Cool trio of vids using Galois Theory to solve an example cubic equation, hope you enjoy:

He also has a playlist deriving the Abel-Ruffini theorem which is great but pretty long.

Pretty cool. Thanks OP.
Really fucking nice.
Thank you for the share, OP.
Watched 10 minutes from the first one already.
Why just a cubic?
Why not a more interesting, say quintic or above, with solvable Galois group?
Every cubic is solvable so I don't see how this is that interesting.
It is kinda interesting, but could have been better.

there is a paper, "solving solvable quintics" which you might enjoy

good watch

Thanks, but sci-hub is down :(

Literally the first result on google is a pdf.
guys could you tell a pleb where he could study abstract algebra and where I could see a list of prerequisites that I need to learn before I dive in?

Thanks then, I didn't bother looking it up because I don't have access to Jstor already.
But looks it's popular enough that many people uploaded it.
And it's by Dummit, cool.

Dummit & Foote, Hernstein, or Artin's.
If you want a really cool and easy presentation with a lot of interesting problems, pick Artin's.
If you want a thorough explanation of the whole problem with shit ton of problems and almost anything that you can think of as an undergrad, Dummit.
Hernstein is in-between, but much closer to Artin.
I'd suggest Artin first.

I'm assuming you mean this one. already got it from libgen and I'm going to start reading it tonigt. thanks friend
why are so many math people so goddamn weird? The dude is staring into my soul, he never blinks

I was thinking the same thing. I thought I was just being autistic
