Chapter 28
Observability Before Geometry

Measurement occurs where systems meet.
At boundaries, information is exchanged between observer and observed.

This chapter examines how boundary interactions generate measurable quantities.

Physical description is fundamentally relational.
Quantities gain meaning only through their relationships with other quantities.

This chapter explores how systems are understood through networks of relations rather than isolated values.

Volume appears to describe the interior of a region.
Yet direct observation occurs only at boundaries and surfaces.

This chapter examines why volumetric structure is inferred rather than directly measured.
