In the teaching building, there are more and more students coming and going, and classes are about to start.

"Who is this, it's so dragged, Tsinghua is okay, Peking University is okay, right? Do you think Qingbei is opened by your family?"

"Isn't that who?"

"Who's who?"

"Shen Qi, the provincial mathematics champion!"

"The guy on the banner in the administrative building?"

"Yes, yes, it's him, the sophomore (2) class of high school. ”

"Xueba. ”

A few girls passing by were talking, looking back at Shen Qi as they walked.

"Hello girls, are you about it?" Shen Qi waved to the girls.

Giggled, the girls laughed a few times and ran away.

Director Nie laughed playfully: "Shen Qi, you didn't dare to flirt with girls in school so blatantly before. ”

"I used to have bad grades, and I always felt inferior. Shen Qi told the truth.

"Even if you have good grades, you are not allowed to fall in love. Director Nie put away his smile and said solemnly.

"Knowing Director Nie, you should focus on your studies in high school. ”

"Okay Shen Qi, it's almost class, you go back to the classroom first, and consider the suggestion I just made. ”

Back in the classroom of the second (2) class of high school, Shen Qi was greeted by various worships.

"Shen Qi, full score. ”

"Please take my knees. ”

"How can I get a perfect score every time?"

"How do I become a math champion?"

The classmates envied, praised, and asked for advice.

"This kind of thing is a casual test, mainly depending on the state. Shen Qi sat down in his seat, took out his book and prepared for class.

"If you don't pretend to be forced, we can still be friends. The classmates were worshipping Shen Qi just now, and now they don't want to talk to him.

The stars change, spring goes to summer.

It's June, the hot summer.

Recently, he has been studying Acta Mathematica Sinica, a journal published by the Chinese Mathematical Society, and the Journal of Mathematics published by Wuhan University, which are the core journals of mathematics in China, and the tone of the papers is very much to Shen Qi's appetite.

He has also read Peking University's "Mathematical Research" and Fudan University's "Mathematical Yearbook A", and the overall feeling is that the latter two books are not as incisive and profound as the first two books.

If you can publish one or two mathematical papers in any of the four major in China, take the journal that published your paper to the School of Mathematics or Science of any university in China, and say I want to come to you for graduate school, give it a chance...... The Faculty of Mathematics or the Faculty of Science will definitely tell you, come on, boy, Baoyan.

Shen Qi's current level of mathematics is still a certain gap from taking the journal to the research institute.

He just took a look, opened up ideas and patterns, and studied the insights of domestic mathematical elites on mathematics.

To understand all the papers in Acta Mathematica Sinica, you must have a certain mathematical foundation, otherwise it is like reading a book from heaven, you know all the words, but you don't know what they mean.

The extracurricular interaction between Shen Qi and Zhang Wanbang continued, but Shen Qi found that Zhang Wanbang's reply was getting slower and slower.

In the past, Zhang Wanbang could write something for Shen Qi every day, but now, he wrote more than 100 words in a week, and the last sentence was "I have nothing to teach you anymore, and the subject of mathematics mainly relies on self-study."

Think about it, Shen Qi's math index is already level 4, and Zhang Wanbang is defined by the system as a level 5 reference template, the teacher and student are 1 level apart, and when the master always has to keep both hands to watch the family's unique skills, Zhang Wanbang said that there is nothing to teach Shen Qi, and he can understand.

"So one day I will graduate from the newcomer village and embark on a new journey of solitude alone, and this day will come a few months earlier than I expected. ”

On June 25, Shen Qi packed his bags and went alone to the northern suburbs resort, 38 kilometers away from his home, where he will receive a week-long closed training camp for the provincial team.

The Nanyue Provincial Mathematics Competition Team has one team leader, one deputy team leader, one liaison officer, and six team members.

All six team members have been assembled in the northern suburbs resort, the oldest of them is 18 years old, the youngest is 16 years old, and the six of them are the best teenagers in the province in this age group.

The reason why the training camp is located in the suburbs is because the mountains and rivers are beautiful and it is very quiet.

Shen Qi is satisfied with the logistics arrangement, there is food, drink and WIFI, and the two live in a standard room.

The closed training was not as Shen Qi expected, all the team members were locked in a small dark room, giving me questions, doing questions, and not giving me meals if I couldn't solve the correct answers.

In fact, the training course is only 4 hours a day, and the rest of the time the players love to play mobile phones, play games, read novels, and have free activities.

The team leader is the vice president of the Provincial Mathematics Society, who is responsible for the daily teaching.

"Can anyone tell me what the essence of a function is? "The Vice President asked a question in today's lecture.

"To put it bluntly, functions are the study of change and invariance. Shen Qi was the first to speak.

"Oh, yes, do any other students have anything to add?" asked the vice president.

The other team members shook their heads and nodded, agreeing with Shen Qi's opinion.

Shen Qi is right, functions are the study of change and invariance. Next, let's go into the following sections, permutations, and combinations. ”

For three days, the vice president only talked about concepts and not specific topics, and he believed that teaching students one way of thinking is more effective than teaching them to do 100 questions.

"Okay, that's all for today's professional teaching, and then I want to talk about some light content, you have been learning mathematics since the first grade of primary school or even kindergarten, so do you know what era mathematics first appeared and who invented it?"

It was Shen Qi who was the first to speak: "I have watched the science and education film of the Central Station, putting aside the way of primitive people bartering, mathematics in the real sense first appeared around 3000 BC, either invented by the ancient Babylonians or the ancient Egyptians, and there is controversy in the history of mathematics." Anyway, it is impossible for either the ancient Babylonians or the ancient Egyptians to build hanging gardens and pyramids without applying mathematical knowledge, mathematical knowledge in the true sense of the word, rather than exchanging a cow for a sack of grain. ”

"Personally, I prefer the ancient Babylonians, of course, what I said doesn't count, just to talk to my classmates. The vice president wrote some strange symbols on the blackboard and asked, "Do you know what I'm writing?"

The other five teammates looked dazed, and Shen Qi was also puzzled, he could only guess: "Cuneiform?"

"Yo, Shen Qi, can you even read cuneiform characters?"

"I don't understand, I'm just guessing that this is an ancient Babylonian cuneiform, Mr. Tian, didn't you just say that you were biased towards the ancient Babylonians. ”

"That's right, it's cuneiform from ancient Babylon. "The vice president's surname is Tian, and Shen Qi calls him Teacher Tian.

As he spoke, Mr. Tian became unhappy: "The six of you are a team, a team! Why is Shen Qi always speaking alone? A few of you will also express your views on ancient Babylonian mathematics. ”

"We ...... I really don't know, and I can't pretend to know. "The team members expressed their helplessness, let's talk about functions when we talk about functions, what the hell are you talking about cuneiform?

"Hey. Teacher Tian sighed, this team has a little hope to achieve good results in the national arena, and only Shen Qi is the only one, Shen Qi's vision, knowledge and thinking are better than the other five team members, which is very important for mathematics, "Shen Qi, you continue to guess, is this string of cuneiform characters I wrote meaningful?"

Shen Qi studied for a long time and said: "I don't know if it has any meaning, but I guess it has something to do with mathematics? Judging from the cuneiform characters drawn by Mr. Tian, there is a certain regularity, and the first symbol to the tenth symbol is completely different." But the latter few symbols appear partially identical, so Mr. Tian wants to teach us the decimal system?"

"Do you know the decimal system?" Mr. Tian was slightly surprised, but thinking that Shen Qi was the provincial champion, there was nothing to make a fuss about knowing the decimal system.

Shen Qi nodded: "I know one thing, the protagonist in "The Martian" was trapped on Mars, and just when he was about to hang up, he relied on the decimal system to get in touch with the Earth Headquarters, and finally escaped and returned to Earth. I've been obsessed with science fiction lately, the hard science fiction kind. ”

"The decimal system was also invented by the ancient Babylonians, it's not very difficult to understand, now I want to talk about the hexagesimal system, you should listen to it as a hobby, expand your knowledge, it doesn't matter if you don't understand it. I know that you are all top students in your respective schools, but the top students are not just brushing questions, those who can only brush questions are fake school masters, and the real top students must understand the pattern of two words--- Mr. Tian continued to draw his ancient Babylonian wedge-shaped mathematical symbols, and his research on ancient mathematics was similar to Kong Yiji's fennel bean character, which was difficult to find a soulmate.

And now, Mr. Tian has a little bosom friend, and Shen Qi is listening to him talk about the mathematical dynasty 5,000 years ago......
