For example, a 10 cm (3.9 in) circular would have a maximum precision approximately equal to a 31.4 cm (12.4 in) ordinary slide rule. Circular slide rules also eliminate "off-scale" calculations, because the scales were designed to "wrap around"; they never have to be reoriented when results are near 1.0—the rule is always on scale.
A slide rule scale is a line with graduated markings inscribed along the length of a slide rule used for mathematical calculations. The earliest such device had a single logarithmic scale for performing multiplication and division, but soon an improved technique was developed which involved two such scales sliding alongside each other.
The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long.
The other side is a circular slide rule. Extra marks and windows facilitate calculations specifically needed in aviation. Electronic versions are also produced, resembling calculators, rather than manual slide rules. Aviation remains one of the few places that the slide rule is still in widespread use. Manual E6-Bs/CRP-1s remain popular with ...
The International Slide Rule Museum (ISRM) is an American museum dedicated to the preservation and display of slide rules and other mathematical artefacts. Established in 2003 by Michael Konshak, who serves as its curator, [3] [4] the museum houses a collection of slide rules from divers manufacturers and time periods, showcasing the evolution and importance of these instruments in the history ...
Rolling slides to break up double plays will not be permitted starting with the 2016 season according to new regulations adopted on Thursday by baseball.
The slide rule was constructed as two coaxial tubes with spiral scales, like the Fuller's cylindrical slide rules, with yet another tube on the outside carrying the cursors. [1] During the Second World War, a closely related version was produced in Germany by Dennert & Pape as the HR1, MHR1 and HR2. [1]
Heat would mostly expand a slide rule rather uniformly, and bending it to a non-circular shape (a straight line is a circle of infinite radius, in some ways) means it does not slide well. Typing the problem in as the parenthesized formula removes the intermediate results from the display; you're given the final answer, and are not even shown ...
