Eudoxus
(BC 408  355)
Born in 408 B.C. in Cnidus. He was a Greek geometer and astronomer.
Eudoxus studied at Plato's Academy and was a student of Archytas
of Tarentum. He spent over a year in Egypt and then, on his return,
established a school that competed with Plato. There is ample
evidence to suggest that Eudoxus had little respect for Plato's
analytic ability.
Eudoxus proposed a heliocentric system for the solar system; a
very important contribution. Other important contributions were
to the theory of proportion, where he made a definition of equal
ratios similar to cross multiplying, and early work on integration
with the theory of exhaustion. Eudoxus also devised a theory of
planets carried on glassy spheres that were nested around the
Earth in mountings like compass gimbals: rotations on these explained
observed motions.
The kampyle curve was studied by Eudoxus also in relation to the
classical problem of duplication of the cube. Eudoxus found formulas
for measuring pyramids cones and cylinders. Books V and XII of
Euclid's Elements are attributed to Eudoxus by some experts. In
355 B.C. Eudoxus died in Cnidus.
