Hammer of Technology

"Senior Brother Lu, don't worry about these details. Aren't Peking University and Jiang University both schools in our Great Huaxia? What is a little computing power? By the way, Senior Brother Yu, you've worked hard. Put your luggage in the room over there first." After reacting, Ning Wei enthusiastically stepped forward to take Yu Xingwei's luggage.

"No, no, I'll do it myself!" Sure enough, Xiao Ning still turned towards him.

Yu Xingwei happily put all the luggage in Ning Wei's office according to Ning Wei's instructions, and heard Ning Wei ask behind him: "Brother Yu, are you tired from the journey? Do you want to take a rest first?"

"I'm not tired. I slept well last night. I can start researching my doctoral topic now!" Yu Xingwei said enthusiastically, and then walked out of the office to stand together with Ning Wei and Lu Dongyi again.

"It's fine if you're not tired. Don't worry about choosing a doctoral topic. I'll send you [-] WeChat transfers. You can go shopping in the mall first." Ning Wei said.

"Huh? Isn't it? Mr. Xiao Ning, I brought all my clothes and so on, so I'm sorry to cost you! And this time the boss said that I'm on a business trip, and all the expenses will be reported by the laboratory." " Yu Xingwei said shyly.

Lu Dongyi was too lazy to listen. No wonder Ning Wei likes to take this guy with him everywhere he goes. He is also a stubborn and honest person, so he shook his head and focused on carrying the electric piano. The room has been vacated. Put the electric piano in.

"Brother Yu, have you thought too much? Here's the thing. Professor Lu and I made an important discovery. When someone plays the piano next to us for an hour every day to help us relax our brains, our work efficiency can increase by 80.00% or even more. A lot, so we specially invited a pianist here. Isn’t this going to prepare work clothes for her? Please go and buy it, two sets for spring, summer, autumn and winter. In fact, that kind of professional attire is not necessary. Anyway, what kind of clothes do you think? It looks good, just buy it and it’s over, if you don’t have enough money, come back and report to me.” Ning Wei explained.

Hearing this, Yu Xingwei was stunned: "Is there such a thing? Mr. Xiao Ning, you should have said it earlier. I have passed the eighth grade of classical piano in Xijiang Province. Although it is an amateur test, my level is still acceptable."

Ning Wei blinked and looked back at Lu Dongyi.

"Just let him try the piano?" Lu Dongyi suggested.

"Then you go play one?" Ning Wei pointed to the electric piano that had been moved into the classroom.

"Okay!" Yu Xingwei rushed into the classroom excitedly, first looked at the electric piano and shook his head, and said, "I used to play the piano, but this is really the first time I've played the electric piano."

"There's so much nonsense." Ning Wei couldn't help but say.

"Hey, then I'll make a fool of myself."

Yu Xingwei connected the power supply, tested the sound in the position, stepped on the pedals below, searched for a sense of rhythm, and brewed a lot of emotions. Finally, his hands rested on the keyboard of the piano, and then his hands began to move lightly. Jump up on the keyboard.

The computer doctor chose Mozart's Turkish March, and the next moment the brisk piano sounded in the small classroom.The workers who had just moved the piano gathered around to appreciate Yu Xingwei's head-shaking performance.

However, 2 minutes later, Ning Wei and Lu Dongyi looked at each other, then shook their heads almost at the same time.

Ning Wei commented very pertinently: "This is the eighth level? It seems that it is really not good. It is not as good as classmate Jiang."

Lu Dongyi nodded in agreement: "Yes, I don't understand what he played, it has no effect at all."

The voices of the two were not loud, but the classroom was not too loud, so the piano sound stopped abruptly, and the moving workers dispersed by themselves when they saw that there was no excitement to watch.

Yu Xingwei thought it was an electric piano when he saw it, so he subconsciously thought that the pianist Xiao Ning and Professor Lu hired was not too good, and he was really superficial.But I still couldn't help asking the confusion in my heart: "President Xiao Ning, Professor Lu, if that teacher plays the piano very well, would he not like using electric piano? Teachers are still very particular about playing the piano."

"Don't worry about this, just go shopping for clothes." Ning Wei said.

"Mr. Ning, it's okay to buy clothes, but tell me the size? Otherwise, what if it doesn't fit?" Yu Xingwei said.

"Well, the height is about 1 to 67 meters. Tell the salesperson to buy the skinny ones at this height." Ning Wei thought for a while and said.

"Oh! Is that men's clothes or women's clothes?" Yu Xingwei asked.

"Of course it's women's clothing." Ning Wei glanced at Yu Xingwei.

"Okay, then I'll go!" Yu Xingwei spread his hands helplessly.

"Well, tomorrow we will formally study your doctoral dissertation. By the way, remember to cut off all the hang tags after buying. Anyway, there should be nothing on the clothes that reflects the price. If you have more money, you can also buy two for yourself." Set up." Ning Wei finally confessed.

……

Yu Xingwei's biggest advantage is probably his super good attitude, not to mention spending money on public expenses. Although many straight men would feel embarrassed about buying women's clothing, Yu Xingwei actually feels pretty good. After all, the girls at the counter When facing the God of Wealth, there will be no discriminatory gazes at all, and he will only warm a single man with the warmest words.

"Hey, who has a boyfriend like you is so considerate, your girlfriend must be so happy to receive your gift."

In fact, in the face of the beautiful lady at the counter, Yu Xingwei really wanted to say that I am still single, but thinking that he doesn’t seem to have the capital to spend [-] to buy clothes casually in the metropolis of the capital, is it still worth it? I held back the words.

After returning, Yu Xingwei handed over the things to Ning Wei, and Ning Wei directly handed them over to Lu Dongyi, and asked Professor Lu to hand them over to Jiang in the name of the research center.Based on Ning's understanding of classmate Jiang, after Meng Lang's confession that day, if he gave it away, the other party would most likely not want it.

Even when classmate Jiang came by appointment at night, Ning Wei just sat quietly in the office and listened to the sound of the piano from the small classroom next to him, without going over to take a look.

Yu Xingwei was probably the one who hurt the most.

When classmate Jiang played, Yu Xingwei could only quietly accompany Ning Wei and listen quietly in the office, but after all, he is an eighth-level piano amateur player, and his appreciation ability is naturally not what Ning Wei and Lu Dongyi who know nothing about piano can do. In comparison, if you ask him to give a comment, the piano level is quite satisfactory at best. If you give him the score, he can play it. What the hell are the two great people so intoxicated?

Of course, he didn't dare to say such things, and he didn't dare to ask, but after the initial period of discomfort, Yu Xingwei discovered that the teacher opposite him actually played well.This mentality can probably be written into a paper, "On the Influence of Big Brothers".

The sound of the piano finally stopped, and after the sound of the piano cover being closed, Lu Dongyi passed by.Although the clothes are placed over there in the piano room, he has to hand them over to make it more formal.

Lu Dongyi didn't say anything about Ning Wei's decision not to meet Jiang in the past. Anyway, he doesn't understand the love between men and women, and he doesn't intend to get involved. He just needs to do his own thing well, such as Watching Jiang Chenshuang take away the "work clothes", then returned to the office and nodded to Ning Wei.

Seeing Xiao Ning's relieved expression, Yu Xingwei probably understood what was going on, and then suddenly felt that the piano sound just now seemed to be more pleasing to the ear.Of course, he would rather not talk about this kind of thing, and he would never ask.

only……

"Oh, I haven't booked a room yet, where will I stay tonight?" Yu Xingwei slapped his forehead and asked.

"What room to book? Go live with me." Ning Wei glanced at Yu Xingwei and said.

"This is so embarrassing, won't it be too disturbing?" Yu Xingwei was not too surprised when Lining Wei told him about buying a house on WeChat before.

"Well, it's fine if you're moving out when it might disturb me." Ning Wei thought for a while and said.

Yu Xingwei: "..."

……

Just these two days passed by, as if feeling that he had owed a "huge debt", student Jiang came to the research center for two consecutive nights to play for a full hour, and then left quietly.

The next night, Ning Wei stood in front of the window and took a peek. Classmate Jiang changed into a green skirt bought by Yu Xingwei, which perfectly outlined her slender figure. The only pity was that she could only see her back. After watching the girl go away, he patted his head again.

Ma Dan... forgot to ask Yu Xingwei to buy a few pairs of shoes by the way.

I couldn't help it, so I asked Lu Dongyi to take the spare key and went to the piano room to take a look. It was really cleaned. On the table next to the electric piano, there was an extra artistic vase made of a Coke bottle. Two roses were inserted, which seemed to add a faint fragrance to the piano room.

"Well, Mr. Xiao Ning, I think if you really meet someone you like, you should be brave." Yu Xingwei finally couldn't hold back and said something subtle.

Hearing this, Ning Wei felt a little depressed.Why are you doing this now?Isn't he too brave?

"Brother Yu, do you understand my thesis? Still have time to take care of my business?"

"Ahem, I understand, let's continue to study. But it's almost 11 o'clock..."

"Forget it, go back."

……

No matter how depressed you are, you have to do serious things.

Fortunately, as long as Jiang Chenshuang could come and play the piano for an hour every night, it would be enough for Ning Wei to relieve her inner discomfort and at least concentrate on doing her own things.On the third day, Ning Wei went to the computing center again. This time, instead of looking for Teacher Liu, he found an empty seat and logged in with his account and password.

The calculation is correct, the calculation process and calculation results have come out, which is consistent with the expectation, which also means that he can submit a paper.

After returning to the research center, he imported the calculation process and results copied from the computing center into the paper, and then submitted it according to the email address published on the official website of the conference. Of course, he did not forget to add what Mr. Liu mentioned, "This research work is supported by the school-level public platform of Peking University's high-performance computing." After all, once the paper is accepted by the conference, it can be exchanged for 3 hours of free time. Please trouble Tian Dao.

After clicking the send button in the mailbox, for Ningwei, the recent research and development work has come to an end, and the next most important task is...

Ning Wei glanced at Yu Xingwei who was still working on his thesis, and suddenly felt that his life was very hard. For example, he had taken on a heavy responsibility that he shouldn't have taken on at his age.

When Liu Cong was looking forward to schoolgirls every day in the dormitory group on WeChat, he had to take on a problem that only a serious doctoral supervisor would need to consider-how to train a qualified doctoral student, and let him have the ability to complete independently Capabilities of the subject...

"Brother Yu..."

"Ok?"

"I look at you and suddenly feel very tired..."

"This..." Yu Xingwei pondered for a moment, and then said seriously: "President Xiao Ning, why don't I help you take that classmate Jiang to your house tonight? Then I'll go to the hotel."

Lu Dongyi raised his head, glanced at Yu Xingwei, and commented seriously with a sad face: "Xiao Yu, your achievements in the future must be limitless!"

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

155 That Chinese undergraduate student who once ruled our fear is coming again?

Yu Xingwei felt that Yanbei University was a weirdo.

For example, Lu Dongyi.

My own arrival directly took up another piece of the office, which is not too big, but Lu Dongyi didn't show any displeasure...

Another example is that he couldn't understand why Ning Wei's achievements couldn't handle classmate Jiang.

But one afternoon, after Yu Xingwei ran into classmate Jiang in the cafeteria, he found that she was still wearing his extremely plain clothes, and that night when he played the piano for two people in the office wearing the "tooling" he had bought, Yu Xing Wei felt that he finally understood something, but he didn't fully understand it.

That's why he had the words of his instant response.

This feeling is very mysterious.

Just like those algorithm bosses who have received Ningwei's manuscript, their feelings are also very mysterious.

……

Like SODA, STOC is the top international conference in the field of theoretical computer science, but it is organized and supported by the ACM Algorithms and Computational Theory Interest Group.

But in fact, if you study carefully, you will find that although the two conferences are supported by different organizations, in fact, the vice chairmen and members of the various program committees of these conferences all have the same name, and it is natural to review countless submissions. Most of them are the same group of people.

This is the influence of international academic leaders.

When someone has achieved great success in a certain field that is recognized worldwide, the credibility of the conference seems to be a little bit lower if the various top conferences in this field do not give you a name.

So many people who saw Ningwei's papers were acquaintances he had met at the SODA conference.

Such as Professor Shen, such as Professor John Wilson, and so on.

Of course, there are many that Ningwei has not had time to know. After all, the biggest difference between STOC and SODA is probably that STOC is more inclined to theory than specific application. This is also the reason why Ningwei decided to submit his manuscript to the conference.

80.00% of his papers are pure theoretical dry goods.

……

Massachusetts, referred to as Massachusetts, has a temperate climate with four distinct seasons and a short summer.

The same is true of Cambridge, where Harvard University is located, but August is still hot and dry, and the air conditioner in John Wilson's office has been turned on for three consecutive days. In fact, he spends most of these days in the office, even sleeping. .

This situation is rare.

But there was no way, when Ningwei's 207-page paper was conveyed layer by layer by countless invited reviewers of the conference, he finally received the email, and then began to study the paper without sleep.

Whether it is mathematics or computers, the number of people doing pure theoretical research is the least.

Because doing purely theoretical research is actually very boring and tedious, and the threshold is extremely high. If it is not because of strong interest and strong intelligence to support it, it will be difficult to persist.Not to mention that from a purely material perspective, theoretical research is often laborious but thankless.

After all, what theoretical research puts forward is a guiding ideology, which often affects the future that is not known for a long time.Especially once the theory is specific to the application level, it involves various promotional cost considerations and interest disputes, so it is not that the theory developed is extremely advanced, and it will definitely be accepted by the real world.

But it is good to do theoretical research, because if you really make subversive results, you will immediately become the most shining star in the academic world, and fame and interests will come one after another. Even in the distant future, these theories will be If it is applied to reality by scientists, then all these application-level achievements in the future will not be able to get around the name of this theoretical breakthrough.

Such as Newton, such as Einstein, such as Boltzmann...

Especially Boltzmann, although because the theory he proposed was not understood by the world at the time, he finally chose to end his life by suicide, but all scientists who study thermodynamics and statistical physics can't get around this name.

These are the two ways to be a theorist. Either you will be famous forever, and the theorems, formulas, and conjectures named after it will affect the world forever, or you will remain unknown for a lifetime. After a hundred years, you will probably disappear into the long river of history like ordinary people. Among them, no one remembers.

Obviously, the number of the former is extremely rare. There are only a few hundred theoretical pioneers who can always be remembered in the thousands of years of human civilization history.And most of them only leave names in specific academic circles.

For example, the famous British scientist Dalton, except for students majoring in physicochemical biology, few people still remember that he is the father of scientific atomic theory recognized by the academic circle.

At this time, the reason why John Wilson was so obsessed with soaking in his office was because he discovered that a new star who was likely to be remembered by future generations was rising.

The success of the turbulence algorithm has given Ning Wei a place in the field of computer algorithms, but in John Wilson's view, the turbulence algorithm is nothing compared to this paper, even though this algorithm has been proven to bring great benefits. The economic benefits, and when this paper will bring economic benefits is still unknown.

The reason is very simple. In John Wilson’s view, there is actually a standard for evaluating the scientific contribution of the world’s scientific theorists’ lifetime research results. This standard has nothing to do with immediate economic benefits, and it’s for those who engage in applications. Care about things!

For theorists, the criteria for judging their contribution should always be at the top of the list is the foundational contribution, which is what Ning Wei said.

Because once a pioneering theory is accepted by the industry, there will be hundreds of scientists working on the basis of this theory, and all these achievements are based on the theory proposed by the founder.

From Ning Wei's thesis, he sees the potential of laying the foundation for a detailed branch of computer theory. Even if one day these theoretical achievements start to be applied in reality, Ning Wei will also become the most important computer theory of this century. Scholars, at most one can be added at the end.

What's even more frightening is that Ning Wei is only 22 years old this year, and he is far from reaching the peak of a respected computer theorist's achievements. With the help of scientists, he enriched his theory.

Let all theorists who study big data have a new and more intuitive understanding of big data.

For John Wilson, who also studies computer theory, the shock that Ning Wei's paper brought him can be imagined.

The only fly in the ointment is that in this 207-year paper, 192 pages are devoted to discussions and explanations in the field of pure numbers, only 8 pages are for various standardization suggestions at the computer application level, and 7 pages are for supercomputing. issued verification report.

In other words, excluding the last 15 pages, this is a pure number paper that should be submitted to the top four major mathematics journals.But thinking of Ning Wei's current relationship with a group of people in the mathematics community, John Wilson subconsciously smiled knowingly.

After all, in his opinion, it would be a waste of money if this paper was submitted to Nature.

These days, he has sent Ning Wei's paper to several close friends, many of whom are experts in the field of pure numbers, and have had in-depth exchanges with other reviewers of this paper. convergent.

It was enough to make him tremble with excitement.

The only thing that makes him dissatisfied with this paper is probably the unit above it, Yanbei International Mathematical Research Center...

He regretted why he didn't have a deep talk with Ning Wei at the SODA conference. He should have paid more attention to this young man and invited him to Harvard to study... No, he should be hired as a professor, God, God only knows What an opportunity he had missed!
