Babbage as a computer pioneer

AbstractThis paper is primarily concerned with Babbage's plans for the Analytical Engine. It is based on an examination of Babbage's surviving notebooks and drawings and includes much unpublished material on the “directive part” of the engine—what would now be called the control. The paper ends with an evaluation of Babbage's work in the light of modern developments

On The Foundations of Digital Games

Computers have lead to a revolution in the games we play, and, following this, an interest for computer-based games has been sparked in research communities. However, this easily leads to the perception of a one-way direction of influence between that the field of game research and computer science. This historical investigation points towards a deep and intertwined relationship between research on games and the development of computers, giving a richer picture of both fields. While doing so, an overview of early game research is presented and an argument made that the distinction between digital games and non-digital games may be counter-productive to game research as a whole

What is a Robot?

A robot is a mechanical hand and arm, controlled by a computer. It is nothing more than another type of machine. Its ancestry combines two different, but related, technologies: mechanisation and control. The history of the computer has been essential to both. The history of mechanisation began with Oliver Evans' automated mill (1784), continued with Joseph Jacquard's loom (1801), and reached a high state of perfection at the end of the nineteenth century with Steward Babbitt's designs for a motorised crane which had a mechanical gripper to remove ingots from furnaces (1892). In the 1820s the technology of mechanisation cross-fertilised with the emerging science of information and control technology when the English mathematician, Charles Babbage, sometimes known as 'the father of the computer', developed an automatic calculator which he called his 'Difference Engine' (1823). Joseph Jacquard's loom proved to be the plateau from which all subsequent innovations in mechanisation and control took off. His invention was software, the novel idea that you could program a weaver's loom with punched cards that carried a coded 'model' of the patterns being woven. The Jacquard loom appeared in 1801, the last and most significant of a series of innovations in silk weaving which came out of Lyons from the early nineteenth century. It was so successful that by 1812 there were more than 11,000 in France alone. The punched card was a breakthrough in information technology: a Jacquard loom could carry as much as three megabytes of information on perforated paper. This technique of information storage became one of the fundamental components of the automatic memory calculators which gave birth to computers

Philosophers and artisans : the relationship between men of science and instrument makers in London 1820-1860

This thesis examines the changed status of the instrument maker in the London-based scientific community of the nineteenth century, compared with the eighteenth century, and seeks to account for the difference. Chapter 1 establishes that the eighteenth-century maker could aspire to full membership of the scientific community. The following chapters show that this became impossible by the period 1820-1860. Among reasons suggested for the change are that the instrument maker's educational context to some extent precluded him from contributing to scientific innovation, and also the changed market for his products in an industrial Britain required that he devote more time to his business, thus decreasing the time available to pursue new developments. However, the decline is attributed mainly to the tendency of the scientific community to refine its own criteria of membership, in an era in which its self-consciousness as a distinct group increased, and its members articulated claims to status in terms of their value to the State. This ideology and its consequences are analysed in a number of studies. Chapter 2 deals with the burgeoning of collective identity in the context of the Royal Society, while the next four chapters study individual members of the scientific elite - Wheatstone, Babbage, Airy and Faraday, and their relationships with instrument makers. The studies demonstrate that the philosopher recognised the artisan's work as important, but not as vital as his own, and not classifiable as scientific work. As an institutional manifestation of the motives of the leading philosophers, the B.A.A.S. is the focus of Chapter 7. The final case study centres on the maker's tactics of self-promotion in business terms, thus linking more fully the factors at work in ensuring the rise of the philosopher and the decline in status of the artisan in the scientific community

A di alogue logic

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Architecture, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 63-66).The history of computation owes a major debt to the traditional crafts, and the worlds of design and computation have been interlinked since the development of mechanical computing systems during the 19 th century. As computing systems became digital, the connections between craft and computation have become more abstract, though they are still there. The regime between the analogue world of craft, and more generally design practice, and the digital world of computation, here referred to as the "di-alogue" world has barely been explored. By challenging our notions of both craft and computation, how can excursions into the di alogue world help us to re-define or re-conceive of our traditional understanding of craft and of computation? In this thesis, I examine the shared history of traditional craft and computation as well as cover several examples of how these worlds have been combined. Additionally, I argue that by capitalizing on the procedural backbone of a particular craft, one can create unique "logics" that blur the perceived line between craft and computation.by Henry George Skupniewicz.S.B

Complexity, Reliability, and Design: Manufacturing Implications (Revised Version)

A major component of IIASA's Technology-Economy-Society (TES) Program is a project to assess "Computer Integrated Manufacturing" (CIM), by which is meant the whole range of application of computers to discrete parts manufacturing and assembly. The various familiar acronyms and buzzwords, such as NC, CNC, DNC, CAD/CAM robotics, FMS, "group technology" and MRP all fit under the broad CIM umbrella. The present paper is the first to be generated, at least in part, under the project. (In fact, an earlier draft was written while the author was at Carnegie-Mellon University). The paper presents some interesting and new ideas about the nature of the forces driving the worldwide trend toward flexible automation. It suggests, in brief, that the demand for CIM arises from what Nathan Rosenberg has termed as "mismatch", i.e. a problem that was created, in effect, by technological progress itself. In this case the "problem" is that defects in manufacturing have become intolerable. The reason for that is that demand for higher and higher levels of product performance, over many decades, has required orders-of-magnitude increases in mechanical complexity, on the one hand, and higher precision, on the other. To satisfy these high standards requires a level of error control that increasingly precludes the use of human workers in direct contact with workpieces as they move through the manufacturing system. This working paper is being made available more widely to stimulate discussion and comment. We hope that it will succeed in that regard
