In the original sense, a geodesic was the shortest route between two points on the Earth's surface. For a spherical Earth, it is a segment of a great circle (see also great-circle distance).

4 days ago · A geodesic is a locally length-minimizing curve. Equivalently, it is a path that a particle which is not accelerating would follow. In the plane, the geodesics are straight lines. …

Joseph Howlett, Quanta Magazine, 3 Mar. 2025 In fact, for curved spaces, the shortest path is what’s known as a geodesic: the generalization of a straight, flat line to a curved space.

Feb 1, 2024 · Geodesic polyhedra are defined by the equilateral triangles of the primary face (i.e., the face of the underlying tetrahedron, octahedron, or icosahedron) laid out on a 60° grid so …

Illustrated definition of Geodesic: The shortest line segment between two points on a sphere or other curved surface. A Geodesic Dome is made with...

A geodesic, the shortest distance between any two points on a sphere, is an arc of the great circle through the two points. The formula for determining a sphere’s surface area is 4π r2; its …

Geodesic definition: Also geodesical. pertaining to the geometry of curved surfaces, in which geodesic lines take the place of the straight lines of plane geometry..

Importantly, the world line of a particle free from all external, non-gravitational forces is a particular type of geodesic. In other words, a freely moving or falling particle always moves along a …

A modern instrument for geodetic measurements using satellites Geodesy or geodetics[1] is the science of measuring and representing the geometry, gravity, and spatial orientation of the …

A geodesic is the shortest path between two points on a curved surface, analogous to a straight line on a plane surface. The solution of a triangulation network on an ellipsoid is therefore a …
