Slide Rule

AcuMath Slide Rule 400B, Made in the USA c. 1965

There is a Slide Rule Museum website. Will wonders never cease?

I’m not sure how this beauty entered my life. Not that I know how to use it. Perhaps it was my dad’s.

I learned that the Slide Rule is a mechanical analog computer. This one is ‘Simplex Trig.‘ which I am assuming means it can do trigonometry calculations, which I did learn, but used a Texas Instrument Scientific Calculator (which I might still have, surprise surprise). “The era of the slide rule ended with the launch of pocket-sized scientific calculators, of which the 1972 Hewlett-Packard HP-35 was the first.” [Wikipedia]
