Nonlinearity

Nonlinearity refers to a relationship where changes in one variable do not result in proportional changes in another. In simpler terms, in a nonlinear system, small changes can lead to large effects, or vice versa, making the outcomes unpredictable. This contrasts with linear systems, where changes are consistent. Nonlinearities are common in nature and science, such as weather patterns, economic markets, and ecosystems, where complex interactions and feedback loops can cause surprising results. Understanding nonlinearity helps us better grasp complex phenomena and manage systems that behave unpredictably.
