ArchimedesArchimedes of Syracuse (circa 287 BC - 212 BC), was a Greek mathematician, astronomer, physicist and engineer. DiscoveriesArchimedes is one of the greatest mathematicians of all time. He became a popular figure as a result of his involvement in the defense of Syracuse against the Roman siege in the First and Second Punic Wars. He is reputed to have held the Romans at bay with war engines of his design; to have been able to move a full-size ship complete with crew and cargo by pulling a single rope; to have discovered the principles of density and buoyancy while taking a bath (thereupon taking to the streets naked calling "eureka" - "I have found it!"); and to have invented the irrigation device known as Archimedes' screw. In creativity and insight, he exceeded any other mathematician prior to the European renaissance. In a civilization with an awkward numeral system and a language in which "a myriad" (literally ten thousand) meant "infinity", he invented a positional numeral system and used it to write numbers up to 1064. He devised a heuristic method based
ARCHIMEDESca. 287-212 B.C. Greek mathematician Archimedes is considered to be the greatest mathematician of the ancient world. He played a major role in the development „ of mathematics after Euclid, making significant contributions to geometry and physics. Archimedes is also remembered for several ingenious inventions. Life of Archimedes. Archimedes was born about 287 B.C. in the Greek colony of Syracuse on the island of Sicily. The son of an astronomer, Archimedes studied in Alexandria in Egypt, an important center of Hellenistic* culture. According to historians, Archimedes designed one of his most famous inventions while in Alexandria—a mechanical device for raising water from the Nile River into canals for the irrigation of nearby farm fields. Known as Archimedes’ screw, the device consisted of a screw-shaped spiral enclosed in a cylinder. When the bottom of the device was placed in water and the cylinder rotated, water traveled up the spiral and flowed out the top. Modern versions of Archimedes’ screw are still in use in some parts of Egypt. Copyright ©tiedame.pages.dev 2025 |
