Daaamn, dude, you sure love talking.... So basically what you're trying to obfuscate here, is that there's a function that maps a polynomial over a ring (e.g. the ring of real numbers) to an element of that ring (a real number), and this mapping is just what we know as evaluating this polynomial for a particular α ? Because if that's the case, then I communicated it in 10 seconds instead of half an hour :q
I don’t think you understood the video. He’s trying to show that the function is a homomorphism and for that you have to prove that it satisfies certain properties. Your explanation, on the other hand, was pointless and doesn’t give us any interesting results.
Why is Phi_alpha surjective?
I see that it maps to a Subring of R.
But why is this subring the whole of R?
can you please explain the alpha to the power i at 12: 12? I coud not understand it .
21:45 dafuq did we do here

then make a whole youtube video playlist on ring theory my dude. If it takes you 0.0056% of what it takes this guy, you could get it done in no time!
his playlist is great, this video is getting a bit confusing. your comment helps me.
