Ge Juntian saw Jiang Shuiyuan accept the small book he brought, as if he saw the fish swallowing the sweet bait, and said a few words, so he left satisfied. Before he left the classroom, Wu Zichen immediately came over and asked very doggedly: "Boss, who is the Uncle Tu Feiyuan who yelled at you just now? At that time, I was still five steps away from him, and I could smell the obscene smell coming from my face!"

"You don't know him, I think he abused countless people in the whole house, crying wolves, and his body was incomplete!"

"Ahh

"Phew, you know you can't spit ivory out of your dog's mouth. Don't say you know me in the future, I can't afford to lose this person!" Jiang Shuiyuan looked at Wu Zichen with disdain, "Don't look at this Tu Feiyuan uncle's sloppy and uninhibited appearance, but I want to say his name, and I will be sure to frighten the third year of junior high school and the first year of high school in the whole house!

Wu Zichen was so frightened that he hurriedly patted his chest: "I'll take it, it turns out to be him! What kind of thing did he give you? Tattered, could it be the college entrance examination winning book, the ancestral martial arts secret book? It's not like it!" he said and snatched the book "Hilbert's Problem and Research Progress", only to see that he flipped a few pages indiscriminately and threw the book away, covered his eyes with both hands and shouted: "It's over, boss, I'm blind! I have to wash my eyes immediately!"

Cai Xiaojia picked it up and flipped through a few pages, and then his head was also full of black lines, and said weakly: "This book is estimated to be understood by the squad leader......

"Really, I'll take a look!" Wei Chumo was a little unconvinced, and took the book and turned it from the first page. It must be said that Wei Chumo is very clever, because most textbooks start with either a series of fascinating anecdotes or a series of esoteric theories from the most obvious questions. Of course, the Hilbert problem is no exception.

The total of 23 problems proposed by Hilbert can be divided into four major blocks, the first to sixth problems are mathematical foundation problems, the 7th to 12th problems are number theory problems, the 13th to 18th problems are algebraic and geometry problems, and the 19th to 23rd problems belong to mathematical analysis problems. However, as an outstanding mathematician at the beginning of the 20 th century, even if Hilbert casually threw out a problem, it was enough for ordinary middle school students to scratch their brains, not to mention the problems of the century that he specially listed for mathematicians all over the world?

Moreover, this book "Hilbert Problems and Research Progress" is not aimed at ordinary middle school students, but a specific group of people who are above the graduate level of mathematics and are interested in devoting themselves to mathematical research, so the opening directly bypasses Hilbert's life resume and the origin of Hilbert's problem, -- perhaps in the opinion of the author Academician Hui Chengze, Hilbert and the Hilbert problem are simply like engaging in physics and being familiar with Newton and Sun Yuanqi, and studying history to understand Qin Shi Huang and Emperor Wu of the Han Dynasty. Spending three or five pages on Hilbert or Hilbert questions is a complete insult to the reader's IQ!

So on the first page, Wei Chumo sees "Problem 1: Cantor's Continuum Cardinality Problem", and then begins to introduce this problem below:

In 1874, the German mathematician G. Cantor guessed that there was no other cardinality between the columnable and real bases, which is known as the continuum problem (Continuum_Hypothesis, often denoted as CH). This involves some fundamental problems in infinite sets, infinite cardinality. In the comparison of many infinite sets, what is the criterion? Cantor proposed to distinguish the "size" of sets according to one-to-one correspondence, and the sets that have a one-to-one correspondence with the set of natural numbers are called countable sets, and the cardinality of such sets is defined as ?0, and the cardinality of the set formed by collecting all the sets with the cardinality of ?0 is ?0, and so on, an infinite cardinal sequence can be obtained......

Wei Chumo was sure that he knew every Chinese character, but he didn't know what to do with it, especially the endless mathematical terms, which gave him a headache. After just a few lines, brain cells have shown signs of large-scale death. If you keep holding on, you can't be sure that your brain will crash due to overclocking!

Well, it must have been me who opened it in the wrong way, and I ran into the hardest problem in the whole book without paying attention, maybe the next one will be much easier!

With this in mind, Wei Chu silently turned to the second question. When he saw the title "The Non-Contradiction of the System of Axioms of Arithmetic", he instantly collapsed: "Arithmetic" I understand, "Axiom" I have learned, and "System" I also roughly know what it means. But can any of you explain to me what the hell is the "axiom system of arithmetic"? Can you speak human language?

Wu Zichen saw his embarrassment from Wei Chumo's expression, and said mercilessly: "How about it, great mathematician, can you understand what is written in the book?

"The book is here, if you want to open your eyes, you can read it yourself, what is the taste of eating other people's chewed buns?" said Wei Chumo and threw the book on Jiang Shuiyuan's desk.

Wu Zichen was very disdainful of his pretense and pretentiousness, and shook his head and said: "Knowing is knowing, not knowing is not knowing, it is knowing; If you don't know what you know, the higher the pen grid, and if you see a beautiful woman and you know everything, the more obvious the pen will be. Once the cow pen is exposed, the skin is exposed, and the face is swollen, then the pen is loaded and becomes stupid!"

"You!" Wei Chumo's face was flushed and his eyes were red, if it weren't for the fact that his own force value was too low, he would have rushed up to meet Wu Zichen a long time ago.

Jiang Shuiyuan frowned and scolded: "Wu Zichen, can you be a little more civilized? Look at your foul mouth, it is estimated that more than half of China's environmental pollution problems are directly related to your mouth! Quickly apologize to Wei Chumo, and then honestly go to self-study in the morning, today is the head teacher to watch the class, if he catches it, it will definitely be as good-looking as you!"

Someone is so careless, just mentioning his name one second, and appearing in front of you the next. Jiang Shuiyuan watched Zhu Qingjia appear at the door of the classroom, and then walked over, and finally stopped beside him, and asked in a harmonious voice, "Jiang Shuiyuan, have you finished your composition?"

"Composition?

Zhu Qingjia chuckled and said, "I told you as early as the beginning of the school year, and I reminded you a few days ago, you shouldn't have forgotten jì, right?"

"Ahh

After Zhu Qingjia's reminder, Jiang Shuiyuan understood. But he only remembered that Zhu Qingjia did tell him once when school started, but he didn't remember what he reminded him a few days ago. Could it be that my memory is broken? This answer is not only Jiang Shuiyuan himself does not believe it, but Zhu Qingjia does not believe it either, I am afraid that even all the people in Huai'an Mansion who have heard of his famous name will not believe it!

With the intensification of the difficult selection competition of Chinese studies, coupled with the deliberate spread of some people, Jiang Shuiyuan's reputation for never forgetting and being able to recite the "Thirteen Classics" and "Twenty-four History" has also spread. In the previous matches after the duel with Pingqiao No. 2 Middle School, almost no one dared to ask Jiang Shuiyuan questions in the free debate session. It's very simple, with such a great god who has drowned in history, this is not a deliberate uncomfortable problem, but the old birthday star eats arsenic - life is impatient!

You say that such a great god can forget the things that the head teacher told him repeatedly, isn't that going to the grave to burn the newspaper - fooling the ghost?

"You really forgot, right?" Zhu Qingjia was a little annoyed.

Jiang Shuiyuan secretly smiled bitterly: It's not that I forgot, but I'm so busy these days that my head is dizzy and my feet don't touch the ground, and my head is thinking about competitions and writing books all the time.

Just when Jiang Shuiyuan was about to confess and apologize, Cai Xiaojia suddenly said: "Mr. Zhu, Jiang Shuiyuan has already written two modern poems for the competition, but they are written on manuscript paper and are messy, so let me help him copy them." He hasn't asked me these days, and I've been forgetting to give it to him. Look, here!" As she spoke, she took out a page of scented colored letterhead from her diary and handed it to Zhu Qingjia, on which she neatly copied two small poems that Jiang Shuiyuan had scribbled by hand not long ago.

"Oh, Jiang Shuiyuan can also write modern poems, then I want to take a good look at it!" Zhu Qingjia suddenly became interested, took the letter and read it carefully.

Both poems are very short, and Zhu Qingjia finished reading them in minutes, but he chewed on them for a long time before he said slowly: "The poems are very short, but they have a long charm, and each has its own merits." The first poem, though only three lines, is delicate, philosophical, and evokeful, and can be understood as a poem about possibility, or as a fog of uncertainty. The second poem is a little longer, but it is only five lines, with beautiful imagery, elegant diction, and a peculiar imagination that is refreshing and lovely.

These two poems are indeed new ideas and new expressions, which are very suitable for the theme of the New Concept Essay Competition, and as long as the judges read them carefully, they will definitely not let go of such a superb work. I really didn't expect that our Jiang Shuiyuan students not only knew ancient Chinese words, but also wrote modern poems extraordinary, and they were really capable of anything. It's just—"

"Please Teacher Zhu don't hesitate to teach!" Jiang Shuiyuan's posture is very correct.

Zhu Qingjia shook the scented colored stationery: "Are you sure you want to use such stationery to submit? This is a submission, not a love letter!"

Cai Xiaojia instantly blushed to the base of her neck, and almost didn't bury her head under the table.

"The second point, since you write poetry, what about the title of your poetry?" Zhu Qingjia continued.

Jiang Shuiyuan didn't want to bother too much: "Why don't you learn from the ideas of your predecessors and call it "Untitled" or "Broken Chapters" directly?"

"It's inappropriate, it's inappropriate!" Zhu Qingjia shook his head again and again, "Whether in terms of meaning or language, your two poems are independent of each other. If you treat them as two parts of a poem, it not only reduces the readability of the poem, but also affects the expression of ideas. Otherwise, let's refer to the tradition of the "Book of Songs" and "Nineteen Ancient Poems", and name it after the first line of each poem, the first poem is called "This Road Maybe", and the second poem is called "I Thought I Saw a Letter Dropped on the Porch". How?"

You've mentioned yì like this, can I still say it's bad?
