The Evolution of the Euclidean Elements A Study of the Theory of Incommensurable Magnitudes and Its Significance for Early Greek Geometry
The present work has three principal objectives: (1) to fix the chronology of the development of the pre-Euclidean theory of incommensurable magnitudes beginning from the first discoveries by fifth-century Pythago reans, advancing through the achievements of Theodorus of Cyrene, Theaetetus, Archyta...
