That water clarity is an engineering decision, and the math behind it is wilder than the video.

Roman aqueducts ran on gravity alone. No pumps, no pressure systems. Engineers carved channels with a gradient so shallow it borders on absurd. The Pont du Gard in southern France drops 2.5 centimeters over 275 meters. That's roughly the thickness of a coin over the length of three football fields. They surveyed that accuracy with plumb lines and wooden leveling instruments.

The clarity you're seeing is a direct product of flow velocity. Too steep and the water erodes the channel walls, picks up sediment, turns brown. Too flat and it stagnates. Roman engineers targeted a slope of about 20 centimeters per kilometer, which kept the water moving fast enough to stay fresh but slow enough to stay clear. Before the water reached the city, it passed through multi-chamber settling tanks where velocity dropped near zero. Suspended particles sank. Clean water flowed out the top into the next chamber. Repeat three or four times.

Pliny specified the minimum slope in writing. Vitruvius published the exact mortar ratio for hydraulic cement: one part lime to two parts volcanic ash for underwater work. The pozzolana from Pozzuoli reacted with water to form a calcium-aluminum-silicate compound that actually gets stronger the longer it sits submerged. Modern concrete degrades in water. Roman concrete bonds with it.

Scale the whole system and it gets harder to process. Eleven aqueducts fed Rome at its peak. Combined output: roughly 1 million cubic meters of water per day. That works out to about 250 gallons per person for a city of one million. Modern New York delivers about 125 gallons per person per day. Ancient Rome had access to double the per capita water supply of the largest city in the United States, running entirely on slope and stone.

The Trevi Fountain in Rome is still fed by one of them. Two thousand years, same source, same gravity, same water.

this was so sweet. Stephen Colbert just ended his final episode of The Late Show while singing "Hello, Goodbye" with Paul McCartney. his family and the show's crew then joined them on stage before Paul turned off the lights to the Ed Sullivan Theater

Cyprus continues its fight against February’s foot and mouth outbreak.

Via the #EUCivilProtection Mechanism, the EU has deployed #rescEU supplies - disinfectants, PPE, coveralls, masks & more - to help curb the spread.

At this point, just give him a “Super Nobel Peace Prize for the Most Peace,” a coloring book of Greenland, so we can all move on with our lives.

Being a European today basically means having a pretty excellent day until around 5 pm when the White House starts posting the dumbest shit you've ever had the misfortune to read.

Every. Damn. Day.

Whataboutism is annoying, but the degree of double standards in European reactions to Trump plans for Gaza & Ukraine is staggering. Even with all the caveats - still biblical atrocious hypocrisy. Feeling v uncomfortable as a European (let alone a cypriot) https://t.co/KKVKzXAjF0

Ξέρει κανένας γιατί έκλεισε το Κέντρο Εξυπηρέτησης του Πολίτη στην Μακαρίου Λευκωσίας; Χάος στην Έγκωμη. Surely the capital needs more than one?
