Donations 2. For Sale -Calendars for 11EE now available! 3. Dozenal News -Dozenal library for Haskell programming -Debate on Dozenal Feasibility -Proofwiki: An online encyclopedia of proofs -Video Proof: The Sum of All Positive Integers 4.

Backmatter ============================================================ = DONATIONS = ============================================================ Members, please remember that while dues are no longer required for membership, we still rely on the generosity of members to keep the DSA going. Donations of any amount, large or small, are welcome and needed. A donation of $10; ($12.) will procure Subscription membership, and entitles the payer to receive both a digital and a paper copy of the _Bulletin_ if requested. Other members will receive only a digital copy. To invoke this privilege, please notify the Editor of the Bulletin, Mike deVlieger, at mdevlieger@dozenal.org As members know, we are a volunteer organization which pays no salaries. As such, every penny you donate goes toward furthering the DSA's goals. It may be worth considering a monthly donation; say, $3, or $6, or whatever seems reasonable to you. This can be set up quite easily with Paypal or WePay, both of which are available at our web site. Of course, if you prefer to donate by check, you may send them to our worthy Treasurer, Jay Schiffman, payable to the Dozenal Society of America, at: Jay Schiffman 604-36 South Washington Square, #815 Philadelphia, PA 19106-4115 ----------------------Member Benefits----------------------- Chief among the benefits of membership, aside from the knowledge of supporting the DSA's mission, is receipt of _The Duodecimal Bulletin_. In addition, however, members also receive (digitally) a membership card containing their vital member information and a monthly calendar with dozenal numbers, containing suitable and educational dozenal quotations and graphics, laid out for wall display. To receive these, please notify us that you'd like to receive them: Contact@dozenal.org ============================================================ = FOR SALE = ============================================================ We are excited to announce the availability of calendars for next year, 11EE! The DSA is pleased to offer the following for sale. These are all either at cost, or the proceeds go to the Society. Wall Calendar for 11EE, coiled binding $10.05 Weekly Planner for 11EE $8.29 TGM: A Coherent Dozenal Metrology $8.00 Prices are, unfortunately but by necessity, in decimal. To find these works, simply go to: http://www.lulu.com/shop/shop.ep and enter the appropriate terms. E.g., searching for "11EE" will turn up these calendars and the planner; searching for "TGM dozenal" will turn up the TGM book. We hope to offer other titles, and even some other items (such as dozenal clocks and the like), in the near future. ============================================================ = DOZENAL NEWS = ============================================================ The world of programming with dozenal is steadily becoming more powerful! Member Donald Goodman (#398) published as free software (specifically, GNU GPL v3) back in 11E6, as part of the dozenal suite: http://dozenal.sourceforge.net/ Now there is also a library for using dozenal in Haskell: https://github.com/siddhanathan/dozenal This gives dozenal programmers yet another option; thanks to its author, Siddhanathan Shanmugam of Philadelphia. Though it attracted no votes, there is an interesting debate on the feasibility of introducing dozenals to society: http://www.debate.org/debates/Dozenal-Can-Be-Phased-Into-Society/1/ An interesting presentation on the relative merits of dozenal as opposed to decimal is available: http://www.prezi.com/lpblbyeun9x0/dozenal-system-vs-decimal-system/ Some browsing alerted your editor to the existence of an online encyclopedia of mathematical proofs: https://proofwiki.org/ We've previously delivered encomiums on the virtues of the Online Encyclopedia of Integer Sequences, and we are delighted to have this site to add to our repertoire of mathematical resources. Finally, we mentioned in a previous issue the amazing result of the sum of all positive integers: -0;1. A compelling video proof of this theorem is available: http://www.youtube.com/watch?v=w-I6XTVZXww ============================================================ = SOCIETY BUSINESS = ============================================================ -----------------------Annual Meeting----------------------- To remind our membership: We will be making our presentation at the regional conference of the National Conference of Teachers of Mathematics in Richmond, Virginia on Thursday, 11; (13.) November, from 1:30 p.m. to 2:45 p.m. in the Capital Ballroom of the Richmond Downtown Marriott. Our annual meeting will be at the same location, the Richmond Downtown Marriott, on Friday, 12; (14.) November, (roughly) from 9:00 a.m. to 5:00 p.m. Attendees will be responsible for reserving their own lodging. It promises to be an interesting meeting; to top it off, Gene Zirkel (#67) will be giving a presentation on the founders and other early heroes of the dozenal movement. We hope you will be able to join us! ============================================================ = POETICAL DIVERSION = ============================================================ Dozenal, dozenal, Every number bows to thee; Perfection, abundance, meet with sublimity! Best of all bases, you beat them all, beat them, one to 'leven! Dozenal, dozenal, you're numerical heaven! (With thanks to Rogers and Hammerstein.) ============================================================ = BACKMATTER = ============================================================ _The DSA Newscast_ is a production of the Dozenal Society of America.
