A Paradigm Shift or A Paradise Lost?

Paradigms shifts so often these days...that it leaves many gaping as to when and how it shifted.Very often an old paradigm shifts,when a new one is ready to take its place.

I offer hereby some thumb rules,to identify whether a paradigm shift has occured or not.Then,one or more of the following should have occured:

1.Some one just realised that our current level of understanding on a subject is too weak to justify our future existence .

2.Someone just realised that the current gap between existing understanding and the reality(if there exists any) is embarassingly large to be explained Otherwise.

3.Someone who aspires to win an award or publish a paper has to ensure that on each such occassion the paradigm must shift.

4.The past knowledge was too weak,and we have suddenly woken up to this fact today!So how do we justify our folly!Simple-Just announce to the world that the Paradigm has just shifted.(If you have seen it shifting, can do wonders for your credibility and CV!)

I wonder as to whenever a paradigm shifts,where does it go!If we never hear of the shifted paradigm again,then is it a paradigm shift or a Paradise lost...?
