Geodesics in general relativity
In general relativity, a geodesic generalizes the notion of a "straight line" to curved spacetime.
Geodesics on an ellipsoid
The study of geodesics on an ellipsoid arose in connection with geodesy specifically with the solution of triangulation networks.
Schwarzschild geodesics
In general relativity, Schwarzschild geodesics describe the motion of test particles in the gravitational field of a central fixed mass that is, motion in the Schwarzschild metric.
