  • The researchers conducted a study to understand how perturbative forces influence the behavior of particles in a collider.

Examples

  • Scientists often use perturbative methods to analyze the stability of complex systems in mathematics.

  • In physics, small fluctuations in energy levels can lead to a perturbative effect on the overall stability of the system.

  • So that's this perturbative serious expansion that you would use here.

  • You've written that a big hole in string theory has been its perturbative definition.

  • So it does describe the physics that I want, at least in this perturbative sense of the epsilon expansion.

  • Presumably, the amputees perceived shock as merely a perturbative impact, even though shock consisted of three elements: amplitude, frequency, and rate of damping.

Morphology

perturbative = perturb (semi-transparent) = perturb + ative

Formally derived from 'perturb' + '-ative' and the sense 'causing or relating to disturbance' follows from 'perturb', but the vocabulary is formal and may not be obvious to a general B1 learner.

Etymology

Perturbative comes from the Latin perturbare, made of per- 'completely' and turbare 'to disturb'. Think of a rock thrown into a calm pond that makes waves and confusion. So, something perturbative is one that causes disturbance or instability.
