Replay 07: Opening the Temple of Learning

Chapter 53: I need points urgently to buy you (Please read on!)

Lu Shan returned all the books he borrowed last time.

The efficiency in the Singularity Laboratory was indeed very high. Poincare and Lu Shan had finished digesting all the borrowed books.

Singularity Lab now has computers that can be used to search for papers on CNKI and VIP.

However, many more detailed information and papers cannot be found on the Internet. You still have to borrow them from the library or go to the electronic reading room on the sixth floor to download the corresponding papers.

This time, Lu Shan not only looked for books and papers related to the development of foreign 3G networks, but also found some cutting-edge papers in topology, which was what Poincaré required.

Although Poincare created topology.

However, topology has made great progress in the past hundred years and plays an important role in cosmology, physics, computers, biology, etc.

Poincare also needs to be studied.

Xiao Pang is thirsty for knowledge every day. According to his understanding of science, it shouldn't take long for him to catch up with the world's most advanced level.

Lu Shan borrowed books such as Differential Manifolds and Riemannian Geometry, Numerical Solutions of Differential Equations, and Differential Geometry for himself.

Lu Shan has a strong sense of planning and discipline. He is determined to make good use of the properties of the Singularity Laboratory (high concentration and no time limit) to complete his undergraduate studies before college. If he has extra time, he will challenge himself to complete relevant studies in mathematics at the graduate level.

After finding the book and downloading the paper, Lu Shan wandered around the sixth floor looking for opportunities to gain points.

There are less than two weeks until the Spring Festival and school holidays are about to begin.

After the Spring Festival, Poincare had only ten days left before leaving.

The only way to extend your stay in Poincare is to redeem points.

There are two ways to redeem.

One method is to exchange 10 points for one day of stay.

One is 150 points, which can be subscribed monthly.

The last type is 1000 points and can be subscribed for an entire year.

Lu Shan seriously doubted whether the Singularity Laboratory was built by Penguin, and that only by spending money (points) could one become stronger.

Lu Shan now has 242.78 points remaining, which is enough to book Poincare for more than a month at most.

Lu Shan must have been reluctant to part with Poincare. It makes sense that Poincare is known as the last all-round mathematical genius.

It can be used for attack or defense, can be used to write scientific research papers, and can be used for innovation. It is very easy to use.

The most important thing is that Lu Shan spent a lot of points and energy to enable Poincare to catch up with the most advanced fields of mathematics.

If the next time I draw a scientist spirit, I accidentally draw Archimedes from BC or Lu Ban from the Spring and Autumn Period...

Lu Shan: "Little one, let me tell you from the Nine Chapters on the Mathematical Formula..."

Lu Shan: "Lao Lu, let me tell you what screws are. I spent a lot of points today to bring you self-tapping screws, machine screws, triangular screws and trapezoidal screws."

Lu Ban: "What is a screw?"

Lu Shan: "Uh... it's the nail with the spiral pattern underneath."

Lu Ban: "What is a nail?"

Lu Shan: "Uh, it's made of iron, and the front is sharp..."

Lu Ban: "What is iron?"

Lu Shan: "... Forget it, let's not talk about screws anymore. I'll still explain to you "How the Steel Was Tempered". No, you should continue to bury it in the soil and don't come out. Remember to bury it deeper."

Open an introductory class for scientist Yingling Science and Technology Kindergarten?
The scene was so horrifying that Lu Shan couldn't help but shiver.

Poincare must never be let go, or at least must be completely squeezed dry before being let go.

At the same time, Lu Shan needs points to obtain more heroes, upgrade the laboratory to increase the number of heroes, or exchange for corresponding technologies. How can I get more points?

This period of time is not suitable for publishing papers because Lu Shan does not have Tang Yi's resources.

Even if a paper is successfully published and he is the second author, Lu Shan is very clear that whether it is the "Annals of Mathematics" or other journals, without the help of a resource-rich person like Tang Yi, even if he can publish a paper, it will not be so fast.

Therefore, there are currently three ways to quickly gain points: one is to have people answer questions at the library, one is for Lu Dehai's factory to continuously output products using its own technology, and the third is for published papers to be cited or read and generate some insights.

Lu Shan was looking for prey in the electronic reading room on the sixth floor.

There may be graduate students working on assignments and papers on the first to fifth floors, but the proportion of undergraduates is too large and the points they earn are too few.

Most of the people on the sixth floor come to check papers. The proportion of graduate students is higher, and the probability of obtaining large points is also higher.

Lu Shan was actually looking for Qiao Weiwei intentionally or unintentionally. Why wasn't this silly and cute senior sister who could get a lot of points here today?

When Lu Shan answers questions for others, he has to be selective with the people he helps, preferably those in mathematics and science and engineering. After all, if he doesn't understand something, he can ask Poincare.

But it also involves the input-output ratio.

If it involves difficult math or science problems that you don't understand very well, the best way is to collect more, ask Poincare for advice all at once, and then get the answer. This way you will get more benefits.

After all, it costs two points to enter the Singularity Laboratory once. If you only earn 0.1 points from the opponent, it would be a loss-making business.

Coincidentally, there was a girl wearing glasses in front of me who was checking her thesis against the one on the computer.

The content is related to optimization algorithms constrained by differential equations.

The girl looks like she is not doing very well in her studies.

My whole body is saying, lots of points, come quickly.

Solving the problem of constrained optimization of differential equations requires the comprehensive use of multiple methods, including discrete methods, optimality theory, optimization algorithms, etc., and requires theoretical analysis and numerical solution of the problem, which is quite difficult.

Lu Shan has studied this problem in his undergraduate professional courses recently, and discussed the professional field of graduate students with Poincare, so he knows the answer.

Lu Shan stood secretly behind and read every page the senior student turned.

There were no problems at the beginning, but when he turned to about page ten, Lu Shan saw that there was a problem with the paper.

The setting of several differential equations in the variational adjoint method model is wrong, and the control variables (model parameters, initial conditions
The error in setting the parameters or boundary conditions, etc., makes the subsequent gradient derivation process meaningless.

Mathematics is like this, if you make a mistake at one step, all of them will go wrong.

Moreover, you may not find the error in the process of deduction until the final answer and result are different, and then you go back and reverse the error.

The senior student with glasses was anxiously looking for literature, but she also got stuck here.

Just as Lu Shan was about to speak, the senior turned around and looked at him warily, then instantly closed her paper, walked away with the information, and switched to another computer.

Lu Shan was speechless and had to give up the senior girl with glasses and choose another one.

He also felt very embarrassed. It was like being a psychopath to go up to someone and explain the problem to him.

But he compromised in the face of points.

But after walking around, he found that there was no one around him who was majoring in mathematics, and he didn't know much about literature, English, medicine and other majors.

Helpless, Lu Shan came to the side of the glasses-wearing senior sister again, and deliberately kept a certain distance. In order to avoid misunderstanding, he spoke as quickly as possible: "Hello, senior sister! I just accidentally saw your paper and found that you have set several control variables incorrectly."

The senior student bit her lower lip with her teeth, then seemed to have made up her mind. She wrote her cell phone number and QQ number on a piece of paper and handed it to Lu Shan.

Nowadays, boys have evolved their pursuit of girls into something so cute. Why not get straight to the point?
Lu Shan: “???”

At this time, Qiao Weiwei also came to the sixth floor. She saw Lu Shan with a wretched look on his face and hurried over: "Teacher!"
