Before the advent of the scientific pocket calculator, it was the most commonly used calculation tool in science and engineering. [3] The slide rule's ease of use, ready availability, and low cost caused its use to continue to grow through the 1950s and 1960s, even as desktop electronic computers were gradually introduced.
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.
Engineering statistics dates back to 1000 B.C. when the Abacus was developed as means to calculate numerical data. In the 1600s, the development of information processing to systematically analyze and process data began. In 1654, the Slide Rule technique was developed by Robert Bissaker for advanced data calculations.
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 ...
The Coggeshall rule consisted of two rulers, each a foot (30 cm) long, which were put together in various ways. The most common and convenient arrangement was to have one of the rulers slide within a groove made along the middle of the other, like an ordinary linear slide rule, as shown in the figure below.
A Smith chart to calculate electrical impedance with no values plotted; although not a nomogram, it is based on similar principles. Like a slide rule, a nomogram is a graphical analog computation device. Also like a slide rule, its accuracy is limited by the precision with which physical markings can be drawn, reproduced, viewed, and aligned.
A scale ruler is a tool for measuring lengths and transferring measurements at a fixed ratio of length; two common examples are an architect's scale and engineer's scale. In scientific and engineering terminology, a device to measure linear distance and create proportional linear measurements is called a scale.
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 E6Bs/CRP-1s remain popular with ...
