For this episode of Relatively Prime Samuel decided that instead of speaking to a guest they would instead talk about the research they are conducting now that they are the Mathematics & Statistics Librarian at the University of Michigan. This research looks into how the citations of mathematical publications age over time, and its discussion includes a first for Relatively Prime - Data Sonification! These sonifications were created using Jonathon Middleton's website Musical Algorithms (you hear more about Jonathan and this site on the Relatively Prime Season 1 episode The Score)
