"[Cheng] conveys the spirit of inventiveness and creativity in math... Refreshing is the word that keeps coming to mind."
--Steven Strogatz, as quoted in the New York Times
"Dr. Cheng...has a knack for brushing aside conventions and edicts, like so many pie crumbs from a cutting board."
"[Eugenia Cheng's] tone is clear, clever and friendly. Even at her most whimsical she is rigorous and insightful... [She is] a lucid and nimble expositor."
--Alex Bellos, New York Times Book Review
