This is your final week to apply for the Professor Harry Messel Research Fellowship. A 3 year position open to women in any area of #Physics or #Astronomy at the University of Sydney @sydney.edu.au Deadline: 16th November ⚛️ 🔭 ☄️

Our call for nominations for the Hardy Lectureship 2025 is open! Nominate a distinguished mathematician based outside of the UK to give a series of lectures within the UK. Previous Hardy Lecturers incl. Emily Riehl, Eva Miranda, Nalini Joshi. ➡️ www.lms.ac.uk/events/lectu...

Do you know where I am? #mathematicallife

🚨 #DiscoveryProjects #DP26 announcement: ❗️Outcomes announced publicly for Discovery Projects 2026❗️ See ARC's RMS for list ➡️ rms.arc.gov.au/RMS/Report/D... /bot

Translation for last year PhD students: You want to watch the ARC webpage tomorrow to see who will be looking for postdocs in 2026

ARC says Discovery Projects outcomes will be tomorrow (Tuesday). Linkage Projects (2025, round 1) on Wed. Over past ~year, it's often been at about 11am (Canberra). My bot will pick up the change to RMS & post immediately. ARC should email outcomes to lead CIs, but might take an 1hr or so for DPs

But who looks at h-index in math anyway?

Imagine being a young PhD student, who over the first 2 years of their degree, had to sledgehammer posts into a ground the size of 57 tennis courts, string up copper wires on them, and then spend the last year analysing a paper roll of readouts that was over 5km long… /1

This week has been a surfeit of riches, with a graduation ceremony for my PhD student, Josh Holroyd, and an Honorary Doctorate for a heroine of mine, Jocelyn Bell Burnell, whom I got to meet 🥳 👉🏼 en.wikipedia.org/wiki/Jocelyn...

What is it about the neurological blueprint of people that when I request information, they respond with “Please forward him the attached information. He will then directly receive…”? 🤷🏽‍♀️

Asked my pal from Somerset if he knew anyone capable of taking the square root of -𝑟². "I are!" he said. That's a proof by country diction.

I wasn't allowed to post my latest quantum computing joke. Was told it violated the no-clowning theorem

I discovered today that there is a movie called “Prime”. But I can’t watch it because the plot is too composite. 🥁

Always fun to see the amazing people who win. Congrats to mathematician Lauren Williams on winning a MacArther genius grant! www.macfound.org/fellows/clas...

So I had to call the global help desk, be on hold, ask to be called back, get a human person’s advice, call again on another medium that allows screen sharing, and now have the request partially saved waiting for more input. (The advisor had to look up manuals too…) #perennialbureaucracy 🤷🏽‍♀️

We are thrilled to congratulate Professor Richard Robson FAA FRS on being awarded the Nobel Prize in Chemistry. Learn more www.science.org.au/news-and-eve...

Umm tell me what the difference is again: “Recruitment reports”, “Recruitment reports for Recruitment reports”, “Recruiting”, “Recruiting jobs” … #bureaucracy

Today I turned up to give a lecture and it turned out to be the wrong day 🤦🏽‍♀️ Maybe the universe is telling me to slow down…

Legend: 🥙 = all ingredients in place, 🌾 = just ripening, 🍚 = nice but empty calories, 👾 = excited weird computation, 🤯 = mind blown, 🕳️ = rabbit hole …

I tried to classify the unfinished mathematical problems lurking in my brain: 🥙, 🌾, 🍚, 👾, 🤯, 🕳️ …

The saltiness of analysis, the sweetness of algebra, the umami of algebraic geometry, the bitterness of contradictions, the sourness of dead ends …

I'd be curious to taste mathematics.

Do mathematicians rely on senses other than vision and hearing? 👉🏼 mathoverflow.net/questions/44...

It’s my PhD advisor Martin David Kruskal’s 100th birthday today en.wikipedia.org/wiki/Martin_... Celebrated for solitons, Kruskal-Szekeres coordinates and the Kruskal count ♣️♦️♠️♥️, always missed …

I just learned that a planar tree with one vertex is called a corolla, and I keep wondering if the Toyota Planar Tree With One Vertex would have been quite as successful.

A law of conservation of difficulties: there is no easy way to prove a deep result. But only finding complicated ways to prove a result doesn’t mean it’s deep … 😮‍💨#mathjokecuttingclosetoreality

Classification of mathematical problems as linear and nonlinear is like classification of the Universe as bananas and non-bananas. #mathjoke

“Unlike human intelligence, it lacks the humility to acknowledge uncertainty, …When unsure, it doesn’t defer to deeper research or human oversight; instead, it often presents estimates as facts.” 🤨 Like some researchers I know… www.computerworld.com/article/4059...

This would be an important breakthrough if it holds, but I'm skeptical on first glance. Large parts of this were clearly written by a generative AI. Doesn't mean it's wrong, but I suspect it's a "vibe theorem", i.e., not a theorem. I'll wait for Vidick, Regev, etc. to weigh in.

There is a new claim by Yifan Zhang arxiv.org/abs/2509.12341 that the method currently considered to be the *best* protection we have against Shor’s algorithm on future quantum computers, is vulnerable … #PQC #mathematics

Tell me what’s wrong with this picture #mathsky

SCOOP: The Trump administration has installed a new acting director of the Census Bureau, @npr.org has learned. George Cook takes over the federal government’s largest statistical agency after it's been thrust into the middle of a renewed attempt by President Trump to alter the national head count

Of all the stupid things that this regime has done, this is right up near the top. Postdoctoral researchers come to the US on H-1B visas. This will further destroy the US science enterprise. Stupid stupid stupid.

I asked ChatGPT to create a picture of a young me sliding down an elliptic curve 🤔

I feel like I should be able to crochet elliptic curves 🧶 Has anyone done this yet?

🤔… maybe I should feed it one of my #mathematics problems 😁

💻🧪 Applications are open for our Computer Science Small Grants, where grants of up to £1,000 are available to support collaborative research at the interface of mathematics and computer science. Deadline: 22 October ➡️ www.lms.ac.uk/grants/compu...

Union members at the ABC and across the media industry stand with John Lyons and reject the US President’s unfounded attacks on our colleague. #MEAAmedia

Have you encountered barriers to accessibility in conferences and events? There are so many, even in mathematics conferences I have seen that are run by people with experience. Would you like to help minimise these barriers? 👇🏼

The chiral Potts model “is out of the class of all previously known models and raises a host of unsolved questions which are related to some of the most intractable problems of algebraic geometry which have been with us for 150 years.” 👊🏼 👉🏼 en.wikipedia.org/wiki/Chiral_...
