The butterlfy effect

Acredito firmemente que nada acontece por acaso.

Tudo o que existe será sempre o resultado de um desencadear de eventos contínuo... eterno. É aí que entra a teoria do "Butterfly Effect" (Ou não seria este também um dos meus filmes preferidos de sempre)

"A butterfly's wings might create tiny changes in the atmosphere that may ultimately alter the path of a tornado or delay, accelerate or even prevent the occurrence of a tornado in a certain location. The flapping wing represents a small change in the initial condition of the system, which causes a chain of events leading to large-scale alterations of events (something like the domino effect).

Had the butterfly not flapped its wings, the trajectory of the system might have been vastly different. While the butterfly does not "cause" the tornado in the sense of providing the energy for the tornado, it does "cause" it in the sense that the flap of its wings is an essential part of the initial conditions resulting in a tornado, and without that flap that particular tornado would not have existed."
