Nomogram (en.wikipedia.org)

I'm a fan of the Project Rho page on Nomograms which has detailed examples of nomograms for spaceflight: http://www.projectrho.com/nomogram/index.html

The site also had a bunch of interesting information on analog computing in the context of spaceflight:http://www.projectrho.com/public_html/rocket/astrodeck.php

This is awesome. Now I'm adding to my TODO list to figure out what kind of calculations I tend to do often (things like intrest rates), and design&print nomograms for them.

I use one for homebrewing: http://www.northernbrewer.com/shop/books-media/software/beer...

It's a great technique. Faster than a calculator or computer program, and satisfyingly physical too.

I recommend looking at the Pynomo package, which also has some great examples: http://pynomo.org/wiki/index.php?title=Main_Page

Nomograms were one of my favorite topics during undergrad (engg)!
