Origin of scatter

1125–75; Middle English scatere; compare Dutch schateren to burst out laughing


2 Scatter, dispel, disperse, dissipate imply separating and driving something away so that its original form disappears. To scatter is to separate something tangible into parts at random, and drive these in different directions: The wind scattered leaves all over the lawn. To dispel is to drive away or scatter usually intangible things so that they vanish or cease to exist: Photographs of the race dispelled all doubts as to which horse won. To disperse is usually to cause a compact or organized tangible body to separate or scatter in different directions, to be reassembled if desired: Tear gas dispersed the mob. To dissipate is usually to scatter by dissolving or reducing to small atoms or parts that cannot be brought together again: He dissipated his money and his energy in useless activities.

Scientific definitions for scattering

[ skătər-ĭng ]

The spreading of a stream of particles or a beam of rays, as of light, over a range of directions as a result of collisions with other particles. The sky appears blue due to the tendency of air molecules to scatter blue and violet light more than light of other frequencies. The scattering probabilities and patterns of subatomic particles, accelerated by particle accelerators and aimed at a target, is a major component of experimental particle physics. See also diffusion cross section.
