The college entrance examination mathematics is over, and I did not expect that the hot search was actually the topic of exam cheating, which was really unexpected. ▼
In fact, I originally wanted to tell you about this year's college entrance examination math paper, which is quite interesting.
Among the published mathematical questions, there is logical reasoning in the context of volunteer training for the Beijing Winter Olympics. ▼
There are measurement calculations for Mount Everest. ▼
In addition, mathematical analysis and application in the traditional culture of paper-cutting art can also be seen. ▼
There is also a sampling analysis of how to analyze the economic income of rural households in the national poverty alleviation work. ▼
Learning mathematics, in addition to the basic mathematical foundations, knowledge and formulas, you can already see its close application and combination with related elements such as science and technology, social development, etc., and I think this is a signal for us.
Because what we want to see is not this year's college entrance examination questions, but what kind of learning scenarios children will face in 10 years.
If we trace the entire development process of mathematics, we can also feel that it will increasingly encourage children to jump out of the previous formula routine, but guide children to think about the application of mathematics, and return to mathematics as the solution to everything.
This return to the most fundamental origin of mathematics, and the discussion of the original intention, we really go to a tortuous way.
When I was a child, I didn't understand why we had to learn mathematics, but mathematics was a compulsory subject in school, so I memorized one formula after another, and then I used and tried to solve one exercise after another, I learned mathematics in order to make my exams not bad, I knew that I didn't love this subject at all, and I would never see it again after graduation.
It wasn't until I went to the University of Hong Kong and began to really contact various social science topics that I found that one of the core values of mathematics was to solve one social problem after another, we looked for laws in life, and then through operation and reasoning, turned the laws into data precipitation, and finally guided our lives.
One of the research topics that impressed me was how to reduce the suicide rate among Hong Kong's youth, which was to analyze and study the risk index and intervention effects of various regions in Hong Kong through mathematics.
It can be said that if I had not really experienced the application of mathematics in life, I would not have deeply felt that the formulas we had to learn when we were young, the problems to be solved, could still have such a big role in life.
Today's video, a video born in 1959, is only 27 minutes long, and is an animated film with the protagonist being Donald Duck, produced by Disney. ▼
In 1960, he also won the 32nd Academy Awards for introducing every child to the true charm of mathematics in an easy-to-understand way.
My first impression after watching this video was: It's a pity that I didn't have the opportunity to watch this video that year.
If I had seen this video earlier, I might have subverted my impression of mathematics and re-understood the uniqueness of mathematics.
| the beginning of the story |
The protagonist is Donald Duck, a Disney star that everyone is familiar with, and the beginning of the story begins with Donald Duck walking into a mysterious mathematical wonderland. ▼
The landscape of this mathematical wonderland is full of numbers. ▼
This is the fantasy land of mathematics. ▼
| mathematics is the principle | music
In Donald Duck's curious eyes, the guide took Donald Duck to feel the strangeness of a musical string. ▼
Donald Duck can't understand it, what does this string have to do with mathematics? So the guide took him to ancient Greece, the time of Pythagoras. ▼
A man named Pythagoras, while studying a string one day, discovered a wonderful phenomenon, and through the simple relationship of positive ratios, he could find some wonderful laws of sound. ▼
But does finding a law mean discovering mathematics? Wrong, in Pythagoras's time, mathematics was forbidden, and no one was allowed to discuss mathematics, because the social civilization of the time did not allow mathematics to exist. ▼
Donald Duck follows the secret Pythagoreans into their secret base, only to find that they are playing in ensembles. ▼
In those days, there were no instruments or bands, but mathematical researchers created music through mathematical laws, and eventually became the basic principles that influence our music to this day, whether it was staves, scales, pitch and pitch, the principles of mathematics were the standards that underpinned everything. ▼
| mathematics is the foundation | of nature
Not only in music, but also in some interesting commonalities. For example, the pentagram features. ▼
The Golden Ratio rectangle, which the Greeks loved. ▼
The ancient Greeks discovered that by transforming the golden ratio rectangle, an infinite number of identical shapes could be copied. ▼
In this process of reproduction, the circle can also be extended to infinity according to the golden ratio. ▼
So mathematics was also applied to architectural design, and the Parthenon temple was built strictly in the golden ratio rectangle. ▼
The ancient Greeks even designed sculptures strictly according to this proportion. ▼
The architectural structure of Notre Dame cathedral in Paris, France is also the same. ▼
In the well-known Mona Lisa portrait, the use of the golden ratio is even more extreme. ▼
Think that's all there is to mathematics? No, you look at nature. ▼
There are many plants, flowers, and creatures in nature, which are themselves mathematical formulas of very standard and strict proportions. ▼
How they reproduce infinitely, the combined graphics are very artistically attractive and unique, so in painting and artistic design, painters who are familiar with mathematical laws will be more likely to create distinctive works. ▼
Many natural creatures, such as the honeycombs we are familiar with, are extremely rigorous mathematical distributions. ▼
| mathematics is a strategic | of life
Chess is also closely related to mathematics, because all its offensive and defensive strategies are based on mathematics. ▼
Including the hopscotch game we loved to play since childhood. Without telling you the answer, in the video you see why it's a math game. ▼
Even the board game we play, its batting and the prediction of its path, all need the support of mathematical skills. ▼
Do you think you can play billiards by luck? Wrong, behind it is strategic analysis. ▼
See how mathematicians dismantle the laws of billiards. ▼
How to use the algorithm to ensure that your batting strategy is "foolproof"
So, precisely because mathematics is deeply embedded in our lives all the time and in all aspects, it is time to clean up those denigrations, criticisms and insults about mathematics! ▼
Let's look at the circle again. Keep spinning the circle, what do you get? ▼
The circle is the basis of many inventions and provides solutions for many ideas. ▼
All satellite and star orbits can be found by cones. ▼
Because of the slicing of the cone, the mirror of the searchlight can be formed. ▼
Mathematics is a subject that can improve IQ and help the brain develop, and the brain is the origin of all inventions. ▼
It is precisely because mathematics gives everything a path to find, so it opens the door to a lot of scientific exploration, making everything possible. ▼
Today's video resources, private message reply keyword "Donald Duck" can be obtained. Because it is a 1959 film, the pixels are not high, but this does not affect its quality, it can be saved and played at home, only 27 minutes, children can understand.
