Chapter 7

Go home.

Continue to focus on organizing the research content.

Wang Hao worked for another half an hour, feeling completely exhausted, so he decided to stop and rest.

Put on shoes, go out.

Take a walk around the neighborhood to relax and get to know the surroundings.

The environment near the neighborhood is quite nice.

To the east is adjacent to Xihai University, to the north is a small park. Beyond the small park is a hospital, and turning back is a wide commercial street.

Walking into the commercial street, there is a fast-food restaurant at the corner.

Wang Hao touched his stomach, feeling a bit hungry, so he entered the fast-food restaurant, ordered a burger meal, and sat down to eat.

The fast-food restaurant was doing good business, with people coming and going.

While focusing on eating, he heard a cheerful voice ask, "Handsome guy, is this seat taken?"

Wang Hao looked up and found the face familiar.

Next door?

The thin girl seems to be called 'Youyou,' and the plump girl is... what was her name?

He couldn't remember for a moment.

Li Qian quickly recognized Wang Hao and pulled Gu Youyou to sit down, "It's the next-door neighbor, let's sit here!"

After saying that, she asked symbolically, "Not disturbing you, right?"

"…No problem."

Wang Hao carefully looked at the two girls, trying to recall their names for a long time, but couldn't remember, so he continued eating.

The two girls seemed interested in Wang Hao and occasionally glanced over.

Li Qian couldn't help but ask, "We don't know your name yet?"

"Wang Hao."

Wang Hao said while eating.

"You're renting by yourself, for more than two thousand, you must be working, right?"

"Uh-huh."

"What do you do?"

"Teacher."

Wang Hao took the last bite of the burger and finally lifted his head, "Checking the household registration?"

"No, no!"

"Ha ha~~"

Li Qian was a bit embarrassed, "Just wanted to get to know you."

Suddenly, it became quiet.

The two girls didn't idle while waiting for their food; they took out their books and focused on them.

Gu Youyou pondered a problem, tapping her forehead with her pen, and said to Li Qian, "Have you thought about this proof problem?"

Li Qian glanced over and said indifferently, "Gave up."

"I knew it."

Gu Youyou covered her forehead in frustration.

Li Qian sighed, "I gave up long ago. Now I regret it. During the college entrance exam, I shouldn't have chosen the math major; if I hadn't chosen the math major, I wouldn't have pursued a master's in applied mathematics; if I hadn't pursued a master's in applied mathematics, I wouldn't have encountered these complex problems."

Wang Hao was about to get up and leave but stopped upon hearing this, "You're studying math?"

"What's the matter?"

The two girls looked over.

Wang Hao was indeed surprised. In his memory, the number of female math graduate students at Donggang University was pitifully few, and none of them were particularly attractive.

At the doctoral level, female students had virtually disappeared.

He gave a big thumbs up, "Impressive! Female math students are rare."

"Let me see!"

Curiously looking at the problem on the table, he immediately understood, "C[a, b] is an incomplete metric space under the integral mean convergence..."

"This is simple!"

Wang Hao took the paper and pen, explaining and solving the problem, "This is a classic functional analysis problem. First, set the range of Xn(t), where n is a natural number..."

"Look at these three expressions; it's clear that {Xn} is a subset of C[a, b]."

"For n greater than m, d(Xn, Xm) equals..."

"If {Xn} converges in this range, it can be proven that there exists X(t)..."

"..."

"..."

"Thus, C(a, b) is an incomplete metric space under the integral mean convergence."

Wang Hao finished and carefully reviewed it again, finding no issues, and nodded in satisfaction.

For him, a graduate-level math problem was indeed a piece of cake.

Gu Youyou and Li Qian were stunned.

They followed his reasoning carefully, feeling their heads spin, unable to keep up.

However, he solved it effortlessly, without even thinking, as if he were copying the answer.

This was a graduate-level math problem!

Li Qian looked up at Wang Hao and asked again, "What did you say you do?"

"Teacher?"

"Teacher?"

Wang Hao nodded lightly and pointed to the counter, "Your number is up, go get your food."

"I'll leave first."

Saying that, he walked toward the door.

Li Qian busily fetched their food and returned to see Gu Youyou deep in thought, "What's wrong?"

"I'm thinking about what just happened."

"He's so impressive!"

Li Qian couldn't help but exclaim, "I gave up on that problem at first glance, but he wrote down the answer directly."

"Don't you find it strange?"

"Strange how?"

Gu Youyou tapped her fingers, as if transformed into Sherlock Holmes, analyzing seriously, "That problem is very difficult. The teacher said to try it, but not to expect to solve it."

"But he knew the answer at first glance, as if he had done it before."

"Even if he had done it before, he should still need to think, right?"

"And he's a teacher. Even if he graduated with a master's in math, and just happened to know this problem?"

"Is it that coincidental?"

Li Qian nodded repeatedly, also realizing, "You mean, he knew our homework and studied it in advance, just to show off in front of us?"

"But why would he go to so much trouble?"

They looked at each other.

Li Qian said with a smile, "Why don't you just give in, Youyou?"

Gu Youyou blushed and quickly said, "Don't be ridiculous. If he wants to confess, he should just do it directly. Anyway, I definitely won't agree."

"Tsk~~~"

"To be in such a fortunate position and not know it, if a guy put in so much effort to pursue me, I'd marry him on the spot!"

"Would you move in right away?"

"Get lost!"

...

The next day, the class was still at 10 a.m.

With the experience of one class, there was no need to prepare again.

Wang Hao arrived at the school around 9 a.m. and went directly to the classroom. Since it was a combined class for three classes, the number of students was slightly more than the previous day.

The same introduction, the same requirements.

He smoothly went through the process and reminded all the students to listen carefully in every class.

Then, the class began.

This time, he used a teaching coin to promote the inspiration value for the research on 'Fourier Transform.'

Wang Hao felt the class progressed more smoothly, and his mind continued to absorb knowledge, but it was not as much as the previous day.

During the class, he checked the task progress and found that the inspiration value had only increased by 31 points.

"This number is definitely less than yesterday."

"It's probably due to repetition. A single research topic definitely has an upper limit, or many students have the same ideas, which don't bring new inspiration."

"But a few dozen points of growth is still significant..."

The application research on 'Fourier Transform' continued to gain inspiration value, while the research on 'Partial Differential Equation Analysis' had very little.

So far, it had only increased by 5 points.

"It's probably related to the research difficulty and relevance."

"Since the class is about Fourier Transform, the inspiration value grows faster. Partial Differential Equation Analysis is a foundational study, with a difficulty rating of 'B.' Fourier Transform is just one method for solving partial differential equations."

Wang Hao thought carefully and understood.

He continued to engage with the students, interspersing additional knowledge to make the class content rich and interesting.

The students who listened attentively felt that Wang Hao's teaching was excellent, not inferior to the previous 'Old Li.'

The students who didn't listen...

Three were called up to stand as punishment, and one who was half an hour late was marked as absent.

...

At noon.

After having lunch, Wang Hao returned to the office to work. The application and algorithm expansion of Fourier Transform had been summarized.

He planned to split the content into three papers for publication.

One part was the application research of Fourier Transform, linking it to the solution of partial differential equations, focusing on exploration and discussion.

The other two parts were the algorithm research of Fourier Transform in constructing data models and applying them to data analysis.

The content of the latter part was substantial, and even after simplification, it would exceed thirty pages, making it difficult to submit and publish all at once.

Therefore, it would be split into two parts for publication.

In the afternoon, Wang Hao worked for more than three hours, then took a break to have a cup of coffee.

The main content of the papers was almost complete.

The remaining work was to polish the writing, adjust the format, and find an academic journal for submission.

He also studied the submission process.

The School of Science at Xihai University had a cooperative academic journal. After passing the internal editorial review, the paper could be directly published.

However, the cooperative academic journal had a very low rating, barely reaching the 'recognized' level, with no influence in the academic field.

Influential domestic journals required a significant fee for publication.

Wang Hao decided to submit to an international journal—'Journal of Computational Mathematics and Information Engineering.'

'Journal of Computational Mathematics and Information Engineering' is a professional academic journal in mathematics and computer science, focusing on publishing research in data architecture, algorithms, and information communication.

In the fields of computational mathematics and algorithms, 'Journal of Computational Mathematics and Information Engineering' ranks in the top ten globally.

Most importantly, 'Journal of Computational Mathematics and Information Engineering' not only does not charge for publication but also provides a fee to authors whose papers are accepted.

Although it's only a symbolic 100 euros per paper, having a fee is better than nothing.

"One hundred euros per paper, three papers make 300 euros!"

"300 euros, 3,000 yuan."

"If I publish three papers every week, I can earn 12,000 yuan a month, more than my salary... This is a good way to earn extra money!"
