God of black technology

Wang Yun was slightly taken aback, seeing Professor Li's frown deepening, he nodded slightly, and said with a little embarrassment, "Then...Professor Li, I'll give it a try." He doesn't know much about stream functions. Familiar, but the Laplace equation is still good.

The Laplace equation can be applied to fluid mechanics, that is, the flow field.This itself is a harmonic equation. Wang Yun took the pen handed over by graduate student Xiao Liu and began to write the numbers on the draft paper.

Graduate student Xiao Liu murmured in his heart, he did not believe that a high school student could really calculate such a complicated flow function.While watching Wang Yun write the exact same steps on the draft paper as he did before, he rubbed the bridge of his nose and thought, this guy is probably not a repeater, he has already done this calculation just now, it is impossible to figure it out .Now even if it is calculated again, can it still be calculated?

Xiao Liu pouted, thinking in his heart, a high school student is still a high school student after all.Not to mention beating graduate students, compared with college students, they are far behind.If you're just a college student, seeing him do the calculations, it doesn't make sense, and it's impossible to follow his steps to calculate step by step.Look at the high school student in front of him, saying that he is No. 1 in the Yucheng Mathematics Contest, it's nothing more than that.

His expression was normal, and by the way he looked at Wang Yun with some scrutiny.

However, what Xiao Liu never expected was—why did Wang Yun's writing steps differ from his own?

So what's the matter, what is he going to do?Xiao Liu froze for a moment, then continued to read.

Fog Grass—Xiao Liu's eyes widened, can't it be like this?This is the Laplace equation, how can this be?Why didn't he think of the plane potential flow of incompressible fluid, the flow function satisfies Laplace's equation.I feel that my fluid mechanics and flow field have been learned from dogs.

This guy uses the Laplace equation to calculate, Misty Grass——are high school students so stupid now?Is it possible to hang graduate students in high schools now?Wait... is this really a high school student?

Hi, so angry!He was hanged and beaten by a high school student. There is nothing more shocking than this.

"Professor Li, I figured it out." Wang Yun looked at Professor Li and said, "The final calculated result is 3. I checked it once, and the result is accurate."

Professor Li nodded, and asked in a deep voice, "What did you use to calculate it?"

"The Laplace equation."

"You're doing pretty well with calculus."

Wang Yun smiled embarrassedly, and the other researchers turned their heads in amazement to look at the high school student brought in by Professor Li. Is this really just a high school student?Calculus and fluid mechanics have been learned so slippery?Are the current high school students going to heaven?

"Okay, let's continue the experiment." Xiao Liu took a breath, and Wang Yun used the time he had calculated the flow function once and hadn't calculated it yet. After calculating it once, he checked it again.

Comparing people to people makes people mad.I, Fat Tiger, wanted to hit someone very much today. There was only such a small episode in the whole laboratory, and the others were still doing their own experiments in an orderly manner.The afternoon in spring darkened a little quickly. While they were still busy in the office, the sky outside had gradually darkened.When Professor Li was busy with the last experiment, he raised his hand and looked at his watch. It was almost eight o'clock in the evening.

"Let's end here for today's experiment." This is the first day of school, and this group of students cannot be allowed to stay in the laboratory all the time, and this is not a big experiment in itself, so it is completely unnecessary to stay in the laboratory.The graduate students and doctoral students dispersed, leaving only a few graduate students cleaning up the laboratory. Professor Li looked at Wang Yun in a daze and said, "Why haven't you left yet?"

"Professor." Wang Yun pursed his lips and thought for a while, "About fluid mechanics, I have a few questions I would like to ask you."

Professor Li nodded, "Your fluid mechanics is good, and your understanding of flow fields is not bad. And you are also good at mathematics."

The graduate student who was packing up next to him was stunned, Wucao, Professor Li praised him?He has been with Professor Li for more than a year, and he has never seen Professor Li praise others, but he did not expect——to praise others.

"What are your plans in the future?" Professor Li looked at Wang Yun and said, "If you want to develop in aerospace and aim at aerodynamics, I would actually suggest you go to Northwestern Polytechnical University. Like Yucheng, both It is a member of the E9 League of universities. Their ace major is aerodynamics."

Wang Yun hesitated for a moment, it was the first time he had heard of Northwestern Polytechnical University.Although he wants to learn aerodynamics now, he is not ready to spend all his energy on aerodynamics.After pondering for a while, Wang Yun said, "Professor Li, I am interested in aerodynamics, but I may also be interested in other physics."

"Oh?" Professor Li raised his brows, "Is there any physics you are interested in?"

"Particle physics, high-energy physics, etc." Wang Yun smiled sheepishly and said, "I'm very interested."

Professor Li nodded with a smile, "You are still young, it is time to be curious about everything. Peking University's School of Physics is also quite good, okay, you can ask me directly if you have any questions. If you have any questions, you can come to me directly in the museum."

"If I didn't go to other places, or it was a confidential experiment, you should be able to find me in the office of the Academy of Sciences and in this laboratory today."

"Thank you, Professor Li." Wang Yun sincerely thanked Professor Li, and in the eyes of several graduate students, he gradually drifted away from Professor Li.

One of the graduate students rubbed his eyes vigorously, and said in disbelief, "I'll go, is that really our Professor Li?"

"Otherwise, who do you think he would be?"

"No, what I mean is, our professor is too scary, right?"

"What's so scary?"

"I'm going, isn't it scary?"

"???"

The graduate students next to him didn't understand what was so scary about the professor.

"He never praised anyone, but he actually praised a high school student. Is there something wrong with my ears?"

"Hehe, is that a normal high school student? Can a normal high school student do the Laplace equation? Can he understand the flow field so well?"

"..." What you said was so reasonable that I couldn't even refute it.Touching his head, the graduate student thought, what the hell is this happening.

…………

Walking with Professor Li, Wang Yun felt a little stressed.Professor Li pondered and said, "How do you learn about turbulence? I think you have a good understanding of flow functions, and potential functions should be good too. Coupled with your foundation in mathematics, no matter what physics you do in the future, you will be good. Your future thoughts Is it studying physics?"

"Yes." Wang Yun nodded, "I think... to study controllable nuclear fusion."

"Controlled nuclear fusion." Professor Li pursed his lips, walked in silence for a while, and then continued, "Controlled nuclear fusion is not so easy to study, I am not very familiar with the nuclear industry. But I know that after many years of research, there is almost no progress. Now that I have the ability to develop it, I can only look at ITER."

"The progress of the United States is not slow. In addition to ITER, they should also be researching themselves."

"Should... have some research." Professor Li said confusedly, "I'm not very clear about the things over there, you are still early. Your math foundation is not bad, and if you participate in the national competition, you have a great chance of winning the championship. Have you figured out what school to go to?"

"Professor Li, you said that if I win the championship, can I enter the Yuanpei Academy of Peking University?"

Professor Li glanced at Wang Yun, then nodded and said, "You are qualified to enter Yuanpei Academy now." When he said this, Professor Li smiled slightly.According to the general situation, Wang Yun got the ranking in the mathematics competition. Even if he wants to enter Beijing University, he can only be in the School of Mathematics.But the champion is different. I believe that the Yuanpei Academy will welcome him if he wins the national championship and goes to Beijing University.

After all, since he can win the championship, he will naturally represent China in the IMO.After arriving abroad, countless invitation letters from famous schools came one after another, and Peking University... probably just a little raindrop.

After walking to the cafeteria, Wang Yun asked Professor Li several questions about the flow field and fluid mechanics, and returned to the dormitory contentedly.Yuan Chengde has not returned to the dormitory, and neither have the rest of the students.But the entire dormitory building has already started to become lively, probably because of the start of school.Those students watched Wang Yun walk into the dormitory and looked around, then said to the people next to him, "Who is this, isn't there no one living next to us?"

"The training team will leave in a few days." The student next to him shrugged his shoulders. This is no secret in the entire dormitory building.It was the same last year. After returning to the dormitory, Wang Yun reopened Fluid Mechanics and read it.After Professor Li's explanation, Wang Yun felt that his views on fluid mechanics had deepened a lot.It seems that it is better to talk to the professor.Just working behind closed doors will probably always be behind closed doors.

In the next few days, Wang Yun went to the office of the Institute of Physics to look for Professor Li almost every day.

Professor Li also answered Wang Yun's questions very patiently, and both parties were very satisfied.Professor Li thinks that Wang Yun is a talented person, and Wang Yun thinks that Professor Li has a very deep understanding of fluid mechanics.

The last day of the training team finally came.Wang Yun did not go to the Institute of Physics where Professor Li was, but was arrested by Professor Wan and brought back for an exam.Sitting in the seat, Professor Wan raised his eyebrows and said, "This month, everyone must have worked very hard. Tomorrow is April, and you will win the 15-year national competition in more than a week."

"We are fully prepared for the national competition this time. I believe everyone is more or less confident about the national competition, right?" Professor Wan looked at all the students in the classroom.Students like Yuan Chengde, Wang Qiuyang, and Leng Xiao are pretty good. What's more surprising is that Rong Lei's entry is also very high, and it is very likely that he will get a good result in this competition.

As for Wang Yun, Professor Wan is sure that this guy will never forget the formula and steps.It must be very appropriate to be able to obtain the national one.

"Then, about the results of the one-month training camp." Professor Wan said with a smile, "I'm going to test you all. Next, please put away your textbooks. In two hours, everyone has the same papers. This time The difficulty of the exam is about the same as the final paper of the last national competition. I just want to see how far you can do it. By the way, don’t be nervous during the national competition. But take advantage of the opportunity. It turns out that everyone is the elite of each province and city, and the difference will not be too big. But if the mentality is not good-then the score will be greatly increased."

When Professor Wan said this, the students silently glanced at Wang Yun, and complained in their hearts that it was not much different.Obviously the difference is huge, okay?Look at Wang Yun, who has been running to the Institute of Physics every day for the past few days, and I heard that he is almost familiar with the Institute of Physics of Yucheng University.As for them, except for Professor Wan and Professor Wan's doctoral students, they don't know anyone in the School of Mathematical Sciences.

Sometimes the gap between people is even bigger than the gap between humans and dogs. Thinking about it, I feel so embarrassed!

Everyone is also a high school student, why are you so good, can you give me a way to survive?These gods of learning have been hit hard recently, and from time to time they heard a few high-end and elegant words from Wang Yun's mouth.

For example, what are the flow fields, what are the incompressible fluids, etc., there are so many, they even suspect that they have never read the book at all.

What kind of feeling is it to study with an evildoer?All the students felt that they had something to say, but no matter how they thought about it, Professor Wan's test paper had already been sent out. After the students got the test paper, the first time they got it was to review the questions.Reviewing questions is a very important thing. If the reviewing questions are wrong, then the next answers will be all wrong.

This paper is the subject of Professor Wan's investigation of the results of the entire training team this month, and the difficulty is similar to last year's national rematch.There are only two preliminary rounds and semi-finals in the national competition, and No.1, No.2, etc. will be selected after the semi-finals.

For Wang Yun and Yuan Chengde, this paper is not difficult, it can even be said to be a bit simple.They had been doing very difficult papers a few days ago, but when they got this paper, they were stunned.

This is... a little too simple, right?Is this the level of the national competition?

"Don't underestimate the difficulty of the national competition. This difficulty is basically higher than that of the IMO. If you can get the top position in the national competition, basically in the IMO competition, if you don't make mistakes, you can win the IMO championship. It's still very stable." Professor Wan said while the students were doing papers.

After Wang Yun wrote the last question first, he worked on the questions from bottom to top.The previous questions are very simple, and the more difficult they are, the more they will be at the end.But Wang Yun, who finished the last question, felt that these questions were really a bit too simple, with this level of difficulty... emmmmm national competition seems to be nothing more than that.

Probably because I have studied too much during this time, so I feel that the papers with the same difficulty as the national competition are almost the same.

Professor Wan walked up to Wang Yun, holding a thermos in his hand, and looked at it for a while.Then he said loudly, "By the way, just to remind you, you can have a good sleep after you go home tonight. Tomorrow is the weekend, and you can choose whether to go to class according to the situation of your own school. Next Thursday morning, you will still be in school." Gather at Yucheng University. There will be a teacher leading the team to take you to the capital to participate in the math competition. The math competition is on the weekend, that is, Saturday morning. Don’t be nervous when you arrive, first check to see if you have missed anything, and finally do the questions You have to be serious when you do it.”

As soon as he finished speaking, Wang Yun raised his hand and said, "Professor, I'm done."

"En." Professor Wan nodded, stretched out his hand and said, "Give me the paper." After taking the paper, Professor Wan looked at it for a while, and it was very good, with almost no mistakes or omissions.Nodding his head, he looked at everyone again and asked, "Is there anyone else who wants to hand in the paper?"

At this time Yuan Chengde raised his hand and said, "Professor, I want to hand in the paper."

After Professor Wan collected Yuan Chengde's papers, he found that the rest of the people did the fastest, and there were still several questions that could not be completed.

It seems that Guoyi still has to look at Wang Yun and Yuan Chengde this time. Thinking so, he waved his hand and said, "You go back and clean up and go home." It was originally afternoon, after they finished cleaning, there was still A long time to rush home.For this group of high school students, Professor Wan is still very relieved.

After all, after being with this group of high school students for a month, Professor Wan still has a good idea of ​​what kind of temperament they are.Let them go home by themselves, trusting that they will be able to return to their own homes in no time.

"I'm going, aren't they too fast?" No one knew who whispered such a sentence, Wang Yun and Yuan Chengde went back to the dormitory to pack their salutes.After a while, they walked to the gate of Yucheng University and waited for the bus.

Although the two families are not in the same place, they are both facing the same direction.

Yuan Chengde looked at Wang Yun with a smile and said, "The national competition is coming soon, Yunshen, do you have any ideas?"

"Thoughts?" Wang Yun pondered for a while and said, "It's pretty good, the national competition is about to start, and I want to see what the elites from other provinces and cities are like."

Yuan Chengde smiled, "It is estimated that there are not many people who can fight like you."

"Maybe, it's normal for Huaxia to have a population more than one billion, and there are a few geniuses." Wang Yun shrugged his shoulders, following his thoughts.Guoyi is definitely a sure thing. If you don't win the national championship, you will probably only be able to enter the Mathematical Academy of Beijing University.But the major he wants to study is physics, so he might as well stay in Yucheng University to study physics.

However, the physics major of Yucheng University is really poor, and it is almost incomparable with the physics department of other key universities.

"Let's talk about it when the time comes." Wang Yun said after a long silence, "It's not certain whether I can get the National First Capital."

Yuan Chengde shook his head with a smile and did not continue speaking.

But I thought in my heart that for Wang Yun, it should be relatively easy to get the first degree.After all, Wang Yun's mathematics has really surpassed his peers by a lot.

"Tell me, will we meet an opponent like you?" Yuan Chengde was very curious. If in the national competition, it would be very exciting to meet such a terrifying opponent from other provinces and cities as Wang Yun. Desperate?
