Ahem! Miss Mo! Are you still busy? "
After repeatedly promising to Sun Simiao that the microscope would be delivered within a month, Li Zexuan came out of the other courtyard and wanted to find Mo Lingwei in another courtyard. However, he was told by the servants in the other courtyard that Mo Lingwei was in the workshop, so Li Zexuan had to go to the cloud. Shan, came to the workshop and found Mo Lingwei in a small room next to the steel plant.
"Chief Shan~?"
Mo Lingwei raised her head, looked at Li Zexuan with a look of surprise, and said: "Shan Chief, you are here! In the past month or so, I have understood all the principles of the generator! Now I am letting the masters in the workshop Try making it!"
"Oh~?"
Li Zexuan raised his eyebrows in surprise and said happily: "Miss Mo is really gifted to be able to take advantage of the generator so quickly! Ahem! But there is no need to worry about the generator now. There is a more urgent matter at the moment. Miss Mo, do it!”
Mo Lingwei frowned slightly dissatisfied. She was not the kind of person who liked to give up halfway. "Chief, what else could be more urgent than this generator? According to my estimation, in more than half a month, I Then we can build the generator, can you delay the matter for a while?"
Although this girl is usually fierce and careless in front of Yan Shaoning, she is still quite restrained when facing Li Zexuan. After all, Li Zexuan is simply too perfect. His knowledge and martial arts are all at the level of a master. The more he understands him, Li Zexuan, the more you feel like you are looking up at a high mountain! Therefore, she still respects Li Zexuan, the headmaster of the academy. After all, a master is a teacher!
If Yan Shaoning said these words now, it would be strange if Mo Lingwei didn't get angry!
"More than half a month! Miss Mo seems to be very confident~!"
Li Zexuan smiled slightly and said: "The dam will not be built within half a month, and even if the generator is built, I'm afraid it will be of no use~! And my matter is not difficult for Miss Mo. , it is estimated that it will be completed in less than half a month~!"
Hearing this, Mo Lingwei frowned and thought for a while, then finally nodded and said, "Okay then! Chief, what are you talking about~?"
Li Zexuan said: "Miss Mo, a medical school is about to be established over at the academy. I plan to ask you to build a microscope for the medical school. The previous astronomical telescope was for seeing stars thousands of miles away, and this microscope is for seeing clearly. Tiny objects or living things that are invisible to the naked eye around us!”
Mo Lingwei asked curiously: "Chief, isn't this the magnifying glass you are talking about? I have made one for Master Liu and the others before! Besides, are there any small things that cannot be seen with the eyes?"
Li Zexuan was helpless. The textbooks in the academy included mathematics, physics, chemistry, and geography, but not biology. Therefore, not only did Mo Lingwei not know the concept of bacteria, but all the teachers and students in the academy did not.
The reason why he did not include biology as a teaching subject in the academy at the beginning was because of his own considerations.
The most basic theoretical foundation of biology is the theory of evolution. If he writes in a book that humans evolved from monkeys, it will cause an uproar. Will Li Er, who calls himself the True Dragon Emperor, spare him? How could the descendants of Yan and Huang in the world spare him?
Darwin proposed the theory of evolution in the 19th century. At that time, the power of the church was greatly weakened, and the scientific system in Western countries had been formed. The trend of tolerance had already begun, and there was great tolerance for a hypothesis. Of course, the most important thing was Darwin's theory of evolution. There is really no attack on God anywhere, so the church believes that Darwin did not oppose God.
In today's Tang Dynasty, the common people are still ignorant, and everyone still believes in the myth that human beings were created by Nuwa. It is really inappropriate to propose the theory of evolution! So when Li Zexuan founded Yanhuang Academy, he completely banned the biology course!
Of course, there must be many unreasonable things in doing this, which is not conducive to the development of medicine. He may release an abridged version of the "Biology" textbook later, but that is a story for another day!
"Miss Mo! A microscope is not the same as a magnifying glass. Its magnification is higher than that of a magnifying glass, and the things you see are clearer! As for things that are invisible to the naked eye, Miss Mo, have you ever seen rotten meat?"
Li Zexuan pondered for a moment and smiled.
Mo Lingwei was a little confused. She was stunned and replied: "Of course I have seen carrion. Chief, why are you talking about this?"
Li Zexuan smiled and said: "The reason why this meat will rot after being left for a long time is actually because there is a very small, very small bug in the air we breathe. Some of these bugs will eat the meat. They can digest the meat, so over time, the meat will completely rot!"
When Mo Lingwei heard this, her expression suddenly became frightened. She quickly covered her nose, widened her eyes, and said: "Shan... Chief Shan, then... wouldn't there be many small insects that can pass through our mouths?" The nose enters the body! It’s over, I’m about to turn into a pile of rotten flesh! I’m still young, and I don’t want to die yet!”
At the end, you could hear a hint of crying in this girl's voice!
Li Zexuan rolled his eyes helplessly, somewhat dumbfounded: "Ahem! Miss Mo, although it is true that some small bugs can enter the human body through the air, there are many things in our body that can kill small bugs, so only the body of a dead person can Rotting, living people will not! Miss Mo, please stop worrying about it!"
Mo Lingwei blinked her eyes and then put down her slender hands covering her mouth and nose. After holding it in for a while, the girl's face turned red. She quickly took a few breaths and said slightly angrily: "Huh~! Scared! It’s killing me! Chief, why didn’t you tell the whole story? It made me think I was going to rot!”
Li Zexuan was speechless. He thought to himself, "You are the one who makes so much trouble. Do you still blame me?"
"Okay, Miss Mo, let's get down to business. Let me tell you about the structure of a microscope~!"
Li Zexuan coughed twice, and then saw that there happened to be chalk and a small blackboard in the room. He walked to the blackboard, picked up the chalk, and began to draw while talking: "The simplest microscope is actually a convex lens, but this The convex lens is somewhat special. It has a large curvature, a short focal length, and a much larger magnification than an ordinary convex lens. Of course, grinding this kind of convex lens will test the skill of the lens grinder!
What I’m talking about to Miss Mo today is not this single convex lens type magnifying glass, but a magnifying glass composed of two convex lenses. One has a long focal length and is called the objective lens, and the other has a short focal length and is called the eyepiece. The light reflected by the object is imaged through the objective lens for the first time. At this time, the object should be between one and twice the focal length of the objective lens, forming a magnified inverted real image, and then the first image of the object is used as the "object" , the second imaging through the eyepiece..."
