Lost Knowledge


Book Description

Lost Knowledge: The Concept of Vanished Technologies and Other Human Histories examines the idea of lost knowledge, reaching back to a period between myth and history. It investigates a peculiar idea found in a number of early texts: that there were civilizations with knowledge of sophisticated technologies, and that this knowledge was obscured or destroyed over time along with the civilization that had created it. This book presents critical studies of a series of early Chinese, South Asian, and other texts that look at the idea of specific “lost” technologies, such as mechanical flight and the transmission of images. There is also an examination of why concepts of a vanished “golden age” were prevalent in so many cultures. Offering an engaging and investigative look at the propagation of history and myth in technology and culture, this book is sure to interest historians and readers from many backgrounds.




The Cosmic Inventor


Book Description

This is a print on demand publication. A study of the inventor Reginald A. Fessenden who was born in 1866 in Canada. Although the core of his more public fame rests on his seminal contributions to wireless, the more than 200 patents he was granted cover an amazing range. In addition, Fessenden developed the concept of what is today termed amplitude modulated (AM) radio. He produced and improved upon equipment to demonstrate the principles involved, being the first individual to transmit voice and music over the air. He was the first to establish consistent two-way wireless commun. across the Atlantic Ocean. In the course of his wireless work, he was granted a patent for use of the heterodyne principle that became so important in the vacuum tube era of radio and beyond. Illus.







Studies in Medieval Georgian Historiography


Book Description

Original literature first appeared among the indigenous population of Caucasia in the fifth century AD as a consequence of its Christianization. Though a number of Armenian histories were composed at this time, several centuries elapsed before the Georgians created their own. But how many centuries? Through a meticulous investigation of internal textual criteria, Studies in Medieval Georgian Historiography challenges the traditional eleventh-century dating of the oldest Georgian narrative histories and probes their interrelationships. Illuminating Caucasia's status as a cultural crossroads, it reveals the myriad Eurasian influences - written and oral, Christian and non-Christian - on these "pre-Bagratid" histories produced between the seventh and the ninth century. Eastern Georgia's place in the Eurasian world and its long-standing connection to the Iranian Commonwealth are specially highlighted. This volume also examines several related historical and historiographical problems of the early Bagratid period and supplies critical translations of six early Georgian histories previously unavailable in English. Dr. Stephen H. Rapp, Jr. is Assistant Professor of History at Georgia State University, Atlanta (USA), and is the Founding Director of its Program in World History and Cultures.
