Maths

Spent the day working at a hot desk on campus; later a couple of colleagues appeared and suggested that we all went out for a meal in a local pub, which made a very welcome change from the usual fare. We had a nice walk for a mile or so to get there, and then had some very decent beer and good food.

Someone had been doing some maths in the common room area - I suspect that the wee illustration of the Arnold family was a later addition.
