Short Summary
Eudoxus of Cnidus was an ancient Greek mathematician, astronomer, and philosopher, renowned for his significant contributions to mathematics and astronomy. He introduced the theory of proportions, a precursor to mathematical concepts developed by Euclid. Eudoxus is also known for his work in astronomy, particularly his development of the theory of celestial spheres, which influenced later astronomical models. His achievements laid the groundwork for advancements in both mathematics and astronomy, securing his place in history as a pioneering intellectual figure.
Early Life & Education
Eudoxus was born around 408 BC in Cnidus, an ancient Greek city located in modern-day Turkey. Little is known about his family background, but it is believed that he was born into a wealthy and influential family. He studied initially under Archytas and later moved to Athens, where he became a student of Plato. His education was further enriched by his travels to Egypt, where he studied with Egyptian priests and absorbed knowledge about mathematics and astronomy. These early influences shaped his intellectual pursuits and laid the foundation for his future contributions.
Career Highlights
Eudoxus's career was marked by significant accomplishments in both mathematics and astronomy. He is credited with the development of the theory of proportions, which became a central part of Euclidean geometry. In astronomy, Eudoxus proposed a model of celestial spheres that attempted to explain the complex motions of the planets. This model, although later superseded, was a critical step in the development of astronomical theories. Additionally, he founded a school in Cyzicus, where he disseminated his knowledge and continued to influence future generations of scholars.
