A fact or two:
Any and every type of calculation which can be carried out in base ten can be carried out in base twelve or in any other base one might choose. "Points", "logs", slide-rules and push-button calculators are not peculiar to base ten, but are employed also by other bases, though admittedly not as extensively.
The merits of base twelve are due to the great factorability of the number twelve, the next really useful number being sixty, but sixty is rather too large for an every-day number base. Ten is unsatisfactory because its factors 2 and 5 include the prime 5 which in turn is not as useful as the prime 3 (though one professor of mathematics complained that I was not being really fair to the number 5 when I said this ... ). The dozen, and the dozen dozen, or gross, have shown their usefulness in packing and packaging over many, many years.
And will Mankind be interested enough to listen? or kind enough? We live in hope…
Aye, it′s counting, Jim, but not as we know it…
But just consider, for a moment ... What would happen, if ...?
Now there's a thought to boggle the mind... Suppose we changed the number base, just like that, what would tomorrow be like? For the implications, have a look at "Splash!".
So it′s nothing but base twelve here?
No, there's more, all mathematical, - other bases, number puzzles, units of measure (including historical), important essays, some metric-bashing, - and more to come as we develop different areas.
Magazine: We no longer publish a regular Newsletter or magazine - all new work appears either here or in the Dozenal Forum, which has attracted many new members with valuable ideas and comments. Our pages here average some two hundred visits each week. The last Dozenal Journal we sent out to members is available for download: Journal as are other digital editions of previous publications.
Issues of the Journal and previous DSGB magazines are being digitized and several are available for download. This, and revision and editing of DSGB website pages, will be occupying us for some time.
With effect February 2017 Shaun Ferguson retires from the posts of Secretary and Treasurer of the DSGB, and Bryan Parry takes over.
Most recent changes (August 2017): some editing and tidying of the "Basics" section, "Dozenite system" by Pasumarty added;More DSGB magazines digitised; New dozenal url references, Dozenal apps from the DSA. "Splash" section revised and extended; New dozenal clock for your desktop (java) - in Applications; "Hamburg Musical Notation" added to application section; TGM (pdf archive of first edition); revised TGM booklet (pdf: spellings, spacing, general corrections), DSGB Newscast Archives added (Magazines in pdf format). These pdf versions of the Duodecimal Newscast have been produced for us by the DSA from scans of the original magazines. More will be published here in due course.
In Memoriam - an obituary for Arthur Whillock
Our Information Secretary, Arthur Whillock, died on Saturday 27th May 2006.
a few words about us...
The DSGB, The Dozenal Society of Great Britain (founded 1959) and the DSA, The Dozenal Society of America (founded 1944) are separate organisations with a common aim: to draw attention to the advantages of the Dozen (or twelve-based) system for numeration and measurement. We consider that the decimal system is inadequate and of limited competence in many aspects of numeration. Decimals handicap the teaching of arithmetic and so inhibit understanding of the physical world and the decimal system is unable to express in simple terms the common proportions by which we order our practical and economic activities.
Membership of the Societies is open to all who have an interest in the development of arithmetic and measuring systems as vital tools for our everyday affairs and in promoting a clearer understanding of the ways in which the physical world is defined and ordered. By advocating the adoption of a more flexible numbering system for both scientific and general use we are also supporting the opinions of many philosophers and mathematicians, both past and present.
