Tech Hammer

Lu Dongyi's meaning is very simple.

Ning Wei wanted to go through all the trouble, but he couldn't get past his senior brothers.

Who can hang out in this courtyard and usually has a calm temper? Who is not an arrogant person?

Ning Wei is even more so.

If we lose this time, I think my junior brother will naturally feel at ease.

Yes, Ning Wei has proven his ability, but it is mainly in the research of NS equations, and it is not the results he achieved at the Institute of Mathematics. Daily academic discussions have also proven that Ning Wei has a very solid foundation in mathematics and is involved in many fields.

But when it comes to solving mathematical problems specifically, it is actually a different field. It requires not only the mastery of mathematical concepts, but also a generalized thinking model and comprehensive ability and quality.

In particular, the questions asked by those Ph.D. brothers were very unusual and covered a wide range of topics.

Lu Dongyi probably had mixed confidence in Ning Wei.

Because Ning Wei's dazzling resume happens to be a shortcoming in mathematics competitions.

But as soon as he finished speaking, he saw Zhou Yanping walking out of the classroom with a stack of draft paper and a dejected look on his face.

This immediately attracted the attention of several professors.

"What's wrong? Xiao Zhou, are you out now? Don't you want to keep an eye on me?" Tian Yanzhen asked.

"Ning Wei has solved both the questions I asked for." Zhou Yanping said with a sad face.

"Oh? So fast?"

Lu Dongyi subconsciously picked up his phone and looked at the time. Only 35 minutes had passed since the beginning of the problem solving, and each question took an average of 17 minutes and 30 seconds.

"I just reviewed his problem-solving steps. There is no problem. It's a standard problem-solving idea. It took about twenty minutes to solve the first problem, and only ten minutes to solve the second problem. It took me another five minutes to check the answer. ." Zhou Yanping said dejectedly.

It is understandable that these people must have researched the answers when choosing the topic. Five minutes is indeed enough to judge whether Ning Wei's problem-solving steps are standard.

"Show me." Lu Dongyi stretched out his hand.

Zhou Yanping directly handed the paper Ning Wei filled with answers to Lu Dongyi.

The first sentence in the title: "Assume that the sphere is in a two-dimensional state and three points are randomly selected on the surface of the circle. The probability that the triangle formed contains the center of the circle is one quarter..."

After carefully reading through Ningwei's subsequent problem-solving process, Lu Dongyi handed the problem-solving process in his hand to the professors next to him.

Everyone began to circulate it quietly. After a while, Professor Xiao smiled and patted Zhou Yanping on the shoulder without saying anything.

Lu Dongyi glanced at Ning Wei, who was still immersed in writing in the classroom, shook his head, sighed, took out his mobile phone, walked to a quiet place and started making calls.

"Hey, Teacher Lu, do you have the phone number of the management office of our School of Art? Oh, nothing. I want to know who is in charge of the professor on the second floor next to the Hongliu Building. I have something to ask. Ask that teacher. Okay, I'll wait for his call, please."

…

Soon, several professors heard a cry from across the classroom door: "Hey, where are the questions that I thought were so difficult? Please, can the senior fellow students put a little more care and effort when setting the questions? You guys can do it." I bet on four questions that challenge my writing speed, who are you looking down on?"

Then I saw several of my doctoral students walking out of the classroom one by one with complicated and unspeakable expressions on their faces.

Standing outside the classroom, Zhou Yanping's expression became even more exciting when he heard those words. He changed back and forth several times from green to white, and then from white to green again...

Even so, Ning Wei, who finally walked out of the classroom, had a look of displeasure written all over his face. He looked like he wanted to say something more, but when he saw so many professors there, he still held it back.

"Ahem, is the gambling over? Xiao Zhang, did you answer the questions without any problems?" Professor Xiao asked.

Dr. Zhang said nothing and nodded.

He had been standing next to Ning Wei watching him answer the questions, so when Ning Wei finished writing the last stroke, he didn't need to check at all and knew that there was nothing wrong.

The key is to check the time after solving the problem. It only took 70 minutes in total.

It’s true that there is almost no time to think, and almost the entire process is spent writing proofs.

"You mean Ning Wei won?" Tian Yanzhen asked?

Several fellow doctors paused, then nodded dejectedly.

"Ning Wei, go to my office at four o'clock."

Tian Yanzhen confessed, then turned to the other professors and said: "Okay, let us old guys disperse. Let them handle the affairs of the young people by themselves. Our witnesses have also done the same , don’t care about anything else.”

Xiao Liang said, "Hey, Lao Tian, ​​I just happen to go sit in your office."

"Okay, let's go. Lao Li is coming over too. We haven't had a cup of tea together for a long time. Someone over there happened to have given me two bags of good tea. Let's have a cup together?"

"Okay!"

…

Soon, the professors dispersed.

As Tian Yanzhen said, the bet has already decided the winner. The next step is for young people to solve their own problems. The presence of professors like them has nothing to do except make the doctoral students in the hospital more embarrassed. Other uses.

You can't really listen to Ning to straighten out the nonsense.

Whether these doctoral students are just messing around, the supervisor naturally knows it in his heart. If he really had nothing to do every day like Ning Wei said, he would have been dragged to have a heart-to-heart talk with his supervisor a long time ago.

But after the professors had all left, Ning Wei lost all his reserve and asked directly: "Brothers, let me ask you this, is it only natural that you are willing to accept defeat?"

Lu Dongyi watched silently from the side. Sure enough, the junior brother was still very awake and knew that persimmons should be picked softly. He was still a little cautious when the professors were around.

Zhou Yanping said in a low voice: "Stop talking nonsense, just tell us what you want us to do!"

Ning Wei rolled his eyes and said with a sneer: "Then I'm not polite. Senior Brother Zhou, from this year onwards, as long as Senior Brother Lu and I are in the courtyard, the task of bringing meals to Professor Lu and me will be handed over to me every day at noon and evening. It’s your turn. Don’t worry, I don’t ask for a full banquet, but before you start the meal, please come and tell us what we want to eat.”

"Ahem... I won't use it!" Lu Dongyi finally couldn't help but interjected.

"No, Senior Brother Lu, as they said, you can do anything. It's the same as bringing one, but what's the difference between bringing two?"

"I……"

Zhou Yanping was a little annoyed, but before he could get angry, Ning Wei asked: "What's wrong? Senior Brother Zhou, don't say you were joking when you said you wanted to bet with me just now? Don't say I won't give you a chance. I'll give you a month." It’s time to ask a few more difficult questions, but at least for this month I’ll be bothering my senior brother with food.”

"If you're going to eat, you're going to eat! Don't tell me I can't afford to lose. Let's see!" Zhou Yanping waved his sleeves and left.

Ning Wei's eyes drifted to Senior Brother Luo: "Well, Senior Brother Luo, Senior Brother Lu and I will have to worry about the sanitation work in this office from now on. We, Professor Lu, are more particular about it. We are afraid that the cleaning aunt will mess up what we write. Now, it’s definitely okay for you to come, right? Like Senior Brother Zhou, you can also pick a few more questions for a month first!”

Senior Brother Luo nodded and said, "Oh, it's just cleaning! That's okay, I'll come half an hour earlier every morning from now on. I'll go and do some work first!"

"Wait a minute, everything must be based on the satisfaction of our Senior Brother Lu. You have to get some snacks. If Senior Brother Lu thinks that you are not cleaning well, I will lose my temper." Ning Wei said seriously.

This sentence made Senior Brother Luo look at Lu Dongyi affectionately before leaving.

Lu Dongyi raised his head and looked into the distance. Combined with Professor Xiao's words before, and hearing Ning Wei's explanation, he felt like it.

But Lu Dongyi also believed Ning Wei's words. He was indeed not very good at dealing with girls. But it's obvious that this guy is very good at dealing with these Ph.D. brothers from the Institute of Mathematics.

Ning Wei had already looked at Senior Brother Zhang.

Senior Brother Zhang rushed to answer: "Well, Ning Wei, I'm not asking you any questions! And let me tell you first, I don't like washing things, I won't wash anything!"

Ning Wei nodded and said: "Oh, that's okay. We still need a water fetcher. It's okay to go twice a day to help us get hot water, right? It's okay. It's a month. If Senior Brother Zhang wants to find some questions You can also practice with me."

"Junior brother is mighty. What he said is right. What about fetching water? Leave it to me." Senior brother Zhang patted his chest and said.

"As I said before, you have to get water immediately. If Senior Brother Lu finds the bottle empty when he wants to drink water, I will go to Senior Brother Zhang to chat with you! Don't say I'm looking for trouble then! , By the way, our water bottle seems to be empty." Ning Wei added.

Senior Brother Zhang: "..."

…

Finally, each of the senior brothers arranged their errands and left, and the office returned to its usual quiet state. Lu Dongyi sat in his seat with a complicated expression, while Ning Wei acted as if nothing had happened and began to sort out the mathematical notes he had written these days.

"Ning Wei!" Lu Dongyi sighed in his heart and said.

"Well, please tell me what Senior Brother Lu has ordered!" Ning Wei immediately raised his head and at least looked at Lu Dongyi with respect.

"If there is something going on between our senior brothers, why don't you just tell me? I really want my senior brother to help you find that female student, so you don't have to go around the bush." ​​Lu Dongyi said straightforwardly.

"Huh? What kind of female student? Senior Brother Lu, please don't talk nonsense. I don't have any sense of frivolity. I really just see a few Ph.D. seniors who are too busy every day and can't stand it!" Ning Wei stopped. With the movement of his hands, he raised his head and said seriously.

Ha, as expected, he is still arrogant.

"Hey, look what happened. I thought you were in a bad mood because the female student who played the piano hadn't played the piano in the past two days, so I called the teacher at the school office and later called the management. The teacher on the second floor has contacted me and is going to take you to understand the situation after you come back from Director Tian. Since you are not interested, you might as well go alone." Lu Dongyi shook his head and said with his He stated in an extremely plain and honest tone.

Ning Wei paused his hand, blinked, and then said with a look of realization, "Oh, the female student that senior brother mentioned, I almost forgot if you didn't tell me! Then I have to go." , the key point is that this is not a question of whether I am interested in her or not, I just think that if she is really a student of Yan University, she should not be like that! Our school has so many grants and scholarships, as well as the school hospital, a girl You can’t just ignore frostbite on your hands and not treat it, right?”

How to say this? Lu Dongyi only felt that Ning Wei's explanation was too reasonable. There was only one question, what does it have to do with you whether he can be cured or not?

Of course, Lu Dongyi didn't say this, and it had nothing to do with emotional intelligence. It was just that he didn't want to have another sudden thought and cause any mess.

The situation has become obvious. This junior fellow student is not very happy. He dares to directly provoke all the PhD fellows to be unhappy. However, he can still do it within the scope allowed by the rules. At least this is a harmless bet. The professors won’t think anything is wrong, let alone interfere too much.

We are all majoring in mathematics, so we are not allowed to discuss various difficult problems?

Considering that Ning Wei could not be allowed to tinker with some super mathematical problems to continue tossing his Ph.D. brothers and make everyone autistic, Lu Dongyi decided to remain silent and let Ning Wei continue to maintain his shyness.

But Lu Dongyi stopped talking, and Ning Wei didn't let him go. Although he seemed to have lowered his head and continued to sort out his notes, he suddenly asked in a nonchalant tone: "Brother Lu, are you talking to that teacher?" What time is the appointment?"

Lu Dongyi replied: "It's four-thirty. It doesn't matter if it's earlier or later. We'll go there when you come back from Director Tian's report."

"Well, no problem! It's only three o'clock. I still have time to finish all these notes." Ning Wei answered, and then he seemed to be very attentive and began to process and copy what he had written on the draft paper these days. Countless formulas...

…

At four o'clock in the afternoon, Ning Wei arrived at Director Tian's office on time. The professors had already dispersed, leaving a few cups for tea unpacked.

Ning Wei was about to help pick it up, but Tian Yanzhen stopped him: "Okay, I didn't ask you to show your courtesy. What have you been busy with these days? Have you started researching on the proposition you reported before?"

"Report to Director Tian, ​​a framework has been built. If you want to take a look, I will send it back to you." Ning Wei replied immediately.

"Okay, don't be so formal. There is no need to send me the framework. When your project is approved and you are ready to start writing the final report, come and report to me. The main reason I called you here is to say that you are reckless. Senior brother is an honest person. If you have any ideas, just tell him. If you can help, I will definitely not refuse." Tian Yanzhen educated him angrily.

"Oh, actually after getting along for a long time, you will find that I am quite honest." Ning Wei said honestly.

Looking at Ning Wei's appearance, Tian Yanzhen thought of the Weibo posted by this little guy, and also thought that Lucason Friend had probably never seen this kid look like this before, and he couldn't help but feel a surge in his heart. Feeling a strange emotion, he smiled and said: "Okay, don't boast about yourself. There is competition in academics. Honesty is not necessarily an advantage. You just need to be honest when doing academic work."

"In addition, I told you, Senior Brother Lu. If you really like to listen to other people playing the piano, the hospital will make arrangements and try to invite the female pianist to come and play for you for a while every day. But the payment will be approved by you. Your research funds will be deducted! Don’t bother with messy things in the future, you have to bully those senior brothers who are not as talented as you."

"I do not……"

"Okay, don't argue, go and do your business!" Tian Yanzhen waved his hand and said.

"Okay, goodbye, Director Tian." Ning Wei nodded, then turned around and left Director Tian's office.

Tian Yanzhen watched Ning Wei walk out of the office, and suddenly felt that if he had known that there would be such a story, he should have called the child to Shuyuan a year earlier and asked Lu Dongyi to take him around...
