Perturbation


Definition:

  • (n.) The act of perturbing, or the state of being perturbed; esp., agitation of mind.
  • (n.) A disturbance in the regular elliptic or other motion of a heavenly body, produced by some force additional to that which causes its regular motion; as, the perturbations of the planets are caused by their attraction on each other.
