Statistical Mechanics Finds Best Places To Hide During Zombie Apocalypse

HughPickens.com writes Eric Mack reports at Cnet that a team of researchers at Cornell University, inspired by the book "World War Z" by Max Brooks, have used statistical-mechanics to model how an actual zombie outbreak might unfold and determined the best long-term strategy for surviving the walking dead: Head for the hills. Specifically, you should probably get familiar now with the general location of Glacier National Park so that when it all goes down, you can start heading in that direction. The project started with differential equations to model a fully connected population, then moved on to lattice-based models, and ended with a full US-scale simulation of an outbreak across the continental US. "At their heart, the simulations are akin to modeling chemical reactions taking place between different elements and, in this case, we have four states a person can be in--human," says Alex Alemi, "infected, zombie, or dead zombie--with approximately 300 million people."

Alemi believes cities would succumb to the zombie scourge quickly, but the infection rate would slow down significantly in more sparsely populated areas and could take months to reach places like the Northern Rockies and Glacier National Park. "Given the dynamics of the disease, once the zombies invade more sparsely populated areas, the whole outbreak slows down--there are fewer humans to bite, so you start creating zombies at a slower rate," Alemi says. Once you hit Montana and Idaho, you might as well keep heading farther north into the Canadian Rockies and all the way up to Alaska where data analysis shows you're most likely to survive the zombie apocalypse. The state with the lowest survival rate? — New Jersey. Unfortunately a full scale simulation of an outbreak in the United States shows that for `realistic' parameters, we are largely doomed.

One smart human with 30 minutes to prepare makes a spear and scares off a lion, wolf, or even a bear. Why? Because we are some sneaky, devious, son's of bitches that outwit enemies.

    4) So please tell me how in the real world a single zombie can infect all the rest of us?

    It simply can NOT happen. The zombies will have surprise on their side for maybe 10 hours - and that's assuming it turns zombie close to nightfall. But even then, the surprise won't last long.

    Come the day after the zombie outbreak ends, they will all be dead. They will NEVER take an entire city. At best they might take over a small town/rural community before word gets out, and humans arm ourselves with spears, axes, shotguns, torches, etc. Yeah, a few new zombies would be created after the surprise wore off, but if 1 human kills on average 3 zombies before they themselves become a zombie, then the number of zombies would drop like a bar of lead dropped out of an airplane.

The fact that zombies need contact and a shotgun simply needs proximity will also tip the balance in favor of the humans.

    While I enjoy the genre, I find that the "rules" of zombie apocalypse seem designed to limit the ability to humans to fight back by imposing arbitrary limits on the effectiveness of weapons.

    Brooks quickly discounts the effectiveness of military weapons like cluster munitions, Gatling guns and other kinds of weapons designed to put a large amount of shrapnel or projectiles into an area quickly. Even if it didn't result in killing of an entire horde, I would expect it to kill a large number and greatly reduce the threat of most of them by seriously degrading their mobility through damage to their ability to walk or move.

    I'd like to see a Mythbusters episode where they take a 7.62mm Gatling gun and fire it into a simulated zombie horde at average head height to see what kind of damage it would do. It's probably beyond practicality to setup that many targets, but it would be an interesting simulation nonetheless.

    I think the simplest way to deal with a horde would be a minor adaption of a machine designed to clear minefields -- the demining flail. These slightly resemble a combine bolted onto the front of a tank, with the "combine" being basically a bunch of steel weights on the ends of chains designed to beat on the ground to set off mines.

    It's not hard to imagine a much lighter weight device (since zombies don't explode) spinning 5 pound weights in the air. It would completely pulverize zombies and turn clearing zombie hordes into something akin to mowing the grass.

      If a zombie can move at human walking speed, they can advance at 270 feet per minute, so a battery of 18 miniguns, allowing for 6 firing concurrently, could kill the horde faster than they can advance. Probably fewer guns would be necessary as the dead bodies would slow the advance as they stacked up.

      And that's just an example of a single type of gun. The Mk 19 grenade launcher's standard ammo has a kill radius of 5 meters. Call that an effective disablement (outright dead or unable to move even if alive) radius for zombies of 2 meters, and a single round can stop 50 zombies in a fairly dense pack.
