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.

James Clerk Maxwell published the Treatise on Electricity and Magnetism in 1873. At his death, six years later, his theory of the electromagnetic field was neither well understood nor widely accepted. By the mid-1890s, however, it was regarded as one of the most fundamental and fruitful of all physical theories. Bruce J. Hunt examines the joint work of a group of young British physicists—G. F. FitzGerald, Oliver Heaviside, and Oliver Lodge—along with a key German contributor, Heinrich Hertz. It was these "Maxwellians" who transformed the fertile but half-finished ideas presented in the Treatise into the concise and powerful system now known as "Maxwell's theory."

"In Sound Authorities, Edward J. Gillin shows how experiences of music and sound played a crucial role in nineteenth-century scientific inquiry in Britain. Where other studies have focused on vision in Victorian England, Gillin focuses on hearing and aurality, making the claim that the development of the natural sciences in Britain in this era cannot be understood without attending to how the study of sound and music contributed to the fashioning of new scientific knowledge. Gillin's book is about how scientific practitioners attempted to fashion themselves as authorities on sonorous phenomena, coming into conflict with traditional musical elites as well as religious bodies. Gillin pays attention to not only musical sound but also the phenomenon of sound in non-musical contexts, specifically, the cacophony of British industrialization, and he analyzes the debates between figures from disparate fields over the proper account of musical experience. Gillin's story begins with the place of acoustics in early nineteenth-century London, examining scientific exhibitions, lectures, and spectacles, as well as workshops, laboratories, and showrooms. He goes on to explore how mathematicians mobilized sound in their understanding of natural laws and their vision of a harmonious order, as well as the convergence of aesthetic and scientific approaches to pitch standardization. In closing, Gillin delves into the era's religious and metaphysical debates over the place of music (and humanity) in nature, the relationship between music and the divine, and the tension between religious/spiritualist understandings of sound and scientific/materialist ones"--

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

The Garden of Leaders explores two related questions: What is leadership? And what sort of education could prepare young people to be leaders? Paul Woodruff argues that higher education--particularly but not exclusively in the liberal arts--should set its main focus on cultivating leadership in students. Woodruff advances a new view of liberal arts education that places leadership at the root of everything it does, so that students will be prepared to lead in their lives and careers--and not necessarily in management roles. Woodruff views the contemporary university as sorely lacking an emphasis on leadership, and presents three core sets of recommendations for how they can and should foster it. First, Woodruff posits co-curricular groups, activities, and projects as essential activities for students to gain confidence and leadership skills. Administrations should encourage students to engage in activities outside the classroom, convert coached sports teams into student-led clubs as far as possible, and discourage social organizations that are segregated by race or sex. Second, Woodruff advocates for a different curriculum for all undergraduates, no matter their major-arguing that they need to be taught leadership in the forms of key skills including communication (including good writing, listening, and speaking), as well as exposure to key material in history literature, social science, and ethics. Students should be asked to consider the hardest ethical dilemmas that leaders face, toggling between Machiavelli and great ethical thinkers such as Confucius and Socrates. Third, Woodruff calls for the teaching methods used by instructors to re-orient themselves around the question of leadership, particularly by emphasizing teamwork. Professors should respect their students' independence, avoid tyrannical teaching, and remember that all teachers teach ethics simply by the examples they set in dealing with students. Whether in engineering, music, or classics, The Garden of Leaders advances leadership as a core value that should be at the heart of the educational enterprise-contending that while a college campus can be many things, it should at the very least be a ground upon which new leaders can grow.

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.
