eight and a half hours,

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

And it seems that all the required content of quantum mechanics has been written down. For example, this first-principles calculation involves a total of five principles, and all of them are written down, and the content is shockingly detailed.

For example, this density functional theory is so detailed that even three students from the Department of Physics and the Department of Chemistry had chills running down their spines after seeing it.

That’s not right!

Shouldn't Instructor Xu be happy last night?

Could it be that he is happy and working at the same time?

Crazy?

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

this

This simply subverts the outlook on life.

"Teacher Xu?"

"Have you filled in all the quantum mechanics?" Zhang Xu asked with a shocked look on his face: "In one night?"

"yes."

"What's left is that you can help me with the thermal, electrical, magnetic and optics content, which you can derive from quantum mechanics." Xu Mang said nonchalantly: "After I finish it, I will check it. If it is almost suitable, I will proofread it.

After a while, we finally established a system to connect with the old database."

The words fell,

There was silence in the laboratory, mainly due to the shock of the terrifying speed.

Sure enough, not human

"Right!"

"I checked your research results during the day last night, and then made notes. Please take a look and redo the wrong places." Xu Mang put away his phone, stretched, and silently got up and went to the bathroom.

"???"

"???"

"???"

well?

What's going on?

How can I go to the ground and walk around?

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

"I just got hit in the waist, it's not a powdery fracture." Xu Mang said with a dark face: "I am in a wheelchair because I am afraid of the recurrence of old injuries. Now I need to move around and unblock the 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 people looked at Xu Mang's notes last night. At this time, they didn't want to be too shocked. They always felt that these were normal. After all, Xu Mang and Teacher Xu couldn't think about his various behaviors with normal human thinking.

.

but

His knowledge reserve is really rich. I can't believe that one person's brain 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 move everything in blindly, but selected content closely related to materials science and moved it in.

Almost all of these theories can derive other disciplines, and those disciplines correspond to materials science.

“That’s awesome!”

"I just discovered that relativistic density functional theory can directly derive the properties of heavy element compounds. This is already a chemical discipline." Zhou Mengdi said with admiration: "When he comes back later, I want to ask him carefully.

.”

"well?"

"What's going on?" Xu Mang returned to the laboratory and saw the five people in a daze. He asked curiously: "We are working, why are we dazed?"

"Teacher Xu!"

"I have a little doubt here." Zhou Mengdi shouted.

Immediately afterwards,

Zhou Mengdi asked: "Instructor Xu's equation and equation, what is the difference between the two?"

"Well"

"The kinetic energy operator of the equation is a 4x4 matrix, and the exchange correlation energy and exchange correlation potential functionals are also different. The calculation process requires the four-component relativistic density functional calculation method." Xu Mang said seriously: "These are just single electrons.

Equations, followed by electron polymorphism calculations.”

The words fell,

Xu Mang looked at Zhou Mengdi in disbelief: "As a top student in chemistry, have you never learned this?"

""

"Generally we are based on the DFT framework." Zhou Mengdi said helplessly: "Speaking of Teacher 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 rolled his eyes: "Did you drink too much high-concentration industrial alcohol yesterday? Did you drink your brain stupidly?"

Zhou Mengdi was so angry, did he have a brain twitch? Maybe he was too excited to ask such a mentally retarded question.

Subsequently,

Xu Mang successively helped everyone solve their inner doubts, including how to derive heat, electricity, magnetism and optics.

"Pay attention."

"It must be derived based on quantum mechanics." Xu Mang said seriously: "And it must be detailed."

"It should be enough to give you two days, 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. I can finish it in eight."

The main framework was completed in half an hour.”

""

""

""

Brother!

We are not the same species!

You are not a human being!

"I'm going home to rest."

"You guys work hard." Xu Mang thought for a moment, then silently took out a ten-dollar bill from his pocket and said, "Each person will buy a bottle of Wahaha."

The words fell,

Went directly to the laboratory

"Fuck!"

"Teacher Xu, wait a minute, hahaha, the price has increased!"

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 expected that,

Mother Yang actually came home at this time and saw Xu Mang lying on the sofa watching TV. You can imagine the anger on her face.

"Xiao Xu!"

"Why did you sleep in the laboratory yesterday?" Mother Yang asked, "That's not okay."

"Auntie, why are you back?" Xu Mangla shrugged his head and asked cautiously: "Where is uncle?"

"I just went home to get a document." After Yang's mother took away a document on the table, she planned to leave the house. As soon as she arrived at the door, she said to Xu Mang: "I will buy you some food for your waist tonight. Today I will

Live here."

"oh"

When Mother Yang left,

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

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

Upgrade card: 95
