Abstract
Every time I mention that I’m a mathematician to someone new, the most popular response is ‘Oh I was TERRIBLE at maths!' and a general vibe that I’m extremely strange for not sharing in this feeling. Honestly, as mathematicians, we are a bit different, but I am going to try and explain why we’re not that strange in this talk. To do this I will provide some stories of my own mathematical journey and why I ended up loving it.
About the speaker
Jordan is a descendant of the Birri Gubba people, Associate Dean of Indigenous Strategy and Services and Applied Mathematician at the University of Sydney. He completed his PhD at the Australian National University in 2019 developing methods to model the inundation caused by tsunamis and storm surges. His current research, begun as a post-doctoral researcher at the University of Adelaide focuses on modelling the interaction between ocean waves and sea ice, which forms as the ocean’s surface freezes. This interaction influences the annual growth and melt of sea ice, which is a key indicator and driver of the Earth’s climate.
IMMC National Winners Presentation
- Friday, 1 Aug 2025, 11am - 1pm
Room 1.33, Hanna Neumann Building #145
Join us at the Mathematical Sciences Institute (MSI) as we celebrate the outstanding achievement of the Australian national winners of the International Mathematical Modeling Challenge (IMMC).
This special event will feature a 30–40 minute presentation by the winning team from Canberra College, who will showcase their innovative solution to a global challenge—designing a seasonal structure for a Global Basketball League (GSL). Their project explores issues of fair play, logistical feasibility, equitable travel, and environmental impact, combining sport and applied mathematics on a global scale.
Following the student presentation, Professor Barry Croke will deliver a short talk, offering reflections on mathematical modelling and its real-world applications.
This event is open to all staff, students, and members of the public with an interest in applied mathematics.
P-adic Numbers and Some Applications
- Friday, 1 Aug 2025, 2 - 3pm
Room 1.33, Hanna Neumann Building #145
- Snehinh Sen
Abstract:
This talk is meant to be a gentle introduction to the fascinating world of $p$−adic numbers. This is a realm where $p^{n}$ keeps on becoming smaller and smaller as we increase $n$.This will be followed by a discussion on three fascinating applications - one from algebra/analysis, one from combinatorics/geometry, and one from algebra/number theory… quite a wide range, right?
