Chapter 279 I will take revenge tonight!!! (33, plus more)
Originally, Yang Juan and Chen Yajun were going to visit a good friend, but because their son and daughter-in-law had returned, the couple simply turned down the evening dinner.

At this time, Yan Xiaoxi turned into a caring young wife, helping her future mother-in-law, while Chen Xiaoxin stayed in his study, solving the problem of magnetic moment in quantum electrodynamics. The email was sent to Academician Ma, but no reply has been received so far.

"mom?"

"Did grandpa ever serve in the army?"

Yan Xiaoxi asked softly while picking celery leaves.

"Yes."

"He was a veteran. He joined the army at the age of 16 and went straight to North Korea to fight the Americans. He came back about a year later, but his calf was shot and had to be amputated." Yang Juan said gently: "He always talked about his hope to see his granddaughter-in-law, but he was suddenly diagnosed with liver cancer and died a few years later."

Listening to the words of her future mother-in-law, Yan Xiaoxi pursed her lips and whispered, "Is grandpa called Yang Afu?"

Yang Juan was stunned for a moment, but she was not surprised. She thought it was her son who told her, and said with a smile, "Yes."

"actually."

"Actually, my grandfather and my maternal grandfather knew each other." Yan Xiaoxi said, "After he came back from France, my parents took him to meet my grandparents. As they were chatting, my grandfather asked him if my maternal grandfather was a veteran. Then he told my grandfather that my maternal grandfather was indeed a veteran, and he also reported the unit number at that time."

at the same time,

Yang Juan's face was filled with shock and bewilderment. With eyes wide open, she asked eagerly, "Could it be that your grandfather and Xiao Xin's grandfather are in the same army?"

Yan Xiaoxi nodded and replied softly, "Well, he was not only from the same unit, but also my grandfather's soldier and even his savior. He blocked the bullet for my grandfather. My grandfather still remembers it. After the war, my grandfather asked around for him, but he seemed to have disappeared and could not be found."

For a time,

Yang Juan didn't know what to say. This sudden news made her a little overwhelmed.

"mom"

"My grandfather likes him very much." Yan Xiaoxi said with a smile: "I feel that he cares about him much more than he cares about me."

"is it?"

Yang Juan returned to her normal state and said with a smile: "I didn't expect that you two are so destined to be together. You are simply a match made in heaven. It's a rare thing that can happen to you."

Yan Xiaoxi was like a silly wife, laughing and picking leaves diligently, mumbling, "Mom? Do you like boys or girls?"

"me?"

"I also can."

"But a girl is better. Mom has taken care of a boy before, but not a girl." Yang Juan narrowed her eyes and asked softly, "Xixi, how many children do you want to have in the future?"

Yan Xiaoxi pursed her lips and answered hesitantly, "He said that the country is now in a population crisis, the aging trend is very serious, and the overall population ratio is unbalanced, so...so he asked me to respond to the country's call and have three children."

Hearing that her daughter-in-law wanted three children, Yang Juan was instantly excited, her eyes glowing with excitement, and she even cooked with full strength, saying, "Okay, okay, three is great. As for the money, don't worry about it, mom and dad will work hard to earn it."

Yan Xiaoxi responded and stood obediently by the side to help, but in her heart she was thinking about sleeping together in the same bed tonight. The more she thought about it, the more she looked forward to it and the faster her hands moved.

the other side,
Chen Xiaoxin is still studying the problem of magnetic moment.
As the research content deepened, it extended from quantum electrodynamics to the standard model. For example, the phenomenon of the anomalous magnetic moment of the muon g-2 has been a dark cloud of physics that has troubled physicists for more than years. At this time, Chen Xiaoxin is conducting an in-depth analysis of this issue.

The so-called muon is a fundamental particle in the standard model and a second-generation electron in the electron family. Except that its mass is more than 200 times larger than that of an electron, its other properties such as spin and charge are basically the same as those of an electron. It can be said to be a heavy electron.

Carrying the same charge and having spin inside, it is equivalent to a rotating ball carrying an electric charge, and this rotation can form a magnet inside the muon, so it has a magnetic moment.

Chen Xiaoxin calculated the quantum number of spin angular momentum and found that it has a linear relationship with the magnetic moment. Since there is a linear relationship, there must be a constant.
In fact, these have been studied by others. What Chen Xiaoxin did was to replicate them. Of course, his replication was not a copycat. Theoretically, the g factor of electrons and muons is 2, and the ratio between the spin magnetic moment and the angular momentum is 2, but the experiment is not 2.
Yes
Chen Xiaoxin is perfecting the theoretical error value. In fact, the theoretical value is never 2. There are quantum fluctuations in it, which affects the error between the two.

"Hey"

“Is it systematic uncertainty or theoretical uncertainty?”

When the numerical values ​​of theory and experiment never match, a hypothesis is born. The first kind of uncertainty is caused by experimental defects, also called systematic uncertainty. The second kind of uncertainty is caused by theory, also called theoretical uncertainty.

If it is the first type, as long as science and technology continue to advance, experiments and theories will always be consistent in the end. But if it is the second type, we must continuously improve the accuracy of the theory, and at the same time put higher requirements on mathematics.

"It's over."

“It feels like we’re back to square one.”

Chen Xiaoxin pulled his hair, his brows full of pain and helplessness. He originally wanted to find the answer through the anomalous magnetic moment phenomenon of muon g-2, but ended up jumping from one pit to another. But then again, even if he found the problem of magnetic moment and gave a solution, there was no super-large particle accelerator in China, which was equivalent to handing the results to foreigners. Chen Xiaoxin would never agree to such a thing.

Unfortunately, however
Many people in the country are opposed to super-large particle accelerators.

No solution
Chen Xiaoxin thought for a long time and silently threw all the manuscripts into the trash can, including the previous ones. Instead of wasting time on this problem, it would be better to do something meaningful, such as bringing some fresh fun to a girl.

but
Will this little girl's screaming and shouting alarm the parents next door?

Thinking back to her crying voice one night in Beijing, it was really shocking. Fortunately, we stayed in a luxury suite with excellent sound insulation, otherwise... otherwise the headline of the news the next day would be
Chen Xiaoxin shrank his head, and felt a little discouraged about his expectations for someone tonight.

She's like a pig being slaughtered!
My mom might think I am domestic violence.
It was very lively during dinner.
After all, we have grown from a family of three to a family of four.

After dinner, Crouching Dragon and Phoenix Chick went for a walk outside together. Yan Xiaoxi now looked more and more like a young wife. She hugged one of his arms tightly, with a newlywed smile on her face.

"How is the research on the magnetic moment problem going?" Yan Xiaoxi asked softly.

"I have lost all my manuscripts." Chen Xiaoxin sighed and replied bitterly: "Even if I figure it out, there is no way to verify it. We lack a super-large particle accelerator."

"Then there's no way."

Yan Xiaoxi said delicately, "It's extremely expensive to make this thing. And it may be meaningless in the future. After all, high-energy physics is almost over. With the emergence of the standard model, humans have a certain understanding of the material world, and we also know three of the four forces."

"There is only one kind of gravity left, but it is still very difficult to understand gravity. The next is to unify force and mass, but there is no progress." Yan Xiaoxi paused and continued: "If we really want to build this, other scientific research will inevitably suffer a heavy blow, and there will be no money to allocate funds to other fields."

Speaking of which,
Yan Xiaoxi hesitated for a moment, then said seriously, "Stupid boy. During the Chinese New Year this year, my boss found me and talked to me about some related topics. You might as well take a look at them. He told me that when analyzing problems, we must take into account the actual situation of the country and put people's livelihood and education issues before science."

These words were like a huge rock, smashing heavily into the lake of Chen Xiaoxin's heart, instantly stirring up huge waves. Indeed, he had oversimplified the problem.

Young man.
You are still young!

"Um"

"I feel like my soul has been touched." Chen Xiaoxin smiled innocently and said, "Everything should be based on reality. There is no point in talking nonsense."

"Hehehe~"

Yan Xiaoxi smiled happily. She was worried that he would be angry, but she didn't expect him to accept it so easily. She couldn't help but hold his arm tightly and said in a coquettish voice: "When we truly enter the category of developed countries, we will be able to achieve things that we didn't dare to think of before. I believe that time will be very fast."

"necessary."

Chen Xiaoxin smiled and whispered something in her ear.

"no!"

"I'm already fine!"

Yan Xiaoxi's face, which was originally full of smiles, suddenly turned hideous, and she said angrily: "You want me to be a widow? No way!"

"Hey hey!"

"Touch it lightly."

Chen Xiaoxin quickly covered her mouth and said with embarrassment: "First of all, my room is not soundproof. Secondly, you like to yell and even cry at critical moments. If my parents hear this, they will think I am abusing you in the room."

Yan Xiaoxi rolled her eyes, with a hint of anger in her resentment, and said angrily: "Who told you to speed up without permission?"

"."

"It's obviously you. Woo woo woo."

Chen Xiaoxin's mouth was covered. Yan Xiaoxi stared at him viciously and threatened: "If you say anything about this again, I will kill you!"

Release your hands.
Yan Xiaoxi said shyly: "Then stay at my house tonight. There's no one at home anyway. Besides..."

He whispered in his ear, speaking menacingly:

"tonight."

"I want revenge!!!"
