Greek mathematician, engineer, and physicist. Among the most important intellectual figures of antiquity, he discovered formulas for the area and volume of various geometric figures, applied geometry to hydrostatics and mechanics, devised numerous ingenious mechanisms, such as the Archimedean screw, and discovered the principle of buoyancy.
Greek mathematician, engineer, and inventor. He made numerous mathematical discoveries, including the ratio of the radius of a circle to its circumference as well as formulas for the areas and volumes of various geometric figures. Archimedes created the science of mechanics, devising the first general theory of levers and finding methods for determining the center of gravity of a variety of bodies. He also invented an early type of pump called the Archimedian screw.
Ancient Greek Ἀρχιμήδης (Arkhimēdēs).
- The word parabola was used by Archimedes, who was prior to Apollonius; but this may be an interpolation.
- Archimedes died at the capture of Syracuse by Marcellus, 212 B.C. In the general massacre which followed the fall of the city, Archimedes, while engaged in drawing a mathematical figure on the sand, was run through the body by a Roman soldier.
- As stated first by Archimedes, the principle asserts the obvious fact that a body displaces its own volume of water; and he utilized it in the problem of the determination of the adulteration of the crown of Hiero.
- If, therefore, the walls of the enclosure held the gas that is directly in contact with them, this equilibrium would be the actual state of affairs; and it would follow from the principle of Archimedes that, when extraneous forces such as gravity are not considered, the gas would exert no resultant force on any body immersed in it.
- The founder of the mathematical school was the celebrated Euclid (Eucleides); among its scholars were Archimedes; Apollonius of Perga, author of a treatise on Conic Sections; Eratosthenes, to whom we owe the first measurement of the earth; and Hipparchus, the founder of the epicyclical theory of the heavens, afterwards called the Ptolemaic system, from its most famous expositor, Claudius Ptolemaeus.
