== Collection == | |||
=== Slide Rules === | |||
My most expansive collection. Slide rules are easy to store, repair, and use regularly. | |||
====== Slide Rule Formatting ====== | |||
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). | |||

=== Mechanical Calculators === | |||
My original obsession. Mechanical calculators take more space and effort, so I have comparatively few. | |||
