An Empire Of Magnetism

During the 1840s and 1850s, the British government financed a world-wide investigation into how the Earth's magnetic phenomena operated, consisting of a network of naval expeditions and colonial observatories. Questions surrounding terrestrial magnetism were not just philosophical, but engendered urgent concerns over accurate navigation, on which Britain's commercial and colonial power relied. The British Magnetic Survey was celebrated at the time as the most extensive state-orchestrated scientific enterprise ever conducted. Yet although it was a fundamentally global endeavour, both in terms of its scale and its impact, the experimental instruments and techniques required were to be found amid Britain's booming local industry, where the harnessing of coal and iron, and use of steam power, shaped a scientific culture prominently concerned with the relationship between heat, pressure, and motion. In particular, it was philosophical apparatus fashioned within the mines of Cornwall that the government was able to conscript within this world-wide magnetic investigation. These locally produced experimental techniques and technologies proved capable of transformation into a system for obtaining magnetic measurements from over great expanses of time and space. As An Empire of Magnetism demonstrates, this not only sustained an immense world-wide scientific investigation, but became inseparable from the proliferation of empire, sustaining colonial expansion and unprecedented multi-cultural exchanges as British naval crews and natural philosophers surveyed previously unknown regions in the search for magnetic data. In so doing, Edward Gillin argues that the British Magnetic Survey had broader implications over the formation of the 'modern state', the expansion of nineteenth-century empire, and the development of global science.

This book offers an in-depth, global history of the British Magnetic Survey - the nineteenth-century, British-government-funded efforts to measure and understand the earth's magnetic field. These scientific efforts are situated within the context of the development of 'global science' and the ways they intersected with empire and colonialism.

Engineers are empire-builders. Watt, Brunel, and others worked to build and expand personal and business empires of material technology and in so doing these engineers also became active agents of political and economic empire. This book provides a fascinating exploration of the cultural construction of the large-scale technologies of empire.

A Pulitzer Prize–winning author examines South Pole expeditions, “wrapping the science in plenty of dangerous drama to keep readers engaged” (Booklist). An Empire of Ice presents a fascinating new take on Antarctic exploration—placing the famed voyages of Norwegian explorer Roald Amundsen, his British rivals Robert Scott and Ernest Shackleton, and others in a larger scientific, social, and geopolitical context. Recounting the Antarctic expeditions of the early twentieth century, the author reveals the British efforts for what they actually were: massive scientific enterprises in which reaching the South Pole was but a spectacular sideshow. By focusing on the larger purpose of these legendary adventures, Edward J. Larson deepens our appreciation of the explorers’ achievements, shares little-known stories, and shows what the Heroic Age of Antarctic discovery was really about. “Rather than recounting the story of the race to the pole chronologically, Larson concentrates on various scientific disciplines (like meteorology, glaciology and paleontology) and elucidates the advances made by the polar explorers . . . Covers a lot of ground—science, politics, history, adventure.” —The New York Times Book Review
