¶ Point
Index Entry
Points are complex but nondifferentially resolvable by superficial inspection. A star is something you cannot resolve. We call it a point, playing Euler’s game of crossings. One star does not have an insideness and an outsideness. It is a point because you cannot resolve it.
Two remotely crossing trajectories have no insideness nor outsideness but do produce optically observable crossings or fixes which are positionally alterable in respect to a plurality of observation points.
