# (Co)homology: A Poem

I was recently (avoiding doing my homology homework by) reading through some old poems by Shel Silverstein, author of The Giving TreeA Light in the Attic, and Falling Up to name a few. Feeling inspired, I continued to procrastinate by writing a little poem of my own - about homology, naturally!

Homology, homology,
I’ve become rather quite fond of thee.
From $\pi_n$ an oasis,
counting holes in weird spaces,
you’re such a great part of topology!

Homology, homology,
although I only know of three:
simplicial to singular,
the third is called cellular,
they're all just making me so happy.

Homology, homology,
labeling things up to homotopy.
With Mayer and Vietoris,
you've the right smidgen of group theory.

Homology, homology,
“What’s that?” I ask, “What’s this I see?”
