## The mathematics of twisting somersaults: National Science Week 2023 public lecture

What do a space station, a falling cat, and a springboard diver have in common?

They are able to reorient themselves while in free fall. In this talk by University of Sydney mathematician Professor Holger Dullin, we’ll explore the principles behind this phenomenon.

## Women in Mathematics Day 2023 “Olga Ladyzhenskaya” film screening

To celebrate Women in Mathematics Day (12 May), SMRI is hosting a screening of the short documentary “Olga Ladyzhenskaya” (2022) by acclaimed filmmaker Ekaterina Eremenko.

Everyone is welcome, particularly high school and university students of all genders.

## 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? 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.

## The secrets of Pi and other transcendental numbers

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 .

Throughout the centuries, the number Pi has come up again and again in mathematics in many totally different contexts — as the special value of various integrals, the solution to questions in probability, and many more places.

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.

## Maths, AI and intuition with Geordie Williamson: Sydney Ideas event

SMRI Director Professor of Mathematics Geordie Williamson explored how machine learning can help with the intuitive aspects of mathematical research. Geordie recently 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.

## POSTPONED: The Mathematics of Knots with Jessica Purcell: Public Lecture

Since prehistoric times, humans have used knots for their functional and aesthetic value. Knots, links and braids have held decorative, artistic and spiritual significance across a myriad of cultures. For mathematicians, the study of knots has led to insights in disciplines such as geometry and topology.

In this public lecture, upcoming SMRI visitor Professor Jessica Purcell will provide us with an introduction into knot theory and some of its fundamental questions.

Professor Purcell will take a look at some of the modern tools to study knots and describe some of the surprising applications of knot theory.
