The Geometer as Conjuror
The Status of Force in NewtonCartan Theory

Abstract: I consider epistemological implications
of Cartan's generally covariant theory of Newtonian gravity, which
allows one to choose between a flat geometry plus force, and a curved
geometry into which force has been ‘absorbed’. Can the
geometer conjure up force at the stroke of a pen? Is force an empty
mathematical fiction?
