Sextants at Greenwich


Book Description

Sextants at Greenwich consists of two main sections: The introductory chapters and the catalogue of navigating instruments of the National Maritime Museum. The first section gives a general overview of the history of celestial navigation with an emphasis on the instruments that were developed and used for that purpose, between about 1450 and the 1970s. The instruments in the catalogue form the main thread in these chapters. The catalogue consists of 347 entries of instruments for celestial navigation, the octants, sextants and related instruments preserved in the National Maritime Museum. Each entry includes the place of the object's origin, its maker, the object's date, inscriptions (by the maker and/or relating to an owner), the graduated scale, the instrument's dimensions and a general description that includes details such as used materials and detached parts. Finally the object's provenance (previous owners and/or users) and references to literature on its history and handling are given.

Kew Observatory and the Evolution of Victorian Science, 1840–1910


Book Description

Kew Observatory was originally built in 1769 for King George III, a keen amateur astronomer, so that he could observe the transit of Venus. By the mid-nineteenth century, it was a world-leading center for four major sciences: geomagnetism, meteorology, solar physics, and standardization. Long before government cutbacks forced its closure in 1980, the observatory was run by both major bodies responsible for the management of science in Britain: first the British Association for the Advancement of Science, and then, from 1871, the Royal Society. Kew Observatory influenced and was influenced by many of the larger developments in the physical sciences during the second half of the nineteenth century, while many of the major figures involved were in some way affiliated with Kew. Lee T. Macdonald explores the extraordinary story of this important scientific institution as it rose to prominence during the Victorian era. His book offers fresh new insights into key historical issues in nineteenth-century science: the patronage of science; relations between science and government; the evolution of the observatory sciences; and the origins and early years of the National Physical Laboratory, once an extension of Kew and now the largest applied physics organization in the United Kingdom.
