What does the story of Cao Chong calling himself an elephant inspire you?

Inspiration: Be good at thinking and finding ways when things happen.

"Cao Chong called an elephant" is a story almost known to all women and children in China. Cao Chong, who is only six years old, used the physical principle that the gravity of the object floating on the water is equal to the buoyancy of the water to the object, and solved a big problem that even many learned adults were at a loss. This is a miracle.

In fact, the clever Cao Chong's method is "equal replacement method". Many stones are used to replace elephants, marks are carved on the ship's side, so that elephants and stones have equal effects, and the weight of stones is weighed again and again, so that "big" can be transformed into "small", and this problem can be solved satisfactorily.

Equivalent substitution method is a commonly used scientific thinking method. Here is another short story of Edison.

Edison, a great American inventor, had an assistant named Aptom who had a good foundation in mathematics. Once, Edison handed the glass shell of an electric light bulb to Aptom and asked him to calculate the volume of the light bulb.

Aptom looked at the pear-shaped bulb shell, and after thinking for a long time, he drew a sectional view and a three-dimensional view of the bulb shell, drew a series of complicated curves, measured data one by one, and listed a series of formulas.

after several hours of intense calculation, no result has been reached. Edison was very dissatisfied after reading it. I saw Edison fill the bulb shell with water, and then poured the water into the measuring cup. In less than a minute, he "calculated" the volume of the bulb. Here, Edison replaced the volume of the bulb shell with the volume of water poured into the measuring cup, and also used the equivalent replacement method.
