this was actually quite fun to build; short-ish share links for a static page / no backend or database. :-) (no credit for ui/ux for me, that was all @anja.codes)

last thursday our students organised *profslam*, a very fun and entertaining 10min math talk competition. had a looots of fun telling one of my favorite computer math stories: the fast inverse square root implementation from quake 3 arena! 👀🧑‍💻 interactive slides: behackl.dev/slides/2026-...

very grateful that our students put together such a cool event! I unfortunately didn't win though: this years award went to my colleague Stephan Wagner / TU, for a delightful talk on Catalan numbers and -bijections. (actually quite happy that discrete math won, even if it wasn't my talk 😆🎉)

It's pretty hard to follow up to cool number years like (20 + 25)² = 2025, but I hope you have a great start to 2¹¹ - 2·11 = 505 + 506 + 507 + 508 = 2026. Happy new year! 🥂🍾🎉 (Bonus fun fact: 2026 is the number of disconnected 4-regular graphs on 17 vertices, via oeis.org/A033483 🧐) #mathsky 🧮
