Book excerpt: Excerpt from The Speaking Telephone, Electric Light and Other Recent Electrical InventionsWithin a short time past, a very extended application of elec tricity to illuminating purposes has been made, both in this country and abroad, and just new public interest in this matter is very much excited. It was a long time after Davy's discovery, that the electric current was capable of producing the most brilliant light, before the thought was seriously entertained of putting this agency to practical use as a light producing power. But with the introduction of N ollet's improved magneto-electric machines the thing soon became an accomplished fact, by which the solution of the great problem is to be attained Later and more efficient machines have rendered this application of elec tricity much more feasible, and today its field of usefulness for certain purposes is as clearly defined as that of steam itself. Whether the further introduction of electricity for domestic lighting will realize the expectations of many who are at present studying the subject, remains yet to be seen. The economical side of the problem is still a debatable subject, and one also of very general interest, so that it is not at all surprising, consider ing what has already been accomplished, that the public gives easy credence to many extravagant statements made with regard to it.How much ground there may be for the anticipations of suc cess which are so sanguinely indulged in by friends and pro moters of the new light it would be difficult to say, as consider able secrecy is properly maintained in regard to the devices at present. What has been said on the general subject in the chapters on electric lighting will, however, give the reader a fair knowledge of what has already been done, and thus enable him to judge with some degree of confidence what probability of success there is in prospect in the immediate future.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book The Telegraph in America 1832 1920 written by David Hochfelder and published by JHU Press. This book was released on 2013-01-01 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete history of how the telegraph revolutionized technological practice and life in America. Telegraphy in the nineteenth century approximated the internet in our own day. Historian and electrical engineer David Hochfelder offers readers a comprehensive history of this groundbreaking technology, which employs breaks in an electrical current to send code along miles of wire. The Telegraph in America, 1832–1920 examines the correlation between technological innovation and social change and shows how this transformative relationship helps us to understand and perhaps define modernity. The telegraph revolutionized the spread of information—speeding personal messages, news of public events, and details of stock fluctuations. During the Civil War, telegraphed intelligence and high-level directives gave the Union war effort a critical advantage. Afterward, the telegraph helped build and break fortunes and, along with the railroad, altered the way Americans thought about time and space. With this book, Hochfelder supplies us with an introduction to the early stirrings of the information age.

Download or read book When Old Technologies Were New written by Carolyn Marvin and published by Oxford University Press. This book was released on 1990-05-24 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the history of electronic communication, the last quarter of the nineteenth century holds a special place, for it was during this period that the telephone, phonograph, electric light, wireless, and cinema were all invented. In When old Technologies Were New, Carolyn Marvin explores how two of these new inventions--the telephone and the electric light--were publicly envisioned at the end of the nineteenth century, as seen in specialized engineering journals and popular media. Marvin pays particular attention to the telephone, describing how it disrupted established social relations, unsettling customary ways of dividing the private person and family from the more public setting of the community. On the lighter side, she describes how people spoke louder when calling long distance, and how they worried about catching contagious diseases over the phone. A particularly powerful chapter deals with telephonic precursors of radio broadcasting--the "Telephone Herald" in New York and the "Telefon Hirmondo" of Hungary--and the conflict between the technological development of broadcasting and the attempt to impose a homogenous, ethnocentric variant of Anglo-Saxon culture on the public. While focusing on the way professionals in the electronics field tried to control the new media, Marvin also illuminates the broader social impact, presenting a wide-ranging, informative, and entertaining account of the early years of electronic media.

Download or read book Inventive Minds written by Robert John Weber and published by Oxford University Press, USA. This book was released on 1992 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Is invention really "99 percent" perspiration and "one percent inspiration" as Thomas Edison assured us? Inventive Minds assembles a group of authors well equipped to address this question: contemporary inventors of important new technologies, historians of science and industry, and cognitive psychologists interested in the process of creativity. In telling their stories, the inventors describe the origins of such remarkable devices as ultrasound, the electron microscope, and artificial diamonds. The historians help us look into the minds of innovators like Thomas Edison, Alexander Graham Bell, Michael Faraday, and the Wright brothers, drawing on original notebooks and other sources to show how they made their key discoveries. Finally, cognitive psychologists explore the mental processes that figure in creative thinking. Contributing to the authors' insight is their special focus on the "front end" of invention -- where ideas come from and how they are transformed into physical prototypes. They answer three questions: How does invention happen? How does invention contrast with other commonly creative pursuits such as scientific inquiry, musical composition, or painting? And how might invention best happen -- that is, what kinds of settings, conditions, and strategies appear to foster inventive activity? The book yields a wealth of information that will make absorbing reading for cognitive and social psychologists, social historians, and many working scientists and general readers who are interested in the psychology of personality and the roots of ingenuity.

Download or read book AC DC written by Tom McNichol and published by John Wiley & Sons. This book was released on 2011-01-06 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: AC/DC tells the little-known story of how Thomas Edison wrongly bet in the fierce war between supporters of alternating current and direct current. The savagery of this electrical battle can hardly be imagined today. The showdown between AC and DC began as a rather straightforward conflict between technical standards, a battle of competing methods to deliver essentially the same product, electricity. But the skirmish soon metastasized into something bigger and darker. In the AC/DC battle, the worst aspects of human nature somehow got caught up in the wires; a silent, deadly flow of arrogance, vanity, and cruelty. Following the path of least resistance, the war of currents soon settled around that most primal of human emotions: fear. AC/DC serves as an object lesson in bad business strategy and poor decision making. Edison's inability to see his mistake was a key factor in his loss of control over the ?operating system? for his future inventions?not to mention the company he founded, General Electric.
