The Lowdown

Étienne Ghys, a distinguished mathematician from École Normale Supérieure de Lyon, delivered a public lecture titled "The Shape of Letters: from Leonardo da Vinci to Donald Knuth" at the 2026 Joint Mathematics Meetings. This presentation delves into the surprisingly rich mathematical underpinnings and artistic considerations that have shaped the alphabet throughout history.

  • The lecture explores the historical development and geometric principles behind letterforms.
  • It connects the artistic and scientific observations of Leonardo da Vinci regarding letter structure.
  • The narrative extends to Donald Knuth, the creator of TeX and Metafont, who brought mathematical rigor to digital typography.
  • The presentation promises an interdisciplinary examination, blending mathematics, art history, and computer science in its analysis of typography.

This talk offers a unique perspective on a ubiquitous aspect of our daily lives, revealing the profound thought and mathematical elegance embedded within the very characters we read and write.
