Sometimes it is not that immediate to see what is the math relation behind some choices, like inverted scales that can be used for multiplication too. I used a slide rule (Pickett N4-ES) through both my undergraduate and graduate college career. I continued to use it at the beginning of my professional career until "sliderule" calculators came out. I have continued collecting and using slide rules as a hobby. (Second only to HP calculator collecting and using.) I thought you might be interested in the math that is used to create the various slide rule scales. Thus the attachment. Different manufacturers sometimes used different formulas. For example, the folded scales were not always folded at pi. Anyway, enjoy. John |
