I really just want to be a scholar

Chapter 621 Shocked Professor Sreenivasan!

After Qin Ke and Ning Qingyun returned to Yuanzhou, as in previous years, they first organized employees of Lime Technology and Lime Education Foundation to have a New Year's dinner in advance.

Because there were unexpectedly many year-end awards, all employees were in high spirits, and there was an indescribable admiration for Qin Ke and Ning Qingyun, two famous mathematicians and scholars who have long been famous all over the world.

All of these made the atmosphere of the dinner party very good, full of lively laughter.After the dinner, Qin and Ke returned to Lvcuiying to live for one night—the assistant Fang Yongtang regularly arranged for the cleaning staff from the Lime Property Company to come to clean the house, so there was no need to worry about the accumulation of dust inside.

Afterwards, the two planned to visit and give condolences to Lime Lime Primary School, the first student aid project of the Lime Education Foundation.

After the completion of the primary school, it does not mean that the Lime Education Foundation will withdraw from the assistance. Each mountain village teacher will receive a special subsidy of 3000 yuan per month, and the primary school students will also receive food subsidies to ensure that they can drink a bottle of milk every day. In addition, the regular update, maintenance and procurement of playgrounds, teaching buildings, and teaching materials are not small expenses.

Fortunately, the number of directors of the Lime Student Foundation has doubled, and most of the recruits are personnel with accounting certificates and related experience, so that the operation of funds can be effectively monitored, audited, and calculated.

As for these financial matters, Secretary-General Huo Baoyan will not participate. The foundation's council headed by Shen Tieshan and Deng Hongguo will supervise and escort the whole process, and Qin Ke and the two don't need to bother.

But as the actual person in charge of the foundation, it is also necessary to visit the aid project every year, not only to understand the situation on the front line, to avoid being fooled by just reading the report, but also to meet those children and mountain village teachers You guys, be reassuring - after all, Qin Ke made a promise that as long as the mountain village teachers have worked for six years and performed well, they will be guaranteed to be adjusted to teach in elementary schools at the township level or even the district level.

For the hard-working mountain village teachers, economic subsidies alone are not enough. They must be given hope for future development in order to ensure that they can perform their duties as teachers with peace of mind and strive to cultivate children into talents.

Assistant Fang Yongtang drove for nearly three hours and sent the two of them to Stone Village.

Stone Village was also planted with the new type of seeds developed by Qin and Ke. The path in front of the village was also repaired by the Student Foundation and paved with cement, making the village gradually out of poverty. The primary school has also become the most popular place in several nearby villages.

The simple villagers and children cherish this hard-won primary school very much, and they come here every weekend to clean up, which keeps Shicun Qingning Primary School clean and tidy, which is in sharp contrast to the dirty and dilapidated scene of other village primary schools. Compared.

And elementary school students write letters to Qin Ke and Ning Qingyun every year. In these letters, which are often mixed with pinyin and some crooked handwriting, the children express their love for learning, and love Qin Ke and Ning Qing. Sister Yun's love and admiration for the future...

Because there are a lot of these letters, Qin and Ke are usually busy, so they can only find time to read them all. They seldom have time to reply to each child individually, and they often reply to the entire elementary school at a time based on the school as a unit.

It is said that every time they reply to a letter, the school will hold a meeting to read it out in public, while the children sit in a row with excitement and seriousness, listening to the reply on the radio.

Whenever they see the letters from these children and the photos sent by the school, Qin and Ke will feel warm in their hearts. They feel that their behavior of helping students is very meaningful, and they are more determined to continue the foundation forever. determination.

But today, although more and more people know about the relationship between Lime Technology and Qin Ke and Ning Qingyun on the Internet, the existence of the Qingning Student Aid Foundation and its funding projects are not widely spread on the Internet , not many people know about it.

This is what Qin Ke and Ning Qingyun are happy to see.

Since the establishment of the Lime Student Foundation three years ago, the two have kept a low profile in front of the media, never mentioned the foundation, and avoided being kidnapped by others because of excessive attention-after all, no matter what you do How wonderful, some people will always feel that it is unfair, such as why you only support these villages and not other villages, there are still many villages that need help, and so on.

What's more, the two of them are famous enough and their image is positive enough, there is no need to use the Lime Student Foundation to earn image points.

They just want to do the good deeds they want to do in peace, and do their best to help the children in impoverished mountain villages to change their fate through knowledge, and to make those old farmers who have spent their lives working hard on the land all their lives Can live a better life.

This is also their original intention and goal of changing the world with technological inventions.

And the higher-ups probably understood what the two of them were thinking, and greeted the media, which made the mainstream media dare not report on the Lime Student Foundation. Ning Qingyun's development will operate...

Back in Shitou Village, the old principal of Shitouqingning Elementary School is still sticking to his post, and Wu Zhu, a roommate from high school, also returned to the village after the winter vacation at the university.

After meeting the children one by one and giving them New Year's gifts—a new set of schoolbags and stationery for each of them—Qin Ke and Ning Qingyun, accompanied by the old principal, primary school teacher, Wu Zhu and student representatives, visited Shicun Lime elementary school and looked at the children's report cards.

Qin Ke noticed that there were two young fresh faces in the elementary school. They were normal graduates who volunteered to teach in the village for two years.

The new teacher naturally recognized Qin Ke and Ning Qingyun, two big celebrities, and they both looked a little excited and eager to share the same goals.

While conversing with them, Qin Ke remembered a very grand and even dreamy plan he had set up at the beginning - to develop a sufficiently powerful artificial intelligence, supplemented by domestic chips and the body of a robot, to act as a knowledge transfer agent. The responsibilities of mountain village teachers come, while human teachers only need to be responsible for ideological and psychological counseling, as well as fine work such as taking care of children, which can greatly reduce the demand for the number of mountain village teachers.

After all, the number of teachers who volunteer to teach like this is still too small, and they often leave after only one or two years of teaching. It is difficult to fundamentally solve the shortage of teachers in mountain villages.

If the function of artificial intelligence as a knowledge teacher can be realized, it will undoubtedly greatly alleviate the problem of lack of teachers in mountain villages. It can only be a mirror image.

In any case, Qin Ke was originally interested in artificial intelligence, chip technology, and even material technology. After completing the study and scientific research in physics, it is also a good choice to continue to strengthen scientific research in these three directions.

……

When Qin Ke and Ning Qingyun were visiting Shicun Qingning Primary School, in an office of New York University, School of Physics, Professor Sreenivasan was looking through the student papers in hand and giving comments.

Professor Sreenivasan is 65 years old this year. As an academician of the two academies of the United States and an authoritative person in the field of fluid mechanics in the United States, especially in the field of turbulence, he is still struggling in the front line of the scientific research field, but because of getting older, he lacks energy. Continued, has slowly shifted the focus to the training of students.

At this time, his assistant knocked on the door politely: "Professor Sreenivasan, there is a newly received review invitation in your mailbox, which is from "Physical Review Letters". Are you interested?"

"An invitation from PRL?" Professor Sreenivasan has cooperated with PRL several times, and he himself has published no less than ten papers on it, so he nodded and said, "Okay, you can print it out for me."

When I am old, although I can wear reading glasses, staring at the computer screen all day still makes the old professor feel dry eyes, and he is still used to reading paper papers.

The assistant quickly finished printing and handed over three pages of double-sided printing.

PRL papers are often not very long, which is why Professor Sreenivasan is willing to put down his work and give priority to review invitations.

"Study on Large-Scale Circulation Shape and Kinetic Energy Variation Characteristics Using NS Equation"? I haven't seen a large-scale paper on turbulent flow for a long time."

Turbulence can be divided into large scale, medium scale and small scale. The so-called scale mainly refers to the range of influence in the cascade process of turbulent kinetic energy. A simple explanation of the differences and connections between the three is:
Large-scale turbulence is like a large storage battery, which continuously obtains energy from the outside and outputs it to mesoscale turbulence, and mesoscale turbulence outputs energy to small-scale turbulence. The larger the Reynolds number of the flow, the larger the energy storage and the smaller energy consumption The larger the inertia area between.

Professor Sreenivasan's main research direction is the small scale of turbulence, but he is no stranger to large scale and mesoscale, and can even be said to be equally proficient.

In recent decades, many people have studied the circulation, but mainly through observational data, theoretical derivation, and experimental simulation. It is the first time to study the characteristics of large-scale circulation morphology changes through the NS equation.

Professor Sreenivasan raised his interest. At least the papers that have been re-examined by PRL and entered the peer review process must be of a considerable standard.

Moreover, the assistant also printed the text of the email, which made Professor Srenivasan feel a little interesting.

Because it is stated above, please ask Professor Sreenivasan to review the conclusion part at the end of the second page, and the following physics part.

This is the first time for Professor Sreenivasan to see such a strange review invitation. How could the review experts only review part of the paper?Then how to write the audit results?Could it be that "My audit results are only responsible for the last part of the second page and the physical part that follows"?
What made him most curious was, according to the email, aren't the first two pages physical content?
Professor Sreenivasan put down the A4 paper with the printed text of the email, picked up the three printed manuscripts and carefully looked through them. Just like the editor-in-charge Sullivan, he was also shocked by the complex mathematical derivation at the beginning up.

Are you sure this isn't a math paper?
"No wonder PRL said that I don't need to review the content of the first two pages... I really can't review it." Professor Sreenivasan couldn't help laughing at himself.

After studying fluid mechanics and turbulence for a lifetime, it was the first time that I had a related paper that made me hit a wall at the beginning.

He continued to read the text description below.

Ok?Professor Sreenivasan sat up straight, looking more and more focused.

Now the turbulent kinetic energy is basically contained in the large-scale and mesoscale circulation, but how to dissipate the kinetic energy contained in the large-scale and mesoscale circulation to drive turbulent mixing is still an unsolved mystery in the physics community.

But in this paper, through a series of exquisite simulation experiments, the author proves that the symmetric instability between turbulence scales is one of the important ways to effectively realize the energy forward cascade, and points out that the large-scale circulation-mesoscale vortex —Sub-mesoscale process—Energy cascade dissipation between small-scale turbulence can induce strong turbulent mixing.

This is a new conclusion that the industry has never discovered!

Once confirmed, it will have important reference value for coarse-resolution climate model simulations, and can also be applied to climate change and its accurate prediction.If the study of El Niño is used, the relationship between the different El Niño states of the ocean will be analyzed from a new perspective, which will help to further understand the El Niño phenomenon!
What surprised Professor Sreenivasan the most was that these conclusions were not obtained through observation, but through mathematical derivation, based on the NS equation!The simulation experiment part of the paper is just a verification of the results of these mathematical deduction.

Even though the world knows that physics is inseparable from mathematics, and turbulence is even more inseparable from mathematics, no one has ever been able to deduce the characteristics of large-scale circulation shape changes and the kinetic energy dissipation changes behind them so accurately through mathematics!

Professor Sreenivasan was stunned for a while before he came back to his senses, and hurriedly looked at the author of the paper.

"Qin Ke, Ning Qingyun? The latest Fields Medal winner?" Professor Srenivasan couldn't sit still. He couldn't understand the mathematical derivation on the first two pages, but the two Philippine award magnates joined forces to attack , presumably the probability of error is very low.

He decided to personally use real data to verify this conclusion that has been verified by both mathematics and simulation experiments.

He called his assistant to come in: "Wendy, contact the National Weather Service immediately and ask them to provide the circulation observation data of the equatorial ocean thermocline in recent years. I know they have it. Then contact the School of Mathematics and ask them to send a An analysis expert will assist me with a data analysis, and help me apply for the school’s supercomputing resources.”

As an academician of the American Academy of Sciences and the Academy of Engineering, Professor Sreenivasan indeed has such qualifications. He applied to the National Weather Service for observation data and asked the School of Mathematics of the same school to send someone to assist.

As for applying for the use of supercomputers, it is even easier.

Professor Sreenivasan's academic status in the field of physics is really good, and there is no concept of Spring Festival in the United States, and he is still working normally. In less than a day, Professor Srenivasan directed his doctoral students, and Two associate professors sent by the School of Mathematics to conduct experimental verification together.

However, due to the large amount of data, it is estimated that the entire verification process will take about five days.

For this reason, Professor Sreenivasan asked his assistant to reply to PRL's email first.

"Five days later, I will give you a clear answer."

……

At the same time, Professor Tao from the University of California had put down his pen and rubbed his sore forehead, but his eyes were shining with excitement.

"Qin Ke, Ning Qingyun, you two are amazing, you two always bring me surprises, I am looking forward to the day when you can solve the mystery of the NS equation, just like you solved the mystery of the hail conjecture back then. "

Both of these are topics that Professor Tao has been interested in and put a lot of energy into, and has achieved world-shaking results. Unfortunately, he thought he could not go any further, so he stopped researching and turned to other directions of interest.

Now that the Hail conjecture has been solved by Qin Ke and Ning Qingyun, only the NS equation is left.

Professor Tao opened the mailbox and wrote in a reply to PRL: "As far as the mathematics part I reviewed, it is flawless and perfect, just like their previous papers. If you were a mathematics journal, I would even think that this It is an excellent paper that should be awarded 'Editors' Suggestion' and placed on the journal's homepage as a highlight paper (Highlights) for special introduction!"
