Otaku Engineer in Great Tang Dynasty

"...When the objective lens converges the distant light at a point, the eyepiece is placed behind the eyepiece, and the distance between this point and the eyepiece is exactly equal to the focal length of the eyepiece. I told you earlier that the light emitted from the focal point After passing through the convex lens, it will become a beam of parallel light, and the distant scene will be imaged, and it will become a magnified image. As for the magnification, 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 at Yanhuang Academy is gradually coming to an end. After half an hour of recounting, he finally explained to the two people in front of him the principle of the telescope, of course it was only Kepler (composed of two convex lenses) The principle of telescopes, Galileo type (a convex lens, a concave lens) telescope and some reflective telescopes, he did not explain.

"Oh~! It turns out that there is such a big knowledge in this small lens, and I didn't expect that tools similar to clairvoyance can really be made! Shanchang, you are really knowledgeable~!"

As the saying goes, being famous is not as good as meeting. Although Mo Lingwei had heard of Li Zexuan from Mo Zhong and others before, Mo Lingwei felt that she was not bad at that time, because she was a "little bully" in the Mo family.

However, after listening to what Li Zexuan said today, she understood the gap between herself and Li Zexuan: Although she knew a lot about the various knowledges of the Mo family, many of them only knew what was happening and didn’t know why, and she knew those things. It's very complicated, and there are all kinds of categories; but Li Zexuan seems to have a complete knowledge system. No matter what the problem is, he can trace the origin and explain it completely. This makes Mo Lingwei have to admire Now, she thinks Li Zexuan is better than her father~!

"Haha~! When you are free, you can look at the physics textbooks of the academy. Although this first volume does not involve much in lens imaging, some basic concepts are still very useful for making telescopes!"

Li Zexuan put down the chalk, and smiled at the two of them while clapping the chalk dust on his hands.

"Hmm~! I'll see when I go back~!"

Mo Lingwei responded with a smile.

Yan Shaoning hesitated for a while, and said, "Xiao Xuan, you will send me a set of all the teaching materials of the academy when you turn around. I want to see it too~!"

Li Zexuan agreed, and then he thought for a while and said: "After I have explained the principle of the telescope with you, I have a task to hand to you~!"

Upon hearing that there was a task, Mo Lingwei immediately sat upright and said, "Shan Chang, you said, let's listen~!" (The tragic Yan Shaoning was represented again without knowing it)

"In this Guanghua Building, the central main building that connects the two towers on both sides, in the middle of the fourth to sixth floors, there is an atrium with a semi-circular glazed zenith on the top. Do you know why I designed it this way? "

Li Zexuan held the table with both hands, looked at the two people in front of him, and asked.

Yan Shaoning frowned and fell into bitter thoughts. Mo Lingwei thought for a while, and shook her head directly: "I don't know, when I first saw it, I thought that Shan Chang, you made this transparent zenith atrium, which is used to lie down at night. Watching the stars~!"

"Slap~!"

Li Zexuan patted the table and smiled: "Haha~! Miss Mo is right, this atrium is used to watch the stars at night~!"

Mo Lingwei was stunned, she just said that casually...

"According to my original assumption, a large telescope is to be placed in this atrium, which is specially used to show the stars and the moon to the students, so that they can understand what the world in the sky is like~!"

As soon as Li Zexuan said, Mo Lingwei and Yan Shaoning opened their mouths in surprise. They used the binoculars just because they were new and fun, but Li Zexuan is...this is to look at the sky directly with the binoculars! This........

The ancients have always been in awe of the sky, so when Li Zexuan wanted to observe the sky directly, the two of them were shocked to be unable to speak for a while.

Li Zexuan smiled when he saw it, and said, "Actually, the scene in the sky is not mysterious at all. When you really see it, you will understand~! So the task I entrusted to you is to build this large telescope. If it succeeds, I think your Majesty will not hesitate to reward him, and all the credit will go to you then~!"

Mo Lingwei woke up, she looked at Li Zexuan for a moment, then shook her head and said, "No, the method of making this telescope was clearly taught to us by the head of the mountain. We can't take this credit! I won't want your majesty's reward. ~!"

Li Zexuan was taken aback. Just when he wanted to speak, he heard Mo Lingwei continue to say: "Although I don't want your majesty's reward, but if we really do it, I want Shanchang to promise me a condition! How about~?"

Isn't Li Zexuan clear what this girl wants? He thought for a while and said, "I know what Ms. Mo you want to say, so be it. If you really can make this telescope, I will personally hire Ms. Mo as a distinguished professor of Yanhuang Academy. You are only responsible for research, not for teaching. , But the treatment is exactly the same as the professors of the college~! This is the biggest concession I can make~!"

Let Mo Lingwei be a girl, come forward to give lectures to the adolescent Sao Nian in the academy, and Old Man Mo will try to find himself~! Therefore, Li Zexuan could only let Mo Lingwei come to the academy to be responsible for scientific research.

Mo Lingwei thought for a while. Although she can't teach students, she can finally work in Yanhuang Academy. She doesn't need to idle all day long, and the most important thing is that she can get the treatment of a college professor, which is better than her father's treatment. All good~! So she nodded:

"Well, Shan Chang, I promise you~!"

"Eh, no, I haven't agreed to make a telescope with you~?"

At this moment, Yan Shaoning, who had been silent for a long time, said weakly.

Li Zexuan suddenly felt 10,000 heads of grass and mud horses galloping past. He is really a pig teammate~! Isn't the reason why he gave Mo Lingwei the task to match her with Yan Shaoning? Otherwise, who can't he find for this task~? but.....

Alas, this should be the legendary steel straight man~?

"Huh~! Xiao Ningzi, if you dare not agree, I will tell my father that you bullied me in the office yesterday~!"

Mo Lingwei patted the table~www.ltnovel.com~ and got up and snorted angrily at Yan Shaoning.

Li Zexuan's eyes straightened when he heard it. What do you mean? Dare to love Yan Shaoning, the boring man yesterday, dragged the girl to the office to do something shameful~? Hey, this kid is fine~!

Yan Shaoning couldn't stand Li Zexuan's meaningful gaze, and quickly got up and explained: "Miss Mo, you can't talk nonsense~! Where can I bully you~?"

"Huh~! I said there is, do you say that my father believes in me or believes in you~?"

Mo Lingwei crossed Xiaoman's waist and said.

Yan Shaoning suddenly concluded. After a while, he could only admit it and said: "Okay, OK, then I will help you make a telescope together~!"

"Hehe~! This is almost the same~!"

The little girl's face really changed. Mo Lingwei smiled and saw the sky outside the window, she was shocked: "Oh~! It's so late, my father should worry about me, I should go home. , But it's going to be dark this day, I...I..."

Seeing her seemingly afraid of the dark, but embarrassed to say, Li Zexuan said to Yan Shaoning: "Shaoning, it's so late, it's not safe for Miss Mo to be on the road alone, you can send her a ride~!"

Obviously, he is creating opportunities for his brothers~!

But Yan Shaoning said dullly: "I won't go down the mountain. I will go back to the other courtyard for a while! The bed here is more comfortable. Xiaoxuan, you should find someone to send her off~!"

Li Zexuan's face was full of black lines, and his heart said, the straight steel man is destined to be alone for life~! For so many years, this manifest is really special because of his ability. Last time the eldest grandson wanted to match Yan Shaoning, but now it seems that he should be blind! If you are a single person, you really can't do anything about him~!
