@MattDavis,
Quote:We certainly do not know that quantum observations are dependent on an observer.
Perhaps it is better to say that observation affects the event, thereby destroying any hopes of real objectivity. That does seem to be the case in some experiments.
But beyond that, even in everyday life expectations modify what we observe.
What is a good day? Perhaps it is when the sun is hot and the wind is still, and there is no work to be done. But if you are going fishing, a grey sky is better, as it makes it harder for the fish to spot you on the riverbank. If you farm crops, a good day might be when it rains the hardest.
So each of these three, the man on vacation, the fisherman and the farmer looked out the window, each with different expectations. Was it a good day?
