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.
