'''Oscillation''' is the repetitive variation, typically in [[time]], of some [[measure]] about a central value (often a [[point]] of [[equilibrium]]) or between [[two]] or more different states. Familiar examples include a swinging [[pendulum]] and [http://en.wikipedia.org/wiki/Alternating_current AC] power. The term [[vibration]] is sometimes used more narrowly to mean a [[mechanical]] oscillation but sometimes is used to be synonymous with "oscillation". Oscillations occur not only in [[physical]] systems but also in [[biological]] systems and in human [[society]].
