In short, the Antikythera Mechanism was a machine designed to predict celestial phenomena according to the sophisticated astronomical theories current in its day, the sole witness to a lost history of brilliant engineering, a conception of pure genius, one of the great wonders of the ancient world—but it didn't really work very well!
Depictions of wheeled wagons found on clay tablet pictographs at the Eanna district of Uruk are dated between 3700 and 3500 BC. [8] The lever was used in the shadoof water-lifting device, the first crane machine, which appeared in Mesopotamia circa 3000 BC, [9] and then in ancient Egyptian technology circa 2000 BC. [10]
Inventions that are credited to the ancient Greeks include the gear, screw, rotary mills, bronze casting techniques, water clock, water organ, the torsion catapult, the use of steam to operate some experimental machines and toys, and a chart to find prime numbers. Many of these inventions occurred late in the Greek period, often inspired by the ...
The grain-of-sand-sized placozoan has oceans of information
Air bubbles within a deep ice core drilled in Antarctica could reveal why Earth suddenly began to experience longer ice ages nearly 1 million years ago.
The screw pump is the oldest positive displacement pump. [1] The first records of a water screw, or screw pump, date back to Hellenistic Egypt before the 3rd century BC. [1] [3] The Egyptian screw, used to lift water from the Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation.
Human teeth were found, opening the possibility of genetic and isotopic analysis to provide information on the people who sailed the ship. Archaeologist Lorenz Baumer, overseeing the 2022 mission with the University of Geneva , described the Antikythera wreck as "an extremely rich site, the richest in the ancient world".
Archaeologists recently found the lost ruins of a ceremonial temple—covered in sand and 4,000 to 5,000 years old—in northwestern Peru. The excavation team first discovered the walls, and ...
