Re: А тогда...
Забавный вопросик вот цитатку нашел:
похоже что Аристотелю и Авиценне это было известно, а вот в средние века похоже была дыра.

Soldiers of Alexander the Great followed the advice of the celebrated Aristotle, to
boil their drinking water. In Persia, Avicenna (980-1046) indicated in Book ill of his
Canon that water may be rendered drinkable by evaporation and distillation, or simply
by boiling (14). The wisdom of these recommendations was acknowledged over the
ages, and was proved scientifically in 1776 by Spalanzani, who demonstrated that it was
impossible for 'spontaneous generation' of microorganisms to occur once the fluid they
lived in had been boiled for an hour (2). Previously, Joblot had demonstrated in 1718
35
that it was possible to sterilise an infusion of hay by boiling it for fifteen minutes and
then sealing the container (2).
