Do you believe that throwing together a concatenation of trite phrases makes you sound more intelligent? If so, I regret to tell you it is not working. In this context what is an equipotential surface? What is the surface measuring/expressing? Why should such equality be a prerequisite for a link between observation and perception? Perception is the very opposite of naked. To associate the two words is to demonstrate you do not understand what perception is. Perception is clothed with many physiological and psychological garments. It is never naked.
