Chapter 107

Just the morning after Xu Qingzhou replied to the editorial department's email, he received an email from Professor Steven.

First, he expressed admiration for Xu Qingzhou, thanked Xu Qingzhou for bringing him new ideas, and hoped Xu Qingzhou would agree to cite the expressions in Xu Qingzhou's paper in his subsequent published articles.

And invited Xu Qingzhou to study abroad at Princeton.

Xu Qingzhou politely declined the invitation to study abroad, saying he would consider it when studying for his doctorate later.

As for citing the paper, there was no problem.

Everything was as usual. Kong Xianbo accepted an interview, published on the official website. Zhai Ziqiang was stimulated, and except for resting at night, he basically couldn't be seen. Xu Zhengyang said he wanted to be a "anti-rolling" expert... After everyone got busy, time seemed to be pressed on the fast-forward key, and two weeks passed just like that.

Xu Qingzhou had been working on the Cramér conjecture. During this period, he had been trying to apply analytic number theory, first using mathematical tools such as series and integrals to analyze the distribution laws of prime numbers.

The prime number theorem, the z-function, and other asymptotic formulas for prime distribution, such as using the logarithmic integral li(x) to represent the asymptotic value of π(x), and using the Chebyshev inequality to describe the upper and lower bounds of π(x) in the prime number theorem.

Just building the primary mathematical model above, his computer was already a bit hard to handle when calculating.

Xu Qingzhou thought for a while and said: "Forgive my bluntness, among the conditions you mentioned last time, only the guidance of an academician is a bit attractive, but... can't I study for a master's degree at Jingda?"

"You're just leaving like this?" Wu Tianyu had a look of "you are too heartless."

Xu Qingzhou retreated a bit without a trace, pulling away the distance, and reminded: "Sister Tianyu, you are too close."

Due to the long experimental cycle, Wang Wei, Wu Tianyu, and Hong Yayu took turns on duty, each staring for 8 hours, while Xu Qingzhou was responsible for data processing and analysis.

Don't look at the experiment as being very high-end, but doing it for real was quite boring and dull.

But progress was slow.

"Xu Xu Shidi." Wu Tianyu paused the TV series on the screen and greeted enthusiastically. "Sister Tianyu." Xu Qingzhou smiled and copied data in front of another computer.

After the progress was not difficult, he temporarily put down this method and turned to follow another path in the initial design plan, through different sieving methods, the Selberg sieve method, the Chinese Remainder Theorem sieve method, etc., to first accurately understand the distribution of prime numbers.

The operation room was not big, only five or six square meters. Besides the console, it could only hold two computers.

Xu Qingzhou stopped his steps, seemingly thinking of something, and stood in front of Wu Tianyu's computer, "Sister Tianyu is watching 'The Journey of Flower'?"

According to Wang Wei, just in the year of doing the experiment, he himself had watched more than 100 movies.

After two weeks of struggle, a primary mathematical model had already been established.

Wu Tianyu propped her chin, her face straightened, and asked: "Xu Xu Shidi, are you really not considering my proposal last time?"

The isolation room was a modified MRI device. Unlike the ones in hospitals, part of the shell of this device was removed, revealing complex parts, various lines were intricate, but it looked like it had a kind of mechanical charm.

Xu Qingzhou didn't answer her, but asked: "Which character do you like the most?"

At this time, Xu Qingzhou copied the data, got up, and packed his things to leave, "Sister Tianyu, goodbye."

!.

Everything was light and familiar.

The initial project plan was less than 5000 words, but every part of it was extremely difficult. Before Wu Tianyu could react, Xu Qingzhou slipped away, pushed the door open with a happy mood, and left, leaving Wu Tianyu alone gnashing her teeth.

After the MRI equipment was installed, Wu Tianyu became a member of the project team, responsible for daily equipment inspection and also responsible for part of the experimental work.

October 22, Wednesday.

Xu Qingzhou directly found an empty classroom and started analyzing yesterday's data. First, he used filtering technology to remove noise and extract signals in a specific frequency range, then converted the MRI signal from the time domain to the frequency domain for analysis until finally bringing it into the mathematical model to simulate the data.

After this period of contact, he had already understood that this woman was just greedy for his body!

She looked at the data while saying as if nothing had happened: "This is yesterday's data, hmm... the data fluctuation is relatively large... Xu Xu Shidi, where do you think the problem is?"

Xu Qingzhou nodded, turned to prepare to leave, and at the moment of opening the door, turned to look at Wu Tianyu: "Unfortunately, Tang Bao and Luo Shiyi both died, both died very miserably."

In a few days, after perfecting the model, he could go find Professor Gu to see how to apply for the college's computer room to conduct large-scale data screening.

When Xu Qingzhou went in, Wu Tianyu was sitting in front of the computer, binge-watching the fairy drama "The Journey of Flower" that was just released this year.

For example, in the link of niobium-titanium alloy sample testing, the resistivity test, one sample test was 12 hours.

"Xu Xu Shidi, has anyone ever told you that you will be lonely for the rest of your life like this." Wu Tianyu said quietly. Clearly, the last condition was the most attractive, okay.

After class, Xu Qingzhou went to the MRI lab to get the data.

"Right, Xu Xu Shidi, are you watching too?" Wu Tianyu seemed to have found a soulmate and invited: "Do you want to watch together?"

7 days ago, the MRI equipment was installed, and Zhao Shengwen led the project team into the third stage.

Xu Qingzhou put on his work clothes and entered the operation room.

Currently, Kyoto is considered to have completely entered autumn. The campus scenery is completely different from when Xu Qingzhou and the others arrived. Yellow, green, and red are intertwined. Walking on the road, fallen leaves are spread on the ground, and stepping on them makes a rustling sound.

If you don't do something, you'll probably be bored to death.

Of course, to be more precise, she wanted to trick him into the research institute, saying that she could provide a full scholarship in the future, have an academician as a teacher, and have a big sister like her to provide guidance... "Too unromantic." Wu Tianyu threw a flirtatious look, wanting to tease this little brother every time, but this guy was simply a piece of wood, impervious to oil and salt, let alone shy.

Wu Tianyu pulled the office chair and slid to Xu Qingzhou's side, leaning very close to Xu Qingzhou, so that Xu Qingzhou could feel part of her soft body and heat.

"Luo Shiyi and Tang Bao." Wu.

"Xu Qingzhou!"

Finally, the conclusion was reached: Sample 04 increased in resistivity during the 6th hour, superconducting performance decreased. Overall, it was higher than Sample 03, but 3% lower in performance than Sample 02.

Xu Qingzhou was unmoved and copied things seriously.

After finishing, he continued to work on the Cramér conjecture.

At the same time, School of Physics.

Executive Vice Dean Nie Zuozhen had just finished the teaching and research meeting and returned to the office. Just after sitting down, the phone beside him rang.

Nie Zuozhen picked up the phone, and the voice of an old friend came from the other side: "Old Nie, congratulations, the School of Physics has produced another good student. I read that article, it was written very brilliantly."
