The Formal Theorem

\forall p \in M, \exists U \subset M, U \cong \mathbb{R}^n

Analytical Intuition.

Manifolds are the Geometry of the Local. Globally curved (Earth) but locally flat (your backyard). Atlases and charts map the curvature. foundation of General Relativity.
CAUTION

Institutional Warning.

Every point has a neighborhood that looks like Euclidean space. The glue between patches must be smooth.
