Pulsars are rapidly spinning neutron stars, the collapsed cores of once massive stars that ended their lives as supernova explosions. In this book, Geoff McNamara explores the history, subsequent discovery and contemporary research into pulsar astronomy. The story of pulsars is brought right up to date with the announcement in 2006 of a new breed of pulsar, Rotating Radio Transients (RRATs), which emit short bursts of radio signals separated by long pauses. These may outnumber conventional radio pulsars by a ratio of four to one. Geoff McNamara ends by pointing out that, despite the enormous success of pulsar research in the second half of the twentieth century, the real discoveries are yet to be made including, perhaps, the detection of the hypothetical pulsar black hole binary system by the proposed Square Kilometre Array - the largest single radio telescope in the world.
For those interested in science, technology, or history, or anyone who’s ever wondered about the instruments that divide our days into moments: the time you spend reading this book may fly, and it is certain to be well spent.
Reproductions of ancient documents alongside photographs of timekeeping instruments such as sundials, clocks, pocket watches and wristwatches with astronomical functions illustrate the text, which also includes explanations of the Nebra sky ...
The small area around Whitefriars, mentioned earlier, was a hotbed of crime, bullying and sloth. A famous murder took place here. Lord Sanquhar, a Scottish nobleman, had his eye put out by accident by a fencing master, John Turner.
This book offers perspectives on the interplay between short-term timekeeping technologies and their social contexts in ancient Egypt, Babylon, Greece, and Rome.
