Advanced Level Pure Mathematics (Physical Science Texts) Book

A comprehensive history of Greek mathematics, divided by topics -- after a couple of introductory chapters on terminology, numerals and notation, it deals with Pythagorean arithmetic, the beginnings of geometry, Pythagorean geometry, the elements of geometry before Plato, math in Plato, the elements between Plato and Euclid, more advanced problems, and ends up with Euclid. Much of Greek geometry is just algebra in disguise. This first book covers the theory of incommensurables (irrationals) and the discovery of conic sections. It seems the Greeks were more advanced in some areas than I was aware of.
