Here are two nearly identical images. One of these was used by Sergei Korolyev, the other by Wherner von Braun. Can you tell which is which?
And here's a more interesting question -- how many of us here on UMSF have actually *used* a slide rule in their lives? I know I used a slide rule, even in a completely non-engineering field -- I'd use it to do basic scaling functions when doing layout on newspapers and such. Since both Neil Armstrong and Buzz Aldrin took their own personal slide rules to the Moon, people were obviously using them only 35 or so years ago. So, how many of us have ever used one? -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain

Well, I recall using a slide rule a few times.
In High School, probably my Junior year, I purchased a Commodore SR-1400 (IIRC). It broke and it was repaired (!) under warranty. I took the back off and they had replaced a couple of chips in it. Can you imagine trying to repair a calculator these days? I also recall using a key punch around 1975. Those computer cards seem as primitive as counting with sticks now days. I have a 25 year old (~) HP-41CX that still works and sees use. I do not have anywhere near the skills with it as I used to. |
