    en.wikipedia.org/wiki/Kappa

    Variant kappa Greek word καί written with a handwritten variant of kappa, from the Byzantine period. Kappa (/ ˈ k æ p ə /; [1] uppercase Κ, lowercase κ or cursive ϰ; Greek: κάππα, káppa) is the tenth letter of the Greek alphabet, representing the voiceless velar plosive IPA: sound in Ancient and Modern Greek.

  5. Heat capacity ratio - Wikipedia

    en.wikipedia.org/wiki/Heat_capacity_ratio

    In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (C P) to heat capacity at constant volume (C V).

  6. Relative permittivity - Wikipedia

    en.wikipedia.org/wiki/Relative_permittivity

    Relative permittivity is typically denoted as ε r (ω) (sometimes κ, lowercase kappa) and is defined as = (), where ε(ω) is the complex frequency-dependent permittivity of the material, and ε 0 is the vacuum permittivity.

  7. Chi (letter) - Wikipedia

    en.wikipedia.org/wiki/Chi_(letter)

    In mechanical engineering, chi is used as a symbol for the reduction factor of relevant buckling loads in the EN 1993, a European Standard for the design of steel structures. In graph theory, a lowercase chi is used to represent a graph's chromatic number. In analytic number theory, chi is used for the Dirichlet character.

    Latin and Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.

  9. Kappa–mechanism - Wikipedia

    en.wikipedia.org/wiki/Kappa–mechanism

    The kappa opacity mechanism is the driving mechanism behind the changes in luminosity of many types of pulsating variable stars. The term Eddington valve has been used for this mechanism, but this is increasingly obsolete. [1] Here, the Greek letter kappa (κ) is used to indicate the radiative opacity at any particular depth of the stellar ...
