| brachystochrone | <mathematics> A curve, in which a body, starting from a given point, and descending solely by the force of gravity, will reach another given point in a shorter time than it could by any other path. This curve of quickest descent, as it is sometimes called, is, in a vacuum, the same as the cycloid. Origin: Incorrect for brachistochrone, fr. Gr. Shortest (superl. Of short) + time: cf. F. Brachistochrone. Source: Websters Dictionary (01 Mar 1998) |
