Wang Hao worked for another half an hour and felt exhausted, so he simply stopped to rest.
Put on your shoes and go out.
Go to the community and its surroundings to relax and get acquainted with the surrounding environment.
The environment near the community is very good.
It is adjacent to Xihai University on the east side, and there is a small park on the north side. Going around the small park is a hospital, and then turning back is a spacious commercial street.
Walking into the commercial street, there is a fast food restaurant on the corner.
Wang Hao touched his stomach and felt a little hungry, so he simply went into a fast food restaurant, ordered a hamburger set and sat down to eat.
The fast food restaurant is doing very well, with people coming and going.
While I was focusing on destroying the food, I heard a cheerful voice asking, "Handsome guy, is there anyone here?"
Wang Hao raised his head and found that he looked familiar.
Opposite door?
The skinny girl seems to be called "Youyou", the fat girl is called... what?
I couldn't remember it for a while.
Li Qian quickly recognized Wang Hao, with a little vigilance in her eyes. She looked around, pulled Gu Youyou to sit down, and asked pretending not to care, "It's the opposite door. Let's sit here without disturbing you, right?"
"……It doesn't matter."
Wang Hao looked at the two girls carefully and thought about it for a long time. He couldn't remember what they were called, so he simply continued to destroy the food.
The two girls kept looking at Wang Hao.
That look made Wang Hao feel awkward and strange.
What is this for?
Li Qian and Gu Youyou looked at each other, and finally she asked, "We live across the street and are neighbors. I still don't know your name?"
"Wang Hao."
Wang Hao said while eating.
"You rent a house by yourself, it's more than two thousand, you should be working, right?"
"Um."
"What work?"
"teacher."
Wang Hao ate the last bite of his burger before finally raising his head and asked, "Checking household registration?"
"no no!"
Li Qian was shocked and a little embarrassed, "I just want to know more about it."
Suddenly, it was quiet.
The two girls observed Wang Hao carefully for a long time. Gu Youyou finally couldn't hold it in anymore and asked directly, "I said it in the elevator last time. How do you know our rent?"
Wang Hao thought for a moment and said doubtfully, "I don't know? Last time I just said that my rent was more expensive than yours. What's wrong?"
The two girls quickly communicated with their eyes.
Gu Youyou took a breath and thought about it carefully. The other party really only said "five hundred more expensive". Maybe five hundred is not a definite value, but just a valuation number, which is equivalent to "a few hundred more expensive"?
Is she overthinking it?
After taking a closer look at the boy opposite, he saw that he was very polite and didn't look like a bad guy, so he finally gave Li Qian a "safe" look with confidence.
Li Qian pursed her lips hard and immediately started scrolling through her phone.
Gu Youyou took out her book and read it intently. She was thinking about a topic. She tapped her forehead hard with the tip of her pen and said to Li Qian worriedly, "Have you thought about this homework question?"
Li Qian turned her head and glanced at it, then said nonchalantly, "Give up."
"I knew it."
Gu Youyou covered her forehead helplessly.
Li Qian sighed, "I gave up a long time ago. I regret it now. When I took the college entrance examination, I shouldn't have applied for the Department of Mathematics; if I didn't apply for the Department of Mathematics, I wouldn't have studied for a graduate degree in applied mathematics; if I hadn't studied for a graduate degree in applied mathematics
As a graduate student, you won’t encounter these complicated questions.”
Wang Hao was about to get up and leave. After hearing this, he immediately sat back and asked, "Are you majoring in mathematics?"
"What's wrong?"
The two girls looked over.
Wang Hao was indeed a little surprised. In his memory, the number of female graduate students in mathematics at the same level at Donggang University was pitifully small, and it was even less likely that there would be any who were beautiful. They could not be described as 'rare'.
At the doctoral level, girls have disappeared.
He gave a thumbs up and said, "Awesome! Girls studying mathematics are rare."
"Let me see!"
He glanced at the topic on the table with curiosity and immediately understood, "C[a,b] is an incomplete distance space in the sense of integral average convergence..."
"This is easy!"
He took the pen and paper and explained while analyzing, "This is a classic functional analysis question. You must first set the value range of the Xn(t) column. The value of n is a natural number..."
"Looking at these three columns, it is obvious that {Xn} is included in C[a,b]."
"For n greater than m, d(Xn,Xm) is equal to..."
"If {Xn} converges within the range of this column, it can be proved that there is X(t)..."
"..."
"..."
"It follows that C(a,b) is incomplete in the sense of convergence of integral averages."
After Wang Hao finished speaking, he looked at it carefully and found that there was indeed nothing wrong with it. He nodded with satisfaction.
Postgraduate level mathematics problems are indeed a piece of cake for him.
Gu Youyou and Li Qian were stunned on the spot.
They followed the train of thought and listened carefully, feeling their scalps numb and unable to get around something.
However, the other party solved it very easily. He didn't even have time to think about it. It was as simple as copying the answer.
This is a professional question for graduate students in mathematics!
Gu Youyou looked at Wang Hao seriously and suddenly asked again, "What did you do for a living?"
"Teacher?"
"teacher?"
Wang Hao nodded slightly, pointed to the dining table and said, "Your number is here, go get your meal."
"I go first."
With that said, he stood up and walked out the door.
Li Qian was busy bringing food back and saw Gu Youyou thinking, "What's wrong?"
"I was thinking about what just happened."
"He's so awesome!"
Li Qian couldn't help but admire, "I gave up on that question as soon as I saw it, but he actually wrote the answer directly."
"Don't you think it's weird?"
"What's weird?"
Gu Youyou clicked her fingers, as if she were transformed into Sherlock Holmes, and analyzed it carefully, "That question is difficult. The teacher said it, just try to think about it. There is no requirement to get it right."
"But he knew the answer just by looking at it, as if he had done it before."
"Even if you have done it, you still have to think about it, right?"
"And he is a teacher. Even if he has a master's degree, he happens to major in mathematics? And he happens to be able to solve this problem?"
Li Qian nodded along with the train of thought, and then said nonchalantly, "What other reasons could there be? Could it be that he specifically investigated us, even went so far as to investigate our homework, and conducted research in advance... He didn't even make up a story like this."
"Besides, what's the point of putting so much effort into it?"
Gu Youyou frowned and thought.
Li Qian rolled her eyes, came over and joked, "He is polite and polite. He doesn't look like a bad person. He didn't look like he was lying just now. His lecture was also very professional. If he is really investigating us, maybe... he wants to chase you?"
"Yuyou, your charm is too great, think about it!"
Gu Youyou's face turned red and she hurriedly said, "What nonsense are you talking about? How can you fall in love with me when you meet a boy? Why bother to put so much effort into it? It's really meaningless. I will definitely not fall in love before graduation."
"Cut~~~"
Li Qian said sourly, "If a boy really puts so much thought into chasing me, he can get married where he is!"
"Is it okay to have a wedding in the same place?"
"Go to hell!"
…
The next day there was still class at 10 am.
Because I have the experience of one class, I don’t need to prepare lessons again.
Wang Hao arrived at school at around nine o'clock and went directly to the classroom where the class was held. Because three classes were in class together, the number of students was slightly more than yesterday.
It’s the same introduction, it’s the same request.
He walked through the process with ease and reminded all students that they must listen carefully to every lesson.
Then, the course begins.
This time, a teaching coin was used to promote the acquisition of inspiration value for research and development related to 'Fourier Transform'.
Wang Hao felt that the course was progressing more smoothly, and he was still continuously acquiring knowledge content in his mind, but compared to yesterday's situation, it was much worse.
Halfway through the course, he checked the progress of the task and found that the inspiration value had only increased by '31' points.
"This number is definitely not as good as yesterday."
"It should be a duplicate problem. There must be an upper limit to a single research, or in other words, if many students have the same idea, it will not bring new inspiration."
"But an increase of dozens of points is quite a lot..."
The applied research on ‘Fourier Transform’ has a continuously increasing inspiration value, while the research on ‘Analysis of Partial Differential Equations’ has a very poor inspiration value.
It has only increased by '5' points until now.
"It's probably related to the difficulty of research and development and its relevance."
"It's about Fourier transform, and the inspiration value grows relatively fast. The analysis of partial differential equations is basic research, and the difficulty rating is 'B'. Fourier transform is just a method of solving partial differential equations."
Wang Hao thought carefully and understood.
He continued to be immersed in the course, constantly interacting with students, and interspersing some incidental knowledge to make the course content rich and interesting.
Those students who listened carefully to the lecture felt that Wang Hao's lectures were very good, even better than the original "Mr. Li".
Those students who don’t listen to the class...
Three of them were called up and made to stand, and one was half an hour late, so he was simply considered absent from class and had his name written down.
…
noon.
After Wang Hao had lunch, he returned to the office to work. He had almost summarized the application expansion and algorithm expansion related to Fourier transform.
He plans to split the content into three papers and publish them.
One part is the application research of Fourier transform, which is related to the content of solving partial differential equations and focuses on discussion and thinking.
The other two parts are Fourier transform-assisted construction of data models and applied to algorithm research for data analysis.
There is a lot of content in the latter part, and if it is streamlined, the total will exceed thirty pages. It is not easy to submit a manuscript and publish it in one go.
Because of this, it will be published in two parts.
In the afternoon, Wang Hao worked continuously for more than three hours, and then took a cup of coffee and took a break.
The main body of the paper has almost been written.
The remaining work is to polish it, modify the format of the paper, and then find an academic journal to submit it to.
He also studied the issue of submission.
The Faculty of Science of Sokai University has a cooperative academic journal, and it can be published directly after it passes the on-campus editorial review.
However, the academic journals we cooperate with have very low ratings, barely reaching the 'recognized' level, and are not influential in the academic field.
Influential domestic magazines all need to pay a high fee to publish.
Wang Hao decided to submit the article to a foreign magazine - "Computer Mathematics and Information Engineering".
"Computer Mathematics and Information Engineering" is a professional mathematics and computer academic journal that focuses on publishing research content in the fields of data architecture, algorithms, and information communication.
In the fields of computer mathematics and algorithms, the influence of "Computer Mathematics and Information Engineering" ranks among the top ten in the world.
The most important thing is that when "Computer Mathematics and Information Engineering" publishes papers, it not only charges no fees but also provides royalties to authors who have submitted manuscripts.
Although it is only a symbolic 100 euros per article, it is better to have royalties than nothing.
"One article is 100 euros, three articles is 300 euros!"
"Three hundred euros, three thousand yuan."
"If you publish three papers every week, you can earn an extra 12,000 yuan a month, which is higher than your salary... This is also a good way to make extra money!"
