Was thinking about an analogy recently while getting back home from the tram station.

Let us assume you are waiting at a bus stand for a particular bus. Quantum physics is akin to saying: Any given bus can be bus route number 5, 10 or 15 (or any other number) with any of the probabilities ranging from 0 to 1 at any time. It transforms into an exact bus number that arrives next when its probability of being that route number becomes 1. Or vice versa.

But if you are on a particular bus the probability being the same route number is always 1. Or unless you have seen the bus yourself its route number is less than zero but we cant be certain.

Seems like a joke right? I know at the quantum (or very small scale) it maybe true, but can the analogy be used elsewhere in designing systems?
