| social distance | The degree of closeness or acceptance an individual or group feels toward another individual or group. (12 Dec 1998) |
|---|---|
| sociometric distance | Some measurable degree of mutual or social perception, acceptance, and understanding; hypothetically, greater sociometric distance is associated with more inaccuracy in evaluating a relationship (e.g., it is easier to understand and deal with a native than a foreigner). (05 Mar 2000) |
| distance | 1. The space between two objects; the length of a line, especially the shortest line joining two points or things that are separate; measure of separation in place. "Every particle attracts every other with a force . . . Inversely proportioned to the square of the distance." (Sir I. Newton) 2. Remoteness of place; a remote place. "Easily managed from a distance." (W. Irving) "'T is distance lends enchantment to the view." (T. Campbell) "[He] waits at distance till he hears from Cato." (Addison) 3. A space marked out in the last part of a race course. "The horse that ran the whole field out of distance." (L'Estrange) In trotting matches under the rules of the American Association, the distance varies with the conditions of the race, being 80 yards in races of mile heaths, best two in three, and 150 yards in races of two-mile heats. at that distance from the winning post in placed the distance post. If any horse has not reached this distance post before the first horse in that heat has reached the winning post, such horse is distanced, and disqualified for cunning again during that race. 4. Relative space, between troops in ranks, measured from front to rear; contrasted with interval, which is measured from right to left. "Distance between companies in close column is twelve yards." 5. Space between two antagonists in fencing. 6. The part of a picture which contains the representation of those objects which are the farthest away, especially. In a landscape. In a picture, the Middle distance is the central portion between the foreground and the distance or the extreme distance. In a perspective drawing, the Point of distance is the point where the visual rays meet. 7. Ideal disjunction; discrepancy; contrariety. 8. Length or interval of time; period, past or future, between two eras or events. "Ten years' distance between one and the other." (Prior) "The writings of Euclid at the distance of two thousand years." (Playfair) 9. The remoteness or reserve which respect requires; hence, respect; ceremoniousness. "I hope your modesty Will know what distance to the crown is due." (Dryden) "'T is by respect and distance that authority is upheld." (Atterbury) 10. A withholding of intimacy; alienation; coldness; disagreement; variance; restraint; reserve. "Setting them [factions] at distance, or at least distrust amongst themselves." (Bacon) "On the part of Heaven, Now alienated, distance and distaste." (Milton) 11. Remoteness in succession or relation; as, the distance between a descendant and his ancestor. 12. The interval between two notes; as, the distance of a fourth or seventh. Angular distance, the distance made at the eye by lines drawn from the eye to two objects. Lunar distance. See Lunar. <astronomy> North polar distance, the arc on the heavens from a heavenly body to the zenith of the observer. It is the complement of the altitude. To keep one's distance, to stand aloof; to refrain from familiarity. "If a man makes keep my distance, the comfort is he keeps his at the same time." (Swift) Origin: F. Distance, L. Distantia.

| distance ceptor | A nerve mechanism of one of the organs of special sense whereby the subject is brought into relation with his distant environment. (05 Mar 2000) |
| distance of virtual image | <physics> When a simple lens is used as a magnifier for visual observation the eye becomes part of the optical system. A virtual image can be formulated by construction and its apparent distance will vary with the focus of the eye. This will vary among individuals. In a rather arbitrary but standardised assumption, the normal distance for close observation, or reading has been set at 10 inches (250 mm). The optics for the compound microscope have been designed to furnish parallel light from the eyepiece so that the eyes are relaxed for distant viewing. This makes the virtual image lie at infinity. Tests showed that the average observer accommodates somewhat, placing the virtual image rather variably, often about 20 - 25 feet. (05 Aug 1998) |
| distance perception | The act of knowing or the recognition of a distance by recollective thought, or by means of a sensory process which is under the influence of set and of prior experience. (12 Dec 1998) |
| infinite distance | The limit of distant vision, the rays entering the eyes from an object at that point being practically parallel. Synonym: infinity. (05 Mar 2000) |
| interarch distance | The vertical distance between the maxillary and mandibular arches under conditions of vertical dimensions which must be specified, the vertical distance between maxillary and mandibular ridges. Synonym: interalveolar space, interridge distance. (05 Mar 2000) |
| interocclusal distance | The vertical distance between the opposing occlusal surfaces, assuming rest relation unless otherwise designated. Synonym: interocclusal rest space. Synonym: freeway space. (05 Mar 2000) |
| interpupillary distance | <microscopy, ophthalmology> The distance between the centres of the pupils of the eye. The binocular microscope tube must be adjustable for this distance. (05 Aug 1998) |
| interridge distance | The vertical distance between the maxillary and mandibular arches under conditions of vertical dimensions which must be specified, the vertical distance between maxillary and mandibular ridges. Synonym: interalveolar space, interridge distance. (05 Mar 2000) |
| evolutionary distance | <botany> In phylogenetic trees, the sum of the physical distance on a tree separating organisms, this distance is inversely proportional to evolutionary relatedness. (09 Oct 1997) |
| focal distance | The distance from the centre of a lens to its focus. (05 Mar 2000) |
| large interarch distance | A large distance between the maxillary and mandibular arches; may also imply an excessive vertical dimension. Synonym: open bite. (05 Mar 2000) |
| bacteria-free stage of bacterial endocarditis | Endocarditis described prior to the antibiotic era and presumably due to spontaneous healing of the bacterial vegetations. (05 Mar 2000) |
