i think this is to do with the plank constant ( i havnt looked on wiki, and i probably should first), - that is the smallest packet of energy that can be transferred ( waves conatain photons, packets of energy that are transported from one spot to another) therefore since there is a limit on the smallest ammount of energy we can send (like a really dim torch), there is a limit on what we can observe, because on the quantum level, that "light" that we use to see stuff starts to affect what actually happens. ( the dim torch in this example affects the outcome because it gives the particle energy and changes the outcome, and therefore we cannot know what really happens)- this may however be an explanation of schroienders Cat, but i think it is still relevant. However it does not clearly explain the perfect dual pattern that is left upon observation...
- this does not neccersarily have relevance to this but JAYMAX- this is how observation can affect an outcome.. I think i'm breifley (and probably wrongly) explaining the Unsertainty principle.
