Ancient Egyptian metal tool kit is well described and it consisted of metal blades of chisels, adzes, axes, saws and drills, used for the work on various types of wood and stones. [18] Also, the ancient Egyptians were apparently using core drills in stonework at least as long ago as the Fourth Dynasty , probably made of copper or arsenical ...
The Archimedes' screw, also known as the Archimedean screw, hydrodynamic screw, water screw or Egyptian screw, [1] is one of the earliest hydraulic machines named after Greek mathematician Archimedes who first described it around 234 BC, although the device had been used in Ancient Egypt. [2] It is a reversible hydraulic machine, and there are ...
These machines are the inclined plane, the wedge, and the lever, which allowed the ancient Egyptians to move millions of limestone blocks which weighed approximately 3.5 tons (7,000 lbs.) each into place to create structures like the Great Pyramid of Giza, which is 481 feet (147 meters) high. [17]
Egyptian pyramid construction techniques are the controversial subject of many hypotheses. These techniques seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these ...
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!

The lever was also used in the shadoof water-lifting device, the first crane machine, which appeared in Mesopotamia circa 3000 BC, [4] and then in ancient Egyptian technology circa 2000 BC. [6] The earliest evidence of pulleys date back to Mesopotamia in the early 2nd millennium BC, [7] and ancient Egypt during the Twelfth Dynasty (1991-1802 BC ...
The history of technology is the history of the invention of tools and techniques by humans. Technology includes methods ranging from simple stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word techne, meaning art and craft, and the word logos ...
Metal production in the ancient Middle East. The metals of antiquity are the seven metals which humans had identified and found use for in prehistoric times in Africa, Europe and throughout Asia: [1] gold, silver, copper, tin, lead, iron, and mercury. Zinc, arsenic, and antimony were also known during antiquity, but they were not recognised as ...
