h2> [A new week is coming.,Make up for the change.,Ask for a recommendation.,Of course,There's a guaranteed monthly pass and a like...... Isn't it too greedy? But it's a thing, just get used to it, and a dragon will get more and more comfortable ^_^ down]

The corridor has become darker, and the style has also changed.

It was originally as monotonous as a hotel room, but at this moment, many patterns and carvings suddenly appeared, the red seemed to be stained with blood, and the purple-black stains lingered on it. On the door of each room, there is even a bright green handwriting. Some are long, some are short, one by one, spreading along both sides of the corridor.

Pitch-black skeletons roamed the corridors, curious and fearful of the handwriting on the door. Not close to the door, watching from a distance.

The closest door to Xiao Ling and Pu Rou reads: "Everything is mathematical, perfect, balanced!" Especially, fire, water, wind, and the number of the heavens that God ......"

Below the words are listed the 100 numbers from 1-1oo, which is vaguely a riddle to choose the corresponding numbers. You can't get in if you guess wrong.

"Five out of a hundred? Rub, it's too much, right? Buying lottery tickets doesn't look like this, right? Park Rou couldn't help complaining.

Looking at the title more closely, I was still confused by the riddle: "Perfect, balanced? Prime number? Prime number? The number of squares? Tsk, is there a relationship between numbers and the four elements? God sorts out the numbers in the sky...... Is it the zodiac sign? ”

As she spoke, the shadows around her suddenly stirred uneasily. The green-glowing skull hole roamed around, and the empty nose hole of "Xiuxiu, Xiuxiu" seemed to be sniffing, but the source of the breath could not be found for a while.

[Your actions reveal your whereabouts, and the Cloak of Night has to expend energy to keep you safe.] Suddenly, the system prompt sounded, and the duration of Pu Rou's night cloak was shortened by more than twenty seconds.

"Rub, still buckle time?" Another three seconds less.

Pu Rou hurriedly covered her mouth.

Xiao Ling originally wanted to explain, but when he saw what happened to Pu Rou, of course he immediately shut up. Observing the reaction of the shadows around him, he thought for a moment, and then took out a mask from the deck and put it on. Of course, I started along the way.

"Of course, the four elements have something to do with numbers. The number of all things is an important philosophical thought of Plato, which had a philosophical influence in ancient Greece. This is clearly talking about Platonic polyhedra. Xiao Ling explained. As soon as the mask was put on, the surrounding shadows immediately stopped the commotion, even if he spoke.

What made them react was not Pu Rou's voice, but Pu Rou's breath when she spoke. "To put it simply...... You have bad breath. ”

"Get out!" Pu Rou was irritable, and while taking out her mask to wear, she gave Xiao Ling a kick. Xiao Ling stumbled into a shadow passing by.

The dark shadow rippled and stopped. The same doubts sniffed and searched up.

Xiao Ling's night cloak time was suddenly shortened by more than forty seconds. Pu Rou was still angry, and the demonstrator waved her fist at Xiao Ling. But in the end...... Still can't help but wonder: "What is Platonic polyhedron?" ”

As if he hadn't heard, Xiao Ling walked along the corridor, avoiding the shadows.

"Okay, okay, can't I admit my mistake to you? I'm sorry! What exactly is a Platonic polyhedron? Pu Rou stomped her feet, helplessly coquettish.

Xiao Ling stopped: "Alas, that's why people should read more." What's the use of just having a beautiful face, the surface is like a boiled egg? Can it be eaten or can it be used? ”

The roots of Pu Rouqi's teeth are itchy, and if you can eat it, you won't eat it, and you won't use it if you can use it. But he also knew that this was Xiao Ling in Naqiao, and the only way to know the answer was ......, "You are right, you are right." He nodded again and again, lowering his eyebrows.

Seeing that her attitude was quite correct, Xiao Ling smiled secretly and said the answer: "Plato's polyhedron is also a tetrahedron, hexahedron, octahedron, twelvehedron and eicohedron. Each face has the same shape, each corner has the same spatial structure, and there are only these five standard regular polyhedra, and nothing else. ”

"You were right when you said that God had sorted out the number twelve in the sky, although you obviously don't know how...... At first, Plato only vaguely said that God used the dodecahedron to organize the constellations of the sky, but later Aristotle made it far-fetched into the fifth element, the ether, that the sky is made of the ether. ”

"The fifth element? Is the fifth element not love, but people? Pu Rou couldn't help but interject. was glared at by Xiao Ling, and stopped talking. Studying knowledge with Hollywood blockbusters is like studying history with romance novels......

"The heat of fire makes people feel sharp and stinging, and the representative image is the tetrahedron; When the water is placed on the hand, it will flow out naturally, which makes people feel very smooth, and the image is a ball-like icosahedron; Earth, unlike other elements, is easy to stack, just like cubes; The representative image of air is the octahedron......"

"Actually, there is something that has been passed down since ancient times, and the one that best reflects the practicality of Plato's polyhedron is the ...... dice," Xiao Ling explained to Pu Rou in detail, and then motioned for Pu Rou to press the answer. The answer, of course, is 4, 6, 8, 12, 2o.

However, Xiao Ling is not so good at being a teacher, so he told Pu Rou all this qiē as he was, but ...... He feared that the trials inside the door would be related to these problems. If Pu Rou doesn't fully understand and can't keep up, she will have to be blind.

But Pu Rou's curiosity didn't end there, and after solving the problem on the door, she rolled her eyes and looked at the puzzle on the door they were walking through—

It was a painting, covered in black, yellow, red, and green...... Almost a qiē color can be imagined, as well as dots, straight lines, arcs...... You can imagine all the strokes, but ...... I can't tell what was drawn.

It's as if the canvas used by the oil painter for decades, constantly impregnated with various fuels, and finally became like this. It is like a satellite image of the city overlooking the sky from the sky, chaotic and chaotic, with disordered streets mixed with disorderly buildings......

The underneath of the painting reads: Abstract Table xiàn Master Jackson? Pollock's masterpiece "No. 31", please choose the image that is closest to the essence of this painting.

Below is a dense list, and at a cursory glance, the number is about the same as the hundred numbers on the other door: patterned wallpaper, the back pattern of playing cards, clouds, comic dot paper, rocks, mountains, coastlines, molecular diffraction patterns, snowflakes, trees......

"Jumping from math to art, the span is really big enough!" Pu Rou couldn't help muttering, pointing to the puzzle on the door, "Don't you boast of reading?" If you have the ability to answer this question, you are great. ”

Looking at Pu Rou, Xiao Ling smiled dumbly: "Do you think this question is an art question?" It's still a math problem. Alas, it's terrible to be uneducated! ”

"Woo woo woo ......" Pu Rou couldn't pounce on Xiao Ling and bite Xiao Ling twice, but he also knew that it was useless. Even if he can bite it, it's useless, he has a magical vice in his hand, and he will definitely use it without hesitation and pull out one of his teeth......

Angry and deeply puzzled: Is this a math problem? Are you kidding? Although I can't understand it, it is precisely because I can't understand it that it shows that this is really an art question, and it is still a very high-end art question.

As if he saw Pu Rou's thoughts, Xiao Ling said: "Do you think that high-end art can't be understood, and high-end mathematics can be understood?" I'll explain it to you a little bit. ”

"You know this...... Oh, Jackson? Pollock. Xiao Ling glanced at the annotation under the portrait, "The reason why his painting is classic, is it classic?" ”

Pu Rou looked at Xiao Ling stunned: "I don't read much, don't lie to me." You just ...... I can't remember this guy's name. You don't even know who this guy is......"

Xiao Ling's face should not be calm as usual: "It doesn't matter if I know this guy's name or not, I just know what this painting is about." ”

"Okay, you say, I'll listen." Pu Rou thought to herself: I'll bear with it first, see what you say. Don't let me find the flaw, otherwise you won't be able to find the southeast and northwest with a slap in the face, oh, and up and down!

Pu Rou's thoughts Xiao Ling didn't know, and he didn't care at all: "The most special thing about this painting is that no matter if you look at it close or far away, it is more or less the same." If you take a random piece of this painting, you can't tell how much of it is occupied, how much it has been enlarged or reduced......"

Listening to Xiao Ling's explanation, Pu Roumei's eyes approached the painting for a while, stayed away for a while, and then took a frame with a finger, looking at it from various angles and in various ways, but ...... It's really like what Xiao Ling said, I can't see any decisive difference, I just feel dazzled.

But after looking at it for a while, she suddenly said: "Cut, isn't this just a mess!" Of course, you can't see anything! ”

"If it's messy, you can't judge the distance of vision and the size ratio from the thickness of the mess?" Xiao Ling choked Pu Rou back with a word.

"So what the hell is going on?" Pu Rou had to humbly ask for advice again.

"It's called fractal math." Xiao Ling didn't continue to embarrass her, and announced the answer, "It refers to the knowledge that if a rough or fragmented pattern is divided into several parts, each part is similar to the shape of the whole shrunken...... If this painting has the essence of the spirit, it is the word fractal. ”

He said that Pu Rou still didn't understand, so he had to explain further: "It's like a tree, you take a picture of the fork of the main trunk of the tree, and then you shine a picture of the next level of fork, and then you take a second level of ...... And so it goes on layer by layer. If you just look at the bifurcated parts, you can't tell which one is the main one and which one is the last branch. With that, Xiao Ling pressed the option of the tree.

"Another example is clouds, if you take a photo of a cloud at random, no one can tell clearly, whether this cloud occupies the entire sky, or only a small lump, or even if you look at one side of the cloud, there is no way to judge its specifications......" Xiao Ling pressed the option of the cloud again.

"Oh, so it seems that the coastline is like that. Take out a single paragraph, and you can't judge its length...... "Pu Rou suddenly said.

Xiao Ling nodded and pressed the option of the coastline as well. r1152
