Chapter 243 This is Unhygienic!

In the afternoon, Cheng Nuo and Wang Genji came to the largest library in Kyoto to clean up.

With a huge sum of 1000 yuan in their pockets, they looked full of pride.

"Engineering Mathematics", which contains the construction method of the Helmholtz equation system, bought it!

Acta Mathematica, which contains several papers on the one-dimensional Helmholtz equation in polar coordinates, is also bought!
"Advanced Mathematics Research", one of the chapters describes the high-order difference scheme and algorithm of the wave equation, buy them all!
"Young Abin" mainly tells about the legendary life of Abin who did not perform well in high school, and it is of great learning and reference significance for them.So Wang Genji dragged Cheng Nuo to buy a full set of volumes.

By the way, I also bought an inspirational book about a woman named Bai Jie, which is worth reading carefully when we lie in bed at night.

"It's really heavy!"

Wang Genji shook the heavy stack of books in his hands, and couldn't help but speak.

Check out and leave!
There are more than 20 books, and the total cost is more than 500 yuan.Then the two bought some necessary stationery such as whiteboards, draft paper, and gel pens from a nearby stationery store.

After the end, both of them carried heavy things in their hands.

And 1000 yuan of project funds, there are more than 300 yuan left.This is the result after they bought so many things.

Sure enough, people in the Department of Mathematics really save money when doing projects.

If 1000 yuan is spent on other subjects, I'm afraid it won't even make a splash.But for mathematics subjects, as long as they are given paper and pen, and sometimes a computer, everything can be solved.

The sun was still very poisonous in the afternoon of October. The two wiped the sweat from their foreheads and stood by the road waiting for the bus.

At this time, touching singing sounded in the ears of the two of them.

“Roasted gluten, roasted gluten~~”

“My baked seitan!”

"Let you eat happily every day~"

“Roasted gluten, roasted gluten~~”

"Let you eat real benefits!"

A dark-skinned, watermelon-covered uncle wearing a blue and white coat pushed a gluten-roasting stall and came to the two of them.

"Boy, would you like some skewers of gluten?" Brother Gluten asked the two of them enthusiastically.

The rich aroma that the smeller exudes.Wang Genji swallowed his saliva.

Baked gluten, this is a good thing!
"How much is a skewer?" Wang Genji walked to the stall of roasted gluten and asked, swallowing his saliva.

"Two yuan a skewer, absolutely affordable! Boy, how many skewers do you want?"

"Bring me eight sticks. By the way, do you have any drinks here? Get me one too. I'm a little thirsty."

"Yes, yes."

Brother Gluten handed Wang Genji the seasoned eight sticks of gluten and a bottle of drink.

"Ah, delicious!"

Wang Genji took a bite of gluten, with an intoxicated expression on his face, he gave a thumbs up full of praise, "Boss, you roast gluten, two words: delicious!"

Wang Genji couldn't help taking another big bite, stuffed the whole gluten into his mouth, chewed with puffed cheeks, and said inarticulately, "Boss, since the baked gluten you sell is so delicious, why don't you go to the gates of those schools?" Buying, there should be more money than selling here, right?"

"Hey, you don't know. This is unhygienic and cannot be fed to children!" Brother Gluten said with a conscience in the industry.

Wang Genji stopped chewing and looked at the solitary stick left in his right hand, "..."

I'm... I'm still a child!

"Senior Genji, the car is here!" Cheng Nuo waved to Wang Genji.

At this time, Wang Genji didn't worry about Jian's health any more. He took money out of his pocket and asked, "Boss, how much is the total?"

"A total of eighteen, you can just give me twenty, no need to look for it."

"Okay. Here, here you are." Then, Wang Genji handed a 20 yuan bill to Brother Gluten, then hurriedly walked to the called car, opened the door and got in the car.

A few minutes later, there was a howl in a car that had driven far away from here.

"Sister, I'm from the Department of Mathematics, and I was cheated of two yuan by someone who bought gluten!"

…………

Because of the "two yuan" incident, Wang Genji, who has always claimed to be a mathematical genius, seemed depressed all the way.Even a little suspicious of life.

Back at school, Cheng Nuo didn't know where the other two seniors' dormitories were, and senior Wang Genji had empty eyes. It was almost impossible to recover from the shock just now, so he could only take the books and stationery he had sold. Put them all back to their dormitories.

"Fuck! Cheng Nuo, didn't you just come back from robbing the bookstore? Why did you buy so many things?" Seeing the huge pile of things Cheng Nuo brought back, Yuan Hua couldn't help being fussy.

Cheng Nuo wiped the sweat from his forehead and smiled triumphantly, "Of course it's study! I don't want to be like you, addicted to the world of eating chicken and cannot extricate myself. I am a good student who loves to study. If I don't study for a day, I feel bad all over!"

Yuan Hua: "..."

Ha ha……

I don't know, but who was the one who had the most fun while eating chicken a few days ago and called on everyone to play all night?

"Come on, my brothers, please help me. There are still things below that haven't been brought up. Please help me." Cheng Nuo rewarded him with a few sticks of roasted gluten thrown to him by senior Wang Genji when he got off the car.

"No problem." The three of them went downstairs with Cheng Nuo while eating the roasted gluten contentedly.

…………

The sixth day of National Day.

While most of the students were still enjoying the wonderful National Day holiday, Cheng Nuo, who was struggling, had to devote himself to the research of the project.

The first part that Cheng Nuo was responsible for was to introduce the linear system of the two-dimensional Helmholtz equation through the combination of the one-dimensional Helmholtz equation and the compact difference scheme.

Of the five sections of the project framework, this is the easiest.So Jiang Shuobo gave this task to Cheng Nuo, who was the youngest in the grade.

At the same time, the first part is also the most basic part of the entire topic.

If Cheng Nuo didn't even calculate the linear system obtained by discretizing the two-dimensional Helmholtz equation in CCD (combined compact difference) format, it would be impossible to carry out the work in the following four parts.

After all, the subject name of this project is to study the CCD format of the two-dimensional Helmholtz equation!
The pressure is huge!
This was the first time Cheng Nuo had received such a high-profile task.

However, as the king of three good things in the new era, Cheng Nuo felt that it was his duty to perfectly complete the task of preventing him.

So today, Cheng Nuo got up early.Ready to start his day of scientific research.

In order to pretend to be aggressive, Cheng Nuo had to do his best.

The dormitory environment was too noisy, the library was too far away, and there were too many loving dogs. Cheng Nuo was worried that he would not be able to accept the psychological gap.

So Cheng Nuo went to a... Internet cafe near the school alone.Turned on a machine.

Then, under the confused eyes of everyone eating chicken in the Internet cafe, he slowly took out treasures from his schoolbag.

Scratch paper, gel pen, compass, eraser...

"Discrete Mathematics and Its Applications"

"Proof and Disprovement - Logic Discovered in Mathematics"

"Application of Richardson's Extrapolation"
