Text: "Anisotropy, inhomogeneity, and conservation laws." Illustrates peculiarities associated with two nonlinear Minkowski spacetimes, in which conservation laws may be violated. Spacetime (vacuum), can be made nonlinear by electrostatic scalar potential alone, including an artificial (zero-vector summation of force field vectors) potential field. American Journal of Physics. 51(10), Oct. 1983. p. 919-925.
