Abstract

The notion of an infinitesimal number has been used in mathematical arguments since before the time of Archimedes, some 2200 years ago. We understand infinitesimals in terms of a scale set by ordinary numbers. For a positive number to be infinitesimal, it must be greater than 0 and yet smaller than any positive number you might write using a decimal expansion. No matter how many zeros you start with in that expansion, a positive infinitesimal number will be still smaller.
