Know How To Use a Slide Rule?

high_rolla writes "How many of you have actually used a slide rule? The slide rule was a simple yet powerful and important tool for engineers and scientists before the days of calculators (let alone PCs). In fact, several people I know still prefer to use them. In the interest of preserving this icon we have created a virtual slide rule for you to play with." Wikipedia lists seven other online simulations.

I learned how to use my slide rule...

[moosejaw99]

at around 10 years old. I've been using it ever since, and don't plan on ever stopping.

At least

At least a slide rule is more accurate than excel 2007.

Nuclear slide rule.

I prefer to use a tactical nuclear slide rule [colitz.com], myself.

Pheh, youngsters.

[Blnky]

The only slide rule around here is to not push the kid in front of you.

I've never had one required (courses tended to require graphing calculators by the time I got to them), but I found one in my grandpa's desk and learned to use it. Then I carried it with me to high school and gave it to anyone who asked to borrow my calculator.

I grew up after hand-held calculators were ubiquitous, and after slide rules were rare. However, it was also before calculators were allowed on exams, but slide rules were! So, I learned how to use a slide rule. Later on, I was allowed to use a slide rule with all my useful chemistry and physics equations written on it, even though programmable calculators were forbidden b/c they might have formulas stored in them.

the bigger the slide rule, the more accurate the calculation...

Slide Rule vs Excel? would that be a Slip Stick vs Slap Schtick?

So says the poster with an anime name.

Do you hear that sound?

[benhocking]

The hilarity is that if civilization does go in the shitter, it's the so-called "hillbillies" who are going to absolutely own everyone's ass.

For some reason, I'm hearing banjo music...

I did not need that visual.

[Dogtanian]

Well in answer to the question, no. I don't know what a slide rule is for.... but I know that one and one is two.

And if this one could be with you, what a wonderful world this would be.

Re:At least

[slide-rule]

I may be biased here, but I completely concur.

I HATE THE SLIDE RULE.

[Anonymous Coward]

I could NEVER remember how to use it!

So much more complicated than a fucking calculator.

But my Trig teacher INSISTED on slide rules becaUse of something about factors LOL.

I was like that is so old.

So I like failed Trig completely.

ALL SLIDE RULES ARE GOING TO HELL!

I'd rather have my TI-30 anyday!

How do people learn to use them so easily, anyway?

Actually, one AND one is ONE.

A slide rule gets you 3-4 digits faster than a calculator. You have to know how to use it.

I was in the last class in my high school that learned how to use a slide rule. I was in the first class in my college where owning a scientific calculator was required for entry.

As a freshman my Econ professor asked the class if anyone with a calculator would do a division for him. I was carrying an inexpensive plastic slide rule in my back pack. I did the division and said the answer. As he turned to thank me he did a double take and said "What is this?" taking the slide rule from me and holding it up. I said "Its new, a solar powered calculator that never needs batteries." "What will they think of next?" he pretended to marvel.

The point of that whole story is that about 15 people probably had pulled out a calculator and started to do the division and I was able to beat all of them by several seconds.

I did the same thing with my HP-48 because my slide rules were too precious to risk in the hands of others.

Student: "May I borrow your calculator?"
Me: "Sure. Here."
Student searches in vain for any operational familiarity.
Student: "Ummm, no thanks."
