From December 23rd to January 1st, we will be showcasing our most notable conversations of the year. Today's guest: Eugenia Cheng. What if gender equality was just a math problem we haven’t yet solved? Eugenia Cheng is Scientist in Residence at the School of the Art Institute of Chicago and a math professor at the University of Sheffield, and she joins host Krys Boyd to talk about taking mathematical concepts and applying them to an issue we’ve wrestled with throughout human history. Her new book is called “X+Y: A Mathematician’s Manifesto for Rethinking Gender.”
