1. Slide rulenoun

   a thin, flat calculating device consisting of a fixed outer piece and a movable middle piece. Both pieces are graduated in such a way (as, by a logarithmic scale) that multiplication, division, and other mathematical functions of an input variable may be rapidly determined by movement of the middle pieces to a location on one scale corresponding to the input value, and reading off the result on another scale. A movable window with a hairline assists in alignment of the scales. This device has been largely superseded by the electronic calculator, which has a greater precision than the slide rule. Also called colloquially slipstick.

1. Slide rule

   The slide rule is a mechanical analog computer which is used primarily for multiplication and division, and for functions such as exponents, roots, logarithms, and trigonometry. It is not typically designed for addition or subtraction, which is usually performed using other methods. Maximum accuracy for standard linear slide rules is about three decimal significant digits, while scientific notation is used to keep track of the order of magnitude of results. Slide rules exist in a diverse range of styles and generally appear in a linear, circular or cylindrical form, with slide rule scales inscribed with standardized graduated markings. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in specialized calculations particular to those fields. The slide rule is closely related to nomograms used for application-specific computations. Though similar in name and appearance to a standard ruler, the slide rule is not meant to be used for measuring length or drawing straight lines. At its simplest, each number to be multiplied is represented by a length on a pair of parallel rulers that can slide past each other. As the rulers each have a logarithmic scale, it is possible to align them to read the sum of the numbers' logarithms, and hence calculate the product of the two numbers. The English mathematician and clergyman Reverend William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the electronic calculator, it was the most commonly used calculation tool in science and engineering. 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 electronic computers were being gradually introduced. The introduction of the handheld electronic scientific calculator around 1974 made slide rules largely obsolete, and most suppliers left the business.

1. slide rule

   A slide rule is a manual mechanical analog computer, primarily used for multiplication, division, roots, logarithms, trigonometry and other mathematical functions. It is a simple device that consists of a fixed central part and a movable component with calibrated lines which slide up and down to perform various calculations. They were widely used before the advent of digital calculators and computers.

1. Slide rule

   The slide rule, also known colloquially in the United States as a slipstick, is a mechanical analog computer. The slide rule is used primarily for multiplication and division, and also for functions such as roots, logarithms and trigonometry, but is not normally used for addition or subtraction. Slide rules come in a diverse range of styles and generally appear in a linear or circular form with a standardized set of markings essential to performing mathematical computations. Slide rules manufactured for specialized fields such as aviation or finance typically feature additional scales that aid in calculations common to that field. William Oughtred and others developed the slide rule in the 17th century based on the emerging work on logarithms by John Napier. Before the advent of the pocket calculator, it was the most commonly used calculation tool in science and engineering. The use of slide rules continued to grow through the 1950s and 1960s even as digital computing devices were being gradually introduced; but around 1974 the electronic scientific calculator made it largely obsolete and most suppliers left the business.

Examples of slide rule in a Sentence

1. Charles F. Kettering:

   When I was research head of General Motors and wanted a problem solved, I'd place a table outside the meeting room with a sign: LEAVE SLIDE RULES HERE! If I didn't do that, I'd find some engineer reaching for his slide rule. Then he'd be on his feet saying, Boss you can't do that.
