Again, the measurement itself is just a number (or set of numbers)
It's not even that. Assuming a digital voltmeter, it's just e.g. the
two leftmost segments of a 7 segment LCD display not reflecting light.
Numbers don't exist in the sense in which a voltmeter exists. It's
part of the conceptual framework of the user to interpret the LCD
display as showing "1". Another part of that framework is to interpret
that as "1 Volt". I fail to see how you can separate these two parts
from one another.
- by itself, it cannot be wrong.
A number is a semantic entity. As such, it can be wrong.
It is an important point in sciences: just because the measurement
doesn’t match what you expected, that does not make the measurement
wrong. Usually it just means that there is something you failed to
account for in the theory that predicted the values. If we threw
away all results that didn’t match expectations, much of our
scientific discovery would never happen.
True. But I would guess that most of the more important discoveries
came from voltmeters that showed unexpected results although they were
working correctly, than from those that showed unexpected results
because they were broken. :-)
