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:
“You say I’m small? I certainly can relate, although it is a matter of perspective. The distance is deceptive, my friend, you stand too low.”
—Franz Grillparzer (1791–1872)
“It is painful to recall a past intensity, to estimate your distance from the Belsen heap, to make your peace with numbers. Just to get up each morning is to make a kind of peace.”
—Leonard Cohen (b. 1934)
“Let me approach at least, and touch thy hand.
[Samson:] Not for thy life, lest fierce remembrance wake
My sudden rage to tear thee joint by joint.
At distance I forgive thee, go with that;
Bewail thy falsehood, and the pious works
It hath brought forth to make thee memorable
Among illustrious women, faithful wives:
Cherish thy hast’n’d widowhood with the gold
Of Matrimonial treason: so farewel.”
—John Milton (1608–1674)
