People often think that celebrities are good at everything, but in fact, there are some celebrities whose ethics and moral character are not as good as those of ordinary people. People are blinded by their so-called achievements. Qin Jiushao during the Southern Song Dynasty was a great mathematician and an official. Mathematical achievements can be said to be universally recognized, and to this day, they are also quite remarkable world achievements! Although this person has extraordinary achievements, but his character is very poor, his heart is very vicious, only if he offends him, he can poison you at any time, he is a grumpy, six relatives do not recognize the Lord, he personally designed the method of getting rid of his son, he also had to get rid of the servants for a little thing, the poet Liu Kezhuang said that he was "violent as a tiger and wolf, as poisonous as a snake and scorpion, non-compound human." What he did hurt heaven and earth, and his heart was like a snake and scorpion, which was not something that humans could do. This person has a good brain, is smart, and loves to learn, but his virtue is too poor.
Maybe it was because of the mathematical tendon that something was wrong with his brain, or maybe he was born a cruel person, a master who regarded human life as a straw. People who are too smart, if they have the stink of despising others, even if they have some kind of achievement, they may be stinked for a long time because of their poor private morality. History will give everyone an impartial evaluation. No one can deceive history, let alone the public.
The public's heart is shining, and the public will say what kind of person you are in the end! Qin Jiushao's private morality is so poor that people disdain to mention it, in order to let the Grand Duke have a clear understanding of celebrities, the author still wants to talk about this cruel lord, a person with a heart like a snake and scorpion!
Qin Jiushao (1208-1268), a famous mathematician of the Southern Song Dynasty, together with Li Ye, Yang Hui, and Zhu Shijie, was known as the four masters of mathematics in the Song and Yuan dynasties.
It was said that he was "extremely skillful, with astrological signs, rhythms, arithmetic, and even construction, all of which are exquisite", and that "games, horses, horses, bows, swords, etc., cannot be known." He successively served as the prefect of Qiongzhou and Si Nongcheng, and was later degraded, died in Meizhou Renshou, and in 1247 completed the book "Nine Chapters of the Book of Numbers", in which the Great Yan Qiu Yi Shu (a solution to the problem of the system of the same remainder equation, which is now called the Chinese residual theorem), the three oblique product method, and the Qin Jiushao algorithm (the numerical method of the positive root of the higher order equation) are important contributions of world significance, expressing an algorithm for solving the numerical solution of the one-yuan high-order polynomial equation - positive and negative opening square.
Qin Jiushao's father, Qin Jiqi, was born as a jinshi, and the official was the upper part of Langzhong and the secretary of the junior superintendent. Qin Jiushao was sensitive and diligent. In the fourth year of Song Shaoding (1231), Qin Jiushao was a jinshi in the examination, and successively served as a county lieutenant, a general judge, a senator, a state keeper, a tongnong, and a temple clerk. He served as an official in Hubei, Anhui, Jiangsu, Zhejiang and other places, and was demoted to Meizhou around 1261, and died shortly after. In addition to government affairs, he immersed himself in mathematics.
He collected extensive data on almanac, mathematics, astrology, music, and construction, and analyzed and studied them. In the fourth to seventh years of Song Chunyou (1244-1247), when he was filial piety for his mother, he edited the mathematical knowledge and research he had accumulated over a long period of time, and wrote the famous masterpiece "Nine Chapters of the Book of Numbers", and created the "Great Yan Qiu Yi Shu". It is known as the "Chinese residual theorem". The "positive and negative prescription technique" he discussed is called the "Qin Jiushao procedure". Almost all mathematical courses in countries around the world, from primary schools, middle schools to universities, are exposed to his theorems, laws, and principles of solving problems.
The American historian of science, Sutton, called Qin Jiushao: "His people, his time, and indeed one of the greatest mathematicians of all his time." This guy is truly amazing and mathematically definitely a one-on-one! Calling him "great" in mathematics is only an academic matter, and it does not mean that he has a "great" character. Knowledge, achievements, sometimes, have nothing to do with human character. However, in dealing with people, we have to pay attention to character. Qin Jiushao, an academic great man, is a dwarf in moral character!
Qin Jiushao's character was also amazingly poor! His behavior was obedient and unexpected, and he was considered by his contemporaries to be "unfilial, unjust, unkind, and incorruptible", and he ran rampant in the township and bullied the side, so he was repeatedly dismissed from his official position or cancelled from his appointment. For example, when his father, who was the magistrate, feasted, he brought prostitutes with him. Another example is that he was able to "seize the land of his superiors" and build his ultra-luxurious manor houses (he personally designed the strange houses). For another example, he ordered his subordinates to kill his son, and personally devised three schemes: poisoning, self-cutting with a sword, and drowning; When he learned that this subordinate had secretly released his son, he actually offered a huge reward and hunted down his son and this subordinate all over the world. One summer, Qin Jiushao and one of his beloved concubines were having fun in the courtyard on the night of the moon, but they were unexpectedly bumped into by a servant who was drawing water, and he thought that the servant was deliberately spying on his privacy, so he falsely accused the servant of stealing, sent him to the official, and demanded that the servant be sentenced to exile. The magistrate believed that the crime of servantdom did not end here, and did not judge him according to Qin Jiushao's request, and Qin Jiushao hated the magistrate for this reason and even tried to poison him to death. Records at that time said that Qin Jiushao "accumulated more poison, and if he did not like it, he would be poisoned by him."
Qin Jiushao's heart is very big, "the tiger poison does not eat children", he does not hesitate to think of ways to get rid of his son for the sake of family affairs, for his own selfish interests, he wants to rob people's land property in crooked doors and ramps, with prostitutes to seek joy, his private life is extremely chaotic, even in ancient times it was breathtaking. This man is a villain of character, an inferior of human beings.
Of course, our mathematical achievements are recognized, recognized, and praised. But we must also recognize the true face of this person, do not learn his character, and do not make such friends. Now advocate both character and learning, if the quality is not passed, you learn no matter how good it is useless. If we do not attach importance to the construction of moral character, the greater the skill, the greater the harm to others. What will society look like in this case? Therefore, it is also necessary to advocate both ability and political integrity, and it is right to put morality in the first place, and it is more important to have virtue than talent, of course, there is virtue and talent, that is the best!
