  • (Wikipedia, 2009) ⇒
    • A constant in mathematics is an amount that does not change, over time or otherwise: it is a fixed value. In most fields of discourse the term is an antonym of "variable", but in mathematical parlance a mathematical variable may sometimes also be called a constant.
    • More particularly, the term constant has several uses:
  • In mathematics and computer science:
  • In physics and chemistry:
    • Physical constant, a physical quantity that is generally believed to be both universal in nature and constant in time, such as [math]\displaystyle{ c }[/math], the speed of light, or [math]\displaystyle{ h }[/math], the Planck constant.
    • Cosmological constant, usually denoted by Λ, a parameter modifying the original equations of the theory of general relativity, introduced by Einstein and important for determining the ultimate fate of the universe as predicted by the theory
    • Time constant, usually denoted by τ, a value characterizing the frequency response of a first-order, linear time-invariant system
    • Reaction rate constant, often denoted [math]\displaystyle{ k }[/math] or λ, a value characterizing the speed of a chemical reaction
