More than 2,000 years ago, Chinese scholar Mozi discovered an interesting phenomenon - light coming in from small holes will form an inverted image of the outside scene on the opposite wall. This phenomenon is what he calls "small hole imaging"...
I looked at the above story and had a few questions in my mind: Why does Mozi call this phenomenon "small hole imaging"? What is the principle of "small hole imaging"?
I thought about it, my head was going to explode, but I still couldn't think of the slightest answer. Suddenly, my brain was hot and my body was vibrating, so instead of consuming brain energy here, I should practice it! There is a saying that practice is the only way to test truth!
Just do it. I pulled out a translucent plastic film, paper cups, rubber bands and candles. Secondly, I carefully draped translucent plastic over the paper cup and then tightened it with leather. After that, use the tip of the pen to tie a small hole in the bottom of the cup, and finally light the candle, point the hole at the small flame, adjust the distance between the cup and the candle, until you can see a clear image...
Wow, a clear scene appeared in front of my eyes, and I watched it for half an hour at once, until my mother called me to eat and then I couldn't put down the paper cup.
This experiment gave me great self-confidence and at the same time gave me a full sense of accomplishment, which is amazing!
