• According to Einstein's principle of equivalence, the proper measure of the gravitational field is provided, not by the acceleration of one neutral test particle, but by the relative acceleration of two nearby test particles. This relative acceleration is described by the equation of geodesic deviation. In this equation the Riemann curvature tensor provides the mathematical measure for the physically relevant feature of the gravitational field, the "tide-producing force". It is shown that the electromagnetic field allows of description by way of a "higher order equation of geodesic deviation" based on higher differences between the positions of a whole group of nearby neutral test particles. In this sense the gravitational and electromagnetic fields can be regarded as describing non-local features of space. Space locally always has Lorentz geometry, no matter how strong the fields may be.
