SMELL 101

How smell works

Smell begins with molecules and biology, but the human experience of smell also involves attention, context, memory and language.

01

From air to perception

Odor-active molecules can reach receptors in the nose, but the experience that follows is not just a chemical label. The brain interprets patterns together with context and prior experience.

02

Why one smell can feel different

Intensity, temperature, humidity, surrounding smells, expectation and personal history can all change what someone notices or how they describe it.

03

Why SmellBook uses layers

A useful public smell identity needs more than one field. Source, descriptors, context, feeling, culture and evidence status should remain distinguishable.
