In chaotic systems, such as weather, it is very hard to predict future unless you had a super computer and very accurate readings at a single moment (initial conditions). If those initial conditions had a very small error (really very small) then it is magnified enormously that the future predicted is totally different than the actual one. So this is what is called the butterfly effect. A very small and insignificant change such as the flab of a butterfly wing changes the future totally.
I remember one day at a French class in 10th grader that I was telling Saad this thing. Not the same way but I told him that if you are about to pass through the linguistics’ lab door, where we used to take French, there can be two conditions just for the sack of simplicity, either you hesitate before going out or you go without thinking. If you went out with out thinking lets say that you continued to the teacher room, your future will take route “a” lets say, whatever this route was. If you hesitated let’s say and it took you 1 second before stepping out, then you will hit a person when you go outside. Am trying to keep it simple so am just saying that this or that can happen, while it can be more complicated. So after you hit that person you forgot what you wanted to do before the collusion. You continued your way to the cafeteria where you found Obaid and Dea’a and your future took route “b”, goodness I do not wanna even think about this route ;).
So this thing was one of my concerns for a long time, because this means redoing your past if you have the chance to will be a trade off. You might get depressed when you remember a thing that happened in the past, but this thing is what made your life the way it is now.
Btw there will be a movie this week at mbc2 about this thing named ‘The butterfly effect’. Did anyone watch it before? The end of the movie is not the original end. The original end is a tragedy, but very impressive.
