Slide Rule Took Us to the Moon - See Index Below

Engineers, myself included, that graduated before about 1975 all used slide rules and bought HP or TI calculators. I have KE rule and SR50 in my desk today.

Yes, by 1975 I had stopped using my slide rule and only used my TI SR50, which is long lost. Thanks for the comment

I had an identical one in 1966-1970s. I was the most skilled student with the sliderule in Santa Rosa Junior College. I felt like a gun slinger with it hanging on my belt, and my calculus textbook under my arm.

I remember being the only one in class to get the correct answer in a pop quiz solving a problem that required using the log scales, which I have no idea how to use today.

In 1969 I took an electronics course in highschool and we were required to buy a sliderule.

[@eahawaii1902]

Yes, nobody knew the Slide Rule only a had a few years left after 300 years of life.

[@ianship5058]

I used a slide rule all the time when I first started work

Thanks for your comment. Just recently found my old slides and made the video.

How many calculations can the slide rule do per second?

[@eahawaii1902]

There are other KZbin videos that demonstrate this question. However, I could argue the answer is infinite calculations per second. In my example 2 x 4, once the slide rule calculation is set up every number between 1 to infinity is multiplied by 2. 2 x4, 2 x 3, 2 x 49.59999999 or 2 x (1 to infinity) Thanks for the comment

@ My comment was sarcastic to make a point. Slide rule arithmetic is basic and slow. The slide rule did not send us to the moon.

No dummy, it gets you to proof-of-concept, then you grind out the precision required.
