Chapter 7 True Master
Wang Mang watched Liu Xin looking at the pile of bamboo slips filled with problem solutions with his concentration. Wang Mang couldn't help but sigh in his heart, "Paper is better, the bamboo slips are too bulky! If you can use paper to solve these problems, it will be much easier."
”
Unfortunately, Wang Mang could only think this way. Although there was paper in the Han Dynasty, the quality of the paper was generally not high, and the manufacturing cost was still high.
Such a high and low pull made it impossible for Han paper to be effectively popularized. Therefore, in the Han Dynasty and even after the Three Kingdoms, bamboo slips were still the mainstream writing supplies.
Thinking of this, Wang Mang couldn't help but feel happy, and his thoughts flashed, "Then can I improve papermaking?"
Although Wang Mang doesn't know much about papermaking, he still knows the principles of papermaking. As long as he tries more and has more opportunities for trial and error, are he still afraid of finding a cheap papermaking formula?
After thinking about this, Wang Mang became excited. He finally realized the joy of time-travelers carrying golden fingers. It turned out that when he read time-travel novels and saw the protagonists in them making various tools that transcended the times, Wang Mang couldn't bear it.
Live in excitement and imagine what it would be like if you traveled through time.
Now that the opportunity has finally come, how can Wang Mang not be excited?
While Wang Mang was dreaming about improving papermaking, Yang Xiong, who had been watching the excitement for a long time, also joined in.
He never expected that Wang Mang would have such a great talent. Although he was not proficient in arithmetic, Yang Xiong was still good at basic arithmetic.
Yang Xiong exclaimed: "Jujun is truly a genius!"
Wang Mang smiled modestly and said, "Brother Ziyun is so complimentary, but Mang is just some opportunistic cleverness."
Yang Xiong said: "Don't belittle yourself so much. The talent of the great king is superior to mine, and I am self-aware."
Wang Mang was happy when he heard Yang Xiong's flattery, but his current personality doesn't like being flattered like this.
Wang Mang changed the topic, "What is the art that Brother Ziyun usually studies?"
Yang Xiong sighed and said, "What do you think of my accent?"
Wang Mang was stunned for a moment, and then said: "Brother Ziyun, what does this mean?"
Yang Xiong continued to sigh: "After I arrived in Chang'an, I realized my shortcomings. When I was in Western Shu, I also studied Chang'an elegant dialect with Master Yan, but after I arrived in Chang'an, I realized that there were many fallacies in my elegant dialect. Therefore, I worked hard to correct it.
Yes! Now I am studying the way of dialect, determined to organize the rhyme of the world and set a standard for the people of the world, so that they can quickly become elegant."
After Wang Mang heard Yang Xiong's ambition, he not only took a breath of cold air, isn't this about compiling a big dictionary? This is a great undertaking with immeasurable merit!
But as Wang Mang learned about Yang Xiong's great undertaking, Wang Mang was even more amazed.
Yang Xiong's all-encompassing study of dialects aims to collect all the rhymes of dialects he knows around the world and compile them into books, making it an extremely profound sociolinguistics!
After learning about Yang Xiong's ambitious dialect masterpiece, Wang Mang immediately expressed his intention to work with Yang Xiong to complete this masterpiece that spans the ages!
Linguistics is really important to Wang Mang, especially when transportation information was not developed in ancient times. Mastering more dialect skills is equivalent to an extra understanding of the local area.
With these solid foundations in place, even if the gears of destiny continue to move forward according to their original trajectory, then at least Wang Mang can use his own knowledge to understand more about the specific social conditions in the late Western Han Dynasty, and he will not be fooled by the world.
People were beaten.
Therefore, Wang Mang must participate in Yang Xiong's great knowledge no matter what, and study Yang Xiong's dialect in depth!
Wang Mang paid homage to Yang Xiong and said, "Brother Ziyun's ambition is something that Mang admires greatly! If I don't give up, I am willing to become my teacher and complete the study of dialects for my brother!"
Yang Xiong was stunned. He didn't expect Wang Mang to be so interested in the dialect he studied, and Yang Xiong didn't dare to become Wang Mang's teacher.
Yang Xiong said: "You are serious in your words. My dialect skills are no better than those of a small Taoist. How can I use this knowledge as a teacher? If you are willing to learn this skill, I will teach you."
Wang Mang was overjoyed after hearing what Yang Xiong said and bowed solemnly to Yang Xiong, "Thank you so much, Brother Ziyun! Brother Ziyun will be my dialect teacher from now on!"
Yang Xiong was overjoyed. He supported Wang Mang and laughed. Yang Xiong was naturally happy that his amateur research could be so trusted by others.
As for the dialect teacher Wang Mang said, Yang Xiong would not take it seriously. After all, it is difficult to learn dialects in a refined way. If you use this method to teach and recruit disciples, you will be ridiculed by the world.
Today's world worships Confucianism, and the Five Classics of Confucianism are regarded as the most respected. Other than that, other knowledge is nothing more than trivial Taoism, and it is not enough to enter the palace.
This can be seen from the doctors of the Five Classics appointed by the imperial court. Even if a great talent like Yang Xiong devoted his attention to the study of dialects, he never regarded dialects as a grand avenue.
What Yang Xiong admired was Confucianism, which was respected by Confucius. This can be seen from his famous work "Fayan" in later generations. Yang Xiong's "Fayan" was written with reference to "The Analects of Confucius".
p>
When people of later generations discussed Yang Xiong's knowledge, they mainly focused on Yang Xiong's Fu, "Fa Yan" and "Tai Xuan". His research on "Dialect" was regarded by later generations as just some scraps outside of serious knowledge.
That’s all.
It can be seen that even Yang Xiong, who pioneered the study of dialects, did not pay much attention to the "Dialects" he would write in the future.
But Wang Mang, as a person who has come before, is knowledgeable and knows the value of Yang Xiong's "Dialect". That's why he is so excited to worship Yang Xiong as his teacher and learn Yang Xiong's dialect.
Just when Wang Mang was so surprised that he asked Yang Xiong to be his dialect master, Liu Xin finally read all the bamboo slips written by Wang Mang.
Liu Xin looked at Wang Mang as if he were a freak. He had calculated so many questions accurately.
Especially one of the methods for calculating the area of a circle shocked Liu Xin!
Liu Xin has been studying the calculation of circles. In order to study the area of a circle more accurately, Liu Xin is trying his best to cut circles whenever he has free time, trying to calculate a more accurate pi value.
Through Liu Xin's perseverance in calculations, he has now advanced the pi to 3.1547.
Although this value is slightly different from the 3.1415926 known to later generations, and also differs by a few digits, the fact that he was able to calculate pi so close to the correct answer for later generations in the Han Dynasty shows how terrifying Liu Xin's mathematical talent is!
Liu Xin came over with the bamboo slip with the analysis of the area of a circle and asked: "What does the word 'Wu' mean?"
When Wang Mang heard Liu Xin's question, he turned around and looked at Liu Xin's question, Wu? Isn't it π?
But at this time, Wang Mang can no longer explain π. If he continues to explain, Wang Mang will not be able to make it right.
Wang Mang simply explained according to Liu Xin's "Wu": "The area of a circle is difficult to find, and the pi ratio is difficult to calculate, so I took it upon myself to replace it with 'Wu' and derive the calculation."
Liu Xinshen nodded in agreement and said: "It is indeed difficult to calculate pi. I can teach you a method to cut a circle. If you can use this method to find pi, you will definitely be able to get a more accurate circular area."
Wang Mang bowed to Liu Xin, saying that he understood and thanked Liu Xin for his advice. But in fact, in Wang Mang's heart, he really wanted to tell Liu Xin that pi is an unsolvable calculation and an endless calculation result.
