Hey, everybody, today we talk about a southern song math master, yang fai. Perhaps you've heard of the yang fai triangle, but yang fai is not just a pronoun for yang fai triangle, but his mathematical achievements are much more than that. Today i'll take you to the full extent of the legends of this mathematician and all the math and black technology you don't know。
Yang fai lived in the southern song era (about the 13th century), when technology was not as advanced as it is today, and mathematics was a “high-end knowledge” for a few. But, unlike yang fai, he does not only understand mathematics, but is also particularly good at making complex mathematical knowledge accessible and easy to learn and apply。
His most well-known work is the elaboration of the nine chapters algorithms, a book that can be described as a “perception” of mathematics, detailing the mathematical methods and techniques that prevailed at the time, in particular the systematization and innovation of the classic mathematical works of the nine chapters. In short, yang fai was the “stealer” and “innovator” of the mathematical knowledge of that era。
When it comes to yang fai, the first thing that comes to mind is the yang fai triangle. It looks like a simple digital triangle, but the mathematical patterns behind it are amazing。
In fact, this triangle was first discovered by the northern song's ja-hyun, but yang fei drew it out in detail and made it clear in his book, and then people named it after him。
What's so powerful about the yang fai triangle
The triangle seems simple, but it took several hundred years for mathematicians to slowly discover its secrets. Yang fai has given it “generalized” to a larger number of people, known as the “net red pattern” in mathematics。
Apart from the yang fai triangle, yang fai has another invention that has to be mentioned — the enzyme。
And as you can see by name, it's a method of calculation related to the accumulation. In short, it is used to calculate the number of objects accumulated, such as bricks, food, etc。
Imagine how to quickly calculate the totals in the face of complex piles without calculators in ancient times? Yang fai's invention is like a mathematical toolbox that helps you solve this problem。
This not only increased the efficiency of the work at the time, but also promoted the application of mathematics in real life. It can be said that accumulation is an example of the combination of ancient mathematics and productive life。
You think yang fai can only make a big deal? Wrong! He's also focused on making it easier。
In those years, both multiplication and division were cumbersome, especially in the face of large numbers, with high computational error rates. Yang fai has improved the traditional multiplication by creating faster and more accurate calculations, later referred to as the “multiplier shortcut”。
How good is that? In short, it is to make it possible for ordinary people to quickly calculate complex multiplier problems, reducing time and error. It can be said that yang fai has made math "ground-to-ground" so that more people can use it and use it。
In conclusion, yang's greatest contribution is not just a formula or a pattern, but his attitude to mathematics。
Together, these three points have created yang fai's place in china's mathematical history。
You might ask, why are you watching yang fai so far from us? In fact, these mathematical giants in history have given us much more inspiration than you think。
Math is not just an abstract symbol, but a tool for life. Yang fai showed us that mathematics helps people solve real problems and promotes social progress. Innovation and inheritance are equally important. The spirit of yang fai, who inherited the achievements of the constitution of ja ' ía, is worthy of learning. Breaking stereotypes, math can be fun. The yang fai triangle is not just a mathematical symbol, it's more like a beautiful digital art painting, and it's interesting to see。
Having said all this, do you have a new understanding of yang fai? He was not just a math genius at that time, he was a pioneer in mathematics. With his wisdom and hard work, he has made complex mathematics simple and practical, affecting generations to come。
So, next time you see the yang fai triangle, don't look at the back formula, think about yang fai, the hard-working and smart south song mathematician behind this
