The Butterfly Effect 2

The “Butterfly Effect,” is a nice thought povoking movie. The title comes from a scientific theory with the same name. The theory is meant to study the predictability, particularly in meteorology. Due to the high complexity of our ecosystem and the large number of inputs (causes), it is nearly impossible to predict the changes in weather (effect) over a long period of time, or at least this is the current state of knowledge. The "Butterfly effect" is the sensitive dependence on initial conditions. It is often ascribed to Lorenz, who mentioned in a paper in 1963 given to the New York Academy of Sciences: “One meteorologist remarked that .... one flap of a seagull’s wings would be enough to alter the course of the weather forever.” The seagull then changed to the more poetic butterfly.

In the movie, the hero had some problems in his life. He then discovers that he can travel back in time, so he does in order to correct things and mistakes that he has done before. Although he does suceed in correcting some mistakes, things donot turn out the way he wanted. Whenever he does correct one thing, he finds that others have gone wrong. At the end he just confesses to his mother "I really screwed things up mum ... I tried so hard to fix everything ... to just make things right, and everytime I do I make it so much worse." ... She tells him "You cannot control everything ... you just have to let it go."
