A group of people stared at this novel gadget, not knowing how to use it!
Wang Yuan explained the principle and demonstrated it again.
"Optical principles, convex and convex mirrors, concave and convex mirrors, this is the knowledge in physics!"
Xue Menglong, who has a quick brain, immediately opened the physics book he had just read and found the chapter on optical principles. He was so excited that he felt like he had found a treasure!
Lu Zhaolin doubtfully leaned on the convex mirror, first stretched his fingers underneath, and saw that the tiny hairs became extremely thick. He was immediately shocked and blank. Then he placed the glass piece with water droplets underneath, and saw the bacteria crawling inside.
I couldn’t help but be shocked: “Water, there are really bacteria in the water!”
"Let me see!"
Xue Menglong couldn't help it anymore, so he squeezed Lu Zhaolin, who was stunned, and lay under the microscope. After staring at it for a long time, he said with surprise and joy: "Really, there are really bacteria!"
Wang Zhonglou also squeezed in, followed by Yao Fuhai and Wang Haitian.
After reading it one by one, everyone was shocked and blank-faced, a little unbelievable!
Remember https://m in one second.
Dahu, Zhao Qinghe, and Hu Mengying on the side all pursed their lips. They had the same reaction when they first saw bacteria. They felt that the world had changed.
Wang Yuan stood aside quietly, waiting for the changes in the worldview of the five people.
"It's amazing!"
Wang Haitian reacted and patted Wang Yuan on the shoulder: "Brother Mingtan, every time I see you, I always feel strange. This time, I came to the right place!"
"Mr. Mingtan, we were arrogant just now, please forgive me!"
Lu Zhaolin and Xue Menglong looked at each other and in unison clasped their fists and bowed their heads.
After eating copper hot pot and reading mathematics, physics and chemistry books, they reacted!
Mr. Mingtan is really talented!
Just take out a chapter from three books and you can make a strange thing like a microscope!
If you understand everything, wouldn't you be able to make incredible things?
"He who does not know is not guilty!"
Wang Yuan smiled and waved his hand, then changed the subject and said: "Not all children can learn the things in these three books, and even if they learn them, they will not be able to get academic honors. Brother, you are responsible for arranging the children's courses and see who is suitable for learning.
Who can take the imperial examination with these things?"
"good!"
Wang Haitian nodded: "Teach students in accordance with their aptitude!"
Xue Menglong on the side couldn't help but said: "Mr. Mingtan, since a microscope can magnify small things, can we use this optical principle to make a mirror that can see distant things!"
Wang Yuan looked at Xue Menglong in surprise, turned to Erhu and asked Erhu to take out the telescope and handed it to him: "This is a telescope, but it can only magnify eight times and see eight miles away!"
Smart people have quick reactions and know how to see the subtleties and draw inferences from one example!
"Bali!"
Xue Menglong was shocked. As soon as he took the telescope, he was hit on the back of the head!
"Teacher comes first!"
Wang Haitian grabbed the telescope and, under Wang Yuan's guidance, began to look east and west.
For a time, a number one scholar, three high-ranking officials, and a dandy were all playing with telescopes like little children.
After a full hour, the five people put down the telescope after the novelty wore off!
The three of them gathered around the physics textbook and flipped through a few pages, their faces changed drastically and they frowned!
Taking a look at the chapter that the four masters and disciples saw, Wang Yuan immediately understood the reason - the movement of celestial bodies!
Wang Haitian smiled and said: "Mingtan, the earth, the moon, and the sun are really all big spheres floating in the void! The moon rotates around the earth, and the earth rotates around the sun. The sun carries the earth, the moon, and the sun with it.
Eighteen stars, rotating in the universe!"
"Yes!"
Wang Yuan waved, and Dahu sent another celestial teleportation model!
According to these few months, I will study the geography and constellations of this world.
Wang Yuan discovered that this seemed to be the earth, and somehow the history of the world had changed.
