The butterfly effect highlights the challenges of predicting complex systems. Because small changes can have a significant impact on the behavior of the system, it is difficult to predict the outcome of complex systems with certainty. This is particularly challenging in fields such as weather forecasting, where small changes in atmospheric conditions can lead to drastically different weather patterns. : The Butterfly Effect index on TV Tropes
The concept was pioneered by meteorologist Edward Lorenz in the 1960s. While running weather simulations, Lorenz entered the number instead of the full 0.506127 . This tiny rounding difference produced a completely different weather forecast, leading Lorenz to realize that the atmosphere is highly sensitive to initial conditions—a property now known as Sensitive Dependence on Initial Conditions (SDIC) . This is particularly challenging in fields such as
