arrival time · until-wall
Ask PrometheusThe time until drift moves a parameter to a wall of its window, at the current rate.
Arrival time (noun) means: The time until drift moves a parameter to a wall of its window, at the current rate. It emerges from drift, parameter, wall, window: Distance to a wall divided by the rate of drift toward it gives a time, and that time, not the distance, is what decides whether any correction can still land. A near wall approached slowly can leave more time than a far wall approached fast. In the EmergenceLexicon it sits at computed level 12, chaining down to the four foundations (space, time, energy, pattern).
Examples
- Before a hurricane's landfall the US National Hurricane Center publishes the earliest reasonable arrival time of tropical-storm-force winds, telling each stretch of coast how long it has left to prepare. meteorology

- distance converted into time
- the quantity a correction must beat
- a wall that is approaching rather than standing
