It is ok for physics to distinguish between me and a rock out somewhere on the surface of mars ? Who am I but a bag of chemicals ? Why would my action of observing be of any significance ? Why should the moon be "paged-in"/from-into-existence when I "observe" it and other times it is allowed to go for a walk(even if it is only a change in probability of finding the moon). Why is my observing the moon any different from a "rock observing the moon" ? I am a computer engineer, and recently started reading QM. I was displeased with what I inferred. Can somebody confirm this understanding that I have come about QM?
