Report from the Dutch Circle - IM2010 Conference Proceedings CD's and N-Cards
After a successful IM2010 conference last month in Leiden, we offer for sale a number of CD-ROM's with the Conference Proceedings, and sets of N-Cards (Numeracy Cards).
The proceeds will benefit the IM2010 financials and following IM's in the Netherlands.
The CD contains in digital format the full Proceedings (208 pages), but also the presentation slides and annexes, such as references, patents, additional pictures and text.
One can navigate its contents by a user-friendly menu screen.
This CD is offered, together with one set of N-cards (2 cards), for 12 euro apiece, excluding shipping costs – as long as stocks last.
The N-cards were the conference gift for IM2010 participants.
This is a basic slide rule on two credit cards, containing additional aide-mémoire data on nomenclature of extreme small and large numbers (mini & MORE).
N-cards are offered for 5 euro per two sets (2 x 2 cards), excluding shipping costs – as long as stocks last.
For more information about Proceedings (contents, sample paper) and N-cards (detailed pictures, description) visit the Dutch KRING website:
www.rekenlinialen.org
Also you can find in there ordering information, such as payment methods and shipping costs.
On behalf of the IM2010 Committee,

Rechenschieber Sammler Treff (RST)

Report of the RST 19
The 19th RST-meeting took place in the old Roman town of TRIER on April 17th. Beside a swap-market (public was invited and several showed up) we had an ambitous program of very interesting lectures. Werner Rudowski presented a very early brass slide rule from the 19th century made by Dennert&Pape. A special slide rule system Baur from Faber Castell 343 was demonstrated by Peter Holland as some mathematical exotic. Timo Leipälä from Finland acquainted us with some very rare circular slide rules from Russia. After some remarks on recent publications by the organizer Jochen Konrad-Klein we had a fine lunch and the program continued with some instructions to use slide rules for electrical engineers by Klaus Kraemer.
Another highlight for the 35 participants was a video show. Karl Kleine showed us some Hollywood films where slide rules were part of some scenes - and concluded that not all of the actors seemed to be familiar with handling a slide rule.
Some of the lectures are avaliable on our homepage: RST.
The next RST 20 will be organised by Werner Rudowski and will take place in the BOCHUM mining museum, October 23rd. The program is under construction right now and I am sure that it will be an enlightening one again. "
