🔢 Manneken Pis wordt weer Manneken Pisthagoras! Over exact 1 maand, op zondag 29 november 2026, haalt onze bekendste Brusselaar zijn @VUBrussel - Vakgroep Wiskunde kostuum, ontworpen in het academiejaar '20-'21, opnieuw uit de kast! 1/3

De datum is wiskundig bijzonder: 🔹 29 is een priemgetal én de hypotenusa van de "Pythagoriaanse driehoek": 20² + 21² = 29² 📐 🔹 29 november is de 333e dag van 2026. Een prachtig palindroomgetal 🤩 2/3

The largest math proof in human history is now computer-verified. Today, Axiom announces a complete Lean auto-formalization of the Classification of Finite Simple Groups, the "periodic table of symmetry." About 15,000 pages, built by over 100 mathematicians across generations.

Op 2 december is er een tweede studiedag in deze reeks voor BaO. Deze keer met focus op vakinhoud wiskunde. Keynotes @timsurma en @FilipMoons Initiatief van @platform_wis_VL #iSTEM #Technopolis #STEMvoordeBASIS #VVWL en de onderwijskoepels. technopolis.be/nl/scholen/st…
Ik kijk enthousiast terug op dit initiatief van #iSTEM en #Technopolis. Heel blij dat dit kon met medewerking van álle onderwijskoepels! Dank ook aan de lesgevers van #STEMvoordeBASIS voor de inhoudelijke invulling. @onderwijs_Vl @Zu_Demir nieuwsblad.be/regio/antwerpe…

I’m excited to announce that I will be working at the Mathematical AI Safety Institute (MAISI) full-time as its founding Scientific Director! This means I will not be joining OpenAI as an employee, though I will still be collaborating with them, and I’m happy to announce that OpenAI will be supporting MAISI. They have offered us $10MM in API credits, and access to their latest models for our research use. Moreover, they will be participating in a multi-lab AI safety workshop we are organizing for next year with other frontier AI labs. As an independent research institute, we are also in conversations with other labs and AI safety orgs about how MAISI can collaborate with them and contribute quickly to AI safety research across the industry. As we’ve seen over the past few weeks, the need for action on AI safety is extremely urgent. Research is an important part of that, and mathematicians have an important role to play!

If guided wisely, AI will not diminish the mathematician’s role but will broaden it: mathematicians will become designers, curators & interpreters of intelligent systems that, in turn, help humanity deepen its understanding of the mathematical universe. zenodo.org/records/18205480

Bedankt @Zu_Demir om het belang van een bekwaamheidsbewijs te erkennen in de commissie. Het is wel onduidelijk of dit gaat om een vereist of voldoende geacht bekwaamheidsbewijs.

Not to be missed!
Why should mathematicians care about European PISA results? Join Professor Nuno Crato (University of Lisbon) tomorrow, 9 October, at 16:00 CEST for a lecture and discussion. Organised by @soccatmat & @euromathsoc Education Committees. Join via Zoom: us02web.zoom.us/j/8759268063…

Absolutely! This is the PISA paradox: designed to assess competences, it reveals that training students in applied problem-solving falls short, while building deep knowledge leads to good results
“In short, PISA is a screen-based test of problem-solving skills that requires limited specific curriculum knowledge. If you wanted to design a test that would be *least likely* to reward England’s educational approach, and *most likely* to reward the approach in Scotland & Wales, it would be PISA. And yet, England are still doing better on it.” 🎯 🎯🎯
