Density (of a topological space): density character One of the cardinal characteristics of a topological space. The minimal cardinality of a dense set. (Mathematics) [100%] 2023-12-03
Density: Density (symbol: ρ - Greek: rho) is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less ... [100%] 2023-02-03
Density: Density is the amount of mass an object has per unit volume that the object occupies. The most common units of density include kg/L or kg/m in metric units, and lb/gal or lb/ft in imperial units. [100%] 2023-02-18 [Chemical Properties] [Physics]...
Density (polytope): In geometry, the density of a star polyhedron is a generalization of the concept of winding number from two dimensions to higher dimensions, representing the number of windings of the polyhedron around the center of symmetry of the polyhedron.

Density (chemistry): Density (symbol: ρ - Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. (Chemistry) [100%] 2023-06-28
Density: Density (volumetric mass density or specific mass) is the substance's mass per unit of volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used. (Physics) [100%] 2023-11-21 [Density] [Physical quantities]...
Density (computer storage): Density is a measure of the quantity of information bits that can be stored on a given length (linear density) of track, area of the surface (areal density), or in a given volume (volumetric density) of a computer storage medium ...
