Chapter 360: Test of Xu Mang (1/3)

The notice finally came down. Xu Mang was in charge of the basic theory part of the theoretical physics major. He was satisfied with the reply, and according to his own plan, he didn't need to produce any papers, and just gave two propositions.
"Ugh?"
"How's the high number of papers?" Yang Xiaoman just got three MVPs, glanced at Xu Mang in a daze, and asked curiously: "I think you can press the keyboard very happily, there should be no problem, right? ?"
"Okay."
"The question is rather strange." Xu Mang stretched out and said with a grin: "I was notified just now that I was responsible for the examination papers for the basic theory."
This...
What is this going to do?
Are you crazy?
Yang Xiaoman didn't know what to say for a while, and had no other thoughts other than praying for the candidates' safety in his heart.
"Could you show me the high-level papers you produced?" Yang Xiaoman asked, "I'll be your adviser."
"No!"
"What if it leaks out?" Xu Mang still has principles in his life, and said with a face of justice: "This is regulated by law. I can't do it indiscriminately. If others know about it, I won't be able to eat. ."
Although Yang Xiaoman was a little angry, Xu Mang couldn't find any points in doing this. After all, he was the author of the question.
Dinner is naturally a takeaway,
But there was a lot of dispute between the two as to who would take the takeout.
At last,
Yang Xiaoman walked out of the dormitory with an unhappy expression, and then returned to Xu Mang with two big bags.
"Bad!"
"I knew that I was pressed with my identity." Yang Xiaoman said angrily.
"how?"
"Do you have any comments?" Xu Mang said with a disdain: "Even if you have any comments, you still don't have any trouble with me. Who wants me to write the paper."
Yang Xiaoman wanted to kill him, but finally held back.
The meal was very fragrant, like this for Xu Mang, but Xiaoman was very stunned. He took a mouthful of white rice and stared at Xu Mang.
soon,
Dinner is over,
It's a happy walk after dinner.
Yang Xiaoman has always regarded this link as the best time to talk about love. At this time, she took Xu Mang's arm and walked on campus in the cold wind.
"Little Man?"
"Ok?"
"What is your unique understanding of history?" Xu Mang asked curiously: "I want to take the final exam of the History Department."
"what?"
"Did you miss the history exam?" Yang Xiaoman asked in confusion.
Xu Mang sighed and said helplessly: "Don't mention it... I must get a good score in the final exam of the Department of History, otherwise... next year I can only evaluate the associate professor, who will work for a year and a half. Re-evaluated as a professor."
"why?"
"I think it was Director Fang who killed the water chestnut on my body." Xu Mang said, "I went to the history department for a class today, but the history department has no classes anymore, so I went for nothing."
"Oh."
"The dean of your department also makes sense. History is relatively boring. If you can calm down, you have grown up." Yang Xiaoman said seriously: "But...do you know what history is?"
Xu Mang: @#￥%...&
Damn it!
What does it mean to understand history?
joke...
"Ugh!"
"Do you know my nickname?" Xu Mang said with a smile: "The moving "Historical Records" is alive, just kidding..."
"Pooh!"
"How many nicknames do you have?" Yang Xiaoman said angrily, "You come up with a nickname for yourself every three to five times. I think you were born to take advantage of me. You want everything I say. Do you want to die?"
Xu Mang: 囧
This Nima...
Obviously you are two years younger than me.
The two of them may be a little tired, and they came to a pavilion to sit for a while.
At this time,
Yang Xiaoman remembered that when he was in the first middle school, he saw many girls admiring their faces, their handsome faces gradually distorted, and silently said to Xu Mang: "I found you are very red recently, dear Professor Xu... Girls are all your fans."
not good!
Something may happen.
Xu Mang was keenly aware of the danger, glanced at Xiaoman, and cautiously said: "Doesn't this just reflect your excellence from the side, they can't have me, but I am you alone."
Ugh?
This seems to be the case.
Hehe,
It's no use if you like it any more, because he belongs to me alone.
Suddenly,
Yang Xiaoman threw his eyebrows into Xu Mang's arms with a smile, and said greasy and crookedly: "Huh...you pass the level."
but...
The warmth of the two only lasted for an hour, and when Xu Mang taught Xiaoman quantum mechanics, he returned to the red-faced situation.
"The essence of quantum mechanics lies in the superposition state and collapse." Xu Mang said: "In the microscopic world, a quantum state can be in a superposition state. This concept was proposed by Bohr, which almost gave Einstein an air. The dead scientist, many people opposed him at that time, among them was Schrödinger, one of the founders of quantum mechanics."
"and many more!"
"Did you fool me?" Yang Xiaoman gave a white glance: "Shouldn't it be Schrödinger's proposal? Isn't that Schrödinger's cat an explanation of the quantum superposition state?"
"No no no!"
"Schrödinger's cat is just a thought experiment, it is used to refute Bohr's point of view." Xu Mang said: "Are you going to learn? If you don't learn, I will play games!"
Yang Xiaoman pouted and nodded helplessly.
"Do you know atomic decay?" Xu Mang asked: "I take uranium atom as an example. Uranium atom is an unstable atom. It may become lead atom without warning. The change of atom can only change from heavy to light. , Which means that every time the weight will decay, we call this process decay."
"Atomic decay is a phenomenon that occurs randomly. For an individual atom, it is impossible to predict when it will decay, which means that there is uncertainty about whether an atom decays." Xu Mang continued: "So Bohr proposed Before observing the decay of the atom, the atom was in a superposition of decay and non-decay."
"Schrödinger was very upset to hear that, Bohr told Schrödinger that you have the ability to hit me, and then Schrödinger proposed a half-dead cat to refute this quantum superposition concept." Xu Mang said.
Yang Xiaoman's face is full of black lines, why is Bohr so ​​similar to Xu Mang?
"Then you explain Schrodinger's cat, the core of this idea?" Yang Xiaoman asked.
"sure!"
"First of all, I recognized Bohr's quantum superposition state, but deduce a ridiculous conclusion, which shows that Bohr’s conclusion is ridiculous." After a pause, Xu Mang said: "It's similar to what you are doing now. It's over after listening, why are there so many questions?"
Yang Xiaoman gritted his teeth with anger, it was really feng shui turns, he used to say the same.
In the subsequent about collapse,
Yang Xiaoman quarreled with Xu Mang again, and quarrelled under the covers.
...
this day,
Xu Mang took the data disk and found Director Fang.
"Director Fang."
"This is my paper." Xu Mang said with a smile, "Absolutely!"
Director Fang glanced at Xu Mang's expression, and there was a bit of a in his smile, and he couldn't help feeling a little bit bad.
"Xu Mang?"
"what?"
"What is the difficulty of the high-number part of the paper?"
"Not difficult."
Director Fang didn't believe Xu Mang's words very much. He inserted the data disk and checked the contents, and randomly clicked on a set of high-number papers for the freshman year, almost not getting angry.
"This is a high number?" Director Fang asked.
"Yes!"
"I put basic physics in it. It seems that they are all physics problems, but they need to be solved with high numbers." Xu Mang smiled and said, "When doing high numbers problems, by the way, I consolidated my knowledge of physics. Not kill two birds with one stone?"
"That is, if the basic physics is not good, I'm sorry...you will die too." Xu Mang said: "Students should see it, they should be bright, shouting that this volume is exquisite!"
"Xu Mang?" Director Fang smiled bitterly: "Do the students have hatred with you?"
"No."
"I thought about these sets of papers all night." Xu Mang said, "I don't think it is difficult."
Isn't it difficult?
Director Fang is the top in this area, he just read a question casually, and the complexity of it made him feel a little headache.
This is too difficult to describe in words.
He dared to conclude that abandoning basic physics, just the high number part,
Even if students from the Department of Mathematics do it, it is probably a piece of cake.
"correct."
"How do you plan to score?" Director Fang asked: "How much is the average score?"
"zero!"
"I don't know how they usually do." Xu Mang shrugged: "You can get as many points as you take the test. If you don't agree, you will come to me and I will kill him!"
Director Fang smiled helplessly. It is harder to find you than me. It's strange for students to find you.
"three days left."
"You also go back and prepare for the exam." Director Fang said: "This is the last exam in your life, so cherish it. If you think about it in the future, you won't have it, so do a good job in the exam and draw a perfect ending. ."
"Oh..."
Just as Xu Mang was about to leave, Director Fang stopped him and said solemnly, "Say you have been living in someone else's dormitory, right?"
"what?"
"This...er...not what you think." Xu Mang was a little embarrassed.
"Don't get me wrong." Director Fang said: "Recently, remember to shut down the computer, and you will be responsible for patrolling and invigorating the exam during the high-level math exam.
...
Department of Physics Building,
Classroom for the second year of condensed matter physics.
Although there are no classes anymore, many students still come to the classroom early to study on their own as usual.
"Ugh?"
"Have you heard?" A student said, "Our high-number papers may have been written by Professor Xu Mangxu, and the entire Physics Department has been written by Professor Xu."
"what?"
"Sure?" Another student asked in horror: "Are there any characteristics of his paper? If you know the characteristics of the question~EbookFREE.me~, we can review it in a targeted manner."
The student shook his head: "There is too little information about Professor Xu. I heard that he hardly attends classes."
"That's not easy."
"We have to review comprehensively. This is a bit stressful." Another student said: "I hope... I hope it's not too difficult."
soon,
Xu Mang made questions about the three major high-mathematics papers of the entire physics department, and the topic spread instantly.
Of course, it's all speculation at the moment, but the rumors will come true after a long time, and some of the arguments in the rumors are well-founded and have to be convinced.
"Damn, I heard that Professor Xu is not a human being, and his papers are very, very difficult."
"Impossible! New Year's Eve is coming soon, he can't be so excessive."
"I think so too. Besides, everyone used to be classmates somehow?"
"Hehe, I think... it's hard to tell, because usually it doesn't count in it..."
Damn it!
Does not count as usual?
How can this make people live?
In speculation and panic,
The students ushered in the final exam this semester,
It just so happens that the first game of the physics department... is the legendary high number.
There is still an hour,
The students will accept the ultimate test from Xu Mang.
