Mathematics has a smell. This is not a metaphor — not for Vera Szabo, whose rare form of lexical-gustatory synesthesia extends to numerical symbols, causing each equation to produce a distinct olfactory sensation. Prime numbers smell of burnt wood. Differential equations smell of salt. Infinity smells of nothing, which is, she argues, the most terrifying smell of all. This book is a synesthetic memoir of a mathematical career conducted through the nose — a journey through the fragrant landscape of pure abstraction, where the Riemann Hypothesis smells of old copper and Gödel's incompleteness theorems smell of wet earth after rain.
