Nota de Cesaris sobre los artículos citados.


March 2, 2025

To our Slide Rule Research and Collecting Community,

 

IEEE-Eta Kappa Nu (the Honor Society of the IEEE [Institute of Electrical and Electronic Engineers]) publishes a periodical online news magazine named ‘The Bridge.’  The current issue that focuses on slide rules has just been published and is dedicated to the ‘Advancement of Technology Using Slide Rules.’  Both Mike Syphers and I were invited to contribute articles to this edition, with Mike’s article focusing on the uses of the slide rule and mine on the history of its invention, innovation, and development.

 

The magazine can be downloaded or viewed at  https://hkn.ieee.org/news-and-announcements/the-bridge

Here one has the choice to ‘download the issue’ or ‘read it online.’  Control Click on the link and choose the option ‘Read this Issue Online’ and then use the arrows at the right and left to page through the magazine.

 

Alternatively, one can use the direct link here  https://magazines.ieee.org/hkn/library/page/issue_1_2025/1/ to take you directly to the ‘Read this Issue Online’ option.

 

The two articles complement each other very well and the editors did an excellent job of putting this issue together.  Hopefully these articles will prove entertaining, interesting, and instructive or our community, both to our long-time members and as a nice welcome to our new members.

 

Kind regards,

Mike Syphers

Hola colegas

Robert de Cesaris , el "jefe" de la Oughtred Society ha publicado un artículo sobre la historia de las reglas de cálculo en una revista americana.

Dicha revista contiene otro interesante artículo sobre el mismo tema.

Aun hay gente interesada por este noble instrumento.

Dear Slide Rule Collectors.

During the Virtual International Meeting 2024, we - as KRING - proposed to initiate a WORKSHOP SLIDE RULES in between the International Meetings, in the beginning of the year 2025, with the purpose to meet each other on an international scale and have Slide Rule discussions. The intention is to discuss technical items during this WORKSHOP of about 2 hours. General items can be discussed during the yearly International Meetings.

Most, or all, of us have one or more Slide Rules or Slide Charts which cannot be identified by Brand, Manufacturer, Distributor, or aspects as purpose, strange scales, etc. This WORKSHOP opens the possibility to ask fellow collectors to help you with these questions

As a result of the Pre-announcement, there are already 17 participants and some have even already provided their UNKNOWN slide rules. So there are sufficient items to discuss!!

The 2 hour WORKSHOP is planned on Sunday 23 February 18:00 to 20.00 hour CET, (Amsterdam time), so we start at 17:00 UTC, 13:00 EDT, 10:00 PDT and for Eastern Australia (AEDT) Monday 5:00.

You are welcome to take a photo of your UNKNOWN slide rules, and send it to info@rekeninstrumenten.nl before 20 February. We will collect all these UNKNOWN Slide Rules on a page on our website:  https://www.rekeninstrumenten.nl/workshop  This page already includes some unknowns, so you can look at them before the meeting, to see if you can help to answer the questions.

During the WORKSHOP the owner of the unknown item explains his questions. Your international colleague collectors will help you answering your questions. Some answers could be very simple, just because a fellow collector knows about it

Please let us know before 20 February if you are interested to participate. We will then submit you the Zoom link a few days before the meeting.

To all country organizations: Please distribute this Announcement in short term to your members and others who could have been interested.

Hope to see you on Sunday 23 February for the WORKSHOP SLIDE RULES.

Regards,

Andries de Man, Leo van der Lucht, Karl Kleine, Chris Hakkaart

Sí que es bonita y muy potente.

Sigamos la tradición a pesar de la ausencia de nuestro querido Jorga

  ¡¡¡FELIZ AÑO NUEVO !!! 

Todo lo bueno que querais para todos los camaradas

Abrazos

Hola

Acabemos el año viendo esta regla francesa rara, según Daniel, utilizada para los cálculos de trabajo de las máquinas herramientas.
Se asemeja a la famosa regla de Barth / Taylor que podeis descubrir en este artículo:

Pues nada más  ¡FELIZ AÑO NUEVO 2025!

Hola a todos:

Acabo de ver el chat. Me alegro, MAAG57, que te haya gustado la exposición. Imagino que Carlos Abelleira (cac) también la habrá visitado.

Siento no haberme enterado de vuestra visita al edificio El Sario de la Universidad Pública de Navarra (Upna). Me hubiese gustado acompañaros y hacer de guía en esas visitas. Y ver con detalle las diferentes vitrinas, los paneles explicativos (situados detrás) y los aparatos simulados que se pueden activar en el ordenador de la exposición.

Si alguien más pasa por Pamplona y se anima a visitar la exposición, que no dude en avisarme. Lo puede hacer a través del teléfono de Actividades Culturales de la Upna, 948-168408. O de mi número de móvil 609-406790. Será un placer acompañaros.

Un saludo,

Antonio

Interesante !

No tengo muy claro su uso, el aprovechamiento de la madera de troncos tiene muchos muchos bemoles...  Por aqui (aún hoy) ni siquiera se usan unidades métricas en el mercado maderero...
Habrá que ir a ver el libro citado por Gonzalo...

Por otro lado, a Papá Noel "no le gusta" Barcinar... y los Reyes Magos lo declararon "persona no grata"...

Gratos Saludos.
