Most people think that perception is the simple act of opening our eyes and seeing what is out there — a world made up of the clearly observable facts that constitute ‘reality’.  . . . . . . .[however] Neuroscientists and quantum physicists agree that every act of perception also contains an act of conception. The observer and his or her methods of observation affect what is observed. Reality shows up in diverse ways depending on the way of thinking and the way of seeing we employ, and the mental models we use to make sense of what we observe.
