## -0408 – Eudoxus – bio

Eudoxus was born around -0408 in Cnidus (now in Turkey) as a Greek and was a mathematician and an astronomer. He learned mathematics from Archytas, astronomy in Egypt, philosophy from Plato and was a teacher to Aristotle. Eudoxus created the first concept of spherical astronomy and planetary motion. He worked on the theory of proportion, which compares ratios of lengths. His work was later documented by Euclid and Archimedes.

Eudoxus developed Antiphon’s “method of exhaustion” which became a precursor to integral calculus. Euclid used this technique and then Archimedes expanded it.
