Chapter 108 Linear Transformations
Well, this brat!Ma Bo rubbed the space between his brows, if he had known, he would not have dragged his senior brother away and asked him to interrogate you eight hundred times.But you still laugh, Wang Yun is about to burst into tears.
After a long time, Wang Yun touched the tears on his body tremblingly, and his face was almost contorted with laughter.Marbo turned his head to look at other places, and after a while, he muttered, "What's so funny, is it abnormal for a scientific research dog to want a wife?"
"No, no...it's not abnormal." Wang Yun let it go, "I was just thinking, Brother Ma, when you hugged your senior brother's paralyzed face and called you wife, the expression on your senior brother's face must be wonderful."
Rubbing his brows, he was waiting for him here.
"My brother didn't go that time, so I drank too much that time." Ma Bo sighed and said, "The people in their army drink too much, they can't be provoked."
"But it's still fun." Wang Yun looked at Ma Bo and said, "The first time I saw Ma Ge, I thought Ma Ge was a high-ranking person, after all, he is quite handsome. He is a doctoral student again. This kind of coldness and abstinence is quite popular with girls."
"???" There is such a saying?Ma Bo looked at Wang Yun in shock, "What you said is true?"
"Based on my personal experience, it should be good. As for whether it is true or not, I still need to practice it." Wang Yun just finished speaking, and saw Ma Ge with a serious face, "Do you think I am more cold-hearted like this?" ?”
"What about you..." Wang Yun was silent for a while, "It's called showing face, not being cold. Believe it or not, you will only get two slaps when you strike up a conversation with a girl like this."
"Mist Grass." Marbo rubbed his head and said, "Girls are really incomprehensible creatures, even more incomprehensible than my physics."
When he said this, Ma Bo continued to sigh, "I think that I can only live with physics in this life. Tonight is probably my wedding night with physics?"
"Hahahaha..." Brother Ma, are you a joke sent by a monkey?Wang Yun almost couldn't stop laughing. He thought that the people in UCAS were so cold and cold, but he didn't expect such a funny thing to exist.
He rubbed the center of his brows, "Why do I think Brother Ma, you are quite good at talking." Before he knew it, Wang Yun's embarrassment dissipated a lot.
"Accept your good words." Ma Bo said, "If possible, I think I should find a wife this year."
"Ma Bo, I wish you good luck!" Wang Yun patted Ma Bo on the shoulder and did not continue.
After the two chatted for a while at the dinner, Wang Yun was dragged away by Brother He.Looking at the countless curious eyes around him, Brother He laughed and said, "Do you know who he is?"
"Who is this?"
"Wucao, Lao He, where did you get such a big son?"
"No, where does Lao He have such a big son, he can't be Lao He's younger brother, right?"
"Mist Grass, the little guy looks quite unique."
"Hey, this juicy little face, let my sister touch it—"
"???" Wang Yun took a few steps back, Brother He asked him to come over and get to know the scientific researchers here, and saw a group of strange brothers and sisters, Wang Yun was a little scared. "Brother He, let me tell you, what the hell kind of formation is this?" Wang Yun felt a little uncomfortable, at this moment Brother He said with a smile, "Put your hands away, Xiao Wang is a flower in our experimental group. "
"???" What kind of devil metaphor is this?Wang Yun was in a bad mood, and Brother He continued, "Xiao Wang is now the youngest person in each experimental group of our research project?"
"It looks very small."
"Little Fresh Meat!"
"Envy, full of collagen."
"Take it away, take it away." Brother He slapped him several times in a row, wanting to take advantage of the chaos to touch Wang Yun's face, and said, "This is the foreign aid we Yucheng University invited from the Peking University Mathematics Research Institute. If you If it breaks, we, Yucheng University, cannot afford to pay for it.”
"..." No, Brother He, can we talk properly?No matter how I sound, I don't sound like a person, but like an object.
Is it my illusion?Wang Yun looked at Brother He, who was already a little drunk at this time.His face was a little red, and he was happily introducing Wang Yun to everyone. After a while, everyone began to talk about it——
"I'll go, Beijing University Mathematics Research Institute? Can't you, so young?"
"Is the Institute of Mathematics of Beijing University so young now?"
"I'm going, this person is from the Mathematics Research Center of Beijing University? Could it be—I'm going, if I'm not mistaken, you are the champion of this year's IMO competition."
"You wrote the 'Proof of the New Mason's Conjecture' on Mathematics Applications?"
"Boss, boss!"
"Please teach us some mathematics, sir, I'm about to be driven to collapse by the Reynolds number."
"The continuity equation is also very broken, okay?"
"Every time I see a big guy from the mathematics academy, I feel envious. These days, I can't learn mathematics well, and I can't understand physics at all."
"..."
Everyone was chatting, and Wang Yun was listening, smirking from time to time.Like a boy with a smirk, it took a while before he dispersed.
Brother He said, "Look, everyone is quite enthusiastic."
"I'm afraid I can't bear this kind of enthusiasm!" Wang Yun covered his face and said dumbfoundedly, "It's too enthusiastic, I feel a little unbearable." Then, he said to Brother He, "Brother He , I'll go out first to catch my breath."
"Go, go." Brother He said, waving his hands, "Don't go too far, after the dinner party is over, go back to the dormitory early. There is still work tomorrow morning, that turbulent flow is really not a thing .”
Emmmmm......
Wang Yun thought about it, and it seems that the turbulent pulsation is not a thing in the first place.There seems to be nothing wrong with what Brother He said, um, forget it, let's go out first to take a breath.
Walking out of the hotel, Wang Yun watched the lights shining outside.Outside the gate of Xigong University, it is quite prosperous.Stretching, Wang Yun walked down the steps slowly.Standing in front of the hotel grounds, looking into the distance.At this time, the sky was already dark, a few scattered stars hung in the sky, and a cool wind suddenly blew over.
Passing by his side, Wang Yun took a deep breath and said with emotion in his heart, this is the smoke and fire.
With the sound of the horn of the car not far away, Wang Yun slowly walked to the front of the stands, leaned on the railing and looked down.
There was a sudden roar in the sky, and a plane flew over Wang Yun's head.
Um?Airplanes - hmmm!Wang Yun's eyes widened, airplanes, wait, airplanes... turbulent, laminar flow.Large eddy simulation requires a high Reynolds number, and the viscosity of Reynolds number must also be considered, as well as functions.
I seem to... thought of something.Wang Yun turned around and walked to the front of the hotel.At this time, the music in the hotel was still going on, Wang Yun was thinking while walking, and after a while, he saw Ma Bo not far away.Walking to his side, Marbo was still talking and laughing when he approached.
This group of people who were straightening their heads looked at Wang Yun.
"Brother Ma, I suddenly have an idea." Wang Yun looked at Ma Bo eagerly, and the slightly drunk Ma Bo was stunned for a moment, "What do you think?"
"It just occurred to me just now, have we forgotten the stickiness?" Wang Yun shook his head when he said this, "No, it's not that we forgot the stickiness of the Reynolds number."
"Ha." Ma Bo may be a little unconscious now, and looked at Wang Yun in a daze.The others didn't hear what Wang Yun said amidst the loud music.As soon as Wang Yun was in a hurry, he took Ma Bo's hand and ran to the gate of the hotel.Ma Bo, who was originally tall and burly, couldn't move him.
Although Ma Bo didn't know what Wang Yun was anxious about, he ran to the hotel gate with him.Thinking in my heart, maybe Xiao Wang has something important to tell him.
But unexpectedly, Wang Yun was still running in front of the hotel gate.
At this time, Wang Yun could no longer move Ma Bo.He looked back at Marbo, and Marbo said in a daze, "Where are we going?"
"Laboratory." Wang Yun pulled Ma Bo directly and continued towards Xigong University. Ma Bo was shocked and fully awake.Looking at Wang Yun, he said in a daze, "Now, what are you going to do in the laboratory?"
"I had some new ideas just now. Although I don't know if it's right or not, I can give it a try." After speaking, Wang Yun let go of Ma Bo's hand, looked at him and asked, "Will you go?"
"Go." Marbo nodded. Although he was having a good chat, he was a little upset to be pulled out out of nowhere.But for work, Wang Yun really has nothing to blame.
Ma Bo followed Wang Yun's footsteps, and asked as he walked, "Do you have any ideas about going to the laboratory in such a hurry?"
"When we calculate the Reynolds number, the viscous calculation is included, right?"
"That's right." Ma Bo responded, "The viscosity should not be wrong. I have checked your continuity equation several times, and there are no mistakes. However, the final result is wrong." When he said this, Ma Bo He also became serious, "Why did you think of the problem of stickiness? According to my observation, the most error-prone thing is stickiness."
"Is there something wrong with the flow field?" Wang Yun said as he walked, "I don't have time to tell you in detail, anyway, I think it must be a problem with the sticky item."
"..." Marborn said with a sigh, "You are good at mathematics, maybe you really discovered something."
Walking into the campus of Western Polytechnic University, the two quickly took out their ID badges, put them on, and walked directly to the laboratory building.At this time, the guard saw the two people coming from outside, and even though they were wearing ID cards, they still asked, "What are you doing in the lab so late?"
Wang Yun looked at Ma Bo, obviously Ma Bo was already very familiar with the guards guarding here.
"We are in a hurry and want to go back to the laboratory to do it."
The guard nodded and let the two of them in without saying anything.For one thing, even though Ma Bo was not their leader, when the guards saw Ma Bo, they still had to call the chief.Secondly, Ma Bo and the others are already familiar with it, so they are very relieved to let them in.
After the two walked in, the two guards whispered, "You said these scientific researchers are really interesting. I heard that they are having a dinner party at night. Instead of playing at the dinner party, they ran to the laboratory do things."
Another guard smiled, and then said, "Probably this is the biggest difference between us and their researchers."
"Never mind." The guard smiled, but didn't speak.Anyway, he didn't think about becoming a scientific researcher or anything like that.
Taking out the key, Marbo opened the door.Then the lights were turned on, and the moment the incandescent lamp was turned on, Wang Yun squinted his eyes.Ma Bo casually found a place to sit down, looked at Wang Yun and said, "If you have any thoughts, just write them on the blackboard."
Wang Yun nodded slightly, picked up the blackboard eraser, and erased all the formulas on the blackboard just now.
Ma Bo didn't speak, but just looked at Wang Yun quietly.Picking up the chalk, Wang Yun first wrote down the first line of formula on the blackboard.Ma Bo frowned slightly. This line of formula was exactly the same as the formula he had calculated just now, that is to say——this problem was not what Wang Yun thought of just now.
Subsequently, Wang Yun wrote down the second formula.
Continuity equation, Marbo did not speak.He is already very familiar with the Reynolds number and the continuity equation, almost at the memorization level.
I just didn't expect that Wang Yun was already using the continuity equation at this step.Their calculations are nothing more than Reynolds numbers.
Wang Yun was writing and thinking at the same time. After a while, Ma Bo squinted his eyes and began to read.
He didn't write out a few steps in total, but this step is very different from the previous one.Marbo watched intently, and he always felt that after reaching this step, all the formulas they had completed before had been overturned.
The sound of "swipe, swipe, swipe" still rang on the blackboard, and the chalk in Wang Yun's hand touched the blackboard, making a rustling sound.The more Marbo watched, the more fascinated he became.Then slowly opened his eyes, the pupils dilated slightly.He stood up suddenly and said, "Why did I forget this method." As he spoke, he turned around and walked outside.
Wang Yun didn't care about Ma Bo who had gone away, but was still calculating on the blackboard.
Ma Bo rushed out of the laboratory excitedly, and ran to the front of the laboratory building.
Seeing Ma Bo coming out, the guard froze for a moment before saying, "Brother Ma, weren't you still inside just now? It's over after a while?"
Shaking his head, Ma Bo said with a smile, "No, no, no, it's because a new problem has been discovered. No, it's not a new problem, but a problem has been solved." When he said this, Ma Bo laughed sincerely, "In short, this time it can be regarded as a major discovery."
"..." Before the guard could speak, he saw that Ma Bo was running towards the gate of Xigong University excitedly.
"???" The guards looked at each other, thinking in their hearts, maybe this brother Ma has gone crazy because of his research?Thinking about it, it's really scary. Fortunately, they are not doing scientific research.Unexpectedly, scientific research can really drive people crazy.
Even though Marbo has been out of the laboratory for a long time, he is still in a state of excitement.
Walk out of the gate of Xigong University and walk directly to the hotel.
At this time in the hotel, there was a lot of wine and wine, and Ma Bo looked at the faces attentively.After a while, I saw my tutor talking with Professor Li.
He walked up to the mentor, and the mentor looked at Ma Bo who came over and smiled and said, "Come on, Lao Li, look, this is my ineffective disciple." Having said this, Ma Bo's mentor pointed He said with a smile, "Now I am studying for a doctoral student here, Xiao Ma, quickly call Professor Li."
"Hello, Professor Li." Ma Bo called Professor Li respectfully, but unexpectedly, Professor Li just snorted coldly and muttered, "What's so great about Zhibo."
"I thought you were hiding some treasure." Professor Li's words made Ma Bo's tutor laugh.Ma Bo's mentor is an academician of the Huaguo Academy of Sciences and a professor of the National University of Science and Technology.He has made a lot of achievements in CFD. Professor Li is about the same age as him, and everyone is old acquaintance. When you are old, your reputation and scientific research achievements are just floating clouds.The only one who can compare now is his own disciple.
Professor Zhao is still very satisfied with Ma Bo, and he is also his right-hand man.In front of old friends, I couldn't help but want to show off.
A 24-year-old doctoral student is not so common.Especially in his hands, even more so.
Seeing Professor Li's face flushed slightly, Professor Zhao immediately said, "Old Li, don't worry, you will still meet good disciples in the future."
"Hehe." Professor Li sneered, "I'll take you to see some other day, what is a good seedling, even you, a crooked melon, dare to call it a good seedling?"
Professor Zhao felt a little bored, looked at Ma Bo and said, "Little Ma, what do you want from me?"
"Professor." Ma Bo pondered for a while, "Our experimental team seems to have calculated something interesting, and I would like to invite you to take a look."
"Your experimental group?" Professor Li raised his head and looked at the hotel, and found that several of his incompetent disciples were still chatting with each other. At this time, he found that one of them was not there.
"No." Professor Zhao raised his eyebrows and said, "Professor Li's disciples are all here."
"There is one more person." Professor Li said in a deep voice, "Let's go, Lao Zhao, I'll show you today what makes a good seedling." One by one, what are you still eating here, hurry up. Something big happened to your experimental group!"
"Ah." Brother He said in a daze, "Boss, what big things can happen in our experimental group?" He scratched his head, thinking in his heart, what big things can happen in a marginal experimental group is rare.
But seeing that his boss had already walked towards the gate of the hotel, Brother He had no choice but to call a few brothers to follow the boss.
After walking out of the hotel, Professor Zhao asked, "Little Ma, what is it?"
Ma Bo said with a smile, "I can't say anything about this matter. It's better for you, the instructor, to go and see for yourself. It seems that some errors in the large eddy simulation have been found out."
"What method?" Professor Zhao took a deep look at Ma Bo, and he couldn't think of a solution after several days of continuous research.I was found out today, aren't you kidding me?
"It seems to be a linear transformation?" Ma Bo was stunned for a moment, and said to his tutor Professor Zhao with a wry smile, "Teacher, you know that I'm really not very good at mathematics."
Professor Zhao nodded, but did not speak.Is it possible to work out their errors with a linear transformation?He looked at Marbo and said, "Are you sure?"
"Yeah." Marbo nodded.
Brother He was still confused behind Professor Li. He didn't know anything, so he was called over.The brothers behind them were also confused, until they came to the front of the laboratory building, they put on their ID cards and walked into the laboratory building.
When he came to the laboratory of the experimental group, the first thing that caught Professor Zhao's eyes was a student who looked very immature.This student looks quite good, but a little short.Standing on the podium, different formulas are written.
At this time, Professor Zhao was deeply attracted by the calculation formulas on the blackboard. As the student on the podium wrote faster and faster, Professor Zhao's eyes became more and more active.
He muttered to himself, "That's right, that's right, I actually found the wrong value."
Ma Bo was also taken aback for a moment. He didn't expect that Wang Yun had written so many calculations just after he went out for a while.When Wang Yun stopped writing, he smiled at Ma Bo, and then saw so many pairs of eyes looking at him.Wei Wei was stunned for a moment, and said, "Uh, I can only calculate up to this point. All the wrong values must not be calculated now. But it is better to use linear transformation to find the wrong values, but the amount of calculation is relatively large."
Professor Zhao nodded, looked at Professor Li and said, "Where did you find this person?"
"People from Peking University's Mathematics Research Institute, you have made up your mind." Professor Li smiled and said, "If you dare to pay attention, believe it or not, Lao Yang will directly overturn your laboratory at the National University of Science and Technology."
"He dares!" Professor Zhao raised his eyebrows, then looked at Wang Yun, and the more he liked it, the more he liked it, and said happily, "Little classmate, are you from the Beijing University of Mathematics?"
"Yuanpei Academy." Wang Yun smiled shyly, "I haven't gone to Beijing University to study yet, and I will be a freshman in the second half of the year."
"..." Terrible, terrible.Today's students are already so evil, I think they didn't understand these things at all when they went to college.
"Are you planning to take the postgraduate entrance examination? Should the National University of Science and Technology consider it?" Professor Zhao looked at Wang Yun with a smile.
Wang Yun looked at Professor Li as if asking for help. At this time, Professor Li stood up and said, "Tell me what you think, how to use linear transformation to find the wrong value?"
"Because I thought of a problem today, the error in the value is still an error in the function after all, so I thought about trying to use mathematics to find the wrong value." When he said this, Wang Yun smiled embarrassedly, "I only found two, I'm sorry, and I'm bothering Brother Ma."
"No trouble, no trouble." It's too late for him to be happy now, although he knows that there is still a long way to go before completely finding out the wrong value.But two wrong values have been found, can the others be far behind?Certainly not!
Professor Zhao also nodded and said, "Your functional analysis is very good, and you also have a lot of research on fluid mechanics. I think you can learn about CFD. In this regard, the University of Science and Technology of my country is the first, who dares to say the second!"
Emmmmm......
What is the turbulence laboratory of Beijing University?The current professors are already so stupid in order to grab students?
"Put it down, don't go to the turbulence laboratory of Peking University to ask for data if you have the ability." Professor Li did not hesitate to expose his old friend, and he would only say that when he was so familiar with him.
"Okay, you are tired today, go back and rest early." Professor Li waved his hand, "Continue to search according to this idea tomorrow, and we must finish everything within two months."
"Hey." Professor Li's students responded and all dispersed back to their dormitories.
Wang Yun stepped off the podium and said to Professor Li and Zhao, "Professors, then I will go back to rest first."
"Go back quickly." After speaking, Wang Yun said goodbye to the two professors and left the laboratory.
Looking at Wang Yun's back as he drifted away, Professor Zhao said, "Old Li, you can't do this."
"Huh?" Professor Li sneered, "What kind of argument is that?"
"How can such a good seedling be placed in the marginal experimental group? In any case, it must be in the core experimental group—" Professor Zhao was very satisfied with Wang Yun, so he wanted to transfer Wang Yun to the core experimental group.
However, Wang Yun was brought by Professor Li. Without Professor Li's approval, it is really impossible for him to directly transfer people to the core experimental group.
Isn't this a slap in the face on the spot? !Professor Zhao definitely couldn't do this kind of thing.
"You have a good idea." Professor Li said as he walked, "That's what I planned too, but it doesn't work."
Professor Li sighed, "I didn't borrow people, but Lao Wan borrowed them. Before leaving, Lao Wanqian reminded Wan Wan not to touch core topics, or even handle core data."
"Why?" Professor Zhao and Professor Wan also knew each other, so he didn't quite understand.Given Professor Wan's personality, he definitely wouldn't say that.But this time, such a good seedling slipped away from under their noses, which doesn't make sense at all.
"Old Wan said, let's not delay his bright future." When he said this, Professor Li smiled wryly, "Princeton invited him to study at Princeton again and again, no matter what he said, he became famous at a young age. There are also great ones. In the future, why bother to conduct scientific research incognito like our group of bad old men."
"What can Princeton offer him, but our National University of Science and Technology can't give it?" Professor Zhao was a little unbelieving, "Why do you have to study abroad and drink foreign ink to be considered a talent?"
"Princeton can send him to the Fields Awards stage, but can you, UCAS?" Professor Li squinted at Professor Zhao.
"..." Professor Zhao snorted, "What's so great about the Fields Medal."
"But it is undeniable that if he returns to China with the halo of the Fields Medal, he will be different from the PhDs who stay in China." Professor Li said dumbfounded, "Otherwise, why do so many students go abroad to be gilded?"
The topic was a bit heavy, and the two professors glanced at each other, but neither spoke.
Indeed, the students who stayed in China must not have received as much attention as the students who returned from studying abroad before they produced results.Especially - Ph.D. students from world-class prestigious universities.
"It's not that I don't let him enter the core group, but after I let him enter the core group. Lao Wan is going to fight me hard." Professor Li sighed, "That's why I arranged him in the experimental group for data calculation. "
"I didn't expect it to be gold, and it will shine everywhere." Professor Li raised his brows and looked at the professor, "How about it, let me tell you, let me show you a real good seedling. How about this good seedling?"
"Okay, okay, okay!" Saying yes three times in a row, it seems that Professor Zhao is already very satisfied with Wang Yun.
After a long time, Wang Yun touched the tears on his body tremblingly, and his face was almost contorted with laughter.Marbo turned his head to look at other places, and after a while, he muttered, "What's so funny, is it abnormal for a scientific research dog to want a wife?"
"No, no...it's not abnormal." Wang Yun let it go, "I was just thinking, Brother Ma, when you hugged your senior brother's paralyzed face and called you wife, the expression on your senior brother's face must be wonderful."

"What about you..." Wang Yun was silent for a while, "It's called showing face, not being cold. Believe it or not, you will only get two slaps when you strike up a conversation with a girl like this."
"Mist Grass." Marbo rubbed his head and said, "Girls are really incomprehensible creatures, even more incomprehensible than my physics."
When he said this, Ma Bo continued to sigh, "I think that I can only live with physics in this life. Tonight is probably my wedding night with physics?"
"Hahahaha..." Brother Ma, are you a joke sent by a monkey?Wang Yun almost couldn't stop laughing. He thought that the people in UCAS were so cold and cold, but he didn't expect such a funny thing to exist.

"It looks very small."
"Little Fresh Meat!"
"Envy, full of collagen."

Brother He slapped him several times in a row, wanting to take advantage of the chaos to touch Wang Yun's face, and said, "This is the foreign aid we Yucheng University invited from the Peking University Mathematics Research Institute.

"Go." Marbo nodded. Although he was having a good chat, he was a little upset to be pulled out out of nowhere.But for work, Wang Yun really has nothing to blame.
Ma Bo followed Wang Yun's footsteps, and asked as he walked, "Do you have any ideas about going to the laboratory in such a hurry?"
"When we calculate the Reynolds number, the viscous calculation is included, right?"
"That's right." Ma Bo responded, "The viscosity should not be wrong. I have checked your continuity equation several times, and there are no mistakes. However, the final result is wrong." When he said this, Ma Bo He also became serious, "Why did you think of the problem of stickiness? According to my observation, the most error-prone thing is stickiness."
"Is there something wrong with the flow field?" Wang Yun said as he walked, "I don't have time to tell you in detail, anyway, I think it must be a problem with the sticky item."
"..." Marborn said with a sigh, "You are good at mathematics, maybe you really discovered something."
Walking into the campus of Western Polytechnic University, the two quickly took out their ID badges, put them on, and walked directly to the laboratory building.At this time, the guard saw the two people coming from outside, and even though they were wearing ID cards, they still asked, "What are you doing in the lab so late?"
Wang Yun looked at Ma Bo, obviously Ma Bo was already very familiar with the guards guarding here.
"We are in a hurry and want to go back to the laboratory to do it."
The guard nodded and let the two of them in without saying anything.For one thing, even though Ma Bo was not their leader, when the guards saw Ma Bo, they still had to call the chief.Secondly, Ma Bo and the others are already familiar with it, so they are very relieved to let them in.
After the two walked in, the two guards whispered, "You said these scientific researchers are really interesting. I heard that they are having a dinner party at night. Instead of playing at the dinner party, they ran to the laboratory do things."
Another guard smiled, and then said, "Probably this is the biggest difference between us and their researchers."
"Never mind." The guard smiled, but didn't speak.Anyway, he didn't think about becoming a scientific researcher or anything like that.
Taking out the key, Marbo opened the door.Then the lights were turned on, and the moment the incandescent lamp was turned on, Wang Yun squinted his eyes.Ma Bo casually found a place to sit down, looked at Wang Yun and said, "If you have any thoughts, just write them on the blackboard."
Wang Yun nodded slightly, picked up the blackboard eraser, and erased all the formulas on the blackboard just now.
Ma Bo didn't speak, but just looked at Wang Yun quietly.Picking up the chalk, Wang Yun first wrote down the first line of formula on the blackboard.Ma Bo frowned slightly. This line of formula was exactly the same as the formula he had calculated just now, that is to say——this problem was not what Wang Yun thought of just now.
Subsequently, Wang Yun wrote down the second formula.
Continuity equation, Marbo did not speak.He is already very familiar with the Reynolds number and the continuity equation, almost at the memorization level.
I just didn't expect that Wang Yun was already using the continuity equation at this step.Their calculations are nothing more than Reynolds numbers.
Wang Yun was writing and thinking at the same time. After a while, Ma Bo squinted his eyes and began to read.
He didn't write out a few steps in total, but this step is very different from the previous one.Marbo watched intently, and he always felt that after reaching this step, all the formulas they had completed before had been overturned.
The sound of "swipe, swipe, swipe" still rang on the blackboard, and the chalk in Wang Yun's hand touched the blackboard, making a rustling sound.The more Marbo watched, the more fascinated he became.Then slowly opened his eyes, the pupils dilated slightly.He stood up suddenly and said, "Why did I forget this method." As he spoke, he turned around and walked outside.
Wang Yun didn't care about Ma Bo who had gone away, but was still calculating on the blackboard.
Ma Bo rushed out of the laboratory excitedly, and ran to the front of the laboratory building.
Seeing Ma Bo coming out, the guard froze for a moment before saying, "Brother Ma, weren't you still inside just now? It's over after a while?"
Shaking his head, Ma Bo said with a smile, "No, no, no, it's because a new problem has been discovered. No, it's not a new problem, but a problem has been solved." When he said this, Ma Bo laughed sincerely, "In short, this time it can be regarded as a major discovery."
"..." Before the guard could speak, he saw that Ma Bo was running towards the gate of Xigong University excitedly.
"???" The guards looked at each other, thinking in their hearts, maybe this brother Ma has gone crazy because of his research?Thinking about it, it's really scary. Fortunately, they are not doing scientific research.Unexpectedly, scientific research can really drive people crazy.
Even though Marbo has been out of the laboratory for a long time, he is still in a state of excitement.
Walk out of the gate of Xigong University and walk directly to the hotel.
At this time in the hotel, there was a lot of wine and wine, and Ma Bo looked at the faces attentively.After a while, I saw my tutor talking with Professor Li.
He walked up to the mentor, and the mentor looked at Ma Bo who came over and smiled and said, "Come on, Lao Li, look, this is my ineffective disciple." Having said this, Ma Bo's mentor pointed He said with a smile, "Now I am studying for a doctoral student here, Xiao Ma, quickly call Professor Li."
"Hello, Professor Li." Ma Bo called Professor Li respectfully, but unexpectedly, Professor Li just snorted coldly and muttered, "What's so great about Zhibo."
"I thought you were hiding some treasure." Professor Li's words made Ma Bo's tutor laugh.Ma Bo's mentor is an academician of the Huaguo Academy of Sciences and a professor of the National University of Science and Technology.He has made a lot of achievements in CFD. Professor Li is about the same age as him, and everyone is old acquaintance. When you are old, your reputation and scientific research achievements are just floating clouds.The only one who can compare now is his own disciple.
Professor Zhao is still very satisfied with Ma Bo, and he is also his right-hand man.In front of old friends, I couldn't help but want to show off.
A 24-year-old doctoral student is not so common.Especially in his hands, even more so.
Seeing Professor Li's face flushed slightly, Professor Zhao immediately said, "Old Li, don't worry, you will still meet good disciples in the future."
"Hehe." Professor Li sneered, "I'll take you to see some other day, what is a good seedling, even you, a crooked melon, dare to call it a good seedling?"
Professor Zhao felt a little bored, looked at Ma Bo and said, "Little Ma, what do you want from me?"
"Professor." Ma Bo pondered for a while, "Our experimental team seems to have calculated something interesting, and I would like to invite you to take a look."
"Your experimental group?" Professor Li raised his head and looked at the hotel, and found that several of his incompetent disciples were still chatting with each other. At this time, he found that one of them was not there.
"No." Professor Zhao raised his eyebrows and said, "Professor Li's disciples are all here."
"There is one more person." Professor Li said in a deep voice, "Let's go, Lao Zhao, I'll show you today what makes a good seedling." One by one, what are you still eating here, hurry up. Something big happened to your experimental group!"
"Ah." Brother He said in a daze, "Boss, what big things can happen in our experimental group?" He scratched his head, thinking in his heart, what big things can happen in a marginal experimental group is rare.
But seeing that his boss had already walked towards the gate of the hotel, Brother He had no choice but to call a few brothers to follow the boss.
After walking out of the hotel, Professor Zhao asked, "Little Ma, what is it?"
Ma Bo said with a smile, "I can't say anything about this matter. It's better for you, the instructor, to go and see for yourself. It seems that some errors in the large eddy simulation have been found out."
"What method?" Professor Zhao took a deep look at Ma Bo, and he couldn't think of a solution after several days of continuous research.I was found out today, aren't you kidding me?
"It seems to be a linear transformation?" Ma Bo was stunned for a moment, and said to his tutor Professor Zhao with a wry smile, "Teacher, you know that I'm really not very good at mathematics."
Professor Zhao nodded, but did not speak.Is it possible to work out their errors with a linear transformation?He looked at Marbo and said, "Are you sure?"
"Yeah." Marbo nodded.
Brother He was still confused behind Professor Li. He didn't know anything, so he was called over.The brothers behind them were also confused, until they came to the front of the laboratory building, they put on their ID cards and walked into the laboratory building.
When he came to the laboratory of the experimental group, the first thing that caught Professor Zhao's eyes was a student who looked very immature.This student looks quite good, but a little short.Standing on the podium, different formulas are written.
At this time, Professor Zhao was deeply attracted by the calculation formulas on the blackboard. As the student on the podium wrote faster and faster, Professor Zhao's eyes became more and more active.
He muttered to himself, "That's right, that's right, I actually found the wrong value."
Ma Bo was also taken aback for a moment. He didn't expect that Wang Yun had written so many calculations just after he went out for a while.When Wang Yun stopped writing, he smiled at Ma Bo, and then saw so many pairs of eyes looking at him.Wei Wei was stunned for a moment, and said, "Uh, I can only calculate up to this point. All the wrong values must not be calculated now. But it is better to use linear transformation to find the wrong values, but the amount of calculation is relatively large."
Professor Zhao nodded, looked at Professor Li and said, "Where did you find this person?"
"People from Peking University's Mathematics Research Institute, you have made up your mind." Professor Li smiled and said, "If you dare to pay attention, believe it or not, Lao Yang will directly overturn your laboratory at the National University of Science and Technology."
"He dares!" Professor Zhao raised his eyebrows, then looked at Wang Yun, and the more he liked it, the more he liked it, and said happily, "Little classmate, are you from the Beijing University of Mathematics?"
"Yuanpei Academy." Wang Yun smiled shyly, "I haven't gone to Beijing University to study yet, and I will be a freshman in the second half of the year."
"..." Terrible, terrible.Today's students are already so evil, I think they didn't understand these things at all when they went to college.
"Are you planning to take the postgraduate entrance examination? Should the National University of Science and Technology consider it?" Professor Zhao looked at Wang Yun with a smile.
Wang Yun looked at Professor Li as if asking for help. At this time, Professor Li stood up and said, "Tell me what you think, how to use linear transformation to find the wrong value?"
"Because I thought of a problem today, the error in the value is still an error in the function after all, so I thought about trying to use mathematics to find the wrong value." When he said this, Wang Yun smiled embarrassedly, "I only found two, I'm sorry, and I'm bothering Brother Ma."
"No trouble, no trouble." It's too late for him to be happy now, although he knows that there is still a long way to go before completely finding out the wrong value.But two wrong values have been found, can the others be far behind?Certainly not!
Professor Zhao also nodded and said, "Your functional analysis is very good, and you also have a lot of research on fluid mechanics. I think you can learn about CFD. In this regard, the University of Science and Technology of my country is the first, who dares to say the second!"
Emmmmm......
What is the turbulence laboratory of Beijing University?The current professors are already so stupid in order to grab students?
"Put it down, don't go to the turbulence laboratory of Peking University to ask for data if you have the ability." Professor Li did not hesitate to expose his old friend, and he would only say that when he was so familiar with him.
"Okay, you are tired today, go back and rest early." Professor Li waved his hand, "Continue to search according to this idea tomorrow, and we must finish everything within two months."
"Hey." Professor Li's students responded and all dispersed back to their dormitories.
Wang Yun stepped off the podium and said to Professor Li and Zhao, "Professors, then I will go back to rest first."
"Go back quickly." After speaking, Wang Yun said goodbye to the two professors and left the laboratory.
Looking at Wang Yun's back as he drifted away, Professor Zhao said, "Old Li, you can't do this."
"Huh?" Professor Li sneered, "What kind of argument is that?"
"How can such a good seedling be placed in the marginal experimental group? In any case, it must be in the core experimental group—" Professor Zhao was very satisfied with Wang Yun, so he wanted to transfer Wang Yun to the core experimental group.
However, Wang Yun was brought by Professor Li. Without Professor Li's approval, it is really impossible for him to directly transfer people to the core experimental group.
Isn't this a slap in the face on the spot? !Professor Zhao definitely couldn't do this kind of thing.
"You have a good idea." Professor Li said as he walked, "That's what I planned too, but it doesn't work."
Professor Li sighed, "I didn't borrow people, but Lao Wan borrowed them. Before leaving, Lao Wanqian reminded Wan Wan not to touch core topics, or even handle core data."
"Why?" Professor Zhao and Professor Wan also knew each other, so he didn't quite understand.Given Professor Wan's personality, he definitely wouldn't say that.But this time, such a good seedling slipped away from under their noses, which doesn't make sense at all.
"Old Wan said, let's not delay his bright future." When he said this, Professor Li smiled wryly, "Princeton invited him to study at Princeton again and again, no matter what he said, he became famous at a young age. There are also great ones. In the future, why bother to conduct scientific research incognito like our group of bad old men."
"What can Princeton offer him, but our National University of Science and Technology can't give it?" Professor Zhao was a little unbelieving, "Why do you have to study abroad and drink foreign ink to be considered a talent?"
"Princeton can send him to the Fields Awards stage, but can you, UCAS?" Professor Li squinted at Professor Zhao.
"..." Professor Zhao snorted, "What's so great about the Fields Medal."
"But it is undeniable that if he returns to China with the halo of the Fields Medal, he will be different from the PhDs who stay in China." Professor Li said dumbfounded, "Otherwise, why do so many students go abroad to be gilded?"
The topic was a bit heavy, and the two professors glanced at each other, but neither spoke.
Indeed, the students who stayed in China must not have received as much attention as the students who returned from studying abroad before they produced results.Especially - Ph.D. students from world-class prestigious universities.
"It's not that I don't let him enter the core group, but after I let him enter the core group. Lao Wan is going to fight me hard." Professor Li sighed, "That's why I arranged him in the experimental group for data calculation. "
"I didn't expect it to be gold, and it will shine everywhere." Professor Li raised his brows and looked at the professor, "How about it, let me tell you, let me show you a real good seedling. How about this good seedling?"
"Okay, okay, okay!" Saying yes three times in a row, it seems that Professor Zhao is already very satisfied with Wang Yun.
