    Roman water engineering

    An interesting story about river Ljubljanica, Ljubljana Marshes (Slovenia), and the Romans. How they first straightened the river channel, and then moved the whole river closer to a marble quarry. Bonus: photos were taken from a kite :)

    Access to water or drinks while travelling?

    I'm an avid Dungeon Master with a love of history. Although I like magic, I also like to put my players to the hardships of life in more medieval times. However, I came upon a question that I couldn't find an answer to: how did people in medieval times have access to water or drinks? Did they...

    Evaporation

    Would anyone have any information on pre-scientific revolution theories attempting to explain the cause for evaporation? Or could someone point me towards reading that might lead to some? It could be from any period, ancient to medieval. I imagine there must be some colourful ones. Thanks!

    Is Putin's strategy for control of a warm water port?

    As the rusty Russian tubs scoot past Dover on Trafalgar Day the Brit press are going into meltdown that those dastardly commies are daring to twitch the lion's tail. Naturally this is absurdly biased reporting to make the Russians out as the bad guys, if it were the French or Spanish it...

    The pre-modern Chinese and clean water

    It occurs to me that one thing is still a mystery to me--how did people in pre-modern Chinese cities get clean water? Was it all from wells? Rivers?

    Strong evidence of liquid water on the surface of Mars has been found: "Liquid water exists on Mars, boosting hopes for life there, NASA says" | CNN It seems to be a very strong brine, certainly not fresh water, but this is still an intriguing finding.

    Logistics of water in the 19th century

    How did armies during the mid to late 19th century, (particularly Russians in the Crimean War), keep their armies hydrated?

    Water Fluoridation & facts

    There are only two sides in this issue: the pros/pushers and the "antis"/nons. The pros claim that they fluoridate water because of "(increased) incidence of (childrens) tooth decay". They claim that it is "safe, cheap, and effective". They claim that unfluoridated places have more toothdecay...

    An Almost Empty Water Bottle...

    So a water bottle that has about an ounce or so left of water is capped and discarded. Perhaps it is thrown into the wilderness as the owner no longer desires to carry it throws it away. Perhaps it makes it to a landfill and is eventually buried. How long does it take for that plastic to...
