Read this. Take a second to stop looking at all the pretty pictures on your dash or reblogging all of the fun memes and read about what is happening. Just read it. People need to know what is happening before they can help, and the more people that know the better. There could be something you could do, or there could be something someone you know could do. Maybe one of your followers wants to help, or knows someone who can help. Just read it, and please reblog posts regarding Libya. Ignoring it because you don’t want to hear about something so sad won’t make it go away. Please.
The butterfly effect is a metaphor that encapsulates the concept of sensitive dependence on initial conditions in chaos theory; namely, a small change at one place in a complex system can have large effects elsewhere.
The phrase refers to the idea that 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. 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.
