Distance
Distance is a numerical description of how far apart objects are. In physics or everyday discussion, distance may refer to a physical length, or an estimation based on other criteria (e.g. "two counties over"). In mathematics, a distance function or metric is a generalization of the concept of physical distance. A metric is a function that behaves according to a specific set of rules, and provides a concrete way of describing what it means for elements of some space to be "close to" or "far away from" each other. In most cases, "distance from A to B" is interchangeable with "distance between B and A".

Famous quotes containing the word distance:
“Remember? We sat on a slab of rock.
From this distance in time,
it seems the color
of iris, rotting and turning purpler,
but it was only
the usual gray rock”
—Robert Lowell (1917–1977)
“One sees qualities at a distance and defects at close range.”
—Victor Hugo (1802–1885)
“Small, black, as flies hanging in heat, the Boys,
Until the distance throws them forth, their hum
Bulges to thunder held by calf and thigh.”
—Thom Gunn (b. 1929)
