摘要

Archimedes settles into his bath and observes the displacement of water, or so the story goes. Making a brilliant analytical leap, he decides that this phenomenon could be used to measure the volume of an object. By applying what is now known as the Archimedes Principle, he could then calculate the comparative density of that object. In reality, the term "specific gravity" is more appropriate, as this is the ratio of the weight of a given volume of material versus the weight of an equal volume of water, the common standard used to measure the specific gravity of solids.
