Something Disturbing

Watch the following video in the following time, in which a top will appear: 11:15, 26:30, and 49:10. There is a top moving, and for a very LONG time.

Title says it all: When Zombies Attack! Mathematical Modelling of an outbreak of Zombie Infection.

That is marketing genius I tell you. It might as well apply to other infections, although zombies are quiet different.

Nice stuff to think about, eh?
