Download or read book Lee de Forest written by Mike Adams and published by Springer Science & Business Media. This book was released on 2011-10-17 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: The life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both invention and early film making; de Forest as the scientist and producer, director, and writer of the content. This book tells the story of de Forest’s contribution in changing the history of film through the incorporation of sound. The text includes primary source historical material, U.S. patents and richly-illustrated photos of Lee de Forest’s experiments. Readers will greatly benefit from an understanding of the transition from silent to audio motion pictures, the impact this had on the scientific community and the popular culture, as well as the economics of the entertainment industry.
Download or read book Lee de Forest and the Fatherhood of Radio written by James A. Hijiya and published by Lehigh University Press. This book was released on 1992 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book is not so much an analysis of de Forest's contribution to technology as it is a chronicle of his spiritual quest. Lee de Forest was an important inventor, and this biography attempts to explain what moved him to become one. It tries to show how - in a universe from which deity had seemingly disappeared - de Forest's devotion to invention was part of his search for a new light. The book is not a study in the history of technology but in the history of the religion of technology." "In 1906, de Forest created the "Audion," the three-electrode vacuum tube, which became the foundation of the electronics industry for half a century. He was a pioneer in radio and talking pictures, and he worked on projects ranging from television to solar energy. Holder of more than three hundred patents, he was one of the most prolific inventors in American history." "But he was more than that. Lee de Forest had an immense curiosity that extended beyond science and engineering to politics, literature, and religion. His active and far-ranging mind became a register for many social and intellectual events during his long life: from Populism to McCarthyism, and from Darwinism to agnosticism. But while his interests were diverse, his vision was not. For him invention was not merely a vocation but a worldview. He represented a technological progressivism that advocated reform, but reform stemming less from social engineering than from real engineering. Although he favored certain improvements in law and education, he did not think that these would be the basis of social transformation. Instead, he believed that inventions - ranging from radios to war planes - would reform the human condition and that the future was more in the hands of inventors than statesmen. The millenium would be a technical innovation, with himself as one of its principal inventors." "As a young man, de Forest came to spurn conventional notions of an immortal soul; but he never ceased to seek ways to overcome death - not merely the physical death of the body but also the spiritual death of living without purpose. The fame of his inventions would, he hoped, keep him forever alive in the memory of posterity. Moreover, the good that his inventions did for humanity - his contribution to progress - would give meaning to his existence. For Lee de Forest, then, invention was a substitute for religion. By helping to build the future, he sought to become an indelible part of it."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc. All Rights Reserved

Download or read book Wireless written by Sungook Hong and published by MIT Press. This book was released on 2010-01-22 with total page 267 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new look at the early history of wireless communication. By 1897 Guglielmo Marconi had transformed James Clerk Maxwell's theory of electromagnetic waves into a workable wireless telegraphy system, and by 1907 Lee de Forest had invented the Audion, a feedback amplifier and oscillator that opened the way to practical radio transmission. Fifteen years after Marconi's invention, wireless had become an essential means of communication, as well as a hobby for many. This book offers a new perspective on the early days of wireless communication. Drawing on previously untapped archival evidence and recent work in the history and sociology of science and technology, it examines the substance and context of both experimental and theoretical aspects of engineering and scientific practices in the first years of this technology. It offers new insights into the relationship between Marconi and his scientific advisor, the physicist John Ambrose Fleming (inventor of the vacuum tube). It includes the full story of the infamous 1903 incident in which Marconi's opponent Nevil Maskelyne interfered with Fleming's public demonstration of Marconi's syntonic (tuning) system at the Royal Institution by sending derogatory messages from his own transmitter. The analysis of the Maskelyne affair highlights the struggle between Marconi and his opponents, the efficacy of early syntonic devices, Fleming's role as a public witness to Marconi's private experiments, and the nature of Marconi's "shows." It also provides a rare case study of how the credibility of an engineer can be created, consumed, and suddenly destroyed. The book concludes with a discussion of de Forest's Audion and the shift from wireless telegraphy to radio.

Download or read book Charles Herrold Inventor of Radio Broadcasting written by Gordon Greb and published by McFarland. This book was released on 2015-09-11 with total page 259 pages. Available in PDF, EPUB and Kindle. Book excerpt: Still broadcasting today, the world's first radio station was invented by Charles Herrold in 1909 in San Jose, California. His accomplishment was first documented in a notarized statement written by him and published in the Electro-Importing Company's 1910 catalog: "We have given wireless phone concerts to amateur wireless men throughout the Santa Clara Valley." Being the first to "broadcast" radio entertainment and information to a mass audience puts him at the forefront of modern day mass communication. This biography of Charles Herrold focuses on how he used primitive technology to get on the air. Today it is a 50,000-watt station (KCBS, in San Francisco). The authors describe Herrold's story as one of early triumph and final failure, the story of an "everyman," an individual who was an innovator but never received recognition for his work and, as a result, died penniless. His most important work was done between 1912 and 1917, and following World War I, he received a license and operated station KQW for several years before running out of money. Herrold then worked as a radio time salesman, an audiovisual technician for a high school, and a janitor at a local naval facility, still telling anyone who would listen to him that he was the father of radio. The authors also consider some other early inventors, and the directions that their work took.

In the futuristic world of Indigo, reproduction is controlled by the government, guaranteeing that every baby is happy, healthy, and beautiful. But mistakes happen, and a rare few babies are accidentally born biologically, like Magdala Cled. Because of her natural-born features, Magdala is an outcast in society--abandoned at birth, abused in the orphanage she grew up in, and branded with the cruel name "Ugly." But Magdala's world turns upside down when she's approached by Claudio Loro, a wealthy scientist who has created a beautiful artificial body. When he offers to transfer Magdala's consciousness into the body, she cannot refuse the priceless opportunity for a new, beautiful life. However, unbeknownst to her, Claudio has crafted her new body to resemble Christophine del Jan, his rival scientist and former lover. Now Magdala must impersonate Christophine to infiltrate high society, court Claudio's advances, and decide whose side she is truly on--all while maintaining her real body lest it die...and she die with it.
Download or read book Signor Marconi s Magic Box written by Gavin Weightman and published by Da Capo Press. This book was released on 2009-06-16 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world at the turn of the twentieth century was in the throes of "Marconi-mania"-brought on by an incredible invention that no one could quite explain, and by a dapper and eccentric figure (who would one day win the newly minted Nobel Prize) at the center of it all. At a time when the telephone, telegraph, and electricity made the whole world wonder just what science would think of next, the startling answer had come in 1896 in the form of two mysterious wooden boxes containing a device one Guglielmo Marconi had rigged up to transmit messages "through the ether." It was the birth of the radio, and no scientist in Europe or America, not even Marconi himself, could at first explain how it worked -- it just did. And no one knew how far these radio waves could travel, until 1903, when a message from President Theodore Roosevelt to the king of England flashed from Cape Cod to Cornwall clear across the Atlantic.Here is a rich portrait of the man and his era-and a captivating tale of science and scientists, business and businessmen. There are stories of British blowhards, American con artists-and Marconi himself: a character par excellence, who eventually winds up a virtual prisoner of his worldwide fame and fortune.

Download or read book Of Dogs and Other People written by Susan Landauer and published by Univ of California Press. This book was released on 2017-04-15 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Roy De Forest's brightly colored, crazy-quilted jungles dotted with nipples of paint and inhabited by a cast of characters uniquely his own (a perennial favorite being his wild-eyed, pointy-eared dogs) appeal to a broad spectrum of viewers from young to old, from the casual visitor to the most sophisticated art aficionado. OMCA's project aims to reassess De Forest's art-historical position, placing him in a national rather than solely regional/West Coast context. Landauer positions De Forest as part of a bicoastal alternative current of American art that has been poorly documented and deliberately ran counter to better publicized tendencies of the 1960s and 1970s, notably Pop, Minimalism, and post-painterly abstraction. Despite the playfulness of his work, close study of De Forest's art reveals deep layers of meaning. He was a fan of popular science fiction and adventure stories, but he was also well versed in Australian aboriginal art, ukiyo-e prints, poetry, literature, and the history of philosophy. He enjoyed secreting obscure art-historical references into his work: animals might assume postures found in Medieval or Renaissance art, or a drawing that appears to depict a comic-book character may in fact refer to Titian's triple-headed allegory of Prudence. This engaging publication presents gorgeous color reproductions of 150 of De Forest's finest artworks, plus a variety of figure illustrations that illuminate the artist's diverse sources and freewheeling social and creative milieu in Northern California."--Provided by publisher.

Download or read book Blood Traces written by Peter R. De Forest and published by John Wiley & Sons. This book was released on 2021-08-09 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the scientific interpretation of blood traces Blood Traces provides an authoritative resource that reviews many of the aspects of the interpretation of blood traces that have not been treated with the thoroughness they deserve. With strict adherence to the scientific method, the authors — noted experts on the topic — address the complexities encountered when interpreting blood trace configurations. The book provides an understanding of the scientific basis for the use of blood trace deposits, i.e. bloodstain patterns, at crime scenes to better reconstruct a criminal event. The authors define eight overarching principles for the comprehensive analysis and interpretation of blood trace configurations. Three of these principles are: blood traces may reveal a great deal of useful information; extensive blood traces, although present, may not always yield information relevant to questions that may arise in a given case; and a collection of a few seemingly related dried blood droplet deposits is not necessarily an interpretable “pattern”. This important resource: Provides the fundamental principles for the scientific examination and understanding of blood trace deposits and configurations Dispels commonly accepted misinformation about blood traces. Contains a variety of illustrative case examples which will aid in demonstrating the concepts discussed Written for forensic scientists, crime scene investigators, members of the legal community, and students in these fields, Blood Traces presents the fundamental principles for the scientific examination of blood trace deposits and configurations.
