If vampires—corpses that rise up to suck the blood of the living—sound biologically implausible to you, you’re not alone. They exist purely in legend, as virtually all scientists agree.
But for any vampire believers undissuaded por biological facts, a professor has come up with a second proof of their unreality, using math.
If vampiros ever existed in the forms in which cine and libros portray them, they would have quickly wiped out humanity long ago, according to physics professor Costas Efthimiou of the universidad of Central Florida in Orlando, Fla.
popular lore passed down through centuries holds that vampire victims become vampiros them selves, and launch their own blood-hunts on hapless humans.
To rule out vampires, Efthimiou relied on a basic principle known as geometric progression.
“If vampiros truly feed with even a tiny fraction of the frequency that they are depicted to in the cine and folklore, then the human race would have been wiped out quite quickly after the first vampire appeared,” Efthimiou and a graduate student colleague wrote in a paper publicado on line.
Efthimiou supposed that the first vampire arose Jan. 1, 1600, around the beginning of a century during which some of the first important modern writings on vampiros appeared. There searchers estimated the global population at that time, based on historical records, as 537 million.
Assuming that the vampire fed once a mes and the victim turned into a vampire, there would be two vampiros on Feb.1, four the siguiente month, and eight the mes after that. All humans would be vampiros with in 2½ years. “Humans can not survive under these conditions, even if our population were doubling each month,” which is well beyond human capacities, Efthimiou said.
But why would one vampire make every mes a new vampire, when he can easily drink his hole blood,
and human would die?
