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 by biological facts, a professor has come up with a second proof of their unreality, using math.
If Вампиры ever existed in the forms in which Фильмы and Книги portray them, they would have quickly wiped out humanity long ago, according to physics professor Costas Efthimiou of the университет of Central Florida in Orlando, Fla.
Популярное lore passed down through centuries holds that vampire victims become Вампиры 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 Вампиры truly feed with even a tiny fraction of the frequency that they are depicted to in the Фильмы 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 Опубликовано 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 Вампиры appeared. There searchers estimated the global population at that time, based on historical records, as 537 million.
Assuming that the vampire fed once a месяц and the victim turned into a vampire, there would be two Вампиры on Feb.1, four the Далее month, and eight the месяц after that. All humans would be Вампиры 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 месяц a new vampire, when he can easily drink his hole blood,
and human would die?
