MTL - Into Unscientific-Chapter 432 Sure enough, someone made trouble
Chapter 432 Sure enough, someone is causing trouble
Conference room scene.
In the expectation of everyone in the audience.
Academician Pan walked slowly but firmly to the podium.
He first laid the speech paper flat on the table, took a deep breath, and then looked around.
Judging from the resume.
Academician Pan is undoubtedly a standard 'become famous at a young age'.
He was selected as a young scholar 22 years ago, and has won the Schmid Award and the Marie Curie Outstanding Research Award in 2004.
In 2005, he was selected as one of the top ten outstanding youths in China.
Won the Fresnel Award in 2006.
In 2016.
He won the highest honor in the Chinese scientific community, the first prize of the National Natural Science Award.
In these large and small award ceremonies, Academician Pan often gave various reports to the bosses.
But whether it is the graduation report as a student representative at the doctoral graduation ceremony, or the acceptance speech at the National Natural Science First Prize Award Ceremony.
Never made Academician Pan so excited, or nervous.
In a sense.
This press conference is not only about the academic status of Academician Pan, but more importantly, it determines whether Huaxia can have a place in the high-energy physics community in the future.
In other words.
This is also a press conference involving the National Games.
Since it involves national destiny, there will be a fight between dragons and tigers.
Whether in front of the stage or.
Behind the scenes.
Then Academician Pan settled down and said:
"Everyone on site, industry guests and reporters, colleagues and audience outside the broadcast camera, hello everyone, I am Pan Jianwei from Huaxia University of Science and Technology."
"It is a great honor to represent the Chinese Academy of Sciences and share an exciting report with you here."
"The content of this report must have been heard by everyone—yes, with the joint efforts of many experts in the Chinese physics field, we discovered and verified the real cold dark matter!"
The moment Academician Pan spoke.
The audience outside the screen may not feel it, but many Chinese experts at the meeting were taken aback.
because
The language used by Academician Pan is not English, but standard .
Huaxia!
To know.
Generally.
For this type of international press conference, all speakers should use English—this is already a default rule.
So if you pay attention to those scientific conferences, you can often see Chinese, Japanese and curry-style English speeches.
But today is different.
Academician Pan’s use of Chinese is the result of repeated discussions, including the leaders of the Academy of Sciences and a group of academicians.
After all, this is the brightest moment in the Chinese physics field so far, and the location of the conference is still our home stadium, in such an ancient building.
That being the case.
Then just use Huaxia.
Politely speaking, it is to respect the language of the host country and let the world understand Chinese culture.
Human words just like listening to them or not.
Anyway, there are simultaneous translators these days, which can basically keep up with the introduction of Academician Pan.
By the way.
The provider of translation equipment is iFLYTEK, one of the well-known subsidiaries of HKUST.
Of course.
It is also because of the Chinese language that many viewers have noticed the last few words of Academician Pan:
Cold dark matter.
During the past few days.
The concepts of hot, warm, and cold dark matter are the mainstream of science popularization on the Internet.
Some of these science popularizations are true and objective analysis, while others are based on personal emotions or suspicions of distrust.
The rational party, represented by the blogger named [Zhajiangmian yyds], swears every day that the Academy of Sciences has at most discovered warm and dark matter this time, playing word games from beginning to end.
And the first sentence that Academician Pan said right now, directly dispelled this possibility verbally.
In other words.
In this press conference, there is no so-called retreat.
After speaking the pre-arranged beginning of this part.
Academician Pan lightly pressed the laser pointer in his hand, and the big screen behind him quickly changed into a vast starry sky:
"As we all know, the discovery of dark matter can be traced back to the 1970s, and it is an important part of cosmic physics."
"It, together with gravitational waves and the Higgs particle, is called the three phantom gods that must be resolved in the 21st century."
"Now that the Higgs particle has been discovered by CERN, and gravitational waves have been successfully detected by LIGO, dark matter has become that lonely little unlucky egg."
"Currently all observational evidence proves that 99% of dark matter exists, but before that, we still can only discover various hot dark matter, or... warm dark matter."
After Academician Pan finished speaking, he paused for a while.
At the same time, the camera that originally focused on Academician Pan also instantly switched to Atsuto Suzuki sitting in the fourth row.
Atsuto Suzuki still had a dull expression on his face, but after the camera turned away, he couldn't help but snorted coldly.
idiot
These Chinese people must have done it on purpose!
Then Academician Pan smiled very elegantly, and said:
"But what's interesting is that just over four months ago, a series of very subtle things happened."
I saw him press the laser pointer again, and the introduction of Zhao Zhengguo appeared on the screen:
"On a drizzling day, my colleague Zhao Zhengguo, a professor of physics at the University of Science and Technology of China and a member of the Huaxia Academy of Sciences, discovered a brand new ∧ hyperon in a decay sample."
"This hyperon was soon published on pdgLive, and the particle number is 4685. Presumably some colleagues at the scene should have some impressions."
Hear this statement.
A small number of scholars in the audience nodded.
Most of these scholars are engaged in the research of baryons, so they all have a certain memory of the 4685 hyperon.
After all, hypersons or baryons have always been a very hot research topic.
However, there are not many scholars in this group, and more experts took out their mobile phones and boarded pdgLive.
For example, the same is true for Christine next to Xu Yun, with her head buried in her phone.
at the same time.
Zhao Zhengguo, sitting on the other side of the fourth row, was also introducing some information to the acquaintances around him with a smile.
Being able to be mentioned in public on this occasion is an honor worth boasting for a lifetime.
When you meet someone who likes to work around, Bao Buqi will engrave a QR code on the tombstone, so that others can see this content with a scan.
After about half a minute.
Academician Pan looked at the audience again, and after guessing that most scholars had seen it, he continued:
"As you can see, this particle belongs to a type of gauge hyperon. From the data point of view, it is probably the result of an ordinary journal in the first district."
"But more than half a month later, one of my students, Xu Yun, accidentally discovered a situation when he was studying this hyperon."
"He found that the energy level of this ∧ hyperon seemed a bit strange, so with the assistance of the Aurora System of the Chinese Academy of Sciences, he calculated a special probability orbit."
"Then academician Zhao Zhengguo and I discovered a particle named 'solitary point particle' based on this orbit, which is"
"The dark matter particle we are going to announce at this press conference."
Academician Pan finished speaking.
The screen on the big screen behind him instantly changed to .
Xu Yun's headshot.
A few seconds passed.
Christine beside Xu Yun suddenly turned her head and looked at Xu Yun in surprise:
"Hey, Xu, you haven't graduated yet, are you a student?"
“.”
Xu Yun glanced at the girl with a strange expression, is this a matter of age and status?
At this time, shouldn’t you ask questions like [You are actually related to this matter] or [Did you really calculate the probability trajectory of a particle]?
This girl's brain circuit is a bit strange
But even though his heart was full of flaws, Xu Yun still answered obediently:
"Well, I'm still a student—doing my Ph.D. in physics in a few months."
Kristen was silent for a moment, then quietly asked:
"how old are you?"
Xu Yun was stared at by this girl inexplicably and a little terrified, just like a Fujianese seeing a Cantonese:
"24 years old last year, a graduate student."
Kristen looked at him for a few more seconds, then his shoulders collapsed, and he let out a sullen breath:
"Damn it, it's actually younger than me, all geniuses go to hell!"
Xu Yun: "."
Can you ask a question other than age? Hey!
Between speaking.
Xu Yun's mobile phone, which had been turned to silent in his trouser pocket, suddenly vibrated.
Seeing this, Xu Yun took out his mobile phone to have a look, and found that many people had sent him WeChat messages.
Of course.
Scientists like Qiu Sheng who had a lot of contact with Xu Yun basically already knew the situation, so most of the people who sent WeChat at this time were some friends outside the University of Science and Technology.
For example, the message sender at the top is Chen Shanshan, the cockroach girl I just met in the car:
【Complicated mood. JPG, Dr. Xiao Xu, you lied to me! ! 】
Xu Yun immediately replied:
【When did I lie to you? Didn’t I say that I calculated the dark matter? (dog head)]
Chen Shanshan:
【.You wait for me】
Other than that.
Gu Qunqing from the company, Academician Li Ning, and Lin Zhenhua from far away in Yongcheng also sent messages of congratulations or praise.
But soon.
Xu Yun's good mood was dispelled by a barrage screenshot of the live broadcast room sent by Chen Shanshan again.
From this picture, we can see that the barrage in the live broadcast room is now uniform as never before:
【Fuck, Hina! ! 】
Xu Yun: "?????"
【Fuck, xxxx】
This is a barrage format that has gradually become popular in the past two years. It is generally seen in game live broadcasts.
When a certain player has a bright eye or a cross operation, the barrage will refresh the screen with a word that can describe the player's portrait.
Such as Fuck Ice, Fuck Fly, Fuck Yuan, etc.
As for the purpose of Chen Shanshan posting this screenshot
Obviously, it is to hurt each other.
While Xu Yun was looking at the message on his phone.
Academician Pan on the stage also continued to talk:
"According to our detection, this lone particle belongs to the partner of the 4685∧ hyperon in nature, and its spin is a semi-odd number."
"The measurement result of the decay parameter is 0.633±0.002, and the observed magnitude of the interaction with the 4685∧ hyperon is about."
"140Mev."
Hear the number.
Suddenly there was a commotion from the audience.
Mentioned earlier.
The attribute of spin belongs to the intrinsic degree of freedom of the particle.
According to the Pauli Exclusion Principle.
If two identical fermions have exactly the same wave function, then the distribution probability density given by their overlapping wave function is 0.
So fermions can only have half-odd spins, that is, 1/2, 3/2, 5/2, 7/2 and so on.
Electrons, protons, neutrons, and baryons are all fermions.
Mesons, photons, weak gluons, and Higgs particles all belong to bosons, and their spins are integers.
The value of 140 Mev belongs to the category of electrically neutral mesons, but it has the spin of fermions
It took Xu Yun a lot of time to think about this question, but don't forget that all of the people present today are top leaders in the industry.
So fast.
Except for a small number of bastards.
More than 95% of the scholars have subconsciously produced a concept:
There is something wrong with the way this particle moves!
It's not walking or drifting, it's
Flashing!
More critically.
Everyone already knows that the results to be released at the press conference are related to dark matter, that is, they have prepared for the answer in advance.
Therefore, after a little deduction right now, many bigwigs have confirmed another thing:
This lone point particle
Kinetic energy is less than the corresponding static energy.
This
It is one of the most important intrinsic essences of dark matter!
Immediately after.
On the stage, Academician Pan pressed the laser pointer again, and the screen behind him changed again.
This time.
A lot of data that few students can't understand appeared on the screen.
Secondary divergence parameter: 3.445
Parity difference: 226.5 points/1 billion
Wave function derivative operator: 114514
flux value: 17.885
Exponential map generator: 1.3399596
Wave function expression: ∧>0, f(t)=Asin(ωt+), Y(x)=Csin(kx)+Dcos(kx) .
One second later.
Including Higgs and other top leaders.
Almost all physicists picked up a pen and paper when they saw this value, and quickly started the calculation.
Of course.
In stark contrast to the many scholars at the conference, there were a group of media professionals at the scene, as well as the bewildered audience outside the live broadcast room.
The expressions on their faces at this time are almost all of the same thought:
What can these numbers calculate?
Of course.
Professionals proficient in high-energy physics are not many, but there are also many.
For example, some employees of research institutes who cannot come, or students of corresponding majors in major universities.
and a very small number of civil sciences that do have strong professional knowledge but did not enter or did not stay in the scientific research circle due to various reasons, etc.
In addition, the test at this time is more about calculation ability than creativity.
So fast.
Instead, the answer appeared first in the barrage in the live broadcast room:
【Fuck, below 0.0004, ten times faster than WIMP? 】
Then soon.
Many people at the meeting also came up with calculation results.
For example
Edward Witten is the highest mathematical achievement in physics today.
I saw him draw a circle on the calculated result of 0.000193, with a thoughtful expression.
This value is called the oxika value, which is a simple tool for calculating electromagnetic interactions by hand.
This value is far less accurate than that detected by supercomputers or precision instruments, but it has a very special place:
It can grade dark matter.
For example, the calculated value range of hot dark matter is between 0.294 and 1.
Warm dark matter is 0.00331-0.294
Cold dark matter has no lower limit, the highest is 0.00331.
For example, the most likely WIMP particle currently has an oxika value of 0.00106.
Of course.
The above premise is that the basic data provided are accurate and there is no falsification.
In other words.
Purely from the results of written calculations.
The lone point particles discovered by the Chinese Academy of Sciences indeed meet the requirements of cold dark matter.
But as a top mathematician.
During calculation,
Edward Witten always felt that another vague thing was attracting him.
But before he had time to think about it, he was shocked back to reality by a voice behind him:
"Bridge bean sack, Mr. Pan, how can you prove that your values are accurate?"
I've been busy all night and slipped away to sleep
The good news is that grandma and grandma are in better condition. The bad news is that grandpa is also hospitalized, with milder symptoms than grandma. The hospitalization is because both elderly people are in the hospital so that they can be taken care of together.
But I'm afraid he never thought in his life that he would end up in a pediatric ward at the age of 96.
