Chapter 454: There is an old saying in your country...
"The abnormal data comes from...Academician Zhou and his group."
As Witten said these words.
The entire press conference fell silent for a moment, and the whole audience could hear the needle drop.
On the podium.
Academician Pan's initially polite smile suddenly became stiff.
After a while.
Buzz buzz——
From all directions on the scene, a low whisper sounded without warning, and it looked like two thousand vibrating eggs vibrating.
Some people are surprised.
Some people questioned.
Some people eat melon and watch a show.
Some people were overjoyed.
Christine whistled playfully, Lu Chaoyang clenched his fists hard, and for the first time, a trace of anxiety appeared in Hou Xingyuan's eyes.
at the same time.
In the live broadcast room where [666] barrages had been posted before, question marks floated over again:
【?????】
Some of the more extreme users couldn't help but start making unkind remarks.
If the platform does not have built-in filtering.
At this time, some people even started to spray dirty words.
Mentioned earlier.
Since the dark matter achievement of Pangea particles is used as the basis, the Academy of Science and Technology can basically sit on the Diaoyutai during the calculation process of 'Pluto' particles without worrying about overturning.
But something needs to be noted.
The description used in this sentence is only 'basically', not 'completely' or '100 percent'.
In other words, in terms of probability, there is a certain possibility of an accident happening at the Academy of Sciences.
And this possibility is...
Everyone at the scene deduced the results correctly, and only the Academy of Sciences made a major mistake.
It's just that the probability of this happening is very small, and can even be said to be infinitely close to zero - because the derivation of this magnitude requires a large number of preset parameters in many aspects.
If there is a calculation error in one or even some of the parameters, it is indeed possible.
But the problem is that if there are errors in these parameters, Zhou Shaoping will not be able to generate a self-consistent result.
That is to say, in the entire experimental process, there are only two situations in theory:
Either there is something wrong with the parameters, two people have been tinkering for a long time and can't figure anything out, and the screen with data interruption displays 404 or error.
Or a result can be obtained smoothly, and everyone is happy to see the final verification.
Let’s take another example that’s easier to understand.
It's like you gave ten people the exact same computer parts and then asked them to sit in a row and assemble the computer.
During the assembly process.
Due to unskilled reasons, someone may not secure the memory module properly, or someone may connect the wrong data cable or power supply.
But no matter what kind of mistake it is, the consequence is that the computer cannot boot normally.
But what about the current situation of Zhou Shaoping and others?
It is equivalent to the power being turned on normally and the computer starting up normally, but what pops up is not the Windows system, but the host screen of Super Mario Bros., with a Super Mario jumping in front of you.
This is quite outrageous, and can even be said to challenge cognition.
Think of this.
Zhou Shaoping, who was beside Xu Yun, couldn't help but step forward and asked Witten:
"Mr. Witten, are you sure you read the data correctly?"
Witten shook his head when he heard this, pointed at the data terminal in front of him and said:
"Mr. Zhou, I am willing to use my reputation and personality to guarantee that I did not read any symbols wrongly."
"Mr. Zhou, if you have any objection to my judgment, you can come and check it yourself."
Although Witten's negative tone was quite firm, his expression was not pretty.
After all, this is the home court of the Chinese Academy of Sciences, and as a result, the team representing the Academy of Sciences had another incident...
Although Witten dared to pat his chest and swear that this matter had nothing to do with him, and the Academy of Sciences would not be stupid enough to pin the blame on him, human beings are very social and emotional creatures.
Even though Witten himself has nothing to do with the calculation process, if something happens now, he will be affected to some extent.
The status of China's physics community has been rising year by year in recent years. If you offend the Chinese Academy of Sciences like this, it will obviously be a big loss.
Of course.
Now that things have happened, we can only take one step at a time.
At this time, Zhou Shaoping's face was much uglier than that of Witten, but after all, he was someone who had seen strong winds and waves, so he could still stay awake.
He quickly came to Witten, put his head in front of the data terminal, and looked at the data seriously.
Although Witten's courage to say the above words basically means certain results, for Zhou Shaoping, the person involved, it is obviously impossible to surrender without looking at anything - he is from Gaoyou, not Gaul.
at the same time.
Mr. Yang, Higgs and others also stood beside Zhou Shaoping and looked up the data with him.
As for Xu Yun...
In front of these Nobel Prize-winning or even Nobel Prize-level bosses, naturally he, a little transparent person, could only stand aside and act as a mascot.
However, although he could not see the specific data, Xu Yun had a vague guess in his mind at this time.
At this time, Dirichlet's thinking card had not yet reached the time limit. With the blessing of the elder's vision, Xu Yun's mind began to spin rapidly again.
Could it be that......
Is my previous hunch true?
"..."
A total of eight tabs are displayed on the data terminal, one by one corresponding to the calculation results of the eight groups.
These calculation results are not scattered formulas, but Fermi surface information constructed through parameters.
After all, Fermi noodles are said to be "noodles", but just like there is no wife in the wife cake, there is no husband and wife in the couple's lung slices, and there is no update in the thirty thousand miles a day, Fermi noodles are not a real noodle.
Therefore, what is simulated by the data terminal is naturally not a 3D image, but a statistical column similar to a map, which contains some data that can feed back the Fermi surface.
For example, the Landau level.
This is the decomposition of electron energy into unidirectional kinetic energy plus a simple harmonic energy, and is only related to two quantum numbers kz and v.
In this energy level framework, the free electron energy can be divided into magnetic sub-bands by continuous curves, which is a very important data.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Another example is the cross-section positivity value.
This is also one of the few common concepts between the Fermi surface of particle physics and the Fermi surface of semiconductors, and is related to degeneracy.
However, the Fermi surface of the semiconductor will undergo a macroscopic property change called the De Haas-van Alphen effect, and particle physics is limited to the density range.
Other than that.
There are also particle occupied states, particle distribution functions, peaks of spectral functions, etc...
Still using the previous computer assembly as an example.
The formulas Xu Yun and Zhou Shaoping calculated before are equivalent to the hardware used in the assembly process, that is, data cables, power cables, solid-state drives, etc.
At this time, the Fermi surface data displayed on the terminal is equivalent to the computer configuration analyzed by Master Lu or 360.
For example, the graphics card is 750ti, the hard disk is 120G, etc...
Both provide feedback on computer performance, but compared to the previous assembly process, the content on the data terminal is obviously more intuitive.
"Phase change constant 53.456..."
"The M point is above..."
"Belt covariate 2.±0.004..."
As he read the data line by line, Zhou Shaoping's brows gradually wrinkled.
as expected.
Compared with other eight sets of data (including Witten).
His and Xu Yun's group...let's call them the Academy of Sciences group. There are indeed obvious discrepancies in the data fed back by the Academy of Sciences group.
However, these discrepancies in data seemed a bit strange to Zhou Shaoping.
Because some of the data are normal and consistent with the data of the other eight groups of the same name.
For example, phase change constants, particle distribution functions, etc.
But some of the data are completely different. They are completely two types...it can even be said to be two orders of magnitude.
The concept of magnitude may sound a bit messy, but if you use examples in life to explain it, the perception may be somewhat different:
The mathematical expression of magnitude is a certain power of 10, which is at least ten times.
Generally speaking.
An adult and a mobile phone are exactly one order of magnitude apart if we consider height instead of volume.
In reality, the common height of ordinary adults is only 150-190cm. Occasionally, some tall or short people like Yao Ming or Pandora are as tall as the sky. It is impossible for people to be more than ten centimeters tall.
In other words.
This kind of 'magnitude' error is normally impossible to occur within a certain framework.
At the same time, what makes Zhou Shaoping a little puzzling is...
Except for the obvious difference in magnitude.
These errors...or the derivation of the abnormal data are both Xu Yun and himself, which means that the differences are not caused by mistakes on the part of one party.
But the probability of both of them making mistakes at the same time...
To be honest, it's not a big deal - the reason has been explained above. If there is really a problem with the data, theoretically this 'computer' should not be able to run.
And just when Zhou Shaoping was a little confused.
Anton Segrin beside him suddenly let out a sigh, pointed at a certain line on the screen and said:
"Huh? Look, what's going on?"
"...Zhou, didn't you calculate it from the finite angle rotation?"
Zhou Shaoping had studied abroad in the early years and had a very high level of English. He nodded subconsciously and answered in fluent English:
"That's right, our group did not consider finite-angle rotation. The entry point is the matrix of the rotation operator around the y-axis..."
[A novel app that has been running stably for many years, comparable to the old version of the source-changing app, huanyuanapp, that is used by all chasing bugs.]
As a result, the last yuan character was not finished yet.
Zhou Shaoping suddenly realized something and his expression froze.
After regaining consciousness.
He hurriedly said sorry to Salinger and returned to the screen of the data terminal to read the data.
"Matrix elements....Matrix elements...."
More than ten seconds passed.
A flash of surprise flashed in Zhou Shaoping's eyes.
I see......
He felt a little strange just now.
Why does the abnormal data cover him and Xu Yun, and is mainly distributed in some intervals containing operators?
It turns out that when they selected the coupling base and prepared to make the displacement connection, the direction they chose was not limited-angle displacement rotation.
But...
Matrix element of the rotation operator about the y-axis.
As we all know.
Limited angle rotation.
This is a very common concept in particle physics...or application, involving the relationship between angular momentum and rotation.
For the rotation of a scalar function in a general sense, the angular momentum operator plays the role of a generator, and then just use group theory to consider the rotation function field.
Just like how everyone now uses QQ and WeChat instead of YY or TT, it is a choice after multiple group optimizations.
The difficulty of rotating the matrix element of the operator around the y-axis...or around a certain limited axis is much more complicated.
Because it includes not only tiny angular displacements, but also angular displacements in other scenarios.
While the tiny angular displacement is a loss quantity, the angular displacement space is a connected subgroup of the orthogonal matrix Lie group, that is, the angular displacement does not satisfy the loss quantity addition.
In other words.
Small angular displacement is the Lie algebra of angular displacement, and the scope that needs to be discussed is different.
So although the matrix element of the rotation operator around a certain limited axis will be more accurate under many conditions, most people will still choose the simpler limited-angle rotation - because among all known particles, the latter
All applicable.
That is to say, the so-called accuracy of the former is actually meaningless.
Actually at the beginning.
Zhou Shaoping also considered using limited-angle displacement rotation as the entry point. After all, this is a very routine operation.
But what surprised Zhou Shaoping was that Xu Yun proposed the idea of matrix elements of rotation operators around the y-axis.
Since their conversation was broadcast live, and Xu Yun's idea was in another direction but still feasible, Zhou Shaoping chose to follow the trend.
This chapter is not over yet, please click on the next page to continue reading! The result was unexpected...
Is it this change in the cutting direction that actually led to such a huge error in the entire result?
Think of this.
The next thought that came to Zhou Shaoping's mind was not that he had lost face, but...
How can we keep Xu Yun?
After all, once this incident comes out, Xu Yun will definitely be pushed to the forefront.
By then, the level of oppression by public opinion will even far exceed that of previous smear incidents.
This is not Zhou Shaoping’s imagination, but there is precedent to follow.
The last one who had a brilliant performance like Xu Yun today and then had an accident at home was an athlete called...
LX.
This is a familiar figure who does not need any introduction, and is also an example that cannot be ignored in China's "history of Internet explosions".
The Internet in 2023 will be much more developed than it was in 2008. Any character may be destroyed in an instant, and his or her filter may be shattered.
Zhou Shaoping himself is not actually worried about cyber violence.
Firstly, his information is highly confidential, secondly he does not go online often, and thirdly he comes from that special era, so the pressure from public opinion is nothing to him.
But Xu Yun is different.
Xu Yun is still young now, and his potential is so high that even Zhou Shaoping was amazed.
If your mentality is affected by public opinion...
To know.
Even Marie Curie, who had been blessed with glory at the time, could not withstand the pressure of public opinion after her affair with Langevin was exposed. She ran to a monastery in Gaul and hid for 14 months before she survived the news and stayed.
A mental illness that is difficult to cure throughout life.
And Teacher Zhu Jun.
Because of the deliberate slander by some forces, in just a few years, he seemed to have become a completely different person.
Not long ago, he was exonerated, but no one cared how many bowls he had eaten.
These are examples of big figures in their respective fields, let alone Xu Yun.
But the question is how can I keep Xu Yun?
Take all the responsibility on yourself?
If the public can believe this approach, it will definitely be effective.
But the communication between Xu Yun and himself was public at that time, and he did not show much guidance in the process...
Or should we simply say that this is a preset script?
The feasibility does not seem to be high...
And just when Zhou Shaoping was a little irritable.
Suddenly a sound like a broken blower sounded beside him:
"Zhou Sang, it seems that the Chinese Academy of Sciences has some problems with the selection of candidates this time. It's really a pity..."
Zhou Shaoping took advantage of the situation and looked around.
as expected.
At this time, Atsuto Suzuki was holding his hands behind his back, shaking his head, and looking at the screen of the data terminal with regret.
Seeing Zhou Shaoping looking towards him, Suzuki Atsushi grinned at him again:
"Zhou Sang, you don't have to be too sad. After all, the most important quality for those of us who engage in scientific research is to be able to accept reality."
"For example, you have an old saying in Zhongguo, which is called Xixi Material Wei Junjie. Am I right?"
Suzuki Atsushi's last words were in Chinese, and his smile was so bright that even a vegetable leaf on his back molar could be clearly seen.
After all, this old man had been depressed for the entire press conference, and he thought he would be completely embarrassed today.
The result was unexpected.
Zhou Shaoping and Xu Yun, both old and young, actually gave him such a good opportunity to counterattack at the end of the press conference.
True.
What he said seemed to add insult to injury, and he may receive a lot of criticism after the meeting, even from within Neon.
But he is already about to go to the grave to meet Dabao Bei, and he even acted like a clown at the press conference. Why does he care about this now?
Just ridicule and that's it.
Think of this.
Suzuki Atsushi realized something again and turned his head to look...
Xu Yun on the side.
In a sense, Zhou Shaoping's situation is similar to his own, and he has reached the point where he doesn't need to care too much about public opinion.
But Xu Yun is different.
Judging from the ability he showed today, his potential is comparable to that of Neon Toh University's Masahito Ueda.
No, even several times taller than Masahito Ueda!
Ueda Masahito was far from outstanding at Xu Yun's age.
If this young man could be kicked hard, he would at least be able to stop his losses as much as possible.
So Suzuki Atsushi coughed lightly and asked Xu Yun:
"Xu Sang, have you read the results yourself?"
Xu Yun nodded:
"Watched part of it."
"how do you feel?"
"I removed most of the operators with non-rich terms, but retained some. I think that only by retaining some operators with rich terms can you know that what you are calculating is loss connection."
