As mathematicians, we explore abstract questions, yet history shows that these ideas often become the foundations of transformative technologies 🧮📱 This weekend of #InternationalDayOfMathematics we are proud to announce a landmark $55.1m co-investment in SMRI🧵 www.sydney.edu.au/news-opinion...

It was a great day! Happy weekend of #InternationalDayOfMathematics #MathSky

Full house for tonight's public lecture 'A world from a sheet of paper' #InternationalDayOfMathematics #MathSky

We are kicking off #InternationalDayOfMathematics with a maths colloquium by Tadashi Tokieda: Irrational ways of manufacturing numbers #MathSky

I gave a talk* in the NSW Science & Research Breakfast series organized by the NSW Chief Scientist and Engineer’s Office. I can’t watch myself but ICYMI 👇🏼 m.youtube.com/watch?v=1hxJ... (*Can you spot the point where I misnamed the author whose famous book contains an attack on a Playfair code?)

The Tait conjectures for classical, virtual, and welded knots — Hans Boden, McMaster University youtu.be/rx1dwhuQkdc #MathSky #SMRISeminar

If you were thinking of joining us for Tadashi Tokieda's 'A magic show', we have added two extra sessions 🗓️ due to demand on Sat 14 + Sun 15 March: events.humanitix.com/a-magic-show... 🎩🐰 This will be part of 'Maths at the Museum', curated by SMRI for International Day of Mathematics #MathSky #Syd

✨Highly recommend Geordie Williamson's brilliant talk. We were lucky to meet Geordie in Sydney in 2022 at @sydmathinst.bsky.social , he lives by his own words: "Mathematics is humanity's longest conversation."✨ youtu.be/0Tgftb5ELvE?... via @YouTube

We are excited to formalise our partnership with @matrix-inst.bsky.social , the only residential research institute in the mathematical sciences in Australia. As an Associate Member, SMRI and @sydney.edu.au look forward to increasing our engagement with MATRIX 🧮🌏 #MathSky

MATRIX is thrilled that the University of Sydney, through the Sydney Mathematical Research Institute, will join MATRIX as an Associate Member from 2026. USyd joins MATRIX partners Monash University, the University of Melbourne and UQ, along with Associate Members the ANU and UNSW, Sydney.

🔝SymplecticGeometry has its roots in physics. To take a simple example, imagine a pendulum. Don't miss the video of #HolgerDullin and #FranciscoCrespo and how the role of symmetry can change everything! @sydmathinst.bsky.social @sydneymathsstats.bsky.social youtu.be/fdeh3lljA_Q?...

If you’re gripped by the wave of stories giving one side or the other of “AI vs Mathematics”, you may be interested in the tidal flow described in this recent interview with @teorth.bsky.social www.theatlantic.com/technology/2...

Ever wondered what it means when mathematicians talk about 4 dimensions? Zsuzsanna Dancso discusses in #TheConversation 'Why you can't tie knots in four dimensions' 🧮🪢 Explore the difficulty of visualising and exploring higher-dimensional spaces! #MathSky theconversation.com/why-you-cant...
