Among the various theories i have come across in life, the most convincing to me is Chaos Theory. Chaos theory unlike many physical and mathematical theorems deals with real life scenarios in a more closer way. All our life during studying various scientific phenomenon the basic assumption we made was that the subject system is stable or exists in a controlled environment, which is not the case with life. All the events in life whether scientifically anwered or philosophically explainable tends to increase the uniformity of the system rather increase in the total entropy of the system. The events in life depends on a varied number of input parameters and condition some explicit while others are a set of implicit dependent variables which cannot be measured. The basic human nature always visualize a scenario or a condition to be deterministic or as an equation which renders a definite set of solutions. This might be due to the education where we always have a definite answers to all equation. But do all real life examples sums up to a solvable equation? In most of the cases no! but they are atleast deterministic i.e. with a set of input parameters we can predict the outcome of the whole system. This is where Chaos Theory steps in.
A very small change in the input condition results in widely diverging outcomes resulting in the chaotic system which makes future prediction almost impossible. In simple words Deterministic systems are not necesarilly predictable.
In real life we tend to plan assuming the system to be deterministic and in most of the cases even suceed to devise a stable system. The real issue arise when in an assumed stable system some of the basic parameters goes a slight change resulting in highly varied outcome resulting in total chaos. This is a common scenario and can take place from elementary to highly comlicated setups. The degree of chaos depends on the degree of input parameters the system holds which is proportional to the possible leakage in the system. With all the available resources we try to stabilize the system to assure that the damage is minimum. This is not the challenging phase it is the one that follows. The Real Chaos. We usually assume the error in the output are because there is a flaw in system and it needs to be evolved to provide a relatively more stable system to avoid any future mishappening. We plan for stabilizing the system even further introducing more parameters increasing the possibility of leakage with every new input though through another way which will be undiscovered untill it happens one day as the previous one ocurred. We usually tend to forget that the system was stable if the input parameter would have been correct. In most of such scenario major stress is on planning rather than execution.
We can never have answers to how to handle these situation because Chaos theory itself leads to undeterministic nature of the system , the one which cannot be determined.
A very favorite movie of mine 'The Dark Knight' had a monologue between The Joker and Harvey Dent which is quite relevant with the present context:
The Joker: Do I really look like a guy with a plan? You know what I am? I'm a dog chasing cars. I wouldn't know what to do with one if I caught it. You know, I just... do things. The mob has plans, the cops have plans, Gordon's got plans. You know, they're schemers. Schemers trying to control their little worlds. I'm not a schemer. I try to show the schemers how pathetic their attempts to control things really are. So, When I say that you and your girlfriend was nothing personal, you know that I'm telling the truth. It's the schemers that put you where you are. You were a schemer, you had plans, and look where that got you.
I just did what I do best. I took your little plan and I turned it on itself. Look what I did to this city with a few drums of gas and a couple of bullets. Hmmm? You know... You know what I've noticed? Nobody panics when things go "according to plan." Even if the plan is horrifying! If, tomorrow, I tell the press that, like, a gang banger will get shot, or a truckload of soldiers will be blown up, nobody panics, because it's all "part of the plan." But when I say that one little old mayor will die, well then everyone loses their minds!
Introduce a little anarchy. Upset the established order, and everything becomes chaos. I'm an agent of chaos. Oh, and you know the thing about chaos? It's fair!
