Re: [Phys-l] Weightless



John,

If I were to hire a contractor to build a pool, I
doubt that the definition of weight would come into
our conversation. I certainly would ask for
references and visit pools they have already built.
Good luck with your quest.

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
*you* fire them, or not?
