  • Analytical Engine, 1838 ALLAN G
    Charles Babbage’s Analytical Engine, 1838 ALLAN G. BROMLEY Charles Babbage commenced work on the design of the Analytical Engine in 1834 following the collapse of the project to build the Difference Engine. His ideas evolved rapidly, and by 1838 most of the important concepts used in his later designs were established. This paper introduces the design of the Analytical Engine as it stood in early 1838, concentrating on the overall functional organization of the mill (or central processing portion) and the methods generally used for the basic arithmetic operations of multiplication, division, and signed addition. The paper describes the working of the mechanisms that Babbage devised for storing, transferring, and adding numbers and how they were organized together by the “microprogrammed” control system; the paper also introduces the facilities provided for user- level programming. The intention of the paper is to show that an automatic computing machine could be built using mechanical devices, and that Babbage’s designs provide both an effective set of basic mechanisms and a workable organization of a complete machine. Categories and Subject Descriptors: K.2 [History of Computing]- C. Babbage, hardware, software General Terms: Design Additional Key Words and Phrases: Analytical Engine 1. Introduction 1838.

  • Analytical Engine: the Orig- Inal Computer
    Chapter 2 Analytical Engine: The Orig- inal Computer As we learned in the fourth grade science course, back in 1801, a French man, Joseph Marie Jacquard, invented a power loom that could weave textiles, which had been done for a long time by hand. More interestingly, this machine can weave tex- tiles with patterns such as brocade, damask, and matelasse by controlling the operation with punched wooden cards, held together in a long row by rope. 1 How do these cards work? Each wooden card comes with punched holes, each row of which corresponds to one row of the design. In each position, if the needle needs to go through, there is a hole; other- wise, there is no hole. Multiple rows of holes are punched on each card and all the cards that compose the design of the textile are hooked together in order. 2 What do we get? With the control of such cards, needs go back and forth, moving from left to the right, row by row, and come up with something like the following: Although the punched card concept was based on some even earlier invention by Basile Bou- chon around 1725, “the Jacquard loom was the first machine to use punch cards to con- trol a sequence of operations”. Let’s check out a little demo as how Jacquard’s machine worked. 3 Why do we talk about a loom? With Jacquard loom, if you want to switch to a different pattern, you simply change the punched cards. By the same token, with a modern computer, if you want it to run a different application, you simply load it with a different program, which used to keep on a deck of paper based punched cards.

  • Ada and the First Computer
    Ada and the First Computer The collaboration between Ada, countess of Lovelace, and computer pioneer Charles Babbage resulted in a landmark publication that described how to program the world’s first computer by Eugene Eric Kim and Betty Alexandra Toole eople called Augusta Ada King’s father “mad and bad” for his wild ways, but he was better known as Lord Byron, the poet. Ada inherited her famous father’s P way with words and his zest for life. She was a beautiful, flirtatious woman who hobnobbed with England’s elite and who died at the youthful age of 36, the same age at which her father died. And like Byron, Ada is best known for something she wrote. In 1843 she published an influential set of notes that described Charles Babbage’s An- alytical Engine, the first automatic, general-purpose computing machine ever designed. Although the Analytical Engine was never built—largely because Babbage could not raise the funds for its construction—Ada’s notes included a program for using it to com- pute a series of figures called Bernoulli numbers [see box on page 78]. Ada’s notes established her importance in computer science, but her fascinating life and lineage—and her role as a female pioneer in a field in which women have always been notoriously underrepresented—have lately turned her into an icon. In addition to numerous biographies, she has inspired plays and novels written by the likes of such lu- minaries as Tom Stoppard and Arthur C. Clarke. Conceiving Ada, a movie loosely based on her life, was released by Fox Lorber in February.

  • A Short History of Computing
    A Short History of Computing 01/15/15 1 Jacques de Vaucanson 1709-1782 • Gifted French artist and inventor • Son of a glove-maker, aspired to be a clock- maker • 1727-1743 – Created a series of mechanical automations that simulated life. • Best remembered is the “Digesting Duck”, which had over 400 parts. • Also worked to automate looms, creating the first automated loom in 1745. 01/15/15 2 1805 - Jacquard Loom • First fully automated and programmable loom • Used punch cards to “program” the pattern to be woven into cloth 01/15/15 3 Charles Babbage 1791-1871 • English mathematician, engineer, philosopher and inventor. • Originated the concept of the programmable computer, and designed one. • Could also be a Jerk. 01/15/15 4 1822 – Difference Engine Numerical tables were constructed by hand using large numbers of human “computers” (one who computes). Annoyed by the many human errors this produced, Charles Babbage designed a “difference engine” that could calculate values of polynomial functions. It was never completed, although much work was done and money spent. Book Recommendation: The Difference Engine: Charles Babbage and the Quest to Build the First Computer by Doron Swade 01/15/15 5 1837 – Analytical Engine Charles Babbage first described a general purpose analytical engine in 1837, but worked on the design until his death in 1871. It was never built due to lack of manufacturing precision. As designed, it would have been programmed using punch-cards and would have included features such as sequential control, loops, conditionals and branching. If constructed, it would have been the first “computer” as we think of them today.

  • NVS 3-1-2 P-Jagoda
    Clacking Control Societies: Steampunk, History, and the Difference Engine of Escape Patrick Jagoda (University of Chicago, Illinois, USA) Abstract: Steampunk fiction uses strategic anachronism, counterfactual scenarios, and historical contingency in order to explore the interconnections between nineteenth-century and contemporary techno-scientific culture. William Gibson and Bruce Sterling’s novel The Difference Engine (1990), a prominent exemplar of this contemporary genre, depicts a neo- Victorian setting in which the inventor Charles Babbage builds a proto-computer based on the “Analytical Engine” design that he proposed but never actually constructed in our own nineteenth century. The alternative chronology of the novel re-imagines Victorian texts and historical events, including Benjamin Disraeli’s Sybil (1845) and the industrial revolution, in order to examine literary history and investigate historiography. This essay analyses The Difference Engine ’s commentary on the history of power relations. It contends that the novel’s alternative genealogy helps us examine the evolution of control systems and think about the shape of history. Keywords : biopolitics, control, The Difference Engine , William Gibson, historiography, power, self-reflexivity, steampunk, Bruce Sterling, technology. ***** Verily it was another world then…. Another world, truly: and this present poor distressed world might get some profit by looking wisely into it, instead of foolishly.

  • Introduction to Computing: Explorations in Language, Logic, And
    6 Machines It is unworthy of excellent people to lose hours like slaves in the labor of calculation which could safely be relegated to anyone else if machines were used. Gottfried Wilhelm von Leibniz, 1685 The first five chapters focused on ways to use language to describe procedures. Although finding ways to describe procedures succinctly and precisely would be worthwhile even if we did not have machines to carry out those procedures, the tremendous practical value we gain from being able to describe procedures comes from the ability of computers to carry out those procedures astoundingly quickly, reliably, and inexpensively. As a very rough approximation, a typical laptop gives an individual computing power comparable to having every living human on the planet working for you without ever making a mistake or needing a break. This chapter introduces computing machines. Computers are different from other machines in two key ways: 1. Whereas other machines amplify or extend our physical abilities, comput- ers amplify and extend our mental abilities. 2. Whereas other machines are designed for a few specific tasks, computers can be programmed to perform many tasks. The simple computer model introduced in this chapter can perform all possible computations. The next section gives a brief history of computing machines, from prehistoric calculating aids to the design of the first universal computers. Section 6.2 ex- plains how machines can implement logic. Section 6.3 introduces a simple ab- stract model of a computing machine that is powerful enough to carry out any algorithm. We provide only a very shallow introduction to how machines can implement computations.

  • History of ENIAC
    A Short History of the Second American Revolution by Dilys Winegrad and Atsushi Akera (1) Today, the northeast corner of the old Moore School building at the University of Pennsylvania houses a bank of advanced computing workstations maintained by the professional staff of the Computing and Educational Technology Service of Penn's School of Engineering and Applied Science. There, fifty years ago, in a larger room with drab- colored walls and open rafters, stood the first general purpose electronic computer, the Electronic Numerical Integrator And Computer, or ENIAC. It spanned 150 feet in width with twenty banks of flashing lights indicating the results of its computations. ENIAC could add 5,000 numbers or do fourteen 10-digit multiplications in a second-- dead slow by present-day standards, but fast compared with the same task performed on a hand calculator. The fastest mechanical relay computers being operated experimentally at Harvard, Bell Laboratories, and elsewhere could do no more than 15 to 50 additions per second, a full two orders of magnitude slower. By showing that electronic computing circuitry could actually work, ENIAC paved the way for the modern computing industry that stands as its great legacy. ENIAC was by no means the first computer. In 1839, an Englishman Charles Babbage designed and developed the first true mechanical digital computer, which he described as a "difference engine," for solving mathematical problems including simple differential equations. He was assisted in his work by a woman mathematician, Ada Countess Lovelace, a member of the aristocracy and the daughter of Lord Byron. They worked out the mathematics of mechanical computation, which, in turn, led Babbage to design the more ambitious analytical engine.

  • Ada Lovelace's Calculation of Bernoulli's Numbers 1. Introduction
    Ada Lovelace's Calculation of Bernoulli's Numbers Ada Lovelace's Calculation of Bernoulli's Numbers Rainer Glaschick, Paderborn, Germany ([email protected]) http://rclab.de/analyticalengine/ 2016-09-29 1. Introduction In 1843, an article with the title Sketch of the Analytical Engine… [ML1843] was published, that contains an extensive and on its level fairly complete description of Charles Babbage's plans for a fully automatic computing engine. Its name has been motivated by the aim that it should be able to numerically solve all computations in the field of mathematical analysis (p.688): … all the Operations of analysis come within the domain of the engine. The article consists of a translation of a report by L.F. Menabrea, originally written in French, and supplements designated as Note A to Note G. The author was Augusta Ada King, Countess of Lovelace, who signed the Notes not by name, only with her initials A.A.L. — for the reasons her biographies should be consulted, that are also the place to the never-ending discussion about her mathematical ability, while this article strongly supports her excellence. The closing Note G got much attention, because the corresponding table now is regarded the first fairly complex program ever. The use of machine instructions, variables and a conditional loop is easily seen; but it is instructive to look into the very details of the program — which few people might have done, not only because several typos are not widely known (the most complete and reliable source seems to be [MCK1989], in particular see p.
