When I began my math major coursework (in 2007), the biggest hit math song at Portland State University Math Dept. was Weird Al's "White and Nerdy." But by the time I complete my degree a couple years later, the biggest math hit was underground sensation the Klein Four's mathematical-jargon-in-every-line a capella YouTube jam Finite Simple Group (Of Order Two).
If you're curious about all the mathematical references - many of which won't be obvious to non-mathematicians - you can check out CJ Quines's ridiculously detailed breakdown from 2022.
Or just enjoy an aging math nerd's ukulele version…
I'm a little bummed that I didn't have time to work out a version of Tom Lehrer's "Wernher von Braun" this Season. Hopefully, we'll have an antifascist season sometime, and I can get it together then 😛
