“Every day I discover more and more beautiful things. It’s enough to drive one mad.” ― Claude Monet Art by Claude Monet, The Cliff Walk at Pourville (1882)

A shiver runs down my back whenever I read a paper that references C.L.Dodgson, Condensation of determinants, Proc. Royal Soc. London 15 (1866) 150-155. Do you know the work of Dodgson? Let me give you a hint

What do mathematicians do? How do they make new mathematical discoveries? Why does that matter for K-12 math education? If you are a math teacher and you are curious about these questions, join in on "21st century mathematics" in July! Free, online, and flexible. www.youtube.com/watch?v=5UIx...

#DiscoveryProjects #DP27 Detailed assessor reports should be released in ARC's RMS tomorrow (23 Jun). Normally about 11am, Canberra time (but it varies). Remember the #ARC3DayRule: Think an assessment is "inappropriate"? You've only got 3 days to lodge a "request for review" 👇

Hi! In July I'm once again running a free online program for K-12 math teachers called "21st century mathematics". Its goal is to help teachers to connect math they teach with some math that has been discovered in the 21st century. Pass it along! Info+register: justinlanier.org/21st-century...

Sigh 😔 the myth of the awkward, mad #mathematician continues to propagate in all levels of social discourse …

Hi @asharao.bsky.social my students are asking if is there somewhere they can find out more about the AMSI course on cryptography? The lecturers are from RMIT I believe. 🙏🏽 in advance…

When I was younger, I thought that The Counterexample would be a cool supervillain. Now that I'm older, I realize they are really a brooding antihero, whom no one wants be around but who will be called when it's absolutely necessary

#BeijingScienceDialogue: The Beijing Science Dialogue, convening more than 250 scientific organizations across the world, will be held from 19-21 October 2026.   Following the public Dialogue, the ISC Midterm Members' Meeting will take place from 22-23 October 2026. https://council.science/Beijing/

It's interesting that mathematicians now feel a strong urge to put the word "human" in front of the word "proof".

"People submit too many papers to ML conferences" Meanwhile, at IEEE Transactions on Wireless Communications: "You may not submit more than 36 papers per year." Apparently this is a new policy. I would be super curious to see the stats on how many people are submitting more.

This terrific article by Siobhan Roberts could help elevate the public discussion of AI in mathematics. The interview about the Leiden Declaration is especially helpful. www.nytimes.com/2026/06/02/s...

We're hiring! As part of the "Women in Engineering" initiative at #USyd, the School of Computer Science is hiring women-identifying academics at Lecturer, Senior Lecturer, and A/Professor levels! (≈Asst, Assoc, and full prof) ⏰ Apply by July 13 (Sydney): usyd.wd105.myworkdayjobs.com/en-US/USYD_E...

Teaser: a colleague (Sasha Rubin) and I are planning a 3-day (free) "intensive Winter school" at #USyd on computational complexity: specifically, interactive proofs (IP=PSPACE) and the PCP theorem. July 22-24! I don't know how many people here are nearby and keen, but if you are: please do join!

Thank goodness, now there's somewhere to submit that project I've been stalled out on for three years...

Buried the lede :). There's already an improvement on this result by Will Savin. To n^{1.014}. arxiv.org/abs/2605.205...

You may find the comments by Melanie Matchett Wood on the discovery of a counter example to Erdős’ Unit Distance Conjecture as interesting as I did 👇🏼(see previous post for a link)

There is a very interesting discussion going on in mathematics about cross-fertilization with AI. If you haven’t heard about the latest announcement you can read about it here in a post by Gil Kalai gilkalai.wordpress.com/2026/05/21/a...

See invited addresses from #JMM2026 on YouTube. Today’s video: Geordie Williamson, University of Sydney, gives the first AMS Colloquium Lecture, asking “Can AI help us discover interesting mathematics?” Watch today: https://youtu.be/0Tgftb5ELvE#JMM2026

Thanks everyone for your answers… But note that I am also looking for exceptional day-to-day workplaces that are built for #mathematical collaboration; they don’t have to be in far-away locations that you might go to once in a lifetime or sabbatical …
