Excerpt from Nautical Science: In Its Relation to Practical Navigation, Together With a Study of the Tides and Tidal Currents
His work is intended for the general reader as well as for the practical navigator. It is an attempt to explain in non-technical language and without the use Of complicated mathematical formulas the fundamental facts and principles that form the basis Of all navigational methods. Navigation is founded upon Astronomy, but it is not essential for the navigator, in order to find his way from port to port, to know the methods by which the size, the shape, and the motions Of the earth are determined, and to be familiar with the physical characteristics Of the sun and stars. A knowledge of these astronomical facts is, however, necessary to those who wish to be thoroughly posted in the science of navigation. Every navigator knows how to use the data found in the Nautical Almanac, but few have the slightest idea how these data are collected and made available for the immediate needs Of the practical sailor.
The Sumner method of finding one's position at sea is fundamental and, when combined with modern methods of reduction, is most simple and readily applied to all navigational problems.

Verkäuferbewertung 4 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book provides a simplified guide to nautical science for both navigators and general readers. Starting with the basics of spherical geometry and Earth science, the author explains the principles of astronomy and timekeeping necessary for celestial navigation. By using the positions of celestial bodies, the author explains how mariners find their latitude and longitude on the open seas. The book includes detailed explanations of the tides and tidal currents. Starting with the simple concept of the Moon's pull on the tides, the author explains the complex systems that determine real-world tides. These concepts are illustrated with maps of co-tidal lines and co-current lines, which show the rate and direction the tide moves around the globe. The author, Charles Lane Poor, was a respected professor of astronomy at Columbia University. He was also an expert navigator and a Fellow of the Royal Geographical Society. His writing is non-technical and accessible, even to readers with no background in science. His explanations are clear and engaging, making this book a valuable resource for sailors, students, and anyone else interested in learning about the history and science of navigation. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
