Many Shakespeare fans don’t think of themselves as “math people.” They’re theater kids, poetry lovers, bookworms, right? But in Shakespeare’s world, math and literature were deeply intertwined. In Much Ado About Numbers: Shakespeare’s Mathematical Life and Times, mathematician Rob Eastaway explores how mathematical thinking shaped Shakespeare’s language and imagination.

Shakespeare lived at a moment of major intellectual change, when England was newly encountering Indo-Arabic numerals, experimenting with new systems of calculation, and redefining ideas of measure and proportion. Eastaway shows how Shakespeare delighted in numbers and patterns, playing with “scores,” fractions, and symmetry in works like Othello, Henry V, Romeo and Juliet, and The Winter’s Tale. Even familiar references to “nothing,” time, and music take on new meaning when viewed through a mathematical lens.

In this episode, Eastaway reveals how math was woven into everyday life in Shakespeare’s time and how reading with our “math glasses” on can offer fresh insights into Shakespeare’s language.
