"... When the objective lens converges the distant light rays to a point, an eyepiece is placed behind it, and the distance between this point and the eyepiece is exactly equal to the focal length of the eyepiece. I told you before that the light emitted from the focus , after passing through the convex lens, it will become a beam of parallel light, and the distant scenery will be imaged, and the resulting image will be a magnified image. As for how many times it is magnified, it depends on the ratio of the focal length of the objective lens to the focal length of the eyepiece. Also, this tool that can see distant objects clearly is what I call a telescope!”
In the classroom, Li Zexuan's first class at Yanhuang Academy was gradually coming to an end. After half an hour of narration, he finally explained the principle of the telescope to the two people in front of him. Of course, it was just Kepler (composed of two convex lenses). He did not talk about the principles of telescopes, as well as the Galilean type (one convex lens and one concave lens) telescope and some reflecting telescopes.
"Oh~! It turns out that there is so much knowledge in this small lens. I never thought that a tool like clairvoyance can really be made! You are so knowledgeable, Master Shan~!"
As the saying goes, it is better to meet than to be famous. Although Mo Lingwei had heard from Mo Zhong and others that Li Zexuan was very powerful, at that time, Mo Lingwei felt that she was not bad, because she was like a "little bully" in the Mo family.
But after listening to what Li Zexuan said today, she finally understood the gap between herself and Li Zexuan: Although she knew a lot about the various knowledge of the Mohist family, she only knew a lot of it but didn't know why. And she knew those things It's very complicated and covers all categories; but Li Zexuan seems to have a complete system of knowledge. No matter what the problem is, he can trace it to its source and explain it completely. This makes Mo Lingwei have to admire it. Yes, she felt~!
"Haha~! When you two are free, you can read the college's physics textbook. Although this first volume does not cover much about lens imaging, some basic concepts are still very useful for making telescopes!"
Li Zexuan put down the chalk, clapped his hands, and smiled at the two of them.
"Yeah~! I'll take a look when I get back~!"
Mo Lingwei responded with a smile.
Yan Shaoning hesitated for a while and said: "Xiaoxuan, later on, you can give me a set of all the textbooks from the academy. I want to see them too~!"
Li Zexuan agreed, then he thought for a while and said: "After I have finished explaining the principles of the telescope to you, I have a task to give you~!"
As soon as she heard that there was a mission, Mo Lingwei immediately sat up straight and said: "Captain, tell us, we are listening~!" (The tragic Yan Shaoning was unknowingly represented again)
"In this Guanghua Building, the central main building that connects the two towers on both sides has an atrium in the middle of the fourth to sixth floors, with a semicircular glazed ceiling on the top. Do you know why I designed it like this? "
Li Zexuan supported the desk with both hands, looked at the two people in front of him, and asked.
Yan Shaoning frowned and was lost in thought. Mo Lingwei thought for a while, then shook her head and said, "I don't know, when I first saw it, I thought you created this atrium with a transparent ceiling specifically for lying down at night." Looking at the stars~!"
"Pa~!"
Li Zexuan patted the table and said with a smile: "Haha~! Miss Mo is right, this atrium is just for watching the stars at night~!"
Mo Lingwei was stunned. She just said that casually...
"According to my original idea, a large telescope is to be placed in this atrium, specially used to show students the stars and moon, so that they can understand what the world in the sky is like~!"
As soon as Li Zexuan said this, Mo Lingwei and Yan Shaoning both opened their mouths in surprise. They had only gotten telescopes because it was new and fun, but Li Zexuan... he wanted to use a telescope to look directly at the sky! this........
The ancients had always been in awe of the sky, so when Li Zexuan wanted to directly observe the sky, the two of them were so shocked that they could not speak for a while.
Li Zexuan smiled when he saw this and said: "Actually, the scene in the sky is not mysterious at all. You will understand when you really see it~! So the task I give you two is to build this large telescope. If it succeeds, His Majesty will surely be generous with the reward, and then all the credit will go to you~!"
Mo Lingwei came to her senses. She looked at Li Zexuan for a moment, then shook her head and said: "No, the method of making this telescope was obviously taught to us by the mountain chief. We cannot take the credit! I will not ask for your majesty's reward." ~!"
Li Zexuan was stunned, and just about to speak, he heard Mo Lingwei continue: "Although I don't want your Majesty's reward, if we really do it, I want the mountain chief to promise me a condition! How about~?"
Li Zexuan still doesn’t know exactly what this girl wants? He thought for a while and said: "I know what you want to say, Miss Mo. Let's do this. If you can really build this telescope, I will personally hire you, Miss Mo, as a distinguished professor of Yanhuang Academy. You will only be responsible for research, not teaching." , but the treatment is exactly the same as that of professors in the academy~! This is the biggest concession I can make~!"
If Mo Lingwei, a girl, comes to give lectures to the group of teenagers in the academy, Old Mo will probably fight for her~! Therefore, Li Zexuan could only ask Mo Lingwei to come to the academy to be responsible for scientific research.
Mo Lingwei thought for a while. Although she couldn't teach students, she could finally work at Yanhuang Academy. She no longer had to idle around all day long. And the most important thing was that she could get the treatment of a professor at the academy, which was better than that of her father. It’s all good~! So she nodded and said:
"Okay, Chief Shan, I promise you~!"
"Hey, no, I haven't agreed to make a telescope with you yet~?"
At this moment, Yan Shaoning, who had been silent for a long time, said weakly.
Li Zexuan felt in his heart that ten thousand grass and mud horses were galloping past. What a pig teammate~! Wasn't the reason why he gave Mo Lingwei this task to deliberately bring her and Yan Shaoning together? Otherwise, who can he ask for this task~? But.....
Alas, this should be the legendary straight man of steel, right?
"Hmph~! Xiao Ningzi, if you dare not agree, I will go and tell my dad right now that you bullied me in the office yesterday~!"
Mo Lingwei slapped the table, stood up and snorted angrily at Yan Shaoning.
When Li Zexuan heard this, his eyes widened. What do you mean? I dare you to say that Yan Shaoning, a sultry man, dragged this girl to the office yesterday to do something embarrassing~? Hey, this guy can do it~!
Yan Shaoning couldn't stand Li Zexuan's meaningful gaze, so he quickly stood up and explained: "Miss Mo, don't talk nonsense~! How did I bully you~?"
"Hmph~! I said yes, do you think my father believes in me or you~?"
Mo Lingwei put her hands on Xiaoman's waist and said.
Yan Shaoning immediately finished his words. After a while, he could only give in and said: "Okay, okay, then let me help you make a telescope~!"
"Hehe~! That's pretty much it~!"
The little girl's face changed at every turn. Mo Lingwei gave a sweet smile, and then she saw the sky outside the window and was shocked: "Oh~! It's so late, my dad should be worried about me, I should go home , but, it’s getting dark today, I...I..."
Seeing that she was obviously afraid of the dark but was embarrassed to say it, Li Zexuan said to Yan Shaoning: "Shaoning, it's so late and it's not safe for Miss Mo to be alone on the road. Go and give her a ride~!"
Obviously, he is creating opportunities for his brothers~!
But Yan Shaoning said dullly: "I'm not going down the mountain. I'm going back to the other courtyard in a moment! The bed in the other courtyard is more comfortable. Xiaoxuan, you'd better find someone else to send her off~!"
Li Zexuan's face was full of black lines, and he thought to himself, the straight man is destined to be alone for the rest of his life~! This guy has been single for so many years, but he is really special because of his ability. Last time, the eldest grandson wanted to be a matchmaker for Yan Shaoning, but now it seems that it was all in vain! As a single person based on your ability, you really have no choice~!
