Overview of fancier slide rules (folded scales, extended scales, LL scales)

Want to "level-up" your slide-rule ability? This video is a short introduction to the more advanced scales found on scientific slide rules. I think it's one of my best videos. It gives an overview of folded scales (e.g. CF/DF), extended scales (e.g. ST/T2), and log-log scales (LL). This v

Pythagorean (P) Scale on slide rules

This video explains the theory and use of the Pythagorean "P" scale on some slide rules. While rare on American rules, it was fairly common on slide rules from elsewhere (especially on "Darmstadt" style and other sophisticated rules). Slide Rule Playlist (starts with basic videos): Playli

Basic slide rule theory and use (Part 1): C and D scales

The first of a series of videos explaining the basic slide rule. I'm not an expert -- I'm also not old enough to have learned slide rule use in school. This series of videos aims to be the set of videos I would have enjoyed while learning about the slide rule -- it assumes some mathematica

Log-Log (LL/LL0) scales in detail

This video explains the Log-Log (LL) scales on the slide rule in more detail than my earlier video ("Overview of fancier slide rules"). These scales are for computing arbitrary powers and logarithms. I finish by solving an exponential decay problem. Mannheim and Rietz type rules usually d

W Scales -- Faber Castell 2/83 Style

I describe the usage of the double length W scales which give a 5" slide rule the precision of a 10" and a 10" slide rule the precision of a 20". My apologies for the wacky brightness -- after YouTube killed the video editor, it's a bit harder to work with the raw video.

Two operations with one slide using folded scales

This video gives a technique for computing any sequence of two multiplications/divisions, in any order, on a slide rule with a full set of folded scales (you need C/D/CI/CF/DF/CIF). This increases the accuracy of the result versus using the naive method of one setting per operation. I'm n

Trigonometry on Euro-style (Darmstadt, studio, 2/83, etc.) slide rules

This video discusses trigonometry again, this time using a slide rule with trigonometric functions on the base instead of the slide. I discuss direct reading the trig. functions, multiplying and dividing them, and the solution of various triangles. At the end is a very efficient procedure

Circular Slide Rules: Faber Castell 8/10 + Sama & Etani Model 90

I take a look at a couple circular slide rules and discuss some pros and cons. There are a few errors: - The Gilson "binary" slide rules are thus named for having a scale of binary fractions (denominators that are powers of 2), not for have the double, caliper-style cursor. - The A and B

I show how to compute length or distance on the slide rule in 2 and 3 dimensions using the trigonometric scales S and T. Specifically, I show how to efficiently calculate: sqrt(a^2+b^2) AND sqrt(a^2+b^2+c^2) The latter calculation I have never seen in a manual or online, although I'm sur
