It's hard to describe Sun Yu's mood at this time, the first time he saw a few pages full of papyrus, he thought it was this student scribbling when he was bored, but when he read it carefully, he found that it was rigorous mathematical reasoning.

The problem is, he only read the first few lines of the first page!

What is the origin of this kid, his face is a little unfamiliar!

Sun Yu is a teaching assistant who has only taken over this semester, and Zhou Xing has hardly been to the previous class, so of course he doesn't know him.

The original words of reprimand were swallowed back, and Sun Yu began to think about Zhou Xing's idea of solving the problem little by little, but the rustle of the other party's pen made him unable to calm down, and he wrote too fast.

After a while, someone finished answering the previous question, and someone began to whisper in the classroom,

"What does this last question mean?"

"I don't know, is this an essay question?" It's no wonder that, according to the title requirements, it is more like an expository essay in a popular science magazine.

"yes, is that a question? I don't think I've only seen it in it. ”

"Wouldn't it be amazing if the space overlapped!"

At first, the sound was muffled, but it grew louder and louder, and gradually became a buzzing sound.

Li Ke was also busy answering, and he gave up the last question directly, and he couldn't even understand the question, how to solve it?

The professor must have been joking, and if he had written, Li Ke would have been able to say two sentences.

He squinted at Zhou Xing, intending to see his answers, compare them, and see if there were any omissions in the copy, and when he turned his head and was startled, he didn't know when, the teaching assistant was standing behind the two.

"Two more pieces of paper!" Zhou Xing stretched out his hand again, "Are you done answering?" Then give me this book, it may take many pages, the conditions of this topic are very complicated. ”

"En?" Li Keda glanced at the assistant teacher, and found that the other party was chattering, staring at Zhou Xing's straw paper in a daze, and he didn't know what he was thinking.

Zhou Xing was also not polite, and without waiting for Li Ke to agree, he reached out and pulled the notebook over.

There was already a lot of straw paper in front of him, which was densely written with formulas, and Li Keda could only barely recognize that there were full differential formulas, and some integral formulas, and between the formulas, there were also a lot of images, circles and circles that looked like field distributions, and things like curves.

Gotcha, Zhou Xueba wants to go against the sky!

Zhou Xing's pen gradually slowed down, trying while thinking, he didn't understand deeply at the time, and only barely memorized part of it.

"Can this problem be solved?"

Finally someone found the problem and exclaimed in a low voice, and soon, more people came around, seeing that the assistant teacher did not stop it, everyone was even more courageous, and everyone stared at Zhou Xing like an alien for the sake of being three layers inside and three layers outside.

The last question, someone is actually solving it!

Isn't the world too crazy, or are we all asleep in class?

This question looks like I should write a popular science article, what the hell is it to express it mathematically!

Rightly or wrongly, this guy is a man of God!

"Look, he's not ......"

"Zhou Xing, the boss of Huanyu!"

"Quiet!"

The teaching assistant also noticed the problem and shouted, and the noise in the classroom went down, but no one left.

The teaching assistant didn't force it, and arranged for the class representatives to collect the papers, looking at the current situation, they didn't have the heart to answer anymore, he didn't move, he pulled a piece of straw paper from the side, and followed the calculation.

What does this string of mathematical symbols mean? As soon as I put pen to paper, the teaching assistant felt like he had been fed to a dog after so many years of learning.

His mind was full of question marks, and he wanted to ask Zhou Xing, which showed that he was focused, and he was too embarrassed to bother.

Cai Zijian returned to the office, sat down and took a sip of water, and flipped through the lesson plan in his hand, only to find that the paper on which he recorded his inspiration today had been torn off.

Oh no, it must have been when I left the topic, and the assistant ripped it off together.

He hurriedly rushed out of the door and rushed to the classroom, but don't throw it away for me as waste paper!

Before I got to the classroom, the noise came out, and I could hear it clearly from a distance.

Cai Zijian secretly got angry, how did the teaching assistant do it, is this an exam or a tea party, if he is heard by others, he will think that he Cai Zijian is not strict in his studies.

With a gloomy face, he entered the classroom.

There is no exam in the classroom at all, there are three floors inside and three floors outside, and people outside are jumping their feet to look inside, as if there is some amazing scenery inside.

"Classmate, what are you looking at?"

"Hehe, I don't know, there are people in there doing the fifth question, and the real god is also!" the student turned his head after speaking, and when he saw that it was Cai Zijian, he instinctively let out a shout.

"Ah, Mr. Cai!"

Coax, the onlookers quickly got out of the way and made a way.

When Cai Zijian walked inside, he saw Sun Yu holding two pages, and he was fascinated.

Cai Zijian saw Zhou Xing in the middle at a glance, and secretly rejoiced in his heart, this kid was finally caught by me, and this time I can't let him run easily.

Seeing that Zhou Xing was still writing hard, Cai Zijian didn't step forward to disturb, but walked around behind Sun Yu and stood on tiptoe.

"Differentiation on both sides, yes, it should be, but how did this condition come about after differentiation, oh my God, I'm going to explode!" Sun Yu was hysterical, muttering frantically, which startled Cai Zijian, what is it, as for it!

He swept it on the paper and instantly recognized that this was exactly the problem he had considered before, and the lines of formulas on the paper were obviously a rigorous derivation process.

"This boundary condition is derived from this piece, but the relationship between the two should be proven, so there are still some problems with such direct use!"

Cai Zijian looked at it for a while, and finally couldn't help but speak.

"Professor Cai!" Sun Yu realized that Cai Zijian was standing behind him, and it seemed that he had been here for a while.

"Shhhhh

It is unimaginable that in such a short period of time, someone can reason this topic to such a point, and even he himself only has a fleeting aura.

He began to examine Zhou Xing's papyrus page by page, sometimes frowning and pondering, sometimes clapping his legs and shouting, but he suppressed his excitement, for fear of disturbing Zhou Xing, who was constantly deriving.

Cai Zijian has always felt that Zhou Xing's kid has some achievements, so he is a little arrogant, and he has been taking physics classes in college for more than half a year, and this kid has only taken a handful of classes......

However, everyone has reached this level!

It's ironic to be a professor myself!

He quietly took a few steps back, took out his mobile phone, took a few photos of the straw paper, and sent them to the group of physics teachers, and soon, the information in the group exploded.

"I'll you, team leader, did you deduce it?"

"The team leader is amazing, the admiration for you is like a surging river, you can break through such an abstract thing. ”

"It's amazing my group, Teng Yunxuan in the evening, the team leader is in for a treat!"

After a group of young people finished ridiculing, a few people like Cai Zijian, who studied theoretical physics, immediately appeared.

"Where, say it!"

"Oh my God, Lao Cai actually touched the edge!"

"Tell me, I'm in a hurry!"

The eager tone made Cai Zijian amused for a while, and he knew that it would be like this.

These people can be called old pedants who can die at the end of the day, and they will see the information sent by Cai Zijian, how can they bear it.

Although it is impossible for them to deduce it in detail in such a short period of time, with their abilities, sometimes all they need is a fleeting aura.

With Cai Zijian's derivation, many stuck research topics can be further developed, after all, the problem involves too many levels.

Don't underestimate this step, for some fields, affecting human beings is a big step.
