Chapter 557: Evil Makes Up for Metaphysics

It is said that Chen Long worked hard all night, gave up the tempting idea of tracking Yue Ji deep into the enemy's den, and finally said goodbye to Oh He Yaoge, returned to the greenhouse to rest, and deeply sighed that he came to rescue his beloved wife Diao Chan, but he was stuck in the big quagmire of Xiliang and couldn't extricate himself, and returned to the Central Plains!

When will you raise a gun and leap on a horse and set foot on the Xiliang Gobi?

When Long Chen woke up, he saw that the sky was bright outside the greenhouse, remembered the date with Jiang Wei, and then got up to tidy up his bags, suddenly smelled the sour smell all over his body, and touched the beard on his chin again, knowing that he hadn't taken a good bath for several days. Seeing that there were only two special combat team members guarding the door quietly, knowing that all the team members were carrying out surveillance tasks overnight, he shouted sorry in his heart, and he couldn't care much about it, and said to the uglier one: "You are here to watch the house." ”

Appearance determines fate, the ugly have to take care of the house, and the handsome one is easy to take out, and they can be regarded as performing their duties. Chen Long felt that he was suspected of discrimination in appearance, and went out with another handsome player. He asked casually: "Xiaoyu, is there an inn nearby?" "It turns out that the ugly one is called Xiaoyun, and the handsome one is called Xiaoyu.

Xiaoyu is handsome, and the person is also bright, and he is busy: "There is one, and the facilities are quite good." However, just now, when the subordinates saw the lord smelling the smell on his clothes, he thought that he was all spoiled and wanted to take a bath. Why go to the inn, there is a big bathhouse not far away! ”

Chen Long was overjoyed when he heard this, this Xiaoyu can draw inferences from others and make better suggestions, he is indeed a talent who can make sycophants, and he will bring him out in vain. When the two arrived at the bathhouse, they released their restraints from the shackles of three times and divided by two, and jumped into the big pool regardless of the disdain of others.

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, and said sorry to the other special operations brothers in his heart, and told Xiaoyu in his mouth: "Brother who came back from the changing of the guard, you go back and let them take turns to take a bath!" ”

Soaking comfortably, while Chen Long closed his eyes and enjoyed it, the light brain in his brain began to make up for the scriptures again. According to Zheng Xuan's learning, the first attack on "Jing's Yi", also known as "Jing's Yi Biography", was written by the Western Han Dynasty Jingfang, and was influenced by the "Yi" Mengximen Jiao Yanshou, because of the Yin and Yang catastrophe, so it is also known as "Disaster Meng's Jingfang".

Meng Xi's "Yi" learns to distribute the climate with sixty-four hexagrams, and uses the hexagram to say "Yi", accounting for the good luck and evil. Jiao Yanshou talks about "Yi", likes to push disasters, uses natural disasters to explain hexagrams, and derives personnel. In the Eastern Han Dynasty Bangu's "Book of Han", Jiao Yanshou's scholarship is summarized: "It is said that it is longer than catastrophe, and it is more valuable to divide sixty hexagrams into daily affairs. "In the Han Dynasty, the study of "Yi" became the study of mathematics, and Jiao Yanshou was the initiator.

Jingfang learned "Yi" from Jiao Yanshou, and learned the true meaning of Jiao's "Yi". He pushed Jiao Yanshou's practice of preaching "Yi" to the extreme, preaching everywhere, and interfering in politics with it, making the first-class school of "Yi" study famous at that time and having a great influence on later generations. Jiao Yanshou probably saw the danger of Jingfang's interference in politics with "Yi", and once said without worry: "Those who have my way to die, Jingsheng is also." And the final outcome was as Jiao expected.

However, there is no causal connection between disasters and politics, and if we want to interfere in politics by talking about disasters and differences, we must have a certain understanding of the political, economic, military, and diplomatic patterns at that time, gain insight into the trend of its development and change, and be able to make relatively accurate predictions. There is no shortage of capabilities in Jingfang. At that time, "the West Qiang is reversed, the sun is eclipsed, and it is green for a long time, and the light is dead, and the fog is not fine." "Jingfang took this opportunity," the number is sparse, and the first word is that it will be, in recent months, far from one year old. In what he said, the Son of Heaven said (happy). (Hanshu Jingfang Biography).

By talking about the catastrophic method, 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: "The ancient emperors were virtuous with merit, and all were transformed into successes, and Rui should be written; In the last days, people will be judged by discredit, so the merit will be wasted and cause disasters. It is advisable to let all the officials try their own merits, and disasters can be stopped. ”

Emperor Yuezhi of the Han Yuan Dynasty let Jingfang participate in the government and became the center of the imperial court, but unfortunately for various reasons, he was squeezed out by Shi Xian, Shangshu Ling Wulu Chongzong and others, and was finally executed by Luo Weaving sensational charges.

As for the sixty-four hexagrams, they were created by Xibohou Jichang (King Wen of Zhou) during the seven years of his imprisonment by King Zhou, who devoted himself to studying the Fuxi gossip in prison and deduced on the basis of the eight trigrams, so it is also called the sixty-four hexagrams of Zhou Yi.

The sixty-four hexagrams are composed of two eight trigrams. Each hexagram has a special meaning, that is, the so-called hexagram, is the key content of Jingfangyi, the eight palaces (sixty-four hexagrams and three hundred and eighty-four hexagrams), Najia, An six relatives and other hexagrams, the range is extremely lengthy.

Looking at the "Nine Chapters of Arithmetic", it is the first mathematical treatise in ancient China and the most important one in the "Ten Books of Arithmetic". Zhang Cang and Geng Shouchang of the Western Han Dynasty had made additions and sortings, and at that time they were generally final. In the end, the book was written in the early Eastern Han Dynasty at the latest, and most of the books circulated were annotated by Liu Hui for the "Nine Chapters" in the fourth year of Emperor Jingyuan of Wei during the Three Kingdoms period.

The Nine Chapters of Arithmetic is very rich in content, and the whole book summarizes the mathematical achievements of the Warring States, Qin, and Han dynasties. At the same time, the "Nine Chapters of Arithmetic" also has its unique achievements in mathematics, not only the earliest mention of fractions, but also the first record of surplus and deficit problems, and the "Equations" chapter also expounded negative numbers and their addition and subtraction operations for the first time in the history of world mathematics. It is a comprehensive historical work, the world's most concise and effective applied mathematics at that time, and its emergence marks the formation of a complete system of ancient Chinese mathematics. And Zheng Xuan's research, which combines arithmetic with Zhou Yi, is even more difficult to understand.

In particular, Chapter 9, "Pythagorean", lists various problems that can be solved using the Pythagorean theorem. The vast majority of the contents were closely related to the social life of the time, and the general formula for the Pythagorean number problem was proposed, while in the West, Pythagoras, Euclid, etc., obtained only a few special cases of this formula, and it was not until the third century that Diophantine achieved similar results, which was about three centuries later than the Nine Chapters of Arithmetic. The Pythagorean chapter still has some content, but in the West it is still a modern thing. For example, the set of formulas given in the last question of the Pythagorean chapter was not formulated by the American number theorist Dixon until the end of the nineteenth century abroad.

Chen Long didn't expect that there were so many stories involved behind just one copy of "Jing's Yi", and it also involved the broad and profound "Yi" studies, so he couldn't help but think about pulling out a scimitar from the side of the pool and shaving off the ugly beard. When I opened my eyes, I suddenly saw that there was nothing around me, why did the light rain that was still on the side disappear just now?
