Description : Excerpt from English Mechanic and World of Science, 1882, Vol. 34: With Which Are Incorporated "the Mechanic, "Scientific Opinion," and "the British and Foreign Mechanic" The single-needle telegraph is not used over here. Bregnet's A BC telegraph is the sim plest of these instruments. The manipulator consists of a horizontal bran dial, on which the letters of the alphabet are written to each letter correspondsanotch onthecircumferenceof the dial. A handle is movable around this dial, and is turned until a stud which pro'eots under the handle drops into the notch of t e letter which we wish to send. This handle makes and breaks the current by means of a wheel with curved teeth. The receiving instrument has an ABC dial, whose needle is made to turn round by clockwork, the escapement being releued by an electro-magnet each time the current passes. In Hughes's printing the sending instrument a key e a piano, on whose keys are written the letters of the alphabet. The essential part of the receiver is a type-wheel against which the slip of paper is pressed (each time a) key1 g the sendin instxl'oument is pressed an e co n g tter prin u nthepaper. This egra bbss very oom pezated mechanism, and al&ough at a first glance it may look simple to work, yet it is not or the type-wheel turning, say, onceina second, time must be carefully ke t to this. It is much used in France. Baudot s instrument takes up much less room; but is also very complicated. It will tint six messages at a time.

Description : Noakes' revelatory analysis of Victorian scientists' fascination with psychic phenomena connects science, the occult and religion in intriguing new ways.
Description : James Mussell engages with nineteenth-century scientific writing and recent theoretical discussion to propose a new methodology that situates the periodical press in space and time. Well-known writers like H. G. Wells and Arthur Conan Doyle are discovered in new contexts, while other authors, publishers, editors, and scientists are discussed in ways that inform current debates about the status of digital publication and the preservation of archival material in electronic forms.
Description : The book about John Michell (1724-93) has two parts. The first and longest part is biographical, an account of Michell’s home setting (Nottinghamshire in England), the clerical world in which he grew up (Church of England), the university (Cambridge) where he studied and taught, and the scientific activities he made the center of his life. The second part is a complete edition of his known letters. Half of his letters have not been previously published; the other half are brought together in one place for the first time. The letters touch on all aspects of his career, and because they are in his words, they help bring the subject to life. His publications were not many, a slim book on magnets and magnetism, one paper on geology, two papers on astronomy, and a few brief papers on other topics, but they were enough to leave a mark on several sciences. He has been called a geologist, an astronomer, and a physicist, which he was, though we best remember him as a natural philosopher, as one who investigated physical nature broadly. His scientific contribution is not easy to summarize. Arguably he had the broadest competence of any British natural philosopher of the eighteenth century: equally skilled in experiment and observation, mathematical theory, and instruments, his field of inquiry was the universe. From the structure of the heavens through the structure of the Earth to the forces of the elementary particles of matter, he carried out original and far-reaching researches on the workings of nature.
Description : When the BBC launched the world's first regular, high-definition television service on 2 November, 1936 it was the culmination of decades of technological innovations. More than this, however, the service meant that the principle of television had finally found its place. The Birth of British Television – A History traces the early history and development of television, from the experiments of amateurs to the institutionalised developments that led to the world's first regular, high definition television service. Author Mark Aldridge provides a clear, in-depth and accessible introduction for those either exploring the period for the first time or seeking new insights into the beginnings of the industry. In tracing the origins and development of television, Aldridge focuses on a number of important factors including the attitude of the press towards early television and examines the way that expectations of television changed over time prior to its official launch. Utilising new research, this illuminating study examines how the aims for a new television service developed, and the extent to which content and technology were linked. The Birth of British Television approaches this formative period from several perspectives, from private individuals to the BBC and government, while also examining the broader opinions at the time towards the new medium through press reports and feedback from the general public. Also included is an assessment of early programming, which helps to offer a new and profound evaluation of the development of early television. Mark Aldridge is a Lecturer in Film and TV Studies at Southampton Solent University, UK. He specialises in British television and both film and television history. His previous publications include T is for Television (2008), an analysis of the work of Russell T. Davies, co-written with Andy Murray.
