the.com/perimeter
the boundary that knows exactly where you end and chaos begins.
means The continuous line or path that forms the outer boundary of a two-dimensional shape or enclosed area, or the total length of that boundary.
from From Greek 'perimetros,' a tidy joining of 'peri-' (around) and 'metron' (measure) — literally 'the measure around.' It came into English through Latin, carrying that geometric sense of pacing the edge of a thing and tallying every step. The same 'metron' lurks in 'thermometer,' 'diameter,' and 'symmetry,' all members of the great measuring family.
