I really don't want to lie down and win

zero...

ten percent...

It's almost the same.

Xu Mang didn't bother to ask whether it was [-]% or zero, so he was just disappointed.

"Ugh..."

"Is there any relevant data?" Xu Mang smiled wryly, "Let me see... see if I can solve it."

"what?"

"Okay, okay!" Professor Guo hurriedly took out a stack of documents, and said cautiously: "Academician Xu...this...this is the difficulty we found."

Xu Mang looked at such a thick stack of documents, and was speechless for a while... But he was soon relieved. Being able to find out so many problems shows that the team is still very attentive. Don't look for problems, just drag on.

after that,

Xu Mang picked up one at random, opened it for a few glances, then closed it silently, then picked up another one, opened it for a few more glances, closed it, and picked up the third one. The piece, or turned over a few times before closing.

Xu Mang's behavior made Director Sun and Professor Guo very confused, and they couldn't figure out what he was doing for a while.

Didn't you say... solve the problem?

Why did you just flip through it a few times and then close it again?How many times can you find the answer to the question?Shouldn't you read it carefully?

What is the situation?

"Xu..."

"Academician Xu?"

"You...what are you doing?" Professor Guo glanced at the half-finished document and asked curiously, "Are you... looking for the answer to the question?"

"more or less."

Xu Mang nodded, and said with a smile, "I'll just take a look first."

just looking around...

that's ok,

After all, this is Academician Xu, so I am not qualified to judge him. He must have his reasons for doing so.

In the next 5 minutes,

There was a weird atmosphere in this office. Xu Mang quickly flipped through the problems found by Professor Guo's team, basically 30 seconds to complete each piece. Director Sun and Professor Guo stood by the side, accompanied the whole process without making any sound. , watching him turn over the papers.

but...

The more I look at it, the more confused I am, what exactly is this doing?

suddenly,

Xu Mang closed the last one, threw it in front of the desk, glanced at the two people beside him, and said calmly, "Okay...it's all settled."

In an instant,

The atmosphere became even more eerie.

......

The first thousand and 230 chapters list that made Xu Mang angry (votes requested)

untie...

solved? !

Director Sun and Professor Guo were a little confused. They looked at Xu Mang with a serious face in surprise. They really figured out what the sentence just said meant. It made sense... I just read a few words, at most read a few words , Academician Xu Mang said that he had already solved it.

solve what?

Solve those intractable diseases of the klystron oscillator?

"Xu..."

"Academician Xu?" Director Sun asked curiously: "You...you just said that you have solved all of them? Solved those problems? Is...is it a problem encountered by Professor Guo's team? This... .This...these are quite a few questions, you...are you kidding me?"

Xu Mang shrugged, and said calmly: "The core of the problems you have encountered is that you don't know or don't understand the effect of scattering amplitude. I think...Professor Guo is not from this field, right? You are more Was it forcibly pulled in?"

Professor Guo was a little embarrassed. Contrary to what Xu Mang said, he was truly an expert in this field, but...he never thought that the scattering amplitude would be involved...

"I..."

"I'm in this field...but I really didn't think it has something to do with the scattering amplitude." Professor Guo said helplessly: "Academician Xu...what's going on here?"

"Oh..."

"Pretty simple." Xu Mang said indifferently: "Scattering amplitude is one of the core physical quantities of quantum field theory, and quantum field theory has flourished in particle physics with accelerators, and the corresponding quantum field theory has also been developed, so scattering Amplitude is the bridge between theory and high-energy experiments."

"I took a look at your files."

"You seem to have thought of the scattering amplitude, but there is no research left...A traditional method is used to calculate the scattering amplitude." Xu Mang said indifferently: "In principle, it can be applied to the calculation of any circle diagram, but any As the number of outside lines or laps increases, the actual calculation is often very complicated.”

Professor Guo nodded, and said seriously: "Yes... We thought about using another method to have great simplicity, but... we found that the part with the greatest transcendence still exceeds the simplicity and common suitability."

Xu Mang smiled: "Let me guess...you used the amplitude formula of the tree diagram containing any number of gluons."

Hearing Xu Mang's words,

Professor Guo was completely stunned. He didn't say that he used those methods at all. As a result, Academician Xu got the answer directly. This...is this too exaggerated?

Director Sun standing by the side also looked terrified. Although he is not an expert in this field, he knows a little bit. Hearing that Xu Mang was able to analyze the words that Professor Guo used just from other people's words. The way to imagine, what strength this is.

"Correct!"

"We once really wanted to use the amplitude formula of the tree diagram containing arbitrary gluons...to understand the amplitude and even the quantum field theory." Professor Guo said seriously: "But...we can't solve many problems in it. "

"Of course!"

"Because it has something to do with the mathematical structure of the amplitude in field theory." Xu Mang said calmly: "Generally speaking, the result of the amplitude of the circle diagram can be expressed by Feynman integral, but the numbers that appear in Feynman integral are not the same. Not arbitrary, but corresponds to what is called phasedness in mathematics."

"so..."

"Common mathematical functions do not appear in Feynman integrals, such as trigonometric functions, exponential functions, and double og functions." Xu Mang said: "The Feynman integrals are more multi-logarithmic functions and Riemann Zeta numbers .”

"I see!"
