What is the relation between classical from quantum vs measurement problem. On one hand they seem to be related on the other they seem to be of different nature. We always see our screens on front of us and not 100 meters away, that we say is classical object although the screen is a quantum object in the end and it exists even when we are not looking at it . But the measurement of quantum systems says it only takes reality when "measured". I am confused when people discuss wavefunction collapse in regard as to which problem is actually being addressed and the relation. Edit by mentor. You cannot bump a thread in less than 24 hours, so your posts have been merged. Please read the rules. It's amazing that after all of this time here you have never bothered to read the rules. Since I am not getting any response let me ask a simpler question. Are classical objects considered to be a collapsed wavefunction of the system or the subsystems or what?.
