Chaos theory is a branch of physics and math that studies complex systems whose behavior is highly sensitive to initial conditions—a phenomenon often referred to as the "butterfly effect." In chaotic systems, tiny differences in starting points can lead to vastly different outcomes, making long-term prediction nearly impossible despite the system being deterministic. Chaos theory applies to systems such as weather, climate, ecosystems, the stock market, and even brain activity. These systems are nonlinear, meaning outputs are not directly proportional to inputs, and small changes can cause disproportionately large effects. This unpredictability arises not from randomness, but from the system's inherent complexity and feedback loops. One of the key insights of chaos theory is that chaos can arise in simple systems with just a few rules or variables. Chaos theory has reshaped our understanding of determinism and predictability, revealing that even well-defined systems can behave in ways
