A 50-word short story by a China scientist.

One evening, Newton, who was meditating, subconsciously walked to the apple orchard in the backyard. In the garden, the apple trees are covered with ripe apples, and the air is filled with refreshing fruit fragrance, which Newton was completely unaware of.

Suddenly, with a click, a ripe apple on the tree was blown to the ground by the wind. Newton's idea jumped: Hey! Why don't apples fall into the sky? Is the gravity of the earth attracting it? !

Newton immediately made an association and extended it. People think that the force that the earth attracts apples is the same as the force that the earth makes the moon revolve around itself and the force that the sun makes the planets revolve around itself. It is concluded that gravity is also called "gravity".
