Nonlinear dynamics is a field of study within mathematics and physics that focuses on the behavior of systems that are not easily described by linear equations. In nonlinear systems, small changes in initial conditions can lead to dramatically different outcomes, making them inherently unpredictable. Nonlinear dynamics examines the complex behavior exhibited by these systems, including chaos, bifurcations, and strange attractors. Researchers in this field use mathematical models and computer simulations to study the dynamics of nonlinear systems and understand their behavior. Applications of nonlinear dynamics can be found in various fields such as biology, economics, engineering, and meteorology.
