“How do we take a measure of something?” vs “How do we observe something”

THese are synonymous statements, since our observations are narrowly constrained to human scale, and that any observation beyond human scale (perception) requires some form of instrumentation, and some form of scale by which to describe changes in state. There is no difference between instrumentation captured by the eye or that captured by complex scientific machinery other than, while both are often equally fallible, we are born with the first, and must construct the second. But in both cases, external changes in state must be reduced to stimuli that we can contrast and compare.
