| has gloss | (noun) an expert who observes and comments on something observer, commentator |
| has gloss | eng: In quantum physics, an observer is an entity that determines an observable (a property of the system state) by a sequence of physical operations. The phenomena of the cosmos require an observer in order to be learned about and understood by us. The observer can take many forms, for example: # A person watching amoeba through a microscope; # A person watching an ocean sunset; # A spacecraft monitoring a distant asteroid (and transmitting data to earth); # A person conducting an experiment in a laboratory. The ideal observer is one who causes no unnecessary perturbations to the system being observed. An observation made by such an observer is called an objective observation. In basic school education of physics and chemistry, we routinely assume that our observations are objective. |
