research on slide rules and related instruments
last edit: 20230103
 In 2022 I attended two inperson conferences of historians
of mathematics in Germany and Austria, the first life
meetings after the two year break due to the COVID pandemic,
where I also gave talks:
 Slide rules in westgerman schools after WW2,
in particular ARISTO school slide rules
Joint conference of the
history of mathematics
special interest group
of the
DMV,
the German Association of Mathematicians,
and the
corresponding group
of the
GDM,
the Association for the Didactics of Mathematics,
Hildesheim, May 2528, 2022.
My presentation was in German, no proceedings.
More below, see IM2022.
 Robert Nelting, his life and his slide rules
XV. Austrian Symposium on the History of Mathematics,
Miesenbach, June 1218, 2022.

publications
This article will later be augmented by more technical
details previously researched by me and
Günter Kugel, probably in the
Journal of the Oughtred Society
(JOS).
 I still have to finish the proceedings of IM2021 after these
two conferences.
This is planned for the near future.
 I gave two presentations as IM2022, the
International Meeting of Collectors and Researchers
of Slide Rules and other Mathematical Instruments,
held online, September 1718, 2022.
 Aristo School Slide Rules

in Hildesheim
 The Wind Rises — an animation film
featuring slide rules
Instead of a proceedings volume the written record of this
conference will be published as a set of articles in JOS, the
Journal of the Oughtred Society
.
 March 1519, 2023: Naunhof near Leipzig:
Followup of the Hildesheim joint conference mentioned above,
where I plan give a talk on
about all kinds of preprinted paper for drawing graphs in
various types of coordiante systems, like squares papers,
logarithmic papers, probability papers,
papers using polar coordinates, etc, etc,
and their history.
you see, I have a lot to do in my retirement ...
