Also known as Loculus of Archimedes or Archimedes' Box, [89] this is a dissection puzzle similar to a Tangram, and the treatise describing it was found in more complete form in the Archimedes Palimpsest. Archimedes calculates the areas of the 14 pieces which can be assembled to form a square.
The Archimedes Palimpsest is a parchment codex palimpsest, originally a Byzantine Greek copy of a compilation of Archimedes and other authors. It contains two works of Archimedes that were thought to have been lost (the Ostomachion and the Method of Mechanical Theorems) and the only surviving original Greek edition of his work On Floating ...
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.
Following Archimedes's estimate of a myriad (10,000) grains of sand in a poppy seed; 64,000 poppy seeds in a dactyl-sphere; the length of a stadium as 10,000 dactyls; and accepting 19mm as the width of a dactyl, the diameter of Archimedes's typical sand grain would be 18.3 μm, which today we would call a grain of silt. Currently, the smallest ...
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 ...
Archimedes' heat ray, a device that Archimedes is purported to have used to burn attacking Roman ships during the siege of Syracuse. [1] Claw of Archimedes, purportedly a sort of crane used to drop an attacking Roman ship partly down in to the water during the siege of Syracuse. [3] Polybolos, an ancient Greek repeating ballista.

Archimedes then considered rotating the triangular region between y = 0 and y = x and x = 2 on the x-y plane around the x-axis, to form a cone. [1]: 18–21 The cross section of this cone is a circle of radius () = and the area of this cross section is
