Chapter 1231: The list that made Xu Mang angry

solution...
solved? !
Director Sun and Professor Guo were a little confused. They looked at Xu Mang with a serious face in surprise. They really understood the meaning of the sentence just now. It was reasonable...just flipped through it a few times and read a few words at most. , As a result, Academician Xu Mang said that he had solved it.
What to solve?
Solve the problems of klystron oscillators?
"Xu..."
"Academician Xu?" Director Sun asked curiously: "You...you just said that you have solved all of them? Have you solved those problems? Is it...is the problem encountered by Professor Guo's team? This... .This...there are many questions, you...are you kidding me?"
Xu Mang shrugged and said calmly: "The core of the problem you are encountering lies in not knowing or understanding the effect of scattering amplitude. I think...Professor Guo shouldn't be in this field, right? You are more of it. You were forcibly pulled in, right?"
Professor Guo was a bit embarrassed. Unlike what Xu Mang said, he was truly an expert in this field, but... he had no idea that the scattering amplitude would be involved...
"I..."
"I am in this field... but I did not expect it to be related to the scattering amplitude." Professor Guo reluctantly said: "Academician Xu...what is going on?"
"Oh..."
"Quite simple." Xu Mang said indifferently: "Scattering amplitude is one of the core physical quantities of quantum field theory, and quantum field theory has flourished with accelerators in particle physics, and the corresponding quantum field theory has also been developed, so scattering Amplitude is a bridge between theory and high-energy experiment."
"I took a look at your files."
"You seem to have thought of the scattering amplitude, but there is no remaining research...A traditional method is used to calculate the scattering amplitude." Xu Mang said calmly: "In principle, it can be applied to the calculation of any circle diagram, but it can With the increase in the number of outer wires or turns, the actual calculation is often very complicated."
Professor Guo nodded and said seriously: "Yes... we thought of using another method to have great simplicity, but... we found that the maximum transcendence part still exceeds simplicity and universality. Adaptability."
Xu Mang smiled: "Let me guess... you have used the amplitude formula of the dendrogram with any number of gluons."
Hearing Xu Mang's words,
Professor Guo was completely stunned. He didn't even say that those methods were used. As a result, Academician Xu got the answer directly. This... Isn't it too exaggerated?
And Director Sun, who was standing on the side, also had an air of horror. Although he was not an expert in this field, he knew something more or less. Hearing Xu Mang was able to analyze what Professor Guo had used only from the words of others. The envisaged method, what strength this is.
"Correct!"
"We did want to use the amplitude formula of the dendrogram with any number of gluons... to understand the amplitude and even the quantum field theory." Professor Guo said seriously: "But...there are many problems we can't solve at all. "
"Of course!"
"Because it has something to do with the mathematical structure of amplitude in field theory." Xu Mang said calmly: "Generally speaking, the result of loop graph amplitude can be expressed by Feynman integral, but the numbers appearing in Feynman integral are not It is not arbitrary, but corresponds to the so-called stage in mathematics."
"and so..."
"Common mathematical functions will not appear in Feynman integrals, such as trigonometric functions, exponential functions, and double log functions." Xu Mang said: "Feynman integrals are more of multiple logarithmic functions and Riemann Zeta numbers. ."
"That's it!"
"I think I know where the problem is." Professor Guo suddenly realized.
Xu Mang raised his head and took a look, and said slowly: "No...you still don't know. What I just said is just the surface, not the core... The reason is simple, because the corresponding amplitudes you think of Relationship, only considering the situation of pure gluon outside."
"Let me ask a question!"
"In the supersymmetric standard model, in addition to gluons and quark particles, the amplitude of the outer line containing quarks is also physically important." Xu Mang calmly said: "So... do they have a similar maximum transcendence relationship? What?"
This...
This is too difficult to answer!
Professor Guo fell into deep thought. He was thinking about how to answer Xu Mang's question.
"Uh..."
"I don't think it's possible." Professor Guo said: "Firstly, the structures of quarks and gluons are very different. Quarks are fermions, and gluons are bosons. Secondly...gluons and quarks have completely different gauge group representations. ."
"Gluons belong to adjoint expressions, while quarks belong to basic expressions, which means that the two are very different in color structure." Professor Guo said, carefully asking: "Academician Xu...what do you think?"
"You only need to make a simple transformation of the color factor, and the quark amplitude and the maximum transcendence of the gluon amplitude are completely equivalent." Xu Mang smiled and said, "Of course... this is just my preliminary calculation. I calculated it in my mind and found it feasible."
"???"
"???"
What do you mean?
I just calculated it in my mind, this...this calculation is a bit big!
Director Sun and Professor Guo were a little at a loss. The two felt a little confused about Xu Mang's words. From a rational point of view, this was impossible to achieve... But if this person was Xu Mang, it might be possible.
And it's just maybe...
"Do you feel very curious?" Xu Mang said with a smile: "Let's do it...I will solve this problem, and then you will solve it by yourself. I will give you at most one month. If it exceeds one month, the relevant progress is still not there. If it reaches more than 30%, I will cancel the cooperative relationship with you, and will be held accountable."
"of course."
"I'm just investigating who it is...to help the flames behind, let you get this project." Xu Mang said calmly.
For a moment,
The atmosphere in the office condensed, and Director Sun felt unprecedented pressure. Sure enough... Academician Xu Mang came here suddenly, definitely to solve this matter... This time is basically over. If the investigation is initiated, it will be Many problems are involved.
At this time,
Xu Mang got up suddenly and walked silently to the door. However, when he reached the door, he suddenly stopped and said to Director Sun behind him: "Dr. Sun... I have something to communicate with you. I hope you can come out. a bit."
"Ok!"
Watching the two leave,
Professor Guo faintly felt a slight strangeness. I heard that Academician Xu Mang proposed a plan to change the environmental framework and passed it unanimously... But today he suddenly came here, is it related to changing the scientific research framework?
may!
This research institute... has a big problem, and this problem... I believe that all institutions across the country have similar conditions.
...
"Academician Xu?"
"you..."
"What do you want?" Director Sun asked.
"Oh..."
"Actually, it's nothing." Xu Mang said with a smile: "I heard that you have a big crack inside. I want to ask...What kind of crack is this crack? Don't use some lies to prevaricate me. Things...it’s not a secret thing in your city."
"..."
"This..."
"In fact, it's because of... the problem of funding." Director Sun said cautiously: "Because our funds...only enough to maintain two or three projects."
"So little funding?"
Xu Mang's face darkened, and he asked, "Since there is so little funding... why do you study all so many people?"
"Because a few years ago our research institute had six or seven projects... It was just that these projects were completed over time, and the follow-ups were not followed up, which led to..." Director Sun sighed and silently He said: "Academician Xu...We also have difficulties."
It sounds pitiful, but Xu Mang has no sympathy with Ben because it is not the case... He just received Xiaoman's WeChat, and the above content made Xu Mang a little helpless.
Actually this question,
It’s almost the same as what I’ve known before... The root reason is that the relevant leaders expand blindly, do not consider the future prospects at all, take advantage of the funding situation, set up various projects randomly, and then recruit various people ...Producing a feeling of being strong on the surface but fragile on the inside.
Any slight change in the environment will result in a huge crack, which cannot be repaired at all.
One more thing,
Any scientific researcher has a strong sense of belonging to the scientific research institution and has a good expectation for the future, and this premise... depends on the research institution respecting talents in all aspects, increasing their sense of gain and paying attention to their ideas.
But it’s a pity,
What I saw from the current situation is another scene, so many research institutes have resigned on a large scale, and this happens to explain the truth, hoping to prove themselves and gain respect.
Yes!
Came with enthusiasm ~EbookFREE.me~ but left in resentment... Some vines entangled between scientific research institutions and talents will definitely be removed, and then take this opportunity to sort out all kinds of things Relationship, achieve win-win and emotional resonance.
Thought of this,
Xu Mang suddenly realized that he had left too much time for those people? Three months... After three months, Xu Yang and Xu Man are both at the age of going to nursery school!
No way!
It’s going to be caught off guard. One month... One month should be almost the end. The next day you have a sense of crisis, you will start to act, and one month later... That basically belongs to the kind of people who work against it. Special...a kind of person who has a hard head and doesn't hit the south wall without looking back.
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, was silent for a long time, and said: "Academician Xu... I can only provide you with a list of which... many people have already penetrated. In this project of the collider, seek your own interests in it."
Xu Mang didn't feel any surprise when he heard these words. On the contrary, he would be very surprised if he said that no one was making small movements inside.
"it is good!"
"You give it to me now!" Xu Mang's expression was still so calm.
however,
Soon... Xu Mang will not calm down.
Xu Mang: (￣︿￣)
I really want to take them to climb the mountain!
Kill them!
