I really don't want to lie down and win

"No!"

"This is about the application of the theory of relativity in subatomic physics. Find the rest mass and half-life of mesons from the stiffness before and after they pass through the medium." Xu Mang said indifferently: "They invited experts in relativistic physics..."

Cui Caoyang: ...!

unacceptable!

How can there be such a mess!

"Xiao Ling!"

"You're too much..." Cui Caoyang was only in the middle of speaking, but was stopped by Xu Mang.

Xu Mang shook his head, and said with a smile, "Don't panic, cousin, just give me 10 minutes!"

......

Chapter 554 Your identity? (3/3, add more for Bit Dark)

The conditions are very adequate.

In the basic national policy of observing the production of relativistic mesons, the trajectory of mesons in the magnetic field is a curve of a certain value, and the trajectory after the loss of energy through the medium is 0.34T, and the velocity of the slowed particle beam is measured by the time-of-flight general instrument It is 1.8X108ms.

The requirement is to calculate the rest mass and the kinetic energy before and after deceleration, and be accurate to two digits.

Most people would be stunned when they saw this kind of topic, but Xu Mang was full of enthusiasm for it. After all, he was a professor of theoretical physics, and his major was relativity and quantum mechanics. Almost no one knew these things better than him.

10 minutes,

This is Xu Mang's conservative estimate. After all, his racing calculation ability has degraded so much. Give him a reasonable concept of time to avoid embarrassment.

However... the situation was far from as difficult as Xu Mang imagined.

It only took 1 seconds to solve the calculation from the parameter calculation of the slowed particle to the trajectory momentum of the particle in the magnetic field, and finally obtained the kinetic energy E2 and E[-] of the slowed particle.

"call..."

Xu Mang let out a long breath, glanced at the terrified expressions of everyone present, and smiled calmly, "I'm sorry...it's mainly because it's too simple...I accidentally finished it ahead of time."

at this time,

Everyone was silent, looking at Xu Mang like a monster. They really 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, "Hurry up and check the answers."

"I..."

"This..." The bridesmaid was still speechless. Hearing Xu Mang calling out to her, she hurried to the side, took out her mobile phone and proofread it carefully. After she finished proofreading the answer, she was even more surprised.

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 solve it for two hours. As a result... it took less than 2 minutes for her to solve this problem, and the answer was still exactly the same.

he...

Who is he?

Why did Cao Yang invite such a monster to be his best man?

"Ha ha..."

"Oh?" Xu Mang asked with a smile, "What major did you graduate from?"

"I..."

"I'm a master's degree in the Department of Physics, majoring in optics," said the bridesmaid.

Xu Mang froze for a moment, nodded thoughtfully and said, "Oh...major in optics, so what... You should find an expert in relativity to write this topic, right? Can you help me introduce it to him? question?"

"Please tell him...if a slowed particle has half the chance of decaying after flying four meters, ask him to calculate the intrinsic half-life of the particle in its rest coordinate system, and the time at which the particle decays 50.00% before slowing down , the flying distance in the laboratory." Xu Mang said seriously.

This...

This guy is definitely not an ordinary person!

absolute!

It's not just the bridesmaids who have this idea, the groom and the groomsmen also have this idea. Although they don't know what Xu Mang is talking about, they sound tall and profound, and they can provide questions to experts and scholars. This ability ...not like something a college student should have.

"Yes... sorry, I didn't understand your question, can you write it for me?" said the bridesmaid.

"Oh well!"

moment,

Xu Mang handed over a blank paper, on which he wrote about the question he asked, about the half-life of the particle.

"Open Sesame!"

Xu Mang shouted across the door with a smile.

The bridesmaid outside the door communicated with the inside, and then the door was opened. Xu Mang and the others were safe and sound, and walked in without any obstacles, but... the groom was a little confused at this time Circle, he was still remembering what happened just now.

In less than half an hour, I came to the bride's bedroom, my God... Could it be a dream?

"Thank you Sesame!"

Xu Mang thanked the bridesmaid next to him who opened the door, and said to the bride with a smile, "Cousin...here we are! I'm your brother-in-law...Although I've become a traitor this time, don't worry, Cousin Brother-in-law dares to bully you in the future, I will be the first to stand up!"

Xiao Ling: ￣︿￣

It's this guy!

There is such a traitor in her family!

So angry!

But thinking about it from another angle, there is such a top genius in my natal family. I really didn't expect that it only took half an hour, and the difficulty of the third question was raised... Really a genius!

Although she was a little proud in her heart, she should be angry or angry, Xiaoling scolded Xu Mang with a dark face, "I said you little bastard, which cousin of mine are you dating?"

"what?"

"Yang Xiaoman!" Xu Mang asked with a smile, "Cousin, have you ever heard of it?"

Yang Xiaoman...
