Conference in Boulder

Last week, a large part of the group visited the twenty-second symposium on thermophysical properties in Boulder, Colorado in the US. It was a very long trip with Trondheim as the starting point, but it was nice to meet so many people again in person. Five people from the group were attending. Tage Maltby presented about the …
