Math of the London riots

Here’s a ten-minute video featuing Hannah Fry of UCL on the London riots of two summers ago. She’s a mathematician, and talks about the mathematics useful for understanding riots:
– the geography of rioting being like the geography of shopping – so certain parts of the city are more susceptible to rioting than others
– predator-prey interactions can br used to model the interaction between police and rioters
– the spread of the idea to riot is like the spread of an epidemic, and susceptibility to rioting seems to be connected to recent cuts in social services.

The original paper being described in this video is in Nature. I learned about it from FlowingData.
