Hi there Pinto
The
butterfly effect is a concept that states "small causes can have larger effects".
This concept was initially used to theories weather prediction but later the term became a popular metaphor in science writing.
[1]
In
chaos theory, the
butterfly effect is the sensitive dependence on
initial conditions in which a small change in one state of a deterministic
nonlinear system can result in large differences in a later state...
The term itself was coined by
Edward Lorenz for the effect which had been known long before, and is derived from the metaphorical example of the details of a tornado (exact time of formation, exact path taken) being influenced by minor perturbations such as the flapping of the wings of a distant
butterfly several weeks earlier. Lorenz discovered the effect when he observed that runs of his
weather model with initial condition data that was rounded in a seemingly inconsequential manner would fail to reproduce the results of runs with the unrounded initial condition data. A very small change in initial conditions had created a significantly different outcome.
[3]
The idea that small causes may have large effects in general and in weather specifically was used from
Henri Poincaré to
Norbert Wiener.
Edward Lorenz's work placed the concept of
instability of the earth's
atmosphere onto a quantitative base and linked the concept of instability to the properties of large classes of dynamic systems which are undergoing
nonlinear dynamics and
deterministic chaos.
