Xu Mang was a little confused.

After all, he is an associate professor-level existence, but he can't do doctoral-level questions at the first time. It seems that he is not enough to learn mathematics thoroughly.

Some are slightly autistic,

Xu Mang became suspicious of his mathematics for the first time.

Logically speaking, if you glance at this kind of question with a glance, you will know how to solve it. However, the fact is not like this. It is not enough to glance at it. Not only that, I still don’t know the answer.

Xu Mang found a cafe on the campus of Qinghai University. He originally thought that no one came to such a place, but who knew it was full of people.

After finally grabbing a seat, Xu Mang ordered a cappuccino and asked the waiter to borrow a black pen and a few white papers, and then began to solve this doctoral-level super difficult power series convergence problem.

As we count,

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

Good guy

This is deliberately making things difficult for those doctoral students!

No wonder I have to give two days, I guess half of them are going to be unlucky for a doctorate.

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

Just like Yang Xiaoman,

At first glance, I felt that the fairy descended to the earth, but when I looked at her front, the fairy descended to the earth was in a wrong position and fell flat.

The words are rough but not rough, that's the same principle.

Something interesting!

Very challenging!

Xu Mang was inspired by this question to fight for a long time and began to solve this problem on draft paper. Since Xu Mang learned advanced mathematics, his thinking has changed. Even the mathematics problems in elementary school are accustomed to using calculus to solve problems.

The temperature of coffee is similar to that of Mr. Lu, and it is completely cold, but after so long, Xu Mang has finally reached halfway.

at this time,

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

Very ordinary appearance,

Not very beautiful. Compared to Yang Xiaoman, this girl is a passerby.

"classmate?"

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

"no."

Xu Mang shook his head and said silently: "I'm from the Milky Way."

""

"I'm so funny, you're so funny." The girl was amused and said with a smile: "My name is Zhang Ting, a sophomore in the Materials Department."

"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. This was the name they had suddenly had an idea to give the child one night. The boy was Xu Yang and the girl was Xu Aiyang.

Xu Yang?

What a strange name!

"Your name is a bit strange." 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 very strange?"

"It's not very strange. I feel it's strange at first glance, but over time I find that the name is pretty good." Zhang Ting smiled and said, "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, but was interrupted.

"Junior sister!"

"I didn't expect you to be there too."

Sudden,

A handsome young man came, and when he saw Zhang Ting, his face was filled with joy.

but,

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

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

""

"Guess?" Xu Mang suddenly became naughty and said with a smile: "Guess?"

I

After eyes confirming that he is not his competitor.

Tingting probably doesn't like this kind of mental illness.

"School girl."

"Recently I discovered some flaws in the paper "The Self-Torque of Light" by Xu Mang and Xu. I would like to discuss them separately with you." The young man said with embarrassment: "How is it?"

Xu Mang: Embarrassing

I

Brother!

Not kind anymore!

Pursuing love is the right power that everyone deserves, but what do you involve me in doing?

"ah?"

"There is no problem with Master Xu's thesis!" Zhang Ting asked curiously: "Senior, have you made a mistake?"

"Nothing wrong!"

"His calculation results are a little problem." The young man said seriously: "Of course I am not overthrowing Xu's paper, but his calculations are really flawed. Although they are innocuous, science is just pursuing perfection."

Is there any calculation problem?

It shouldn't be!

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

Xu Mang:(@_@)

""

""

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

"Junior sister?"

"Does he have an IQ problem?" the young man asked curiously: "Let's look for something else, idiots can be contagious!"

""

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

“Yes, yes!”

The young man nodded quickly.

A few seconds later,

Xu Mang came back to his senses. After his accurate calculations, he had no problems. Then he found that there were two people staring at him in front of him, namely Zhang Ting and the young man.

"What's wrong?"

"Am I too handsome?" Xu Mang showed a smile that he deserved to be beaten and said confidently: "Look at it more. I will leave in a few days, and you will never see such a handsome man again."

“???”

“???”

at this time,

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

"well?"

"You said that there are problems with computing in the paper "The Self-Torque of Light", right?" Xu Mang said with a serious look: "But I just recalled the process, but I didn't find anything wrong."

"By the way"

"My name is Xu"

Xu Mang was interrupted by this young man before he finished speaking.

"Junior sister, are you hungry? I'll treat you to dinner." The young man asked.

"Well"

"All right."

After the words,

The two left Xu Mang.

Xu Mang:???
