Douglas Harper's Etymology Dictionary

1650s, from French oscillation, from Latin oscillationem (nominative oscillatio), noun of action from past participle stem of oscillare "to swing," supposed to be from oscillum "little face," literally "little mouth," a mask of open-mouthed Bacchus hung up in vineyards as a charm (the sense evolution would be via the notion of "swing in the breeze"); from PIE *os- "mouth" (see oral).


n. 1 the act of oscillating or the state of being oscillated 2 a regular periodic fluctuation in value about some mean 3 a single such cycle 4 (context mathematics English) (context of a function English) defined for each point x in the domain of the function by infleft{mathrm{diam}(f(U))mid Umathrm{ is a neighborhood of }xright}, and describes the difference (possibly ∞) between the limit superior and limit inferior of the function near that point.

  1. n. the process of oscillating between states

  2. (physics) a regular periodic variation in value about a mean [syn: vibration]

  3. a single complete execution of a periodically repeated phenomenon; "a year constitutes a cycle of the seasons" [syn: cycle]


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. The term vibration is precisely used to describe mechanical oscillation. Familiar examples of oscillation include a swinging pendulum and alternating current power.

Oscillations occur not only in mechanical systems but also in dynamic systems in virtually every area of science: for example the beating human heart, business cycles in economics, predator–prey population cycles in ecology, geothermal geysers in geology, vibrating strings in musical instruments, periodic firing of nerve cells in the brain, and the periodic swelling of Cepheid variable stars in astronomy.

Oscillation (mathematics)

In mathematics, the oscillation of a function or a sequence is a number that quantifies how much a sequence or function varies between its extreme values as it approaches infinity or a point. As is the case with limits there are several definitions that put the intuitive concept into a form suitable for a mathematical treatment: oscillation of a sequence of real numbers, oscillation of a real valued function at a point, and oscillation of a function on an interval (or open set).

Oscillation (cell signaling)

Oscillations are an important type of cell signaling characterized by the periodic change of the system in time. Oscillations can take place in a biological system in a multitude of ways. Positive feedback loops, on their own or in combination with negative feedback are a common feature of oscillating biological systems.

Oscillation (album)

Oscillation is the seventh and final studio album by the Norwegian black/ gothic metal band Trail of Tears. It was released on April 26, 2013 under Massacre Records. The album was recorded at Sound Suite Studio in Marseille, France between September and October 2011, in collaboration with producer Terje Refsnes.

Bjørn Dugstad Rønnow is listed as the band's drummer in the booklet, however, guitarrist Bjørn Erik Næss is credited with having performed the drums on this album.

In those fleeting but recurrent moments of alien lightning he saw himself living, felt and saw inside his brain, and observed there the quickened oscillations of an inexpressibly complicated, delicate, and precious apparatus vibrating with multiple tasks, like a highly sensitive watchworks shielded behind glass because a grain of dust suffices to disturb it.
