Having a breezy Sunday afternoon in the middle of a pandemic lockdown is not what I would have envisioned a year ago when we precipitously – and quite unwillingly I might add -reclaimed terra firma upon return from the shores of Longboat Key on the Gulf of Mexico. Indeed I wonder that I mightn’t have looked so far ahead for any purpose. The postulation is therefore moot. Yet it illustrates the circumference of the compass that is one’s fortune.
In geometry, the circumference (from Latin circumferens, meaning “carrying around”) is the perimeter of a circle or ellipse. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment. More generally, the perimeter is the curve length around any closed figure. Circumference may also refer to the circle itself, that is, the locus corresponding to the edge of a disk.
