In June scientific editor Elleke Bal from @trouw.nl visited the Science Jam by Prof. dr. Jari Saramäki (@jsaramak.bsky.social) and spoke to several of our members. Below you can find the article (Dutch only) she wrote on Complex Systems: www.trouw.nl/wetenschap/c...
Complexiteit is, nou ja, complex, maar deze onderzoekers proberen er vat op te krijgen
Een zwerm spreeuwen vormt een complex systeem, net als bijvoorbeeld de menselijke hersenen, financiële markten en klimaatverandering. Het lukt steeds beter om deze systemen te begrijpen.

It was a pleasure having such brilliant participants at the 'Introduction to Complex Systems' Summer School @ccss-uu.bsky.social #utrechtsummerschool. This week has flown by and I thoroughly enjoyed seeing them all learn and have fun getting their head around the many #complex phenomena discussed.
