We completed a 2-day kindergarten mathematics conference. It was a great conference with a diverse range of talks and workshops and great social events. I did a talk on mathematics and rhythm with Carl Haakon Wadeland, a professor of music and well-known drummer who's played with many famous Norwegian bands, including currently the very popular children's band Rasmus og Verdens Beste Band (Rasmus and the World's Best Band). We had so much fun practicing and performing together... we're both glad we'll get a chance to do it again in Oslo in a few months. I also got to meet and chat with was Rasmus (also from Rasmus og Verden's Beste Band). He closed the conference for us with a Q&A sesson and played several songs for us – quite a treat!
