"Hiss-It seems that if you didn't call me this, I would have thought I would have hallucinated."
Seeing Chen Mo writing while explaining, many people in the lecture hall showed a look of surprise. After a sparse sound came from the lecture hall, they returned to quiet again.
Everyone present looked up at the young people who explained to them slowly. They didn't expect that Chen Mo would tell them in this way when he solved the problem.
this……
Everyone didn't know what to say for a moment.
Just like a teacher giving questions to students, you must read the knowledge in your mind in advance, commonly known as preparing lessons. Only in this way can you express your thoughts and logic fluently when telling, which is better than doing your own questions directly.
It's much more difficult.
Everyone looked at the young man in surprise, and no one expected that the Youth Association would explain to them while solving problems.
This is how confident you have in your own logical thinking, but how much language logic control ability is.
It would be fine if the thinking was smooth all the time, but what if it got stuck in the middle?
He can't be like a teacher preparing lessons or telling previous reports. He has already sorted out his ideas and is ready.
joke,
How is that possible?
Everyone didn't know what they thought of, so they glanced at the piece. Before they could wipe it, Chen Mo drew all kinds of characters.
Maybe?
Lu Wenxuan and other professors sitting in the front row subconsciously glanced at the colorful blackboard. The thought that made people's scalp numb for a moment was floating in their minds.
This is impossible...it's crazy.
Lu Wenxuan held the pen's hand and seemed to be breaking the signature pen in his hand. It was really incredible that the thought in his mind was really... no, it could not be true.
Lu Wenxuan suppressed the feeling of discomfort and uneasiness in his heart, and tried to stabilize the expression on his face, and even a sarcastic smile appeared on the corner of his mouth.
Moreover, it seemed as if he could solve it.
The professors around also reacted. Whether Chen Mo had just calculated it himself, it was the focus now, or the final result was the focus.
In the end, it was not solved, and nothing was meaningless.
Chen Mo didn't care about the storm below, whether it was given expectations, speculation, or maliciousness. His thin back stood under the huge blackboard, holding his hands with chalk, slowly writing.
"One of the expressions depends only on prime numbers. Expressions in positive integer form are the same as those in prime form, but the former is easier to use because we only know what all positive integers are, but we don't know what all prime numbers are like
. But the two expressions are equivalent, we can use one instead of the other... The zeta function is very useful, but we all know that it is not easy to use it well. Using the Bernoulli number, we can only calculate it
When the coefficient is even, the zeta function value... odd function value is difficult to obtain...so let's look at the most intuitive image representation..."
"Although we cannot find its exact value, we can calculate an approximation of "good enough". We do not calculate the sum of infinite terms, but only approximate the accurate result by calculating the sum of finite terms. If there are only 3 terms, we will get ζ
(3)=1.361111111, and the results of the first 3 items are not very close. Taking the first 10 items will be more accurate, and the error will be reduced to 5.8%, and so on. If the first 1 billion items are added up, you will eventually get ζ (100,000,000)
=1.64493405783457, this number is close to the exact answer."
Every stroke that Chen Mo puts on chalk is very light, but even when written in English, the font has a flowing but vigorous and powerful feeling. The formulas and data that are neat enough to make mistakes are listed on the blackboard, which is clear
Give everyone a clear idea and proof process. Even if you don’t understand mathematics, you can use language reading to understand the proof thinking process.
Of course, this kind of algebraic proof is mainly based on the thirty-forty percent "calculation", and calculation is the most important.
While he was writing, the staff beside him drew a new blackboard for him to use as soon as he finished writing the last blackboard. Chen Mo drew a new blackboard on the latest blackboard that the staff had wiped.
Image of the zeta function value of each number between sub-10 and 10.
Below this picture, using the data I had calculated in front of everyone before, and under the gaze of everyone, two three-dimensional images of the zeta function were drawn with bare hands. It was okay that the professors who followed closely the calculations came to the end, but after Chen Mo finished drawing it
After a moment of stunned silence, he was quickly attracted by the data and began to calculate rigorously. However, those students who are not majoring in mathematics, or who have only listened to their ideas and gave up on large-scale calculations, were stunned at the image and stared at it for a long time.
.
"Damn!"
"Fake!!"
“…”
...
Many people in the lecture hall were held in for a long time but couldn't help it. They shouted several national curses, expressing their feelings of countless grass and mud horses running past and lying in a big trough.
You're too much!
You calculate it and we recognize it, but what happened to you draw this three-dimensional demonstration diagram? Do you think you are a computer? You even draw this thing when you talk about a question... Although there are many opportunities for drawing in the academic community,
I have seen circles drawn with bare hands and data analysis diagrams drawn with bare hands, but isn't your three-dimensional demonstration image of the bare hands showing the function too much?
Do you think you are a printer? Or are you just a robot?
Look at this picture, there are all perspectives. This small perspective line is drawn. There are two perspectives and three perspectives? The most outrageous thing is that all the data can correspond one by one on the coordinate axis.
superior……
Your hands are not your hands, right? You have swallowed your computer, otherwise why would there be no errors or errors at all? Don’t you shake your hands?!
Can you explain why, one of you, a physical researcher, stepped into the field of mathematics, and it was so outrageous that it split into the Milky Way and the Art field? The last one did it like this, it seemed like half a century ago
Leonardo da Vinci, drawing human anatomy pictures with freehand hands and so on.
Although they have drawn a few anatomical pictures with text explanations on the small notebooks, they are also very abnormal. But they have not done this casually in such a lecture.
Do you know that the visual impact is very strong? Hello!?!
Leonardo da Vinci achieved the level of drawing casually through a large number of anatomical corpses and drawing exercises. If you paint like this, is it because you are secretly drawing such 3D demonstration pictures in private? Who would do this?
A psychopath!
Of course, they had a big trough in their hearts, and they couldn't say it at this time. They could only look at Chen Mo with a casual attitude of being used to it, as if they were just drawing a circle on the blackboard. Everyone felt that they were about to be suffocated to death.
It's right, and the fist is hard.
If Chen Mo knew, he would definitely say that he was innocent. He was not a cross-border person. He was a serious art student. This is basic skill. Moreover, the teacher asked them to draw architectural drawings some time ago. He would draw pictures whenever he had time.
He copied hundreds or eighty pictures and drew hundreds or eighty pictures. He may not be able to draw more complex space pictures, but the three-dimensional demonstration pictures are really like eating and drinking water for him.
He was so used to drawing architectural drawings that when he saw very flat and vertical lines and three-dimensional spatial models, he felt itchy. When he saw the data in his mind, he subconsciously associated the demonstration diagram, and he subconsciously drew it out.
Thinking about explaining the data he wants to talk about, the corresponding rules and trends, he drew it...
Well, so it seems that anyone can make mistakes.
But unfortunately, Chen Mo didn't know. Maybe he was talking too much today. He coughed twice by the dust choked, left his lips, raised his hand and pointed at the image, and continued to talk.
As he analyses his speech bit by bit, many mathematicians present were getting brighter and brighter.
"When the input value is positive, the output value drops at infinity and then slowly approaches 1; the function image on the left fluctuates back and forth on the x-axis, it regularly passes through the horizontal axis, and the function value of the intersection point is 0,
These points are called trivial zeros. When the input value is negative even, the trivial zeros will appear as scheduled, because one of every two consecutive Bernoulli numbers is 0... You can see that the trivial zeros are negative on the x-axis
In the direction, you can also see some unexpected zero points, which are arranged on a straight line. This is actually a logarithmic image of the zeta function. This straight line is perpendicular to the original number axis. But these zero points are not ordinary zero points..."
The young man's voice was hoarse, but it was filled with the clearness and vitality of the young man, just like the rising stars at night.
It was clearly such a large area of blackboard, and the young man against the backdrop was even a little thin and small. But it was such a small body that used small chalk to cover the entire blackboard again and again. Once, the blackboard became
It became a vast white piece, and it turned black again, and then turned white again.
It's like a silent painting of turning pages in black and white tones.
The camera recorded it, so shocking that words cannot be expressed.
As the young man wrote little by little, the staff wiped it again and again, not knowing how many words were covered and repeated.
The sunlight outside the window, which was originally at noon, gradually fades away. The sun slowly sets from the west. When the remaining collides with the horizon, it is as bright as fireworks, and the orange tones collide with the brilliant golden yellow, which contrasts with the blue sky and
The light gray clouds all seem to be from the inside out, emitting the most gorgeous brilliance.
The sun sets in the west and night comes. The street lights outside the window are on, shining on the trees and scattered shadows on the ground. The indoor lights that were not visible during the day are now due to the arrival of night.
It splashed out, and the window ridges of the stairs of the classroom were covered with the yellow light of incandescent lamps, and the window ridges also had a slightly tilted but very orderly shadow.
It was three hours. Chen Mo really kept solving problems since his report meeting at three o'clock. He talked about it now, but he didn't expect that he would talk for such a long time. He took the little lesson in his mind.
With the help of the blackboard, I completed the jumping thinking concept in my mind, but I didn’t expect that so many would be written down one by one.
But it's coming to an end.
When Chen Mo was on the last piece, he had been wiping it through many times by him, he pressed the last dot heavily.
With a gentle sentence "...this can be proved."
The scene fell into a long and long silence.
Chen Mo had never said so many things. After five or six hours of continuous speech, his voice was already a bit chopped at the end. But the hoarse and extremely light voice as if a willow leaves fell into the floating water was among the crowd.
The ancient bell rang out in my heart like a "dong!"
It was as if the galaxies were falling down one by one, and the eyes were like the galaxies were flowing, all of which were shiny and shiny, and everyone had a trance-indecent feeling.
real……
Really, it was solved.
It's really solved...
Chen Mo also had a very happy smile on his eyes. Although his right arm was sore, an indescribable sense of happiness appeared in his heart, and he took a deep breath...
"Ahem...ahhhhhhhhhhhhhhhh!"
A violent coughing sound.
Chen Mo almost got choked and was shocked.
This place is now occupied by biological and chemical weapons. Chen Mo lowered his head and glanced at the ground. The place where he was standing was already covered with large white dust. He just solved the problem and did not find it. Only then did he pay attention.
It was not too panic when I got to myself. The black suit I asked by the teacher to change into was still borrowed from my senior. It was already covered with large pieces of dust. With a beat, Wuhu~ It was foggy! Chen Mo coughed again
.
Help, he thinks he will have tonsils tomorrow, help!
After being really troubled, Chen Mo's thoughts also moved from the joy of solving the problem. He now wanted to rush to the hotel to rinse himself, and then drink a bag of isatis roots before the cold came.
, block the road first. As long as he drinks fast enough, he will not be able to catch up with him!
He rarely gets sick, but it is difficult to heal once heals when he is sick. It is different from his outrageous healing ability. He never stops from getting a cold. When he thinks of the cold he caught when he was a child, Old Chen was in a hurry and wanted to wrap him up.
A five or six-layer large quilt, he was not blocked by his nose blockage, and almost suffocated to death by the quilt, and his scalp became numb. Of course, it was not just this, he had a cold, not only Lao Chen, but also a series of calls if he knew about it.
When they call, they can either get to a Tang Monk.
He felt that he had been sick so little since he was a child, and most of the contributions to his parents.
Absolutely, you must not get sick! He must not catch a cold!!
"Okay, up to this point, everyone's proof process is here. I've tried to write it in detail every step. If anyone here has objections to the proof process or has objections to the process data,
Welcome to make corrections.”
