The most important book in the history of mathematics is Euclid’s Elements, which dates to ~300 BC and is the oldest surviving logical treatment of mathematics as a discipline. Its theorems and constructions are central to the history of scientific discovery and logic. With us to discuss the Elements is David Acheson, who became a Fellow in Mathematics at Jesus College, Oxford in 1977. We discuss his recent book, The Wonder Book of Geometry, published 2020 by Oxford University Press.
