alt Hacker NewsWhat Is a Nomogram and Why Would It Interest Me?
Comments
Seriously, 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...
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.
If you like things like this I can recommend you check out the Chris Staecker youtube channel. He covers all sorts of tools people used to use to do math before computers and calculators, and there are a lot of them. Some of the things people came up with to do what today would be considered relatively simple math are pretty clever, pretty complex, or both.

I read the title as "Nonogram" (Picross) at first !
There's an old paper about the mathematics of nomograms that I found interested when I stumbled across it: https://doi.org/10.1016/0001-8708(65)90042-3
I think the Numogram is more interesting, highly relevant today due to AI happenings
The US Navy still uses nomograms for chemistry control on nuclear reactors!
