Chapter 342: Mom advises you to surrender early (1/3)

Eight and a half hours,
Can you write so much content in an overnight time?
And... it seems to have written all the content of quantum mechanics needed. For example, this first-principles calculation involves a total of five principles, but all of them are written, and the content is horribly detailed.
Such as this density functional theory, even the three students from the Department of Physics and the Department of Chemistry had a chill on their backs when they saw it.
Wrong!
Shouldn't Teacher Xu be happy last night?
Is he working while being happy?
Are you crazy?
The five people looked at Xu Mang who was lying on the wire bed at the same time, and saw him playing with his mobile phone comfortably, and laughed from time to time. The ghost knew what he was looking at, but he was very happy now.
This...
This is simply subverting the outlook on life.
"Tutor Xu?"
"Have you filled all quantum mechanics in?" Zhang Xu asked with a shocked look: "One night?"
"Yes indeed."
"You are left to help me. The content of heat, electricity, magnetism and optics, you derived from quantum mechanics." Xu Mang said nonchalantly: "I will check it after finishing it, and if it is almost appropriate, I will proofread it. Click, and finally establish a system to connect with the old database."
Words fall,
There was no sound in the laboratory, mainly because of the terrifying speed.
It's not human...
"correct!"
"I checked your research results during the day last night, and then made a note. You can take a look at the wrong place and do it again." Xu Mang put away the phone, stretched his waist, and got up in silence to go to the bathroom.
"???"
"???"
"???"
Ugh?
what's the situation?
How can I walk around?
"Xu...Tutor Xu?" Lin Wanwan asked in horror: "You...you don't need a wheelchair?"
"I just got caught in my waist, and it's not a powdery fracture." Xu Mang said with a black face, "I am in a wheelchair because I am afraid of the recurrence of the old injury. Now I want to move around and dredge the blood vessels. Do you know medicine?"
"..."
Lin Wanwan didn't want to talk, just wanted to smash a brick on Xu Mang's head.
When Xu Mang left,
The five people looked at Xu Mang’s remarks last night. At this time, the few people didn’t want to be too shocked. They always felt that these were normal. After all, Xu Mang Xu could not think about his various behaviors with normal human thinking. .
but...
His knowledge reserve is really rich, and he can't think of a person's brain that can hold so many things.
After processing yesterday's research results, several people read back to the framework of quantum mechanics. Xu Mang did not blindly move everything in, but chose to move content that is closely related to materials.
And these theories can almost derive other disciplines, and those disciplines correspond to materials science.
"Too awesome!"
"I just discovered the relativistic density functional theory...you can directly derive the properties of heavy element compounds from it. This is already a chemistry discipline." Zhou Mengdi said with a look of admiration: "Wait for him to come back, I want Ask carefully."
"Ugh?"
"What's the situation?" Xu Mang returned to the laboratory and saw that the five people were in a daze. He asked curiously: "I'm working, why are you dazed?"
"Tutor Xu!"
"I have a little doubt here." Zhou Mendi shouted.
Immediately after,
Zhou Mengdi asked: "Tutor Xu...What is the difference between RDFT's K-S equation and DFT's K-S equation?"
"Uh..."
"The kinetic energy operator of the KS equation of RDFT is a 4X4 matrix. The exchange correlation energy and exchange correlation potential functionals are not the same. The calculation process uses the four-component relativistic density functional calculation method." Xu Mang said seriously: "These are all It’s just a single-electron equation, followed by electronic polymorphism calculations."
Words fall,
Xu Mang looked at Zhou Mengdi with an incredulous expression: "As a top chemistry student, haven't you learned this?"
"..."
"Usually we are on the DFT framework." Zhou Mengdi said helplessly: "Speaking of Mr. Xu, how do you know this density functional theory?"
"nonsense!"
"This is the method of quantum mechanics to study the electronic structure of multi-electron systems. This is my specialty." Xu Mang gave a blank look: "Did you drink too much high-concentration industrial alcohol yesterday? You drank your brain stupidly?"
Zhou Mengdi was so angry, did he have a brain twitch? Asking this kind of mentally retarded question may be... the reason for being too excited.
Subsequently,
Xu Mang successively helped everyone solve their inner doubts, including how to derive heat, electricity, magnetism and optics.
"Attention."
"It must be derived based on quantum mechanics." Xu Mang said solemnly: "And it must be detailed."
"Give you two days, should it be enough?" Xu Mang looked around for a while and said with a smile: "It should be about the same. Five of you, forty-eight hours, will be enough. I will use eight for one person. Complete the main frame in half an hour."
"..."
"..."
"..."
Brother!
We are not a species, OK!
How are you human!
"I went home to rest."
"You guys work hard." Xu Mang thought for a while, silently took out a ten yuan from his pocket, and said: "One person buys a bottle of Wahaha."
Words fall,
Go straight to the laboratory...
"Fuck!"
"Tutor Xu wait a minute, wow haha ​​the price has increased!"
...
With the help of Lao Zhangren's driver, Xu Mang returned to Xiaoman's home, enjoying the supreme experience brought by the 52-inch TV.
However, I never thought,
At this time Mother Yang went home unexpectedly. Seeing Xu Mang lying on the sofa watching TV, the anger on her face can be imagined.
"Xiao Xu!"
"Why did you sleep in the laboratory yesterday?" Mother Yang asked, "This is not possible."
"Auntie, why are you back?" Xu Mang shrugged his head and asked cautiously: "Where is uncle?"
"I'm just going home to get a document." Mother Yang took away a document on the table, and planned to leave the house. She rushed to Xu Mang at the door and said, "I will buy you some food for your waist at night. Live here."
"Oh..."
When Mother Yang left,
Xu Mang returned to his former appearance, lying on the sofa like a dead fish.
Perhaps the conscience was condemned, and Xu Mang opened his own system to see how much the current upgrade card reserve was.
Upgrade card: 95
"Ugh..."
"It's really slow." Xu Mang sighed and silently shut down the system.
At this time,
The phone rang, and Xu Mang glanced at it. He never thought it was his mother.
"Hey?"
"Son."
"mom..."
"When will you go home?" Xu Mu asked.
"Uh...waiting for the holiday." Xu Mang hesitated, and said cautiously: "I...I found a girlfriend."
"Good thing!"
"How old are you this year?" Xu Mu asked.
"It's almost two...twenty, high school classmates, and then admitted to the same university." Xu Mang forced Yang Xiaoman to be born two years early. There is no way... it can't always be said that he is just eighteen years old.
"That's the same zodiac sign as you... er..." Xu Mang thought for a while: "I went to the temple a few days ago and the master said that you hit a woman two or three years younger than you. Quite Vanves, you...then what..."
what?
This...this is Xiaoman!
"Mom, I just lied to you. In fact, she is two or three years younger than me." Xu Mang said with a smile, "She's Yang Xiaoman, very...very beautiful."
"Good, good."
"This year's New Year is going to take home, right?" Xu's mother said happily, "Are there any photos?"
"Have!"
After hanging up,
Xu Mang sent his mother a photo with Xiaoman.
Then it was tragedy.
"Son!" Mother Xu's tone was serious: "It's too late to surrender now, and you will be killed if it is too late."
Xu Mang: 囧
Finished,
Misunderstood again.
"mom!"
"Your daughter-in-law is in college!" Xu Mang said helplessly.
"really?"
"Son...I don't want to do things that break the law. Mom and Dad will have to face people. If you go to jail, how much your dad and I will lose face in front of our relatives." Xu Yu Tong said earnestly, "Qian Don't do bad things."
"Oh..."
The conversation between mother and child ends here, and every time they talk is to let themselves not sin.
The next day,
Xu Mang returned to the laboratory and found that Lin Wan had dark circles under her eyes one by one, as if they had worked all night yesterday.
"Fuck!"
"Are you all done?" Xu Mang was stunned for a moment. For two days originally planned, he never expected that these people would suddenly work madly.
"Tutor Xu."
"Let's see if there is anything wrong." Several people hit Hatch and said with exhaustion: "We are going to die... we are going to die."
"Let's go back."
"I'll do it here."
After Xu Mang drove away Lin Wanwan, he began to check the results of the people's efforts for a night. It took almost three hours, basically without any problems, and then repeated calculations and verifications.
of course,
In order to save time, Xu Mang decided to use super-calculation to help himself complete the calculation and verification.
Soon after borrowing the key to supercomputing, Xu Mang stayed alone in the supercomputing laboratory for one afternoon. He didn't realize it until Yang Xiaoman called him. It was already 4:30 in the afternoon.
...
On the last day to Princeton University,
Xu Mang didn’t go to the laboratory anymore. At present, all that should be done has been done. Now just let Lin Wan proofread by a few people later. As long as the proofreading is successful, you can program immediately and match with the database. After all, the old database is stored A large number of basic material parameters.
According to Xu Mang's estimation, the proofreading time will take about five days, and the proofreading work will be completed on the day of return.
just...
Originally traveling alone, there was a violent airport at this time.
this day,
Yang Xiaoman accompanied Xu Mang to the airport. For the idiot next to him, he didn't use a wheelchair to beat him to death, except for his anger and helplessness. He has such a beautiful girlfriend. What kind of demeanor he wants? What about him.
"Are you nervous?" Yang Xiaoman glanced at Xu Mang who was silent beside him~EbookFREE.me~ and asked curiously, "Are you also nervous?"
"No..."
"Will I be allowed to speak when I think about it." Xu Mang frowned: "I don't have a draft for speaking."
"cut!"
"How could you be allowed to speak on stage?" Yang Xiaoman gave a blank glance: "Your English is only at CET-4, and it takes a lot of effort to communicate with others, and you still speak...make a ghost."
Xu Mang was stunned for a moment, and said with a smile, "I have you. Your English level is so high. If you ask me to speak on stage at that time, you will translate by my side. I will say one sentence and you will translate another sentence."
Yang Xiaoman said dissatisfiedly: "I have a request...you can't mess around."
Hear Xiaoman's words,
Xu Mang's expression gradually became wretched, and he smiled and said, "Okay."
