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 works of Archimedes and there is no contemporary evidence for it, leading to modern scholars doubting its existence.
Archimedes before his death with a Roman soldier – copy of a Roman mosaic from the 2nd century. Marcus Claudius Marcellus had ordered that Archimedes, the well-known mathematician – and possibly equally well-known to Marcellus as the inventor of the mechanical devices that had so dominated the siege – should not be killed. Archimedes, who ...
Archimedes' investigation of paraboloids was possibly an idealization of the shapes of ships' hulls. Some of the paraboloids float with the base under water and the summit above water, similar to the way that icebergs float. Of Archimedes' works that survive, the second book of On Floating Bodies is considered his most mature work. [6]
The purported device, sometimes called "Archimedes' heat ray", has been the subject of an ongoing debate about its credibility since the Renaissance. [58] René Descartes rejected it as false, while modern researchers have attempted to recreate the effect using only the means that would have been available to Archimedes, mostly with negative ...
English: Summary of an Archimedes heat ray. In practice, many more mirrors than shown would be needed, and the results may have been merely soldier sweat, temporary blindness, and confusion rather than fire. The mirrors may have consisted of polished metal and had peep-holes drilled in the middle for use in aiming.
In ancient Greek geometry, the Ostomachion, also known as loculus Archimedius (from Latin 'Archimedes' box') or syntomachion, is a mathematical treatise attributed to Archimedes. This work has survived fragmentarily in an Arabic version and a copy, the Archimedes Palimpsest , of the original ancient Greek text made in Byzantine times.
