Physical science isn't about examining reality. Reality is beyond our grasp. It exists, but we perceive it with imprecision. Since what most people call reality (the physical space we see around us) is in fact an image of reality within our brain, by examining it we're not examining reality but only our perception of it. In other words, physical science is about exploring interaction of human brain (which is capable of self reference) with other physical objects.

Hahaha fucking idiot! Post discarded.
But we do have access to reality through development of precise measuring instruments that do not rely on the human brain. The measurements must of course be interpreted by the brain, but that's what psychophysics is for- the bridge between perceived and objective reality.
If you actually cared, you'd be reading and researching renowned philosophers who've thought of these things way before you did. But I get the feeling the extent of your knowledge is DUDE WEED LMAO. DO YOU EVEN SCIENCE?
Descartes I guess is ok to start with. "Cant know nuthin". Then go through main works of Kuhn and Popper (there are great online resources especially a summary of a lecture given by Popper on an overview of his ideas) and that should be comprehensive enough.
