Chapter 40 The teacher and the apprentice fall out?
If we want to use precise words to describe the large number of dandy boys in Cuiyun, especially Zhang Chen and Lu Sanlang, then the word "complex" can barely describe their mood and feelings.
When they were in the hall of Zhang's house before, even though Tang Ming and Xie Wanquan accused Zhang Shou of cheating the world and stealing his reputation, Zhang Chen and Lu Sanlang felt that Zhang Shou's height, shoulder width, or the tone and intonation of his words were the same as those of the "old man" who had taught them.
"Mr." is completely different.
After that, Ge Yong suddenly appeared again, and the two of them even speculated with surprise and joy whether they had actually become the disciple of this emperor's master, but he was just playing tricks on them, and they had planned such a conversation last night.
But now that we are going full circle, let’s not worry about who the “old gentleman” was last night. Anyway, they were kicked by Ge Yong to Zhang Shou!
At this moment, a large group of people, headed by Zhang Chen and Lu Sanlang, were sitting in the Qingfeng Xulai Hall, looking eagerly at Ge Yong and Zhang Shou, who were sitting across from each other across the small square table, talking about whether they understood or not.
It's like an arithmetic problem in the Heavenly Book.
Ge Yong was talking about the art of cutting circles, hooking three strands, four strings and five; Zhang Shou was talking about infinite series and iterative methods... Until he finally talked about Arabic numerals, after just a few words, Ge Yong suddenly turned livid with anger, Huo Ran
Get up.
"Those ghost-drawing talismans imported from barbarian lands are worthy of being compared with calculations!"
Hearing this, all the dandy boys became energetic.
Could it be that this was just after admitting the closed disciple, and the teacher and student fell out in the blink of an eye?
In this case, they can take grievances and take revenge!
However, something unexpected happened to them. Ge Yong strode forward, grabbed Zhang Shou's sleeves, and dragged him up, then ignored these poor guys at all.
, walked straight out.
Lu Sanlang, who boldly turned his head and looked around, even saw that when Zhu Ying hurriedly chased her, the old man glared at her angrily.
"Old man, I want to discuss arithmetic issues with this kid. Xiao Yingying, don't join in the fun! I discovered as early as when you were seven or eight years old that you have no talent at all in arithmetic!"
Zhang Shou saw Zhu Ying unconvinced and wanted to refute, so he smiled and said: "It's okay, it's just a small problem about numbers."
To be honest, he who had always stayed in the countryside discovered that Arabic numerals, which had only become popular in China very late in history, had entered all walks of life under the vigorous promotion of the imperial court in the early years of this dynasty. At that time, he
I felt surprised and happy at the same time.
Perhaps the calculation and counting methods in ancient China were very advanced, but the Arabic numerals from India can take over the world, defeating even the Latin numerals that once dominated Europe, and finally developed into the most important part of basic mathematics. That is absolutely
It’s not a coincidence!
But even when Arabic numerals were gradually popularized throughout the Ming Dynasty, some people still insisted on using arithmetic symbols as a means of calculation. For example, the old man Ge in front of him was a die-hard supporter of arithmetic. He really didn't expect it.
So, when Xu Laitang came out of Qingfeng, he who was originally dragged by Ge Yong winked at Qi Liang who was following him, and asked someone to help Zhu Ying watch the scene, and then he turned around and dragged the old man away.
Shuibo was not in the mood. He didn't say anything. He took the pen and paper directly from the bookshelf, spread it out in front of Ge Yong, dipped the pen in ink, and wrote a number casually.
This is not a difficult question or a formula theorem, but... a vertical square root. Although for future generations, it would only take a few seconds to input a scientific calculator to open a radical, no matter how troublesome it is...
But at this moment, he listed a long list of square root calculation formulas for Ge Yong in vertical form. This was because he was extremely fast in mental arithmetic, and it only took him a few minutes to calculate the decimal number representing the square root of ten.
.
Immediately afterwards, he used a faster iteration method.
When he finally placed two identical numbers in front of Ge Yong, the old man's face looked as if it was covered with frost.
"Although the former calculation is paper-consuming, it has an advantage. It is not like calculating with chips. If you mess up, you have to recalculate. It requires countless calculation chips, and it is easier to check than abacus. As long as you master the rules, tediousness will become tedious.
Progress step by step in the end. The latter calculation is relatively convenient, but it takes a little effort when trying to root, but it is fast in the end. It is simple and easy to understand using numbers like this from overseas."
He knew that Ge Yong might not be able to overcome that hurdle in his heart, just like people who believe that traditional Chinese characters are the best in the world often paint simplified Chinese characters completely, not to mention that Arabic numerals are a completely foreign culture.
"Sir, when Zu Wenyuan made the Daming Calendar, opponents clamored that the calendar was made by the ancients and would never be easy to change. But what did Zu Wenyuan say? You shouldn't trust the past and doubt the present. If the things from ancient times are wrong,
Now if we still use it according to the rules, then won’t we make mistakes again and again? Arithmetic, like the calendar, must keep pace with the times.”
As Zhang Shou said, he got up and fetched a relatively warm teapot from the cattail bag, washed the teacup, poured it for Ge Yong himself, and then smiled more sincerely.
"I was also a little interested in arithmetic because I read a few books left by my husband. A passing salesman happened to bring a few old books from the market. I saw those numbers from overseas that were simpler than arithmetic.
I became more interested, and you have also seen that Qi Liang’s exercise book is all composed of questions using these numbers. If you think this is deviant, then I admit my mistake. "
Fortunately, when he was renovating the Qingfeng Xulai Hall, he personally sorted and moved out the contents. No one knew that the old man’s arithmetic books were only scraps of paper, otherwise he wouldn’t know how to end it!
"Admit your mistake, but don't regret it. Is this your attitude?" Ge Yong stared at Zhang Shou. When he saw him nodding calmly, he remained silent for a long time with a cold face, and finally smiled.
"If you were so stubborn when I was living in seclusion here, I would have scolded you and walked away. But how could you master arithmetic to this extent in such a short period of time?
How about teaching Deng Xiaodai and Qi Liang, two talented and diligent students?"
He said with some loss of interest: "I also know that over the years I have insisted on using arithmetic chips to count. It is said that I am following the ancient system, but in fact I am following the old tradition. Even the few old friends who are proficient in arithmetic have begun to
I used the numbers that came from overseas... Well, it’s just that because of the face of an old man of my age, everyone didn’t say it to my face..."
"You're the only one who doesn't know how to respect teachers!"
When he said this, Ge Yong blew his beard and glared again. When he saw Zhang Shou smiling and apologizing repeatedly, he said seriously: "Your father-in-law invited me here, of course, not to teach you arithmetic. The books I specially left include
I am just angry at you for calculating the ten classics. But I heard from Xiaodai that you also have some knowledge in classics and history, and have a photographic memory of reading. Don’t waste such good qualifications on trivial matters in the future!"
For fear of Zhang Shou being pretentious, he added emphatically: "If you are greedy for food, just instruct others to do it. The effort of cooking yourself is enough for you to ponder many questions! If you can compare Zu Wenyuan's diameter and circle
If I push it one step further, then I will have no regrets in this life. Alas, I haven't pushed it one step further in a thousand years, and even his "Shu Shu" has been lost!"
Zhang Shou quickly lowered his head, as if nodding respectfully in agreement, not wanting Ge Yong to notice the change in expression on his face.
The subject of mathematics is vast and profound. Compared with those conjectures that no one has been able to solve for so many years, pi in modern times is just a problem that can be calculated to millions of digits with just a super computer...
But to tell the truth, not to mention that the old man didn't believe it, even if he did, he would definitely vomit blood. He should go back and find some excuse for him to find some lost arithmetic classics such as Zhushu, and throw out a few textbooks to give Ge Yong something to study.
Well, maybe it can also give people a second spring?
The next moment, Ge Yong, who just now seemed like a tireless mathematical researcher, suddenly changed his tone.
"Of course those two boys, Tang Ming and Xie Wanquan, were instigated by others. Although I have retired from retirement a long time ago, my status is involved and I cannot stay here for a long time, so I can only protect you for a while. What will happen in the future?
It's up to you and Xiao Yingying to figure it out. Don't blame your father-in-law for leaving you mother and son in the countryside. You will know some things later."
"Treat Xiao Yingying well. Although she is spoiled by her father, she has a good nature. It is rare for her to see eye to eye with you, and her grandmother is behind her to support her. Don't let her down! Come with me back to Qingfeng Xu Laitang.
, I will teach those boys a lesson, this patriarch cannot be in vain!"
