From the smug vantage point of the early 21st Century, it's easy to forget that not that long ago the threat of nuclear destruction was a part of everyday life. These radiation monitoring chats were mostly developed in the 1950s and 1960s and are beautiful examples of how to render complex calculations in a meaningful and readable way.

Slides rules are actually astonishingly powerful things. The simple slide rule does multiplication and division using the C and D scales; strictly speaking, you can have a basic rule with nothing but C and D. But you almost never see a rule that simple. (The only one I've ever seen with only the two scales was a circular rule used as a promotional giveaway.) The other scales are where things get a bit complicated; but it's a lot of fun to figure out how they work, and to see how much you can actually do with, basically, two attached rulers with a bunch of different markings.
