"Constant mathematics, variable mathematics, probability mathematics, and fuzzy mathematics, these four kinds of mathematics also correspond to four different types of civilization. The development of civilization calls for the emergence of corresponding mathematics, and the development of mathematics reflects
Times, sometimes, also inspire times.”
"Constant mathematics corresponds to classical civilization."
"Classical civilization can also be said to be primitive civilization, a civilization of fire, a civilization of human and animal power."
"Xiao Xu, you young people like to listen to music. I remember there is a song called "Once Upon a Time Slowly"?"
"In the past, the sun became slower, and the cars, horses, and mail were all slower. There was only enough time to love one person in a lifetime." Xu Guangling read one of the lines, and then said: "This is actually a poem, which was composed to music, but
I only paid attention to lyrics because of the songs. Mr. Chen, do you also know this?"
I didn't realize that Mr. Chen likes to listen to music before.
If he likes it, Xu Guangling can immediately get a sound amplifier system on the mountain, and then the big speakers can play loud sounds.
However, the audio system has not been completed, and a music room including a recording room is being built.
After all, music is half of Xu Guangling's profession. Of course, it is a bit false to say this now. As the journey of becoming a great master progresses, with the contact, study, and project establishment of medicine, martial arts, food, and now mathematics, etc.
,Research, the original music plays an increasingly smaller role in consciousness.
Xu Guangling didn't know whether he would forget it one day.
But probably not.
For him, music is firstly a memory and secondly a pastime. This will probably be something that will accompany him throughout his life.
No matter how far he goes, there will always be times when he doesn't think about anything or does nothing. He just sits down and quietly plays the song "Lotus" or "There's No Wind and Rain".
For Xu Guangling, as Mr. Chen said before, this is the origin of his coordinates, at least, one of the components of the origin.
From a song, he remembered the person who taught him to sing, and then from that person to those two people.
Xu Guangling's thoughts were floating slightly, just like the white clouds in the distant sky outside the tent that seemed still and yet fluttering.
The sun hangs high in the sky. Under the blue sky, the white clouds look like scattered quilts spread out to dry in the sun. They look like big marshmallows. They also look like the dreams of childhood and youth.
After waking up from the dream, I am no longer a teenager.
No sadness, no joy, just a few thoughts.
Xu Guangling suddenly wanted to drink tea, or he just wanted to hold a teacup in his hand and turn it slowly.
"When I came to see Mr. Zhang two years ago, I heard it at the train station." Mr. Chen's fingers flicked the leaves behind the orange handle.
A large generation.
Once you hear it, you will definitely remember it.
Xu Guangling nodded.
"In the past, life was slow, and everything was slow." Mr. Chen said lightly, "Slowness and simplicity are also the main characteristics of classical civilization."
"Most people work at sunrise and rest at sunset. They can play the piccolo on the back of an ox, they can go hoeing the fields with a load of food, they can play chess pieces and put down the lanterns, or they can come in late and it's snowing, so can they have a drink?"
"In such an era, mathematics is also in its inception, embryonic and early development state."
"The times do not require advanced mathematics."
“Even if someone conducts advanced mathematical research, or a genius accidentally breaks through the barriers of civilization and touches variable mathematics or even fuzzy mathematics, the results will only end up in the study, be shelved, and then be lost.
, and then forgotten.”
"Or maybe thousands of years later, it will be discovered by later generations, causing a burst of wonder. But that's all."
"Why?"
"Because the times don't need it."
"Feet of size 30 do not need shoes of size 40, and feet of size 40 do not need shoes of size 50."
"No matter how good or beautiful the shoe is, if it doesn't fit, it just doesn't fit. It doesn't need it, it just doesn't need it. No matter how exquisite or beautiful it is, it can only be put in a shoe box and put in a corner for a long time.
Dust accumulation.”
Xu Guangling nodded.
The bulk is the bulk.
Even if Mr. Chen is only a master in martial arts, a "martial artist", and not a master in other aspects, it does not prevent him from standing at the height of a master, and then observing and even overlooking other systems from the perspective of a master.
.
At this time, Wu Zong mastered mathematics.
And the reason why he is not a great master in mathematics probably has one and only one reason. That is, "My life has a limit, but my knowledge has no limit." Most of his energy in his life has been devoted to martial arts.
.
Being unknown in other aspects was exchanged for reaching the pinnacle of martial arts.
The gains and losses involved are needless to say.
Martial arts is the foundation of this person. Others, those hundred and ten doctorate degrees, represent the scenery.
Studying with such a teacher, if you want to enter the major of mathematics just based on this, it will not work. You also need to learn from other aspects.
But if it's just for getting started, that's enough.
This will also be the best and highest-level entry-level teacher in the world. Even if I search all over the world, I don’t think I can find ten of them.
Xu Guangling decided to add two more chicken drumsticks to the old man’s dinner today.
Well, we don’t have chicken legs yet, so let’s have two sweet and sour fish!
"Classical, in that era, where did mathematics sprout and people's understanding of mathematics begin?"
"Start from ○."
Mr. Chen circled a "○" shape with his thumb and index finger, "This is zero, it is also a circle, and it is the initial starting point."
"When a child is just born, he opens his clear eyes and looks at his parents. The dark eyes in each other's eyes are all round."
"When you go to work in the fields, you step on the footsteps of the sun and the moon. When you go out with the sun and step on the moon when you return, the sun and the moon are also round."
"In front of and behind the house, the trees are round."
"The chicken crows on the top of the mulberry tree. The chickens (eggs) laid by the chickens that use the trees as their nests are also round."
"When the crops in the fields are harvested, they have to be brought back with a cart. The wheels of the cart are also round."
"From circles to oblate circles, then to irregular circles, and then through comparison, we also have the concepts of 'perfect circle' and 'ellipse'."
"A wheel requires a perfect circle, the more straight the better."
"The wheel is composed of a circle on the outside and a wooden bar in the middle as a support. The circle must be round and the bars must be straight. The rounder the better, and the straighter the better."
"Then, 'rules' and 'rectangles' appeared. To form a perfect circle, to make a square. Without rules, there is no square. To this day, when children learn mathematics, compasses and rulers are still necessary tools."
"Then the concepts of radius and diameter, as well as the concept of a circle, appeared as a matter of course."
"Then, 'π' appeared."
"Three points one four one five nine two six, five three five, *** seven nine three, two three eight four six." At this point, Mr. Chen smiled, "Back then, after I first opened my head, I wanted to test
Memory, I once specifically found pi to memorize."
"However, due to limited conditions at that time, I could only find five hundred digits after the decimal point, which was not interesting, so later, I still took all Tang poetry and memorized it."
Xu Guangling nodded, "Mr. Chen, when it comes to formal non-learning memory, I actually started with all Tang poems."
Saying this, Xu Guangling turned to Mr. Zhang, who was sitting on one side, and said, "Teacher, where are you? By the way, I can guess it without you having to tell me that it is related to medicine, 'Four Gentlemen Soup and Harmony'.
Shenshu, Poria, Licorice is better than this, right?"
Mr. Zhang nodded with a smile, but then said: "I'm sorry, you are only half right. Little things like the Tangtou Song Jue, I have already memorized them when I was a teacher, and I will never forget them. But after I regain my consciousness, I can't forget them."
The teacher has indeed reviewed these things comprehensively and systematically."
"After reviewing it, the first book I really memorized as a teacher was the Nei Jing."
