The unparalleled talent of the country started from Harbin Institute of Technology

Chapter 108: It’s freezing cold in the ice city in November. A friend from afar wrote to me and asked if we could add more people to this project.
On the way back to Ice City, Wang Duoyu was flipping through a book in the passenger seat, looking quite relaxed.

This trip home is a perfect interpretation of the phrase "coming and going in a hurry".

His tenth brother must repent. After all, there is a saying that goes, "You can never learn something by teaching it, but you can learn it once."

Impulse is the devil!
Judging from this incident, Lao Shi has indeed become much more honest.

After this incident, the villagers also discovered that Wang Duoyu's ability was indeed extraordinary.

Wang Duoshi beat Zhang Jun so hard that he was hospitalized and all three of his legs were broken. Given Zhang Jun's gangster nature, he didn't extort money from Wang Duoshi to the point where he was left with nothing but three hundred yuan and a bottle of tiger penis wine. This was enough to prove Wang Duoshi's strength.

In rural areas, although tiger penis wine is rare, it is indeed 'not worth much'.

If three hundred yuan and tiger penis wine are put together, everyone will definitely prefer the three hundred yuan.

Because three hundred yuan can buy a lot of things, but if it is tiger penis wine, they have no channel to exchange it even if they want to.

It was rumored in the city that tiger penis wine was priceless, but those who wanted to sell tiger penis wine eventually disappeared without a trace.

Without channels and due to information asymmetry, of course no rural people would be stupid enough to take the risk.

Therefore, if rural people have tiger penis wine, they have to digest it by themselves, unless they are lucky and happen to meet a kind leader. Otherwise, tiger penis wine is really just a slightly better homemade rural wine.

In addition, Eighth Sister had beaten Old Ten so badly that his buttocks were bruised and he had to stay in bed for at least a week before he could get out of bed.

To sum up, that’s why Wang Duoyu hurried back to Ice City after lunch.

After the car arrived in Bingcheng, Wang Duoyu went to Bingcheng Fourth Hospital as agreed with Gu Yannian. After meeting the latter's son, he confirmed that the man did have problems with his genitals and urgently needed tiger penis wine for treatment.

Even though Wang Duoyu didn't understand medicine and didn't know whether tiger penis wine could be considered a medicine, he still completed the deal with the other party.

After the transaction was completed, he got in his car, took the money and drove straight to a nearby bank, where he deposited all the money.

After coming out of the bank, Wang Duoyu was completely relieved.

At this point, even if Gu Yannian was conducting a sting operation, he was no longer afraid of the other party.

"Brother Fang, I'm sorry to bother you again. Please be careful on your way back."

Downstairs of the HIT dormitory, Wang Duoyu waved goodbye to the other party with a smile.

Xiao Fang glared at him in mock anger, "What trouble are you talking about? Let's go!"

After he drove more than ten kilometers and parked the car to get out, he turned around and saw the gift on the back seat.

"Hey, when did you give this gift? This mathematician is quite polite."

Opening it, Xiao Fang grinned. Two bottles of tiger penis wine, should they be for him and his boss? This shouldn't be considered hush money. After all, neither Lin Dehong nor Xiao Fang is that kind of person.

This should be called "rain and dew are equally distributed", or it would be more appropriate to say that everyone who sees it gets a share!
In dormitory 303, at night, Yuan Jigang, Zhu Hanting and others were concerned about Wang Duoyu's sudden return home.

The latter made up an excuse to deal with it lightly and then changed the subject.

The next day, when Wang Duoyu returned to the office of the Department of Computational Mathematics to read, Wu Congyin and others showed concern and asked him about his well-being. After chatting for half an hour, he finally got back to reading.

In the blink of an eye, October has passed quietly and November has arrived.

After entering November, the temperature in the ice city dropped even more sharply.

Overnight, when the cold wind from Siberia blew over, the whole world became chilly.

Although it hasn't snowed yet, the temperature is already below zero. The river hasn't started to freeze yet, but places like the faucets are already frozen.

"This damn weather is really cold!"

At noon, after lunch, Wang Duoyu went to the post office outside the school to pick up a letter. He was so cold that his face was almost swollen.

Because even at noon, there is no sun. Today is cloudy and there is a north wind. The temperature should be around two or three degrees below zero.

it's too cold!
"You're not wearing a hat? You should cover your mouth and nose when you go out. The wind is too strong."

Yang Xiuhua, who was sitting at the desk, smiled and responded. However, Su Zhenghuai, who was standing next to her, stared at the letter in Wang Duoyu's hand and exclaimed:

"Student Wang, you have so many letters again? Aren't they all about thesis approval?"

In this office, everyone knows that Wang Duoyu is a mathematical genius and a frequent visitor to the mathematics journal "Science China·Mathematics". You can even say he is a "water army".

Wang Duoyu often jokes that the papers he writes are very watery and that he is a member of the army of watery papers, or simply the water army.

He was really making fun of himself, but Su Zhenghuai, Shao Zongjian, Yang Xiuhua and others were really impressed. After all, every one of the papers he wrote was of extremely high value.

For example, the paper "A Method for Solving the Eigenvectors of Matrices on Distributive Grids" is of great value.

Su Zhenghuai and the others didn’t quite understand, but they felt it was impressive!
Xia Peisu was very aware of the importance of this paper, because she had originally planned to develop a vector processor, but she did not have the time yet, and the array processor had not yet been developed, so of course she could not rush.

"No, these letters are from my friends." Wang Duoyu replied and began to open the letters.

Opening letters is not like opening a blind box, nor is it like opening a courier. He can still guess the general content of these letters.

Liu Xiaoli wrote three letters in a row, talking a lot, and one of the letters still had traces of dried tears on it.

She said she missed her grandma very much.

Just this point made Wang Duoyu feel very distressed and helpless.

The other party seemed to miss her grandmother, but she wrote him three letters, almost one every two days.

After she returned to Jiangcheng in September, she wrote twenty-eight letters to Wang Duoyu over the next month.

She wrote letters very frequently, so even though they were far apart, they knew each other well.

"It seems I have to find some time to go to Jiangcheng to see her." Wang Duoyu scratched his hair worriedly and had to face reality.

Zhu Ling only wrote one letter for two reasons. First, she knew that Wang Duoyu was about to come to Beijing, and her joy was reflected between the lines. Second, she herself was also very busy.

There are many courses to study at the Chinese Academy of Medical Sciences. After all, studying medicine is no joke and there is a lot of knowledge to learn.

Zhu Ling was so busy that she didn't have much time to write letters. And when Wang Duoyu came to Beijing, she had to ask for leave, so she had to prepare in advance, otherwise the teacher would scold her.

In addition to these two beauties, he also received many work letters from the two old ladies Xia Peisu and Zhou Yanru, and Su Buqing, Tao Fangqi and others also wrote to him.

So, he did not lie to Su Zhenghuai, these letters were really written to him by his friends.

November 5, 1978, Sunday, was a day off, and Wang Duoyu and his friends went to the playground to play football. The sun was shining brightly, and although the temperature outside was very low, around -3 or -4 degrees Celsius, they still sweated when they ran.

"That's a great goal!"

There are quite a few male comrades in Harbin Institute of Technology. In today's weather, many people come out to bask in the sun, and many people also play football.

All the students in dormitory 303 went out to play a competition with the dormitory next door. It was a small field, not a big field, so it was eight against eight.

The game lasted for three hours, from two to five in the afternoon, and in the end Wang Duoyu's dormitory lost the game.

It was a pity that we were not able to make a comeback at the last moment, but after all, none of us were professionals, so we just played for fun and no one took it seriously.

Back in the dormitory, everyone was still discussing the football issue. Lou Jianguo even wanted to make an appointment to play football together next Sunday, but was rejected by Wang Duoyu.

"I can't play next week. I have to go to Beijing tomorrow night. I think I'll be there for about a week, maybe even longer, so I won't be able to make it back."

After hearing his words, the dormitory instantly became quiet, and Yuan Jigang and the others looked at him in disbelief.

"Damn it, are you on a business trip again? Going to the capital to see your concubine again?"

During the Republic of China era, concubines were the master's favorites and treasures.

Although this thing is not popular nowadays, Wang Duoyu is single, and it is not a big deal if it is just a joke among family members.

"Big wife, don't be jealous. After all, you are not from Xishan," Wang Duoyu retorted with a smile, and Yuan Jigang was immediately depressed.

puff!

Yu Xinyao and the others all burst out laughing. Wang Duoyu’s counterattack was quite interesting. Big wife!!!
Snake disease!

People in Xishan like to drink vinegar, but not many people know this because people are shaped by the land and water they live in. Now is not the Internet age, and information is not that developed. People like Lou Jianguo may not know all the customs and habits of different places.

"Duoyu, seriously, you're not secretly doing some big project behind our backs again, are you? If so, can you take me with you?"

Tian Maohua suddenly spoke up, and Yu Xinyao, Rong Guangxia, Mo Ruogao and the others immediately echoed him.

For the past half month, everyone was very busy, but we finally compromised this afternoon and took advantage of the sunny weather to go outside and play football for an afternoon.

Well, now Wang Duoyu has gone to Beijing again. If it’s not for some big project, Tian Maohua and others will definitely not believe it.

As for Yuan Jigang's joke about meeting his concubine, it was even less likely that anyone would believe it.

"First of all, this project is not mine. I don't have the power to just add people."

Wang Duoyu did not hide anything, but said frankly:
"Secondly, this is a project I can't discuss in detail. However, I can tell you that this project requires you to have the most basic knowledge. That is, you must be able to use basic tools such as the Fourier transform algorithm and the Z transform to describe linear discrete-time systems."

Everyone: "."

Zhu Hanting and the other seven people all looked at Wang Duoyu blankly. They didn't know what the Fourier transform algorithm was. This thing was in mathematical works and professional journals.

But they really don't understand this advanced knowledge yet.

Fourier was a French mathematician, and they knew this, but what was the use of knowing this?
You should know that Fourier did a lot of theoretical research in the field of mathematics, such as the famous Fourier transform, which has many different variants, such as continuous Fourier transform and discrete Fourier transform.

These contents are relatively advanced, and Zhu Hanting and others have not come into contact with them yet.

Even though Zhu Hanting was a genius who almost got admitted to Tsinghua University, he did not study these advanced mathematical theories in a more systematic and in-depth manner during the years he spent working in the countryside.

"So, it's not that I don't want to take you with me, but I have no other choice."

After a pause, Wang Duoyu continued:

"Of course, if there's a chance in the future, I'll definitely call you, but you also need to have a certain foundation, so starting tomorrow, you just keep rolling up. Forget about playing football. The weather will get colder and colder, which is not suitable for playing football anymore."

Upon hearing this, Lou Jianguo and others nodded silently and seriously.

The next day came in a flash, and it was another day of opening the exam.

Zhu Hanting took the organized paper and went to the post office next to the school to mail it out again.

In late September, the manuscript he sent out was rejected by the journal, which made him sad for a long time. To be honest, he was very depressed.

But he soon recovered and continued to submit his works.

If Wang Duoyu knew that he would continue to hit a wall, he would definitely suggest that he submit his paper to journals of lower rank instead of top journals.

The requirements for papers published in top journals are very high, and Zhu Hanting does not yet have that level, so it is of course easy for his paper to be rejected.

However, this time, the time interval was only three days, that is, on the fourth day after Wang Duoyu went to the capital, he actually received a letter from the Magic City.

The letter said that the angle chosen in the paper he wrote was quite good, but the proof process was too simple and not detailed enough.

Therefore, it is impossible to determine whether the result is right or wrong, but the journal invited him to go to Beijing to revise the manuscript.

Seeing such a reply, Zhu Hanting trembled all over.

Although his manuscript was not approved, it was still a huge improvement.

You should know that his thesis was not revised by his teacher. He wrote it all by himself and got to where he is today step by step.

"I thought I would have to go through ten rejections, but I didn't expect it to be accepted on my second submission. Although there are still some flaws, I firmly believe that publication is not far away."

Zhu Hanting was greatly encouraged and immediately contacted the Journal of Mathematics, saying that he could go there to revise the manuscript.

Seeing the words "Handan Road in the Magic City", Zhu Hanting's mood became cheerful, and even the bucktoothed lady working in the post office looked much prettier.

"Acta Mathematica Sinica" is the top mathematics journal in China. Being able to publish a paper in this journal is enough to prove its value.

In dormitory 303, Lou Jianguo saw Zhu Hanting packing his luggage and asked curiously.

Yuan Jigang and the others didn't react until Zhu Hanting said casually, "Oh, I'm going to the Magic City. The Ice City is too cold. It's warmer in the Magic City. I'm going there to spend the winter."

"Are you crazy? It's called warm in the south?" Yu Xinyao and the others immediately put on expressions of concern for mentally retarded children, but Zhu Hanting retorted:

"I'm from Jinling. The Magic City is only a few hundred kilometers away from us, on the same latitude. Why isn't it warm there?"

"Damn it, it's not a festival, why are you going to Shanghai?" Yuan Jigang fired back, suddenly asking suspiciously, "Wait a minute, your paper hasn't been accepted, has it?"

As soon as these words were spoken, the entire dormitory fell silent, you could hear a pin drop, and all eyes were focused on Zhu Hanting.
