Book Synopsis The Telegraph in America, 1832–1920 by : David Hochfelder
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.

Book Synopsis American Telegraph Practice by : Donald McNicol
Download or read book American Telegraph Practice written by Donald McNicol and published by . This book was released on 2015-07-26 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from American Telegraph Practice: A Complete Technical Course in Modern, Telegraphy, Including Simultaneous Telegraphy and Telephony In this work the aim has been to give a detailed exposition of the various systems of telegraphy in use in America at the present time, together with a complete description of modern methods of operation, and an extensive compilation of the formulae used in practical telegraphy. One occasionally hears it remarked that since the practical introduction of the quadruplex about thirty years ago there have been no important developments in telegraphy, but those who have been engaged in the work of improving telegraph apparatus and operating methods are well aware that even since the last American book dealing with this subject was written several years ago, material progress has been made in several directions. The fact that to-day eighty telegrams per hour are handled over a single Morse outlet where ten years ago half that number in the same time was considered good performance, and that during the same period the time of transmission of a telegram between cities remotely separated has been reduced at least one-half, cannot but be regarded as convincing evidence that vast improvement has taken place. One factor that has contributed largely to the improvement in the service is the increasing technical knowledge of the men engaged in operating the plant; and this, in spite of the fact that the production of technical telegraph literature has not kept pace with the actual development of the art. In the present work the author has incorporated all of the elemental essentials of the general subject as well as all of the new departures which have made for betterment, and an attempt has been made to treat the various divisions of the subject in terms that should make it possible for the student, by due exercise of diligence, to qualify himself for the most advanced positions in the service. Incidentally, it might here be stated that it is no longer possible for the telegrapher to make much headway in the service without an understanding of arithmetic and elementary algebra, and, while usually mathematical formulae are regarded as being incomprehensible, by those who have not had the advantages of high school education, the author believes that as herein employed and worked out, all of the required mathematics may be mastered without difficulty.

Book excerpt: Samuel F.B. Morse's invention of the telegraph marked a new era in communication. For the first time, people were able to communicate quickly from great distances. The genesis of Morse's invention is covered in detail, starting in 1832, along with the establishment of the first transcontinental telegraph line in the United States and the dramatic effect the device had on the Civil War. The Morse telegraph that served the world for over 100 years is explained in clear terms. Also examined are recent advances in telegraph technology and its continued impact on communication.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Wireless Telegraphy The decisive turning-point was reached in 1896, by the labours of Guglielmo Marconi, who made a definite attempt to elaborate a system of wireless telegraphy by means of electric waves. True, he stood upon the secure foundation of the ingenious experiments of Hertz; but the persistence and skill with which he contrived to overcome the practical difficulties in his way, cannot be sufficiently admired. Thus Marconi was the first to actually telegraph over a distance of many miles without wires, thereby winning lasting renown. However, the capacity of his instruments soon reached a limit. In Germany, too, the labours of slaby-arco led to no improvement, in point of principle; but the course of development was diverted into an entirely new channel with unexpected progress by the work of Professor Ferdinand Braun, of Strassburg. By complete mastery of the existing material, well-designed application of scientific principles and appropriate use of technical appliances, he created the basis on which wireless telegraphy is now everywhere conducted. To the personal modesty of Professor Braun nothing is more objectionable than the fruitless conflict over the so called systems: and he would be the first to put an end to the envious and distracting outcry raised by the companies engaged in exploiting wireless telegraphy, and to use the name Hertzian electrical-wave Telegraphy as the worthiest title possible.
