students under me have spent two months and have not been able to solve this bottleneck, I also want to ask the professors from the Department of Mathematics to assist, if you have free time, it would be best to help analyze and process this part of the data.”

The implication is that Qin Ke has been regarded as a professor level.

Professor Hu added: "In terms of time, I don't ask too much, as long as it can be done before January 1 next year, how about it?"

"Okay, I'll try." Qin Ke took out his mobile phone and looked at the schedule. Today is Saturday, December 12. Princeton's academic report will start after the Christmas holiday, that is, December 18, and will end on January 12. At the end of the day, I worked hard and calculated that I would have nearly three weeks to solve Professor Hu's problem, so I readily agreed.

Professor Hu smiled and said, "I'll take you to my graduate student to ask for data. Qin Ke, if you can help me solve this problem, there will be no need to attend the 'Mechanics I' of this semester and the 'Mechanics II' of the next semester." , I'll give you full marks."

Now Qin Ke is most famous for his mathematical talent and level of number theory and partial differential equations. On the contrary, he has no outstanding achievements in physics. However, if he can even solve the advanced problems of computational fluid dynamics, then there is really no need Waste of time taking courses in basic mechanics.

Qin Ke's evaluation as a professor in the future can almost be said to be a certainty, not only the students, but also many faculty members who want to deal with him in advance.Professor Hu is flexible, so he naturally wants to take this opportunity to get closer to Qin Ke.

Besides, he really needs someone to help solve this problem.

Qin Ke went to the sewage treatment laboratory with Professor Hu to copy the data, and then visited it under the guidance and introduction of Professor Hu himself.

Professor Hu's subject is mainly to improve the sewage treatment efficiency of urban sewage treatment plants and reduce energy consumption. It is the hope of a large domestic listed company to tackle technological problems. In the modern era when environmental protection and carbon neutrality are getting more and more attention, this subject The results are far-reaching.

The part Qin Ke is responsible for is only a small part of the secondary sedimentation tank, but it is directly related to the follow-up improvement effect of the secondary sedimentation tank, which is the key in this link.

Listening to Professor Hu's explanation, Qin Ke was a little excited. After all, his favorite scientific research is the direction that can improve the future life of human beings.

After getting the data, Qin Ke returned to the "Xiaowo No. [-]" self-study room. Ning Qingyun hadn't come back yet, and she was dragged by her roommates to go shopping.Girls want to get closer and build friendship. The most efficient way is naturally to go shopping and eat food together.

Qin Ke never wanted to tie Ning Qingyun by his side to become his vassal, and often encouraged her to participate in group activities in the dormitory. Ning Qingyun's going out this time can be regarded as Qin Ke's request.

Qin Ke turned on the laptop and copied the experimental data from the USB flash drive to the computer.

The amount of this part of the data is a bit exaggerated. Nearly two hundred pages of raw data are disorganized and irregular, but Qin Ke took a closer look and finally saw some clues.

"This part is the data of the turbulent flow problem. The fluid velocity in the secondary sedimentation tank is relatively low, which can be regarded as an incompressible Newtonian flow..." Qin Ke is no stranger to turbulent flow. He took out the draft paper and started to calculate.

　Thank you for your monthly ticket recommendation tickets. Today's busy work is basically over, and the second update will resume tomorrow, and we will strive for two weeks on Monday.

　　Thank you everyone!
