From the Introduction. The slide rule may be defined as an instrument for mechanically effecting calculations by logarithms. Those familiar with logarithms and their use will recognize that the slide rule provides what is in effect a concisely arranged table of logarithms, together with a simple and convenient means for adding and subtracting any selected values. Those, however, who have no acquaintance with logarithms will find that only an elementary knowledge of the subject is necessary to enable them to make full use of the slide rule. It is true that for simple slide-rule operations, as multiplication and division, a knowledge of logarithms is unnecessary; indeed, many who have no conscious understanding of logarithms make good use of the instrument....

A complete road map to creating successful technicalpresentations Planning a technical presentation can be tricky. Does theaudience know your subject area? Will you need to translateconcepts into terms they understand? What sort of visuals shouldyou use? Will this set of bullets truly convey the information?What will your slides communicate to future users? Questions likethese and countless others can overwhelm even the most savvytechnical professionals. This full-color, highly visual work addresses the unique needsof technical communicators looking to break free of the bulletedslide paradigm. For those seeking to improve their presentations,the authors provide guidance on how to plan, organize, develop, andarchive technical presentations. Drawing upon the latest researchin cognitive science as well as years of experience teachingseasoned technical professionals, the authors cover a myriad ofissues involved in the design of presentations, clearly explaininghow to create slide decks that communicate critical technicalinformation. Key features include: Innovative methods for archiving and documenting work throughslides in the technical workplace Guidance on how to tailor presentations to diverse audiences,technical and nontechnical alike A plethora of color slides and visual examples illustratingvarious strategies and best practices Links to additional resources as well as slide examples toinspire on-the-job changes in presentation practices Slide Rules is a first-rate guide for practicingengineers, scientists, and technical specialists as well as anyonewishing to develop useful, engaging, and informative technicalpresentations in order to become an expert communicator.

Calculation and Computation in the Pre-electronic Era

Although it is popularly assumed that the history of computing before the second half of the 20th century was unimportant, in fact the Industrial Revolution was made possible and even sustained by a parallel revolution in computing technology. An examination and historiographical assessment of key developments helps to show how the era of modern electronic computing proceeded from a continual computing revolution that had arisen during the mechanical and the electrical ages. This unique volume introduces the history of computing during the “first” (steam) and “second” (electricity) segments of the Industrial Revolution, revealing how this history was pivotal to the emergence of electronic computing and what many historians see as signifying a shift to a post-industrial society. It delves into critical developments before the electronic era, focusing on those of the mechanical era (from the emergence of the steam engine to that of the electric power network) and the electrical era (from the emergence of the electric power network to that of electronic computing). In so doing, it provides due attention to the demarcations between—and associated classifications of—artifacts for calculation during these respective eras. In turn, it emphasizes the history of comparisons between these artifacts. Topics and Features: motivates exposition through a firm historiographical argument of important developments explores the history of the slide rule and its use in the context of electrification examines the roles of analyzers, graphs, and a whole range of computing artifacts hitherto placed under the allegedly inferior class of analog computers shows how the analog and the digital are really inseparable, with perceptions thereof depending on either a full or a restricted view of the computing process investigates socially situated comparisons of computing history, including the effects of a political economy of computing (one that takes into account cost and ownership of computing artifacts) assesses concealment of analog-machine labor through encasement (“black-boxing”) Historians of computing, as well as those of technology and science (especially, energy), will find this well-argued and presented history of calculation and computation in the mechanical and electrical eras an indispensable resource. The work is a natural textbook companion for history of computing courses, and will also appeal to the broader readership of curious computer scientists and engineers, as well as those who generally just have a yearn to learn the contextual background to the current digital age. "In this fascinating, original work, Tympas indispensably intertwines the histories of analog and digital computing, showing them to be inseparable from the evolution of social and economic conditions.

Rule collectors rejoice! In A Source Book for Rule Collectors with Rule Concordance and Value Guide, Philip Stanley has crafted a masterfully comprehensive illustrated reference guide to the history, uses, and values of measuring instruments. ASource Book for Rule Collectors includes reprints of the best articles from the past 100 years dealing with rules and measurement; extensive coverage of the materials, construction, graduations and uses of rules; a detailed table of the European measures used before the metric system, for identifying rules by size and county of origin; a thorough cataloging of rule accessories; and a complete bibliography of reprints, articles, books, and publications dealing with measuring instruments. The included Rule Concordance and Value Guide gives complete information for identifying and comparing all rules by all major American makers; estimates for each rule’s value based on condition and maker; extensive information on rule value, including condition, selling environment, and charisma. This book is an essential reference. Rule enthusiasts will find the combination a pleasure to read. Mr. Stanley’s breadth of knowledge and his regard for the rules he discusses are apparent throughout. For the antique tool dealer, rule collector, and student of the history of technology, this book is essential.

Carried out over a period of ten years, this is a listing of scientific instruments dating before 1920, preserved in many collections throughout the island of Ireland. It gives location, date, and description for each of the more than 5,000 entries, together, where appropriate, with relevant accompanying detail. It demonstrates clearly that Ireland has an important resource which hitherto had not been appreciated. It also preserves information about collections which have since been lost, sold, or otherwise dispersed.
