Chapter 170 Fermat's Last Theorem (for subscription)
When Li Changqing brought Zhang Jiaye back to the hospital, Zhang Mingliang thought that Li Changqing was busy at a nearby construction site.

After hearing that Li Changqing was temporarily employed in a health center, Zhang Mingliang probably guessed that Li Changqing's identity was a village doctor. Although he thought it strange to see Li Changqing driving a luxury car, he didn't think too much about it. Chinese studies, mathematics, medicine, Fengshui, etc. have been deeply studied, and they are well-known in Guyang County and even Wen'an City!
Zhang Mingliang looked around Lijia'ao Elementary School was crowded with people, all the available space was full of people.

When the figure of Li Changqing appeared at the scene, the onlookers showed pilgrimage-like eyes, and Zhang Mingliang felt a little nervous and hopeful: "Looking at this posture, Mr. Li Changqing should be very powerful. Maybe Jiajia's illness can be cured!"

"Dad, look at Uncle Li is here!"

Zhang Jiaye stayed in Lijia'ao Primary School for a day, and was much more cheerful than when he was in the hospital. He pointed to Li Changqing and said happily.

"Hey, don't talk!"

After Li Changqing appeared, the originally noisy crowd immediately quieted down and became dignified and solemn. Zhang Mingliang was also infected by the surrounding atmosphere, stroking Zhang Jiaye's hair and exhorting him affectionately.

"Yeah!" Zhang Jiaye nodded obediently.

Li Changqing read very frankly, and read directly.

"The Master said: "Benevolence is beauty. If you choose not to benevolent, how will you know?"

"The Master said: "Those who are not benevolent cannot be in a long-term contract, nor can they be happy with their strengths.Those who are benevolent are safe and benevolent, those who know benefit from benevolence. "

"The Master said: "Only the benevolent can be good and evil. "

"The Master said: "Gou's ambition is benevolence, and there is no evil. "

……

It comes from the chapter "Liren" in "The Analects of Confucius". The straightforward meaning is that it is good to live with people with benevolence.People without benevolence cannot live in poverty for a long time, nor can they live in happiness for a long time.A benevolent person is content with the way of benevolence, while a wise person acts benevolence only when he knows that benevolence is beneficial to him.Only those with benevolence can love and hate others.If you aspire to benevolence, you will not do bad things. Even when you are in a state of flux, you will definitely act according to benevolence!

In essence, benevolence is not an external dogma, but the home and destination of human beings.

People are close to benevolence because of themselves, rely on benevolence and care for benevolence non-existently, and practice and maintain benevolence in the current situation that is constantly recurring.

Nowadays, traditional Chinese culture is being eroded and covered up, foreign cultures and ideological trends occupy the mainstream of society, and the Chinese nation is slowly losing its own foundation. A listener carves out a path to a lost spiritual home.

Zhang Mingliang heard the sound of Li Changqing reading for the first time, and he was completely immersed in the sound of the book. He felt the meaning of every sentence Li Changqing read from the bottom of his heart. He has a peach blossom-like feeling.

It turned out that a master of Chinese studies preached the principles of sages in the deep mountains and guarded the pure land of benevolent people.

Other listeners who often come to Lijiaao to listen to Li Changqing's reading also have a deeper understanding of people and benevolence, and have found their true heart in a materialistic life.

After Li Changqing read the book, the audience left in an orderly manner. Lijiaao Primary School started classes. Li Changqing taught Li Hongdou about Chinese medicine in the health center, and gave Zhang Jiaye acupuncture to temporarily control his condition during the class break. He returned after he was busy. Go to Zhongnan Mountain, take Li Changliang around the mountain, find a big rock that can match the sun, lie down and read, and supervise Li Changliang's land reclamation work by the way.

noon.

The weather is fine, blue sky and white clouds, green mountains and green waters.

After eating, Li Changqing went down the mountain and drove to Wen'an College. According to his agreement with Qiu Lexian, there was a class in the afternoon.

When Qiu Lexian hired Li Changqing at the beginning, he mainly wanted to put up a signboard for the Department of Mathematics, so Li Changqing was assigned to the Department of Mathematics. After seeing Li Changqing's level of Chinese studies, he wanted to transfer Li Changqing to the Department of Chinese, but he didn't know Li Changqing's personal wishes, so he kept Did not speak.

After Li Changqing arrived at Wen'an College, the classroom was arranged in the multi-functional lecture hall of the Department of Mathematics, which could accommodate two to three hundred students, but it was already overcrowded.

It is mainly for junior and senior courses. After hearing Li Changqing's speech at the opening ceremony, many freshmen and sophomores rushed to squeeze in the back of the classroom, and even students from other colleges were among them. Very hot.

Li Changqing's lectures to students in the Department of Mathematics naturally cannot avoid Goldbach's conjecture.

He proved Goldbach's conjecture and made a major breakthrough in the field of number theory. The Huaxia Institute of Mathematics respected him as an authority in the field of number theory. The teachers of the Department of Mathematics also sat in the front row, like students waiting for the teacher to teach.

Li Changqing did not have a lesson plan, so he wrote down a theorem directly on the blackboard: when the integer n > 2, the equation x^n + y^n = z^n about x, y, and z has no positive integer solution.

Only the teachers of the mathematics department and some senior students could understand that what Li Changqing wrote was the famous Fermat's last theorem. Algebraic number theory, a branch of number theory, was derived from the research of Fermat's last theorem.

Li Changqing started from algebraic number theory, explaining the demonstration process of Fermat's last theorem from the shallower to the deeper.

Integrating the awe-inspiring righteousness of Meixin Nigongwan during the analysis, students and teachers were inadvertently attracted by Li Changqing's words, followed Li Changqing's words to turn their thinking, and deduced the calculation step by step.

For many people, mathematics is boring and drowsy.

Even if they admired Li Changqing's name and came to the classroom to take lessons, they probably all dispersed within 10 minutes after hearing it.

But when Li Changqing was giving lectures, he used his awe-inspiring righteousness, and the whole classroom was quiet, and everyone listened attentively to Li Changqing's lecture.

Mathematical formulas and symbols appear rigid and rigid in textbooks and materials, and in Li Changqing's mouth, they are like bricks, very three-dimensional, and demonstrating Fermat's last theorem is like building a castle with bricks.

Li Changqing is like a brilliant architect, carrying out his work in an orderly manner.

"Ring Ling..."

When the bell rang for the end of get out of class, Li Changqing happened to draw a dot at the end of the formula.

Proof of Fermat's last theorem completed!
At this time, the teachers in the Department of Mathematics only have one capital letter in their minds. After Fermat’s Last Theorem was proposed, after more than 300 years of conjecture and dialectics, it was finally thoroughly proved by the English mathematician Andrew Wiles in 1995. .

With the help of various materials, they can barely see the proof process of Andrew Wiles, but they will definitely not be able to lift weights like Li Changqing with ease.

The eyes of those freshmen, sophomores, juniors, and seniors shone with inconceivable expressions. Although they could not retell the proof process, and even let them see it themselves, they still couldn’t understand it, but they did understand it just now. The whole proof process!
