The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.
When Ariel Farwalker hears the moon talking to her, she thinks she must be going crazy. Then she discovers an ancient map, and learns that the moon is part of a mysterious summons that's calling her on a new journey. With her surly guardian Scarl by her side, Ariel sets out on an adventure that leads her to new friends-the beautiful Flame-Mage Sienna and the mute boy Nace, who captures Ariel's heart. As the four travel on, strange things start to happen-fragments of Ariel's past appear in the present, so that it seems that time itself is coming undone. At the end of the journey, Ariel will learn where her journey began, and have a chance to save her life as she knows it.
Whatever had destroyed the dinosaurs was approaching Earth again. 20 extraordinary people find that they have 4 years to prevent a catastrophe, but they know that the administration will not believe them, from previous experience. When their 4-year-older timeline connects with them in a bid to prevent the annihilation of Earth in their timeline, they are elated. However, when the older timeline stops responding after a while, they assume that it has succumbed. Their stumbling journey to prevent the catastrophe takes them to Africa and then the Pacific Islands. However, they are up against a technology that was far more advanced even 66 million years ago. In desperation, they reach out eight generations into their own past, risking their present to find a solution. Do they succeed, or does humanity go extinct the way the dinosaurs did?

A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamental, new and original research.
This remarkable work is a comprehensive historiographical and bibliographical survey of the most important scholarly and printed materials about the naval and maritime history of England and Great Britain from the earliest times to 1815. More than 4,000 popular, standard and official histories, important articles in journals and periodicals, anthologies, conference, symposium and seminar papers, guides, documents and doctoral theses are covered so that the emphasis is the broadest possible. But the work is far, far more than a listing. The works are all evaluated, assessed and analysed and then integrated into an historical narrative that makes the book a hugely useful reference work for student, scholar, and enthusiast alike. It is divided into twenty-one chapters which cover resource centres, significant naval writers, pre-eminent and general histories, the chronological periods from Julius Caesar through the Vikings, Tudors and Stuarts to Nelson and Bligh, major naval personalities, warships, piracy, strategy and tactics, exploration, discovery and navigation, archaeology and even naval fiction. Quite simply, no-one with an interest and enthusiasm for naval history can afford to be without this book at their side.
At Les Houches in January 2015, experts in the field of charged particle trapping came together for the Second Winter School on Physics with Trapped Charged Particles. This textbook collates the lectures delivered there, covering the fundamental physics of particle traps and the different types of applications of these devices.Taken as a whole, the book gives an overview of why traps for charged particles are important, how they work, their special features and limitations, and their application in areas such as precision measurements, mass spectrometry, optical clocks, plasma physics, antihydrogen creation, quantum simulation and quantum information processing. Chapters from various world experts include those on the basic properties of Penning traps and RF traps, as well as those covering important practical aspects such as vacuum systems, detection techniques, and different types of particle cooling, including laser cooling.Each individual chapter provides information and guidance on the application of the above methods. Additionally, each chapter is complemented by fully worked problems and solutions, making Trapped Charged Particles perfect for advanced undergraduate and postgraduate students new to this topic.
