Vector

Down to earth
from where?
Radius vector
reads in degrees
and it is so hot in here.

Tis a straight line
unless you circle 'round.
Walk with me
where sensational quiet
resonates with sound.

Some are mechanical,
biologically sired.
Word vectors.
if there's such a thing
are greatly admired.

Incensed by direction,
defined by so few.
Vector is contagious
as is learning
something new.
