Élie Cartan

Élie Cartan was a pioneering mathematician renowned for his work in geometry and mathematical physics. He developed advanced techniques to study the geometry of spaces that can bend and twist—called differential geometry—which are fundamental for understanding the fabric of the universe, including Einstein’s theory of relativity. Cartan introduced tools like moving frames and exterior calculus, helping mathematicians analyze complex geometric structures systematically. His contributions have deepened our understanding of curvature, symmetry, and the mathematical foundations underlying modern physics and geometry.
