Chapter 445: There was a thunder on the ground, Dr. Xu made his debut (Part 2)
"....Pluto in orbit?"
Hearing what Witten said.
Academician Pan has rich experience in press conferences and has experienced countless big and small battles. At this time, he couldn't help but show a trace of extremely obvious surprise.
What the hell is this tmd...
But soon.
Academician Pan quickly came to his senses and quickly went over Witten's words in his mind.
The flux value is too large, but the exponential mapping generator is too small?
Students who have studied particle physics should all know this.
The so-called flux value is a value proposed for the main particle...that is, the ∧4685 hyperon.
This value is somewhat similar to the bulge in particle research, but it is generally reduced to about 13TeV, and at most 20TeV.
That is to say, it is a value that can be measured directly without any other processing.
The exponential mapping generator is a bit different.
It is not directly measured like the flux value, but a mapping obtained through mathematical analysis after sampling.
for example.
As we all know.
The essence of the exponential function e^t describes a differential equation:
dy/dt=y.
The physical meaning of this equation can be interpreted as your speed is always equal to your position.
That is, the derivative of position is always equal to the size of your position.
in other words.
The length of the curve from any point p to point Exp_p(v) is equal to the length of the initial tangent vector v.
The point reached by point p walking a distance of length v along the local geodesic is the image point of the exponential mapping.
At the same time.
There is a natural biinvariant Riemannian metric on a compact Lie group, and the exponential mapping determined by this metric is consistent with the exponential mapping determined by the structure of the Lie group itself.
When the exponential mapping of the Lie group itself is limited to the matrix group, it has the same infinite series form as the complex exponential mapping.
At the same time, according to Weinberg's point of view, particles are representations of the Poincaré group.
The Poincaré group is obtained by the semi-direct product of the space-time translation group R13 and the Lorentz group SO{1,3}, and is denoted as ISO{1,3}.
The Lie algebra of this group is 10-dimensional and has a special basis.
Each is an energy generator, representing time translation symmetry.
3 momentum generators, representing space translation symmetry.
3 angular momentum generators, representing space rotational symmetry.
The inner product on Lie algebra space is the algebraic convergence of complex exponential mapping.
That is, in theory.
As long as the Lie algebra and its mapping in the dual space are established, all particles can be represented.
This concept is very simple and easy to understand, right?
In other words.
The solitary point...or the exponential mapping generator of Pangea particles should be the most accurate of all data because there is no static mass definition.
To put it harshly.
Even if there is something wrong with all the data, the exponential mapping generator will not have errors.
Of course.
The premise of the above sentence is...
In that probabilistic orbit, nothing else affects the Pangea particle.
Think of this.
Academician Pan couldn't help but glance at Witten in the audience, with some hesitation on his face.
Although the questions raised by Witten did not interfere with the results of the Academy of Science's press conference in a strict sense, but he was so interrupted that Academician Pan didn't know what to do.
Is it to interrupt Witten?
This approach is obviously inappropriate, whether it is a verbal interruption or a physical interruption.
Because Witten's problem is not an unprovoked trouble, if you rashly refuse or ask the service staff to take Witten away at this time, it will be disrespectful to Witten himself, and secondly, it will be easy for others to tell the truth.
Especially now that the Academy of Sciences is already in sight of victory, if something like this happens to Witten...
Let alone Suzuki Hiroshi and Millsap, Dabao Bei and Kennedy might both survive happily.
But what if he continues to talk?
Then the next situation will be completely beyond the control of the Academy of Sciences, and no one knows where it will go.
Just when Academician Pan was hesitant.
Hou Xingyuan's voice sounded in his ears again:
"Xiao Pan, let Witten continue talking."
"I know Witten very well. He is not the kind of person who is stupid enough to rashly disrupt things on such occasions, so he probably really discovered something."
"Anyway, what Witten is struggling with is the situation near Pangu particles. No matter what happens, it will not affect our results, so let him continue talking."
"If he is really making trouble unreasonably, these big guys at the scene will not let him do whatever he wants."
Academician Pan was stunned for two seconds and soon understood what Hou Xingyuan meant.
really.
As the ‘leader’ who was able to unify string theory despite the disputes between the five companies in the last century, and eventually became the ‘leader’ of superstring theory.
Witten's emotional intelligence will never be low.
do not forget.
He started out as a liberal arts student majoring in history, and even worked on George McGovern's presidential campaign.
The five factions of string theory at that time were like the sweet, salty, sour, and spicy tofu nao today. They were not just the affairs of one or a few people, but five huge factions.
In order for these factions to be integrated and ultimately successful, it is not just as simple as having the correct theory.
Therefore, if Witten dared to speak on such an occasion, he must have discovered something so shocking that he couldn't even care about basic etiquette.
So Academician Pan quietly tapped his ear twice to show that he was mentally confident.
Then he turned to look at Witten in the audience and asked:
"...Mr. Witten, your idea is very novel and worth exploring."
"But to make this conclusion based on just two numerical values, do you think it lacks some convincing power?"
Witten nodded when he heard this and did not deny Academician Pan's statement:
"Mr. Pan, what you said does make sense, so I would like to take the liberty of making another request."
"Can the Academy of Sciences publish the relevant formulas for calculating the probability orbit of Pangea particles, and let me meet that person..."
"The doctor who calculated the probability orbit? I have some questions I want to ask him."
The Academy of Sciences did not impose restrictions on Witten's microphone, so Witten's words spread throughout the venue in an instant.
Swish——
The words just fell.
Lu Chaoyang and Christine beside Xu Yun both turned their heads, their eyes fixed on him.
Then very quickly.
There was also a murmur at the conference site with thousands of people.
Someone is discussing the possibility of the unknown particle's existence.
Someone is discussing the probability equation of Pangea particles.
Others kept glancing towards Xu Yun...
After all, the people sitting in front and behind the tenth row are industry bosses, and in most cases, the four words "industry boss" are directly proportional to two attributes:
hairline, and...
age.
Therefore, the trio of Xu Yun, Lu Chaoyang and Christine are incompatible with their surroundings in terms of age and look extremely conspicuous.
Not to mention that Academician Pan showed Xu Yun's mugshot on the screen early in the press conference, and many surrounding attendees were still somewhat impressed by Xu Yun.
Even during the press conference, several professors cordially exchanged business cards and contact information with Xu Yun - it is unclear whether they were attracted by Xu Yun's potential or Academician Pan behind him.
He looked at the big guys around him who turned their heads to look at him from time to time.
Xu Yun suddenly looked confused:
"?????"
What's going on?
I just wanted to lie down and win in peace in the audience, and I was thinking about whether to write an online novel called "The Beginning Trains a Mentor into a Nobel Prize Winner", but why did the topic suddenly come to me?
Xu Yun felt like he was having a sweet dream about Bae Zhuhyun's long legs wrapped around his waist and his dexterous tongue licking his ears. Suddenly he woke up from his dream and found half of a cockroach covered with barbs lying beside his ear.
Long legs.....
at the same time.
After a slight pause in the barrage in the live broadcast room, a classic reproduction came again:
【Shit, Hina!】
【Choo Choo Choo!】
What Witten said was beyond everyone's expectations. Even Hou Xingyuan in the background was stunned for more than ten seconds before the instructions came:
"Xiao Pan, agree to Witten's request. We will publish the specific probability formula on the big screen. In addition..."
"Give the microphone to Xiao Xu."
Hou Xingyuan’s meaning is very clear:
The Academy of Sciences did not interrupt Witten before, and now it is even less likely to refuse Witten's request - it is not difficult to get Xu Yun to be questioned.
"...."
Academician Pan hesitated for half a second, then took a deep breath and said to Witten:
"No problem, Mr. Witten, our backend staff are already retrieving the data, and it will be displayed on the big screen behind me in a while."
After finishing speaking, Academician Pan paused, and his eyes swept over the area where Xu Yun was with some concern:
"Also... Dr. Xu Yun, please stand up."
"...."
coming!
Xu Yun's hands grasping the edge of the table suddenly tightened.
After a while.
He took two deep breaths, silently recited a few words of Xudong's blessings, and slowly stood up from his position.
Even though he lived two lives before and after, he had never seen such an exciting battle.
True.
In 1100 copies.
He once led Xiao Zhao Laosu and others to cause trouble.
In the 1850 copy.
He even showed off his skills in front of Wheat, Faraday, Gauss and others.
But Xu Yun in the dungeon already knew the direction of history, knew that his coup was a beneficial move for China, and knew that his experiments would be 100% successful.
So when it comes to exciting things in the dungeon, Xu Yun is actually somewhat inexperienced.
But today is different.
He was facing all the current big guys in 2023 except Glashow, and he didn't have much advanced knowledge in his mind.
In this situation.
Unless Xu Yun is Feng Bujue, he will be a little nervous.
But there is no choice but to bite the bullet at this time.
Then very quickly.
A staff member quickly walked to the tenth row and handed a microphone to Xu Yun.
Then when passing by Lu Chaoyang, he quietly thrust another microphone into Lu Chaoyang's hand.
It is clear.
This is a temporary backup made by the Academy of Sciences. Although it may not be useful, Lu Chaoyang still has much better experience in this area than Xu Yun.
If the situation really gets out of control, Lu Chaoyang will step forward and take Xu Yun's words.
At that time, if we cooperate with Academician Pan on the stage, we will be able to control the situation to some extent.
After Xu Yun got up.
The scene suddenly became quiet.
Even Suzuki Atsushi, the 'big villain' who came to cause trouble, couldn't help showing a hint of curiosity at this time.
After all, it is one thing for Suzuki Atsushi to be a bad person. It is undeniable that he is indeed very capable.
As a practitioner of high energy physics, if you say that he has no curiosity in his heart at this time, that is absolutely impossible.
Actually.
Even Academician Pan and Hou Xingyuan had a slight sense of expectation in their hearts, in addition to nervousness and worry.
After Xu Yun stood up.
The camera on the stage quickly split into two.
Half of them were aimed at Xu Yun, and the other half were aimed at Witten.
After a while.
Witten felt that the time was almost up, so he took the initiative and said:
"Dr. Xu Yun, may I ask...how did you derive this equation?"
