God of black technology

If you want to ask Wang Yun whether he wants to join the core experimental group, then the answer must be to join, after all, it is the core experimental group.How could he not want to join? In the core experimental group, he would accomplish a lot.But the problem is that he can't join the core experimental group at all now.That's right, you just can't join.

It's not that he doesn't want to join, but that he can't.He has his own ideas, now after joining the core experimental group.It will definitely be restricted from going abroad, especially the discipline of morality, which is itself more advanced than other countries.What's more, Wang Yun wants to study abroad after finishing his undergraduate degree, absorb the experience of foreign advanced disciplines, and then return to China.In the experimental group, Professor Zhao and Ma Botao looked at Wang Yun.

Obviously, they were all waiting for Wang Yun's answer.

And Wang Yun was also silent, after a while.Still no one spoke, Ma Botao looked at Wang Yun and said with a smile, "What's wrong? Are you struggling?"

"If you join the core experimental group, I believe the professor will not let you suffer." When he said this, Ma Botao looked at Professor Zhao next to him.At this time, Professor Zhao nodded slightly, looked at Wang Yun and said, "If you join the core experimental group, after you graduate from university, I can let you directly study for a direct doctoral degree at UCAS. No matter which professor you are, I believe you will be welcome to join. of."

Wang Yun's lips moved. To be honest, Professor Zhao's condition is very attractive.After all, any professor is fine, and it is also known as the elite of the military and the best military academy in Huaguo.Some special research can only be carried out by the research laboratory of the National University of Science and Technology.

"Professor." Wang Yun rubbed his nose and smiled, "I'm afraid I can't agree to the professor's invitation now." He carefully looked at the professor's face, and found that the professor's face was slightly stiff, and then returned to normal.It seemed that even if he rejected the professor, the professor would not be too angry.

"Oh?" After hearing Wang Yun's refusal, Professor Zhao smiled and asked Wang Yun, "What do you think? Or, may I ask, why did you reject me?"

Professor Zhao was also very curious, and he gave very good treatment conditions.But after Wang Yun hesitated, he still rejected him.It seems that he is also tempted.But Professor Zhao wanted to know why Wang Yun rejected him.

"I thought about it, and I decided to study abroad." Wang Yun smiled a little embarrassedly.

"Why do you have to study abroad?" Professor Zhao folded his hands on his chest and looked at Wang Yun. "I heard that you rejected the invitation letters from Princeton, Harvard and many other world-renowned schools, but you want to study abroad. With such a plan, why didn't you go abroad in the first place?"

"Because it is better for me to study in China at this stage." Wang Yun thought for a while, and decided to explain to Professor Zhao honestly, "But it is undeniable that many experimental subjects in famous foreign universities are much more advanced than those in China. When I go abroad, I’m afraid I can only do some theory, and I can’t even learn more advanced experience. So when I plan to take the postgraduate entrance examination, I will go to Princeton or Harvard. Whether it’s the Institute for Advanced Study in Princeton or Harvard. The Institute of Advanced Study is also good. They are indeed much more advanced than domestic ones.”

"So, you plan to return to China after learning advanced foreign experience and technology abroad?" Professor Zhao asked casually when he heard Wang Yun's eloquent words.

Wang Yun didn't deny it, nodded and said, "That's right, that's what I thought. So I rejected Professor Zhao, and I hope you won't be angry."

"There's nothing to be angry about." Professor Zhao laughed and said, "My purpose is the same, to build a better Huaguo. But the means are a little different. I personally don't advocate studying abroad. Or say , I personally think it’s nothing to study abroad or not to study abroad.”

"But for people like you, I now think that you are quite interested after studying abroad." Professor Zhao stood up, patted Wang Yun on the shoulder, and said earnestly, "After going abroad, learn other people's advanced technology. After returning home, there is a lot to do!"

"Thank you, Professor Zhao, for your understanding." Wang Yun smiled, and Professor Zhao stopped and said, "It's not a question of understanding or not." When he said this, Professor Zhao paused.

"That's right." He patted his head and said, "I almost forgot about the business."

"You said that we are now doing large eddy simulation instead of doing turbulence models and taking the Reynolds average equation?" Professor Zhao looked at Wang Yun, "tell me what you think."

Finally getting to the point, Wang Yun nodded and looked at Professor Zhao and said, "When I was sorting out the data, I found something that wasn't quite right. If I didn't guess wrong, it's part of the core data, right?" Wang Yun Yun looked at Professor Zhao.

Professor Zhao didn't speak, just nodded slightly.

It is indeed not easy for this student to sort out the data and find something wrong.

"So, does it have anything to do with suggesting that we use a turbulent flow model?" Professor Zhao smiled, "Now the Reynolds average equation, that is, the average NS equation, before the NS equation is solved, the error value should be worse than that of the large eddy simulation. More?"

"No." Wang Yun shook his head, "I think the turbulence model is more accurate than the large eddy simulation. Nowadays, ballistics is the most important thing in ballistics, and ballistics is nothing more than flow field, turbulence, etc. .”

"I suggest that the same is true for building a turbulence model, which can simulate the trajectory of a ballistic trajectory." Wang Yun smiled. "The best trajectory is nothing other than the one that the opponent cannot intercept. According to this idea, turbulent flow is more useful than large eddy simulation." When he said this, Wang Yun smiled embarrassedly, "Professor, these are just my humble opinions, so don't take them to heart."

Professor Zhao did not speak, but was thinking about what Wang Yun said just now. After a while, he nodded and said, "You are right. It is indeed better to build a turbulence model. But the average NS equation is not the same. It is not easy to choose, and the amount of calculation required is too large. Who among us high-level physics people can have such a great ability to solve the average NS equation?" When he said this, Professor Zhao looked at Wang Yun, "I am afraid that even Neither can you."

Wang Yun smiled awkwardly, of course he can't. The NS equation is not so easy, and taking the average NS equation is not so accurate at all. If the NS equation can be solved, then the Reynolds average equation can naturally be used.

The problem is, no one can unravel its mystery right now.

"I have considered the conclusion you made a long time ago, but in the end I chose the large eddy simulation. I hope you can understand." Professor Zhao looked at Wang Yun with piercing eyes.

Wang Yun thought for a while, then nodded and said, "I understand."

Professor Zhao smiled, "I didn't need to explain it to you, but you are one of the smartest students I have ever met. So, I think it is better to explain some things to you."

Wang Yun said gratefully, "Thank you, Professor Zhao." If Professor Zhao didn't come to explain this matter, he might still be troubled by this matter for several days.After all, in his opinion, the turbulence model is much better than the large eddy simulation.But the problem is that when Professor Zhao asked him if he understood.

He understood in an instant that this subject was not in a hurry, but required precision.Therefore, Professor Zhao and the others would rather go slower than make a fuss about accuracy.Combined with the impermanence of turbulence, it seems that it is very difficult for Professor Zhao and the others.

After Professor Zhao left, Wang Yun erased the blackboard.Although today is a day off, it is somewhat embarrassing for others to see him calculating math problems in the experimental group.

After Ma Botao sent Professor Zhao back to the office, he walked to the door of the experimental group.Seeing Wang Yun washing his hands, he said with a smile, "Are there any questions now? The teacher approves, and I will tell you everything I know, and I can talk endlessly."

Wang Yun glanced at Ma Botao and shook his head, "I don't have any doubts for the time being." When he said this, Wang Yun laughed, "But the workload in the future will definitely increase a lot."

"Isn't this inevitable?" Ma Botao stretched his waist, "You are still young, you have already received such a big subject when you first came into contact with it, and you will be successful in the future, so you must not forget your brother."

"Hey." Wang Yun and Ma Botao are almost familiar with each other now, so they jokingly said, "Then Ma has to take good care of me now, maybe he can lead Ma to do some big projects in the future."

"Boy, you have already learned how to eat Naka." Brother Ma said with a smile, "Okay, please go to the cafeteria to eat. You can order whatever you want."

"Small cafeteria?" Wang Yun's eyes flickered at Brother Ma.

The small canteen needs to pay by itself, but all members of the large canteen research team do not need to pay.

"It's too greedy." Ma Botao said, covering his face, "If you continue to eat like this, you will almost eat up my monthly allowance."

"It's okay, it's okay." Wang Yun patted Ma Botao's shoulder and said, "In order to bring you into a big project in the future, Brother Ma, you will not refuse, right? You can't just look at the immediate benefits, you have to look at it in the long run. "

No matter what, let's draw a big cake first, and talk about it after a meal.

"Okay." Ma Botao didn't know whether to laugh or cry, "Let's go, please eat in the small cafeteria, and you can give me a little less. This is my wife. If I can't marry a wife in the future, I will make a fuss in your Mathematics Research Center building." ah."

"I can't run, I can't run..." Wang Yun said as he walked into the small cafeteria excitedly.

After eating, Ma Botao and Wang Yun returned to the dormitory.

Brother He looked at Wang Yun in a daze, "When I got up today, I saw that you were not here. Where did you go?" When he said this, Brother He took a look at Wang Yun and continued, "I am here today. I didn't see you when I was eating in the cafeteria at noon? Have you eaten yet?"

"Eat." Wang Yun smiled, "I went to the laboratory today, I have something to do."

"I'll go!" He Ge's anger burst out all of a sudden, "That guy surnamed Ma is oppressing you again?"

"No, no." Wang Yun hurriedly stopped, "It's a private matter."

"What's private?" Brother He looked at Wang Yun curiously. What private matter could there be in the laboratory?He really hadn't heard that there was a private matter in the laboratory.

Who the hell wants to stay in the laboratory every day, scientific research dogs are also human, and they also want to let the wind go!

"I'm doing research on Zhou's conjecture." Looking at Brother He's suspicious eyes, Wang Yun spread his hands and said, "The main reason is that I have some inspiration, and the laboratory is on holiday again today. I thought, staying alone in the experiment In the lab, study it carefully. Unexpectedly, Brother Ma also went to the laboratory, and I even gave him a meal in the small cafeteria."

When talking about this, Wang Yun smiled, "Brother Ma is quite a good person." Speaking of this, Wang Yun looked at Brother He and asked, "Brother He, why do I feel that you and Brother Ma are not getting along? ah?"

"That guy!" Brother He said, clutching his forehead, "He's just a devil. Forget it, I won't talk to you about it."

Brother He sat on the bed and played with his mobile phone and said, "Today is off, where are you going to eat tonight?"

"Brother He isn't eating in the cafeteria tonight?" Wang Yun glanced at Brother He with a hint of doubt.

"Who wants to eat in the cafeteria every day." He sighed and said, "Scientific dogs are also human, right? Humans have desires, right. I just want to eat something delicious right now."

"I didn't see it, Brother He." Wang Yun said with a smile while reading, "You are also a foodie."

"What do you mean I am too..." Brother He was excited, "I was originally a gourmet who was delayed by scientific research, you know?"

Well, Brother He, just be happy yourself.

What else could Wang Yun say, of course he didn't say anything.Just watch He Ge quietly...

In the evening, Wang Yun originally wanted to study number theory, but unexpectedly, Brother He directly pulled the dormitory and said, "Don't stay in the dormitory every day, the technical house can't change the world. You should go out and relax..." Just When I went out, I met Ma Botao who was also going out.

"Where are you going?" Ma Botao looked at them in a daze and said, "Tomorrow's task is relatively heavy, and there may not be much rest time in the future. Planning to go out to play at night?"

"..." Brother He's mentality exploded. He almost felt that Ma Botao must have installed a camera in their dormitory.Otherwise, how could it be possible that Ma Botao went out as soon as they walked out.It was such a coincidence that he didn't believe it at all now.Brother He said in a broken voice, "We're going to go out for dinner and visit the night market by the way."

Wang Yun coughed lightly, "Brother He is going to let the wind go."

"Oh." Ma Botao nodded, glanced at Brother He, and then at Wang Yun, "How many of you?"

"Just the two of us." Brother He cursed in his heart, but on the surface he said in a very doggy manner, "Brother Ma, are you going?"

"Are you treating me?" Ma Botao looked at Brother He with some surprise in his eyes.

"..." I, Fat Tiger, just want to hit someone now!Brother He took a deep breath, nodded heavily and said, "That's right, I'm treating you!" He bit the word 'treat' very hard.

"Okay." Ma Botao said amusedly, "Let's go, I just need to supervise you, and I can't let you play too crazy tonight. Otherwise, I won't be able to take care of it tomorrow."

Emmmmm......

Wang Yun saw that Brother He's face became like a pig's liver, extremely purple.

He thought about it, probably Brother He couldn't help but want to hit Brother Ma hard.

The three of them walked out of the gate of Xigong University as usual. At this time, the night was gradually falling, and the sunset was stretched very long in the sky.Wang Yun was very pleased with the smell of smoke and fire. Wang Yun swallowed his saliva, looked at Brother He next to him and said, "Where shall we go for dinner tonight?"

Brother He took out his mobile phone and looked at it and said, "I don't think it's all right." When he said this, "The restaurant next to the school is just like that."

"Then where do you want to eat?" Ma Botao put his hands in his trouser pockets and looked at Brother He.

"Hmm..." Brother He took out his mobile phone and said, "Let's go to the city center to eat. I saw a pretty good restaurant."

"Okay." Ma Botao didn't say much, he didn't have any special obsession with what to eat, unless it was really hard to swallow, otherwise he was not picky about food.

Wang Yun nodded and followed.As soon as he took a taxi, Brother He turned his head and said to Ma Botao, "You pay."

"Pfft..." Wang Yun couldn't help it, and burst out laughing, Brother He is too cute, right?

"Okay." Ma Botao shrugged his shoulders indifferently, "I'll pay if I pay."

Anyway, it's not a big deal, I got in the car.The three came to the urban area, and now the entire urban area is brightly lit.The sky hadn't completely dimmed yet, but the lights of the city had already shone on the road.Wang Yun took a breath, and after Ma Botao paid the fare, the three of them went forward to look for food.

I don't know how long they walked, but they still haven't reached the restaurant that Brother He mentioned.

Ma Botao raised his eyebrows, looked at Brother He and said, "I said, Xiao He, you are not a road idiot, are you?"

"..." Brother He just wanted to tear Ma Botao apart, he rolled his eyes and said, "You're a road idiot, your whole family is a road idiot!"

"What's the matter?" Ma Botao glanced at Wang Yun, and Wang Yun was also a little speechless with his bewildered expression.

In the end, when they finally came to the door of the restaurant, they realized that this is what the hell—they have to wait.

After getting the number plate, Ma Botao said with emotion, "It's still waiting for so long for a meal that can be settled in the cafeteria." He sat on a chair outside the store, "I don't know how long the wait will be. "

"It shouldn't be too long." Wang Yun just sat down and looked forward, Brother He also sat beside Wang Yun.

"I read the reviews, and it's definitely the best restaurant here." Brother He said here, glanced at Ma Botao and said, "If some people think that the canteen is better, then go to the canteen to eat."

Ma Botao looked at Brother He, and said dumbfoundedly, "I said Xiao He, why are you making trouble with me?"

"Hmph!" Brother He turned his head and muttered, "Zhou Papi is even worse than you! You are simply a devil."

"I said, Xiao He, your vocabulary is relatively scarce." Ma Botao looked at Brother He with a smile.
