Archimedes of Syracuse [a] (/ ˌ ɑːr k ɪ ˈ m iː d iː z / AR-kim-EE-deez; [2] c. 287 – c. 212 BC) was an Ancient Greek mathematician, physicist, engineer, astronomer, and inventor from the ancient city of Syracuse in Sicily. [3]
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: 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.
Historical writings suggested that Archimedes used “burning mirrors” to start anchored ships on fire during the siege of Syracuse from 214 to 212 BC. “Archimedes was so ahead of his time ...
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 ...
Syracuse was a colony of Corinth and the home of Archimedes, and the Antikythera Mechanism Research Project argued in 2008 that it might imply a connection with the school of Archimedes. [9] It was demonstrated in 2017 that the calendar on the Metonic Spiral is of the Corinthian type, but cannot be that of Syracuse. [44]
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. In 1819 the French engineer Claude Louis Marie Henri Navier (1785–1836) suggested using the Archimedean screw as a type of water wheel.
The first steam cannon was designed by Archimedes during the Siege of Syracuse. [1] Leonardo da Vinci was also known to have designed one (see the Architonnerre). The early device would consist of a large metal tube, preferably copper due to its high thermal conductivity, which would be placed in a furnace. One end of the tube would be capped ...
