geodesic, a.|dʒiːəʊˈdɛsɪk|
[f. geodes-y + -ic. Cf. F. géodésique.]
Of or pertaining to geodesy. geodesic curve, a geodesic line on a curved surface; geodesic dome, a dome built according to the principles of geodetic construction (see quot. 1959) enunciated by the American designer and architect, R. Buckminster Fuller (b. 1895); geodesic line (see quot. 1886). Also n., a geodesic line or curve.
