Omniscient and Almighty

Chapter 557 Truth and Beauty, Square and Round

Mr. Chen continued to narrate.

"The diameter is fine, why is there a radius? It's because of the wheels, the wheels of the car."

"It is impossible to establish the concept of radius by only looking at the sun and moon, trees, people's eyes, etc."

"Applied to mathematics, this is the case."

"In other words, it can also be said that it is the application that opened up mathematics, and it is also the application that is constantly developing and developing mathematics. Times are endless, applications are endless, and mathematics is endless."

Xu Guangling nodded.

Is there no end to his journey as a great master?

should be.

But there is no need to talk about things that are too far away, and it is meaningless to talk about them.

At present, his body and mind are always locked in the achievement of "knowledge aperture".Not to mention too far away, even the "Heaven and Earth Aperture" after the "Consciousness Aperture", Xu Guangling will not imagine the slightest bit of it for the time being.

If there is no achievement in consciousness, the heaven and earth are like castles in the air.

If you don't accumulate steps, you can't reach a thousand miles.

The ancients used one step as a "step", and each step with the left and right feet as a complete "step". What Xu Guangling wants to do now is to move forward steadily step by step.

Don't be afraid of slowness, as long as you use your body and mind together.

Don't be afraid of slowness, just go all out.

Don't be afraid of slowness, as long as you always walk on this road.

"Some people say that there are only two universal languages ​​in the universe, one is mathematics and the other is art."

"Mathematics is 'truth', art is 'beauty'."

"There is beauty in truth."

"When we look at the starry sky at night, whether it is the brilliant Milky Way, or the spoon and spindle, etc., they are all very beautiful. Heaven and earth may not have art, but it does present beauty in a real way."

"The heaven and the earth are the picture scrolls, and the avenues are the rafters."

"In this museum of heaven and earth, people first feel the beauty of each piece of art, and then look up to the sky and earth to get deeper into its truth little by little."

"There is truth in beauty."

"In terms of our classical poetry, from the four characters of the pre-Qin Shijing, to the five characters of Han Yuefu, then the six characters of the Wei and Jin Dynasties, and then the seven characters of the Tang and Song Dynasties."

"After that, there are no more eight words, until seven."

"And in the five or seven words, there is a verse, flat, flat, flat, flat, flat."

"Rhythmic poetry was not prescribed by anyone, nor was it invented by anyone. People look at the poems that have not been particular about in the past, and find that many poems, especially those of famous and great poets, actually conform to such a law. "

"Different regions, different times, different people, different levels, and in different moods, write different poems. And in these poems, in statistics, we can find such a common law .”

"What is this rule?"

"It's the truth, it's the truth."

"Why stop at seven words, can't eighty or ninety words work?"

"Why is there a lot of complexity in the framework of the flat and the flat?"

"Even until today, in fact, we don't know."

"We only know that this is a kind of 'truth', a kind of truth that has not yet been deciphered."

"But whether we know it or not, whether it is broken or not, it does not prevent us from appreciating and feeling the beauty in it."

"This is the East."

"And in the West, Zhuo Yan, you must also know that very famous number in mathematics, 0.618."

Xu Guangling nodded.

"The golden section runs through both mathematics and art. Whether it is the artistic creation of heaven and earth, or the artistic creation of human beings, there is such a kind of 'truth' and 'beauty' permeating in many places."

"We can make such a presumption that all artistic creations originate from the truth and pursue beauty, and then in the process of pursuing beauty, unconsciously or consciously, they move towards a higher level of truth."

"Every great artist's creation must show beauty in the truth, and the truth must be contained in the beauty."

Xu Guangling was thoughtful.

So in the future, when it comes to reading, at the two ends of a certain balance, he wants to put mathematics on one end, and poetry, music, painting, etc. on the other end?So that it is not ruled out that sometimes, art is studied in a mathematical way, and mathematics is studied in an artistic way.

With a slight thought, Xu Guangling immediately thought of Bach's "Twelve Equal Laws".

"Let's talk about circle."

After a pause, Mr. Chen said slowly.

"The moon is round, the earth is round, the sun is round, and trees are round."

"But we now know that these circles are not perfect circles."

"Why the stars are round, and why they are not perfect circles, these are very complicated, we still can't go deep into its root and essence, but there is one biggest reason why the tree trunks are not perfect circles."

Xu Guangling nodded, and then said: "The sun."

"That's right, the sun." Mr. Chen smiled, "Take the tree as a reference, or from the standpoint of a tree, the sun always travels from east to west, not from south to north."

"So no matter how the seasons change, or how the sun rises or falls, the degree of light received by this tree is always uneven, and then its growth also shows an uneven trend."

"In the natural state, the faster the 'tree' grows and the sparser the texture, the flatter it will be."

"Therefore, in the case of sufficient light, we can judge its texture by the roundness of the tree. Similarly, we can also determine its latitude on the earth by the roundness of the tree."

"Trees at different latitudes in the north and south have different coefficients of one-way expansion or expansion because of the different lighting conditions they receive."

"A single tree may have a large deviation, but if there are many trees together, the latitude can be accurately positioned."

Xu Guangling nodded.

"If a round thing is oppressed or restrained, it will make it less round, or even not round at all."

"The same is true for the moon, the earth, and the sun, so is the case for huge galaxies, and so is the case for something as small as a tree."

"It's the same with people's hearts."

"What is the shape of a person's heart? It is invisible, but if it is described, the heart of a child should be a perfect circle."

"As it grows up, this perfect circle gradually changes. In our language, we use some words to describe people's character, such as gentleness, perseverance, extreme, etc., are actually expressing The difference in roundness."

Xu Guangling was deep in thought.

"Walking on the road, I saw 100 yuan."

"To pick up or not to pick up?"

"Money is a good thing, I want to pick it up. This is the 'original heart'."

"Money is a good thing, but this money is not mine and should not be picked up. This is 'morality'."

"If I don't pick it up, I will be picked up by others, so it's better to make it cheaper for others than for me."

"If I don't pick it up, someone else will pick it up, so I pick it up, wait for the owner, hand it over to the management office, etc., but considering the actual situation,..."

"It's 'reality.'"

"I'm very rich, and I don't care about this at all, so I walked by very indifferently and ignoring it."

"There are many more to list."

"From birth, from childhood to adulthood, people's hearts are faced with similar situations almost every moment, and then sway from side to side, back and forth, and in bits and pieces, they are under the oppression or traction of the outside world."

"Confucius has a saying, 'When I am ten, I am determined to learn; at thirty, I stand up; at forty, I am not confused; at fifty, I know the destiny;

"Do whatever you want without breaking the rules, these are actually two things."

"First do whatever you want."

"Then it's not breaking the rules."

"Do whatever you want, it's inside, let the heart stretch, presenting the most natural state closest to 'circle'."

"Do not transgress the rules, it is outside, follow the customs when you enter the country, and follow the various requirements of the times, society, collective, etc. for people."

"To live a heart as close as possible to a circle requires both self-cultivation and qualifications."

"That's a tall order."

Xu Guangling nodded.

Next, the course continues.

The class lasted about two hours.

From circle to hexagon, the shape of a honeycomb, and the shape of a pile of soap bubbles, and then from hexagon to triangle, and then to a square, Mr. Chen once again demonstrated to Xu Guangling the height and The breadth of learning rich five cars.

After the two-hour class, Mr. Chen also assigned a lot of homework for Xu Guangling just as Xu Guangling assigned homework for the two elderly people during this period. hurt!"

From "Zhou Bi Suan Jing" to "Nine Chapters of Arithmetic", from Pythagoras, to the Fibonacci sequence, from the Pythagorean theorem, to Euler's formula...

There are so many things to look at.

After explaining the system for two hours, Mr. Chen arranged for Xu Guangling, which may take more than two hundred hours, with a lot of content filling in every aspect.

The next day, many mathematics books were sent up the mountain.

As for Xu Guangling's reading content, in addition to the three categories of sage books, Taoist books, and farming books, there is another major category, mathematics.
