Zu Chongzhi studied natural science throughout his life, and his main contributions were in mathematics, astronomy, calendar and mechanical manufacturing.
Before the Han Dynasty, China generally used three as the value of pi, that is, "three diameters are one". This caused a large error when calculating the circumference and area of a circle.
Based on the scientific method of calculating pi using "circle cutting" created by Liu Hui, Zu Chongzhi used the open secret method and after repeated calculations, he calculated the pi between 3,1415927 and 3,1415926. This was the most accurate in the world at that time.
Numerical value, he also became the first person in the world to calculate the accurate value of pi to the 7th decimal place. It was not until more than a thousand years later that this record was broken by Europeans.
It can be said that pi is Zu Chongzhi's masterpiece. This alone has pushed Zu Chongzhi to the pinnacle of ancient mathematics. Regardless of ancient and modern times, no one can question his historical status in the field of mathematics.
But now, this Wang Xiaotong actually dares to attack the "Master Zu"?
Of course, this is the first time Fang Junshang has heard about the book "Zhushu". He has no idea what the arguments in the book are. Zu Chongzhi and his son are both among the greatest mathematicians in history. There is no doubt that this cannot be said.
It means that all the mathematical arguments are correct. However, according to the scientific spirit of Zu and his son who are neither superstitious about the ancients, dare to innovate, are modest and prudent, have an open mind, and place their hopes on future scholars, Fang Jun will definitely not believe what Wang Xiaotong said.
Comment.
Achievement and character are not the same thing, but sometimes they are closely related.
Just by what Wang Xiaotong said just now, "Invite people who can calculate and discuss the pros and cons. If anyone can send me a word, I will thank you with a thousand pieces of gold." You can know his attitude towards science. He thinks that his work has been completed.
It is so perfect and seamless that contemporaries cannot sing with it...
His complacent and arrogant attitude is not the mentality that a scholar should have.
If such an extremely arrogant mentality can really produce any academic research that will shock the past and the present, then it is a fool!
Kong Yingda solemnly said: "Xiaotong is arrogant and arrogant, but he doesn't know that there is no end to learning? The way to study requires a deep heart, humility and prudence, in order to make progress. If you are impetuous, you will not be able to listen to other people's words, and you will not be able to read other people's books.
, is tantamount to being complacent and not the attitude of learning!"
These words were merciless, pointing out that Wang Xiaotong had an impetuous mind, which was not the mentality that a student should have.
What surprised Fang Jun was that Wang Xiaotong was neither angry nor accepting of Kong Yingda's words. He just thought Kong Yingda was farting. One was rigorous and old-fashioned, while the other was arrogant and talented. They had completely different styles. It was hard to believe how the friendship between the two was maintained...
Wang Xiaotong ignored Kong Yingda's dissuasion, just stared at Fang Jun, and said proudly: "Compared with the "Zhu Shu" written by Zu and his son, which is full of errors and omissions, the "Ji Gu Suan Jing" compiled by a certain person explores the secrets, and it is full of twists and turns.
A good friend will eventually become a couple. A certain person thinks about it every day and night, sighs loudly when writing a book, and often stagnates with this reason, fearing that once he closes his eyes, no one will know about his descendants."
Fang Jun laughed.
It is the responsibility of scholars to contribute their knowledge to society. However, if you think that only you can reach the highest peak, it will be impossible for later people to reach it, let alone surpass your own level.
The mental state formed a sharp contrast, which in vain exposed his arrogant mentality, just like a clown...
Belittle your predecessors, look down upon your peers, despise those who follow you, and think that you are unprecedented and unmatched. Can this be the attitude of a scientist?
A scientist does not have to be a humble gentleman, but he cannot be so arrogant. Under the control of this kind of mentality, it is not impossible to make some creative achievements. However, generally speaking, it is impossible to make achievements of the same level as Zu Chongzhi. This kind of arrogance
With his mentality, Wang Xiao instead of humbly learning and studying things he didn't understand, he dismissed them as "completely wrong and incomprehensible."
Wang Xiaotong was displeased: "Why are you laughing?"
Fang Jun held back his laughter: "This junior has been of great benefit today, so I am very happy."
Whose achievements will shock the past and be remembered forever? No one is more qualified to judge than Fang Jun. Who will be wiped out in the tide of history, and who will be respected by thousands of people after thousands of years? Who can be more qualified than Fang Jun?
Are you sure? In terms of fame alone, Wang Xiaotong's mathematical achievements and theoretical level are far behind Zu Chongzhi's. That "Ji Gu Suan Jing" has never been a shocking literary masterpiece...
As for you, it's probably just a joke.
Wang Xiaotong stroked his beard happily and glanced at Kong Yingda with satisfaction. How about this, the best guy in Chang'an City, wasn't he impressed by someone and willing to be defeated?
Kong Yingda smiled bitterly and shook his head.
If Wang Xiaotong had not been my neighbor since childhood, and he saved me from falling into the water once when I was a child. With the grace of saving my life, how could I have been friends with him for decades based on his academic attitude?
The difference in how we treat people is really huge.
The duty of the Ministry of Rites is not a solemn and rigorous place, it is just a place where officials are on duty. There are neither documents nor strict rules. Although Kong Yingda's reputation spread throughout the Tang Dynasty, he was always kind and gentle to others. Those subordinates and colleagues
When I have nothing to do, I will ask him for advice.
At this time, the Ministry of Etiquette had nothing important to do. When the idle officials heard the loud debate from the room attendant, they couldn't help but sneak over to listen.
Fang Jun felt very good about the academic openness of the Tang Dynasty. There were often discussions among famous Confucian scholars, and everyone could listen. They could gain something, and even express their own opinions. There was no bad habit of being self-conscious.
At this time, officials from the Ministry of Rites quietly came in in twos and threes and sat quietly outside.
Kong Yingda ignored this, while Wang Xiaotong was even more energetic. The more people there are, the more he can spread his reputation...
Fang Jun had no favorable impression of Wang Xiaotong at all. Seeing the old guy's complacency, he moved in his heart and said with a smile: "Senior's cultivation of arithmetic is really a role model for us juniors. I am honored to have a chat with my senior today."
, it’s really a great benefit. But a few days ago, the junior encountered a difficult problem and couldn’t figure it out. I wonder if I can ask the senior for help to solve the problem?”
Do you have any questions?
Wang Xiaotong feels as happy as if he drank ice water in the dog days of summer, that's it! If you have any questions that you can't answer, please ask me, and then I'll answer them for you, which can not only overwhelm you, but also help me to advance, the knowledgeable person.
Spreading your reputation is really killing two birds with one stone!
"Here you go." Wang Xiaotong is extremely confident about his ability in arithmetic. There has never been a difficult problem in the past and present that he cannot solve in his eyes...
Fang Jun said: "Please listen to the question..." As soon as the words came out, he suddenly realized that he had spoken smoothly, and quickly said awkwardly: "Suppose the senior has a boat, and there are seventy-five cows, thirty-four sheep, and two
Fifteen horses, may I ask how old the captain is?"
Wang Xiaotong was stunned.
Kong Yingda was stunned.
The etiquette officials present were stunned...
Everyone started doing mental calculations.
Seventy-five cows, thirty-four sheep, twenty-five horses... There is no choice. As one of the six arts of a gentleman, mathematics must be learned by every scholar. In addition, at this time, there has not yet been the formation of "only" mathematics such as the Song, Yuan, Ming and Qing Dynasties.
In the imperial examination style of "Confucian Classics and History", except for the Four Books and Five Classics, all students are miscellaneous. Every student has done some research on arithmetic and has a very good foundation in arithmetic.
This is this question, but it makes everyone confused...
Wang Xiaotong glanced at Fang Jun in surprise and cursed in his heart: This is not asking for advice, it is clearly to give me a problem and to embarrass me! You little bastard, you are not kind!
But this question...
There was even an official from the Ministry of Rites who came to Kong Yingda's desk. He picked up a pen and paper and wrote the three numbers seventy-five, thirty-four, and twenty-five on the paper, and then marked them as cow, sheep, horse, and Ningmei respectively.
Think deeply, think hard.
Wang Xiaotong looked up at the sky, his eyes slightly closed, but his mind was racing with thoughts.
This question is very strange. It seems simple, but there is a twist hidden in it. Otherwise, the seventy-five cows, thirty-four sheep, and twenty-five horses that seem completely unrelated...how can they be related to the captain?
Fang Jun lifted the kettle on the charcoal stove like an old man, poured boiling water into the teapot, and made himself a cup of fragrant tea. He held the teacup, but did not dare to drink it. His stomach was almost bursting with laughter, and his hands kept
I'm shaking, afraid of burning myself.
Let you Tang Dynasty people experience the power of brain teasers...
