Distance

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:

    I am considered a misanthropist now and then, because I do not socialize with many people. But it’s only my mind that avoids you, my heart is still with you, and seeks the distance so that it can keep on loving you.
    Franz Grillparzer (1791–1872)

    The distance that the dead have gone
    Does not at first appear—
    Their coming back seems possible
    For many an ardent year.
    Emily Dickinson (1830–1886)

    Honor the spirits, but keep your distance from them.
    —Chinese proverb.
