The first postulate is that the equations of dynamics, the motions of
bodies influenced by forces, stay the same in the coordinate systems
that all inertial observers construct for themselves.  The second
postulate extends this to optics.  The goal is for Maxwell's equations
to remain the same for all inertial observers, hence the speed of
light must, when measured by an inertial observer, always be the
same.

Now how does that second postulate make something true and something
false equivalent?  What are the true thing and the false thing that
the second postulate makes equivalent?  And how do you tell which
one is true and which one is false?
