I was searching for the arXiv reference for my recent preprint with 2 collaborators but the first hit was an AI synopsis of us as researchers 😂

a lot of people are aware that you can factor 2025 = 45² i'm honored to announce the factorization 2026 = (45-i)(45+i)

Do you know the trigonometric notations of Charles Dogson (aka Lewis Carroll)?

Have you seen the gut-wrenching story “Confronting university harassment: ‘You’re dumb, but you’re a pretty girl’” in thesaturdaypaper.com.au · December 13, 2025?

🥸😆🤣

Very sad that I felt I had no choice but to resign from The Infinite Monkey Cage - a victory for the transphobes and other bigots - I did it because so much of the media has chosen to believe the kind and empathetic people are a fiction - they are real and so often unrepresented.

The mathematical art exhibit at this week’s AustMS also featured stunning works by @mathskath.bsky.social which she has modestly omitted in her posts about it. Behold ⤵️

The next round of our International Visitor Program is now open! Math researchers from overseas, apply now to spend 4+ weeks working with new and existing collaborators here 🦘🌏 Aus researchers, please share: mathematical-research-institute.sydney.edu.au/internationa... Due: 17 Feb 2026 #mathsky

Brazil, where hearts were entertaining June We stood beneath an amber moon And softly murmured "someday soon."

The 2025 AustMS great debate is on “AI will definitely destroy mathematics” 😁

Very sad to learn that Anne Husebekk has passed away. I had the deep pleasure of talking to Anne at the International Science Council meeting in Oman in January. Her discoveries in immunology were astonishing and she was so lovely to talk to, so generous and so wise … council.science/profile/huse...

Can’t wait to hear who wins the FIFA Fields medal 🏅in #mathematics

Do you use Google Scholar? Yes? Then read this and beware ➡️ “Even successful, widely-used academic infrastructure gets the axe when companies decide it's not strategically important anymore.” hannahshelley.neocities.org/blog/2025_08... from @hannahshelley.site via @olivia.science

The Journal of Mathematics and the Arts invites applications for Editor-in-Chief from scholars who understand that mathematics and art are not separate worlds. Help us showcase research that reveals the mathematical soul of creativity. spr.ly/63321AhlWd

Welcome to Australia, where summer *does* start in 🌞 December …

What I forgot to say was that this is visceral; I am literally surrounded by very tall people and have to remember to look down every now and then …

Hmm… definitely at my froggiest 🐸 mode craning my neck awkwardly at stork-like birds 🦢 this week #frogsandbirds www.ams.org/notices/2009...

Great culture can save lives. Literally. Amazing letter in today’s @thetimes.com about Tom Stoppard

A friend sent me a scary quote from ‘What we can know’ by Ian McEwan. It’s set in 2119 with an academic researching aspects of the past, i.e., our present era. /1

We need more words… there are an awful lot of ideas called “entropy” ⤵️ ncatlab.org/nlab/show/entropy

This is Morris Birkbeck Pell (on left), the first ever Professor of Mathematics and Natural Philosophy @sydney.edu.au

Needless to say, I don’t meet these criteria 😁 (♂ ↦ ♀, Cambridge ↦ Princeton…)

When @Sydney_Uni sought to appoint its very first professors, the then Provost wrote to the selection committee in England… /1

I was interviewed by SBS Gujarati a few days ago… As often happens, I had to find a way to explain mathematics, my kind of mathematics... /1

Everyone in my exercise class congratulated me today. It was a bit overwhelming… #NSWScientistoftheYear

Do you remember how a newly minted Fields medallist had his shiny new medal stolen at ICM2018 in Rio? Guess who is speaking tomorrow @sydney.edu.au ⬇️

I am very much looking forward to tomorrow’s SMRI Seminar, ‘The rich world of Fano geometry’ with Caucher Birkar, on Thursday 27 November 1 pm – 2 pm AEDT Location: SMRI Seminar Room (Macleay A12 Room 301) @SydMathInst.bluesky.social

Scientists: have you been the target of an online harassment campaign, doxxing, or weaponized FOIA requests? I'd like to talk to you about steps you had to take to protect your digital security for an upcoming Nature story. (You can be anonymous if necessary.) RTs appreciated.

Congrats to Dr Caroline Wormell from the School of Mathematics and Statistics on their recently announced DECRA award "From chaos to clarity: reliable data-driven analysis of dynamical systems."

i’m not crying you’re crying xkcd: Fifteen Years

ARC says they’ll announce DECRA and LIEF outcomes tomorrow (Tuesday 25th Nov). In recent times these announcements have been around 11am Canberra time. With 2 schemes on the same day, I assume they’ll announce one of them later in the day (probably DECRA first).

I’ve been seen 🫣

ICMY: this December, the School of Computer Science at #USyd will host an absolutely incredible line-up of speakers, jointly with the SMRI (@sydmathinst.bsky.social) and the Faculty of Engineering! 🗓️ Mon 1: Bob Tarjan 🗓️ Tue 2: Moti Yung 🗓️ Wed 10: Shafi Goldwasser Details and how to attend below! ↴

An article from @sydney.edu.au about today’s significant event #NSWPremiersPrizes news-opinion.sydney.edu.au/link/id/zzzz...

From today’s Sydney Morning Herald

The journey from proto-asymptotologist to integrable-systems analyst to applied algebraic-geometer has been fun. Now I have to explain what that means in 3 minutes. How can I possibly do this without a chalkboard 👩🏽‍🏫?

Today I talked to journalists from the Australian and Sydney Morning Herald. Tomorrow it will be Craig Reucassel @reucassel.bsky.social on ABC Sydney at 07:50am … Stay tuned

Hope someone can help me? The copy I have access to of volume 4 No. 1 (1980) of "AEB. Analytical & Enumerative Bibliography" is missing pp. 14 and 79. This appears to be a problem with that specific copy, since I have not found a reported erratum (or the missing page printed) in later volumes. 1/
