man thirty

"Yeah, he's the only one who connects mathematics and art. The guy who is delusional...the two are completely irreconcilable."

On the podium, Gong Youhong, who was listening to these people's words, looked a little ugly.

He slapped the table with a "bang", which immediately startled everyone.

The old man stood up, looked down at the people below, and said word by word: "Mathematics and art are not related? People who say this, I really doubt how you got into Qingbei."

"That's it, do you dare to claim to be an outstanding student in Qingbei?"

The student who had spoken before immediately lowered his head in shame, not daring to speak.But he was obviously still unconvinced, and muttered in a low voice: "Mathematics is mathematics, so analytic geometry can have something to do with art and painting, but what kind of art skills are needed..."

Gong Youhong snorted, looked at the students below, and asked, "Those who think art and mathematics have nothing to do with each other, raise your hand!"

As soon as the words fell, many students raised their hands.

Gong Youhong nodded, and then asked those students who didn't raise their hands: "Those of you who didn't raise your hands, do you think there is a relationship between the two? Or did you choose to abstain because you couldn't judge."

"Teacher, we can't judge and choose to abstain."

"That is to say, there are very few people who really think that mathematics and art are closely related. Those who think that there is a relationship can stand up and let me see." Gong Youhong said again.

not a single person.

At this time, Gong Youhong was not angry anymore. He put his hands behind his back, looked left and right, then turned to look at Lin Duan and the three uninvited guests: "Miss Fang, and this gentleman and that lady, what do you think of these two? Does it matter?"

Fang Xia shook his head.

Shen Qing also shook her head.

Only Lin Duan nodded.

Gong Youhong said "Oh", and looked at Lin Duan in surprise: "This gentleman seems to have a different opinion."

"Well. Mathematics and art are somewhat related." Lin Duan said seriously.

As soon as this remark came out, before Gong Youhong opened his mouth, someone immediately laughed.

"idiot!"

"What nonsense!"

"Killing me!"

"Who is this person, a master of the art department or an expert in the mathematics department? Or a scholar who is proficient in both? What nonsense are you talking about?"

They didn't dare to refute the master Gong Youhong, but they didn't give any face to Lin Duan, a layman who didn't know the details, and sneered unceremoniously:

"Mathematics is the study of the relationship between numbers, and art is the use of brushstrokes to record the shape of things. The only relationship between the two is when they are auctioned at auction."

"Yes, yes, the only time mathematics is used in art is when valuing artworks, haha."

Faced with the sarcasm of these people, Lin Duan shook his head, and said firmly again: "Mathematics and art are not so superficial."

Gong Youhong looked at Lin Duan from the side, and suddenly smiled and said:

"Mr. Lin, how about we make a deal. Help me teach these bastards a lesson, and I'll take you to find that Li Ning. I'm not bragging. Although that young man is not well-known in Qingbei, you want to see him. An easy thing."

As early as just now, after Lin Duan learned that Li Ning they were looking for belonged to a weirdo from the Department of Mathematics, he had no hope of hiring the latter.

There is no other reason, and the person who can get the title of weirdo in the Department of Mathematics in Qingbei is definitely not a stupid ordinary person.

The genius is on the left, the madman is on the right.

This is especially true for mathematics, a subject that can only express all things with numbers.

You may also be able to intuitively feel the geniuses of other disciplines through their research results.

But mathematics, people who can be called geniuses are absolutely rare, and it is difficult for ordinary people to understand.

Such a person may have already been arranged by the state for the follow-up life, and there are more important things to overcome.In comparison, the costume design of Fangyuan Clothing is not worth mentioning.

But Gong Youhong said at this time that he could take them to see that Li Ning.

How could Lin Duan miss this opportunity?

What if the other party is interested in the conditions he offered.

So Lin Duan nodded without hesitation: "OK. I'll give it a try."

Shen Qing on the side grabbed Lin Duan's hand nervously: "Husband... the audience is a student from Qingbei. Can you do it?"

Qingbei is one of the best universities in the country, and the students who can come here are all outstanding.

But Lin Duan comforted Shen Qing with a smile: "Don't worry. The worst thing is to lose someone. There's nothing to be embarrassed about."

"Besides, they are students in the art department, not top students in the mathematics department. I really don't have to be afraid of them."

Students of the art department are naturally not high in attainments in other subjects.And looking at the attitudes of these people, Lin Duan also felt that it was necessary for these arrogant little guys to understand the importance of humility.

So, Lin Duan stepped onto the podium and wrote a mathematical formula directly on the blackboard.

Under the bewildered eyes of the students, Lin Duan drew a standard rectangular coordinate system next to him.

"Do you know who is the inventor of the mathematical plane Cartesian coordinate system?" Lin Duan asked.

The students in the audience were stunned for a moment, and then someone replied: "It's the French mathematician Descartes."

"That's right. Before Descartes, geometry and algebra were two completely different fields. But because of the appearance of the Cartesian coordinate system, he explained geometry in an algebraic way-this is the origin of analytic geometry. And what is geometry ?”

"Geometry is used to study the structure and properties of space. To put it simply, it uses graphics and numbers to solve computational problems in our reality."

"In the seventeenth century, there was a mathematician named Descartes. He and Queen Christina of Sweden fell in love with each other. But because the age gap was too large, the King of Sweden was extremely opposed. Later, the two separated and could only communicate with each other through letters. .”

"In Descartes' last letter to the Queen of Sweden, he wrote a mathematical formula. No one knows what the formula means."

"But when the Queen of Sweden solved this mathematical formula using the Cartesian coordinate system, she understood the meaning of this letter."

While talking, Lin Duan picked up the chalk and began to solve the formula that he wrote first on the blackboard.

Sparse laughter sounded from below. The students watched Lin Duan solve the problem there, and even had the mood to tease him:

"Sir, didn't you prove the relationship between mathematics and art for us? What are you doing telling us a love story?"

"Yes, sir. Don't change the subject. Quickly explain to us the relationship between mathematics and art. You don't teach mathematics or art. Why do you study foreign history?"

"Haha, I admit that this gentleman's story is very interesting, but it has nothing to do with today's topic. Hurry up and serve the main course, I'm going to have dinner with my girlfriend."

Lin Duan didn't explain or answer, but just concentrated on solving the problem.
