fill-t habits
mathematics tradition has assigned
the lower-case t
to designate time
and the greek letter ∆ [delta]
to mean change of or a change in,
while the lower-case v
designates velocity,
and so ∆v/∆t is acceleration,
being a change in velocity
over a change in time.
unsurprisingly,
a change of philosophy over a change in time
is outside the scope of mathematics.
for what it’s worth, though, I am always
more optimistic after a long,
refreshing shower,
reflecting a change of philosophy
over a change in grime.
