geodesic

IPA: dʒiʌdˈɛsɪk

(geometry) The shortest curve between two points on a specific surface.
(spherical geometry) A segment of a great circle.
(mathematics, sciences) A course allowing the parallel-transport of vectors along a course that causes tangent vectors to remain tangent vectors throughout that course (a straight curve, a line that is straight).

Examples of "geodesic" in Sentences

A geodesic is the shortest path between two points.
Great circle path truest shortest, aka geodesic bulges towards southeast.
The equation of motion is then the so-called geodesic equation, the shortest curve in an arbitrary background, which is not usually - as in flat space, e.g. a lawn - just a straight line:
Ventura Puente and Camelinas (the southern periferico) sit the Convention Center, Planetarium, Teatro Morelos, and the Orquidario --- twin geodesic domes house an outstanding orchid collection.
Also, the precise mathematical form Poincaré chose had to make the Poincaré-line that joins any two points the shortest path between them called a geodesic, just as the usual line is the shortest path between points in Euclidean space.
Gravitons are not a relativity claim, it is an attempt to make gravity into a gauge field theory like electromagnetism and nuclear forces, which use bosons to mediate interactions between particles (and there's no evidence for it) ... general relativity explains gravity as particles following a "geodesic" in the warped geometry of space-time
