Well, here we go, then: physicists have proved that vampires don't exist:
Two physicists have published an academic paper where they demonstrate, by virtue of geometric progression, that vampires could not exist, since they would almost immediately deplete their entire food supply (a.k.a, all of us).
Very droll, you might think. But no, they are perfectly serious:
Efthimiou and Gandhi conduct a thought experiment: Assume that the first vampire appeared on January 1, 1600. At that time, according to data available at the U.S. Census website, the global population was 536,870,911. Efthimiou and Gandhi calculate that, once the Nosferatu feeding frenzy began, the entire human race would have been wiped out by June 1602 (thus forever changing the course of history by preventing the invention of the slide rule eighteen years later).
The physicists note:Another philosophical principal related to our argument is the truism given the elaborate title, the anthropic principle. This states that if something is necessary for human existence, then it must be true since we do exist. In the present case, the nonexistence of vampires is necessary for human existence. Apparently, whomever devised the vampire legend had failed his college algebra and philosophy courses.
Oooh, snap! But, this gauntlet had been barely thrown down before it invited a rebuttal from mathematician Dino Sejdinovic. In his article, "Mathematics of the Human Vampire Conflict" (Math Horizons, November 2008) Sejdinovic faults Efthimiou and Gandhi's logic, since they have not "accounted for the birth-rate of non-vampires and death-rate of vampires (actually the death-death-rate since they are already dead, but when they die again they should stay dead but stop being living) due to close encounters with stakes, garlic and holy water." Moreover, "vampires are presented exclusively as greedy consumers: a rational strategy of managing their human resources is not considered."
Here, Sejdinovic cites the pioneering research conducted by Austrian mathematicians Richard Hartl and Alexander Mehlmann, who published the landmark 1982 paper, "The Transylvanian Problem of Renewable Resources," later followed up by "Cycles of Fear: Periodic Bloodsucking Rates for Vampires" (Journal of Optimization Theory and Application, December 1992). Hartl and Mehlmann argue that vampires would never be stupid enough to deplete their entire food supply, and by applying the Hopf-Bifurcation Theorem (don't ask), they demonstrate how vampires can adopt an optimal "cyclical bloodsucking strategy."
Seriously. And yet:
However, there is a serious flaw in the Hartl and Mehlmann model: The assumption that human beings would be docile prey. Their research provoked an outraged response from economist Dennis Snower, who in his article "Macroeconomic Policy and the Optimal Destruction of Vampires" (The Journal of Political Economy, June 1982), declared:One wonders what conceivable interest the authors could have had in helping vampires solve their intertemporal consumption problem. The implicit assumption of the Invisible Hand (or Fang)-whereby vampires, in pursuing their own interests, pursue those of human beings as well-is of questionable validity. The study by Hartl and Mehlmann is not concerned with the macroeconomic implications of blood-sucking behavior modes. Nor does it consider the policy instruments whereby human beings can protect themselves from vampires. Instead, humans are modeled as passive receptacles of blood whose cultivation and harvest are left to vampire discretion.
So, we can relax. The world's finest minds have looked at this worrying problem and proved that we're not going to be eaten by vampires. You don't need to hope that Blade finds you before the suckheads do.
Isn't that a relief?
