Why Change?

Title: Why Change?
Author: Ralph Beard
Year: 1164
Subject: Why our civilization should change to dozenal.

The first Editor of the Duodecimal Bulletin parallels the duodecimal number base with the adoption of Hindu-Arabic numerals and positional notation in medieval Europe. Dozenal must replace decimal, because the latter has “not enough factors” in comparison to dozenal.
