The dimensional analysis and attachment to geometry and arithmetic usually is about the only "physical" there is. (Geometry and arithmetic and the objects of analysis and so on.) Things like "negative time" and "anti-deSitter space" are unphysical, as are the non-real parts of complex analysis, usually, though for example if you consider the Cartanian as essentially different from the Gaussian-Eulerian, complex analysis, then the Majorana spinor makes an example of a detectable observable, though, one might aver that that's its real part, in the hypercomplex. The Gaussian-Eulerian deserves a real break-down of a deconstructive account about Euler's identity and Gauss' integral and so on, about the regular singular points of the hyper-geometric and so on (0, 1, infinity). That wave mechanics have super-classical real parts is a thing. If it's a geodesy, it's a geometry. The "coordinate-free" are just "hidden coordinates", patched together piece-wise.
