I just want to be a quiet scholar

Chapter 68 Drawing
Before going to bed at night, Shen Qi received a WeChat message from Xu Rui.

It's been almost a week since Xu Rui arrived in the capital. He entered the men's 19-meter run final of the National U6 Track and Field Games. At [-]:[-] tomorrow evening, Xu Rui will participate in the men's [-]-meter final.

Shen Qi knew that the [-]m final was very important to Xu Rui, which was related to Xu Rui's future.

"Tomorrow at 18:30, I'll be there on time to witness your [-]m championship." Shen Qi replied with a message, and then went to sleep.

The next day, the teaching of the Math Camp continued.

The teacher is Qian Fang, who lectures on ordinary differential equations.

Except for Shen Qi, the other 25 students were listening in the classroom.

Shen Qi was called alone into a small room of [-] square meters, just he and Sun Erxiong.

The room was extremely messy, with white paper everywhere on the table and on the floor. Most of the paper had mathematical symbols or geometric figures written on it.All kinds of math books are scattered in every corner, rulers and compasses can be seen everywhere, bang, Shen Qi kicked a ruler as soon as he entered the room.

It was clear that it was broad daylight, but the curtains in the room blocked the light, and the only electrical appliances in the room were the fluorescent lamps hanging on the ceiling.

There was a small blackboard in the corner, and white chalk left a mark on the blackboard. This was a picture.

This painting is all composed of straight lines. From the perspective of a vertical blackboard, a corridor with a door opening extends infinitely, and the floor is interlaced with black and white, like countless chessboards lined up all the time.

Shen Qi saw this pattern for the first time, and his eyes never left the blackboard.

The smell of smoke in the room was very strong. Sun Erxiong snuffed out the Zhongnanhai cigarette between his fingers and asked Shen Qi, "How good is this painting?"

"Mr. Sun, I don't understand art, so I can't give an evaluation from the perspective of painting art, but from a geometric perspective, I like this painting on the blackboard very much. From my understanding, this painting seems to be a section of the projection line. Its composition is all straight lines, and the simplest lines outline the most complex existence." Shen Qi said.

"It seems that you have learned perspective." Sun Erxiong smiled kindly, "Outstanding painters must have a deep understanding of geometry, such as Leonardo da Vinci, Dürer and Alberti, but conversely, do outstanding geometers know Painting? Well, I think so. Shen Qi, can you paint?"

Shen Qi shook his head: "No, no, I can't be considered a scholar. At most, I can do graffiti, draw emoticons or two-dimensional cat-eared girls."

"Okay, sit down." Sun Erxiong asked Shen Qi to sit down, and said again, "Let me introduce myself formally. In addition to being an instructor at the math camp, I am also a professor in the Mathematics Department of Yan University."

"Hello, Professor Sun."

"Shen Qi, do you know why I called you over alone?"

"Tell me about your ideals in life?"

"Of course, I will talk to you about the ideals of life and the correct three views." Sun Erxiong took out a magazine from a pile of waste paper and said, "The Mathematical Innovation Newspaper sponsored by CUHK, Shen Qi, you are here. Published a professional mathematics paper in a journal entitled "Some New Solutions to Linear Inhomogeneous Differential Equations of Second Order Constant Coefficients"."

"The class is getting an axe, so I'm laughing at me." Shen Qi was a little embarrassed. In front of the professor of the Department of Mathematics at Yan University, his regular mathematics paper on ordinary differential equations was not a great achievement, even a little low.

Sun Erxiong closed the magazine and asked, "Shen Qi, let me ask you, are you a student of Zhongda University or a student of Yan University?"

Shen Qi firmly stated: "Of course I am a student of Yan University."

"Then why do you contribute to the magazine sponsored by CUHK, but you are so indifferent to Yan Da?" Sun Erxiong's face sank.

Shen Qi is still wronged: "I... I have limited skills! "Mathematical Research" is very high-end, and I am not qualified to contribute." "Mathematical Research" is a mathematical journal sponsored by Yan University, which belongs to the top one in the domestic mathematics circle. .

"Hehe, it's alright, don't be nervous, I'm joking, there is still a gap between the mathematics strength of Zhongda University and our Yanda University." Sun Erxiong was instantly amused, "Of course, with your current level of mathematics, Shen Qi, you want to let "Mathematics Research" "It is still difficult to accept your manuscript. But don't be nervous. After all, you are only 17 years old and less than 18 years old. You are so young and your future is limitless."

"Shen Qi, look, other students are receiving Xiao Qian's lectures to study differential equations in depth, and you have published a paper on differential equations in professional mathematics journals, you don't need to listen to Xiao Qian's class." Sun Erxiong said, " So I called you alone and wanted to have a long talk with you, about life, about ideals, and about your understanding of mathematics."

"That's great, Professor Sun. Maxima often has it, but Bole doesn't often have it." Shen Qi likes to exchange academic issues with professionals.

"You kid must have a perfect score for writing, hahaha." Sun Erxiong rubbed his palms and laughed, seeing Shen Qi becoming more and more pleasing to the eye.

After laughing, Sun Erxiong asked, "Have you had breakfast?"

"I ate it, soy milk fritters."

"Are you full?"

"I was full. I ate six fried dough sticks and drank three bowls of soy milk. The preferential breakfast of Yonghe soy milk at the school gate is very affordable."

"When you're full, just do the dao question. Xiaoxiaoshi is good for the stomach, which is conducive to the vigorous growth of adolescents in puberty."

"..." Shen Qixin said, why are all the professors all over the world a routine?
Sun Erxiong walked to the small blackboard, picked up the blackboard and wiped off the chalk pattern on the blackboard, then picked up a piece of chalk to make a new drawing.

Sun Erxiong's geometric drawing skills are very solid. He does not need to use a compass to draw a standard circle, at least it looks standard to the naked eye.

Immediately afterwards, Sun Erxiong made a few straight lines at will, and he did not use a ruler, so he simply pulled out a straight line.

Six straight lines form a hexagon, inscribed in a circle.

The six points inscribed in the hexagon and the circle are marked by Sun Erxiong as A, B, C, D, E, and F respectively.

"Do you understand?" Sun Erxiong asked Shen Qi.

Shen Qi nodded and shook his head: "In the sense of Euclidean geometry, I understand it, but in the field of non-Euclidean geometry I can't understand it, because the conditions given by Professor Sun are not sufficient, I don't know what Professor Sun thinks What do you want me to do?"

"Haha, it's fine if you don't understand." Sun Erxiong smiled habitually, and then continued to draw.

In the blank space on the right side of the circle and its inscribed hexagon, Sun Erxiong made three new lines, and the three lines intersected at a point, which was marked by Sun Erxiong as L.

"Based on the pattern on the left, you can complete the pattern on the right for me. I don't care if you use Euclidean geometry or non-Euclidean geometry, Shen Qi, all I want is a correct answer. Can it be done? Shen Qi ?" Sun Erxiong asked with a smile.

Shen Qi's eyebrows twisted into Sichuan characters: "Give me some time, Professor Sun, and I will do my best."

"It's okay, don't be nervous, the time and this room belong to you, you can use any drawing tools and references in this room. Well, I have to go buy pork, by the way, Shen Qi, you like to eat celery stuffing Dumplings or Chinese cabbage?" Sun Erxiong stuffed the wallet on the table into his pocket, ready to withdraw.

"Whatever." Shen Qi's eyes were fixed on the blackboard, and he dealt with the word absentmindedly.

Sun Erxiong was not happy: "You can do the questions casually, but you can never eat dumplings casually!"

Shen Qi: "Is the dumpling stuffed with chives and shrimp ok?"

"It must be possible! Wait, I will go to the vegetable market to buy ingredients, and we will eat dumplings stuffed with leeks and shrimp at noon." Sun Erxiong was happy and left the house to buy vegetables.
