Archimedes' principle
アルキメデスの原理あるきめですのげんりArchimedes' principle is a law of physics that explains how objects behave when they float in a liquid. According to this principle, an object immersed in a liquid experiences a buoyant force equal to the weight of the liquid it displaces. The principle is also applied to measuring the specific gravity, sake meter value (SMV), and alcohol content of sake. Specifically, the specific gravity of sake is determined from the density of the liquid being measured, and the result helps in understanding the characteristics of the sake. Archimedes' principle plays an important role in evaluating the quality of sake.
