Primes¶
- Cadence
- A sequence of recurrences (the spaced events). Something happens repeatedly — a beat, a sprint, a report, a contraction, a watch handover, a release — so that there is a series of instances, not a one-off. An inter-recurrence rate (the spacing). A characteristic interval separates consecutive instances, with a reciprocal frequency; this rate — every two weeks, 60 beats per minute, every quarter — is the cadence, the tempo at which the sequence advances. The rate as a first-class parameter (the tunable knob). The spacing is itself a thing one can set, observe, and change — speed it up, slow it down — largely separately from the content of what recurs; tuning the rate is a recognizable intervention. A regularity profile (even or uneven). The spacing may be strictly regular (a metronome, a clockwork release train), approximately regular with drift, or deliberately irregular; how even the beat is is part of the cadence's character and carries operational consequences (predictability, syncability). A matching relation to an external tempo (the load-bearing question). The rate is fast or slow relative to something — the environment's rate of change, the arrival rate of work or information, the bandwidth of a tracker — and the defining question is whether the cadence matches it: fast enough to keep up, slow enough to avoid churn. The possibility of nesting (multi-rate structure). Distinct activities have distinct natural rates, so cadences commonly nest — a fast beat inside a slow one (daily within weekly within quarterly), each timescale served by its own tempo without forcing everything onto one rhythm.
