Little sister, I'm a little busy right now, so I'll get back to you tonight!
Chen Nuo hung up the phone, glared fiercely at the student who said he had kidney deficiency, collapsed five steps in one step, and disappeared from everyone's sight in an instant.
Heh, is this the kidney deficiency you mentioned?
With seven or eight takeaways in hand, Chen Nuo became a windy boy, shuttling around the library.
Outside the door of No. 3 research room on the fifth floor, boom!boom
Hello, your takeaway has arrived!
The door is unlocked, send it in!
A crisp female voice came from the room, Chen Nuo pushed the door open and entered.
Hey, in the research room, there are seven or eight students, five girls, and three boys, all gathered around a few whiteboards, discussing in low voices.
Hello, your takeaway has arrived, I wish you a happy meal!
Chen Nuo put the takeaway on the table, glanced at the whiteboard inadvertently, it turned out to be a math problem, and immediately became interested.
Just got a college professor-level mathematics, just to verify it.
Set a two-bit random variable f (X, Y) to find the constant A and the conditional probability density
This is a probability density calculation problem for a normal distribution.
A few whiteboards are the answers of several students, but the answers are slightly sad.
Chen Nuo watched and shook his head, his train of thought was wrong, let alone the next steps.
One of the boys saw his actions, and he didn't wrinkle immediately.
Food delivery, what do you mean by shaking your head?Do you have opinions on us, or on the problems we solved?
Nothing, my neck is sore, I wish you a pleasant meal, goodbye!
Chen Nuo didn't want to make trouble, so he turned around and walked towards the door. With this skill, he might as well run two more takeaway orders to improve his skills.
stop!If you don't speak clearly, you are not allowed to leave. If you dare to leave, I will give you a bad review!
The girl who ordered takeaway raised her eyebrows and said, "Wang Sen, is there something wrong with you? The takeaway boy just shook his head. Are you in charge?"
That is, what is food delivery? Can you sit here and eat comfortably without a delivery boy?Don't look down on people.
Also, it’s Xinran who orders takeaway, and it’s Xinran who wants to comment. What are you?
All the girls directly turned to Wang Sen.
Brother, don't take it to heart, they didn't mean it either, we have been tortured by this question for several days, and the instructor will come to check in a while, we are also in a hurry, I apologize to you on behalf of them!
It was the girl on the phone who spoke, her voice was still so crisp.
Chen Nuo glanced at her, and his eyes lit up immediately. He was tall and tall, with fair complexion, soft hair, clear eyes, and looked familiar, but he couldn't remember where he saw her.
What to see, hurry up, you can't stay here!
Seeing Chen Nuo's changing eyes, Wang Sen became angry immediately.
Chen Nuo also lost his temper. Ren Shan was bullied by others, and he didn't say a word. Instead, he was ridiculed by these boys, making him look inferior.
Didn't you ask me why I shook my head?Then let me tell you, your problem-solving ideas are wrong.
The room was quiet for a while, and then several boys laughed loudly, as if they heard a big joke.
Several girls also opened their mouths wide, not knowing what to say.
What did you say?Are we thinking wrong?You tell me again?
I don't even know that food delivery people are so loud now?Do you think you are Will in the catcher of your heart, or Wei Rufeng in Blooming Pinellia?
Come here, I'll give you the pen, if you can solve it, I'll eat this pen!
The three boys taunted Chen Nuo again.
Chen Nuo didn't say a word, just stepped forward, picked up a whiteboard marker and started writing on a whiteboard.
If he can solve it, I will immediately quit this group!
To shut up!
The beauty let out a low drink and stared intently at the whiteboard.
Characters appear one by one, and the writing is smooth and flowing.
Ten minutes later, after writing on three whiteboards, Chen Nuo put down the whiteboard marker, took a step back, and read it from beginning to end.
Well, yes, the handwriting is generous, the logic is clear, and the conclusion is correct. The overall score is [-]. The only dissatisfaction is that there are too few whiteboards, and a few steps are omitted.
Chen Nuo turned to look at the three boys, and said calmly: Do you understand?
Shall I tell you all about it?
Forget it, with the IQs of the three of you, I probably wouldn't understand it!
Chapter 6 Rising Mathematical Stars
Hello, my name is Ye Xin
Not interested, the takeaway is getting cold, hurry up and eat, never see you again!
Chen Nuo directly interrupted the beauty, turned around and left the door.
He knew what the beautiful woman wanted to say, she just wanted to see his good looks. Well, no, I asked him to explain it.
A woman will only affect him to become the most beautiful boy.
In the research room, Ye Xinran gritted her silver teeth angrily, and said angrily: Straight man!
In the research room, the three boys saw this scene, their eyes were about to spit fire.
Ye Xinran is Huaqing University's top beauty student. Not only is she beautiful, but she is also a top student in college. In the four years of college, she has never seen her flirting with any man.
Now how could they not be angry at a food delivery boy who acted like a little girl.
Bang!The door opened again.
Chen Nuo leaned halfway in, and said: I forgot one thing, I remember you three said that if I figured it out, you would quit this research group, right?
Seeing that it was Chen Nuo, Ye Xinran was about to speak again, when Chen Nuo said: "Beauty, I have solved a problem for you, don't thank me, please call me Lei Feng!"
Then it disappeared at an extremely fast speed.
In the research room, the five girls stared at the three boys together, their meaningful eyes made the three feel like they were sitting on pins and needles.
What to look at, I mean if he solves it, I will quit, but you look at what is written here.
That's right, look at the eighth and ninth steps, the preface is inconsistent, and there is No.13 step, how is the result calculated?
As for the last step, it's hard to say whether the result is right or not.
The three boys were originally competitors, but at this moment they were fighting against each other, standing firmly together.
The reason why they joined this research group is that they want to get close to Ye Xinran, so that they can get the moon first.
Throwing out the characters of the three of them, in fact, the three of them have a good foundation in mathematics, and they can understand that there is a problem with the few steps that Chen Nuo omitted.
Not only the three of them, but also the five girls. Although they don't understand it very well, based on their intuition, the process and answer should be correct.
I have to say that people's intuition is sometimes terrifyingly accurate.
Alright, don't discuss it yet, hurry up and eat, and it will be clear when the professor comes and asks!
When Ye Xinran said this, he glanced at the three boys, the meaning couldn't be more obvious.
Half an hour later, a middle-aged man with thinning hair and ordinary clothes walked into the research room.
This person's name is Zhao Yuan, and despite his unremarkable appearance, he is well-known in the Huaqing Department of Mathematics and the entire Chinese mathematics community.
do it
Professor Zhao Yuan was stunned when he saw the three whiteboards written by Chen Nuo in the middle of his speech.
Then he walked quickly to the whiteboard and read line by line. The more he looked, the more excited he became, and the more he looked, the more shocked he became.
The three boys saw the professor's expression in their eyes, and gradually felt something was wrong.
wonderful, really good
Well, it can still be written like this here, good idea.
After 10 minutes, Professor Zhao Yuan finally finished reading it, and he was amazed.
This question is not particularly difficult, but it is definitely not something these senior students can do.
He gave this question to a few students to test their thinking and see how talented they are. He didn't expect the surprise to come so suddenly.
Professor, is this process and result completely correct?
Ye Xinran asked in a low voice.
You don’t even understand what you do yourself?When Professor Zhao Yuan said this, he suddenly froze.
The handwriting on the whiteboard was not any of the eight of them, and this method even surprised him, let alone these few students.
Zhang Taixue is here, or Sun Ming is here, or Li Qiuhong is here, and some old things come to smash my place!
Every time Zhao Yuan said a name, several students trembled, and these people were all professors from the Department of Mathematics of Huaqing.
Neither Zhao nor Professor Zhao, this question was made by a delivery boy.
Seeing Professor Zhao Yuan's serious gaze, Ye Xinran dared not look directly.
Impossible, I am glad you are taking this joke a little too far!
Professor, it's true, if you don't believe me, ask them.
Ye Xinran pointed to the students next to him, and they all nodded in unison.
What's going on, tell me clearly!
Zhao Yuan's tone was very heavy, he was really angry.
Ye Xinran told the whole story without any embellishment, it was completely straightforward.
After Zhao Yuan heard this, he gave the three boys a hard look, and the hearts of the three were shattered.
No, you just said he only took 10 minutes?
Yes, he read the question once, and then wrote it in 10 minutes. He didn't even type a draft in the middle, and it was done in one go!
Zhao Yuanru was struck by lightning.
It was finished in 10 minutes without even a draft, and it took him 10 minutes to understand the process.
In addition to being older and less agile in thinking, Chen Nuo's level has completely surpassed him.
Professor, are you all right?
Everyone looked at Zhao Yuan a little sluggish, with worries on their faces.
Zhao Yuan took a deep breath, suppressed the trauma in his heart, and said in a hoarse voice: "What's his name?"
Everyone looked at Ye Xinran, then shook their heads in unison.
Why are you still standing there, find it for me, you must find it for me!
Zhao Yuan shouted angrily, his voice gritted his teeth.
The three looked at the angry Zhao Yuan, smiled gloatingly, and then hurriedly said: Professor, don't worry, as long as he delivers food near Huaqing, I will find him for him, and if he dares to smash our place, I will definitely replace him. You teach him a lesson!
teach him a lesson?
Zhao Yuan was stunned for a moment, then slammed the table, his voice suddenly raised an octave, and said: Who said I was going to teach him a lesson?are you a pig?That little brother is extremely gifted in mathematics, even your brother Cheng Yong can't keep up with him, how can I teach him a lesson?
I asked him to come to read my graduate degree, no, my Ph.D.
Guaranteed exemption!
Everyone was stunned when they heard Zhao Yuan's words. Who in the entire Huaqing Mathematics Department did not know that Zhao Yuan's graduate and doctoral exams were the most difficult.
Now even let a takeaway brother go directly to his Ph.D., and he is still recommended to be exempted from the exam.
Besides, who is Cheng Yong?That's a big deal. Although he hasn't graduated with a Ph.D., he has published five extremely well-known papers. Is the delivery boy better than Senior Brother Cheng?
This subverts their three views.
