Riemannian theory

Riemannian Theory is a way of looking at things that are curved in a special way. If you picture a curved road like a roller coaster, then Riemannian Theory is a way of making sense of that road. It's all about looking at the angles and distances, and how they change as you go along the curve. It can help us better understand how things work, how space is organized and how different shapes interact.
