All matter has density. The recorded uses of density to characterize matter date back to as early as ca. 250 BC when Archimedes was believed to have solved "The Puzzle of The King s Crown" using density. 1 Today measurements of density are used to separate and characterize a range of materials (including cells and organisms) and their chemical and/or physical changes in time and space.
