Évariste Galois

Évariste Galois was a French mathematician who made groundbreaking contributions to algebra. He developed the theory of groups, providing a systematic way to understand symmetries in mathematical equations. His work explained why some polynomial equations can be solved using radicals (like square roots) and others cannot. Despite dying young in a duel at 20, Galois laid the foundation for modern algebra and influenced fields like cryptography and coding theory. His insights transformed our understanding of equations and symmetry, making him a key figure in the development of abstract mathematics.
