The numbers behind the nose — seven molecules, quantified

Each row is a dimension of identity. The threshold — how little must exist before it is perceived — is the most intimate metric: a measure of what the body already knows how to find.

COMPOUND IDENTITY

Your olfactory signature, rendered as waveform data

Each waveform is one molecule. Amplitude reflects olfactory potency — how little the nose needs to perceive it. The lowest threshold leaves the deepest mark. Together, these seven signatures compose a self-portrait that predates language.

WHAT CANNOT
BE CONTAINED

A perfume bottle holds identity in suspension — until the pressure of what is inside exceeds what the vessel was designed to hold.
