Chapter 29
Measurement as Boundary Interaction

Observation must exist before geometry can be defined.
Measurements arise from interactions rather than from assumed spatial structure.

This chapter explores how observability forms the basis from which geometry emerges.

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.
