I Just Want to Be a Salted Fish in Peace

　　In order for him to understand, Lin Xian expanded the formula in great detail, so that he filled a whole whiteboard.

　　After a while, he stopped the pen in his hand and smiled, "Do you understand?"

　　"understood!"

　　The graduate student nodded gratefully and sat down again contentedly.

　　Next, Lin Xian answered seven or eight questions one after another.

　　Compared with the first one, these problems are a lot more tricky, and they mainly involve ideas and mathematical tools used in solving problems.

　　After answering a question again, Lin Xian raised his hand and glanced at his watch. He found that there were still 3 minutes before the end of the report, so he smiled and said, "The last question is this teacher!"

　　The person named by Lin Xian was the white-haired old man sitting next to Professor Zhou Haizhong in the first row.

　　The old man took the microphone and said unhurriedly, "You mentioned the big sieve method before, why didn't you use the big sieve method in the formula in the third row on page [-]?"

　　Hearing this question, Lin Xian smiled slightly and blurted out, "Of course it is..."

　　Before he finished speaking, Lin Xian couldn't help but froze in place.

　　I saw him frown slightly, and said thoughtfully: "Your question is a bit interesting!"

　　Have... a bit of fun?

　　Boy, this is so beautiful.

　　The bigwigs in the audience all looked at the white-haired old man in the front row with slightly strange eyes.

　　Even the white-haired old man himself was a little surprised at this moment.

　　how many years...

　　It has been almost fifty years since I graduated from my doctorate, and no one has ever said to myself, 'Your question is interesting'.

　　Today, not only did someone say it, but the other party was still a freshman.

　　This made him feel as if he had returned to a certain afternoon in the late autumn, more than fifty years ago. After reading his graduation thesis, his teacher Chen Shingshen said with a smile, "It's interesting!"

　　This kind of time and space interlaced memories made him a little trance and miss for a while.

　　After returning to his senses, the white-haired old man asked with great interest, "What kind of interesting method?"

　　Lin Xian did not answer, but turned around and erased all the content on the whiteboard, then picked up the marker and quickly wrote down a line of formulas.

　　Everyone in the audience frowned slightly at this moment, a little inexplicable.

　　Because what Lin Xian wrote was really the formula in the third line of the sixth page of his own thesis.

　　However, he did not use his own method to solve the problem, but adopted the large sieve method.

　　Lines of complicated and cumbersome formulas, like flowing water, kept appearing on the whiteboard.

　　The crowd under the stage became more and more confused.

　　At this moment, the white-haired old man's eyes suddenly lit up, and he slammed his thigh, and said with a pleasant expression: "Good boy, I want this student!"

　　Zhou Haizhong on the side was also confused at first, but after looking at it, he quickly understood.

　　Twin prime conjecture!

　　In just a few seconds, I thought of using the big sieve method as an entry point to try to prove the twin prime conjecture.

　　And based on the current progress, there is no problem with the logic!

　　Dear, are young people nowadays so fierce?

　　hiss!

　　Zhou Haizhong took a deep breath and couldn't help touching his shiny bald head. He couldn't help feeling that the back waves of the Yangtze River pushed the front waves, and the front waves died on the beach. .

Chapter 491

　　Gradually, many people in the audience reacted and understood what Lin Xian was doing.

　　For a while, there was a burst of whispers.

　　Principal Wang Kai was a little stunned at the moment. After all, he came from a liberal arts background. There may be no problem with undergraduate mathematics, but when it comes to a higher level, he is completely dumbfounded.

　　Glancing at Zhang Jundong next to him, Wang Kai couldn't help but ask, but the whispers in the auditorium filled him with curiosity and worry.

　　Originally, the whole report will go well - smoothly.

　　Seeing that there is one last question left, it can end successfully, but such a change suddenly occurred.

　　Although I don't know when this change is good or bad, it still makes Wang Kai feel a little uneasy.

　　After hesitating for a moment, he finally lowered his voice and asked, "Old Zhang, what is Xiao Lin doing?"

　　Zhang Jundong frowned and replied in an uncertain tone, "He seems to be trying to prove the twin prime conjecture."

　　He was indeed a little unsure, because Lin Xian's entry point was very strange...it could even be described as strange.

　　At the beginning, I was still using the big sieve method to prove my formula in the third row of page [-].

　　However, after witnessing the evidence, he suddenly turned a big turn, which seemed extremely rude, but in fact it was substituted into the twin prime number conjecture very cleverly.

　　And from the current point of view, there is no problem with Lin Xian's proof logic.

　　To be honest, this bend was too big and too fast, and almost missed Zhang Jundong's waist.

　　It's so showy!

　　Hearing this, Wang Kai was stunned.

　　Twin prime conjecture?

　　Isn't this TM...a report meeting that proves Zhou's guess?

　　After regaining his senses, Wang Kai said anxiously, "Hey, classmate Xiaolin, isn't this a mess!"

　　"Recklessly?"

　　Zhang Jundong shook his head, took over the words and said, "No. So far, there is nothing wrong with his proof logic!"

　　Ok?

　　Wang Kai was stunned again.

　　What he meant was that he just wanted to bring this report to a beautiful end.

　　That's why I said that Lin Xian was in a mess, but now, listening to Zhang Jundong's meaning, Lin Xian seems very hopeful to prove the twin prime conjecture.

　　"hiss!"

　　Thinking of this, Wang Kai couldn't help taking a breath, and a look of ecstasy appeared on his face.

　　If Lin Xian proves another mathematical conjecture at his report meeting, then the effect...

　　Suppressing the ecstasy in his heart, Wang Kai said sternly, "Old Zhang, do you think he has hope?"

　　"Hard to say!"

　　Zhang Jundong frowned and said: "Some time ago, Professor Zhang Yitang took a critical step in reducing the C value from infinity to 7000 million. But from 7000 million to 2, it is still a difficult problem."

　　Going from infinity to 7000 million is a huge improvement.

　　Professor Zhang Yitang can be said to have proved a weakened form of the twin prime conjecture.

　　Because 7000 million is still very far away from the real limit: 2.

　　It's like climbing over a big mountain, only to find that behind the mountain is a higher and steeper mountain.

　　In addition, Professor Zhang Yitang still used traditional mathematical tools when proving, and did not create new tools.

　　This puts him in a bottleneck in the next proof from 7000 million to 2.

　　Not only Wang Kai, but even the white-haired old man seemed a little excited at this moment.

　　If Lin Xian really proves the twin prime conjecture, even if no new mathematical tools are created during the proof process, then the next Fields Medal must be a sure thing.

　　Compared with Zhou's guess, the proof of the twin prime number conjecture will be more meaningful.

　　Once the twin prime conjecture is proved, it will play a huge role in proving Goldbach's conjecture.

　　Secondly, it will also make great contributions to applied mathematics, such as encryption, cryptography and so on.

　　Zhou's conjecture plus the twin prime conjecture, if this doesn't win the Fields Medal, it can only mean that the Mathematician Conference has also been eroded by geopolitics.

　　That's why the white-haired old man looks so excited.

　　At this time, Zhao Shitong was still confused.

　　In fact, from the beginning of the report to the present, she has basically been in a state of confusion.

　　Seeing the frowning and sometimes excited expression of the old professor beside her, she couldn't help but ask, "Uh...Professor Li, what is he doing?"

　　Being disturbed, Professor Li looked a little unhappy, turned around and glanced at her, and frowned: "I don't understand this? How did you get in?"

　　Zhao Shitong: ? ? ?

　　This TM... Didn't you bring me in?

　　Besides, as a psychology graduate student, I can't understand mathematics of this level, isn't it normal?

　　Hi, so angry!

　　Zhao Shitong pouted and stared at Lin Xian on the stage with resentment in his eyes.

　　However, Zhao Shitong almost believed it in Lin Xian's words on his cruise ship last time that he used mathematics to calculate their trump cards.
