Geodetisen

Geodetisen is a term that appears to be a misspelling or a less common transliteration. The most likely intended term is "geodesic". A geodesic is the shortest path between two points on a curved surface. It is a generalization of the straight line in Euclidean space to curved spaces.

In differential geometry, geodesics are curves that locally minimize distance. Imagine stretching a rubber band between two points on a sphere; the path the rubber band takes is a geodesic. On a flat plane, a geodesic is simply a straight line. On a sphere, geodesics are great circles, which are circles on the sphere whose center coincides with the center of the sphere.

The concept of geodesics is fundamental in various fields. In general relativity, the paths of objects moving freely under gravity are described as geodesics in spacetime. This means that gravity is not a force in the traditional sense, but rather a manifestation of the curvature of spacetime, and objects simply follow the "straightest possible paths" within this curved geometry. In cartography, geodesic calculations are used to determine the shortest distances between points on the Earth's surface, which is an imperfect sphere. Computer graphics also utilizes geodesics for tasks like shortest pathfinding on complex surfaces.
