I Just Want to Be a Quiet Top Student

"Algorithm, I understand!" Xiao Junlong is talented and intelligent, and he quickly realized the way from Weiteng's prompt.

"Xiao, come on." Wei Teng smiled and handed the paper cup to Xiao Junlong.

Xiao Junlong performed his magical skill of snapping his fingers and poked a hole in the bottom of the paper cup.

Some men are used to growing the nails of their little fingers, such as Xiao Junlong. This habit is mainly due to scientific research considerations. It is more convenient to poke a paper cup or something.

Pressing the water outlet switch with his left hand, Xiao Junlong held the paper cup in the air with his right hand to receive water.

Under the action of the dual system of the fluid mechanics system of the water dispenser and the gravity of the earth, the water column penetrates the hole at the bottom of the paper cup and flows into the groove of the water dispenser.

"Through this experiment, we observed that when the water velocity remains constant, no matter what external force I exert on the paper cup to cause its deformation, there is only one final result, that is, all the water in the paper cup will leak out." Xiao Junlong Looking at Wei Teng, he said adoringly: "Professor Wei Teng is a real master. He used the simplest experiment to reveal the essence of the most difficult problem."

Wei Teng kept a mysterious smile and said nothing, Shen Qi asked: "So, Dr. Xiao?"

After Xiao Junlong finished the simple experiment, he came to the whiteboard and wrote a few lines of formulas on the whiteboard with a water-based pen: "There are many kinds of finite element algorithms that satisfy the velocity and pressure conditions. Through the inspiration of this experiment, we can preliminarily draw up the local Gaussian integral The algorithm is an effective way to solve the general solution of the N-S equation with universal significance. Therefore, the focus of the next step should focus on the local Gaussian integral algorithm."

"Well, Dr. Xiao's point of view is feasible." Zhou Yu'an also thought so, but his reaction was a bit slower, allowing Xiao Junlong to show off his perception first.

Shen Qi was noncommittal, he asked Wei Teng: "What do you think, Edward?"

Wei Teng came to the water dispenser, squatted down, and made an unexpected movement.

Wei Teng tilted his neck and opened his mouth, pointing his mouth at the water outlet, and at the same time pressed the water outlet switch with his hand.

The water column leaked down and flowed into Wei Teng's mouth.

"Water?" Zhou Yu'an was dumbfounded.

"What kind of operation is this?" Xiao Junlong frowned, not knowing why.

"Could it be..." Zhou Yu'an had a sudden epiphany, he trembled because of over-excitement: "I remember when I was a Ph. An infinite flow algorithm for equations!"

Xiao Junlong fell into deep thought: "Infinite flow? Do you want to know the meaning of life?"

Zhou Yu'an: "Don't get too far away, Lao Xiao, you don't understand what an infinite flow is! In one sentence, it is an accurate and unlimited algorithm for solving the destabilizing parameters of the N-S equation with a large Reynolds number!"

"There is such an algorithm? But this sentence seems to be self-contradictory!" Xiao Junlong half-believed, his Yan University doctoral supervisor had never taught him any infinite flow algorithm, and he had never heard of it.

At this time, Weiteng finished the demonstration. He stood up, nodded to Zhou Yu'an and said, "I discussed the infinite flow algorithm of partial differential equations with Professor Figali. It only exists in a very small academic circle. It has not been reported publicly.”

Wei Teng turned to look at Shen Qi: "Qi, you should know this algorithm, it is Princeton's original."

Shen Qi said: "Yes, I know, and I have studied it. But the problem is that the infinite flow algorithm for partial differential equations is similar to N-S equations. It has applicability, but it has never been thoroughly proved that its proposition is correct. It is also the reason why it has not been publicly reported. That is to say, if you use the infinite flow algorithm to solve the N-S equation, it is equivalent to using one hypothesis to verify another hypothesis. We don't need a hypothesis now, what we need is 'Euclidean's axiom'."

Euclid's academic contributions were memorized by several people present.

Euclid used ten axioms to derive 23 definitions and 467 propositions, thus constructing the classic and immortal Euclidean geometry system.

Axioms are commonsense cognitions, basic propositions that do not require proof.

Theories based on hypotheses cannot be widely recognized by the academic community. Shen Qi needs impeccable "axioms".

"So, proving the infinite flow algorithm for partial differential equations is a prerequisite for solving N-S equations. Do you agree with my point of view?" Shen Qi asked everyone.

Witten: "Agreed."

Zhou Yu'an and Xiao Junlong: "Totally agree."

"Then do you have a specific idea?" Zhou Yu'an asked Shen Qi.

"Let me do an experiment too." Shen Qi walked to the water dispenser. In today's academic exchange meeting, this water dispenser is the undisputed protagonist.

"Hey!" Shen Qi let out a clear whistle, and pulled out the pure water bucket directly, pulling out the mountain with great force.

Zhou Yu'an was in a bunker, Xiao Junlong was in a daze, and even Wei Teng showed a puzzled expression.

Shen Qi pressed the water outlet switch, a trickle gushed out of the water outlet, and stopped after a while.

"This trick is called drawing fire from the bottom of the pot." Shen Qi said in Chinese, and then spoke English to Wei Teng: "If the fire under the pot goes out, the food in the pot will not be cooked anyway. Prove that the infinite flow of partial differential equations The most effective method of the algorithm should be the direct increment method, or the decrement method. This requires further research, but at least we have a direction.”

Wei Teng's eyes lit up: "Good idea, let's do it like this!"

The four men discussed in the conference room for a whole day, did several experiments, and finally reached a consensus. To solve the general solution of the N-S equation, it is first necessary to prove the correctness of the proposition of the infinite flow algorithm of the partial differential equation. To prove that the infinite flow algorithm should start from the direct increment method or decrement method, this proof process will be very complicated and the amount of calculation will be huge. The later error analysis will be based on a huge amount of data, which is difficult for ordinary computers and requires the use of supercomputers.

No matter what, it is better to have a clear direction than to have a black eye.

Communication is very important. Some issues need to be discussed collectively. By integrating the highlights of each person's academic thinking, a powerful collective wisdom will be formed.

In fact, before Wei Teng came to China, Shen Qi originally conceived the solution to the N-S equation, which was the local Gaussian integral method + multi-scale incremental method, which was a grade higher than the algorithm Xiao Junlong realized by poking a paper cup, but still There is the troublesome problem, the instability of the algorithm.

Shen Qi was also chatting and discussing with Wei Teng and the others, and realized that there was a more serious move.

Witten is a top expert in mathematical algorithms. In order to better explain string theory, he created a set of mathematical algorithm system, for which he won the Fields Medal.

Next, Shen Qi proposed that the N-S equation project enter a substantive stage of advancement with Weiteng designing the algorithm framework, Zhou Yuan and Xiao Junlong assisting.

The N-S equation project has clearly defined the direction and set the tone of the main attack, and the team is led by Wei Teng, and Shen Qi is behind the scenes to coordinate. Zhou Yu'an and Xiao Junlong are the most capable mathematics generals in the center. This is an elite division with a good style.

For the project of the unification of mathematics, Wei Teng may also be able to help a little, but Wei Teng has limited energy at this age, so don't expect the old man to bloom everywhere.

Around 4:00 p.m. or 5:00 p.m., Shen Qi drove to the entrance of the Shuyuan, waiting for Ouye to get off work.

"I don't have a general in my hand, so I'm really strong to be a pioneer." Sitting in the car, Shen Qi sighed. It is very difficult to unify mathematics. It doesn't mean that Li Zhenqiang's level is not good. Liao Hua's force value is close to 80.

For the project of mathematics unification, apart from "Liao Hua", Shen Qi also needs at least one "Five Tiger General" super general with a force value above 95.

"There is no doubt that my wife is this super fighter." Shen Qi knew Ouye very well, and Ouye was due to give birth in more than three months.

During pregnancy and breastfeeding, Ouye is difficult to use.

"I'll fill in my wife's number theory hole first, and when she can work normally, I'll replace her." Shen Qi waited in the car until 5:15, and Ouye hadn't come out yet.

Ouye is usually very punctual when he gets off work. He leaves the office at five o'clock and arrives at the gate of the number hospital before five past five.

"Is there anything going on?" Shen Qi became nervous, and expectant fathers in this period are sensitive.

Shen Qi turned off the engine and got out of the car, entered the courtyard, and arrived at the door of Ouye's office with ease.

"You are so stupid!" Ouye's voice came from the office.

It's okay, my wife is fine, she's working overtime... Shen Qi felt relieved, he saw through the crack of the door that Ouye was educating a little girl, and made the little girl cry, so pitiful.
