The notice finally came down, Xu Mang is in charge of the basic theory part of the theoretical physics major, and he is still satisfied with the reply to this, and according to his own plan, he doesn't need to produce any papers, just give two propositions.

"Huh?"

"How's the high math roll?" Yang Xiaoman just got three MVPs, glanced at Xu Mang, who was in a daze, and asked curiously: "I see that you are happy to press the keyboard, there should be no problem, right?"

"It's okay. ”

"It's a weird title. Xu Mang stretched his waist and said with a smile: "I just received a notice that I am also responsible for the exam papers of basic theory." ”

This...

What's to be done?

Crazy, right?

Yang Xiaoman didn't know what to say for a while, except for constantly praying in his heart for the safety of the candidates, he had no other thoughts.

"Can you let me see the high math papers you came out?" Yang Xiaoman asked, "I'll be your staff officer." ”

"No way!"

"What if it leaks out?" Xu Mang is still principled, and said with a righteous face: "This is stipulated by law, I can't come indiscriminately, in case someone else knows, I won't be able to eat and walk around." ”

Although Yang Xiaoman was a little angry, Xu Mang couldn't find any slots when he did this, after all, he was the one who made the question.

Dinner is naturally takeaway,

But over who to take the takeaway, the two had a lot of disputes.

At last

Yang Xiaoman walked out of the dormitory with an unhappy face, and then returned to Xu Mang with two large bags.

"Badass!"

"I know that I am being pressed with my identity. Yang Xiaoman said angrily.

"How?"

"Do you still have an opinion?" Xu Mang said with a disdainful face: "Even if you have an opinion, you don't have a problem with me, who asked me to publish a paper." ”

Yang Xiaoman wanted to kill him, but finally held back.

The rice was very fragrant, which was like this for Xu Mang, but Xiao Man was very aggrieved, took a bite of white rice, and glared at Xu Mang.

soon

Dinner is over,

It's time for a happy after-dinner walk.

Yang Xiaoman has always regarded this link as the best time to fall in love, and at this time, she held Xu Mang's arm and walked on campus against the cold wind.

"Xiao Man?"

"Huh?"

"What is your unique understanding of history?" Xu Mang asked curiously, "I have to take the final exam of the history department." ”

"What?"

"You don't let go of the history exam?" Yang Xiaoman asked confusedly.

Xu Mang sighed and said helplessly: "Don't mention it... I had to get a good grade in the final exam of the history department, otherwise... Next year, I can only be rated as an associate professor, and after a year and a half of working as an associate professor, I will be rated as a professor again. ”

"Why?"

"I think it's Director Fang who is trying to kill the water chestnut on my body. Xu Mang said: "Originally, I went to the history department to take a class today, but the history department had no classes anymore, so I went in vain." ”

"Oh. ”

"It makes sense for the head of your department to do this, history is relatively boring, if you can calm down, it means that you have grown. Yang Xiaoman said seriously: "But... Do you know what history is?"

Xu Mang: @#¥%... &

it!

What does it mean to understand history?

Joke...

"Alas!"

"Do you know my nickname?" Xu Mang said with a smile: "The moving "Historical Records" is alive, just kidding..."

"Phew!"

"I said how many nicknames do you bastard?" Yang Xiaoman said angrily: "You come up with a nickname for yourself every once in a while, I think you were born to beat me, you have to fight me anything, you want to die?"

Xu Mang: Embarrassed

This Nima...

You're two years younger than me.

The two of them may have been a little tired, so they came to a gazebo and sat for a while.

Then

Yang Xiaoman remembered that when he was in No. 1 Middle School, he saw many girls with adoring faces, and his handsome pretty faces gradually distorted and deformed, and said to Xu Mang silently: "I found that you have been very popular recently, dear Professor Xu... There are a lot of girls who are your fans. ”

Not good!

Something could go wrong.

Xu Mang was keenly aware of the danger, glanced at Xiao Man, and said cautiously: "Doesn't this just reflect your excellence from the side, they can't have me, but I am yours alone." ”

Alas?

It seems to be the case.

Hey

It doesn't matter if you like it, because he belongs to me alone.

Suddenly,

Yang Xiaoman threw himself into Xu Mang's arms with a smile, and said greasy and crookedly: "Hmph... You've passed. ”

But...

The warmth between the two only lasted for an hour, and when Xu Mang tutored Xiao Man in quantum mechanics, he returned to the situation of red faces.

"The essence of quantum mechanics lies in superposition and collapse. Xu Mang said: "In the microscopic world, a quantum state can be in a superposition state, this concept was put forward by Bohr, that is, the great scientist who almost killed Einstein, and many people opposed him at that time, including Schrödinger, one of the founders of quantum mechanics. ”

"Wait!"

"Are you fooling me?" Yang Xiaoman glanced at him: "Shouldn't it be Schrödinger's suggestion? Isn't that Schrödinger's cat an explanation of quantum superposition?"

"No, no, no!"

Schrödinger's cat was just an experiment in the mind, and it was used to refute Bohr's views. Xu Mang said: "Do you want to learn or not? If you don't learn my games, you won't play games!"

Yang Xiaoman pouted and nodded helplessly.

"Do you know about the decay of atoms?" Xu Mang asked: "I take uranium atoms as an example, uranium atoms are unstable atoms, it may turn into lead atoms without warning, and the change of atoms can only change from heavy to light, which means that each weight will decay, we call this process decay." ”

"Atomic decay is a phenomenon that occurs randomly, and it is impossible to predict when an individual atom will decay, which means that there is uncertainty about whether an atom will decay or not. Xu Mang continued: "So Bohr proposed that before observing the decay of atoms, atoms are in a superposition of decay and non-decay. ”

Schrödinger was very upset when he heard this, and Bohr said to Schrödinger that you have the ability to beat me, and then Schrödinger proposed a half-dead cat to refute the idea of quantum superposition. Xu Mang said.

Yang Xiaoman's face is full of black lines, why is this Bohr so similar to Xu Mang?

"Then can you explain Schrödinger's cat, the core of this ideology?" Yang Xiaoman asked.

"Yes!"

"First of all, Bohr's quantum superposition state is acknowledged, but a ridiculous conclusion is derived, thus showing that Bohr's conclusion is absurd. After a pause, Xu Mang said: "It's similar to what you do now, you just listen well and it's over, why are there so many problems?"

Yang Xiaoman gritted his teeth in anger, it was really feng shui in turns, and he said the same thing about him in the past.

In the subsequent about collapse,

Yang Xiaoman quarreled with Xu Mang again, and the quarrel went into the bed.

...

On this day,

Xu Mang took the data disk and found Director Fang.

"Director Fang. ”

"This is my paper. Xu Mang smiled and said, "Absolutely!"

Director Fang glanced at Xu Mang's expression, and with a hint of slut in his smile, he couldn't help but feel a little bad.

"Xu Mang?"

"Huh?"

"What is the difficulty of the higher math part of the paper?"

"It's not difficult. ”

Director Fang didn't believe Xu Mang's words very much, inserted the data disk and looked at the contents inside, and casually clicked on a set of advanced math papers in the freshman year, and almost didn't get angry.

"Is this a high number?" asked Director Fang.

"Yes!"

"I put basic physics in it, and it looks like it's all physics problems, but you need to solve them with advanced numbers. Xu Mang said with a smile: "When doing high math problems, by the way, I have consolidated my knowledge of physics, is it killing two birds with one stone?"

"That is, if the basic physics is not good, I'm sorry... and also to die. Xu Mang said: "When the students see it, their eyes should light up and shout that this volume is exquisite!"

"Xu Mang?" Director Fang smiled bitterly, "Do the students have a grudge against you?"

"No. ”

"I thought about these sets of rolls all night. Xu Mang said: "I don't think it's very difficult. ”

Isn't it hard?

Director Fang is the top in this area, and he casually read a question, and the complexity of it made him feel a little headache.

It's hard to put into words.

He dared to conclude that, throwing away the basic physics, the light is a high-level part,

Even if a student of the mathematics department does it, it is estimated that it will die one by one.

"That's right. ”

"How are you going to score?" Director Fang asked, "How much do you usually share?"

"Zero!"

"I don't know how they're doing. Xu Mang shrugged his shoulders: "You can score as many points as you take the test, and if you are not convinced, come to me, I will kill him!"

Director Fang smiled helplessly, it's harder to find you than me, it's strange that students can find you.

"And... Three days. ”

"You also go back and prepare for the exam. Director Fang said: "This is the last exam in your life, cherish it, you won't have to think about the exam in the future, so do a good job in the exam and draw a perfect end." ”

"Oh..."

Xu Mang was just about to leave, but Director Fang stopped him and said solemnly, "Anyway, you have been living in someone else's dormitory, right?"

"Huh?"

"This... Belch... Not what you think. Xu Mang was a little embarrassed.

"Don't get me wrong. Director Fang said: "Recently, remember to turn off the computer, and when there is still a high math exam, you are responsible for patrolling the invigilator." ”

...

Department of Physics Building,

A sophomore classroom in condensed matter physics.

Although there are no more classes, many students still come to the classroom early to start self-study as usual.

"Huh?"

"Have you heard?" said one student, "Our advanced math paper may have been written by Professor Xu Mangxu, and the entire physics department was written by Professor Xu. ”

"Huh?"

"Are you sure?" another student asked in horror, "Do you have any characteristics of his paper? ”

The student shook his head: "There is too little information about Professor Xu, I heard that he hardly attends classes. ”

"That's not going to work. ”

"We had to do a thorough review, which was a bit stressful. Another student said, "Hopefully... Let's hope it's not too difficult. ”

soon

The paper on the three major advanced mathematics aspects of the entire physics department was written by Xu Mang, and the topic spread instantly.

Of course, it's all speculation at the moment, but rumors will come true after a long time, and some of the arguments in the rumors are well-founded, which has to be convincing.

"Damn, I heard that Professor Xu is not a human being, and his papers are very, very difficult. ”

"No way! It's about to be the New Year, and he can't be so excessive. ”

"That's what I thought too, besides, everyone used to be classmates, right?"

"Hehe, I think... It's hard to say, because it's not usually counted in it..."

it!

Doesn't it count?

How can this keep people alive?

In the midst of speculation and panic,

Students ushered in the final exams of the semester,

It just so happened that the first session of the physics department... It's the legendary high number.

And an hour to go,

The students will be put to the ultimate test by Xu Mang.
