Mozi said: Shadow is composed of two lights and one light. One light is a shadow. When the light reaches the shadow, the shadow dies.
Countless lights propagate along straight lines, and when the light is blocked, shadows appear.
Most objects in the world do not emit light themselves. The reason why they can be seen by the human eye is because the objects continue to reflect sunlight and enter the human eye.
The formation of a shadow does not change the object itself, but only weakens the light reflected into the human eye, thus creating a "dark" visual effect.
What the human eye sees is determined by the light entering the eye. And everything does not emit light, they only reflect sunlight.
Since this world that looks colorful to humans is only due to reflected sunlight, then colorless sunlight is the most complex light that contains everything.
This is a positive inference.
To prove this inference, we must prove in turn that colorless sunlight can be "disassembled" into countless different lights.
How to dismantle sunlight is the problem that Ding Xiaobo poses to Gongsun Linglong.
The moonlight was thin, and the waves in the pond were looming. The bamboo poles stood straight in the water, so dim and faint that it was hard to tell which ones were reflections.
Gongsun Linglong stood at the edge of the pavilion with her arms folded, her eyes fixed on the green ink bamboo, her fine eyebrows furrowed, her lips slightly turned to one side, and she did not move for a long time.
Ding Xiaobo clapped his hands with a smile on his face and placed an incense burner on the desk. Inside, a stick of incense was floating with green smoke.
He flicked his sleeves, picked up a roast chicken thigh, and while eating, he watched Gongsun Linglong thinking hard. Her eyes were dark, but very bright.
Time passed by, and Gongsun Linglong stood motionless by the pavilion at first, then walked around the pavilion in circles, and then even turned over and jumped on the top of the pavilion.
The crescent moon hid and reappeared several times, and its brilliance fell on Gongsun Linglong's face. The woman's face was white and rosy, and the redness became even whiter, and the fluorescence shone.
"Mr. Gongsun, the last incense stick."
Ding Xiaobo also jumped up to the top of the pavilion, holding the incense burner in one hand, and tilted his head and smiled at Gongsun Linglong.
Gongsun Linglong glanced at him, took a deep breath and said, "How can we know the outcome until the last moment?"
After that, she continued to observe the bamboo poles in the water, her thin eyebrows deeply furrowed, and the moonlight cast uneven light and shadow between her eyebrows.
"Okay, I'm just waiting to hear how the gentleman will answer."
Ding Xiao's face turned pale, one eyebrow twitched, and he half-lyed down on the top of the pavilion, waiting for the last stick of incense.
Thump~
There was a sudden sound on the water surface, and the ripples spread slowly.
Gongsun Linglong's attention was attracted by the movement, and she immediately looked around, only to see the moonlight reflecting off the pool water, and the green bamboo shadows twisting and swaying.
"This is……"
She seemed to have something in her heart, half-leaning her body and staring closely at the water.
"I understand, I understand! That's it, hahaha~"
Gongsun Linglong threw up her sleeves excitedly, raised her hands and shouted, laughing loudly without any scruples.
"Hahaha, brother Xiaobo, you will definitely lose."
She turned around in high spirits and pointed at Ding Xiaobo, which seemed a bit arrogant.
However, great joy brings sorrow. On the top of the pavilion, Gongsun Linglong accidentally stepped on the ground and fell from the pavilion.
"Ah~"
"Mr. Gongsun?!"
Ding Xiaobo exclaimed, slapping his palm down, and his body flew out, obviously trying to catch him immediately.
Gongsun Linglong stumbled and fell, but he was still a famous person, and although his martial arts skills were not very good, he could still save himself in this situation.
When she fell, she grabbed a corner of the pavilion with one hand, turned around with her inner strength, turned over, and was about to fall back to where she was.
"Ah~"
"Ah~"
As a result, one rescued others and the other rescued himself. The two of them collided and panicked for a moment. They fell into the pond at the same time and the water splashed high.
"Pah, pah, mr. Gongsun, are you okay?"
Ding Xiaobo popped his head out, spit out a mouthful of green apple, wiped his eyes with his hands, and looked for Gongsun Linglong eagerly.
"It's an unreasonable disaster. You really caused me a lot of harm."
Gongsun Linglong covered it with her sleeves, spit out the water in her mouth first, and then stared at him very unhappily, "Eat my food, drink my food, and give me problems, and even make me suffer. Xiaobo
Brother, no one in the world can bear a visit like yours."
"Sorry sorry."
"snort."
Gongsun Linglong pursed her lips, jumped onto the shore, and then walked straight towards the house.
moment……
Ding Xiaobo was pouring the water from his boots onto the ground when a package suddenly flew out from behind.
He opened it and saw inside it a Central Academy uniform.
"Hey, Ding Xiaobo, you Xiaobo, you are really embarrassed this time."
He smacked his lips, rolled his eyes a few times, found a slightly hidden corner, put on new clothes, and with the surging internal energy, the embarrassment of falling into the water disappeared in the blink of an eye.
Not long after, Gongsun Linglong also changed her clothes and wore a light-colored long skirt. Except for her disheveled hair, there was nothing rude about her.
She grabbed her hair with both hands, tilted her head and tied it into a braid hastily. As she walked, she said: "With such a delay, the last stick of incense will soon burn out. Brother Xiaobo, let's continue. Please take a seat. Linglong will definitely give in."
You are convinced that you have lost."
Phew~
With his light skills up and his long skirt flowing, Gongsun Linglong fell into the pavilion and invited Ding Xiaobo with his hand.
"Okay, I'm all ears."
Ding Xiaobo responded loudly, kicked off his feet and flew into the pavilion, sitting opposite Gongsun Linglong, "Sir, please give me a try."
Gongsun Linglong smiled slightly, picked up a pot of wine and poured a full cup, then grabbed a chopstick and threw it into the cup.
"This is probably why Brother Xiaobo reminded me of the bamboo pole."
Facing the woman's half-smiling eyes, Ding Xiaobo stretched out his hand to scratch his remaining wet bangs, nodded and said, "Yes, sir, please continue."
"What the eyes see is because light enters the eyes from objects. If the light is weak, it will be dark, and if there is no light, it will not be seen. However, if the bamboo pole enters the water and is broken by visual inspection, it will actually be fine when it comes out of the water. Why?"
Gongsun Linglong also sat down and looked directly at Ding Xiaobo, "This phenomenon is the key. Brother Xiaobo, why don't you and I say this word together to see if Linglong is right?"
This chapter is not over yet, please click on the next page to continue reading! Looking at each other, Ding Xiaobo blinked, "Okay, then it depends on whether you and I can speak in unison."
one!
two!
Gongsun Linglong: "Refraction of light."
Ding Xiaobo: "Refraction."
"Haha, brother Xiaobo, it seems that I won again this time."
"Mr. Gongsun, I admire you very much. I thought about it for several days at home, and then I finally got the idea. You made me completely defeated in just one hour."
"Hey, this is a fallacy."
Gongsun Linglong shook his head repeatedly. It was true that he won the bet this time, but it did not mean that he was smarter than the other party.
She pursed her slightly raised red lips and said seriously: "Brother Xiaobo, it was you who first discovered the extraordinary mystery from this ordinary phenomenon. It was only because I got your direction that I was able to use it in just one hour.
Got this discovery.
In ancient times, human beings drank blood from their hair and did not understand the magical uses of fire. Now that all of us know how to make fire and cook, can we belittle the first human beings who tried to make fire in ancient times? Isn't it ridiculous?"
"Sir, what you said is right. This statement should come to light!"
Ding Xiaobo was so impressed that he jumped up from the ground, picked up the wine bottle and said, "It seems that I will definitely lose today, but in this drinking game, sir, you can't even think of beating me."
"Oh, everything must be tested by practice. Even if it's a drinking competition, I may not lose."
Not to be outdone, Gongsun Linglong also grabbed the wine bottle, stretched out her hand and said, "Here, do it."
Ding Xiaobo looked at her, suddenly stunned for a moment, and then grinned: "Hahaha, okay, do it!"
The two wine bottles clinked together with a muffled sound, mixed with the sloshing of wine. The slight vibration was transmitted from the arms to the person's body. The two of them glanced at each other at the same time, and their eyes crossed in an instant.
