Subject: Re: [meteorite-list] Since Scale Cubes are a topic today
Hi, All
I hate to sound a sour note, but these "artifacts" are
for SCALE, not measurement. I think it's wonderful
that folks make them accurate to +/- 0.001 inch or
millimeter, out of materials with low coefficients of
expansion, and so forth, but that is purely an exercise
in personal perfectionism.
<snipped for brevity>
Actualy, I made them to +/- 0.00015 ;-)
But your are right, scale is not a NIST traceable measurement. It's more of
a concept. But still... you can't be too accurate. :-)
