I really just want to be a scholar

Chapter 463 Using Mathematics to Deduce Fluid Mechanics Formulas?

Hearing Academician Wen Yuanping ask Qin Ke how he did it, everyone present looked curiously at him.

Qin Ke's performance during the day was too "supernatural", completely beyond everyone's imagination, even though they had been discussing it afterwards, they could not reach a reasonable result.

But what is certain is that Qin Ke must have done it after extremely complicated calculations, and it was also because of this that he was so tired that he fell asleep directly.

Qin Ke thought for a while, then met everyone's gaze and said: "Actually, this is a coincidence, because my teacher, Academician Jiang Weixian, is best at fluid mechanics, and I am most interested in this area of ​​knowledge. Professor Hu Qingfeng in the school has done two topics in fluid mechanics."

Professor Duan said with a smile: "I heard Lao Hu said this. He was full of praise when he mentioned the mathematical model you helped build."

"Actually, Professor Hu won the award, and I am even more grateful to him. It is precisely because I have the honor to participate in Professor Hu's project that I have a deeper understanding of fluid mechanics. This time I came to Professor Duan's laboratory, and I was fortunate enough to study at the Institute of Mathematics. The huge and complex mathematical model has benefited me a lot, combined with mathematical methods, I have figured out a lot of calculations related to fluid mechanics."

"Calculation?" Academician Wen Yuanping is also a great expert in physics, but he does not specialize in fluid mechanics. He was surprised: "You mean, you have deduced some new calculation formulas through the study of fluid mechanics in physics. ?”

"Yes." Qin Ke has long wanted to show his strength in fluid mechanics slowly, so that in the future he can confidently present the three S-level knowledge "Nonlinear Partial Differential Equations" Navier-Stoke This is the best opportunity right now.

He asked, "Do you have a pen and paper?"

"Yes." Qi Zhicong was beside him, and quickly took out a small notebook and pen from his backpack.

Qin Ke took it, and wrote while talking: "These calculations of mine are basically improved from the existing formulas and the experience in the mathematical model. I will write them out one by one, and then prove it. For example, the first One is the evolution of the total flow Bernoulli equation, flow Q=△h*K(z1+p1/pg+a1v1^2/2g+hw)^1/2..."

Qin Ke eloquently wrote more than 30 pages, involving the description and proof of nine extremely important turbulence calculation formulas.

The general solution of the "Navier-Stokes equation" involves too many aspects, and mathematics and physics have half and half.Now Qin Ke has not fully understood the first, middle and last three articles of "Exploration and Detailed Explanation of the Nonlinear Partial Differential Equation "Navier-Stokes Equation"", but he has understood more than [-]% of the mathematics part, and the physics part I also understand [-]% of it, and I can be regarded as a big expert in this field.

At this time, Qin Ke wrote some of the content that he had fully understood, so it was naturally effortless.

Almost everyone present has deep research in fluid mechanics, and the more you look at it, the brighter your eyes are, especially Professor Duan Yonggong, whose attainments in this area are ranked in the top ten in the country, and he tried his best to control the facial expressions. Shocked expression, but more than once in my heart I am overwhelmed, calling "Wizards of the World"!
These nine turbulence calculations include not only the conservation of momentum and the change of the pressure surface, but also the estimation of the flow velocity, and even the prediction of the vortex of the water flow!

Once it is expressed and applied through mathematical modeling, it will have an inestimable role and far-reaching significance in analyzing the overall stress of the dam and improving its structure in the future!

In particular, Qin Ke's calculations are all based on mathematical theory, deduced from the original physical fluid mechanics formula, but they are more advanced, more accurate and practical.

Although it is said that "mathematics is the only language that can describe the universe", there is also a special subject "mathematical physics" that describes physics in mathematical language, but there are absolutely not many people who use mathematical methods to derive physical formulas like Qin Ke A mathematician or a physicist can do it!
The more Professor Duan read, the more he lost his mind and became more excited. When he saw the seventh page of No.20, he finally couldn't help but praise: "Amazing!"

In fact, these nine formulas are very complicated, and the shortest formula has more than 60 characters. There are many parameters in it, and they are interrelated. To figure out these nine formulas requires a very solid mathematical and physical level. Qin Ke wrote here , only Professor Duan and Academician Wen Yuanping could keep up, and the rest, including Qi Zhicong, were already in a state of ignorance.

Ning Qingyun came back after heating up the food. Seeing the crowd surrounding Qin Ke, she didn't squeeze past. She just hugged the lunch box and stared at Qin Ke's focused expression from outside the crowd. Her eyes were soft and indescribable. Adoration and admiration.

What she likes to see most is this kind of Qin Ke, who obviously only holds a pen in his hand, but has a kind of self-confidence and momentum that dominates the world, which makes people unconsciously admire and admire him.

After writing the last step, Qin Ke closed his pen and sighed with some regret:

"The above nine calculation formulas are the results of my research these days. I also use them to calculate the force of the embankment through mental arithmetic, so as to judge which flood outlets should be opened and closed. I am ashamed to say that I was not very proficient at the beginning. The calculations were a bit wrong, which increased the slope of the embankment by about 1 degree."

The audience was silent, and everyone looked at Qin Ke with inexplicable respect, and the admiration in the eyes of Professor Duan and Academician Wen Yuanping couldn't be concealed.

In the end, it was Professor Duan who broke the silence and praised: "Qin Ke, if you are so modest, I'm afraid it will embarrass Xiao Qi and the others. With your nine formulas alone, you can become a regular professor of fluid mechanics in any university." Professors are qualified enough. It is the first time in my life that I can use mathematics to derive physical formulas to such an extent. It is amazing, really amazing!"

Academician Wen Yuanping also had a satisfied smile on his face: "Qin Ke, when I saw you today, I realized that you are even more genius than you Uncle Yang said. Not bad, the gate of our Xia Ke Academy is always open for you So, whether it is the Institute of Mathematics or the Institute of Physics, you are welcome to join. Whenever you want to join us, just call us, and I can make a statement, and I will try to get you a senior researcher treatment. "

In fact, he also knew that Qin Ke had an old academician Jiang Weixian as his teacher, and he didn't have to worry about top-level subjects at all, so he might not think highly of Xia Ke Academy.

Qin Ke hurriedly said: "Thank you, Uncle Wen and Professor Duan, for your compliments. I just figured out some formulas, which are nothing. In terms of practical experience, there is still a big gap between the seniors present here. I want to continue to follow when I have the opportunity." Learn from seniors."

What he said was the truth, he did already have a professional level in theory, and with S-level knowledge in his hands, his level in fluid mechanics had reached the master level.

But this is all at the theoretical level. When it comes to practice and applying what he has learned, he still has too much to learn. At least for now, if he is asked to independently design a small breakwater, he can't do it because it involves too much subject.

Physics is a broad and profound subject. Different from purely theoretical mathematics, physics needs to go a long way from theory to compound application.And this process of turning theory into practice cannot be achieved by systematically transferring knowledge. Qin Ke must rely on one topic and one scientific research project to accumulate enough experience, so that he can truly stand on his own and establish And manage your own research laboratory.

Seeing that Qin Ke was not arrogant or impetuous, and did not show off his complacent expression, everyone sighed and fell in love with him.

Professor Duan saw that Ning Qingyun was still holding the lunch box, and knowing that Qin Ke hadn't eaten yet, he took everyone to leave, and said that he would come to entertain Qin Ke tomorrow to thank him.

Academician Wen Yuanping also encouraged Qin Ke to guard against arrogance and impetuosity, and continue to work hard. He also left a very imaginative sentence: "Work hard, and try to give you a chance to vote for me before I retire. ticket."

What chance does Academician Wen Yuanping have to vote for Qin Ke?Naturally, it was the time for the selection of academicians.One of the important responsibilities of the Academy of Sciences is to co-opt academicians of the Faculty. This is a high expectation for Qin Ke!

Everyone envied and sighed in their hearts, but they also knew that they were not jealous. At least after seeing Qin Ke's talent and strength in mathematics and physics, they could only look forward to sighing.

And ah... Although this experiment accident will not be made public due to various reasons, it will definitely spread within the Xia Ke Academy, and Qin Ke's role in turning the tide will be widely known.

In a few days, when others mention Qin Ke, they will add the evaluation of "fluid mechanics genius" after "mathematical genius".

……

After Qin Ke finished his "dinner", Ning Qingyun wanted to rush to wash the lunch box again, but Qin Ke saw that the girl could hardly hide her tiredness and sleepiness, so how could he let her do these things again, so he pressed her on the bed and "forced" She slept and ran to the bathroom to wash the lunch box by herself.

It was almost two o'clock in the morning. Of course, it was impossible to go home to rest. The rest room in this infirmary was in good condition. There were still two beds, and the quilts were all new, but of course Qin Ke would not run away. Going to sleep on another bed, he turned off the light and unceremoniously got back into the original bed.Ning Qingjun in the bed was still not asleep, and shrank to the side in embarrassment.

Obviously, being so close to Qin Ke in such an unfamiliar and "unsafe" environment made Ning Qingyun feel particularly embarrassed, for fear of being seen by the doctor who will be patrolling tomorrow morning.

Qin Ke's eyes can see at night, so he can clearly see that Ning Qingyun's pretty face is flushed with blush. He likes to see his little cabbage so shy.

Obviously the two of them are already extremely close, but the shyness in Ning Qingyun's bones has not changed much, which makes Qin Ke's many new ideas fail to come true.

Qin Ke feels that there is a long way to go, but teasing such a shy girl is also a pleasure. Seeing her blushing and retreating to the bottom line will always give Qin Ke an inexplicable sense of accomplishment.

Of course, in order for Ning Qingyun to rest at ease, Qin Ke still jumped out of bed, went to lock the door of the lounge, drew the curtains by the way, then kissed Ning Qingyun's little face, and said softly: "Okay." Now, sleep at ease, no one will disturb you, and no stranger will see your sleeping face. Your sleeping face is so cute, only I have the right to see it, and no one else has a chance. "

"Overbearing..." Ning Qingyun glared at him shyly, after all, obediently and obediently, she slipped into his arms and closed her eyes.

"Qin Xiaoke..."

The girl with a coquettish nasal voice is very cute in the dark.

"Ok?"

"I can't sleep in this strange environment, can you sing me a nursery rhyme?" The girl's voice was cute and charming.

Qin Ke wanted to laugh a little, Ning Qingyun rarely had such a childish side, which reminded him of Qin Xiaoke unconsciously.

"Of course it's no problem." Qin Ke hugged Ning Qingyun tightly, sniffed the faint and touching fragrance of lime on the girl he loved, and sang a nursery rhyme softly.

After a while, Ning Qingyun fell asleep peacefully, with a sweet and charming smile on her lips.

Qin Ke had slept for so long, so naturally he didn't feel sleepy. In order not to disturb Ning Qingyun's sleep, although he was full of warmth, he didn't dare to move.

After thinking about it, Qin Ke simply took out his phone to have a look.

It was still Qin Xiaoke who sent the most messages on WeChat.

"Brother, there are a lot of papers today, and I feel like I'm going to die. Xiao Min is also complaining. By the way, what kind of laboratory are you and Sister Ning having fun in? I talked to Sister Ning, but she didn't answer me. "

"Woo... You and Sister Ning haven't responded to my messages all day, so you won't give me tutoring at night?"

"Brother, Sister Ning said that you were tired and fell asleep. She will give me tutoring tonight. What's wrong with you?"

"Brother, although sister Ning speaks very well, I always feel that I can understand better if you give me tutoring."

"Brother, brother, are you awake?"

The latest message came just after midnight.

This little girl stayed up late again.

Qin Ke shook his head, and replied: "Your sister Ning and I are very busy today. I just woke up, but your sister Ning fell asleep."

Qin Xiaoke is going to take the senior high school entrance examination in June. Although the little girl wants to take the art student route, and Qin Ke also greeted Principal Wen of Yingyuan Private High School, no matter how poor Qin Xiaoke's high school entrance examination results are, he can enter Yingyuan High School to study , but Qin Ke still felt that Qin Xiaoke could not be allowed to enter Yingyuan High School with a low grade, especially since he also had such a powerful weapon as "Thinking Resonance", which could greatly improve Qin Xiaoke's efficiency in listening to his own explanations.

So for more than a month, as long as Qin Ke has free time, he will spend about an hour every night to tutor Qin Xiaoke with homework through video chat. Sometimes he really can't spare the time, so he asks Ning Qingyun to help.

With his current level, even the liberal arts in junior high school can be explained in simple terms, let alone science.

And with the help of "thinking resonance", Qin Xiaoke's learning efficiency has indeed taken a qualitative leap. Although it is not as exaggerated as Ning Qingyun's ability to comprehend it after listening to it once, but it is basically as long as Qin Ke speaks it once, he can remember and understand all content.

Qin Ke estimates that "thinking resonance" can play a 90%-100% role in Qin Xiaoke's body. It's no wonder that this little girl has been attached to him since she was a child. In terms of intimacy and trust, I'm afraid it's only better than having a skin-to-skin relationship. Ning Qingyun is slightly inferior.

Thanks to this, Qin Xiaoke's grades have improved by leaps and bounds, and her science grades have risen to the top line. In the recent mock exam, her grades have been ranked in the top [-] of her grade, especially in science, she can be ranked in the top [-] of her grade.

Qin Ke reckoned that it was not impossible for Qin Xiaoke to be in the top ten of the whole class when it came time for the senior high school entrance examination.

The message was sent, but Qin Xiaoke didn't reply, probably fell asleep.

Qin Ke didn't care either. After replying to the message to be replied in WeChat, he closed his eyes and meditated, thinking about writing the nine calculation formulas into a paper. It's just that part of the experimental data needs to apply for authorization from Professor Duan, which is probably not a big problem.

In this way, his three papers on fluid mechanics are considered complete.

Next, submit the manuscript to the core journals in China, and when it is published, the task of the system will be considered complete.

After finishing the physics thesis, it was time for the finals of the Qiu competition.

This only requires an interview, and it doesn't take much time to prepare. Well, it's almost time for me to return to the report of the "Science Breakthrough Award" academic conference in June.

Qin Ke clenched his fist slightly.

He is determined to win the Science Breakthrough Prize!
