Z opens his door to leave, but encounters his pilot friend.  He
tells him that he has called the authorities for directions and is
on his way to Y’s house.  The pilot, who frequently flies overhead,
informs that Z could simply walk out his back door, through his own
and Y’s back yards, and knock on Y’s back door: they are neighbors.
He also says that Z would have seen this on a street map, but Z must
remind him that in spite of taxi drivers, bus routes, ambulances,
firetrucks, and policemen galore, the city has no street map.

   Hopefully, you see something wrong in this story because I try to
make a point:  physics is being done all over the world, it is being
done without a map, there is only one most logical, most elegant way
to map physics, and if you don’t know the map, then you only think
you know physics:

   Using four of the seven base units in the system of units adopted
by all the major metrological laboratories around the world, the
general technique called Geometrical Dimensional Analysis and the
all-in-one map entitled The Outlaw Map of Physics are proof that a
complete and coherent system of quantities can be seen as a vector
space, that “scientific notation” is in many ways outmoded and an
impediment, that logarithm tables can be expanded into multiple
dimensions to produce those selfsame mappings, and that graphical
approaches abandoned in the past can indeed be superior to the
least-squares method of adjusting the experimentally determined
values of the fundamental constants of nature toward a complete
theory of physics.  In fact, by converting to purely logarithmic
notation some of those very values and then structuring them into
one such mapping, count the dots, draw the inference, see the
validation of the technique and realize that acceptance of the
International System of Units means, for example, that:

one (kilogram) = one (coulomb)(second)(tesla)
   = one (farad)(meter^2)(tesla^2)
   = one (weber^2)(farad)(meter^2)
   = one (coulomb^2)(henry)(meter^2)
   = one (ampere^2)(ohm)(second^3)(meter^2)
   = one (coulomb^2)(second^2)((meter^2)(farad))
   = one (farad)(second)(tesla)(volt)  ,

and that the units of the constant of gravitation are

 (meter^3)[(kilogram)(second^2)]   OR
 (farad)(meter)(volt^2)(kilogram^2)   OR
 (meter)[(farad)(second^2)(tesla^2)]   OR
 (farad)(meter)(ohm)(watt)(kilogram^2)   OR
 (meter)(weber^2)[(henry)(kilogram^2)]   OR
 (coulomb^2)(meter)[(farad)(kilogram^2)]   OR
 (ampere^2)(weber^2)[(kilogram^2)(newton)]   OR
 (ohm)(meter^3)[(kilogram)(henry)(second)]   OR
 (coulomb)(meter^3)(tesla)[(kilogram^2)(second)]   OR
 (newton)(meter^2)(kilogram^2).
