Chapter 120: The abacus and abacus formulas are introduced
Scientists were a group of unknown people in those days, but they were doing some amazing work. Pen? Interesting? Pavilion wWw. biquge。 info
Although Liu Hong was a marquis of the city gate of Gucheng before, there were twelve city gates in Luoyang, and to put it bluntly, his position was about the same as that of Zhao Yan, the captain of the city gate. A marquis just uses the city gate as his title, and he can also see the royal family's stinginess and jealousy towards the children surnamed Liu.
A gentleman in his thirties next to him hurriedly supported him.
This is Xu Yue, a disciple of Liu Hong, and a fellow villager of Tai Shici, Donglai.
When he learned about Ziyi's deeds, he and Zhao Yun suddenly had a common topic.
As for Liu Hong, although the old man Cai Yong is the same age as him, he is not a few years older, and the grace of carrying him cannot be erased. In this era, the status of literati was more than one and a half points higher than that of arithmetic.
With this relationship, when Zhao Yun went to speak, he did not hesitate at all, and immediately nodded and agreed to today's meeting.
"Old decay Liu Yuanzhuo, thanks to Brother Zilong's high righteousness, carry forward the arithmetic for me, and we are duty-bound to come over." Although Liu Hong's voice was still a little trembling, his mood calmed down.
It's very embarrassing for him, at such an old age, he still calls Zhao Yun Brother Zilong, but he has no choice but to do so. He recommended Cai Bojiao, a contemporary of Zhao Yun, so the title seems grotesque but very pertinent.
There is no one who doesn't want to be famous, and Liu Hong also thought that he has a great reputation.
Fame is something that cannot be seen or touched, but it has unimaginable benefits, such as the promotion of one's own theory.
However, his surname Liu is restricted to death, and the royal family will definitely not like it. Just like a man named Liu Ye, who disdained his surname and became an important member of Cao Cao's group.
Many times, Zhao Yun also felt helpless, the influence of Taoism and Confucianism in this era was indeed too great.
For example, the spread of Buddhism in China had to rely on the stories of these two schools, otherwise the "Lao Tzu Hua Hu Jing" "written" by himself would not have been accepted by those bald people so quickly.
According to the specific inheritance, this Liu Hong has many old brothers, and the one who can pass on the mantle is Xu Yue, who looks taciturn in front of him, and his apprentice is Kan Ze, a famous minister of Eastern Wu in history.
Later generations said that he was named the crown prince and the prince by Sun Quan, and the capital of the country, because of his diligent study of Confucianism.
However, it is very ridiculous to say that his most famous works are the "Notes on the Dry Elephant Calendar" and "Nine Chapters of Arithmetic" by the master and the ancestor, so does it have a dime to do with Confucianism?
Kan Ze also studied pi very well, and Zu Chongzhi's accurate calculation of pi was borrowed from his results.
Of course, today's encounter between myself and Liu Hong, as well as my respect for Xu Yue, I believe that it will reach the ears of those who have a heart.
As long as Zhao Yun is still alive and his value is increasing day by day, I believe that their master and apprentice will have a different ending from history.
As for that Kan Ze, he didn't know what to do, Zhao Yun thought about whether he would use the Zhao family's network to help the child one day, of course, he was afraid that there was a possibility of pulling out the seedlings to help him.
At this moment, Zhao Yun decided to push Xu Yue out first, and it was enough for him to say so many Liu Hong's words.
I believe that it is his disciples who are lecturing, and Emperor Ling will not blame himself when he knows about it.
If Zhao Yun continues to let Liu Hong behave, only God knows what his homophone Emperor Liu will think.
Anyway, the current Zhao family is still very weak, and the emperor's thigh is still strong, and he can't give it up, and if he is not careful, he will fall into a place of no return.
"Did you see this student?" Zhao Yun waited for Liu Hong's mood to stabilize, and immediately introduced: "This is Mr. Yuan Zhuo's disciple, Xu Yue Xu Gonghe. ”
"Just as on the battlefield, there is no great achievement for those who are good at fighting. In the field of science, if you don't talk about being a teacher today, do you know Brother Yuan Zhuo? No, because they are all quietly doing specific things. ”
"Brother Yuan Zhuo created the Qianxiang calendar according to the number of calculations and awarded it to the Gonghe. This son devoted himself to the study of the calendars such as obscurity, Shuo, strings, hope, and the eclipse of the sun and the moon, and further improved the dry elephant calendar. ”
"The study of the calendar laid a solid foundation for the study of arithmetic in the future." ”
"He collected a large number of mathematical materials since the pre-Qin period, and wrote mathematical works of historical significance such as "Records of Mathematics" and "The Use of Arithmetic Scriptures".
"In the form of questions and answers with Mr. Liu, the "Records of Mathematics" introduces 14 calculation methods: less than 100 words, and the bone is sharpened, and the Siwei is flooded, and it is still Tokyo."
"Thank you Uncle Zilong for the compliment," Xu Yue was very pleased, the master was afraid of becoming famous, and he himself did not care about Liu: "In fact, what his old man said often made Yue Mao stunned. ”
I'm going to be an uncle? Zhao Yun touched his nose a little embarrassed, his master called himself Brother Zilong or an equal, and it was really embarrassing for a person who could call himself uncle at his own age to call himself uncle.
A and B suddenly became Xu Yue's stage, and he himself was not stage frightened. A person who believes in science, in his own field, has no fear at all.
"Originally, Yue was still hesitant before, and the thirteenth algorithm in the "Records of Mathematics" was set as abacus." He said eloquently: "After being mentioned by my uncle, Yue Cai made up his mind, this name is correct, because we have an abacus." ”
He was very respectful and shook Zhao Yun to the end again.
After all, the epoch-making Chinese arithmetic tools such as abacus and abacus would have been delayed for at least 600 years if such a bizarre story had not been passed through.
Zhao Yun smiled and accepted this salute calmly, knowing that this was a mathematical maniac representing the respect of the academic community for himself.
The ancient arithmetic chips are actually small sticks of the same length and thickness, generally 13-14cm in length, 0.2~0.3cm in diameter, mostly made of bamboo, but also made of wood, animal bones, ivory, metal and other materials, about 270 pieces for a bunch, put in a cloth bag, tied around the waist to carry around.
When you need to count and calculate, you can take them out and put them on the table, on the kang, or on the floor.
Don't look at these are inconspicuous little sticks, but they have made great contributions in the history of Chinese mathematics.
And their invention has also gone through a long historical development process.
It is impossible to find out when it first appeared, but by the Spring and Autumn Period and the Warring States period at the latest, the use of calculation chips was already very common.
It can be said that using an abacus instead of an abacus is an epoch-making leap, and Liu Hong and Xu Yue's master and apprentice were dumbfounded when Zhao Yun took out this tool.
They knew that Mr. Bo had a very talented son-in-law, whom they had never met, but they had heard that he was very talented in poetry. Naturally, the outstanding achievements in cloud bodies and stick figures also earned the respect of both men.
Zhao Yun's sincere admiration is the formed abacus and the set of addition, subtraction, multiplication and division operations, which are the so-called abacus formula.
Liu Hong's envy, jealousy and hatred can be imagined, and Xu Yue wants to pull Zhao Yun into the lineup of the arithmetic world, in his opinion, his senior uncle, there is simply no one to come to the arithmetic side.
In the past, I always heard that someone was a genius, but the master and apprentice didn't believe it, after all, scientific things can't be hypocritical.
Now, they are completely convinced. (To be continued.) )
