Download or read book Our Celestial Clockwork From Ancient Origins To Modern Astronomy Of The Solar System written by Richard Kerner and published by World Scientific. This book was released on 2021-08-24 with total page 503 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a superposition of two distinct narratives: the first is historical, discussing the evolution of astronomical knowledge since the dawn of civilizations; the second is scientific, conveying mathematical and physical content of each advancement. Great scientists of antiquity, Middle Ages and modern times until the 18th century, are presented along with their discoveries, through short biographies and anecdotes. Special care is taken to explain their achievements using mathematical and physical concepts of their time, with modern perspective added only when ancient methodology is too cumbersome or its language hardly understandable to contemporary readers.The book conveys a lot of astronomical facts and data in a pleasant and accessible manner. Almost all findings and discoveries made in ancient times are followed by simple mathematical exercises using basic knowledge, so that the reader can check the assertions himself. The book contains a lot of inedited illustrations. Geometrical schemes are given extra attention to make the examples clear and understandable. The language is simple and accessible to the young audience.
Download or read book Sextant written by David Barrie and published by Harper Collins. This book was released on 2014-05-13 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the tradition of Dava Sobel's Longitude comes sailing expert David Barrie's compelling and dramatic tale of invention and discovery—an eloquent elegy to one of the most important navigational instruments ever created, and the daring mariners who used it to explore, conquer, and map the world. Since its invention in 1759, a mariner's most prized possession has been the sextant. A navigation tool that measures the angle between a celestial object and the horizon, the sextant allowed sailors to pinpoint their exact location at sea. David Barrie chronicles the sextant's development and shows how it not only saved the lives of navigators in wild and dangerous seas, but played a pivotal role in their ability to map the globe. He synthesizes centuries of seafaring history and the daring sailors who have become legend, including James Cook, Matthew Flinders, Robert Fitz-Roy, Frank Worsley of the Endurance, and Joshua Slocum, the redoubtable old "lunarian" and first single-handed-round-the-world yachtsman. He also recounts his own maiden voyage, and insights gleaned from his experiences as a practiced seaman and navigator. Full of heroism, danger, and excitement, told with an infectious sense of wonder, Sextant offers a new look at a masterful achievement that changed the course of history.

Download or read book Longitude written by Dava Sobel and published by Bloomsbury Publishing USA. This book was released on 2010-07-05 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: From the New York Times-bestselling author of The Secret World of Weather and The Lost Art of Reading Nature’s Signs, learn to tap into nature and notice the hidden clues all around you Before GPS, before the compass, and even before cartography, humankind was navigating. Now this singular guide helps us rediscover what our ancestors long understood—that a windswept tree, the depth of a puddle, or a trill of birdsong can help us find our way, if we know what to look and listen for. Adventurer and navigation expert Tristan Gooley unlocks the directional clues hidden in the sun, moon, stars, clouds, weather patterns, lengthening shadows, changing tides, plant growth, and the habits of wildlife. Rich with navigational anecdotes collected across ages, continents, and cultures, The Natural Navigator will help keep you on course and open your eyes to the wonders, large and small, of the natural world.

Download or read book Just Sea and Sky written by Ben Pester and published by A&C Black. This book was released on 2013-08-04 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This charming account of the voyage of two men in a small boat half way round the world from Plymouth to New Zealand in 1953 is a rare insight into a time, not long ago, when sailors had no GPS, electronics, radio or any of the mod cons that we take for granted today. Without lifejacket or a liferaft, they 'just took what came along', hand steering all the way, navigating by sextant, hand-cranking their engine and using oil lamps for light at night and for navigation. Sailors will be staggered how primitive conditions were only a few decades ago, even though it was the norm at the time. Part travelogue and part adventure story, the two friends encountered drunken harbourmasters, the mafia, the legacy of slavery and lost civilisations in the Pacific. Beautifully written, vivid in its descriptions of the two men's exploits ashore and on board, this quirky and entertaining book will be a fascinating read for sailors and non-sailors alike.

Download or read book The Practical Guide to Celestial Navigation written by Phil Somerville and published by Bloomsbury Publishing. This book was released on 2021-10-14 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: THIS EBOOK EDITION IS DESIGNED TO BE EXPERIENCED ON COLOUR DEVICES The practical guide to celestial navigation - know what to do step by step, understand why you're doing it, and be confident that you can put it into practice when on board. Did you know that a person standing on the equator is effectively travelling at 900mph? And did you know that you can use this information to work out where you are in the world, to an accuracy of about 3 or 4 miles? No GPS, no computers. Just a sextant, some tables from an Almanac and the knowledge in this book. It's the only back up if the GPS goes down, so it's a matter of safety. If you want to qualify as a commercial skipper/superyacht captain you need to know how to carry out celestial navigation. And if you want to pass the RYA Ocean YachtmasterTM exam, you need to know it too. It's a major stumbling block for many sailors wanting or needing to take their next qualifications, and the other books on the market are complex and often assume some prior understanding. This book fulfils the need for a clear explanation of celestial navigation, illustrated with colour diagrams and including unique checklist sheets to enable you to repeat all those calculations you learned back at home, when you're on deck. Without overwhelming the reader with a load of theory from the off, the author breaks down what you need to do, step by step, explaining why at every point – giving the information context, and making it more interesting and memorable. He has trained students in this subject for years, and here he's able to use his experiences of what works, and what are the common pitfalls – he even includes a troubleshooting chapter near the end, going through errors commonly made, and how to spot them. The objective is that readers will finish the book not only knowing what to do, but really understanding why, and being able to make sense of it all again later (rather than just getting through and exam and finding themselves at a loss when on deck). The author also includes time-tested 'proformas' – quick reference sheets that sailors can refer to when they come to putting the theory into practice on board, avoiding the terrifying 'cold start' that most sailors experience when they suddenly need to put their theoretical knowledge to the test in the real world.
