University of Göttingen, Germany.

Despite the effects of the war, Göttingen still has one of the best programmes at the school, the regular weekly meetings of the Mathematics Club.

The Math Club is a free space for math activities. The club is not organized and has no person in charge. There are no members and there are no fees. Since the club is based in Göttingen, and Göttingen's fame makes the club speaking a very high-class event. Foreign scientists often come here to report on their recent work, but more often it is Göttingen's own people, who are free to give speeches and report on their new achievements and ideas.

As usual, Hilberta lowered the brim of her hat, found a random seat and crossed Erlang's legs, sipping coffee while listening to the speech on the stage.

An old professor, who was over seventy years old, trembled to the blackboard, took off his hat and saluted, and began to write and draw on it.

"This time I'm talking about ordinary differential equations, where the letter x (or letters) is usually used to represent the independent variables in the ordinary differential equations, and y(x) is used to represent the unknown functions......

Before the board was finished, Hilbert couldn't read it anymore, put down his coffee, and said contemptuously: "Speeches, especially mathematical speeches, must be highly concise and clear, just like I am not interested in eating cake and your approach, just need to take your highlight 'raisins' and pick them out." My dear colleague, I beg your pardon for taking the liberty of writing so much, I'm afraid you don't know what a differential equation is, right?"

The old professor trembled with anger: "I respect your mathematical talent, but I can't be so arrogant as to say that I don't understand differential equations, I noted it in the first paragraph, if you can't see it clearly from a distance, I don't blame you, but it is unbearable to slander a gentleman."

Hilbert smiled, walked confidently to the front of the stage, pointed to one of the lines with a whip, and said: "My dear colleague, you must have been working at home day and night for a long time to come to this conclusion, but let me tell you that the Russian mathematician Lyapunov in his paper "General Problems of Stability of Motion" created a new direction in the study of nonlinear differential equations, and proposed a theory of stability of motion, which is completely used to solve the tendency of the initial perturbation of the solution of the equation without affecting the solution of the original equation."

Originally, I just wanted to wipe this line, but after wiping, I felt that the next line was not suitable, mathematics is like this, interlocking, and finally directly wiped all the board books behind, and then wrote it as a correct paper.

Hilbert patted the dust on his hands and said with a smile: "I'm sorry, I wiped all your achievements carelessly, but it's okay, anyway, I don't know how many years I've been eliminated, it doesn't matter."

When the old professor saw this, his eyes immediately went dark, and he almost fainted after being squeezed, but the assistant next to him was quick to help, and waved his hand dejectedly. Leaving the venue in embarrassment.

As a result, before he could take two steps, he tripped over an unwarranted barricade and fell to the ground.

Hilbert, the other protagonist of the incident, sat back in his chair, sipped his coffee again, and motioned for the next speaker to come on stage.

The colleague next to him was a little dissatisfied: "You shouldn't treat that old professor like this, he has made a lot of contributions to the development of our school's School of Mathematics earlier, for the sake of the original face, no matter what, we must save a little face for him." ….

Hibbert didn't care, and raised an eyebrow at the place where the old professor left: "It's not that I don't care about the face of my former colleague, but he really doesn't know what differential equations are, you see, isn't the direction he left on the way to the library, he must have gone to consult the papers."

The colleague was helpless, knowing that the other party was such a style of person, so he had to give up.

Seeing this battle, the young speaker who came on the stage next trembled a little, and bowed with a trembling voice.

"Hello teachers, first ....... First of all, I would like to state that the original author of this paper is not me, but the latest research on the "Theory of Class Domains" completed by Professor Tom Cheng of the mysterious Oriental country.

Despite the experience of the past, it is an honour to receive Hilbert's comments in person, even if it is just criticism, so young mathematicians from all over the world are willing to speak at the Göttingen Mathematics Club, despite the worst expectations.

Even so, the young man stumbled when he spoke, and even accidentally couldn't grasp the strength several times, and directly broke the chalk, and the people in the audience kept looking at Hilbert, their faces full of banter, hoping to give the young man a head-on blow.

"August, how about it, shall we bet on this poor young man."

"Bet on what?"

"Bet he was kicked down by Hilbert on the first line, I think before the thirtieth line, and the bet was 100 marks."

"Okay, then I'll bet ten lines ago, this little guy is not ready at all, and he is holding someone else's paper, which will only raise Hilbert's requirements, what a poor little sheep."

At this time, a young man directly took out a stack of marks and put them on the table.

"I want a thousand marks, and I bet that Mr. Hilbert will allow this student to finish the speech."

"What do you mean, Wiener, I know you have some talent for mathematics, but who can sit here and lack that talent? Young people, don't be too arrogant."

"That's what you're wrong, I'm not optimistic about this classmate, but Professor Tom Cheng behind him, proud Germans, it's time to lower your heads!"

After speaking, Wiener stopped having an invalid dispute with these people, and even the most famous genius in mathematics this year did not know, which showed that these people were half a pound and eight taels compared to the old professor just now.

Unexpectedly, Hilbert spent more time on coffee than he watched speeches at first, as they expected, but I don't know when his beloved coffee was put aside by him and directly changed to the first row of seats, and his face became solemn.

Seeing that the board was completed, he couldn't help but stand up, applauded, and said in a tone of disbelief: "The speech now is far worse than in the past. When I was younger, people were very particular about the art of public speaking, and speakers had a lot of ideas about what they wanted to say and how to do it well. Young people today don't do that, especially in Göttingen, where I think the worst speech in the world is probably done. This year has been even worse, I haven't heard a good talk at all, especially lately. However, there is an exception this afternoon......"....

"The fact that we can one day see the proof of the main ideal theorem means that the problem left over by the class domain theory for nearly thirty years has been solved, and all the conjectures about the nature of the class domain are correct, and in the face of absolute strength, there is no need for any bells and whistles!"

The latter process is much simpler, a group of people under the leadership of Hilbert began to analyze Cheng Nuo's research papers intensively, and the deeper they go, the more they can understand the meticulousness of their thinking, and even patch all the places that may cause controversy in advance, so that people can not find places that can be corrected.

Professor A sighed: "With the strength of Professor Tom Cheng's thesis, it is really incredible that my students who are not angry can see it and deduce it step by step, but if you think about it carefully, Kroneck's dream of youth is proved by himself, and he can still improve on the foundation, which is too much better than us in this one."

Professor B laughed, "But it's not without its shortcomings."

Professor C was curious: "Thinking so carefully that every step can be repeatedly scrutinized, what are the shortcomings?"

Professor B explained: "The biggest weakness is that he is not Germanic, and he has not even studied in Göttingen, and as far as I know, their government has just declared war on us, which is the biggest and most fatal flaw in the interests of the German Empire."

When Hilbert heard this, his face sank: "Science knows no borders, and in the life of nations, every country can only prosper if it is in harmony with its neighbors. The interests of the state require the establishment of a general order not only within each state, but also in relations between nations – and this is also true in scientific life."

However, the two countries were in the political background of the belligerent countries, and after the meeting, Hilbert not only publicly expressed his high recognition of the "National" magazine, but also did not hesitate to praise Professor Tom Cheng in the Far East, and directly locked him up

The conjecture of the class field theory was renamed "Hilbert-the theorem of the class field of programs", and in a semi-official capacity, on behalf of the European Göttingen School, Cheng Nuo's status was recognized.

Looking at the somewhat decadent professor gambler duo in front of him, Wiener excitedly took Mark from their hands, counted carefully, confirmed that the number was correct, and said with a smile: "Two gentlemen, if you are very interested in the study of the "Theory of Class Domains" after you go back, you will find that it is full of program theorems and program axioms, and the reason why I dare to make such a big bet is not a casual intuition, you Germans will eventually usher in the sunset."

The two were not convinced, saying that it was their mistake not to contact the professor for the paper, but there was no need to be so mocking, and besides, it was only a thousand marks, and they didn't see it at all, Professor Tom Cheng of the mysterious East hadn't shown off yet, where was Wiener's turn to be proud here.

Wiener took the money in his hand, patted it and said, "It's also a coincidence, who let this Professor Tom Cheng be my junior, and if you say bad things about your junior brother in front of me, you will naturally not give you a good face."

There are two flowers, one for each branch, and Princeton in the United States is happy and worried.

Fan Yinxi, the head of the mathematics department at Princeton, is that he really didn't misunderstand the person, this Tom Cheng has made such a great achievement quietly, and in his opinion, he has even simplified this subject to the extent that it cannot be simplified, and undergraduates can experience the charm of it, rather than like before, several professors gathered around to gnaw on papers, and they may not be able to get off the manuscript to the extent of secondary proof. ….

The worry is that this Tom Cheng has never replied to other questions except for a few common questions in the middle, and even the letter of appointment of a professor at Princeton University that he personally invited has been shelved, making him always think that it was Göttingen, Germany, who gave half of the beard, and later inquired in many ways to know that he had misunderstood.

It was not easy to put his mind at ease, but as a result, the new paper directly put aside their "Mathematical Yearbook" and published it in his own magazine, which inexplicably made Fan Yin feel like a little resentful woman.

"If you want to send a paper, come to us, not a single punctuation mark is changed, and the editor in charge of the whole audience automatically proofreads grammatical errors, and the manuscript fee is full throughout the process."

Wiblen raised his head and said with a smile, "Dean, as far as I know, although Tom Cheng did not accept our offer of offer, he also did not accept Harvard's offer, and we still have a lot of opportunities at Princeton."

Fan Yin took a pipe in his mouth, took a puff and held it in his hand: "For us, it is not necessarily a good thing, and with Tom Cheng's age, there may be greater academic achievements in the future, and at that time, our professorship at Princeton will not be so important."

Wiblen laughed and joked, "At that time, we will directly invite him to be the dean in the name of the Princeton School of Mathematics."

Unexpectedly, Fan Yin really thought that this idea was not bad, and nodded after pondering for a moment: "It's not impossible, as long as he is willing to come, and continues to maintain this review and continue to produce academic results, if he really becomes the dean of the School of Mathematics, we will also take advantage, and when the time comes, he will be the dean, and I will be the president, and it will not affect each other."

Wiblen was dumbfounded, and said in a sour tone, "If that's the case, the board of directors will have a hard time explaining it, after all, he can be the head of the first house of Princeton at such a young age."

Fan Yin said disdainfully: "Those guys will only talk about the benefits, if I personally tell them the value of Tom Cheng, I believe it will be even crazier than me, just ask if there is such a possibility to elevate the School of Mathematics to the level of the Göttingen School, it will mean that there will be more high-class people waving checks and coming to sponsor us, 'Franklin, the charm is not something that anyone can resist.'"

Wiblen originally wanted to continue arguing a few words, but in the end he suddenly felt that what he said was in vain, you must know that Tom Cheng's age is far from reaching the age of academic peak, and it is difficult to say what academic achievements he can continue to make in the future, but as long as he does not die halfway, then the place where he is is bound to slowly become a new mathematical center.

In this industry, the gap in intelligence between people is even greater than the gap between humans and dogs.

After a moment's hesitation, Veblen straightened his mind and asked, "But the courtyard

Chief, at the moment, Tom Cheng has not even accepted our professor's appointment letter, and I am afraid it will not be so easy to talk about other things later."

Fan Yincheng took it in mind: "This is simple, didn't Tom Cheng invite us to their annual scientific meeting at the end of the year, and then I will personally lead the team to invite him, so that he can see the sincerity of our Princeton with his own eyes."

In this way, similar plots also happened in England, France, Italy and other places, and people once again turned their attention to the poor soil of modern science in the East, and it was hard to imagine that a different kind of flower bloomed in the cracks of the stone, which mentioned the first annual meeting of the Academy of Sciences held at the end of 1917, which also began to attract the attention of the international academic community.

By the way, although the "National" magazine is not as good as his predecessors "Science" and "Nature", it has firmly occupied the second echelon, which is also a good result for the Academy of Sciences.

Sit and look at the two to fight for one, the days are still long, just take your time.
