Hammer of Technology

A physicist is like a passenger who knows his destination but does not know which car to take to get there; a mathematician is like a driver who has a car but does not know where he is going.

Well, now he feels like that driver, who doesn't know where to go.

I happened to run into a professor who came to work in the hospital, and greeted him, "Hey, Professor Lu, where are you going?"

Lu Dongyi shook his head blankly, and replied: "I don't know, I just walk around casually, I think this yard can't accommodate me anymore, I have to take my time."

"Can't tolerate you anymore? Who can't tolerate you anymore?" The professor was a little puzzled, after all, Lu Dongyi seemed to be in a very bad state.

"Ningwei's large number migration theory made me a little dizzy. Although I think it is still difficult to put it into practice, because it requires the entire industry chain to reset the standard for his theory, such as storm, Streaming big data computing platforms including hadoop and spark have to be eliminated, but if his theory can be completed as in his ideal state, big data platforms all over the world in the future may be based on his theory and re-developed. Construct."

After almost subconsciously expressing his thoughts on the questions in his mind just now, Lu Dongyi raised his leg and brushed past the professor, leaving the professor standing there in a daze.

……

There is a saying, why does every university have a school of mathematics?Because it can save the country a lot of expenses in treating mental patients in hospitals.Lu Dongyi's state at this time is probably to prove how correct this statement is.

When a person falls into a state of confusion, he often really doesn't know what he is doing, and everything is a subconscious reaction.

It's like a very famous literary image, Mrs. Xianglin, in the handed down works of a master writer in modern China who likes to talk nonsense about everything; Lu Dongyi at this time is very similar to the tragic image in this literary work.

God knows how many people he met while wandering around in the yard, and how many times he subconsciously repeated what he said just now. Anyway, at least half of the people in the yard were taken a little dizzy at this time.

However, Lu Dongyi was not alone in this state.

In Jiangcheng University, there is another doctor who is in a similar state to Lu Dongyi at this time.

That's right, it was Yu Xingwei.

After hanging up Ning Wei's phone call, Lu Changbin called Yu Xingwei to the office, and said straight to the point: "Xiao Yu, pack up, and book a ticket to go to the capital in these two days to find Ning Wei."

"Huh? What are you going to do with President Xiao Ning?" Yu Xingwei asked confusedly.

"Ning Wei hasn't communicated with you before?" Lu Changbin looked at his disciple with an extremely complicated expression and asked.

Yu Xingwei looked blank, and replied: "No. I'm not afraid that Mr. Xiao Ning must be very busy when he just went to Yanbei University, so I haven't talked to him much. Sometimes I have questions to ask him, and he has several questions. I only came back when I was young, so I will try to disturb him as little as possible. I haven't talked about anything in the past few days."

"Oh!"

Lu Changbin nodded, and then said: "Just now I called Ning Wei, he has researched a new theory, I hope you can use his theory to select a doctoral topic, and then cooperate with him to do some specific work, and help you fight for it. The eligibility to go to the STOC conference to give a report in September. He didn’t tell you to go so early, maybe he was planning to communicate with you remotely, complete some work, and help you to graduate within half a year.”

"However, I think that since Ning Wei is willing to give you this opportunity, don't miss it. Although the Internet is advanced now, face-to-face communication is definitely much more efficient than remote communication. So you might as well just go there and figure things out Come back again. Or you can just stay in the capital and help out, anyway, you can write your doctoral dissertation wherever you go. Don’t be afraid to spend money, keep the receipt, and you will be reimbursed when you come back to the laboratory.”

Yu Xingwei nodded blankly, the amount of information was a bit large, and he hadn't been able to fully digest it yet.

Looking at his disciple's dumbfounded look, Lu Changbin couldn't help but confessed: "Yu Xingwei, you must seize this opportunity. I probably heard Ning Wei describe his project. If you can really follow Ning Wei , If you do a good job in the project, even if you win the Turing Award in the future, it is not impossible. But if you fail to seize the opportunity, you will only be an unsupportable idiot for the rest of your life. Remember, luck is very It's important, but if you have luck and don't work hard to seize it, it's better to never have that luck. Do you understand?"

Yu Xingwei nodded quickly, and replied: "Understood! Thank you boss, I will book the ticket today, then I will go back to pack my things and leave early tomorrow morning."

"Okay, you go, remember to find someone to explain the matter at hand." Lu Changbin waved Yu Xingwei away, watched his lover walk to the door, and reminded: "By the way, remember to take the passport or something Bring them all, if the invitation letter from the Stoc Conference is really issued, you can apply for a visa directly in the capital. If you need any information here, call me, and I will fax it to you!"

"Okay, boss!"

……

In this way, Yu Xingwei who walked out of Lu Changbin's office also fell into Lu Dongyi's state.

The only difference is that he was not shocked academically, or was so severely hit that he doubted his academic level. It was simply because the good news came too much and too fast at once, causing his brain to start There is a downtime.

And he didn't wander around, but just returned to the laboratory downstairs in a daze, sat in front of his workstation, and stared at the display screen in front of him in a daze.

The doctor brother next to him couldn't stand it any longer. Isn't it too fair to touch fish?

Recently, the laboratory projects are rushed, everyone is busy, you f**king went to the boss and pretended to be dead when you came back, how could everyone feel happy?

"I said Yu Xingwei, what are you thinking? Hurry up and work! Everyone has to work overtime if we can't finish today! Arsenal will play against Blackpool tonight, but we have all made an appointment to go to the bar to watch the game of!"

"Ah? Work? What do I do?" Yu Xingwei asked blankly, looking at the angry little friend beside him, his eyes couldn't even see the focal length.

"Are you stupid or just pretending to be stupid? You asked me what I did for the request that I just sent out today? What were you doing just now?" The little friend was angry.

"Oh, just now, just now, the boss told me to go to the capital to meet Mr. Xiao Ning. Because Mr. Ning has studied a new set of theories, he hopes that I can use his theories to determine the topic of the doctorate and finish it as soon as possible, so let me go over there and talk to Mr. Ning. Talking with President Ning. By the way, President Xiao Ning will take me to give a report at the stoc conference. The boss suggested that I work closely with President Ning and try to graduate with a Ph.D. in half a year."

"What should I do? If I can't graduate with a Ph.D. in half a year, and I can't work with Mr. Ning on projects in the capital, and let down the love of the boss and Mr. Ning, what should I do? The boss said that I will be mixed with Mr. Ning." Come on, maybe you can win the Turing Award in the future." Yu Xingwei said dreamily.

In fact, Yu Xingwei's voice is not very loud, but the closed environment of the laboratory does not need to be loud enough for everyone to hear what he is saying, so the next moment, the originally quite rhythmic "papapa..." The sound of typing on the keyboard gradually disappeared, replaced by the eyes of Yu Xingwei who shot at Yu Xingwei like sharp swords.

Really, if eyes could kill, Yu Xingwei would have been killed for at least 10 minutes at this time. After all, this guy has a criminal record, and no one believed that he was just unconsciously talking in his sleep at this time.

After a long while, the little friend beside Yu Xingwei finally came to his senses: "Old Yu, what did you say just now? Do you dare to say it again?"

"Ah? Say it again?" The resentful voice finally cleared Yu Xingwei's mind, and then he suddenly found himself the focus of the eyes of a dozen people in the laboratory.

"Give a report at the STOC conference? Graduate with a Ph.D. in half a year? Get the Turing Award?" Another friend joined the ranks of condemnation, and the two sentences were gnashing their teeth.

Yu Xingwei, who was slightly sober, started his performance with the instinct he had cultivated in a year: "Huh? How do you know this? Oh, by the way, I have to book a ticket quickly, and book a ticket to go to the capital to meet Xiaoning Total pooled tickets."

"Don't stare at me like this. In fact, I don't want to do this either. You should know me well. How could I be willing to leave my friends who have struggled together? It's just that I can't refuse the arrangement of the bosses, but you guys Don't worry about me, I will report to everyone in the group when I arrive in the capital and report the itinerary. By the way, I can't go to the ball game tonight. You know, I have to pack my luggage. The time to go this time may be very short Long, I have to bring a lot of things..."

There was a moment of silence in the lab...

Then I don't know who asked: "Should I fight?"

"beat!"

"Drag out, strip the pig!"

"Hey...don't make trouble...are you serious? Help..."

……

Yanbei University.

"Hello, Professor Lu."

The timid cry made Lu Dongyi's chaotic brain gradually clear up, and then he saw the girl who looked a little cramped in front of him.

Although he was far away that night and didn't see the girl's face clearly, according to Ning Wei's description, he knew that the girl in front of him was Jiang Chenshuang, a non-professional pianist whom he had been in love with for a year.

Lu Dongyi's eyes subconsciously fell on the girl's hand. It was obvious that the girl was a little nervous, her hands were twisted together, and her fingers were still red and swollen that would not fade away in the future.

This made him subconsciously respond with a gentle tone: "Oh, you are classmate Jiang, right? What's the matter?"

"The counselor called me and asked me to come here and find Professor Tian at this time, but I don't know where Professor Tian's office is?" Jiang Chenshuang asked timidly.

The voice is not loud, slightly soft and waxy, but very clear. The Mandarin is not standard, but it is enough to communicate. When speaking, the eyes always glance down unconsciously. nervous.

For a moment, a lot of things flashed in Lu Dongyi's mind. As for the girl's appearance, he didn't pay much attention to it. He just thought that when the girl lowered her head, she could see the long eyelashes and trembling slightly, which looked very comfortable.

"Oh, that's it, it's okay, I'll take you there!" Lu Dongyi said.

"No, don't bother, just tell me which building it is, I can find it myself." Jiang Chenshuang said hastily.

"It's okay. In fact, it was really thanks to your piano sound last time. It gave me inspiration and let me solve a very difficult problem. I have never found a chance. Thank you. This time I will be evened if I lead you the way." .And I happen to have some things that I want to tell Director Tian."

Lu Dongyi said something, and then began to lead the way on his own.

"Thank you, Professor Lu." The girl followed Lu Dongyi carefully, just half a body behind.

The two walked silently like this, there was no way, Lu Dongyi was not the kind of person who could talk too much.

It was too embarrassing to walk together in silence like this all the time, Lu Dongyi suddenly thought that he could say something nice to Ning Wei, and said, "By the way, it was our little brother who was rude that night, but he has no bad intentions, pure and simple. It was because I told him that I heard you play the piano before, and he was inspired, so he wanted to help me thank the pianist in person. When we decided to go and have a look, we didn't even know if you were male or female."

"Oh!" The girl behind him replied cautiously.

Lu Dongyi sighed in his heart, it was even less than his words.

"Hey... I really didn't say that on purpose to appease you. I still remember that night you played the piano adaptation over and over again. You must be happy, but you were not proficient in playing it at that time, and there seemed to be some problems with your sense of rhythm. .Because of that time... I, um, I took my junior brother to listen to you playing the piano for a long time!"

"Oh, yes, I think he can really change the world!"

"Ok?"

151 On Pretentious Rhythm

"Professor Lu, hello! Professor Lu, is this the new junior sister in the academy?"

There are a total of seven buildings in the research center, but the yard is actually quite large.When Lu Dongyi brought Jiang Chenlu to Building No. 7, it coincided with the end of the postgraduate intensive class. They filed down from the second floor and greeted Lu Dongyi one after another.

Lu Dongyi also gave them lessons, so he naturally knew each other, but this time when a group of people greeted each other, they all focused on the girl behind him.

However, there are currently no girls in the intensive research class of the School of Mathematics, but a bunch of energetic young men. It's not easy for him to say that this is the girl that the younger brother likes, so don't make any wrong ideas.Afraid of irritating these young guys, mainly falling into Jiang Chenlu's ears, what does this girl think?

Lu Dongyi sighed in his heart, turned his head to look at Jiang Chenlu, and sure enough, his head was lowered, and his two fingers were tightly clasped together...

"Ahem, well, today is Professor Jules from the University of Maryland who will tell you about the zeta function of shimura clusters? Let me tell you, this question is very important, especially when Professor Langlands and Professor Kettwitz proposed The idea of ​​comparing point counts with trace formulas, the part that finally connects the zeta function with the automorphic l function, and some recent developments in Abelian shimura clusters that will be mentioned at the end."

"Hurry up and go back to study carefully, look for relevant materials, and sort out any questions immediately. You can ask Jules or other professors carefully in your spare time. Go back and focus on the short-term courses of this special training period. The center will organize a very serious exam, and the results will be sent to your tutors, so you don’t need to worry about other questions, and go check the information quickly!”

Those two sentences extinguished a group of graduate students' insistence on appreciating beauties.

Although it seems that I have never heard of the precedent of signing up for classes, the research center also organizes exams.But Lu Dongyi is a professor after all, and the meaning of the warning in these words is very obvious, it is the best policy to flash talent.

After all, although there is no precedent, they have nothing to do if they insist on playing like this. A group of people dispersed, and many people secretly looked back at Jiang Chenlu, and then began to gossip: "Hey, you said that girl Is it Professor Lu's girlfriend?"

"Which doctor's girlfriend I still believe, let's forget about Professor Lu. I will tell you that among all the professors who are single because of their strength, I will give in to Professor Lu. You don't know yet, do you? The German female professor said last time It is necessary to invite Professor Lu to dinner, and then Professor Lu will take her to the cafeteria to buy four steamed buns and come back to continue discussing issues in the office."

"Really, is there such a thing?"

"What are you doing lying to you? My tutor told me that many professors know about this, okay?"

"Professor Lu is sincere, in the face of sexual temptation, he will not forget the buns! Awesome!"

……

"Don't mind, these are all short-term course training for graduate students from the School of Mathematics, and they have no bad intentions." Lu Dongyi explained.

"Oh, I know, thank you, Professor Lu." The girl responded softly behind her.

"Why are you thanking me? I'm helping them avoid a little trouble, hey...after all, the younger brother is in a bad mood, and he always has a way to make everyone feel as bad as him. It's gone." Lu Dongyi sighed.

Jiang Chenlu asked softly, "Huh? Professor Lu, can you tell me, Professor Tian called me here, what exactly do you want to talk to me about?"

Lu Dongyi paused, then pointed to a building in front of him: "It's almost there, I'll let you know when I take you up there."

……

In Tian Yanzhen's office, Ning Weizheng sat on the side obediently.

After explaining his thoughts to Lu Dongyi, his brother Lu went out to relax for about half an hour, and he was called by Director Tian.After entering the door, I had a face-to-face meeting with a professor whom I met for the first time. After the professor looked him up and down curiously, he left without stopping, and then he began to accept questions from Director Tian.

"Lu Dongyi said that you successfully constructed a mathematical theory of big data migration?" Tian Yanzhen asked directly.

"Well, yes!" Ning Wei nodded quietly.

"Have you verified it together?" Tian Yanzhen asked.

"It can't be said that it has been completely verified. You know, the theory has not been passed on to specific results, so it is just a theory after all. I am also preparing to apply for the use of supercomputing in the computing center to verify some related issues. If the verification process can meet the As expected, it is probably about the same." Ning Weihao replied leisurely.

Tian Yanzhen didn't show it, but the shock in his heart was no less than that of Lu Dongyi.

He hasn't seen Ning Wei's research results yet, but the professor who expressed his farewell to Lu Dongyi just described it to him in detail. He knows that with Lu Dongyi's ability to distinguish, if Ning Wei's research is only a general result, He definitely wouldn't let his proud disciple lose his composure like that, and even say such bastard words as "this yard can no longer accommodate me".

After all, Lu Dongyi is also considered a man who lives his life like Versailles!

"How about this, you go directly to the computing center tomorrow to find Mr. Liu, just say that I let you go, and then just do the verification directly. I will talk to there in advance. If there is no problem after the verification, you can come to me first Make a report, if there is no problem, the research center will hold a report meeting for you, and some experts from home and abroad will be invited to listen and verify." Tian Yanzhen said.

"This...Director Tian, ​​I plan to try to submit a paper for the STOC conference after verifying it." Ning Wei replied a little embarrassed.

According to Tian Yanzhen, the time will definitely overlap.

Ning Wei did a special investigation this time. This year's stoc conference will be held in the middle of next month, and the official website has opened the paper delivery window.If he wants to make a report at the center first, he is afraid that there will be some problems in time.

"Stoc conference? Isn't your paper in the direction of mathematical theory? Submit to the computer conference?" Tian Yanzhen didn't react for a while.

"If there is no problem in the verification, I will give some solutions in the paper to achieve fast and safe big data migration through my theory. I think it should not be a big problem." Ning Wei explained.

Tian Yanzhen patted his forehead, and almost forgot that the kid in front of him is not a pure mathematician. In fact, the experience of deriving from the ns equation and developing the turbulence algorithm has already shown that Ningwei can advance from mathematical theory to specific algorithm. Ability, he does not have this ability.

This is probably why this little guy doesn't think about developing in the direction of pure mathematics.

A successful mathematician does not necessarily become a successful computer scientist, but those computer scientists who are successful have a deeper understanding of related mathematics than ordinary mathematicians.

"Well, if the conference approves your paper and invites you to give a report, the research center can wait for you to come back from the conference before holding it. Or if your results have been reviewed, the research center can Open a course just for your theory." Tian Yanzhen said after pondering for a moment.

"This time..."

Before Ning Wei could finish his sentence, there was a knock on the door, interrupting his words.

Tian Yanzhen glanced at the time, a smile appeared on his face, and said, "Please come in!"

Ning Wei looked at the door of the office, and immediately saw Brother Lu who had just disappeared. Before he could look back, a familiar girl lowered her head slightly and followed Lu Dongyi into Tian Yanzhen office.

Ning Wei was stunned for a moment, wondering if Director Tian was so simple and rude, and then subconsciously stood up.
