Mathematical modelling of Zombie attack

I know it is the silly season but this is so brilliantly silly it is vital that everyone reads it. The BBC are quoting a research paper on zombies and mathematical modelling of a zombie outbreak. Now I know a bit about zombies and have studied the Zombie Survival Guide and the World War Z: An Oral History of the Zombie War. However, the mathematical model makes for grim reading: to quote from the end of the paper “In summary, a zombie outbreak is likely to lead to the collapse of civilisation, unless it is dealt with quickly.” I would stress, however, that in the event of a zombie apocalypse any unionist / nationalist cooperation can only be temporary.
