"… When the objective lens converges the distant light to a single point, the distance between the point and the eyepiece is equal to the focal length of the eyepiece. As I told you before, the light emitted from the focal point will become a parallel beam after passing through the convex lens, and the distant scenery will be formed into a magnified image. As for how magnified it is, it depends on the ratio of the focal length of the objective lens to the focal length of the eyepiece. In addition, this tool that can see distant objects clearly, I call it a telescope!"
In the classroom, Li Zexuan's first class in Yanhuang College was coming to an end. After an hour of lecture, he finally explained the principles of telescopes to the two people in front of him. Of course, he only explained the principles of the Kepler telescope (consisting of two convex lenses). There was also the Galileo telescope (one convex lens, one concave lens) and some reflector telescopes.
"Oh! I didn't know there was so much knowledge behind this small lens. I didn't expect that a telescope similar to clairvoyance could really be made! Yamachō, you're so knowledgeable! "
As the saying goes, knowing a person by reputation is not as good as meeting him in person. Although Mo Lingwei had heard from Mo Zhong and the others that Li Zexuan was very powerful, at that time, Mo Lingwei felt that she wasn't bad either. After all, she was like a "little overlord" in the Mo family.
However, after listening to Li Zexuan's lecture today, she finally understood the gap between her and Li Zexuan. Although she knew a lot about the various kinds of knowledge in the Mo family, she only knew the basics and didn't know the details. Moreover, the things she knew were very diverse and varied. On the other hand, Li Zexuan seemed to have a complete knowledge system. No matter what the problem was, he could trace it back to the source and explain it clearly. Mo Lingwei couldn't help but admire him. She felt that Li Zexuan was even better than her father ~!
"Haha! When you two are free, you can take a look at the school's physics textbooks. Although the first book doesn't cover much about lens imaging, some of the basic concepts are very useful for making telescopes! "
Li Zexuan put down the chalk and patted the chalk dust off his hands as he smiled at the two of them.
"Yes, yes! I'll take a look when I get back! "
Mo Lingwei replied with a smile.
Yan Shaoning hesitated for a while and said, "Xiao Xuan, give me a set of all the teaching materials of the academy later. I want to take a look too!"
Li Zexuan naturally agreed. Then he thought for a moment and said, "After explaining the principle of the telescope to you, I have a task for you!"
Upon hearing that there was a mission, Mo Lingwei immediately sat up straight and said, "Yamachō, go ahead, we're listening ~!" (The tragic Yan Shaoning was unknowingly represented again)
"In this Guang Hua Tower, in the middle of the central main building connecting the two towers on both sides, there is an atrium with a semi-circular glass ceiling at the top. Do you know why I designed it like this?"
Li Zexuan propped his hands on the lectern and looked at the two in front of him as he asked.
Yan Shaoning frowned and fell into deep thought. Mo Lingwei thought for a while and shook her head directly. "I don't know. When I first saw it, I thought that Yamachō designed this atrium with a transparent ceiling specifically for lying down and looking at the stars at night ~!"
Smack ~!
Li Zexuan slammed the table and laughed. "Haha ~! Ink Girl is right, this atrium is used for looking at the stars at night ~! "
Mo Lingwei was stunned. She was just casually saying it just now …
"According to my original idea, a large telescope should be placed in this atrium specifically for the students to look at the stars and the moon, so that they can understand what the world in the sky is like ~!"
As soon as Li Zexuan finished speaking, Mo Lingwei and Yan Shaoning both opened their mouths in shock. They got the telescope earlier because it was new and fun, but Li Zexuan … wanted to use the telescope to look at the sky directly! This …
The ancients had always been in awe of the sky, so the two of them were so shocked that they were speechless for a moment when Li Zexuan wanted to look at the sky directly.
Li Zexuan smiled and said, "Actually, the view in the sky is not mysterious at all. You will understand when you see it for yourself ~! So the task I'm giving the two of you is to build this large telescope. If you succeed, I'm sure His Majesty will reward you generously. When the time comes, all the credit will go to you ~! "
Mo Lingwei came back to her senses. She looked at Li Zexuan for a moment, then shook her head and said, "No, Yamachō taught us how to make this telescope. We can't take the credit! I also don't want His Majesty's reward ~! "
Li Zexuan was stunned. Just as he was about to speak, he heard Mo Lingwei continue, "Although I don't want His Majesty's reward, if we really do it, I want Yamachō to promise me one thing! How about it ~? "
Wasn't Li Zexuan very clear about what this girl wanted? He thought for a moment and said, "I know what you want to say, Ink Girl. How about this, if you can really make this telescope, I will personally invite Ink Girl to be a special professor at Yanhuang College. You will only be responsible for research and not teaching, but you will be treated exactly the same as a professor at the Academy ~! This is the biggest concession I can make ~! "
If he let Mo Lingwei, a girl, teach a lesson to those youths in their puberty, Old Man Mo would probably fight him to the death ~! Therefore, Li Zexuan could only let Mo Lingwei come to the Academy to be in charge of scientific research.
Mo Lingwei thought for a moment. Although she couldn't teach students, she could finally work at Yanhuang College. She didn't have to idle around all day, and most importantly, she could get the treatment of a professor at the Academy. It was better than her father's treatment ~! Therefore, she nodded and said,
"Okay, Yamachō, I promise you ~!"
"Hey, no, I haven't agreed to make the telescope with you ~?"
At this moment, Yan Shaoning, who had been silent for a long time, said weakly.
Li Zexuan immediately cursed in his heart. What a stupid teammate ~! Wasn't the reason why he gave Mo Lingwei this mission to set her up with Yan Shaoning? Otherwise, who couldn't he find for this mission ~? But …
Sigh, this should be the legendary iron-willed straight man ~?
"Hmph ~! Little Ning, if you don't agree, I'll go tell my father that you bullied me in the office yesterday ~! "
Mo Lingwei slammed the table, stood up, and snorted at Yan Shaoning.
Li Zexuan's eyes widened when he heard this. What did she mean? So Yan Shaoning, this outwardly passionate man, pulled a girl to the office to do something shameful ~? Heh, this kid is really something ~!
Yan Shaoning couldn't stand Li Zexuan's meaningful gaze. He quickly stood up and explained, "Ink Girl, you can't say things like that ~! When did I bully you ~? "
"Hmph ~! If I say you did, then you did. Do you think my father will believe me or you ~? "
Mo Lingwei said with her hands on her hips.
Yan Shaoning was speechless. After a while, he could only admit defeat and said, "Okay, okay, okay, I'll help you make the telescope ~!"
"Hehe ~! That's more like it ~! "
The little girl's face really changed quickly. Mo Lingwei laughed. Then, she saw the sky outside the window and was shocked. "Aiya ~! It's already so late. My father must be worried about me. I have to go home. But, it's getting dark, I … I … "
Seeing that she was obviously afraid of the dark but was too embarrassed to say it, Li Zexuan said to Yan Shaoning, "Shaoning, it's already so late. It's not safe for Ink Girl to be alone on the road. Why don't you send her off ~!"
Obviously, he was creating an opportunity for his brother ~!
However, Yan Shaoning said gloomily, "I'm not going down the mountain. I'm going back to the courtyard later! The bed in the courtyard is more comfortable. Little Xuan, you should find someone else to send her ~! "
Li Zexuan's face was full of black lines. He thought to himself, Iron men are indeed destined to be lonely for life! This guy has been single for so many years. It makes sense! Last time, Zhangsun wanted to matchmake Yan Shaoning, but now it seems like it was all in vain! You really can't do anything to a single person with his own ability ~!
