Superstring theory

Lin Zhixia's tenth birthday is September 24, 2004.

　　 Jiang Yubai firmly remembered this date.

　　 Prior to this, Jiang Yubai had a new tutor-this teacher graduated from the best university in the province. This university ranks among the top five in the country, and its School of Mathematical Sciences is among the top three in the country.

　　 Jiang Yubai asked the new teacher: "Have you studied physics?"

Teacher 　　 pushed the glasses on the bridge of his nose: "I went to a competition class in high school. I participated in math and physics competitions."

　　 "Very good," Jiang Yubai nodded and applauded, "Please recommend me the most difficult physics competition exercise book. It must be the most difficult, the latest published, not the ordinary difficulty."

Teacher 　　 questioned: "The level of high school competition? You may not be able to read... What are you buying?"

Jiang Yubai held the pen and tapped on the page: "I need one, the most difficult physics competition exercise book in history." He deliberately imitated the tone of his father's words: "I'm sorry, it involves personal privacy. , I cannot answer your question in detail."

　　 Teacher is full of confusion. But he is a professional mathematics tutor after all. Soon, he recommended to Jiang Yubai a series of "International Young Physicists Competition", "Princeton University Physics Competition", "British Physics Challenge", "Canada Waterloo Newton Physics Competition" and "Chinese Physics Olympiad". Excellent series of physics exercises.

　　 These names, they sound very difficult! Jiang Yubai cheered up and worked hard.

　　 He looked at the list of books he had made, and had a foreboding that Lin Zhixia would be crying and retire in the face of difficulties.

　　 On September 24, 2004, Jiang Yubai carried a schoolbag and picked up a heavy handbag.

　　 He successfully collected a summary of all the exercises-Chinese and English. Moreover, Jiang Yubai spent the whole night tearing up the answers from all the books.

　　 Yes, he tore up the answer.

　　 He knew that this was an immoral, dishonest, and dishonest behavior. His conscience was tortured.

　　 In the end, it was his desire to win and lose slightly to gain the upper hand.

　　 At 7:17 in the morning of September 24, Jiang Yubai carried a heavy bag and slowly stepped into the classroom of the fourth grade (1) class. His expression does not seem the slightest difference in the weekdays. But his heart was already surging and the waves were surging.

　　 He guessed that Lin Zhixia might cry.

　　 He hesitated in placing the exercise book.

　　 If she cries, what should he do?

　　 He can't make him cry at the same table, let alone be cruel. He should be a good man. When he grows up, he will be a good man.

　　 Jiang Yubai glanced sideways at Lin Zhixia.

　　 Lin Zhixia's cheeks were white and red, and the bright morning light made her eyes galaxy. She opened her notebook and was writing "Human Observation Diary".

　　 Lin Zhixia wrote: September 24, 2004, I will continue to accumulate materials today. My deskmate Jiang Yubai is still studying the theory of plural numbers. He did not really understand the vector meaning of the complex number space. It may take some time before he can apply mathematical tools to practical theories. Yesterday I described my understanding of superstring theory to Jiang Yubai, and I found that Jiang Yubai did not know anything about the famous general theory of relativity...

　　 The four characters "know nothing" stinged Jiang Yubai's eyes.

　　 Put away your pity. Jiang Yubai warned himself. Pity to the enemy is cruel to oneself.

　　 He clenched his fists, made up his mind, and shouted in a cold voice like hell: "Lin Zhixia."

　　 Lin Zhixia writes quickly, writing like a god. She asked casually: "What's the matter?"

　　 Jiang Yubai emptied his handbag on the table.

"Chinese Physics Olympiad", "International Young Physicist Competition", "Princeton University Physics Competition", "British Physics Challenge" and so on. The most difficult international physics competition topics in history are presented in this moment. In the eyes of Lin Zhixia.

　　 "All for you," Jiang Yubai said slowly, like a demon, "I tore up all the answers."

　　 Lin Zhixia raised her head and stared into his eyes.

　　 He added: "Every book is torn, torn cleanly."

　　 Just as Jiang Yubai expected, Lin Zhixia's eyes were filled with mist, tears accumulated, and her eyes were filled.

　　 The roots of her ears also began to turn red, like the sunset of midsummer. Even her whole person trembled slightly, as if she had turned into a fish caught by the lake. Her nose was sour and she couldn't help crying, the more she cried, the more she couldn't stop. Beautiful eyes were covered with tears, and she complained to him in a pitiful tone: "I know I shouldn't cry, but, but, some emotions can't be controlled...Last week, you asked me when my birthday was. I thought about whether you want to give me a gift... the first time I received a birthday gift from a classmate... never before... no one treats me like this..."

　　 Jiang Yubai did not expect her reaction to be so big.

　　 He has lost the joy of winning.

　　 He stammered: "Yes, I'm sorry, Lin Zhixia, the answer was not thrown away, I..."

　　 I will bring you all the answers this afternoon.

Before this sentence was spoken, Lin Zhixia wiped away her tears and said to him, "Thank you, thank you! This is the best birthday present I have ever received! Jiang Yubai, you are my best friend! You will always be my best friend! Jiang Yubai! You are so kind!"

　　 Jiang Yubai was a little confused.

Lin Zhixia was very happy and even held his wrist: "I never read the answers...I don't like to read the answers. I hate the answers. Because the ideas of the answers are completely different from mine. I just need to find the problem. Questions can help me think, and the process of thinking is the most important thing. You understand me well, you really understand me well. Thank you for tearing up all the answers for me! Thank you, Jiang Yubai."

　　 Jiang Yubai withdrew his hand. He quietly looked at the desk top, and finally understood that Lin Zhixia was crying with joy just now.

　　 Lin Zhixia's eyes are red, like a rabbit. She is still chattering: "Without the answer, the book has become lighter. I am so happy! I will continue to teach you superstring theory today! Yesterday we said that superstring theory combines general relativity and quantum mechanics! You know' Tachyon? Tachyon refers to a subatomic particle that moves faster than the speed of light in theoretical physics. It will never slow down to a speed close to the speed of light... The supersymmetry of superstring theory refers to Is the symmetry between fermions and bosons interesting? Can you imagine the connection between supersymmetry and tachyon..."

　　 Jiang Yubai grabbed the handbag and stuffed it into Lin Zhixia's drawer. He said, "I'll install books for you."

　　 Lin Zhixia nodded: "Okay."

　　 Jiang Yubai supported his cheek with one hand and muttered to himself: "I will not lose."

　　 Lin Zhixia wondered: "What did you lose?"

　　 Jiang surpasses the white taboo as deep as possible. He will not let Lin Zhixia realize that this is a competitive crisis too soon.

　　 Lin Zhixia's tears were still wet on her face. She took out a napkin and wiped her face. She was sitting in the corner of the last row, and none of the classmates in the front row noticed her violent mood swings. After a while, Lin Zhixia seemed to be calm again. Jiang Yubai looked at the world outside the window and changed the subject: "A plane flew over the sky."

　　 Lin Zhixia said: "I haven't taken a plane yet."

　　 Jiang Yubai was surprised: "Really?"

　　 "What is it like to fly by plane?" Lin Zhixia asked him for advice.

　　 At this time, class leader Dong Sunqi, who also holds the position of "mathematics class representative", is collecting homework.

　　 Dong Sunqi stood beside Jiang Yubai and gave important instructions to each group: "Those who didn't hand in their homework! Remember all their names! No discussion!"

　　 Then, Dong Sunqi answered Lin Zhixia's question: "Before taking the plane, you have to buy a ticket. When you enter the airport, you have to choose a seat at the check-in counter..."

　　 Jiang Yubai interrupted Dong Sunqi's words: "Private jets do not need to buy tickets."

　　 Dong Sunqi holding a stack of math homework books, condescendingly examine Jiang Yubai: "Do you have a private jet at home?"

　　 Jiang Yubai humbly and low-key replied: "I didn't buy it."

　　 "Nonsense," Dong Sunqi questioned, "How can you buy a plane?"

　　 Jiang Yubai was inspired by him to be competitive: "When I grow up, I will buy it myself."

　　 Dong Sunqi immediately compared and said: "I will buy too! I will buy ten!"

　　 Zhou Bufeng sitting in the front row joined the comparison: "I want 20 Boeing 747s."

　　 Dong Sunqi put down his math homework and devoted himself to the battle: "I want to buy 30 domestically-made J-8 fighters, 30 American-made Lightning fighters! I also want aircraft carriers, guided missile destroyers, intercontinental cruise missiles..."

　　 "Why do you want these things?" Jiang Yubai asked him.

　　 Dong Sun Qi was stunned, unable to tell why.

　　 Jiang Yubai sneered indifferently: "Do you think you are playing "Age of Empires"?"

　　 "Age of Empires" is a computer game popular among boys in the school. Players accumulate resources such as gold, food, timber, population, produce troops and military weapons, and fight against the enemy in order to obtain the ultimate victory.

　　 Dong Sunqi was choked by Jiang Yubai's words. He walked to the side and began to urge everyone to hand in their homework.

When 　　 received homework, Dong Sunqi's brain did not stop working. He finally figured out a way. So he ran back to Jiang Yubai and solemnly declared: "Jiang Yubai, will you come to my house on weekends? I have a computer at home! It is loaded with "Age of Empires". I also have a DVD player, "Slam Dunk", Have you seen the complete discs of "Inuyasha", "Pokemon", and "Detective Conan"?"

　　 "I have watched "Inuyasha", "Pokemon" and "Detective Conan"!" Lin Zhixia snapped the table and answered in surprise.

　　 Jiang Yubai thought that Lin Zhixia was going to Dong Sunqi's house as a guest. He immediately turned his head and looked at Lin Zhixia: "I also have animation discs at home, you come to my home."

　　 Lin Zhixia was startled.

　　 Jiang Yubai said: "I have everything in my house."

　　 Actually, Jiang Yubai's driver, Manor, and Aston Martin are all well-known throughout the year.

　　 The sixth-grade senior claimed that his parents both worked in Jiang's company. The senior also said that Jiang Yubai's grandfather is a figure on the Hurun Rich List, and Jiang Yubai's mother family runs the province's building materials, construction and steel industry.

　　 Senior's description is profound and difficult to understand.

　　 The students in the fourth grade (1) class know more or less that Jiang Yubai is very rich.

　　 Jiang Yubai's nickname became "the richest man in the class".

　　 So, what would the home of "the richest man in the class" Jiang Yubai look like?

　　 Dong Sun Qi wanted to find out. He bent down and put his arms around Jiang Yubai's shoulders, and asked him in a "good brother" tone: "Can I go to your house to play?"

　　Jiang Yubai was about to refuse, Dong Sunqi said abruptly: "Jiang Yubai, don't you just let girls go to your house to play? Don't look down on boys. You are a boy yourself."

　　 "Okay." Jiang Yubai invited four people in one breath. They are his deskmate Lin Zhixia, monitor Dong Sunqi, Gan Shuli sitting in front of Lin Zhixia, and his friend Ding Yan.

　　 Strangely, Zhou Bufeng also turned around, sitting on the chair and shaking back and forth. His eyes have been focused on Jiang Yubai, and he seems to be waiting for Jiang Yubai's invitation. However, Jiang Yubai swears from the bottom of his heart: I will never invite him.

　　*

　　 On Sunday morning at 6:00 this week, Jiang Yubai got up.

　　 He followed the rules of life, went to bed at 8:30, got up at 6 o'clock, then washed, morning exercises, bathed, and eaten.

　　 At 7:30 in the morning, the piano teacher came over to give Jiang Yubai a lesson.

　　 While Jiang Yubai was playing the piano, he suddenly thought, could he play a piece in front of Lin Zhixia? Can Lin Zhixia understand the tune? If she doesn't understand, he will make a comeback.

　　 has a long lingering sound, he pressed the last note and constructed a blueprint in his mind.

　　 At 10:30 in the morning, Jiang Yubai was sober thinking and neatly dressed. He left his bedroom, walked downstairs, and stood in front of a floor-to-ceiling window, waiting patiently for his classmates.

　　 The lawn outside the window is endless, the road is wide, and the street lights are towering.

　　 Jiang Yubai's home sent two cars to bring classmates from different communities in the city. When he was studying in Singapore, Jiang Yubai never invited anyone to his home. He returned to school for less than a month, but he quickly integrated into the class, into the group, and had many friends. This made Jiang Yubai's mother very pleased.

　　 Dad said: "If one party raises one person, Jiang Yubai is still more comfortable in China."

　　 Mom also said: "Our son will make decisions in the future and he will definitely have to deal with people who teach and teach. He can't just know one class in Singapore."

　　 Jiang Yubai's father sat on a bar-style terrace on the top floor of the manor. He picked up the glass and glanced at his watch again: "I should leave. This time I will stay in Beijing for half a month, and then go to Shanghai and Suzhou again. The schedule is full..."

　　 his wife smiled and urged: "Okay, you go quickly."

　　 The two of them kissed on the breezy terrace.

　　 Until the wind stops.

　　 Two cars came in on the ground. After the car stopped, five children walked down-two girls and three boys.

　　 Jiang Yubai remembered that he only invited four people, why did five appear?

　　 He scanned the group of classmates, besides Lin Zhixia, Gan Shuli, Ding Yan, Dong Sunqi, there was also a boy he had never seen before. The boy stepped forward and introduced himself: "I am Dong Sunqi's neighbor. I am thirteen years old and my name is Nie Tianqing."

　　 Nie Tianqing looks handsome, tall and thin. He was wearing the uniform of the No. 1 Middle School in the city and standing still on the green lawn.

　　 He claims to be Dong Sunqi's neighbor.

　　 Jiang Yubai's emotionless eyes fell on Dong Sunqi.

　　 Dong Sunqi quickly introduced: "Nie Tianqing is the same school who graduated from elementary school! He is on the second year of junior high school this year! His family moved upstairs to my house the year before, and I often play video games with him...

　　 Dong Sunqi put on Jiang Yubai's shoulders: "The richest man in Jiang, I will bring someone to play, you give me a face? Next time, you go to my house, you can bring a few people."
