The “Star Wars Cantina Theme” Played Out By Writing An Equation

You ever get a song stuck in your head and then you start to hear it everywhere? I'm sure that's what happened to this girl.

She posted a video where she writes down a long math equation. If you listen closely, the sound of her pencil on the paper plays the "Cantina Theme" from "Star Wars". As a bonus, she also posted one where she does the same thing with the "Imperial March".
