This question already has an answer here:
As far as I know, Erwin Schrodinger used this thought experiment to show the absurdity of the interpretation of the quantum mechanics.
But many times I encounter on web even famous physicists say things like "When we observe this happens and we do not observe this does not happen ..."
But in the experiment there is a box and a cat inside. What is meant by "observing" here?
Does that mean looking at the box just by opening our eyes? Or does that mean opening the box? What if a blind person opens the box? What interaction causes here to collapse the wave function? What does that to do with "looking"? I don't understand what they mean by "looking" and "observing" in this context...
I'm asking this because some relate this experiment to consciousnesses.
