5 stories mention Eudoxus of Cnidus on DeadlyCurious.
Eudoxus of Cnidus proposed in the 360s BC that the apparent motions of the planets could be explained by a system of 27 concentric rotating spheres centred on the Earth. Aristotle expanded the model to 55 spheres. The framework substantively defined European cosmology until Tycho Brahe.
Read the story →Hippocrates of Chios was a Greek geometer of the late 5th century BC — not the famous physician of Cos. He was the first European mathematician to compute the exact area of a region bounded by curves, an achievement that opened the path Eudoxus and Archimedes would later complete with the method of exhaustion.
Read the story →Plato's Academy was founded around 387 BC and closed by Justinian's edict in 529 AD. For most of that nine-century period the Academy was the institutional core of Greek mathematical and astronomical teaching — the lineage that produced Eudoxus, Aristotle, Theaetetus, and most of the substantively classical Greek mathematical tradition.
Read the story →Before Eudoxus, Greek mathematicians could prove statements about simple shapes. Eudoxus invented the method that let them prove statements about curves.
Read the story →He used balance points to discover the volumes of curved solids, then proved them with strict geometry. The Greeks called it forbidden. He called it the Method.
