Dense

Density and dense usually refer to a measure of how much of some entity is within a fixed amount of other space. Types of density include:

In physics:
 * Density, mass per volume
 * Area density, mass over a (two-dimensional) area
 * Linear density, mass over a (one-dimensional) line
 * Planck density, Planck mass per Planck length
 * Specific gravity, a dimensionless ratio based on the density of a substance to the density of water
 * Relative density, a measure of density in comparison to the density of something else
 * Vapour density, a relative density used for gases
 * Current density, the ratio of electric current to area
 * Charge density, the electric charge per volume
 * Energy density, potential energy per unit volume or mass, depending on context
 * Force density, force per unit volume
 * Information density, the amount of information compared to many units
 * Optical density, the absorbance of an element

In mathematics:
 * Dense set and nowhere dense set in topology
 * Schnirelmann density in number theory
 * Natural density (also called asymptotic density) in number theory
 * Lebesgue density in measure theory
 * Probability density function, a function which maps probabilities across the real line and whose integral is 1
 * Density estimation is the construction of an estimate of a probability density function
 * Kernel density estimation, used in statistics to estimate a probability density function of a random variable
 * Tensor density in differential geometry
 * Density in graph theory, the fraction of possible edges that exist in a graph
 * Dense order in order theory
 * Dense-in-itself, in geometry, is a set that contains no isolated points
 * In forcing (mathematics), a subset D of a forcing notion (P, ≤ ) is called dense in P if for any p in P there is d in D with d≤p

In other scientific fields:
 * Population density, population per unit area
 * Computer storage density, bits (how computers store information) over an amount of area or volume

Density can also refer to:
 * Spiritual density, states of being for various planes of existence
