Chapter 246: This is not hygienic!

In the afternoon, Cheng Nuo and Wang Genji went to the largest library in Kyoto to clean up.
With a huge sum of one thousand yuan in their pockets, they looked full of pride.
"Engineering Mathematics", there is a way to build the helmholtz equation system, buy it!
"Acta Mathematica", which contains several papers on the one-dimensional Helholtz equation in polar coordinates, also bought!
"Research in Advanced Mathematics" contains a chapter about the high-order difference scheme and algorithm of the wave equation, buy them all!
"Young A Bin" mainly tells the life of A Bin's legendary life when his high school grades are not ideal, and it has a good learning significance for them. So Wang Genji took Cheng Nuo to buy a complete set of upper and lower volumes.
By the way, I also bought an inspirational book about a woman named Bai Jie, which is worth reading while lying in bed at night.
"Really heavy!"
Wang Genji turned the heavy stack of books in his hands and couldn't help but speak.
Check out, leave!
A total of more than 20 books cost more than 500 yuan. Then the two bought some necessary stationery such as whiteboards, scratch paper, gel pens and the like from a nearby stationery store.
After it was over, the two of them carried heavy things in their respective hands.
And the project funding of 1,000 yuan, there are more than 300 left. This is the result after they bought such a lot of things.
Sure enough, people in the Department of Mathematics really save money when doing topics.
Thousand yuan, put it on other topics, I am afraid that even a wave cannot be lifted. But for mathematics subjects, just give them paper, pen, and sometimes a computer, and everything can be solved.
The sun was still very poisonous in October afternoon. The two wiped sweat from their foreheads and stood by the road waiting for the bus.
At this time, the sound of a starter's song rang in their ears.
"Roasted gluten, grilled gluten~~"
"My roasted gluten!"
"Let you eat happily every day~"
"Roasted gluten, grilled gluten~~"
"Let you eat real benefits!"
A dark-skinned uncle with a watermelon haircut and a blue-and-white coat pushed a gluten-baked stall and approached them.
"Boy, do you have some grilled gluten?" Brother Gluten asked them enthusiastically.
The rich fragrance from the smeller. Classmate Wang Genji swallowed.
Baked gluten, this is a good thing!
"How much is a string?" Wang Genji asked, swallowing as he walked to the gluten-baked stall.
"Two yuan a string, absolutely affordable! Boy, how many strings do you want?"
"Give me eight skewers. By the way, do you have a drink here? Give me a bottle too. I'm a bit thirsty."
"Yes, some."
The gluten brother passed the seasoned eight gluten and a bottle of beverage to Wang Genji.
"Ah, delicious!"
Wang Genji took a bite of gluten, with an intoxicated expression on his face, thumbs up full of praise, "Boss, you roasted gluten, two words: delicious!"
Wang Genji couldn't help but took a big bite, stuffed the gluten into his mouth, chewed with his cheeks, and said slurredly, "Boss, since your roasted gluten is so delicious, why not go to those schools. Buy, there should be more money than selling here, right?"
"Hey, you don't know. I am unhygienic and can't be eaten by children!" Brother Gluten said with a conscience in the industry.
Wang Genji stopped chewing and looked at the lonely sign in his right hand, "..."
What am I... still a kid!
"Genji senior, the car is coming!" Cheng Nuo waved to Wang Genji.
At this time, Wang Genji no longer struggled with the question of Jian's health. While taking money out of his pocket, he asked, "Boss, how much is the total?"
"A total of eighteen, you can just give me twenty, no need to look for it."
"Okay. Come on, here you are." With that, Wang Genji handed a twenty-yuan bill to Brother Gluten, and then hurriedly walked to the front of the car, opened the door and got on the car.
Within a few minutes, a wailing sound came from a car that had driven far from here.
"Sister, I belong to the mathematics department, so I got two dollars for the gluten buyer!"
…………
Because of the "two yuan" incident, Wang Genji, who has always been self-proclaimed as a mathematics genius, looked gloomy along the way. There is even a little doubt about life.
Back at school, because Cheng Nuo didn’t know where the other two seniors’ dormitories were, Senior Wang Genji’s eyes were even more hollow, and it was almost impossible to recover from the shock just now, so he could only sell the books and stationery he had sold Put them back in their dormitory.
"Fuck! Cheng Nuo, didn't you just come back from robbing the bookstore? Why did you buy so many things?" Yuan Hua couldn't avoid making a fuss when seeing the pile of things that Cheng Nuo brought back.
Cheng Nuo wiped the sweat on his forehead and smiled triumphantly, "Of course it's studying! I don't want to be like you, indulging in the world of chicken eating, I can't extricate myself. I am a good student who loves to study. If I don't study for a day, I feel uncomfortable!"
Yuan Hua: "..."
Ha ha……
I don’t know, when I ate chicken a few days ago, who was the one who played the most and called everyone to play all night?
"Come on, I would like to trouble you a few brothers, there are still things that haven't been brought up here, please do me a favor." Cheng Nuo used the roasted gluten that senior Wang Genji gave him when he got off the bus as a reward.
"No problem." The three of them went downstairs with Cheng Nuo while eating roasted gluten.
…………
On the sixth day of National Day ~EbookFREE.me~, while most students were still enjoying the wonderful National Day holiday, Cheng Nuo had to devote himself to the research of the subject project.
The first part that Cheng Nuo is responsible for is to derive a two-dimensional helmholtz equation linear system through a one-dimensional helmholtz equation combined with a compact difference scheme.
Among the five parts of the subject framework, this is the simplest part. So Jiang Shuobo handed this task to Cheng Nuo, the youngest in grade.
At the same time, the first part is also the most basic part of the whole subject.
If the linear system obtained by the discrete two-dimensional helmholtz equation of Cheng Nuo's d (joint compact difference) format has not been calculated, the work in the following four parts may not be carried out at all.
After all, the subject name of this project is to study the two-dimensional helmholtz equation d format!
It's stressful!
This is the first time Cheng Nuo has received such a demanding task.
However, as the king of Miyoshi in the new era, Cheng Nuo feels that he must be obliged to perfectly complete the task that was entrusted to him.
So today, Cheng Nuo got up early. Prepare to start his daily scientific research routine.
In order to pretend to be forced, Cheng Nuo must do his best.
The dormitory environment is too noisy, the library is too far away, and there are too many beloved dogs, Cheng Nuo is worried that she will not be able to accept the psychological gap.
So Cheng Nuo went to an...Internet cafe near the school. Turn on a machine.
Then, under the confused eyes of the people eating chicken in the Internet cafe, they slowly took out the treasures from the schoolbag.
Draft paper, gel pen, compasses, eraser...
"Discrete Mathematics and Its Applications"
"Proof and Refutation-Logic Discovered in Mathematics"
"The application of richardson extrapolation"
