Galois theory is a branch of abstract algebra that studies the symmetry of algebraic equations. It is a fundamental area of mathematics that has numerous applications in various fields, including number theory, algebraic geometry, and computer science. | Feature | Edwards (GTM 101) | Artin

Many modern algebra textbooks introduce Galois theory by asking students to study field automorphisms over arbitrary fields. This approach is powerful but often lacks historical context, making the theory seem arbitrary. Edwards breaks this trend by: Many modern algebra textbooks introduce Galois theory by
