Anne Glyn-Jones opens up the secret world of the interceptors of German Morse Code signals during World War II. Leaving her girls' boarding school with romantic ideas about joining the navy as a Wren, Anne had no idea that she would be working for the mysterious 'Station X', which we now know to be Bletchley Park. Round the clock shifts, bed bugs, rats and poor diet took its toll, as well as the ongoing lack of recognition from the Navy hierarchy. Morse Code Wrens of Station X is a very personal memoir of a young woman's experiences of war time service, as well as providing fascinating insights into the daily realities of the battle for military intelligence superiority.
In the seven decades from its establishment in 1775 to the commercialization of the electric telegraph in 1844, the American postal system spurred a communications revolution no less far-reaching than the subsequent revolutions associated with the telegraph, telephone, and computer. This book tells the story of that revolution and the challenge it posed for American business, politics, and cultural life. During the early republic, the postal system was widely hailed as one of the most important institutions of the day. No other institution had the capacity to transmit such a large volume of information on a regular basis over such an enormous geographical expanse. The stagecoaches and postri...
In this history of new media technologies, leading media and cultural theorists examine new media against the background of traditional media such as film, photography, and print in order to evaluate the multiple claims made about the benefits and freedom of digital media.
Hosea Ballou Morse (1855-1934) sailed to China in 1874, and for the next thirty-five years he labored loyally in the Imperial Chinese Maritime Customs Service, becoming one of its most able commissioners and acquiring a deep knowledge of China's economy and foreign relations. After his retirement in 1909, Morse devoted himself to scholarship. He pioneered in the Western study of China's foreign relations, weaving from the tangled threads of the Ch'ing dynasty's foreign affairs several seminal interpretive histories, most notably his three-volume magnum opus, The International Relations of the Chinese Empire (1910-18). At the time of his death, Morse was considered the major historian of mode...

Finite-dimensional Morse theory is easier to present fundamental ideas than in infinite-dimensional Morse theory, which is theoretically more involved. However, finite-dimensional Morse theory has its own significance. This volume explains the finte-dimensional Morse theory.
When Philip Morse was promoted to Professor Emeritus of Physics at M.I.T. in 1969, he already had behind him at least three full professional careers--in Quantum physics, in acoustics, and in what Julius Stratton calls "the reduction of theory to numerically useful results," a general field of which Morse was a founder and for which no good term yet exists, that includes operations research, machine computation, and systems analysis. This volume contains papers in all these fields, written by Professor Morse's students and colleagues. By their presence here, they gratefully testify to the influence that Philip Morse has had on their work and, in many cases, on their lives.
