1 Introduction Newton's inverse square law of gravity, when expressed in terms of an acceleration field g(r, t), has the differential form: [nabla] x g = -4[pi]G[rho], [nabla] x g = 0 (1) where G is the gravitational constant and [rho] is the real matter density.

The statement at the bottom of the first column on Page 15, "Using the inverse square law, intensity is reduced by one quarter every time the distance is doubled," is not correct.

In effect, the rate at which oil mass is lost from an ink decays according to an approximate inverse square law with time.

Lotka's Law Lotka (1926) proposed an inverse square law relating authors of scientific articles to the number of articles written by each author.

Scientists raised the idea of a fifth force in 1986 after finding hints that the gravity inside an Australian mine shaft did not follow Newton's inverse square law.

2] (5) which is Newton's Inverse Square Law of 1687 [9], but with an effective mass M(1 + [alpha]/2 + .

At stake is the accuracy of Newton's inverse square law of gravity, which holds that the gravitational attraction between two bodies is proportional to one over the square of the distance separating the bodies.

Nevertheless those reports motivated the Greenland, Nevada and Ocean experiments, as well as above-ground tower experiments [19], all with the assumption that the non-Newtonian effects were being caused by a modification to Newton's inverse square law by an additional short-range force--which also involved the notion of a possible "5th-force" [21].
