The ordinary slide-rule, or Gunter's scale, invented many years ago, for approximation or a rough check on ordinary calculation, has been found of great utility. It is, however, unfitted for the more exact calculations of the engineer, architect, and actuary, and does not satisfy all the requirements of scientific investigation or of financial transactions. The value of the slide-rule as a calculator depends upon the accuracy of its results, upon the rapidity with which those results can be found, upon the variety of its useful applications, and upon the small amount of mental and physical effort required in the solution of problems. With any form of slide-rule the results are necessarily approximate, the degree of approximation depending upon the length of scales, the care observed in their manufacture, and the material used. With the ordinary construction and material it is not practicable to make such length of scales as will give results beyond the third place, which latter is frequently in doubt, the doubt being still further increased by the unequal shrinkage of the material of which it is made, usually boxwood. The ordinary rule in use is 12 inches long, with radii of n and 5 DEGREES inches, . the divisions of which are cut by hand, copying from a machinedivided plate. In the present instrument the radii are 60 and 30 feet, the divisions of which are printed directly from machine-divided plates. These plates contain over 33,000 divisions, calculated to seven places of decimals from Babbage, s tables by using a common multiplier, every line being subjected to correction for error of screw and temperature variation, so that possibly every line centre is within .0001 inch of its true place. The plates contain over 17,000 engraved figures. The work was executed by W. F. Stanley, of London, upon a dividing-machine made expressly for this rule, the diamond point used for cutting the divisions being moved by a screw of 50 threads per inch, reading by micrometer to .000001 inch. It was a work requiring much time, care, and skill. The framework of this rule is of metal throughout, therefore not injuriously affected by variations in temperature nor moisture, no time, pains, or expense having been spared to make the instrument in every way reliable; the scales, being of great length, will give results correctly to four, and usually to five, places of figures, sufficient to satisfy nearly every requirement of the professional and business man. A knowledge of its use is readily acquired. The rules following a1e general, simple, and easily remembered. After once becoming familiar with the movements results are obtained with almost incredible rapidity; ordinary calculations, and complicated formulae involving roots and powers, being solved with nearly equal facility....

Available in PDF, EPUB and Kindle. Book excerpt: Wie rechnete man bevor es Computer gab? Mit welchen Rechenhilfsmitteln konnten Ingenieure Maschinen konstruieren, die sicher und effizient funktionierten, Architekten Bauwerke planen, deren Statik sicher war, Wissenschaftler aus Meßreihen die Gesetze der Natur errechnen, und Kaufleute Gewinn und Verlust zahlenmäßg im Griff haben? Mit Rechenschiebern, Rechenmaschinen, Tabellenwerken und mathematischen Spezialinstrumenten erbrachten unsere Vorfahren verblüffende Leistungen. Dies galt ganz besonders in der Zeit der Zweiten Industriellen Revolution zwischen der Mitte des 19. und des 20. Jahrhunderts, als eine ganze Reihe technischer Erfindungen das Leben dramatisch veränderte, wie Strom und Licht, Auto und Flugzeug, Telefon und Radio, und viel und vielseitig gerechnet werden mußte, um all dies zu erschaffen. Zu diesem Thema trafen sich Sammler und Forscher von Rechenschiebern und anderen Rechenhilfsmitteln im Oktober 2013 in Berlin zu einer internationalen Konferenz unter dem Motto "Rechnen für Wissenschaft, Entwicklung und Produktion: Rechengeräte für die zweite industrielle Revolution". How did we compute in the ages before the advent of the modern digital computer? What were the instruments to help engineers, scientists, business men and others to perform arithmetic and other mathematical computations for their work? Using slide rules, adding machines, tables, and special instruments our ancestors achieved stunning results, particularly in the times of the Second Industrial Revolution. In the time frame from 1850 to 1950 a broad wave of inventions and technological developments changed life dramatically: Electricity provided power and illumination, cars and airplanes made us a mobile society, telephones and radio gave us unprecedented communication. All that required computation in one way or other. The International Meeting of collector and researchers of slide rules and other historical computing instruments of 2013 took place in Berlin, the largest European industrial metropolis in this period. This richly illustrated book is a collection of papers from this conference.
