Chapter 456 There is an old saying among you Guo
"The abnormal data comes from Academician Zhou and his group."
With the export of Wei Teng's words.
The entire press conference site was instantly silent, and needles could be heard.
On the podium.
Academician Pan's originally polite smile became stiff in an instant.
After a while.
buzz buzz—
From all directions on the scene, there was a low-pitched murmur sounded without warning, and it looked like two thousand vibrating eggs vibrating.
Someone was surprised.
Someone questioned.
Some people eat melons to watch the show.
Some people were overjoyed.
Christine whistled playfully, Lu Chaoyang clenched his fists tightly, 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] barrage had been swiped before, a question mark floated again:
【? ? ? ? ? 】
Some extreme users even couldn't help but started to spray unfriendly words.
If it is not the platform's built-in filter.
At this time, some people started to swear if the guarantee was not complete.
Mentioned earlier.
Because of the dark matter achievement of the Pangu particle as a backing, the Academy of Sciences can basically sit on the Diaoyutai in the calculation process of the ‘Pluto’ particle, without worrying about overturning.
But beware.
The description used in this sentence is only 'basically', not 'completely' or '100%'.
That is to say, in terms of probability, there is a certain possibility of accidents in the Academy of Sciences.
And this possibility is.
Everyone on the scene deduced the result correctly, and only the Academy of Sciences made a major mistake.
It’s just that the probability of this happening is very small, and it 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 several parameters, it is indeed possible.
But the problem is that if these parameters are wrong, Zhou Shaoping will not be able to generate a self-consistent result.
That is, the whole experimental process, there are only two situations in theory:
Either there is a problem with the parameters, the two of them have been tinkering for a long time, but they can’t figure out anything, and the screen showing 404 or error is displayed when the data is interrupted.
Either a result was successfully obtained, and everyone watched the final verification with great joy.
Give another example that is easier to understand.
It's like you give ten people the exact same computer accessories and let them sit in a row to build the computer.
During assembly.
Due to unskilled reasons, some people may not fix the memory module properly, or some people 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 be turned on normally.
How about Zhou Shaoping and the others?
It is equivalent to the normal power on, and the computer starts normally, but what comes out is not the Windows system, but the host screen of Xiaobawang, with a Super Mario bouncing in front of you.
This is quite outrageous, and it can even be said to challenge cognition.
Think here.
Zhou Shaoping beside Xu Yun could not help but step forward and asked Wei Teng:
"Mr. Witten, are you sure you read the data correctly?"
Witten shook his head when he heard the words, pointed to the data terminal in front of him and said:
"Mr. Zhou, I would like to guarantee with my reputation and personality that I have not misread any symbols."
"Mr. Zhou, if you disagree with my judgment, you can come and check it yourself."
Witten's tone of denial was quite firm, but his face was not very good-looking.
After all, this is the home field of the Chinese Academy of Sciences, and the team representing the Academy of Sciences has another incident.
Although Wei Teng dared to swear that this matter had nothing to do with him, and the Academy of Sciences could not be stupid enough to put a hat on himself, but human beings are social and emotional creatures.
Even if Witten himself has nothing to do with the calculation process, if something happens right now, he will be somewhat affected.
In recent years, the status of China's physics community has been rising year by year. If it offends the Chinese Academy of Sciences like this, it will obviously be a big loss.
Of course.
Since things have happened, we can only take one step at a time.
At this time, Zhou Shaoping's complexion was much uglier than that of Wei Teng, but he was a person who had seen strong winds and waves after all, so he could still stay awake.
I saw him walking quickly to Wei Teng, put his head in front of the data terminal, and looked at the data seriously.
Although Wei Teng dared to say the above words, it basically represented certain results, but for Zhou Shaoping, the person involved, it was obviously impossible to surrender directly without looking at anything—he was from Gaoyou, not Gaul.
at the same time.
Old Yang, Higgs and others also stood beside Zhou Shaoping, and checked the data with him.
As for Xu Yun.
In front of these Nobel laureates and even Nobel laureates, he, this little transparent, can naturally stand aside and act as a mascot.
Although no specific data can be seen, Xu Yun has a vague guess in his heart at this time.
At this time, Dirichlet's thinking card has not yet expired, and under the blessing of this boss' vision, Xu Yun's mind is spinning again quickly.
Could it be that.
Is my premonition true?
“.”
A total of eight tabs are displayed on the data terminal, corresponding to the calculation results of the eight groups.
These calculation results are not scattered formulas, but the Fermi surface information constructed by parameters.
After all, Fermi noodles are said to be ‘noodles’, but just like there is no wife in wife cakes, there is no husband and wife in husband and wife lung slices, and there is no change in 30,000 miles per day, Fermi noodles are not a real noodle.
Therefore, what the data terminal simulates is naturally not a 3D image, but a statistical column similar to a map, which contains some data that can be fed back to 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 it is only related to two quantum numbers kz and v.
In this energy level framework, free electron energy can be divided into magnetic sub-energy bands by continuous curves, which is a very important data.
Another example is the positive value of the section.
This is also one of the few common concepts of particle physics Fermi surface and semiconductor Fermi surface, which is related to degeneracy.
However, there will be a change in the macroscopic properties of the semiconductor Fermi surface, called the DeHaas-vanAlphen effect, while particle physics is limited to the density range.
Other than that.
There are also particle occupancy states, particle distribution functions, peaks of spectral functions, etc.
Still use the computer assembly as an example.
The formulas calculated by Xu Yun and Zhou Shaoping before are equivalent to the hardware used in the assembly process, that is, data cables, power cables, solid-state drives and so on.
The Fermi surface data displayed on the terminal at this time 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 feedback is computer performance, but compared to the previous assembly process, the content on the data terminal is obviously more intuitive.
"Phase transition constant 53.456"
"M point is above"
"with tie covariate 2.55554±0.004"
As he looked at the data line by line, Zhou Shaoping gradually frowned.
as expected.
Compared with other eight groups of data (including Weiteng).
He and Xu Yun's group is called the Academy of Sciences group. The data fed back by the Academy of Sciences group does have obvious discrepancies.
However, these discrepancies in data, in Zhou Shaoping's view, are a bit weird.
Because some of the data are normal and consistent with the data of the same name in the other eight groups.
Such as phase transition constant, particle distribution function, etc.
However, some of the data are quite different. They are completely of two types. It can even be said that they are of two magnitudes.
The concept of magnitude may sound a bit rotten, but if it is explained with an example in life, the perception may be a little different:
The magnitude is expressed in mathematics as a certain power of 10, that is, at least ten times.
Generally speaking.
An adult and a mobile phone, if the height is considered without considering the volume, they differ by exactly one order of magnitude.
In reality, the common height of ordinary adults is only 150-190. Occasionally, some tall or short people like Yao Ming or Pandora will be invincible, and it is impossible for people with more than ten centimeters to appear.
In other words.
This kind of error in magnitude is normally impossible to appear within a certain framework.
At the same time, what puzzled Zhou Shaoping was that
Except for the obvious difference in magnitude.
The derivation of these errors or abnormal data is both Xu Yun and himself, which means that the difference is not caused by a mistake by one party.
But the probability that two people make mistakes at the same time
To be honest, it’s not that big—the reason has been explained above. If there is a real problem with the data, theoretically this ‘computer’ should not be able to run.
And just when Zhou Shaoping was a little confused.
Anton Segling next to him suddenly gave a light snort, pointed to a certain line on the screen and said:
"Huh? Look, what's going on here?"
".Zhou, didn't you do calculations from vector rotations of limited angles?"
Zhou Shaoping had studied abroad in the early years, and his English proficiency was very high. Hearing this, he subconsciously nodded and replied in fluent English:
"That's right, our group did not consider vector rotation with limited angles, the entry point is the matrix of rotation operators around the y-axis"
As a result, the last metaword has not been finished.
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 look at the data.
"Matrix element matrix element."
More than ten seconds passed.
Zhou Shaoping's eyes flashed a flash of surprise.
I see
He felt a little strange just now.
Why does the abnormal data cover both him and Xu Yun, and it is mainly distributed in some intervals containing operators.
It turned out that when they selected the coupling base and prepared to do vector connection, the direction they chose was not a limited-angle vector rotation.
Instead
Rotate the matrix elements of the operator around the y-axis.
Well known.
Vector rotation of limited angles.
This is a very common concept in particle physics. Or its application involves the relationship between angular momentum and rotation.
For the rotation of the scalar function in a general sense, the angular momentum operator plays the role of the generator, and then only need to use the group theory to consider the rotation function field.
Just like QQ and WeChat are commonly used for voice instead of YY or TT, it is a choice after multiple group optimizations.
And around the y-axis, or around a certain limited axis to rotate the matrix element of the operator, the difficulty is much more complicated.
Because it contains not only small angular displacements, but also angular displacements of other scenarios.
While the small angular displacement is a vector, the angular displacement space is a connected subgroup of the orthogonal matrix Lie group, that is, the angular displacement does not satisfy vector addition.
In other words.
Small angular displacement is the Lie algebra of angular displacement, and the scope of discussion is different.
So although the matrix element of the rotation operator around a certain limited axis will be more accurate in many conditions, most people will still choose the simpler vector rotation of a limited angle-because in all known particles, the latter is all applicable .
That is, the so-called precision of the former is actually meaningless.
Actually at the beginning.
Zhou Shaoping also considers the limited-angle vector rotation as the entry point, after all, this is a very routine operation.
However, to Zhou Shaoping's surprise, Xu Yun proposed the idea of rotating the matrix elements of the operator around the y-axis.
Because their conversation was broadcast live to the outside world, and Xu Yun's idea was in another direction but it was also feasible, so Zhou Shaoping also chose to push the boat along.
The result was unexpected.
Is this change in the cutting direction that actually caused such a huge error in the whole result?
Think here.
The next thought that came to Zhou Shaoping's mind was not that he lost face, but that
How can we keep Xu Yun?
After all, once this incident happens, Xu Yun will definitely be pushed to the forefront.
The degree of oppression of public opinion at that time will even far exceed the previous smear incidents.
This is not Zhou Shaoping's random thinking, but there are precedents to follow.
The last one who had a highlight performance like Xu Yun today, and then had an accident at home was an athlete called
LX.
This is a familiar figure who doesn't need any introduction, and it is also a case that cannot be ignored in China's "Internet Explosion History".
The Internet in 2023 will be much, much more developed than in 2008. Any character may collapse in an instant, and the filter will be broken.
Zhou Shaoping himself is not worried about cyberbullying.
Firstly, his information is highly confidential, secondly, he doesn’t go online often, and thirdly, he is a person from that special era, and the pressure of public opinion is nothing to him.
But Xu Yun is different.
Xu Yun is still young, and Zhou Shaoping is amazed by his high potential.
If the mentality is affected by public opinion.
To know.
Even Madame Curie, who was honored at the beginning, couldn't bear the pressure of public opinion after her love affair with Lang Zhiwan was exposed. She ran to a monastery in Gaul and hid for 14 months. A mental illness that lasts a lifetime.
And teacher Zhu Jun.
Because of the deliberate slander of some forces, in just a few years, he looked as haggard as a different person.
Not long ago he was wronged, but no one cared how many bowls he ate.
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 work.
But at that time, the communication between Xu Yun and himself was public, and he didn’t show much guiding awareness in the process.
Or simply say that this is a preset script?
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 this time the Chinese Academy of Sciences has some problems in the selection of candidates. It is really a pity that it fell to death."
Zhou Shaoping followed the trend and looked.
as expected.
At this moment, Atsuto Suzuki was holding his hands behind his back, shaking his head while looking at the screen of the data terminal with 'regret'.
Seeing Zhou Shaoping looking at him, Atsuto Suzuki grinned at him again:
"Zhou Sang, you don't have to be too sad. After all, the most important quality for us scientific researchers is to be able to accept reality."
"For example, there is an old saying among you Guo, it is called Xixi material Wei Junjie, am I right?"
Atsuto Suzuki's last words were in Chinese, and his smile was so bright that he could clearly see a vegetable leaf on his back molars.
After all, this old Baga was depressed for the entire press conference, and thought that today's old face would be completely lost.
The result was unexpected.
Zhou Shaoping and Xu Yun, the young and old, actually gave him such a good chance to fight back at the end of the press conference.
Indeed.
What he said was a bit of a downer, and he might receive a lot of criticism after the meeting, even from Neon China.
But he is a person who is about to go to the earth to meet Da Baobei, and even acted as a clown at the press conference. How can he care about these things now?
Taunting and that's it.
Think here.
Atsuto Suzuki realized something again, and turned his head to look at.
Xu Yun on the side.
In a sense, Zhou Shaoping's situation is somewhat similar to his own, to the point where he doesn't need to care too much about public opinion.
But Xu Yun is different.
Judging from the ability he has shown today, his potential is comparable to Masahiro Ueda of Neon University.
No, even several times taller than Masahiro Ueda!
Ueda Masahiro was far from being so outstanding at Xu Yun's age.
If this young man can be kicked hard, then he can at least stop the loss as much as possible.
So Atsuto Suzuki coughed lightly and asked Xu Yun:
"Xu Sang, have you read the result yourself?"
Xu Yun nodded:
"Saw part of it."
"how do you feel?"
"I removed most of the operators that are not rich items, but kept some of them. I think you only know that you are counting vector connections by keeping some of the operators that contain rich items."
"Was it intentional or was it accidental?"
"on purpose."
Atsuto Suzuki:
"??????"
