Chapter 408: Amazing speed (two/three)

"What did you just say?" The cousin looked at her husband, with an incredible expression on her face: "Quickly retell all what you just said, tell me again without missing a word!"
"what?"
"This... it's very difficult." The cousin said helplessly: "Anyway, it's the mistake you just pointed out. Xiao Xu pointed it out for me two hours ago. At that time, neither of us took it seriously. Until...just now."
I...
This...
how could it be possible? !
Xiaoman's fiancé, Xiao Xu, is actually so talented in mathematics?
If what your husband said was not deceiving, then Xiao Xu probably already solved the problem he posed in the afternoon. Perhaps for some reason, he didn’t want to spend it on that topic. Too much time.
Cousin Xiaoman is very helpless, if her own ideas are established, this Xiao Xu is simply terrible.
Before that, I have read many papers by Xiao Xu. Although it involves a lot of mathematics, I thought it was someone in the team who specialized in solving mathematical problems. But now it seems that Xiao Xu is the one who solves mathematical problems. .
"You didn't lie to me?" Xiaoman's cousin asked.
"No!"
"At that time, I was giving a lecture to Xiao Xu, and he was sitting next to me and he was attentive. After I finished all the lectures, he pointed out my mistake on the spot, and then you showed up, and the next thing happened." The cousin said: "As time goes on, I am talking to you now."
"..."
For her husband’s narration, cousin Xiaoman has long been accustomed to it. At this time, her self-esteem was hurt, and the victim was her cousin’s fiancé, the mathematics professor of cousin, and she lost to the physics professor of Fuda. , Still in the field of mathematics.
It is not to belittle Fuda, but to lose to amateurs in his professional field.
"How many times have you talked?" the cousin asked hurriedly.
"Once again!"
"Are you sure it's once?" the cousin said incredulously: "Not three times? Not five times?"
"Just again." The cousin said seriously: "I will never lie on this."
Again...
Heart hurts!
As a professional mathematics professor, I read it carefully twice before finding the error.
at this time,
The cousin's husband saw his wife, shocked from the beginning to now dissatisfied, and carefully asked: "My wife...you have something wrong with this expression, did you get along with Xiao Xu? I found that I was not as good as Xiao Xu. , Don't be like this... people are guests."
original,
There was nothing big, but I was so angry with my husband that he instantly became angry and said angrily: "He is a physics man who wants to crush me in the field of mathematics? You are also highly educated. Do you think it is in line with science? ?"
"No..."
"I'm just a doctor, so I won't be involved in the battle between your professors." The cousin said helplessly, "I'm innocent...whatever you love, don't hurt your peace anyway. , After all, they are all relatives."
"I know!"
"You sleep your sleep." The cousin glared at her husband and sat on the bed silently thinking about something.
...
The next day,
Xu Mang and Xiaoman are holding each other to death. There is no way... They both suffer from a terminal illness, "If you don’t hold each other, you will die syndrome." Hold, otherwise it will be difficult to fall asleep, of course it doesn't matter when you are alone.
Suddenly the door was opened, and a dark figure rushed in. The dark figure turned on the light. This person was Xiaoman's cousin.
"..."
"These two people... is it necessary to be so affectionate?" The cousin saw the two holding each other, her face was covered with black lines, thinking of her cousin's so pure and lovely girl, she actually degenerate into this way, the power of love. .. It's too scary to imagine.
"Don't sleep!"
"Get up and get up!" the cousin shouted.
moment,
The two looked at their cousin with a bewildered face, not knowing what happened for a while.
"You slept so late in China?" The cousin looked at the two people who looked at a loss, and said helplessly: "I remember you are going back tomorrow, right? Uh... I'll take you around New York again."
"..."
"..."
Yang Xiaoman was not a sleepy person before, but after playing with Xu Mang, he gradually became infected with some of his bad habits and likes to sleep very much.
"sister!"
"We don't want to go anywhere, we just want to sleep all morning, eat and drink and play in the afternoon, and then get on the plane to go home." Yang Xiaoman twisted his face, angry but afraid to send, said: " Sister...Don't disturb the two of us sleeping."
How could cousin Xiaoman let the two of them continue to sleep? Today, she deliberately asked for leave from the school in order to implement the plan she thought of last night.
soon,
Yang Xiaoman and Xu Mang were angry, sitting in the living room and eating breakfast, toast bread, jam, omelette, milk, this kind of western breakfast made Xu Mang unbearable, and he did not like sweets.
"cousin?"
"Is there any national goddess hot sauce?" Xu Mang asked: "It's called TheGodmother in English."
"No!"
"Do you like to eat or not." Xiaoman's cousin said blankly.
Ugh...
I don’t even have the national goddess hot sauce. How do I have this breakfast?
Xu Mang ended up with a fried egg sandwiched between two slices of toast, smeared with a layer of mustard, and ate it with tears.
"Xu Mang?"
"I still don't believe what you said yesterday." The cousin smeared strawberry jam on the bread, and said blankly: "You said that you unwrapped it at the time. This is not willing to spend too much time on it... . Isn't that the same thing?"
"Yes!"
"I think that topic is not difficult at all, but its process is extremely complicated." Xu Mang said indifferently.
Xu Mang was not nonsense. Yesterday, when he finished the meal, he analyzed the speed of the subject, and finally thought that it would take about 20 minutes to turn on the beast mode, while the average person needs at least one and a half hours.
period,
You can't make a mistake. If any small detail is wrong, you must recalculate.
This question examines students' patience and insight.
Although Xiaoman's cousin believed Xu Mang's words, she still pretended to be disdainful and said to Xu Mang: "You guys brag, I'm very surprised why Xiaoman would like you so much. Braggart."
"..."
"Sister...Xu Mang is really amazing." Yang Xiaoman fought weakly, but her resistance was useless.
quickly,
After breakfast was finished, Xiaoman's cousin took the two and left her home.
But I feel something is wrong when I go shopping.
Why did you come to Columbia University?
"Xu Mang!"
"Currently you have two choices." Xiaoman's cousin said solemnly: "Walking with our two sisters, or you can stay at Columbia alone and solve my problem."
Xu Mang: Σ(｀д′ノ)ノ
Damn it!
It's a great effort.
Two evils take the lesser... Xu Mang chooses to understand the problem.
Shopping,
Just kidding...Every time I go shopping with Xiaoman, I almost never die, and now there is one more cousin of her, which is not more tragic.
"Go slow!"
Looking at the backs of the two sisters leaving, Xu Mang felt a little lonely for a while. In the past, he was not a person who was afraid of loneliness, but after being with Xiaoman for a long time, he gradually became unaccustomed to being alone.
"Unexpectedly, the influence of this short flat and flat is so great." Xu Mang sighed and looked back to the huge blackboard. One blackboard could not cover the problem-solving process. Xu Mang noticed that he had prepared two More than ten blackboards can be moved up and down, left and right.
"System... Turn on the beast mode!"
[Activate the beast mode]
Open!
Xu Mang picked up the chalk beside him and frantically scribbled on the blackboard.
Swish,
The speed is outrageous.
ten minutes later,
It was just time for class. The students were holding their books. When passing by Xu Mang, almost everyone stopped involuntarily and looked at him with a confused expression.
With their backs to the crowd, the students did not know that Xu Mang was solving the problem.
However, most of them just joined in the fun and left after standing for a while, but those students of mathematics, physics and chemistry became a bit hideous.
"Bob...this...do you know this guy?"
"do not know!"
"I don't know who he is... but he is so powerful, he solves the problem so fast, I just don't know if he is right."
"There seems to be no problem at the moment."
The crowd began to talk, and most of them were guessing who this guy was, but because of the upcoming class, the students did not stay long and left behind Xu Mang.
soon,
In the multimedia classroom for mathematics,
These first-year undergraduates of Columbia University were discussing what was just now. There is a mysterious man trying to solve the problem that is extremely complicated and takes a lot of time. However, his speed is so fast that it cannot be explained by science. .
At this time,
An old white-haired man came to the classroom. He is the math professor who is teaching today.
"Professor Angus!"
"Did you notice anything unusual on the way?" A girl raised her hand and asked the old professor: "Did you notice a boy?"
Strange?
Boy?
what's the situation?
The professor said curiously: "I came from another channel, and I didn't notice what you said was strange or a certain boy."
"Professor Angus!"
"Professor Mu's problem in applied mathematics seems to have been solved by someone. I took a video!" The girl took out her phone and clicked on a video she had taken.
Professor Angus walked to the girl’s side and looked at the back of a boy on the screen of the phone. He was now holding a chalk and scribbling crazy on the blackboard, but... it’s not a graffiti. If you look closely, you can see that he Is answering the question.
Strange...
Can his brain keep up with his hand speed?
Scribbled?
Professor Angus knows that the difficulty of this topic is not particularly difficult, but the process is extremely complicated and requires amazing patience and strong insight. However, from the video, it is likely to be messing up. UU Reading www. uukanshu. Com answers are given directly without thinking, how is it possible.
This is too unscience!
"Go and see if that student is still there." Professor Angus said to the girl.
"Good professor."
Words fall,
The girl hurried out of the classroom.
"All right."
"Now we start class."
Professor Angus returned to the podium and just turned on the computer. At this moment, the girl ran to the door of the classroom, panting heavily.
"professor!"
"I think...you...you'd better go see it yourself!" The girl said breathlessly, "It's so shocking!"
