[MD] 2 + 2 = 5?

[Ron Kulp]

Kevin,
Being in a field of precision and accuracy myself I find it fascinating,
I came to the idea while
Helping my daughter with her math homework, they were working on
rounding. I round every day,
Never really thinking about it, there are standards of rounding so
everyone is allowing for the 
rounding error in the same direction, I made the remark to her that in
this way of using numbers
2+2 can = 5 , 1+1=3 for that matter, file this one, be a great science
project. Then I started 
Thinking about it. Surveyors take their job seriously, mathmatically
locating and labeling 
"existing" features, I spent 3 yrs out in the field doing this, this is
difficult work
"existing" features seldom cooperate and some things are not in the
descripter code.
Finding the rounding error and averaging it is how the best precision is
achieved. But
It is not absolute it is averaged. An average is a mathmatical "value"
of absolute or true.

This is how I arrived at "oneness" can not be absolute, oneness lies in
"value"
Eternal averaging....change
Or as you stated, interaction. Once you see that oneness can not be
absolute you realize
There can be no absolute beginning nor end for that matter but a
dynamic.  A Dynamic value.
The tao is "the dynamic value" Dynamic quality and that's why Pirsig
said theres lies madness.
So the metaphysics of the dynamic value may be a better choice of
terminology...

So 2+2=5 is a sort of  mathmatical tao 

Hmmmmmm,
Seems Case was right all along, it's all about the value of your
#2...heh,

"rounding error" as cause???  As in it caused the world to shake, causes
Chinese butterflies to flap their wings and causes irrational numbers to
transcend???
 
Stay too long in the world of metaphors and backasswards begins to look
normal.

See what I mean?
 
Seriously, Ron (hello Ron) is right, to a point, when he says, "There's
no such thing as absolute precision."  The point is context.  Whether
it's measuring property lines with a laser range finder or the diameter
of a bone screws with a micrometer the measurement's precision is itself
a measure of the repeatability and reproducibility of the measuring
process.  Repeatability is a measure of the variation among several
measurements obtained by the same person using the same measuring device
to measure the same thing.
Reproducibility is a measure of the variation among several measurements
obtained from different persons using the same measuring device to
measure the same thing.  Several nearly identical measurements obtained
from several people would describe a highly precise measuring process.
 
The point is there is no context that does not involve variation.
 
Static patterns?  We don't need no stinkin' SPOVs.
