Great! Critical question: What constitutes a single instrument, and
where do we draw a line to tools? I'd argue that one measurement
instrument should be able to yield a quantitative result, and be a sort
of "black box" integrated device, such as the sequencing machines.
Question: yardsticks are "passive". Are they still instruments, even
though the human eye is the instrument? I think they are a different
category of calibrated objects for comparing, such as color charts etc.
Cheers,
Martin

Dear All,
Just to give you a picture of the diversity and complexity we discuss.
Probably the high-end in complexity is a DNA - taxonomic distance
measurement, a procedure, even though straightforward and
deterministic,
as I understand, with an great number of steps, a series of
instruments
subsequently used and possible errors in each one.
Interesting also a LIPS / Raman analysis of painting colorants, which
uses multiple instruments until the final result, not reliably
quantitative and including assumptions about a limited set of
possible
colorants that might be wrong.
As the most simple ones we may have yard sticks, but the most
exotic in
simplicity I can think of are pyrometric cones. They are used
worldwide
to monitor ceramic firings in industrial kilns, pottery kilns, for a
one-time measurement of the maximum temperature reached by firing a
kiln. They are calibrated to one temperature only, but normally
destroyed by the measurement.
What is "one instrument", and are pyrometric cones and yardsticks
instruments? What about body parts (ells, feet)
Best
