What does the French revolution, a deadly duel and squaring a circle have to do with the birth of modern algebra? SMRI’s public lecture on 14 March was part of celebrations for the 2023 International Day of Mathematics, aka Pi Day 3.14.

“Duels and Duality: A fable about the life & mathematics of Évariste Galois” was presented by mathematician Oded Yacobi of the University of Sydney.

Esteemed algebraic number theorist Professor Frank Calegari gave a public talk on the secrets of Pi, presented by SMRI as part of his 2022 Mahler Lecture Tour .

In this talk, Frank explored a conjecture (formalized by Grothendieck) which explains how seemingly different occurrences of Pi (as well as many other interesting mathematical constants) should all be related, and how these numbers are linked to some the biggest open problems in algebra and number theory.

SMRI Director Professor of Mathematics Geordie Williamson explored how machine learning can help with the intuitive aspects of mathematical research. Geordie carried out one of the first applications of AI in pure mathematics, in collaboration with Oxford University mathematicians and DeepMind, the AI company of AlphaGo fame. The results were published in the prestigious scientific journal Nature in December 2021.

This public event took place on 15 March 2022, co-presented with Sydney Ideas.
