Duels and Duality: A fable about the life & mathematics of Évariste Galois

Public lecture by University of Sydney mathematician Oded Yacobi to celebrate Pi Day

Duels and Duality: A fable about the life & mathematics of Évariste Galois

What does the French revolution, a deadly duel and squaring a circle have to do with the birth of modern algebra? In this talk, we’ll explore the amazing (and amazingly short) life of Évariste Galois, and the ideas he developed to solve problems that had bedevilled mathematicians for centuries.

With University of Sydney mathematician Oded Yacobi, we’ll explore the power of symmetry in mathematics, and how seemingly abstract ideas can have profound effects…even on our lives today.

Event format (6–7pm): 45 minutes public talk, followed by 15 minutes question time.

Post-event activities (7–8pm): refreshments and optional mathematical activities.

This talk will be accessible to anyone with an interest in mathematics. Senior high school students are encouraged to attend!

About the speaker: Oded Yacobi is Associate Professor of Mathematics at the University of Sydney, where he is a member of the Algebra Group. His interests are in representation theory, which is the mathematical study of symmetry and involves many other areas of mathematics such as geometry, topology, and number theory.

Oded received his PhD in 2009 from the University of California, San Diego, and before arriving in Sydney held research positions at Tel Aviv University and the University of Toronto. Outside of the university, he can be found playing soccer with his two boys, or taking unnecessary risks surfing at Maroubra Beach.
