How the Programmer God solved the problem of creating the 4 physical units of mass, length, time and charge (kg, m, s, A) from a dimensionless geometrical object (units = 1). The electron is an example, from this electron object create 2 units (here I use r, v) from units=1 and then define kg, m, s, A in terms of these 2 units with the caveat that no unit can cancel the other, giving us our familiar 4 independent units. However, at the atomic level, 3 (or more) units can combine and cancel. Thus we may create physical units from mathematical structures.
