Zombie-Attack ScienceNew York Times ninth annual "Year in Ideas" issue (Thanks, Daniel!)
Working with a professor and two other graduate students, Munz built a mathematical model of a city of one million residents, in which an outbreak occurs when a single zombie arrives in town. He based the speed of zombie infection on the general rules you see in George Romero movies: after getting bitten, people turn into zombies in 24 hours and sometimes don't realize what's happening to them until they change.
When he ran the model on a computer, the results were bleak. "After 7 to 10 days, everyone was dead or undead," he says. He tried several counterattacks. Quarantining the zombies didn't work; it only bought a few extra days of survival for humanity. Even creating a "cure" for zombification led to a grim result. It was possible to save 10 to 15 percent of the population, but everyone else was a zombie. (The cure in his model wasn't permanent; the cured could be rebitten and rezombified.)
There was only one winning solution: fighting back quickly and fiercely.
