Hmmm, don't forget though that the population of countries who drive on the
left much exceeds that of the countries who drive on the right !! :-)

It's interesting that you mention this. Over the last several weeks I

Perhaps you should consider us bilingual in terms of units.
Technically inclined (and many other) Anglophones use both English and
SI units with comfort, though we prefer one set for some applications
and the other for others. I wo

I recall in physics class our professor making it quite clear that
'precision' and 'accuracy' are 2 different things! However, all I recall
now is that they were SUPPOSED to be different but not what that difference
was. I did remember where to look for the reference, tho. Here it is:
From St
Speaking of barleycorns reminds me that one can have a lot of fun with
units. My favorite combination has components
atmosphere = 101,325 newton/m^2
yard = 0.9144 m
barn = 1 x 10^(-28) m^2
Combining these we get the
barn yard atmosphere = 9.265158 x 10^(
I think Mike Shaw stated the matter for good using fromerly cited examples
of darts and guns.
Strictly speaking accuracy and precision are sort of independent. If your
mean (average) shot is on the target then you are accurate even if you
never hit the target precisely. Your shots may be off the

Fire 10 shots from a gun at a target.
If the 10 holes in the target are tightly grouped, but near
the outer, you are precise but not accurate
If they are loosely grouped evenly around the bull, you are
accurate, but not precise.
If you can get them tightly grouped around the bull, you
are precise
I am reminded of a particularly relevant cartoon:
An "Old Timer" is looking over the shoulder of a very young man in what is
obviously an engineering drafting room. The caption was:
"I'm not sure about those last eight decimal places, but the first one is

Hello John,
Normally precision of a measurement refers to the repeatability and
accuracy to the absolute "closeness" to the true value. However, after
studying Heisenberg I gave up caring! I remember the distinction
(between precision and accuracy) by using the dart analogy, a good

Yo John!
Old Timers?!
Elderly?.or on old time? or been on the list for a while?or?
My distant history tells me this:
Precision usually means the number of significant figures used to report a
measurement.
Accuracy usually means how close your reported measurement is to the "truth".

"Accurate" and "precise" are relative terms; they are meaningful only in
context. I would think that one could have a ring sundial that was precise
