I am normally not into birding. But here I needed to make an exception. #iceland #puffin #birding

There are almost exactly 20 years between these two pictures. The two fix points that link them are me (modulo the difference of 20 years) and the most beautiful place for mathematicians to visit, Mathematisches Forschungsinstitut Oberwolfach.

The planar Evolute is a fascinating curve with a history going back at least to Apollonius (200 BC) - and the (virtual) ink of its newest chapter is still fresh:"Return of the plane evolute" with Ragni Piene and Boris Shapiro.

4th week of lectures in linear algebra at @uitnorgesarktiske.bsky.social and still more than 60 students (90%) come to the lecture..I guess, I am too nice?

We had the successful kick-off of our new #Indo-Norwegian project: "Mathematical Theory of Data Transmission and Data #Encryption" 🎉. Over the next 3 years, we’ll collaborate closely with our partners to foster educational and research exchanges between #Norway and #India. 🌍📊🔒

This year’s Mørketidens Mattemøte once again brought mathematicians from across Norway and the Nordic countries to @uitnorgesarktiske.bsky.social for two inspiring days of idea exchange and new connections.
Thanks to Tromsø Forskningsstiftelse and Trond Mohn forskningsstiftelse for the support !

The findings of the #TIMSS study are a wake-up call for Norway: a striking 42% of 5th graders and 66% of 9th graders report that they do not enjoy learning math. This is a serious problem – thanks to @aftenpostenoff.bsky.social for allowing us to comment on this

What is academic freedom - especially with a perspective from Germany. Thanks to @forsker.bsky.social ved @uitnorgesarktiske.bsky.social for a chance to discuss this.
