Algebraic Topology (Silly Anthropology Parody)

Thanks to LovelyFluttershy for allowing me to use the instrumental. This is a bit on the nerdy side of things, but hey... I gotta live up to my cutie mark at some point, right?

This is more me venting my frustration about my upcoming exam, than actually trying to produce a masterpiece but I figured, why not upload it? - Maybe someone will enjoy it or just laugh at what a geek I am, either is fine by me XD

For those of you, who doesn't have a clue what topology is, you can view it as geometry but more abstract.

Lyrics:
Firstly homeomorphisms are a tool that we must use,
they are smart because an isomorphism they will induce,
on the n'th homology group thats no lie now don't you see?
It's so real to me, Algebraic Topology.

Barycentric subdivision, why is this damn proof so long,
there's no way that I won't get this god forsaken proof all wrong,
there's 4 parts, each one a page, and I won't make it all in time!
It's annoying me, Algebraic Topology.

And examples is a good way, to get the esssentials in place,
Without them it could be too dry, to not rage quit on the first day!

Cellular homology is used on a CW complex,
here's a proof that's just a commutative diagram, oh shit!
Hatcher sometimes you just kill me, with your lack of rigour, and
it's so frustrating, Algebraic Topology.

Homotopy invariance,
long exact sequences and
excision in homology,
singular or simplicial,
degree of a mapping,
cellular homology and then,
I am finally free, from Algebraic Topology.

But wait I forgot just one thing, the Mayer-Vietoris sequence,
we obtain this from subspaces, whose interiors cover X!

I don't mean to, keep complaining, but i feel the pressure's on,
when the exam comes I fear that... All my knowlage will be gone!

Come on brain just power through it!
I believe that we can do it! YAY!
The exam awaits! Algebraic Topology, AH!
