After drinking and singing, parting is just around the corner.

Wei Xiao is from Beijing, Jiang Shuiyuan, Hu Peiwei and Mei Lin will stay in Beijing to participate in the National Olympiad finals, and everyone else will pack their bags and go home. As for the future, Wei Xiao, Yan Ping, and Wei Shan should fight again, even if there is little hope, after all, there is still hope. And Zhang Yuanheng, who directly broke into the military administration zone and asked to meet the emperor, may be blacklisted for life by Jingshi University, right?

Hearing that the workshop was over, Qiao Yinuo wanted to invite Jiang Shuiyuan to have another meal, but Jiang Shuiyuan, who was afraid of causing trouble, sternly refused. The little princess also came over, and when she heard that Jiang Shuiyuan was going to stay in the capital to participate in the National Olympiad finals, she left with a disgusted face.

Jiang Shuiyuan took advantage of the spare time in the past few days to roughly scan the textbooks and exercise books on the Olympiad in the library of Jingshi University, and his confidence in his heart has barely recovered to seventy or eighty percent of the past. As a result, a chance encounter with Hu Peiwei in the library knocked him back to his original form.

It was the end of the workshop, and when Jiang Shuiyuan went to the library to return the books, he saw that Hu Peiwei was also browsing the library.

It is not surprising that Jiang Shuiyuan has encountered not a hundred of his classmates these days, but also eighty. Strangely, she went to the periodical reading room instead of the book lending library that everyone usually visits.

Going to the journal reading room?

Jiang Shuiyuan couldn't hold back his curiosity and followed him. I saw Hu Peiwei enter the reading room, drove straight to the O1 mathematics area, selected a few newly published journals and began to read. Seeing this, he also casually pulled out a few magazines from the bookshelf and walked over, pretending to meet by chance, "Yo, classmate Hu, are you there too?" What are you reading?"

Hu Peiwei showed the covers of several magazines to Jiang Shuiyuan, and saw that they were all full of English letters, and it looked like it was full of "Annalsofatheatics" (Annals of Mathematics), Ventionesatheaticae (New Advances in Mathematics), Actaatheatica (Acta Matheatheatica), and Journal of TheAricanatheaticalSociety ( Journal of the American Mathematical Society). ”

Even though Jiang Shuiyuan is lonely and unheard, he also knows that this is the top four internationally recognized and top mathematics magazines. After listening to it, Jiang Shuiyuan's whole person was not good: "The legendary 'Big Four'?

"Of course I don't understand!" Hu Peiwei replied confidently, "I have long heard of the prestige of the 'Big Four', but unfortunately our school only has some ordinary domestic journals, such as Acta Mathematica Sinica, Mathematical Research and Review, Journal of Applied Mathematics, and Journal of Mathematics. I'm bored today, so I'll come over and flip through it, and the right is to open my eyes and worship the great god. ”

What a gap!

Jiang Shuiyuan has visited the library of Huai'an Fuzhong and the reference room of the school's Olympiad Club, which also has mathematics journals, but they all focus on secondary mathematics education, such as "Mathematics Bulletin", "Journal of Mathematics Education", "Mathematics Teaching Research", "Middle School Mathematics Research" and so on. The ones Hu Peiwei just mentioned obviously belong to academic journals that publish creative papers in mathematics and applied mathematics, and they are aimed at real researchers. Perhaps, this is the gap between ordinary key high schools and Olympiad schools, right?

"Awesome! It turns out that you subscribed to academic journals in high school to learn about scientific research trends in the academic world. Jiang Shuiyuan did not hesitate to give his praise, "It seems that your school has always cultivated you as a math worker, not a math enthusiast, no wonder your Olympiad level is so high!"

Hu Peiwei shook her head: "You are wrong! We are not cultivating talents, but simply coping with exams." Our purpose is very utilitarian, that is, we hope to accumulate some good ideas or useful conclusions in the process of flipping through the journals, which can be used in future competitions. In fact, in recent years, in the finals of the Mathematics Olympiad and the International Olympiad, there have been similar situations where the conclusion of a certain paper is directly borrowed to solve the problem. ”

Jiang Shui Yuandao "put what you have learned into practice, which is understandable." The fact that you can read and master so much mathematical literature is one of the abilities in itself. ”

"But this is completely contrary to the purpose of the Olympiad. I think the significance of the existence of the Olympiad is to exercise people's thinking and logic, rather than to expand the scope of knowledge. If you simply compete in the scope of knowledge, it is better to directly test the various branches of advanced mathematics. Hu Peiwei immediately smiled, "It seems a bit funny for a person with vested interests in mathematics like me to talk about this issue." By the way, what magazine are you reading?"

Jiang Shuiyuan just wanted to show the journal in his hand, but he glanced at it and his face turned green with fright. I saw that I took a few magazines that were "Chinese Journal of Andrology", "Chinese Sexual Science", "Progress in Modern Obstetrics and Gynecology", and "Chinese Journal of Reproduction and Contraception", and hurriedly hid behind me, "Hehe, I just take a few copies of "Bosom Friend" and "Story Meeting" to relieve boredom, and I dare not be ugly in front of your 'Big Four'." Say goodbye, I'll pay respect!"

After Jiang Shuiyuan urinated, he went to return the book first, thought about it and walked into the electronic reading room, opened the database of academic journals, and found the latest issue of "Actaatheatica" from it and began to read it.

Of course, the latest installment is not much new. Published by the ITTAG-Leffler Institute of Mathematics of the Royal Swedish Academy of Sciences, the journal is dedicated to publishing "the highest quality research papers in all fields of mathematics", and publishes only two volumes and four issues a year, with about a dozen papers. So the book that Jiang Shuiyuan is seeing now has actually been published for two or three months.

As soon as he turned to the catalog, Jiang Shuiyuan was dumbfounded.

Although actaatheatica is an internationally renowned journal, it publishes articles in three languages: English, French, and German. Coincidentally, there were only two papers in this issue of Jiang Shuiyuan, one in German and the other in French. If it is Hu Peiwei, with her attainments as the champion of the French group of the National Innovative Foreign Language Competition, at least the French article can be seen. If it is a river water source, then only the tiger eats the sky - I don't know where to start.

It seems that "Actaatheatica" doesn't match me, so change it!

Jiang Shuiyuan also found "AnnalsoFatheatics" ("Annals of Mathematics"), a top mathematics journal jointly published by the Department of Mathematics of Princeton University and the Institute for Advanced Study in Princeton, which is a little better than the previous one, first of all, it is a bimonthly journal, and publishes more than 60 papers a year. Although the requirements for papers are still strict, there must be major breakthroughs to be approved by the editorial board, at least readers have more room to choose.

Most importantly, it's all in English.

Jiang Shuiyuan believes that with our full score of reading "OED" and English reading comprehension, even if we can't understand the doorway, at least we can watch a lively time, right?

Ten minutes later, Jiang Shuiyuan devastated the page. It turns out that even if you have read through "OED" ("Oxford English Dictionary"), even if you often get full marks in English reading comprehension, and you don't have enough math skills, you still can't even watch the excitement!

Is it true that the top international journals are not in line with the basic national conditions of China's education? Or is it that I have just swallowed the "Big Four" and am a little uncomfortable?

Jiang Shuiyuan thought about it for a long time and decided to go back and taste what it was like to be a domestic mathematics journal. This time, he chose Acta Mathematica Sinica, jointly sponsored by the Chinese Mathematical Society and the Department of Mathematics of Jingshi University, which is the first professional journal of mathematics in China and the most authoritative academic journal in the field of mathematics in China.

"The body and the earth are not two" really makes sense. When I opened the "Acta Mathematica Sinica", the feeling of déjà vu immediately came to my face, the kind Chinese characters, the familiar expressions, and the short length, at first glance, it was the handwriting of my own family. Although the vast majority of articles are still incomprehensible, at least it is not a problem to watch the excitement. From this point of view, as Academician Hui Chengze and Uncle Ge said, the level of mathematics in China is indeed not good.

Although it feels intimate, it still takes a lot of effort to gnaw, and the more I bite, the more I feel ignorant, and the more I bite, the more I feel that I need to make up for it. I often see a paper and don't understand it, so I go to the library to check the book, and when I come back to read the paper, I still don't understand it, and then I go back to look up the book.

The next day, Uncle Ge was taken aback when he saw Jiang Shuiyuan's eyes open, "Isn't the workshop over? How did you get it like this? Are the girls too hospitable, or are you too heroic and unrestrained? No matter what, you have to pay attention to your body!"

Jiang Shuiyuan couldn't help but glared at this old Buxiu, "Teacher Ge, if you took the college entrance examination back then, you would definitely not be able to get into Jingshi University!"

"And what are you?"

Jiang Shuiyuan yawned, "I stayed up late last night and watched a few issues of Acta Mathematica Sinica, and it became like this." ”

"You understand?"

"It's just that I can't understand it. If you understand it, you still need to stay up late?" Jiang Shuiyuan replied angrily.
