Chapter 557: Complementing metaphysics
It is said that Chen Long worked hard all night and gave up the tempting idea of tracking Yue Ji deep into the enemy's cave. He finally said goodbye to Erhe Shao Ge and returned to the greenhouse to rest. He deeply lamented that he came to rescue his beloved wife Diao Chan, but ended up in Xiliang. We are stuck in the great quagmire, unable to extricate ourselves, and will never return to the Central Plains!
When will I march with my spear and gallop on my horse, and conquer the Xiliang Gobi Desert?
When Chen Long woke up and saw the sky was getting bright outside the greenhouse, he remembered his date with Jiang Wei and immediately got up to pack his clothes. Suddenly he smelled a sour odor all over his body and felt the beard on his chin. He knew that he had not taken a good bath for several days. . Seeing that there were only two special operations team members guarding the door in silence, and knowing that all the team members were performing surveillance missions overnight, I yelled sorry in my heart, but I didn't care much anymore, and said to the uglier one among them: "Look here. Home."
Appearance determines destiny, the ugly one has to look after the house, the handsome one can be taken out, and each can be regarded as performing its own duties. Chen Long felt that he was being discriminated against because of his appearance, so he took another handsome team member out. He asked casually: "Xiaoyu, is there an inn nearby?" It turned out that the ugly one was named Xiaoyun and the handsome one was named Xiaoyu.
Xiaoyu was handsome and smart, and said hurriedly: "There is a hotel with quite good facilities. But when I saw my lord smelling the smell on his clothes just now, I thought he was all rotten and needed to take a bath. Why go to an inn? There is one not far away. Big bathhouse!”
Chen Long was overjoyed when he heard this. Xiaoyu could draw inferences from one instance and put forward better suggestions. He was indeed a talented person who knew how to flatter him. It was worth bringing him out. When the two of them arrived at the bathhouse, they released their restraints three times and jumped into the large pool regardless of others' disdainful looks.
The warm pool water quickly washed away the fatigue of the past few days. Chen Long couldn't help but close his eyes and enjoy it. He apologized to the other special operations brothers in his heart and told Xiao Yu: "Brothers who have returned from changing their posts, please go back and let them take turns to take a bath." !”
The brew was soothing and comfortable. While Chen Long closed his eyes and enjoyed it, the light brain in his brain began to study the classics again. Based on what Zheng Xuan learned, he first studied the "Jingshi Yi", also known as "Jingshi Yi Zhuan". It was written by Jingfang in the Western Han Dynasty and was influenced by Jiao Yanshou, a member of Meng Ximen in the "Yi". Because he specialized in yin and yang catastrophes, it was also called "Disasters". Meng's Jingfang".
Meng Xi's "Yi" study uses sixty-four hexagrams to distribute the climate, and uses the hexagrams to predict good and bad luck. When Jiao Yanshou talked about "Yi", he liked to infer disasters, use natural disasters to explain hexagrams and deduce human affairs. Ban Gu of the Eastern Han Dynasty summarized Jiao Yanshou's academic theory in "Han Shu": "His theory is good at disasters, divided into sixty hexagrams for daily use, with wind, rain, cold and temperature as the weather, and each has its own experience." The study of "Yi" in the Han Dynasty became Jiao Yanshou was the originator of the science of arithmetic.
Jingfang learned "Yi" from Jiao Yanshou and learned the true meaning of Jiao's "Yi" study. He pushed Jiao Yanshou's practice of teaching "Yi" based on disasters to the extreme. He preached it everywhere and used it to interfere in politics. This school of "Yi" learning became famous at that time and had a great influence on later generations. Jiao Yanshou probably saw the danger of Jingfang using "Yi" to interfere in politics, and once said with some worry: "Those who find my way to die will be born in Jing." And the final outcome was just as Jiao expected.
However, there is no causal connection between disasters and politics. If you want to use disasters to intervene in politics, you must have a certain understanding of the political, economic, military, diplomatic and other aspects of the situation at that time, have insight into its development and change trends, and be able to make relatively accurate predictions. Only when these predictions are combined with natural disasters and abnormal celestial phenomena can they be accepted by people. Jingfang has no shortage of capabilities in this area. At that time, "the Western Qiang rebelled, the sun was eclipsing, and it was green for a long time. The light was gone, and the fog was not clear." Jingfang took this opportunity to "count sparsely, and first tell what will happen. It will be a few months in the near future and a year in the future. What he said hit the mark repeatedly. , the emperor said (pleased) it." ("Hanshu Jingfang Biography").
By talking about disasters, Jingfang gained the trust of Emperor Yuan of the Han Dynasty. When Emperor Yuan of the Han Dynasty summoned him, he took the opportunity to preach his political opinions to Emperor Yuan, saying: "In ancient times, emperors used merit to promote virtuous people, and all things were transformed into auspicious things. In the last days, people were selected by reputation and reputation, so their merits were wasted and disasters occurred. It is appropriate. Let all the officials try their best, and the disaster will be averted."
Emperor Yuan of the Han Dynasty was pleased with him and allowed Jingfang to participate in the government affairs and become the center of the court. Unfortunately, due to various reasons, he was ostracized by powerful ministers Zhongshu Ling Shi Xian, Shangshu Ling Wulu Chongzong and others, and was eventually executed by Luo Zhi on shocking charges.
As for the sixty-four hexagrams, it was created by Xibo Hou Jichang (King Wen of Zhou) during the seven years he was imprisoned by King Zhou. He studied Fuxi Bagua in prison and deduced it based on the eight trigrams. Therefore, it is also called the sixty-four hexagrams of Zhouyi.
The sixty-four hexagrams are composed of the upper and lower parts of the two hexagrams. Each hexagram has a special meaning, which is the so-called line image, which is the key content of Jing Fang Yi. Hexagrams such as Eight Palaces (three hundred and eighty-four lines of sixty-four hexagrams), Najia, and An Liuqin are extremely lengthy.
Let's look at "Nine Chapters on Arithmetic", which is the first mathematical treatise in ancient China and the most important one among the "Ten Books on Arithmetic". Zhang Cang and Geng Shouchang of the Western Han Dynasty had made additions and arrangements, and at that time it was basically completed. The final book was written in the early Eastern Han Dynasty at the latest, and most of the circulated versions are the annotated versions of "Nine Chapters" written by Liu Hui in the fourth year of Jingyuan, Emperor Wei Yuan of the Three Kingdoms period.
"Nine Chapters on Arithmetic" is very rich in content. The whole book summarizes the mathematical achievements in the Warring States, Qin and Han Dynasties. At the same time, "Nine Chapters on Arithmetic" also has its own unique achievements in mathematics. It is not only the first to mention the problem of fractions, but also the first to record issues such as surplus and deficiency. The chapter "Equations" also explains negative numbers and their addition and subtraction for the first time in the history of world mathematics. algorithm. It is a comprehensive historical work and the most concise and effective applied mathematics in the world at that time. Its appearance marks the formation of a complete system of ancient Chinese mathematics. Zheng Xuan's research, which combines arithmetic with the Book of Changes, is even more difficult to understand.
In particular, Chapter 9 "Pythagorean" lists various problems that can be solved using the Pythagorean Theorem. Most of the contents were closely related to the social life at that time, and a general solution formula to the Pythagorean problem was proposed. In the West, Pythagoras, Euclid, etc. only obtained several special versions of this formula. In this situation, it was not until Diophantus in the third century that similar results were achieved, which was already about three centuries later than "Nine Chapters on Arithmetic". There is still some content in Pythagorean Chapter, but it is still a modern thing in the West. For example, the set of formulas given in the last question of Pythagorean Chapter were not derived by the American number theorist Dickson until the end of the 19th century abroad.
Chen Long didn't expect that just one book of "Jing's Book of Changes" would involve so many stories, as well as the profound and profound study of "Book of Changes". He couldn't help but think about pulling out the scimitar from the side of the pond and scraping it. Get rid of that ugly beard. When I opened my eyes, I suddenly saw nothing around me. Why was Xiaoyu who was there just now missing?
If you want to know what happens next, listen to the explanation next time.
