| aspect | 1. The act of looking; vision; gaze; glance. "The basilisk killeth by aspect." "His aspect was bent on the ground." (Sir W. Scott) 2. Look, or particular appearance of the face; countenance; mien; air. "Serious in aspect." "[Craggs] with aspect open shall erect his head." (Pope) 3. Appearance to the eye or the mind; look; view. "The aspect of affairs." "The true aspect of a world lying in its rubbish." (T. Burnet) 4. Position or situation with regard to seeing; that position which enables one to look in a particular direction; position in relation to the points of the compass; as, a house has a southern aspect, that is, a position which faces the south. 5. Prospect; outlook. "This town affords a good aspect toward the hill from whence we descended." (Evelyn) 6. <astronomy> The situation of planets or stars with respect to one another, or the angle formed by the rays of light proceeding from them and meeting at the eye; the joint look of planets or stars upon each other or upon the earth. The aspects which two planets can assume are five; sextile, when the planets are 60 deg apart; quartile, or quadrate, when their distance is 90 deg or the quarter of a circle; trine, when the distance is 120 deg; opposition, when the distance is 180 deg, or half a circle; and conjunction, when they are in the same degree. Astrology taught that the aspects of the planets exerted an influence on human affairs, in some situations for good and in others for evil. 7. <astronomy> The influence of the stars for good or evil; as, an ill aspect. "The astrologers call the evil influences of the stars evil aspects. <geometry>" Aspect of a plane, the direction of the plane. Origin: L. Aspectus, fr. Aspicere, aspectum, to look at; ad + spicere, specere, to look, akin to E. Spy. Source: Websters Dictionary (01 Mar 1998) |

| aspect ratio | <radiobiology> In toroidal geometry, the ratio of the major diameter (total width of the torus) to the minor diameter (width of a slice taken through one side of the ring). In inertial-confinement fusion, aspect ratio refers to the ratio of a fuel pellet's radius to its wall thickness. (09 Oct 1997) |
| low aspect ratio | <physics> An aspect ratio for a torus that is small (minor radius is almost as big as major radius). There are many fusion devices which are designed to have a low aspect ratio. Such devices look more like tractor tires than bicycle tires, as toruses go. There are reasons to believe that low aspect ratio devices will offer some advantages for a fusion reactor. Usually, ease of theoretical and/or numerical analysis is not one of these advantages. (16 Mar 1998) |
