Qin Ke said with a smile: "Yes, it's quite unlucky for Mr. Jiang to have us as two disciples. He spent most of his two years in college on mathematics, and finally went to graduate school with him, and even asked for leave all day long.

Participate in a mathematics report. But he will probably be happy next. Our main focus is N-S equations. At least during the day at school, our energy can be returned to his instruction in fluid mechanics. Except for the occasional visits to Qiuzhen Academy and Yan

Give a great lecture.”

Whether it is for his own interests, goals or systematic tasks, Qin Ke plans to put most of his thoughts back to the fluid mechanics and N-S equations of physics during the day. As for the night... that belongs to the team with Professor Kopet from Germany.

Due to the time difference, it is evening here and afternoon over there at the University of Munich, when scientific research is in full swing.

However, Professor Koppet's team is mainly responsible for improving theoretical derivation and experimental verification of the mathematical model deduction results of Qin Ke and Qin Ke. The latter often progresses slowly due to the schedule of key laboratories. This is a cross-border cooperation topic.

It would have been even more leisurely if Qin and Ke had not actively participated in the theoretical derivation and improvement part.

As for other topics in mathematics, such as Hodge's conjecture and the study of biological computational seed science (new desert sweet potatoes), Qin Ke plans to use his lunch break every day and his free time on weekends and holidays to complete them.

"Well." In order to keep out the cold, Ning Qingyun stomped her snow boots subconsciously and breathed: "We should really put our energy back into physics. I feel that I can't live up to Teacher Jiang's high expectations. I

With a vague intuition, he put us in the particularly critical 'Turbulence Group' in the 'Air Turbulence and Climate Prediction' research group, not just to train us, but in the hope that we could help him solve some difficult problems."

A dignified academician, but he wants to pin his hopes of solving big problems on two graduate students? Doesn’t it sound a bit funny?

Qin Ke nodded in agreement: "Indeed, the problem of turbulence is not in physics, but in mathematics. Not to mention the huge amount of calculations, especially the need to be extremely familiar with partial differential equations, and even proficient mathematicians to join in.

, in order to deepen the research and application of the Navier-Stokes equations. Teacher Jiang also said before that he wanted to ask Mr. Qiu to help, but Mr. Qiu’s main focus is on Qiuzhen Academy and he wants to focus on the development of the country.

Teacher Jiang can’t disturb his career in mathematics. It’s not surprising that he now puts his hope in us. Teacher Jiang probably can’t find anyone who is a math master better than the two of us.”

Qin Ke said it a bit arrogantly, but this is also the confidence of the Philippine Awards boss.

Ning Qingyun pursed her lips and chuckled, glanced at him, and did not call him an "arrogant man" as usual. She just sighed: "Teacher Jiang thinks of us too highly. The N-S equation is really difficult...

…I have been studying it for more than half a year, and I just feel that I have just entered the entry level, which is much more difficult than Goldbach’s conjecture.”

"If it's not difficult, how can it become a millennium conjecture related to both physics and mathematics?" Qin Ke reached out and brushed a few hairs around the girl's ears that were slightly messy due to the north wind, and said with a smile: "But the truth is often there.

In nature itself, you see, these few hairs of yours have already solved the N-S equation many times."

The north wind blowing the hair is of course also a fluid movement, and the special solution of the N-S equation based on fluid motion also appears again and again in the movement of nature. However, as humans, we cannot see this "N-S" with the naked eye.

It’s just the process of “application and solution of equations”.

But mathematicians have another way. They don't use their eyes, but use their brains, pens, and paper to restore it.

This is the greatness of mathematicians, and it also declares that mathematics is the basis of all laws of nature and the source of the foundation of all sciences.

Ning Qingyun has also studied the N-S equation for more than half a year. Hearing what Qin Ke said was interesting, he couldn't help but laugh.

The girl who was always afraid of the cold suddenly took her little hand out of Qin Ke's pocket, trotted forward a few steps, then stopped and turned back, blinking her beautiful eyes playfully: "Then I was so involved just now.

After thousands of times of solving the N-S equation, have you seen any truth?"

Ning Qingyun's hair was flying in the wind, and her pretty little face that was a little red from the cold under the pure white scarf actually added a bit of charm and cuteness. At this time, she stopped and turned around, with her hands behind her back, her expression was indescribable.

Delicate and charming, like a beautiful Japanese illustration.

Qin Ke felt that he really loved the girl in front of him. She not only had the wisdom and intelligence of a science girl, but also had the romance and innocence of a liberal arts girl, and she also maintained the unique playfulness and cuteness of a girl.

Qin Ke rushed over, hugged her slender waist, picked her up and spun her around a few times. Amidst the girl's exclamations, he hugged her tightly into his arms and said with a smile:

"What I saw was not only the truth, I also saw that the stars could speak, the stones would bloom, and you would always be by my side after passing through the wooden fence in summer and the wind and snow in winter."

Ning Qingyun's eyes glowed with confusion. She buried her frozen little face into Qin Ke's warm embrace and said slightly: "Why do I feel that since I took 'Literature Appreciation' and 'The Beauty of Chinese Studies' in my sophomore year?

'After taking the elective course, you will become better and better at speaking nice words."

Although the temperature outside was still very low, Ning Qingyun felt that her whole body was wrapped in a warm and sweet feeling.

"I'm just telling the truth. I feel that our lives are not wasted at all." Qin Ke said with a smile: "After all, the glory of life lies in the timely mutual love and warm embrace between a pair of lovers who are in love."

"Have you also read the book "Antony and Cleopatra"?" Ning Qingyun asked in surprise.

While going abroad a few days ago, Ning Qingyun took the time to read the newly bought Shakespeare's masterpiece "Antony and Cleopatra" on the way back. Whenever she was about to fall asleep, she gave the book to Qin Ke to help collect it.

I read it, but I didn't expect that he actually read it and remembered a sentence in it that he liked very much.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! This feeling of tacit understanding filled her heart with an intoxicating sweetness, and she even forgot about the howling north wind around her.

"Of course, I will be interested in the book you are reading," Qin Ke said confidently.

In fact, his interest in literature is very general. Except for the international classics for which the teacher in the elective course assigned him to write a review, he has no intention of reading any other literary books that exceed a hundred pages.

Rather than reading a hundred pages of literature, he would rather read a hundred mathematics or physics papers and documents.

Qin Ke also only briefly flipped through the 300-page masterpiece Ning Qingyun mentioned. However, when Ning Qingyun was reading, Qin Ke noticed that her slender little fingers were running over certain passages over and over again. It must have been

If she particularly liked the words, she would secretly write them down and read them out at the right time like this to create little surprises.

In order to prevent them from being forgotten after a long time, Qin Ke specially lip-synced these passages and let Shimmer record them in the "Xiao Baicai Strategy Manual" (electronic version), and secretly read them from time to time.

And he also has a little trick, that is, after observing what literary works Ning Qingyun reads, he can find those "Reading a famous book in 3 minutes/5 minutes" online to read quickly. This is equivalent to understanding the outline of the story, and is not afraid of interacting with it.

Ning Qingyun exposed the truth during the communication.

——Although he is now very close to Ning Qingyun, Qin Ke is still willing to put in these little thoughts to make this beloved girl feel happier. For this girl who gives everything to him and ties all his love to him

Qin Ke cherishes and treasures the girl in his body from the bottom of his heart.

After hearing Qin Ke's answer, Ning Qingyun felt particularly sweet. She stood on tiptoes, exposed her pink lips from the scarf, and kissed Qin Ke.

"Thank you, Qin Xiaoke, for always staying with me." The girl with a single ponytail had a blushing face, and her eyes were shy and blurry. She hugged Qin Ke's arm tightly, pressed her face against it, and continued to walk together.

OK.

Qin Ke was so excited by this sweet and fragrant kiss that if he wasn't afraid that the weather would be cold and Ning Qingyun would freeze if he stayed outside for a long time, he would definitely kiss her back hard.

However, when the north wind blew, Qin Ke felt energetic: "Jun'er, how about we set a small goal and solve this N-S equation within two years?"

"Two years?" Ning Qingyun was so surprised that she stopped again. Her beautiful eyes widened: "Crack the N-S equation in two years?"

If she remembered correctly, Qin Ke studied the Riemann Hypothesis for almost four years before solving it. It was not as difficult as the N-S equation of the Riemann Hypothesis. Qin Ke actually wanted to solve it within two years?

Even if she is with you, I'm afraid it will be difficult to do it, right?

Qin Ke was full of confidence: "We are all good at this field of partial differential equations. It has been almost two years, no more than two and a half years at most, and Mr. Qiu from Qiuzhen Academy is here, so we can really meet each other in the field of partial differential equations."

If you encounter any problem that we can't solve, you can also ask this expert for advice."

In fact, Qin Ke asked Mr. Qiu for advice just to make his two-year period not too scary.

Now he holds the first, middle and second parts of "Exploration and Detailed Explanation of Nonlinear Partial Differential Equations 'Navier-Stokes Equations'" and has completed "[Special Task] It's time to send out your message in the world of physics"

After "International Voice", he can still get the final chapter. By then, the N-S equation will no longer have any secrets in his eyes, so there is no need to ask others for advice.

The only pity is that his physics level is still at the professional level, which is equivalent to a lecturer with a doctoral degree, even though he often reads the "Exploration of Nonlinear Partial Differential Equations 'Navier-Stokes Equations'" in his mind

"Detailed Explanations", he can only understand about 70% of the content. Of course, he has almost completely understood the mathematics part. Even if he does not finish the chapter, it is not impossible for him to complete the mathematics part, but it will take one or two years.

time.

Only the physics part involves too much content and becomes more and more profound as you go to the back.

With his "professional level" physics level, many of the contents in the second chapter are difficult to understand. It is estimated that he needs to be at least upgraded to the "master level" to fully understand the above theory.

And physics is different from mathematics. Mathematics only requires your own thinking and pen and paper. As long as all the derivation processes do not make mistakes, the results must be correct. But physics is different. It cannot be separated from experiments and any physical theory.

All are inseparable from the final experimental verification. No matter how good Qin Ke is in mathematics, the conclusions he can derive in the future using his "computational physics" expertise will ultimately end in experiments.

Besides, just mastering theoretical knowledge always feels like "what you learn on paper is only superficial". If you want to truly understand and master it, you must conduct experimental verification.

This is also an important reason why Qin Ke wants to stay in the laboratory of Academician Jiang Weixian to learn and master experimental operations, become familiar with various experimental instruments and equipment, and become familiar with the preparation of experimental plans.

…

The two braved the cold wind and stepped up their pace, and soon arrived at Academician Jiang Lao's experimental building, but unexpectedly found that there were very few people inside. There was only one doctor named He Weiyuan in the "Air Turbulence and Climate Prediction" research group.

Live and stay behind.

When Qin Ke asked, he learned that Academician Jiang Weixian and most of the research team had gone to various places to investigate weather changes half a month ago to predict whether there would be extreme cold weather like last year's winter this year.

I won't be back until next week.

Qin Ke couldn't help complaining in his heart, Teacher Jiang, it's true, he even called him last week, and Teacher Jiang didn't mention this at all.

But on second thought, Jiang Weixian probably knew that they had just returned home and were very busy those days, and didn't want to disturb him and Ning Qingyun.

"Qin Xiaoke, what should we do? Do you want to do experiments here?" Ning Qingyun habitually asked Qin Ke's opinion.

Qin Ke thought for a while: "No more experiments, let's go to the data room and try to read all the data on the 'Air Turbulence and Climate Prediction' research group that Teacher Jiang has collected over the years within this week! He

Senior, can you open the door to the reference room?"

He Weiyuan, the doctoral student next to him who had just answered their questions, couldn't help but said: "Yes, yes, but, senior Qin Ke, our research group has at least thousands of volumes of materials..."

——Although Qin Ke and Ning Qingyun are already full researchers and distinguished professors in the Department of Mathematics, Academician Jiang Weixian has said that they are just new graduate students in this laboratory building, and others are only allowed to call them "

"Junior" and "Junior" are not allowed to be called "Professor".

There were thousands of books, but Qin Ke felt that the more, the better. He took a look at his physical level information.

Physical level: professional level, next level: master level, upgrade progress: 569/1000

There is still a long way to go before upgrading.

Academic points can only be accumulated through tasks, study, and scientific research. The main means of learning is to brush up on literature and papers.

Going to the reference room to read the research group's literature can not only increase academic points, but also allow the two of them to truly understand the development and achievements of the entire research group over the past ten years. In any case, it is a multi-purpose thing.

Qin Ke and Ning Qingyun, who were very motivated, started to work hard every day in the data room and read materials.

Being locked up in a small room and looking through a mountain of archives and documents is simply synonymous with boredom and depression in the eyes of others, but Qin and Ke enjoy it.

Thanks to "Dada K" and "Xian Zhuo" for the reward! I wish everyone a happy new year, all the best, and most importantly, good health and stay away from viruses!
