This is backwards cause-effect

Mathematical axioms are derived from sensory experience in this physical reality

The math is actually river-like

Rivers form fractal shapes just like how Iterated Function Systems[1] and L-systems[2] form: by simple branching, carried out at varying levels of scale. A gentle reminder that fractals are nature's favorite building block.
