I Don’t Want to Win Lying Down

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.

right!

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 log functions. Xu Mang said: Feynman integrals are more multi-logarithmic functions and Riemann Zeta numbers .”

I see!

I think I know where the problem is. Professor Guo suddenly realized.

Xu Mang looked up, and said slowly, No...you still don't know, what I just said is just on the surface, not the core... The reason is very simple, because the correspondence of these amplitudes you think of relationship, only the case of pure gluon outer lines is considered.

I ask a question!

In the standard model of supersymmetry, in addition to gluons and quark particles, the amplitude of the quark's outer line is equally important in physics. Xu Mang said calmly: Then...is there a similar maximum transcendence relationship for them? Woolen cloth?

this...

This is too difficult to answer!

Professor Guo fell into deep thought, thinking about how to answer Xu Mang's question.

Well...

I don't think it's possible. Professor Guo said: First of all, the structures of quarks and gluons are very different. Quarks are fermions, and gluons are bosons. Secondly...the gauge groups of gluons and quarks are also completely different. .”

Gluons belong to the adjoint representation, while quarks belong to the fundamental representation, which means that the color structure of the two is very different. After Professor Guo finished speaking, he asked cautiously: Academician Xu...what do you think?

It only needs to do a simple transformation of the color factor, and the maximum transcendence part of the quark amplitude and the gluon amplitude is completely equivalent. Xu Mang smiled: Of course... This is just my preliminary calculation, just now I did some calculations in my head and found that it was doable.

???

???

What's the meaning?

I just calculated it in my mind, this... this calculation is a bit heavy!

Director Sun and Professor Guo were a little at a loss. They felt a little puzzled by Xu Mang's words. From a rational point of view, this was impossible...but if this person was Xu Mang, it might be possible.

And it's just maybe...

Are you feeling curious? Xu Mang said with a smile, Well...I'll solve this problem, and then you can solve it yourself. I'll give you a month at most. If it's more than a month, there's still no progress. If it reaches more than 30%, I will cancel the cooperative relationship with you and will pursue relevant responsibilities at the same time.

certainly.

I'm just trying to find out who... was behind the scenes and let you get this project. Xu Mang said calmly.

for a moment,

The atmosphere in the office froze, and Director Sun felt unprecedented pressure. Sure enough...Academician Xu Mang came here suddenly to solve this matter...It's basically over now. A lot of problems are involved.

At this time,

Xu Mang got up suddenly and walked towards the door silently, but when he reached the door, he stopped suddenly and said to Director Sun behind him: Director Sun...I have something that I need to communicate with you, I hope you can come out one time.

OK!

Watching the two leave,

Professor Guo vaguely felt something strange. He had heard that Academician Xu Mang had proposed a plan to change the framework of the environment, and it was unanimously approved... But today he suddenly came here, is it related to the change of the framework of scientific research?

possible!

This institute...has a big problem, and this problem...I believe that there are similar situations in various institutions across the country.

...

Academician Xu?

you...

Do you have anything to do? Director Sun asked.

oh...

Actually, it's nothing. Xu Mang said with a smile: I heard that there is a big rift in you, I want to ask... what kind of rift is this rift, don't use some lies to prevaricate me, this matter Things...in your city, it's not a secret thing.

...

this...

Actually, it's because...of funding. Director Sun said cautiously, Because our funding...is only enough to maintain two to three projects.

Such a small amount of money?

Xu Mang's face darkened, and he asked, Since there is so little funding...why do you study so many people?

Because our research institute had six or seven projects a few years ago... It was only over time that these projects were completed, but the follow-up was not followed up, which led to... Director Sun sighed and silently He said calmly: Academician Xu... We also have difficulties.

It sounded pitiful, but Xu Mang and Ben didn't sympathize with him, because it wasn't the case... He just received Xiaoman's WeChat, and the content on it made Xu Mang a little helpless.

Actually this question,

It's almost the same as the one I knew before... The root cause is that the relevant leaders are blindly expanding, without considering the future prospects at all, taking advantage of the funds, setting up various projects randomly, and then recruiting various people ...produces a feeling of outward strength, but inner vulnerability.

Any slight change in the environment will cause a huge crack, and this crack cannot be repaired at all.

Another point,

Any scientific researcher has a strong sense of belonging to the scientific research institution and has good expectations for the future, and this premise... depends on the research institution respecting talents in all aspects, increasing their sense of gain, and valuing their ideas.

But it's a pity,

From the current situation, we can see another scene, which is why many research institutes have left their jobs on a large scale, and this happens to explain a reason, hoping to prove themselves and gain respect.

yes!

I came here full of enthusiasm, but left in resentment...Some vines entangled between scientific research institutions and talents will definitely be removed, and then take this opportunity to clarify various relationships and achieve a win-win situation. Emotional resonance.

Thinking of this,

Xu Mang suddenly realized, did he leave too much time for those people? Three months... Three months later, both Xu Yang and Xu Man will be old enough to go to nursery school!

no!

If you are caught off guard, one month... one month should be almost the same, and you start to act the next day when you have a sense of crisis, and one month later... then basically belong to the type of people who fight against each other. Special...a kind of person who has a hard head and doesn't look back if he doesn't hit the south wall.

I'm sorry...

Xu's south wall is not made of bricks!

Director Sun...

I want to ask you... Who gave you the klystron oscillator project? Xu Mang's expression suddenly became serious, and he asked seriously.

this...

This... Director Sun glanced at Xu Mang, remained silent for a long time, and said, Academician Xu...I can only provide you with a list, and in this list... many people have already infiltrated In this collider project, seek your own interests in it.

When Xu Mang heard these words, he didn't feel any surprise. On the contrary, if it was said that no one was making small moves inside, he would be very surprised.

good!

Give it to me now! Xu Mang's expression was still so calm.

However,

Soon...Xu Mang became restless.

Xu Mang: (*￣︿￣)

I really want to take them to climb mountains!

kill them!
