Collection[edit | edit source]
Slide Rules[edit | edit source]
My most expansive collection. Slide rules are easy to store, repair, and use regularly.
Slide Rule Formatting[edit | edit source]
When describing layouts of slide rules, the following standard is used:
- scales are ordered from the top to bottom of the rule, separated by spaces
- parentheses "()" denote scales on the slide.
- scales placed back-to-back or on the same line are separated by a forward slash "/."
- scales are named as written on the rule, subscripts may be used to differentiate scales for clarity.
- ascending scales are written in black, descending scales are written in red (with the exception of Versalog cosine scales, to match the form on the rules).
