Into the Ke Xue World by mistake

Chapter 97 Light-transmitting Lenses

"I worked as a pastry chef in Paris, and I came back to China to sort out my grandmother's belongings. When I was sorting out, I suddenly found a picture drawn by my great-grandfather, but it was a little broken in the middle."

Saying that, Kasaka Natsumi took out a piece of paper and spread it on the table.

Chairman Suzuki looked at the picture carefully, "Memories! They are indeed the eggs of memories!"

Immediately, he was a little uncertain, "But there are gemstones on it?"

Mori Kogoro on the side said: "Maybe there were gemstones on it originally, but they fell off later."

And Conan came over, and after looking at the picture for a while, he said, "Could it be that there were two eggs on it?"

A few people looked at him in surprise, and Conan continued: "Because you see, if there is only one egg, the outline of the egg will not fit together, so could it be that there are two eggs in the original picture, but the middle one is the egg? Parts of it were torn off."

Having said that, Conan picked up the egg of memory and looked left and right. Suddenly, under his manipulation, a piece of mirror fell off.

Mori Kogoro was a little angry, "What are you doing, brat!"

Conan hurriedly said: "A mirror has been dropped!"

Mori Kogoro widened his eyes, "What!"

Xiaolan on the side was also a little anxious, "Conan!"

On the other hand, Yuanzi hurriedly comforted: "It's okay, the mirror is easy to remove, it seems to be installed later."

Conan looked at the mirror with his eyes, and suddenly, his lens lit up.

"Mr. Nishino, please turn off the light."

Mori Kogoro was a little angry, "Hey, you kid, don't mess around!"

The lights were turned off, and Conan took out a watch-shaped flashlight and shone it on the lens.

An image of a castle is shone right on the wall.

Sirouf said in surprise, "Why do images appear?"

The general at the side said, "It's the magic mirror!"

"Magic mirror?"

Pusi Qinglan said: "I heard that there are magical mirrors in Japan and China."

Gan Jiangyi went on to say: "The mirror has been specially processed, and some hiding Catholics in Japan use the cross reflected on the wall to pray."

Xiaolan looked curiously at Yuki Shirakawa beside her, "Haina, do you know this kind of mirror?"

In her eyes, if you ask Haruna about something you don't understand, you can know the answer.

Hearing her voice, everyone on the side looked over like this white-haired girl.

Seeing everyone's curious gazes, Shirakawa Yuki nodded, "I do understand a little bit. This kind of mirror should be similar to a light-transmitting mirror."

"Light-transmitting mirror?"

Shirakawa Yuki nodded, "That's right, it is the light-transmitting mirror. The light-transmitting mirror is a bronze mirror with special effects called a "magic mirror" made in the middle and late Western Han Dynasty in China. It embodies the principles of optics and mechanics. The mirror gets its name because the pictures and texts on its back can be reflected on the wall under sunlight.

The light-transmitting mirror was first recorded in the "Mengxi Bi Tan" by Shen Kuo, a scientist in the Northern Song Dynasty of China: There is a light-transmitting mirror in the world, and there are inscriptions on the back of the mirror.In light of the sunlight, the inscription and the twenty characters are all reflected on the wall of the house, making it clear. "

Everyone nodded in understanding.

Conan on the side also lamented Shirakawa Yuki's wide range of knowledge.

Shirakawa Yuki continued: "As for its principle, there are many small uneven curvatures on the mirror surface. The mirror surface is slightly concave at the image and text, and the mirror surface is slightly convex at the non-image and text. The bright and dark parts corresponding to the image on the back of the mirror appear in the image, thereby forming the image on the back of the mirror.”

After listening to her explanation, everyone nodded, and Chairman Suzuki looked at her with admiration: "Your knowledge is really extensive, amazing!"

Shirakawa Yuki shook her head, "Chairman Suzuki is overrated."

President Suzuki smiled, "Hey, you are Sonoko's friend, just call me Uncle Suzuki."

Shirakawa Yuki smiled and said, "Okay, Uncle Suzuki."

Then the topic returned to the pattern.

Kasaka Natsumi looked at Mr. Sawabe at the side, and asked uncertainly: "Mr. Sawabe, this city?"

Sawabe nodded, "Yes, there is nothing wrong with Yokosuka's castle!"

Hearing what they said, Xiaolan asked curiously: "Is the castle in Yokosuka the one that often appears in advertisements?"

Kasaka Natsumi nodded, "That's right, that castle was built by my great-grandfather, and my great-grandmother is managing it."

Mori Kogoro said suddenly: "By the way, Miss Natsumi, as far as I know these two eggs were made by your great-grandfather, right?
Your great-grandfather once made these two eggs with your great-grandmother after the Russian Revolution and brought them back to Japan.

Maybe the Yokosuka castle was built after the gems on the second egg were sold off, and the first egg was hidden in the castle, and then this magic mirror was used to tell us this information. "

I have to say that Kogoro Mori's reasoning still makes sense.

Kasaka Natsumi searched for rice in the bag for a while, "Actually, besides the picture, there is also this old key. Is this what you mean?"

Mori Kogoro said firmly: "In my opinion, this is the key to the place where the second egg is hidden."

Sirouf touched his chin and said, "Dream egg studded with jewels!"

The general on the side also said: "If you find a value worth one billion, oh no, it must be worth more than 15 billion!"

At this moment, Kasaka Natsumi sent an invitation to Mori Kogoro, "Mr. Mori, when we arrive in Tokyo, I hope you can come to the castle with me, okay?"

Mori Kogoro agreed: "Of course no problem!"

Hearing this, Xiluoufu, Ganjiangyi, Hanchuanlong and Pusi Qinglan all rushed to go, which was agreed by Kasaka Natsumi.

……

"Be obedient and don't move!"

In the room, Xiaolan was gently bandaging the wound of Kidd's pigeon.

Xiao Lan said with a smile: "The bleeding has stopped, as long as the injury is cured, you can still fly."

Conan was also very happy, "Really? That's great!"

Xiao Lan sat down, "I don't know if Kidd is dead."

Shirakawa Yuki said with a smile: "That guy won't die so easily, don't worry!"

There was a knock on the door.

Xiaolan opened the door, and saw Han Chuan standing at the door holding the camera, "Not bad, that's the expression, I took it!"

After that, he turned and left.

Looking at his back, I really don't understand what he is doing.

At this time, Sonoko's voice sounded from behind, "Hey, Xiaolan, and Qingnai, I'm here to play with you!"

Looking back, I found Sonoko, Natsumi Kasaka, and Secretary Nishino.

Xiaolan invited them into the room together.

But for some reason, Secretary Nishino left in a hurry as soon as he entered the room, leaving Xiaolan a little confused.

Yuanzi laughed and said: "It seems that we have too many beauties here, he is shy! He is so cute."

Then, she said: "By the way, there is Miss Qinglan, I'll call her!"

　About what is the "magic mirror" in the magician at the end of the century, I didn't read it online, so I checked it myself and found that this kind of light-transmitting mirror made in the middle and late Western Han Dynasty in my country is the most similar. At the same time, it is a coincidence that , The light-transmitting mirror is also called the "magic mirror".

　　The reason why it is called a light-transmitting mirror is because when the light shines on the mirror, the pattern on the back of the mirror will be reflected on the wall opposite to the mirror.According to the research of relevant experts, it is believed that during the casting process of this kind of bronze mirror, the unevenness of the pattern pattern on the back of the mirror is different in thickness, resulting in casting stress after solidification and shrinkage, and compressive stress after casting, thus forming physical properties. deformation.When grinding to a certain extent, the elastic deformation acts superimposedly to produce a corresponding curvature between the mirror surface and the pattern on the back of the mirror, resulting in this light transmission effect.

　　Shen Kuo, a scientist in the Northern Song Dynasty, wrote in "Mengxi Bi Tan Qi Yong": There are light-transmitting mirrors in the world, and there are inscriptions on the back of the mirror.In light of the sunlight, the inscription and the twenty characters are all reflected on the wall of the house, making it clear.People have their own reasons. It is said that when casting, the thin part is cold first, but the back text is not thick, and after cooling, the copper shrinks more. Although the text is on the back, there are hidden traces on the mirror surface, so it appears in the light.Yu Guanzhi, reason and sincerity.However, Yu's family has three lessons, and I saw that the collections of other families are all the same. There is no slight difference in the writing, painting and inscriptions, and the shape is very ancient.Only this light is transparent, and other mirrors, even the thinnest, cannot see through.The ancient Italians had their own skills.

　　When I say this, I’m just more impressed by the wisdom of our ancient Chinese people. There are two light-transmitting mirrors from the Western Han Dynasty in the collection of the Shanghai History Museum.
