302.S9A: Galois Groups and "Stubborn" Polynomials 

Subgroups are dual to subfields -- the Galois correspondence. "Always two there are" -- Yoda.

As I have said before, these videos are really, really good! I'm getting to understand the whole theory, but will need to do more work to master it. Could you recommend any suitable text and/or excercises which would aid my understanding? Thanks

1:28 I don't see anything to click on screen 😥 But in any case, thanks for another outstanding video!

This is where galois theory always loses me. The roots have to be complex numbers, and aren't there numerical algorithms for finding the actual values?

I would kill to study under you, my Galois teacher doesn't publish videos online for study and his notes are very dense and 90% difficult to follow proofs. His tests are ridiculously difficult with an average grade of 41 and he frequently makes mistakes when lecturing.
