Chapter 554: Your identity?

The conditions are adequate,
In the basic national policy of observing the generation of relativistic mesons, the trajectory of the meson in the magnetic field is a curve of a certain value. The trajectory after the medium loss component energy is 0.34T, and the slowed particle beam velocity is measured by the time-of-flight instrument. It is 1.8X10^8m/s.
The requirement is to calculate the static mass and the kinetic energy before and after deceleration, and be accurate to two digits.
Most people are basically confused when they see this topic, but Xu Mang is full of enthusiasm for it. After all, he is a professor of theoretical physics, and his major is the theory of relativity and quantum mechanics. Almost no one understands these better than him.
ten minutes,
This is Xu Mang's conservative estimate. After all, his racing calculation ability has degraded so much. Give a reasonable concept of time to avoid embarrassment.
However... the situation is far from being as difficult as Xu Mang had imagined.
It only took eighty seconds to solve the calculation of the parameters of the slowed particle to the momentum of the particle's trajectory in the magnetic field, and finally got the kinetic energy E1 and E2 of the slowed particle.
"call..."
Xu Mang took a long breath, glanced at the horrified expressions of everyone present, and smiled calmly: "I'm sorry...The main reason is that it's too simple... I finished it ahead of time by accident."
at this time,
Everyone was silent. They looked at Xu Mang like monsters, and couldn't imagine how this was done. He didn't look very smart either.
"How is it?" Xu Mang looked at the bridesmaid and asked with a smile, "Quickly proofread the answer."
"I..."
"This..." The bridesmaid was still in a state of speechlessness. Hearing Xu Mang shouting to herself, she hurried to the side and took out her phone to proofread it carefully. After she proofreaded the answer, she was even more surprised.
All right?
No way?
This is a question given by Xiaoling's colleague. It is a standard relativity problem. She threatened that she would not be able to play it for two hours. As a result...then she solved the problem in less than two minutes, and the answer was exactly the same.
he...
Who is he?
Why did Cao Yang invite such a monster to be his best man?
"Ha ha..."
"Huh?" Xu Mang asked with a smile, "What major did you graduate from?"
"I..."
"I am a master of physics, majoring in optics," the bridesmaid said.
Xu Mang was stunned for a moment, and nodded thoughtfully: "Oh... optics, so what... You should find an expert in relativity for this topic? Can you help me bring it to him? Questions?"
"Please tell him... if the slowed particle has a half chance of decay after flying four meters, please calculate the inherent half-life of the particle in its resting coordinate system and the percentage of the particle decay before the slowing down At 50 o'clock, the distance flying in the laboratory." Xu Mang said seriously.
This...
This guy is definitely no ordinary person!
absolute!
Not only the bridesmaids have this idea, but the groom and the best man group have this idea. Although I don’t know what Xu Mang is talking about, he feels tall and profound when he listens. It can provide experts and scholars with questions. This ability ...Not like what college students should have.
"Ye... I'm sorry, I didn't understand your question, can you write it to me?" the bridesmaid said.
"Oh... OK!"
moment,
Xu Mang handed in a blank sheet of paper on which he wrote about the half-life of particles.
"Open Sesame!"
Xu Mang shouted at the opposite side of the door with a smile.
As the bridesmaid outside the door communicated with the inside, and then the door was opened, Xu Mang and the others went in without any obstruction, but...the bridegroom was a little confused at this time Circle, he is still remembering what happened just now.
In less than half an hour, I came to the bride's bedroom, my goodness...could you be dreaming?
"Thank you Sesame!"
Xu Mang said thank you to the bridesmaid who opened the door, and smiled and said to the bride: "Cousin... we are coming! I am your brother-in-law... Although this time I'm a traitor, don't worry. Brother-in-law dare to bully you in the future, I will be the first to stand up!"
Xiaoling: (￣︿￣)
It's this guy!
There is such a traitor in the family!
So angry!
But thinking about it from another angle, there is such a top genius in my mother's family. I really didn't expect that, after only half an hour, the third problem was still improved... really a genius!
Although there is a little pride in her heart, she should be angry or angry. Xiaoling scolded Xu Mang with a dark face: "I said you bastard, which cousin is you and me?"
"what?"
"Yang Xiaoman!" Xu Mang asked with a smile, "Have my cousin ever heard of it?"
Yang Xiaoman...
Xiaoman? !
After Xu Mang's reminder, Xiaoling remembered who it was, and the memory of Xiaoman flooded like a flood.
"Little Man!"
"I gave her a make-up lesson when she was a child, but I didn't expect to... have already made a boyfriend." Xiaoling sighed, her expression gradually began to be melancholy, but soon she returned to reality. It is not time to admit her.
"Cough!"
"Your name..."
"Cousin, call me Xiao Xu."
"Oh..." Xiaoling nodded, and said with a serious face: "Xu...Although he helped your cousin-in-law pass three levels, your cousin's level is particularly difficult. Let's say in advance...Cousin This level increases the difficulty, you need to solve two difficult problems."
At this time,
Cui Caoyang became unhappy, and said to his untimely wife: "Xiaoling...Xiao Xu is a guest. How can you bully him like this?"
"Cousin-in-law!"
"Don't panic... It's yours." Xu Mang said with a smile: "Don't worry... I am basically invincible in China, and I have a relatively large influence in the world, right? Two puzzles... Ten puzzles can also be won!"
Xiaoling glanced at Xu Mang, and said angrily: "Don't brag, your cousin has a very stubborn temper, and it might really give you ten questions."
"Ha ha..."
"I was playing around." Xu Mang said awkwardly and politely: "Your people are all like this... Xiaoman is also like that, always pales in a hurry."
Xiaoling glanced at Xu Mang irritably. This guy seemed addicted to being a traitor. When she had the opportunity to talk to Xiaoman, she didn't take her cousin seriously.
"No kidding!"
"Cousin...please ask the question. My cousin and I are in a hurry." Xu Mang said solemnly, "I will try to end this in ten minutes."
Xiaoling:? ? ?
you...
Cousin don't want face?
It took less than half an hour to enter the bride's bedroom. Fortunately, everyone was on the scene. If this were known by the maiden family, wouldn't Fang Fang laugh out.
"give!"
"See if you can solve it in ten minutes!" Xiaoling said angrily.
Get the title,
Xu Mang glanced at it with Yu Guang. The first topic was about quantum mechanics, about the selection rule of the atomic state that absorbs or emits a photon in the action of electric dipole. According to the Bohr model and corresponding formula, Estimate the radius of the 2P state lifetime of the hydrogen atom, and then calculate the electron volts of the 2P state based on this value.
Topic!
The insidious and cunning thief!
If the first question is wrong, then the second question is absolutely impossible, but the first question is particularly difficult!
Xu Mang glanced at his cousin and several bridesmaids present, with the secretive expressions on their faces, he couldn't help sighing, alas... young man!
"The transition rule of the Bohr model!"
"It seems that the person who made the question... is a professor of quantum mechanics, and most people can't give such a question type." Xu Mang said with a smile: "In fact, you only need to calculate the energy level difference between the radiation work and the transition to the foundation. , This problem is basically solved."
"???"
"???"
"???"
really?
Is this guy still not a human?
Even this?
When everyone was confused, Xu Mang had already begun to write, almost as before, maintaining the highest hand speed.
After seeing Xu Mang's answering speed, my cousin Xiaoling collapsed a bit on the spot. I couldn't imagine how this was done. How could it be so fast?
Graffiti?
Performance Art?
Still acting funny?
five minutes,
In just five minutes, Xu Mang ended this question under the horrified eyes of everyone, and then he looked at the last problem. Once this is completed, today's work is over.
After reading the topic briefly, his expression was still plain but suddenly became a little frightened.
Xu Mang: Σ(°△°

)︴
This...
This is definitely not as simple as a physics problem!
From this topic, Xu Mang read another meaning. Although the person who wrote the topic carefully modified it, he could still understand some off-topic sounds from just a few words. This is an experimental process. In this magnetic field, any passing through The mysterious particles will generate a small electric field.
In turn, this will drive oscillations in the plasma, which can then be detected as evidence of the mysterious particle itself.
What Xu Mang needs to solve is to calculate the frequency of this mysterious particle.
Mysterious particles...
Ha ha!
Xu Mang probably knew what this mysterious particle was, and the whole experiment process was almost understood, but Xu Mang had to admire the person who came up with this experiment. He let the plasma play a dual role, both creating a system that allowed efficient transformation The environment provides a resonant plasmon to collect the converted energy.
Absolutely!
I don't know... whether his experiment was successful.
Thought of this,
Xu Mang showed a slight smile. This time the best man was not in vain, and he obtained such important information. This new experimental method can be applied to search for dark matter, tunable plasma... it played a big role here. !
With an excited mood, Xu Mang carried out particle frequency calculations, and calculated that he found many problems. This experimental plan seems to have a lot of flaws. If you analyze the known conditions, you can’t find a suitable solution. .
So far,
It is almost certain that this experiment is wrong.
But perhaps his ability was not good enough to solve the frequency problem of this mysterious particle, but Xu Mang quickly dispelled the idea. After all, physics reached the proficiency level, unless it exceeded the existing theoretical framework, otherwise it could not be his own cause.
At this time,
Xu Mang silently put down the black pen in his hand, raised his head and said to his cousin Xiaoling: "Cousin... there is a huge mistake in this topic. I need to talk to the person who wrote the question. He seems to have come to a misunderstanding. I'm afraid I will get deeper and deeper!"
"At the same time...I want to cooperate with him. His experimental method is very interesting. If a complete system can be established, it will greatly improve the two fields of astrophysics and high-energy particles!" Xu Mang is serious To say.
"???"
"???"
"???"
Whoops~EbookFREE.me~ This is so pretending to be... fresh and refined!
He even questioned the head of the physics department of Suzhou University!
Also cooperate!
Are you crazy?
"Cough!"
"Xu...Don't make trouble!" Cousin Xiaoling said embarrassingly: "To tell you the truth, this is a topic given by the dean of the Department of Physics of Suzhou University, and your cousin and me... are the lecturer of the Department of Physics, we The head of the department is usually very busy... and... what capacity do you use to talk to him about problems and cooperation?"
Xu Mang silently took off his glasses and said with a smile: "As deputy director of the Department of Physics, Fuda, professor of theoretical physics, authoritative experts in the fields of astrophysics, superconductivity, quantum mechanics, optics, materials science, etc."
