Chapter 257 Is this guy cheating?
The office fell silent.
Academician Yang had been through a lot in his life, so he was basically able to remain calm. However, he still subconsciously showed surprise on his face at this moment, and it took him a long time to react, "Did you do it?"
"Ah."
"Have you solved all three questions?"
Xu Qingzhou nodded again and handed over the manuscript.
These three questions are not difficult. You can basically know the answers in your mind after just one look. The reason why it takes 20 minutes is just for the writing process.
Academician Yang stared at the manuscript and read it carefully.
Zhang Changqing had a strange look on his face and glanced at the time. Wow, it was only 20 minutes. Could this Junior Brother Xu be fooling him?
but.
The teacher's expression is very serious.
Academician Yang quickly scanned the manuscript paper.
The first question was answered very well.
Question two, no problem.
Question 3.
After a while, Academician Yang exhaled and said slowly, "All correct."
"It could have been faster, but the writing process wasted some time."
"."
Zhang Changqing's mouth twitched. Could a person really be so amazing? Mathematics, quantum physics, and particle physics?!
Is this guy cheating?
He also tried these three questions at the beginning, which took him about 30 minutes.
But he is now in his third year of doctoral studies and will graduate soon.
Academician Yang looked at the last question again and said in amazement, "Not only are all the answers correct, but the answers are also very brilliant, Xiao Xu. It seems that you have really worked hard in the field of particle physics."
"It's just an interest, I didn't go into it in depth." Xu Qingzhou smiled.
Zhang Changqing's expression became even more complicated. Although this junior brother spoke sincerely, why did he always feel that he was pretending?
Academician Yang smiled gently, handed Xu Qingzhou a USB drive, and said, "These are all experimental materials about CMS. You can go back and take a good look at them, but I can tell you first."
"This time, we are mainly exploring the Higgs particle that was confirmed to be discovered in 2013, including its mass, spin, coupling strength, etc. We set out on August 8th. The process is going smoothly and it will probably be completed in 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 and has long been an important research topic in the field of physics.
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 not discovered until 50, almost 2013 years later, in the LHC (Large Hadron Collider).
"I'm not going to bother you with the content on quantum mechanics and field theory. This month, I suggest you read Introduction to Particle Physics and Particle Detectors and Data Acquisition, especially the latter."
"Also, your documents for going abroad are being processed. 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 in thanks.
After coming out of the Institute of High Energy Physics, Xu Qingzhou went straight home. The library was full during this period, so he and Song Yao were both reading at home.
On the last day of June, Johns Hopkins University announced that the proof was invalid because they could not solve the "horizontal" problem of the even distribution of prime numbers in an arithmetic series.
【∑q≤xmax(qa)，text{eff}}}{\varepsepsilon \frac】
Although he did not see the main text of the paper, Xu Qingzhou basically understood where the problem lay. Professor Stewart probably used the GPY sieve method, because Zhang Yitang's paper on the twin prime conjecture also encountered this problem.
In this formula, where heta is a positive number, \phi is the Euler function, and A is an arbitrarily large positive number.
When heta is small, this formula is valid, and when heta=1/2, this formula is valid. But when heta reaches 1, this formula is wrong.
Zhang Yitang solved this problem by using the decomposition method. In other words, Professor Stewart did not find a suitable or correct method.
Xu Qingzhou just smiled faintly at the news. This kind of thing is very normal in the academic world. A proof is usually composed of a series of key points, which are built on other key points. If there is a problem with one point, it is very likely that the entire paper is wrong.
So it can't be said that he was gloating, but instead he was concentrating on his own deductions.
Things were going well for him. The calculation papers and materials on his desk kept increasing, now totaling more than a hundred sheets.
Early in the morning on July 7st, Song Yao was reviewing at home while Xu Qingzhou took the subway to the Quantum Research Institute again.
"Junior brother."
At the gate of the research institute, Deng Ziyi was eating a bun. When she saw Xu Qingzhou, she waved and greeted him.
"Good morning." Xu Qingzhou smiled. He didn't know why, but he always felt that this senior sister had become more plump than when they first met.
Deng Ziyi is helpless. She has gained 8 kilograms in the past few months. She has to eat when she is stressed and eat again when she is done with work in the middle of the night.
"Junior brother, I remember you were in charge of decoding the algorithm, is it going well?"
"It went quite smoothly." Xu Qingzhou nodded. He had studied this thing countless times before and was very proficient at it, so he didn't waste much time.
Deng Ziyi praised: "Amazing, he is worthy of being the 'best intern' since the establishment of our institute."
“It just helped a little bit.”
"Junior, I think you are in Versailles."
"Is this obvious?"
"."
"Xiao Xu."
Professor Chang took the hard drive from Xu Qingzhou and smiled, "Sit down first, and we'll start comparing the data once everyone is gathered. I heard from Old Ji that the Physics Department is planning to let you participate in the CMS experiment in Switzerland next month?"
Xu Qingzhou replied: "Yes, he wants me to go out and see more of the world."
Professor Chang nodded slightly, looking emotional. They had brought Xu Qingzhou here before, thinking of giving the young man some good training, but it turned out that he didn't need him at all.
Deng Ziyi: I’m tired of saying the word “envy”.
After greeting his acquaintances, seeing that there was still time, Xu Qingzhou took out the information on Polignac's conjecture from his bag and read it slowly.
The meeting begins.
Everyone reported their own situation and finally handed it over to Senior Brother Qi and the others, with Xu Qingzhou helping with the calculations.
"First of all, I have a piece of news to announce. The experiment we originally planned to conduct in November can be completed in September. At the same time, the launch time of the satellite has also been adjusted to five months ahead of schedule."
"That is to say, we can set off fireworks for the whole nation in advance."
Xu Qingzhou was not surprised. The development of the Mozi satellite had already reached the final stage, and the follow-up work was basically actual testing. What's more, his nearly 100-page paper did have some substance.
"Of course, Xiao Xu made a great contribution to the early launch of the satellite, helping us solve many key problems."
Applause broke out in the conference room.
Xu Qingzhou smiled modestly and added: "I just made a small contribution. 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. Instead, he first learned from the experience of his predecessors and then trained himself to gain new experience.
In other words, everyone present, including Deng Ziyi, considers him "master".
The models, system designs, etc. have all been calculated, and the next step is to conduct continuous simulation experiments to correct the equipment and the entire system.
So, Xu Qingzhou's work here came to a temporary end.
