: Solving the second-order differential equation that describes the path of a particle in free fall:

To illustrate this, consider a simple case: a 2D sphere where we want to find the shortest path between two points. In Riemannian geometry, these are "Great Circles." Why this is helpful: Riemannian Geometry.pdf

: You can use it to check manual calculations for textbooks like M. Spivak's Calculus on Manifolds . Riemannian Geometry.pdf

: It bridges the gap between abstract theory and physical applications like General Relativity , where gravity is modeled as the curvature of spacetime. Riemannian Geometry.pdf
