The Smith chart is the electrical engineer's favorite: https://en.wikipedia.org/wiki/Smith_chart You either love it or hate it, depending on how well your electromagnetics class was taught.

What Is a Nomogram and Why Would It Interest Me?

#22Here’s an old python program to make pdf nomograms from almost any formula. The example of payment for a loan is one of my favorites. https://github.com/lefakkomies/pynomo
That is TFA.

#23So far my children have not yet had to repeatedly perform complicated calculations, but I look forward to the day. I will definitely teach them with nomograms before we go on to spreadsheets!
Another type of almost-nomogram that's great and practical is the slide rule. In particular in the kitchen, where it makes it really easy to translate proportions. https://entropicthoughts.com/kitchen-slide-rule

#25Seriously, though, there's one nomogram you (yes you) should know about and have it well-enough engraved in your mind's eye that you can use it with eyes closed. A nomogram for Bayes' theorem: https://www.ovid.com/journals/nejm/abstract/10.1056/nejm1975...
Can you use actually use it eyes closed? Never heard of that level of precision in the mind's eye
You're right that I can't reproduce it like a phone camera could, and that the more precise you are the better (and it might be that with my eyes closed I'm doing something closer to addition in log-odds, like a separate comment responded), but this is super useful even coarsely. The visual affordance gives Bayes's theorem a physicality unlike any other tool I've found.

Somehow I looked at the article and completely missed that it was the introduction to Pynomo. My wife would back you up that I am not good at finding things...
