Chapter 409

Monday, 8:00 PM.

Living room.

Xu Qingzhou was lying on the sofa chatting with Xu Zhengyang and the others in the dorm. It was so lively in the dorm while he was away; Xu Zhengyang had broken up once these past few days and was in an emotional tug-of-war with Chen Shiqi.

Kong Xianbo could be considered to have truly sealed his heart and loved no one. Although he was already recommended for graduate school, he still found an internship unit, calling it experiencing the life of a working person.

Zhai Ziqiang and Zhang Shuyi, who competed with Kong Xianbo for class monitor at the beginning of the semester, got together. In Xu Zhengyang's words, they caught up with a twilight romance; they were secretly together before, and now both were recommended for graduate school at the school, so they didn't hide it anymore.

Traveling here today, playing there tomorrow, their little life was quite comfortable.

Song Yao was writing a thesis at the desk, about corporate structure, planning to finish it by the end of October, counting as the first SCI since coming to Harvard.

This period was so busy; besides following the project, she had to be busy with her own thesis, almost a life of school and home, two points and one line.

The keyboard sound in the living room disappeared. Song Yao stretched, stepped on slippers, came to the sofa, and squeezed into Xu Qingzhou's arms to rest.

"Crushing people." Xu Qingzhou muttered, adjusted his position to let Song Yao lie more comfortably.

"Shut up!"

Xu Qingzhou smiled, couldn't help but take a breath, the familiar fragrance immediately drilled into the tip of his nose; he actually quite liked the feeling of the school beauty Song sticking to him.

This girl's temper is violent, but when she nests in his arms, she is a little one, very cute.

Xu Qingzhou was holding Song Yao in his arms, typing to tease everyone's rich emotional life, when he suddenly found something wrong, raised his eyes, "What are you touching me for?"

The school beauty Song was lying on him, and these hands were arching back and forth in his clothes; she had rebelled against heaven again.

"I didn't ask when you touch me usually."

Song Yao closed her eyes and said dissatisfiedly, sighing in her heart that it's no wonder this guy likes to pinch her; it feels very comfortable to touch.

"You clearly said I was a pervert." Xu Qingzhou reminded her.

Song Yao pouted, didn't speak, and even retaliated by pinching a few times.

"Heh, someone, only allows the magistrate to set fires, not the common people to light lamps..."

Xu Qingzhou discovered the girl had already put her hands on his waist.

The school beauty Song's way of threatening people was indeed simple and unadorned.

Letting a female hooligan touch him up and down, Xu Qingzhou chatted with Xu Zhengyang and the others for a few sentences, but remembered it seemed he hadn't looked at Weibo for a long time.

The comment section and private messages were quite lively.

【Seven Walnuts】: Xu God has been a bit quiet recently, making people feel a bit unaccustomed.

【Must Lose Weight for New Year】: Xu God, time to come out and act cool.

【I Love Xu God】: Xu God went to MIT to study, probably quite busy now.

【Sodium Ion 1323】: Guess what I saw!

Below was attached a photo, the content was the announcement of MIT's project review.

【Wang Shiba's Little Moon】: Awesome!

【Little Gu Who Doesn't Close Shop】: If my elementary school Chinese is okay, I should have seen the four words "Riemann Hypothesis".

【Laughing Every Day】: Xu God is walking less and less on the beaten path.

【Native Three-Body Person】: I'll put these words here today; if he can really do it, I'll stand on my head and wash my hair.

【Nainai Sheng Ah】: Brother upstairs, stabilize first; wait until the brother who shouted to stand on his head and eat shit fulfills it before it's your turn.

【Person Wearing Straw Sandals】: Jokes are jokes, but one has to say, this difficulty is too great; Riemann Hypothesis, ah, in more than two hundred years, countless people have followed one after another, but the result is just that little bit.

【roay】: No, no, no, I think there is hope; Xu God solved the Twin Prime Conjecture and the Polignac Conjecture, the prime number research field has had a qualitative breakthrough, Riemann Hypothesis is still possible to be solved.

【Waiting for the Wind】: Right, the proof of these two conjectures has incomparable significance for the proof of the Riemann Hypothesis.

Xu Qingzhou sighed; netizens are very concerned about him, it's a pity there seems to be nothing to share now.

Song Yao pressed her face against Xu Qingzhou's chest, watched Weibo with him for more than ten minutes, and had touched enough, before preparing to climb up.

But as soon as she got up, her slender waist was hugged by the boy underneath.

"What are you doing?"

Song Yao lay on Xu Qingzhou, looking at him vigilantly; she should have thought earlier that this guy wouldn't suffer a loss.

"What am I doing? Teacher Song, you wouldn't really think it can be touched for free, right."

Xu Qingzhou hugged the girl's slender waist, his hands already starting to be dishonest.

"Xu Qingzhou, you touched me before too."

Song Yao was anxious.

"Next time you can touch back, rest assured, I won't resist."

"..."

Soon, amidst Xu Qingzhou's begging for mercy, Song Yao escaped. Before leaving, she glared fiercely at this guy; moving hands and feet in broad daylight.

Xu Qingzhou covered his waist, which was pinched by the school beauty Song, and sighed.

After finishing class on Monday, Xu Qingzhou's life returned to calm, but the MIT mathematics department was a bit restless.

First, because Xu Qingzhou's substitute teaching set off a wave of heat; currently, anyone studying mathematics wouldn't be unfamiliar with this rising young mathematician Xu Qingzhou.

Such a big shot in the number theory circle teaching... always makes people look forward to it, not to mention that during the period, there were PhDs who went to listen to the content, claiming they benefited a lot.

So, a considerable number of people had already set their sights on next week's class.

The second hot topic was because of the question Xu Qingzhou left behind.

He still miscalculated; there really aren't that many cheaters in the world. The question left by this number theory big shot is quite challenging. The freshmen were the first to bear the brunt, completely helpless; students of other grades were curious and took the question, but didn't do much better than the freshmen.

Finally, it was a sophomore male student who announced he found the answer.

September 10, another weekend.

A week passed, Xu Qingzhou was still stuck on the calculation of the third proposition inequality; it could be described as difficult to move forward. This inequality is different from the first two; it belongs to the logical chain connecting the first two inequalities.

The current problem is that the condition regarding whether the L-function equals 0 when s<1 cannot be satisfied.

To put it colloquially, Xu Qingzhou currently needs to hand-rub a bicycle; he rubbed the wheels and the frame out, but got stuck on the brakes.

As for the research on pentaquarks, there was slight progress.

The total detection efficiency of the simulated detection and the background from the edges change smoothly on the Λ decay space, so they cannot generate the narrow peak seen in j\ψp.

In other words, there might really be other particles inside the abnormal peak.

And what's more troublesome now is that the pentaquark particle was only officially observed in 2015, and the LHC's experimental data is limited, completely unable to support the use of models for large-scale data screening.

This means that more refined mathematical tools need to be constructed, only then will there be a chance to find what one wants.

Two huge mountains lay in front of Xu Qingzhou, but he was busy with other things now.
