Engineer using a slide rule, with mechanical calculator in background, mid 20th century. A more modern form of slide rule was created in 1859 by French artillery lieutenant Amédée Mannheim, who was fortunate both in having his rule made by a firm of national reputation, and its adoption by the French Artillery. Mannheim's rule had two major ...
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.
A slide rule. The sliding central slip is set to 1.3, the cursor to 2.0 and points to the multiplied result of 2.6. The slide rule was invented around 1620–1630, shortly after the publication of the concept of the logarithm. It is a hand-operated analog computer for doing multiplication and division.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
In 1834, Babbage started to design his analytical engine, which will become the undisputed ancestor of the modern mainframe computer [71] with two separate input streams for data and program (a primitive Harvard architecture), printers for outputting results (three different kind), processing unit (mill), memory (store) and the first-ever set ...
SLIDE-RULE-BRIEF.PDF is a short document that provides a quick introduction to how the program works. SLIDE-RULE.PDF is a much longer book (about 300 pages) that provides more extensive information about the slide-rule software, and also extensive information about some non-computer encryption systems that I have invented.
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 ...
A slide rule is a mechanical analog computer. Slide Rule may also refer to: Slide Rule, a 1992 album by Jerry Douglas; Slide Rule (horse), thoroughbred racehorse; Slide Rule: Autobiography of an Engineer, a partial autobiography of the British novelist Nevil Shute
