Eight and a half hours,

How can you write so much content in an all-nighter?

And... It seems that all the required quantum mechanics content has been written, for example, this first-principles calculation, which involves a total of five principles, has been written all of them, and the content is outrageously detailed.

For example, this density functional theory is so detailed that even three students from the physics department and the chemistry department felt a chill down their spines when they saw it.

That's not right!

Shouldn't Tutor Xu be happy last night?

Is he working while having fun?

Crazy, right?

The five of them glanced at Xu Mang, who was lying on the tightrope bed, and saw him playing with his mobile phone with a comfortable face, laughing from time to time, the ghost knows what he was looking at, but now he is very happy.

This...

It's a game-changer for life.

"Mentor Xu?"

"You have filled in all the quantum mechanics?" Zhang Xu asked with a shocked face, "One night's time?"

"That's right. ”

"The rest of you help me figure it out, the content of heat, electricity, magnetism, and optics, which you derive from quantum mechanics. Xu Mang said nonchalantly: "After I finish it, I will check it, if it is almost appropriate, proofread it again, and finally establish a system to connect with the old database." ”

Words fall,

The laboratory was silent, mainly shocked by the terrifying speed.

Sure enough, it's not human...

"That's right!"

"I checked your day's research last night, and then made a note, you can take a look and do a new job of the wrong place. Xu Mang put away his mobile phone, stretched his waist, and got up silently to go to the bathroom.

“？？？”

“？？？”

“？？？”

Alas?

What's the situation?

How can you get off the ground and walk around?

"Xu... Mentor Xu?" Lin Wanwan asked in horror, "You... You don't need a wheelchair anymore?"

"I just got a flash in the waist, and it wasn't a powder fracture. Xu Mang said with a dark face: "I am afraid of the recurrence of old injuries in a wheelchair, and now I want to move and unblock blood vessels, do you understand medicine?"

“...”

Lin Wanwan didn't want to speak, she just wanted to smash a brick on Xu Mang's head.

When Xu Mang left,

The five of them looked at Xu Mang's remarks last night, and the few people at this time didn't want to be too shocked by anything, they always felt that these were normal, after all, Mentor Xu Mang couldn't think about his various behaviors with normal human thinking.

But...

His knowledge reserve is really rich, and he can't imagine that a person's brain can hold so many things.

After processing yesterday's research results, several people returned to the framework of quantum mechanics, Xu Mang did not blindly move everything in, and chose the content closely related to materials science to move in.

And almost all of these theories can be derived from other disciplines, which correspond to materials science.

"That's amazing!"

"I just discovered the relativistic density functional theory... The properties of heavy element compounds can be derived directly from it, which is already a discipline of chemistry. Zhou Mengdi said with a look of adoration: "Wait a moment when he comes back, I want to ask carefully." ”

"Huh?"

"What's the situation?" Xu Mang returned to the laboratory and saw that the five people were in a daze, and asked curiously, "What are you doing at work?"

"Mentor Xu!"

"I'm a little confused here. Zhou Mengdi shouted.

Followed by

Zhou Mengdi asked, "Mentor Xu... What is the difference between the K-S equation of RDFT and the K-S equation of DFT?"

"Uh..."

"The K-S equation of RDFT is a 4X4 matrix in kinetic energy operator, and the commutative correlation energy and commutative correlation potential functional are also different, and the calculation process uses the four-component relativistic density functional calculation method. Xu Mang said seriously: "These are just single-electron equations, and there are electron polymorphic calculations behind them. ”

Words fall,

Xu Mang looked at Zhou Mengdi in disbelief: "As a top student of chemistry, you haven't studied this?"

“...”

"Usually we are on the framework of DFT. Zhou Mengdi said helplessly: "Speaking of Mentor Xu, how do you know this density functional theory?"

"Nonsense!"

"This is the quantum mechanics method of studying the electronic structure of multi-electron systems, and this is my specialty. Xu Mang glanced at him: "Did you drink too much high-concentration industrial alcohol yesterday?

Zhou Mengdi is so angry, is his brain pumping? Asking this kind of mentally retarded question, maybe... It's 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 has to be derived based on quantum mechanics. Xu Mang said solemnly: "And it must be detailed." ”

"Giving you two days, it should be enough, right?" Xu Mang looked around and said with a smile: "It should be about the same, five of you can complete it in forty-eight hours, and I will complete the main framework in eight and a half hours alone." ”

“...”

“...”

“...”

Eldest brother!

We are not a species of good!

You are human!

"I went home and rested. ”

"You guys work hard. Xu Mang thought for a while, silently took out a ten-yuan piece from his pocket, and said, "One person buys a bottle of Wahaha." ”

Words fall,

Went straight to the lab...

"it!"

"Mentor Xu, wait a minute, the price has risen!"

...

With the help of his father-in-law's driver, Xu Mang returned to Xiaoman's home and enjoyed the supreme experience brought by the 52-inch TV.

However, I never thought that

At this time, Yang's mother actually went home and saw Xu Mang lying on the sofa watching TV, the anger on her face can be imagined.

"Xiao Xu!"

"Why did you sleep in the lab yesterday?" Yang Mu asked, "That's not going to work." ”

"Auntie, why are you back?" Xu Mangla shrugged his head and asked cautiously, "Uncle?"

"I just went home and got a document. After Mother Yang took a document on the table, she was about to leave the house, and just arrived at the door and said to Xu Mang: "I will buy you some ingredients to replenish your waist in the evening, and live here today." ”

"Oh..."

When Yang's mother left,

Xu Mang returned to his old appearance, lying on the sofa like a dead fish.

Perhaps his conscience was condemned, Xu Mang opened his system to see how much the current upgrade card reserve was.

Upgrade card: 95

"Ugh..."

"It's really slow. Xu Mang sighed and silently turned off the system.

Then

The phone rang, Xu Mang glanced at it, and never expected it to be his mother's.

"Hello?"

"Son. ”

"Mom..."

"When are you going home?" asked Xu's mother.

"Uh... Wait for the holidays. Xu Mang hesitated for a moment, and said cautiously: "I... I got a girlfriend. ”

"What a good thing!"

"How old are you this year?" asked Mother Xu.

"Hurry two... Twenty years old, classmates in high school, and then admitted to the same university. "Xu Mang forcibly let Yang Xiaoman be born two years early, there is no way... It can't always be said that you are just eighteen years old last year.

"That's the same zodiac sign as you... Uh..."Xu Mang pondered for a moment: "I went to the temple a few days ago to calculate, the master said that you have a woman in your life, two or three years younger than you, this person is quite a prosperous man, you... So what..."

Yes?

This... Isn't this Xiao Man!

"Mom, I just lied to you, in fact, she is two or three years younger than me. Xu Mang said with a smile: "Her name is Yang Xiaoman, it's quite... It's pretty. ”

"Good, good. ”

"Are you going to take home this year's New Year?" Xu's mother said happily: "Do you have a photo?"

"Yes!"

After hanging up,

Xu Mang sent a photo with Xiaoman to his mother,

Then tragedy came.

"Son!" Xu's mother said in a serious tone: "It's still too late to turn yourself in, and if it's too late, you will be killed." ”

Xu Mang: Embarrassed

Finished

Misunderstood again.

"Mom!"

"Your daughter-in-law is in college!" Xu Mang said helplessly.

"Really?"

"Son... Illegal things, we must not do it, parents want to be face-saving people, if you go to prison, how much face will your father and I lose in front of our relatives. Mother Xu said earnestly: "Don't do bad things." ”

"Oh..."

This is the end of the conversation between mother and son, and every call is to keep yourself from sinning.

Following

Xu Mang returned to the laboratory and found that Lin Wanwan and the others had dark circles under their eyes one by one, as if they had worked all night yesterday.

"it!"

"Are you all done?" Xu Mang was stunned for a moment, he had planned two days, but he never thought that these people would suddenly work like crazy.

"Mentor Xu. ”

"You see if there's anything wrong. A few of them hit a hache and said with a tired face: "We're going to do it... I'm going to die. ”

"Let's go back. ”

"I'll just be here. ”

After Xu Mang drove Lin Wanwan and the others away, he began to check the results of several people's efforts overnight, which took almost three hours, and there were basically no problems, followed by repeated calculations and verification.

Of course

In order to save time, Xu Mang decided to use supercomputing to help him complete the calculation and verification.

Soon borrowed the key to the supercomputer, Xu Mang stayed alone in the supercomputer laboratory for an afternoon, and it was not until Yang Xiaoman called him that he reacted, it was already half past four in the afternoon.

...

On the last day of travel to Princeton University,

Xu Mang didn't go to the laboratory again, everything that should be done has been done at present, now he only needs to let Lin Wanwan proofread a few people, as long as the proofreading is successful, he can be programmed immediately, and then match with the database, after all, the old database stores a large number of basic parameters of materials.

According to Xu Mang's estimate, the proofreading time will take about five days, and the proofreading work will be completed on the day he returns.

It's just that...

Originally, a one-person trip was now a violent airport.

On this day,

Yang Xiaoman accompanied Xu Mang to the airport, for the idiot next to him, who killed the behavior of not sitting in a wheelchair, in addition to anger, he was helpless, he had such a beautiful girlfriend, what kind of demeanor do he want, and he would not dislike him.

"Are you nervous?" Yang Xiaoman glanced at Xu Mang, who was silent beside him, and asked with curiosity on his face, "Are you nervous too?"

"It's not..."

"I wondered if I would be allowed to speak then. Xu Mang frowned: "I don't have a draft for a speech." ”

"Cut!"

"How could you possibly be allowed to speak on stage. Yang Xiaoman glanced at him: "Your English is only level 4, and it is difficult to communicate with others, and you can speak... it. ”

Xu Mang was stunned for a moment, and said with a smile: "I don't have you, your English level is so high, if I am asked to speak on stage when the time comes, you will translate by my side, I will say a word, you will translate a sentence." ”

Yang Xiaoman said dissatisfiedly: "I have a request... You can't mess around. ”

Hearing Xiao Man's words,

Xu Mang's expression gradually became obscene, and he said with a smile: "Okay." ”
