Chapter 117: Finally went crazy

A week passed in a flash.

Xu Qingzhou looked lonely as he came out of the classroom, intending to walk around the school to relax. The proof of the Cramér conjecture had hit a bottleneck; the two proof methods he had planned had both hit a dead end.

In the classroom, besides Xu Qingzhou, there were three girls studying together.

Seeing Xu Qingzhou go out, someone let out a breath.

"Just in one afternoon, he used over ten sheets of draft paper. When I went to the restroom just now, I specifically took a glance—dense calculation formulas, most of which I didn't recognize."

"For a full 3 hours, he didn't even go to the restroom once."

"Kidneys are good." One of the girls commented.

"Mm?"

In the classroom.

Read! {

A night rain had just fallen last night, and the air was cold but very fresh, making his brain much clearer.

She glanced at Xu Qingzhou, thinking to herself if this guy had been staying up late again, with two dark circles under his eyes. He seemed to be the same style as that doctoral student named "Wang Wei" she had seen in the canteen last time.

Still have to use the PN model.

Wait!

Many tourists were taking photos by the lake, and there were also students from the Art Academy sketching.

November 5th, 4 days passed in a flash. Xu Qingzhou basically lived a life of dormitory, canteen, and empty classroom, skipping two political classes during the period.

The autumn scenery of Jingda Yan Garden is unique.

"I'm not coming, what if you slack off?" Song Yao pouted.

Perhaps, it can be used.

Having been running around like this for three or four days, he felt uncomfortable all over if he didn't come out to move around.

Looking at the filled structure diagram, Xu Qingzhou's face was filled with uncontrollable surprise. If this was the case, perhaps it was feasible! The few girls all let out a breath, looking at each other, the meaning in their eyes self-evident: "Finally... he went crazy."

Xu Qingzhou walked through the island pavilion in the middle of the lake and walked to the east bank of the lake, during which he took photos of Song Yao who was in class, causing Song Yao to be envious.

!.

Under the surprised gazes of the three girls, Xu Qingzhou walked into the classroom eagerly, picked up a pen, and brushed down the inspiration he had just had on the manuscript.

Math is a tool for studying physics, but who says physics can't feed back into math and provide new research ideas for math?

That's right, at 6:00 PM, after simply gnawing on a piece of bread in the dormitory, he put on the sports suit Song Yao bought him, carried his water cup, and went out.

Besides sleeping and eating, he was basically doing calculations.

(pn+1-pn) / (lnpn)^2 = 1 n→∞ limsup pn represents the nth prime number.

Looking at Song Yao who suddenly appeared, Xu Qingzhou said: "Didn't I tell you to rest in the dormitory?"

"That's right."

Quantum algebra and category theory provide new perspectives for the abstract description of quantum entanglement. In addition, optimization theory and probability theory also have wide applications in the measurement, verification, and error correction of quantum entanglement. At this moment, he caught the tail of inspiration.

She was wrapped very thickly in clothes, holding a cup, without makeup. Compared to usual, her skin was fair and tender, having a more pure beauty, and at the same time, a bit more fragility that made one want to protect her. He walked around again, preparing to go back. Although there was still no clue, walking around made his whole person feel much more comfortable.

The Cramér conjecture asserts the existence of a constant c such that for all sufficiently large natural numbers x, there exists at least one prime gap no larger than c(logx)^2.

Xu Qingzhou let out a breath and simply emptied his brain to take a rest.

Different from before, he now pays more attention to physical health.

"We thought we were already friends, didn't expect that we didn't even have this bit of trust between us."

Quantum entanglement graph theory and combinatorics can be used to study entanglement structures in many-body quantum systems.

At this moment, autumn was in full swing, sunlight climbed onto the ginkgo tree tips, the red of maple leaves dyed the lush grass and trees, the autumn wind blew, and the lake surface rippled.

He walked a new path of proof, which could be considered a combination of the first two methods, using mathematical tools such as analytic number theory series and integrals.

Many leaves had fallen, and two leaves slid down from the branches, drawing two similar and beautiful arcs in the invisible wind.

When Xu Qingzhou arrived at the May 4th Sports Field, he was surprised to find that Song Yao was also there.

During this period, he seemed to have returned to the time when he was desperately working on experiments.

Although quantum entanglement is far from the Cramér conjecture, some places are indeed worth learning from.

This is a model Xu Qingzhou wrote himself, which can be considered one of his biggest gains in the past month or so, capable of extremely fast analysis of the relationship between adjacent prime numbers.

Quantum entanglement, two entangled particles, even after they are no longer coupled, still maintain a connection between them.

If it were usual, he wouldn't have the habit of carrying a water cup, but this period is the beginning of the month, Song Yao is on her period, and cannot exercise.

Xu Qingzhou's footsteps stopped abruptly, staring fixedly at the falling leaves. Just in the moment just now—a flash of inspiration.

Too difficult.

Graph theory, combinatorics, optimization theory... these things were all things he was good at before.

Seeing the other two looking at themselves, this girl coughed lightly, "Math majors, too crazy."

Xu Qingzhou walked slowly, recalling the details of the Cramér conjecture in his mind.

The Cramér conjecture talks about a certain mathematical property between two adjacent prime numbers.

Entering November, the temperature dropped suddenly, and at night it could even drop below zero. Walking on campus, the unique scenery seen in summer was basically covered under thick clothes.

Although his running partner wasn't there, Xu Qingzhou didn't rest. Having exercised continuously for two months, he realized the joy of sweating.

Xu Qingzhou stopped, something flashed in his mind, but he couldn't grasp it.

Xu Qingzhou shook his head and sighed.

"A man's mouth, a ghost's lie." Song Yao snorted coldly, saying while walking toward the place where the two usually warmed up.

"Finished watching, can go back now."

"The dormitory is too stuffy."
