1632, Levin Hooke discovered and manufactured the microscope. At that time, his work was also very free, and he often polished his lenses when he was free from work. He often grinds while watching the gate and makes a magnifying glass. He suddenly thought of what would happen if he put them together, so he overlapped the two lenses and saw the skin on his hand, and made this amazing discovery. Then he made a simple microscope with these two lenses and discovered a brand-new microbial world.

There are many such examples in the history of science. It shows that science is not mysterious and truth is not far away. When playing, you need to be curious and be good at thinking. Then, let's be good at "playing" and make a name for ourselves!
