The passage around this formula
Before pointing this construction at an interferometer, one methodological trap needs naming. A single measured phase at one fixed loop area cannot, by itself, distinguish m from an unknown additive offset baked into the apparatus — any constant phase shift from an uncalibrated pulse timing, an unaccounted path-length difference, or a stray field looks identical to a rescaling of . The estimator that survives this is a derivative, not a snapshot:

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
