What all of these separate devices have in common is the same core technological mechanism and mode of action—the mapping of differences along a surface to be known by a lensless apparatus that detects via probe-signals. Despite being mobilized to very different uses and within a large diversity of networks and media assemblages, scanners arise from a common genealogical source—the conceptual union of photography to telegraphy. Scanners appear everywhere in our modern infrastructure. It is impossible to avoid these devices, as they mediate even the most basic transactions in everyday life, such as purchasing food at the grocery store or checking out a book at a college library. Yet neither historians of technology nor media scholars have addressed this quotidian device which enables so much of modern bureaucracy in business, government and education to function. While the scanner’s absence from the landscape of critical thought precisely marks the problem of the unremarkable in vi our scholarship, the metaphor of scanning remains present in both common and scholarly discourse. Scanning may, at various times, stand in for a model of attention, a form of reading, or serve as a simile for searching and/or diagnosing. The imagination of the scan well precedes its appearance as a technology, which further indicates the necessity of understanding this unexamined medium. This dissertation project investigates the object of the scanner as a term for organizing the imagination and materialization of an entire suite of technologies that we encounter daily. Conceived as a social history of technology married to a film and media studies paradigm, this dissertation examines the scanner as a form of machine-perception that, while it extends the dominant conception of the camera-prosthesis, stands as its own unique model of perceptual mediation. The scanner remains unique in media studies because so much of its identity depends upon the place it holds within the historical conditions of the intermedial assemblage in which it has been mobilized. Through a series of case studies in which I loosely divide scanning technologies into genres of perceptual and epistemological function, I triangulate the epistemic role of the scanner in each of its respective media networks. vii TABLE OF CONTENTS Introduction 1 Chapter 1 – Television Before TV: Scanner Technologies & the Origins of Images-at- 35 a-Distance Chapter 2 – Material Histories of Visualization: Particle Accelerators and the 69 Epistemologies of Discovery Chapter 3 – The Material of Information: an Intermedial History of Barcode Scanning 104 and the Genesis of Automated Identification and Data Collection Chapter 4 – Archiving the Gesture: Motion Tracking and Scanning at the Limits 152 Conclusion 188 References 198 viii LIST OF FIGURES Figure 1.

Diagram of scans involved in Amazon package reaching customer . 140 ix Introduction The earliest known use of the word “scan” in the English language was in 1398: the verb, “to scan,” meant “to mark up poetry for recitation.”1 Scanning thus began its conceptual life as a process of ephemeral inscription, of analytical judgment in relation to textual practices. By approximately 1550, the verb would take on a new meaning. It would mean to “criticize; to test or estimate the correctness or value of; to judge by a certain rule or standard.” This notion of scanning as an evaluative form would lead into its subsequent meaning, “to examine, consider, or discuss minutely.”2 A scanner became “one who scans or examines critically.” This human-centered usage denoted a person who was capable of deciphering the smallest details that escaped others, searching almost in a forensic mode. Over the years, to scan also came to variously mean to perceive, to interpret or assign meaning, or to search or examine in a searching manner with the eyes. These somewhat rare definitions of scanning are no longer in use today, but nonetheless haunt the modern understanding of scanning, especially the notion of perception and the assignation of meaning. Eventually, scanning would come to mean looking over a text quickly with one’s eyes. Not until 1927 would the term scanner come to be associated with a scanning machine, “any device for scanning or examining all parts of something.”3 Once scanning became the function of a machine, the changing definition of the verb “to scan” remained concerned with the act of examination, scrutiny and the attendant issues that come with such an endeavor. Although visual practices of scanning preceded the invention of the scanner, the process of scanning remains involved in seeking out differences and making distinctions. 1 Oxford English Dictionary, 2nd ed., s.v. “Scan.” 2Ibid. 3 Ibid 1 This project studies the unique mediating process of machine scanning and the role it plays in today’s media ecology. Serving as a relay point in larger systems of media, scanners act as an interface that transforms material objects into virtual information. The scanner serves various functions, such as visualization, verification, and detection of objects, through the mechanism of measurement and quantification. When understood as its own mediating process, an examination of scanning reveals a buried set of ideological and epistemological functions that serve larger systems of command and control. By examining the process of scanning through a critical media studies paradigm, the following four chapters uncover the ways in which the mediating process of scanning shapes communication and the parameters of what can and cannot be known. In this project, I define scanning as a process of social and technical measurement that orbits at all times a machine nucleus called the scanner. This machine has taken on many guises over time, and its changes in form, and adaptation to its environment, have in turn shaped the process of scanning in each iteration. For this reason, the machine remains a necessary part of the definition of scanning as the function of scanning has become progressively

  • Letter from Alexander Graham Bell to Alexander Melville Bell, February 26, 1880, with Transcript
    Library of Congress Letter from Alexander Graham Bell to Alexander Melville Bell, February 26, 1880, with transcript ALEXANDER GRAHAM BELL TO HIS FATHER A. MELVILLE BELL 904 14th Street, N. W., Washington, D. C. Feb. 26th, 1880. Dear Papa: I have just written to Mamma about Mabel's baby and I now write to you about my own! Only think! — Two babies in one week! The first born at 904 14th Street — on the fifteenth inst., the other at my laboratory on the nineteenth. Both strong vigorous healthy young things and both destined I trust to grow into something great in the future. Mabel's baby was light enough at birth but mine was LIGHT ITSELF! Mabel's baby screamed inarticulately but mine spoke with distinct enunciation from the first. I have heard articulate speech produced by sunlight! I have heard a ray of the sun laugh and cough and sing! The dream of the past year has become a reality — the “ Photophone ” is an accomplished fact. I am not prepared at present to go into particulars and can only say that with Mr. Tainter's assistance I have succeeded in preparing crystalline selenium of so low a resistance and so sensitive to light that we have been enabled to perceive variations of light as sounds in the telephone. In this way I have been able to hear a shadow, and I have even perceived by ear the passage of a cloud across the sun's disk. Can Imagination picture what the future of this invention is to be! I dream of so many important and wonderful applications that I cannot bring myself to make known my discovery — until I have demonstrated the practicability of some of these schemes.

  • Alexander Graham Bell
    WEEK 2 LEVEL 7 Alexander Graham Bell Alexander Graham Bell is the famous inventor of the telephone. Born in Scotland on March 3, 1847, he was the second son of Alexander and Eliza Bell. His father taught students the art of speaking clearly, or elocution, and his mother played the piano. Bell’s mother was almost deaf. His father’s career and his mother’s hearing impairment influenced the course of his career. He became a teacher of deaf people. As a child, Bell didn’t care for school, and he eventually dropped out. He did like to solve problems though. For example, when he was only 12, he invented a new farm implement. The tool removed the tiny husks from wheat grains. After the deaths of his two brothers from tuberculosis, Bell and his parents moved from Europe to Canada in 1870. They thought the climate there was healthier than in Scotland. A year later, Bell moved to the United States. He got a job teaching at the Boston School for Deaf Mutes. © 2019 Scholar Within, Inc. WEEK 2 LEVEL 7 One of his students was a 15-year-old named Mabel Hubbard. He was 10 years older than she was, but they fell in love and married in 1877. The Bells raised two daughters but lost two sons who both died as babies. Bell’s father-in-law, Gardiner Hubbard, knew Bell was interested in inventing things, so he asked him to improve the telegraph. Telegraph messages were tapped out with a machine using dots and dashes known as Morse code.

  • Fax Machine (Edited from Wikipedia)
    Fax Machine (Edited from Wikipedia) SUMMARY Fax (short for facsimile), sometimes called telecopying or telefax, is the telephonic transmission of scanned printed material (both text and images), normally to a telephone number connected to a printer or other output device. The original document is scanned with a fax machine (or a telecopier), which processes the contents (text or images) as a single fixed graphic image, converting it into a bitmap (a kind of digital image file), and then transmitting it through the telephone system in the form of audio-frequency tones. The receiving fax machine interprets the tones and reconstructs the image, printing a paper copy. Early systems used direct conversions of image darkness to audio tone in a continuous or analog manner. Since the 1980s, most machines modulate the transmitted audio frequencies using a digital representation of the page which is compressed to quickly transmit areas which are all-white or all-black. HISTORY Scottish inventor Alexander Bain worked on chemical mechanical fax type devices and in 1846 was able to reproduce graphic signs in laboratory experiments. He received British patent 9745 on May 27, 1843 for his "Electric Printing Telegraph." Frederick Bakewell made several improvements on Bain's design and demonstrated a telefax machine. The Pantelegraph was invented by the Italian physicist Giovanni Caselli. He introduced the first commercial telefax service between Paris and Lyon in 1865, some 11 years before the invention of the telephone. In 1880, English inventor Shelford Bidwell constructed the scanning phototelegraph that was the first telefax machine to scan any two-dimensional original, not requiring manual plotting or drawing.

  • Extending Korn's First Inequality to Incompatible Tensor Fields
    Poincare´ meets Korn via Maxwell: Extending Korn's First Inequality to Incompatible Tensor Fields Patrizio Neff, Dirk Pauly, Karl-Josef Witsch May 14, 2014 Dedicated to Rolf Leis on the occasion of his 80th birthday Abstract 3 For a bounded domain Ω ⊂ R with Lipschitz boundary Γ and some relatively open Lipschitz subset Γt 6= ; of Γ, we prove the existence of some c > 0, such that c jjT jj 2 3×3 ≤ jjsym T jj 2 3×3 + jjCurl T jj 2 3×3 (0.1) L (Ω;R ) L (Ω;R ) L (Ω;R ) holds for all tensor fields in H(Curl; Ω), i.e., for all square-integrable tensor fields 3×3 3×3 T :Ω ! R with square-integrable generalized rotation Curl T :Ω ! R , having vanishing restricted tangential trace on Γt. If Γt = ;, (0.1) still holds at least for simply connected Ω and for all tensor fields T 2 H(Curl; Ω) which are L2(Ω)-perpendicular to so(3), i.e., to all skew-symmetric constant tensors. Here, both operations, Curl and tangential trace, are to be understood row-wise. For compatible tensor fields T = rv, (0.1) reduces to a non-standard variant of 3 the well known Korn's first inequality in R , namely c jjrvjj 2 3×3 ≤ jjsym rvjj 2 3×3 L (Ω;R ) L (Ω;R ) 1 3 for all vector fields v 2 H (Ω; R ), for which rvn, n = 1;:::; 3, are normal at Γt. On 1 3 arXiv:1203.2744v3 [math.AP] 13 May 2014 the other hand, identifying vector fields v 2 H (Ω; R ) (having the proper boundary conditions) with skew-symmetric tensor fields T , (0.1) turns to Poincar´e's inequality since p 2c jjvjj 2 3 = c jjT jj 2 3×3 ≤ jjCurl T jj 2 3×3 ≤ 2 jjrvjj 2 3 : L (Ω;R ) L (Ω;R ) L (Ω;R ) L (Ω;R ) Therefore, (0.1) may be viewed as a natural common generalization of Korn's first and Poincar´e'sinequality.

  • Visions of Electric Media Electric of Visions
    TELEVISUAL CULTURE Roberts Visions of Electric Media Ivy Roberts Visions of Electric Media Television in the Victorian and Machine Ages Visions of Electric Media Televisual Culture Televisual culture encompasses and crosses all aspects of television – past, current and future – from its experiential dimensions to its aesthetic strategies, from its technological developments to its crossmedial extensions. The ‘televisual’ names a condition of transformation that is altering the coordinates through which we understand, theorize, intervene, and challenge contemporary media culture. Shifts in production practices, consumption circuits, technologies of distribution and access, and the aesthetic qualities of televisual texts foreground the dynamic place of television in the contemporary media landscape. They demand that we revisit concepts such as liveness, media event, audiences and broadcasting, but also that we theorize new concepts to meet the rapidly changing conditions of the televisual. The series aims at seriously analyzing both the contemporary specificity of the televisual and the challenges uncovered by new developments in technology and theory in an age in which digitization and convergence are redrawing the boundaries of media.
