1) Please name one engineer who was ever silly enough to
use the formula
- G M
"g_vector" = -------- r_vector (???)
r^3

for any precision terrestrial engineering application.

2) Suppose you hired contractors to install an in-ground
swimming pool in your back yard. Suppose they wanted to
build it so that the rim was "horizontal" in the sense of
being perpendicular to the "g_vector" defined above. Would
