Yep, sure can. Still have a few from 60's when I did engineering.
Computers are great but they produce sooooo many decimals that mostly are meaningless.
Slide rules gave a better perspective about accuracy of a calculation.
My uncle can use a slide rule to do some super radical calculations. I've heard of other old people actually using them as well. I even saw a wood and glass model, manufactured in 1938, to meet Alan Oppenheimer's precise specifications, go for over 10,000 bucks on Craigslist.
Slide rules no, but I used log tables. Now I just use my calculator.
My mental arithmetic is not that good, but I make it a point to estimate how much my shopping cost when I am at the checkout counter. But I can only do it if there are no more than 25 items. More than that, I know I am in deep shit (cash wise) so I don't bother counting and just take out the plastic.
Actually, I think that my high-school physics class was one of the last at my school to use slide rules. Pocket calculators were just beginning to appear at that time (the mid-1970s), but we were required to use the slide rule. I'm not sure if I would be able to use one now. I haven't seen one in about 35 years.
Used to use one, but probably wouldn't be able to do it today...:frown1:
I still have mine in the green leather case...It was given to me by
my father, and...yes, it's also make of ivory also...
It was originally my father's when he studied engineering at Georgia Tech..
