Chapter 754 Chapter 756 [Mom in the world is generally black]
After the parent meeting was over, Pei Yin came to his son's room after returning home.
Xiang Nan is writing his graduation thesis, and this year he will prepare to defend his thesis.
Ordinary students are very worried about writing a thesis. They collect information, revise it repeatedly, check and de-duplicate it.
Compared to Xiang Nan, it is much easier to write a thesis.
In his head, there are so many excellent papers, I dare not say that they are vast, at least they are overwhelming, and there are so many.
The paper he wrote now, "Analysis of LIGO Gravitational Wave Data Based on General Physics", is one of the pretty good papers.
In 2016, the LIGO Scientific Cooperation Organization and the Virgo cooperation team announced that they had used advanced LIGO detectors to detect the gravitational wave signal from the merger of double black holes for the first time.
This discovery shocked the world and shocked the academic circles.
Xiang Nan's thesis is just to catch people's enthusiasm. The research on gravitational waves has just begun, and he can just come out on top.
…
"Yi Yi, are you busy?" Pei Yin walked over and asked.
Xiang Nan was taken aback for a moment, then put away the keyboard, "I'm not busy, Mom, what's the matter?"
"Oh, it's okay, I just came back from the parent meeting." Pei Yin waved his hands.
"Then I did okay in the exam, didn't I lose you?" Xiang Nan laughed.
"No, I did very well in the exam, and my mother is very satisfied." Pei Yin smiled.
"That's good." Xiang Nan nodded.
"Well, one by one, I saw Lin Miaomiao's mother again today." Pei Yin said.
"Mom, you don't need to go on, Miaomiao and I have no puppy love." Xiang Nan waved his hand.
"..." Pei Yin froze, and it was difficult to say the words he had prepared.
"Then you..." She hesitated for a moment and said.
"We are very good friends." Xiang Nan responded, "Mom, I have a sense of propriety with your son, and I won't mess around."
"Well, that's good." Pei Yin nodded, "However, Mom still hopes that you stay away from them. After all, your task now is to study, and you can't lose the big because of small things."
"Don't worry, Mom, I won't do it." Xiang Nan smiled and said.
Pei Yin nodded and left immediately.
Xiang Nan couldn't help shaking his head, lamenting that Jiang Yuwen is such a waste. It's been almost half a year since he returned to China, so why hasn't he captured Pei Yin yet?
If the two of them are successful, Pei Yin won't have to stare at her all the time.
Logically speaking, I am already a college student, and I will be able to graduate from college this year, but I am still being controlled like a child, which is really unbearable.
No wonder Qian Sanyi has to run away from home in the play. It's really suffocating.
…
During the Spring Festival, Xiang Nan, Jiang Tianhao, Lin Miaomiao, and Deng Xiaoqi made an appointment and had a fun day.
After the Spring Festival, Lin Miaomiao, Jiang Tianhao, and Deng Xiaoqi all went to remedial classes again.
Naturally, Xiang Nan doesn't need to go to remedial classes. To be honest, with his knowledge reserve, he is more than enough to be a teacher.
He checked his grades after the Spring Festival, and found that he got 80% credits for 12 courses with full marks in all of them. Combined with the previous ones, the total score is 152 points, almost reaching the level of graduation.
Knowing that he was writing a thesis, Qian Shouzhong and Jiang Yuwen were very interested.
"Yiyi, bring your paper, and your Uncle Yuwen and I can read it for you." Qian Shouzhong laughed.
Xiang Nan nodded, and handed over his paper "Analysis of LIGO Gravitational Wave Data Based on Ordinary Physics" to them.
"Hey, gravitational waves!" Qian Shouzhong was quite surprised when he saw it.
Gravity waves were just discovered at the beginning of this year, and Sun Tzu actually started doing research. I have to say, I really know how to grasp the heat.
"Yiyi, it seems that you are really interested in astrophysics." Jiang Yuwen also laughed, and then both of them looked at it.
See Xiang Nan’s paper, based on the gravitational wave data observed by the LIGO team, he used Newtonian mechanics, dimensional analysis, and the analogy between gravitational waves and electromagnetic waves to estimate the mass of black holes, the distance from the source of gravitational waves to the earth, The initial distance before the merger of the double black holes, and the total energy of radiation and other parameters.
Experts watch the doorway. Although Qian Shouzhong and Jiang Yuwen are not experts in astrophysics, they know everything and know everything. They can still distinguish between good and bad papers.
Xiang Nan used the basic methods learned from middle school and university to calculate such cutting-edge detection data. The method is ingenious and the calculation is accurate, which fully demonstrates his solid foundation and easy application.
"Well, good, good, really good." Qian Shouzhong said with satisfaction.
This paper allows him to use the most stringent evaluation standards, and he can get an excellent.
"One by one, none of my papers got such a high evaluation from the teacher." Jiang Yuwen also laughed.
"Thank you Grandpa, thank you Uncle Yuwen." Xiang Nan laughed.
…
Winter vacation is over, back to class.
Deng Xiaoqi's position was suddenly transferred by Tang Yuanming. After she was transferred to the third row, she was several meters away from Lin Miaomiao.
"Yeah, why is that?" Xiang Nan asked in confusion.
"It must be my mother's fault." Lin Miaomiao said unhappily, no one in the class was transferred, only Deng Xiaoqi's position was transferred, and everyone knew that it must be aimed at her.
Tang Yuanming would never do such a thing for no reason. As expected, it was Wang Shengnan's suggestion.
"She must have been worried that Xiaoqi would affect my studies, so she transferred her away." She said firmly, "It's abominable. She has to take care of everything. She has to intervene in whoever I make friends with. It's really **** off." gone."
"Okay, don't be angry. Although Xiaoqi's position has been moved away, it's fine for your relationship to remain the same." Xiang Nan persuaded with a smile, "Your mother is indeed going too far, but you are powerless to resist now, so angry It's useless. You'd better study hard and pass the exam in the future, so you don't have to look at her face anymore. "
"Yeah." Lin Miaomiao nodded heavily when she heard this, "You're right, my mother is so domineering and unreasonable. I asked Xiaoqi to come over to play during the winter vacation, and her nose is not a nose, and her face is not a face. , makes me feel ashamed."
Xiang Nan was taken aback, then nodded.
Actually, this is a misunderstanding. At that time, Wang Shengnan was delivering fruit to the two of them, and happened to hear Deng Xiaoqi ask Lin Miaomiao [is she a virgin]. Lin Miaomiao said no, but Wang Shengnan was so frightened that he didn't close his eyes all night.
But in fact, what Deng Xiaoqi wanted to ask was 【Are you a Virgo】.
"Okay, don't be angry, parents are the same all over the world." Xiang Nan said with a smile, "My mother heard that you and I both chose liberal arts and worked at a radio station together. She also suspected that I had a puppy love."
"Really, what do you say?" Lin Miaomiao was taken aback and asked hastily.
"Of course I categorically deny it." Xiang Nan nodded.
When Lin Miaomiao heard this, her face froze.
"Oh, don't worry too much, I'm afraid this matter will bring you trouble." Xiang Nan explained, "I'm already a college student, and it's only natural for me to fall in love.
But you still have to take the college entrance examination, and your mother's temper is similar to mine. At that time, if she finds out, the sky will collapse. "
"Yes." Lin Miaomiao thought for a while, then nodded in agreement.
"So work hard, and when we get into college, we don't have to listen to them." Xiang Nan encouraged.
"Yes." Lin Miaomiao nodded, then blinked, "Qian Sanyi, I found that no matter what you say, you can always get back to studying."
