Time Scale

A time scale specifies divisions of time.

  • Time standard, a specification of either the rate at which time passes, or points in time, or both
  • Duration (disambiguation), a quantity of time
  • Geological time scale, a scale that divides up the history of Earth into scientifically meaningful periods
  • In astronomy and astrophysics:
    • Dynamical time scale either (in stellar physics) measures the length of time over which changes in one part of a body can be communicated to the rest of that body, or (in celestial mechanics) is a realization of a time-like argument based on a dynamical theory
    • Nuclear time scale, estimates the lifetime of a star based solely on its rate of fuel consumption
    • Thermal time scale, estimates the lifetime of a star once its fuel reserves at its center are used up or if they were to disappear
  • In cosmology and particle physics:
    • Planck time, the time scale beneath which quantum effects are comparable in significance to gravitational effects
  • In mathematics:
    • Time scale calculus, the unification of the theory of difference equations with differential equations
  • In music:
    • rhythm, a temporal pattern of events
    • Time scale (music), divides up music into sections based on the scope

    Another armored animal—scale
    lapping scale with spruce-cone regularity until they
    form the uninterrupted central
    tail-row!
    Marianne Moore (1887–1972)

    The ideal of the self-sufficient American family is a myth, dangerous because most families, especially affluent families, do in fact make use of a range of services to survive. Families needing one or another kind of help are not morally deficient; most families do need assistance at one time or another.
    Joseph Featherstone (20th century)
