Galois Theory Unlocked: Symmetry, Fields, and Solvability

A friendly dive into the fundamental theorem of Galois theory. We connect field extensions and Galois groups, explain the inclusion-reversing correspondence between intermediate fields and subgroups, and illuminate the power of symmetry in understanding polynomial equations. Through concrete examples—like the Klein four group from Q(√2,√3) and the splitting field of x^3 − 2 over Q—we see how FTGT reveals structure, guides solvability by radicals, and turns abstract ideas into a coherent blueprint of algebra.
