One popular SR book ( Spacetime physics I guess )

comes with the analogy
there was once upon the time a weird city,
where East West distances were measured in metres,
while North south ones in the sacred units.

And that there were 2 groups of surveyors that hated each other.
the day one using compass, the night one using stars.

And that was problem, as "day north" was not "night north"

The data and maps of both groups were not compatible,
as N-S and E-W distances they measured did not fit each other
and maps of the city were rotated.

It was a big problem, until came one surveyor,
that secretly studied in both surveyor schools.

And this guy came with deadly heretic idea
to recalculate the value in sacred units into meters.

Using unified calculations he found interesting invariants ,
values being the same in both systems, and transformations,
comparing data from both groups.

It is funny, until one realizes,
this weird city is Earth
the sacred unit is second.
Not fitting distances are length contraction and time dilation
Not fitting maps are reality in different inertial frames
and the transformation is the Lorentz one.
