SPEAKER:    Dr. Peter Ulrickson

TITLE:   Enumerating the Rationals with Adrastus

ABSTRACT: 

I will present a classification of ratio from Boethius's de institutione arithmetica and explain how it can be understood as an enumeration of the rationals. I will also connect this to David Fowler's ideas about the Euclidean algorithm in ancient conceptions of ratio, and the more recent development of the Stern-Brocot tree.

ORGANIZERS:    V. Bogdan (Catholic University), P. Kainen (Georgetown University), R. Kalpathy (Catholic University), and A. Levin (Catholic University).
