A sort of gear was discovered,
a way of warping space so that
the passage of time was altered.
Moments could be slowed down, stopped,
and gently rocked backwards.
They used this phenomenon as the
center of a device called the Differential
The differential was conceived as
the final, ultimate solution
of keeping time. Using a series
of interlocking warped space gears,
any moment of time could be
forced into regression until it
reached the theoretical limit of the
subdivision of time, the so-called instant.
The differential operated such that
intervals of time were measured
using the theorems of calculus
in an experimental subdivision of each
moment into a limit approaching infinity number
of interval-less instants. Unfortunately
there was no way to display the
results of this operation. The
differential was designed only to
keep time. Not to tell it.
