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.

This eleventh edition was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time and it is considered to be a landmark encyclopaedia for scholarship and literary style.

The popular Rookie Books expand their horizons - to all corners of the globe! With this series all about geography, emergent readers will take off on adventures to cities, nations, waterways, and habitats around the world...and right in their own backyards.

Rufus McGaugh knew early on that he wanted to see the world-all of it. And, later on, he did just that.Longitude and Latitude, with Attitude chronicles Rufus's 49 years of travels around the globe to every country in the world. It relates his experiences, both harrowing and humorous, in entertaining and amusing (sometimes even instructive!) vignettes.Rufus, a Vietnam vet who was awarded the Purple Heart in 1970, became a Vietnam vet against the war, got a college degree, and taught social studies at Brownell Middle School in the affluent Detroit suburb of Grosse Pointe for 39 years. During that time-and before and after-he spent his summers, vacations, and retirement fulfilling a life-long dream to travel to every corner of the Earth. He has visited countries near and far, well known and obscure (including the closed regimes of North Korea and Libya). He has met interesting people, seen fascinating sights, and observed unusual events.He has been hassled by the authorities in Russia (twice in one day). He was arrested-and later stalked by a leopard-in Zimbabwe. He met Miss America (well, Miss South Carolina) in Vietnam, outfoxed (or so he thought) a tailor in Hong Kong, and broke both arms bicycling in Cuba.Longitude and Latitude, with Attitude is the unpretentious, often comic, frequently informative chronicle of these and other adventures and misadventures he experienced on his journeys. Other wanderers like him-and armchair travelers everywhere-will be captivated by it. The lively writing is supplemented by more than 50 pictures that inveterate photographer Rufus has taken in the course of his trips.

Explains the concepts of latitude and longitude as well as the purpose of the compass rose on a map.

Excerpt from Latitude and Longitude: How to Find Them This series has been designed to meet the growing desire on the part of Officers in the Mercantile Marine for a more scientific insight into the principles of their pro fession, and the sciences upon which the Art of Navigation is founded. The treatises are, for the most part, written BY sailors for sailors; and, where this is not the case, by authors who have special knowledge of the subjects dealt with and their application to the Sailor's life. The treatment will be thoroughly scientific, yet as free as pos sible from abstruse technicalities, and the style such as will render it easy for the young sailor to gain a knowledge of the elements of his profession by private reading and without difficulty.

Latitude is a gloriously exciting tale of adventure and scientific discovery that has never been told before. Crane, the former president of the Royal Geographic Society, documents the remarkable expedition undertaken by a group of twelve European adventurer-scientists in the mid-eighteenth century. The team spent years in South America, scaling volcanoes and traversing jungles before they achieved their goal of establishing the exact shape of the Earth by measuring the length of 1 degree latitude at the equator. Their endeavors were not limited to this one achievement. Not only did their discovery open up the possibility for safe, accurate navigation across the seas, they also discovered rubber and quinine. With a narrative that reads like it was taken from the script of an adventure movie, Nicholas Crane brings to life a narrative that is a timely remind of how scientific discovery can change the world and our future. By knowing the shape of the earth we can create maps, survive the oceans, navigate the skies, and travel across the globe. Without latitude, maps and navigation wouldn’t be accurate, lives would have been lost, and exact locations of cities and rivers would never be known. After ten grueling years in search of a magic number, the survivors returned to Europe with their historical discovery and fueled the public’s interest in science. Twent-five years ago, Dava Sobel’s bestselling Longitude was a global publishing phenomenon, yet it told only one half of the story. With Latitude, this cornerstone piece of our shared history is now complete with this tale of a trip that changed the course of human civilization. Filled with raw excitement and danger, Latitude brings the challenges that faced these explorer-scientists to vivid life.

Official publication of the National Maritime Museum's exhibition "Ships, Clocks and Stars: The Quest for Longitude". 300 years ago, amidst growing frustration from the naval community and pressure from the increasing importance of international trade, the British government passed the 1714 Longitude Act. It was an attempt to solve one of the most pressing problems of the age: how to determine a ship's longitude (east-west position) at sea. With life-changing rewards on offer, the challenge captured the imaginations and talents of astronomers, skilled craftsmen, politicians, seamen and satirists. This beautifully illustrated book is a detailed account of these stories, and how the longitude problem was solved. Highlights of the book include: * Foreword by the fifteenth Astronomer Royal, Martin Rees. * Specially commissioned photographs of the National Maritime Museum's collection. * A new description of the collaborations and conflicts in a tale of technical creativity, scientific innovation and hard commercialism. From the same publisher as Dava Sobel's Longitude, Finding Longitude tells a new story of one of the great achievements of the Georgian age, and how it changed our understanding of the world.

Even in such a tech-savvy culture as ours, understanding latitude and longitude coordinates has many uses. Coordinates can help hikers find their way when lost on a difficult trail and geocache enthusiasts locate their treasure. Even more importantly, they can help communicate location no matter what language is being spoken. Readers learn all about the development, use, and accuracy of the grid mapping system of latitude and longitude. Covering the equator, Prime Meridian, and more, the main content complements important topics from the social studies curriculum. Full-color maps aid readers’ understanding as fact boxes clarify key information.
