It’s fun watching historical documentaries on Youtube.
There are various people who create satisfied in subjects that interest them, plus world history is no exception.
One of my most cherished Youtube satisfied creators is a world history instructor at a big state college. As a way to generate an additional income stream, she makes videos on many of the subjects that she covers in her college courses. In doing so, she takes high-priced information plus gives it to the masses for free, particularly for those who simply can’t afford college. There’s another channel that I watch which is made by a comparative religion instructor from a different college. The channel that has absolutely been the most informative to me thus far is focused on climate change, indoor climate control, plus the effects of meteorology on people plus their environments. The people who run this Youtube channel made a documentary recently about historical examples of indoor climate control, plus I was shocked to learn that Ancient Egyptians discovered evaporative air cooling thoUSAnds of years ago! They hung wet reeds in open windows at night; as hot air would enter from outside plus dry the reeds, the evaporating water would lower the temperature of the wind current. In addition to evaporative cooling, there were sites in Ancient Rome where water from the aqueducts was routed into channels that would encircle homes of the wealthy plus elite. The cold water would create a cooling effect for the tenants inside the building. Nowadays you have the same logic being used in hydronic heating systems, although the water is purely used for heating plus not for indoor cooling.
