Remember, it's just a mechanical way to add and subtract logarithms, so if you put the left index of the slide over "2" on the bottom scale and look down the slide to "3", it will be over "6".

Marvin has a great idea, put your slide rule in a nice wooden case, with a glass front. Keep it with your computer, with a sign, "in case of emergency, break glass"

LOL! I'm an engineer and I collect old slide rules, drafting sets, math and technical books (I have an old K&E catalog from WWI), etc. I haven't added an abacus to the collection yet, though. Maybe soon...

Cool! I have several math and science books from the late 1800s, but no Principia. You are indeed blessed among geeks.
