I first heard of nomograms on Project Rho's page about calculating spaceship missions: http://www.projectrho.com/public_html/rocket/torchships.php#id--Brachistochrone_Equations--Delta-V--Nomograms http://www.projectrho.com/public_html/rocket/torchships.php#... In addition to being practical calculators, they're amazing higher-order visualization tools. http://www.projectrho.com/nomogram/ http://www.projectrho.com/nomogram/ has more info on how to create them in the context of tabletop wargames.

This is my favorite nomograph: https://www.researchgate.net/profile/Hasan-Al-Mosawe/publication/310626736/figure/fig2/AS:431241901154306@1479827489877/Van-der-Poel-Nomograph.png https://www.researchgate.net/profile/Hasan-Al-Mosawe/publica... It's used for estimating the stiffness of asphalt based on temperature and loading rate. There's a slightly higher resolution version on page 91 of this pdf: https://www.crow.nl/getattachment/Asfalt-Impuls/Projecten/Functioneel-opleveren/2018-11-Asphalt-concrete-stiffness-prediction-based-on-composition-and-binder-properties.pdf.aspx?lang=nl-NL https://www.crow.nl/getattachment/Asfalt-Impuls/Projecten/Fu...

This is a nice article. I know of a couple other resources. First and foremost is the site modernnomographs [1]. Popular mechanics once included a perpetual calendar nomograph [2]. Possibly pynomo [3], a python tool to make nomographs, would also be interesting to others.

Even Mr. Spock uses a nomographic computer when computing course correction angles for the galactic wind. https://www.nicolamarras.it/calcolatoria/regoli_aeronautici_en.html https://www.nicolamarras.it/calcolatoria/regoli_aeronautici_... The takeoff and landing distance charts for many light aircraft are nomographs. https://math.stackexchange.com/questions/2537922/translate-piper-aircraft-performance-graphs-to-mathematical-functions https://math.stackexchange.com/questions/2537922/translate-p...

I made a nomogram of the electromagnetic spectrum many years ago using pynomo while I was still a researcher, that really helped with all of the different units. ps. time flies [1] http://thefreakazoid.blogspot.com/2010/03/nomograms.html http://thefreakazoid.blogspot.com/2010/03/nomograms.html [2} http://pynomo.org http://pynomo.org

Nice. Basically the same as a slide rule. There is a german company that still sells these. [0] [0]: https://www.rechenschieber-werbemittel.de/ https://www.rechenschieber-werbemittel.de/
