Pauli Exclusion Principle and iPod Mini in a juice bar

Recently a number of Leah’s colleagues, including the owner of the juice bar, have acquired iPod minis. However strange things started to happen with all the iPod minis. First one of the worker lost his iPod when the owner’s iPod was playing in the bar. Then today when another worker iPod was playing, the owner left his iPod in the gym and lost it.

To a trained physicist, there is a simple explaination to this. It is the Pauli Exclusion Principle. In short:

In a closed system, no two electrons can occupy the same state.

Obviously Leah’s juice bar is a closed system where no two iPod minis can be in the playing state at the same time. Simple really!
