Xu Mang?

He said that he was Xu Mang?

The professor was stunned for a moment, looked at the other party carefully, what to say... If it weren't for him reminding Liang Feifei, he might have been directly positioned as a not very smart student.

"You..."

"Are you Xu Mang?" the professor asked in surprise, "Xu Mang, the author of the "Electron Proton Synergy Theory"?"

"Hmm!"

"In the next issue of Nature, I will have another paper of mine, "On the Possibility of Superconductivity of Lanthanum Hydride", in which I take high-temperature superconductivity to another level. Xu Mang smiled and said, "That's right... I've also completed a paper on black holes, which I expect to appear in Nature Physics. ”

When the professor heard Xu Mang's words, his originally surprised expression was a little shocked, but at this time he completely believed that this person was Xu Mang, and he was 100% right!

"Xu Mang. ”

"Welcome to Qingdao University. After the professor knew that this person was Xu Mang, he smiled and said, "You should have come to participate in the National College Student Mathematics Competition, right?"

"No, no, no!"

"I was escorted. Xu Mang said helplessly: "Guarantee to the next round." ”

“...”

The professor couldn't laugh or cry, this person was like a demon, proficient in mathematics, physics, materials science, computers... Is this the rhythm that is intended to go to heaven?

"Xu Mang. ”

"I have a request that I want you to grant. The professor said.

"You speak. Xu Mang said.

"I'd like you to come on stage later. "Tell me about your views on theoretical physics, I know you're a freshman, but you've already done a lot of things that professors can't," the professor said. ”

"Okay!" Xu Mang nodded.

meanwhile

Some of those present noticed something unusual in the last row,

“？？？”

“？？？”

“？？？”

What's the situation?

How did the professor talk to this person for so long, and he seemed to be having a good time?

That's right...

Who is he?

The coach returned to the podium, and the students had not yet arrived because the break had not yet ended.

soon

There is still one last minute until class.

The students returned to the classroom one after another, Liang Feifei was one of them, he seemed to be a little relieved at this time, and Xu Mang still smelled a faint smell of smoke.

"Sue * smoke?"

"Huh?"

"Can you smell this?" Liang Feifei looked at Xu Mang with a frightened expression: "Dude... Are you a dog's nose?"

"Sue smoke has a unique taste. Xu Mang said with a smile: "There is a smell of incense, people who are used to it feel very distinctive, but people who are not used to it are very indifferent to it, and I belong to the latter." ”

Liang Feifei smiled bitterly: "Dude... Who the hell are you?"

"Me?"

"A lost little scholar in the world. Xu Mang smiled slightly.

“...”

Liang Feifei felt that he couldn't keep up with Xu Mang's thinking, this speed... It's too fast.

"Ahem!"

"You're lucky today. The professor coughed lightly and said solemnly, "There is a person in our classroom that you did not expect, this person is even more powerful in the field of physics than the professors you know, including me. ”

“...”

“...”

“...”

Yes?

Our classrooms?

This number one?

Everyone looked confused, but a few people looked at Xu Mang, and during the break, they noticed that the professor and the young man were chatting happily.

Combined with the words of the professor at this time, it may be this young man.

"You probably all know him. The professor said: "Not long ago, the cover of Nature had his paper "Electron-Proton Synergy Theory". ”

Hiss!

Could it be...

The students present were amazed.

"He is Xu Mang, who is Fuda. The professor said, "Applause, please Xu Mang, let him come to the podium." ”

Words fall,

Applause,

Then I saw the stranger sitting in the last row, Liang Feifei's side got up and walked over with a smile on his face.

He...

He's Xu Mang?!

Liang Feifei looked at Xu Mang's back in horror, he never thought that he would actually sit with Xu Mang, no wonder he understood everything, and his feelings were genuine cows.

At this point,

Xu Mang stood in front of the podium, glanced at the professor beside him, and asked cautiously, "What am I talking about?"

"Whatever you want. The professor said, "Tell us about your views on the theory of relativity and quantum mechanics, and by the way, your future direction." ”

"Huh?"

"So many?" Xu Mang shrank his head, thought for a moment, and said, "I'll just talk about the conservation of information in black holes that I discovered recently, which happens to involve quantum mechanics and the theory of relativity. ”

"Yes!" the professor nodded in satisfaction.

afterwards

It is Xu Mang's solo performance.

"Hello students!"

"My name is Xu Mang, and I'm from Fuda. Xu Mang smiled slightly: "It's a pleasure to meet you here, actually... I came with my girlfriend, who is a member and captain of the Magic Capital team in the college math competition. ”

"Of course. ”

"My math skills are not bad either, and the reason why I was not there this time was because I was escorted. Xu Mang smiled: "Don't talk about it, let's talk about it, next I will talk about my recent discovery, about Hawking radiation." ”

"This is a kind of black hole thermal radiation speculated by the quantum effect theory, proposed by physicist Professor Stephen Hawking, but there are many problems with this concept, first of all, the problem of conservation of information. ”

"Conservation of information is..."

Xu Mang began to give a lecture, from Hawking radiation to the conservation of information, from the law of entropy to the relationship between matter and information, and tried to use simple and easy-to-understand rhetoric to introduce the concept that conservation of information is the fundamental law of the universe.

And then

At the right time, I would like to mention my paper "Conservation of Information is the Fundamental Law of the Universe: The Mystery of Lost Information".

The students present were stunned for a moment, and many of the contents were completely beyond the scope of their understanding, such as the concept of information entropy.

For the first time, information is described in an abstraction, and has a very complete formula - H(x) = E[I(xi)]= E[log(2,1/P(xi))]=-∑P(xi)log(2,P(xi))(i=1,2,.. n)

Faced with this formula,

Almost all of them chose to quit.

Then there is the theory of cosmic entropy.

The explanation given by Xu Mang is that entropy is actually a spontaneous development direction in nature, with its orderly to disordered development, and the development of low entropy to high entropy value, that is, dS=dS2-dS1 is greater than 0.

Physically, it can be simply understood as a measure of the degree of confusion.

The classmates are confused again... Retire again.

At this point,

A naughty classmate raised his hand and asked Xu Mang, "Xu..."

"Call me by name. ”

"Xu Mang. The student said, "Since we are talking about black holes, can you tell us what kind of changes will be found if people fall into black holes?"

inside a black hole,

It's a very magical and weird existence.

When Xu Mang studied the problem of conservation of information in black holes, he also studied the problems inside black holes by the way.

"This classmate is a little naughty!" Xu Mang smiled: "This is a big problem for me!"

Words fall,

The classmates smiled, it seems that even Xu Mangxu Dashen has problems that he doesn't know.

"Luckily, I studied the internal problems of black holes in passing. Xu Mang said with a smile: "I'll just say it roughly, if you understand it or not, it doesn't matter what I do." ”

“？？？”

“？？？”

“？？？”

Really all-powerful?

This... It's not a joke, is it?

however

Xu Mang didn't joke, but came straight to the truth.

"A black hole has three physical parameters, its mass, angular momentum, and charge. Xu Mang said: "Mass determines the size of the black hole, angular momentum is the physical quantity of any rotating object, if it does not rotate, it is equal to zero, and the charge should be understood, right?"

"There are four classifications of black holes based on rotation and charge. Xu Mang said: "Each type of black hole is different inside. ”

"For the sake of time, I'm going to talk about Schwarzschild black holes, i.e., black holes that are not charged and do not rotate. Xu Mang said: "This kind of black hole has only one parameter... Mass, let's throw the student who asked the question to the edge of the black hole and let him approach the black hole. ”

"Then we can see that the closer it gets to the black hole, the slower it becomes, and according to general relativity, this is because space-time is distorted and the passage of time slows down. Xu Mang continued: "And this classmate will become more and more red, and the time for the frequency of light to be distorted will decrease lower and lower. ”

"And then... This student will reach the infinite redshift plane, where the frequency of light will reach a point where it can no longer be reduced, and then he will be stretched by the tidal force, and if it exceeds a certain threshold, it will be torn apart. Xu Mang paused: "If you're lucky... This classmate was not torn apart, but flew over the red shift surface, and there would be two scenarios. ”

"From a quantum mechanics point of view, he would encounter a wall of fire and be burned to the point that there was no scum left, but from the general theory of relativity, this classmate would go to the singularity of a black hole and be torn apart. Xu Mang said.

Words fall,

Xu Mang glanced at his classmates and felt that at this moment, they were completely listening to books like they were in English class in high school.

Xu Mang sighed: "Don't ask random questions next time, I don't have any pressure at all, but you are easy to be autistic." ”

“...”

“...”

“...”

truly

The classmates have been autistic.

Originally, I wanted to ask about the others, but now it seems that even if I asked, I would ask in vain, because I didn't understand.

"Ahem!"

"It was wonderful. The professor reluctantly walked to the side and said to the students: "Actually, theoretical physics is quite simple, look how well Xu Mang learns." ”

Professor!

It's too much!

Let's take Xu Mang as an example...

The students looked helpless, if they had the strength of Xu Mang, they would still be sitting here?

soon

Classes are over.

The students rushed to take a photo with Xu Mang, and finally at Xu Mang's suggestion, a group photo came.

Everyone cherishes this photo very much, maybe one day Xu Mang will win the Nobel Prize in Physics, and then he can go out to brag and brag, he has listened to the class of Xu Mang, the Nobel Prize winner in physics, and has taken a photo with him.

It is also a capital that can be boasted of.

In the classroom at this time,

There are only two left, Xu Mang and the professor,

"Xu Mang!"

"Can you tell me what you plan to study in the future?" the professor asked curiously, "I see that you are involved in many fields, from astrophysics to condensed matter physics, from materials science to computers, which... The span is a bit large. ”

Xu Mang smiled: "My dream is to find the only truth in the universe and accomplish a feat that even Einstein did not complete." ”

...

Following

Seven thirty.

The person who firmly believes that the ugly person is still sleeping, and the handsome person has already gotten up to wash up briefly, and then took the scratch paper and USB flash drive, Xu Mang went to the mathematics department building of Qingdao University.

Yesterday he found out about the class time of the doctoral class, half past eight in the morning, which is still the old place.

As soon as I walked into the classroom, I met an acquaintance.

"Huh?"

"You're on the wrong shift again today?"

......
