When Zhang Yuan gave a complete answer, Wang Lili just opened her mouth and swallowed the prepared words.
She rolled her eyes secretly and replied, "this classmate... Answered very well. Please sit down."
It turned out to be the legendary learning God. In fact, such people are the most annoying. If they don't study, they will lead to bad classroom atmosphere.
Ye Kaifu has regained his admiration in his heart. He is no longer surprised and seems numb.
"The great God is indeed a great God. He won't change the essence of the strong because of sleep..."
The strong are qualified to sleep.
He was ashamed of his jealousy.
Zhang Yuan stopped dozing off and just wandered around outside the object. The focal length of the pupil seemed to be in the distant void.
The teacher didn't call the roll again. Anyway, he read it like chanting scriptures in a class, and then it was over.
"Jingle bell", the bell rang.
Wang Lili arranged several after-school exercises to indicate that everyone can leave.
When I left, everyone was very positive. It was really frustrating.
"Come on, let's go back."
After a short sleep, Zhang Yuan was in good spirits and wanted to go back to his bedroom to continue his thesis.
Ye Kaifu reluctantly sorted out the data and asked Zhang Yuan, "the mathematical equation is too difficult. Is there a general framework for understanding?"
Zhang Yuan thought and said, "framework? Are you talking about problem solving ideas? In fact, there are not many complicated things in this course. "
"Solving homogeneous partial differential equations is the simplest. As long as separated variables are used, they can be solved according to the idea of four steps..."
"Then to the definite solution problem of non-homogeneous universal definite equation, the method is to introduce a new function, or use a method similar to the parameter variation method to treat the non-homogeneous problem as a homogeneous problem, and then use the Fourier series expansion to form a new definite solution condition..."
"Later, the treatment of non-homogeneous boundary conditions is transformed into homogeneous boundary conditions, which is transformed into the problem of solving non-homogeneous universal equations..."
"Stop!"
Ye Kaifu wanted to cry without tears and couldn't help shouting.
When he found that there was no shortcut in the whole learning process, he could only recite in his heart:
Terrible!
……
Pack up and the two are ready to leave.
"Zhang Yuan, don't go yet!"
At this time, Zhang Yuan suddenly heard a female voice calling himself behind him. He turned his head and saw that it was Xu Yunjing, a graduate student led by Professor Wang Zhong.
"Elder martial sister, are you here, too?"
Xu Yunjing said, "yes... I'm going to turn to machinery when I'm going to be a doctor, so I'll learn some relevant knowledge first, so it's convenient to change my major later."
Zhang Yuan said curiously, "transfer to engineering? Are you studying math now? Won't Professor Wang be angry? "
"No, no... he should respect my opinion."
Xu Yunjing thought: I'm not that kind of talented student. Why should I take the hard way of pure numbers? I can't make money and work hard. Can't I live with myself?
"... is he your... Younger martial brother? What a strange name you call it. " Another pair of big eyes also looked over. It was substitute teacher Wang Lili.
"Yes, let me introduce you." Xu Yunjing smiled and said, "her name is Wang Lili. She is my good friend. Now she is studying for a master's degree with Professor Lin of the school of mechanical engineering."
"Good sister!"
"The primary school brother is quite shy. I caught him wandering in class and sleeping. " Wang Lili said with a smile.
Her voice was slightly lowered: "although the problem was killed by him."
Zhang Yuan was a little embarrassed: "sister Xue, I'm really sorry. I'm tired of writing a paper, so I accidentally fell asleep. I didn't mean it. "
"So young to write a paper, what direction?"
"Using geometric group theory and topology to analyze robot motion..."
On hearing the title, Wang Lili was a little speechless: "are children so abnormal now? What about group theory and topology? I'm still worried about sending paper. Three districts and four districts are good. "
Seeing that they were exchanging greetings, ye Kaifu turned his eyes and lost his interest in being a light bulb.
He said angrily, "Zhang Yuan, I've gone to the library. Bye!"
"Bye!"
Ye Kaifu turned around smartly with a smile on his face and MMP in his heart. What "people live to learn" must be a lie.
Such a good-looking student sister hooked up in the twinkling of an eye. This technology is a model for our generation.
Since Zhang Yuan is picking up girls, we also want to pick up girls. Maybe we can meet one in the library?
There are not many holidays. We can't force it any longer.
……
After chatting for a while, Zhang Yuan asked, "elder martial sister, what can I do for you?"
Xu Yunjing patted her head: "I almost forgot. I really have something to do."
At this time, there were only three of them in the whole classroom. Xu Yunjing searched for her small bag.
She took out an invitation letter and handed it to Zhang Yuan: "in another week, the auditorium of Xisha University will hold the award ceremony of the 'Star River award' to commemorate the successful construction of the earth times. You have an important award point. Don't forget it."
Awards?
Zhang Yuan was so excited that he didn't seem to have done anything. The paper hasn't been written yet. He's just an ordinary spaceship worker. What prize will he win? For what?
"How could it be my turn?"
"It's your father's award. You think it's beautiful!"
"Oh!"
Zhang Yuan's heart jumped. It seemed that he had no right to refuse his father's award.
Xu Yunjing made an exaggerated gesture: "that's the first prize of the legendary Xinghe award, with a bonus of 10 million! As your father's only immediate relative, it's not too much for you to lead an award for him? "
"The earth age is about to start, and all these face projects will be done. And there will be a fund-raising ceremony behind it to launch those local tyrants to donate, which is the most critical. "
"The fund is short of money, not hundreds of millions, but hundreds of billions and trillions! It's also good to roll some wool from those entrepreneurs. "
"OK, OK, I see“
However, it can't be said to be a face project. It's an honor my father deserves!
Zhang Yuan thought for a while. He has donated all his possessions and has no psychological burden. Let's go.
"Shall I speak or something?" he asked
Xu Yunjing said with a smile, "just get an award on the stage. Who will pay attention to you as a pupil? Look at you! You are not a party, just a representative, and the reporter will not embarrass you. "
"It's possible for you to say a few words of 'thank you', thank the government, the foundation, the jury, etc. It's very simple. You don't have to take care of the later donation activities. We'll be responsible for it."
"That's good." Zhang Yuan hates that troublesome ceremony most. If you publish a long speech, you have to write articles. If you have time, it's not as good as a liver paper.
"Don't forget. I'll inform you again."
"I know, I know."
After talking about this, Zhang Yuan said goodbye to the two giggles, wanted to flirt with his sister, and went to think about the paper alone.
