Li Lizhi added yearningly: "I heard from brother Xuan that he has traveled all over the world. There are many countries in far-flung lands, but we don't know about it now."
"I also really want to go to those far-flung foreign lands and appreciate the customs and customs of various countries!"
After speaking, she continued to walk forward.
The boundless sea of ??flowers as far as the eye can see is like a fairyland on earth!
The colorful butterflies are flying, and the bees are dancing, as if they are playing and cheerful elves among the flowers!
Bursts of refreshing and fragrant floral fragrance surround them, making people extremely intoxicated!
Everyone walked extremely slowly, and the scenery along the way was pleasing to the eye!
All the people walked through the long flower-stone corridor before turning back.
However, the group of people 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 charming, she really looks like a peach blossom on a human face!
She has bright eyes and white teeth, 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, looking forward to brilliance, and staring 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.
"A binoculars?"
"Brother Xuan, what is this telescope?"
"What is the 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 will allow you to view the scene a thousand meters away, as if you were zooming in on a hundred meters in front of your eyes."
Hiss!
As soon as the voice 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!
Woohoo!
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 nervously.
"Okay." Lin Xuan said lightly.
Immediately 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 that she just walked over, as if it was right in front of my eyes, within reach, and clear!
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 off 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: "It is recorded in the "Mo Jing": When the scene arrives, there is a Duan at noon, and the chief of the scene. Say it at Duan."
"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, soThe scenery is on the top; the head covers the top light, so the scenery is on the bottom. There is an end to the distance, and it is in the light, and it is also in the old scene library. "
"What this describes is actually pinhole imaging."
Fortunately, Li Lizhi was familiar with many books in the palace. When she first read the record of the small hole image, 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 conduct small hole imaging experiments."
"He has a lot of research in optics. Including plane mirrors, concave mirrors, and convex lenses."
"And these are the principles and materials needed to make a telescope."
"To make this telescope, the best material is crystal, followed by glass." (Remember this site URL: www.hlnovel.com - Didn't finish reading?
