I was offline yesterday because I was giving the Beishon Memorial Lecture at the OU and needed to focus on important matters like logistics and car parking for guests. The title of the lecture was “The Social Life of Networks” and there’s a pdf here if you’re having trouble sleeping. There will also be a webcast, but it hasn’t emerged from editing yet.

Thanks to James Miller, eagle-eyed as ever, who spotted several typos and a glaring error in a calculation!
