Chapter 257 Is this guy cheating?
The office is quiet.
Academician Yang has experienced things for most of his life, and he can basically remain calm, but at this time, his face still showed surprise subconsciously, and it took him a long time to react, "Did you make it?"
< br>“Yes.”
“Have you solved all three questions?”
Xu Qingzhou nodded again and handed over the manuscript paper.
These three questions are not difficult. You can basically know the answers in your mind at a glance. The reason why it takes 20 minutes is just the writing process.
Academician Yang stared at the manuscript paper and read it carefully.
Zhang Changqing looked strange and glanced at the time. Oh, it was only 20 minutes. This junior brother Xu is not fooling people, right?
But.
The teacher's expression is very serious.
Academician Yang’s eyes quickly swept across the manuscript paper.
The first question was answered very well.
Second question, no problem.
Question 3.
After a while, Academician Yang exhaled and said slowly: "That's all right."
"It could have been faster, but the writing process wasted some time."
"."
The corner of Zhang Changqing's mouth twitched. Can a person really be so incredible, so good at mathematics, so good at quantum physics, and so good at particle physics? !
Is this guy cheating?
He also tried these three questions at the beginning and it took him almost 30 minutes.
But he now has a PhD and will graduate soon.
Academician Yang looked at the last question again and said in amazement: "Not only are they all correct, but the answers are also brilliant. Xiao Xu, it seems that you have really worked hard in the field of particle physics. "
"It's just interest, not very deep." Xu Qingzhou smiled.
Zhang Changqing's expression was even more complicated. Although this junior brother spoke sincerely, why did he always feel like he was showing off.
Academician Yang smiled softly, handed Xu Qingzhou a USB flash drive, and said: "Here are all experimental materials about CMS. You go back and take a closer look, but I can tell you first."
"This time it is mainly to explore the Higgs particle that was definitely discovered in 2013, including its mass, spin, coupling strength, etc. It started on August 10. The process went smoothly and can be completed in about one month."
Xu Qingzhou nodded slightly and listened carefully.
The Higgs particle, also known as the Higgs boson, is an important particle predicted by the Standard Model of particle physics. It is also an important research content in the field of physics for a long time.
The British scientist Peter Higgs proposed the existence of the Higgs field in 1964, and further predicted the existence of the Higgs particle. Unfortunately, it was almost 50 years ago, in 2013, that the Higgs field was discovered at the LHC ( Found at the Large Hadron Collider.
"I don't care about quantum mechanics and field theory. This month, I suggest you read "Introduction to Particle Physics" and "Particle Detector and Data Acquisition", especially the latter."
< br>"Also, your documents for going abroad are being processed, but you need to confirm your visa. Don't find out it's expired just when you are about to leave."
At the end, Academician Yang reminded with a smile.
"Okay, thank you, professor." Xu Qingzhou nodded and thanked.
After coming out of the Institute of High Energy Physics, Xu Qingzhou went straight home. The library was full during this time, and he and Song Yao were both reading at home.
On the last day of June, Johns Hopkins University announced that the proof was not valid because it could not solve the "horizontal" problem of the even distribution of prime numbers in arithmetic series.
[∑q≤xmax(qa), text{eff}}}{\varepsepsilon\frac]
Although he has not seen the text of the paper, perhaps Qingzhou basically understands what the problem is. The estimation used by Professor Stewart is also the GPY sieve method, because Zhang Yitang's paper on the twin prime conjecture also encountered this problem.
In this formula, heta is a positive number, \phi is the Euler function, and A is an arbitrarily large positive number.
This formula is true when heta is small, and when heta=1/2, this formula is true. And when heta reaches 1, this formula is wrong.
Zhang Yitang solved this problem using the decomposition method. In other words, Professor Stewart has not found a suitable or correct method.
Xu Qingzhou just smiled lightly at this news. This kind of thing is normal in academia. A proof usually consists of a series of key points, which are based on other key points. , if there is a problem with one point, it is likely to mean that the entire paper is wrong.
So he couldn't talk about gloating about his misfortune, but concentrated on his own deduction.
His side is going pretty smoothly. The number of calculation papers and information on the table is increasing day by day, and there are already more than a hundred sheets.
In the early morning of July 1st, Song Yao was reviewing at home, while Xu Qingzhou took the subway to the Quantum Institute again.
"Junior brother."
At the entrance of the research institute, Deng Ziyi was eating steamed buns. When she saw Xu Qingzhou, she waved hello.
"Good morning." Xu Qingzhou smiled. I don't know why, but I always felt that this senior sister was rounder than when they first met.
Deng Ziyi is helpless. In the past few months, she has gained 8 pounds. She goes to eat when she is stressed and has to eat again after finishing her work in the middle of the night.
"Junior brother, I remember you were responsible for the decoding algorithm. Did it go well?"
"It went well." Xu Qingzhou nodded. He had studied this thing countless times before and was very proficient, so he didn't waste much time. .
Deng Ziyi praised: "Awesome, he is indeed the 'strongest intern' since our institute was established."
"It just helped me a little bit."
< br>"Junior, I think you are in Versailles."
"Is this obvious?"
"."
"Xiao Xu."
Professor Chang took the hard drive handed over by Xu Qingzhou and smiled, "Sit down first and wait for someone. Qi started reviewing the data. I heard from Lao Ji that the Institute of Physics is planning to let you participate in the CMS experiment in Switzerland next month? "
Xu Qingzhou replied: "Well, you want me to go out and see more of the world. .”
Professor Chang nodded slightly and sighed with emotion. They brought Xu Qingzhou here originally with the intention of giving the young people a good exercise, but it turned out that he didn't need it at all.
Deng Ziyi: I am tired of saying the word envy.
After saying hello to acquaintances and seeing that there was still time, Xu Qingzhou took out the information on Polignac's guess from his bag and looked at it slowly.
The meeting begins.
Everyone reported the situation on their side, and finally handed it over to Senior Brother Qi and the others, with Xu Qingzhou helping with calculations.
"First of all, let me announce that the experiment we originally planned to conduct in November will be completed in September. At the same time, the launch time of the satellite will also be adjusted, five months in advance."
"In other words, We can set off fireworks for the people of the whole country in advance."
Xu Qingzhou was not surprised. The development of the Mozi satellite has already reached the final stage, and the follow-up is basically actual testing, not to mention that his article is almost 100 pages long. The paper still has something to offer.
"Of course, Xiao Xu has made great contributions to being able to launch the satellite ahead of schedule, and helped us solve many key problems."
Applause broke out in the conference room.
Xu Qingzhou smiled modestly and added: "I just made a negligible contribution, and the current success is the result of everyone's joint efforts."
This is also true. His experience certainly did not come out of thin air. Rather, we should first learn from the experiences of our ancestors, and then practice ourselves and gain new experiences.
In other words, everyone here, including Deng Ziyi, is considered his "master".
The model, system design, etc. have all been calculated. The next step is to continuously conduct simulation experiments to correct the equipment and the entire system.
Thus, Xu Qingzhou’s work here has come to an end for the time being.
