Unlike his inventions, Archimedes' mathematical writings were little known in antiquity. Alexandrian mathematicians read and quoted him, but the first comprehensive compilation was not made until c. 530 AD by Isidore of Miletus in Byzantine Constantinople , while Eutocius ' commentaries on Archimedes' works in the same century opened them to ...
The Claw of Archimedes (Ancient Greek: Ἁρπάγη, romanized: harpágē, lit. 'snatcher'; also known as the iron hand ) was an ancient weapon devised by Archimedes to defend the seaward portion of Syracuse 's city wall against amphibious assault .
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.
A screw turbine at a small hydro power plant in Goryn, Poland. The Archimedean screw is an ancient invention, attributed to Archimedes of Syracuse (287–212 BC.), and commonly used to raise water from a watercourse for irrigation purposes.
Archimedes' heat ray: is a device that Archimedes is purported to have used to burn attacking Roman ships during the Siege of Syracuse (c. 213–212 BC). It does not appear in the surviving works of Archimedes and is described by historians writing many years after the siege.
Significant theoretical contributions were made by notables figures like Archimedes, Johann Bernoulli and his son Daniel Bernoulli, Leonhard Euler, Claude-Louis Navier and Stokes, who developed the fundamental equations to describe fluid mechanics. Advancements in experimentation and computational methods have further propelled the field ...
Clements took some shots of the girls modeling clothes from her neighbor's children's boutique on an old Nikon camera, and reached out to the industry contacts she made when they started 7 years ago.
Archimedes may have used mirrors acting collectively as a parabolic reflector to burn ships attacking Syracuse. Archimedes is purported to have invented a large scale solar furnace, sometimes described as a heat ray, and used it to burn attacking Roman ships during the Siege of Syracuse (c. 213–212 BC). It does not appear in the surviving ...
