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?

What's a slide rule? smile.gif Just kidding, but in all seriousness while I have seen photos of them I have never actually held one used for engineering/navigation in my hands (I had to add that qualifier because my father collects and uses antique carpenters' tools and has a couple that were once used for figuring scales and angles and such), much less learn how to use it. I did, of course, do lots of timed tests of arithmetic in my childhood; but several years ago I was teaching fifth grade science at a reasonably good school and was astonished and disgusted to discover that none of the kids could multiply or divide by ten without a calculator. (For you non-Americans, fifth grade students here are 10 or 11 years old.) Sigh.
