When the distance between the specimen and light source, and the intensity of the light source are fixed, the amount of the light received by the crack is reduced by the

inverse-square law [11-13], and the theoretical value can be obtained by (1).

The time-retarded version for Newton's

inverse-square law becomes

We know that if we go slowly it takes longer to get there; we know that when we fall down, the farther we fall the more it hurts; we know that the faster the motion of something that hits us, and the bigger it is, the more it hurts; we know that the farther we are from our Mommy, the fainter are her cries, though we never heard of the

inverse-square law or anything much else in the language.

Hooke is known as the man who dared challenge Newton as discoverer of the

inverse-square law of gravitational attraction.

If Hooke is remembered at all, it's for actions during his prime years, when he became a controversial figure for publicly claiming credit for Isaac Newton's

inverse-square law of gravity.

Another supporting argument is that the small and stealthy UCAV is survivable enough to get closer to the threat emitter, allowing the

inverse-square law to work to an advantage.

Recognition of the laws of motion and of the

inverse-square law of universal gravitation were strongly linked with each other, since motions of planets and comets provide the clearest test for any theory of motion.

An interesting example is the borrowing of Newton's

inverse-square law by international trade theorists in economics.

If it is as fast, one would expect

inverse-square law attenuation of the psi signal.
