Foundations of Metrology(1981) [pdf]

Interesting paper. A quick browse shows it to be more of a philosophical overview of the subject focusing on principles and thus accessible to everybody.

Accuracy and Precision (https://en.wikipedia.org/wiki/Accuracy_and_precision) are a good way to approach Metrology (https://en.wikipedia.org/wiki/Metrology). I always found it fascinating that we setup scales which we take for granted as absolute, but which are in fact in reference to some object and thus only relative.
