  • Infectious Disease Modeling: Zombie Edition (PDF)Zombies are a popular figure in pop culture/entertainment and they are usually portrayed as being brought about through an outbreak or epidemic. Consequently, we model a zombie attack, using biological assumptions based on popular zombie movies. We introduce a basic model for zombie infection, determine equilibria and their stability, and illustrate the outcome with numerical solutions. We then refine the model to introduce a latent period of zombification, whereby humans are infected, but not infectious, before becoming undead. We then modify the model to include the effects of possible quarantine or a cure. Finally, we examine the impact of regular, impulsive reductions in the number of zombies and derive conditions under which eradication can occur. We show that only quick, aggressive attacks can stave off the doomsday scenario: the collapse of society as zombies overtake us all.[more inside]posted by Weebot at 11:34 PM - 15 comments

  • Cheap 3D printing has the potential to change the way we produce and consume objects in the same way the cheap PCs and the internet changed the way we produce and consume information. Once again it is hobbyists and university labs who are democratizing the technology. They are looking forward to the day when anyone can make designer bath fixtures, functional appliances, custom surgical implants, or even business opportunities at the click of a button.

    However some are warning that overly broad patents could derail the whole revolution. Even more worrisome is the prospect that existing IP law is completely unprepared for a future where the cost boundary between ideas and physical objects has crumbled. Will commercial interests demand a crack down on "pirated" printouts? Will Open Source manufacturing bring about a Star Trekian utopia? It's hard to predict what will happen when everything is commodified.
