Nonlinear oscillators

Nonlinear oscillators are systems that move back and forth in a way that isn’t simply proportional to their current state. Unlike linear oscillators, like a basic pendulum, their behavior can be more complex, with movements that change unpredictably at times, creating intricate patterns such as chaos or multiple rhythms. This non-proportionality often arises from the system's internal properties, leading to rich and diverse dynamics. Examples include certain mechanical devices, electrical circuits, or biological rhythms that don’t follow straightforward, predictable patterns, highlighting the complex behavior that can emerge from nonlinear interactions.
