By the way, this thing is recorded in Mozi, don’t they know about it?
"When a scene arrives, it has an end at noon, and when the scene is long, it is said to be at the end."
"Scenery. The person with the light is like a ray of light. Those who are below are also high; those who are high are also below. The foot covers the lower light, so the scenery is above; the head blocks the upper light, so the scenery is below. There are things far and near.
Duan, Yu Guang, so it is also inside the scenery library."
And shadow puppetry is based on this principle, so they shouldn't know it.
If you don't understand, just ask. Chen Yuan directly asked Zhao Yun: "Zilong, do you know Mozi?"
Zhao Yun nodded: "Mozi is the sage of the Mohist family. He has the power of ghosts and gods, so Yun naturally knows it."
The sages of the Mohist family are right, what kind of unexpected power are these ghosts and gods?
Ignoring it for now, Chen Yuan continued to ask: "Then do you know the image of the small hole?"
Zhao Yun thought for a moment: "I don't know Yun."
???
you do not know?
Chen Yuan was a little surprised. Could it be that Mozi's things were not passed down?
Chen Yuan was thoughtful and walked to the courtyard door: "Sir, please see me."
After saying this, the courtyard door opened automatically without any wind.
Chen Yuan has long been accustomed to this. As a master, you have to show your strength.
If someone opens the door, why would he be called an expert?
Chen Yuan walked into the room, and Tong Yuan looked at Chen Yuan: "Did you do it, little friend?"
Chen Yuan did not answer Tong Yuan's question, but asked: "Sir, I have a question."
Tong Yuan smiled and said, "If you have something to say, it doesn't hurt to say it."
"Sir, do you know what the Mohist's pinholes look like?"
Tong Yuan thought for a while: "I know about the Mohist family. The ancestor of the Mohist family, Mozi, had earth-shattering cultivation. He understood the changes of heaven and man, and reached a state of transcendence. But what is the image of the small hole?"
"Rebirth of the Great Era of Fighting Waves"
Chen Yuan suddenly understood.
Probably many things from the Mohist family have been lost.
This includes pinhole imaging. The so-called shadow play is probably what people think of when they see their own shadows falling on the wall in daily life. It may have nothing to do with the Mohist pinhole imaging.
Okay, let me give you some popular science.
Chen Yuan walked to the window and looked at the sky. The sun was setting over the western mountains, with afterglow spreading all over the sky. The scenery was indeed magnificent.
After a while, the night finally fell on the day.
Chen Yuan asked someone to light a lamp and then brought over a piece of white paper.
There are Tong Yuan and Zhao Yun in the house.
Chen Yuan said to the two of them: "Next, I will demonstrate what small hole imaging is, that is, making a small thing bigger."
Hearing this, Tong Yuan and Zhao Yun both became energetic and stared at Chen Yuan intently to see what Chen Yuan was going to do.
Even Tong Yuan secretly released his aura to cover the entire valley. Whenever there was any slight movement, he would receive a full blow from the world's most powerful master.
Tong Yuan did it silently, and Chen Yuan didn't feel it at all.
Chen Yuan used the tip of his sword to poke a small circle of holes in the center of a wooden board.
The diameter of the small hole is about three millimeters, try to hold it upright on the table.
Then hold the candle and place it near the small hole.
Take a piece of white paper and place it on the other side of the hole.
Then a magical scene happened, an inverted candle flame appeared on the white paper.
Chen Yuan moves the candle. When the white paper is closer to the candle, the image is small and bright; when the white paper slowly moves away from the candle, the image gradually becomes larger and the brightness becomes darker.
Confusion flashed in the eyes of Tong Yuan and Zhao Yun, and they had no idea why.
Chen Yuan then ended his experiment.
He once again punched several holes of different sizes and shapes in the wooden board, with a few centimeters between the holes.
At this time, several inverted images corresponding to the small holes appeared on the white paper.
They are all the same size, but have different degrees of clarity. The larger the hole, the clearer the image.
As long as the hole is small enough, its shape, whether square, round, or oblate, has no effect on the clarity or shape of the image.
Seeing this scene, Tong Yuan and Zhao Yuneng were even more confused.
After Chen Yuan finished the experiment, he looked at Tong Yuan and Zhao Yun: "Does this count as using a small thing to become a big thing?"
Indeed, Chen Yuan's small hole image actually magnified the candle.
To be honest, if glass with relatively high purity had not been created yet, Chen Yuan could have invented the magnifying glass and telescope, which would have made a small thing bigger.
Since Chen Yuan has done it, Tong Yuan will definitely not deny it.
However, he didn't understand the reason at all.
Tong Yuan nodded first: "You have passed the test of growing from a small person to a big person."
"But, what is the truth of this, please give me some advice."
Tong Yuan is indeed a great master. He just asks questions when he doesn't understand. There is no such thing as pretending to understand something that he doesn't understand and pretending to be a master.
Although Zhao Yun did not speak, he was still full of doubts.
Naturally, Chen Yuan had no intention of being self-conscious.
"This small hole imaging is related to a science, which is called the science of light. If we want to know why there are small hole imaging, we must first know, what is light?"
"Sir, Zilong, do you know what light is?"
Tong Yuan and Zhao Yun started thinking.
Light is the most common thing, but what is light? uukanshu.com www.uukanshu.com They really haven't studied it yet.
Now suddenly asked by Chen Yuanyi, Tong Yuan and Zhao Yun really couldn't tell for a while.
Chen Yuan secretly laughed, let alone you, even modern people in his world would probably be confused if you suddenly asked a person what light was.
The Taoist sage Lao Tzu once said that light and dust are the same.
There are also sentences in the Chu Ci that are like the sun and the moon. The poems about "Ye Wei Yang" and "Ting Liao Zhi Guang" in the Book of Songs are even more fascinating.
But what exactly is light?
Of course Chen Yuan would not talk to Tong Yuan and Zhao Yun about the philosophical meaning of light, that would be too complicated.
Therefore, Chen Yuan only talked to two people about light in the physical sense.
"Light is both a wave and a particle."
"Under normal conditions, light travels in straight lines."
"Under some conditions, light travels in the form of waves, just like water waves."
"The speed of light is extremely fast. With such a long distance from the sun to the earth, it does not take a quarter of an hour for light to reach it."
Then, Chen Yuan used his superficial knowledge of physics to give the two people a popular science lesson on optics.
Although there were some parts that Tong Yuan and Zhao Yun did not understand, there were many things that both of them understood.
Zhao Yun understood one of the mysteries of light, extreme speed.
And Tong Yuan suddenly understood the mystery of the integration of light and darkness.
Where there is darkness there is light, and where there is light there is darkness.
After comprehending one of the mysteries of light, Tong Yuan felt the invisible heavenly ban trembling even more fiercely.
Tong Yuan's eyes became brighter and brighter.
Could it be that my opportunity really lies with this boy?
A test has given me some insights, and even the heavenly ban began to loosen and tremble.
If he is really allowed to complete these three things, he might be able to break the ban.
If that's the case, why not go to Xiangyang with him!!!
