Definition

Context #1 | Noun

scientific term

Perturbation refers to a small change or disturbance in a system. It is often used in scientific contexts, particularly in physics and metaphysics, to describe how slight variations can affect the behavior of systems. In astronomy, perturbation can refer to changes in the orbits of celestial bodies caused by gravitational influences from other bodies. In mathematics, it can describe changes in values that affect the solutions of equations. Understanding perturbations is critical for predicting the stability and dynamics of complex systems.

Synonyms

disruption, disturbance, fluctuation.
