This discussion reminds me of a watch I saw in a store some years ago. It was a Seiko designed for health workers -- techs, nurses, and doctors. It had two...

Hi Watson, Do you have a list of the rules you are prepared to sell? I hope that you're not selling all of them; surely you are taking a few treasures with you...
Hello Watson. To a 91 y.o.you are still a youngster ! I live in tasmania and am interested in SR's for acoustics, noise and vibration. Have you any ? Regards ...

Hello Watson, I'm sorry to hear that you must sell your collection of 25 years. I'd be really distraught if I have to give up my collection. Is it possible...
Hi All, I enjoy trying to solve the slide rule problems all you smart guys and girls invent. There hasn't been a problem posted in a while. Are you all...
To SR accuracy, find the coordinates of the foot of the altitude of triangle ABC passing through point A where : A = ( 2.6 , 3.4 ) B = ( 5.3 , 7.2 ) C = ( 3.4...
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....

... Since I opened my big mouth, I'll take a stab at this problem. I had to draw the triangle, approximating the location of the coordinates so I could...
Hi Amin, The altitude through A has to be the perpendicular to line BC , not perpendicular to line AC . An altitude of a triangle from a vertex is the...
How far apart ( in miles ) can two buildings that are each 100 feet tall be, such that a camera mounted at the top of one can just barely see the other...
OK Folks. Trying again after relearning my definitions for a triangle. Spoiler space starts here... Spoiler space ends here... x = 2.2 and y = 3.8 with the...
Great work, Amin ! I just posted a more physics oriented problem, distance between bldgs. Gary Flom ... From: Amin Aur To: sliderule@yahoogroups.com Sent:...
... Gary, you do realize that in a way you worded the problem it does not have a solution, do you? You see, buildings are built on dry surface and dry surface...
OK, Gary, now let's see the solution in complex numbers. I am working on it but it has been too many years and I have to do a lot of refreshing. Marion Moon...
Hello Andrew, As might be expected in a problem such as this, ideal settings are assumed. Certainly need to assume there are no visual obstructions, no bending...
Hello everybody the distance between the bases of the two buildings is twice the distance from the base of the building to the horizon (where the tiniest...

Gary, I suspect you've got a more sophisticated method in mind (and which I'd have to think about) rather than the rule usually used by navigators (below),...
Hi John, Excellent ! And thanks for the great explanation . Gary Flom ... From: JohnStClaire@... To: sliderule@yahoogroups.com Sent: Tuesday, November 07,...

Hi Ray, John, and others, That one part where you have to find theta for cos theta = .999995 needs to be done with something that gives more digits than a SR ....

Hi John, Would need some ~very accurate~ ( and credible, which would be hard to be certain of )measurements, as we are talking relatively short distances....
