density order
1Density (disambiguation) — Density and dense usually refer to a measure of how much of some entity is within a fixed amount of space. Types of density include: In physics, density of mass: Density, mass per volume Area density or surface density, mass over a (two… …
2Density 21.5 — is a piece of music for solo flute written by Edgard Varèse in 1936 and revised in 1946. The piece was composed at the request of Georges Barrère for the premiere of his platinum flute, the density of platinum being close to 21.5 grammes per… …
3Order statistic — Probability distributions for the n = 5 order statistics of an exponential distribution with θ = 3 In statistics, the kth order statistic of a statistical sample is equal to its kth smallest value. Together with rank statistics, order statistics… …

6Density wave theory — Image of spiral galaxy M81 combining data from the Hubble, Spitzer, and GALEX space telescopes. Density wave theory or the Lin Shu density wave theory is a theory proposed by C.C. Lin and Frank Shu in the mid 1960s to explain spiral arm structure …
7Order of magnitude — An order of magnitude is the class of scale or magnitude of any amount, where each class contains values of a fixed ratio to the class preceding it. In its most common usage, the amount being scaled is 10 and the scale is the (base 10) exponent… …
8Density — This article is about mass density. For other uses, see Density (disambiguation). The mass density or density of a material is defined as its mass per unit volume. The symbol most often used for density is ρ (the Greek letter rho). In some cases… …
9Density contrast — The Density Contrast is a parameter used in galaxy formation to indicate where there are local enhancements in matter density. It is believed that after inflation, although the universe was mostly uniform, some regions were slightly denser than… …
