According to it a particle may exist in one or more states or place at a same time. But if we try to measure it, it just changes the behaviour . Here by just observing the wave function collapses..
Well,there is a simple experiment to validate Correspondence Principle. It says that individual entity uncertainty occurs, but for a group it ceases to the average of all. For example if we throw a dice, there will we six possibilities, i.e the outcome maybe 1, 3 or 6 and there no one can bet.. But if we throw a dice million of times then you can confidently say that the average outcome will be (1+2+3+4+5+6)/6 i.e 3.5 .
The experiment is computerized.. There’s a real time random number generator (a exe application) which prompts a user to press a key, and then it will generate a random number between 1 and 999. There’s another application who finds the average of all. Now by correspondence principle the aggregate outcome should be the average of all i.e (1+2+3+…+999)/999 = 500 . And it happens,,,
I’ve experimented for 217 iteration and the average is 485.5, which is very near to 500.
Well, still more iteration must be done to see does it really converges to the average or not..
