Legendary Magistrate

It's unpleasant to watch! ! So depressing! ! Starting with a county magistrate is too naive! ! Not recommended to watch!

Xu Yue, whose courtesy name was Gonghe, was born around the Yonghe reign of Emperor Shun of the Han Dynasty and died in the first year of Huangchu of the Cao Wei Dynasty (220). He was a native of Donglaiye County, the founder of abacus, and a famous mathematician in ancient times. In the early years of Emperor Ling of the Han Dynasty, Xu Yue paid homage to the famous astronomer Liu Hong as his teacher. He carefully studied the calendar knowledge of Hui, Shuo, Xian, Wang, and eclipses. He assisted Liu Hong in calculating solar and lunar eclipses for the first time using Ding Shuo. He and his teacher discovered that there is an angle of about 60 between the white path (the moon's orbit plane) and the ecliptic (the sun's apparent orbit plane). After Liu Hong's death, At the end of the Eastern Han Dynasty, when all the heroes came together and the world was in chaos, Xu Yue was not disturbed by the troubled times and devoted himself to studying knowledge and diligently exploring the mysteries of nature. He developed and perfected the "Qianxiang Calendar" created by his teacher and taught it to Wuzhong Shuling Kan Ze. Two years after his death, the "Qianxiang Calendar" method was first adopted by Soochow and implemented nationwide. " In addition to studying astronomy and calendars, Xu Yue also collected a large amount of mathematical materials from my country's pre-Qin period, and wrote books such as "Nine Chapters of Sutra" and "Records of Numerology", which later became the most important part of the "Ten Books of Numerology" of the Guozijian Academy of Numerology in the Tang Dynasty. Most of the mathematical knowledge we learn today comes from this. "Nine Chapters Suanjing" is divided into nine chapters: 1. "Fang Tian" is the algorithm for finding the area of the four fraction sums; 2. "Corn" is the algorithm for finding volume; 3. "Decapoint" is the algorithm of distribution ratio; 4. "Shao Guang" means square root and cube root; 5. "Shang Gong" is the algorithm for finding volume; 6. "Equalized Transport" is an algorithm for managing the equalized burden of grain transportation; 7. "Profit and Deficiency" is the algorithm of the profit and loss lamp; 8. "Equations" means solutions to linear equations and positive and negative numbers; 9. "Pythagorean" is the Pythagorean theorem; Among them, negative numbers, fractional calculations and linear equation solutions are among the famous ancient mathematical works in the world. They have been translated into many languages and have made great contributions to mathematics in the world. Xu Yue introduced 14 calculation methods including abacus, abacus, mental arithmetic and other various calculation methods in the form of a question and answer session with his teacher Liu Hong in "Records of Numerology". It is the earliest work recording the word "abacus" in our country and in the history of the world. Although the traveling abacus he recorded is not the same as the current stringed bead abacus, it is the ancestor of modern abacus. Modern abacus went through continuous improvement for more than a thousand years after Xu Yue, and was finally finalized in the Yuan Dynasty. Xu Yue is the pioneer in the history of abacus in the world.

Well written. I am a newbie and I have followed your books.

No comments, no reading! Your comments are the greatest support for the author, please enter your comments here

I think there are still too few trustworthy subordinates in Fengzhi County. If we want to launch a major operation, I'm afraid we won't be able to catch them all in one go.

I hope this story can start well and end well. Don't follow Mu Yi's example and go down the evil path and violate a good subject matter.

I learned well. In fact, I personally think it would be better if Yue died of poisoning there.

I don't have much literary talent, but I still have some ideas after reading a big book. (1) After the protagonist saw the beauty of the young lady from the Yang family, Brother Zhu went up to chat with her, which almost made me have the urge to smash the computer. I thought it was another idiotic article, but I got through it. The rest of the story was good. It can be understood that I have just traveled through time and haven't recovered yet. (2) Regarding some nicknames, they are "Black Tornado", "Timely Rain", "Xiao Li Guang" and the author, please just come up with "Nosy XX" and I almost spit out a mouthful of old blood. . . . . . (3) Since the author's introduction mentions puzzle games, let's use puzzle games as the theme, supplemented by life flow and so on. Women should try not to mess around. . . . . . At first I thought she was a concubine that my wife had reserved before she was married. . . . . . The Qidian novel is not a pornographic novel, there is no leakage at all. I don't know what the fun is in getting a bunch of women. If the author dares to be as explicit and detailed as a pornographic novel, I won't say anything even if your chapters are written in a vase. (4) As a ZZ person, I tend to be half-fifty-cent or fifty-cent. I personally hope that the author will not appear to be "borrowing the past to satirize the present". After all, not everyone is Lu Xun. Today's society is not like the Republic of China where naked people cannibalize people. (Fruit fans, don't troll me... I'm too lazy to troll you) That's all. . . Did the author completely ignore the fourth article? -?

Develop ports to run sea-going ships and import large quantities of Japanese copper

I feel uncomfortable if I don't complain.
