The intuition behind Galois Theory, is that in order to find solutions based on radicals (polynomial functions of the coefficients), one has to do it in a consistent step-by-step manner. In Galois theory one progresively constructs group extensions of a polynomial equation in a step-by-step (or root-by-root) manner.

Webwe hear the word symmetry, we normally think of group theory. To reach his conclusions, Galois kind of invented group theory along the way. In studying the symmetries of the solutions to a polynomial, Galois theory establishes a link between these two areas of mathematics. We illustrate the idea, in a somewhat loose manner, with an example. 0.1. Weban important role in the history of Galois theory and modern algebra generally.2 The approach here is de nitely a selective approach, but I regard this limitation of scope as a feature, not a bug.

"WebGalois theory is a very general way to attach groups to algebraic objects. At their basic they allow you to study solutions of algebraic equations. Already that is a huge topic: the pinnacle of modern mathematics called "Langlands program" studies non-abelian Galois groups and their representations. " - Galois theory youtube
