Hammer of Technology

"Dr. Ning, why don't you sit with me and let me go to the back?"

After Wang Jiaying was stunned, she stood up decisively.Ning Wei knew this girl, Jiang Chenshuang's roommate, when he went to help Jiang Chenshuang move things.

"Is this okay?" Ning Wei asked.

"Why don't you treat us to another meal in the dormitory?" Wang Jiaying said immediately.

"I invite you to eat ten meals. By the way, I will introduce you to a boyfriend. I will pester him every day to ensure that the agent will not fail the exam." Ning Wei said immediately. When he said this, he thought of Yu Xingwei who was still single .

"Deal!" Wang Jiaying replied quickly, then picked up the book casually, walked towards the back of the classroom, and Ning Wei also sat on it unceremoniously.

Everything was going well, Ning Wei glanced back, Wang Jiaying had just sat down, and the middle-aged professor who taught modern science came in from the front door of the classroom, coincidentally, this associate professor named Ning Wei from the Department of Financial Mathematics happened to be know.Well, the actual situation is that after staying in the Mathematics Research Center for a long time, Ning Wei has met most of the professors related to mathematics, so he naturally knows each other.

Ning Wei turned his head to look at Jiang Chenshuang beside him, and found that this silly girl was obviously a little nervous at this moment, and she didn't know where to put her hands. With his left hand in his hand, he sat upright and looked at the podium.

Out of the corner of his eye, he could see that the silly girl froze for a moment, subconsciously glanced sideways at him, then raised her right hand, picked up a pen and looked at the teacher on the podium.Xi Yuxuan, who was sitting next to classmate Jiang, saw the scene completely, then suppressed a smile, and looked at the podium.

There was nothing wrong with the three of them, but when Professor Shi was ready to see on the podium and coughed twice to prepare to give a lecture, he found that the atmosphere in the class seemed a little weird. Many people unconsciously looked in the same direction, even the former All the children in the row turned their heads and looked at them from time to time, and then they also glanced at the direction everyone was paying attention to. At first glance, there seemed to be nothing wrong. Just when they were about to give a lecture, they suddenly felt that there was a serious boy who looked familiar, and then After a glance, it was confirmed this time.

"Ahem, I said, what are you all looking at today? What's the situation? I said Xiao Ning, didn't Director Tian send you to inspect my teaching quality?" Professor Shi looked at Ning Wei and asked.

"Pfft, haha..." There was a burst of cheerful laughter in the classroom.

"It wasn't at the time. Professor Shi, I just suddenly felt that I needed to supplement my foundation in line generation. I heard that the line generation you teach is very good, so I came to listen to it." Ning Wei said seriously.

"Hiss, oops, what Xiao Ning said made me feel a little bit helpless today."

Professor Shi glanced at the girl beside Ningwei who was hanging her head, and smiled: "If you say that, you really can't beat me. Forget it, let's be sincere, I know you have been busy with supercomputers recently. I haven't been back for a long time about the matter at the center. Director Tian has mentioned it many times on different occasions, so I know why you came today. So I won't point you out. Later, in case there is something wrong in class, You are not allowed to go out and talk nonsense."

"Okay, students, please pay attention. After the two lectures today, everyone will usher in the long-awaited midterm exam. It just so happens that Dr. Ning Wei, who is well-known in our college, has come to the class. If you have studied before If there is anything I don’t understand about the content, there is an excellent teacher who can ask after class today. Professor Lu’s teaching assistants are usually active in the School of Mathematics, but they rarely have the opportunity to explain to our students in the School of Economics. You should catch up Take advantage of this once-in-a-lifetime opportunity, and don't let him run away easily."

After finishing speaking, ignoring Ning Wei's dumbfounding expression, Professor Shi opened the courseware in a serious manner, and started the class seriously: "Okay, now the class is officially started. The content of this class is the intersection and sum of subspaces. Direct sums, and isomorphic relations, everyone has already understood the basic concepts of linear spaces in the last class, such as the four basic subspaces, then when..."

"I'm at a big loss. I just wanted to come and see you, but when I had a mid-term exam, you said that class would be over later, wouldn't there really be a lot of people around me asking questions?" The girl beside him asked in a low voice.

Before classmate Jiang could say anything, a piece of manuscript paper next to him was pushed in front of classmate Jiang. Classmate Jiang glanced at it, and then silently pushed it to Ning Wei. Ning Wei took a look at it, and then felt dizzy.

Just as he was talking, someone asked him to help solve the problem, but looking sideways at the smiling face of the eldest sister in the dormitory with Jiang, Ning Wei had no choice but to let go of Jiang's little hand, and picked up the pen...

It turns out that it was wrong to come to show affection during class.

------------

225 Huaxia Mathematics Annual Conference

Facts have proved that students really can't be encouraged. From the break of the first class, Ning Wei's place was surrounded, and he couldn't talk to Jiang for a few more words.From Ning Wei's point of view, the content of Line Substitution B is really very simple. For example, there are only two operators, either addition or multiplication, but it obviously still troubles many students.

I thought it was twelve o'clock after the second class, and everyone should be hungry, but the pressure of the midterm exam was obviously greater than many students' pursuit of lunch, so Ning Wei was once again surrounded by more than 20 Jiang Chenshuang's classmates live.Of course, Professor Shi on the podium was not much better, and was also surrounded by students on the podium to ask questions.

It's just that after Professor Shi explained a few topics, he glanced at Ning Wei who was still surrounded, and then Shi Shi ran away, leaving Ning Wei trapped there.

"In this way, everyone, stop asking questions one by one, and tell me all the questions you don't understand, starting with this classmate." After another 10 minutes, Ning Wei clapped his hands and said when he saw that the situation was wrong.

Fortunately, the quality of the students at Yanbei University is still very good. Most of them have thought carefully and prepared before coming to ask questions, and some even wrote directly on the manuscript paper. Know the problems of everyone around you.

"Okay, I understand everyone's troubles. In this way, I will not answer them one by one now, but I will tell you two points first. First, most of the difficulties you just told me are concentrated in various transformations. I Let me first say that all changes in line generation are actually a combination of different orders of addition and multiplication, and the order is actually fixed. No matter how many dimensions, all transformations are solved by two operators in different orders. The difference is nothing more than How many steps."

"Second, everyone may not have a clear understanding of the concept of arrays. Because of the existence of arrays, the entire operation process seems to be difficult to understand. Regarding these two problems, the efficiency of such lectures is too low. I That’s what I think, today I will expand these two points that are not easy for everyone to understand, and then make a courseware, find enough sample questions, and prepare two lessons for everyone before the midterm exam.”

"I looked at your class schedule online. The midterm exam is the day after tomorrow. You have no class scheduled for 9.10 tonight and tomorrow. How about this? I will make this courseware before tonight, and then use this courseware to teach today and tomorrow I will give you an in-depth explanation in two nights, and the classroom will be set here for the time being, and anyone who wants to come and listen will be able to come. How about it?" Ning Wei directly suggested.

Everyone is still reasonable. In the time between classes, it is worthwhile to change to four lectures to explain.And as long as Jiang Chenshuang is still in class, he is not afraid of Ning Wei reneging on his debts.

"Jiang Chenshuang, you're really embarrassing. Then there's nothing else to say, everyone, let's leave, don't disturb Dr. Ning and Chenshuang to have lunch together!" The eldest sister in the dormitory, Xi Yuxuan, immediately stood up and said.

The crowd around finally dissipated, and student Jiang finally breathed a sigh of relief.

"How about we go have dinner together?" Jiang Chenshuang invited the sisters in the dormitory.

"Forget it today. We are afraid that Dr. Ning will be angry and won't give us a lecture. Let's talk about it after the midterm exam. Let's go first."

Finally, there were only two people left. Ning Wei was about to say something when he received a call from Director Tian.

"Hey, you're done with things over there, why don't you come to the institute to report, and go to class with your girlfriend first?"

The news spread quickly, and Ning Wei felt that Lao Shi was not a good person.

"Ahem, director Tian is like this, isn't it already past nine o'clock when you come back?"

"Oh, it's all trivial. Even if you don't come back today, I will call you. You are ready to go to Hangzhou with Lu Dongyi for a meeting tomorrow."

"Ah? What kind of meeting are you going to Hangzhou for?" Ning Wei was a little surprised.

"What kind of meeting? I wonder if you are a person who devotes himself to studying mathematics. The day after tomorrow is the annual meeting of the Chinese Mathematical Society. This meeting is organized by Zhejiang University. You can report directly to Lu Dongyi tomorrow."

"Isn't it? Well, Director Tian, ​​it's fine for Senior Brother Lu to go, and I'll forget about it?" Ning Wei really didn't want to go. He felt like home in the house in the capital just now, so he wanted to run outside again. Really not happy.

"You and Senior Brother Lu are both special guests of this meeting, how can you not go? And I have already asked for leave, why do you ask for leave? I told you that you have to go to this meeting even if you are not going, Senior Brother Lu! I have registered for you, your registration fee has been paid, and the meeting list has been confirmed. The plane at [-] o'clock tomorrow afternoon has been booked for you, do you dare not go?" Tian Dao's tone was full Hate iron but not steel.

"Oh, well, I see." Ning Wei could only compromise.

"Okay, that's it, I hang up."

Putting the phone in his pocket, Ning Wei spread his hands at the girl beside him and said, "Okay, I have to release the pigeons tomorrow night. Director Tian asked me to attend the annual meeting of the Chinese Mathematical Society with Senior Brother Lu. For three days in a row."

"That's a good thing, you go, the students can understand. Let's talk about it after you come back." Jiang Chenshuang replied.

"That can't be done. After I come back, I have passed the midterm exam. In this way, I will make the courseware today. You can come to me after class in the afternoon. I will explain it to you first, and then you will explain it to everyone. "Ning Wei immediately decided.

"Me?" Jiang Chenshuang pointed at herself in surprise, a little flustered.

"Yeah, I'm very clear about your line generation results. Don't worry, you can do it. And it's an advantage for you to talk about it, because you know more about the difficulties that need to be explained than me." Ning Wei took a picture He patted the girl on the shoulder to encourage him.

"How could I understand the difficulties better than you?" Classmate Jiang looked at Ning Wei innocently.

"Isn't this normal? Because I really don't feel that the course of line generation is difficult? And you are still learning line generation B. Let's put it this way, do you believe it or not? I read the questions in 5 minutes, and then I can get full marks with my eyes closed?" Ning Wei replied naturally.

Why can Tian be easily chatted to death by some people?Probably some words sounded like bragging, but I couldn't find any reason to refute, because this guy seemed to be so awesome.At least Jiang Chenshuang believed that Ning Weizhen could do it, so she didn't know how to refute it.

"Let's go, how many times have I told you. What you need most now is self-confidence, self-confidence, self-confidence! Isn't it just a broken line? You only have two classes in the afternoon, give me two hours, plus the money I dedicated The courseware will definitely let you master the whole line generation system!"

"But……"

"Don't be rude, a man spits and nails, and he must do what he says. You don't want me to break my promise in front of your classmates, do you?"

……

Facts have proved that human potential is really forced out...

It was a piece of cake for Ning Wei to make a difficult courseware for line generation B, and then to instill Jiang Chenshuang's understanding of the concepts of line generation from the shallower to the deeper.As he said, in fact, the so-called difficulties are nothing more than those conversion problems, which are too abstract, but in fact the rules and principles of line generation are very strong. Once you get started, basically all question types can be solved according to the corresponding principles. step derivation.

In short, in Ning Wei's opinion, Jiang's lecture at night was still very successful. Of course, this is also related to the fact that the courseware prepared by Ning Wei is sufficient and accurate enough to control the difficulties. For students who have already studied relevant knowledge systematically, the help is still great.

Of course, these are floating clouds. Seeing that Jiang was able to explain the courseware he had prepared in an orderly manner to seven or eighty students in the classroom, although he was a little nervous at first, after he really focused on the topic, he later It can be said that half of the speech is very fluent, and he can even start interacting with his classmates. This is what makes Ningwei the happiest, and he has a full sense of accomplishment.

This even made Ning Wei feel grateful towards Senior Brother Lu for a moment.If Lu Dongyi hadn't advised Jiang Chenshuang to handle the donation to his alma mater, Ning Wei felt that the probability of Jiang's progress would not be so great.Although in the end they will definitely agree to go to the podium, but it will definitely not have this effect.After the [-]-minute class ended, there was even applause in the classroom.

……

"Senior Brother Lu, don't you know that my Chenshuang was able to draw inferences when she was on stage to give a lecture. I almost thought she was a specially trained teacher with that kind of free and easy feeling. Of course, this also shows me that she did a good job. There is a little relationship, but the most important thing is that Jiang is too strong!" On the plane, Ning Wei chattered about Jiang's performance last night to Senior Brother Lu beside him.

This actually made Lu Dongyi very speechless, and even missed the time when everyone met and simply showed off their academic achievements, but the time was undoubtedly too short, which even made Lu Dongyi start to regret that day. Ning Wei asked to listen to the piano with him.

Not to mention that the artistic conception is gone, now that Ning Wei met him, he would be able to talk to him about how good his classmate Jiang was after a few words.More importantly, thinking of Director Tian's explanation, Lu Dongyi began to be jealous of the guy next to him. The little junior who used to know nothing grew up so fast that he was almost speechless.

"Can you stop talking about your classmate Jiang, don't you have any expectations for the upcoming Huaxia Mathematics Annual Conference?" Lu Dongyi couldn't help but said.

"Isn't it just a mathematics academic conference? What to expect?" Ning Wei was stunned and asked.

Thinking of Tian Dao's explanation, Lu Dongyi sighed in his heart and said, "At least you can meet great figures in the Chinese mathematics world, such as that Professor Qiu opposite. Isn't this worth your expectation?"

"Oh? Professor Qiu is also going to participate in this conference?" Ning Wei was a little surprised, because this Professor Qiu was about 73 years old.

"Otherwise, why do you think our director Tian asked for leave?" Lu Dongyi shrugged.

Ning Wei nodded thoughtfully. Although he doesn't know much about the mathematics circles in China, the conflict between the two big bosses Qiu Tian probably has been heard by every mathematics student in China. Yes, because there is no need to gossip at all, as long as the relevant courses are taken, the lecturers and professors in the class will often add a few sentences.

Of course, this kind of thing would never be explored.In fact, walking into this circle, Ning Wei knows very well that even the academic circle in China is not that simple.There are also factional disputes.But for Ning Wei, since he decided to build a mathematical theory for artificial intelligence as a breakthrough in mathematics, coupled with the addition of the turbulence algorithm, he has directly become a detached existence.

Because he doesn't seek fame or profit, he doesn't need to mix circles. He does research in the courtyard of Yanbei University, and the days when he has nothing to do with his classmate Jiang and show affection is actually quite suitable for him, and he has a Tian director in academics The big Buddha stood in front of him, and he maintained an excellent relationship with Jiangcheng University, so domestic academic disputes couldn't find him at all.

More importantly, the two conferences that made him stand out were both at the International Conference on Computer Algorithms. Although it is closely related to mathematics, it is also missing something.

The only thing that can be said to have affected Ningwei is probably the final report. Among the bloggers who questioned Ningwei on Weibo at the beginning, it is said that one of them was a colleague of him. Compare it.

Ning Wei didn't take this kind of thing to heart, and didn't even go into the doctor's name.His ideas are very grand, and he is really not very interested in the domestic ones.Moreover, in Ning Wei's simple cognition, the domestic academic circles should have a unified thinking and be consistent with the outside world.

Although influence is a bit illusory, it is actually a precious resource.If others have great influence in any field, their own influence will naturally be small, and influence directly involves the right to speak, and the right to speak involves the formulation of underlying standards.

This is why Ning Wei is more interested in applications than number theory.What he needs to study number theory is to find a mathematical method to solve the mystery, not necessarily a final result.

So Brother Lu's words actually made Ning Wei even more entangled, and even thought about going to Hangzhou to buy a return ticket directly, involving the grievances and hatreds of the big bosses, thinking about it made him feel dizzy, but unfortunately he knew that this might not be true Possibly, it is impossible for Lu Dongyi to let him mess around like this.

So Ningwei asked cautiously: "Then what should our attitude be when we meet Mr. Qiu?"

Lu Dongyi glanced at Ning Wei, and pursed his lips: "What attitude? Of course it is the attitude of the students when they see the teacher! Give respect, neither humble nor overbearing. What does the discord between teachers have to do with us as students? If it’s right, we should listen, if it’s not, we should argue with reason, we are doing research, we’re not in circles, we don’t need to be slick, respect science, just seek truth from facts.”

Ning Wei nodded suddenly, and said: "Senior Brother is still able to see clearly, I understand."

226 You Can't Understand

The plane landed at Hangzhou International Airport on time. To Ningwei's surprise, just as he walked out of the airport, he met Dean Kong of Jiang University and Professor Xu of the Department of Basic Mathematics of Jiang University, both acquaintances.Dean Kong’s help to Ning Wei will not be mentioned, this Professor Xu Chengwen is actually very good to Ning Wei, especially the direction of Professor Xu’s research is the direction of pde, after Ning Wei published the first After a dissertation, Ning Wei was also invited several times to read his doctoral student. In short, the sudden meeting still made Ning Wei very excited.

"Dean Kong, Professor Xu, have you just arrived?" Ning Wei happily came to the two professors as soon as he walked out of the domestic arrival station.

"Our plane is about ten minutes ahead of yours, but seeing that the organizing committee here is here to pick up your comrades, I know your plane will arrive soon, so I just waited for a while." Kong Mingde replied with a smile .

It was only then that Ning Wei noticed that the two big men were accompanied by two young men who looked more mature than him in suits, and one of them was holding an A4 paper with his and Lu Dongyi's names written on it. In my heart, I admire the organizing committee of the Huaxia Conference for being more humane than foreign countries. The two conferences he participated in, whether it was stoc or soda, the organizing committee never cared about the traffic problem. The two consecutive times were troubled by Professor Shen who sent him The assistant Feng Ge went to pick him up.

However, Ning Wei felt that if he went abroad to participate in the conference, he might not be able to enjoy this kind of treatment. After all, the external network felt that his popularity was not very good.

Before saying hello, Lu Dongyi had already walked to Ning Wei, nodded to Kong Mingde and Professor Xu, and said hello concisely: "Dean Kong, Professor Xu, good."

"Oh, Professor Lu, we meet again. The next time I have the opportunity to go to Jiangda University, let me know in advance. Whether it is for academic exchanges or to give advice on teaching work, we will sweep the bed and treat each other. I specifically criticized the last time. In the logistics department of the college, Professor Lu is here, and these people have not received any news, and they don’t even have a basic reception etiquette. The mistakes in work are too outrageous, don’t you mind.” Kong Mingde saw Lu Dongyi and smiled Hehe said.

Obviously, Dean Kong still cared about Lu Dongyi pretending to be a student and coming to win Ning Wei's heart away.At least one year has passed since the incident, and they still haven't let go of it, so they bring up the old matter again when they meet each other. Different people have different opinions on what they mean.

Fortunately, Lu Dongyi was not annoyed when he arrived, he simply nodded, and then replied a little dullly: "Academician Kong is polite, next time I really want to go to Jiang University, I will definitely go with Junior Brother Ning , it will not be counted as a visit at that time, just go home and have a look, if you accept it or not, then you will see outside."

Speaking of this, Ning Wei felt a little ashamed, and quickly smoothed things over: "Haha, let's not talk about the past when we finally met, we should look forward to the future, it just happened to happen, why don't we just take a car to the hotel, Talk on the road, talk on the road."

"It's okay, Ning Wei, we can meet anytime, you meet the teacher, just go with them in a car, chat more, I'll take another car, everyone will come, it's not good Let the car run empty." Lu Dongyi waved his hand and said.

In this way, the bosses on both sides decided how to go to the hotel in a few words. Of course, Ning Wei also felt how fierce the verbal confrontation was under the smiles of the two sides. Look at the trouble...

But Ning Wei still regretted waiting for Dean Kong's car, especially when he was pushed by Professor Xu and sat in the back row with Dean Kong.

"Ning Wei, congratulations first!" Kong Mingde said as soon as he got into the car.

"Congratulations? Dean Kong, what are you congratulating me for?" Ning Wei was a little confused.

"Did Tian Yan really not mention it to you?" Kong Mingde asked in surprise.

"No, Director Tian asked me to hold a meeting." Ning Wei replied.

"Hehe, let's not talk about this for now. I said Ning Wei, we have met, and you plan to hide some things from us?" Kong Mingde immediately changed the topic.

Hearing this, Professor Xu, who was sitting in the co-pilot, also turned around and gave Ning Wei a half-smile.

"Forehead?"

Ning Wei thought about it for a while and probably understood what Dean Kong was talking about. He didn't choose to pretend to be stupid, but just smiled shyly: "Dean Kong, look at what you said, if I have something to hide from you, then It must be a good thing for Jiang University. Don’t you know me? There is nothing else good, just nostalgia.”

"Well, I really believe this! There are really good things I think about our Jiang University, that is, toss us old guys to hold several meetings, and have been suspicious for half a month. Finally, I found out that you are the only one in the middle. Make trouble." Kong Mingde glanced at Ning Wei, and said indifferently.

"Haha, why don't we stop talking about this, what happened when you said congratulations to me just now? How about you tell me about it, so that I can be mentally prepared." Ning Wei said cheekily.

Kong Mingde smiled, and said: "Tian Yanzhen can't bear to tell you, so we don't have much to do, and you will know tomorrow. Guess Lao Tian is still staying in the office at this time and secretly having fun." Well. I have something serious to discuss with you. The Department of Information and Computing Science of the college plans to offer an introductory course on the basics of artificial intelligence mathematics and physics in the base class, which includes compression and transmission in the era of big data, and artificial intelligence learning algorithms. Content."

"After we brought this matter up at the meeting, it was also recognized by some companies. For example, Director Lu of the software laboratory contacted Huawei and some domestic technology companies, and these companies even sent high-level technical and human resources to participate. After our discussion meeting, Huawei, as a representative of the enterprise, also agreed with our ideas very much, and believed that our curriculum should indeed keep pace with the times."

"So now I want to invite you to join our new course preparatory committee. Just now you said that you are a nostalgic person, so you shouldn't refuse, right? I think so. After the course is arranged, it will be an elective course first. According to the final course Determine the degree of difficulty to determine the credits, if the effect is good, then it will be upgraded to a professional compulsory course. What do you think?"

Ning Wei was really embarrassed to refuse when the former dean brought the words to this point, so he could only nod his head and said, "It's okay to join the committee, but you shouldn't go to Jiangcheng often, right? You know, my side recently It's actually pretty busy."

"Haha, don't worry, because it is an undergraduate course, so you don't need to go too deep. The main purpose is to let students have a foundation for these concepts and stimulate students' interest in this area. We plan to formally introduce this course after the start of the next year. This course will be included as an elective course from the sophomore to the junior year, and there is still more than half a year of preparation time. When communication is needed, it can be solved through remote meetings." Kong Mingde said with a smile.

"Then there's no problem." Ning Wei readily agreed, and he wasn't bothered about other things, as long as he could bypass the matter of March first.

"Okay, then it's settled. Later, I will ask the committee to send you the letter of appointment. By the way, Ning Wei, have you considered what to do after graduation?" Kong Mingde asked again after finishing the business.

Ning Wei shook his head, he really hadn’t thought about this aspect, it’s only been two months since he officially got his doctoral student card, no matter how you look at it, it’s too early to think about graduating now .
