Chapter 103 The hanging heart finally died When you are young, you compete in academics; when you are old, you start competing as students. Jiao Mingwu has no other pursuit now, he just wants to find a perfect successor. Xu Qingzhou has reached such a level as a freshman, so his future is limitless. Gu Zhizhong said with a smile: "Don't tell me, I really have this plan." "Old Gu, you already have several proud students. I finally met such a good seedling. Do you have the nerve to snatch it away?" Jiao Mingwu was not in the mood to drink tea. Seeing his old friend getting anxious, Gu Zhizhong waved his hand and said soothingly, "She is only a freshman, and it is still early for her to go to graduate school. It is better for the two of us not to worry about her for now." "Besides, Xu Qingzhou's heart is still not calm right now, he needs to exercise first." "Impulsive? Young people should be more impetuous. Otherwise, do they have to be like us old guys in our 50s and 60s when they are only 18 or 19 years old?" Jiao Mingwu and Gu Zhizhong have different views. Gu Zhizhong smiled and shook his head. If he was a little more energetic, he wouldn't have to worry so much. With a sigh, he asked, "Do you know what he is studying recently? Cramer's conjecture."
"What are you researching?" Jiao Mingwu was stunned for a moment, wondering if he was too old and must have heard it wrongly. Gu Zhizhong nodded helplessly: "Yes, this little guy is now working on the Cramer conjecture." Now, it was Jiao Mingwu's turn to remain silent. After taking a sip of tea, he nodded and said with a wry smile, "That's indeed a bit youthful." Cramer guessed. If you rank difficult math problems. The first tier includes seven world-class problems, namely the Hodge conjecture, the Poincare conjecture, the Riemann hypothesis, the Yang-Mills existence and the mass gap, which are known as the "Seven Great Mathematical Problems of the Millennium". The solver of each problem can receive a prize of US$100 million, and they are also the hot topics of research in the current mathematical community. The second tier is definitely the three most difficult mathematical problems in the modern world, namely Fermat's Last Theorem, Goldbach's conjecture, and the four color problem. The third tier, such as the ABC conjecture, the Collatz conjecture, and the Artin conjecture, also attract mathematicians. The fourth tier, such as the honeycomb conjecture, the perfect number conjecture, etc., the proof process is slightly "simple". The fifth tier consists of some slightly more difficult math problems, and there are a lot of them. Kramer's conjecture is rather embarrassing. According to his algorithm, it is probably between the fourth and third echelons. Although this conjecture is not among the top mathematical problems and is not as popular as the Poincare conjecture and the Riemann conjecture, it is still a huge problem that has troubled many mathematicians. For nearly a hundred years, no one has solved the problem. Countless researchers have tried to prove or disprove it, but to no avail and there is no hope. As a result, this conjecture faded from people's sight. The study of the difference between adjacent prime numbers has always been a matter of great concern to number theorists, and the Cramer conjecture is about studying the problem of the difference between adjacent prime numbers, so its importance is self-evident. Some people even claim that solving the Cramer conjecture is as valuable as solving the Riemann hypothesis. However, Jiao Mingwu has always been in a good mood. He drank tea and said slowly: "It will be fine after this age. We were the same back then. I remember that when you were in your twenties, you also wanted to solve the Collatz conjecture?" "It's been decades, why are you still talking about this?" Gu Zhizhong coughed dryly and looked out the window, as if recalling the past, muttering, "It's because I've been stuck in a dead end before that I know how painful it is." Mathematicians are like a group of treasure hunters. They are deeply attracted to this mathematical puzzle and constantly analyze, reason and experiment to try to unravel the secrets behind it. Every clue discovered and every problem solved is like a victory on the treasure hunt, bringing mathematicians closer to the hidden treasure - the truth of mathematics.
In this process, the truth sometimes seems to be within reach, but after overcoming numerous difficulties and dangers, when it is about to be revealed, one finds that one has reached a dead end. This kind of despair is unacceptable to many people and can easily undermine their confidence. Gu Zhizhong laughed at himself, poured a cup of tea for his old friend, and then sighed: "However, it's good to have more adventures when you are young. Let's not be so anxious." Library, 3st floor. Xu Qingzhou sat for about half an hour, put down his pen, rubbed his wrists and rested. Opposite me, the girl was writing something with her head down. Her long eyelashes were trembling slightly, her collarbones were delicate, and there were a few strands of hair beside her forehead, which she occasionally hooked behind her ears with her hands. It looks really good. Xu Qingzhou smacked his lips. Even though he saw it often, he still felt amazed. After being stared at for a long time, Song Yao couldn't help it anymore. She looked up and asked unhappily, "Are you here to read books or to see me?" "Both." Xu Qingzhou admitted frankly, still looking at her. Song Yao ignored him and wondered when this guy became so shameless. After a short rest, Xu Qingzhou planned to drink some water and continued. He took out the cup from his bag, only to find that there was no water in the cup. Just as he was about to stand up, a white and tender hand handed him his cup. "The water heater on the third floor is broken, and we need to go to other floors to get water." Song Yao said softly, raising her chin, indicating that Xu Qingzhou could pour it into his own cup. Xu Qingzhou didn't hesitate to take it and poured half a cup into his own. The pink cup was filled with wolfberries, red dates and the like. Unlike Xu Qingzhou who just poured boiled water, the cup was quite delicate, with a hint of sweetness, refreshing. Xu Qingzhou nodded and said in a low voice: "The tea is good, give me some." Song Yao glanced at him and uttered two words: "No." "mean." "Spit out what you just drank before you say these two words." In the distance, the tall boy sighed, and his heart finally settled down. Originally he still held a glimmer of hope that these two people were just friends, but now they are drinking water from the same cup. On the third floor, like him, countless boys began to feel heartbroken. At 5:20 pm, Xu Qingzhou and Song Yao went to the Farm Restaurant for dinner. After leaving the library, Song Yao glanced at the message and said, "My other roommate wants to come over. You saw her last time, Zhang Qiong. You should remember her. She was at the student union this afternoon." Remember, how could you not remember? Xu Qingzhou narrowed his eyes. This girl scolded him severely this morning, and this time she was clamoring to come over to have dinner with them. She was probably afraid that he would "cheat" Song Yao, so she came to monitor him. The two soon arrived at the entrance of the farm cafeteria.
After a while, Zhang Qiong came in hurriedly, carrying a white schoolbag. When she arrived, she gave Xu Qingzhou a fierce look with a warning look. (End of this chapter)
