Chapter 754 756【Everyone in the world is as black as a mother】


    After the parent-teacher meeting was over, Pei Yin came home and went to his son''s room.


    Xiang Nan is writing his graduation thesis, and he is preparing to defend his thesis this year.


    The average student has to worry about writing a paper. They collect information, revise it repeatedly, check and remove duplicates. If they don’t work hard for half a year, they will not be able to pass the test at all.


    Comparatively, it is much easier for Xiang Nan to write a paper.


    ?The excellent papers in his mind are not vast, but at least overwhelming. There are so many.


    The paper he is currently writing, "Analysis of LIGO Gravitational Wave Data Based on General Physics", is one of the quite good papers.


    In 2016, the LIGO Scientific Collaboration and the Virgo Collaboration team announced that they had used the advanced LIGO detector to detect the gravitational wave signal from the merger of dual black holes for the first time.


    ?This discovery shocked the world and shocked the academic community.


    Xiang Nan’s paper is just riding on other people’s popularity. Research on gravitational waves had just begun, and he was in a good position to take the lead.


    …


    “Yiyi, are you busy?” Pei Yin came over and asked.


    Xiang Nan was stunned for a moment, then put away the keyboard, "I''m not busy, Mom, what''s the matter?"


    "Oh, nothing happened. I just came back from the parent-teacher meeting." Pei Yin waved her hand.


    “Then I did okay in the exam, didn’t I lose you?” Xiang Nan said with a smile.


    “No, I did very well in the exam, and my mother is very satisfied.” Pei Yin smiled.


    “That’s good.” Xiang Nan nodded.


    “Well, Yiyi, I met Lin Miaomiao’s mother again today.” Pei Yin said.


    “Mom, you don’t need to say any more, Miaomiao and I are not in puppy love.” Xiang Nan waved his hand.


    "..." Pei''s voice faltered, and it was difficult to say the words he had prepared.


    "Then you..." she hesitated for a moment.


    "We are just good friends." Xiang Nan responded, "Mom, I have a sense of propriety about your son, and I won''t do anything random."


    "Well, that''s good." Pei Yin nodded, "However, mom still hopes that you stay away from them. After all, your current task is still to study, and you can''t sacrifice for the small."


    "Don''t worry, Mom, I can''t do it." Xiang Nan smiled and said.


    Pei Yin nodded and left immediately.


    Xiang Nan couldn''t help but shake his head and lamented that Jiang Yuwen was such a waste. It had been almost half a year since he returned to China, but he still hadn''t conquered Pei Yin.


    ??If the two of them become successful, Pei Yin won''t have to keep an eye on him.


    Logically speaking, I am already a college student and will graduate from college this year, but I am still being controlled like a child, which is really unbearable.


    No wonder Qian Sanyi runs away from home in the play. It was really suffocating.


    …


    ?During the Spring Festival, Xiang Nan, Jiang Tianhao, Lin Miaomiao, and Deng Xiaoqi made an appointment to have a fun day.


    ?After the Spring Festival, Lin Miaomiao, Jiang Tianhao, and Deng Xiaoqi all went to tutoring classes again.


    Xiang Nan naturally does not need to attend tutoring classes. To be honest, with his knowledge base, he would be rich enough to be a teacher.


    He checked his scores after the Spring Festival and found out that he had perfect scores in each of the twelve courses, earning 80% of credits. Added together with the previous ones, the total score is 152 points, which has almost reached the graduation level.


    ?As a result, it will be a matter of course for him to graduate in the first half of this year.


    When they learned that he was writing a thesis, Qian Shouzhong and Jiang Yuwen were very interested. “Yiyi, bring your paper, your uncle Yuwen and I will help you look at it.” Qian Shouzhong said with a smile.


    Xiang Nan nodded and handed over the paper he wrote, "Analysis of LIGO Gravitational Wave Data Based on General Physics," to them.


    “Oops, gravitational waves!” Qian Shouzhong was quite surprised when he saw it.


    ?Gravitational waves were just discovered at the beginning of this year, and Sun Tzu actually started doing research on them. 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 smiled, and then both of them started to look at each other.


    Take this paper by Xiang Nan. Based on the gravitational wave data observed by the LIGO team, he used Newtonian mechanics, dimensional analysis, and analogies between gravitational waves and electromagnetic waves to estimate the mass of the black hole and the distance from the source of the gravitational waves to the earth. The initial distance before the merger of the two black holes, as well as the total energy of radiation and other parameters.


    Connoisseurs watch the door. Although Qian Shouzhong and Jiang Yuwen are not experts in astrophysics, they know everything, and they can still distinguish the quality of papers.


    Xiang Nan used the basic methods he learned from middle school and university to calculate such cutting-edge detection data. The method was ingenious and the calculations were accurate, which fully demonstrated his solid foundation and his ability to apply it at will.


    “Well, good, good, really good.” Qian Shouzhong said with satisfaction.


    This paper, if he were to use the most stringent standards to evaluate it, would get an excellent grade.


    “Yiyi, none of my papers received such high praise from the teacher.” Jiang Yuwen also smiled.


    “Thank you, grandpa, thank you uncle Yuwen.” Xiang Nan smiled.


    …


    Winter vacation is over and back to class.


    Deng Xiaoqi’s position was suddenly transferred by Tang Yuanming. After she was transferred to the third row, there was a gap of several meters between her and Lin Miaomiao.


    “Yeah, why is this?” Xiang Nan asked in confusion.


    “It must be my mother’s fault.” Lin Miaomiao said unhappily. No one in the class was moved, only Deng Xiaoqi’s position was moved. Everyone knew it was definitely aimed at her.


    ??Tang Yuanming would definitely not do such a thing for no reason. As expected, it was Wang Shengnan who instigated it.


    "She must be worried that Xiaoqi will affect my study, so she transferred her away." She said firmly, "It''s disgusting, she has to take care of everything. She has to interfere with whoever I make friends with. She is really angry. ”


    "Okay, don''t be angry. Although Xiaoqi''s position has been moved away, your relationship should remain the same." Xiang Nan persuaded with a smile, "Your mother did go too far, but you can''t resist now. You are angry." It’s futile. Just study hard and you won’t have to look at her face again if you pass the exam.”


    "Yes." Lin Miaomiao nodded heavily after hearing this, "You are right, my mother is so overbearing and unreasonable. I invited Xiaoqi to play at home during the winter vacation, and her nose was not her nose, and her face was not her face. , makes me feel embarrassed.”


    Xiang Nan was stunned and nodded.


    Actually, this is a misunderstanding. At that time, Wang Shengnan was giving fruit to the two of them, and he happened to hear Deng Xiaoqi asking Lin Miaomiao whether she was a virgin. Lin Miaomiao said no, but Wang Shengnan was so frightened that she couldn''t sleep a wink all night.


    But actually, what Deng Xiaoqi wanted to ask was "Is she 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, so she also suspected that I was in love early."


    “Really, what did you say?” Lin Miaomiao was taken aback and asked quickly.


    "Of course I categorically deny it." Xiang Nan nodded.


    ?Lin Miaomiao''s face froze when she heard this.


    “Oh, don’t worry too much, I’m afraid this will bring you trouble.” Xiang Nan explained, “I’m already a college student, and my relationship is fair and square.


    But you still have to take the college entrance examination, and your mother''s temper is similar to mine. If she knew it by then, the world would fall apart. "


    “Yeah.” Lin Miaomiao thought for a while and nodded in agreement.


    “So work hard, and when we get into college, we won’t have to listen to them anymore.” Xiang Nan encouraged.


    "Yeah." Lin Miaomiao nodded, then blinked, "Qian Sanyi, I found that no matter what you say, you can always get back to your studies."
