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.
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.
In measurement, the Coggeshall slide rule, also called a carpenter's slide rule, was a slide rule designed by Henry Coggeshall in 1677 to help in measuring the dimensions, surface area, and volume of timber. With his original design and later improvements, Coggeshall's slide rule brought the tool its first practical use outside of mathematical ...
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 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 ...

Schumacher's original design, from which the Model 366 slide rule deviates only slightly Number table depicted on the slide rule. The A. W. Faber Model 366 was an unusual model of slide rule, manufactured in Germany by the A. W. Faber Company around 1909, with scales that followed a system invented by Johannes Schumacher (1858-1930) that used discrete logarithms to calculate products of ...
