Eudoxus of Cnidus (born c. 395 – 390 B.C. Eudoxus was the rst Greek to make a map of the stars. Each sphere is attached to a larger sphere through a pole. 408 BC) A pupil of Plato, Eudoxus elaborated a geocentric model composed of crystalline spheres, incorporating the Platonic ideal of uniform circular motion. Eudoxus of Cnidus. The Sun, the Moon, the … ), a Greek astronomer and mathematician, was the first to propose a model of the universe based on geometry. His model composed of 27 concentric spheres with Earth as the center. System of 27 Spheres: 1 for the fixed stars 3 each for the Sun and Moon 4 each for the 5 planets Biographical highlights: Eudoxus was born in Cnidos, on the Black Sea. One of Plato’s pupils, the mathematician Eudoxus of Cnidus, whose skill at geometry was equal to his master’s demands, perfected the Platonic model of the cosmos by explaining the apparent motion of the planets in relation to combinations of uniform, circular movements – … 56 He studied mathematics with Archytus in Tarentum. (about 395–342 bc).A Greek mathematician and astronomer, Eudoxus of Cnidus contributed to the identification of constellations and thus to the development of astronomy in ancient Greece.He also established the first sophisticated model of planetary motion and made important contributions to geometry.. Eudoxus was born around 395–390 bc in Cnidus, Asia Minor (now in Turkey). Eudoxus (c. 400 B.C.) Eudoxus founded mathematical astronomy when he created the first mathematical model of the universe, expressing the movement of the heavens in the language of spherical geometry. His model composed of 27 concentric spheres with Earth as the center. The Sun, the Moon, the planets, and the fixed stars have spheres. ), a Greek astronomer and mathematician, was the first to propose a model of the universe based on geometry. developed by Eudoxus of Cnidus In physical science: Ancient Middle Eastern and Greek astronomy He developed a theory of homocentric spheres, a model that represented the universe by sets of nesting concentric spheres the motions of which combined to produce the planetary and other celestial motions. Eudoxus of Cnidos (b. He studied medicine with Philistium on Sicily. Eudoxus’ Model. Eudoxus and astronomy Eudoxus elaborated a geocentric model composed of crystalline spheres, incorporating the Platonic ideal of uniform circular motion. is the greatest of the ancient mathematicians, surpassed only by Archimedes -- but later. 3A Greek orator and statesman who took up rhetoric as a profession. Eudoxus of Cnidus (born c. 395 – 390 B.C. This model is known as a geocentric model – often named Ptolemaic model after its most famous supporter, the Greco-Roman astronomer Ptolemy. Eudoxus made momentous advances in mathematics; he was the world’s greatest mathematician before Archimedes. As to his teachers, we know that he travelled to Tarentum, now in Italy, where he studied with Archytas who was a follower of Pythagoras.The problem of duplicating the cube was one which interested Archytas and it would be reasonable to suppose that Eudoxus's interest in that problem was stimulated by his teacher. Biography Eudoxus of Cnidus was the son of Aischines. The geocentric model establishes that the earth is at the centre of the Universe and from this point on, the entire universe, the stars, planets and the stars, including the sun, rotates. Eudoxus, one of Plato's pupils, proposed a universe where all objects in the sky sit on moving spheres, with the Earth at the centre.
