the.com/winnowing fan
The original algorithm for separating wheat from chaff: throw it in the air and let physics judge.
means A broad, shallow basket or tool used to toss harvested grain into the air so wind carries off the lighter chaff while the heavier kernels fall back down.
from Comes from Old English 'windwian,' meaning to winnow or fan grain, itself related to 'wind' — the moving air that did the actual work. The 'fan' part is literal: these tools were often flat, fan-shaped or basket-like implements, swung or shaken to generate a breeze. The practice is ancient, showing up in classical and biblical texts alike, where winnowing fans even became symbols of judgment — separating the worthy grain from the worthless husk, a metaphor that outlasted the farm tool itself.
