Extended information

In order to understand the properties of a certain thing, many ancient scientists often made qualitative analogies between the thing and known things, that is, the two were similar. Many properties, it is inferred that these two things also have other similar properties.

For example, in order to understand the propagation of sound, Song Yingxing, an ancient Chinese scientist, said in "On Qi: Momentum": "Things that move Qi are just like water that stirs water. ... Throwing a stone at it Water, where the surface of the water meets the stone, stops with a punch, and its waves spread out one by one, searching for the text in all directions without stopping. The same is true here."

, Song Yingxing compared the sound of hitting an object to the ripples of a stone hitting water. Since water spreads in waves, sound can also spread in waves. Song Yingxing applied qualitative analogy here and inferred that sound propagates in the form of waves in the air.
