Hi John, Go ahead and send it to this address : 235667 ( at ) bellsouth ( dot ) net . My old address needs updating on the website . Thanks. Gary ... From:...
Hi Jim, The following articles by Peter Hopp, Colin Barnes and John Knott may be of use in determining the age of your PIC rule: Author: Peter M. Hopp Title:...
Thanks for the info! A lot of intersting stuff there. I still can't nail down the date exactly, but i think I can safely say it is "old" Thanks again everyone....
Hello Walter. Since you posted your request I have done a bit of research into various miniature screw threads, and have checked a number of slide rules in my...
Since you folks were so helpful with my last question I thought that I might asked another. I have been spending a lot of time brushing up on my slide rule...
I have actually done that, but the K-scale goes the wrong direction to make it work for me, unless one does a transfer to the K scale, which may actually be...
A simple solution if you have K on the slide (e.g. Aristo Studio or StudioLog). Start with index to index. 1. Hairline to (a) on K. 2. Slide to (c) on B under...
Hi Charley, Rod, and the gang; Then you can do test solving the whole thing in two "cycles" of set cursor then pull slide while using just the a/b/c/and d/...
A friend is looking for what he describes as a 15 inch, Faber-Castell artillery rule, in excellent to new condition. If anyone has one that they wish to sell,...
I rewrote the equation as such: cube root( a*b/(c*squareroot(c))) so that the a*b/(c*sqrt(c)) can be done easily via C/D and B, but I then have to an xfer to...
I'm wondering why manufacturers have bothered to put ST (or SRT) scales on slide rules. For angles less than 0.1 radians (about 5.73 degrees) it is assumed...
Hi Vaughn, Having the SRT scale just saves a step if the sine or tangent is part of a chained calculation. For the same reason, you want the trig scales...
The Germans invented the P scale to deal with the cosine of small angles. You are right, the ST is not needed as a general rule and early slide rules, both...
Another thing I want to add is that not all manufacturers used radians on the SRT scale - some used sin and some apparently used the mid-point between sin and...
Greetings, There are a lot of things we do on this list which may not be obvious to newcomers, and some of us veterans need reminders from time to time, too....

I'll be adding a long row of input/output boxes below my virtual slide rule with the normal things like trig, log, and exponents. I would appreciate any...
I have a virtual rule with digital readouts at http://www.stefanv.com/calculators/aristo970/index.html . I used Derek's code (with permission) and added the...
Hi Lads I am impressed by the working on-screen slide rules. I am wondering if it would be possible for the 'nudge' keys to be brought into play somehow to ...
Hi Ray, Those are some great ideas! One of the advantages to a virtual rule should be the ability to provide, and make available to the user, better accurracy...
I wasn't aware of your virtual rule - looks very nice! Pretty much exactly what I was intending to do except I plan on the addition of input boxes to set the...
Also, sometimes SRT scale is graduated is degrees and minutes rather then degrees and decimal parts of a degree. This allows to skip steps to convert...
... Well, JavaScript's floating point model isn't any worse than any other. The big problem with virtual slide rules is that it's virtually impossible to make...
Thanks Ray, for the idea. It only took a few minutes to do this. I may make it a little better later. Be sure to read the help, because the nudge is relative...
Hello Stefan, I'm fascinated by the whole idea of the virtual slide rule, especially those replicating existing rules or offering more scales than usual. For...
Since you asked; YES please keep this going here. I am enjoying it. Very best regards; Bob Finch ... Liviu Librescu - Īn veci pomenirea lui. (May his memory...
So, here was the problem that I was looking for a "smooth" solution to using my DeciLon: x = cuberoot(1.47)*cuberoot(3.25)/squareroot(7.5) I rewrote it to look...
