Eugenia Cheng, author of the cleverly-titled x + y: A Mathematician’s Manifesto for Rethinking Gender, is—goes Wikipedia—“a British mathematician, concert pianist, and an honorary fellow of pure mathematics at the University of Sheffield. Her mathematical interests include higher-dimensional category theory, and as a pianist she specialises in lieder and art song.” Her current gig is Scientist in Residence at the School of the Art Institute of Chicago. Even more daunting, her website features a stint on The Late Show with Stephen Colbert.
