Excerpt from The Mathematics of Navigation
To the beginner, navigation seems a maze of formulas, a mass of tables and a long list of funny names. In fact, the extremely confused and complicated way of presenting the subject reminds the author of the examinations a licensed electrician has to pass, which are apparently gotten up to reduce the number of licensed electricians. Many who navigate ships are poor mathematicians, and though they may be fine men, good sailors and eficient oficers they are so in spite of their poor mathematics, not because of it. Navigation is a mathematical subject and should be so taught. N 0 one can understand navigation unless he knows some mathematics - arithmetic, geometry, algebra, analytical geometry and plane trigonometry. The author does not consider spherical geometry and trigonometry necessary, and thinks they should be avoided, as will be seen, but it is absolutely necessary that the general astro nomical situation be comprehended. Any one who knows astronomy can skip the chapter headed Right Ascension, as it was written only to cover this point.

Paperback. Zustand: New. Print on Demand. This book provides a sharp and yet concise description of celestial navigation. The author introduces new and easier methods, showing that a navigator can obtain his location by simple arithmetic with an accuracy that is well within his requirements. Those who sail the seas, navigators, astronomers, and all interested in astronomy will find the book easy to understand and follow. The author does not assume any prior knowledge of spherical trigonometry and geometry, instead relying on simple algebra, and plane trigonometry and demonstrating the application of differential calculus. Navigation is a mathematical subject, and must be so taught, and the author shows how by simplifying the complex subject of celestial navigation, it is possible to understand and use the equations with complete confidence and accuracy.
