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

Chapter 104, being your classmate is very stressful. Submitting to the United States to earn foreign exchange? High-speed array processor project is coming soon.

After dinner, Wang Duoyu returned to dormitory 303. Zhu Hanting and the other seven people all looked at him with resentful eyes.

"Student Wang Duoyu, you're being dishonest! Didn't you say last time that you'd explained everything clearly? Why haven't you said a word when you've published so many papers in Science China Mathematics?"

Yu Xinyao was the first to condemn, followed by Tian Maohua, Zhu Hanting and others, and then Wang Duoyu fell into complaints.

The enemy has seven mouths. How could Wang Duoyu possibly defeat them in such a battle?
What's more, he is not in the right, so he might as well just admit it.

"Okay, okay, this is my mistake. I forgot. So didn't I bring back so many pastries for you yesterday? You've eaten them all, right?"

Wang Duoyu turned the tables, and Mo Ruogao and the others were dumbfounded: Damn it, isn’t that the travel souvenir you brought back?
However, they are grateful for what they have received, and even if they are right, they can't say much at this moment.

Yuan Jigang was still a little unhappy and muttered:

"Duoyu, be a human being. Do you know how many papers you've published in Science China Mathematics? Damn, ten as far as we know, and two more in Acta Mathematica Sinica."

"If you are so outstanding, it would be very stressful for us to be your classmates."

Everyone else in the dormitory fell silent, especially Zhu Hanting.

Before the National Day, he was still thinking about competing with Wang Duoyu and shining silently, but he never expected that the other party would be far ahead of him.

If the two of them were competing on Akina Mountain, Wang Duoyu would have already reached the top, but he would still be starting his car at the foot of the mountain, moving slowly forward. Not to mention seeing the opponent's taillights, it would even be a question whether he could smell the opponent's exhaust gas.

Is this the gap between ordinary people and geniuses?
It's suffocating!
"Duoyu, you shouldn't have any other identity, right? Are you hiding something from us?"

After a moment of silence, Lou Jianguo suddenly asked in a low voice.

Coming from a rural area in Sichuan, he was originally very confident. After all, he was the first college student in their Wolong Village.

But on the day of reporting, he felt the disparity of the world. Then came the entrance examination, and then the many other identities of Wang Duoyu, the top scorer in the college entrance examination.

Gradually, Lou Jianguo became less confident, and even felt a little inferior when facing Wang Duoyu.

why?
Because he was still in the basic class, Wang Duoyu didn't need to go to professional classes. He went to the library to read books every day. The books he read were professional journals and mathematics books that Director Wu and others had asked someone to buy from abroad.

It can almost be said that they are still studying in ordinary first-class universities in China, while Wang Duoyu can already choose foreign works independently.

If Lou Jianguo were asked to look through those journals, the language barrier alone would be enough to discourage him.

Tian Maohua and the others immediately turned their gazes towards Wang Duoyu. Upon hearing this, Wang Duoyu's eyes turned slightly and he said:
"You know what? Today I have a new identity. I won't pretend anymore. I'm going to be honest. I'm a wealthy man, haha."

Everyone was shocked and thought Wang Duoyu was joking, but soon they were really shocked.

Because Wang Duoyu said it so seriously, it seemed like it was true.

"Well, I've been in the library reading books and writing papers all the time."

Wang Duoyu told her that he and Tang Fengzhen had consulted him, and then he was recommended to an experimental project in the Department of Physics and received a monthly subsidy of 60 yuan.

The seven people in the dormitory suddenly lost their composure.

Yuan Jigang hugged Wang Duoyu all of a sudden:

"Damn it, you're so awesome, aren't you? Let me calculate your current income: 62 yuan as an intern researcher, over 30 yuan in literary royalties, over 20 yuan in university student subsidies, and 60 yuan in project subsidies."

"By the way, you also have the paper manuscript fee. How much is this?"

To be honest, the royalties for papers are really low. Each math paper written by Wang Duoyu earns about three to six or seven yuan, which means an average income of about fifty yuan.

Hearing Wang Duoyu's Versailles words, Zhu Hanting, Tian Maohua and others twitched their lips: Are mathematical papers calculated based on royalties?

If Wang Duoyu had not submitted so many papers to "Science China·Mathematics", would he have been able to become an intern researcher at the Institute of Mathematics of the Chinese Academy of Sciences?

Chunchun, you are dreaming!

But even with this calculation, Wang Duoyu's monthly income has exceeded 170 yuan.

Damn, many first and second level professors’ salaries are around this level, right?
"I have to treat you. Damn it, living in the same dorm with you is really stressful."

Yuan Jigang and the others are very upset. Only by venting like this can they barely soothe the depression in their hearts?
"Duoyu, this time, there really is no more, right?"

After the commotion, Lou Jianguo asked again.

Mo Ruogao, a middle school math teacher, added wistfully, "If I really do have another identity, I'd really like to move to another dorm. Living in 303 is like being slammed every day. It's too hard."

Seeing Wang Duoyu shaking his head, Zhu Hanting, who had been silent all this time, suddenly spoke:

"Duoyu, you're being dishonest again. Didn't you submit a math paper to the American Annals of Mathematics last time? I'm afraid you'll be earning royalties in US dollars by then, right?"

hiss! ! !
In an instant, Mo Ruogao, Yuan Jigang, Yu Xinyao, Tian Maohua and the other six people all gasped and their faces became extremely shocked.

Wow, submitting to a professional American mathematics journal? Earning royalties in US dollars?
Although the fee may not be much, once the manuscript is approved and published, it will be more prestigious.

By then, I'm afraid the whole country will pay attention to Wang Duoyu.

"No, you're overthinking it. I was just testing the waters. I might not be able to match their paper formatting, and they might not be able to read my handwriting, right?"

"Bullshit! Your handwriting is so beautiful! Even I, who have practiced calligraphy since childhood, praised it. How could a foreigner not recognize your handwriting?"

Yuan Jigang immediately retorted, and Zhu Hanting and others nodded repeatedly, agreeing with the former's words.

Everyone in the same dormitory was in the same room, and all seven of them knew Wang Duoyu's handwriting clearly. Although it was not as neat as printed, it was still very clear and easy to recognize.

It's not like some doctor's self-created font that only the doctor and the nurse can understand.

Therefore, the paper Wang Duoyu submitted to the United States has a high probability of being approved.

"Hey, that's not right. Han Ting, how did you know that Duoyu submitted an article to an American journal? Did you submit one too?"

Ever since the night of October 303th, Dormitory has fallen into an even more frantic state of internal conflict. What exactly happened?

At 4:30 in the morning, Wang Duoyu was the only one left in the dormitory. By 9:00 in the evening, when Wang Duoyu returned from the library, Zhu Hanting, Yuan Jigang, and the others were all ready for bed.

During this time, if you meet them on campus, they will definitely be walking in a hurry, or even running.

In the ice city in early October, the temperature has dropped, generally ranging from 2 degrees Celsius to 14 degrees Celsius.

People from the south like Lou Jianguo might not be able to adapt to such a temperature, but Yuan Jigang is from Beijing, so he should be able to adapt.

But even so, Yuan Jigang walked very fast when he was walking on campus.

There is only one truth, and that is that they are all in a crazy internal competition.

To be honest, Wang Duoyu didn’t know what they were rolling about. What was the point of rolling like this?

You have to combine work and rest. You can't practice in seclusion every day, as it's easy to go astray.

So after entering autumn, he would run a lap or two from time to time, or take a walk after meals, which could be considered as exercise.

In mid-October, Mrs. Zhou wrote back, not giving him a chance to refuse. She said that she had sealed up his letters from readers and would take them away when he came to the capital next time.

Wang Duoyu had no choice but to write another letter back, telling the old lady that she could just let her deal with it, or just throw it directly to the scrap yard.

In addition to Mrs. Zhou, another old lady, Xia Peisu, also wrote to us and talked about the high-speed array processor project.

An array processor is a processor that performs high-speed operations on arrays, vectors, or data obtained from point matrices in the time domain or space.

This kind of array processor has two meanings. One is from the functional point of view, that is, the main object processed is the array or array, not the scalar, that is, the array processor.

The other is from a structural perspective, that is, an array of processors with the same structure working in parallel under the control of the same control mechanism.

Since the 1960s, Xia Peisu and other older generation computer experts have added dedicated digital filtering components to existing computers, greatly improving the computer's computing speed for digital signal processing.

In fact, it was also in the mid-1960s that Cooley and Tukey proposed a fast algorithm for discrete Fourier transform abroad, which greatly reduced the number of calculations and promoted the development of digital signal processing.

By the 1970s, digital signal processing technology had become mainstream and was widely used in communication systems, audio processing, image processing and other fields.

As the mother of Chinese computers, Xia Peisu has a very keen intuition about the development of computers. She is definitely a leader in my country's current computer field and has always been at the forefront of scientific research.

At the beginning, she was worried that Wang Duoyu didn't know how to use basic tools such as Fourier transform algorithm and Z transform to describe linear discrete-time systems, and she was wondering whether she should give him more time.

Unexpectedly, Xia Peisu was shocked several times during the exchange of letters.

Wang Duoyu's familiarity with Fourier transform algorithms and other related mathematical tools far exceeded her imagination.

He even gave detailed and specific answers to several questions raised by Xia Peisu, so there was no need to worry that he lacked the relevant knowledge and delayed the development of the array processor project.

On October 22, Wang Duoyu received another letter from Professor Xia Peisu. He saw that the other party was ready to submit the project application and expected to establish the project at the end of this month or early next month. He hoped that he could come to Beijing at that time.

"Damn it! I just came back from the capital, and now I have to go to the capital again?"

Wang Duoyu wanted to refuse, but he couldn't.

Unlike the dual-axis gyroscope drift test bench prototype project, he joined the array processor project from the very beginning, and even helped to improve many of the theoretical calculation tools of this project.

Although Xia Peisu and his team had already added digital filtering components to the computer, this was not a true digital filter, not to mention that the project that Wang Duoyu and his team were now completing was a high-speed array processor, which had an even more different meaning.

Let’s put it this way, array processors can be seen in fields such as radar digital signal processing, sonar signal processing, oil exploration seismic data processing, image processing, real-time flight simulation, thermonuclear reaction simulation, astrophysical calculations, and structural analysis that have already appeared abroad.

Of course, foreign countries are not very advanced in this regard, because their digital processing technology has only just started.

In the library, Wang Duoyu folded the manuscript paper in half and took the letter to the post office outside the school to mail it during lunch.

At this time, Tang Fengzhen came over.

"Hello, junior student. This is the problem Professor Dai asked me to bring back. Professor Dai said this one will be more difficult because there is a lot of experimental data and it is needed urgently. He hopes you can complete the calculations within a week."

Tang Fengzhen frowned and said to Wang Duoyu worriedly.

She had looked at the experimental data given by Professor Dai, and it was indeed very complicated. It was difficult for her to complete the calculations. Even the other two teachers in the project team who were originally responsible for the calculations were very grateful.

At the same time, he felt a bit gloating. After all, he had indeed encountered a tough challenge this time. The data set was nearly fifty pages long. It would take an unknown amount of time to calculate just one set of data, not to mention fifty pages of data.

"Okay, I understand. Come over tomorrow afternoon."

Wang Duoyu took a quick look at it, smiled at Tang Fengzhen, and didn't take it to heart.

Use people's money to eliminate disasters for others.

Dai Wenyue took out a subsidy of 60 yuan from the project and gave it to him. Of course, he was not asking him to be a doorman, but to let him solve the problem.

"Will it really be possible tomorrow?" Tang Fengzhen asked in disbelief, eyes wide open.

"Well, you can come at the same time tomorrow afternoon." Wang Duoyu nodded, then lowered his head to read.

He spent every day fulfillingly, either reading or replying to letters from Xia Peisu and others.

Wang Duoyu had already sent out "Snow City Volume 2: Spring Equinox" in mid-to-early October. He rarely wrote other literary articles.

Unless I feel like writing a few thousand or ten thousand words, I won’t touch it again.

Tang Fengzhen returned to the Physics Department project office filled with worry. Professor Hong Yitang eagerly asked, "Xiao Tang, what did Wang Datian say after you took the data set over? Can you finish it in a week?"

"Is there any need to ask? It definitely cannot be completed." Ye Xiangdong, another teacher who also rejected Wang Duoyu, echoed with glee.

"No, my junior said that we can figure it out tomorrow." Tang Fengzhen responded angrily. Hong Yitang and Ye Xiangdong looked at her in astonishment.

"What did you say? You can figure it out tomorrow?"

Ye Xiangdong immediately burst into laughter and said:
"That's absolutely impossible. Does he think he's a god? He wants to figure it out tomorrow? Tsk, if he can figure it out within a week, I'll eat this table."
