Xu Mang was a little confused,

Anyway, it's also an associate professor-level existence, but I can't do a doctorate-level topic in the first place, it seems that mathematics has not been learned thoroughly... Business capacity is not enough.

Some are slightly autistic,

For the first time, Xu Mang had doubts about his mathematics.

Logically speaking, this kind of problem can be solved at a glance, but this is not the case, two glances are not enough, and not only that... I still don't know the answer.

Xu Mang found a café on the campus of Qing University, originally thought that no one would come to this kind of place, but who knew that it was full of people.

Finally grabbed a seat, Xu Mang ordered a cappuccino, asked the waiter to borrow a black pen and a few blank papers, and began to solve this doctoral-level ultra-difficult power series convergence problem.

Counting,

Xu Mang found that it was not his business ability that had problems, but that this professor was a wolf!

Boy...

This is a deliberate attempt to make things difficult for those doctoral students!

No wonder it takes two days to estimate that half of the PhD students will be unlucky.

In fact, this is not a simple mathematical analysis problem, it integrates many problems into it, and in the blink of an eye, it is just a power series convergence problem, but its real meaning is not this.

It's like Yang Xiaoman,

At first glance, looking at the back, it felt like the fairy was descending to earth, but looking at her front, the fairy was in an incorrect posture and fell flat.

It's not rough, that's pretty much it.

It's kind of interesting!

It's challenging!

Xu Mang was stimulated by this problem to fight for a long time, and began to solve this problem on scratch paper, since Xu Mang learned advanced mathematics, his thinking has changed, even elementary school math problems, he is used to using calculus to solve problems.

The temperature of the coffee is about the same as that of Master Lu, which is completely cool, but after such a long time, Xu Mang has only solved half of it.

At this point,

A girl sitting next to him was staring at Xu Mang.

The appearance is very ordinary,

is not very beautiful, compared with Yang Xiaoman, this girl is a passerby.

"Classmates?"

"Are you from the math department?" the girl asked curiously.

"It's not. ”

Xu Mang shook his head and said silently, "I'm from the galaxy." ”

“...”

"I... Belch... You're so funny. The girl was amused and said with a smile: "A sophomore in the Department of Materials, my name is Zhang Ting. ”

"Oh..."

"My name is Xu Yang. Xu Mang reported the name of his future son, Xu Yang was taken from the surnames of Xu Mang and Yang Xiaoman, which was the name of the child that the two of them gave to the child on a whim one night, the boy is called Xu Yang, and the girl is called Xu Aiyang.

Xu Yang?

What a strange name!

"There's something strange about your name. Zhang Ting said: "Both are surnames..."

Hearing Zhang Ting's words,

Xu Mang put down the black pen in his hand and asked cutely, "Is the name Xu Yang strange?"

"It's not very strange, I think it's strange at first, but over time I found that the name is good. Zhang Ting smiled: "Your father's surname is Xu, and your mother's surname is Yang, right?"

“...”

"Actually, my name is Xu..."Xu Mang was about to announce his name when he was interrupted.

"Senior sister!"

"I didn't think you were there. ”

suddenly

A rather handsome young man came, and after seeing Zhang Ting, his face bloomed with joy.

But

When he saw Xu Mang, his face turned from sunny to cloudy.

"Who are you?" the handsome young man was hostile to Xu Mang.

“...”

"Guess?" Xu Mang suddenly became naughty and said with a grin, "Guess what?"

I...

After eye confirmation, he was not his competitor.

Tingting shouldn't like this neuropathy.

"Schoolgirl. ”

"Recently, I discovered some flaws in Xu Mang's Xu Dashen's paper "The Self-Torque of Light"... I want to talk to you... Let's explore it separately. The young man looked embarrassed and said, "How?"

Xu Mang: Embarrassed

I...

Nabs!

It's not kind!

The pursuit of love is everyone's right, but what are you doing with me involved?

"Huh?"

"There is no problem with Xu Dashen's thesis!" Zhang Ting asked curiously, "Senior, did you make a mistake?"

"Make no mistake!"

"There was something wrong with his calculations. The young man said solemnly: "Of course, I am not overturning Xu Dashen's thesis, but his calculations are really a little flawed, although it is harmless, but science is not the pursuit of perfection." ”

Having trouble with the calculations?

It shouldn't be!

Xu Mang had copied all the processes of "The Self-Torque of Light" before, and at this time he found the copied content in his brain and began to do mental arithmetic, of course, his expression was always cute.

Xu Mang: (@_@)

“...”

“...”

Zhang Ting and the young man noticed Xu Mang's expression at this time.

"Senior sister?"

"He... Is there something wrong with his IQ?" the young man asked curiously, "Let's find another place, idiots are contagious!"

“...”

"Don't say that. Zhang Ting said solemnly: "No one who can be admitted to Qing University is an idiot!"

"Yes, yes, yes!"

The young man nodded hurriedly.

A few seconds later,

Xu Mang came back to his senses, and after his accurate calculations, he didn't have any problems, and then he found that there were two people staring at him in front of him, that is, Zhang Ting and the young man.

"What's wrong?"

"Am I too handsome?" Xu Mang showed a smile of underwhelming and said confidently: "Appreciate it more, I will leave in a few days, and you will never see such a handsome man again." ”

“？？？”

“？？？”

At this point,

Zhang Ting was a little convinced of her senior's words, this person seemed to be really abnormal.

"Huh?"

"You said that there is a problem in the calculation of the paper "Self-Torque of Light", right?" Xu Mang said with a serious face: "But just now I recalled the process, but I didn't find anything wrong. ”

"That's right..."

"My name is Xu..."

Xu Mang hadn't finished speaking, and was interrupted by the young man again.

"Senior sister, are you hungry? The young man asked.

"Uh..."

"Okay. ”

Words fall,

The two of them left Xu Mang.

Xu Mang: ???

This...

Let's go?

I didn't even say my name!

At this time, Xu Mang was very angry and wanted to catch up with the two and tell them that he was the legendary Xu Dashen, but the disaster was not alone, Xu Mang received a call from Yang Xiaoman.

"Stupid!"

"Where did you die?" Yang Xiaoman scolded angrily: "Our opening ceremony is over, and I've been looking for you for a long time!"

"Oh..."

"I'm at the Xueba Cafe at Tsinghua University. Xu Mang said: "Come here alone, don't call them over, the coffee here is quite expensive." ”

“...”

"Slam the door!"

soon

Yang Xiaoman came to Xu Mang's side, glanced at the coffee he didn't drink on the table, and asked curiously, "Since you don't like coffee, why do you still order it?"

"I was stumped by the PhD-level topic. Xu Mang said helplessly: "Just find a place to do the question." ”

"Question?"

"What did you do when I went to the opening ceremony?" asked Yang Xiaoman with a strange expression.

"I went to the Mathematics Department of Qingdao University to get a feel for the teaching methods of the University. Xu Mang said: "Although I am a senior mathematics lecturer in the Department of Physics, my salary is that of an associate professor, in order to provide students with excellent teaching quality, what happened to me to listen to the class?"

"Do you have an opinion?"

"Do you dare to have an opinion?"

"Can you be interesting?"

When Xu Mang said this, Tianling Gai was a little stiff and said, "Please answer me!"

Yang Xiaoman is so angry, he must win the first place this time, otherwise this guy will go to the house to reveal the tiles!

"Boom!"

"Go on!" Yang Xiaoman said with a dark face: "Think about what to do at night!"

Oops!

I forgot!

Stayed in a room with Xiao Man in the evening.

Xu Mang smiled awkwardly, silently held Xiao Man's hand, and said with a smile: "Don't be like this... Ten years of repairing the same boat, and a hundred years of repairing sleeping together... Give me a way to live. ”

"Humph!"

"Then it depends on your performance!" Yang Xiaoman said proudly.

Xu Mang nodded vigorously.

afterwards

The two returned to the hotel, had a little lunch, and Xu Mang locked himself in the room.

however

When Xu Mang was about to finish the calculation, he found that the professor had set a trap at the end.

The depth of the routine is overwhelming!

No way

According to the obtained conditions, a model is made, and the model is used to solve it.

But...

Xiao Man didn't bring a computer.

"Bang bang bang!"

"Old Man Lu!" Xu Meng knocked on the door of Lu Wei's room.

"Xu Mang!"

"Please call me Lu Wei, and I'm not old at all!" Lu Wei said seriously.

Xu Mang smiled: "Anyway, they are all philanthropists, and they are all the same in essence, do you bring a notebook?"

"Yes!"

"MATLAB, SPSS, and LINGO?"

"Of course!"

"Lend me a little bit. Xu Mang said: "I calculate a problem. ”

"Oh..."

After Xu Mang got the notebook, he began the intense and interesting modeling process.

night

Always come that fast.

The two of them whispered something that could only be said in the dark of night.

"Huh?"

"Don't slip away tomorrow. Yang Xiaoman glanced at Xu Mang and said viciously: "Otherwise... You get the idea!"

"Understood!"

"I've just been taught. Xu Mang hugged Xiao Man's shoulder and said cautiously.

Followed by

The two frantically sprinkled dog food, but there was always a Chu River between the handsome generals.

Following

Xu Mang, as the leading teacher, followed Yang Xiaoman and a few people to the game site, the first game was a personal competition, at this time there were still 20 minutes before the start of the game, and the players entered.

The world is impermanent,

Life is full of unimaginable accidents.

Xu Mang looked at the players in the arena and felt extremely emotional.

I used to sit in it,

Now sit outside by yourself.

The next thing has nothing to do with Xu Mang, but he is a person who can't sit still and begins to wander around the sidelines.

Alas?

Zhejiang Provincial Team!

As a native of Zhejiang Province, Xu Mang was very kind when he saw his fellow countrymen, and walked over with a smile.

"Teacher?"

"You're from Zhejiang Province?" Xu asked.

"Are you?" the middle-aged man asked.

"I'm a student of the Modu team. Xu Mang said with a smile: "Actually, I am from Ning City, Zhejiang Province. ”

"Oh!"

"Fellow!" The middle-aged man's favorability towards Xu Mang instantly increased: "I am also from Ningshi!"

Xu Mang was stunned for a moment: "Fate!"

The two sat together and started chatting, chatting and chatting was wrong, the teacher of the Zhejiang provincial team felt... It feels like this young man is bragging about himself all the time.

"I'll tell you... This game is really not interesting, it is too simple. ”

"I'll take the first place casually!"

"And it can all be solved in half an hour!"

"Really!"

The teacher of the Zhejiang provincial team said helplessly: "This classmate... I don't think you're very old, and your tone is a little small. ”

"Actually, I..."

Xu Mang was about to say that he was a great genius Xu Mang, but he was interrupted by the ringtone of his mobile phone.

Mail!

And it's also an email reply from Nature.

took out his mobile phone, clicked on the email, Xu Mang glanced at it, the content was very simple, probably to congratulate his paper "On the Superconductivity Possibility of Lanthanum Hydride" was selected for the next issue of Nature.

"I'm sorry to miss me. Xu Mang said sincerely: "My paper has been selected for the next issue of Nature, and I will inform the university." ”

Teacher of Zhejiang Provincial Team: ???
