This book explores the development of navigation in the eighteenth and nineteenth centuries. It examines the role of men of science, seamen and practitioners across Europe, and the realities of navigational practice, showing that old and new methods were complementary not exclusive, their use dependent on many competing factors.

Space and time on earth are regulated by the prime meridian, 0°, which is, by convention, based at the Royal Observatory, Greenwich. But the meridian’s location in southeast London is not a simple legacy of Britain’s imperial past. Before the nineteenth century, more than twenty-five different prime meridians were in use around the world, including Paris, Beijing, Greenwich, Washington, and the location traditional in Europe since Ptolemy, the Canary Islands. Charles Withers explains how the choice of Greenwich to mark 0° longitude solved complex problems of global measurement that had engaged geographers, astronomers, and mariners since ancient times. Withers guides readers through the navigation and astronomy associated with diverse meridians and explains the problems that these cartographic lines both solved and created. He shows that as science and commerce became more global and as railway and telegraph networks tied the world closer together, the multiplicity of prime meridians led to ever greater confusion in the coordination of time and the geographical division of space. After a series of international scientific meetings, notably the 1884 International Meridian Conference in Washington, DC, Greenwich emerged as the most pragmatic choice for a global prime meridian, though not unanimously or without acrimony. Even after 1884, other prime meridians remained in use for decades. As Zero Degrees shows, geographies of the prime meridian are a testament to the power of maps, the challenges of accurate measurement on a global scale, and the role of scientific authority in creating the modern world.

Since its launch in 1987, the History of Cartography series has garnered critical acclaim and sparked a new generation of interdisciplinary scholarship. Cartography in the European Enlightenment, the highly anticipated fourth volume, offers a comprehensive overview of the cartographic practices of Europeans, Russians, and the Ottomans, both at home and in overseas territories, from 1650 to 1800. The social and intellectual changes that swept Enlightenment Europe also transformed many of its mapmaking practices. A new emphasis on geometric principles gave rise to improved tools for measuring and mapping the world, even as large-scale cartographic projects became possible under the aegis of powerful states. Yet older mapping practices persisted: Enlightenment cartography encompassed a wide variety of processes for making, circulating, and using maps of different types. The volume’s more than four hundred encyclopedic articles explore the era’s mapping, covering topics both detailed—such as geodetic surveying, thematic mapping, and map collecting—and broad, such as women and cartography, cartography and the economy, and the art and design of maps. Copious bibliographical references and nearly one thousand full-color illustrations complement the detailed entries.

As he prepared to embark for India in 1774, Alexander Mackrabie's excitement at the sights to be seen and novelties to be experienced was palpable. Mackrabie's journey was conducted under the auspices of the London-based East India Company and was one of the many thousands of Company voyages that brought Europeans into contact with Asian countries and cultures, as well as numerous people and places along the way. Atlantic Voyages tells the story of travellers like Mackrabie as they navigated the waters of the Atlantic Ocean, reflecting on who and what they had left behind in Europe, looking forward to new challenges in Asia, and evaluating the sights and smells, sounds and tastes, hopes and expectations, fears and regrets, that regaled their senses and played on their minds as they sailed along the way. It charts the tension between tedium and terror on the one hand, and exhilaration and excitement on the other, attempting to understand the maritime space of the Atlantic as it was experienced by the people who traversed its waters. The lives of the people carried by East Indiamen were deeply affected by their Atlantic experiences. They confronted the reality of shipboard life: its seasickness and boredom, its cramped living conditions, its questionable dining fare, and its severely restricted privacy. They acclimatised to the rhythms of the ocean and the vicissitudes of the weather. They encountered rites of passage and ceremonies of initiation on the high seas. They prepared themselves for cultural disorientation and a host of unusual sights and sensations. And they wondered at the extraordinary beauty of the elements around them - the sea, the sky, the islands - and the strangeness of their inhabitants, human and animal alike. The ship's passage played a crucial role in shaping the responses and experiences of those individuals surrounded by its wooden walls. Their words bring to life this maritime journey, illuminate the experiences of the people who undertook it, and contribute to our understanding of the place of the Atlantic Ocean in wider histories of the East India Company and the British Empire in this period.

Exploring distinctive practices in the artisanal, mercantile, and governmental sites of London, Metropolitan Science offers a new perspective on the development of a scientific culture between the years 1600-1800. Beginning with the demographics of London in the 17th and 18th centuries, including its attraction of migrants, importance as a centre of empire, and the role of its institutions in government, the authors analyse how and why London was a unique site of scientific activity. Through the use of case studies, such as the Tower of London's Royal Mint, and the Livery Company Halls, this book examines the city's sites of exchange for knowledge and practice, and highlights the importance of both public and private spaces. With exploration of London's military and colonial history, the authors acknowledge how its port and maritime trade were not only central to growth and protection, but also facilitated the organisation, assessment, valuation, and pursuit of knowledge in the city. Ultimately, this book demonstrates that London corporations produced unique knowledge communities that drew on networks across the city and beyond, and uses a variety of spatial and material approaches to reveal the use, representation, and exchange of practice in these collective settings.

This edited volume charts the history of celestial navigation over the course of five centuries. Written by a group of historians and scientists, it analyzes how competing navigation systems, technologies, and institutions emerged and developed, with a focus on the major players in the US and the UK. The history covers the founding of the Royal Observatory; the first printing of a Nautical Almanac; the founding of the US and UK Nautical Almanac Offices; the creation of international standards for reference systems and astronomical constants; and the impact of 20th century technology on the field, among other topics. Additionally, the volume analyzes the present role and status of celestial navigation, particularly with respect to modern radio and satellite navigation systems. With its diverse authorship and nontechnical language, this book will appeal to any reader interested in the history of science, technology, astronomy, and navigation over the ages.

Through ten case studies by international specialists, this book investigates the circulation and production of scientific knowledge between 1750 and 1945 in the fields of agriculture, astronomy, botany, cartography, medicine, statistics, and zoology. In this period, most of the world was under some form of imperial control, while science emerged as a discrete field of activity. What was the relationship between empire and science? Was science just an instrument for imperial domination? While such guiding questions place the book in the tradition of science and empire studies, it offers a fresh perspective in dialogue with global history and circulatory approaches. The book demonstrates, not by theoretical discourse but through detailed historical case studies, that the adoption of a global scale of analysis or an emphasis on circulatory processes does not entail analytical vagueness, diffusionism in disguise, or complacency with imperialism. The chapters show scientific knowledge emerging from the actions of little-known individuals moving across several Empires—European, Asian, and South American alike—in unanticipated places and institutions, and through complex processes of exchange, competition, collaboration, and circulation of knowledge. The book will interest scholars and undergraduate and graduate students concerned with the connections between the history of science, imperial history, and global history.
