In this way, Jiang Shuiyuan honestly picked up the chemistry Olympiad materials that had been eaten for a long time and started to study again. There is no way, things have risen to the height of affecting the relationship between father and son, and the dignity and personality of the father, for the sake of the filial piety of the father and the filial piety of the family and the harmonious, healthy and sustainable development of the family, Jiang Shuiyuan can only compromise.

The next morning, Pu Xiaoxiang saw Jiang Shuiyuan doing the chemistry Olympiad test papers, and smiled like a Samoyed who had abused a husky, and his eyes were bent into a crescent moon. Jiang Shuiyuan knew that this matter was absolutely inseparable from this little girl, but he was really smart, and as soon as he made a move, he pinched his father's pulse, and he could only retaliate with personal attacks: "Hey, someone please be a lady, your molars are leaking out of your laughter!"

"Not really!"

Pu Xiaoxiang pursed his pink and tender mouth, turned around and took out a large stack of materials like secret scrolls and internal questions from his schoolbag, and piled them on the table of Jiang Shuiyuan: "Some of these were recently sent by the Olympiad Society, and some of them were obtained by my friends from everywhere, and I don't know if they are useful or not, I will give you a copy by the way, do you want to see it?"

The girls are very careful, not only do they bind each test paper neatly, but they also use colored paper clips to classify them, paste fluorescent labels, indicate the source of the test papers, their own feelings about doing the questions, and so on. Jiang Shuiyuan felt that a soft place in his heart seemed to be gently scratched by a feather a few times, and after a moment of silence, he asked, "How much is the photocopying fee?"

"Do you really want to give money?" Pu Xiaoxiang stared at Jiang Shuiyuan with a straight face.

Jiang Shuiyuan's straight male cancer has finally not reached the advanced stage: "Then Blessing Building?"

"That's what you said!" Pu Xiaoxiang's expression instantly became vivid, "I want to eat squirrel guiyu, Wensi tofu, as well as crab roe soup dumplings and braised silver carp heads! After eating, you have to accompany me to the bar to sing!"

Jiang Shuiyuan said: "It's okay to eat." I'm afraid I'll be shot by General Puda!"

"Aren't you alive and well now?"

Jiang Shuiyuan instantly understood, and immediately said, "I can explain the matter of going to the bar-"

"You don't have to explain it to me. ”

If I don't explain, I'm afraid I'll be smoked into tracheitis by the smell of your vinegar in a few minutes! Immediately, Jiang Shuiyuan came back to his senses: No, why should I explain to her? Obviously it's just a kiss, how can it be as if you have received a certificate?

Although Jiang Shuiyuan thought so in his heart, his mouth was very honest: "That's the case, at that time, our workshop was almost over, and everyone was ready to go back, and it happened that a boy in our dormitory fell in love with a girl in the class, so he organized two dormitories to have a friendship. The boy probably wanted to have some atmosphere, so he chose the bar next to the school—"

"It's only been a few days since the class, and the competitive pressure is so great, and there are still people who love me and me?" Is it love at first sight?" Pu Xiaoxiang's focus began to deviate, "Then have you met a girl you like in the class, or a girl likes you?"

Jiang Shuiyuan hurriedly cleared himself: "You also know that the competition pressure in the workshop is high, I get up early all day and work in the dark, so busy that I even have to eat and sleep carefully, how can I have time to care about this?"

"Really?" Pu Xiaoxiang's tone was a little playful.

Could it be that this little girl has heard some strange rumors again? It seems that I have been very defensive like a jade during this time in the capital! When Jiang Shuiyuan was trying his best to reflect, the rescuer came: "Jiang, Jiang, Jiangshuiyuan, Ge, Ge, Teacher Ge is looking for you!"

Jiang Shuiyuan burst into tears, and almost awarded Zhang Jin a medal for righteousness and courage on the spot: "Okay, I'll go right away!" After speaking, he got up and walked out. Anyway, he has never been so eager to see Uncle Ge!

"Remember the Blessing Building!" Pu Xiaoxiang reminded.

"No problem!"

"And the bar, the singing. ”

"Wait until you're eighteen years old!"

"Eighteen, what are your intentions?"

Jiang Shuiyuan, who walked to the door, staggered: "What an attempt to be a ghost! It is a law that laws prohibit people under the age of 18 from entering and leaving commercial entertainment venues." Also, if you have time, learn more law, and don't keep thinking about what you don't have!"

As soon as he returned to Huai'an Mansion, Uncle Ge returned to his usual sloppy style, crumpled clothes, unkempt hair, gray sneakers, from the inside to the outside are filled with the decadent atmosphere of a single dead fat house, the image of the suit and leather shoes in the capital a few days ago is like a colorful soap bubble, as soon as it lands, it will be shattered, and it will disappear like a sigh of youth at the moment of the forty-year-old middle-aged morning.

"Teacher Ge, are you looking for me?"

Uncle Ge raised his head: "It's not me looking for you, but you should be looking for me." Since you don't take the initiative to find me, I have to look for you first!"

Why did a good math teacher become a rap singer after not seeing him for a few days? Is this a distortion of human nature or a moral degradation? Jiang Shuiyuan is puzzled. Uncle Ge didn't realize it, and casually clicked on a bunch of things on the corner of the table: "Inside this hard drive, there are works from the magazine's inception to the end of last year. Mathematics full-text database. I'm afraid you'll be lazy, so I'll help you print the previous years first, and you can take it back and take a good look. ”

Jiang Shuiyuan rubbed his hands: "Thank you, Mr. Ge! It's really troublesome for you, that, that, how much does it cost to print?"

Uncle Ge looked at him with disdain: "Do you think Mr. Ge is the one who is missing that little money? If you really have a heart, just give me a serious look when you read it, don't look at the Internet, and sweep hundreds of thousands of words in a day." ”

"I'll study it carefully!"

Uncle Ge shook his head: "I asked you to read carefully, not to let you check and fill in the gaps, deliberately find mistakes, nor to train an expert in the history of mathematics, but to let you discover the innovation of methods, the breakthrough of wisdom and the flash of inspiration." Although the early papers were relatively crude and naïve, in the eyes of people at the time, they were all trying to make breakthroughs and inventions. Just as Newton sensed gravity from the apple falling to the ground, and Mendeleev discovered the periodic table from disparate elements, which now seems natural and logical, it was groundbreaking at the time. So when you read it, you should focus on discovering the true value of it, and it is best to take it with this book of Victor Kaz's "History of Mathematics", the effect is even better. ”

Jiang Shuiyuan found that there was a thick English textbook under the printing paper, which was Kaz's "History of Mathematics". He took it and roughly scanned the catalog, and said with a smile: "The mathematics we are learning now is roughly equivalent to the level of the beginning of modern mathematics in the 18th and 19th centuries, and this set of "Mathematical Yearbooks" is really the most suitable for me!"

Uncle Ge said: "That's because you read a few more college textbooks, so you can barely have the current level, if you are an ordinary high school student, many people are still stuck in the 17th century." This is also the charm of mathematics! Many of the knowledge points in our current high school biology have been discovered in the past 50 years; high school chemistry, many knowledge points have been discovered since the 20 th century; and high school physics, many of which have been discovered in the 19 th century. Mathematics is the only thing that remains between antiquity and the Middle Ages, and it has not become obsolete for hundreds of years, and even decades or hundreds of years later, it will still be taught in schools!"

Er Cao's body and name are destroyed, and the rivers and rivers will not be wasted!

Jiang Shuiyuan finally felt the eternity and charm of mathematics, as well as the difficulty of learning mathematics: "In other words, those scientists who are engaged in mathematical research have to learn step by step from the Middle Ages, and they have to follow the footsteps of their predecessors for two or three hundred years before they can touch the frontier of the discipline." Not to mention how many people have contributed in the past two or three hundred years, just thinking about such a long time span makes me feel a lot of pressure!"

Uncle Ge coughed several times: "This, this, it's not like you think." If you have read this "History of Mathematics", you will know that in fact, many times we are still studying and solving problems left over from the 17th and 18th centuries, such as the Waring problem, which was proposed by Walling in 1770 in "Algebraic Meditations", such as the Fermat conjecture, which was conceived by Fermat in 1637 when he was in the "Arithmetic" of the Diophantus, and the Goldbach conjecture, which was put forward by Goldbach in a letter to Euler in 1742. Although two or three hundred years have passed, and we have created many mathematical tools and proposed many mathematical theories, we are still one step away from the final solution. So don't think that the time span is long, like the Riemann hypothesis, it may take decades or even centuries to reach a conclusion. ”

"Uh...... The problems of two or three hundred years ago have not been solved, and they are really not as difficult as ordinary two!"

Uncle Ge was furious: "Let you see, you just look at it honestly, what are you doing so much crookedly? Human beings have been thinking about 'Who am I, where do I come from, and where are I going?' since human beings have ever thought about it, and if they have not been solved now, are the people who study philosophy and science no longer alive?"

yes, so all the people who think about these three questions are dead, or on their way to death!

Jiang Shuiyuan can be imagined, if he answers like this, Uncle Ge will definitely explode in minutes, and the saliva spewed out can cause locally heavy rain. In order to avoid flooding, he wisely avoided this topic and asked shamelessly, "Teacher Ge, is there anything to pay attention to when reading these papers?"

Uncle Ge shook his neck: "Since you want to see it, the first thing is to figure it out, not only to know what it is, but also to know why it is true, and really read through it to understand." If you don't understand something, you can go to the library to look up the information, and if you don't understand it, you can write it down in a notebook, put it aside, and ponder it slowly when you have time. You don't need to be fast to read papers, but at that time, the level of mathematics in the United States was very average, and the "Mathematical Yearbook" was published by the University of Virginia in the early days, and at that time, it was also the "Journal of Mathematics in the United States" founded by Sylvester. Now that there are still four or five months before the start of school in September, no matter how much you grind, you should end the Qing government and enter the Republic of China before you go to university, right?"

The Annals of Mathematics was founded in 1884, but the Qing government closed its doors in 1911. In other words, Uncle Ge's summer vacation homework is to read the content of the previous 28 years. Jiang Shuiyuan didn't know how many issues of the early "Mathematical Yearbook" were published a year, how many papers were published in each journal, and what the level of papers was, but the task assigned by Uncle Ge was not easy to estimate.

But what Jiang Shuiyuan didn't know was that the pit dug by Uncle Ge was actually deeper than the Mariana Trench!

It is true that before 1880, the level of mathematical research in the United States was very average, except for Peirce of Harvard University and Gibbs of Yale University, which had a certain influence on the world, and the others were not worth mentioning. However, after 1880, as the economic power of the United States took off, the investment in natural sciences also increased, and the level of scientific research changed with each passing day.

Taking mathematics as an example, the major events around 1880 included the establishment of the New York Mathematical Society (1888, soon renamed the National Mathematical Society), the founding of the American Journal of Mathematics (.), the journal "Annals of Mathematics", and the establishment of Johns Hopkins University (1876) and the University of Chicago (1892). By the beginning of the 20th century, the level of mathematics in the United States had been on a par with that of advanced European countries.

With Jiang Shuiyuan's current undergraduate level of half-hung university, it is conceivable that he will definitely have to use his strength to complete the task.
