Lie Groups Unfolded: Continuity, Symmetry, and the Geometry of Change

Explore how continuous change led Sophus Lie to fuse geometry and algebra into Lie groups and Lie algebras. We’ll build intuition from circles and matrices, explain the tangent-space Lie algebra, the Lie bracket, and the exponential map, and show why local linearization captures almost all the physics and geometry—yet global topology can still surprise us (SO(3) vs. SU(2)). We’ll connect to Klein’s Erlangen program and modern physics, from rotations to the Standard Model.
