| tautochrone | <mathematics> A curved line, such that a heavy body, descending along it by the action of gravity, will always arrive at the lowest point in the same time, wherever in the curve it may begin to fall; as, an inverted cycloid with its base horizontal is a tautochrone. Origin: Gr, for the same + time: cf. F. Tautochrone. Source: Websters Dictionary (01 Mar 1998) |
