·I went through four years of engineering curriculum and used a 6" Pickett slide rule the whole time (pre calculator days), but have no desire to fiddle around with slide rules now. I had a Navitimer and they look cool, but I never used its function, instead I have a 35 year old HP 11 scientific calculator on my desk and an app for it on my tablet if I need to do any complicated calculations. Time moves on.

·Even if you know how to use it, it's not that helpful without a loupe. 😲

··Oooo subtitles!Pity they didn’t fit a working gasket instead of a slide rule. Now there was an engineering problem in need of a solution.

A search of the chaos on my desk exposed five slide rules -- and a boomerang.
One Faber-Castell single-sided from my school days.
Two British Thornton "comprehensive", one of which I bought in my first year in college, price £4-4-0
One E6B low speed air navigation computer from Air Products Research Inc
One "Gear Rating Computer for Straight Spurs and Helicals" from Fearns Calculators, Newcastle-U-Tyne.
One boomerang I made myself and yes, it does fly and return -- at high speed 😲
There are more in other disorganised piles of "stuff". Including a Les Leston "Speedmaster" rally computer.
As a bonus I've been meaning to clear up my desk for a long time, so this is a start....

·To think, a simple “3 and 6 minute rule” accomplishes a lot of this using just the chronograph minute totalizer
