Re: slide rule magnifiers Message #8 Posted by Mike (Stgt) on 18 Sept 2013, 3:44 a.m., in response to message #7 by aurelio
If you write with a pencil on a piece of paper the letter 'A' and once more 'A' but twice as big as before, well, in both cases it is the letter 'A', there is not more information in the bigger 'A'. Now, if you calculate the SQRT of 7 on an HP-67 and on a -97, the result is the same, on both calculators. So the advantage of the bigger display is _not_ in the accurancy of the result. D'accord?
And the same holds true for reading a slide rule with or without a magnifier lense, using it the reading may be more comfortable, alas there is no gain in accuracy.
