    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 .

    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

      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.

      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.
