Lie Groups: The Geometry of Symmetry that Shapes Physics and Mathematics

Lie groups merge group theory, geometry, and linear algebra to capture continuous symmetries that underpin modern physics and deep mathematical structures. From the rotation of a Frisbee to Noether’s theorem, these manifolds translate abstract algebra into tangible conservation laws and computational tools.
