From early morning to late evening; from registration to reception: it's a wrap for the first day of #ECMTB26! Looking forward to more exciting talks, discussions, and the first round of poster presentations tomorrow!

Early morning: fully staffed registration desks. Organisers and student helpers waiting for participants to pick up their nametags

Busy gathering next to the conference office after a plenary talk

Welcome Reception: musical performance of Timber (Michael Gordon) by STUDIO PERCUSSION Graz

Late evening, welcome reception: social gathering in the main building courtyard

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)

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 😆🎉)

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-...

... wobei sie dann natürlich aufpassen müssen, dass die ausführende person keine instruktionen dazuhalluziniert. im rahmen von workshops gut genug um "algorithmus" zu entmystifizieren; gleichzeitig gute brücke um zum eigentlichen workshop-thema zu kommen. (ich mach normalerweise graphen-zeug.)

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 🧮
