The Parrot's Theorems - An invariance classification of operational measurement reports

An observer who cannot see a system directly -- only a dial and a reading -- reports numbers, but not every number is a property of the system. We sort operational readouts into three recurring invariance classes: integer counts of exposed degrees of freedom, reparametrization-in...
