Chapter 52, Five Mathematical Papers Level Researcher
"Lao Tao, the one looking for you should be the student you've been thinking about."

In the office, Liu Taoshun handed the phone to Tao Fangqi, who excitedly took the call. After confirming that it was Wang Duoyu on the other end, he immediately said:
"Okay, okay, Comrade Wang, I'll go to your village right now. Wait for me. I'll definitely be there this afternoon. What? Don't be so impulsive. It's hard to explain over the phone. Wait for me!"

Hearing Wang Duoyu's polite refusal on the other end of the phone, Tao Fangqi frowned, then firmly stated that he would go to Dahonggou Village to talk to the other party face to face, and then hurriedly hung up the phone.

"Old Liu, you're a busy man. I won't chat with you any more. I have to go to Qingshan Township right away to meet this math genius."

"Wait a minute, Lao Tao, is the math genius you mentioned called Wang Duoyu? Did he just take the college entrance examination this month?" Lao Yuanchang stopped the other party, because if he remembered correctly, the young man he met at the Bingcheng Steel Plant yesterday was a villager from Dahonggou Village, Qingshan Township.

There are many people with the same name and surname, but there are really not many people with the same name and surname and from the same place, let alone someone who is a math genius. So there is only one truth: he and Tao Fangqi met the same person.

"Could it be?"

Tao Fangqi frowned, then suddenly realized that there were not many mathematical geniuses in the world, and it was even more unlikely that there would be someone with the same name, surname, and place. "Then, busy man, will you come with me?"

"If it were anyone else, I wouldn't really want to join in the fun, but this Comrade Xiao Wang, I really want to go and see him. Come on, wait for me a moment, I'll pack my things and be right back. Hey, Lao Liu, do you want to come with me?"

Liu Taoshun rolled his eyes. He was not going to join in the fun. It was early August and it was very hot outside during the day. It would be better to stay in the office and enjoy the coolness with the fan.

So, Tao Fangqi and Lao Yuanchang took a car to Dahonggou Village, Qingshan Township. When they arrived, it was already past three o'clock in the afternoon.

Wang Duoyu went to the brigade at about ten o'clock in the morning and made a phone call, which cost him one dollar. In fact, the brigade leader Kong Huayi did not want to take the money from him because Kong Huayi wanted to please him. After all, he was the only writer in Qingshan Township. Well, the postman Sun Shouyi was just a pseudo-writer, not a real writer.

After all, who in the brigade didn't know that Wang Duoyu often received remittance slips for his royalties from magazines? On the day the college entrance examination ended, Du Jianping, Li Dongwu, and Liang Kangmin happened to see Wang Duoyu withdrawing his royalties from the bank and depositing them into his passbook. Then, there was the uproar over the fact that he'd received 320 yuan in royalties in just two weeks.

Kong Huayi knew that Wang Duoyu was not short of money, but the more this was the case, the more he wanted to please him. It was just a dollar's worth of phone bill, and the other party didn't call every day, so there was nothing to accept.

In the end, Wang Duoyu still gave the money, and Kong Huayi had no way of refusing it, or perhaps he wanted to do this favor, but the NPC writer was not willing to accept it.

"Brother Jiu, Brother Jiu, come out quickly, there are guests coming"

At the foot of the mountain, Wang Duoyu was sitting at home, writing a paper. Then he heard loud shouting outside the door, and soon saw his sister Wang Meili, as well as Tao Fangqi and Lao Yuanchang walking into the yard surrounded by little kids like Xue Yuqing.

Wang Duoyu was quite surprised when he saw Lao Yuanchang. He stood up to welcome the two distinguished guests in. His sister took over the job of serving tea and water, so he had to exchange pleasantries with Tao Fang. After a few words of small talk, Lao Yuanchang said with a chuckle:
"When I came this morning, I guessed that Professor Tao and I had met the same person. It turned out to be true. Comrade Xiao Wang, I didn't expect you to submit five papers to Science China Mathematics."

From the acceptance of "Properties of Moment Estimation of Parameters of Ek/EI/C/Queuing Systems" on May 31st to now in August, Wang Duoyu has successively accepted five papers, one of which is "Computer Approximate Solution of Nonlinear Differential Equations" which was rejected by other journals.

The paper "Computer Approximate Solutions of Nonlinear Differential Equations" can actually be said to be in the same vein as the paper "Numerical Method for Calculating Periodic Solutions" he wrote earlier in Beijing. The only difference is that the former makes full use of the functions of computers to give numerical solutions to nonlinear differential equations, and then constructs approximate formulas based on the information of the numerical solutions, and then uses the numerical solutions to test and correct the methods.

It sounds complicated, and it is actually not simple, but this method can be used to obtain relatively accurate approximate solutions over a large range, and by conducting experiments on important mathematical models, valuable results can be achieved.

In other words, what Wang Duoyu had said to Lao Yuanchang before about using mathematical models to lock in the technical parameters of chromium-molybdenum high-alloy steel was not just a trick, but had a real mathematical theoretical basis.

It’s just that Wang Duoyu doesn’t have a computer, and today’s computers are really lousy.

"Professor Lao, five papers are not many, because the royalties are not that much." Wang Duoyu laughed and said modestly. Using the royalties to "tarnish" the value of mathematical papers is purely idleness.

Tao Fangqi took the opportunity to say, "Comrade Wang, if you come to work at the Institute of Mathematics of the Chinese Academy of Sciences, I can make you a Level 12 researcher right now, with a monthly salary of 62 yuan. How do you do that?"

A monthly salary of 62 yuan was certainly not low in 1978, but Wang Duoyu really looked down on it, because he only received 60 yuan for writing a 20,000-word manuscript, and 20,000 words only took him about two days to write.

So he refused without hesitation, "Professor Tao, I'm sorry, I really don't want to go to your Chinese Academy of Sciences. I'm sorry to bother you with this trip."

"Comrade Wang, maybe you don't know much about our Chinese Academy of Sciences. Let me give you a brief introduction to our Chinese Academy of Sciences." Upon hearing this, Tao Fangqi was immediately annoyed that he was too anxious. Then he introduced the Chinese Academy of Sciences and brought up Chen Jingrun as an example.

As a result, Wang Duoyu showed no expression on his face, because he really didn't want to go to the Chinese Academy of Sciences, so he could only politely refuse the other party again.

Wang Meili and others who were standing by were secretly anxious when they heard this. Although Wang Duoyu was a good writer and his royalties for half a month were 320 yuan, in the eyes of Wang Meili and others, that was definitely not as good as the 62 yuan monthly salary from the Chinese Academy of Sciences, because this salary was guaranteed to be profitable and was obviously more stable.

But they had no way to make the decision on Wang Duoyu's behalf and could only watch and worry.

Then at this time, the eldest son of the Wang family, Wang Shoucheng, came. The eleventh daughter, Wang Meili, was immediately overjoyed and hurriedly called him "big brother", which immediately attracted everyone's attention.
