Chapter 102 Telescope!

Li Lizhi added yearningly: "Brother Xuan said that he has traveled all over the world, and there are many countries in distant lands, but we don't know about it now."

"I also really want to go to those distant lands and appreciate the customs and customs of various countries!"

After she finished speaking, she continued to walk forward.

The boundless sea of ​​flowers is like a fairyland on earth!

The colorful butterflies are flying, and the bees are dancing, as if they are frolicking and cheerful elves among the flowers!

A burst of refreshing fragrance of flowers surrounds them, making people extremely intoxicated!

Everyone walked extremely slowly, and the scenery along the way was pleasing to the eye!

Everyone walked through the long Huashiyong Road before turning back.

But the group is still full of joy, with joy on their faces.

Li Lizhi returned to the gazebo at the entrance of the garden with a group of maids.

I saw Lin Xuan looking at the pleasant scenery in the distance with a telescope.

Li Lizhi approached Lin Xuan slowly step by step, and asked happily: "Brother Xuan, what are these pair of long black utensils you are holding in your hand? Why have I never been in the house?" seen?"

Lin Xuan turned his head and looked back when he heard the words, a gust of breeze came slowly.

Behind Li Lizhi, peach blossoms are in full bloom in the distance.

And the Li Lizhi in front of her is charming and beautiful, her face is like a peach blossom!

She has bright eyes and white teeth, and her eyes are flowing, like full autumn water, and her shallow willow and black eyebrows are like a crescent moon.

A pair of slender hands are like catkins, and the skin is as tender as fat.

Li Lizhi's sparkling eyes were as bright as stars, and she stared at him with admiration.

Lin Xuan was startled after looking at each other, and replied lightly: "This is a telescope. You can also call it a telescope."

"I just finished the first one, and I'm testing some parameters such as its field of view and resolution, so that I can make some adjustments and corrections."

Li Lizhi's beautiful eyes were full of curiosity.

"The telescopic mirror?"

"Brother Xuan, what is this telescope?"

"What are binoculars for?"

Lin Xuan explained lightly: "This telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects."

"It is an instrument that enables people to see distant scenery and magnifies the distant scenery so that people can see the details in the distance."

"To put it simply, wearing this binoculars can make you see the scene thousands of meters away, as if you were zooming in on the 100 meters in front of your eyes."

hiss!

As soon as the words fell, everyone was surprised!

The first few sentences are naturally incomprehensible, but the last sentence. . . . .

It's too scary!

That's not what they are doing thousands of meters away, you can see clearly with the binoculars!

All the maids of the Lin Mansion were terrified!

Alas!

Cover your face!

Never dare to be lazy again!

"So amazing?" Li Lizhi's eyes lit up when she heard this!

"Brother Xuan, can you show Changge?" Li Lizhi asked anxiously.

"Okay." Lin Xuan said lightly.

Then he passed the telescope in his hand to Li Lizhi.

Li Lizhi took the binoculars, put them in front of Lin Xuan's eyes, and opened them wide.

I saw the scenery a thousand meters away from where she just walked, as if it was right in front of my eyes, within reach, and clearly!

Amazing!

Li Lizhi cherry opened her small mouth slightly, her eyes were round and round, with a look of surprise on her face!

Li Lizhi took down the telescope in front of her and asked in amazement, "Why is this telescope so magical?"

Lin Xuan told the maid indifferently after hearing the words: "Go, get some ice and an awl."

Li Lizhi was puzzled when she heard the words, not knowing why.

Brother Xuan, what are you going to do?

Lin Xuan said to Li Lizhi indifferently: "Mozi once did a small hole imaging experiment, have you ever heard of it?"

As soon as these words came out, Li Lizhi's beautiful eyes widened instantly.

At this time, Lin Xuan explained lightly: "There is a record in the "Mo Jing": when the scene arrives, there will be an end at noon, and the chief of the scene. Say it at the end."

"Scenery. People of light, if they shine, those who are below are also high; those who are tall are also down. The feet cover the light, so the scenery is above; the head covers the light, so the scenery is below. There are distances and nears. Duan, with Yu Guang, is also inside the old scene storehouse.”

"What this describes is actually pinhole imaging."

Fortunately, Li Lizhi was familiar with many books in the palace. When she first read this record of small holes, she found it extremely novel and interesting, so she was more impressed, and she still remembers it clearly.

"Changge has read this paragraph before, but what does the small hole imaging have to do with the telescope?" Li Lizhi asked with a puzzled expression.

Lin Xuan was a little surprised when he heard the words, and then happily explained: "Don't worry, Changge, listen to me and speak slowly."

"This Mozi is the first person to do small hole imaging experiments."

"He has a lot of research in optics. Including plane mirrors, concave mirrors, and convex lenses."
