Method of image charges — The method of image charges (also known as the method of images and method of mirror charges) is a basic problem solving tool in electrostatics. The name originates from the replacement of certain elements in the original layout with imaginary… … Wikipedia
Density of air — The density of air, ρ (Greek: rho) (air density), is the mass per unit volume of Earth s atmosphere, and is a useful value in aeronautics and other sciences. Air density decreases with increasing altitude, as does air pressure. It also changes… … Wikipedia
Density — 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… … Wikipedia
Density matrix — Mixed state redirects here. For the psychiatric condition, see Mixed state (psychiatry). In quantum mechanics, a density matrix is a self adjoint (or Hermitian) positive semidefinite matrix (possibly infinite dimensional) of trace one, that… … Wikipedia
Constant linear velocity — Comparison of several forms of disk storage showing tracks (not to scale); green denotes start and red denotes end. * Some CD R(W) and DVD R(W)/DVD+R(W) recorders operate in ZCLV, CAA or CAV modes. In optical storage, constant linear velocity… … Wikipedia
Planck constant — Planck s relation redirects here. For the law governing black body radiation, see Planck s law. Values of h Units 6.62606957(29)×10−34 J·s[1] 4.135 … Wikipedia
Avogadro constant — The Avogadro constant (symbols: L , N A), also called Avogadro s number, is the number of elementary entities (usually atoms or molecules) in one mole, that is (from the definition of the mole) the number of atoms in exactly 12 grams of carbon 12 … Wikipedia
Marsaglia polar method — The polar method (attributed to George Marsaglia, 1964[1]) is a pseudo random number sampling method for generating a pair of independent standard normal random variables. While it is superior to the Box–Muller transform[citation needed], the… … Wikipedia
Dumas method of molecular weight determination — The Dumas method of molecular weight determination was historically a procedure used to determine the molecular weight of an unknown substance. The Dumas method is appropriate to determine the molecular weights of volatile organic substances that … Wikipedia
Relative density — Relative density, sometimes called specific density, is the ratio of the density of a substance to the density of a given reference material. If a substance s relative density is less than one then it is less dense than the reference; if greater… … Wikipedia
Energy density — For energy density in the sense of energy per unit mass, see specific energy. For energy density of foods, see specific energy. Energy density is a term used for the amount of energy stored in a given system or region of space per unit volume.… … Wikipedia
