This weekend has been one of those weekends when everything seems to come at once. It was open day at university, the clocks have gone back an hour and the pump on my water cooled PC appears to be having problems and might need to be replaced. Although most of Saturday was taken up with work, I’m still trying to keep up to date with both my streaming schedule and my blogging. It was, however, at Open Day that the idea for this week’s waffle first started as a seed in the quagmire compost where my waffling ideas sprout. Do we learn because we are curious or because we have to?
