Frisbee

A morning helping with data analysis and an afternoon off - well, an afternoon in which I was still working, just different work. I went out to take some photos of the students v tutors extreme frisbee match, but got distracted by the beautiful beech tree in the foreground. (Students 2, tutors 19, apparently). It was oppressively hot, both indoors and out.

Then an evening session about energy, a quantity in short supply this week.
