The DSA enters the age of 9/11 still producing exploratory articles. Editor Jay Schiffman pens rigorous mathematical studies of hexadecimal divisibility tests, and illustrates how Wolfram Mathematica is an asset to conversion among the number bases. A strong draft of anti-metrication sentiment materializes in Volumes 41; through 43;. It seems the culture wars of the age have found their way into the perceptions of Euro-government’s drive to decimalize all nations. Often couched in the guise of “Big Brother” style “fascism”, government-mandated compliance with SI-metric units begins to be seen as an affront to private liberties in Britain. There is a "Metric Martyr", letters howling against forced abandonment of traditional measure, questioning whether Europe really is truly "metric". *The Duodecimal Bulletin* considers other number bases “ecumenically” in articles about Mayan near-vigesimal, Prof. Schiffman’s hexadecimal, and sexagesimal errors in Sumerian dynastic lists. A couple articles look back on the founding of the Society. Some favorite articles are reprinted, such as Prof. Malone’s “Eggsactly a Dozen” (A Simple Approach to Dozenal Counting) and J. Halcro Johnston’s “The Reverse Notation”.
