Parallax is the apparent shift in position of an object when observed from different vantage points, formalized as a measurement technique using triangulation. Parameters: (1) baseline — the separation between observation points; (2) angular displacement — the measurable difference in the object's apparent position; (3) triangulation — the geometric method converting angular shift into distance. The concept extends beyond astronomy into cognitive and social domains, where it denotes how conclusions, interpretations, or judgments shift when the frame of reference changes. Persistence: mathematical formalization, scientific instruments (sextants, parallax bars), and cross-disciplinary metaphorical usage in philosophy, psychology, and rhetoric. [formal: parallax | substrate: mind | horizon: a moment | explicit: yes | epoch: 0.10]

Definition
Why it is in scope
The human-made concept of apparent positional shift when an object is observed from different vantage points, formalized as a measurement technique and extended metaphorically across disciplines to denote how understanding changes with perspective. It is the map of perspective-dependent observation — the framework humans built to quantify, reason about, and apply viewpoint-dependent displacement.

Parallax is the apparent displacement of an object when viewed from different angles. Removal test (Law 8): remove perspective and parallax cannot operate — there is no displacement without different viewpoints to observe it from. This is a real operating dependency, not just sayability. Parallax literally requires perspective to function.
- cmr9uz3vv00elhcxfruyltnd4SERVES →
Parallax is a measurement technique whose designed purpose is to enable measurement of distance through apparent displacement. SERVES captures teleology — the technique exists for the sake of measurement.
