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 1960 even with the introduction of mainframe digital electronic computers.
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 ...
Mechanical computers can be either analog, using continuous or smooth mechanisms such as curved plates or slide rules for computations; or discrete, which use mechanisms like pinwheels and gears. [clarify]
The company's showroom and office building at 127 Fulton Street in the Financial District of Manhattan K&E manufacturing complex in Hoboken, New Jersey. The Keuffel and Esser Co., also known as K&E, was an American drafting instrument and supplies company founded in 1867 by German immigrants Wilhelm J. D. Keuffel and Hermann Esser.
The use of these early drawings was to express architectural and engineering concepts for large cultural structures: the temples, monuments, and public infrastructure. Basic forms of technical drawing were used by the Egyptians and Mesopotamians to create highly detailed irrigation systems, pyramids, and other such sophisticated structures.
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.
English: A number of slide rules. The white one is an artillery rule, for calculating how to aim a cannon depending on distance to the target. The yellow one is a general purpose Pickett model, typical of mid-twentieth century slide rules.
" In response, I said: "A real slide-rule is 10 inches long. Computer displays aren't big enough, and don't provide adequate resolution, to display a slide-rule. It is possible to zoom the image, but it is horribly cumbersome to use a slide-rule when only 1/3 or less of the slide-rule is visible. Emulators are worthless.
