"Zhen Ning, Jiaxian, hello. I didn't expect you to be here." Hua Luogeng walked into the office after class. When he saw two courteous young people, he was startled for a moment, a little surprised, and nodded with a smile.
There were no other mathematics professors in the office. Only Yang Wuzhi was sitting upright on his seat. Standing next to him were two teenagers. One was Yang Zhenning, the son of his familiar mentor, and the other was Yang Zhenning's classmate Jiaxian.
"Uncle Hua, Jiaxian and I encountered some problems in our studies. We took advantage of today's Saturday to come back to find our father to solve our problems." Yang Zhenning, a young man, explained.
The young man Jiaxian on the other side said nothing and stood quietly, looking at Hua Luogeng with a pair of clear and bright eyes, showing a hint of respect.
For the young Jiaxian, Hua Luogeng, who had already become a professor at National Tsinghua University at a young age, was his idol and goal, and he both respected and admired him.
"Zhen Ning, Jiaxian, I'll stop here for the time being with your questions. Go back first and I'll have a chat with your Uncle Hua." Seeing the document in Hua Luogeng's hand, Yang Wuzhi, who was reviewing the document, put down his Parker pen and said,
He turned to look at the two teenagers and said.
"Goodbye, Uncle Hua."
"Goodbye, Uncle Hua."
After hearing what their father said, the young man Yang Zhenning and the young man Jiaxian understood each other, felt a change in the atmosphere, nodded, said goodbye to Hua Luogeng, and left the office.
"Zhen Ning, Jiaxian, goodbye." Hua Luogeng said with a smile.
After the two teenagers left, the office returned to calm.
"Luo Geng, if it's still the same thing, don't mention it. I won't work for the Secret Service."
Yang Wuzhi sat upright with a serious face and took the lead in emphasizing his position to Hua Luogeng: "Besides, I also advise you not to wade into that muddy water, or you may get into trouble."
Working for the Blue Clothes Society's Secret Service was not in line with his concept of doing things, and he was unable to overcome the hurdle in his heart.
He is a university professor, the first Ph.D. in mathematics in Chinese history, and one of the important pillars of the National Mathematics Center. He has his own identity and status.
What's the point of getting involved with those guys from the Blue Clothes Club's Secret Service?
Regardless of whether it is for profit or from a personal perspective, in short, he, Yang Wuzhi, will never work for the Secret Service.
He didn't want to have a bad relationship with Hua Luogeng, nor did he want to work for the Secret Service, so he just spoke up.
"Teacher, this is not the case. Luo Geng is looking for you this time for another matter." Hearing the words of his mentor Yang Wuzhi, Hua Luogeng shook his head gently and went straight to the point.
When Yang Wuzhi heard this, he was stunned for a moment and said curiously: "Oh? You said that as long as you don't mention this matter, other things will be easy to handle."
"Submit to the Journal of Tsinghua University." Hua Luogeng responded.
Yang Wuzhi immediately became interested: "Luo Geng, have you made any new achievements recently?"
"It is not my achievement, but my apprentice's name is Yu Hua. He is a mathematical genius. He recently wrote a mathematical paper on reconstructing Lebesgue integral. I think the quality of the article is very high and meets the journal submission standards, so I
I am going to submit an article to him, and I came to see you today because I want to refer to your opinion." Hua Luogeng said with a smile.
His mentor Yang Wuzhi, who is a full professor in the Department of Mathematics at Tsinghua University, is one of the veteran reviewers for the natural science edition of the Tsinghua Journal. He mainly deals with articles on mathematics and physics. Basically, all submissions in the field of mathematics and physics will be reviewed by Yang Wuzhi.
Hua Luogeng thinks that Yu Hua's mathematics paper is very well written and has a certain degree of academic value. If it is recognized by Yang Wuzhi, the manuscript will be basically stable.
In a sense, this is an informal journal review.
Of course, as a full professor, Hua Luogeng is a new reviewer for the Natural Science Edition of Tsinghua University, and he is also mainly involved in mathematics and physics.
"I didn't expect you to come through the back door today. It's the first time I see you care so much about a student. Reconstructing the Lebesgue integral is interesting. Where is the article?"
After hearing Hua Luogeng's explanation, Yang Wuzhi finally came to his senses and couldn't help but smile: "However, I have something to say first. If this article is to be used through the back door, the quality must be excellent."
"Here it is." Hua Luogeng handed over the manuscript of his mathematics paper with a smile on his face.
Yang Wuzhi took the manuscript of the paper and put it in front of him. He briefly reviewed the format and title, which basically met the requirements of the paper. After checking, he turned his attention to the beginning. After a concise and direct explanation, a series of mathematical formulas and symbols
The proof process of composition comes into view.
When reviewing mathematics articles, we mainly look at two parts - the proof process and the logic. There should be no errors in either of them.
Whether it is the proof process or logic, one mistake can lead to death.
However, there is not a single error in this article yet, and as far as the proof process seen so far is concerned, everything is correct.
As time gradually passed, Yang Wuzhi became more and more immersed in watching. At the end, he already held the Parker pen in his right hand and took out the scratch paper to perform calculations.
Seeing his teacher Yang Wuzhi looking like this, Hua Luogeng stood aside with a smile on his face and said nothing.
"This article... is very good and could not have been written by someone who is not a master of calculus."
After an unknown amount of time, Yang Wuzhi put down his Parker pen, raised his head, and spoke with a hint of admiration. After giving an objective evaluation, he turned to Hua Luogeng with a pair of profound eyes that revealed wisdom: "Luogeng, this is really the work of your apprentice, and
Aren't you behind the scenes?"
After reading the article, Yang Wuzhi knew that the entire paper was valuable and could not be written by anyone who was not a master of calculus. He must have an extremely solid foundation in calculus to reconstruct it.
"You know that there is no point in cheating in mathematics. You will know it whenever you try it." After hearing what his teacher Yang Wuzhi said, Hua Luogeng knew that the manuscript was stable and said with a smile.
"Luo Geng, which school is your apprentice Yu Hua from? The Department of Mathematics at Peking University or the Department of Mathematics at Yan'an University? I still know the level of Tsinghua students. Except for a few top students, others may be able to understand Lebesgue.
Integral, but it is impossible to reconstruct." Yang Wuzhi fell silent. The fact is indeed as Hua Luogeng said, any subject can be falsified, but only in mathematics, it is neither possible to falsify, nor is it meaningful to falsify. He shook his head slightly.
, looked at Hua Luogeng and asked.
Hua Luogeng said: "He is still a... high school student."
"What?" Yang Wuzhi's voice was full of surprise and disbelief, echoing in the office.
high,
High school student?
Yang Wuzhi couldn't believe what he heard. The paper "Reconstructing Lebesgue Integral" in his hand was actually written by a high school student.
Incredible.
It's really incredible.
"Yu Hua is currently studying in Peking No. 4 Middle School and is in his third year of high school. Luo Geng accidentally discovered it a few days ago." Hua Luogeng continued to explain.
Yang Wuzhi recovered from the shock: "So, he actually studied calculus not long ago, right?"
"Yes." Hua Luogeng nodded.
"..." Yang Wuzhi was silent, subconsciously recalling his son Zhenning who came to him today to ask about functions.
They are all in high school, so why are the differences between people so big?
Yu Hua, Hua Luogeng's apprentice, had already mastered calculus in his third year of high school, while his own son, in his first year of high school, was still tinkering with functions. The gap between the two was simply too great to be compared.
