Key words and phrases. Greek mathematics, pre-Euclidean mathematics, Euclid* s Elements, classification of incommensurable magnitudes, proportion theory, 'Book five lays out the work of Eudoxus on proportion applied to commensurable and incommensurable magnitudes.' More example sentences. 9 Apr 2019 'Incommensurability' is a term that philosophers of science have borrowed from mathematics. Two mathematical magnitudes are said to be A magnitude, e.g. the diagonal of a square, is neither “rational” nor “irrational” in itself: it is either commensurable or incommensurable with another magnitude.

For example, the numbers 3 and 2 are commensurable because their ratio, 3/2, is a rational number. The numbers 3 {\displaystyle {\sqrt {3}}} and 2 3 {\displaystyle 2{\sqrt {3}}} are also commensurable because their ratio, 3 2 3 = 1 2 {\textstyle Magnitudes commensurable with the same magnitude are also commensurable with one another.

## THE PRE-EUCLIDEAN THEORY OF INCOMMENSURABLE MAGNITUDES The Euclidean theory of incommensurable magnitudes, as preserved in Book X of the Elements, is a synthetic masterwork. Yet there are detect

Also crucial to Zeno’s work with incommensurable magnitudes was the fundamental focus on deductive reasoning that resulted from the foundational shattering of earlier Greek mathematics. The realization that some basic conception within the existing theory was at odds with reality necessitated a complete and thorough investigation of the axioms and assumptions that underlie that theory.
