Book Description
Today travellers by land, sea and air take accurate navigation for granted but it was not always thus. The author, a highly experienced sailor, sets out to record the development of navigational techniques from the earliest time, five millenniums ago. As explorers started to venture offshore into the unknown they had to rely on the sun and stars for direction. From this pioneers turned to mathematics, astrolobes, sextants and increasing accurate clocks to measure latitude and later longitude. More recently major breakthroughs with electronic navigation, GPS and other satellite systems have revolutionised travel. Focusing primarily but not exclusively on marine navigation, the author weaves a fascinating course through the successes and failures of mankind's quest to explore his world. The result is a thoroughly entertaining and informative work which has no rival.

Book Description
If you want to know where you are, you need a good clock. The surprising connection between time and placeais explored inaTime and Navigation- The Untold Story of Getting from Here to There, the companion book to the National Air and Space Museum exhibition of the same name. Today we use smartphones and GPS, but navigating has not always been so easy. The oldest "clock" is Earth itself, and the oldest means of keeping time came from observing changes in the sky. Early mariners like the Vikings accomplished amazing feats of navigation without using clocks at all. Pioneering seafarers in the Age of Exploration used dead reckoning and celestial navigation; later innovations such as sextants and marine chronometers honed these techniques by measuring latitude and longitude. When explorers turned their sights to the skies, they built on what had been learned at sea. For example, Charles Lindbergh used a bubble sextant on his record-breaking flights. World War II led to the development of new flight technologies, notably radio navigation, since celestial navigation was not suited for all-weather military operations. These forms of navigation were extended and enhanced when explorers began guiding spacecraft into space and across the solar system. Astronauts combined celestial navigation technology with radio transmissions. The development of the atomic clock revolutionized space flight because it could measure billionths of a second, thereby allowing mission teams to navigate more accurately. Scientists and engineers applied these technologies to navigation on earth to develop space-based time and navigation services such as GPS that is used every day by people from all walks of life. While the history of navigation is one of constant change and innovation, it is also one of remarkable continuity. Time and Navigation tells the story of navigation to help us understand where we have been and how we got there so that we can understand where we are going.

Book Description
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.

Book Description
This book is a collection of essays addressing multiple aspects of African maritime history in attempt to counter the lack of academic research that exists in comparison to other nations and continents, and to assert the value of African topics to the global study of maritime history. Each essay addresses African maritime history whilst also demonstrating an inextricable link to the global maritime stage. The topics discussed include early human migration to Africa; early European contact with Africa; the role of West African maritime communities in the Atlantic slave trade; New World slaveholders and the exploitation of African maritime skillsets; the construction of Atlantic world racial discourses; the rise and fall of colonial rule; and African immigrant communities in Europe. These essays cover maritime topics such as seafaring labour, navigational technology, swimming, diving, surfing; plus political subjects that include colonisation, decolonisation, immigration and citizenship. The book consists of eight essays and an introduction that evaluates the existing research into African maritime history. It includes case studies from every major geographical part of the continent, bar North Africa, and covers the Early Modern period up to the twentieth century. The purpose is not to provide a comprehensive chronological history, but rather a diverse collection of topics across a range of periods and locations to reflect the wealth of maritime topics in the history of Africa and their global significance. It concludes with a call for further research into non-European maritime activity, to deepen the global historiography.

Book Description
Historical Perspectives on East Asian Science, Technology, and Medicine brings together over fifty papers by leading contemporary historians from more than a dozen nations. It is the third in a series of books growing out of the tri-annual International Conference on the History of Science in East Asia, the largest and most prestigious gathering of scholars in the field. The current volume broadens the field's traditional focus on China to include path-breaking work on Vietnam, Korea, Japan, the Philippines, and even the transmission of Asian science and technology to Europe and the United States. Topics covered include: traditional Chinese, Vietnamese, and Filipino medicines; Chinese astronomy; Japanese earthquakes; science and technology policy; architecture; the digital revolution; and much else.
