• Areometric — Belonging or relating to an hydrometer (areometru), or based on measurements carried out using this hydrostatic instrument utilized to determine the relative density of liquids or the concentration of solutions. In a structural technical sense, it describes a method, a graduated scale, or an experimental procedure based on Archimedes' principle, used in laboratories for analyzing industrial fluids, dairy products, or alcoholic beverages.
• Areometry — A branch of metrology and applied physics dealing with the study of techniques, methods, and mathematical principles for measuring the density or specific gravity of liquids using hydrometers. In a structural-engineering sense, areometria is based on Archimedes' principle regarding the equilibrium of floating bodies, serving as an essential quality control factor in chemical, petroleum, food, and winemaking industries.
• Hydrometer — A measuring instrument consisting of a sealed glass tube, equipped at its lower part with a ballast bulb filled with shot or mercury and at its upper part with a thin graduated stem, used for the direct determination of a liquid's density or specific gravity. In a structural sense, its operation is based on variable vertical immersion in the fluid depending on its density, the level to which the stem sinks indicating the desired value on the scale.
• Archimedes — An ancient Greek scientist, mathematician, physicist, astronomer, and engineer (3rd century BC), born in Syracuse, considered one of the greatest scientists in human history; discoverer of the principle of hydrostatics and inventor of numerous war machines. Figuratively and culturally, his name is used to evoke absolute inventive genius, sudden scientific inspiration, or rigor demonstrated in solving complex technical problems.
